Description

Technical Field

[0001] The present application relates to the technical field of hydraulic supports, and in particular to a single-row hydraulic support. Background Art

[0002] The return air lane is a specific lane in a coal mine, usually designed as a long and narrow passage, and its spatial structure allows the air flow to pass smoothly. Structurally, the return air lane needs to be reinforced to a certain extent according to the specific conditions of the mine to cope with various challenges of the underground environment.

[0003] In order to reinforce the return airway, an advance hydraulic support is usually installed in the return airway to support and protect it. However, for some coal mines, the roof conditions of the return airway are relatively fragmented. In the matching of working face equipment, there is often some space left on the side of the return airway under the transition frame at the end of the return airway. Since the advance hydraulic support cannot fully support this position, roof falls and wall spalling often occur, leaving the mine with greater safety issues.

[0004] To address this problem, many coal mines currently use traditional single-body support methods. However, due to the limitations of underground working conditions, the installation of single-body support often requires a lot of manpower and material resources, and the protection effect is not ideal.

DETAILED DESCRIPTION

[0034] In order to better explain the present application and facilitate understanding, the present application is described in detail below in conjunction with the accompanying drawings through specific implementation methods. The directional terms such as "upper", "lower", "inner", "outer", "front" and "back" mentioned in this article are used in the same way as in the examples in the examples in the examples in the examples. Figure 1 The orientation of is used as a reference. The position of the top beam 3 relative to the base 1 is defined as "up"; the position of the column 2 relative to the base 1 is defined as "inside"; the position of the front beam 4 relative to the shield beam 5 is defined as "front".

[0035] As mentioned above, the return air lane in the coal mine is an important part of the mine ventilation system, with a unique structure and function. The return air lane is usually narrow and long, complex in structure, and difficult to maintain. Because it is located deep underground and is affected by natural factors such as geological changes and groundwater erosion for a long time, it needs to be supported and reinforced to ensure its structural integrity and smooth ventilation.

[0036] The advanced hydraulic support is a support structure set up in the return air lane and controlled and operated by a hydraulic system. It uses the hydraulic principle and provides power through a hydraulic pump station to make the top beam of the support closely contact with the roof of the lane, thereby supporting and protecting the lane. During the coal mining process, as the working face advances, the roof of the return air lane may be affected by the mine pressure and sink or fall. At this time, the advanced hydraulic support can play its supporting and protective role to ensure the stability and safety of the lane.

[0037] However, for some coal mines, the roof conditions of the return air lane are relatively fragmented. In the matching of working face equipment, it is often found that there is some space left on the side of the return air lane under the transition frame at the end, such as Figure 8 As shown in the space 14 that needs support, since the advanced hydraulic support cannot fully support this location, roof falls and spalling often occur. Roof falls refer to the phenomenon that during mining, due to the activity of mine pressure, the roof rock layer undergoes deformation and damage to varying degrees, leading to rock fracture and collapse. Roof falls may occur when the roof is improperly protected, the support quality is poor, or the mine pressure continues to increase and exceeds the elastic deformation limit of the rock; spalling refers to the phenomenon that due to the suspension in the roof rock layer of the goaf, the pressure is transferred to the coal wall, and under the action of the additional load, part of the coal is crushed and squeezed into the goaf. The supporting pressure in front of the working face is the main reason for the spalling of the coal wall.

[0038] To address this problem, many coal mines currently use traditional single-body support methods. However, due to the limitations of underground working conditions, the installation of single-body support often requires a lot of manpower and material resources, and the protection effect is not ideal.

