Description

Technical Field

[0001] The invention relates to the field of arch tunnel support, and in particular to an assembled support device. Background Art

[0002] At present, the basic support method for underground tunnels in coal mines is shed support. When facing arched tunnels, an arched support structure will be used. This structure is assembled from top beams, column legs, connectors and other components. It has good bearing capacity and can increase the stability of the coal seam, thereby effectively preventing accidents such as collapse and roof falls, and ensuring the safety of miners' lives.

[0003] At present, the traditional assembled arch support structure still has certain shortcomings during use: first, the commonly used arch support is mostly compression support. When the coal seam is pressed down, the top beam is deformed by force, thereby avoiding direct damage to the support structure. However, the traditional top beam structure has weak compressive resistance. When the top beam is slightly deformed, it is difficult for workers to find the coal seam pressure. Secondly, in some cases, due to roof collapse or underground coal mine operations, the support will fall down and fall apart. At this time, if there are people below, the support parts are easy to hit the workers' heads directly, causing more serious accidents;

[0004] In addition, the current assembled arch support structure is still difficult to fix with locking foot anchor rods, and workers are prone to installation crookedly or at substandard angles. Moreover, since the arch support is a passive support, backing material is generally set between the protective net and the bracket to achieve top connection, etc., to prevent the roof from delaminating. However, there are generally large gaps between the several woods serving as backing materials, which makes the force on various parts of the bracket uneven and cannot provide a good supporting effect on the coal seam.

[0005] Therefore, it is necessary to provide a new assembled support device to solve the above technical problems. Summary of the invention

[0006] The technical problem solved by the present invention is to provide an assembled support device with an anti-falling-away bracket that can prevent the bracket from falling directly, a top beam with good compressive resistance and the ability to monitor the deformation of the top beam, and secondly, the locking foot anchor rod is easy to install and convenient for top connection.

[0007] In order to solve the above technical problems, the present invention provides an assembled support device comprising: a column leg, a top beam, a pressure-bearing component and a support component, wherein the column leg is provided with two and is respectively located on the left and right sides of the top beam, and the surfaces of the column leg and the top beam are provided with a plurality of evenly distributed insertion holes, and the pressure-bearing component comprises a first fixing member, both side walls of the first fixing member are rotatably connected with a first threaded rod, the surface of the first threaded rod is threadedly connected with a first outer cylinder, the first outer cylinder is slidably connected to the first fixing member, the end of the first outer cylinder is fixedly connected with a pressure plate, the surface of the pressure plate is plugged with a second limiting block, the surface of the first fixing member located on one side of the pressure plate is plugged with a first limiting block, the surface of the first limiting block is rotatably connected with the second outer cylinder, the surface of the second limiting block is fixedly connected with a second threaded rod, and the second outer cylinder is threadedly connected to the second threaded rod;

[0008] The column legs and the top beam surfaces are fixedly connected with ear plates, the support assembly includes an outer rod, the outer rod is fixedly connected with an inner rod via a spring, the inner rod and the outer rod are slidably connected, both ends of the outer rod and the inner rod are plugged with first bolts, the two first bolts are respectively plugged with the ear plates on the top beam and the column legs, and the ends of the first bolts are threadedly connected with nuts.

[0009] As a further solution of the present invention, the tops of the two column legs are respectively located on the inner sides of the two ends of the top beam, and connecting parts are provided on the upper and lower sides of the ends of the top beam. The two connecting parts distributed up and down are fixedly connected by a second bolt and a fixing nut.

[0010] Through the above technical solution, the top of the column leg is arc-shaped and fits with the end of the top beam, and then the ends of the two structures are fixed together by the connecting piece, the second bolt and the fixing nut.

[0011] As a further solution of the present invention, auxiliary components are provided on one side of the top beam and the column leg, and the auxiliary components include a safety hook. The safety hook is arranged inside the insertion hole on one side of the top beam and the column leg, and a chain is arranged on the inner side of the safety hook, and the end of the chain is fixedly connected with a fixed anchor rod.

