The inventor of the application researches and discovers that the existing supporting equipment in the coal mining process has the defect that the top coal cannot be recovered, so that a large amount of coal mine resources are lost into a goaf, and waste is huge.
In coal mining operations, the main functions of the support apparatus are to support the roof, shield the conveyor heads and conveyor tails below, and set the roof behind the support apparatus down (i.e., break and then collapse at the back of the roof beam structure of the support apparatus). However, when the support device is used in a thick coal seam roadway, coal rather than stones fall down above the top beam structure of the support device and are preferably recovered. In the existing supporting equipment, the rear part of the top beam structure is a gangue blocking tail beam, a coal discharging port for pushing coal out is not formed, a large-size chassis is arranged at the lower part of the supporting equipment, and a material conveying channel extending to the rear part of the supporting equipment cannot be provided for a conveyor, so that the defect that the pushing coal cannot be recovered exists.
The application provides a supporting equipment aims at solving the technical problem in the prior art.
The following describes the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems in detail with specific embodiments.
The embodiment of the application provides a supporting device, and a structural schematic diagram of the supporting device is shown in fig. 1, including: bracket 100 and back rail assembly 200.
The stand 100 includes: a header structure 110 and support columns 120; one end of the support column 120 is connected with the top beam structure 110, and the other end of the support column 120 is used for directly abutting against the ground of a roadway.
The back rail assembly 200 includes: a coal baffle 210 and a telescoping column 220.
One end of the telescopic column 220 is connected with the tail of the top beam structure 110, and the other end of the telescopic column 220 faces the ground of the roadway.
The coal baffle 210 is connected to the telescopic column 220, and the coal baffle 210 can be lifted and lowered along with the telescopic column 220.
In the present embodiment, the bracket 100 adopts the structure of the top beam structure 110 and the support column 120, which not only can maintain the support of the top plate, but also has the function of cutting off the top plate. The other end of each support column 120 is used for directly abutting against the ground of a roadway, a large-size chassis structure is abandoned, a space is obtained between the support columns 120, and a material conveying channel extending to the rear of supporting equipment can be provided for a conveyor.
The back tail boom assembly 200 is connected to the telescopic column 220 at the tail of the top beam structure 110, and can block the waste burst by being matched with the coal baffle 210. The telescopic column 220 can lift the coal baffle 210 timely to form a coal discharging port, so that the top coal falling from the upper part of the top plate can slide out from the lower part of the coal baffle 210, thereby recovering the top coal, reducing waste and improving the exploitation rate of coal mine resources.
Alternate lifting may be used during operation so that as a portion of the telescoping columns 220 lift the coal caving, the remaining telescoping columns 220 continue to provide support for the tail portion of the header structure 110.
Alternatively, the telescoping column 220 may be a jack.
In some possible embodiments, the telescoping post 220 is parallel to the support post 120. The telescoping post 220 of the back rail assembly 200 is parallel to the support post 120 of the bracket 100 such that the telescoping post 220 can help the support post 120 of the bracket 100 provide support to the header structure 110, particularly to the tail of the header structure 110.
In some possible embodiments, the coal baffle 210 is located on a side of the telescoping post 220 that is remote from the support post 120. I.e., the coal deflector 210 is closer to the coal or gangue than the telescoping column 220.
In some possible embodiments, the telescoping post 220 is one of the support posts 120. The structure and power of the existing support column 120 can be adopted, and the structure of the telescopic column 220 is not required to be designed, manufactured and maintained additionally, so that the cost is reduced.
In some possible embodiments, the back rail assembly 200 further includes a base 230.
One of the moving part and the fixed part of the telescopic column 220 is connected to the header structure 110, and the other of the moving part and the fixed part of the telescopic column 220 is connected to the base 230.
In this embodiment, the base 230 is configured to contact the roadway floor when the telescoping mast 220 is lowered, which enhances the stability of the telescoping mast 220 and support for the roof rail structure 110, such as on soft roadway floors, and the base 230 prevents sagging. When the telescoping column 220 is lifted, the base 230 may cooperate with the coal deflector 210 to define an upper boundary of the coal chute.
Alternatively, the coal baffle 210 may be directly and fixedly connected to the base 230, and the coal baffle 210 is indirectly connected to the telescopic column 220 through the connection between the base 230 and the telescopic column 220.
To enhance the stability of the telescoping pole 220 during lifting or lowering, the present application provides one possible implementation of the support apparatus as follows:
as shown in fig. 2-4, the back rail assembly 200 of the present embodiment also includes a guide post 240.
