Description

Technical Field

[0001] This invention relates to the field of tunnel support technology, specifically a high-gas tunnel support device. Background Technology

[0002] In high-gas environments, coal is softened and weakened by gas infiltration, and fissures are easily opened by gas pressure. When rock bursts occur, the enormous impact force generated by the instantaneous and violent destruction of the rock mass changes the topographic structure and accelerates the desorption and release of gas from micropores into the roadway space. The two promote each other and create a vicious cycle, which not only increases the risk of gas explosion exceeding the limit but also exacerbates the probability of roof instability, significantly increasing the complexity of the roadway environment.

[0003] Existing technologies mostly employ passive support methods using anchor bolts, anchor cables, and metal mesh or steel strips to control the roof. This type of support uses anchors to form a whole with the surrounding rock and the support structure. It can initially restrain the deformation of shallow rock strata, but it is not adaptable to high gas impact environments. Continuous gas infiltration weakens the bonding performance of the anchoring agent, and the dynamic stress caused by the impact pressure can easily lead to anchor bolt breakage or tray failure. Furthermore, it is difficult to seal the gas escape channels formed by the expansion of cracks in time, often resulting in excessive roof settlement, local roof leakage, or even abnormal gas outbursts.

[0004] Existing support devices mostly use a combination of anchor bolts and U-shaped supports to achieve the support effect. However, under the combined effects of gas and rock bursts, the degree of fracture of the roadway roof will be higher, and irregular protrusions are prone to occur. The conventional combination of U-shaped supports and anchor bolts is difficult to provide good support for irregular protrusions and is not suitable for such roadway environments. Summary of the Invention

[0005] In view of this, a high-gas roadway support device is proposed to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a high-gas roadway support device, comprising a support frame, and further comprising:

[0007] A mounting slot is provided at the top of the bracket;

[0008] A limiting rod is provided in the mounting groove to install the support assembly and limit the movement trajectory of the support assembly;

[0009] A support assembly, mounted on the limiting rod, is used to support the top of the tunnel;

[0010] The support assembly includes a collar, which is slidably mounted on the limiting rod. An installation rod is fixedly mounted on the collar, a fixing plate is fixedly mounted on the installation rod, a connecting block is fixedly mounted on the fixing plate, a connecting seat is provided on the connecting block, a connecting sleeve is provided on the connecting seat, an installation plate is fixedly mounted on the connecting sleeve, and a support block is fixedly mounted on the installation plate.

[0011] Preferably, multiple sets of the support components are provided and symmetrically arranged on both sides of the limiting rod.

[0012] Preferably, the connecting seat is a spherical mounting seat, and the connecting sleeve is rolled on the connecting seat.

[0013] Preferably, an adjusting component is fixedly installed on the mounting rod. The adjusting component includes a connecting rod, which is rotatably connected to the mounting rod. A fixing rod is fixedly installed at the end of the connecting rod away from the mounting rod, and a hinge seat is hinged at the end of the fixing rod away from the connecting rod. The hinge seat is fixedly installed on the side wall of the mounting groove.

[0014] Preferably, a synchronizing element is fixedly installed at the end of the mounting rod away from the fixed plate. The synchronizing element includes a mounting block, which is fixedly connected to the mounting rod. A rotating shaft is provided at the end of the mounting block away from the mounting rod. The rotating shaft is fixedly installed on the side wall of the mounting groove and is rotatably connected to the mounting block.

[0015] Preferably, a plurality of display meters are fixedly installed on the side of the bracket away from the mounting groove. Each display meter includes a dial, a scale is fixedly installed inside the dial, a pointer is rotatably installed at the center of the dial, and a glass partition is provided on the dial.

[0016] Preferably, a drive gear is fixedly mounted on the side of the mounting block near the rotating shaft, and a driven gear is rotatably mounted on the side wall of the mounting groove, with the drive gear and the driven gear meshing.

[0017] Preferably, the driven gear is fixedly connected to the pointer.

[0018] Preferably, when the support components on this device are not triggered, the distance between adjacent support components is 15-20cm, and the length of each segment of the limiting rod is 45-60cm.

