Walking support of rail-free construction work vehicle

Abstract

The invention relates to a walking support of a rail-free construction work vehicle. The walking support comprises a fixing plate. An adjusting connecting rod and an adjusting pipe are connected witheach of the two sides of the fixing plate, a supporting rod is connected in each adjusting pipe in an inserted mode, a first oil cylinder is connected between each adjusting pipe and the correspondingsupporting rod, hinge seats are hinged to the lower sides of the supporting rods, wheel covers are connected to the hinge seats through rotating shafts, wheels are installed in the wheel covers, a motor for driving the corresponding wheel is installed on one side of each wheel cover, second oil cylinders are connected between the supporting rods and the hinge seats in a matched mode, and third oil cylinders are connected between the hinge seats and the wheel covers in a matched mode. The walking support has the advantages that rail-free running is achieved, the walking support adapts to operation of various construction working conditions, on and off of construction personnel are convenient, the wheel distance and the height of a frame can be changed through the frame, walking and construction in different working conditions are convenient, walking on a rectangular face and a circular arc face can be achieved, an operation vehicle is supported through four walking devices, distribution is in balance, hydraulic braking is adopted, reliability and stability are achieved, and plane construction and circular arc tunnel construction can be met in a variable angle mode.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a walking support for a trackless construction vehicle. Background technique [0002] Auxiliary facilities such as power cables, communications, PIS cables, fire-fighting ventilation pipes, and evacuation platforms are required for construction in railway and subway tunnels. At the current stage of construction, each type of work requires a specific construction frame for construction personnel to use. , there are some types of work, such as the evacuation platform does not have a professional construction platform for use, so at this stage there is an urgent need for a work platform suitable for various types of work for construction personnel to use. In order to solve the above technical problems, the applicant designed A trackless working vehicle, the application is a traveling support for the working vehicle. Contents of the invention [0003] The object of the...