The guide post 240 includes a first sub-post 241 and a second sub-post 242. The first sub-column 241 is parallel to the axis of the second sub-column 242, and the first sub-column 241 is slidably connected to the second sub-column 242 along the axial direction.
The end of the first sub-column 241 remote from the second sub-column 242 is connected to the header structure 110.
An end of the second sub-column 242 remote from the first sub-column 241 is connected to the base 230.
The coal baffle 210 is connected to a side of the second sub-column 242 remote from the support column 120.
In this embodiment, the guide post 240 of the back rail assembly 200 includes a first sub-post 241 and a second sub-post 242 that are slidably connected to provide directional restriction for the telescoping motion, which is beneficial for improving stability of the telescoping motion. Alternatively, the first sub-column 241 and the second sub-column 242 of the guide column 240 may be connected in a sleeved sliding manner, or may be connected in a sliding manner by a slider and a sliding rail. Specifically, the telescopic column 220 can drive the base 230 to lift, so as to indirectly drive the second sub-column 242 and the first sub-column 241 to slide relatively.
The coal baffle 210 is connected to the side of the second sub-column 242 far away from the support column 120, so that the stability of the coal baffle 210 during follow-up can be enhanced, the supporting point of the coal baffle 210 is increased, and the strength of the coal baffle 210 for blocking gangue is improved. The connection between the coal baffle 210 and the second sub-column 242 may be a fixed connection manner, so as to enhance the connection stability; and the detachable connection mode can be adopted, so that the transportation and the later operation and maintenance are convenient.
In some possible embodiments, as shown in fig. 2, the guide posts 240 and the telescoping posts 220 are arranged side-by-side and spaced apart along the width of the header structure 110.
In this embodiment, the guide posts 240 and the telescopic posts 220 are arranged side by side and at intervals, which is beneficial to stabilizing the movement direction of the whole back rail assembly 200 during telescopic operation.
Optionally, the number of guide posts 240 is greater than the number of telescoping posts 220. As shown in fig. 3, a telescoping post 220 is disposed between each two adjacent guide posts 240.
Optionally, the number of telescoping posts 220 is greater than the number of guide posts 240. As shown in fig. 4, a guide post 240 is disposed between each adjacent telescopic post 220.
It will be appreciated that the two approaches described above may be used in combination.
In some possible embodiments, at least part of the first sub-column 241 is a hollow sleeve structure, and the second sub-column 242 extends into the first sub-column 241 based on a slidable manner.
The coal baffle 210 is connected with the part of the second sub-column 242 which is always positioned outside the first sub-column 241.
In this embodiment, the first sub-column 241 and the second sub-column 242 adopt a sleeved sliding connection mode, at this time, the axes of the first sub-column 241 and the second sub-column 242 may be coincident, so that coaxial relative movement is easier to be realized, the stress during sliding is more balanced, and the stability is high. The coal baffle 210 is always connected with the portion of the second sub-column 242 located outside the first sub-column 241, i.e. can be lifted along with the sliding of the second sub-column 242. The connection between the coal baffle 210 and the second sub-column 242 may be a fixed connection manner, so as to enhance the connection stability; and the detachable connection mode can be adopted, so that the transportation and the later operation and maintenance are convenient.
Optionally, the coal baffle 210 may be partially slidably coupled to the outer wall of the first sub-column 241 to enhance the coupling relationship of the coal baffle 210 to the guide column 240.
In other possible embodiments, the second sub-column 242 is a sleeve structure. The first sub-column 241 extends into the second sub-column 242 based on a slidable manner.
The coal baffle 210 is connected to the second sub-column 242.
This embodiment is identical in principle to the previous embodiment, except that: the second sub-column 242 is a sleeve structure, and the coal baffle 210 is connected to the second sub-column 242. When the whole rear tail beam assembly 200 is contracted, the contact ratio between the first sub-column 241 and the second sub-column 242 is higher, whereas when the whole rear tail beam assembly 200 is expanded, the total length of the first sub-column 241 and the second sub-column 242 can be longer, i.e. the variable travel of the guide column 240 is larger.
The inventors of the present application contemplate that if the coal baffle 210 is optimized, a personalized coal discharge pattern may be achieved. To this end, the present application provides the following one possible implementation for the support device:
as shown in fig. 2, the coal baffle 210 in the embodiment of the present application includes a plurality of sub-baffles 210a, and any sub-baffle 210a is at least correspondingly connected to one telescopic column 220.
