[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0022] The present application provides a step-through platform for underground on-site construction, which is mainly used to solve the problem that some areas inside the coal mine may be laid with pipelines and other equipment, which makes it inconvenient for construction workers to walk and poses a great safety hazard, and provides the following technical solutions. Figure 1-Figure 4 Make a detailed description:

[0023] A step-through platform for underground on-site construction mainly comprises two L-shaped support frames 1 and a connecting plate 2. The two support frames 1 are symmetrically arranged. The support frame 1 comprises a horizontally arranged load-bearing plate 11 and a support plate 12 fixed at one end of the load-bearing plate 11. The load-bearing plate 11 is provided with a slot 13 at one end facing away from the support plate 12. The two opposite sides of the connecting plate 2 are respectively movably inserted in the two slots 13. The bottom end of the support plate 12 is provided with an extension slot 14. An extension plate 15 is movably inserted in the extension slot 14. The support plate 12 is provided with a fixing piece 16 for fixing the extension plate 15. When the device is installed and used, first, the connecting plate 11 is connected to the support plate 12. The two sides of the connecting plate 2 are inserted into the slots 13 on the two bearing plates 11, and the extension plate 15 is inserted into the extension slot 14. The distance between the two support frames 1 and the height of the support frames 1 are adjusted according to actual conditions. Then the two support frames 1 are symmetrically placed at predetermined positions in the underground construction area. Multiple such devices can form a platform to facilitate the movement of construction personnel and reduce safety hazards. In another modified plan, the connecting plate 2 is movably inserted in the slot 13, providing flexibility to adapt to underground spaces of different widths. The extension plate 15 can adjust its length according to actual needs, and with the use of fixings 16, the platform can adapt to different height requirements.

[0024] For details, please refer to Figure 2 , Figure 3 and Figure 4 A plurality of fixed grooves 151 distributed in an array are constructed on one side of the extension plate 15 along the length direction, providing a plurality of optional fixing positions for the fixing member 16. The fixing member 16 includes a fixing nail 161 threadedly inserted on the support plate 12, ensuring good stability and connection strength between the fixing nail 161 and the support plate 12. One end of the fixing nail 161 is movably inserted into the interior of one of the fixing grooves 151. According to actual needs, the extension plate 15 is placed in a suitable position, and then one end of the fixing nail 161 is movably inserted into a fixing groove 151 on the extension plate 15. A fixing knob 162 is fixed to the other end of the fixing nail 161. The fixing knob 162 is used to rotate the fixing nail 161, and the fixing knob 162 can be tightened to ensure the stable fixation of the extension plate 15 on the support plate 12. In this solution, the array distribution of the fixing grooves 151 provides multiple fixing points, so that the extension plate 15 can be fixed in multiple positions, which increases the adaptability and flexibility of the platform. The design of the fixing knob 162 makes the fixing and adjustment of the extension plate 15 simple and quick, and the operator can quickly adjust the position of the extension plate 15 to adapt to different construction requirements.

[0025] To ensure the stability of the device, refer to Figure 2 and Figure 4 A horizontally arranged pad 152 is fixed to the bottom end of the extension plate 15. The horizontal arrangement of the pad 152 provides a stable bottom surface for the extension plate 15, thereby increasing the stability of the entire structure. The pad 152 can disperse the load on the extension plate 15, reduce the pressure on the support plate 12, and improve the bearing capacity.

[0026] In this example, see Figure 2 and Figure 3 The bottom side of the connecting plate 2 is constructed with a plurality of positioning grooves 21 distributed in an array along the length direction. A positioning pin 111 is threadedly inserted into the bottom of the carrying plate 11. One end of the positioning pin 111 is movably inserted into one of the positioning grooves 21. A positioning knob 112 is fixed to the other end of the positioning pin 111. By rotating the positioning knob 112, the depth of the positioning pin 111 can be adjusted to ensure that the positioning pin 111 is stably inserted into the positioning groove 21. The design of the positioning knob 112 simplifies the fixing process of the positioning pin 111, so that non-professionals can also operate it conveniently. The array distribution of the positioning grooves 21 provides a plurality of optional positioning points, so that the carrying plate 11 can be adjusted according to different needs.

[0027] For further information, see Figure 2 , Figure 3 and Figure 4 A reinforcing rod 17 is connected between the load-bearing plate 11 and the connected support plate 12. The reinforcing rod 17 significantly improves the stability of the connection between the load-bearing plate 11 and the support plate 12, and reduces the deformation or bending of the structure under load. By using the reinforcing rod 17, the load-bearing capacity of the entire platform is improved, and more weight can be safely supported. The reinforcing rod 17 helps to more evenly distribute the load on the load-bearing plate 11 to the support plate 12, thereby improving the load distribution of the entire structure.

[0028] Furthermore, anti-slip grooves are provided on the top side of the load-bearing plate 11. The presence of the anti-slip grooves significantly reduces the risk of construction workers slipping on the load-bearing plate 11, especially in a humid or debris environment. By reducing the risk of slipping accidents, the anti-slip grooves help reduce work-related accidents and protect the health of construction workers.

[0029] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