[0039] In order to solve at least one of the technical problems existing in the prior art or related technology, the present application provides a single-row hydraulic support, including: a base, a column, a top beam, a side first-level rock baffle plate, a side first-level jack, a side second-level rock baffle plate and a side second-level jack, wherein the column is arranged between the base and the top beam, and the columns are arranged in a single row from the front end direction of the top beam to the rear end direction of the top beam; a side first-level rock baffle plate and a side second-level rock baffle plate are provided on the side of the top beam close to the tunnel wall; one side of the side first-level rock baffle plate is hinged to the top beam, and the other side is hinged to the side second-level rock baffle plate; the side first-level jack is arranged on the top beam, and the telescopic end of the side first-level jack is hinged to the side first-level rock baffle plate, and the side first-level jack is used to adjust the angle of the side first-level rock baffle plate and play a supporting role; the side second-level jack is arranged on the side first-level rock baffle plate, and the telescopic end of the side second-level jack is hinged to the side second-level rock baffle plate, and the side second-level jack is used to adjust the angle of the side second-level rock baffle plate and play a supporting role. The main body of the single-row hydraulic support is composed of a single base, a single shield beam, and a single top beam. The columns are arranged in a single row, making the support narrower as a whole, and can well adapt to the small space under the transition frame at the end of the return air channel and on the side. Compared with the traditional single-row support, the single-row hydraulic support has a simple structure, low cost, and convenient use, which solves the problems of high labor intensity and long time consumption; compared with the traditional double-row end-end support, the single-row hydraulic support has only a single row and the support is narrower as a whole, which solves the problem that the traditional double-row end-end support cannot support when the space under the transition frame at the end is small. The top beam and cover beam of the single-row hydraulic support are provided with primary and secondary side flaps on the side away from the tunnel wall, which can be selectively installed according to the actual support space during use, and have the advantage of a large support range; a primary side rock baffle, a secondary side rock baffle and a base rock baffle are provided on the side close to the tunnel wall to prevent gangue from pouring into the working face. At the same time, the distance between the side and base rock baffles and the tunnel wall is adjustable, and they can also provide side protection to prevent rock from spalling.

[0040] The following describes a single-row hydraulic support according to some embodiments provided by the present application with reference to the accompanying drawings.

[0041] See also Figures 1 to 8A single-row hydraulic support provided by the first embodiment of the present application includes: a base 1, a column 2, a top beam 3, a side first-level rock baffle plate 8, a side first-level jack 801, a side second-level rock baffle plate 9 and a side second-level jack 901, wherein the column 2 is arranged between the base 1 and the top beam 3, and the column 2 is arranged in a single row from the front end direction of the top beam 3 to the rear end direction of the top beam 3; a side first-level rock baffle plate 8 and a side second-level rock baffle plate 9 are provided on one side of the top beam 3 close to the tunnel wall; one side of the side first-level rock baffle plate 8 is hinged to the top beam 3 , and the other side is hinged to the side secondary rock baffle plate 9; the side first-level jack 801 is arranged on the top beam 3, and the telescopic end of the side first-level jack 801 is hinged to the side first-level rock baffle plate 8, and the side first-level jack 801 is used to adjust the angle of the side first-level rock baffle plate 8 and play a supporting role; the side second-level jack 901 is arranged on the side first-level rock baffle plate 8, and the telescopic end of the side second-level jack 901 is hinged to the side second-level rock baffle plate 9, and the side second-level jack 901 is used to adjust the angle of the side second-level rock baffle plate 9 and play a supporting role.

[0042] The base 1 is in direct contact with the ground of the tunnel, providing a solid foundation for the bracket, ensuring that the bracket will not shake or tilt due to external force during use, which has high requirements on the rigidity and strength of the base 1; the top beam 3 is in direct contact with the roof of the tunnel, and is used to bear the load of rocks and coal from the roof to ensure that the roof remains stable; the column 2 adopts a hydraulic telescopic arm structure to control the contact between the top beam 3 and the roof of the tunnel. The column 2 is arranged in a single row, so that the bracket is narrow as a whole, which can well adapt to the small space on the lower side of the transition frame at the end of the return air tunnel.

[0043] like Figure 2 As shown, the first-level side rock baffle 8 and the second-level side rock baffle 9 are used to protect the tunnel wall. The design of the two-level rock baffle allows a larger adjustment angle of the rock baffle. Compared with a single rock baffle, the two-level rock baffle provides a more reliable safety guarantee and can better adapt to the actual situation of the tunnel working surface. This helps to reduce the downtime caused by falling gangue, thereby improving work efficiency.

