[0001] This invention belongs to the technical field of coal mine support equipment, and particularly relates to a rapid support device for coal mine roadways crossing faults. Background Technology

[0002] During underground coal mining, it is necessary to excavate coal mine roadways. However, due to the presence of geological structures such as faults in the underground coal and rock strata, there is a risk of falling rocks or roadway collapse during the construction process of roadways passing through faults. Therefore, coal mine support devices are usually installed at the point where the roadway passes through a fault to support the roadway and prevent it from collapsing.

[0003] In existing technologies, the large size of coal mine support devices coupled with the narrowness of roadways leads to a lengthy setup time. Furthermore, different tunneling equipment excavates roadways with varying cross-sectional areas, while existing support devices are generally of fixed dimensions, making them unsuitable for roadways with different cross-sectional areas.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Example 1:

[0032] Reference Figures 1-4 As shown, the present invention provides a rapid support device for coal mine roadways crossing faults, comprising:

[0033] Telescopic support rod 1;

[0034] Telescopic component 2 has a mesh structure. Both ends of the telescopic component 2 are slidably connected to the slide rod 3 through two rotating components. By adjusting the relative distance between the two rotating components on the same side, the overall length of the telescopic component 2 changes. Both ends of the slide rod 3 are connected to the telescopic support rod 1.

[0035] Mother plate 4, several mother plates 4 are connected by connecting components and telescopic parts 2 respectively, and the opposite side walls of any two adjacent mother plates 4 are connected to the two sides of the daughter plate 5 by telescopic parts;

[0036] Support plate 6 is mounted on the top surface of mother plate 4 via a support part.

[0037] The telescopic component 2 is connected to two sliding rods 3 at both ends via two rotating assemblies. Adjusting the relative distance between the two rotating assemblies on the same side controls the overall length of the telescopic component 2, thereby adjusting the distance between the two sliding rods 3. When the distance between the two rotating assemblies decreases, the telescopic component 2 extends; when the relative distance increases, the telescopic component 2 shrinks. The smaller size of the telescopic component 2 facilitates handling, and its length can be adjusted according to the tunnel width, improving the applicability of the device to tunnels of different sizes. Since the mother plate 4 is mounted on the telescopic component 2 via connecting assemblies, therefore... When the telescopic component 2 extends, the distance between two adjacent mother plates 4 increases. At the same time, the telescopic part exposes the sub-plate 5 between two adjacent mother plates 4 to the outside, ensuring the airtightness of the support top surface and blocking the falling gravel at the fault point of the roadway, thus preventing injury accidents. Several support plates 6 set on the top surface of the mother plate 4 have an arc-shaped structure. The support part can adjust the angle of the support plate 6, so the support plate 6 can fit in close contact with the roadway top surface, thus ensuring good support. At the same time, the two ends of the sliding rod 3 are connected to the telescopic support rod 1, realizing the overall height extension of the device and ensuring close contact between the support plate 6 and the roadway top surface.

[0038] The scheme is further optimized. The rotating component includes a sleeve 7, which is slidably sleeved on the slide rod 3. A rotating component 8 is fixedly connected to the side wall of the sleeve 7, and the rotating component 8 is rotatably connected to one end of the telescopic component 2.

[0039] like Figure 3As shown, the sleeve 7 and the rotating component 8 enable the connection point on the same side of the telescopic component 2 to move on the slide rod 3. The change in the relative position of the rotating component on the same slide rod 3 drives the change in the length of the telescopic component 2 connected to it, thus achieving adaptation to tunnels of different sizes.

[0040] The scheme is further optimized. The connecting component includes a connecting rod 9. One end of the connecting rod 9 is fixed to the bottom surface of the mother plate 4, and the other end of the connecting rod 9 passes through the hinge of the telescopic member 2 and is fixed to the base plate 10. A limit ring 11 is also sleeved on and fixed to the connecting rod 9. The limit ring 11 is in contact with the top surface of the telescopic member 2.

[0041] The connecting rod 9 can serve as a hinge rod at the hinge of the telescopic member 2 of the mesh structure. At the same time, the limiting ring 11 and the base plate 10 provided on the connecting rod 9 ensure that the longitudinal position of the connecting rod 9 and the telescopic member 2 will not change. This also ensures the supporting performance of the connecting rod 9 on the mother plate 4. Furthermore, when the telescopic member 2 extends or retracts, it can drive the mother plate 4 to extend or retract as well.

[0042] The design is further optimized so that the telescopic part includes a fixing block 12, which is fixed to the side of the sub-plate 5 facing the mother plate 4. A through groove 13 is provided on the side wall of the mother plate 4, and a limiting cavity 14 is connected in the through groove 13. The sub-plate 5 and the through groove 13 are in sliding contact, and the fixing block 12 and the inner wall of the limiting cavity 14 are in sliding contact.

[0043] like Figure 2 As shown, when two adjacent mother plates 4 move in opposite directions under the action of the telescopic member 2, the sub-plate 5 slidably connected to the two mother plates 4 can be covered or released, thereby improving the bearing capacity of the support top surface for falling gravel at the fault in the coal mine roadway and avoiding crushing accidents. The fixed block 12 and the limiting cavity 14 ensure that the sub-plate 5 will not leave the limited range of the mother plate 4.

[0044] The design is further optimized so that the support part includes a support rod 15, one end of which is fixedly connected to the support plate 6, and the other end of the support plate 6 is fixedly connected to the top surface of the mother plate 4. An angle adjustment component is provided on the support plate 6.

[0045] The support rod 15 connects the support plate 6 and the mother plate 4. At the same time, the support plate 6 is set as an arc plate that matches the curvature of the roadway top surface, ensuring its fit to the roadway and realizing the support of the roadway.

[0046] The design is further optimized so that the angle adjustment component includes two rotating blocks 16, which are rotatably connected by a rotating shaft 17. The support rod 15 is adjusted in angle through the angle adjustment component.

[0047] To ensure the support performance of the support rod 15 on the support plate 6, the two rotating blocks 16 are provided with a maximum rotation angle, and the rotation angle of the angle adjustment parts provided on the mother plate 4 at different positions is different. The adjustable angle increases from the center position of the top surface of the support to both sides.

[0048] The scheme is further optimized by adding a telescopic support rod 1. The bottom surface of the telescopic support rod 1 includes a hydraulic telescopic cylinder 18, and the output end of the hydraulic telescopic cylinder 18 is connected to a lifting rod 19.

[0049] The hydraulic telescopic cylinder 18 can drive the lifting rod 19 to rise and fall, ultimately achieving the adjustment of the overall height of the support.

[0050] In a further optimized design, one end of the slide rod 3 is fixedly connected to a first abutment block 20, and a through hole 21 is opened on the top of the side wall of the lifting rod 19. The other end of the slide rod 3 passes through the two through holes 21 of the two lifting rods 19. The end of the slide rod 3 away from the first abutment block 20 is provided with an external thread and is threadedly connected to a second abutment block 22. The first abutment block 20 contacts one lifting rod 19, and the second abutment block 22 contacts the other lifting rod 19.

[0051] The two sliding rods 3 are connected to the four lifting rods 19, which enables the two sliding rods 3 to be raised and lowered, thereby realizing the raising and lowering of the support structure of the top surface.

[0052] The design is further optimized by fixing a plate 23 to the bottom side wall of the hydraulic telescopic cylinder 18, and fixing the plate 23 to the ground by means of pins 24.

[0053] The telescopic support rod 1 can be fixed at a suitable position on the roadway floor by the cooperation of the pin 24 and the fixing plate 23.

[0054] When the device is in use, firstly, all components are transported to the designated location in the roadway. Then, the four telescopic support rods 1 are fixed in the appropriate position with pins 24. The hydraulic telescopic cylinder 18 is controlled to lower the lifting rod 19 to the lowest position. The threaded end of the slide rod 3 is inserted into the through hole 21 of the lifting rod 19. The sleeves 7 on the two rotating components at one end of the telescopic component 2 are fitted onto the slide rod 3. Then, the other slide rod 3 is inserted into the through hole 21 of the lifting rod 19 and the two sleeves 7 at the other end of the telescopic component 2, and the two slide rods 3 are fixed with two second abutment blocks 22. Since the telescopic component 2 drives the mother plate 4 to be positioned in the appropriate position, the lateral distance of the support and the lateral distance of the roadway are matched. The hydraulic telescopic cylinder 18 is controlled to raise the lifting rod 19, so that the overall support can be matched with the height of the roadway.

[0055] Example 2:

[0056] like Figure 5As shown, the only difference between this embodiment and Embodiment 1 is that the length of the two sliding rods 3 is increased, and several telescopic components 2 can be fitted on the sliding rods 3, which increases the support length of the top surface and improves the support capacity for long roadways crossing faults.

[0057] Example 3:

[0058] like Figure 6 As shown, the difference between this embodiment and Embodiments 1 and 2 is that the telescopic support rod 1 includes an outer cylinder 25 and an inner rod 26. The inner rod 26 is slidably connected inside the outer cylinder 25. A rotating motor 27 is fixedly connected to the side wall of the outer cylinder 25. A first gear 28 is fixedly connected to the output end of the rotating motor 27. A rotating groove 34 is opened at the bottom of the side wall of the outer cylinder 25. The first gear 28 passes through the rotating groove 34 and meshes with a second gear 29. The second gear 29 is rotatably connected to the bottom surface of the inner cavity of the outer cylinder 25. One end of a screw 30 is fixedly connected to the top surface of the second gear 29. A screw hole 31 is opened on the bottom surface of the inner rod 26. The screw 30 and the screw hole 31 are threadedly connected. An abutment hole 32 is opened on the outer wall of the outer cylinder 25. An abutment block 33 is threadedly connected to the abutment hole 32. The abutment block 33 and the inner rod 26 are in contact with each other.

[0059] By turning on the rotating motor 27, the first gear 28 and the second gear 29 are driven to rotate, thus realizing the rotation of the screw 30. During the rotation of the screw 30, the inner rod 26 moves up and down in the inner cavity of the outer cylinder 25. At the same time, the height of the inner rod 26 can be fixed by manually tightening the abutment block 33.