In this embodiment, the sub-barriers 210a at different positions may be controlled separately.
Specifically, one or a part of the telescopic columns 220 can be controlled to stretch and retract to drive the sub-baffle 210a connected with the telescopic column 220 which stretches and contracts to lift and retract, so that the coal discharging port is opened and closed. At the same time, the other telescopic columns 220 are maintained in a supported state with respect to the top beam structure 110, so that the sub-blind 210a connected to the telescopic columns 220 maintained in the supported state is maintained in a state of blocking the spoil flush. According to the operation requirement, the telescopic column 220 which stretches and contracts and the telescopic column 220 which keeps the supporting state can alternately work, namely, alternately stretch and contract or keep the supporting, so as to form coal discharging ports at different positions and realize the opening and closing of the coal discharging ports.
Alternatively, a certain distance may be provided between two adjacent sub-baffles 210a, so as to provide a required movement space for each sub-baffle 210a connected to the telescopic beam, so as to avoid mutual interference between two adjacent sub-baffles 210 a. Optionally, the distance is no greater than the average diameter of the coal or gangue to provide adequate barrier capability.
In some possible embodiments, the sub-baffle 210a extends toward the base 230 and is connected to the base 230.
In this embodiment, the sub-baffle 210a extends toward the base 230 and is connected to the base 230, so that the base 230 can be utilized to increase the area available for blocking the gangue, thereby improving the blocking capability of the gangue.
Alternatively, the form of a side of the base 230 remote from the support column 120 may be adapted to the sub-baffle 210 a. For example, a side of the base 230 remote from the support column 120 is a plane having the same flatness as a side of the sub-baffle 210a facing the refuse, or a curved surface having the same curvature.
The inventors contemplate that modifications to the header structure 110 may also provide a gently-turned bearing surface at the tail of the header structure 110. To this end, the present application provides the following one possible implementation for the support device:
as shown in fig. 1, the header structure 110 of the present embodiment includes a number of headers 111 and a number of connectors 112.
The top beams 111 are parallel to each other and extend to the rear of the support device.
The rear part of the top beam 111 has a bending part 111a, and the bending part 111a is bent from the axial direction of the top beam 110 to a direction parallel to the support column 120.
The bent portions 111a of the adjacent two roof beams 111 are connected by a connecting member 112.
One end of the telescopic column 220 is connected with one of the connecting member 112 and the end of the bent portion 111a, which is fixedly or detachably connected.
One end of the first sub-column 241 of the guide column 240, which is far from the second sub-column 242, is connected with the other one of the connecting piece 112 and the end of the bent portion 111a, which is fixedly or detachably connected.
In this embodiment, the top beam structure 110 includes a plurality of top beams 111 for jacking the top plate, and the bending portion 111a of the top beam 111 provides a gentle turning support for the top plate at the tail of the top beam structure 110, which is beneficial for the top plate to start to discharge coal or falling rocks at the back tail beam assembly 200, and on the other hand, can be more suitable for the angle of the telescopic column 220 or the guide column 240, so that the telescopic column 220 provides a more powerful support for the top beam structure 110.
The connection member 112 is connected to the bent portion 111a of the adjacent top beam 111, so that the strength of the top beam 111 at the bent portion 111a can be improved, and the connection member 112 provides a supporting point for the telescopic column 220 or the guide column 240. The connection between the connection member 112 and the bent portion 111a of the adjacent header 111 may be a fixed connection or a detachable connection.
It will be appreciated that the provision of bends in the telescoping post 220 and/or the guide post 240 may also be employed to achieve a gentle turn between the header structure 110 and the back rail assembly 200.
Optionally, the top beam structure 110 may further include a plurality of joists, where the joists are perpendicular to the axial direction of the top beam 111 and are connected to the plurality of top beams 111, and the top beam 111 and the joists may each be made of a rectangular square steel body, so that a strong rigidity is obtained, which is also beneficial to weight reduction.
The inventors of the present application contemplate that one end of the first sub-column 241 of the steering column 240 may need to be connected to the tail of the header structure 110. To this end, the present application provides the following one possible implementation for the support device:
one of the fixed connection and the detachable connection is between one end of the first sub-column 241 of the guide column 240 and the tail of the top beam structure 110.
In this embodiment, if a fixed connection, such as welding, is adopted between one end of the first sub-column 241 and the top beam structure 110, the connection between the first sub-column 241 and the top beam structure 110 can be provided with a stronger stability.
