Description

Technical Field

[0001] This utility model relates to the field of support device technology, and in particular to a rapid support device for mining roadways. Background Technology

[0002] Rapid roadway support equipment is a device used in underground roadways such as coal mines to quickly support and reinforce the surrounding rock after excavation. It enables the roadway support to play an active role in adjusting and controlling the deformation of the surrounding rock. The support should be installed before the surrounding rock becomes loose or damaged, so that the support can work together with the surrounding rock to bear the load while the surrounding rock still has its own bearing capacity, rather than waiting until the surrounding rock has become loose, damaged, and almost completely lost its self-bearing capacity before using the support to bear the weight of the fallen rock blocks.

[0003] A search revealed that the document with publication number "CN219034735U" mentions "a roadway support device, belonging to the field of mining technology, including a roof, with a first side plate and a second side plate symmetrically installed at the bottom of the roof, multiple first anchor cables installed on the roof, multiple mutually symmetrical second and third anchor cables installed on the first and second side plates respectively, and two U-shaped support rods symmetrically installed between the first and second side plates, with multiple evenly distributed fourth anchor cables installed on the support rods." In use, the support rods and multiple fourth anchor cables allow the support rods to be pressed against the roadway floor, and then the fourth anchor cables are used to fix the support rods and the roadway floor, thus strengthening the roadway floor and reducing the problem of bulging of the roadway floor.

[0004] However, traditional support equipment cannot adjust its height according to the height of the tunnel, which limits the device. It is also not suitable for tunnels with different curvatures, the installation method is more complicated, and the material cost is higher.

[0005] Therefore, we provide a rapid support device for mining roadways to solve the above problems. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Please see Figure 1-6 As shown, this utility model provides a technical solution: a rapid support device for mining roadways, including a main column 1, a groove on the upper surface of the main column 1, an adjustment component 2 at the top of the main column 1, the adjustment component 2 including a support rod 201 with a slot connected to the inside of the groove at the top of the main column 1, a support component 3 at the bottom of the main column 1, a total of four sets of main columns 1, and a protective component 4 between the main columns 1, the protective component 4 including a support plate 401 installed between the main columns 1.

[0033] Furthermore, the support rods 201 overlap to form a triangular structure. A threaded slot is provided at the upper front end of each support rod 201. A hydraulic rod 202 is installed at the rear of each support rod 201. Threaded posts 203 are welded to both ends of the hydraulic rod 202. The support rods 201 and hydraulic rods 202 are connected by the threaded posts 203. Nuts 204 are provided on the outer side of each support rod 201, allowing the angle of the two support rods 201 to be freely adjusted to adapt to different roadways, improving the flexibility and applicability of the device. After adjusting to the appropriate angle according to the roadway, the two support rods 201 are connected by the threaded posts 203 and fixed by the nuts 204. The lower end of each support rod 201 is engaged in a groove at the top of the main column 1 to prevent the device from swaying left and right and to avoid tilting due to pressure. The two tilted support rods 201 overlap to form a triangular structure, thereby improving the stability of the device. No complex tools are required; assembly can be completed quickly using the threaded posts 203, improving construction convenience and efficiency.

[0034] Furthermore, the support rod 201 is provided in four sets. A connecting steel block 205 is welded to the upper end of the support rod 201, and a connecting column 206 is welded to the middle of the connecting steel block 205. The connecting column 206 is an adjustable hydraulic cylinder. By adjusting the length of the connecting column 206, the connecting column 206 can adapt to roadways of different lengths, improving the flexibility and applicability of the device. It eliminates the need to stock multiple lengths of rods, enabling rapid length adjustment, reducing material usage costs, and improving construction efficiency.

[0035] Furthermore, the support component 3 includes a steel plate 301 installed at the bottom of the main column 1. A lifting head 302 is welded to the bottom of the steel plate 301. A jack 303 is installed below the lifting head 302. The jack 303 tightly presses the steel plate 301 welded above the lifting head 302 against the bottom of the main column 1. The height of the main column 1 can be adjusted by finely adjusting the height of the lifting head 302, so that the device can adapt to tunnels of different heights, improve the flexibility of the device, simplify installation, increase installation speed, and improve construction efficiency.

[0036] Furthermore, there are four sets of steel plates 301, and a steel column 304 is set between every two sets of steel plates 301. Steel forks 305 are welded to the front and rear ends of the steel column 304. A square hole 306 is opened in the middle of the steel fork 305, and the lifting head 302 passes through the middle of the square hole 306. The user can freely install the steel fork 305 according to actual needs. When adjusting the height of one end of the lifting head 302, the two sets of steel plates 301 are kept at the same horizontal line by the steel fork 305 to prevent the main column 1 from tilting during the adjustment of the height of the lifting head 302, which would pose a safety hazard.

[0037] Furthermore, protrusions are welded to the upper left and upper right ends of the support plate 401, and threaded holes 402 are opened in the middle of the protrusions. A screw 403 is threadedly connected to the middle of the threaded hole 402, and a nut 404 is threadedly connected to the front end of the screw 403. An angle brace 405 is welded to the bottom end of the support plate 401. The angle brace 405 provides stability for the device. The user can freely combine the support plates 401 to fit the curvature of the tunnel according to the curvature of the tunnel, so that each support plate 401 is evenly stressed. Different tunnels can be used flexibly. The screw 403 enables rapid installation and improves construction efficiency. In addition, the disassembled support plates 401 can be reused to improve cost performance.

[0038] Furthermore, a protective net 406 is installed at the top of the support plate 401. The front and rear ends of the protective net 406 are welded with ring buckles 407. The ring buckles 407 are connected to the screw rod 403 by a slot. The ring buckles 407 can be quickly locked onto the screw rod 403, which facilitates quick installation and disassembly, improves work efficiency and ease of operation, and the protective net 406 effectively prevents gravel from falling and improves the safety of the device.

[0039] Working principle: Move the device to the working position, then adjust multiple support plates 401 to a suitable angle according to the curvature of the tunnel. Screws 403 are then screwed into the threaded holes 402 on the support plates 401, connecting them in pairs. Nuts 404 are then used to secure them. Angle braces 405 below the support plates 401 provide stability to the entire device. A protective net 406 is installed on the support plates 401, and ring buckles 407 are secured to the screws 403. The support rods 201 are then adjusted and connected with threaded posts 203, secured with nuts 204. Finally, the support rods 201 are placed in the groove at the top of the main column 1, and the connecting posts 206 are welded. On the connecting steel block 205 above the support rod 201, adjust the length of the hydraulic rod 202 and the connecting column 206 according to the length of the roadway. Use the jack 303 to lift the steel plate 301 and adjust the height of the main column 1, thereby ensuring that the hydraulic rod 202 connected to the support rod 201 is tightly attached to the support plate 401. When it is necessary to adjust the height of the main column 1 at the same time, the square hole 306 above the steel fork 305 is locked on the lifting head 302, and the steel fork 305 is connected together through the steel column 304, thereby realizing the synchronous adjustment of the height of the main column 1. When not needed, it can be removed, thus completing the use process of a mining roadway rapid support equipment.
