Description

A conveyor belt tension detection device Technical Field

[0001] This utility model relates to the field of belt tension testing technology, specifically a conveyor belt tension testing device. Background Technology

[0002] Conveyor belts, also known as transport belts, are rubber and fiber / metal composite products, or plastic and fabric composite products, used in belt conveyors to carry and transport materials. The quality of belts is of paramount importance during the production process, and belt tensile testing devices are used to inspect the quality of belts.

[0003] Existing belts are inconvenient to clamp and fix during testing, and are prone to falling off during testing, affecting the testing process. Moreover, they cannot perform tensile testing on conveyor belts of different sizes at the same time, requiring changes to the distance between the belts and the test workpieces, which is cumbersome and results in low testing efficiency.

[0004] Therefore, it is necessary to provide a conveyor belt tension detection device to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this utility model is to provide a conveyor belt tension detection device to solve the problems existing in the background technology. The technical solution of this utility model provides a solution that is significantly different from the existing technology, which is aimed at the problem that the existing technical solutions are too simple.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a conveyor belt tension detection device, comprising a base, a groove being provided at the center of the top of the base, an adjusting rod being rotatably connected inside the groove, external thread groups being equidistantly installed on the outer wall of the adjusting rod, thread seats being threaded at both ends of the outer wall of the external thread groups, and a belt clamping mechanism being installed on the top of the thread seats.

[0007] Preferably, the belt clamping mechanism includes a rectangular ring plate installed on the top of the threaded seat. The front and rear ends of the top of the rectangular ring plate are rotatably connected to threaded rods. A clamping plate is threaded on the top of the outer wall of the threaded rod, and a clamping plate that can move up and down is installed on the bottom of the outer wall of the threaded rod.

[0008] Preferably, the second clamping plate and the threaded rod are movable hollow structures, and a hydraulic rod with a telescopic end connected to the bottom center of the second clamping plate is installed at the center of the inner bottom of the rectangular ring plate.

[0009] Preferably, a drive device for driving the threaded rod to rotate is installed at the rear end of the bottom inner side of the rectangular ring plate, and a pulley is connected to the top of the threaded rod. The outer walls of the two sets of pulleys are provided with transmission belts to form a transmission structure.

[0010] Preferably, the clamping plate one and the clamping plate two can form a clamping structure with different heights.

[0011] Preferably, the external thread assembly is configured as two sets of threads that are symmetrical about the center of the external thread assembly and have opposite directions.

[0012] Any aspects of this utility model not described in detail are well-known technologies to those skilled in the art.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention allows for height adjustment of clamping plate two by controlling the rotation of the threaded rod, thereby controlling the distance between clamping plate two and clamping plate one. This allows for clamping and fixing one end of conveyor belts of different thicknesses. Another set of clamping plates two and clamping plate one can clamp and fix the other end of the conveyor belt, thus clamping and fixing the conveyor belt. Then, by controlling the rotation of the adjusting rod, the threaded seat on the outer wall of the external thread assembly can be moved apart, thereby stretching and testing the conveyor belt to both ends. Through the multiple sets of belt clamping mechanisms, multiple conveyor belts can be tested simultaneously.

[0015] This invention uses a hydraulic rod to control the lifting and lowering of the second clamping plate, and the second clamping plate and the threaded rod are not in contact. The lifting and lowering of the second clamping plate can adjust the height of the conveyor belt clamping and fixing, which is convenient for the subsequent use of multiple sets of belt clamping mechanisms. By lifting and lowering the first clamping plate, not only can the height of the conveyor belt clamping and fixing be controlled, but also, by using multiple sets of first clamping plates with different heights, multiple belt clamping mechanisms can cooperate to clamp and fix longer conveyor belts. Moreover, the tensile testing of conveyor belts of different lengths can be carried out simultaneously, saving time and improving work efficiency. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will be described below based on its overall structure.

[0022] Please refer to Figures 1-3. A conveyor belt tension detection device includes a base 1. A groove 2 is provided at the top center of the base 1. An adjusting rod 3 is rotatably connected inside the groove 2. External thread groups 4 are installed at equal intervals on the outer wall of the adjusting rod 3. Thread seats 5 are threaded at both ends of the outer wall of the external thread group 4. A belt clamping mechanism 6 is installed on the top of the thread seats 5.

