Description

[0002] During the coal mining process, paste filling technology can be used. By filling the goaf with paste, it forms a high-strength support body after solidification, which can effectively inhibit roof collapse and overburden subsidence, and significantly reduce the risk of surface collapse. In addition, through paste filling, coal gangue can be converted into filling material, realizing the resource utilization of solid waste and reducing the area occupied by gangue mountain from the source.

DETAILED DESCRIPTION

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0036] In order to enable those skilled in the art to better understand the solutions of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0037] Please refer to Figures 1 to 3 , Figure 1 A schematic structural diagram of a specific embodiment of the tunnel blocking device provided by the present invention; Figure 2 for Figure 1 A side view of the tunnel blocking device shown; Figure 3 for Figure 1 A top view of the tunnel blocking device is shown.

[0038] In this embodiment, the tunnel blocking device includes:

[0039] The blocking assembly 1 includes a blocking body 11, an upper telescopic block 12, and left and right telescopic blocks 13. The upper telescopic block 12 and the left and right telescopic blocks 13 are both movably arranged on the blocking body 11. The upper telescopic block 12 can be extended and retracted in the vertical direction relative to the blocking body 11, and the left and right telescopic blocks 13 can be extended and retracted in the left and right directions relative to the blocking body 11. The front sides of the blocking body 11, the upper telescopic block 12, and the left and right telescopic blocks 13 are used to form a blocking surface;

[0040] A driving mechanism is used to pull the blocking assembly 1 to move along the tunnel. The driving mechanism is connected to the blocking assembly 1 via a hinge 4, and the driving mechanism can be extended and retracted in the vertical direction to press against or separate from the top surface of the tunnel. Specifically, the hinge 4 can be part of the blocking assembly 1 or part of the driving mechanism, or the first part of the hinge 4 is fixed to the blocking body 11 of the blocking assembly 1, and the second part of the hinge 4 is fixed to the driving mechanism.

[0041] The angle adjustment drive member 5 is used to adjust the inclination angle of the blocking body 11 in the vertical direction. One end of the angle adjustment drive member 5 is connected to the driving mechanism, and the other end is connected to the blocking body 11, and the hinge 4 and the angle adjustment drive member 5 are connected to the blocking body 11 at different heights along the vertical direction.

[0042] Specifically, when the spacing of the tunnel to be blocked is small, the blocking surface of the blocking component 1 can be adjusted to the minimum size unit, and the angle of the blocking surface of the blocking component 1 can be adjusted by adjusting the angle adjustment drive member 5 connected thereto, thereby blocking the tunnel and preventing the paste from overflowing; the angle adjustment drive member 5 can be a jack, which pushes the blocking component 1 to tilt through telescopic control; the left and right telescopic blocks 13 include a left telescopic block and a right telescopic block, and the left telescopic block and the right telescopic block are respectively located on the left and right sides of the blocking body 11, and the left telescopic block and the right telescopic block are closedly connected to the blocking body 11 by a left push drive component and a right push drive component, and the position adjustment of the left telescopic block and the right telescopic block is achieved by the extension and contraction of the left push drive component and the right push drive component; the upper telescopic block 12 is closedly connected to the blocking body 11 by an upper telescopic drive component, and the upper telescopic block is closed by the upper telescopic drive component. The extension and retraction of the telescopic drive component can realize the position adjustment of the upper telescopic block 12; the left telescopic block and the right telescopic block can be a plate structure, and the left push drive component, the right push drive component and / or the upper telescopic drive component can be a jack; the left push drive component, the right push drive component and the upper telescopic drive component can be connected to the control system, and the left push drive component, the right push drive component and / or the upper telescopic drive component can be automatically controlled by the control system; if the tunnel size is wider and the height is higher, the left push drive component and the right push drive component installed on the inside will extend the left telescopic block and the right telescopic block of the blocking component 1 to increase the width, and the upper telescopic drive component drives the upper telescopic block 12 to increase the height; of course, in order to ensure that the blocking effect of the blocking component 1 is good, the blocking surface should be a flat structure, similar to a wall to block the paste in the tunnel.

[0043] Furthermore, the driving mechanism can extend and retract in the vertical direction to press the top surface of the tunnel or separate from the top surface of the tunnel. When the driving mechanism needs to advance, the driving mechanism shortens in the vertical direction and separates from the top surface of the tunnel. At this time, the driving mechanism can advance; when the blocking assembly 1 needs to move, the driving mechanism extends in the vertical direction, presses the top surface of the tunnel, and pulls the blocking assembly 1 to move.

