Problems solved by technology

[0002] Now the walls of the tunnel need to be sprayed with a kind of fireproof material to prevent the car from catching fire in the tunnel, causing the tunnel wall to be burned and causing great losses to the steps inside the tunnel. However, because the wall is too smooth, it is difficult for the fireproof material to adhere to it.

Embodiment Construction

[0005] The production principle of the present invention is as shown in the figure, is made of vibrating rod 1, vibrating frame 2, vibrating machine 3, pneumatic cylinder 4,5, piston type connecting rod 6,7, fixed base 8.

[0006] The conditions for constituting the device of the present invention are: the vibrating rod 1 is inlaid with an alloy steel head, is rotatably connected with the vibrating frame with a bearing, the pneumatic cylinders 4 and 5 are pushed with specific gas, and the base 8 is installed on the mechanical frame.

[0007] From the conditions specified above, it can be concluded that the pneumatic cylinders 4 and 5 push the vibrating frame 2 so that the vibrating rod fits on the wall, and the wall can be drilled when the vibrating machine is turned on, and then the base 8 is pushed to move according to the regulations. It can roughen large areas of walls.

Abstract

The invention relates to a tunnel wall-roughening device, in particular to a wall-roughening machine aiming at the situation that the traditional highway tunnel walls are very smooth and difficult forfireproof material to be sprayed to attach. The invention solves the objective factor of slow manual punching and shortens the project duration.

Description

technical field [0001] The invention relates to a wall roughening device. Background technique [0002] The existing tunnel walls need to be sprayed with a kind of fire-proof material to prevent cars from catching fire in the tunnel, causing the tunnel wall to burn and causing great losses to the steps in the tunnel. However, because the walls are too smooth, the fire-proof material is difficult to adhere to. This device is aimed at this characteristic, designs a kind of roughening machine, and this device has high working efficiency, has greatly improved the situation of manual chiseling slow, has saved the construction period. Contents of the invention [0003] Aiming at the fact that the wall of the tunnel needs to be roughened during the process of spraying materials, due to the objective factors of large area of ​​the tunnel wall and slow manual chiseling, a tunnel roughening machine is specially designed. Description of drawings [0004] Accompanying drawing is th...
