Description

Technical Field

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

[0002] Mining engineering refers to the process of extracting mineral resources from the earth through various methods and technologies, including mine design, application of mining technologies, resource processing, and environmental protection. Temporary roadway support devices are facilities used in mining engineering to support and protect the structure of underground roadways, ensuring that the roadways do not collapse or deform during mining, thereby guaranteeing worker safety and the normal operation of equipment. The connection between these two aspects is that temporary roadway support devices are an indispensable part of mining engineering, directly affecting the safety and efficiency of the entire mining operation.

[0003] The working principle of temporary roadway support devices in mining engineering mainly relies on the analysis of the mechanical properties of the surrounding rock mass. The support devices bear and disperse the pressure inside and outside the roadway, preventing rock collapse and deformation. These support devices typically include components such as support frames, anchoring systems, and support plates, effectively maintaining the stability of the roadway. During construction, the support devices form a stable support system through close contact with the surrounding rock strata, thereby ensuring the safety of the roadway, protecting workers, and effectively extending the service life of the roadway. In conclusion, the proper design and application of temporary roadway support devices are crucial for ensuring the safe and efficient operation of mining projects.

[0004] In existing technologies, some temporary support devices for mining roadways are limited by their design and structure, resulting in a small support area. This makes it impossible to effectively expand the support area to adapt to the constantly changing pressure and stress experienced by the roadway during subsequent use. This limitation affects the stability of the support system, increases the risk of roadway collapse, and consequently impacts the safety and efficiency of mining operations. Therefore, to solve this problem, a more flexible structure needs to be considered in the design of the support device, allowing for adjustments and expansion as needed in practical applications to ensure long-term support effectiveness and safety. To this end, a temporary support device for mining roadways is proposed to address the aforementioned issues. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a temporary support device for roadways in mining engineering, which aims to improve the problem that some temporary support devices for roadways in mining engineering cannot expand the support area during subsequent use due to the limited support area.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a temporary support device for roadways in mining engineering, comprising two bases, a main vertical beam fixedly connected to the top of each of the two bases, a telescopic beam slidably connected inside each of the four main vertical beams, a core support plate fixedly connected to the top of each telescopic beam, an expansion mechanism slidably connected to the left and right ends of each core support plate, a limit mechanism threadedly connected inside each base, casters fixedly connected to the bottom sides of each of the two bases, and multiple splicing plates fixedly connected to the adjacent side of each of the two bases;

[0007] The extended support mechanism includes two extended connecting plates, which are externally slidably connected to the left and right sides of the core support plate. An extended support block is externally slidably connected to the opposite side of the two extended connecting plates, and an extended support component is fixedly connected to the bottom of the extended support block.

[0008] As a further description of the above technical solution: the limiting mechanism includes four lead screws, the four lead screws are respectively threaded to the left and right ends of the base, a circular handle is fixedly connected to the top of the four lead screws, and a support base is fixedly connected to the bottom of the four lead screws, the bottom of the support base is in contact with the ground;

[0009] As a further description of the above technical solution: the extended support assembly includes four fixed connecting blocks, the tops of the four fixed connecting blocks are respectively fixedly connected to the bottom of the front and rear ends of the extended support block, an extended vertical beam is rotatably connected inside the four fixed connecting blocks, an extended telescopic block is slidably connected inside the four extended vertical beams, a connecting base plate is fixedly connected to the bottom of the four extended telescopic blocks, a plurality of anti-slip teeth are fixedly connected to the bottom of the four connecting base plates, and a locking block is fixedly connected to the side of the telescopic beam near the extended telescopic block;

[0010] As a further description of the above technical solution: the core support plate has expansion slots inside its left and right sides, the two expansion connecting plates are externally slidably connected in the expansion slots, the two expansion support blocks have connection slots inside their adjacent sides, and the other ends of the two expansion connecting plates are slidably connected in the connection slots.

