top plate: the coal seam and rock stratum at the top of the roadway.

The inventor of the application researches and discovers that the existing supporting equipment in the coal mining process has the defect that top coal cannot be recovered, so that a large amount of coal mine resources are lost into a goaf, and the waste is huge.

In coal mining operations, the main functions of the support device are to support the roof, shield the underlying conveyor head and the end of the reversed conveyor, and to set the roof behind the support device down (i.e., break and then collapse behind the roof structure of the support device). However, when used in a thick seam roadway, coal rather than stones fall over the roof beam structure of the support equipment and should be recovered well. In the existing supporting equipment, the rear part of a top beam structure is provided with a gangue blocking tail beam, a coal discharge port for discharging top coal is not formed, and the lower part of the supporting equipment is provided with a large-size chassis which cannot provide a material conveying channel extending towards the rear part of the supporting equipment for a conveyor, so that the defect that the top coal cannot be recovered exists.

The application provides a support equipment aims at solving prior art technical problem as above.

The following describes the technical solutions of the present application and how to solve the above technical problems with specific embodiments.

The embodiment of the application provides a supporting device, and a schematic structural diagram of the supporting device is shown in fig. 1, and the supporting device comprises: a bracket 100 and a rear tail boom assembly 200.

The stent 100 includes: a header structure 110 and a support column 120; one end of the support pillar 120 is connected to the roof beam structure 110 and the other end of the support pillar 120 is adapted to directly abut the floor of the roadway.

The rear tail boom assembly 200 includes: a coal deflector 210 and a retractable post 220.

One end of the telescopic column 220 is connected with the tail of the roof beam structure 110, and the other end of the telescopic column 220 faces the ground of the roadway.

The coal deflector 210 is connected to the telescopic column 220, and the coal deflector 210 can be raised and lowered as the telescopic column 220 is extended and retracted.

In the present embodiment, the support 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 the 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 the supporting equipment can be provided for the conveyor.

The rear tail beam assembly 200 is connected to the telescopic pillar 220 at the rear of the top beam structure 110, and can block the rock gangues from gushing out by matching with the coal blocking plate 210. The retractable columns 220 can lift the coal baffle 210 in due time to form a coal discharge port, so that top coal falling from the top of the roof slides out from the lower part of the coal baffle 210, thereby recovering the top coal, reducing waste and improving the mining rate of coal mine resources.

In operation, the lifting mechanism may be used in an alternate manner, such that when a portion of the telescopic pillars 220 are lifted to release coal, the remaining telescopic pillars 220 can continue to provide support to the rear portion of the roof rail structure 110.

Alternatively, the telescoping column 220 may be a jack.

In some possible embodiments, the retractable posts 220 are parallel to the support posts 120. Telescoping post 220 of rear tail boom assembly 200 is parallel to support post 120 of rack 100 such that telescoping post 220 may help support post 120 of rack 100 provide support to top boom structure 110, and in particular support to the rear of top boom structure 110.

In some possible embodiments, the coal deflector 210 is located on a side of the telescoping column 220 that is distal from the support column 120. I.e., the coal shield 210 is closer to the coal or gangue than the telescoping post 220.

In some possible embodiments, the retractable post 220 is one of the support posts 120. Therefore, the structure and power of the existing support column 120 can be adopted, and the structure of the telescopic column 220 does not need to be additionally designed, manufactured and maintained, so that cost reduction is facilitated.

In some possible embodiments, the rear tail boom assembly 200 further includes a base 230.

One of the moving and fixed portions of the telescopic column 220 is connected to the header structure 110 and the other of the moving and fixed portions of the telescopic column 220 is connected to the base 230.

In this embodiment, the base 230 is used to contact the floor of the roadway when the retractable column 220 is lowered, so that the supporting stability of the retractable column 220 and the roof beam structure 110 can be enhanced, for example, the base 230 can prevent sinking on the floor of the roadway with soft texture. When the retractable columns 220 are raised, the base 230 may engage the coal deflector 210 to define the upper boundary of the coal discharge opening.

Alternatively, the coal deflector 210 may be fixedly connected to the base 230 directly, and the coal deflector 210 may be connected to the retractable column 220 indirectly through the connection between the base 230 and the retractable column 220.

To enhance the stability of the retractable column 220 during lifting or lowering, the present application provides one possible implementation manner for the supporting device:

as shown in fig. 2-4, the rear tail boom assembly 200 of the present embodiment further 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 connected with the second sub-column 242 in an axial sliding manner.

An 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 deflector 210 is connected to a side of the second sub-column 242 remote from the support column 120.

