Description

Technical Field

[0001] This invention relates to the field of coal mining technology, and in particular to a mobile support device for coal mine roadways. Background Technology

[0002] Coal, as a crucial component of my country's primary energy source, is strategically vital for ensuring national energy security through its safe and efficient mining. Coal mine roadways are the lifeline of coal mining, and their stability directly impacts the normal progress of the working face and the safety of miners. With the rapid development of fully mechanized mining technology, the advance speed of the working face has significantly increased, placing unprecedentedly high standards and stringent requirements on the support technology of roadways, especially the mobile support equipment in the advance support sections of the roadways.

[0003] Currently, in coal mine longwall roadways, especially in the advance support section ahead of the working face, the commonly used equipment is still single hydraulic props combined with metal articulated roof beams, or some early, simple mobile support platforms. These traditional devices have gradually revealed many insurmountable technical bottlenecks and safety hazards in practical applications, making them unsuitable for the demands of modern, high-yield, and high-efficiency working faces.

[0004] The primary challenge lies in the conflict between equipment mobility and stability. The floor conditions of mining roadways are extremely complex, often exhibiting unevenness, pits, rock piles, and floor heaves after mining activities. Existing equipment lacks an effective overall chassis stabilization system and obstacle response mechanism during movement, making it prone to bumps, tilting, and even jamming. This unstable movement is not only inefficient but also causes continuous impact and vibration on the equipment's structure, especially hydraulic lines, valves, and connections, creating potential for leaks and damage. When the roadway roof experiences pressure or severe mining stress, the equipment may withstand instantaneous excessive impact. Traditional structures lack effective energy absorption and buffering designs, easily leading to overload failure of critical load-bearing components, directly threatening operational safety.

[0005] Secondly, existing equipment has significant shortcomings in support adjustment performance. The roadway roof is not an ideal flat surface; its uneven shape requires support equipment to have a high degree of self-adaptability. However, many devices either lack adjustment functions or their height and angle adjustments are independent and cannot be linked. Operators need to rely on experience for multiple tedious adjustments, making it difficult to achieve large-area surface contact between multiple support mechanisms and the roof, ultimately leading to extremely uneven distribution of support resistance. Some support points may reach their limits rapidly due to concentrated pressure, causing damage to cylinders or deformation of structural components; while other support points may fail to fully contact the roof, resulting in inadequate support. This abnormal stress phenomenon can cause minor damage to the equipment itself, requiring frequent maintenance, or, in severe cases, insufficient overall support strength can lead to localized roof collapse or even overall instability, resulting in catastrophic accidents. In addition, the cumbersome and inefficient adjustment process also seriously consumes valuable production time. The equipment is often bulky in the support state, encroaching on the already limited roadway space, hindering the smooth passage of large equipment such as coal mining machines and transportation equipment, causing mining operations to be interrupted and restricting the further improvement of working face efficiency.

[0006] Finally, the core support structures of existing support equipment tend to be conservative in their material and mechanical design, urgently requiring innovation. Traditional support beams or protective plates often adopt a purely rigid design concept, sacrificing material toughness while pursuing high strength. When facing continuous large deformation pressure from the roof, such rigid structures lack the necessary capacity for pressure yielding and deformation coordination. Like hardwood, they are easily broken; once the pressure exceeds their yield limit, irreversible plastic deformation or sudden fracture can easily occur, resulting in the loss of support function. They cannot utilize the elastic deformation of the structure itself to absorb and dissipate energy, nor can they cleverly transform the locally borne pressure into the supporting internal force of the overall structure, thereby achieving a redistribution of force and shared load-bearing—that is, they lack the intelligent mechanical characteristics of "deformation-assisted force." This fundamentally limits the full realization of the equipment's support potential and its survivability under extreme conditions.

[0007] The present invention aims to solve the technical problems existing in the prior art. To this end, a mobile support device for coal mine roadways is proposed. Summary of the Invention

Detailed Implementation

[0038] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0039] The following disclosure provides numerous different embodiments or examples for implementing various structures of the invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples. Such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed.

