Chain lifting safety protection device for mechanical three-dimensional parking garage

Abstract

The invention discloses a chain lifting safety protection device for a mechanical three-dimensional parking garage. The chain lifting safety protection device comprises a driving main shaft assembly,a driven shaft assembly, a counterweight assembly, a counterweight guide rail assembly, a lifting chain and a safety protection rope. Lifting chain wheel assemblies are arranged at the two ends of thedriving main shaft assembly, and the lifting chain and the safety protection rope are wound around the lifting chain wheel assemblies side by side. The lifting chain and the safety protection rope enter the input end of the driven shaft assembly from the output end of the driving main shaft assembly, one end of the lifting chain and one end of the safety protection rope are fixed to a lifting caror a lifting comb tooth frame, the other end of the lifting chain and the other end of the safety protection rope are fixed to the counterweight assembly, and the lifting action of the lifting car orthe lifting comb tooth frame is achieved through rotation of the driving main shaft assembly. According to the device, the safety coefficient of chain lifting is greatly increased, the danger causedby chain breakage and falling of the whole parking garage is avoided, and the device is simple, compact and reliable in structure and suitable for popularization.

Description

technical field [0001] The invention belongs to the field of mechanical three-dimensional parking garages, and more specifically relates to a chain lifting safety protection device for mechanical three-dimensional parking garages. Background technique [0002] Lifting and traversing three-dimensional garages account for more than 80%. The lifting methods mainly include chain lifting, wire rope lifting, hydraulic lifting and screw lifting, among which the chain and wire rope are the most common. [0003] The chain-lifted garage has good stability during the lifting process. The structure of the chain and the wire rope are different. The platform lifted by the chain can only shake in the front and rear directions, while the platform lifted by the wire rope shakes in all directions. [0004] The steel wire rope will elongate, deform or even knot under the impact of operation, which will affect the accuracy of lifting operation. When it is used frequently, it is more likely to ...

AI Technical Summary

Problems solved by technology

[0004] The steel wire rope will elongate, deform or even knot under the impact of operation, which will affect the accuracy of lifting operation. When it is used frequently, it is more likely to break under the impact, which reduces the safety and reliability of the equipment; It is not easy to be found, and it needs to be replaced once every six months when it is used frequently, and the service life is low

[0005] Although chain hoisting is more reliable than wire rope hoisting, there are still risks such as breakage when used in a three-dimensional parking garage, which will cause the chain hoisting car or hoisting comb frame to drop to the bottom, resulting in a falling phenomenon, which has many problems. big security risk
