Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of scaffold for railway tunnel maintenance is provided.
The purpose of this utility model can be achieved through the following technical solutions:
For a scaffold for railway tunnel maintenance, comprise;
Scaffold main body;
Also comprise:
Scaffold base, is provided with four rollers coordinated with rail, removably connects with scaffold main body bottom it, for scaffold main body is fixed on rail.
Described scaffold base comprises four legs, and for connecting the connecting rod of four legs, described four rolling is located on four legs respectively.
Described leg comprises:
Matrix, is connected with connecting rod;
Support, is located at above matrix, for connecting pin hand cradle main body;
Roller fixed mechanism, is located at below matrix, for installing roller;
Braking mechanism, be located at below matrix, stops it to rotate for fastening roller.
Described roller fixed mechanism comprises roller shaft and bearing, and described roller shaft is located on matrix, and described roller housing is located on roller shaft, and described bearing is located between roller shaft and roller.
Described roller is provided with spoke hole,
Described braking mechanism comprises:
Brake cover, is fixed on matrix;
Brake axle, axial activity is located in brake cover, for inserting in the spoke hole of roller, and then stops roller to rotate.
Described scaffold main body is provided with staircase.
Compared with prior art, the utility model has the following advantages:
1) scaffold base is provided with four rollers coordinated with rail, the overall movement automatically on rail of scaffold can be realized, conveniently moving, mobility strong, for tunnel maintenance provides conveniently, especially for the maintenance of tunnel roof and sidewall provides conveniently, the efficiency of railway tunnel maintenance is substantially increased.
2) because the connected mode between scaffold base and scaffold main body is for removably connecting, the scaffold main body that therefore scaffold base of the present utility model can be suitable with arbitrary size is connected, compatible good, applied widely.
3) braking mechanism can make scaffold stop on rail, so that construction operation.