[0040] Example 1, please refer to Figures 1 to 7 In this embodiment of the invention, a mobile support device for a coal mine roadway includes: two sets of synchronous obstacle-clearing and fitting moving mechanisms arranged in parallel and facing each other; one set of the synchronous obstacle-clearing and fitting moving mechanisms includes a mobile mounting plate 1, an adaptive fitting moving module is provided on the lower side of the mobile mounting plate 1, and rotation limit obstacle-clearing modules are symmetrically arranged at both ends of the mobile mounting plate 1.

[0041] Each of the movable mounting plates 1 is equipped with an angle adjustment lifting support mechanism. The angle adjustment lifting support mechanism includes an angle synchronous adjustment module provided on the upper side of the movable mounting plate 1 and two sets of lifting support modules provided on it. The two sets of lifting support modules on the two movable mounting plates 1 are arranged facing each other.

[0042] An adaptive support mechanism is connected to the lifting support module facing each other. The adaptive support mechanism is positioned across the top of the two movable mounting plates 1. The adaptive support mechanism includes an arc-shaped support plate 3, and force-bearing support modules are provided at both ends of the arc-shaped support plate 3.

[0043] The equipment is moved into the coal mine's longwall roadway by an external traction device. Then, with the extension and retraction adjustment of the lifting support module and the angle adjustment of the angle synchronization module, the angle and height of the arc support plate 3 are changed, thereby achieving close support for the top of the coal mine's longwall roadway. On this basis, the leverage support module is adjusted to change the difficulty of the arc support plate 3 under stress deformation, thereby adjusting the support stability of the mobile support equipment. Then, the mobile support equipment in the coal mine's longwall roadway is moved stably by the movement of the adaptive fitting mobile module. At the same time, the rotation limit and obstacle clearing module on it can clear debris on the movement path, ensuring the continuous and stable movement of the equipment and improving its anti-interference ability.

[0044] Example 2, based on Example 1, please refer to... Figure 1 , Figure 2 , Figure 4 , Figure 6 , Figure 7 In this embodiment of the invention, the adaptive fitting and moving module includes a plurality of adaptive swing mounting frames 33 evenly spaced below the movable mounting plate 1. A movable roller 34 is rotatably mounted at the middle position of the adaptive swing mounting frame 33. The two ends of the movable roller 34 are rotatably connected to the adaptive swing mounting frame 33 through a drive shaft 27. Adjacent adaptive swing mounting frames 33 are connected by a support shaft 36. A limiting mounting post 40 is provided at the middle position of the support shaft 36. Elastic limiting plates 39 are symmetrically arranged on both sides of the limiting mounting post 40. A positioning mounting groove 24 is provided on the lower side of the movable mounting plate 1. A directional mounting post 37 is provided at the upper end of the limiting mounting post 40. A directional mounting sleeve 25 is provided in the positioning mounting groove 24 in cooperation with the directional mounting post 37. A limiting spring post 38 is symmetrically arranged at the upper end of the limiting mounting post 40 in cooperation with the directional mounting post 37. The upper end of the limiting spring post 38 is connected to the positioning mounting groove 24.

[0045] The movable mounting plate 1 is moved by driving the movable roller 34 to rotate by driving the rotating shaft 27. The ground of the coal mine roadway to be built and under construction is uneven. Therefore, when passing through these ground surfaces, the adaptive swing mounting frames 33 on both sides of the supporting rotating shaft 36 can rotate, so that the movable roller 34 can contact the ground, providing stable support and movement.

