Description

Technical Field

[0001] This invention relates to the field of coal mining support technology, and more particularly to hydraulic supports for temporary roadway support. Background Technology

[0002] Currently, in my country's underground coal mines, roadway support is required during both tunnel excavation and face mining. Traditional techniques primarily employ a combination of anchor bolts / cables and metal / resin mesh for support. Each tunnel cycle (0.8-1.0m) necessitates a row of supports to prevent roof collapses and other safety accidents in the newly exposed roadway. However, the anchor bolt / cable + metal / resin mesh support technology is complex. In mines with challenging conditions, manual support is often necessary, leading to high labor intensity, poor working conditions, low safety, and the inability to reuse anchor bolts / cables and metal / resin mesh, resulting in poor economic efficiency. This significantly restricts tunnel excavation efficiency. Furthermore, because this technology cannot achieve fully enclosed support, it greatly increases the risk of roof collapses and coal face leaks, causing casualties.

[0003] In recent years, related technologies and equipment such as pre-support hydraulic supports and unit hydraulic supports for roadways have developed rapidly. They are used for pre-support or temporary support of roadways and have advantages such as high support efficiency, low labor intensity for workers, high safety factor, and reusability. However, traditional pre-support hydraulic supports and unit hydraulic supports have problems such as complex structure and inability to achieve fully enclosed support. They cannot be used to replace the traditional "anchor bolt / anchor cable + metal mesh / resin mesh" support technology and are difficult to solve the problem of temporary support for coal seam roadways.

Detailed Implementation

[0027] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0028] Hydraulic supports for temporary roadway support according to embodiments of the present invention, such as Figures 1 to 12 As shown, the temporary hydraulic support for the roadway includes a main support frame, a support roof plate, and support side plates. The frame includes support beams and support sleeves, both of which are telescopic. Each support beam has two ends connected to a support sleeve, forming a U-shaped frame. The support roof plate is connected to the support sleeves, and the support side plates are connected to the support beams. Two main support frames are connected, with the support roof plate covering at least a portion of the support beams of both main support frames, and the support side plates covering at least a portion of the support sleeves of both main support frames. The connection of the two main support frames forms a stable support system. The support of the main support frame to the support side plates and support roof plate provides efficient, reliable, and fully enclosed support for the roadway, improving roadway support efficiency and surrounding rock control.

[0029] The hydraulic support for temporary roadway support according to embodiments of the present invention has the advantages of simplified structure and fully enclosed support. The applicant has proposed using a fully enclosed hydraulic support for temporary roadway support, and has invented a hydraulic support for temporary roadway support to replace the traditional "anchor bolt / anchor cable + metal mesh / resin mesh" support technology. Furthermore, it can overcome many shortcomings of advanced hydraulic supports and unitized hydraulic supports, providing technical and equipment support for achieving rapid roadway excavation and efficient, reliable support.

[0030] In some embodiments, such as Figures 5 to 8 As shown, the support beam and support sleeve are hollow structures. The support beam includes a first support column 8, a first support beam 1, and a second support beam 2. The first support column 8 is located inside the support beam, and its two ends are connected to the first support beam 1 and the second support beam 2, respectively. The support sleeve includes a second support column 9, a first support sleeve 3, and a second support base 4. The second support column 9 is located inside the support sleeve, and its two ends are connected to the first support sleeve 3 and the second support base 4, respectively.

[0031] Specifically, both the first support beam 1 and the second support beam 2 are hollow structures. The second support beam 2 is placed inside the first support beam 1. One end of the first support column 8 is connected to the first support beam 1, and the other end of the first support column 8 is connected to the second support beam 2. Through the extension and retraction of the first support column 8, the first support beam 1 and the second support beam 2 can be driven to move relative to each other in the horizontal direction.

[0032] Both the first support sleeve 3 and the second support base 4 are hollow structures. The first support sleeve 3 is placed inside the second support base 4. One end of the second support column 9 is connected to the first support sleeve 3, and the other end of the second support column 9 is connected to the second support base 4. Through the extension and retraction of the second support column 9, the first support sleeve 3 and the second support base 4 can be driven to move relative to each other in the vertical direction.

