A pneumatic balance crane cylinder mechanism

Abstract

The invention relates to the field of balance crane equipment, and discloses a pneumatic balance crane cylinder mechanism, which includes a balance cylinder, a support side plate, a ball screw, a piston plate, and a cable reel, and both sides of the balance cylinder are provided with support side plates , a ball screw is arranged between the two supporting side plates, and a piston plate and a cable reel are arranged on the ball screw. The pneumatic balance crane cylinder mechanism, through the design of the supporting side plates on both sides of the cable drum, cooperates with the sealing plate, the first sealing plate, the second sealing plate, the first fixed shaft, the second fixed shaft, the moving sealing plate and the sealing When the balance crane moves upwards with no load, a negative pressure is formed between the first sealing plate and the piston plate on the right side of the cable drum, and the negative pressure increases as the cable drum continues to move, and the limit line The leftward movement of the cable drum makes the balance crane gradually tend to a stable state when it moves up with no load, which makes the balance crane less impacted and improves the service life of the balance crane.

Description

technical field [0001] The invention relates to the field of balance crane equipment, in particular to a pneumatic balance crane cylinder mechanism. Background technique [0002] The pneumatic balance crane is a pneumatic handling device that uses the gravity of the heavy object and the pressure in the cylinder to achieve balance to lift or lower the heavy object. Generally, a pneumatic balance crane has two balance points, which are heavy load balance and no-load balance. The gripper will always be at rest. At this time, only a small external force can be used to lift or lower the heavy object or gripper, which improves work efficiency and reduces labor intensity of workers. The pneumatic balance crane includes inflatable equipment, reversing valves, and cylinder mechanisms. and other components. [0003] Existing cylinder mechanism comprises balance cylinder 1, support side plate 2, ball screw mandrel 3, piston plate 4 and cable reel 5, when working (refer to Figure 4 ):...

AI Technical Summary

Problems solved by technology

[0004] However, when the existing cylinder mechanism is working, when the steel wire rope for hanging the heavy object rises with no load, the speed will become faster and faster, resulting in excessive internal impact on the balance cylinder, which will easily cause damage to the balance crane and reduce the balance. The service life of the crane, and when the pressure is released on the mount, the pressure on the side of the piston plate 4 drops sharply, and the speed of the piston plate 4 and the reel 5 moving to the right is also getting faster and faster, which also causes an impact on the inside of the balance cylinder, making the balance crane reduced service life
