Description

Technical Field

[0001] The invention belongs to the technical field of coal mining tunnel filling, and in particular relates to a multifunctional rapid partition device used for coal mine tunnel filling. Background Art

[0002] As coal mining depth increases, overburden movement, surface subsidence, and subsidence area management issues caused by goafs are becoming increasingly prominent, becoming a key technical bottleneck restricting the sustainable development of coal-producing areas. To avoid the formation of goafs, new mining schemes that coordinate coal mining with tunnel filling are gaining attention. Practice has shown that this new mining scheme exhibits significant technical advantages. However, the paste filling process faces three major technical challenges: First, in steeply inclined mining tunnels, the lateral pressure of the paste is extremely high as the filling progresses, which can easily cause the sealing equipment or structure to slide or collapse, resulting in catastrophic slurry leakage. Second, the operation of traditional sealing and isolation equipment and methods is complex, which limits filling efficiency and makes it difficult to achieve continuous and efficient operation. Third, traditional sealing and isolation operations are largely manual, posing safety risks. Fourth, when filling steeply inclined tunnels, existing sealing equipment cannot meet the grouting requirements due to the large drop in steeply inclined tunnels.

[0003] Therefore, it is necessary to provide an improved technical solution to the above-mentioned deficiencies in the prior art. Invention content

[0056] A telescopic jack 13 is provided between the main frame and the auxiliary frame. One end of the telescopic jack 13 is hinged to the inner side of the main frame, and the other end is hinged to the inner side of the auxiliary frame.

[0057] In one embodiment of the present application, the telescopic jack 13 is controlled to perform telescopic movement, so that the sub-frame performs telescopic movement relative to the main frame, thereby achieving adjustment of the length direction of the telescopic frame.

[0058] A cross bracing mechanism 9 is provided between two sub-frames arranged facing each other in the transverse direction. One end of the cross bracing mechanism 9 is hinged to one sub-frame, and the other end is hinged to the other opposite sub-frame.

[0059] In one embodiment of the present application, a cross bracing mechanism 9 is provided between the sub-frame of the left front frame 1 and the sub-frame of the right front frame 2, and a cross bracing mechanism 9 is provided between the sub-frame of the left rear frame 3 and the sub-frame of the right rear frame 4.

The protrusions are located in the guide holes of the card strip 25, so that each bottom plate can be guided and moved along the card strip 25; when the position of each bottom plate in the bottom plate system is adjusted into place, the card strip 25 serves to limit each bottom plate, which can ensure that the bottom plate system has good stability.

[0068] The main frame includes a plurality of main beams 10 and a plurality of cross beams 12 . The plurality of main beams 10 are arranged in parallel. The plurality of cross beams 12 are perpendicular to the main beams 10 . The plurality of main beams 10 are fixedly connected by the cross beams 12 .

[0069] A hinge seat 26 is provided on the left front bottom plate 17 , the left rear bottom plate 19 , the right front bottom plate 18 and the right rear bottom plate 20 , and the bottom end of each main beam 10 is hinged to a hinge seat 26 .

[0070] The sub-frame includes a plurality of sliding beams 11 and a plurality of cross beams 12 . The plurality of sliding beams 11 are arranged in parallel. The plurality of cross beams 12 are perpendicular to the sliding beams 11 . The plurality of sliding beams 11 are fixedly connected by the cross beams 12 .

[0071] The sliding beams 11 are hollow structures. Each sliding beam 11 is sleeved on the upper portion of a main beam 10 , and the sliding beam 11 slides along the guide of the main beam 10 .

[0072] In one embodiment of the present application, multiple main beams 10 and multiple cross beams 12 form a grid frame structure of the main frame, wherein the cross beams 12 are all arranged on the outside of the main beams 10; multiple sliding beams 11 and multiple cross beams 12 form a grid frame structure of the sub-frame, wherein the cross beams 12 are all arranged on the outside of the sliding beams 11.

[0074] A pressure equalizing plate 14 is provided on the inner side of the main frame, and a pressure equalizing plate 14 is provided on the inner side of the sub-frame.

[0075] In one embodiment of the present application, the pressure equalizing plate 14 can not only strengthen the structural strength of the main frame and the sub-frame, but also serve as the basis for the connection of the jacks. One end of the left front jack 5, the left rear jack 7, the right front jack 6 and the right rear jack 8 can be hinged to the pressure equalizing plate 14 of the main frame, and one end of the telescopic jack 13 is hinged to the pressure equalizing plate 14 of the main frame, and the other end is hinged to the jack of the sub-frame, so that the telescopic frame is subjected to more uniform force.

[0077] In this embodiment, the extension direction of the tunnel to be filled is the left-right direction. After the filling is completed and the paste solidifies, the rapid partition device itself forms an independent spatial channel, which is perpendicular to the filling tunnel. The rapid partition device can be withdrawn through the channel and transferred to the next tunnel to be filled. The extension direction of the withdrawal channel is the front-back direction.

[0078] When using the partition device to fill a coal mine tunnel with a large inclination angle, multiple rows of partition devices can be set in the tunnel to be filled; wherein, when one row of partition devices is set, the left front frame 1 and the left rear frame 3 in the partition device face the left of the extension direction of the tunnel to be filled, and the right front frame 2 and the right rear frame 4 face the right of the extension direction of the tunnel to be filled, that is, the tunnel to be filled is divided into two small sections by one row of partition devices; when two rows of partition devices are set, the two rows of partition devices divide the tunnel to be filled into three small sections; then the tunnels divided into small sections by the partition devices are grouting-filled separately. Since the length of each small section of the tunnel is reduced, the height difference of each small section of the tunnel becomes smaller, and the lateral pressure of the slurry on the sealing structure becomes smaller when grouting and filling each section of the tunnel, thereby effectively reducing the risk of slurry filling.

[0079] When the tunnel filling operation is completed and the partition device needs to be removed:

[0080] 1. First, remove the cross brace 9 on the partition device, the clip 25 between the left front bottom plate 17 and the left rear bottom plate 19, and the clip 25 between the right front bottom plate 18 and the right rear bottom plate 20;
