[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] like Figures 1 to 6 As shown, the present invention provides a support structure comprising a support plate 11, a support assembly 20, and a connecting assembly 30. The support plate 11 is configured to connect to a mobile support 10. Multiple support assemblies 20 are spaced apart on the support plate 11 to support the roof. The connecting assembly 30 is disposed between two adjacent support assemblies 20 to connect them.

[0046] According to the technical solution of the present invention, the pillar device includes a support plate 11, multiple support assemblies 20 and a connecting assembly 30. The support plate 11 is connected to the mobile bracket 10, and the mobile bracket 10 can drive the support plate 11 to move, thereby achieving the purpose of flexible support. The multiple support assemblies 20 are evenly spaced on the support plate 11 to ensure the center of gravity of the support plate 11 while effectively supporting the working surface. The multiple support assemblies 20 are connected by the connecting assembly 30, which improves the stability of the support. When in use, the support plate 11 is connected to the mobile bracket 10, and the multiple support assemblies 20 are activated so that their tops rise to support the top of the working surface and support the working surface; when the support assembly 20 needs to be transferred, the support assembly 20 is controlled to shorten so that its top is separated from the top of the tunnel, and then the mobile bracket 10 is controlled to move, driving the support plate 11 and the support assembly 20 thereon to move as a whole, thereby realizing the self-movement of the support assembly 20, eliminating the need for manual handling, reducing the labor intensity of workers, and improving work safety.

[0047] like Figure 2As shown, the support assembly 20 includes a pillar 21, a mounting seat 22, and a support block 23. The mounting seat 22 and the support block 23 are detachably connected by fasteners 24. The mounting seat 22 is disposed on the support plate 11, and the pillar 21 is inserted into the support block 23. In this embodiment, the support assembly 20 includes the pillar 21, the mounting seat 22, and the support block 23. The mounting seat 22 is disposed on the support plate 11 and is detachably connected to the support block 23 using fasteners 24, thereby limiting and fastening the pillar 21 inserted into the support block 23. The use of fasteners 24 not only makes the support assembly 20 easy to disassemble and assemble, thereby improving the flexibility of on-site operations, but also ensures the stability of the pillar 21 during movement with the support plate 11 by connecting the pillar 21 to the support block 23. The support block 23 is provided with a support hole 232, which is internally threaded. The pillar 21 is threadedly connected to the support hole 232 and inserted into the support hole 232.

[0048] Furthermore, the mounting seat 22 has a base plate 221, a first side wall 222 and a second side wall 223, the first side wall 222 and the second side wall 223 are respectively arranged at both ends of the base plate 221, the base plate 221, the first side wall 222 and the second side wall 223 cooperate to form a mounting groove 220, the support block 23 is located in the mounting groove 220, a first through hole 2221 is provided on the first side wall 222, a second through hole 2231 is provided on the second side wall 223, a third through hole 231 is provided on the support block 23, the first through hole 2221, the second through hole 2231 and the third through hole 231 are arranged in a one-to-one correspondence, and the third through hole 231 cooperates with the first through hole 2221 and the second through hole 2231 through a fastener 24 to realize a detachable connection between the mounting seat 22 and the support block 23.

[0049] In this embodiment, the mounting base 22 includes a base plate 221, a first side wall 222, and a second side wall 223. The base plate 221, the first side wall 222, and the second side wall 223 cooperate to form a concave mounting groove 220. The shape of the mounting groove 220 can be used to initially limit the position of the support block 23. A first through hole 2221 is provided on the first side wall 222, a second through hole 2231 is provided on the second side wall 223, and a third through hole 231 is provided on the support block 23. The first through hole 2221, the second through hole 2231, and the third through hole 231 are arranged in a one-to-one correspondence, that is, these three through holes must be aligned on the same straight line. The fastener 24 is inserted into the first through hole 2221, the second through hole 2231, and the third through hole 231 to prevent them from moving in the horizontal and vertical directions.

[0050] Specifically, the fasteners 24 can be screws, pins, or other types of connectors, with screw connections being more common. During installation, the screws are sequentially inserted through the first through-hole 2221, the third through-hole 231, and the second through-hole 2231. Finally, nuts are installed at the ends of the screws and tightened to securely connect the mounting base 22 to the support block 23. To remove the support block 23, simply loosen the nuts and remove the screws, easily removing the support block 23 from the mounting slot 220. This allows for quick assembly and disassembly of the support block 23.

[0051] like Figure 4 and Figure 5 As shown, a positioning structure 25 is further provided between the mounting seat 22 and the support block 23. The positioning structure 25 is used to define the relative position of the support block 23 and the mounting seat 22. In this embodiment, the positioning structure 25 is provided between the mounting seat 22 and the support block 23 to further ensure the stability of the relative position between the support block 23 and the mounting seat 22, thereby preventing relative displacement between the support block 23 and the mounting seat 22 due to vibration or external force during operation, thereby affecting the stability and support effect of the single hydraulic support 21.

