At the same time, the wire rope is placed in the sliding track, and then the pushing cylinder drives the wire rope to move along the sliding track until the wire rope and the blocking member are against each other. At this time, the sensor can measure the relative distance of the pushing cylinder, thereby obtaining the length of the wire rope, and then the adjustment cylinder drives the position of the adjustment seat according to the wire rope length transmitted by the sensor, thereby changing the relative distance between the pushing cylinder and the wire rope, and then the blocking member is removed from the sliding track, and the pushing cylinder pushes part of the wire rope into the hardware, and finally rivets are performed to complete the fixation.

The vertical cylinder is arranged on the transverse seat and drives the vertical seat to move vertically. The locking cylinder is arranged on the vertical seat and drives the locking block to move. The locking block has the function of fixing the hardware on the vertical seat.

[0012] By adopting the above technical solution, when hardware needs to be loaded, the hardware is first placed in the vertical seat and fixed by the locking cylinder and the locking block, and then the longitudinal cylinder drives the longitudinal seat to move longitudinally, so that the longitudinal seat is close to the end of the sliding track, and then the transverse cylinder drives the transverse seat to move transversely, so that the transverse seat continues to approach the end of the sliding track, and finally the longitudinal cylinder drives the longitudinal seat to move vertically, so that the hardware on the longitudinal seat is opposite to the end of the sliding track, waiting for the insertion of the wire rope.
