DETAILED DESCRIPTION
[0033] The following are specific embodiments of the present invention, and the technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these embodiments.
[0034] like Figure 1-12 As shown, the present invention provides a column-type rapid support device for a mine tunnel, comprising a base 1, a roof support part that can be raised and lowered and located on the upper side of the base 1, and two first hydraulic pillars 11 that are located between the base 1 and the roof support part and support the roof support part. A construction channel for a tunneling machine is provided between the base 1, and a buffer part is installed on the upper end of the roof support part, and the buffer part is in contact with the tunnel roof. When in use, the device supports the roof support plate 2 through the first hydraulic pillar 11, and the supporting force of the tunnel roof comes from the roof support part. The roof support plate 2 supports upward, and the supporting force acts on the tunnel roof through the buffer part to support the tunnel roof. After being compressed, the buffer part can move downward a small distance to buffer the supporting force of the roof support plate 2, thereby avoiding the roof support plate 2 directly impacting the tunnel roof and causing damage to the tunnel roof, and avoiding the phenomenon of the support being crushed due to excessive mining height; the lower end of the base 1 is slidably connected with a moving arm 14 that can move to the left side, The front and rear ends of the moving arm 14 are respectively hinged with a push jack 15, and the other end of the push jack 15 is hinged with the base 1. The push jack 15 is used to push the moving arm 14 to move forward, and then pull the base 1 to move forward after the moving arm 14 moves forward, so as to facilitate the frame moving. When the frame is moved, the buffer part can always press against the top of the tunnel, and float according to the different heights of the top of the tunnel, so that the buffer part always applies pressure to the top of the tunnel, which can effectively avoid repeated impacts on the tunnel roof during the frame moving, resulting in the situation that the tunnel roof falls off, and when the buffer part moves up and down during the movement, the friction force on the tunnel roof and the frame moving resistance during the frame moving can be reduced, which is convenient for frame moving and reduces the wear of the tunnel; because the telescopic end of the push jack 15 is connected with the moving arm 14, when in use, the push jack 15 is controlled to extend to push the moving arm 14 to move forward, and then when the push jack 15 is reset, the base 1 can be pulled to move to the left side, so as to achieve the effect of frame moving;
[0035] Furthermore, in order to ensure that the pressure on the tunnel is maintained continuously and stably when the frame is moved to avoid impacting the tunnel roof, the roof support portion includes a roof support plate 2 and a first push plate 18 slidably connected to the left and right sides of the roof support plate 2, and a reinforcement beam 20 is fixedly connected between the left and right first push plates 18;
[0036] The buffer part includes a buffer plate 3 and a second push plate 19 installed on the left and right sides of the buffer plate 3, and the first push plate 18 and the second push plate 19 corresponding to each other are slidably connected to each other; a plurality of first hydraulic buffers 17 are fixedly connected between the buffer plate 3 and the top plate support plate 2, and the left and right sides of the front and rear ends of the upper end of the first push plate 18 are respectively hinged with the second hydraulic buffer 23, and the other ends of the second hydraulic buffer 23 are respectively hinged with the second push plate 19, and the supporting force of the top plate support plate 2 acts on the top plate of the tunnel through the first hydraulic buffer 17 and the second hydraulic buffer 23, and the first hydraulic buffer 17 and the second hydraulic buffer 23 rely on hydraulic damping to resist the impact generated by the top plate support plate 2 during initial support The impact force is buffered, and when the frame is moved, the pressure difference caused by the different heights of the tunnel top can be compensated by the corresponding contraction of the first hydraulic buffer 17 and the second hydraulic buffer 23, so that pressure is always generated on the tunnel top, and the tunnel top is effectively supported and protected; and in order to further improve the stability of the top plate support part, a composite connecting rod structure is connected between the top beam support part and the base 1, and the composite connecting rod structure is synchronously stretched when the top plate support part is raised or lowered, so that the stability of the top plate support part during support is enhanced by the composite connecting rod structure, and when the buffer part is subjected to the pressure of the tunnel roof, it can not only be buffered by the first hydraulic buffer 17, but the composite connecting rod structure can also disperse the load to improve the support effect.