[0019] Preferably, the support block is made of a flexible material.

[0020] Compared with the prior art, the present invention provides a support device for high-gas roadways, which has the following beneficial effects:

[0021] 1. This invention, through the cooperation of a limiting rod and a support component, when an irregular protrusion appears at the top of the tunnel, will squeeze the support block on the support component. The spherical connecting seat will deflect under external pressure, causing the connecting sleeve to rotate at a certain angle, thus providing adaptive support for the irregular protrusion. This solves to some extent the problem that conventional supports cannot handle irregular protrusions, and does not require large-scale modification of commonly used supports, thus taking into account practicality and economic benefits and improving protection capabilities.

[0022] 2. Through the cooperation of the adjusting and synchronizing components, this invention addresses the issue that when the irregular protrusion is large, the close proximity of adjacent support blocks hinders its support. In this case, the adjacent support blocks move relative to each other, increasing the distance between them. This creates a lever structure between the adjacent support blocks and the protrusion, increasing the torque and allowing support blocks of the same strength to support heavier protrusions. This reduces the probability of damage to the support blocks when a protrusion occurs and improves the support effect.

[0023] 3. This invention, through the cooperation of the display and driven gear, allows for observation of protrusions during routine inspections when the support block moves. Since the movement occurs at the top of the support, it is difficult to observe the protrusions during routine inspections. However, when the support block moves, the synchronizing element rotates, and since the driving gear and driven gear are proportional, even minor movements can be observed through the display. This improves the observation effect while reducing the labor intensity of workers climbing up and down or looking up to observe. At the same time, it also amplifies minute displacements, improving the accuracy of observation. Attached Figure Description

[0038] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, some features described in the examples may be combined in other examples.

[0039] like Figures 1 to 9 As shown, an embodiment of the present invention provides a support device for high-gas roadways, including a support frame 1, and further comprising:

[0040] Mounting slot 2 is provided on the top of bracket 1;

[0041] The limiting rod 3 is set in the mounting groove 2 to install the support component 4 and limit the movement trajectory of the support component 4;

[0042] Support component 4 is mounted on limit rod 3 and is used to support the top of the tunnel;

[0043] The support assembly 4 includes a collar 41, which is slidably mounted on the limiting rod 3. An installation rod 42 is fixedly mounted on the collar 41. A fixing plate 43 is fixedly mounted on the installation rod 42. A connecting block 44 is fixedly mounted on the fixing plate 43. A connecting seat 45 is provided on the connecting block 44. A connecting sleeve 46 is provided on the connecting seat 45. An installation plate 47 is fixedly mounted on the connecting sleeve 46. A support block 48 is fixedly mounted on the installation plate 47.

[0044] The working principle and beneficial effects of the above technical solution are as follows: When the device is installed at the location in the roadway that needs support, the support component 4 is in close contact with the roadway roof. When a small irregular protrusion appears on the roadway roof, the support component 4 will not move on the limit rod 3. At this time, the squeezing action of the irregular protrusion will squeeze the support block 48, and the connecting sleeve 46 below the support block 48 will deflect on the connecting seat 45, thus supporting the irregular protrusion.

[0045] In one embodiment, multiple sets of support components 4 are provided and symmetrically arranged on both sides of the limiting rod 3.

[0046] The working principle and beneficial effects of the above technical solution are as follows: since multiple sets of support components 4 are provided, the tunnel roof and irregular protrusions can be supported at multiple points, reducing the force on each support component 4 and reducing the probability of damage to the support component 4.

[0047] In one embodiment, the connector 45 is a spherical mounting base, and the connector sleeve 46 is rolled on the connector 45.

[0048] The working principle and beneficial effects of the above technical solution are as follows: the connecting seat 45 is fixedly installed on the connecting block 44 and is rotatably connected to the connecting sleeve 46. When the support block 48 is squeezed, the connecting sleeve 46 will rotate on the connecting seat 45, which can adapt to different protrusions of irregular protrusions.

