Prefabricated curtain board and protecting wall formwork construction trolley for viaduct surface of high-speed train

Abstract

The invention discloses a prefabricated curtain board and protecting wall formwork construction trolley for the viaduct surface of a high-speed train. The prefabricated curtain board and protecting wall formwork construction trolley comprises a frame structure assembly, a suspension crane assembly, a double-steering-wheel assembly, a fixed single-wheel assembly, a supporting leg mechanism assembly, a frame lifting assembly, a rail beam telescopic assembly, a bottom counterweight assembly, a power electronic control assembly and the like; the frame structure assembly is a mounting bearing partof all the mechanism devices; the suspension crane assembly realizes left-right, front-rear and up-down three-dimensional movement under manipulation of a wireless remote manipulator; the double-steering-wheel assembly is the main functional part for linear and steering running of a whole machine; the fixed single-wheel assembly is also one of the main functional parts for running of the whole machine; and a power hydraulic system provides power for the frame lifting assembly and the rail beam telescopic assembly, and thus rising, falling, expanding and retracting movement requirements are met. The prefabricated curtain board and protecting wall formwork construction trolley has the functions of loading, unloading, hoisting, mounting, dismounting, storing, linear running and curve runningsimultaneously, meanwhile, operation of other working procedures is not affected, and the comprehensive efficiency is high.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a construction trolley for hoisting and installing prefabricated shutters on both sides of a high-speed railway viaduct deck, and for loading and unloading a protective wall formwork. Background technique [0002] The prefabricated shutters, protective walls and vertical walls on both sides of the high-speed railway viaduct deck are the main auxiliary bridge deck facilities for the construction of the main body of the project. The function of the prefabricated shutter is the installation foundation of the sound barrier or the prefabricated guardrail, the outer formwork of the vertical wall A pouring concrete, and the appearance of the outside of the bridge can be guaranteed. The protective wall is a high retaining wall structure, which is located on both sides of the running track line inside the sidewalk. The area between the protective walls is the track driving ...

AI Technical Summary

Problems solved by technology

The main disadvantages are: the large space occupation during construction seriously affects other processes on the bridge surface, especially the passage of beam transport vehicles, more auxiliary tools are required and the labor intensity of construction personnel is high, the overall efficiency of construction is low, the cost is high, and safety risks Big