[0044] Specifically, the angle adjustment drive member 5 can also be a jack structure, and the hinge 4 and the angle adjustment drive member 5 are connected to the blocking body 11 at different heights in the vertical direction, which can ensure that the blocking body 11 will swing when the angle adjustment drive member 5 is extending and retracting; further, for the adjustment of the upper telescopic block 12 and the left and right telescopic blocks 13, the on-site construction personnel can manually adjust the position of the upper telescopic block 12 and / or the left and right telescopic blocks 13 based on the actual conditions in the tunnel through human judgment; of course, a control system can also be set to automatically adjust the upper telescopic block 12 and / or the left and right telescopic blocks 13 through the control system, and the size of the space in the tunnel can be obtained through a visual sensor.

[0045] The tunnel plugging device provided by the present invention, through the setting of the plugging assembly 1, utilizes the plugging body 11, the upper telescopic block 12 and the left and right telescopic block 13 to form a plugging surface, thereby achieving effective plugging of the paste. At the same time, the height of the plugging surface is adjusted by the telescopic movement of the upper telescopic block 12 relative to the plugging body 11 in the vertical direction, and the width of the plugging surface is adjusted by the telescopic movement of the left and right telescopic block 13 relative to the plugging body 11 in the left and right directions. Thus, it can adapt to tunnels of different heights and widths, and improve the scope of application while ensuring a good plugging effect. In addition, By setting up the driving mechanism, the blocking component 1 is driven to move along the tunnel to realize the automatic blocking process; in addition, by setting up the angle adjustment driving member 5, the inclination angle of the blocking body 11 in the vertical direction is changed through the extension and contraction of the angle adjustment driving member 5, thereby changing the inclination angle of the blocking surface in the vertical direction. This can ensure a good blocking effect when the bottom surface of the tunnel is uneven, and when the blocking component 1 moves, by appropriately adjusting the inclination angle of the blocking surface in the vertical direction, it is also beneficial to avoid the problem of the blocking component 1 being unable to move due to excessive adhesion between the blocking surface and the paste.

[0046] In some embodiments, the driving mechanism includes a support assembly 2 and a moving assembly 3, the support assembly 2 is connected between the moving assembly 3 and the blocking assembly 1, the support assembly 2 can be extended and retracted in the vertical direction to press the top surface of the tunnel or separate from the top surface of the tunnel, and the top surface of the support assembly 2 constitutes a guide surface adapted to the top surface of the tunnel; the front side of the support body 21 of the support assembly 2 is connected to the rear side of the blocking body 11 of the blocking assembly 1; specifically, the angle adjustment drive member 5 and the hinge member 4 are both connected between the support assembly 2 and the blocking assembly 1, the support assembly 2 plays a transition role, and the support assembly 2 and the moving assembly 3 can both be extended and retracted in the vertical direction to press the top surface of the tunnel The top surface of the laneway or separated from the top surface of the laneway; when the mobile component 3 needs to be pushed forward, the support component 2 extends in the vertical direction to press the top surface of the laneway, the mobile component 3 shortens in the vertical direction, and the mobile component 3 is separated from the top surface of the laneway. At this time, the mobile component 3 can be pushed forward and the support component 2 remains stationary; when the mobile component 3 is pushed into place, the mobile component 3 extends in the vertical direction to press the top surface of the laneway, the support component 2 shortens in the vertical direction, and the mobile component 3 is separated from the top surface of the laneway. At this time, the support component 2 can drive the blocking component 1 to move, and the mobile component 3 remains stationary. After completing one push, the repeated process can achieve continuous movement of the blocking component 1. A pulling drive 6 can be set between the support component 2 and the mobile component 3, and the pulling effect of the pulling drive 6 on the mobile component 3 and the support component 2 can be achieved by the extension and contraction of the pulling drive 6.

