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

Embodiment Construction

[0027] 1. Equipment manufacturing

[0028] (1) Manufacture of automatic dust removal device

[0029] a. Bend the channel steel 1b into the shrinked shape of the lining trolley, and segment it in combination with 5 sections of the lining steel formwork trolley formwork. Each section is connected in a hinged manner, and a wire brush will be used as an angle grinder The angle grinder 1a is fixed to the channel steel 1b to form a group, and the distance between the angle grinder 1a is adjusted according to the size of the wire brush (angle grinder).

[0030] b. The automatic dust removal device 1 is made of two channel steels 1b fixed with several angle grinders 1a by bolts and welded side by side through steel bars, and the angle grinders 1a on the two channel steels are relatively staggered, and the automatic dust removal device It can be divided into sections in combination with the lining steel formwork trolley formwork, and the sections are connected by hinges.

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 dust-cleaning and mold-releasing device for a tunnel steel formwork trolley, which belongs to the dust-cleaning equipment for the formwork of a concrete steel formwork trolley for a tunnel in a water conservancy and hydropower project. Background technique [0002] The steel mold trolley is a special equipment designed and manufactured to improve the surface smoothness and lining speed of tunnel lining and reduce labor intensity. The steel formwork trolley has a side-top arch type, a straight-wall variable-section top arch type, a full-circle needle beam type, and a full-circle walk-through type. The basic structure of formwork trolley is composed of formwork part, gantry body part, walking system, support mechanism, translation system and other auxiliary devices. The overall order of the actual installation of steel formwork trolleys in the cave is: layered installation from inside to outside. Die and its suppor...
