[0004] The patent document with the publication number CN209976564U discloses a three-stage isolation paste filling type hydraulic support, which comprises a hydraulic support body and a three-stage isolation plate, the three-stage isolation plate comprises an upper isolation base, an upper isolation movable frame, a middle isolation base, a lower isolation base, and an upper isolation jack and a lower isolation jack; a tail beam is connected with the upper isolation movable frame, and the upper isolation base is hinged with the upper isolation movable frame; the upper isolation base is hinged with the middle isolation base below through the upper isolation jack, forming an upper isolation part; the lower isolation base is connected with the base through the lower isolation jack, forming a lower isolation part. The device forms a sealed space at the rear of the whole isolation, does not need to be lowered to isolate, the slurry cannot enter the telescopic cavity of the isolation plate, and the action of the isolation mechanism is not affected by the paste, solving the problem that the slurry leakage affects the work of the hydraulic support in the process of paste filling.

[0005] The patent document with the publication number CN214007193U discloses a parallel paste filling hydraulic support, which is a four-column support shield type hydraulic support, and is provided with upper and lower isolations at the rear part. The upper isolation is driven by the upper swing control top beam isolation connecting rod to seal the coal seam roof. The rear frame tail beam is controlled by the rear frame tail beam swing control jack to seal the coal seam roof. The lower isolation is controlled by the lower isolation telescopic jack to seal the coal seam floor. The rear frame base and the front and rear frame connecting head are hinged to the rear frame base.

The advantages are that the coal mining and filling operation are independent of each other, the filling operation can quickly isolate the mining working face in a mechanical manner, and the artificial workload is reduced. The problem of contradiction between coal mining and filling operation in the paste filling mining process is solved.

[0006] However, the above-mentioned parallel paste filling hydraulic support still has the following problems:

[0007] 1. There is a time difference between mining and filling operation, that is, mining is faster, and filling often needs a longer time (6-8 hours) to remove the isolation plate after the paste solidifies. The hydraulic support needs to be moved after the paste solidifies, which affects the mining efficiency.

[0008] 2. The upper and lower telescopic plates have poor sealing performance and have certain gaps that are easy to leak liquid, especially the lower telescopic isolation plate, which is a whole. When the ground has a certain slope, the lower telescopic isolation plate and the ground cannot achieve good sealing, which affects filling.

[0009] 3. The isolation plate and the whole support are not separated but connected by a certain structure, so they affect each other during mining and filling operation. SUMMARY

[0025] Furthermore, the upper surfaces of the first buffer plate and the second buffer plate are in contact with the first connecting plate and the second connecting plate, respectively. The lower surfaces of the first buffer plate and the second buffer plate include two inclined sections, which are distributed on both sides of the hinge point between the corresponding buffer plate and the corresponding baffle.

[0046] The principles and features of the present invention are described below. The embodiments given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0047] As shown in the attached figure, the high-efficiency sampling and filling parallel hydraulic support of this embodiment includes a tail beam 1 hinged to the tail of the hydraulic support. A support 16 is provided on the front side of the tail beam 1. The hydraulic support is connected to the support 16 through a tail beam jack 17.

[0048] The aforementioned parallel hydraulic support also includes a rear telescopic beam 2, an isolation baffle 3, an isolation cloth 4, a telescopic beam jack 5, an upper limit jack 6, a lower limit jack 7, a lower limit swing jack 8, a baffle adjustment jack 9, and an isolation cloth tensioning jack 10.

[0049] The isolation baffle 3 is configured as an upper and lower telescopic baffle; specifically, the isolation baffle 3 includes a rear baffle 30 and an upper baffle 31 and a lower baffle 32 located in front of the rear baffle 30. The upper baffle 31 and the lower baffle 32 are slidably connected to the rear baffle 30 in the vertical direction. The rear baffle 30 is respectively provided with an upper telescopic jack 33 and a lower telescopic jack 34 for driving the upper baffle 31 and the lower baffle 32 to slide. Sealing blocks 11 are provided at the top of the upper baffle 31 and the bottom of the lower baffle 32. Adjacent rear baffles 30 are hinged to each other, such as... Figure 7 As shown, the rear baffles of the entire working face are connected end to end; the connecting lugs 19 between the rear baffles 30 adopt a long hole 20 structure, see Figure 8 and Figure 9 The increased clearance between the ear plates enhances adaptability to the top and bottom plates;

[0050] The rear telescopic beam 2 is connected to the tail beam 1 by relative sliding.

