Abstract

The invention provides a transverse drilling mechanical device for vertical columns of a corrugated beam steel guardrail. The transverse drilling mechanical device comprises a base, a lifting platformis fixedly connected to the base and connected with a longitudinal pipeline lift which can move up and down on the lifting platform, a transverse V-shaped support is fixedly connected to the longitudinal pipeline lift, a guiding frame is fixedly connected to the support and comprises a fixed disc and a movable disc, a drilling machine is fixedly connected to the movable disc, a second through hole is formed in the movable disc, the drilling machine penetrates through the second through hole to be fixedly connected with the movable disc, the end with a chuck of the drilling machine faces the fixed disc, and the center of the chuck and the center of a first through hole are located on the same straight line. The transverse drilling mechanical device can drill the constructed usable guardrail directly without dismantling the guardrail for machining, and it can be ensured that the line shape and straightness of the drilled guardrail reach optimal.

Description

technical field [0001] The invention relates to the technical field of opening holes for guardrail columns, in particular to a mechanical device for horizontally opening holes for corrugated beam steel guardrail columns. Background technique [0002] Corrugated beam steel guardrail is a common protective device in ordinary national and provincial highways. Its traditional construction technical procedures are ①temporary traffic control, ②removal of corrugated beam slabs, ③existing column removal, ④sealing of holes, ⑤displaced drilling and piling, ⑥hanging boards, ⑦installation of delineation guide marks, ⑧handover and acceptance. During the drilling process, traditional drilling tools for corrugated beam steel guardrails cannot guarantee the accuracy of drilling and the efficiency of construction. The accuracy of drilling plays an important role in the control of the height, straightness and anti-collision performance of the corrugated beam. Contents of the invention [...