[0011] As a further description of the above technical solution: the interior of the extended vertical beam is provided with a sliding groove, the exterior of the extended telescopic block is slidably connected in the sliding groove, and the top of the extended telescopic block is provided with a limiting block, which is slidably connected in the sliding groove;

[0012] As a further description of the above technical solution: the interior of the extended vertical beam has two threaded holes, and the interior of the extended telescopic block has four threaded holes, with the threaded holes inside the extended vertical beam corresponding to the threaded holes inside the extended telescopic block;

[0014] As a further description of the above technical solution: the lead screw has a thread on its outside, the circular handle is a combination of two circular ring blocks, and one end of the small opening of the circular handle is connected to the top of the lead screw.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, during installation, the extension vertical beam can be pulled, which in turn moves the fixed connecting block, causing the extension support block to slide. Then, with the extension connecting plate as a connection, the support range of the core support plate is expanded. Simultaneously, during the pulling process, the extension vertical beam breaks free from the limitation of the limiting block, causing it to rotate. Afterward, the extension telescopic block inside the extension vertical beam is pulled, and the connecting base plate and anti-slip teeth at the bottom of the telescopic block contact the ground. This allows the telescopic block and the extension vertical beam to support the extension support block, thus ensuring the stability of the extension support block during the support process.

[0017] 2. In this utility model, when the device needs to be moved, the limiting screws of the extension vertical beam and the extension telescopic block can be loosened, so that the extension telescopic block retracts into the interior of the extension vertical beam. Then, the extension vertical beam pushes the extension support block and the extension connecting plate to reset. Then, the extension vertical beam is rotated, so that the extension vertical beam retracts into the limiting support of the limiting block. Then, the circular handle is rotated. With the help of the thread on the outside of the screw connected to the circular handle, the circular handle rises during rotation, so that the support seat at the bottom of the screw no longer contacts the ground. Then, with the help of the universal wheels at the bottom of the base, the device can move quickly, thereby improving the real-time speed and location change speed of the device.

[0024] 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.

[0025] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a temporary support device for mining tunnels, comprising two bases 1, which are the foundation of the support device and are used to bear heavy loads and ensure the stability of the device in complex terrain. Main vertical beams 6 are fixedly connected to the top of both bases 1, and the main vertical beams 6 are responsible for bearing pressure from above and sides. Telescopic beams 7 are slidably connected inside the four sections of the main vertical beams 6, and the design of the telescopic beams 7 allows for high adaptability within the tunnel. A core support plate 8 connected to its top is the main support surface, which can effectively distribute pressure and maintain structural stability within the tunnel. The core support plate 8 is fixedly connected to the top of the telescopic beams 7, and plays a crucial load-bearing role. Sliding extension mechanisms at its left and right ends allow the support range to be effectively expanded laterally, thus adapting to different tunnel widths. Extension mechanisms are slidably connected to both ends of the core support plate 8. A limit mechanism is threaded inside the base 1. Universal wheels 5 are fixedly connected to the bottom sides of both bases 1, and multiple splicing plates 17 are fixedly connected to the adjacent side of the two bases 1.

[0026] The extended support mechanism includes two extended connecting plates 9, which slide along the extended groove of the core support plate 8 and can be quickly adjusted according to changes in the roadway. The two extended connecting plates 9 are externally slidably connected to the left and right sides of the core support plate 8. An extended support block 10 is externally slidably connected to the opposite side of the two extended connecting plates 9. The extended support block 10 enhances the overall support force and is connected to an extended support assembly at the bottom to ensure the reliability of the support. An extended support assembly is fixedly connected to the bottom of the extended support block 10.

