A kind of empty vehicle for highway bridge construction

Abstract

The invention discloses an idling trolley for highway bridge construction, and relates to the field of highway bridge equipment. The idling trolley comprises an idling trolley body, wherein a connecting frame is fixedly welded to the upper surface of the right end of the idling trolley body; the connecting frame is of an inverted U-shaped structure; an electric push rod II is fixedly welded to theleft lower end of the connecting frame; the lower end of the electric push rod II is fixedly welded to the right upper end of a walking base plate; two sets of reserved holes are arranged in the upper surface of the walking base plate; and connecting inserting rods are inserted into the two sets of reserved holes in a matched mode. Through a front-back movable hanging structure of a rotatable elevator of the idling trolley body disclosed by the invention, the body can get off of the bridge conveniently while the maintenance in all directions of the bridge is realized, and a transverse movingstructure is not needed; the stability of the idling trolley body is increased through an inner guide wheel and an outer guide wheel, and the safety is high; and a balancing weight is convenient to take and place and convenient to use.

Description

technical field [0001] The invention relates to the field of road and bridge construction equipment, in particular to an empty vehicle for road and bridge construction. Background technique [0002] In the construction of highway bridges, it is usually necessary to maintain and overhaul the exterior of the bridge. In the prior art, suspension ropes and fixed structures are usually used, or lift vehicles are used to carry personnel. The stability and safety of lift vehicles and suspension ropes are low, which improves Risks to personnel in road and bridge construction. Therefore, it is very necessary to invent a kind of road bridge construction to solve the above-mentioned problem with empty vehicle. [0003] In the prior art CN101487230A and CN103015314A, the walking body is set on the bridge, and the hanging basket is set on the outside of the bridge railing, but this design requires frequent movement of the hanging basket on the bridge during transportation, getting off t...

Problems solved by technology

[0003] In the prior art CN101487230A and CN103015314A, the walking body is set on the bridge, and the hanging basket is set on the outside of the bridge railing, but this design requires frequent movement of the hanging basket on the bridge during transportation, getting off the bridge, and storage. The walking body even needs to be equipped with the cooperation of a lateral movement mechanism to complete the above actions. In addition, for the external cleaning or maintenance of inclined bridge railings, it is necessary to move the walking body back and forth frequently, and the arc transition area of ​​the bridge railing also requires frequent Move the walking body on the bridge