[0047] In some embodiments, the support assembly 2 includes a support body 21, a support column driver 22, a support top beam 23 and a connecting rod mechanism 24, the top surface of the support top beam 23 constitutes a guide surface, the support column driver 22 is arranged on the support body 21, the support top beam 23 is connected to the support column driver 22, and the support column driver 22 is used to drive the support top beam 23 to rise and fall to press the top surface of the tunnel or separate from the top surface of the tunnel; the front side of the support assembly 2 is connected to the blocking assembly 1; the connecting rod mechanism 24 is connected between the support top beam 23 and the support body 21, and the connection point of the connecting rod mechanism 24 and the support top beam 23 is different from the connection point position of the support column driver 22 and the support top beam 23. With this arrangement, the support top beam 2 The front and rear parts of 3 are each supported, and the position of the support top beam 23 is stable; the support column driver 22 can be connected to the control system, and the control system can realize automatic control of the support column driver 22; specifically, the support column driver 22 can be a jack, and the support column driver 22 is used to support and adjust the height of the support top beam 23, and the top surface of the support top beam 23 is a plane; when the support component 2 is fixed, the support top beam 23 can be pressed against the top surface of the tunnel to ensure the stability of the support component 2. When the support component 2 is moving, the support top beam 23 can ensure the smooth movement of the support component 2 under the restriction of the top surface of the tunnel; the setting of the connecting rod mechanism 24 can ensure the stability of the support top beam 23 during the lifting process.

[0048] It should be noted here that the blocking assembly 1 is located in front of the driving mechanism, the driving mechanism is located in the rear of the blocking assembly 1, and the left-right direction is perpendicular to the front-back direction and the front-back direction.

[0049] In some embodiments, the linkage mechanism 24 includes a main rod 241, a first connecting rod 242, and a second connecting rod 243. One end of the main rod 241 is hinged to the support top beam 23, while the first and second connecting rods 242, 243 are both hinged to the other end of the main rod 241. The ends of the first and second connecting rods 242, 243 facing away from the main rod 241 are hinged to the support body 21. Specifically, the main rod 241, the first and second connecting rods 242, 243, and the support column driver 22 form an articulated four-bar stabilization mechanism that maintains the stability of the support assembly 2 and adapts to the height of the roadway roof. Specifically, by employing a four-bar stabilization mechanism, the four-bar stabilization mechanism enables the support top beam 23 to maintain approximately horizontal movement during the raising and lowering process, reducing the change in the angle between the support top beam 23 and the roadway roof, and providing uniform support force on the roadway roof. Furthermore, the mechanism exhibits excellent force transmission performance, capable of transmitting pressure from the roadway roof to the support body 21 via the four-bar stabilization mechanism. A roof plate may be provided at the roadway roof.

[0050] In some embodiments, a guide plate 211 is extended from the side of the support body 21 away from the blocking component 1, and a slide groove 311 is provided on the movable component 3 for the guide plate 211 to be inserted and slide, and the slide groove 311 is used to limit the guide plate 211 in the vertical direction and the left and right directions; specifically, the guide plate 211 extends from the rear of the support body 21 to guide and prevent the movable component 3 at the rear from falling over. The guide plate 211 should have a certain height to effectively prevent the movable component 3 from falling over.

[0051] In some embodiments, a chamfer is provided on the top of the rear side of the guide plate 211 to facilitate the insertion of the guide plate 211 into the slide groove 311 and reduce the collision between the guide plate 211 and the slide groove 311.

[0052] In some embodiments, the moving assembly 3 and the supporting assembly 2 are connected via a pull-drive member 6. There are at least two guide plates 211 and at least two slide slots 311, each located on the left and right sides of the blocking assembly 1 and the moving assembly 3. The extension direction of the pull-drive member 6 is parallel to the extension direction of the guide plates 211, and the pull-drive member 6 is disposed between adjacent guide plates 211. Specifically, the pull-drive member 6 can also be a jack. The pull-drive member 6 can be connected to a control system for automatic control of the pull-drive member 6. The above configuration is designed to accommodate wider lanes. Multiple blocking assemblies 1 are combined, and two adjacent blocking assemblies 1 are connected using a transition blocking member 7, so that the transition blocking member 7 communicates with the blocking surface of the blocking assembly 1 to form a new, wider blocking surface. Each blocking assembly 1 is independently configured with a drive mechanism to facilitate movement of the blocking assembly 1. Adjacent drive mechanisms are connected using a transition connector 8 to prevent them from tipping over. The transition connector 8 can adapt to positional differences between different drive mechanisms through its own telescopic adjustment.

[0053] In some embodiments, the moving assembly 3 includes a moving body 31, a moving column driving member 32 and a moving top beam 33. The moving column driving member 32 is arranged on the moving body 31, and the moving top beam 33 is connected to the moving body 31 in the vertical direction to limit the moving top beam 33 to move only in the vertical direction. The top surface of the moving top beam 33 is also a plane; the moving body 31 and the moving top beam 33 constitute an upper and lower nested telescopic mechanism; the moving top beam 33 is connected to the moving column driving member 32, and the moving column driving member 32 is used to drive the moving top beam 33 to rise and fall to press the top surface of the tunnel or separate from the top surface of the tunnel; specifically, the moving column driving member 32 can also be a jack; the moving column driving member 32 can be connected to the control system to realize automatic control of the moving column driving member 32 through the control system.

