Description

Technical Field

[0001] The invention relates to the technical field of mine cave anti-collapse, and in particular to a mine cave anti-collapse top support device based on coal mining. Background Art

[0002] Coal mining is a complex engineering activity, involving geological exploration, mine design, mining technology, ventilation systems, safety measures and other aspects. In the process of coal mining, the stability of the mine is a very important issue. In order to prevent the top of the mine from collapsing and ensure the safety of operations, it is usually necessary to support the top of the mine to reduce the pressure of the surrounding rock and prevent collapse. In the prior art, the top of the mine is usually supported by building a support in the mine so that the support is in contact with the top of the mine. However, since the support is time-consuming and labor-intensive to build, and it is not convenient to disassemble, move and adjust the position of the support after construction, the efficiency of mine cave anti-collapse construction is low.

[0003] Therefore, a mine cave anti-collapse roof support device based on coal mining has been developed, which can quickly and conveniently support the mine cave top and improve the efficiency of mine cave anti-collapse construction. Summary of the invention

[0004] In order to overcome the shortcomings that the construction of mine tunnel anti-collapse roof support brackets is time-consuming and labor-intensive, and it is inconvenient to disassemble, move and adjust the position of the support after construction, resulting in low efficiency of mine tunnel anti-collapse construction, the present invention provides a mine tunnel anti-collapse roof support device based on coal mining, which can quickly and conveniently support the mine tunnel top and improve the efficiency of mine tunnel anti-collapse construction.

[0005] A mine cave anti-collapse roof support device based on coal mining comprises a support rod, a fixed support plate and a support mechanism. The upper and lower sides of the support rod are connected with fixed support plates. A support mechanism capable of supporting the mine cave top is arranged between the fixed support plate and the support rod.

[0006] Furthermore, the top support mechanism includes a sliding member, a connecting member, a connecting rod, a rotating support plate and an adjusting member. The sliding members are sleeved on the upper and lower parts of the support rod, the connecting members are connected to connecting members on both sides of the sliding member, the connecting members are rotatably connected to the connecting rods, the rotating support plates are rotatably connected to the left and right sides of the fixed support plates, the rotating support plates are rotatably connected to the adjacent connecting rods, the adjusting members are threadedly connected to the upper and lower parts of the support rod, the adjusting members are rotatably connected to the adjacent sliding members, and the rotating adjusting members are rotated to move the sliding members away from each other, driving the connecting members to move, so that the connecting rods push the rotating support plates to rotate to a horizontal state and contact the bottom and top of the mine respectively.

[0007] Furthermore, it also includes an expansion mechanism, which includes a fixed plate, a sliding plate, a sliding frame, a screw rod, a rotating rod, a first pull rope and a fixed ring.

[0008] Furthermore, an adaption mechanism is also included, which includes a telescopic sleeve, a spring, a buffer plate and an adaption member. A plurality of telescopic sleeves are connected to the lower side of the lower fixed plate, and buffer plates are connected between the telescopic ends of the telescopic sleeves connected to the same fixed plate. Springs are connected between the buffer plates and the connected telescopic sleeves, and a plurality of adaption members are connected to the lower side of the buffer plates. When the lower fixed plate contacts the bottom of the mine tunnel, the adaption member is inserted into the bottom of the mine tunnel so that the buffer plate is fixed to the ground at the bottom of the mine tunnel. When the ground at the bottom of the mine tunnel is uneven, the raised part of the ground squeezes the buffer plate to move upward, and the telescopic sleeve at the corresponding position contracts, and the spring is squeezed and contracted accordingly.

[0009] Furthermore, it also includes an radian mechanism, which includes a cylinder, a top plate, a fixed seat, a flip plate, a torsion spring, an extension plate, a wire rack and a second pull rope. The upper side of the upper fixed support plate is detachably connected to the cylinder by multiple bolts, and the telescopic end of the cylinder is connected to the top plate.

[0010] Furthermore, it also includes a stabilizing mechanism, which includes a fixing part and an insertion rod. The front and rear sides of the lower fixed support plate are connected to two left and right fixing parts, and the insertion rod is threadedly connected to the fixing part.

[0011] Furthermore, the lower part of the insertion rod is tapered.

[0012] Furthermore, a rotating head is also included, and the upper side of the insertion rod is connected to the rotating head.

[0013] Furthermore, it also includes a limiting mechanism, which includes a support rod and a locking plate. The left and right sides of the fixed ring are connected to the support rods, and the locking plates are connected to the support rods through damping rotation. When the fixed support plate is in a vertically retracted state, the locking plate is rotated to rotate the locking plate to a vertical state.

[0014] Furthermore, the lock plates are all provided with handles.

[0016] 2. The present invention drives the fixed plate to contact the mine cave when the rotating support plate contacts the bottom and top of the mine cave respectively.