[0012] Through the above technical solution, in certain cases, due to roof collapse or underground coal mine operations, the support structure may topple or fall apart. At this time, if there are people below, the support components may easily hit the workers' heads directly, causing more serious accidents. The device has several sockets on the column legs and top beams. After the support device is installed, the user fixes the safety hook in the socket at the appropriate position and hooks the chain with the safety hook. The fixed anchor rods at the ends of the chain need to be fixed in the coal seams on both sides or the top. In this way, when the structural components fall apart or tilt due to an accident, the chain has a dragging effect, so it can be prevented from directly hitting the people or equipment below, thereby protecting the safety of personnel and facilities.

[0013] As a further solution of the present invention, the bottoms of the two column legs are fixedly connected to a base, a limiting assembly is arranged on the upper side of the base, the limiting assembly includes a second fixing member, the second fixing member is arranged on the outer side of the column leg, the left and right side walls of the second fixing member are fixedly connected to a guide member, the guide member is arranged at an angle and a locking foot anchor rod is arranged on the inner side of the guide member.

[0014] Through the above technical solution, the locking foot anchor rod is a component that needs to be installed immediately after the top beam and the column leg are installed. This structure can prevent the arch foot from shrinking and the arch from hanging. When installing the structure, the second fixing member can be fixed to the base at a suitable height using the second fixing bolt. Since the guide member and the column leg in the structure maintain a specified angle, it is more convenient and accurate for workers to drill holes, and it is also easier to fix the locking foot anchor rod.

[0015] As a further solution of the present invention, a second fixing bolt is inserted into the surface of the second fixing member, the second fixing bolt is inserted into the socket on one side of the column leg surface and a second limiting nut is threadedly connected to the end thereof, an opening is opened on one side surface of the guide member, and the locking foot anchor rod is welded to the guide member.

[0016] Through the above technical solution, after the rod body of the locking foot anchor rod is fixed inside the coal seam, the locking foot anchor rod and the guide piece can be fixed together from the opening, and the fixation is convenient and firm.

[0017] As a further solution of the present invention, a first fixing bolt is inserted into the surface of the first fixing member, the first fixing bolt is inserted into the insertion hole on one side of the column leg surface and a first limiting nut is threadedly connected to the end thereof.

[0018] Through the above technical scheme, since the arch support belongs to passive support, backing material is generally set between the protective net and the bracket to achieve top connection, etc., to prevent the roof from delaminating, etc., but there are generally large gaps between the several woods acting as backing materials, so that the force on various parts of the bracket is not uniform, and it cannot provide a good supporting effect on the coal seam. In this device, a number of first fixings can be placed on the top beam and the column legs in advance, and moved between the backing materials, and then the first threaded rods on both sides are rotated to allow the first outer cylinder to drive the pressure plate to fit tightly against the coal seam on one side, and then the distance between the first limit block and the second limit block is adjusted through the cooperation of the second outer cylinder and the second threaded rod, and they are respectively inserted into the inner side of the first fixing and the pressure plate to provide a supporting effect. This structural design enables the unfilled parts between the backing materials to be effectively filled, so that the column legs and the top beam surfaces are evenly stressed.

[0019] As a further solution of the present invention, the inner rod surface is fixedly connected with a connecting plate, the outer rod surface is slidably connected with a ring part, the connecting plate and the ring part are fixedly connected, and the outer rod surface located inside the ring part is fixedly connected with a scale bar.

[0020] Through the above technical scheme, the currently commonly used arch supports are mostly compression supports. When the coal seam is under pressure, the top beam is deformed by force, thereby avoiding direct damage to the support structure. However, the traditional top beam structure has weak compressive resistance. When the top beam is slightly deformed, it is difficult for workers to detect the coal seam pressure. This structure adds an outer rod and an inner rod between the top beam and the column leg, and a spring is set between the two. Therefore, when the top beam is under pressure, the spring will also be compressed and provide a certain compression resistance effect, and when the inner rod moves, the ring will also slide on the outer rod. The user can know the deformation of the top beam by regularly observing the position of the ring on the scale bar. This structural design can improve the compressive resistance of the top beam and monitor the deformation of the top beam at the same time, which is conducive to better ensuring the safety of workers.

