Plate turnover device with internal protection function for tunnel construction

Abstract

The invention discloses a plate turnover device with an internal protection function for tunnel construction, and belongs to the technical field of tunnel construction. The plate turnover device comprises a bottom box and a shell, wherein the upper surface of the bottom box is fixedly connected with the shell, a discharging port is formed in the left side surface of the shell, a pushing mechanism is arranged on the shell, an adjusting mechanism and a damping mechanism are arranged in the shell, and the damping mechanism and the adjusting mechanism are located on the lower side and the upper side of the pushing mechanism respectively. According to the plate turnover device, a turnover mechanism is arranged, a control motor works to drive a first threaded column to rotate, the first threaded column rotates to drive a first threaded cap to move, at the moment, two pressing plates drive two racks to move respectively, the racks move to drive a gear to rotate, a second threaded column rotates to be driven by a second threaded cap, the second threaded cap drives a clamping plate to move through an L-shaped rod, so that the clamping plate moves leftwards to extrude a plate, at the moment, the plate is fixed, and a worker can conveniently operate the plate.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and in particular relates to a plate turning device for tunnel construction with an internal protection function. Background technique [0002] Tunnel engineering is an underground structure, and there are various underground structures, as well as various construction methods and technologies for constructing underground structures. Construction methods and techniques form and develop in relation to the characteristics of underground structures. Its characteristic is that the vertical length is from a few meters to more than ten kilometers, and the section is relatively small, generally 5-6m high and 5-10 meters wide. [0003] During the tunnel construction process, it is necessary to turn the horizontal board to the vertical position so that the board can be attached to the tunnel wall. At this time, the board can be installed conveniently, but the board is large in size and heavy ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the need to turn the horizontal board to the vertical position during the tunnel construction process, so that the board can be attached to the tunnel wall, and the board can be installed conveniently at this time, but the board is large in size and heavy It is heavy, and workers need to turn it over manually during use. Not only is the operation troublesome and the volume of workers is wasted, but also if the workers lose their strength and cannot hold the board, accidents may occur, and the transportation of the board during the processing is troublesome, so a large number of boards need to be installed It is very troublesome to transport and use one by one, which brings great inconvenience to the tunnel construction, and the proposed plate turning device with internal protection function for tunnel construction
