[0002] At present, the commonly used method for hydraulic fracturing in mines is to install a hydraulic fracturing sealer on a special grouting drill pipe after drilling with a hydraulic drill rig, and use the hydraulic drill rig and special grouting drill pipe to push the hydraulic fracturing sealer into the borehole. After the hydraulic fracturing sealer reaches the specified depth, hydraulic fracturing is carried out. After the hydraulic fracturing is completed, the special grouting drill pipe is pulled out of the borehole using the hydraulic drill rig, and then the hydraulic fracturing sealer is removed.

[0003] The existing hydraulic fracturing method has the following disadvantages: when using a drilling rig with a special grouting drill rod to push the hydraulic fracturing sealer into the borehole and pull it out of the borehole, workers need to carry the special grouting drill rods one by one to the bottom of the drilling rig for installation, and then remove the special grouting drill rods one by one after the construction is completed. The construction efficiency is low, the labor intensity is high, and the labor cost is high. In addition, the frequent handling of drill rods by workers is dangerous and poses a safety hazard. In addition, the drilling rig requires frequent maintenance, and the failure rate is high, which affects the work progress.

[0004] In view of the above-mentioned deficiencies, the present application proposes a device for delivering a hole sealer through a pneumatic anchor drill. Utility Model Content

The hollow pneumatic chuck 5 is a conventional equipment in the mechanical field. This application is only used and no improvement is made, so its specific structure and working principle are not described in detail.

[0036] Reference Figure 1 and Figure 2 The sleeve four 6 can be rotated 360 degrees and is connected to the vertical sleeve body, and a sleeve bolt 15 is provided on the sleeve four 6.

[0037] Reference Figure 1 and Figure 4 The triangular support frame includes a triangular top seat 16 located outside the jack 1 and a triangular support clamp 7 installed above the triangular top seat 16. The triangular positions on the outside of the triangular top seat 16 are movably connected to the triangular support legs 10, and the bottom of the triangular top seat 16 is provided with a triangular support body 9. The top of the triangular support leg 10 is movably connected to the triangular top seat 16 through a double-headed cylindrical pin 12. The middle part of the triangular support leg 10 is a hollowed-out groove, in which the triangular support legs 11 are movably connected. The three triangular support legs 11 are connected to the triangular support base 13. The triangular support base 13 is located directly below the triangular top seat 16 and is slidably connected to the outside of the triangular support body 9.

[0038] The special feature of this method is that it can utilize the existing anchor drilling rig in the mine to push the specially made hollow steel pipe 20 connected with the hole sealer to the fracturing position through the drilling rig to implement hydraulic fracturing;

[0039] It should be noted that the hollow steel pipe 20 is a special hydraulic fracturing hollow steel pipe. Unlike traditional drill pipe, it is hollow inside, about 1.5 meters long, 25 mm in diameter, with a male end and a female end. The connecting diameter at both ends is about 36 mm, and it weighs about 2.5 kg. Two hollow steel pipes 20 can be connected end to end. The special hydraulic fracturing hollow steel pipe 20 can be connected to the hole sealer and pneumatic anchor drill rig 19 through a sleeve. Truly simple and reliable operation, it can replace the current hydraulic drilling rig, reduce the number of operators, and only two employees are needed to complete the operation, greatly reducing the difficulty and cost of construction.

[0040] The specific operating principles of this application are as follows:

[0041] The hydraulic fracturing continuous conveying device includes the following steps:

[0042] Step 1: First, place the retractable support body under the drill hole to be fractured, adjust the position of the sleeve four 6 to facilitate the installation of the hollow steel pipe 20; then manually send the sealer into the drill hole of the mine roof, and then pass a section of the hollow steel pipe 20 through the pneumatic chuck 5 and the sleeve four 6 and connect it to the sealer through threads. At the work site, the compressed air pipeline is connected to the pneumatic anchor drill rig 19 respectively, and preparations for transportation are made.

[0043] Step 2: Adjust the jack 1 and the tripod support frame to ensure that the support body cannot fall over when transporting the hollow steel pipe. Adjust the jack lifting handle 8 to adjust the jack 1. The jack lifting handle 8 is located on one side of the jack 1. The tripod support clamp 7, the tripod support body support 9, the tripod support outer support leg 10, the tripod support inner support leg 11, the double-headed cylindrical pin 12, and the tripod support base 13 together constitute the tripod support structure.

[0044] The triangular bracket clamp 7 fits over the bottom of the jack 1 and is secured with bolts. The outer triangular support leg 10 is hollowed out in the middle, with a pair of circular holes in the inner sidewalls and rounded corners at the top. These holes are coaxially connected to the holes, and a double-ended cylindrical pin 12 passes through the middle, allowing the outer triangular support leg 10 to rotate about its axis. This same coaxial rotational connection is also applied to the connection between the inner triangular support leg 11 and the outer triangular support leg 10, increasing the leg's flexibility. The outer triangular support leg 10 can be adjusted via the triangular support base 13. This adjustment prevents the main support from tipping over.

[0045] Step three, after adjusting the pillar body, the locking function is realized by the hollow pneumatic chuck 5 on the sleeve four 6. The sleeve four 6 can provide a support point for the hollow steel pipe 20, so that the hollow steel pipe 20 and the drilling hole, the sleeve four 6 and the pneumatic anchor drill 19 have three support points; the hollow pneumatic chuck 5 is used to fix the hollow steel pipe 20 passing through the sleeve four 6, and the hollow pneumatic chuck 5 can prevent the hollow steel pipe from slipping when connecting the next section of the hollow steel pipe 20.

[0046] Step 4: After connecting the next section of the hollow steel pipe 20, push the hollow steel pipe 20 and the hole sealer into the drill hole through the pneumatic anchor drill 19, and then adjust the tightening degree of the pneumatic chuck 5 through the pneumatic chuck air inlet and outlet 14. After the pneumatic chuck 5 has stably fixed the hollow steel pipe 20, the threads between the hollow steel pipes 20 are connected, and the next section of the hollow steel pipe 20 is connected to the previous fixed hollow steel pipe, and then the hollow steel pipe 20 is transported by the pneumatic anchor drill 19.

[0047] By the above reciprocating conveying of the hollow steel pipe, the hollow steel pipe 20 with the hole sealer is advanced to a specified depth in the borehole, thereby completing hydraulic fracturing.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents.
