Description

Technical Field

[0001] This utility model relates to the field of grouting reinforcement technology, specifically a grouting reinforcement device for the inner wall of a tunnel. Background Technology

[0002] Roadways are various passages drilled between the surface and the ore body, used for ore transportation, ventilation, drainage, pedestrian access, and various necessary preparatory works for new ore extraction by metallurgical equipment. These passages are collectively called roadways. To ensure the safety of coal mining, grouting is generally carried out on the sidewalls of the roadways to reinforce them.

[0003] In the prior art, the authorized announcement number CN219865037U describes a grouting reinforcement device for the inner wall of a roadway, which relates to the field of grouting reinforcement technology. It includes a base, a fixed cylinder installed on the top of the base, and a first lifting cylinder, a pushing block, and an adjusting rod arranged sequentially from bottom to top inside the fixed cylinder. The first lifting cylinder drives the pushing block to move the adjusting rod up and down inside the fixed cylinder. First support components are provided on the left and right sides of the fixed cylinder, and a second support component is provided above the first support components. The first support components are used to support the side plates on both sides of the inner wall of the roadway, and the second support components are adjusted and supported by the adjusting rod. A third support component is provided on the top of the adjusting rod.

[0004] Currently, grouting in tunnels requires the use of support devices for reinforcement. These support devices are assembled manually into a support frame that meets the support requirements. This support frame requires drive equipment such as cylinders and motors for adjustment, which limits its electrical compatibility, reduces the applicable environment for the tunnel wall grouting reinforcement device, and increases the cost of using the tunnel wall grouting reinforcement device.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figure 1 - Figure 4As shown, this utility model provides a technical solution for a roadway inner wall spraying grouting reinforcement device, including two base plates 1, with threaded rods 2 fixedly connected to the upper part of the base plates 1, and a linear array of connecting components 3 arranged between the two threaded rods 2. A linear array of support components 4 is arranged on the threaded rods 2, and the support components 4 include two first slip rings 401 slidably sleeved on the threaded rods 2. A first threaded ring 402 is rotatably connected to the upper part of the first slip ring 401, and the first threaded ring 402 is threadedly sleeved on the outside of the threaded rod 2. An inclined rod 403 and a support rod 404 are rotatably connected to one side of each of the two first slip rings 401. The movable end of the inclined rod 403 is rotatably connected to the side wall of the support rod 404. A top support component 6 is arranged at the top of the threaded rod 2. The inclined rods 403 and the support rods 404 in the same group are arranged in a V-shape.

[0024] Specifically, by rotating the first threaded ring 402 on the inclined rod 403, the two first threaded rings 402 in the same group are adjusted to move closer or further apart. The inclined rod 403 then drives the support rod 404 to move, and the end of the support rod 404 supports the sidewall inside the tunnel.

[0025] like Figure 1 and Figure 2 As shown, the connecting assembly 3 includes a bidirectional screw 303 and two second slip rings 301. A second threaded ring 302 is rotatably connected to the upper part of the second slip ring 301. Two connecting plates 304 are symmetrically arranged and threaded on the outer side of the bidirectional screw 303. The two second slip rings 301 are rotatably connected to both sides of the connecting plates 304 and connecting rods 305. The four connecting rods 305 are arranged in an equilateral quadrilateral. The second threaded ring 302 is threaded on the outer side of the threaded rod 2. Two external threads are symmetrically arranged on the outer side of the bidirectional screw 303. The two connecting plates 304 are threaded on the two external threads in the bidirectional screw 303.

[0026] Specifically, by rotating the bidirectional screw 303, the bidirectional screw 303 drives the two connecting plates 304 to move away from or closer to each other, and by using the cooperation of each connecting rod 305, the two threaded rods 2 are brought closer to or further away from each other. This makes it convenient for the grouting reinforcement device for the inner wall of the tunnel to be adjusted according to the width of the tunnel.

[0027] like Figure 1 As shown, a vertical rod 7 is fixedly connected to the upper part of the base plate 1. The first slip ring 401 and the second slip ring 301 each have two through-type sliding holes on their upper parts. The first slip ring 401 and the second slip ring 301 are slidably sleeved on the outside of the vertical rod 7 and the outside of the threaded rod 2 through the two sliding holes. The vertical rod 7 and the threaded rod 2 are arranged parallel to each other.

[0028] Specifically, the vertical rod 7 is used to improve the stability of the first slip ring 401 and the second slip ring 301, and to ensure that the first slip ring 401 and the second slip ring 301 can only move up and down on the threaded rod 2, and cannot rotate on their own.

[0029] The threaded rod 2 and the bidirectional screw 303 are common screws that can be covered by a dustproof and metal particle-proof cover, or can be replaced and cleaned regularly. There are no specific time or frequency restrictions on their use. During use, an anti-corrosion coating or paint can be sprayed on the entire device to increase the dustproof and anti-corrosion effect of the threaded rod 2 and the bidirectional screw 303. Since this structure is an existing technology structure, its maintenance and upkeep methods, as well as its dustproof and anti-corrosion issues, will not be described in detail in this application.

[0030] like Figure 1 and Figure 4 As shown, the top support assembly 6 includes a threaded tube 601, a rotating plate 602 is rotatably connected to the top of the threaded tube 601, and a contact plate 8 is rotatably connected to the top of the rotating plate 602 and the movable end of the support rod 404.

[0031] The contact plate 8 is used to contact and abut against the inner wall of the tunnel.

[0032] like Figure 1 and Figure 4 As shown, the outer sides of the first threaded ring 402, the second threaded ring 302, and the threaded tube 601 are all fixedly connected with pull rods 5 arranged in a circumferential array.

[0033] The pull rod 5 facilitates the rotation of the first threaded ring 402 or the second threaded ring 302.

[0034] like Figure 1 and Figure 3 As shown, a first bevel gear 10 is fixedly provided on one side of the first slip ring 401 and on the outer side of the first threaded ring 402. The two first bevel gears 10 are meshed with each other. A first rocker plate 9 is fixedly connected at the axis of the first bevel gear 10 on the first slip ring 401. The two first bevel gears 10 in the same group are arranged perpendicular to each other.

[0035] By rotating the first rocker plate 9, the first rocker plate 9 drives the first threaded ring 402 to rotate using the first bevel gear 10, thus facilitating the adjustment of the height of the first slip ring 401.

[0036] like Figure 1 and Figure 2 As shown, a second bevel gear 12 is fixedly provided on one side of the second slip ring 301 and the outer side of the second threaded ring 302. The two second bevel gears 12 are meshed with each other. A second rocker plate 11 is fixedly connected at the axis of the second bevel gear 12 on the second slip ring 301. The two second bevel gears 12 in the same group are arranged perpendicular to each other.

[0037] By rotating the second rocker plate 11, the second rocker plate 11 drives the second threaded ring 302 to rotate using the second bevel gear 12, thus facilitating the adjustment of the height of the second slip ring 301.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
