Abstract

The invention provides a line drawing device for tunnel blasting drilling positioning. The line drawing device is used for solving the problems that in the prior art, tunnel line drawing errors are large, and efficiency is low. The line drawing device comprises a lifting assembly capable of lifting up and down, and the lifting assembly is arranged on a movable chassis; the left-right sliding assembly can move left and right and is arranged at the lifting end of the lifting assembly; the front-back moving assembly can move front and back and is arranged on the sliding platform of the left-right sliding assembly; the swinging assembly can swing left and right and is arranged on the moving platform of the front-back moving assembly; the spraying and line drawing assembly is arranged at the swing end of the swing assembly, the spraying and line drawing assembly is driven by the rotating power assembly to rotate, and the line drawing end of the spraying and line drawing assembly corresponds to the to-be-drawn line face of the tunnel. The spraying and line drawing assembly is arranged on the mechanism capable of moving up and down, left and right and front and back, efficient and accurate line drawing of a tunnel is achieved, and meanwhile line drawing can be conducted on tunnel sections of different sizes in a matched mode.

Description

technical field [0001] The invention belongs to the field of tunnel blasting construction, and in particular relates to a line drawing device for tunnel blasting drilling positioning. Background technique [0002] In the process of tunnel construction, the more commonly used tunnel excavation method is the smooth blasting method. The smoothness and flatness of the tunnel profile is achieved by controlling the arrangement of the peripheral holes and the charging structure of the tunnel section. Before blasting the tunnel, it is necessary to draw a reference line on the tunnel section, and then make a dot on the reference line, and drill holes at the dots, and then put explosives in the holes, so as to realize the tunnel excavation construction. Therefore, it is an effective method to improve the tunnel driving footage and achieve good smooth blasting effect by using the method of drawing lines on the tunnel section to ensure the accurate positioning of the blasthole. Most o...
