A trolley used for inverted arch construction

Abstract

The invention discloses a trolley for construction of an inverted arch. The trolley comprises a template system, a main beam, a door frame, a supporting system, a template moving device system, a traveling system and a hydraulic control system, wherein the main beam is of a triangular stand structure, is formed by welding profiles, and is used for carrying a whole template during pouring and traveling; the hydraulic system consists of a pump station, a pipeline valve and an oil cylinder and is used for adjusting mold erection and demolding of the template and upward movement of the main beam and separation of a track from the ground during traveling of a whole trolley system. The trolley has the advantages that firstly, the trolley is simple to operate and accurate in mold alignment; secondly, the anti-floating property is good, and the mold cannot run away easily; thirdly, the track can travel automatically, repeated pavement is not required, and labor is reduced; fourthly, double sides are constructed simultaneously, and working efficiency is improved; and fifthly, counterweight is carried out at a time, and repeated assembling, unloading and counterweight are not required. The trolley is a lining trolley suitable for construction of the inverted arch.

Description

Technical field [0001] The present invention relates to a trolley, specifically to a trolley suitable for invert construction of large-section medium and long tunnel engineering such as railways, highways, water conservancy, municipal administration and the like. Background technique [0002] At present, truss block construction, cantilever construction, and trestle integrated construction are commonly used in invert construction. Among them, the truss briquetting construction has light weight, less one-time investment, and has certain advantages in saving materials, but it cannot walk on its own during the construction process, which increases the difficulty of construction. However, the integrated construction of the trestle bridge can walk as a whole after the concrete is poured, but the whole is heavy and the construction is not flexible. In this type of construction, they still have many shortcomings, mainly as follows: [0003] The disadvantages of truss block construction a...

AI Technical Summary

Problems solved by technology

[0004] 1. Heavy, inflexible construction, the whole system needs large-scale equipment hoisting and moving

[0005] 2. Both ends of the truss need briquetting counterweights, and each cycle construction requires equipment to install or remove briquetting counterweights, and the construction is cumbersome

[0006] 3. The mold setting speed is not fast, and it is not necessarily accurate. For the overlapping joint of the second lining construction, the staggered platform is relatively large

[0007] 4. It can only be constructed on one side, and the construction efficiency is low

[0008] 5. Fully manual operation, so the use cost is high

[0010] 1. The mold is not accurate, and it is easy to be wrong at the overlap with the second lining

[0011] 2. The floating resistance is poor, and the upper part of the cantilever beam needs counterweight, which causes great trouble to the construction

[0013] 1. Heavy, inflexible construction and difficult operation
