An automatic punching vehicle in road construction

Abstract

The invention discloses an automatic punching vehicle in road construction. The vehicle comprises a punching vehicle shell, wherein a working cavity is formed in the punching vehicle shell. A punchingassembly is arranged in the working cavity; the punching assembly comprises a horizontal support fixedly arranged on the inner wall of the right side of the working cavity, a threaded shaft rotationally connected to the horizontal support and extending up and down, an internal thread sliding block connected to the inner wall of the rear side of the working cavity in a sliding manner and in threaded connection with the thread part on the threaded shaft, and a rotating shaft bracket fixedly arranged at the left end of the internal thread sliding block. By the adoption of a sector gear and a fixing block, when the sector gear is connected with a toothed part of the fixing block on the lower side in an engaged mode, power transmission of an advancing assembly can be achieved, and therefore leftward movement of the punching vehicle is achieved; when the sector gear is connected with the toothed part of the upper side fixing block in a meshed mode, power transmission of the punching assembly can be achieved, so that automatic punching operation on the road ground is achieved, manual marking work is not needed during punching, and efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of road construction tools, in particular to an automatic drilling vehicle for road construction. Background technique [0002] In road construction, sometimes in order to reserve a flag position on the ground, it is often necessary to drill holes on the ground.
