Railway auxiliary beam rapid transporting and erecting trailer

Abstract

The invention provides a railway auxiliary beam rapid transporting and erecting trailer. The railway auxiliary beam rapid transporting and erecting trailer comprises a suspension part trailer, a transmission part trailer, a suspension part, a transmission part, and a prefabricated auxiliary beam; the suspension part includes a control part, a hanging part, a power traction part, and a reaction frame; the transmission part includes a horizontal transferring machine and a reaction force baffle. A bottom plate of the suspension part trailer is thickened to form a counterweight part, and a slidinggroove is formed in the transmission part trailer to enable the reaction force baffle to slide; a prefabricated finished auxiliary beam is transported by the railway auxiliary beam rapid transportingand erecting trailer which is hung on a head of shunting equipment, and the automation of the installation process of the auxiliary beam is achieved by the control part coordinating cable force, support reaction of the baffle and pushing rates; after the auxiliary beam is installed in position, an upper sling is relieved and the trailer is removed along an existing line. According to the railwayauxiliary beam rapid transporting and erecting trailer, a mechanical automation technology is applied to realize the automation of the erection process of the auxiliary beam, the flexibility and the adaptability of the auxiliary beam construction are increased, and the reinforcement for the existing line and the reconstruction project are facilitated.

Description

technical field [0001] The invention relates to a trailer for fast transportation and erection of railway beams, which is especially suitable for reinforcement and reconstruction projects of existing lines. Background technique [0002] With the development of transportation projects, the reinforcement and reconstruction projects for existing railway lines are increasing day by day, and the normal operation of railway lines must be ensured during the construction period. Hanging rail beam method, beam reinforcement method, longitudinal beam reinforcement method, and I-beam beam method are some common line reinforcement methods. Among them, the beams in the reinforcement method of longitudinal and horizontal beams are widely used. The construction convenience beam bears the train load through the main beams on both sides without interrupting the operation of the line, which can ensure the normal construction of the project under the existing line. As a temporary structure, ...

Problems solved by technology

[0005] Technical issues: The existing construction technologies for erecting convenient beams, such as beam shifting method and hoisting method, all need to build convenient beams on the construction site to install additional structures or arrange multiple large-scale lifting equipment, which has high cost and low efficiency, and the construction site is often located in the traffic area. In the closed area, it is difficult for the access beam and large-scale construction equipment to enter the site, so the existing installation scheme of the beam has great limitations
