[0025] A plurality of supporting wheels 8 are also arranged below the main body 12 of the simulated-mine cable bending machine. A tension sensor is arranged on one side of the upper end of the supporting wheel for feeding back the change of tension during the cable bending process.

[0027] This embodiment is preferred, referring to Figure 7 The clamping device 3 includes a clamping plate 31, one side of which is connected to a hydraulic cylinder, and the cable is compressed and fixed by the hydraulic cylinder.

[0028] Preferably, in this embodiment, the main body 12 of the simulated-mine cable bending machine is provided with a plurality of mounting holes 121 on one side of the guide wheel C10, which are used to adjust the mounting position of the guide wheel C10 to realize tests under different bending states.

[0029] This equipment consists of two parts: a cable bending machine and a cable retracting machine. It simulates the bending state of the cable during long-distance use in mines with different bending radii and different tensions, and bends it repeatedly.

[0030] Working principle:

[0031] Test process: First, pass one end of the cable from bottom to top through the two guide wheels C of the base of the simulated mine cable bending test machine, then continue to pass through the two guide wheels B of the mobile slide from bottom to top, then bypass the upper guide wheel A of the equipment, and place it horizontally on the cable bracket, then adjust the manual hydraulic pump reversing valve to make the hydraulic oil push the hydraulic cylinder piston rod to extend, so that the clamping device presses the cable tightly on the cable bracket; then wrap the other end of the cable around the winch reel 4 times, and then fix the end of the cable with a pressure plate. When the mobile slide moves from the middle to the left and right, the winch will also retract and release the cable synchronously to ensure stable tension. The cable follows the mobile slide to bend and relax.

[0032] Electrical function: Weak current is loaded at both ends of the cable. When the cable is broken or short-circuited, the power is automatically cut off and the equipment stops. At the same time, the equipment is equipped with a sensor. When it stops, the number of bending times of the cable test will be displayed on the control cabinet panel, and the test is over.

[0033] The device can simulate cables in mines and accurately measure the number of bends before breaking of different cables at different bending radii and tension conditions. This can further explore the relationship between pitch, bending radius and tension value, so that cable manufacturers can effectively control the bending performance of products to improve product quality.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent substitution or improvement made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
