Assembly type lining trolley capable of being used for various section sizes

Abstract

The invention discloses an assembly type lining trolley capable of being used for various section sizes. The assembly type lining trolley comprises a portal frame assembly, a formwork assembly, a jacking device, a horizontal pushing device, a walking mechanism and a steering mechanism, wherein stand columns and a cross beam are of telescopic structures; the formwork assembly is detachably arrangedon the cross beam; the jacking device adjusts the height of the stand columns, and the horizontal pushing device adjusts the length of the cross beam; the walking mechanism is controlled by the steering mechanism and at least has the transverse or vertical walking direction; the stand columns and the cross beam are of the telescopic structures, the height of the stand columns is adjusted throughthe jacking device, the length of the cross beam is adjusted through the horizontal pushing device, and the assembly type lining trolley can be qualified for lining construction of various section sizes; due to the fact that the formwork assembly is detachable, the formwork assembly can be detached before adjustment; and the walking mechanism can rotate, when the cross beam is lengthened or shortened, the walking mechanism drives the stand columns, a lower longitudinal beam and an upper longitudinal beam at the two ends of the cross beam to get away from or get close to one another, the structure is reasonable, the splicing, detaching and transferring time is greatly saved, and therefore the construction period is shortened.

Description

technical field [0001] The invention relates to the technical field of tunnel construction equipment, in particular to an assembled lining trolley that can be used in various cross-sectional sizes. Background technique [0002] The traditional lining construction adopts the traditional scaffolding scheme, that is, repeatedly builds scaffolding and formwork according to different sections and performs multiple turnovers to complete the lining construction. This method is not only time-consuming and labor-intensive, but also the quality of the lining is difficult to guarantee. Deformation, splicing seams, and wrong tables are serious. Now some trolleys are used to complete the lining construction, but the same tunnel usually needs to design several cross-sectional forms with different sizes. In the construction stage, if a trolley is made for each section form, it will undoubtedly increase the construction cost, especially when the lining must maintain a reasonable distance f...

Problems solved by technology

In the construction stage, if one trolley is made for each section form, it will undoubtedly increase the construction cost, especially when the lining must maintain a reasonable distance from the tunnel face under the condition of poor surrounding rock, multiple trolleys The assembly and disassembly of trolleys in the tunnel will inevitably delay the construction progress and greatly increase the difficulty of transporting materials and muck in the tunnel
