Description

Technical Field

[0001] This utility model relates to the field of support devices, and in particular to a multi-point connected coal mine mining support device. Background Technology

[0002] Coal mining refers to the process of extracting coal resources buried underground. It is an important part of coal production. Coal mining is divided into open-pit mining and underground mining. Open-pit mining requires stripping the overlying strata before mining the coal seam, while underground mining requires entering the coal seam through shafts and tunnels. Coal mining support devices play a crucial role in coal mining. They are mainly used to keep the roadways open and the surrounding rock stable, which is of great significance for ensuring the safety and efficiency of coal mine production.

[0003] Existing coal mine support devices typically have their top support structure, height adjustment lifting structure, and base connected sequentially from top to bottom. The connection points are relatively simple, and the individual structures themselves, such as two adjacent sets of lifting structures, are usually not connected to each other. Under complex geological conditions or when the support height is high, the stability may be poor, and it is easy to move or fall off, resulting in poor support effect.

[0004] Therefore, existing coal mine support devices typically have a top-to-bottom connection between the top support structure, the lifting structure for height adjustment, and the base. This connection point is relatively simple, and the individual structures themselves, such as adjacent lifting structures, are usually not connected. Under complex geological conditions or at high support heights, stability may be poor, leading to easy movement or detachment and ineffective support. To address this, a system can be installed that can work together to provide multi-directional support to the top and sides of the mine from different angles. This system includes lifting components, top support components, side support components, and support seats. Increasing the connection surfaces with the mine increases stability, and setting up a multi-point connection structure among the components further enhances structural stability. This results in better support of the mine, stronger stability, and greater safety and reliability. Utility Model Content

[0005] To overcome the problem that existing coal mine mining support devices typically have a top support structure, a lifting structure for adjusting height, and a base connected sequentially from top to bottom, with relatively simple connection points, and the individual structures themselves, such as two adjacent lifting structures, are usually not connected to each other, the stability may be poor under complex geological conditions or when the support height is high, and it is easy to move or fall off, resulting in poor support effect.

[0006] The technical solution of this utility model is as follows: a multi-point connected coal mine mining support device, including a support base, a lifting assembly, a top support assembly, a side support assembly, and inserts. The support base is arranged in two sets symmetrically on the left and right. The upper end of each set of support bases is fixedly installed with a lifting assembly for cooperating with each other to control the up and down movement of the top support assembly. The upper end of the lifting assembly is fixedly installed with a top support assembly for supporting the top of the mine. The ends of the two sets of lifting assemblies that are far apart from each other are symmetrically arranged and adjusted to connect with side support assemblies for supporting the sides of the mine. The four corners of the upper end of the support base are surrounded by four sets of inserts for inserting into the ground. The middle of the upper end of the support base is evenly distributed with four sets of inserts for inserting into the ground from front to back. The inserts extend through the upper end of the support base to the lower end. The up and down movement of the inserts is controlled by twisting the upper end of the inserts.

[0007] Preferably, by setting up lifting components, top support components, and side support components that can cooperate with each other to provide multi-directional support to the top and sides of the mine from different angles, as well as support bases for support, the stability of the support can be increased by increasing the connection surface with the mine. Furthermore, by setting each component itself into a multi-point connection structure, the stability of the structure itself can be increased by increasing the number of connection points. This results in better coordination and support effect for the mine, stronger support stability, and greater safety and reliability.

[0008] Preferably, the lifting assembly includes hydraulic rods, hydraulic cylinders, and connecting columns. Five sets of hydraulic cylinders are evenly and fixedly installed along the upper surface of the support base. The upper end of each of the five sets of hydraulic cylinders is provided with a hydraulic rod for vertical movement, and the vertical movement of the hydraulic rod is controlled by the hydraulic cylinders.

[0009] Preferably, each of the two adjacent sets of hydraulic rods is fixedly connected to two sets of connecting columns, and the middle of the connecting column is provided with a connecting hole for adjusting and connecting with the side support assembly.

[0010] Preferably, the top support assembly includes an arc-shaped support plate, a connecting block, a connecting frame, and a first adjusting bolt. Five sets of arc-shaped support plates for supporting the top of the mine tunnel are evenly distributed above the connecting frame. Connecting blocks are provided on the lower sides of both the left and right ends of the arc-shaped support plate. The arc-shaped support plate is made of elastic material.

[0011] Preferably, the connecting block is fixedly connected to the left and right ends of the connecting frame, and the connecting block is adjusted and connected to the arc-shaped support plate by two sets of first adjusting bolts arranged symmetrically. The arc-shaped support plate can be moved up and down by turning the first adjusting bolts.

[0012] Preferably, the side support assembly includes a rectangular support plate and second adjusting bolts. The end of the rectangular support plate near the lifting assembly is adjusted by four sets of second adjusting bolts arranged symmetrically, and the position of the rectangular support plate is adjusted by the second adjusting bolts.