[0037] like Figure 4As shown, the composite connecting rod structure includes a side plate 4 fixedly connected to the front and rear sides of the lower end of the top plate, and the lower surface of the side plate 4 is respectively hinged with a first parallel rod 9 and a second parallel rod 10 arranged in parallel with each other. The lower ends of the first parallel rod 9 and the second parallel rod 10 on the same side are jointly hinged with a triangular plate 7. The first parallel rod 9, the second parallel rod 10, the top plate support plate 2 and the triangular plate 7 form a parallelogram structure. Under the support and limitation of the first parallel rod 9 and the second parallel rod 10, the top plate support plate 2 is in a state of being parallel to the tunnel top plate; the front and rear sides of the upper end of the base 1 are respectively hinged with a first support rod 5 and a second support rod 6 arranged in parallel with each other. The side surface away from the base 1 is hinged to the corresponding triangular plate 7 respectively. The first support rod 5, the second support rod 6, the base 1 and the triangular plate 7 also form a parallelogram structure. The end of the second support rod 6 away from the base 1 is hinged to a transition rod 8 respectively. The other ends of the two corresponding transition rods 8 are fixedly connected to a support rod, and the support rods are respectively rotatably connected to the surface of the first parallel rod 9; the bottom of the first hydraulic support 11 is hinged to the base 1, and the telescopic ends of the first hydraulic support 11 are respectively hinged to the support rods. The first hydraulic support 11 acts as the main supporting force. When the first hydraulic support extends upward, it can push the first parallel rod 9 and the second parallel rod 10 on the upper side through the connection with the support rod. The first parallel rod 9 and the second parallel rod 10 swing upward in a circle, and at the same time, the first parallel rod 9 and the second parallel rod 10 drive the first support rod 5 and the second support rod 6 on the lower side to swing upward in a circle through the transmission of the transition rod 8. Moreover, since the first parallel rod 9 and the second parallel rod 10 swing upward in a circle, they also drive the top plate support plate 2 to move to the right while moving upward. Therefore, the first support rod 5 and the second support rod 6 can drive the first parallel rod 9, the second parallel rod 10 and the top plate support plate 2 to move to the left synchronously through the triangular plate 7 when the first support rod 5 and the second support rod 6 swing upward in a circle, thereby compensating for the displacement of the top plate support plate 2 caused by the swinging of the first parallel rod 9 and the second parallel rod 10. distance, so that the top plate support plate 2 is in a vertical lifting state under the support of the first hydraulic pillar 11, and vertical pressure support is performed to ensure the supporting effect; further, in order to improve the safety of the top plate support plate 2 during support, the front and rear sides of the base 1 are respectively hinged with second hydraulic pillars 36, and the second hydraulic pillars 36 are respectively located on the left side of the first hydraulic pillar 11. When the first hydraulic pillar 11 is extended or retracted, the second hydraulic pillar 36 will also be extended or retracted synchronously, without affecting the swinging state of the first parallel rod 9 and the second parallel rod 10 driven by the first hydraulic pillar 11. When the first hydraulic pillar 11 fails, the second hydraulic pillar 36 can support the top plate support plate 2 to play a safety effect.
[0038] like Figure 4 and Figure 5As shown, in order to increase the protection area of the tunnel roof when the frame is moved and to improve the stability of the tunnel roof when the frame is moved, the front and rear sides of the upper end of the moving arm 14 are respectively hinged with the second connecting rod 13, and the front and rear sides of the lower end of the first push plate 18 on the left are respectively hinged with the first connecting rod 12, and the corresponding ends of the first connecting rod 12 and the second connecting rod 13 are hinged to each other. Under the linkage action of the first connecting rod 12 and the second connecting rod 13, when the moving arm 14 moves, it can synchronously drive the first push plate 18 on the left to move, and under the linkage of the reinforcement plate, the right side The push plate can move with the first push plate 18 on the left side, so that the first push plate 18 first moves to the left side to increase the supporting area, and then drives the top plate support plate 2 and the buffer plate 3 to move when the base 1 moves, so as to achieve the effect of gradually moving the frame; a reinforced hydraulic support 16 is hinged between the first and second linkage rods 12 and 13 corresponding to the upper and lower parts; the reinforced hydraulic support can fix the first linkage rod 12 and the second linkage rod 13, improve the linkage effect of the first linkage rod 12 and the second linkage rod 13, and when moving the frame, such as Fig.12 As shown, the push jack 15 is in a state where the telescopic end is tilted upward. When the push jack 15 pushes the moving arm 14 to move, the pressure fixing rod fixes the first connecting rod 12 and the second connecting rod 13, and the pressure mainly acts on the base 1, so that the friction between the base 1 and the ground is increased, which is convenient for driving the first push plate 18 and the second push plate 19 to move under the transmission of the first connecting rod 12 and the second connecting rod 13. When the push jack 15 drives the base 1 to move, the reinforced hydraulic support 16 pressurizes the first connecting rod 12 and the second connecting rod 13, increases the pressure of the moving arm 14 on the ground, and thus improves the moving arm 14. The friction between the arm 14 and the ground can then drive the base 1 to move forward when the push jack 15 pulls the base 1; and when transferring the device, in order to prevent the movable arm 14 from separating from the base 1 and affecting the transfer efficiency, the front and rear sides of the lower end of the movable arm 14 are respectively fixedly connected with support rails 30, and the front and rear sides of the left end of the base 1 are respectively opened to the right side with guide rail grooves 31 corresponding to the support rails 30. The support rails 30 are slidably connected to the guide rail grooves 31, which not only facilitates the movement between the movable arm 14 and the base 1, but also allows the movable arm 14 and the base 1 to remain in a connected state, thereby facilitating transfer.
