Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of mine tunnel filling, and in particular, to a filling support. Background Art
[0002] In underground coal mines, paste filling mining is mainly based on mining "three-down" compressed coal to minimize the surface settlement and minimize the damage to surface structures caused by surface settlement. Paste filling mining is to use comprehensive mechanized coal mining technology to complete "three-down" compressed coal mining, and then use the paste filling technology to fill the space after the coal is mined with concrete paste. After the concrete paste solidifies, it replaces the coal seam to achieve the support effect on the roof and floor of the original coal seam.
[0003] During paste filling mining, the filling hydraulic support plays the role of supporting the space and isolating the filling space. The filling support in the related technology is provided with a support tail beam. When the support tail beam is fully opened to connect the top, it is used to temporarily support the top plate of the filling space, so as to facilitate the safe operation of the workers in the filling space; after the support tail beam is lowered to vertical, it forms an isolation skeleton together with the bottom sealing beam, which fully separates the filling space from the working space. During operation, the support tail beam needs to be gradually retracted, and wooden columns are used to temporarily support the coal seam roof of the filling space, that is, temporary support is required before supporting the top plate of the filling space, which increases the support operation links, prolongs the support operation cycle, and leads to a significant increase in the single filling cycle.

[0027] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.
[0028] In the present disclosure, unless otherwise stated, the directional words used, such as "upper, lower, top, and bottom", generally refer to the upper, lower, top, and bottom of the corresponding component in the direction of gravity when in use, and "inside and outside" refer to the inside and outside relative to the outline of the component or structure itself. In addition, it should be noted that the terms used, such as "first, second", etc., are used to distinguish one element from another, and do not have order and importance. In addition, in the description with reference to the drawings, the same mark in different drawings represents the same element.
[0029] like Figure 1-2 As shown, the present disclosure provides a filling support for being arranged in a mine tunnel, the filling support comprises a base 1, a top beam 2 and a supporting device 3 connected between the base 1 and the top beam 2, a pushing device is provided on the base 1 for moving the filling support, for example, the pushing device is a roller, the supporting device 3 comprises a hydraulic lifting rod and a connecting rod mechanism, the connecting rod mechanism forms a four-link mechanism with the top beam 2 and the base 1, for improving the stability of the hydraulic lifting rod during support, the filling support also comprises: an isolation component 4, which is arranged between the top beam 2 and the base 1 and is located at the ends of the top beam 2 and the base 1 to isolate the filling space; an operating hole 22 for the anchor rod 5 to pass through and a net roll groove 21 for placing a protective net are provided on the top beam 2, an installation window 23 is provided at one end of the net roll groove 21 close to the isolation component 4, and an anchor machine fixing hole 101 corresponding to the operating hole 22 is provided on the base 1, so that the operating space is located below the top beam 2.
[0030] Through the above technical scheme, an operation hole 22 and a mesh roll groove 21 are provided on the top beam 2, and an anchor machine fixing hole 101 is provided on the base 1. During operation, the anchor machine is fixed in the anchor machine fixing hole 101, and the operation hole 22 is used to drill and install the anchor 5. After the anchor 5 is installed, the protective net is laid in the mesh roll groove 21 through the installation window 23, and then the filling bracket is moved forward so that the installation window 23 corresponds to the nearest group of anchors 5. The worker uses the installation window 23 to put the protective net on the anchor 5 and install the anchor tray, and then continues to move the filling bracket forward until the protective net is connected to all the anchors 5 to complete the support. In this way, the working space can be located below the top beam 2, and the workers can carry out construction under the protection of the top beam 2 without adding temporary support, thereby significantly improving the working efficiency.
[0031] As an optional implementation, Figure 1 and Figure 3 As shown, the isolation assembly 4 includes an upper sealing beam 42, a bottom sealing beam 41 and a middle sealing plate 43. The upper sealing beam 42 is arranged on the top beam 2 along the height direction and extends downward, the bottom sealing beam 41 is arranged on the base 1 along the height direction and extends upward, and the middle sealing plate 43 is arranged between the upper sealing beam 42 and the bottom sealing beam 41. The upper sealing beam 42 is provided with a grouting hole for connecting a grouting pipe to inject concrete paste into the filling space. Since the support tail beam in the related art is a rotating structural member and needs to temporarily support the top plate, it needs to be equipped with a hydraulic drive system for rotation. Its thickness is generally about 0.4m, so its weight is relatively large. When the support tail beam overlaps the bottom sealing beam 41, the bottom sealing beam 41 needs to offset the force when the support tail beam rotates and contacts itself, so the thickness of the bottom sealing beam 41 is also relatively thick, resulting in its relatively large weight. The present invention does not need a bracket tail beam for temporary support, so there is no need to rotate the bracket tail beam, the hydraulic drive system is cancelled, and a middle sealing plate 43 is provided between the upper sealing beam 42 and the bottom sealing beam 41, so as to shorten the height of the upper sealing beam 42 and the bottom sealing beam 41, and reduce the weight of the upper sealing beam 42 and the bottom sealing beam 41. The height of the upper sealing beam 42 is reduced from about 3m to less than 1m. Since no temporary support is required, the thickness is reduced from about 0.4m to 0.2m, and the weight is significantly reduced. The bottom sealing beam 41 no longer needs to offset the rotational force of the upper sealing beam 42, so the thickness of the bottom sealing beam 41 can also be reduced.