[0013] Preferably, the rectangular support plate has mounting holes around its four corners for further fixing, and the rectangular support plate has through holes evenly distributed linearly on its surface to increase air permeability.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting up lifting components, top support components, and side support components that can work together to provide multi-directional support to the top and sides of the mine from different angles, as well as support bases for support, the stability of the support can be increased by increasing the connection surface with the mine. Furthermore, by setting each component to a multi-point connection structure, the stability of the structure itself can be increased by increasing the number of connection points. This results in better coordinated support for the mine, stronger support stability, and greater safety and reliability. Attached Figure Description

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] See also Figures 1-3This utility model provides an embodiment: a multi-point connected coal mine mining support device, including a support base 1, a lifting assembly, a top support assembly, a side support assembly, and inserts 5. The support base 1 is arranged in two symmetrical sets. The upper ends of the two sets of support base 1 are fixedly installed with lifting assemblies for cooperating with each other to control the up and down movement of the top support assembly. The upper end of the lifting assembly is fixedly installed with a top support assembly for supporting the top of the mine. The ends of the two sets of lifting assemblies that are far apart from each other are symmetrically arranged and adjusted to connect with side support assemblies for supporting the sides of the mine. The four corners of the upper end of the support base 1 are surrounded by four sets of inserts 5 for inserting into the ground. The middle of the upper end of the support base 1 is evenly distributed with four sets of inserts 5 for inserting into the ground from front to back. The inserts 5 extend through the upper end of the support base 1 to the lower end. The up and down movement of the inserts 5 is controlled by twisting the upper end of the inserts 5.

[0024] See also Figure 3 In this embodiment, the lifting assembly includes hydraulic rods 201, hydraulic cylinders 202, and connecting columns 203. Five sets of hydraulic cylinders 202 are evenly and fixedly installed along the upper surface of the support base 1. The upper end of each of the five sets of hydraulic cylinders 202 is provided with a hydraulic rod 201 for vertical movement. The hydraulic rods 201 are controlled to move up and down by the hydraulic cylinders 202. The vertical movement of the hydraulic rods 201 by the hydraulic cylinders 202 can drive the top support assembly to move synchronously to adjust its height. Two sets of connecting columns 203 are fixedly connected between each pair of adjacent sets of hydraulic rods 201. The middle of the connecting column 203 is provided with a connecting hole 204 for adjusting and connecting with the side support assembly. By fixing two sets of connecting columns 203 between each pair of adjacent sets of hydraulic rods 201, the stability of the hydraulic rods 201 can be increased by increasing the connection points between adjacent hydraulic rods 201.

[0025] See also Figure 2 and Figure 4 In this embodiment, the top support assembly includes an arc-shaped support plate 301, a connecting block 302, a connecting frame 303, and first adjusting bolts 304. Five sets of arc-shaped support plates 301 for supporting the top of the mine are evenly distributed above the connecting frame 303. Connecting blocks 302 are provided on the lower sides of both the left and right ends of the arc-shaped support plate 301. The arc-shaped support plate 301 is made of elastic material. The connecting blocks 302 are fixedly connected to the left and right ends of the connecting frame 303. The connecting blocks 302 and the arc-shaped support plate 301 are adjusted and connected by two sets of first adjusting bolts 304 arranged symmetrically. The arc-shaped support plate 301 is moved up and down by turning the first adjusting bolts 304. By setting the top support assembly to consist of multiple sets of arc-shaped support plates 301, the number of connection points between the top support assembly and the top of the mine can be increased. By adjusting and connecting each set of arc-shaped support plates 301 and the connecting frame 303 with two sets of first adjusting bolts 304, the adjustability of the arc-shaped support plates 301 can be increased, and it can also play a further reinforcing role.

[0026] See also Figure 5 In this embodiment, the side support assembly includes a rectangular support plate 401 and a second adjusting bolt 402. The end of the rectangular support plate 401 near the lifting assembly is adjusted and connected by four sets of second adjusting bolts 402 arranged symmetrically. The position of the rectangular support plate 401 is adjusted by the second adjusting bolts 402. The four corners of the surface of the rectangular support plate 401 are provided with mounting holes 403 for further fixing the rectangular support plate 401. The surface of the rectangular support plate 401 is provided with through holes 404 evenly distributed linearly to increase air permeability.

[0027] When working, first take the device to the corresponding position, install and fix the support base 1 on the ground corresponding to the mine, and control the insertion column 5 to move downward by turning the upper end of multiple sets of insertion columns 5 in sequence until all insertion columns 5 are firmly inserted into the ground to form a stable support for the support base 1.

[0028] Then, the top support component is adjusted to the corresponding height according to the actual height of the mine. The height is adjusted by the lifting component, and the hydraulic cylinder 202 controls the hydraulic rod 201 to move up and down, thereby driving the top support component to move synchronously to adjust the height of the top support component, so that the lifting component holds the top support component to support the top of the mine.

[0029] Next, by turning the first adjusting bolt 304, the arc-shaped support plate 301 is moved upward, and the adjusting action of the first adjusting bolt 304 makes the arc-shaped support plate 301 fit more closely with the top surface of the mine.

[0030] Then, the side support components are used to support the two sides of the mine shaft. The rectangular support plate 401 is adjusted to fit against the side of the mine shaft using the second adjusting bolt 402 to support the side.

[0031] The rectangular support plate 401 is further fixed by using the mounting holes 403 on the rectangular support plate 401. The stability of the rectangular support plate 401 is increased by increasing the connection points between the rectangular support plate 401 and the side of the mine tunnel.

[0032] Through the above steps, by setting up lifting components, top support components, and side support components that can cooperate to provide multi-directional support to the top and sides of the mine from different angles, as well as support base 1 for support, the stability of the support can be increased by increasing the connection surface with the mine. By setting each component itself into a multi-point connection structure, the stability of the structure itself can be increased by increasing the connection points. This results in better coordination and support effect for the mine, stronger support stability, and greater safety and reliability. This solves the problem that existing coal mine mining support devices usually have a top-to-bottom sequential connection relationship between the top support structure, the lifting structure for adjusting the height, and the base. The connection points are relatively simple, and the individual structures themselves, such as two adjacent sets of lifting structures, are usually not connected to each other. Under complex geological conditions or when the support height is high, the stability may be poor, and it is easy to move or fall off, resulting in poor support effect.