[0033] The first support sleeve 3 is placed inside the first support beam 1, restricting its movement to an approximately vertical direction. A main support frame is formed by the first support beam 1, the second support beam 2, the first support sleeve 3, the second support base 4, the first support column 8, and the second support column 9. (See attached image) Figure 4 As shown.

[0034] Each temporary hydraulic support for the roadway consists of two main support frames. The first support top plate 5 is fixedly connected to the support sleeves of the two main support frames respectively. The second support top plate 6 is fixedly connected to the other two support sleeves of the two main support frames respectively. The second support column 9 performs telescopic movements, driving the first support top plate 5 and the second support top plate 6 to support the roadway roof.

[0035] In some embodiments, such as Figure 5 and Figure 6As shown, the first supporting crossbeam 1 includes a first directional sleeve 101, a movable limiting plate 102, a first ear plate 103, and a second ear plate 104. The first end of the first directional sleeve 101 is provided with a movable limiting plate 102, and the two movable limiting plates 102 form a first limiting channel. The first ear plate 103 is located inside the first end of the first directional sleeve 101, and the second ear plate 104 is located on the side opposite to the movable limiting plate 102. The second supporting crossbeam 2 includes a crossbeam moving rod 201, an end support cap 202, a third ear plate 203, and a fourth ear plate 204. The first end of the crossbeam moving rod 201 is connected to the end support cap 202. The third ear plate 203 is located inside the first end of the crossbeam moving rod 201, and the fourth ear plate 204 is connected to the end support cap 202. The side of the end support cap 202 away from the crossbeam moving rod 201 is provided with a second limiting channel. The second end of the first directional sleeve 101 is slidably connected to the second end of the crossbeam moving rod 201.

[0036] Specifically, all ear plates are hinged ear plates. The movable limiting plate 102 is fixedly connected to the directional sleeve 101. The two movable limiting plates 102 form a limiting channel, so that the guide support sleeve can only move in the vertical and left-right directions, but cannot move in the front-back direction. The first ear plate 103 is placed inside the directional sleeve 101 and is fixedly connected to the directional sleeve 101. The first ear plate 103 can be used to hinge one end of the first support beam 1 to the first support column 8.

[0037] The second ear plate 104 is fixedly connected to the movable limiting plate 102, and the first supporting beam 1 and one end of the first horizontal beam 12 can be hinged through the second ear plate 104. The movable limiting plate 102 is fixedly connected to the side guard support plate 7.

[0038] The second supporting crossbeam 2 includes a crossbeam moving rod 201, an end support cap 202, a third ear plate 203, and a fourth ear plate 204, see Figure 6 As shown;

[0039] The crossbeam moving rod 201 is fixedly connected to the end support cap 202, and the end support cap 202 makes the support height of the first support crossbeam 1 and the second support crossbeam 2 the same.

[0040] The third ear plate 203 is placed inside the crossbeam moving rod 201 and is fixedly connected to the inside of the crossbeam moving rod 201. The second support crossbeam 2 can be hinged to one end of the first support column 8 through the hinged ear plate.

[0041] The fourth ear plate 204 is fixedly connected to the end support cap 202. The hinged ear plate allows one end of the second support beam 2 to be hinged to the first horizontal beam 12. The end support cap 202 is fixedly connected to the side guard support plate 7.

[0042] In some embodiments, the cross-section of the beam moving rod 201 is smaller than that of the first directional sleeve, and the top of the end support cap 202 is located on the same horizontal plane as the top of the first directional sleeve.

[0043] Specifically, the crossbeam moving rod 201 is fixedly connected to the end support cap 202. The end support cap 202 ensures that the support height of the first support crossbeam 1 and the second support crossbeam 2 is the same, which can ensure the flat overlap of the first support top plate 5 and the second support top plate 6.

