Preferably, rubber pads are arranged on the opposite surfaces of the first flange and the second flange, nuts are arranged at two ends of the stud, and the distance between the nuts at two ends of the stud is larger than the sum of the thicknesses of the first flange and the second flange.
Preferably, a guide sleeve is embedded in the positioning hole groove, and the top end of the guide sleeve is of a horn mouth structure.
Preferably, a proximity switch for monitoring the position of the pin shaft is arranged below the box body.
When the movable hoist trolley reaches the working position, the pin shaft is rotated by the hand wheel to descend by utilizing the threaded connection structure of the pin shaft and the positioning sleeve. The inner diameter of the first through hole of the first flange is larger than the outer diameter of the stud, the distance between the nuts at the two ends of the stud is larger than the sum of the thicknesses of the first flange and the second flange, and a movable connection mode of the movable pin head and the pin shaft is formed, so that the movable pin head can deviate from the pin shaft to move. The movable pin head is similar to a structure suspended below a pin shaft, and when the positions of the positioning pin and the positioning hole groove are slightly deviated, the smooth dome structure at the lower end of the movable pin head is guided by the horn mouth structure at the top end of the guide sleeve to be smoothly inserted into the positioning hole groove. And then the first flange and the second flange are completely attached, and the positioning of the movable hoist trolley is realized by utilizing the static friction force of the rubber pad and the limit relation between the stud bolts and the first through holes on the first flange.