[0046] When there are large potholes and protrusions, the adaptive swing mounting frame 33 and the elastic limiting plate 39 make rigid contact, restricting further rotation of the adaptive swing mounting frame 33 and preventing the support shaft 36 from contacting the ground. At this time, the adaptive swing mounting frame 33, the support shaft 36, the limiting mounting column 40, and the elastic limiting plate 39 form an integral structure. The directional movement of this integral structure is achieved through the cooperation of the directional mounting column 37 and the directional mounting sleeve 25. At the same time, with the deformation of the limiting spring column 38, the movable mounting plate 1 can cross potholes and protrusions, ensuring the passability of the equipment, and improving the stability during passage.

[0047] Example 3, based on Example 1, please refer to... Figure 4 , Figure 5 , Figure 12 In this embodiment of the invention, the rotation limit clearing module includes a limit mounting frame 26 symmetrically arranged at both ends of a movable mounting plate 1. A rotation clearing block 5 is provided at the end of the limit mounting frame 26 via a limit rotating shaft 13. A rotation limit block 28 is provided on the outer side of the limit rotating shaft 13. A stationary limit block 29 is provided on the limit mounting frame 26 to restrict the rotation of the rotation limit block 28. A plurality of clearing teeth 30 are provided at the end of the rotation clearing block 5. A crushing mounting groove 32 is recessed on the lower side of the rotation clearing block 5. A crushing roller 31 is rotatably arranged in the crushing mounting groove 32.

[0048] As the mobile mounting plate 1 moves, the clearing teeth 30 at the end of the rotating clearing block 5 at one end come into contact with the ground on its path. When it encounters an obstacle, it can remove the obstacle and crush the ground after the obstacle is removed by the crushing roller 31, so as to achieve a smooth and unobstructed moving path.

[0049] When an excessive impact is encountered, the rotating clearing block 5, together with the limiting shaft 13 and the rotating limiting block 28 on it, rotates until the rotating limiting block 28 and the stationary limiting block 29 come into contact, limiting the further rotation of the rotating clearing block 5, providing limiting support for the movable mounting plate 1, and protecting the directional mounting column 37, the directional mounting sleeve 25, and the limiting spring column 38 from being damaged by excessive impact.

[0050] Example 4, based on Example 1, please refer to... Figure 1 , Figure 2 , Figure 4 , Figure 8 , Figure 9In this embodiment of the invention, the angle synchronization adjustment module includes two angle adjustment mounting plates 23 symmetrically arranged on the upper side of the movable mounting plate 1. Two synchronous rotating columns 17 are symmetrically arranged between the two angle adjustment mounting plates 23 via a rotating shaft. A synchronous gear 19 is provided at the middle position of each synchronous rotating column 17. The synchronous gears 19 on the symmetrically arranged synchronous rotating columns 17 mesh with each other. A steering gear 18 is symmetrically arranged on the outer side of each synchronous rotating column 17. An adjustment drive component 21 is symmetrically arranged on the upper side of the movable mounting plate 1 in conjunction with the two synchronous rotating columns 17. Each adjustment drive component 21 is symmetrically arranged with a drive gear 35 via a rotating shaft. The drive gear 35 meshes with the steering gear 18. An air pipe 22 is connected to each movable mounting plate 1 on one side of the adjustment drive component 21 for introducing compressed air to drive the adjustment drive component 21.

[0051] By adjusting the drive component 21, the drive gear 35 is rotated. The drive gear 35 meshes with the steering gear 18 to achieve the rotation of a synchronous rotating column 17. Since the two synchronous rotating columns 17 are meshed with the synchronous gear 19, the two synchronous rotating columns 17 rotate synchronously in opposite directions, ensuring that the angle of the lifting support module is always adjusted synchronously, so that the force on the lifting support module is balanced and the safety of the equipment is improved.

