Anti-collision guardrail lifting appliance for bridge construction

Abstract

The invention discloses an anti-collision guardrail lifting appliance for bridge construction, and relates to the technical field of anti-collision guardrail lifting appliances. The anti-collision guardrail lifting appliance comprises an anti-collision guardrail body, a lifting arm and a lifting rod; anti-collision guardrail top pipes are installed on the two sides of the top of the anti-collision guardrail body, a steel pipe is installed on the anti-collision guardrail body, a sliding groove is formed in the lifting arm, a piston is mounted in the sliding groove, a lifting claw is mounted on one side of the piston, a locking assembly is mounted on one side of the end of the lifting claw, a reinforcing claw is mounted on one side of the bottom of the lifting arm, a mounting base is mounted on the reinforcing claw, a fixing rod is mounted on the top of the mounting base, and a clamping claw assembly is mounted on the mounting base. According to the anti-collision guardrail lifting appliance, the lifting claw is arranged to be in the cylindrical shape, the anti-collision guardrail can be locked only by penetrating the lifting claws through the anti-collision guardrail top pipe, and the installation speed is increased; and the reinforcing claw is arranged on the lifting arm, so that the friction force between the lifting claw and the anti-collision guardrail is reduced, and the service life of the lifting claw is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of an anti-collision guardrail spreader, and in particular relates to a spreader for an anti-collision guardrail used in bridge construction. Background technique [0002] The anti-collision guardrail spreader is a tool used to lift the anti-collision guardrail. During the construction of the bridge, the anti-collision guardrail is installed on both sides of the bridge to improve the safety performance of the bridge. When the anti-collision guardrail is installed, due to the anti-collision guardrail The collision barrier is heavy and needs to be hoisted by a crane, so a special spreader is required. The existing anti-collision barrier spreader has low safety, the lifting claws cannot lock the crash barrier, and the spreader cannot firmly grasp Collision guardrail, based on the problem that occurs above, proposes a kind of hanger with anti-collision barrier for bridge construction.