[0017] 3. When the fixing plate on the lower side of the present invention contacts the bottom of the mine cave, the adaptor is inserted into the bottom of the mine cave, so that the buffer plate is fixed to the ground at the bottom of the mine cave. When the ground at the bottom of the mine cave is uneven, the raised part of the ground squeezes the buffer plate to move upward, and the telescopic sleeve at the corresponding position contracts, and the spring is squeezed and contracted accordingly, thereby achieving the effect of being able to adapt to the uneven bottom of the mine cave and ensuring the stability of the device.

[0018] 4. The present invention starts the cylinder to push the top plate upward, so that the top plate pushes the flip plate and the extension plate to rotate and open until they are in contact with the top of the mine cave, thereby achieving the effect of supporting the tops of different mine caves to meet the protection needs of different mine caves.

[0019] 5. The present invention rotates the insertion rod by turning the head to insert the insertion rod into the rock mass and fix the fixing member on the surface of the rock mass, thereby achieving the effect of fixing the fixed support plate on the bottom of the mine and avoiding displacement of the fixed support plate.

[0020] 6.

DETAILED DESCRIPTION

[0030] The present invention will now be described more fully below with reference to the accompanying drawings, in which currently preferred embodiments of the present invention are shown. However, the present invention may be implemented in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness, and these embodiments fully convey the scope of the present invention to the skilled person.

[0031] A mine cave anti-collapse roof support device based on coal mining, such as Figure 1 and Figure 2As shown, it includes a support rod 1, a fixed support plate 2 and a top support mechanism 3. The upper and lower sides of the support rod 1 are connected to the fixed support plate 2, and the top support mechanism 3 is provided between the fixed support plate 2 and the support rod 1.

[0032] like Figure 1 and Figure 3 As shown, the supporting mechanism 3 includes a sliding member 31, a connecting member 32, a connecting rod 33, a rotating supporting plate 34 and an adjusting member 35. The sliding member 31 is sleeved on the upper and lower parts of the supporting rod 1. The connecting member 32 is connected to the left and right sides of the sliding member 31. The connecting rod 33 is rotatably connected to the connecting member 32. The rotating supporting plates 34 are rotatably connected to the adjacent connecting rods 33 on the left and right sides of the fixed supporting plate 2. The rotating supporting plates 34 are rotatably connected to the adjacent connecting rods 33. The adjusting members 35 are threadedly connected to the upper and lower parts of the supporting rod 1. The adjusting members 35 are rotatably connected to the adjacent sliding members 31.

[0033] When using the present invention, first move the support rod 1 to a specified position in the mine cave, so that the fixed support plate 2 contacts the bottom and top of the mine cave respectively, and then rotate the adjusting member 35 to move the sliding members 31 away from each other, drive the connecting member 32 to move, so that the connecting rod 33 pushes the rotating support plate 34 to rotate to a horizontal state and contact the bottom and top of the mine cave respectively, thereby playing a role in quickly and conveniently supporting the top of the mine cave and improving the efficiency of mine cave anti-collapse construction.

[0034] like Figure 1 and Figure 4 As shown, it also includes an expansion mechanism 4, which includes a fixed plate 41, a sliding plate 42, a sliding frame 43, a screw rod 44, a rotating rod 45, a first pull rope 46 and a fixed ring 47. The front and rear sides of the rotating support plate 34 are connected to the fixed plates 41, the sliding plates 42 are slidably connected to the fixed plates 41, the upper sides of the sliding plates 42 are connected to the sliding frames 43, the sliding frames 43 are slidably connected to the adjacent fixed plates 41, the sliding frames 43 are threadedly connected to the screw rods 44, the middle part of the rotating support plate 34 is rotatably connected to the rotating rods 45, the screw rods 44 are connected to the adjacent rotating rods 45, the front and rear parts of the rotating rod 45 are wrapped with the first pull rope 46, the middle part of the support rod 1 is connected to the fixed ring 47, and the first pull rope 46 is connected to the fixed ring 47.

[0035] By using the expansion mechanism 4 of the present device, the support area of ​​the rotating support plate 34 can be expanded. When the rotating support plate 34 contacts the bottom and top of the mine respectively, it drives the fixed plate 41 to contact the mine. When the rotating support plate 34 rotates to a horizontal state, the first pull rope 46 is extended, pulling the rotating rod 45 to rotate, causing the screw rod 44 to rotate, thereby causing the sliding frame 43 to move away from each other, driving the sliding plate 42 to move away from each other, extending the area of ​​the fixed plate 41, thereby expanding the support area of ​​the rotating support plate 34 and improving the supporting effect on the top of the mine. When the rotating support plate 34 is rotated to a vertical state and retracted, a wrench is used to rotate the screw rod 44 to retract the sliding plate 42 into the fixed plate 41. While the screw rod 44 rotates, it drives the rotating rod 45 to rotate to retract the first pull rope 46.

