Perforating device convenient for bridge building to use

Abstract

The invention discloses a perforating device convenient for a bridge building to use. The perforating device comprises a U-shaped plate. Sliding grooves are formed in the two sides of the inner wall of the U-shaped plate. The tops and the bottoms of the inner walls of the sliding walls are connected through sliding rods. The sliding rods are sleeved with sliding blocks connected to the interior of the sliding grooves in a sliding mode. Damping springs are connected to the portion, above the sliding blocks, on the sliding rods in a sleeving mode. The two ends of the damping springs are fixedly connected with the tops of the inner walls of the sliding grooves and the tops of the sliding blocks respectively. The opposite sides of the two sliding blocks are connected through a sliding plate. A stretchable air cylinder is fixedly connected to the top of the inner wall of the U-shaped plate. According to the perforating device convenient for the bridge building to use, by improving a drill bit, when the stretchable air cylinder is started, the sliding plate can be pushed to move up or down, by cooperation use of the sliding rods inside the sliding grooves, the sliding blocks can drive the sliding plate to stably move up and down, and therefore the sliding plate can push a drill rod on a motor to stably move up or down, and the drill rod can be retracted into or stretch out of the U-shaped plate.

Description

technical field [0001] The invention relates to the technical field of bridge construction equipment, in particular to an easy-to-use drilling device for bridge construction. Background technique [0002] A bridge refers to a building erected on rivers, lakes and seas to enable the smooth passage of vehicles and pedestrians. It is called a bridge. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the abutment; the auxiliary structures refer to the bridge head board, conical slope protection, bank revetment and diversion works, etc. Drilling equipment is used in bridge construction projects. [0003] When the existing punching equipment for bridge construction is in use, the staff usu...
