Description

Technical Field

[0001] The utility model relates to the technical field of mine mining support, in particular to a mine support and protection component. Background Technique

[0002] A mine is a workplace for underground resource mining, with complex geological conditions and various safety risks. During the mining process, it is necessary to effectively support and protect the surrounding rock and roof of the mine to prevent accidents such as roof collapse and surrounding rock deformation, and to ensure the safety of miners and the normal operation of equipment. However, the current traditional support components have poor adaptability: the size and shape of the mine are not completely fixed and may vary in different areas or mining stages. However, traditional support and protection components often have a relatively fixed structure and are difficult to adapt to various different sizes and shapes of the mine, resulting in poor support effects in some special parts. At the same time, installation and disassembly are difficult. The complex structural design may make the installation and disassembly process of the support components in the mine time-consuming and laborious, affecting the efficiency of mining work and increasing the labor intensity of workers. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problems in the background technique and propose a mine support and protection component.

[0004] To achieve the above purpose, the utility model adopts the following technical scheme:

[0005] A mine support and protection component includes a plurality of symmetrically arranged base frames. An installation seat is installed at the lower end of each base frame. A plurality of installation holes are symmetrically opened on each installation seat. A support steel is installed in each base frame. A horizontal base is installed at the upper end of each support steel. A T-shaped steel is jointly installed on two adjacent horizontal bases. An extension steel is installed in the two T-shaped steels corresponding in position.

[0006] The T-shaped steel includes a connecting steel, and the connecting steel is installed on two adjacent horizontal bases. A transverse steel is installed on the side wall of the connecting steel, and the extension steel is installed in the two transverse steels corresponding in position.

[0007] Preferably, two limiting grooves are symmetrically opened on the outer side wall of the base frame. The support steel is slidably connected in the base frame. Two locking screws are symmetrically installed on the outer side wall of the support steel. Each locking screw passes through the limiting groove and is threadedly connected with a locking nut.

[0008] Preferably, a positioning block is slidably connected to the lower surface of each horizontal base, and the positioning block is clamped on the upper end of the corresponding support steel. The support steel and the positioning block are connected by a first locking stud.

[0009] Preferably, a T-shaped chute is provided on the lower surface of each of the horizontal bases, and a T-shaped slider is fixedly connected to the upper end of the positioning block, and the T-shaped slider is slidably connected in the T-shaped chute.

[0010] Preferably, sliding strips are symmetrically provided on the inner side walls of each of the connecting steels, limiting chutes are provided on both side walls of each of the horizontal bases, and each sliding strip is slidably connected in the correspondingly positioned limiting chute, and the connecting steel and the horizontal base are locked by a second locking stud.

[0011] Preferably, the transverse steel and the extension steel are locked by a third locking stud.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. The length of the base frame and the support steel in the vertical direction can be adjusted, which is convenient for adjusting the overall height of the device, improving the breadth of the device adaptation, and achieving the same support effect without setting a large number of connecting supports for mines with different heights. The more overlapping positions between the base frame and the support steel, the stronger the support ability. Accordingly, the number of the base frame and the support steel can be reduced and reasonably adjusted.

[0014] 2. The positioning block and the first locking stud realize the connection between the support steel and the horizontal base, preparing for the connection between the horizontal base and the T-shaped steel. The connection between the connecting steel and the horizontal base realizes the adjustable length in the Y-axis upward direction, which is suitable for installation with different distances between different base frames, improving the breadth of the device adaptation. The setting of the transverse steel and the extension steel realizes the adjustable length in the X-axis upward direction, which is applicable to mines with different widths within a certain range. The connection between the connecting steel and the horizontal base can also realize the adjustment of the distance between adjacent transverse steel and extension steel.

[0015] In summary, the structure of the present utility model is ingenious, applicable to mines with different specifications within a certain range. At the same time, for different mine conditions (such as different soil qualities), or different mining stages of the same mine, reasonable adjustments can be made to adapt to different sizes and shapes of the mine.

Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Refer to Figures 1-4 , a mine support and protection component, including a plurality of symmetrically arranged base frames 1. An installation seat 15 is installed at the lower end of each base frame 1, and a plurality of installation holes 16 are symmetrically opened on each installation seat 15. A support steel 2 is installed in each base frame 1. Two limit grooves 7 are symmetrically opened on the outer side wall of the base frame 1. The support steel 2 is slidably connected in the base frame 1. Two locking screws are symmetrically installed on the outer side wall of the support steel 2. Each locking screw passes through the limit groove 7 and is threadedly connected with a locking nut 8. The length of the base frame 1 and the support steel 2 in the vertical direction can be adjusted, so as to cope with mines of different heights. The more the overlapping positions of the base frame 1 and the support steel 2, the stronger the support capacity. Correspondingly, the number of the base frame 1 and the support steel 2 can be reduced and adjusted reasonably;

[0023] A horizontal base 3 is installed at the upper end of each support steel 2. A positioning block 10 is slidably connected to the lower surface of each horizontal base 3, and the positioning block 10 is clamped at the upper end of the corresponding support steel 2. The support steel 2 and the positioning block 10 are connected by a first locking stud 14. A T-shaped sliding groove 11 is opened on the lower surface of each horizontal base 3. The upper end of the positioning block 10 is fixedly connected with a T-shaped slider, and the T-shaped slider is slidably connected in the T-shaped sliding groove 11. The positioning block 10 is slidably connected with the horizontal base 3. According to different loading conditions, when the mine specifications change at different mining stages in the same mine, the number of the base frame 1 and the support steel 2 can be added correspondingly. After the addition, the installation of the horizontal base 3, the T-shaped steel and the extension steel is carried out. After the installation is completed, the positions of the previously installed horizontal base 3, the T-shaped steel and the extension steel can be reasonably adjusted.

[0024] Two adjacent horizontal bases 3 are jointly installed with T-shaped steels, and an extension steel 6 is installed in two T-shaped steels with corresponding positions; the T-shaped steel includes a connecting steel 4, and the connecting steel 4 is installed on two adjacent horizontal bases 3. Slide bars 9 are symmetrically arranged on the inner side walls of each connecting steel 4, and limit sliding grooves 12 are opened on both side walls of each horizontal base 3, and each slide bar 9 is slidably connected in the corresponding limit sliding groove 12. The connecting steel 4 and the horizontal base 3 are locked by a second locking stud 13. A transverse steel 5 is installed on the side wall of the connecting steel 4, and the extension steel 6 is installed in two corresponding transverse steels 5. The transverse steel 5 and the extension steel 6 are locked by a third locking stud.

[0025] When the utility model is installed, first, the base frame 1 is fixed to the foundation in sequence according to the planning of the mine and the load-bearing situation. The base frame 1 is fixed by fixing ground nails through the installation holes 16 on the mounting seat 15. Subsequently, the height of the support steel 2 is adjusted. The support steel 2 slides in the base frame 1 and stops when it reaches the required height, and then the locking nut 8 is tightened to fix the height of the support steel 2. Subsequently, the positioning blocks 10 are sequentially clamped on the upper end of the support steel 2 and fixed to the support steel 2 by the first locking studs 14, so as to install the horizontal base 3 on the support steel 2. Then, the two T-shaped steels and the extension steel 6 are assembled and installed to adjust the total length of the T-shaped steels and the extension steel 6, ensuring that the total length of the T-shaped steels and the extension steel 6 is equal to the distance between two base frames 1 with corresponding positions. Then, when installing the combination of the T-shaped steels and the extension steel 6, when installing the T-shaped steel, the connecting steel 4 is slid between two adjacent horizontal bases 3, and after moving to a suitable position, it is locked by the second locking stud 13. After the second locking stud 13 locks and fixes the horizontal base 3 and the connecting steel 4, the extension steel 6 and the transverse steel 5 are locked and fixed by the third locking stud.

[0026] The above is only the preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the utility model, according to the technical solution of the utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the utility model.
