Description

The clamp connection of belt conveyor The present invention relates to the mechanical grip attaching parts that is used for conveyor belt ends, make it to become the belt conveyor of ring-type; Be specially adapted to the belt elevator, wherein belt ends bends out from the plane of movement of belt conveyor, and the belt ends frictionally is clamped between two drip moldings at least, and these two drip moldings block belt conveyor.These drip moldings connect with a screw attaching parts at least and give tightly, and this screw passes the drip molding that is positioned at the belt conveyor both sides. Such clamping means were described in DE-PS, also mentioned the problem that this clamped joint exists in the literary composition, because the rubber that is between the drip molding skids or plastic deformation, cause during use according to this clamped joint giving tight power and in use can reduce by the screw generation.If this state is not tightened screw and is eliminated in good time, danger will appear, if promptly give tight power drop to be lower than the friction desired certain limit, the motion of clamp connection engages and will weaken, and belt conveyor is understood slippage or is made screw extraction, clamp connection can't clip belt conveyor like this, and the result can tear belt conveyor. In order to overcome this shortcoming, narrated the tensioning state that a kind of special device is used for monitoring the screw attaching parts in the public publication file of mentioning in front, when tension force decline occurring in the screw attaching parts, a kind of special key spare is suitable for selecting for use a trigger signal switch position.This additional device heaviness, be not easy to install and control, particularly do not have enough reliability in the operation, this is because as the triggering transformation point that sends signal, gives earlier the wipe contact of regulation in practice and still can not very accurately determine.For this reason, improving the such fixing device mentioned causes and can differentiate in early days that to give that tight power reduces and tighten attaching parts easily be one object of the present invention. This purpose is realized by following proposal. The present invention is from basic design, being provided with one between screw head in the screw attaching parts and/or nut and the drip molding gives and presses the spring that contracts, its advantage is, since have give press the spring that contracts prevent to tighten in the screw attaching parts screw produced gives weakening of tight power, give pressing the spring that contracts and keeping giving tight state to a great extent.At first, increased the operating reliability of clamped joint, this is because first do not need usually to tighten screw, and this external giving in the fixed defects liability period is held in by suitable allowance is provided in the determined value of experience in order to give tightly to try hard to keep.Can differentiate significantly give in the screw attaching parts tight power to reduce be its additional advantage, this is because compression spring presents long spring movement travel when tightening the screw attaching parts under the sort of situation, like this, with the naked eye just can find out and when need to tighten again screw. According to the present invention, allow only to assemble compression spring in a side of screw attaching parts, for example, only at screw head or nut place.Yet, compression spring all is set also within the scope of the invention at two places between screw head and the drip molding and between nut and drip molding. With regard to clamp connection, it comprises two screw elements arranged side by side on the conveyor belt ends bending direction, and these two screw attaching partss can be installed additional spring.Yet according to one embodiment of present invention, needing only screw attaching parts that has compression spring of installation on each limit of conveyor belt ends also is enough.These compression springs are preferentially selected cup spring for use, also allow to substitute with the spiral compression spring of suitable intensity. Give the cavity that presses the spring that contracts if drip molding has to hold in the place of screw attaching parts installation compression spring, its height is corresponding with the size of giving tight spring assembly, and then the present invention can realize in particularly advantageous mode.If these compression springs are contained in these cavitys; special advantage is by can not entering as the dust brought up by a plurality of scraper bowls respectively on the bucket elevator or a large amount of, free-pouring material among the space of spring, thereby protected the function of compression spring. In order to substitute the cavity on the drip molding, a distance sleeve can be set between attaching screw and drip molding, this puts the auxiliary cavity that holds compression spring. In order further to improve design of the present invention, one packing ring bigger than the diameter that holds helical spring cavity can be installed, it is beneficial especially being used for supporting compression spring and supporting the screw head and the nut that link to each other respectively, makes these screw elements not enter cavity in company with its packing ring. From these special results that advantage produced is just can tentatively tighten screw without dial torque wrench to be pressed in cavity edge set on the drip molding up to the packing ring that adjoins with screw head and/or nut.It is possible providing a definite screw bonded assembly to give tight power in this way from the beginning. If, can cause the compression spring elongation because the rubber creep makes the screw bonded assembly give tight power and reduces.Because and the packing ring that adjoins of screw element and drip molding between the gap has appearred, giving the degree that tight power reduces is appreciiable.When the mode of distinguishing that just can be competent at eyes like this needs to tighten again screw if can being found out.So again, tightening screw is pressed on the drip molding once more up to packing ring.A special actv. detection of tension force degree to the screw attaching parts and simple to operate when tightening screw again is provided in this way. The preferred embodiment of the invention also further provide the screw element that adjoins and the packing ring on the slider disc also have one respectively with drip molding and the close-fitting shoulder shape of the cavity projection that puts, the size of this shoulder shape projection is advantageously greater than the fixed burst size of giving that is contained in spring in the cavity.In this way, in addition since relaxing of spring caused under the situation in gap, also avoided allowing dust or other particle enter cavity inside.This is because these shoulders have extended beyond suitable distance, and cavity still is being tightly sealed with respect to environment on every side. Below in conjunction with accompanying drawing a plurality of working example of the present invention is described. In order to make belt conveyor 10 become the endless belt, its both ends 11,12 are substantially vertically protruding from the plane of movement of belt conveyor 10, and they are force together each other, intermediate member 13 of middle insertion.Intermediate member 13 extend in the sweep of end 11,12 intermediate member 13 also comprising a part 14 by the formed medial extremity of nipping regional end 11,12 of crooked end by its outside face.In the plane of belt conveyor 10, part 14 has and comprises the slightly wide face area of curvature, for example, is used for matching with the belt pulley of the unillustrated belt conveyor 10 of figure. All there is drip molding 15,16 in each outside of 11,12 in the end, the curvature that end 11, the 12 sweeps importing that makes belt conveyor 10 is equally also arranged in its place in the face of the plane of movement of belt conveyor 10, and become straight line gradually, this straight line matches with the end 11,12 of belt conveyor 10 between them perpendicular to the direction of transfer of belt conveyor 10. Two high-strength screws of drip molding 15,16 usefulness connect, and each screw has screw head 18 and nut 19, tightens screw and reaches the suitable tight power of giving.In the embodiment shown in fig. 1, these two screw attaching partss 17 have compression spring 20 between screw head 18 and drip molding 15, and it is tightened by tightening screw 17 equally.Drip molding 15,16 places opposite one another in this case at mounting screw 17, size near belt conveyor 10 plane of movement places is bigger than the size of the screw present position on outer limit, each screw head 18 and each nut 19 can staggeredly be arranged like this, thereby it is close that two screw attaching partss all are easy to, and the tension state of each compression spring in the available eye examination screw attaching parts. Fig. 2 has described additional another working example that changes that has of the present invention.Wherein, each drip molding 15,16 is provided with the cavity 21 that holds compression spring 20 in the place that inboard screw attaching parts 17 is housed.Like this, compression spring 20 all is in the cavity 21 during screw 17 is tightened.With regard to the screw attaching parts 17 in the outside, at drip molding 15,16 respectively and a distance sleeve 25 is set between screw head 18 and the nut 19, at this moment, 21 of the cavitys in the cover hold compression spring 20. Screw head 18 and nut 19 are all supporting a packing ring 22 in the side facing to compression spring 20, and this packing ring 22 is being pressed compression spring 20.The diameter of packing ring 22 is greater than the diameter of cavity 21, so that packing ring 22, screw head 18 and nut 19 can not enter in the cavity 21.Like this, tighten screw attaching parts 17 and be pressed on the drip molding 15,16, on screw attaching parts 17 and compression spring 20, can at first guarantee to produce one and definite give tight power up to packing ring 22.If the tight power of giving of screw attaching parts 17 reduces and makes compression spring 20 be subjected to influence, packing ring 22 is thrown off drip moldings 15,16, has formed an appreciiable gap thus, and this just provides needs to tighten the signal of screw attaching parts again.Yet, tighten screw attaching parts 17 again and be pressed in once more on the drip molding 15,16 without any need for special instrument up to packing ring 22, need dial torque wrench especially usually for this purpose. There is a shoulder 23 in two screw attaching partss 17 point to nut 19 below separately place, and it links to each other with packing ring 22, and it extend in the cavity 21 of drip molding 16 and cover 25.The burst size of the ratio compression spring of the degree of depth selection that they are absorbed in is big, so that when packing ring 22 left drip molding 16 separately and overlaps 25, the gap had formed really, and the minimizing of tight power is given in available thus eyes differentiation.Even so, because shoulder 23 still separates cavity 21 and surrounding environment, extraneous particle still can not enter in the cavity 21.

