Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: Please refer to Figure 1-6 One embodiment of this utility model provides: a rapid support device for underground mining, installed in an underground roadway, including a support column 1, a connecting frame 3 installed on the support column 1, a connecting device 5 installed on the connecting frame 3, and a crossbeam 4 installed on the connecting device 5.

[0027] Support pillars 1 are symmetrically installed on the left and right sides of the roadway. Support pillars 1 are the main supporting structure of the entire support system, responsible for bearing and distributing pressure from above. The symmetrical installation of support pillars 1 enhances the stability of the overall structure. An arc-shaped frame 6 is connected to the top of each support pillar 1. Through holes are opened on each support pillar 1, and connecting frames 3 are installed within these holes. The connecting frames 3 are inserted into the through holes of support pillar 1 via positioning rods 301, connecting the connecting frames 3 and support pillar 1 into a single unit. Simultaneously, connecting devices 5 are connected to support pillar 1, providing a connection position for the crossbeam 4. Connecting devices 5 are connected to the connecting frames 3, and the two connecting... A crossbeam 4 is installed between the connecting frames 3, with both ends abutting against the connecting frames 3 and aligned with the top of the support column 1. The crossbeam 4 connects the support columns 1 on both sides, providing lateral support, helping to distribute pressure, and enhancing the rigidity of the overall structure. It also assists in supporting the arc-shaped frame 6 at the top, providing additional support and increasing the overall strength of the structure. An arc-shaped block 401 is installed between the crossbeam 4 and the connecting device 5. The arc-shaped block 401 works in conjunction with the connecting device 5 to increase the contact surface with the crossbeam 4, thereby improving the stability and load-bearing capacity of the support.

[0028] The connecting device 5 includes a housing 501, a first clamping plate 502, a second clamping plate 503, and a return spring 504. The housing 501 is connected to the connecting frame 3. The first clamping plate 502 is hinged to the second clamping plate 503, and the second clamping plate 503 is hinged to the housing 501. Both the first clamping plate 502 and the second clamping plate 503 are arc-shaped, forming a cavity between them. This cavity corresponds to the arc-shaped block 401. The first clamping plate 502 and the second clamping plate 503 form a clamping structure through hinge, which can firmly clamp the arc-shaped block 401 on the crossbeam 4, allowing the crossbeam 4 to... 4 is connected between the two support columns 1, and the crossbeam 4 abuts against the connecting frames 3 at both ends to ensure its stability. A horizontally arranged reset plate is connected to the outer circumference of the crossbeam 4. A reset spring 504 is connected to the bottom end of the reset plate. One end of the reset spring 504 is connected to the reset plate, and the other end is connected to the outer shell 501. The reset spring 504 provides elastic support, ensuring that the first clamping plate 502 and the second clamping plate 503 can return to their original shape after being subjected to force. The crossbeam 4 is fixed by the movement of the first clamping plate 502 and the second clamping plate 503, allowing it to be easily disassembled when needed while maintaining the tightness of the connection.

[0029] The connecting frame 3 includes a positioning rod 301, a fixing plate 302, and an L-shaped limiting plate 303. The positioning rod 301 is inserted into a through hole, and its other end is connected to the top of the fixing plate 302. The positioning rod 301 ensures the fixed position of the connecting frame 3 on the support column 1 and prevents displacement. The fixing plate 302 is set on the corresponding end faces of the two support columns 1 and is fixed to the corresponding end faces of the support columns 1, providing additional support and stability for the connecting frame 3. The bottom end of the fixing plate 302 is connected to the L-shaped limiting plate 303, which fits against the support column 1. The L-shaped limiting plate 303 is used to prevent the connecting frame 3 from shifting, increase stability, and ensure the stability of the entire support device. During installation, the positioning rod 301 is first inserted, and then the weight of the L-shaped limiting plate 303 itself drives the fixing plate 302 to rotate, simultaneously driving the L-shaped limiting plate 303 to rotate, so that the L-shaped limiting plate 303 fits against the support column 1.

[0030] A spring 7 is connected to the outer circumference of the arc-shaped frame 6. The arc-shaped frame 6 is connected to the support column 1, serving as an upper support structure to withstand pressure from the top of the tunnel. The spring 7 and the arc-shaped support plate 8 reduce the impact of vibration on the support. The top of the spring 7 is connected to the arc-shaped support plate 8. The spring 7 absorbs vibration from the top of the tunnel, while the arc-shaped support plate 8 contacts the top of the tunnel, providing stable support and reducing deformation caused by vibration. The arc-shaped support plate 8 also abuts against the top of the tunnel to reduce the deformation of the arc-shaped frame 6 caused by vibration.