[0039] A protective beam 33 is hinged at the right end of the two second parallel rods 10 for bearing the pressure of collapsed roof rock and preventing falling waste rock from the goaf from entering the construction channel between the bases 1 and affecting the construction. The front and rear sides of the right end of the first sliding plate 18 on the right are hinged with hinged rods 32 respectively, and the other ends of the hinged rods 32 are hinged to the protective beams 33 respectively. When the first sliding plate 18 moves during the frame shifting process, the protective beam 33 can also swing synchronously under the linkage of the hinged rod 32 to maintain the protective effect. Furthermore, the front and rear ends of the protective beam 33 are respectively fixedly connected with guard plates 34 for protecting the sides of the protective beam 33 and preventing falling waste rock from entering the construction channel through the sides.
[0040] The left and right sides of the front and rear ends of the first push plate 18 and the second push plate 19 are respectively provided with a limit sleeve 21 and a limit plate 22 that are slidably connected to each other, and the upper ends of the limit plates 22 are respectively fixedly connected to the second push plates 19, and under the action of the sliding connection between the limit sleeve 21 and the limit plate 22, the second push plate 19 is stably slidably connected to the first push plate 18, thereby improving the stability of the second push plate 19; the front and rear ends of the first push plate 18 are respectively provided with connecting grooves along the length direction, and the lower ends of the limit sleeves 21 are respectively fixedly connected with connecting sliders, and the connecting sliders are respectively slidably connected to the connecting grooves. Under the sliding connection between the connecting sliders and the connecting grooves, it is convenient to maintain the connection effect with the second push plate 19 when the first push plate 18 moves outward, thereby maintaining the vertical limiting effect of the limit sleeve 21 and the limit plate 22.
[0041] The left and right ends of the support plate 2 and the buffer plate 3 are respectively provided with rectangular grooves inwardly, a first cross bar 26 is formed between every two rectangular grooves on the surface of the support plate 2, and a second cross bar 27 is formed between every two rectangular grooves on the surface of the buffer plate 3. The surface of the first push plate 18 is evenly provided with a plurality of first matching grooves 29 with openings at both ends from front to back, and the first matching grooves 29 are respectively arranged corresponding to the first cross bars 26. Under the staggered engagement of the first matching grooves 29 and the first cross bars 26, the first push plate 18 can be installed on the top plate support The inner side of the plate 2 is overlapped with the top plate support plate 2, and the surface of the second push plate 19 is evenly provided with a plurality of second matching grooves 28 with openings at both ends from front to back, and the second matching grooves 28 are respectively arranged corresponding to the second cross rods 27. Under the staggered engagement of the second matching grooves 28 and the second cross rods 27, the second push plate can also be installed on the inner side of the buffer plate 3 and overlapped with the buffer plate 3, so as to facilitate the movement of the top plate support plate 2 and the buffer plate 3 when the frame is moved while maintaining sufficient support for the tunnel top plate, and maintain the support range when the frame is moved.
[0042] Furthermore, in order to improve the stability of the moving frame and prevent the presence of debris on the moving road from affecting the stability of the moving frame, the left end of the moving arm 14 is fixedly connected to a cleaning plate 35 whose bottom is flush with the bottom of the support guide rail 30, and the upper side of the left end of the cleaning plate 35 is provided with an inclined surface inclined to the right. When the moving arm 14 moves, the cleaning plate 35 can remove debris on the moving road, maintain the stability of the moving frame, and ensure the safety of the device when in use.
[0043] When in use, the device is placed on the upper side of the tunnel boring machine, and the top plate support plate 2 is supported by the first hydraulic support 11. The supporting force of the tunnel roof comes from the top plate support part, and the top plate support plate 2 is supported upward. The supporting force acts on the tunnel roof through the buffer part to support the tunnel roof. The buffer part can move downward a small distance after being compressed to buffer the supporting force of the top plate support plate 2, thereby avoiding the top plate support plate 2 from directly impacting the tunnel roof and causing damage to the tunnel roof, and can also avoid the phenomenon of crushing the support due to excessive mining height. During the operation of the tunnel boring machine, the device can be pushed by controlling the push jack 15 to move along with the movement of the tunnel boring machine. The frame is moved dynamically. During the moving process, the first push plate 18 will first move to the left to increase the support area, and then the top plate support plate 2 and the buffer plate 3 will be driven to move when the base 1 moves, so as to achieve the effect of gradually moving the frame and ensure the stability of the tunnel roof when the frame is moved; and when the frame is moved, the buffer part can always be pressed against the top of the tunnel and float according to the height of the top of the tunnel to effectively support the tunnel roof. During the moving process, the cleaning plate 35 can remove debris on the moving path to maintain the stability of the moving frame. The protective beam 33 can bear the pressure of the collapsed top plate rock to prevent the gangue from falling from the goaf from entering the construction channel between the bases 1 and affecting the construction.
