Description

Technical Field

[0001] This utility model relates to the field of wire rope tension testing technology, specifically to a wire rope tension testing device with adjustable diameter. Background Technology

[0002] The cable force of a multi-functional wire rope tension meter is a crucial parameter for cable structures. During construction, cable force control is a vital factor affecting the internal forces and structural state of the entire structure. The magnitude of the cable force during the service phase has a significant impact on the lifespan of the structure. Currently, the cable force measurement methods commonly used in China can only measure the cable force during the tensioning stage. The magnitude of the cable force after tensioning is completed cannot be measured. During construction, if one steel cable is tensioned to the design value according to the design requirements, tensioning other steel cables will inevitably change the cable force of the first-tensioned cable, which may damage the entire structure or even cause catastrophic accidents.

[0003] Existing patents, such as the steel wire rope tension tester for elevator maintenance (application number 202121237757.4), include a tension tester body. A handle is fixedly connected to the left end of the tension tester body, and a display is provided at the front end of the tension tester body. An auxiliary positioning plate is rotatably connected to the outer side of the tension tester body, and a rotating shaft is fixedly connected to the outer side of the auxiliary positioning plate. In this utility model, the auxiliary positioning plate, positioning rod, insert plate, and limiting wheel are configured to coordinate the rotatable connection between the auxiliary positioning plate and the positioning rod, the fixed connection between the insert plate and the spring, and the fixed connection between the limiting wheel and the positioning rod.

[0004] A steel wire rope tension tester for elevator maintenance, with application number CN202221307263.3, belongs to the field of tension testers. It includes a tension testing arm, with a support device located in the lower area of ​​the arm. This utility model discloses a steel wire rope tension tester for elevator maintenance. Through the support device, the inner lifting tube moves up and down within the lifting sleeve, adjusting the height of the tension testing arm and providing auxiliary support during the tester's adjustment. This eliminates the need for manual operation during the adjustment process.

[0005] While the two patents mentioned above eliminate the need for manual operation, making the tension tester more flexible during debugging and adaptable to different application scenarios, they cannot limit the movement of the wire rope and are time-consuming and laborious when rotating the push handwheel or lever.

[0025] The present invention will now be described in further detail in conjunction with the full text.

[0026] Combined with appendix Figures 1-4 An adjustable diameter wire rope tension testing device includes a tension tester body 1, an auxiliary positioning wheel 2 rotatably connected to the outer side of the tension tester body 1, a force application clamp 3 fixedly connected to the middle of one side of the tension tester body 1, a display 6 provided at the front end of the tension tester body 1, a limiting device 4 movably installed on the force application clamp 3 to restrict the wire rope, and a driving device 5 installed on the force application clamp 3 to push the limiting device 4 to move.

[0027] In specific implementation of this utility model, such as Figure 1 and Figure 2 As shown. A limiting device 4 for restricting the steel wire rope is movably installed on the force-applying clamp 3. The limiting device 4 includes a movable block 401 slidably connected to the force-applying clamp 3. A guide block 402 is mirror-mounted on the side of the movable block 401 near the tension tester body 1. A first groove 403 is formed on the opposite surface of the two guide blocks 402. A slidable clamping block 404 is installed in the first groove 403. An adjusting spring 405 is installed between the clamping block 404 and the first groove 403. Specifically, the steel wire rope is placed between the two clamping blocks 404 on the movable block 401. The two clamping blocks 404 restrict the steel wire rope by adjusting the spring 405, which can prevent the steel wire rope from shaking during the test, thus reducing the positioning effect of the tension tester and causing inaccurate test results. Furthermore, by adjusting the spring 405, it can be adapted to test steel wire ropes of different diameters.

[0028] A slider 406 is installed at the lower end of the moving block 401. A sliding hole 407 is opened on the force-applying clamp 3 to cooperate with the slider 406. A reset spring 7 for resetting is directly installed on the slider 406 and the sliding hole 407. The slider 406 moves in the sliding hole 407, and the sliding hole 407 can limit the position of the slider 406. The reset spring 7 adjusts automatically.

[0029] In specific implementation of this utility model, such as Figure 1As shown, the drive device 5 includes fixed blocks 501 that are disposed opposite to the force-applying clamping plate 3. Threaded rods 502 are threadedly installed on the two fixed blocks 501. A stop plate 503 is installed at the end of the threaded rod 502 near the moving block 401, and a turntable 504 is installed at the end of the threaded rod 502 away from the moving block 401. The threaded rod 502 rotates and moves within the threaded hole of the fixed block 501, causing the stop plate 503 to move closer to the moving block 401 and pushing the moving block 401 to move. During testing, the threaded hole and the threaded rod 502 can be lubricated with lubricating oil.

[0030] Specifically, the two fixing blocks 501 can lock the threaded rod 502 in the reverse direction. The threaded rod 502 has a self-locking function and can be axially locked by the two fixing blocks 501.

[0031] In specific implementation of this utility model, such as Figure 1 , Figure 3 and Figure 4 As shown, multiple sets of force-saving devices 8 are installed on the outer side of the turntable 504. The force-saving device 8 includes a fixed rod 801 connected to the outer side of the turntable 504. A force-saving tube 802 is fitted on the outer side of the fixed rod 801. A limiting rod 803 is installed inside the force-saving tube 802 and can move within the fixed rod 801. A moving groove 804 is opened in the fixed rod 801 to cooperate with the movement of the limiting rod 803. The force-saving tube 802 can move on the outer side of the fixed rod 801, and the limiting rod 803 can move within the moving groove 804 of the limiting rod 803. Moving the force-saving tube 802 increases the lever arm of the force, which can perform force-saving rotation. Furthermore, the limiting rod 803 has a T-shaped structure, and the force-saving tube 802 cannot be completely pulled out through the limiting rod 803, thus playing a limiting role. Example

[0032] like Figure 1 As shown, the operator takes out the tension measuring instrument body 1 and moves it to the wire rope positioning area. The wire rope is then positioned between the tension measuring instrument body 1 and the limiting device 4. The wire rope is placed between the two clamping blocks 404 on the moving block 401. The two clamping blocks 404 restrict the wire rope through the adjusting spring 405, which can prevent the wire rope from shaking during the test. The threaded rod 502 rotates and moves in the threaded hole of the fixed block 501, which drives the abutment 503 to approach the moving block 401 and pushes the moving block 401 to move, gradually clamping the wire rope, thus completing the test. Example

[0033] like Figure 4As shown, this embodiment adds a labor-saving device 8 compared to embodiment one. The operator takes out the tension measuring instrument body 1 and moves it to the wire rope positioning area. The wire rope is positioned between the tension measuring instrument body 1 and the limiting device 4. The wire rope is placed between the two clamping blocks 404 on the moving block 401. The two clamping blocks 404 restrict the wire rope by adjusting the spring 405, which can prevent the wire rope from shaking during the test. The labor-saving tube 802 can move outside the fixed rod 801, and the limiting rod 803 can move in the moving groove 804 of the limiting rod 803. Moving the labor-saving tube 802 increases the lever arm of the force, which can perform labor-saving rotation. The threaded rod 502 rotates and moves in the threaded hole of the fixed block 501, which drives the abutment 503 to approach the moving block 401 and pushes the moving block 401 to move, gradually clamping the wire rope, thereby completing the test.

[0034] The present invention and its embodiments have been described above. This description is not restrictive, and the embodiments shown throughout the text are only one of the embodiments of the present invention. The actual structure is not limited to this. In conclusion, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit of the present invention, such design should fall within the protection scope of the present invention.
