Problems solved by technology

The assembly of this simple platform not only takes up a lot of skylight time, but also does not have the function of adjusting the spatial position of the working platform, and the position of the working platform cannot be adjusted at any time according to the needs of disease control, resulting in high work intensity and low efficiency for workers
At present, there is no report on the mechanized operation platform used for disease control of existing railway tunnels

Embodiment Construction

[0018] see Figure 1-6 , the composition of the trolley for the comprehensive improvement of the existing line railway tunnel disease includes a running mechanism 25, a fixed stand fixed on the running mechanism 25, a lift-type top floor operation platform arranged on the fixed stand, and a turning-type top-floor operation platform with a turning mechanism. The lower operating platform is composed of a retractable upper operating platform with a retractable mechanism, wherein the fixed platform is composed of an installation platform 21 installed on the running mechanism 25, and columns 12 symmetrically fixed on both sides of the installation platform 21 1. The lower longitudinal beam 6 connected to the upper end of each column 12 and the lower cross arm 22 constitute. The lift-type roof work platform is composed of a guide sleeve 10 installed inside the column 12, a lifting hydraulic cylinder 24 hinged between the guide sleeve 10 and the column 12, and an upper longitudinal b...

Abstract

The invention discloses an existing line railway tunnel defect comprehensive improvement operation trolley, and belongs to the technical field of tunnel defect improvement construction equipment. The existing line railway tunnel defect comprehensive improvement operation trolley is composed of a walking mechanism, a fixing rack, a lifting type top layer operation platform, a turning type lower layer operation platform and a retractable type upper layer operation platform, wherein the fixing rack is fixed to the walking mechanism, the lifting type top layer operation platform is arranged in the fixing rack, the turning type lower layer operation platform is provided with a turning mechanism, and the retractable type upper layer operation platform is provided with a retraction mechanism. The operation platforms can be mechanically retracted or lifted, the trolley can mechanically adjust the space operation area in the vertical direction and the horizontal direction of a tunnel and the operation space between the operation platforms, tunnel defect full section improvement station requirements are met, the time for arranging the operation platforms in the defect improvement earlier stage is greatly shortened, and tunnel defect improvement efficiency is improved. The trolley is especially suitable for conducting simultaneous improvement on a tunnel defect full section.

Description

technical field [0001] The invention relates to construction equipment for tunnel disease regulation, in particular to an operation trolley for comprehensive regulation of existing railway tunnel defects. Background technique [0002] When remediating existing railway tunnel defects, since the vault and the arch waist are relatively high from the ground, it is necessary to rely on a relatively high operating platform to rectify tunnel vault defects, and the operating platforms must be distributed along the tunnel section in steps. In order for workers to rectify tunnel arch waist and side wall diseases. However, for the safe operation of the railway, the vehicles running on the existing railway line must meet the operating limit regulations of railway rolling stock, which requires a certain range of variation in the overall size of the trolley to solve the problem of the overall size of the trolley when the tunnel disease is repaired. The contradiction between the requireme...
