Silo roof truss platform lowering system and its control method

Abstract

The invention discloses a cylindrical silo top truss platform descending system and a control method of the cylindrical silo top truss platform descending system, wherein the descending system comprises electric chain hoists and a controller for controlling the synchronous linkage or independent transferring of each electric chain hoist, wherein the tail end of a chain of each electric chain hoist passes through a cylindrical silo top to be connected with the peripheral edge of a truss platform; a space measuring device is arranged in the top center of the truss platform; and a laser emitter is arranged in the bottom center of the cylindrical silo top. The synchronous linkage or independent transferring of each electric chain hoist is realized through the controller; meanwhile, relevant measuring parameters such as inclination directions, inclination angles and deviation distance in the truss platform descending process are monitored in real time through the space measuring device and the laser emitter which mutually correspond to each other; and the local fine adjustment can be carried out during the integral synchronous descending of the truss platform is ensured, so the safe, stable and fast descending of the truss platform can be realized, and the descending dismounting construction problem of the truss platform is thoroughly solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a silo roof truss platform lowering system and a control method thereof. Background technique [0002] A silo is a vertical container for storing loose solids such as grain, feed, coal, cement and ore. It has the characteristics of saving storage space, facilitating the implementation of loading and unloading mechanization and automation, reducing material loss and reducing dust pollution to the environment. It is widely used In the industrial and agricultural production and storage and transportation sectors. Among them, the reinforced concrete circular silo is currently the most widely used large-capacity silo type. According to the height-to-diameter ratio (the ratio of the grain storage height to the inner diameter of the silo), it is a deep silo (or vertical silo) when it is greater than or equal to 1.5, and it is less than 1.5. At that time, it was shallow wa...

Problems solved by technology

[0006] During the descending process of the truss platform, once the descent is out of sync, the force on each lifting point will also change, causing the entire truss platform to tilt and deviate; due to the limited gap between the truss platform and the inner wall of the warehouse, the tilted and deviated truss platform It may collide with the inner wall of the warehouse and scratch the inner wall of the warehouse. In severe cases, accidents such as truss tipping may even occur
