A service device for mechanized hanging metal mesh

Abstract

The invention provides a serving device for hanging metal net in a mechanized mode. The serving device for hanging the metal net in the mechanized mode comprises a frame-shaped working framework, one side of the working framework is provided with a guide rail, and the guide rail is provided with a net pushing mechanism controlled by a net pushing hydraulic system; the net pushing mechanism comprises a rack located on the guide rail, a length control arm is fixed on the rack, the top end of the length control arm is provided with a mechanical arm, the bottom end of the length control arm is provided with an angle control arm which is movably connected with the length control arm, and the other end of the angle control arm is movably connected with the lower portion of the working framework. According to the serving device for hanging the metal net in the mechanized mode, the problems that in spray anchor net supporting projects such as underground mine roadways, highway and railway transportation tunnels and water conservancy and hydropower tunnels, when the metal net is hung manually, the labor intensity is high, the construction efficiency is low, and the risk is high are solved, the safety risk of operating personnel in the supporting process is lowered, the spray anchor net supporting working efficiency is improved, the supporting effect is improved, and the mechanization level of spray anchor net supporting is promoted.

Description

technical field [0001] The invention belongs to the field of machinery and relates to a service device for metal nets, in particular to a service device for mechanized hanging metal nets. Background technique [0002] With the increase of mine mining depth, the mining intensity and engineering volume are also increasing year by year. In addition to the expansion of mining scope and the influence of unfavorable factors such as complex engineering geological conditions, high stress, and rock mass fragmentation, the surrounding rock of the mine roadway shows obvious fragmentation. Due to the expansion characteristics, the roadway shows great ground pressure, especially in mines with broken rock mass and poor lithology, when shallow excavation, it shows strong ground pressure, large roadway deformation and serious damage, such as Jinchuan Ni Mine, Jinfeng Gold Mine, etc. The tunneling support of broken rock mass roadway is difficult, high cost, repair rate and repair cost are a...

AI Technical Summary

Problems solved by technology

In this manual installation method, the staff must stand under the unsupported roof to work, which greatly increases the safety risk of the staff; the use of manual suspension metal mesh requires 3 to 4 people to cooperate with each other, and the work efficiency is low and the labor intensity is high. ; At the same time, due to the limited artificial force, it is easy to appear that the metal mesh does not fit the rock wall, and the metal mesh is loose.

Moreover, the traditional hanging net must rely on blasting piles and erecting workbenches, etc., which complicates the support process, greatly reduces the efficiency of roadway excavation, and increases the safety risk of construction personnel