[0036] like Figure 1 and Figure 5 As shown, an adaption mechanism 5 is also included, and the adaption mechanism 5 includes a telescopic sleeve 51, a spring 52, a buffer plate 53 and an adaption member 54. Eight telescopic sleeves 51 are connected to the lower side of the lower fixed plate 41, and buffer plates 53 are connected between the telescopic ends of the telescopic sleeves 51 connected to the same fixed plate 41. Springs 52 are connected between the buffer plates 53 and the connected telescopic sleeves 51, and fifteen adaption members 54 are connected to the lower side of the buffer plates 53.

[0037] The adaptability mechanism 5 of the device can adapt to the uneven bottom of a mine. When the lower fixing plate 41 contacts the bottom of the mine, the adaptability member 54 is inserted into the bottom of the mine, so that the buffer plate 53 is fixed to the ground at the bottom of the mine. When the ground at the bottom of the mine is uneven, the raised part of the ground squeezes the buffer plate 53 to move upward, and the telescopic sleeve 51 at the corresponding position contracts, and the spring 52 is squeezed and contracted accordingly, thereby being able to adapt to the uneven bottom of the mine and ensuring the stability of the device.

[0038] like Figure 1 and Figure 6As shown, it also includes an arc mechanism 6, which includes a cylinder 61, a top plate 62, a fixed seat 63, a flip plate 64, a torsion spring 65, an extension plate 66, a wire rack 67 and a second pull rope 68. The upper side of the upper fixed support plate 2 is detachably connected to the cylinder 61 through six bolts, and the top plate 62 is connected to the telescopic end of the cylinder 61. The upper rotating support plate 34 is detachably connected to the fixed seat 63 on one side away from the fixed support plate 2 through four bolts, and the fixed seat 63 is rotatably connected to The flip plate 64 and the top plate 62 are both in contact with the flip plate 64. Two front and rear torsion springs 65 are connected between the flip plate 64 and the connected fixed seat 63. Extension plates 66 are connected to the front and rear sides of the flip plate 64. The upper rotating support plate 34 is detachably connected to a wire rack 67 on one side close to the fixed support plate 2 through four bolts. The front and rear parts of the flip plate 64 are both wrapped with a second pull rope 68. The second pull rope 68 is in contact with the adjacent wire rack 67 and is connected to the top plate 62.

[0039] The arc mechanism 6 of the present device can be used to support the roofs of different mine caves. When the top of the mine cave is arc-shaped, the arc mechanism 6 is installed on the fixed support plate 2 and the rotating support plate 34 on the upper side by bolts, and then the cylinder 61 is started to push the top plate 62 to move upward, so that the top plate 62 pushes the flip plate 64 and the extension plate 66 to rotate and open until they are in contact with the top of the mine cave, thereby supporting the roofs of different mine caves to meet the protection needs of different mine caves. The torsion spring 65 is deformed, and the top plate 62 moves upward while pulling the second pull rope 68. The wire frame 67 limits and guides the second pull rope 68, thereby further improving the stability of the flip plate 64. After the top plate 62 moves downward and resets, the torsion spring 65 recovers, driving the flip plate 64 to rotate and reset.

[0040] like Figure 1 and Figure 7 As shown, a stabilizing mechanism 7 is also included, which includes a fixing member 71, an insert rod 72 and a rotating head 73. The front and rear sides of the lower fixed support plate 2 are connected to the left and right fixing members 71, and the fixing members 71 are threadedly connected to the insert rods 72. The lower parts of the insert rods 72 are all tapered to facilitate insertion and fixing, and the upper sides of the insert rods 72 are connected to the rotating heads 73.

[0041] By using the stabilizing mechanism 7 of the device, the fixed support plate 2 can be fixed to the bottom of the mine. By rotating the insertion rod 72 by turning the head 73, the insertion rod 72 is inserted into the rock mass, and the fixing part 71 is fixed to the surface of the rock mass, thereby fixing the fixed support plate 2 to the bottom of the mine and preventing the fixed support plate 2 from shifting.

[0042] like Figure 1 and Figure 8As shown, it also includes a limiting mechanism 8, which includes a support rod 81 and a locking plate 82. The left and right sides of the fixed ring 47 are connected to the support rods 81, and the support rods 81 are connected to the locking plates 82 through damping rotation. The locking plates 82 are provided with handles for easy rotation. When the fixed support plate 2 is in a vertically retracted state, the locking plate 82 is rotated to rotate to a vertical state.

[0043] By using the limiting mechanism 8 of the device, the fixed support plate 2 can be limited. When the fixed support plate 2 is in a vertically retracted state, the locking plate 82 is rotated to rotate the locking plate 82 to a vertical state, thereby limiting the fixed support plate 2 and preventing the fixed support plate 2 from shaking during transportation.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