[0049] In one embodiment: an adjusting member 49 is fixedly installed on the mounting rod 42. The adjusting member 49 includes a connecting rod 491, which is rotatably connected to the mounting rod 42. A fixing rod 492 is fixedly installed at the end of the connecting rod 491 away from the mounting rod 42. A hinge seat 493 is hinged at the end of the fixing rod 492 away from the connecting rod 491. The hinge seat 493 is fixedly installed on the side wall of the mounting groove 2.

[0050] The working principle and beneficial effects of the above technical solution are as follows: When the irregular protrusion has a large volume, the support component 4 will move on the limiting rod 3. At this time, the adjusting component 49 will also move synchronously. When the adjusting component 49 moves, it will drive the connecting rod 491 to rotate, which in turn will drive the fixed rod 492 to rotate on the hinge seat 493.

[0051] In one embodiment: a synchronizing element 6 is fixedly installed at the end of the mounting rod 42 away from the fixed plate 43. The synchronizing element 6 includes a mounting block 61, which is fixedly connected to the mounting rod 42. A rotating shaft 62 is provided at the end of the mounting block 61 away from the mounting rod 42. The rotating shaft 62 is fixedly installed on the side wall of the mounting groove 2 and is rotatably connected to the mounting block 61.

[0052] The working principle and beneficial effects of the above technical solution are as follows: When the adjusting component 49 is used, when the support component 4 moves, it will drive the mounting block 61 to rotate on the rotating shaft 62. Since the support component 4 is composed of two symmetrical parts, both of which rotate on the rotating shaft 62, when one part of the support component 4 rotates, the two parts of the support component 4 are adjusted synchronously with the cooperation of the adjusting component 49 and the synchronizing component 6, so that the distance between them increases simultaneously. A lever structure is formed between the adjacent support blocks 48 and the protrusion. Increasing the distance between the support blocks 48 can increase the torque, allowing the support blocks 48 of the same strength to support a heavier protrusion. This reduces the probability of the support blocks 48 being damaged when a protrusion occurs to a certain extent, and improves the support effect.

[0053] In one embodiment: a plurality of display meters 5 are fixedly installed on the side of the bracket 1 away from the mounting groove 2. The display meters 5 include a dial 51, a scale 52 is fixedly installed inside the dial 51, a pointer 53 is rotatably installed at the center of the dial 51, and a glass partition is provided on the dial 51.

[0054] The working principle and beneficial effects of the above technical solution are as follows: the glass partition on the display table 5 can prevent dust in the tunnel from entering the display table 5 and jamming the pointer 53. In addition, the scale 52 on the display table 5 is made of fluorescent material. Since the lighting environment in the tunnel is not very good, by setting the scale 52 of fluorescent material, it is easier for the staff to observe the indication of the pointer 53 of the display table 5, thus improving the visibility.

[0055] In one embodiment: a drive gear 63 is fixedly mounted on the side of the mounting block 61 near the rotating shaft 62, and a driven gear 64 is rotatably mounted on the side wall of the mounting groove 2, with the drive gear 63 and the driven gear 64 meshing.

[0056] The working principle and beneficial effects of the above technical solution are as follows: When the support component 4 rotates, it will drive the mounting block 61 to rotate, thereby driving the drive gear 63 to rotate, and then driving the driven gear 64 to rotate. Since the drive gear 63 and the driven gear 64 are proportional, and the volume of the drive gear 63 is larger than that of the driven gear 64, even when there is a small movement, it can be observed through the display table 5. This improves the observation effect and reduces the labor intensity of the staff who have to climb up and down or look up to observe. At the same time, it also magnifies the small displacement and improves the accuracy of the observation.

[0057] In one embodiment, the driven gear 64 is fixedly connected to the pointer 53.

[0058] The working principle and beneficial effects of the above technical solution are as follows: when the driven gear 64 rotates, it will drive the pointer 53 to rotate.

[0059] In one embodiment: when the support component 4 on this device is not triggered, the distance between adjacent support components 4 is 15-20cm, and the length of each limiting rod 3 is 45-60cm.

