Lifting object stage controlled by pulleys in building machinery

Abstract

The invention discloses a lifting object stage controlled by pulleys in building machinery. The lifting object stage controlled by the pulleys in the building machinery comprises a base, fixed framesare connected to the left and right sides above the base, bearing housings are connected to the left and right sides above the base, bearings are installed in the bearing housings, rotating rods are connected into the bearings, the left sides of the rotating rods are connected with motors, and motor supports are connected under the motors; the inner walls of the right sides of the upper ends of the fixed frames are connected with first pulleys, the middle portions of the rotating rods are connected with first steel wire ropes in a contacting mode, the other ends of the first steel wire ropes are connected with a hook, second steel wire ropes are connected under the hook in a contacting mode, the other ends of the second steel wire ropes are connected with the object stage, the left and right sides of the object stage are connected with connecting rods, the other ends of the connecting rods are connected with sliding blocks, and the interiors of the middles the sliding blocks are connected with sliding rods in a contacting mode; and the pulley control for the building machinery lifting object stage presents an axisymmetric connection mode. The lifting object stage controlled by thepulleys in the building machinery is very stable for controlling the object stage in the process of lifting, own safety of an operator is ensured, and the safety performance is high.

Description

technical field [0001] The invention relates to the field of construction machinery equipment, in particular to a pulley control used for lifting and lowering a loading platform of construction machinery. Background technique [0002] Construction machinery is the general term for machinery and equipment used in engineering construction and urban and rural construction. It is also called "construction machinery" and "construction machinery" in China. According to Chinese standards, construction machinery is divided into the following types: excavation machinery, shovel Transportation machinery, compaction machinery, engineering hoisting machinery, road machinery, concrete machinery, decoration machinery, high-altitude operation machinery, concrete product machinery, piling machinery, etc. The lifting stage is an important part of construction machinery. It is very commonly used in building construction, and it is usually used to hoist building materials or construction equip...

AI Technical Summary

Problems solved by technology

[0003] However, the existing construction machinery lifting platform has a complex structure, and it is very dangerous for the operator to operate. The lifting platform is very unstable when transporting goods, which seriously threatens people's own safety, and the safety performance is very low.