[0044] The first-level jack 801 and the second-level jack 901 are key lifting and supporting components. The telescopic ends of the jacks can be extended and retracted by hydraulic principle, so as to adjust the angles of the first-level slag baffle 8 and the second-level slag baffle 9. The lifting function of the jacks can make the first-level slag baffle 8 and the second-level slag baffle 9 adapt to different roadway conditions and provide effective support.

[0045] In an illustrative embodiment, Figure 1As shown, the single-row hydraulic support also includes: a front beam 4 and a front beam jack 401. The front beam 4 is arranged at the front end of the top beam 3, and the front beam 4 is hinged to the top beam 3; the front beam jack 401 is arranged on the top beam 3, and the telescopic end of the front beam jack 401 is hinged to the front beam 4. The front beam jack 401 is used to adjust the angle of the front beam 4 and play a supporting role.

[0046] The front beam 4 is used to increase the supporting area. The hinged design between the front beam 4 and the top beam 3 enables the front beam 4 to be adjusted accordingly according to the ups and downs and changes of the tunnel roof. This adaptability ensures that the bracket can always maintain close contact with the tunnel roof, thereby effectively dispersing and bearing the pressure from the tunnel roof.

[0047] The function of the front beam jack 401 is the same as that of the side primary jack 801 and the side secondary jack 901, and will not be described in detail.

[0048] In an illustrative embodiment, Figure 3 As shown, the front beam 4 also includes: a telescopic beam 402 and a telescopic beam jack 403, the telescopic beam 402 is slidably connected to the front beam 4; the telescopic beam jack 403 is arranged on the front beam 4, the telescopic end of the telescopic beam jack 403 is hinged to the telescopic beam 402, and the telescopic beam jack 403 is used to adjust the telescopic length of the telescopic beam 402 and play a supporting role.

[0049] The telescopic beam 402 is arranged at the front end of the front beam 4 to further increase the support area. By controlling the extension of the telescopic beam 402 through the telescopic beam jack 403, a safe support and maintenance space can be formed in the goaf to prevent the collapse of gangue from threatening the working face.

[0050] In an illustrative embodiment, Figure 1 As shown, the single-row hydraulic support also includes: a shielding beam 5, a front connecting rod 6 and a rear connecting rod 7. The shielding beam 5 is arranged at the rear end of the top beam 3, and the shielding beam 5 is hinged to the top beam 3; the shielding beam 5 is connected to the base 1 through the front connecting rod 6 and the rear connecting rod 7.

[0051] The shield beam 5 not only bears the weight load of the gangue falling from the goaf, but also bears the lateral load imposed on the support by the roof, which can enhance the torsion resistance of the support and enable the support to remain stable when subjected to external forces. The shield beam 5 can transfer part of the pressure borne by the top beam 3 to the base 1 through the front connecting rod 6 and the rear connecting rod 7, so as to achieve reasonable distribution and transmission of pressure. The design of the hinged connection between the shield beam 5 and the top beam 3 can be adjusted accordingly according to the ups and downs and changes of the tunnel roof to adapt to different mining conditions.

[0052] In an illustrative embodiment, Figure 4As shown, the shield beam 5 further includes: a shield beam primary side flap 501, a shield beam secondary side flap 502, a shield beam primary jack 503 and a shield beam secondary jack 504, wherein the shield beam primary side flap 501 and the shield beam secondary side flap 502 are arranged on the side of the shield beam 5 away from the tunnel wall; one side of the shield beam primary side flap 501 is hinged to the shield beam 5, and the other side is hinged to the shield beam secondary side flap 502; the shield beam primary jack 503 is arranged on the shield beam 5, The telescopic end of the first-level jack 503 of the shielding beam is hinged to the first-level side flap plate 501 of the shielding beam, and the first-level jack 503 of the shielding beam is used to adjust the angle of the first-level side flap plate 501 of the shielding beam and play a supporting role; the second-level jack 504 of the shielding beam is arranged on the first-level side flap plate 501 of the shielding beam, and the telescopic end of the second-level jack 504 of the shielding beam is hinged to the second-level side flap plate 502 of the shielding beam, and the second-level jack 504 of the shielding beam is used to adjust the angle of the second-level side flap plate 502 of the shielding beam and play a supporting role.