[0044] In some embodiments, such as Figure 7 and Figure 8 As shown, the first support sleeve 3 includes a top support cap 301 and a guide rod 302. The top support cap 301 is located at the first end of the guide rod 302 and is connected to the guide rod 302. The top support cap 301 is also connected to the support top plate. A connecting hole is provided on the side of the first end of the guide rod 302. The second support base 4 includes a base body 401, a fifth ear plate 402, a sixth ear plate 403, and a seventh ear plate 404. The fifth ear plate 402 is located on the side of the first end of the base body 401, the sixth ear plate 403 is located on the side of the base body 401, and the seventh ear plate 404 is located inside the second end of the base body 401. The two ends of the second support column 9 are connected to the connecting hole of the guide rod 302 and the base body 401, respectively.

[0045] Specifically, see Figure 7 As shown, the top support cap 301 is fixedly connected to the guide rod 302, and the top support cap 301 is also fixedly connected to the first support top plate 5 or the second support top plate 6. The support column connecting hole 303 is used for hinged connection with the second support column 9. The hinge can be achieved by passing a pin through the support column connecting hole 303 and the second support column 9. The support column can be a hydraulic telescopic column. The support column is used to achieve reciprocating motion in the linear direction.

[0046] The support sleeve base includes a base body 401, a fifth ear plate 402, a sixth ear plate 403, and a seventh ear plate 404;

[0047] The fifth ear plate 402 is fixedly connected to the side wall of the base body 401, and the support sleeve base is connected to one end of the second horizontal beam 13 through the fifth ear plate 402.

[0048] The sixth ear plate 403 is fixedly connected to the side wall of the base body 401, and the support sleeve base is connected to one end of the third horizontal beam 14 through the sixth ear plate 403.

[0049] The seventh ear plate 404 is fixedly connected to the bottom of the base body 401, and the support sleeve base is connected to one end of the second support column 9 through the seventh ear plate 404.

[0050] In some embodiments, such as Figures 9 to 10 As shown, the supporting top plate includes a first supporting top plate 5 and a second supporting top plate 6. Part of the first supporting top plate 5 overlaps with the second supporting top plate 6, and another part of the first supporting top plate 5 and the second supporting top plate 6 are coplanar.

[0051] Specifically, a portion of the first supporting roof plate 5 and the second supporting roof plate 6 overlap and are spliced ​​together to form a complete supporting roof plate. The first supporting roof plate 5 and the second supporting roof plate 6 can be thinned at the joint through cutting, so that the first supporting roof plate 5 and the second supporting roof plate 6 form a flat plane after overlapping, which facilitates the support of the roadway.

[0052] In some embodiments, the first supporting top plate 5 includes a first plate body 501, and the second supporting top plate 6 includes a second plate body 601. The thickness of the half of the first plate body 501 located on the first side is twice that of the half of the second plate body located on the second side, and the thickness of the half of the second plate body 601 located on the first side is twice that of the half of the second plate body located on the second side. The second side of the first plate body 501 overlaps with the second side of the second plate body 601.

[0053] Specifically, half the thickness of the first plate 501 is cut off, and half the thickness of the second plate 601 is also cut off. The first plate 501 and the second plate 601 overlap so that there is no height difference at the overlap, forming a complete plane.

[0054] In some embodiments, such as Figures 9 to 10 As shown, the supporting top plate also includes an eighth ear plate 502 and a ninth ear plate 602. The eighth ear plate 502 is located on the second side of the first plate 501, and the ninth ear plate 602 is located on the first side of the second plate 601.

[0055] Specifically, the eighth ear plate 502 is fixedly connected to the cut side of the first plate 501. The ninth ear plate 602 is fixedly connected to the uncut side of the second plate 601.

[0056] In some embodiments, such as Figure 11 and Figure 12 As shown, the supporting main frame also includes a first horizontal beam 12, a second horizontal beam 13, and a third horizontal beam 14. The first horizontal beam 12, the second horizontal beam 13, and the third horizontal beam 14 connect the two supporting main frames. The two ends of the first horizontal beam 12 are respectively connected to the first supporting beams 1 of the two supporting main frames. The two ends of the second horizontal beam 13 and the two ends of the third horizontal beam 14 are respectively connected to the second supporting bases 4 of the two supporting main frames.

