A disembarkation system of anti-reversing bridge-erecting unit and a bridge-erecting method using it

Abstract

The invention discloses an alighting system of an anti-reversing bridging unit and a bridge erecting method using the same, comprising: detachable anchor bolt mechanisms arranged on both sides of the front end of the alighting system's alighting car body, the anchor The bolt mechanism includes: an anchor chain, an anchor rod, an anchor rod nut, an upper anchor chain shackle, and an anchor chain lower shackle; wherein, the upper end of the anchor rod is connected to the lower end of the anchor chain through the lower anchor chain shackle; The lower end of the anchor rod is threaded and connected to the anchor rod nut; a lug plate with a hole is welded on both sides of the front end of the main beam of the vehicle frame of the alighting system, and the lug plate with a hole passes through the shackle on the anchor chain and The upper end of the anchor chain is connected. The invention utilizes the self-weight of the erected concrete beam and its hanging beam hole, and anchors the front end of the beam transport vehicle on the erected beam head through the anchor bolt mechanism, so as to prevent the system from tipping backwards when the bridge erecting unit erects the beam , which ensures the longitudinal stability of the alighting system, and has the advantages of simple structure, safe performance and low cost.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to an alighting system of an anti-reverse tilting bridge erecting unit and a bridge erecting method using the same. Background technique [0002] The bridging unit is mainly composed of a boarding system and a disembarking system. The boarding system is mainly composed of the main structure of the bridge crane and the overhead crane, and the disembarking system is also served by a tire-type beam transporting vehicle. The boarding and disembarking systems are used in conjunction with each other, and the steps for erecting the beam are as follows: [0003] Step 1, see Picture 1-1 , the loading system of the bridge crane is in the state of rear cantilever beam feeding, the rear-end walking outriggers are tilted backwards, the rear outriggers are retracted after bearing the load, and the alighting system (that is, the tire-type beam transporter) transports the concrete b...