[0027] The extended support assembly includes four fixed connecting blocks 11. The tops of the fixed connecting blocks 11 are fixedly connected to the extended support block 10, allowing the extended vertical beam 12 to rotate and be rearranged as needed. The tops of the four fixed connecting blocks 11 are respectively fixedly connected to the bottom of the front and rear ends on opposite sides of the extended support block 10. The extended vertical beam 12 is rotatably connected inside the four fixed connecting blocks 11. The sliding groove design inside the extended vertical beam 12, combined with the extended telescopic block 13, enables higher support capacity and flexibility. The extended telescopic block 13 is slidably connected inside each of the four extended vertical beams 12. The bottom of the telescopic block 13 is connected to the connecting base plate 14 and is provided with multiple anti-slip teeth 15, which can enhance the stability on the ground, prevent the equipment from sliding when under force, and ensure the safety of the support system. The bottom of each of the four telescopic blocks 13 is fixedly connected to the connecting base plate 14, and the bottom of the four connecting base plates 14 is fixedly connected with multiple anti-slip teeth 15. The telescopic beam 7 is fixedly connected to the side of the telescopic block 13 with a locking block 16. The telescopic beam 7 has five threaded holes inside, and the main vertical beam 6 has four threaded holes inside. The threaded holes inside the telescopic beam 7 correspond to the four threaded holes inside the main vertical beam 6.

[0028] Reference Figures 1 to 3 The limiting mechanism includes four lead screws 2, which are threaded to the left and right ends of the base 1. A circular handle 4 is fixedly connected to the top of each lead screw 2, and a support base 3 is fixedly connected to the bottom of each lead screw 2. The lead screws 2 help control the overall height and ensure accuracy during each support operation. The support base 3 is a crucial component in contact with the ground, ensuring stability of the entire support device during use. The bottom of the support base 3 contacts the ground. The lead screws 2 have threads on their outer surfaces. The circular handle 4 is a combination of two circular ring blocks, with one small end of the handle 4 connected to the top of the lead screw 2.

[0029] The core support plate 8 has expansion slots on its left and right sides, and the two expansion connecting plates 9 are slidably connected to the expansion slots. The two expansion support blocks 10 have connecting slots on their adjacent sides, and the other ends of the two expansion connecting plates 9 are slidably connected to the connecting slots.

[0030] The extension vertical beam 12 has a sliding groove inside, and the extension telescopic block 13 is slidably connected to the outside of the sliding groove. The top of the extension telescopic block 13 is provided with a limiting block, which is slidably connected to the sliding groove. The extension vertical beam 12 has two threaded holes inside, and the extension telescopic block 13 has four threaded holes inside. The threaded holes inside the extension vertical beam 12 correspond to the threaded holes inside the extension telescopic block 13.

[0031] Working principle: The two casters 5 located at the bottom of the two bases 1 enable the device to move quickly, while preventing the device from shaking or even falling apart during the movement.

[0032] When the device reaches the designated position, the circular handle 4 can be rotated to drive the lead screw 2 fixedly connected to the bottom of the circular handle 4. The lead screw 2 rotates and slides with the help of the external thread of the lead screw 2, so that the support seat 3 at the bottom of the lead screw 2 contacts the ground. This avoids accidental sliding due to the presence of the caster wheel 5 and improves the stability of the device.

[0033] The two main vertical beams 6 at the top of the two bases 1 and the telescopic beams 7 inside the main vertical beams 6 serve as the main beams of the device, responsible for providing necessary support for the device. The core support plate 8 located at the top of the telescopic beams 7 serves as the top plate of the device. When it is necessary to expand the support range of the core support plate 8, the expansion vertical beam 12 can be pulled. The expansion vertical beam 12 drives the expansion support block 10 to slide through the fixed connecting block 11. During the sliding process, the expansion support block 10 drives the expansion connecting plate 9, which is slidably connected inside the expansion support block 10, to slide, thereby allowing the expansion connecting plate 9 to slide inside the core support plate 8, ultimately expanding the core support range. The support range of the support plate 8 is then extended. Since the extension vertical beam 12 is rotatably connected to the inside of the fixed connecting block 11, the extension vertical beam 12 can rotate to form a right angle with the ground. Then, the extension telescopic block 13 inside the extension vertical beam 12 is pulled, so that the connecting base plate 14 at the bottom of the extension telescopic block 13 contacts the ground. Then, the screw holes inside the extension vertical beam 12 and the extension telescopic block 13 are threadedly connected to the fixing screws, thereby fixing the position of the extension vertical beam 12 and the extension telescopic block 13. Then, the anti-slip teeth 15 at the bottom of the connecting base plate 14 form an enhanced friction layer during contact with the ground, thereby preventing the device from sliding unexpectedly.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
