Description

Technical Field

[0001] This utility model relates to the field of roadway support technology, and in particular to a support device for adjusting the deformation of the roof of a coal mine roadway. Background Technology

[0002] Roof deformation is a common and serious problem in coal mining. Due to ground stress, changes in rock structure, and the effects of mining activities, the roof is prone to subsidence, cracking, and even collapse, threatening miners' lives and production efficiency. Therefore, roof support is necessary for coal mine roadways.

[0003] A composite component for coal mine roadway support, disclosed in CN221346973U, includes: an arched frame; two support pipes arranged longitudinally on opposite sides of the roadway, with longitudinal slots on opposite sides of the two support pipes; a lifting component including a carrier plate and a lifting assembly, the carrier plate being slidably connected within the support pipes, and the lifting assembly being located at the bottom of the carrier plate; the lifting assembly being used to drive the carrier plate up and down; and a buffer assembly located on the carrier plate, with both ends of the arched frame passing through the slots of the two support pipes and positioned on the buffer assembly. This composite component for roadway support can transfer roadway deformation during ground pressure manifestations, effectively protecting the support structure and personnel working below. Furthermore, the lifting assembly makes installation convenient and quick. However, due to the limited protective effect of the buffer assembly and protective steel plate on the support structure, the support structure may deform and collapse under high pressure.

[0004] Therefore, a coal mine roadway roof deformation adjustment support device has now been developed that can enhance overall stability and improve protective performance when subjected to high pressure. Utility Model Content

[0005] To overcome the shortcomings of existing coal mine roadway support composite components, buffer components, and protective steel plates, which have limited protective effects on the support structure and may deform and collapse under high pressure, this utility model provides a coal mine roadway roof deformation adjustment support device that can enhance overall stability and improve protective performance under high pressure.

[0006] The technical solution of this utility model is: a coal mine roadway roof deformation adjustment support device, including a support frame, a sliding frame, elastic elements, damping rods, shock absorbers, buffer plates, extension components, and support components. The support frame has two parts, left and right, and the upper sides of the support frame are connected by a sliding frame through damping. Two elastic elements are connected to the sliding frame and the support frame, and damping rods are rotatably connected to the sliding frame on both the front and rear sides of the support frame. Multiple shock absorbers are connected to the sliding frame, and buffer plates are connected to the upper sides of the shock absorbers. An extension component that can increase the floor space is provided between the sliding frame and the support frame. The sliding frame is provided with a support component that can support the damping rods.

[0007] Furthermore, multiple fixing nails are provided on the lower sides of both the front and rear parts of the support frame.

[0008] Furthermore, the elastic element is a telescopic spring.

[0009] Furthermore, the buffer plate is curved.

[0010] Furthermore, the extension assembly includes a slider, a connecting rod, and an extension plate. Sliders are connected to the lower sides of both the front and rear parts of the sliding frame. The sliders are slidably connected to the adjacent support frame. Connecting rods are rotatably connected to the left and right sides of the sliders. Extension plates are rotatably connected to the lower sides of the connecting rods. The extension plates are slidably connected to the adjacent support frame.

[0011] Furthermore, the support assembly includes a first rack, a gear, a second rack, a movable frame, and a support block. The left and right sides of the movable frame are each connected to a first rack. The lower part of the support frame is rotatably connected to a gear on the side that is close to each other. The upper part of the support frame is slidably connected to a movable frame. The movable frame is connected to a second rack. The first rack and the second rack mesh with the adjacent gear. The upper sides of the front and rear parts of the movable frame are rotatably connected to a support block through damping.

[0012] The beneficial effects are as follows: When the sliding frame moves downward, it drives the slider to move downward, causing the connecting rod to push the extension plate to move outward and contact the ground, increasing the contact area between the support frame and the ground. At the same time, the first rack moves downward, causing the gear to rotate and mesh with the second rack, thereby causing the moving frame to move upward, so that the support block contacts the damping rod and supports the damping rod. This achieves the effect of enhancing overall stability and improving protective performance when subjected to high pressure. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0019] A coal mine roadway roof deformation adjustment support device, such as Figures 1-4 As shown, the system includes a support frame 1, a sliding frame 2, elastic elements, damping rods 4, shock absorbers 5, buffer plates 6, an extension assembly, and a support assembly. The support frame 1 has two parts, left and right. Each of the front and rear lower parts of the support frame 1 is provided with four fixing nails for easy installation and fixing. The upper part of the support frame 1 is connected to the sliding frame 2 via a damping sliding mechanism. The sliding frame 2 and the support frame 1 are each connected by two elastic elements, which are extension springs 3. The front and rear parts of the support frame 1 are rotatably connected to the sliding frame 2 via damping rods 4. Six shock absorbers 5 are connected to the sliding frame 2. The upper part of the shock absorbers 5 is connected to the buffer plates 6. The buffer plates 6 are arc-shaped to facilitate support of the tunnel roof. An extension assembly is provided between the sliding frame 2 and the support frame 1. The sliding frame 2 is provided with a support assembly.

[0020] like Figure 1 and Figure 3 As shown, the extension assembly includes a slider 7, a connecting rod 8, and an extension plate 9. The slider 7 is connected to the lower sides of both the front and rear parts of the sliding frame 2. The slider 7 is slidably connected to the adjacent support frame 1. The connecting rod 8 is rotatably connected to the left and right sides of the slider 7. The extension plate 9 is rotatably connected to the lower side of the connecting rod 8. The extension plate 9 is slidably connected to the adjacent support frame 1.

[0021] like Figure 1 and Figure 4 As shown, the support assembly includes a first rack 10, a gear 11, a second rack 12, a movable frame 13, and a support block 14. The left and right sides of the sliding frame 2 are connected to the first rack 10. The lower side of the support frame 1 is rotatably connected to the gear 11. The upper part of the support frame 1 is slidably connected to the movable frame 13. The movable frame 13 is connected to the second rack 12. The first rack 10 and the second rack 12 are both meshed with the adjacent gear 11. The upper sides of the front and rear parts of the movable frame 13 are rotatably connected to the support block 14 through damping.

[0022] When using this utility model, the support frame 1 is first fixed on both sides of the coal mine roadway, so that the buffer plate 6 on the sliding frame 2 contacts the roof of the roadway to support the coal mine roadway. When the roof of the coal mine roadway deforms, the buffer plate 6 bears increased pressure and moves downward. The shock absorber 5 buffers and dampens the buffer plate 6. When the sliding frame 2 moves downward, the sliding frame 2 is buffered by the force of the telescopic spring 3. The damping rod 4 is used to disperse the pressure borne by the sliding frame 2.

[0023] As the sliding frame 2 moves downward, it drives the slider 7 to move downward, causing the connecting rod 8 to push the extension plate 9 outward to contact the ground, increasing the contact area between the support frame 1 and the ground, thereby enhancing the stability of the support frame 1.

[0024] As the sliding frame 2 moves downward, it drives the first rack 10 to move downward, causing the first rack 10 to mesh with the gear 11. The gear 11 rotates and meshes with the second rack 12, which in turn causes the second rack 12 and the moving frame 13 to move upward, so that the support block 14 contacts the damping rod 4, supporting the damping rod 4 and strengthening its structural strength and stability. This enhances the overall stability and improves the protective performance when subjected to high pressure.

[0025] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
