Specific Embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0026] Embodiment 1:

[0027] This embodiment provides a suspension device for the air and water pipelines in the mine, specifically as Figure 1 - Figure 2 shown, including a tensioning bolt 1 for positioning and a suspension assembly 4 installed on the tensioning bolt 1. A plurality of telescopic assemblies 2 for adjusting the length are installed on the suspension assembly 4, and a pressing assembly 3 for limiting the air and water pipelines is installed on the telescopic assembly 2.

[0028] The suspension assembly 4 includes a mounting joint 402 detachably mounted on the tensioning bolt 1. A suspension rod is detachably connected to the mounting joint 402, and the suspension rod is composed of a plurality of suspension rod units 401 detachably connected to each other.

[0029] The telescopic assembly 2 includes a first adjusting rod 202 mounted on the suspension rod unit 401. An adjusting cylinder 201 is detachably connected to the first adjusting rod 202. When needed, the total length of the adjusting cylinder 201 and the first adjusting rod 202 can be adjusted arbitrarily.

[0030] The pressing assembly 3 includes a second adjusting rod 302 detachably mounted on the adjusting cylinder 201. A pressing plate 301 is detachably connected to the second adjusting rod 302, and a second nut 303 for limiting the pressing plate 301 is mounted on the second adjusting rod 302.

[0031] The suspension rod unit 401, the telescopic assembly 2, and the pressing assembly 3 together form a "G"-shaped frame to limit and suspend the water and air pipelines.

[0032] When installing this device, first select appropriate spacing to arrange the drilling positions according to the overall installation height of the water and air pipelines, then determine the number of suspension rod units 401 on the suspension rod according to the number of water and air pipelines, and then adjust the length of the telescopic assembly 2 in a timely manner according to the specifications of the water and air pipelines. The length should be such that the pipelines can be stably placed into the frame exactly. After that, put the tensioning bolt 1 into the drilled hole and lock it, and then install the suspension assembly 4 on the tensioning bolt 1. At this time, adjust the second nut 303 so that the pressing plate 301 presses on the water and air pipelines, and thus the limiting suspension of the water and air pipelines is completed.

[0033] When it needs to be disassembled, first adjust the position of the second nut 303 so that the pressing plate 301 no longer presses down on the water and air pipelines, and then sequentially remove the pressing assembly 3, the water and air pipelines, the telescopic assembly 2, and the suspension assembly 4. Finally, remove the tensioning bolt 1 in the hole as well.

[0034] Among them, the suspension rod unit 401, the first adjusting rod 202, the first adjusting rod 202, and the second adjusting rod 302 can all be obtained by threading used steel pipes; and the pressing plate 301 can be made of used steel plates, I-beams, channel steels, angle steels, etc.

[0035] Through the above settings, the following beneficial effects can be achieved: a. The used steel in the mine can be recycled, reducing solid waste; b. The mine costs and expenses can be greatly saved; c. This device is convenient to install and disassemble and can be reused; and the detachable modular setting enables timely replacement of a damaged component at a certain location instead of scrapping the whole; c. This device is applicable to pipelines of various specifications and has a wide range of uses.

[0036] Embodiment 2:

[0037] This embodiment is further extended on the basis of Embodiment 1, specifically as follows Figure 2 - Figure 3 shown, the suspension rod is threadedly connected to the mounting joint 402, and the suspension rod units 401 are sequentially threadedly connected to form a suspension rod. By means of threaded connection, not only the connection strength at the connection is improved, but also it is convenient for quick disassembly.

[0038] As Figure 2 - Figure 3 shown, the adjusting cylinder 201 is threadedly connected to the first adjusting rod 202. By means of threaded connection, the length can be adjusted arbitrarily, and the length can be fixed automatically by using the self-locking property of the thread.

[0039] As Figure 2 - Figure 3 shown, the second adjusting rod 302 is threadedly connected to the adjusting cylinder 201, a pressing plate 301 is slidably connected to the second adjusting rod 302, and a second nut 303 is threadedly connected to the second adjusting rod 302. By means of threaded connection, the pressing plate 301 is limited, ensuring that the pressing plate 301 will not loosen easily and is also convenient for quick disassembly.

[0040] Embodiment 3:

[0041] This embodiment is further extended on the basis of Embodiment 1 or Embodiment 2, specifically as follows Figure 4 - Figure 5 shown, the tensioning bolt 1 includes a central screw, a screw sleeve, a first nut 103, and a limiting gasket 104. The central screw includes a screw 106 and a first conical block 102, and the first conical block 102 is integrally formed with the screw 106; the screw sleeve includes a second conical block 107 and a first tensioning strip 105, and the second conical block 107 is integrally formed with a plurality of first tensioning strips 105; the limiting gasket 104 is fixedly connected to the second conical block 107, the first nut 103 is threadedly connected to the screw 106, and the first tensioning strip 105 forms a fit with the first conical block 102.

[0042] Insert the central screw and the screw sleeve into the drilled hole, and the limiting gasket 104 is attached to the wall surface. At this time, rotate the first nut 103 so that the screw 106 drives the first conical block 102 to approach the second conical block 107. Since the second conical block 107 cannot move due to the limitation of the limiting gasket 104, the inclined surface of the first conical block 102 expands a plurality of first tensioning strips 105 at this time, so that the first tensioning strips 105 press against the hole wall to prevent the screw 106 from being pulled out of the screw sleeve, realizing a firm installation in the wall.

[0043] As Figure 4 - Figure 5 shown, a plurality of second tensioning strips 101 are provided on the first conical block 102, the second tensioning strips 101 are arranged alternately with the first tensioning strips 105, and the second tensioning strips 101 form a fit with the second conical block 107.

[0044] While the first tensioning strip 105 expands, the second tensioning strip 101 is also expanded by the inclined surface of the second conical block 107, further strengthening the fastening effect.

[0045] As Figure 4 - Figure 6 shown, barbs 108 are provided at one end of the first tensioning strip 105 away from the second conical block 107 and one end of the second tensioning strip 101 away from the first conical block 102. The cross-section of the barb 108 is an obtuse triangle, and the obtuse angle opens towards the first conical block 102. The obtuse angle plus α is 180 degrees. The barbs 108 are integrally formed with the second tensioning strip 101 and the first tensioning strip 105 respectively.

[0046] When the first tensioning strip 105 and the second tensioning strip 101 both expand and press against the hole wall, since the moving directions of the second tensioning strip 101 and the first tensioning strip 105 are away from the hole, the barbs 108 can be embedded in the hole wall to prevent the second tensioning strip 101 and the first tensioning strip 105 from moving, further strengthening the fastening effect.

[0047] As Figure 4 shown, the hanging assembly 4 further includes a third nut 403. The third nut 403 is threadedly connected to the tensioning bolt 10, and the third nut 403 cooperates with the first nut 103 to fix the mounting joint 402.

[0048] By rotating the third nut 403 on the screw rod 106, the mounting joint 402 is pressed against the first nut 103 by the third nut 403, realizing the fixation of the mounting joint 402, and the installation and disassembly are convenient and fast.

[0049] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention falls within the protection scope of the present invention.
