Maintenance scaffold for bridge girder erection machine

Abstract

The invention discloses a maintenance scaffold for a bridge girder erection machine. The maintenance scaffold comprises a storage tank, rollers, a lifting device and a heightening device, wherein the lifting device comprises a jack and a lifting baffle; the jack is fixedly connected to the upper end of the storage tank; the lifting baffle is fixedly connected to the upper end of the jack; the rollers are positioned at the lower end of the storage tank; the heightening device is arranged at the upper end of the lifting baffle and comprises heightening support columns and a heightening plate; a first convex post is arranged at the lower end of each heightening support column; a convex ring is arranged at the upper end of each heightening support column; the inner part of each convex ring is matched with the corresponding first convex post; openings matched with the first convex posts are formed in the lifting baffle; openings matched with the convex rings are formed in the heightening plate. The maintenance scaffold disclosed by the invention is simple in structure and is convenient to operate; in addition, the construction height can be adjusted in the use process; besides, by using the storage tank, the aim of improving the construction height is achieved; meanwhile, the heightening support columns and the heightening plate are effectively stored, and the loss of equipment is effectively prevented.

Description

technical field [0001] The invention relates to the field of maintenance equipment, in particular to a maintenance scaffold for bridge erecting machines. Background technique [0002] At present, the bridge erecting machine includes front outriggers, rear supports, front supports, rear supports, beams and winch trolleys that can move longitudinally. It is folded and shrunk at the end of the beam, and the front outriggers are set directly on the ground. The specific front support and rear support mainly support the weight of the bridge erecting machine. At the same time, two beam transport trolleys are used to transport the bridge to be erected. The two ends of the bridge to be erected are hoisted up by the hoisting crane, so that the bridge to be erected is separated from the beam transport trolley, and further under the action of the hoisting crane, the bridge to be erected is moved to the beam erection area, and the hoisting crane is used to move the bridge to be erected. ...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, when the bridge erecting machine is overhauled, because the height of the position where the bridge erecting machine needs to be overhauled is generally high, it is very inconvenient to overhaul. Designing a maintenance scaffold to overhaul the bridge erecting machine is a problem that needs to be solved in the current prior art question
