When in use, the device is fixed on the external boom by installing the hinge seat 16, and the boom drives the device to move above the counterweight to be clamped, so that the frame 1 covers the counterweight, and the two sets of clamping plates 9 are located on both sides of the counterweight. Then the electric push rod 14 is started, and the telescopic end of the electric push rod 14 extends to drive the transmission cross bar 15 to move upward, and drives the positioning rod 13 to move upward in the positioning rod cavity 4. The positioning rod 13 drives the cam 11 to rotate around the rotating rod 10 through the connecting piece 12, and the cam 11 swings downward on the side close to the push plate 8. , push the push plate 8 to one side of the middle plate 6, the spring 19 is compressed, the push plate 8 pushes the clamping plate 9 out of the storage chamber 5 through the push rod 7 and then clamps it on the side wall of the counterweight. The two sets of clamping plates 9 clamp the counterweight and then move it to the specified position through the boom. Then the telescopic end of the electric push rod 14 is started in reverse to retract, the transmission cross bar 15 drives the positioning rod 13 to move downward, and the connecting piece 12 drives the cam 11 to rotate in the opposite direction. Due to the elastic force of the spring 19, the push plate 8 is pushed away from the middle plate 6, driving the clamping plate 9 to separate from the side wall of the counterweight and then stored in the storage chamber 5, which is convenient for the next clamping and for reciprocating batch clamping.
