The invention discloses a tunnel surrounding rock drilling vehicle. The tunnel surrounding rock drilling vehicle comprises a base, wherein a fixed block is fixedly connected to the right side of the bottom of the inner wall of the base; a second adjusting cylinder is movably connected to the front side of the fixed block; the output end of the second adjusting cylinder is movably connected with afloor pole; a fixed column penetrates through the inner cavity of the floor pole; the top of the floor pole penetrates to the top of the base; a positive and negative motor is fixedly connected to thetop of the floor pole; the output end of the positive and negative motor is fixedly connected with a screw rod; and a limiting plate is fixedly connected to the top of the screw rod. According to thetunnel surrounding rock drilling vehicle, the floor pole is pushed to move by the second adjusting cylinder, the floor pole rotates around the fixed column, the floor pole rotates in a rotary groove,the positive and negative motor and the screw rod are driven by the rotation of the floor pole to rotate, and a drilling box rotates left and right by the rotation of the screw rod, so that the advantage of angle adjustment is achieved, and the problem that the angle cannot be adjusted when a conventional tunnel surrounding rock drilling vehicle is used is solved.
Description
technical field [0001] The invention relates to the technical field of surrounding rock, in particular to a tunnel surrounding rock drilling vehicle. Background technique [0002] In underground rock engineering, the surrounding rock mass whose stress state changes due to the influence of excavation is called surrounding rock, and surrounding rock is also called host rock and ore-hosting rock. When constructing the surrounding rock, it is necessary to use a drilling vehicle. The existing tunnel surrounding rock drilling vehicle cannot adjust the angle during use, and often can only drill vertically, so that it cannot meet people's construction needs and is not convenient for people to use. . Contents of the invention [0003] (1) Solved technical problems [0004] Aiming at the deficiencies of the prior art, the present invention provides a tunnel surrounding rock drilling vehicle, which has the advantage of adjustable angle, and solves the problem that the existing tunn...
