[0021] The present utility model provides a multi-dimensional wear test device as shown in Figure 1 - Figure 2 The device includes a workbench 1. A first fixing frame 3 is fixed on one side of the workbench 1. A second fixing frame 4 is arranged on one side of the first fixing frame 3. A pulley 5 and an adjustment disk 6 are respectively rotatably connected to the same side of the first fixing frame 3 and the second fixing frame 4. A connecting rope is drivingly arranged on the pulley 5. A bottom plate 12 is fixed at the bottom end of one side of the workbench 1 in the short side direction. A buffer member 13 is fixed at the top of the bottom plate 12. A counterweight box 9 is fixed at the top of the buffer member 13. Two ends of the connecting rope are respectively connected to the counterweight box 9 and the adjustment disk 6. The position of the connecting rope between the counterweight box 9 and the adjustment disk 6 can be supported by the pulley 5, so that the connecting rope has a certain length for wear test.

[0022] In the present utility model, the connecting rope is made of ultra-high molecular weight polyethylene split film fiber to make the rope.

[0023] A chute 11 is opened on one side of the workbench 1 close to the counterweight box 9. A slider is fixed on one side of the counterweight box 9. The slider is slidably matched inside the chute 11. The chute 11 can increase the stability of the counterweight box 9 rising or falling.

[0024] A connecting ear 10 is fixed at the top of the counterweight box 9. One end of the connecting rope is connected to the connecting ear 10. One end of the connecting rope can be wound and knotted on the connecting ear 10 to complete the fixation of one end of the connecting rope.

[0026] In the actual operation of the present utility model, when both ends of the connecting rope are connected and fixed, the driving motor can be started to drive the adjustment disk 6 to rotate. While the adjustment disk 6 rotates, the counterweight box 9 can be driven to rise. By increasing or decreasing the number of counterweight blocks inside the counterweight box 9, the adaptability of the connecting rope under different tensile forces can be tested.

[0027] Furthermore, as the adjustment disk 6 drives the connecting rope to rotate, while the counterweight box 9 rises, it will pull the buffer member 13 to extend.
