Travelling crane anti-reverse device, travelling crane, gantry type frame and electroplating production line

Abstract

The invention relates to the technical field of motor control, in particular to a travelling crane anti-reverse device, a travelling crane, a gantry type frame and an electroplating production line. The travelling crane anti-reverse device comprises a bracket, a travel switch and a control unit. The bracket is arranged on a frame. The travel switch comprises a switch body and a ball, the switch body is installed on the bracket, and the ball can abut against a hanging belt. When a motor rotates reversely in the rotating process, the hanging belt is separated from the ball, and the travel switch is triggered to generate an electric signal. After a control unit receives the electric signal, the motor is controlled to stop, the motor is prevented from rotating reversely, and smooth electroplating operation is guaranteed. Meanwhile, workpieces can be prevented from freely falling off, the workpieces are effectively protected, and the safety of the workpieces and electroplating operation is improved.

Description

technical field [0001] The invention belongs to the technical field of motor control, and in particular relates to a driving anti-reverse device, driving, a gantry frame and an electroplating production line. Background technique [0002] In the electroplating production line, the crane moves along the production line, and the hoisted workpieces enter the aqueduct one by one to complete the electroplating operation. [0003] Such as figure 1 and figure 2 As shown, the first rotating shaft 20 , the output shaft 10 of the motor, the second rotating shaft 30 and the sling 40 are arranged at intervals on the vehicle frame 100 . Wherein, one end of a sling 40 is wound around the output shaft 10 of the motor, and the other end is wound around the first rotating shaft 20 and extends vertically downwards, and the workpiece is hoisted thereon. One end of another sling 40 is wound around the output shaft 10 of the motor, and the other end is wound around the second rotating shaft ...

AI Technical Summary

Problems solved by technology

When the motor reverses, the suspenders 40 between the first rotating shaft 20 and the output shaft 10 and between the output shaft 10 and the second rotating shaft 30 will instantly loosen or deform, which will affect the normal electroplating operation

When the sling 40 is unwinding, the reversing time is too long, which may even cause the workpiece to fall and cause the workpiece to be scrapped
