[0002] According to the production needs of the mine, the transportation team recently carried out ceiling plastering construction in the pedestrian inclined tunnel. The top of the tunnel was a certain distance from the ground, and the staff were required to set up a construction platform on site to facilitate the ceiling plastering construction. Since the tunnel was distributed in an inclined shape, if a construction platform was set up underground, its stability could not be guaranteed, and there were certain safety hazards. Utility Model Content

[0003] The technical problem to be solved by the utility model is: to overcome the shortcomings of the prior art and provide a mobile construction platform for the inclined tunnel in a coal mine. By arranging side bars and inclined bars at both ends of a load-bearing beam and laying wooden boards on the load-bearing beam, a construction platform is formed, which is conducive to the staff to carry out ceiling plastering construction.

[0004] The technical solution adopted by the utility model to solve the technical problem is:

[0005] A mobile construction platform for an inclined tunnel in an underground coal mine comprises a load-bearing beam, a side rod and an inclined rod. There are two load-bearing beams, and a side rod is fixedly connected to the left end of each load-bearing beam, and a diagonal rod is fixedly connected to the right end of each load-bearing beam. The tops of the side rods and the diagonal rods are respectively connected to rope grippers by bolts, and the rope grippers are arranged on the tunnel wire rope. Blocking clips are arranged at intervals on the load-bearing beam, and wooden boards are arranged between the blocking clips.

[0006] The included angle between the side rod and the load-bearing beam is 90°, the included angle between the diagonal rod and the load-bearing beam is 135°, and the height of the side rod is greater than that of the diagonal rod.

[0007] There are at least two blocking cards, both of which are distributed in an L shape.

[0008] The outer walls of the side rods and the oblique rods are respectively provided with positioning sleeves, and a positioning inserting frame is provided between the left and right adjacent positioning sleeves.

[0009] The positioning brackets are distributed in a U-shape.

[0010] The positive beneficial effects of the utility model are:

[0011] 1. The utility model arranges positioning sleeves on the outer walls of the side bars and the oblique bars respectively, and inserts positioning brackets between the left and right adjacent positioning sleeves, thereby avoiding the outward movement of the two load-bearing beams during construction, thereby ensuring the stability and safety of the construction.

[0012] 2. The utility model has barrier clips arranged at intervals on the load-bearing beam to play a role of limiting, thereby preventing the wooden board from moving on the load-bearing beam due to the influence of the inclined tunnel; by setting up this device, the problem of difficult platform erection during the high-altitude construction of the inclined tunnel is effectively solved, the safety of the workers is guaranteed, and the construction period is shortened.
