[0025] Please refer to Figure 1 , 2 and 4, a winch cable tension stability adjustment mechanism, comprising: a nut seat 13, which is installed below the support column 6, inside which a transmission screw rod 15 is installed, and at one end of the transmission screw rod 15, a driving motor 14 is connected; a rotating structure is formed between the driving motor 14 and the transmission screw rod 15, and the transmission screw rod 15 penetrates through the inside of the nut seat 13, and the nut seat 13 is fixedly connected to the support column 6; the driving motor 14 can drive the transmission screw rod 15 to rotate, and the rotating transmission screw rod 15 can horizontally move the nut seat 13, the support column 6 and the positioning wheel 9, so as to adjust the limiting position of the cable.

[0026] Working principle: When using the cable tension stable adjustment mechanism of this winch, first pass one end of the cable through between the clamping runners 5 and then above the positioning runner 9 until it is installed at the designated position. Start the bidirectional hydraulic rod 16, and the bidirectional hydraulic rod 16 drives the moving seat 3 to move horizontally relative to each other, so as to adjust the relative positions of the clamping runners 5, which is convenient for the installation and clamping of the cable.

At the same time, start the lifting hydraulic cylinder 12, and the lifting hydraulic cylinder 12 drives the lifting slider 10 to move down until the other end of the cable can be clamped and positioned by the positioning runner 9 and the lifting slider 10. Then, adjust the limiting position of the cable as needed. Start the driving motor 14, and the driving motor 14 drives the transmission lead screw 15 to rotate. The rotating transmission lead screw 15 can move the nut seat 13, the support column 6 and the positioning runner 9 horizontally until the positioning runner 9 is moved to a suitable position below the lifting slider 10. Finally, when the cable tension needs to be adjusted, the hydraulic push rod 8 can be used to drive the lifting column 7 and the positioning runner 9 to move down, and at the same time, the lifting hydraulic cylinder 12 drives the lifting slider 10 to move down to clamp the cable. At this time, the cable becomes loose and moves in the reverse direction, so that the cable becomes tight. At the same time, during the adjustment process, the cable is inside the limiting structure and will not break away. This is the working principle of the cable tension stable adjustment mechanism of this winch.