[0051] The telescopic beam jack 5 is connected between the telescopic beam and the tail beam 1, and is used to drive the rear telescopic beam 2 to move relative to the tail beam 1.

[0052] The cylinder of the upper limit jack 6 is fixed on the rear telescopic beam 2. Its telescopic end is horizontally facing the upper part of the isolation baffle 3 and maintaining a constant distance from the upper isolation baffle. It is normally in the retracted state and fully extended when preparing to fill.

[0053] One end of the lower limit jack 7 is connected to the tail beam 1, and the other end is used to connect to the lower part of the isolation baffle 3 under the working loading.

[0054] One end of the lower limit swing jack 8 is connected to the tail beam 1, and the other end is connected to the cylinder of the lower limit jack 7, which is used to adjust the swing amplitude of the lower limit jack 7.

[0055] The baffle adjusting jack 9 is arranged at the rear side of the lower limiting jack 7, one end of which is connected to the rear telescopic beam 2, and the other end is connected to the isolation baffle 3.

[0056] The isolation cloth tensioning jack 10 is fixed on the cylinder barrel of the lower limiting jack 7, and the telescopic end thereof is connected to the isolation cloth 4, and the other end of the isolation cloth 4 is fixed on the front end of the top of the isolation baffle 3 by passing around the bottom of the isolation baffle 3, the rear side of the isolation baffle 3 and the top of the isolation baffle 3.

[0057] The mining and filling method of the present application:

[0058] In the filling operation state: the upper limiting jack 6 is extended to abut against the upper part of the isolation baffle 3, the lower limiting jack 7 is extended to abut against the lower part of the isolation baffle 3, and the baffle adjusting jack 9 is extended to abut against the middle part of the isolation baffle 3, so that the top and bottom of the isolation baffle 3 abut against the roadway to form a filling sealing baffle wall;

[0059] In the non-filling operation state: the upper limiting jack 6 is retracted, the lower limiting jack 7 is released from the isolation baffle 3, and the upper and lower retraction of the isolation baffle 3 is released from the abutment of the sealing block 11 at the top and bottom of the isolation baffle 3 to the roadway;

[0060] In the mining and filling parallel operation state: during the whole forward movement of the hydraulic support with the tail beam 1 and the rear filling operation, the rear telescopic beam 2 is extended from the rear of the tail beam 1 under the action of the telescopic beam jack 5, the telescopic end of the upper limiting jack 6 always abuts against the upper part of the isolation baffle 3, the telescopic end of the lower limiting jack 7 is further elongated and adjusted in swing range under the driving of the lower limiting swing jack 8, so that the end of the lower limiting jack 7 always abuts against the lower part of the isolation baffle 3, and the top and bottom of the isolation baffle 3 are stably abutted against the roadway to form a filling sealing baffle wall; after the filling is completed, the isolation baffle 3 returns to the non-filling operation state, and the rear telescopic beam 2 is retracted into the tail beam 1 under the action of the telescopic beam jack 5.

[0061] When the hydraulic support is in the process of top beam falling, the baffle adjusting jack is retracted to form linkage to prevent damage to the isolation baffle during falling. The push-pull cylinder (controlling the forward movement of the support) on the base of the hydraulic support and the rear telescopic beam are linked, in order to ensure the integrity and verticality of the rear baffle, when the push-pull cylinder is retracted during the forward movement of the support, the rear telescopic beam cylinder must be extended, and the stroke is synchronous to maintain the integrity of the rear isolation baffle. When the support is completely moved into position, the isolation baffle is retracted through electro-hydraulic control.

