The hydraulic cylinder 42 is used for driving the mounting plate 43, the drilling machine 44 and the drill bit 45 to move linearly. The output end of the drilling machine 44 is used for driving the drill bit 45 to rotate at high speed, so that the tunnel wall can be punched. The electric telescopic rod 47 is used for controlling the stop block 48 and the laser ranging sensor 49 to move linearly horizontally, and then the distance between the stop block 48 and the contact plate 411 can be adjusted.

The support frame 412 and the arc-shaped resisting plate 413 are designed to support and reinforce the surrounding area of the tunnel wall drilled by the drill bit 45, so as to limit the loosening of the surrounding rock or soil around the drilling area of the tunnel wall and reduce the risk of falling of the surrounding rock or soil.

[0029] In the embodiment, a power box 7 with an open top structure is fixedly installed at the top left side of the plate 1. A storage battery group 8 is fixedly installed in the power box 7. A controller 9 is fixedly installed on the front outer wall of the power box 7. A display and a plurality of control buttons are arranged on the controller 9. The storage battery group 8 is electrically connected with the controller 9. The multi-axis mechanical arm 3, the hydraulic cylinder one 42, the drill 44, the electric telescopic rod 47, the laser ranging sensor 49, and the hydraulic cylinder two 10 are electrically connected with the controller 9. The storage battery group 8 is used to supply power to the multi-axis mechanical arm 3, the hydraulic cylinder one 42, the drill 44, the electric telescopic rod 47, the laser ranging sensor 49, the hydraulic cylinder two 10, and the controller 9. The plurality of control buttons are used to control the multi-axis mechanical arm 3, the hydraulic cylinder one 42, the drill 44, the electric telescopic rod 47, the laser ranging sensor 49, and the hydraulic cylinder two 10 to be powered and operated. The data value measured by the laser ranging sensor 49 can be displayed on the display, so as to facilitate the staff to check the value. Since the connection mode and the drilling mode are mature technologies in the art, they have been fully disclosed, and thus will not be described herein.
[0030] Through the above structure, the tunnel punching device provided by the application is used first. The whole punching device is pushed into the working area needing punching in the tunnel. The multi-axis mechanical arm 3 is controlled to run. The drill bit 45 is adjusted to the required angle. The drill bit 45 is aligned with the part needing punching on the tunnel wall. Then the whole device is moved. The arc-shaped abutting plate 413 is tightly abutted and fitted on the tunnel wall. The hydraulic cylinder two 10 is controlled to extend and run. The output end of the hydraulic cylinder two 10 pushes the positioning plate 11 and the anti-skid pad 12 to vertically descend until the anti-skid pad 12 tightly abuts the ground in the tunnel, and the hydraulic cylinder two 10 stops running. At this time, the whole punching device can be stably fixed on the ground. During the subsequent punching operation, the whole punching device can be ensured not to be displaced.
[0031] Subsequently, the hydraulic cylinder one 42 is controlled to extend and run. The output end of the hydraulic cylinder one 42 pushes the mounting plate 43, the drilling machine 44 and the drill bit 45 to move linearly. The mounting plate 43 drives the guide sliding plate 410 and the abutting plate 411 to move. When one end of the drill bit 45 enters the avoiding hole 414 and abuts the tunnel wall, the hydraulic cylinder one 42 is paused. Then the laser ranging sensor 49 is started, and the electric telescopic rod 47 is controlled to extend and run. The electric telescopic rod 47 pushes the stop block 48 and the laser ranging sensor 49 to move linearly. The distance between the stop block 48 and the abutting plate 411 gradually decreases. At this time, the distance between the stop block 48 and the abutting plate 411 can be measured by the laser ranging sensor 49. This distance is the depth of the drill bit 45 drilled into the tunnel wall. When the distance between the stop block 48 and the abutting plate 411 is adjusted to the required punching depth value, the electric telescopic rod 47 is stopped. The operation of punching depth adjustment and control is completed.
[0032] Then, the drilling machine 44 is controlled to run, driving the drill bit 45 to rotate at high speed. Then the hydraulic cylinder one 42 is controlled to extend and run again. The output end of the hydraulic cylinder one 42 pushes the mounting plate 43, the drilling machine 44 and the drill bit 45 to move linearly. The mounting plate 43 drives the guide sliding plate 410 and the abutting plate 411 to move. The tunnel wall can be punched by the high-speed rotating drill bit 45. When the abutting plate 411 moves to abut the stop block 48, the precise control of the punching depth is completed. The drilling machine 44 is paused. The drill bit 45 is moved out of the drilled hole by controlling the hydraulic cylinder one 42 to reset. Then the hydraulic cylinder two 10 is controlled to reset. The positioning plate 11 and the anti-skid pad 12 are lifted back to the original position. The punching device can be pushed to the next punching area. According to the above operation steps, the hole with the required depth can be precisely punched in the next punching area.
