Description

Technical Field

[0001] This utility model relates to the field of support structure technology, specifically a coal mine mining support structure. Background Technology

[0002] Coal mining refers to the process of extracting underground coal resources through manpower, machinery, and other means. Its main purpose is to obtain coal resources, provide energy for the national economy, and meet the coal needs of various sectors such as industry, agriculture, and commerce. Coal mining operations require working deep underground, and the working environment is relatively harsh. If the support structure is not solid, it is easy to collapse. Therefore, it is necessary to protect the safety of workers. In order to prevent the collapse of the underground working environment, a coal mining support structure is proposed.

[0003] For example, a coal mine mining support structure disclosed in the authorization announcement number CN221838378U includes a left bottom plate, a lower extension plate slidably connected inside the left bottom plate, a right bottom plate fixedly connected to the upper end of the lower extension plate, a motor box fixedly connected to the lower surface of the left bottom plate, a servo motor fixedly connected inside the motor box, a transmission rod splinedly connected to one end of the servo motor, a rotating column fixedly connected to one end of the transmission rod, and a lifting column slidably connected to one end of the rotating column.

[0004] Although it achieves the setting of the left bottom plate and the lower extension plate, it can shrink the entire support structure according to the working environment of coal mining during use, which plays an extension role. Through the setting of servo motor and telescopic plate, the rotation of servo motor drives the rotation of rotating column, so that the lifting column moves up and down, and the height of telescopic plate is adjusted, which plays the role of adjusting height.

[0005] However, this does not solve the problem that the existing support structure is not conducive to convenient linkage opening and closing for protection of the tunnel top, nor is it conducive to flexible adjustment of the protection position, thus affecting the protection effect and the flexibility of use. Utility Model Content

[0006] The purpose of this utility model is to provide a coal mine mining support structure to solve the problems mentioned in the background art, such as the inconvenience of easy linkage opening and closing of the support structure to protect the top of the tunnel, the difficulty in flexibly adjusting the protection position, and the impact on the protection effect and the flexibility of use.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A coal mine mining support structure includes a bearing seat and a tilting seat. The tilting seat is arranged above the bearing seat. A movable shaft is installed on the side of the tilting seat near the bearing seat, and the tilting seat is movably connected to the bearing seat through the movable shaft. Tilting hydraulic cylinders are symmetrically arranged on the outer wall of the bearing seat, and the tilting hydraulic cylinders are movably connected to the bearing seat. A tilting push arm is installed at the output end of each tilting hydraulic cylinder.

[0009] Optionally, each of the flip push arms is equipped with a pin at one end near the flip base, and the flip push arm is movably connected to the flip base via the pin.

[0010] Optionally, a support base is installed at the top of the flip base, and the support base is fixedly connected to the flip base.

[0011] Optionally, two sets of lifting hydraulic cylinders are symmetrically installed at the top of the support base, and the lifting hydraulic cylinders are fixedly connected to the support base.

[0012] Optionally, each of the lifting hydraulic cylinders is equipped with a lifting push arm at its output end, and a support frame is provided above the support base, with the support frame fixedly connected to the lifting push arm.

[0013] Optionally, adjustment frames are provided on both sides of the support frame, and a linkage shaft is installed on the side of the adjustment frame closest to the support frame, and the adjustment frame is movably connected to the support frame through the linkage shaft.

[0014] Optionally, two sets of adjusting hydraulic cylinders are symmetrically arranged at the bottom end of the support frame, and the adjusting hydraulic cylinders are movably connected to the support frame.

[0015] Optionally, each of the adjusting hydraulic cylinders is equipped with an adjusting push arm at its output end, and each adjusting push arm is equipped with a hinge shaft at the end near the adjusting frame, and the adjusting push arm is movably connected to the adjusting frame through the hinge shaft.

[0016] Optionally, a main support arc plate is installed at the top of the support frame, and the main support arc plate is fixedly connected to the support frame.

[0017] Optionally, each side wall of the adjustment frame is equipped with a secondary support arc plate, and the secondary support arc plate is fixedly connected to the adjustment frame.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the support structure not only realizes convenient linkage opening and closing to protect the top of the tunnel and facilitates flexible adjustment of the protection position, but also improves the protection effect and the flexibility of use.

[0019] The structure is placed inside a coal mine tunnel. A lifting hydraulic cylinder drives a lifting push arm upwards, which in turn moves a support frame and an adjusting frame upwards. The support frame then moves the main support arc plate upwards until it contacts the tunnel top. An adjusting hydraulic cylinder drives an adjusting push arm, which, via a hinge shaft, rotates the adjusting frame around a linkage shaft. The adjusting frame then rotates the secondary support arc plate to both sides of the main support arc plate. The two sets of secondary and main support arc plates form an arc-shaped dome. Under the continuous action of the lifting hydraulic cylinder, the arc-shaped dome contacts the tunnel top. Because the arc-shaped dome can effectively withstand external pressure, it provides excellent support for the tunnel top, thus ensuring the safety of workers. This system allows for convenient linkage opening and closing to protect the tunnel top, improving the protective effect.