[0053] The first-level side flap 501 and the second-level side flap 502 of the protective beam are used to further increase the support area. The first-level side flap 501 and the second-level side flap 502 of the protective beam are adjusted to be on the same plane with the protective beam 5 through the first-level jack 503 and the second-level jack 504 of the protective beam, so as to form a safe support and maintenance space in the goaf to prevent the collapse of gangue from posing a threat to the working face.

[0054] The functions of the shield beam primary jack 503 and the shield beam secondary jack 504 are the same as those of the side primary jack 801 and the side secondary jack 901, and will not be described in detail.

[0055] In an illustrative embodiment, Figure 4 As shown, the shielding beam 5 includes: a shielding beam main box 507 and two shielding beam side boxes 508, wherein two shielding beam main ribs 505 constitute the shielding beam main box 507; the shielding beam outer ribs 506 and the shielding beam main ribs 505 constitute the shielding beam side boxes 508 on both sides of the shielding beam main box 507; the front connecting rod 6 and the rear connecting rod 7 are arranged in the shielding beam main box 507.

[0056] The function of the shield beam side box 508 is to increase the rigidity and width of the shield beam 5, so that the width of the shield beam 5 is greater than the width of the top beam 3. During transportation and use of the single-row hydraulic support, when the top beam primary side flap 301, the top beam secondary side flap 302 and the shield beam primary side flap 501, the shield beam secondary side flap 502 are retracted at the same time, there is a misalignment between them, that is, the top beam primary side flap 301, the top beam secondary side flap 302 are on the inside, and the shield beam primary side flap 501, the shield beam secondary side flap 502 are on the outside to avoid interference with each other.

[0057] In an illustrative embodiment, Figure 3As shown, the top beam 3 also includes: a top beam first-level side flap 301, a top beam second-level side flap 302, a top beam first-level jack 303 and a top beam second-level jack 304, wherein the top beam first-level side flap 301 and the top beam second-level side flap 302 are arranged on the side of the top beam 3 away from the tunnel wall; one side of the top beam first-level side flap 301 is hinged to the top beam 3, and the other side is hinged to the top beam second-level side flap 302; the top beam first-level jack 303 is arranged on the top beam 3, and the top beam The telescopic end of the first-level jack 303 is hinged to the first-level side flap 301 of the top beam, and the first-level jack 303 of the top beam is used to adjust the angle of the first-level side flap 301 of the top beam and play a supporting role; the second-level jack 304 of the top beam is arranged on the first-level side flap 301 of the top beam, and the telescopic end of the second-level jack 304 of the top beam is hinged to the second-level side flap 302 of the top beam, and the second-level jack 304 of the top beam is used to adjust the angle of the second-level side flap 302 of the top beam and play a supporting role.

The first-level side flap 301 and the second-level side flap 302 of the top beam are adjusted to be on the same plane with the top beam 3 through the first-level jack 303 and the second-level jack 304 of the top beam, so as to form a safe support and maintenance space in the goaf to prevent the collapse of gangue from posing a threat to the working face.

[0059] The functions of the top beam primary jack 303 and the top beam secondary jack 304 are the same as those of the side primary jack 801 and the side secondary jack 901, and will not be described in detail.

[0065] The design of the frame adjustment jack 13 being hinged to the base 1 allows the frame adjustment jack to rotate horizontally, so that the adjustment angle can be freely selected in a small space. When the bracket is deflected, the bracket can be aligned through the action of the frame adjustment jack 13.

[0066] Furthermore, a bottom adjustment jack 12 can be provided on the base 1, and the bottom adjustment jack 12 and the frame adjustment jack 13 are respectively provided at the front and rear ends of the base 1, and the telescopic end of the bottom adjustment jack 12 is located on the side close to the tunnel wall. This design allows adjustment in two directions, making it more convenient to align the bracket.

[0067] Furthermore, a push jack 11 can be arranged at the front end of the base 1, and the push jack 11 is used to drive the single-row hydraulic support to move forward.