[0052] Specifically, the positioning structure 25 can be implemented in a variety of ways. For example, a positioning boss can be provided on the mounting base 22, and a positioning slot can be provided at a corresponding position on the bottom of the support block 23, so that the positioning boss matches the positioning slot, thereby limiting the relative movement between the support block 23 and the mounting base 22. Alternatively, a positioning pin can be provided on the bottom of the support block 23, and a matching positioning hole can be provided on the top of the mounting base 22. The positioning pin can be inserted into the positioning hole to achieve the same positioning effect.

[0053] Furthermore, the positioning structure 25 includes a positioning protrusion 251 and a positioning groove 252. The positioning protrusion 251 is provided on the bottom plate 221, and the extending direction of the positioning protrusion 251 is the same as the extending direction of the fastener 24. The positioning groove 252 is provided at the bottom of the support block 23, and the positioning groove 252 is provided corresponding to the positioning protrusion 251, and the positioning protrusion 251 is located in the positioning groove 252. In this embodiment, the positioning structure 25 includes a positioning protrusion 251 and a positioning groove 252. The positioning protrusion 251 is provided on the bottom plate 221 of the mounting seat 22 and is integrally connected to the mounting seat 22 to enhance the stabilization effect. The positioning groove 252 is provided at the bottom of the support block 23 and is integrally connected to the support block 23. The position of the positioning groove 252 corresponds to the position of the positioning protrusion 251, so that the positioning protrusion 251 can be accurately embedded in the positioning groove 252, so that the mounting seat 22 and the support block 23 are integrally engaged, which not only limits the horizontal movement of the support block 23 on the bottom plate 221 of the mounting block, but also provides a certain vertical stability, ensuring that the connection between the support block 23 and the pillar 21 is more stable.

[0054] Specifically, the positioning protrusion 251 can be circular, square, triangular, or other shapes, as long as it matches the shape of the positioning groove 252. The depth and width of the positioning groove 252 should match the size of the positioning protrusion 251 to ensure that the positioning protrusion 251 can be stably embedded in the positioning groove 252 and will not easily fall out.

[0055] Specifically, the positioning protrusion 251 can be integrally formed with the mounting block, or fixed to the mounting block by welding, bolting, etc. The positioning groove 252 can also be integrally formed with the support block 23, or formed by drilling, cutting, etc. during the processing of the support block 23.

[0056] Furthermore, the connecting assembly 30 includes a plurality of connecting sleeves 31 and connecting rods 32. The extending direction of the connecting sleeves 31 is the same as the extending direction of the pillars 21. The plurality of connecting sleeves 31 are respectively mounted on two adjacent pillars 21. The connecting rods 32 are used to connect the plurality of connecting sleeves 31 on two adjacent pillars 21. In this embodiment, the connecting assembly 30 includes a plurality of connecting sleeves 31 and connecting rods 32. The extending direction of the connecting sleeves 31 is the same as the extending direction of the pillars 21, that is, they are mounted on the pillars 21 in a vertical direction, forming a stable sleeve connection with the pillars 21. The inner diameter of the connecting sleeves 31 is slightly larger than the outer diameter of the pillars 21 to ensure that the connecting sleeves 31 can be smoothly mounted on the pillars 21 without being too loose, thereby maintaining a good fixing effect. The two ends of the connecting rods 32 are respectively connected to the connecting sleeves 31 on the two adjacent pillars 21, serving to strengthen the support of the adjacent pillars 21.

[0057] Specifically, each support 21 can be provided with at least two connecting sleeves 31, and the positions of the connecting sleeves 31 can be pre-marked on the support 21 to ensure accuracy and consistency during installation. The connecting rod 32 can be a straight rod or a rod with a certain angle to accommodate the angle variation between different supports 21.

[0058] Specifically, the connecting rod 32 and the connecting sleeve 31 should be made of a material with high strength and wear resistance, such as high-strength alloy steel, to ensure the durability and reliability of the connecting assembly 30 .

[0059] Furthermore, the connection assembly 30 also includes a locking bolt 33. Each connecting sleeve 31 is provided with a locking bolt 33, which is threadedly connected to the connecting sleeve 31 and is used to fix the relative position of the pillar 21 and the connecting sleeve 31. In this embodiment, each connecting sleeve 31 is provided with at least one locking bolt 33. The locking bolt 33 and the connecting sleeve 31 are threadedly connected, that is, the threaded rod portion of the locking bolt 33 cooperates with the pre-set threaded hole on the connecting sleeve 31 to achieve the installation and removal of the locking bolt 33, thereby ensuring the relative position of the pillar 21 and the connecting sleeve 31 is stable, and preventing the pillar 21 from moving relative to each other during the movement of the self-propelled device or the support process, which may affect the support effect and safety.

