Inspection door opening and closing mechanism

Abstract

The invention discloses an inspection door opening and closing mechanism. The inspection door opening and closing mechanism comprises a cross beam, a rotating assembly, a hoisting arm, a hoisting assembly and an inspection door; and the rotating assembly is arranged on the cross beam, the hoisting arm is L-shaped, the upper end of the hoisting arm is a vertical part, the lower end of the hoistingarm is a horizontal part, the upper end of the hoisting arm is rotatably matched with the rotating assembly, the hoisting assembly is arranged at the lower end of the hoisting arm, and the inspectiondoor is matched with the hoisting assembly. According to the scheme, a fixed hoisting rotary structure is adopted, bearing of the weight of the inspection door is guaranteed through the bearing crossbeam and the rotating assembly, and meanwhile the rotating flexibility after bearing can be guaranteed; a sliding type pin shaft structure can be adopted at the joint of the inspection door opening and closing mechanism and the inspection door, displacement is carried out along with opening of the inspection door, and the function of pulling out the inspection door while rotating is achieved; andworkload and time for opening and closing are greatly reduced, and frequent observation and maintenance on site are facilitated.

Description

technical field [0001] The invention relates to an inspection door opening and closing mechanism. Background technique [0002] There is no convenient opening device for the inspection door of the material silo of the sludge. Every time it is opened for observation and maintenance, it needs to be fixed with a lifting hoist and then connected to the inspection door. Since the inspection door of the silo is heavy and cooperates with the material silo The clearance is small, the lifting hoist cannot meet the precision work, and the silo inspection door needs to be opened frequently, and the workload of preparation, closing after inspection and cleaning is heavy every time it is opened. Contents of the invention [0003] The object of the present invention is to provide an inspection door opening and closing mechanism in order to overcome the deficiencies of the prior art. [0004] In order to achieve the above purpose, the technical solution adopted by the present invention ...
