Boiler furnace maintenance platform and rail support thereof

Abstract

The invention discloses a boiler furnace maintenance platform and a rail support thereof. The rail support comprises a rail base clamping plate and a rail connection pipe; the rail base clamping plate is provided with a rail base slideway which is matched with an I-shaped beam flange; bolt holes are formed in the rail base slideway; the rail base clamping plate is arranged on an I-shaped beam by arranging connection bolts in the bolt holes in a matched manner; a rail base clamping and connecting plate is arranged in the middle part of the rear part of the rail base slideway of the rail base clamping plate; inner pipe wall clamping grooves which are matched with the rail base clamping and connecting plate are formed in the inner wall of the rail connection pipe; outer pipe wall clamping grooves with an antiskid function are formed in the outer pipe wall of the rail connection pipe; and the rail connection pipe is arranged on the rear surface of the rail base slideway through the match of the inner pipe wall clamping grooves and the rail base clamping and connecting plate. Therefore, through the rail support disclosed by the invention, rails can be arranged on a platform body.

Description

technical field [0001] The invention relates to a boiler furnace maintenance platform. Background technique [0002] The boiler furnace maintenance platform is an efficient and multi-functional high-altitude maintenance construction tool in the furnace. It replaces the traditional scaffolding, and the platform can be adjusted to the required position for construction work through the operation of the maintenance personnel. It has the characteristics of reasonable structure, convenient use, safety and reliability, high work efficiency, light labor intensity and short maintenance period. It is a stereotyped product widely used in the thermal power industry at present. It can be used for maintenance of various parts in the furnace. Put into use. [0003] Most boiler furnace maintenance platforms are platform structure frames assembled from 2A12 I-shaped aluminum profiles through steel connectors. Up to more than 4 tons. Therefore, for production enterprises, how to reduce th...

AI Technical Summary

Problems solved by technology

[0006] Generally, the maintenance platform is driven by a hoist to complete the lifting operation in the boiler furnace; since the inner diameter of the boiler furnace is generally tens of meters, and the peripheral size of the maintenance platform almost matches the size of the inner wall of the boiler furnace, the area of ​​the maintenance platform is too large. Huge, during the lifting process or the operation process, even if there is a small deviation, its periphery may touch the inner wall of the furnace through the guide wheel; while the installation size of the existing guide wheel on the maintenance platform is relatively fixed and basically cannot be adjusted Therefore, the pulley frame of the guide wheel is easily damaged. At the same time, the direct connection between the guide wheel and the maintenance platform is usually a rigid connection. Therefore, when the guide wheel touches the inner wall of the furnace, it is easy to cause the shake of the maintenance platform and affect the maintenance. platform security
