Description

Technical Field

[0001] This utility model relates to the field of paste and gangue filling technology for high mining height, and in particular to an isolation retaining wall for paste filling. Background Technology

[0002] The high-extraction paste and gangue backfilling technology involves processing solid wastes such as coal gangue, fly ash from power plants, and industrial slag generated during coal mining into slurry-like backfilling materials on the ground. These materials are then pressurized by a dedicated backfilling pump and transported underground through backfilling pipelines to fill the already mined mine pits.

[0003] The erection of the retaining wall in the area to be filled in the mine pit is affected by the mining height. The height of each working face is different. When the height is high, the height of one retaining wall cannot meet the erection requirements, so the retaining wall needs to be increased. In the existing construction process, most of the time, the binding and bolt fastening methods are used to fix another retaining wall on top of one retaining wall. The binding process is cumbersome and reduces the erection efficiency. Summary of the Invention

[0004] To address the problem that existing construction methods mostly rely on binding and bolting to fix one retaining wall above another, reducing support efficiency, this invention proposes an isolation baffle for paste filling. By adjusting the vertical distance between the second retaining wall and the first retaining wall, the height of the sealing wall can be quickly increased, improving the filling efficiency of the mine pit.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] An isolation barrier for filling paste includes a first barrier and a second barrier, with the second barrier located above the first barrier. A slot is provided at the upper end of the first barrier, and a telescopic part is fixed to the lower end of the second barrier, inserting into the slot. The vertical distance between the second barrier and the first barrier is adjustable. Multiple third barriers, arranged vertically in sequence, are provided on the side of the telescopic part near the support surfaces of the first and second barriers, inserting into the slots. The distance between the third barriers and the telescopic part is adjustable. A diagonal support is hinged to the side of the first barrier away from the support surface. The adjustable distance between the third barriers and the telescopic part allows the support surfaces of the first, second, and third barriers to be flush. Multiple third barriers accommodate working surfaces of different heights.

[0007] Furthermore, a first limiting part is fixed to the side of the first retaining wall away from the support surface, and a second limiting part is fixed to the side of the second retaining wall away from the support surface. Both the first and second limiting parts have multiple mutually cooperating limiting holes, through which pins pass. The vertical position of the second retaining wall is adjusted by the cooperation of these multiple limiting holes.

[0008] Further, the part of the second limiting portion cooperating with the first limiting portion is in an inverted "U" shape and is located on both sides of the first limiting portion, which improves the stability of the second retaining wall.

[0009] Further, the distance between the axes of the adjacent limiting holes above and below is equal to the height of one of the third retaining walls.

[0010] Further, a plurality of distance adjusting mechanisms cooperating with the third retaining wall are successively arranged in the telescopic portion from top to bottom. The distance adjusting mechanism includes an adjusting rod, a fastening member and a limiting member. A first opening is provided on one side of the telescopic portion away from the third retaining wall. A limiting disk is fixed on one side of the third retaining wall away from the telescopic portion. A second opening is provided on one side of the limiting disk close to the third retaining wall. The fastening member is fixed in the first opening. One end of the adjusting rod sequentially passes through the first opening, the fastening member and the third retaining wall and its end is fixedly connected with the limiting member. The limiting member is located in the second opening. The outer diameter of the limiting member is larger than the outer diameter of the adjusting rod. The other end of the adjusting rod is located in the first opening. The fastening member is threadedly connected with the adjusting rod. Manually rotate the adjusting rod, and the adjusting rod threadedly connected with the fastening member rotates and moves towards the third retaining wall, pushing out the third retaining wall so that the supporting surfaces of the first retaining wall, the second retaining wall and the third retaining wall are flush.

[0011] Further, the longitudinal section of the first opening is in an inverted "convex" shape, and the fastening member is fixed at the convex part of the first opening, which is convenient for manual use of tools to enter the first opening to screw the adjusting rod.

[0012] Further, the fastening member is a nut and the adjusting rod is a set screw.

[0013] Further, the limiting disk includes a first limiting body fixed on the side surface of the third retaining wall and a second limiting body fixedly connected with the first limiting body. The second opening is provided on one side of the first limiting body away from the third retaining wall, which is convenient for manual installation of the adjusting rod.

[0014] Further, the longitudinal section of the second opening is in an inverted "convex" shape.

[0015] By the above technical solutions, the beneficial effects of the present utility model are as follows: The present utility model adjusts the distance of the second retaining wall relative to the first retaining wall by the cooperation of the second limiting portion and the limiting holes on the first limiting portion with a pin shaft, quickly realizes the increase of the height of the plugging wall, improves the landfill efficiency of the mine pit. After the distance at one end of the second retaining wall is increased, the telescopic portion rises a certain distance. At this time, the third retaining wall is exposed. When the height of the second retaining wall meets the height of the pouring working surface, manually rotate the adjusting rod, and the adjusting rod threadedly connected with the fastening member rotates and moves towards the third retaining wall, pushing out the third retaining wall so that the supporting surfaces of the first retaining wall, the second retaining wall and the third retaining wall are flush, ensuring the flatness of the side surface of the pouring working surface.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0023] like Figures 1-5 As shown, this embodiment provides an isolation barrier for filling paste, including a first barrier 1 and a second barrier 2. The second barrier 2 is located above the first barrier 1. The upper end of the first barrier 1 is provided with a slot 3. The lower end of the second barrier 2 is fixed with a telescopic part 4, which is inserted into the slot 3. The vertical distance between the second barrier 2 and the first barrier 1 is adjustable.