[0021] Compared with the related art, the assembled support device provided by the present invention has the following beneficial effects:

[0022] 1. In the present invention, the currently commonly used arch supports are mostly compression supports. When the coal seam is under pressure, the top beam is deformed by force, thereby avoiding direct damage to the support structure. However, the traditional top beam structure has a weak compressive resistance. When the top beam is slightly deformed, it is difficult for workers to find the coal seam under pressure. In this structure, an outer rod and an inner rod are added between the top beam and the column legs, and a spring is arranged between the two. Therefore, when the top beam is under pressure, the spring will also be compressed and provide a certain compression resistance effect. When the inner rod moves, the annular member will also slide on the outer rod. The user can know the deformation of the top beam by regularly observing the position of the annular member on the scale bar. This structural design can improve the compressive resistance of the top beam and monitor the deformation of the top beam at the same time, which is conducive to better ensuring the safety of workers.

[0023] 2. In the present invention, since the arch support belongs to passive support, a backing material is generally arranged between the protective net and the bracket to achieve the top connection and prevent the top plate from delaminating. However, there are generally large gaps between the several woods acting as the backing materials, which makes the force on the bracket uneven and cannot play a good supporting effect on the coal seam. In this device, a number of first fixing members can be placed on the top beam and the column legs in advance, and moved between the backing materials, and then the first threaded rods on both sides are rotated to allow the first outer cylinder to drive the pressure plate to be close to the coal seam on one side, and then the distance between the first limit block and the second limit block is adjusted by the cooperation of the second outer cylinder and the second threaded rod, and they are respectively inserted into the inner side of the first fixing member and the pressure plate to play a supporting effect. This structural design enables the unfilled part between the backing materials to be effectively filled, so that the column legs and the top beam surface are evenly stressed;

[0024] 3. In the present invention, the foot locking anchor rod is a component that needs to be installed immediately after the top beam and the column leg are installed. This structure can prevent the arch foot from shrinking and the arch from hanging. When installing the structure, the second fixing member can be fixed to a suitable height on the base by the second fixing bolt. Since the guide member and the column leg in the structure maintain a specified angle, it is more convenient and accurate for workers to drill holes, and it is also easier to fix the foot locking anchor rod;

[0025] 4. In the present invention, in certain situations, due to roof collapse or underground coal mine operations, the support structure may topple or fall apart. At this time, if there are people below, the support components may easily hit the workers' heads directly, causing more serious accidents. The device has several sockets on the column legs and the top beams. After the support device is installed, the user fixes the safety hook in the socket at the appropriate position and hooks the chain with the safety hook. The fixed anchor rods at the ends of the chain need to be fixed in the coal seams on both sides or the top. In this way, when the structural components fall apart or tilt due to an accident, the chain has a dragging effect, so it can be prevented from directly hitting the people or equipment below, thereby protecting the safety of personnel and facilities.

[0039] A column leg 1, a top beam 2, a pressure-bearing component 4 and a supporting component 7, wherein two column legs 1 are provided and are respectively located on the left and right sides of the top beam 2, and a plurality of evenly distributed jacks 14 are provided on the surfaces of the column leg 1 and the top beam 2, and the pressure-bearing component 4 comprises a first fixing member 20, and both side walls of the first fixing member 20 are rotatably connected with a first threaded rod 27, and a first outer cylinder 26 is threadedly connected with the surface of the first threaded rod 27, and the first outer cylinder 26 is slidably connected with the first fixing member 20, and a pressure plate 21 is fixedly connected to the end of the first outer cylinder 26, and a second limiting block 24 is inserted on the surface of the pressure plate 21, and a first limiting block 23 is inserted on the surface of the first fixing member 20 located on one side of the pressure plate 21, and a second outer cylinder 29 is rotatably connected to the surface of the first limiting block 23, and a second outer cylinder 29 is rotatably connected to the surface of the second limiting block 24, and a second threaded rod 28 is fixedly connected to the surface of the second limiting block 24, and the second outer cylinder 29 is threadedly connected with the second threaded rod 28;

[0040] Ear plates are fixedly connected to the surfaces of the column legs 1 and the top beam 2. The support assembly 7 includes an outer rod 11, which is fixedly connected to the inner rod 10 through a spring. The inner rod 10 and the outer rod 11 are slidably connected. First bolts 17 are inserted at both ends of the outer rod 11 and the inner rod 10. The two first bolts 17 are respectively inserted into the ear plates on the top beam 2 and the column legs 1, and nuts are threadedly connected to the ends of the first bolts 17.

