Description

A portable platform for combined installation of coal hoppers

technical field

The utility model relates to a portable platform for combined installation of coal buckets.

Background technique

In the late 1980s, foreign designed and imported unit projects adopted an all-steel structure main workshop, and coal scuttles also adopted steel structures. Steel coal scuttle is widely used because of its light weight, less steel per unit volume, reasonable and clear force, and can give full play to the tensile properties of steel.

In thermal power plants and large heating plants, steel coal hoppers are mostly silo structures. And as the capacity of the unit continues to increase, the volume and height of the steel coal scuttle continue to increase, and the height of the scaffold also increases continuously during the installation of the coal scuttle.

Existing construction techniques all use large-area full-scale scaffolding inside and outside before construction, and construction workers perform related work such as combining coal hoppers and welding on the scaffolding. After the coal hopper assembly is installed, all the scaffolding will be removed. The whole construction technology not only has slow progress, long time, high labor cost, heavy disassembly workload after construction is completed, but also leases or purchases a large number of turnover materials such as pipes and buckles. Moreover, the height of the scaffolding is relatively high, and there is a great potential safety hazard during the disassembly process.