In this embodiment, the guiding column 240 of the rear tail boom assembly 200 includes a first sub-column 241 and a second sub-column 242 which are slidably connected to provide a direction limitation for the telescopic movement, which is beneficial to improving the stability of the telescopic movement. Optionally, the first sub-column 241 and the second sub-column 242 of the guiding column 240 may adopt a sliding connection manner of socket joint, or a sliding connection manner of a sliding block and a sliding rail matching. Specifically, the retractable column 220 can drive the base 230 to move up and down, thereby indirectly driving the second sub-column 242 to slide relative to the first sub-column 241.

The coal baffle 210 is connected to one side of the second sub-column 242, which is far away from the support column 120, so that the stability of the coal baffle 210 during follow-up can be enhanced, the support points of the coal baffle 210 are increased, and the strength of the coal baffle 210 for blocking gangue is improved. The coal baffle 210 and the second sub-column 242 can be fixedly connected to enhance the stability of the connection; also can adopt the mode of dismantling the connection, be convenient for transportation and later stage fortune dimension.

In some possible embodiments, as shown in fig. 2, the guide posts 240 and the retractable posts 220 are arranged side by side and spaced apart along the width direction of the header structure 110.

In this embodiment, the guiding posts 240 and the retractable posts 220 are arranged side by side and spaced apart, which is beneficial to make the moving direction of the whole rear tail beam assembly 200 more stable when being retracted.

Optionally, the number of guide posts 240 is greater than the number of telescoping posts 220. As shown in fig. 3, one retractable post 220 is disposed between every two adjacent guide posts 240.

Optionally, there are more retractable posts 220 than guide posts 240. As shown in fig. 4, a guide post 240 is disposed between every two adjacent retractable posts 220.

It will be appreciated that the two aforementioned approaches may be used in combination.

In some possible embodiments, at least a portion of the first sub-column 241 is a hollow sleeve structure, and the second sub-column 242 is inserted into the first sub-column 241 in a slidable manner.

The coal baffle 210 is connected with the portion of the second sub-column 242 which is always located 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 manner, and at this time, the axes of the first sub-column 241 and the second sub-column 242 may coincide, so that the coaxial relative movement is easier to achieve, the stress during sliding is more balanced, and the stability is high. The coal blocking plate 210 is connected to a portion of the second sub-column 242, which is always located outside the first sub-column 241, i.e., can be lifted and lowered along with the sliding of the second sub-column 242. The coal baffle 210 and the second sub-column 242 can be fixedly connected to enhance the stability of the connection; also can adopt the mode of dismantling the connection, be convenient for transportation and later stage fortune dimension.

Optionally, the coal deflector 210 may be partially slidably coupled to the outer wall of the first sub-column 241 to enhance the coupling relationship between the coal deflector 210 and the guide column 240.

In other possible embodiments, the second sub-column 242 is a sleeve structure. The first sub-column 241 is slidably inserted into the second sub-column 242.

The coal deflector 210 is connected to the second sub-column 242.

The principle of this embodiment is the same as that of 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 entire back tail beam assembly 200 is contracted, the overlapping ratio of the first sub-column 241 and the second sub-column 242 is higher, whereas when the entire back tail beam assembly 200 is extended, the total length of the first sub-column 241 and the second sub-column 242 can be longer, i.e. the variable stroke of the guide column 240 is larger.

The inventor of the present application considers that if the coal blocking plate 210 is optimized, a personalized coal discharging mode can be realized. Therefore, the application provides the following possible implementation mode for the supporting equipment:

as shown in fig. 2, the coal blocking plate 210 of the embodiment of the present application includes a plurality of sub-blocking plates 210a, and each sub-blocking plate 210a is correspondingly connected to at least one retractable column 220.

In this embodiment, the sub barriers 210a at different positions may be separately controlled.

Specifically, one or a part of the telescopic columns 220 can be controlled to extend and retract so as to drive the sub-baffle 210a connected with the telescopic columns 220 to lift, thereby realizing the opening and closing of the coal discharge port. Meanwhile, the other telescopic pillars 220 are maintained in a supporting state with respect to the roof beam structure 110, so that the sub-barrier 210a connected to the telescopic pillars 220 maintained in the supporting state is maintained in a state of blocking the discharge of the spoil. According to the operation requirement, the telescopic column 220 which is telescopic and the telescopic column 220 which is kept in the supporting state can be alternatively operated, namely can be alternatively telescopic or kept and supported, 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-barriers 210a, so as to provide a required movement space for each sub-barrier 210a connected to the telescopic beam, and avoid interference between two adjacent sub-barriers 210 a. Optionally, the distance is no greater than the average diameter of the coal or gangue to provide sufficient stopping power.

In some possible embodiments, the sub-barrier 210a extends toward the base 230 and is connected to the base 230.

