Description

Technical Field

[0001] The utility model belongs to the technical field of underground equipment and relates to a detachable steel pipe support operating platform for underground ramp repair operations. Background Art

[0002] The metal mine tunnel repair project is one of the most important projects in the mining and production of metal and non-metallic ores. Its main contents include restoring the original tunnel design section; clearing the silt and water in the tunnel and adjusting the tunnel slope, cleaning the floating gangue and other debris; repairing the ditch and treating the tunnel bottom; and restoring the tunnel that has collapsed or collapsed. At present, the socket-type disc buckle scaffolding is used as the construction platform for the repair of the tunnel arch in Jinchuan Mine. It has a simple structure and is easy to assemble and disassemble, but its safety factor is low. It is only suitable for construction on relatively simple terrain and flat bottom plates. When used for repairing ramps, the scaffolding is tilted as a whole and the structure is unstable, making it difficult to withstand the counter-impact force during operation. At the same time, in order to cooperate with the waste rock shoveling and other operations of vehicles such as forklifts, the scaffolding needs to be moved frequently, reducing construction efficiency. Utility Model Content

[0003] The purpose of the utility model is to address the problems existing in the prior art and provide a detachable steel pipe support work platform for underground ramp repair operations, which solves the problems of low safety factor and unstable structure of the existing socket-type disc buckle scaffolding as a construction platform, and the need to frequently move the scaffolding to cooperate with operations such as waste rock shoveling by vehicles such as forklifts, resulting in reduced construction efficiency.

[0004] To this end, the present invention adopts the following technical solutions:

[0005] A detachable steel pipe support work platform for underground ramp repair work, comprising a first layer of steel mesh and a second layer of steel mesh arranged in parallel, the first layer of steel mesh being provided with four first-row cross bars around its periphery, a plurality of first-row vertical bars being provided at the bottom of the first row of cross bars, and the second layer of steel mesh being provided with four second-row cross bars around its periphery, the first row of vertical bars being fixedly connected to the second row of cross bars;

[0006] The upper edge of the second row of cross bars is surrounded by a square platform fence, and a plurality of third and fourth row cross bars are arranged in parallel at the bottom. The second and third row cross bars are connected by a plurality of vertically arranged second row vertical bars. A diagonal brace is provided between the second row of cross bars and the second row of vertical bars. The third and fourth row cross bars are connected by a plurality of vertically arranged third row vertical bars, and the bottom of the third row of vertical bars is provided with retractable legs.

[0007] Furthermore, the area of ​​the first layer of steel mesh is smaller than the area of ​​the second layer of steel mesh.

[0008] Furthermore, one end of the diagonal brace is connected to the second row of horizontal bars, and the other end is connected to the second row of vertical bars.

[0009] Furthermore, the first row of vertical poles, the third row of horizontal poles, the third row of vertical poles and the fourth row of horizontal poles are all made of two steel pipes connected by connecting flanges.

[0010] The beneficial effects of the present invention are:

[0011] The utility model has the characteristics of good stability and high safety factor, which reduces the safety risks of workers working at height. When performing underground construction, construction vehicles such as scrapers can operate under the working platform, avoiding the shortcomings of traditional socket-type disc buckle scaffolding that requires frequent moving and disassembly, thereby improving construction efficiency.