If a detachable connection, such as plugging, is adopted between one end of the first sub-column 241 and the top beam structure 110, the connection between the first sub-column 241 and the top beam structure 110 has detachability, so that the supporting device is convenient to transport in a detached form, the transportation difficulty and the transportation cost are reduced, and only the whole guide column 240 or the first sub-column 241 is replaced in the later operation and maintenance process, thereby being beneficial to reducing the operation and maintenance cost.
Optionally, one end of the telescopic column 220 is fixedly connected, detachably connected, and rotatably connected to the tail portion of the top beam structure 110, and the other end of the telescopic column 220 is rotatably connected to the base 230.
In this embodiment, if a fixed connection, such as welding, is adopted between one end of the telescopic column 220 and the top beam structure 110, the connection between the telescopic column 220 and the top beam structure 110 can be provided with a strong stability.
If a detachable connection, such as plugging, is adopted between one end of the telescopic column 220 and the top beam structure 110, the connection between the telescopic column 220 and the top beam structure 110 has detachability, so that the supporting device is convenient to transport in a detached form, the transportation difficulty and the transportation cost are reduced, and only the telescopic column 220 is replaced in the later operation and maintenance process, thereby being beneficial to reducing the operation and maintenance cost.
If a rotatable connection, such as a hinge, is adopted between one end of the telescopic column 220 and the top beam structure 110, a certain self-adjusting angle can be provided between the telescopic column 220 and the top beam structure 110, so as to automatically correct the difference between the actual installation angle and the design angle caused by factors such as uneven roadway floor.
The other end of the telescopic column 220 is rotatably connected with the base 230, for example, hinged, so that the base 230 has a certain capability of automatically adjusting an angle to adapt to uneven roadway ground, the contact area between the base 230 and the roadway ground is increased, and the supporting stability of the telescopic column 220 to the top beam structure 110 is further improved.
The inventors of the present application considered that a certain space needs to be provided between the support columns 120 to provide a transport path for the conveyor extending to the rear of the support apparatus. To this end, the present application provides the following one possible implementation for the support device:
the adjacent two support columns 120 in the width direction of the top beam structure 110 in the embodiment of the application have a specified distance, and the specified distance is not smaller than the width of the conveyor.
In this embodiment, the specified distance between the support columns 120 enables the provision of a transport path for the conveyor extending to the rear of the support apparatus.
Optionally, the central axis of the top beam structure 110 is not provided with the support column 120, and correspondingly, the other end of the support column 120 is not abutted to the central axis of the projection of the top beam structure 110 on the ground of the roadway, so that a corridor capable of placing a conveyor is left below the top beam structure 110. The conveyor may continue to extend below the back tail boom assembly 200 and may be as close as possible to the telescoping post 220, the coal deflector 210, and the base 230, i.e., as close as possible to the coal chute.
By applying the above embodiments provided by the application, at least the following beneficial effects can be achieved:
1. the bracket 100 adopts the structure of the top beam structure 110 and the support column 120, can maintain the support of the top plate, and has the function of cutting off the top plate. The other end of each support column 120 is used for directly abutting against the ground of a roadway, a large-size chassis structure is abandoned, a space is obtained between the support columns 120, and a material conveying channel extending to the rear of supporting equipment can be provided for a conveyor.
2. The back tail boom assembly 200 is connected to the telescopic column 220 at the tail of the top beam structure 110, and can block the waste burst by being matched with the coal baffle 210. The telescopic column 220 can lift the coal baffle 210 timely to form a coal discharging port, so that the top coal falling from the upper part of the top plate can slide out from the lower part of the coal baffle 210, thereby recovering the top coal, reducing waste and improving the exploitation rate of coal mine resources.
3. The telescoping post 220 of the back rail assembly 200 is parallel to the support post 120 of the bracket 100 such that the telescoping post 220 can help the support post 120 of the bracket 100 provide support to the header structure 110, particularly to the tail of the header structure 110.
4. The telescoping pole 220 is one type of support pole 120. The structure and power of the existing support column 120 can be adopted, and the structure of the telescopic column 220 is not required to be designed, manufactured and maintained additionally, so that the cost is reduced.
5. The back rail assembly 200 also includes a base 230. The base 230 is configured to contact the floor of the roadway when the telescoping mast 220 is lowered, which may enhance the stability of the telescoping mast 220 and support for the roof rail structure 110.
