AI Technical Summary
The existing support structure of the coal mine with a maximum inclination angle of 61° in the large-angle working face has unreasonable stress problems under extreme working conditions, especially the unreasonable stress of the sleeve, which cannot maintain the rationality of the stress of the structural parts under the two-way extreme large inclination state.
A two-way through design of four sleeves is adopted. The first and third sets of sleeves are inserted from top to bottom, and the second and fourth sets of sleeves are inserted from bottom to top. A blind hole support structure with a plate is used on the end face of each sleeve to transmit force to other parts of the structural parts through the blind hole plate support.
Under large inclination angles, the sleeve structure has extremely stable supporting capabilities, which can effectively transmit lateral forces and ensure the stability of the structural parts.

Abstract
Description
Technical Field
[0001] The present invention relates to the field of coal mine machinery, in particular to a steeply inclined support sleeve structure. Background Art
[0002] The maximum inclination angle of a coal mine's high-angle working face reaches 61°, requiring the use of special high-angle supports to meet production needs. This set of supports has an extremely unreasonable stress structure under extreme working conditions. To ensure that the structural components are reasonably stressed when meeting the two-way extreme high-angle conditions, the top beam and cover beam of the structure adopt a two-way four-jack support structure. In addition, to ensure that the sleeve is reasonably stressed when the two-way jack is locked with the pin shaft, a blind hole support form is adopted.
[0003] In the past, when the support structure was under stress, the top plate was the main support. The sleeve adopts a two-way through structure, so the direction of each sleeve is consistent, and there is no need to consider the extreme stress conditions when going up and down the mountain.
[0004] Therefore, it is necessary to provide a steeply inclined bracket sleeve structure to solve the above technical problems. Summary of the Invention
[0005] The present invention provides a steeply inclined bracket sleeve structure, which solves the problems in the background technology.
[0006] In order to solve the above technical problems, the steeply inclined bracket sleeve structure provided by the present invention includes: a side plate, two first blind hole type plates, two second blind hole type plates, and four jacks;
[0007] The two first blind hole plates and the two second blind hole plates are both installed on the side panels, and blind holes are provided on the two first blind hole plates and the two second blind hole plates. The first and third sets of sleeves are inserted into the two first blind hole plates from top to bottom, and the second and fourth sleeves are inserted into the two second blind hole plates from bottom to top. The bottoms of the four jacks are respectively fixed on the four sets of sleeves and the lower parts of the two first blind hole plates and the two second blind hole plates.
[0008] Preferably, the two first blind hole type boards and the two second blind hole type boards are both provided with through holes and blind hole support points.
[0009] Preferably, the through holes of the two first blind hole type boards are located at the upper part, and the blind hole support points of the two first blind hole type boards are located at the lower part.
[0010] Preferably, the through holes of the two second blind hole type boards are located at the bottom, and the blind hole support points of the two second blind hole type boards are located at the top.
[0011] Compared with the related art, the steeply inclined bracket sleeve structure provided by the present invention has the following beneficial effects:
[0012] The present invention provides a steeply inclined bracket sleeve structure. The sleeve utilizes four sleeves that intersect in both directions. The first and third sleeve groups are inserted from top to bottom, while the second and fourth sleeves are inserted from bottom to top. Each sleeve end face utilizes a blind hole support structure with a plate. This sleeve structure is designed to expand laterally in both directions at large inclination angles, providing an extremely stable support structure when subjected to large lateral forces. The force applied to the side panels is transmitted to the support jacks, then to the sleeves, and ultimately supported by the blind hole plate, effectively transmitting the force to other parts of the structural component.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0018] Please refer to Figure 1 、 Figure 2 ,in, Figure 1 A structural schematic diagram of a preferred embodiment of the steeply inclined bracket sleeve structure provided by the present invention; Figure 2 This is a schematic diagram of the first blind hole type board structure provided by the present invention; Figure 3 Schematic diagram of the second blind hole plate structure provided by the present invention. The steeply inclined bracket sleeve structure includes: a side plate 1, two first blind hole plates 2, two second blind hole plates 3, and four jacks 4;
[0019] The two first blind hole plates 2 and the two second blind hole plates 3 are both installed on the side panel 1, and the two first blind hole plates 2 and the two second blind hole plates 3 are both provided with blind holes 5, and the first and third sets of sleeves are inserted into the two first blind hole plates 2 from top to bottom, and the second and fourth sleeves are inserted into the two second blind hole plates 3 from bottom to top, and the bottoms of the four jacks 4 are respectively fixed to the four sets of sleeves and the lower parts of the two first blind hole plates 2 and the two second blind hole plates 3.
[0020] The first blind hole type patch plate 2 and the two second blind hole type patches 3 are both provided with through holes 6 and blind hole support points 7. The through holes 6 are used for inserting the sleeve, and the blind hole support points 7 can support the sleeve.
[0021] The through hole 6 of the first blind hole plate 2 is located at the upper part, the two blind hole support points 7 of the first blind hole plate 2 are located at the lower part, and the first and third sets of sleeves are inserted from top to bottom.
[0022] The through hole 6 of the second blind hole plate 3 is located at the bottom, the two blind hole support points 7 of the second blind hole plate 3 are located at the top, and the second and fourth sleeves are inserted from bottom to top.
[0023] The working principle of the steeply inclined bracket sleeve structure provided by the present invention is as follows:
[0024] The bidirectional through-sleeve structure overcomes the upper pressure with the first and third sleeves, and the bottoms of two jacks 4 are fixed to the sleeve and the lower portion of the first blind hole plate 2. The second and fourth sleeves overcome the lower pressure with the bottoms of two jacks 4 fixed to the sleeve and the lower portion of the second blind hole plate 3. The sleeve utilizes a single-sided blind hole 5, which ensures excellent manufacturability during structural fabrication. During the sleeve welding process, the four main reinforcements are first grouped together to ensure the main reinforcement welds are welded, and then the entire sleeve is threaded through the four sleeves.
[0025] Compared with the related art, the steeply inclined bracket sleeve structure provided by the present invention has the following beneficial effects:
[0026] The sleeves are four-piece, interlaced in both directions. The first and third sets of sleeves are inserted from top to bottom, while the second and fourth sets are inserted from bottom to top. Each sleeve end features a blind hole support structure. This sleeve design allows for bidirectional lateral expansion at high inclination angles, providing an extremely stable support structure under high lateral forces. Forces from the side panel 1 are transmitted to the support jacks 4, then to the sleeves, ultimately supported by the blind hole support plates, effectively transmitting them to other parts of the structure.

Any equivalent structure or equivalent process transformation made using the contents of the present invention description and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