[0020] When protection of the side tunnel is required, the tilting hydraulic cylinder drives the tilting push arm to move. Supported by the bearing seat, the tilting push arm drives the tilting seat to rotate around the movable shaft via the pin. The tilting seat drives the support seat, support frame, adjustment frame, main support arc plate and secondary support arc plate to rotate, so that the main support arc plate and secondary support arc plate rotate to the top of the side tunnel, thereby protecting the side tunnel. This facilitates flexible adjustment of the protection position and improves the flexibility of use. Attached Figure Description

[0035] Please refer to the figure. Figure 5 This utility model provides an embodiment of a coal mine mining support structure, including a bearing seat 5 and a tilting seat 6. The tilting seat 6 is arranged above the bearing seat 5. A movable shaft 17 is installed on the side of the tilting seat 6 near the bearing seat 5, and the tilting seat 6 is movably connected to the bearing seat 5 through the movable shaft 17. Tilting hydraulic cylinders 14 are symmetrically arranged on the outer wall of the bearing seat 5. The tilting hydraulic cylinders 14 play a power driving role and are movably connected to the bearing seat 5. A tilting push arm 15 is installed at the output end of each tilting hydraulic cylinder 14. A pin 16 is installed at the end of each tilting push arm 15 near the tilting seat 6, and the tilting push arm 15 is movably connected to the tilting seat 6 through the pin 16. A support seat 1 is installed at the top of the tilting seat 6, and the support seat 1 is fixedly connected to the tilting seat 6.

[0036] The structure is placed inside a coal mine tunnel. The lifting hydraulic cylinder 7 is opened, causing the lifting push arm 8 to move upwards. The lifting push arm 8 then moves the support frame 2 and the adjusting frame 9 upwards. The support frame 2 moves the main support arc plate 3 upwards until it contacts the top of the tunnel. Then, the adjusting hydraulic cylinder 10 is opened, causing the adjusting push arm 11 to move. The adjusting push arm 11, through the hinge shaft 12, drives the adjusting frame 9 to rotate around the linkage shaft 13. The adjusting frame 9 then rotates the secondary support arc plate 4 to both sides of the main support arc plate 3. The two sets of secondary support arc plates 4 and the main support arc plate 3 form an arc-shaped dome. Under the continuous action of the lifting hydraulic cylinder 7, the arc-shaped dome contacts the top of the tunnel. Because the arc-shaped dome can effectively withstand external pressure, it provides good support for the top of the tunnel, thus ensuring the safety of workers. This convenient linkage opening and closing mechanism protects the top of the tunnel and improves the protective effect.

[0037] Two sets of lifting hydraulic cylinders 7 are symmetrically installed on the top of the support base 1. The lifting hydraulic cylinders 7 play a power driving role and are fixedly connected to the support base 1.

[0038] The output end of the lifting hydraulic cylinder 7 is equipped with a lifting push arm 8. A support frame 2 is provided above the support base 1, and the support frame 2 is fixedly connected to the lifting push arm 8. Adjustment frames 9 are provided on both sides of the support frame 2, and a linkage shaft 13 is installed on the side of the adjustment frame 9 closest to the support frame 2. The adjustment frame 9 is movably connected to the support frame 2 through the linkage shaft 13.

[0039] Two sets of adjusting hydraulic cylinders 10 are symmetrically arranged at the bottom end of the support frame 2. The adjusting hydraulic cylinders 10 play a power driving role and are movably connected to the support frame 2.

[0040] Each hydraulic cylinder 10 has an adjusting push arm 11 installed at its output end. Each adjusting push arm 11 has a hinge shaft 12 installed at the end near the adjusting frame 9. The adjusting push arm 11 is movably connected to the adjusting frame 9 through the hinge shaft 12.

[0041] The top of the support frame 2 is equipped with a main support arc plate 3, and the main support arc plate 3 is fixedly connected to the support frame 2. The side walls of the adjustment frame 9 are equipped with secondary support arc plates 4, and the secondary support arc plates 4 are fixedly connected to the adjustment frame 9.

[0042] When protection of the side tunnel is required, the tilting hydraulic cylinder 14 is opened, which drives the tilting push arm 15 to move. Under the support of the bearing seat 5, the tilting push arm 15 drives the tilting seat 6 to rotate around the movable shaft 17 via the pin shaft 16. The tilting seat 6 drives the support seat 1, support frame 2, adjustment frame 9, main support arc plate 3 and secondary support arc plate 4 to rotate, so that the main support arc plate 3 and secondary support arc plate 4 rotate to the top of the side tunnel, thereby protecting the side tunnel. This facilitates flexible adjustment of the protection position and improves the flexibility of use.

[0043] Working principle of the technical solution provided by this utility model:

[0044] First, the structure is placed inside the coal mine tunnel. The lifting hydraulic cylinder 7 drives the lifting push arm 8 upwards, which in turn moves the support frame 2 and adjusting frame 9 upwards. The support frame 2 then moves the main support arc plate 3 upwards until it contacts the tunnel top. The adjusting hydraulic cylinder 10 drives the adjusting push arm 11 to move, which, via the hinge shaft 12, drives the adjusting frame 9 to rotate around the linkage shaft 13. The adjusting frame 9 then rotates the secondary support arc plate 4 to both sides of the main support arc plate 3. The two sets of secondary support arc plates 4 and the main support arc plate 3 form an arc-shaped dome. Under the continuous action of the lifting hydraulic cylinder 7, the arc-shaped dome contacts the tunnel top. Because the arc-shaped dome can... With its excellent ability to withstand external pressure, it can provide good support for the top of the tunnel, thereby ensuring the safety of the workers. When it is necessary to protect the tunnel on the side, the tilting hydraulic cylinder 14 drives the tilting push arm 15 to move. The tilting push arm 15 drives the tilting seat 6 to rotate around the movable shaft 17 via the pin shaft 16. The tilting seat 6 drives the support seat 1, support frame 2, adjustment frame 9, main support arc plate 3 and secondary support arc plate 4 to rotate, so that the main support arc plate 3 and secondary support arc plate 4 rotate to the top of the tunnel on the side, thereby protecting the tunnel on the side and better adjusting the protection. The above is the complete usage of the coal mine mining support structure.

To provide the public with a thorough understanding of this utility model, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand this utility model even without these detailed descriptions.