[0032] Optionally, the upper sealing beam 42 is detachably connected to the top beam 2, the bottom sealing beam 41 is detachably connected to the base 1, and the middle sealing plate 43 is detachably connected to at least one of the upper sealing beam 42 or the bottom sealing beam 41, for example, detachably connected by a pin shaft. This is convenient for the installation, maintenance and replacement of the internal facilities of the upper sealing beam 42 and the bottom sealing beam 41, and for the maintenance and replacement of the upper sealing beam 42 and the bottom sealing beam 41 themselves. Moreover, when the mining height of the working face changes greatly, it is only necessary to replace the middle sealing plate 43, and there is no need to replace the upper sealing beam 42 and the bottom sealing beam 41 in batches.
[0033] As an optional implementation, Figure 3-4 As shown, the isolation assembly 4 is provided with an isolation outlet 44, for example, it is arranged on the lower bottom sealing beam 41, and an openable baffle 45 is arranged at the isolation outlet 44. The isolation outlet 44 is used for operators to leave the filling space. After leaving, the isolation outlet 44 is blocked by the baffle 45, which does not hinder the isolation of the isolation assembly 4, and there is no need to fully open the isolation assembly 4. A square rubber pad is installed at the isolation outlet 44 and superimposed on the isolation membrane 46. The baffle 45 is installed with a fixing rod. Active plates 47 are arranged on the upper and lower sides of the isolation outlet 44 for connecting the fixing rods. The active plates 47 are installed on the bottom sealing beam 41 by bolts. The mounting hole of the upper active plate 47 is L-shaped. When the baffle 45 is not installed, the upper active plate 47 is opened. The movable plate 47 on the side moves upward and then translates to be hung on the horizontal part of the L-shaped mounting hole. The mounting hole of the movable plate 47 on the lower side is a vertical strip. When the baffle 45 is not installed, the top of the mounting hole is hung on the bolt under the action of gravity. When the baffle 45 needs to be installed, the upper movable plate 47 is translated to make it fall, and the lower movable plate 47 is lifted to raise it. Then, the fixing rod on the baffle 45 is passed through the mounting hole on the movable plate 47 and then tightened with a nut to fix the baffle 45. The movable plate 47 is set to make the square rubber pad press on the isolation membrane 46 of the isolation outlet 44. There is no need to open a mounting hole on the square rubber pad, thereby avoiding weak isolation links and slurry leakage accidents.
[0034] As an optional implementation, Figure 1 and Figure 3-5 As shown, the isolation assembly 4 also includes an isolation membrane 46, and the filling bracket also includes a clamping device 6. The isolation membrane 46 is arranged on the side of the upper sealing beam 42 close to the filling space and extends from the top beam 2 to the base 1. The clamping device 6 can be raised and lowered at the upper and lower ends of the isolation assembly 4 to clamp and fix the isolation membrane 46. The isolation membrane 46 is arranged on the side of the upper sealing beam 42, the middle sealing plate 43 and the bottom sealing beam 41 close to the filling space to play an isolation and sealing role. In the related art, in order to lay and fix the top edge of the isolation membrane 46, it is necessary to lower the tail of the bracket top beam, and fix the top edge of the isolation membrane 46 by squeezing the top edge of the isolation membrane 46 by the bracket tail beam, while the bottom edge needs to be fixed by digging trenches and filling soil. The operation is complicated and the fixation is not firm, and the slurry will leak. The present disclosure uses the clamping device 6 to clamp and fix the upper and lower sides of the isolation membrane 46 to prevent gaps from appearing between the isolation membrane 46 and the top plate and the bottom plate.
[0035] Among them, Figure 3-4As shown, the clamping device 6 includes a lifting device 61 and an elastic device 62. The lifting device 61 is connected to the elastic device 62 to drive the elastic device 62 to clamp and fix the isolation membrane 46. The lifting device 61 drives the elastic device 62 to move and contact the isolation membrane 46. When potholes and waves appear locally on the top and bottom plates, the contraction and release of the elastic device 62 are used to fully clamp the edges of the isolation membrane 46, so as to achieve the purpose of reliably fixing the top and bottom edges of the isolation membrane 46.
