Description

Technical Field

[0001] The utility model relates to the technical field of mine support safety, in particular to a mine arc steel belt device. Background Art

[0002] At present, the roof support of coal mines generally uses ordinary steel belts and mesh anchors to fix the steel belts on the roof of coal mines. However, since the shape of ordinary steel belts does not match that of the roof, there are various gaps between the steel belts and the roof, which can easily cause coal blocks to fall from the gaps and affect the safety of the construction workers below the steel belts. Therefore, it is necessary to rely on arc-shaped steel belts to minimize the gap between the steel belts and the roof of coal mines to reduce safety hazards. However, in the actual construction process, there are still gaps and other reasons, which cause some coal blocks to fall. Therefore, in addition to improving the shape of the steel belts themselves to fit the roof of coal mines, it is also necessary to increase protective facilities to improve the safety of the construction workers below.

[0032] When in use, the mesh anchor is passed through the anchor hole 101 to fit the steel belt body 1 to the coal mine roof, and then the leak-proof plate 2 is hoisted on the inner side of the steel belt body 1 by the connector 3, and is located above the main construction activity area of ​​the workers, playing a secondary protection role. The connector 3 and the mounting portion 102 can be detachably connected in a plug-in connection, a bolt connection or the like, and the mounting portion 102 can be an integral structure with the steel belt body 1, or can be fixed to the steel belt body 1 by welding or the like.

[0033] The connecting member 3 can be one, for example, the leak-proof plate 2 is tilted, the lower end of the connecting member 3 is fixedly connected to the middle or upper part of the leak-proof plate 2, and the upper end of the connecting member 3 is connected to the mounting portion 102, so that the leak-proof plate 2 is hoisted above the construction area. The connecting member 3 can also be several, so as to improve the installation and connection stability of the leak-proof plate 2.

[0034] The width of the arc-shaped steel belt body 1 is in the axial direction, and the leakage-proof plate 2 is wider than the steel belt body 1 in the axial direction, which can better block falling objects.

[0035] The steel belt body 1 is arc-shaped, and a "V"-shaped reinforcement structure can be provided on both sides of the width direction. Anchor holes 101 are distributed in an array on the steel belt body along the circumferential direction.

[0036] Furthermore, one end of the connector 3 is plug-connected to the mounting portion 102 , and the other end is fixedly connected to the leakage-proof plate 2 .

[0037] When in use, the leak-proof plate 2 is detachably connected to the steel belt body 1 through the connector 3, which is convenient for disassembly, assembly and relocation operations. The upper end of the connector 3 can be plug-connected with the mounting portion 102, and the lower end can be fixedly connected with the leak-proof plate 2 for hoisting. The plug-in connection structure can be a rail-type sliding plug-in connection.

[0038] Furthermore, there are several connectors 3 , each of which has an upper connector 301 and a lower connector 302 . The upper connector 301 is plug-connected to the mounting portion 102 , and the lower connector 302 has a slot 3021 , and the side of the leak-proof plate 2 is plug-connected to the slot 3021 .

[0039] When in use, the leak-proof plate 2 is detachably connected to the steel belt body 1 through the connector 3, the upper connecting portion 301 is detachably plugged with the mounting portion 102, and the lower connecting portion 302 is detachably plugged with the leak-proof plate 2 through the slot 3021, which makes disassembly and assembly more convenient, and it is convenient to install multiple connectors 3 on one side of the leak-proof plate 2, and hoist it on multiple steel belt bodies 1 at the same time to improve stability. The connectors 3 can be hoisted and set on both the upper and lower sides of the leak-proof plate 2 to more stably catch the fallen coal. It is more convenient to select leak-proof plates 2 of different areas for installation according to the size of the construction area, and it has strong adaptability and is easy to replace.

[0040] The upper connecting portion 301 and the lower connecting portion 302 are respectively located at the upper and lower sides of the connecting member 3 .

[0041] Furthermore, the lower connection portion 302 has a threaded hole 3022 , which is connected to the slot 3021 , and further includes: a fastening bolt 4 which is threadedly connected to the threaded hole 3022 , and one end of the fastening bolt 4 is used to abut against the anti-leakage plate 2 .

[0042] When in use, the lower connection part 302 is plugged and connected to the side of the leakage-proof plate 2 through the slot 3021 , and the fastening bolts 4 are provided to tighten the leakage-proof plate 2 to improve the connection stability.

[0043] Furthermore, the upper connecting portion 301 is a “T”-shaped structure, the mounting portion 102 is a hanging rail 1021 , and a “T”-shaped slide groove 1022 is provided in the middle of the hanging rail 1021 , and the mounting portion 102 is plugged into and matched with the slide groove 1022 .

[0044] When in use, the upper connecting portion 301 is a "T"-shaped structure, which cooperates with the hanging rail 1021 to facilitate the hanging of the leak-proof plate 2. The hanging rail 1021 has a slide groove 1022. The hanging rail 1021 can be composed of two symmetrically arranged "∟"-shaped plates, which are arranged at intervals to form a "T"-shaped slide groove 1022. The "∟"-shaped plates can be welded or stamped inside the steel body.

[0045] The upper connecting portion 301 is inserted into the sliding groove 1022 from the side.

[0046] Furthermore, the slide groove 1022 penetrates the steel belt body 1 along the radial direction of the steel belt body 1 .

[0047] When in use, the slide groove 1022 penetrates the steel strip body 1, that is, the "∟" type plate hanging rail 1021 can be stamped and formed by the middle of the steel strip body 1, which is simpler to manufacture. Select an area, use a knife or cutting equipment to process a broken line on the steel strip body 1, and then stamp it to form two symmetrically arranged "∟" type plates.

[0048] Furthermore, the leakage-proof plate 2 is a steel plate or a filter screen.

[0049] When in use, when the leak-proof plate 2 is a filter screen, the mesh density should be large enough to intercept the coal blocks falling from above. The falling coal blocks are blocked on the filter screen, slowing down the sliding speed, and finally sliding down along the inclined leak-proof plate 2 to the non-construction area. There are fewer coal blocks remaining on the leak-proof plate 2, and the weight accumulation will not cause the leak-proof plate 2 to fall.

[0050] Furthermore, a side of the leakage-proof plate 2 opposite to the steel strip body 1 has a reinforcing rib 201 .

[0051] When in use, the reinforcement ribs 201 can improve the support strength of the anti-leakage plate 2 and can also slow down the falling speed of the coal blocks. The reinforcement ribs 201 can be distributed in a grid shape.

[0052] Furthermore, both ends of the steel strip body 1 in the circumferential direction have a locking groove 103 .

[0053] When in use, the steel belt body 1 is generally fixed by a mesh anchor rod, and sometimes a support plate is also needed to provide vertical support at the bottom. The two ends of the steel belt body 1 are provided with a clamping groove 103, which is convenient for plugging and docking with other support plates, and can better achieve stable support. The clamping groove 103 can also be stamped, and the end side of the steel belt body 1 is stamped inward to form a "∟"-shaped structure, and the clamping groove 103 is formed between the "∟"-shaped structure and the main body of the steel belt body 1.

[0054] Furthermore, the mounting portions 102 are arranged in an array at equal angles and intervals on the steel belt body 1 .

[0055] When in use, the mounting parts 102 are arranged at equal angles, and one mounting part 102 can be arranged between every two adjacent anchor holes 101, so that the leakage-proof plate 2 can be installed at different angles in the circumferential direction to protect the leakage-prone position of the coal block. The equal angle interval arrangement makes installation and matching more convenient.