[0041] like Figure 1-9 As shown, the tops of the two column legs 1 are respectively located on the inner sides of the two ends of the top beam 2, and connecting parts 3 are provided on the upper and lower sides of the end of the top beam 2. The two connecting parts 3 distributed up and down are fixedly connected by a second bolt 18 and a fixing nut.

[0042] The top of the column leg 1 is arc-shaped and fits with the end of the top beam 2, and then the ends of the two structures are fixed together by the connecting piece 3, the second bolt 18 and the fixing nut.

[0043] like Figure 1-9 As shown, auxiliary components 5 are provided on one side of the top beam 2 and the column leg 1. The auxiliary components 5 include a safety hook 32. The safety hook 32 is arranged inside the insertion hole 14 on one side of the top beam 2 and the column leg 1. A chain 12 is arranged on the inner side of the safety hook 32. The end of the chain 12 is fixedly connected with a fixed anchor rod 19.

[0044] In some cases, due to roof collapse or underground coal mine operations, the support structure may topple or fall apart. If there are people below, the support components may easily hit the workers' heads directly, causing more serious accidents. The device has several sockets 14 on the column legs 1 and the top beams 2. After the support device is installed, the user fixes the safety hook 32 in the socket 14 at the appropriate position, and uses the safety hook 32 to hook the chain 12. The fixed anchor rod 19 at the end of the chain 12 needs to be fixed in the coal seam on both sides or the top. In this way, when the structural components fall apart or tilt due to an accident, the chain 12 has a dragging effect, so it can be prevented from directly hitting the people or equipment below, thereby protecting the safety of personnel and facilities.

[0045] like Figure 1-9 As shown, the bottoms of the two column legs 1 are fixedly connected to a base 8, a limiting assembly 6 is arranged on the upper side of the base 8, the limiting assembly 6 includes a second fixing member 22, the second fixing member 22 is arranged on the outer side of the column leg 1, the left and right side walls of the second fixing member 22 are fixedly connected to a guide member 15, the guide member 15 is arranged at an angle and a locking foot anchor rod 9 is arranged on the inner side of the guide member 15.

[0046] The locking foot anchor rod 9 is a component that needs to be installed immediately after the top beam 2 and the column leg 1 are installed. This structure can prevent the arch foot from shrinking and the arch from hanging. When installing the structure, the second fixing member 22 can be fixed to the base 8 at a suitable height using the second fixing bolt 30. Since the guide member 15 and the column leg 1 in the structure maintain a specified angle, it is more convenient and accurate for workers to drill holes, and it is also easier to fix the locking foot anchor rod 9.

[0047] like Figure 1-9 As shown, a second fixing bolt 30 is inserted into the surface of the second fixing member 22, and the second fixing bolt 30 is inserted into the socket 14 on one side of the surface of the column leg 1 and a second limiting nut is threadedly connected to its end. An opening 31 is provided on the surface of one side of the guide member 15, and the locking foot anchor rod 9 and the guide member 15 are welded.

[0048] After the rod body of the locking foot anchor rod 9 is fixed inside the coal seam, the locking foot anchor rod 9 and the guide member 15 can be fixed together through the opening 31, and the fixation is convenient and firm.

[0049] like Figure 1-9 As shown, a first fixing bolt 25 is inserted into the surface of the first fixing member 20 , and the first fixing bolt 25 is inserted into the insertion hole 14 on one side of the surface of the column leg 1 and a first limiting nut is threadedly connected to the end thereof.

[0050] Since the arch support is a passive support, a backing material is generally set between the protective net and the bracket to achieve the top connection and prevent the roof from delaminating. However, there are generally large gaps between the several woods acting as the backing materials, which makes the force on the bracket uneven and cannot provide a good support for the coal seam. In this device, a number of first fixing members 20 can be placed on the top beam 2 and the column leg 1 in advance and moved between the backing materials. Then, the first threaded rods 27 on both sides are rotated to allow the first outer cylinder 26 to drive the pressure plate 21 to fit tightly against the coal seam on one side. Then, the distance between the first limit block 23 and the second limit block 24 is adjusted through the cooperation of the second outer cylinder 29 and the second threaded rod 28, and they are respectively inserted into the inner sides of the first fixing member 20 and the pressure plate 21 to provide a support effect. This structural design enables the unfilled parts between the backing materials to be effectively filled, so that the force on the surface of the column leg 1 and the top beam 2 is uniform.