[0052] Example 5, based on Example 1, please refer to... Figures 1-3 , Figure 11 In this embodiment of the invention, the lifting support module includes a rotating mounting frame 16 on the synchronous rotating column 17 between the steering gear 18 and the synchronous gear 19. A rotating mounting plate 20 is provided at the end of the rotating mounting frame 16. A supporting telescopic column 2 is provided on the rotating mounting plate 20. A rotating support frame 14 is provided at the end of the supporting telescopic column 2 via a rotating shaft. A fixed mounting frame 15 is provided on the rotating support frame 14 via a rotating shaft. The fixed mounting frame 15 is connected to the lower side of the arc-shaped support plate 3. The two rotating shafts connected to the rotating mounting frame 16 are arranged perpendicularly in space. A wear-resistant hard rubber layer 9 is provided on the upper side of the arc-shaped support plate 3. Several striped rubber protrusions 10 are provided on the outer side of the wear-resistant hard rubber layer 9. Several primary limiting reinforcing plates 7 are symmetrically arranged at the middle position of the lower side of the arc-shaped support plate 3. A limiting support spring 8 is connected between the symmetrical primary limiting reinforcing plates 7. Several secondary limiting reinforcing plates 6 are evenly arranged between the primary limiting reinforcing plates 7 and the two ends of the arc-shaped support plate 3. Adjacent secondary limiting reinforcing plates 6 are arranged opposite each other.

[0053] The leverage support module includes leverage rotating plates 4 symmetrically arranged at both ends of the arc support plate 3. One end of the leverage rotating plate 4 is connected to the arc support plate 3 through a reset rotating shaft 11. Several wear-resistant rubber strips 12 are evenly arranged on one side of the leverage rotating plate 4.

[0054] As the angles of the two synchronous rotating columns 17 are adjusted synchronously, the rotating mounting frame 16 and rotating mounting plate 20 fixed on them, together with the supporting telescopic column 2, achieve synchronous angle adjustment. Then, by adjusting the length of the supporting telescopic column 2, the support position of the arc-shaped support plate 3 is adjusted. Since the two rotating shafts connected on the rotating mounting frame 16 are set vertically, the arc-shaped support plate 3 installed on the fixed mounting frame 15 can adjust the support angle according to the specific structure of the top of the coal mine mining roadway when supporting the top of the coal mine mining roadway, until the wear-resistant hard rubber layer 9 of the arc-shaped support plate 3 contacts the top of the coal mine mining roadway. At this time, the striped rubber protrusions 10 on the wear-resistant hard rubber layer 9 contact the specific structure of the top of the coal mine mining roadway, improving the stability of the support fixation.

[0055] As the supporting force changes, the arc-shaped support plate 3 deforms. When the middle of the arc-shaped support plate 3 is subjected to force, the limiting support spring 8 between the first-level limiting reinforcing plates 7 is stretched, limiting the further deformation of the arc-shaped support plate 3. If the arc-shaped support plate 3 deforms further, with the rotating shaft on the fixed mounting frame 15 as the apex, the end of the arc-shaped support plate 3 warps, which just realizes the pre-adjusted angle of the lever-rotating plate 4 contacting the side wall of the coal mine return roadway, and generating deformation and support, providing support for the arc-shaped support plate 3. As the contact area between the lever-rotating plate 4 and its wear-resistant rubber strip 12 and the side of the coal mine return roadway increases, the static friction force in the vertical direction increases, distributing the supporting force to the side wall of the coal mine return roadway. On the one hand, it can significantly improve the supporting performance of the arc-shaped support plate 3, and on the other hand, it reduces the stress on the equipment and improves the durability of the equipment.

[0056] When the two ends of the arc-shaped support plate 3 are deformed by force, the secondary limiting reinforcing plates 6 come into contact with each other until they come into contact with the primary limiting reinforcing plate 7. The secondary limiting reinforcing plates 6 and the primary limiting reinforcing plates 7 that come into contact along the arc-shaped support plate 3 form a complete supporting reinforcing rib. At this time, the limiting support spring 8 is compressed by force, and together with the secondary limiting reinforcing plates 6 and the primary limiting reinforcing plates 7 that come into contact at both ends, it improves the rigidity and toughness of the arc-shaped support plate 3, thereby improving the support performance of the equipment.
