A self-opening body hanger

Abstract

The invention discloses a car body lifting appliance capable of being automatically opened. The car body lifting appliance capable of being automatically opened comprises a lifting frame, a chain wheel mechanism and lifting arms symmetrically arranged at the left side and the right side of the lifting frame, wherein the chain wheel mechanism is fixedly arranged at the middle part of the lifting frame; limit clamping block bases, press-off arm bases and cam bases are symmetrically and fixedly arranged on the lifting frame, and between the two sides of the chain wheel mechanism and the two endsof the lifting frame in sequence; a press-off arm is arranged on each press-off arm base, the low end of each press-off arm is hinged to the corresponding press-off arm base, a limit rod is arranged at one side of each press-off arm, the other end of the limit rod is slidably connected with the corresponding limit clamping block base, and a cam control rod is arranged at the other side of each press-off arm; and a cam is arranged on each cam base, the low end of each cam is fixedly connected with the top end of the corresponding lifting arm, and the other end of the cam is hinged to the corresponding cam control rod. The car body lifting appliance capable of being automatically opened is simple in structure, and capable of being transformed on the basis of the existing car body lifting appliance; and moreover, the opening-closing reliability of the car body lifting appliance is ensured, the energy consumption is reduced, the use cost is lowered, and the economic expense is saved.

Description

technical field [0001] The invention relates to a hoisting device, in particular to an automatically opened vehicle body hoist. Background technique [0002] At present, in the production process of automobiles, it is often necessary to lift the whole vehicle to different process parts on the production line by means of a spreader, or lift it to other equipment for processing or to install other components. During the use of the spreader, the boom is usually electrically driven to realize the electronically controlled opening and returning of the boom; however, the electric drive of the boom increases the complexity of the operation on the one hand, and the overall professional requirements for the operator Higher; on the other hand, it needs to consume electric energy, increase operating costs, and cause economic losses. Contents of the invention [0003] In order to overcome the defects of the prior art, the purpose of the present invention is to provide an automatic op...
