Description
Technical Field
[0001] This utility model relates to the technical field of steel wire testing tools, and in particular to a synchronous testing device for steel wire ropes. Background Technology
[0002] In the field of wire rope strength testing, synchronous wire rope testing devices are crucial equipment for ensuring the safety of wire rope use. Their performance directly affects testing efficiency and result accuracy. However, existing wire rope testing devices still suffer from numerous technical challenges in practical applications, making it difficult to meet diverse testing needs and high-efficiency operation requirements. Specific problems include: The testing components of existing devices are mostly fixed installation structures, resulting in poor flexibility in adjusting the testing position. They cannot quickly adjust the testing points according to different diameters and applications of wire ropes. Furthermore, the locking mechanism after adjustment lacks stability and is prone to loosening during testing, leading to testing point displacement and affecting the consistency and reliability of the testing data. This makes it difficult to adapt to the testing needs of multi-specification wire ropes. Additionally, the device's support structure suffers from slippage issues. Moving parts typically employ a fixed spacing design, or while adjustable, they lack a reliable positioning mechanism. When inspecting wire ropes of varying lengths, the spacing of the sliding parts cannot be flexibly adjusted according to the actual length of the wire rope, resulting in a limited inspection range. Even if adjustments are made, the sliding parts are prone to shifting during inspection due to a lack of effective locking, damaging the inspection benchmark and affecting the accuracy of the results. Most existing inspection devices only support the inspection of a single wire rope one by one, lacking a structural design for simultaneous inspection of multiple wire ropes. When inspecting large batches of wire ropes, frequent replacement of the wire ropes to be inspected is necessary, resulting in long inspection cycles and low operational efficiency, failing to meet the needs of rapid quality screening of wire ropes in industrial production. Therefore, these problems need to be addressed. Utility Model Content

[0017] Working principle: When using this utility model, the installed equipment is placed on the designed base surface through the support platform 1. Then, the operator tightens or loosens the positioning plate 17 by rotating the bolts 16 installed on the mounting plate 15 to fix the sliding block 2 in the corresponding first sliding groove and second sliding groove. Then, the operator slightly lifts the detection rod 20 and adjusts the direction of the detection rod 20 in conjunction with the positioning sleeve 19 fixed by the mounting platform 8 and the first rubber strip 9. After the adjustment is completed, the steel wire passes through the electromagnetic detection body 10 installed at the lower end of the detection rod 20, passes through the laser diameter measuring device 12 fixed by the support rod 11, and then passes out from the electromagnetic detection body 10 installed at the upper end of the detection rod 20. Then, it is connected to the external traction device to power on the equipment. After the equipment is powered on, the first stepper motor 4 is started. The first stepper motor 4 will drive the moving block 6 forward through the drive screw 5. Since the moving block 6 is hinged to the rotating plate 7 and the rotating plate 7 is fixed to the mounting platform 8, the movement of the moving block 6 will drive the mounting platform 8 to move. Since different mounting platforms 8 move to different positions according to process requirements, the second stepper motor 23 installed in the second drive cover 18 is then started. The second stepper motor 23 will drive the limit rod 21 to rotate. Since the limit rod 21 is rotatably connected to the moving block 6 and fixed to the second gear 22, the first gear 24 and the ratchet 25, the rotation of the limit rod 21 will drive the second gear 22 and the first gear 24 located in the first drive cover 14 to rotate, thereby driving the toothed block in the rotating groove 13 to rotate. The movement then drives the rotating plate 7 to rotate. During the rotation of the limiting rod 21, the ratchet 25 will also rotate and strike the pawl 27. During the rotation of the ratchet 25, the pawl 27 is limited by the rotating rod 26 and the sliding rod 30 and rotates slightly with the ratchet 25. Then it is reset by the double-headed spring 29 installed on the positioning rod 28 and the sliding rod 30 to prevent the ratchet 25 from rotating in the opposite direction and forming a one-way self-locking structure. However, after each mounting platform 8 reaches the predetermined angle, the second stepper motor 23 can be turned off. Then, the winding strength and diameter of the steel wire are detected by external equipment in conjunction with the electromagnetic detector 10 and the laser diameter gauge 12. After the detection is completed, the operator pushes the sliding rod 30 with an external tool to make the pawl 27 and the ratchet 25 misaligned. The ratchet 25 can then reset by its own inertia.
[0018] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
