Swing bar chain fall protection device

Abstract

The invention discloses a swing rod chain vehicle falling protection device. The swing rod chain vehicle falling protection device is structurally composed of steel wire ropes, steel wire rope fixing units, guiding pulleys, guiding brackets and heavy punch transmission units. Vehicle falling transmission protection devices composed of the steel wire ropes, the steel wire rope fixing units, the guiding pulleys, the guiding brackets and the heavy punch transmission units are mounted in all pretreatment / electrophoresis process tanks. The steel wire rope fixing units, the guiding pulleys and the guiding brackets are fixed in all the process tanks. The heavy punch transmission units are arranged outside the tanks. One ends of the steel wire ropes are fixed through the steel wire rope fixing units, and the other ends of the steel wire ropes pass through the guiding pulleys and the guiding brackets and are routed in the vehicle body moving path direction and then are led out to be connected to counterweight frames of the heavy punch transmission units. Two sets of the whole swing rod chain vehicle falling protection devices are arranged in all the tanks left and right in the width direction of vehicle bodies. When a workpiece falls from a swing rod, the workpiece makes contact with the steel wire ropes and drags the steel wire ropes to move downwards, and heavy punches are forced to transmit, so that shutdown protection is conducted. The swing rod chain vehicle falling protection device has the characteristics of being simple in structure, safe, reliable, convenient to use, mount and maintain and capable of conducting vehicle falling protection on pretreatment room equipment, electrophoresis room equipment and swing rod chains.

Description

technical field [0001] The invention belongs to the field of mechanized transportation in automobile painting workshops, and in particular relates to a car crash protection device for pretreatment / electrophoresis swing bar chains. Background technique [0002] In the mechanized conveying system of pretreatment / electrophoresis in the painting workshop, the pendulum chain is able to enter and exit each pretreatment and electrophoresis process tank at a large angle of 45°, which is very helpful for eliminating air bubbles on the roof after entering the tank and exiting the tank It has a good draining effect on the body after liquid, and can shorten the workshop area occupied by the equipment, so it is widely used in the body painting workshop. After the swing rod chain brings the body into the tank, it will be affected by the buoyancy of the tank liquid on the body and the impact force of the tank liquid during the movement, which will cause the body to float. Seat support, un...

AI Technical Summary

Problems solved by technology

After the swing rod chain brings the body into the tank, it will be affected by the buoyancy of the tank liquid on the body and the impact force of the tank liquid during the movement, which will cause the body to float. Seat support, under the action of the tank liquid, the car will fall into the tank. If the swing link chain does not stop in time after the crash, the rear swing bar and the body will hit the falling body, resulting in damage to the process tank. The internal pipeline, in severe cases, will cause great damage to the tank structure, the chain of the pendulum chain, and the track