[0036] Alternatively, if Figure 5 As shown, the filling bracket also includes a mounting seat 628, the elastic device 62 includes an inner sleeve 622, an outer sleeve 621, a first pressure plate 623, a limiting bolt 627 and a spring 624, the outer sleeve 621 is arranged on the mounting seat 628, for example, the lifting device 61 is a hydraulic lifting column, and the mounting seat 628 is provided with a fixing groove on the side close to the lifting device 61, the end of the hydraulic lifting column is clamped in the fixing groove, the inner sleeve 622 is sleeved in the outer sleeve 621, and a strip limiting hole 626 is opened on the outer sleeve 621 along the height direction, the limiting bolt 627 passes through the strip limiting hole 626 and is connected with the inner sleeve 622, the inner sleeve 622 moves up and down along the strip limiting hole 626 through the limiting bolt 627 to prevent the inner sleeve 622 from separating from the outer sleeve 621, and the first A pressure plate 623 is set at one end of the inner sleeve 622 away from the outer sleeve 621, which is used to compress the isolation membrane 46. A fixing seat 625 is provided at the bottom center of the outer sleeve 621. The spring 624 is sleeved on the outside of the fixing seat 625 and extends into the inner sleeve 622 to contact the first pressure plate 623. Because the spring 624 needs to extend into the inner sleeve 622, and the diameter of the outer sleeve 621 is larger than the inner sleeve 622, there will be a gap between the spring 624 and the outer sleeve 621. Therefore, the spring 624 is sleeved on the fixing seat 625 to position the spring 624 to prevent the spring 624 from shaking. The top of the fixing seat 625 is open and the mounting seat 628 and the fixing seat 625 are provided with ash seepage holes 629 to prevent dust accumulation in the mounting seat 628 and the outer sleeve 621.
[0037] Alternatively, if Figure 3-4 As shown, the filling bracket also includes an elastic diaphragm protection member 7, which is arranged on the upper and lower sides of the edge of the isolation membrane 46. For example, the diaphragm protection member 7 is constructed as an elastic strip, and two groups can be provided, which are respectively arranged on the upper and lower sides of the edge of the isolation membrane 46 to clamp the isolation membrane 46. On the one hand, the isolation membrane 46 can be protected to prevent the isolation membrane 46 from being damaged; on the other hand, it can be further fitted with the top plate and the bottom plate to enhance the isolation and sealing effect.
[0038] In addition, if Figure 6-7As shown, the filling bracket also includes an auxiliary stacking device 8. A plurality of filling brackets are arranged side by side. The auxiliary stacking device 8 is arranged on the upper and lower sides between two adjacent isolation components 4. Since the mine tunnel is wide, multiple filling brackets need to be arranged side by side. In order to seal more tightly, a complete isolation membrane 46 is required to contact multiple filling brackets. There will be a gap between two adjacent filling brackets, which will make the top and bottom edges of the isolation membrane 46 not tightly sealed. Therefore, an auxiliary stacking device 8 is required to press and fix the sealing membrane between the two isolation components 4.
[0039] Optionally, the auxiliary lamination device 8 includes a support plate 82, a mounting plate 83, a strut 81, a pre-tightening nut 84 and a second pressing plate 85, the support plate 82 is arranged on the isolation assembly 4 and the support plates 82 on two adjacent isolation assemblies 4 are arranged relatively spaced apart, the mounting plate 83 is arranged between the two support plates 82, a snap ring 831 is provided on one side edge of the mounting plate 83 and is perpendicular to the mounting plate 83, one end of the mounting plate 83 is sleeved with one of the support plates 82 through the snap ring 831, and the other end is abutted with the adjacent support plate 82, a through hole 832 is provided on the mounting plate 83, one end of the strut 81 passes through the through hole 832 and is connected to the second pressing plate 85. The second pressure plate 85 and the other end of the support rod 81 are provided with a limit piece, for example, the support rod 81 is L-shaped, and the L-shaped cross bar part serves as a limit piece to prevent the mounting plate 83 from being separated from the support rod 81. The pre-tightening nut 84 is threadedly connected to the portion of the support rod 81 located between the second pressure plate 85 and the mounting plate 83. The support rod 81 is a screw rod. When tightening is required, the pre-tightening nut 84 is rotated to move the pre-tightening nut 84 toward the mounting plate 83. The pre-tightening nut 84 presses the mounting plate 83 against the support plate 82 to fix the mounting plate 83. At the same time, rotating the pre-tightening nut 84 will also move the support rod 81 toward the isolation membrane 46 to tighten the isolation membrane 46.