[0023] As shown in Figures 1-3, the belt clamping mechanism 6 includes a rectangular ring plate 601 mounted on the top of the threaded seat 5. Threaded rods 602 are rotatably connected to the front and rear ends of the top of the rectangular ring plate 601. A clamping plate 603 is threaded onto the top of the outer wall of the threaded rod 602, and a vertically movable clamping plate 604 is mounted on the bottom of the outer wall of the threaded rod 602. By controlling the rotation of the threaded rod 602, the height of the clamping plate 604 can be adjusted, thereby controlling the distance between the clamping plate 604 and the clamping plate 603. This allows for clamping and fixing one end of a conveyor belt of different thicknesses. Another set of clamping plates 604 and clamping plate 603 can clamp and fix the other end of the conveyor belt, thus clamping and fixing the conveyor belt. Then, by controlling the rotation of the adjusting rod 3, the threaded seat 5 on the outer wall of the external thread group 4 can be driven to move away from each other, thereby stretching and testing the conveyor belt to both ends. Multiple sets of belt clamping mechanisms 6 can be used to test multiple conveyor belts simultaneously.

[0024] As shown in Figures 1-3, the clamping plate 604 and the threaded rod 602 are movable hollow structures. A hydraulic rod 7 with a telescopic end connected to the bottom center of the clamping plate 604 is installed on the inner bottom center of the rectangular ring plate 601. The clamping plate 604 is raised and lowered by the hydraulic rod 7. The clamping plate 604 and the threaded rod 602 are not in contact. The height of the conveyor belt clamping and fixing can be adjusted by raising and lowering the clamping plate 604, which is convenient for the subsequent use of multiple sets of belt clamping mechanisms 6.

[0025] As shown in Figures 1-3, a drive device 8 for rotating a threaded rod 602 is installed at the rear end of the bottom inner side of the rectangular ring plate 601. A pulley 9 is connected to the top of the threaded rod 602. A transmission belt 10 is provided on the outer wall of the two sets of pulleys 9 to form a transmission structure. The rotation of the threaded rod 602 can be controlled by the drive device 8. The pulleys 9 and the transmission belt 10 can drive the rotation of the other set of threaded rods 602 synchronously, realizing the synchronous movement of the front and rear ends of the clamping plate 603 and avoiding the clamping plate 603 from shifting.

[0026] As shown in Figures 1-3, clamping plate 603 and clamping plate 604 can form a clamping structure with different heights. By raising and lowering clamping plate 603, the height of the conveyor belt can be controlled. Moreover, by using multiple sets of clamping plates 603 with different heights, multiple belt clamping mechanisms 6 can cooperate to clamp and fix longer conveyor belts. Furthermore, the tensile testing of conveyor belts of different lengths can be carried out simultaneously, saving time and improving work efficiency.

[0027] As shown in Figure 1-3, the external thread group 4 is configured as two sets of threads that are symmetrical about the center of the external thread group 4 and have opposite directions. By configuring the external thread group 4 as two sets of threads that are symmetrical about the center of the external thread group 4 and have opposite directions, the thread seats 5 set on the same set of external thread group 4 can move apart or towards each other. It can cooperate with the clamping mechanism 6 on another set of belt clamping mechanism 6 that moves in the opposite direction to test a longer conveyor belt.

[0028] Working principle: During use, controlling the rotation of the threaded rod 602 can drive the second clamping plate 604 to adjust its height, thereby controlling the distance between the second clamping plate 604 and the first clamping plate 603. This allows for clamping and fixing one end of conveyor belts of different thicknesses. Another set of clamping plates 604 and the first clamping plate 603 can clamp and fix the other end of the conveyor belt, thus securing it in place. Then, controlling the rotation of the adjusting rod 3 can cause the threaded seat 5 on the outer wall of the external thread assembly 4 to move outwards, thereby stretching and testing the conveyor belt at both ends. The multiple sets of belt clamping mechanisms 6 can simultaneously test multiple conveyor belts. The lifting and lowering of clamping plate 604 is controlled by hydraulic rod 7, and clamping plate 604 and threaded rod 602 are not in contact. The lifting and lowering of clamping plate 604 can adjust the height of the conveyor belt clamping and fixing, which is convenient for the subsequent use of multiple sets of belt clamping mechanisms 6. The lifting and lowering of clamping plate 603 can not only control the height of the conveyor belt clamping and fixing, but also, by having multiple sets of clamping plates 603 with different heights, multiple belt clamping mechanisms 6 can cooperate to clamp and fix longer conveyor belts. Moreover, the tensile testing of conveyor belts of different lengths can be carried out simultaneously, saving time and improving work efficiency.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