[0060] The working principle and beneficial effects of the above technical solution are as follows: When in the initial state, since the condition of the top of the roadway is good, the support component 4 is adjusted to a suitable position that needs support. At this time, the distance between adjacent support components 4 is small, and the support effect of the position that needs to be fixed is good. When the irregular protrusion causes the support component 4 to move, the distance between adjacent support components 4 on the limit rod 3 will increase. A lever structure is formed between the adjacent support block 48 and the protrusion. Increasing the distance between the support blocks 48 can increase the torque, so that the support block 48 of the same strength can support a heavier protrusion. To a certain extent, the probability of the support block 48 being damaged when the protrusion occurs is reduced, and the support effect is improved.

[0061] In one embodiment, the support block 48 is made of a flexible material.

[0062] The working principle and beneficial effects of the above technical solution are as follows:

[0063] Working principle and usage process: Install this device at the location in the roadway that requires support, so that the support component 4 is in close contact with the roadway roof. When a small irregular protrusion appears on the roadway roof, the support component 4 will not move on the limit rod 3. At this time, the squeezing action of the irregular protrusion will squeeze the support block 48, and the connecting sleeve 46 below the support block 48 will deflect on the connecting seat 45, thus supporting the irregular protrusion. Since there are multiple sets of support components 4, the roadway roof and irregular protrusion can be supported at multiple points, reducing the force on each support component 4 and reducing the probability of damage to the support component 4.

[0064] When the irregular protrusion is large, the support component 4 will move on the limit rod 3. At this time, the adjusting component 49 will also move synchronously. When the adjusting component 49 moves, it will drive the connecting rod 491 to rotate, which in turn will drive the fixed rod 492 to rotate on the hinge seat 493.

[0065] Based on the above, when the support assembly 4 moves, the mounting block 61 will rotate on the rotating shaft 62 when the adjusting component 49 is used. Since the support assembly 4 is composed of two symmetrical parts, both of which rotate on the rotating shaft 62, when one part of the support assembly 4 rotates, the two parts of the support assembly 4 are adjusted synchronously with the cooperation of the adjusting component 49 and the synchronizing component 6, so that the distance between them increases simultaneously. A lever structure is formed between the adjacent support blocks 48 and the protrusion. Increasing the distance between the support blocks 48 can increase the torque, allowing the support blocks 48 of the same strength to support a heavier protrusion. This reduces the probability of the support blocks 48 being damaged when the protrusion occurs to a certain extent, and improves the support effect.

[0066] In addition, the glass partition on the display 5 can prevent dust in the tunnel from entering the display 5 and jamming the pointer 53. Furthermore, the scale 52 on the display 5 is made of fluorescent material. Since the lighting environment in the tunnel is not very good, by setting the scale 52 of fluorescent material, it is easier for staff to observe the indication of the pointer 53 on the display 5, thus improving the visibility.

[0067] Furthermore, when the support component 4 rotates, it will drive the mounting block 61 to rotate, thereby driving the drive gear 63 to rotate, which in turn drives the driven gear 64 to rotate. Since the drive gear 63 and the driven gear 64 are proportional, and the volume of the drive gear 63 is larger than that of the driven gear 64, even when there is a small movement, it can be observed through the display table 5. This improves the observation effect and reduces the labor intensity of staff climbing up and down or looking up to observe. At the same time, it also magnifies the small displacement and improves the accuracy of the observation.

[0068] When in the initial state, since the top of the tunnel is in good condition, the support component 4 is adjusted to the appropriate position that needs support. At this time, the distance between adjacent support components 4 is small, and the support effect of the fixed position is good. When the irregular protrusion causes the support component 4 to move, the distance between adjacent support components 4 on the limit rod 3 will increase. A lever structure is formed between the adjacent support block 48 and the protrusion. Increasing the distance between the support blocks 48 can increase the torque, so that the support block 48 of the same strength can support a heavier protrusion. This reduces the probability of the support block 48 being damaged when the protrusion occurs to a certain extent, and improves the support effect.

[0069] Finally, the material of the support block 48 can be selected according to the specific conditions of the tunnel. It can be made of high-strength resin or polymer composite fiber.

[0070] The embodiments of the present invention have been described above, but the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments described above, all of which are within the protection scope of the embodiments described above.