[0051] like Figure 1-9 As shown, a connecting plate is fixedly connected to the surface of the inner rod 10, a ring member 13 is slidably connected to the surface of the outer rod 11, the connecting plate and the ring member 13 are fixedly connected, and a scale bar 16 is fixedly connected to the surface of the outer rod 11 located inside the ring member 13.

[0052] At present, most commonly used arch supports are compression supports. When the coal seam is under pressure, the top beam 2 is deformed by force, thereby avoiding direct damage to the support structure. However, the traditional top beam 2 structure has weak compressive resistance. When the top beam 2 is slightly deformed, it is difficult for workers to detect the coal seam pressure. This structure adds an outer rod 11 and an inner rod 10 between the top beam 2 and the column leg 1, and a spring is set between the two. Therefore, when the top beam 2 is under pressure, the spring will also be compressed and provide a certain compression resistance effect, and when the inner rod 10 moves, the ring 13 will also slide on the outer rod 11. The user can know the deformation of the top beam 2 by regularly observing the position of the ring 13 on the scale bar 16. This structural design can improve the compressive resistance of the top beam 2 and monitor the deformation of the top beam 2 at the same time, which is conducive to better ensuring the safety of workers.

[0053] The working principle of an assembled support device provided by the present invention is as follows:

[0054] Step 1: Currently, most commonly used arch supports are compression supports. When the coal seam is under pressure, the top beam 2 is deformed by force, thereby avoiding direct damage to the support structure. However, the traditional top beam 2 structure has weak compressive resistance. When the top beam 2 is slightly deformed, it is difficult for workers to find the coal seam under pressure. This structure adds an outer rod 11 and an inner rod 10 between the top beam 2 and the column leg 1. A spring is set between the two. Therefore, when the top beam 2 is under pressure, the spring will also be compressed and provide a certain compression resistance effect. When the inner rod 10 moves, the ring 13 will also slide on the outer rod 11. The user can observe the position of the ring 13 on the scale bar 16 regularly to know the deformation of the top beam 2. This structural design can improve the compressive resistance of the top beam 2 and monitor the deformation of the top beam 2 at the same time, which is conducive to better ensuring the safety of workers.

[0055] The second step: Since the arch support belongs to passive support, a backing material is generally set between the protective net and the bracket to achieve the top connection and prevent the top plate from delaminating. However, there are generally large gaps between the several woods acting as the backing materials, which makes the force on the bracket uneven and cannot provide a good support effect for the coal seam. In this device, a number of first fixing members 20 can be placed on the top beam 2 and the column leg 1 in advance, and moved between the backing materials, and then the first threaded rods 27 on both sides are rotated to allow the first outer cylinder 26 to drive the pressure plate 21 to be close to the coal seam on one side, and then the distance between the first limit block 23 and the second limit block 24 is adjusted by the cooperation of the second outer cylinder 29 and the second threaded rod 28, and they are respectively inserted into the inner sides of the first fixing member 20 and the pressure plate 21 to provide a support effect. This structural design enables the unfilled part between the backing materials to be effectively filled, so that the force on the surface of the column leg 1 and the top beam 2 is uniform;

[0056] Step 3: The foot locking anchor rod 9 is a component that needs to be installed immediately after the top beam 2 and the column leg 1 are installed. This structure can prevent the arch foot from shrinking and the arch from hanging. When installing this structure, the second fixing member 22 can be fixed to the base 8 at a suitable height using the second fixing bolt 30. Since the guide member 15 and the column leg 1 in the structure maintain a specified angle, it is more convenient and accurate for workers to drill holes, and it is also easier to fix the foot locking anchor rod 9;

[0057] Step 4: In some cases, due to roof collapse or underground coal mine operations, the support structure may topple or fall apart. If there are people below, the support components may easily hit the workers' heads directly, causing more serious accidents. The device has several sockets 14 on the column legs 1 and the top beams 2. After the support device is installed, the user fixes the safety hook 32 in the socket 14 at the appropriate position, and uses the safety hook 32 to hook the chain 12. The fixed anchor rod 19 at the end of the chain 12 needs to be fixed in the coal seam on both sides or the top. In this way, when the structural components fall apart or tilt due to an accident, the chain 12 has a dragging effect, so it can be prevented from directly hitting the people or equipment below, thereby protecting the safety of personnel and facilities.
