Description

Technical Field

[0001] This utility model relates to the field of underground support technology in coal mines, and in particular to a steel strip for equal-strength roadway support. Background Technology

[0002] Mining support steel strips are a common support device used by mining enterprises for roadway and chamber support and landslide reinforcement. With the continuous development of mining technology, the mining depth is increasing and the rock strata through which the roadways pass are becoming more and more complex. In order to ensure the safety of mining production, the demand for the strength and lightweight of support steel strip products is also increasing. Although the existing support steel strip products can provide a certain support strength, the support strength is still limited because the steel strips can only be connected by overlapping anchor rods along the length direction to form a strip support structure, which provides support to the sidewall of the roadway along the length direction. The individual steel strips cannot be directly connected to each other.

[0003] Existing support steel strips lack adequate support structure when used to support roadways, which makes them prone to deformation during support, potentially leading to roadway collapses, roof falls, and other dangerous accidents. To address these issues, a high-strength roadway support steel strip is proposed. Utility Model Content

Two fixing components adapted to the bottom of the steel belt body 1 are provided. Multiple support components are provided at the bottom of the steel belt body 1, including a rectangular steel plate 5 and a U-shaped slider 11. A rectangular groove is formed at the bottom of the steel belt body 1. The rectangular steel plate 5 is fixedly installed in the rectangular groove via an installation unit. A receiving groove is formed on the side of the rectangular steel plate 5. An upper rotating block 7 is rotatably installed on the inner wall of the receiving groove. An upper screw 8 is fixedly installed on the side of the upper rotating block 7. A screw sleeve 9 is threaded onto the upper screw 8. A moving groove is formed at the bottom of the steel belt body 1. The U-shaped slider 11 is slidably installed in the moving groove via a moving unit. A lower rotating block 19 is rotatably installed on the inner wall of the U-shaped slider 11. A lower screw 20 adapted to the screw sleeve 9 is fixedly installed on the side of the lower rotating block 19.

[0023] With the above structure, during installation, the steel strip body 1 is first fixed to the rock mass of the tunnel using the fixing components. Then, the U-shaped slider 11 is moved by the moving unit and adjusted to a suitable position according to the height of the selected rectangular steel plate 5. Then, under the action of the upper rotating block 7 and the lower rotating block 19, the lower screw 20 is aligned with the upper screw 8, and the screw sleeve 9 is rotated so that its threads are installed on the lower screw 20 and the upper screw 8, thereby achieving a stable support function. This setting can improve the stability of the support, play a better protective role, and reduce safety hazards.

[0024] like Figure 1 As shown, the fixing component includes mounting bolts 2. The bottom of the steel belt body 1 is provided with screw holes, and the mounting bolts 2 are threaded into the screw holes. The advantage of this setting is that the steel belt body 1 can be fixed to the top rock wall of the roadway by the setting of mounting bolts 2, which facilitates the installation and disassembly of the steel belt body 1, and the operation is simple and the stability is strong.

[0025] like Figure 1 As shown, the installation unit includes multiple fastening bolts 6. Side plates are fixedly installed on both sides of the rectangular steel plate 5. Multiple threaded holes are opened at the bottom of the two side plates. Multiple threaded grooves are opened at the bottom of the steel strip body 1. Multiple fastening bolts 6 are threaded into the multiple threaded holes and multiple threaded grooves respectively. The advantage of this setting is that the rectangular steel plate 5 can be quickly installed and disassembled by setting multiple fastening bolts 6, which is convenient and easy to operate in practice.

[0026] like Figure 1 As shown, an anti-slip washer 10 is fixedly installed on the outer wall of the screw sleeve 9. The advantage of this setting is that the anti-slip washer 10 can make the screw sleeve 9 more stable when rotating, and prevent the hand from slipping.

[0027] like Figure 2As shown, the moving unit includes a lead screw 12. One end of the lead screw 12 is rotatably mounted on the inner side wall of the moving groove, and the other end of the lead screw 12 extends to the outside of the steel strip body 1 and is fixedly mounted with a knob 13. A U-shaped slider 11 is threaded onto the lead screw 12. A limiting cavity is opened in the steel strip body 1, and a limiting sub-unit adapted to the lead screw 12 is set in the limiting cavity. The advantage of this setting is that, through the setting of the lead screw 12, the U-shaped slider 11 can be driven to move to a suitable position according to the height of the selected rectangular steel plate 5.

The advantage of this arrangement is that, by setting the pressing plate 16, when it comes into contact with the lead screw 12, it can prevent the lead screw 12 from rotating, thus improving stability.

[0029] like Figure 4 As shown, the compression element includes a compression spring 17. One end of the compression spring 17 is fixedly installed on the side of the extrusion plate 16, and the other end of the compression spring 17 is fixedly installed on the side of the partition plate 14. The advantage of this arrangement is that, through the elastic action of the compression spring 17, it is possible to drive the operating plate 18 to achieve the reset extrusion function when the limit on the operating plate 18 is released.

[0030] The working principle of this utility model is as follows: During installation, the main body 1 of the steel strip is first fixed to the rock mass of the tunnel using mounting bolts 2. Then, the sliding operation plate 18 drives the sliding shaft 15 and the extrusion plate 16 to move horizontally in sync, releasing the limit on the lead screw 12. Then, the lead screw 12 is rotated by turning the knob 13, and the U-shaped slider 11 is moved to a suitable position according to the height of the selected rectangular steel plate 5. The operation plate 18 is released, and the extrusion plate 16 is driven to move horizontally and reset under the elastic action of the compression spring 17, thus realizing the limit function of the lead screw 12. Then, under the action of the upper rotating block 7 and the lower rotating block 19, the lower screw 20 is aligned with the upper screw 8, and the screw sleeve 9 is rotated so that its threads are installed on the lower screw 20 and the upper screw 8, realizing the stable support function.
