Description

Technical Field

[0001] The utility model relates to the technical field of anchor rods, in particular to an anchor rod for preventing exposure in coal mine tunnels. Background Art

[0002] In coal mine tunnels, in order to prevent the exposure of rocks or coal seams on the tunnel walls or tops, anchor rods are needed for support. Anchor rods are steel bars fixed in the rock mass or coal seams. They are anchored deep in the rock mass to enhance the supporting capacity of the tunnel and prevent rock or coal seam collapse. This support method can effectively improve the stability and safety of the tunnel and ensure the safe operation of miners and equipment.

[0003] After searching, the applicant found that a Chinese patent disclosed "an anchor rod for supporting coal mine tunnels", and its publication (announcement) number is "CN212837882U". This patent mainly increases the support effect and improves safety by setting multiple devices that can fix the support rods in the coal seam, as well as two devices that can fix the metal mesh. However, the anchor rod will be corroded due to long-term exposure to the humid coal mine environment. For this reason, we propose an anchor rod based on coal mine tunnels to prevent exposure.

Drying components 5 are evenly installed on the surface of the support rod 1. The drying components 5 include a first support ring 51, a second support ring 52 and an activated carbon layer 53. The cross-sections of the first support ring 51 and the second support ring 52 are both semicircular, and the inner diameter of the circular ring formed by the first support ring 51 and the second support ring 52 is equal to the diameter of the support rod 1. The activated carbon layer 53 is filled in the cavity of the first support ring 51 and the second support ring 52.

[0024] In this embodiment, through holes 511 are evenly spaced on the surfaces of the first support ring 51 and the second support ring 52, and the bottom surfaces of the first support ring 51 and the second support ring 52 are both mesh-shaped;

[0025] The bottom surfaces of the through holes 511 and the first support ring 51 and the second support ring 52 are all mesh-shaped, which can increase the contact area between the activated carbon layer 53 and the air.

[0026] In this embodiment, both ends of the first support ring 51 are embedded with first magnetic blocks 54, and both ends of the second support ring 52 are embedded with second magnetic blocks 55, and the first magnetic blocks 54 and the second magnetic blocks 55 are magnetically connected;

[0027] The first magnetic block 54 and the second magnetic block 55 are magnetically connected, so that the first support ring 51 and the second support ring 52 can be attracted and fixed on the surface of the support rod 1 by the first magnetic block 54 and the second magnetic block 55, and the first support ring 51 and the second support ring 52 can be easily installed and removed.

[0028] Specifically, by cooperating with the first support ring 51 and the second support ring 52, the first support ring 51 and the second support ring 52 can be fixed on the surface of the support rod 1. At the same time, the activated carbon layer 53 in the cavity of the first support ring 51 and the second support ring 52 will dry the humid air around the support rod 1, thereby preventing the anchor rod from being exposed to the humid coal mine environment for a long time, which may cause corrosion of the anchor rod.

[0029] Example 2, please refer to the attached Figure 1 -Attached Figure 5 An anchor rod for preventing exposure in coal mine tunnels includes a support rod 1 and a support plate 2 fixed to the bottom of the support rod 1. The top surface of the support plate 2 is provided with a mounting groove 3, and a fixing component 4 is installed inside the mounting groove 3. Drying components 5 are evenly installed on the surface of the support rod 1. The drying components 5 include a first support ring 51, a second support ring 52 and an activated carbon layer 53. The cross-sections of the first support ring 51 and the second support ring 52 are both semicircular, and the inner diameter of the circular ring formed by the first support ring 51 and the second support ring 52 is equal to the diameter of the support rod 1. The activated carbon layer 53 is filled in the cavity of the first support ring 51 and the second support ring 52.

[0030] In this embodiment, the fixing assembly 4 includes a fixing nail 41, and crushing balls 411 are evenly installed on the surface of the fixing nail 41, and a through groove 412 is opened on the outer surface of the fixing nail 41;

[0031] The fixing nail 41 is fixed to the ground by a screw gun. The crushing ball 411 will penetrate the annular groove during rotation. Then, adhesive is injected into the annular groove to make the fixing nail 41 adhere to the ground, thereby increasing the stability of the fixing nail 41.

[0032] In this embodiment, the fixing assembly 4 further includes an isolation pad 42 and a fixing ring 43. The isolation pad 42 and the fixing ring 43 are both sleeved on the surface of the fixing nail 41, and the fixing ring 43 is located directly above the isolation pad 42.

[0033] The isolation pad 42 can isolate the adhesive from contacting the fixing ring 43 , thereby preventing the fixing ring 43 from being adhered to the adhesive and becoming difficult to disassemble.

[0034] In this embodiment, two groups of limit blocks 44 are installed on the top surface of the fixing ring 43. The left sides of the two groups of limit blocks 44 are provided with a clamping groove 441. The cross-sectional dimensions of the clamping groove 441 and the through groove 412 are equal. A clamping assembly 45 is installed through the through groove 412.

[0035] The cross-sectional dimensions of the clamping slot 441 and the through slot 412 are equal, so that the clamping assembly 45 can pass through the clamping slot 441 and the through slot 412 .

[0036] In this embodiment, the clamping assembly 45 includes a clamping block 451, a fixed rod 452 and a rotating block 453. The fixed rod 452 is provided with two groups and is fixedly installed at the left and right ends of the clamping block 451 respectively. The rotating block 453 is rotatably connected to the surface of the fixed rod 452. The cross section of the clamping block 451 is a rectangle, and the length of the rectangle is greater than the length of the rotating block 453.

[0037] After the fixing nail 41 and the fixing ring 43 are installed, the clamping block 451 is inserted into the clamping groove 441, and then the rotating block 453 is rotated to a vertical state so that both ends of the clamping block 451 are clamped by the rotating block 453, so that the support plate 2 is fixed to the ground by the fixing nail 41.

[0038] Specifically, by setting the fixing component 4, after inserting the fixing nail 41 into the ground with a screw gun, pouring the adhesive into the ring groove of the crushing ball 411, and then putting the isolation pad 42 and the fixing ring 43 on the surface of the fixing nail 41, the fixing nail 41 can be quickly fixed to the ground, and then the clamping block 451 is passed through the clamping groove 441 and the through groove 412, and the rotating block 453 is rotated to a vertical state, so that the clamping block 451 is clamped in the inside of the clamping groove 441, so as to achieve the effect of quickly fixing the bottom of the support rod 1.

[0039] Working principle:

[0040] First, move the support rod 1 to the position to be supported, and fix the fixing nail 41 to the ground with a screw gun. The crushing ball 411 will penetrate the annular groove during rotation, and then inject adhesive into the annular groove to make the fixing nail 41 bond to the ground, and then put the isolation pad 42 and the fixing ring 43 on the surface of the fixing nail 41, and then insert the clamping block 451 into the inside of the clamping groove 441, and then rotate the rotating block 453 to a vertical state, so that both ends of the clamping block 451 are clamped by the rotating block 453, so that the fixing nail 41 fixes the support plate 2 to the ground through the clamping block 451, and then the first support ring 51 and the second support ring 52 are attracted and fixed to the surface of the support rod 1 by the first magnetic block 54 and the second magnetic block 55, and the activated carbon layer 53 in the cavity of the first magnetic block 54 and the second magnetic block 55 will adsorb and dry the surrounding air, and the entire work process is completed.