[0062] In a preferred embodiment of the present application, the lower baffle 32 is composed of a left baffle 321 and a right baffle 322 which are independent of each other, the left baffle 321 and the right baffle 322 are respectively connected to independent lower telescopic jacks 34, and the sealing block 11 at the bottom of the lower baffle 32 is connected to the left baffle 321 and the right baffle 322 through the connecting frame 110. The inner side of the sealing block 11 is provided with a connecting seat 12 for connecting with the lower limiting jack 7.

[0063] The above-mentioned left baffle 321 and right baffle 322 are independent of each other and are controlled by independent lower telescopic jacks, and the hinged connection relationship between the bottom sealing block 11 and the left and right baffles can improve the grounding performance of the sealing block, as shown in Figure 6 When one end of the sealing block is grounded, the oil cylinder is in place, and the other end of the oil cylinder continues to extend to rotate around the hinge pin shaft until the rubber strip is pressed tightly, so that the sealing block can adapt to the ground in different working conditions and ensure the sealing effect.

[0064] In a preferred embodiment of the present application, the telescopic end of the lower limit jack 7 is provided with a ball head structure, and the connecting seat 12 is provided with a ball socket 120 matched with the telescopic end of the lower limit jack 7. The lower limit jack 7 can further adapt to the sealing block through hinged rotation to adapt to the ground, and this structure can realize quick disassembly of the lower limit jack 7 and the ball socket 120, which is conducive to quick recovery of the isolation baffle 3 and avoids manual operation during the process.

[0065] In a preferred embodiment of the present application, the left baffle 321 is fixedly connected with a first connecting plate 131 connected with the telescopic end of the corresponding lower telescopic jack 34, and the first connecting plate 131 is connected with the first buffer plate 141 hinged to the left baffle 321; the right baffle 322 is fixedly connected with a second connecting plate 132 connected with the telescopic end of the corresponding lower telescopic jack 34, and the second connecting plate 132 is connected with the second buffer plate 142 hinged to the right baffle 322. The upper end surfaces of the first buffer plate 141 and the second buffer plate 142 respectively contact the first connecting plate 131 and the second connecting plate 132, and the lower end surfaces of the first buffer plate 141 and the second buffer plate 142 include two inclined surface segments distributed on both sides of the hinge joint of the corresponding buffer plate and the corresponding baffle, and the width of the buffer plate shows a narrowing trend from the hinge joint to both ends of the buffer plate.

[0066] Through the special structural design of the two buffer plates and the hinged relationship with the left and right baffles and the connection relationship with the sealing block, the corresponding buffer plate can adaptively rotate with the hinged rotation of the sealing block, so that the upper and lower ends of the buffer plate are always in contact with the corresponding connecting plate and the sealing block ball socket, respectively, thereby enhancing the sealing effect of the lower side of the ball socket and the inner side of the sealing block, reducing the bearing pressure of the hinge shaft of the connecting frame and the left and right baffles, and improving the service life of the workpiece. The bottom sealing block of the present embodiment adopts a labyrinth elastic sealing rubber strip with an upper end surface shaped as " " and a bottom end surface with a concave-convex structure. Through the additional ball socket matched with the lower limit jack, and in combination with the structure and connection relationship of the left and right baffles and the two buffer plates, the contact surface can be pressed tightly regardless of whether it is flat or not, thereby preventing liquid leakage and ensuring the adaptability of the support.

[0067] In a preferred embodiment of the present application, the telescopic end of the isolation cloth tension jack 10 is connected with the isolation cloth 4 through a tension spring 15, which is beneficial to the adaptive cooperation of the isolation cloth with the isolation baffle during the forward movement of the hydraulic support. When the isolation baffle is extended, the isolation cloth is unfolded, and when the height reaches the requirement, the isolation cloth is automatically retracted through the cloth retraction jack. The isolation cloth tension jack 10 is suspended below the lower limit jack, which saves space and is convenient to manage.