3 Types of Conveyor Belt Joins

If you want to learn more, please visit our website SINODA.

Conveyor belts are commonly used in various industries for the transportation of goods, materials, and products. The process of joining or repairing conveyor belts often involves methods like cold splicing, hot splicing, or using mechanical belt fasteners or clips. We will explore each of these methods separately.

Hot Splicing:
Process: Hot splicing involves the use of heat to melt or vulcanize a special rubber material to achieve the splice, which is effectively joining the ends of conveyor belts. Where possible, Conveyor Belts Australia seeks to undertake a hot splice. This type of join creates a quality join that is virtually unbreakable. Moreover, the belt can typically be used far more rapidly than other methods. Hot splicing can be challenging on mobile equipment (crushers, screeners etc). At Conveyor Belts Australia, we&#;ve developed methods for achieving a hot splice on a range of common mobile equipment found in the Australian quarry and mining industries. If you are looking for this type of splice, its worth chatting to our team.

Advantages: Hot splicing results in the strongest and most durable connection between the ends of the belt. The process allows the belt to be used with minimal downtime.

Disadvantages: A good splice requires a good team. Many belt teams cannot achieve a hot splice on difficult belts.

Cold Splicing:
Process: Cold splicing is a method of joining conveyor belts without the need for heat. It typically involves the use of a cold adhesive or cement to bond the two belt ends together. This type of splice can produce a very durable join, but often requires a longer period of time for the cement to harden before the belt can be utilised.

Advantages: Cold splicing is often considered convenient and many belt teams can undertake this type of join.

Want more information on Conveyor Connecting Clamps? Feel free to contact us.

Disadvantages: Longer down time required for the belt to be joined safely. The splice is typically strong but not as strong as a hot splice method.

Clips or Mechanical Fasteners:
Process: Mechanical fasteners, such as clips, are metal pieces that are attached to the ends of the conveyor belts. They are typically installed by fastening the clips to the belt ends using bolts or rivets. This kind of method can often be achieved locally by untrained crews. The actual installation of the clips should be completed by a qualified belt team, but the belt can then be installed with limited instructions by the local workforce.

Advantages: Mechanical fasteners are quick to install and do not require special skills or equipment. They are often used in applications where its difficult to get a qualified team out. They can also be used for repairs or pre-prepared belts.

Disadvantages: Some clips are prohibitively expensive. Other clips are much cheaper but can be difficult to install or maintain. Overall clips are convenient but are only a substitute for the above methods described.

Considerations:
The choice between cold splicing, hot splicing, or mechanical fasteners depends on factors such as the application, conveyor belt type, material being transported, and the required strength of the splice. It will often hinge on the quality of advice and service available from your local belt team.
