A device for automatic dust cleaning and coating release agent for tunnel steel formwork trolley

Abstract

The invention provides an automatic dedusting and demoulding agent brushing device for a tunnel steel trolley. The device is characterized in that the device is composed of an automatic dedusting device and an automatic demoulding agent brushing device and is of a portal-shaped frame structure, and the automatic demoulding agent brushing device is arranged behind the automatic dedusting device and is fixed to an inner wall of a tunnel through a fixing and adjusting device; an automatic dedusting and demoulding device for the tunnel steel trolley is arranged in advance, a pump machine or a sprayer and all angle grinders with steel wire brushes as angle grinding pieces are started when the trolley is moved in place, and accordingly the steel trolley passes through the automatic dedusting device firstly in the moving process, a steel trolley formwork is ground and dedusted through the angle grinding pieces of the angle grinders in the passing process, then the steel trolley passes through the automatic demoulding agent brushing device, demoulding agents are continuously pressed into rolling cotton brushes through steel tubes by means of the pump machine or the sprayer in the automatic demoulding agent brushing device, and the rolling cotton brushes roll due to friction force of the trolley and finish demoulding agent brushing construction of the steel trolley formwork.

Description

technical field [0001] The invention relates to an automatic ash cleaning and release agent coating device for a tunnel steel formwork trolley, which belongs to a water conservancy and hydropower engineering tunnel concrete steel formwork trolley formwork ash cleaning device. Background technique [0002] The steel mold trolley is a special equipment designed and manufactured to improve the surface finish and lining speed of tunnel lining and reduce labor intensity. Steel mold trolleys include side top arch type, straight wall variable section top arch type, full-circle needle beam type, full-circle travel type, etc. The basic structure of the formwork trolley is composed of the formwork part, the gantry body part, the walking system, the support mechanism, the translation system and other auxiliary devices. The overall sequence of the actual installation of the steel mold trolley in the hole is: layered installation from the inside to the outside. The specific order of ins...

AI Technical Summary

Problems solved by technology

[0004] Because the thickness of the tunnel concrete lining is generally thin, and in order to speed up the concrete lining, the lining reinforcement is generally completed 2 standard warehouses ahead, resulting in a relatively narrow operating space, slow manual cleaning speed, poor quality, and poor working environment

The manufacturing cost of the steel formwork trolley is relatively high, and it is unrealistic to invest in multiple sets of steel formwork trolleys, and each steel formwork trolley is heavy and bulky. It must be disassembled in the tunnel for dust cleaning and application of release agent. Unfeasible in terms of cost and construction period