[0060] Specifically, after the locking bolt 33 passes through the threaded hole in the connecting sleeve 31, its end is in close contact with the outer wall of the pillar 21. By tightening the locking bolt 33, the position between the pillar 21 and the connecting sleeve 31 is locked. Even if the working surface is subject to large vibrations or external forces, the pillar 21 can remain stable and will not move relative to the connecting sleeve 31. Among them, a gasket is provided on the end of the locking bolt 33 that is in close contact with the pillar 21 to increase the contact area, reduce the pressure of the locking bolt 33 on the outer wall of the pillar 21, avoid damage to the outer wall of the pillar 21 caused by long-term locking, and increase the service life of the pillar 21.

[0061] like Figure 6 As shown, there are four connecting sleeves 31 and two connecting rods 32. The two connecting rods 32 are arranged in a vertically intersecting manner, and each connecting rod 32 is provided with a connecting sleeve 31 at its end. In this embodiment, two connecting rods 32 are used, and the two connecting rods 32 are arranged in a vertically intersecting manner to form an X-shaped structure. This structure can effectively disperse and absorb forces from different directions, improving overall stability. Each connecting rod 32 is provided with a connecting sleeve 31 at both ends. The four connecting sleeves 31 ensure a stable connection between the connecting rods 32 and the support pillars 21, while also facilitating rapid installation and removal on site.

[0062] Specifically, the connection between the connecting rod 32 and the connecting sleeve 31 can be a plug-in connection, that is, the end of the connecting rod 32 can be designed as a plug with a specific shape, and the connecting sleeve 31 has a corresponding socket inside. When the connecting rod 32 is inserted into the connecting sleeve 31, the plug and the socket fit tightly together, achieving a connection. Alternatively, the connecting sleeve 31 can be provided with threads inside, and the end of the connecting rod 32 can also be provided with corresponding threads, so that the connecting rod 32 and the connecting sleeve 31 are further fixed by the threaded connection.

[0063] Furthermore, the inner wall of the first side wall 222 is a first inclined surface 2220, which is inclined in a direction away from the second side wall 223; and / or the inner wall of the second side wall 223 is a second inclined surface 2230, which is inclined more in a direction away from the first side wall 222. In this embodiment, the inner wall of the first side wall 222 is a first inclined surface 2220, which is inclined in a direction away from the second side wall 223. This inclined design helps guide the support block 23 to slide more smoothly into the installation slot 220 during installation, reducing wear on the support block 23. It also facilitates rapid positioning of the support block 23, improving installation efficiency. Similarly, the inner wall of the second side wall 223 is a second inclined surface 2230, which is inclined in a direction away from the first side wall 222. The second inclined surface 2230 has the same design purpose as the first inclined surface 2220. The provision of the second inclined surface 2230 also facilitates the smooth sliding and rapid positioning of the support block 23. Moreover, the design of the second inclined surface 2230 complements the first inclined surface 2220, further enhancing the stability of the support block 23 within the mounting groove 220. Thus, by providing the inclined surfaces on the first side wall 222 and the second side wall 223, the installation and removal process of the support block 23 is optimized, while the stability of the support assembly 20 is enhanced.

[0064] Specifically, the inclination angles of the first inclined surface 2220 and the second inclined surface 2230 can be adjusted as needed, typically ranging from 5° to 30°, to ensure that the support block 23 can slide in smoothly and maintain good stability after being installed. In actual applications, the inclination angles of the first inclined surface 2220 and the second inclined surface 2230 can be the same, or they can be optimized for adaptability based on different on-site environments.

[0065] Furthermore, connecting lugs 110 are provided at both ends of the support plate 11. In this embodiment, connecting lugs 110 are provided at each end of the support plate 11. The support plate 11 serves as a bridge connecting the mobile bracket 10 and the pillar 21. The connecting lugs 110 at both ends are used to achieve a quick and stable connection between the support plate 11 and the mobile bracket 10 and / or adjacent support plates 11, while also facilitating on-site assembly and disassembly and maintenance.

[0066] Specifically, the thickness and width of the connecting lugs 110 should ensure sufficient strength and stability to withstand the forces generated by the single hydraulic strut 21 during operation and prevent damage to the connection. The connecting lugs 110 are provided with at least one connection hole to facilitate connection to the mobile bracket 10 and / or other support plates 11. The connecting lugs 110 should be positioned symmetrically to ensure balance when connected to the support plates 11 and avoid uneven forces caused by asymmetric positioning of the connecting lugs 110, which could affect the stability and safety of the entire device.