[0057] Specifically, the first horizontal beam 12 and the second horizontal beam 13 have the same structure, including a first supporting beam body 1201, a tenth ear plate 1202, and a first beam body hinge hole 1203; the tenth ear plate 1202 and the side of the first supporting beam body 1201 where the first beam body hinge hole 1203 is arranged are fixedly connected.

[0058] The third horizontal beam 14 includes a second supporting beam 1401, an eleventh ear plate 1402, and a second beam hinge hole 1403.

[0059] The eleventh ear plate 1402 is fixedly connected to the second support beam 1401 through the side of the second beam hinge hole 1403. In order to achieve separate support for the roadway roof and sidewalls, and at the same time improve the stability of the temporary roadway support hydraulic support and the support force for the roof and sidewalls, two first horizontal beams 12, two second horizontal beams 13, and two third horizontal beams 14 are used to connect the two main support frames.

[0060] One end of the first horizontal beam 12 is connected to the first supporting beam 1 of the main supporting frame, and the other end is connected to the first supporting beam 1 of another main supporting frame.

[0061] The two ends of the second horizontal beam 13 and the third horizontal beam 14 are respectively connected to the support sleeve base of the main support frame, and the other end is connected to the support sleeve base of another main support frame.

[0062] In some embodiments, the supporting main frame further includes a third support column 10 and a fourth support column 11. One end of the third support column 10 is connected to the third horizontal beam 14, and the other end is connected to the eighth ear plate 502 or the ninth ear plate 602. One end of the fourth support column 11 is connected to the first horizontal beam 12, and the other end is connected to the second horizontal beam 13.

[0063] Specifically, each temporary hydraulic support for the roadway has two third support columns 10. One end of one third support column 10 is connected to the third horizontal beam 14, and the other end is connected to the first support roof 5. One end of the other third support column 10 is connected to the third horizontal beam 14, and the other end is connected to the second support roof 6.

[0064] The third support column 10 can improve the effective support force of the first and second supporting roof plates 5 and 6 on the roof, and at the same time improve the stability of the temporary hydraulic support for the roadway. Each temporary hydraulic support for the roadway has two fourth support columns 11. One end of each fourth support column 11 is connected to the first horizontal beam 12, and the other end is connected to the second horizontal beam 13. The two fourth support columns 11 can move simultaneously by extending and retracting, which can drive the first supporting beam 1, the second supporting beam 2, the first supporting roof plate 5, the second supporting roof plate 6, the side support plate 7, and the first support column 8 to adjust the support position of the roadway sidewalls.

[0065] The hydraulic temporary support for roadways proposed in this application can effectively support the roadway sidewalls by moving the first support beam 1, the second support beam 2, and the side support plate 7 through the telescopic first support column 8. The telescopic fourth support column 11 can adjust the support position of the roadway sidewalls and support the areas of the roadway most prone to spalling. By simultaneously telescopicating the second support column 9 and the third support column 10, the guide support sleeve, the first support roof plate 5, and the second support roof plate 6 can be driven to support the roadway. The third support column 10 can increase the support force in the middle of the roadway and enhance the control effect of the surrounding rock.

[0066] By retracting the first support column 8, the second support column 9, the third support column 10, and the fourth support column 11, the temporary hydraulic support for the roadway can be retracted, occupying a small volume and facilitating transportation. After the roadway is excavated, the temporary hydraulic support for the roadway is transported to the area to be supported. The extension of the first support column 8, the second support column 9, the third support column 10, and the fourth support column 11 is adjusted according to the cross-sectional dimensions of the roadway, thereby achieving efficient and highly reliable support for the roadway.

[0067] Since the support area of ​​a single temporary hydraulic support for a roadway is limited, the number of temporary hydraulic supports can be increased as the roadway excavation speed gradually increases, thus achieving full-length support for the roadway. During the mining period, the temporary hydraulic supports can be recovered by shrinking the first support column 8, the second support column 9, the third support column 10, and the fourth support column 11, enabling multiple reuses.