[0031] A connecting plate is provided between the arc-shaped frame 6 and the support column 1 to connect the arc-shaped frame 6 and the support column 1, ensuring the stability of the arc-shaped frame 6 and facilitating quick disassembly and assembly. Connecting holes are provided on both sides of the connecting plate, and a limiting hole corresponding to the connecting hole is provided at the top of the support column 1. A limiting bolt is inserted into the connecting hole, ensuring that the arc-shaped frame 6 does not shift during use and allowing for quick disassembly. The bottom end of the limiting bolt is positioned within the limiting hole to prevent the arc-shaped frame 6 from shifting, while also facilitating quick connection and disassembly.

[0032] Several reinforcing ribs are evenly distributed within the arc-shaped frame 6 to prevent deformation. The even distribution of these ribs enhances the frame's resistance to deformation, thereby improving the overall strength and stability of the structure.

[0033] During installation, the support column 1 is first placed in the tunnel. Then, the positioning rod 301 of the connecting frame 3 is inserted into the through hole of the support column 1. Subsequently, the L-shaped limiting plate 303, under its own weight, drives the fixing plate 302 to rotate, and the L-shaped limiting plate 303 also rotates and fits against the support column 1. Next, the connecting device 5 is connected to the support column 1. Then, the arc-shaped block 401 is fitted into the cavity between the first clamping plate 502 and the second clamping plate 503 of the connecting device 5. Under the action of the return spring 504, the arc-shaped block 401 is clamped. Next, the crossbeam 4 is connected between the two supports 1, ensuring that both ends of the crossbeam 4 are in contact with the corresponding end faces of the fixing plate 302 of the connecting frame 3, while ensuring that the top of the crossbeam 4 is on the same axis as the support 1 to support the arc frame 6. Then, the stabilizing frame on the crossbeam 4 is connected to the fixing plate 302 to enhance stability. Finally, the arc frame 6 is connected to the top of the support 1 by the limiting bolt, ensuring that the arc support plate 8 is in contact with the top of the roadway. Each component can be transported and installed modularly, reducing the complexity of underground operations and improving construction efficiency.

[0034] Example 2: Please refer to Figure 1-2 Based on Example 1, it also has the following structure:

[0035] It also includes a grounding frame 2, which includes a mounting plate 201, a connecting rod 202, and a grounding plate 203. The mounting plate 201 is symmetrically arranged on the front and rear ends of the support column 1. The mounting plate 201 has several positioning holes, and the support column 1 has threaded holes corresponding to the positioning holes. A screw is inserted into the positioning hole and screwed into the threaded hole. The positioning holes allow the mounting plate 201 to be fixed to the support column 1 by the screw, providing a reliable mechanical connection. The combination of the threaded hole and the screw ensures that the mounting plate 201 will not loosen. The connecting rod 202 is hinged to the mounting plate 201. The main function of 02 is to connect the mounting plate 201 and the grounding plate 203, and to provide a movable connection point. It is connected to the mounting plate 201 by means of hinge, allowing a certain angle of movement, so that the grounding plate 203 of the grounding frame 2 can be adjusted when necessary, ensuring the adjustability and stability of the grounding frame 2. The other end of the connecting rod 202 is screwed into the grounding plate 203. The top four corners of the grounding plate 203 are provided with grounding holes, and grounding plugs are inserted into the grounding holes and connected to the ground. Through the combination of the grounding holes and grounding plugs, the grounding plate 203 can be firmly connected to the ground, ensuring the stability and long-term reliability of the grounding effect.

[0036] Example 3: Please refer to Figure 2-3 Based on Example 1, it also has the following structure:

[0037] The crossbeam 4 also includes a stabilizer frame, which provides additional support and stability to prevent deformation or swaying of the crossbeam 4 during use. The stabilizer frame includes a second connecting rod and a connecting plate. One end of the second connecting rod is hinged to the crossbeam 4, and the other end is hinged to the connecting plate. The connecting plate is connected to the connecting frame 3, and the connecting plate connects the second connecting rod and the connecting frame 3 to ensure the fixation and stability between the two. At the same time, the linkage hole opened on the connecting plate is used to connect with the fixing plate 302 of the connecting frame 3. The connecting plate has a linkage hole, and the connecting frame 3 has a screw hole corresponding to the linkage hole. A positioning bolt is inserted into the linkage hole and screwed into the screw hole. By inserting the positioning bolt into the linkage hole and screwing it into the screw hole, the positioning bolt ensures accurate positioning and stable connection between the connecting plate and the fixing plate 302 of the connecting frame 3, preventing loosening during use and facilitating installation and disassembly.