In this embodiment, the sub-flap 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 shape of the side of the base 230 away from the support post 120 may be adapted to the sub-baffle 210 a. For example, the side of the base 230 away from the supporting post 120 is a plane having the same flatness as the side of the sub-fence 210a facing the mine spoil, or a curved surface having the same curvature.

The inventors of the present application contemplate that modifications to the top beam structure 110 may also provide a gently turning support surface at the aft portion of the top beam structure 110. Therefore, the application provides the following possible implementation mode for the supporting equipment:

as shown in fig. 1, the top beam structure 110 of the embodiment of the present application includes a plurality of top beams 111 and a plurality of connecting members 112.

A number of top beams 111 are parallel to each other and extend towards the rear of the supporting device.

The rear end of the top beam 111 has a bent portion 111a, and the bent portion 111a is bent from the axial direction of the top beam 110 to a direction parallel to the supporting column 120.

The bent parts 111a of two adjacent top beams 111 are connected by a connecting member 112.

One end of the retractable post 220 is connected to one of the end of the bent portion 111a and the connecting member 112, and the connection is a fixed connection or a detachable connection.

An end of the first sub-column 241 of the guiding column 240, which is far away from the second sub-column 242, is connected with the other of the end of the bent portion 111a and the connecting member 112, and the connection is a fixed connection or a detachable connection.

In this embodiment, the top beam structure 110 includes a plurality of top beams 111 for supporting a top plate, the bent portion 111a of the top beam 111 provides a gently-turning support for the top plate at the tail of the top beam structure 110, which is beneficial to the top plate starting to discharge coal or rock at the tail beam assembly 200, and on the other hand, the angle of the retractable column 220 or the guiding column 240 can be met more, so that the retractable column 220 provides a stronger support for the top beam structure 110.

The connection member 112 is connected to the bent portion 111a of the adjacent top beam 111 to improve the strength of the top beam 111 at the bent portion 111a, and the connection member 112 provides a supporting point for the telescopic post 220 or the guide post 240. The connection between the connection member 112 and the bent portion 111a of the adjacent top beam 111 may be a fixed connection or a detachable connection.

It is understood that a bend on the telescoping post 220 and/or the guide post 240 may also be used to achieve a gentle turn between the header structure 110 and the rear tail boom assembly 200.

Optionally, the top beam structure 110 may further include a plurality of joists, the joists are perpendicular to the axial direction of the top beam 111 and are connected to the plurality of top beams 111, and both the top beam 111 and the joists may be rectangular square steel bodies, which may achieve high rigidity and is beneficial to weight reduction.

The inventors of the present application consider that one end of the first sub-column 241 of the guide column 240 needs to be connected with the rear portion of the header structure 110. Therefore, the application provides the following possible implementation mode for the supporting equipment:

one end of the first sub-column 241 of the guide column 240 of the embodiment of the present application is one of fixedly connected and detachably connected to the rear portion of the roof beam structure 110.

In this embodiment, if a fixed connection, for example, 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 have strong stability.

If adopt detachable connection, for example peg graft between the one end of first sub-post 241 and the back timber structure 110, then the connection between first sub-post 241 and the back timber structure 110 possesses detachability, and the form transportation with the split of the supporting equipment of being convenient for reduces the transportation degree of difficulty and cost of transportation, only change whole guide post 240 or first sub-post 241 in the later stage fortune dimension can, be favorable to reducing fortune dimension cost.

Optionally, one end of the retractable column 220 is one of fixedly connected, detachably connected and rotatably connected to the rear portion of the header structure 110, and the other end of the retractable column 220 is rotatably connected to the base 230.

In the present embodiment, if a fixed connection, such as welding, is adopted between one end of the retractable column 220 and the header structure 110, the connection between the retractable column 220 and the header structure 110 can have strong stability.

If adopt detachable connection, for example peg graft between one end of scalable post 220 and the top beam structure 110, then the connection between scalable post 220 and the top beam structure 110 possesses the detachability, is convenient for support equipment and transports with the form of split, reduces the transportation degree of difficulty and cost of transportation, later stage fortune only change in the maintenance scalable post 220 can, be favorable to reducing fortune maintenance cost.

If one end of the retractable column 220 is rotatably connected, for example, hinged, to the top beam structure 110, a certain self-angle adjusting capability can be provided between the retractable 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 ground.

The other end of the telescopic column 220 is rotatably connected, for example, hinged, with the base 230, so that the base 230 has a certain ability of self-adjusting the angle to adapt to uneven roadway ground, the contact area between the base 230 and the roadway ground is increased, and the support stability of the telescopic column 220 to the top beam structure 110 is further increased.

The inventors of the present application have considered that there is a space between the support columns 120 to provide a conveyor with a material carrying channel extending to the rear of the support apparatus. Therefore, the application provides the following possible implementation mode for the supporting equipment:
