Description

Technical Field

[0001] The utility model relates to the field of coal seam roadway support devices, and particularly to a roadway support device for deep and closely spaced inclined coal seams. Background Art

[0002] The coal seam roadway support device is an important facility for protecting the safety of coal mine roadways. Its main function is to bear the rock pressure, prevent the roadway from collapsing, and ensure the safe operation of miners. Common support methods include steel supports, concrete supports, and bolt supports, etc. These devices can effectively disperse and transfer the formation pressure, adapt to different geological conditions, and improve the stability and service life of the roadway. With the progress of technology, modern support devices are gradually developing towards the direction of intelligence and automation to improve safety and work efficiency.

[0003] After retrieval, the Chinese patent "A Mining Support Device for Coal Seam Roadways" with the authorization announcement number "CN216342232U" is a mining support device for coal seam roadways, including a protective cover. There are protrusions at the bottom of the protective cover, and legs are provided at the bottom of the protective cover. A support beam is provided between the tops of each pair of legs. Threaded holes are opened at the lower ends of the legs. Support boxes are provided below each leg. A bearing seat is fixed at the inner bottom end of the support box. A bearing is assembled in the bearing seat, and a support column is assembled in the bearing. The top of the support column is fixed with a vertically arranged adjusting lead screw. The upper end of the adjusting lead screw extends out of the support box, and the upper end of the adjusting lead screw is threadedly connected to the lower end of the leg. A vertically arranged first bevel gear is provided on the support column. One side of the support box is rotatably assembled with a crank by a bearing. One end of the crank extends into the support box and is fixed with a horizontally arranged second bevel gear. The first bevel gear and the second bevel gear mesh with each other. The utility model has a simple structure and is convenient to use.

[0004] Although the above-mentioned roadway support device for coal seam mining has the effect of adjusting the height of the support device and the "K"-shaped support frame can provide support for the overall device, there are multiple adjusting structures at the bottom of the entire support device, and each adjusting structure is an independent adjustment. Therefore, when debugging, unless multiple personnel debug together, it is easy to occur that the height of the overall device is inconsistent during debugging, resulting in the device tilting and reducing the support effect. At the same time, the range of the overall support device cannot be adjusted, which also means that it cannot be used for roadways of different widths.

[0005] Therefore, a roadway support device for deep and closely spaced inclined coal seams is proposed to solve the above problems. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a roadway support device for deep and closely spaced inclined coal seams in order to solve the above problems, improving the problem that the height adjustment method of the traditional roadway support device for coal seam mining is not simple enough and cannot be used for roadways of different widths, having certain limitations.

[0007] The present utility model realizes the above purpose through the following technical solutions. A roadway support device for deep and closely spaced inclined coal seams includes: an adjusting seat for adjusting the overall height of the support device. A lead screw is arranged inside the adjusting seat, and an adjusting plate is threadedly connected to the surface of the lead screw.

[0008] A support component capable of supporting roadways of different widths is arranged between the two adjusting plates.

[0009] Among them, the support component includes two connecting plates. One side of each of the two connecting plates, which is opposite to the other, is fixedly connected to the adjusting plate. A limiting plate is fixedly connected between the two sides of the two connecting plates that face each other. A support rod is movably connected to the lower surface of the limiting plate through a rotating shaft, and one end of the support rod away from the limiting plate is movably connected to the connecting plate through a rotating shaft. A guide rail is fixedly connected to the inner top wall of the support shell.

[0010] Preferably, the surface of the connecting plate is provided with a groove, and the rotating shaft at one end of the support rod close to the connecting plate is slidably connected to the inner wall of the groove. Through the above description, the bottom end of the support plate can be limited.

[0011] Preferably, a push rod is movably connected to the surface of the connecting plate through a rotating shaft, and the telescopic end of the push rod is movably connected to the surface of the support rod near the lower part through a rotating shaft. Through the push rod, the overall width of the support device can be adjusted by abutting against or driving the support rod to contract.

[0012] Preferably, both the limiting plate and the support shell are telescopic. The limiting plate is three-section telescopic, and the support shell is arched and two-section telescopic. Through the above description, the support area of the support device can be adjusted.

[0013] Preferably, a connecting block is arranged at the inner top of the support shell. A sliding seat is fixedly connected to the surface of the connecting block, and the surface of the sliding seat is slidably connected to the inner cavity of the guide rail. Through the sliding seat, the connecting block can be limited to compensate for the angular change of the auxiliary plate.

[0014] Preferably, the number of the connecting blocks is two. An auxiliary plate is movably connected between the two sides of the two connecting blocks that face each other through a rotating shaft. Through the auxiliary plate, corresponding angular changes can be made according to the height difference between two support devices, ensuring the connectivity of the device and not affecting the height of other support devices or causing the phenomenon of other support devices tilting.

[0015] Preferably, the two connecting plates and the auxiliary plate are bendable, and the maximum bending angle between the connecting plate and the auxiliary plate is ninety degrees.

[0016] The beneficial effects of the present utility model are as follows:

[0017] 1. By providing a separate support component, when the staff adjusts the height of the support device, the height compensation of the two support plates at different heights can be achieved by bending the connecting block and the auxiliary plate. At the same time, it can also avoid the phenomenon of overall inclination caused by the adjustment of one end of the support device, and effectively maintain the connectivity and debugging convenience of multiple support devices;

[0018] 2. Through the push rod, the support rod, the telescopic limiting plate and the support shell in the support component, the support area of the support device can be adjusted correspondingly for coal seam mining roadways with different widths to achieve the effect of fitting support. At the same time, it can also ensure the support effect of the roadway, and improve the adaptability and practicality of the overall support device. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Specifically implemented as: As Figures 1-4As shown in the figure, a roadway support device for deep and closely spaced inclined coal seams includes an adjusting base 1 for adjusting the overall height of the support device. A lead screw 2 is arranged inside the adjusting base 1, and an adjusting plate 3 is threadedly connected to the surface of the lead screw 2; a support assembly 4 capable of supporting roadways of different widths is arranged between the two adjusting plates 3;

[0026] It should be noted that: the internal components and working principle of the above-mentioned adjusting base 1 are the same as the debugging method of the Chinese patent "A Mining Support Device for Coal Seam Roadways" with the authorization announcement number "CN216342232U". Both are to make the first bevel gear at the rotating shaft of the crank rotate to engage the second bevel gear on the surface of the lead screw 2 to rotate, and then the lead screw 2 can be rotated to make the entire support assembly 4 rise through the adjusting plate 3;

[0027] It should be noted that: when the staff adjusts the height of the support assembly 4, they need to hold the cranks of the two adjusting bases 1 with both hands at the same time, and then shake the two rockers synchronously. In this way, it can ensure that the support assembly 4 rises in a horizontal state;

[0028] As Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown in the figure, the support assembly 4 includes two connecting plates 401. On the opposite sides of the two connecting plates 401, they are both fixedly connected to the adjusting plate 3. A limiting plate 402 is fixedly connected between the opposite sides of the two connecting plates 401. A support rod 404 is movably connected to the lower surface of the limiting plate 402 through a rotating shaft. One end of the support rod 404 away from the limiting plate 402 is movably connected to the connecting plate 401 through a rotating shaft. A guide rail 406 is fixedly connected to the inner top wall of the support shell 403;

[0029] The surface of the connecting plate 401 is provided with a groove. The rotating shaft of the support rod 404 near the connecting plate 401 slides on the inner wall of the groove; a push rod 405 is movably connected to the surface of the connecting plate 401 through a rotating shaft. The telescopic end of the push rod 405 is movably connected to the surface of the support rod 404 near the lower part through a rotating shaft; both the limiting plate 402 and the support shell 403 are telescopic. The limiting plate 402 is a three-section telescopic type, and the support shell 403 is in an arched shape and is a two-section telescopic type;

[0030] First, the push rod 405 is driven according to the width of the lane. When the push rod 405 extends outward and pushes the support rod 404, the support rod 404 will push the two connecting plates 401 to the opposite side. At this time, the support device as a whole will be stretched open and the support area will be expanded. Similarly, when encountering some narrow lanes, the two push rods 405 will pull the two support rods 404 relative to each other. At this time, the two connecting plates 401 will be relatively displaced, and the limit plate 402 and the support shell 403 will be relatively contracted. By debugging the adjustment seat 1 and the screw rod 2, the adjustment plate 3 will lower the support assembly 4 as a whole, so that it can be adapted to the lane.

[0031] A connecting block 408 is provided at the inner top of the support shell 403, and a sliding seat 407 is fixedly connected to the surface of the connecting block 408, and the surface of the sliding seat 407 is slidably connected to the inner cavity of the guide rail 406; there are two connecting blocks 408, and an auxiliary plate 409 is movably connected between the opposite sides of the two connecting blocks 408 through a rotating shaft; the two connecting plates 401 and the auxiliary plates 409 are bendable, and the maximum bending angle between the connecting plate 401 and the auxiliary plate 409 is ninety degrees;

[0032] When the staff is adjusting the height of the support device, when the height of the support device at one end is lowered or raised, the connecting block 408 will assist the auxiliary plate 409 between the two support devices through the corresponding extension and contraction of the slide seat 407 on the inner wall of the guide rail 406, and can change the angle with the auxiliary plate 409, so that the problem of affecting the horizontal height of the entire device during the adjustment of the support device can be prevented;

[0033] When the utility model is in use, when the staff needs to support the coal seam mining tunnel, firstly, the push rod 405 is driven according to the width of the tunnel. When the push rod 405 extends outward and pushes the support rod 404, the support rod 404 will push the two connecting plates 401 to the opposite side. At this time, the supporting device as a whole will be opened and the supporting area will be expanded. Similarly, when encountering some narrow tunnels, the two push rods 405 will pull the two support rods 404 relative to each other. At this time, the two connecting plates 401 will be relatively displaced, and the limit plate 402 and the support shell 403 will be The supporting assembly 4 is relatively contracted, and the adjusting plate 3 is lowered as a whole by debugging the adjusting seat 1 and cooperating with the screw rod 2 to adapt to the tunnel. When the staff adjusts the height of the supporting device, when the height of the supporting device at one end is lowered or raised, the connecting block 408 will assist the auxiliary plate 409 between the two supporting devices through the corresponding extension and contraction of the sliding seat 407 on the inner wall of the guide rail 406, and can change the angle of the auxiliary plate 409. In this way, the problem of affecting the horizontal height of the overall device during adjustment of the supporting device can be prevented.

[0034] In addition, it should be understood that although this specification is described according to embodiments, not every embodiment only contains an independent technical solution. This narrative way of the specification is only for clarity. Those skilled in the art should regard the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
