Changeable type extending-retracting transverse-movement reinforcing steel bar trolley

Abstract

A changeable type extending-retracting transverse-movement reinforcing steel bar trolley comprises a supporting portal frame and a bearing frame arranged on the upper portion of the supporting portalframe. The supporting portal frame comprises vertical supporting structures, a transverse supporting beam, longitudinal supporting beams and walking connection beams. Each vertical supporting structure comprises a stand column and a jacking system. The changeable type extending-retracting transverse-movement reinforcing steel bar trolley is characterized in that the bearing frame is of a multi-layer platform three-dimensional frame type structure and comprises a platform supporting system, a top platform arranged on the top of the platform supporting system and side face extending and retracting platforms hinged to the two sides of the platform supporting system, the top platform is composed of multiple layers of overturning frames capable of extending upwards and a steel cover plate, thetwo ends of each longitudinal walking connection beam are provided with walking mechanisms capable of turning, and each walking mechanism comprises a walking wheel group arranged on a walking rail. After the changeable type extending-retracting transverse-movement reinforcing steel bar trolley extends, the requirement for reinforcing steel bar installation of a large-section tunnel can be met, after installation is completed, the changeable type extending-retracting transverse-movement reinforcing steel bar trolley can pass through a small-section construction channel to transversely move to an adjacent tunnel through retraction of the own structures, and then the changeable type extending-retracting transverse-movement reinforcing steel bar trolley extends and recovers to original dimensions, and reinforcing steel bar installation continues to be conducted; and in this way, autonomous transferring between the tunnels and cyclic utilization are achieved.

Description

technical field [0001] The invention relates to the field of tunnel lining construction, in particular to a trolley device that can be transferred autonomously between tunnels and satisfies cavern grouting construction. Background technique [0002] In large-scale underground water diversion power generation system projects, there are usually multiple hydraulic tunnels such as water diversion tunnels and draft pipes arranged in parallel. The size of the construction branch tunnels arranged in the above positions is generally smaller than the section size of the main cavern. As a result, when conventional steel bars, steel formwork trolleys, and grouting trolleys are used for construction, the trolleys cannot be independently transferred and recycled among the tunnels, and repeated dismantling is required. Installing trolleys or investing multiple trolleys for construction will affect the construction progress, increase construction costs, and reduce equipment utilization. ...
