[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0026] Please see Figure 1-5 This utility model provides a technical solution for a cable tensile testing device: A cable tensile testing device includes a workbench 1, two sets of worm gear screw jacks 2 are arranged parallel to each other at the top center of the workbench 1, a placement plate 3 is arranged on the two sets of worm gear screw jacks 2, a wheel-type sensor 4 is arranged at the top center of the placement plate 3, a lifting seat 5 is arranged on the wheel-type sensor 4, a lifting pulley 6 is arranged at the top of the lifting seat 5, and a support arm 7 is arranged at both ends of the workbench 1 located at the worm gear screw jacks 2.

[0027] In this embodiment, two sets of worm gear screw jacks 2 are provided to synchronously drive the placement plate 3 to rise and fall. A lifting pulley 6 is provided to lift the cable for tensile testing. A wheel-type sensor 4 is provided at the bottom of the lifting seat 5 to facilitate the detection of the pressure borne by the upper lifting pulley 6, thereby detecting the specific tensile force value of the cable. Two support arms 7 are symmetrically arranged to facilitate the straightening of the cable. The tensile test of the cable is carried out by the lifting action of the worm gear screw jack 2 in the middle. The operation is simple and convenient, which greatly improves the testing efficiency and data reliability.

[0028] Furthermore, the worm gear screw jack 2 includes: a worm gear seat 21, the bottom of which is fixedly connected to the top of the worktable 1, a screw 22 vertically mounted on the worm gear seat 21, and a worm 23 horizontally mounted on the worm gear seat 21, the worm 23 being connected to the screw 22 in a transmission manner.

[0029] In this embodiment, the worm gear screw jack 2 mainly consists of a worm gear seat 21 and a screw 22. The center of the worm gear seat 21 has an internal thread structure, which is equivalent to the nut of the screw 22 and matches the screw 22. The worm 23 is connected to the screw 22 in a transmission connection. When the worm 23 drives the worm gear to rotate, the worm gear will drive the screw 22 to move axially, thereby realizing the function of lifting or lowering. By installing the placement plate 3 on the screw 22, it is convenient to perform tensile testing on the cable during the lifting action of the screw 22.

[0030] Typically, the worm 23 on both sets of worm gear screw jacks 2 is designed as a single piece, and handwheels 9 are provided at both ends of the worm 23.

[0031] In this embodiment, two sets of worm gear screw jacks 2 are controlled by the same worm 23. The rotation of the worm 23 synchronously drives the screws 22 on the two sets of worm gear screw jacks 2 to rise and fall synchronously, ensuring the stable rise and fall of the placement plate 3 on the screw 22. By providing handwheels 9 at both ends of the worm 23, it is convenient for the operator to control the rise and fall of the worm gear screw jacks 2 from both sides of the device.

[0032] Specifically, a pressure sensing controller 10 is provided on one side of the wheel-type sensor 4 on the placement plate 3.

[0033] In this embodiment, the wheel spoke sensor 4 is electrically connected to the pressure sensor controller 10, so that the pressure sensor controller 10 can control the wheel spoke sensor 4 to operate and display the pressure value.

[0034] In addition, several sets of sliding columns 11 are provided around the bottom of the lifting seat 5, and a limit plate 12 is provided at the bottom of the sliding column 11.

[0035] In this embodiment, a lifting seat 5 is installed on the top of the wheel spoke sensor 4 to detect the pressure borne by the lifting seat 5. The lifting seat 5 is conveniently limited to move up and down by the sliding column 11. A limit plate 12 is provided at the bottom of the sliding column 11 to facilitate the determination of the initial position of the lifting seat 5 by the limit plate 12, thereby improving the accuracy of detection.

[0036] In addition, each of the two support arms 7 is equipped with a cable chuck 8.

[0037] In this embodiment, the cable is fixed by the cable chuck 8, so that both ends of the cable are kept horizontal and taut at both ends of the lifting pulley 6.

[0038] It should be noted that the workbench 1 is equipped with cabinet doors 13.

[0039] In this embodiment, the cabinet door 13 is provided to facilitate the storage of miscellaneous items.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