[0024] Specifically, a first limiting part 8 is fixed on the side of the first retaining wall 1 away from the support surface 5, and a second limiting part 9 is fixed on the side of the second retaining wall 2 away from the support surface 5. Both the first limiting part 8 and the second limiting part 9 have multiple mutually cooperating limiting holes 10, and pins 11 pass through the limiting holes 10. When height adjustment is required, the part is manually pulled out. Figure 1The pin 11 in the middle raises the height of the second retaining wall 2. When the appropriate height is reached, the pin 11 is inserted into the limiting hole 10 of the first limiting part 8 and the second limiting part 9 that cooperate with each other to fix the height of the second retaining wall 2.

[0025] The portion of the second limiting part 9 that cooperates with the first limiting part 8 is inverted "U" shape and located on both sides of the first limiting part 8.

[0026] In this embodiment, the distance between the axes of adjacent vertically spaced limiting holes 10 is equal to the height of one of the third retaining walls 6. In other possible embodiments, the vertical distance between the second retaining wall 2 and the first retaining wall 1 can be adjusted by connecting a slider and a groove. In this case, the position adjustment of the second retaining wall 2 will have a higher degree of freedom, so as to facilitate the protrusion of the third retaining wall 6. It should also be understood that the height of the second retaining wall 2 is slightly higher than the height of the working surface, so an appropriate height of the second retaining wall 2 is selected to allow multiple third retaining walls 6 to protrude.

[0027] Furthermore, the telescopic part 4 is provided with a plurality of third retaining walls 6 arranged vertically on the side of the support surface 5 near the first retaining wall 1 and the second retaining wall 2. The third retaining walls 6 are inserted into the slot 3, and the distance between the third retaining walls 6 and the telescopic part 4 is adjustable.

[0028] Specifically, the telescopic part 4 is provided with a plurality of adjusting mechanisms that cooperate with the third retaining wall 6 from top to bottom. The adjusting mechanism includes an adjusting rod 12, a fastener 13 and a limiting member 14. The telescopic part 4 is provided with a first opening 15 on the side away from the third retaining wall 6. The third retaining wall 6 is fixed with a limiting plate 17 on the side away from the telescopic part 4. The limiting plate 17 is provided with a second opening 16 on the side close to the third retaining wall 6.

[0029] The fastener 13 is fixed in the first opening 15. One end of the adjusting rod 12 passes sequentially through the first opening 15, the fastener 13, and the third retaining wall 6, and its end is fixedly connected to the limiting member 14. The limiting member 14 is located in the second opening 16, and its outer diameter is larger than that of the adjusting rod 12. The other end of the adjusting rod 12 is located inside the first opening 15. The fastener 13 is threadedly connected to the adjusting rod 12. When the adjusting rod 12 is manually rotated, it pushes against the third retaining wall 6. The other end of the adjusting rod 12 is located inside the first opening 15 and does not affect the retraction of the telescopic part 4 into the slot 3.

[0030] In this embodiment, a baffle can also be fixed on one side of the support surface 5 of the first retaining wall 1 to limit the position of the third retaining wall 6, so that the third retaining wall 6 can no longer be pushed when it is flush with the first retaining wall 1 and the second retaining wall 2.

[0031] It should be noted that the side surface of the third retaining wall 6 in this device is not completely flush with the side walls of the first retaining wall 1 and the second retaining wall 2. During actual use, the rubber sponge can be cut to a suitable size to fill the gap and prevent leakage during pouring.

[0032] In this embodiment, the adjusting rod 12 is a setscrew and the fastener 13 is a nut.

[0033] The longitudinal section of the second opening 16 is in an inverted "convex" shape, and at the same time, the outer diameter of the limiting member 14 is larger than the outer diameter of the adjusting rod 12. As Figure 5 shown, the limiting member 14 is blocked in the second opening 16 to facilitate pulling the third retaining wall 6 back to its original position later. In order to place the limiting member 14 into the second opening 16, the limiting disc 17 includes a first limiting body fixed to the side surface of the third retaining wall 6 and a second limiting body fixedly connected to the first limiting body. The second opening 16 is opened on the side of the first limiting body away from the third retaining wall 6. The first limiting body and the second limiting body are bolted and fixed.

[0034] The longitudinal section of the first opening 15 is in an inverted "convex" shape, and the fastener 13 is fixed at the convex part of the first opening 15. This facilitates manual use of tools to reach into the second opening 16 and rotate the adjusting rod 12.

[0035] An inclined support 7 is hinged to the side of the first retaining wall 1 away from the support surface 5. This facilitates the support of the isolation retaining wall.

[0036] During use, manually pull out the pin shaft 11 and lift the height of the second retaining wall 2. When at an appropriate height, insert the pin shaft 11 into the limiting holes 10 of the mutually cooperating first limiting portion 8 and the second limiting portion 9 to fix the height of the second retaining wall 2. At this time, at least one third retaining wall 6 will be exposed. Manually use tools to rotate the adjusting rod 12, and the adjusting rod 12 threadedly connected to the fastener 13 rotates and moves in the direction of the third retaining wall 6 to push out the third retaining wall 6 so that the support surfaces of the first retaining wall 1, the second retaining wall 2 and the third retaining wall 6 are flush. Then, after setting up multiple isolation retaining walls and connecting them into one body, the pouring operation can be started.

[0037] The above-described embodiments are only the preferred embodiments of the present invention and do not limit the scope of implementation of the present invention. Therefore, all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent should be included within the scope of the patent application of the present invention.
