Simple maintenance operation platform suitable for various tunnel section forms

Abstract

The invention discloses a simple maintenance operation platform suitable for various tunnel section forms, which is composed of a simple vehicle, a simple portal frame, an operation box body, a supporting structure of the operation box body and a lifting system, and the simple vehicle is composed of a bearing bedplate and six moving wheels in double rows at the bottom; a simple portal frame is arranged in the middle of the bearing table plate, the moving wheels at the bottom are divided into three front and rear rows, the heights of the moving wheels on the left and right sides of each row are fixed, the moving wheel in the middle is a height-adjustable wheel, and brakes are arranged on the two sides of the moving wheels; according to the simple maintenance work platform, maintenance work in a tunnel can be carried out under the condition of various tunnel section forms. The whole lifting operation platform is built through a split type structure of the simple vehicle and the lifting operation box body, the problems of safety, applicability, movement and the like of the operation platform are reasonably solved, and a safe and efficient working condition is provided for maintenance work in a tunnel.

Description

technical field [0001] The invention relates to the technical field of maintenance platforms, in particular to a simple maintenance operation platform suitable for various tunnel section forms. Background technique [0002] After the subway shield tunnel is opened from the section, there are often various problems that need to be repaired. For example, problems such as water leakage, partial damage, collapse and lining cracking of the segment of the tunnel occur from time to time. The staff responsible for maintenance needs to use corresponding technical means to plug and repair such faults. However, during the maintenance operation for the upper and middle parts of the tunnel, the staff simply used scaffolding, ladders, steel plates and other materials to simply build a working platform according to the tunnel section form and ground support at the construction site. The work platform of the high-end work platform often has the problem of unstable lower support. At the sa...

AI Technical Summary

Problems solved by technology

However, during the maintenance work at the higher position in the middle and upper part of the tunnel, the staff only used materials such as scaffolding, ladders and steel plates to simply build a working platform according to the tunnel section form and ground support conditions at the construction site. The working platform often has the problem of unstable lower support

At the same time, because the connection between the various components of the platform is not firm and there is no safety rope to fix the position, safety accidents such as falling from high places are very prone to occur. In addition, the working area of ​​the platform is very limited, and it cannot be moved or lifted. Replace the maintenance point Need to re-platform

This kind of temporary operation platform not only cannot cover all the maintenance points of a certain section of the tunnel, but also cannot realize the rapid replacement of the tunnel maintenance section, which makes the entire maintenance work inefficient and seriously affects the progress of the subsequent projects.

[0003] At present, the tunnel repair and maintenance construction process lacks a safe, reliable, widely applicable, and easy-to-move liftable work platform. In the prior art, workers usually use single-layer or multi-layer scaffolding, ladders, steel plates and other materials according to the tunnel section at the construction point. Form and ground support are simple to build an operation platform. The connection between the various structures of the operation platform is not firm and there is no safety rope to fix the position, so safety accidents such as falling from high places are very easy to occur. At the same time, this simple operation platform still has work The shortcomings of small area, non-movable and non-lifting make the operation process very inconvenient