[0054] like Figures 4 to 6 As shown, Figure 4 This is a schematic diagram of the connection between multiple groups of blocking components 1 and multiple groups of driving components in the tunnel blocking device provided by the present invention; Figure 5 for Figure 4 A front view of the tunnel blocking device shown; Figure 6 for Figure 4 Top view of the tunnel blocking device shown

[0055] In some embodiments, the number of the blocking components 1 and the number of the driving mechanisms are at least two, and they are connected one-to-one; further comprising:

[0056] The transitional blocking member 7 is connected between adjacent blocking components 1, and the transitional blocking member 7 corresponds to the position of the blocking surface. Specifically, in order to reduce the need for the transitional blocking member 7, when multiple groups of blocking components 1 and driving mechanisms are combined, if it is necessary to adjust the left and right telescopic stoppers 13, the left telescopic stopper or the right telescopic stopper that is not connected to the transitional blocking member 7 should be adjusted. For example, the left telescopic stopper of the blocking component 1 on the left and / or the right telescopic stopper of the blocking component 1 on the right can be adjusted to achieve the size adjustment of the blocking surface in the combined blocking device.

[0057] The transition connector 8 is connected between the connection seats of adjacent driving mechanisms. The transition connector 8 is a telescopic member used to telescope during the movement of different driving mechanisms to adapt to the distance between adjacent connection seats.

[0058] Specifically, since the movement amplitudes and speeds of different driving mechanisms may be different, the transition connector 8 adapts to the distance changes between the connecting seats on adjacent driving mechanisms by telescoping. Of course, preferably, the movement amplitudes and speeds of different driving mechanisms are the same to ensure the synchronous operation of different blocking components 1; of course, the movement amplitudes and speeds of different driving mechanisms may also be slightly different. The maximum telescopic length of the transition connector 8 is not easy to be too large, and the transition connector 8 can play an anti-falling role, that is, the adjacent driving mechanisms are connected together through the transition connector 8, which can prevent the transition connector 8 from tipping over in the left and right directions through mutual constraints. The telescopic length of the transition connector 8 can be set as needed and should not be too large, so as to meet the position deviation of adjacent driving mechanisms.

[0059] In some embodiments, a connecting seat is provided on the support assembly 2 of the driving mechanism, the transition connector 8 is hinged to the connecting seat, and the height of the transition connector 8 is flush with the height of the connecting seat.

[0060] In some embodiments, the transition sealing member 7 is a plate sealing member, and the side edges of the transition sealing member 7 along the left and right directions are hinged to the side edges of the sealing surface along the left and right directions; the plate sealing member can be a steel plate, and the use of the plate sealing member can improve the flatness of the sealing surface and improve the sealing effect, but the flexibility is poor.

[0061] In some embodiments, the transition blocking member 7 is a flexible blocking member, and the side edges of the transition blocking member 7 along the left and right directions are fixedly connected to the side edges of the blocking surface along the left and right directions; a flexible blocking member, such as a flexible protective net plus an isolation cloth, has better flexibility.

[0062] Specifically, in a specific embodiment, the moving component 3 adjusts its height by moving the column drive 32 and is connected to the support component 2 by pulling the drive 6; the moving method of the blocking component 1 is as follows: the moving column drive 32 descends to drive the moving top beam 33 to descend → the middle support component 2 does not move, the pulling drive 6 is extended, and the moving component 3 is pushed forward → the moving column drive 32 is extended to drive the moving top beam 33 to rise and connect to the top → the middle support component 2 is lowered → the pulling drive 6 is retracted, and the middle support component 2 is driven forward to complete the entire pulling cycle; if the tunnel blocking width is too wide, two blocking devices can be used in a group to work, connected by a transition connector 8, and the front end of the blocking component 1 is hung with a transition blocking component 7 to achieve tunnel blocking.

[0063] This tunnel blocking device can adapt well to various tunnel and roof conditions. It can adopt single device form and combined device form according to the tunnel width, reducing labor intensity of personnel and effectively ensuring personnel operation safety. This device is based on practicality and safety, reducing labor intensity, improving blocking quality and ensuring safe production.

[0064] In addition to the above-mentioned tunnel blocking device, the present invention also provides a coal mining equipment including the above-mentioned tunnel blocking device.
