Description

Technical Field

[0001] The utility model relates to the technical field of exploration hole auxiliary charging tools, in particular to a goaf area exploration hole auxiliary charging tool. Background Art

[0002] Goaf exploration holes are typically drilled in mines or other underground projects to survey areas that have been mined or are about to be mined. Because the small wells within the fire zone were mined long ago, the specific distribution of the goaf is still unclear. Therefore, prior to fire control, goaf exploration is necessary to assess the spatial distribution and stability of the goaf, as well as potential safety hazards such as collapse and water seepage.

[0003] At present, before the fire area is controlled, advance exploration of the goaf must be carried out first. The exploration holes are arranged in an area of ​​5mx5m, and the exploration holes are relatively dense. It would be a pity if the exploration holes were abandoned. For this reason, an auxiliary charging tool is designed. It is placed in a certain position in the exploration hole to block the bottom of the exploration hole, and then explosives are loaded in the hole. It is detonated together with the designed drill hole, which can reduce the drilling cost and achieve better economic benefits. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose an auxiliary charging tool for exploration holes in goaf areas, which can be extended into the exploration holes and seal the exploration holes to facilitate subsequent charging and blasting.

[0011] Furthermore, the anti-slip component also includes a U-shaped pad provided on the inner side of the soft limit frame, and the upper and lower ends of the outer side of the U-shaped pad are fixedly connected with anti-slip nails, and the outer ends of the anti-slip nails pass through the window.

[0012] Furthermore, an elastic band is fixedly connected between two adjacent U-shaped pads, and a Velcro is fixedly connected to the middle of the elastic band on the front side.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Reference Figure 1 - Figure 2 The utility model provides an embodiment of a goaf exploration hole auxiliary charging tool, comprising a gas generator 1, a gas bag 2 for inflating and blocking the exploration hole is installed at the bottom of the gas generator 1, a pull ring 4 is installed on the upper side of the gas generator 1, and a traction rope 3 is fixedly connected to the outside of the pull ring 4 for placing the gas generator 1 and the gas bag 2 into the exploration hole, and a connecting ring 5 is fixedly connected to the top of the traction rope 3. A plurality of scale rings 6 are provided on the outside of the traction rope 3 for controlling the depth of the exploration hole, a first buckle 7 is fixedly connected to the left side of the top of the gas generator 1, and an opening 8 is provided at the end of the first buckle 7, a rotating block 9 is fixedly connected to the right side of the top of the gas generator 1, and a second buckle 10 is rotatably connected to the outside of the rotating block 9, and an embedded fast 11 is provided at the end of the second buckle 10, and a protrusion 12 is provided on the front and rear sides of the embedded fast 11. The outer wall of the embedded fast 11 is tightly fitted with the inner wall of the opening 8, and the pull ring 4 is sleeved on the outside of the first buckle 7 and the second buckle 10.

[0024] The gas generator 1 and the airbag 2 are placed in the exploration hole through the provided traction rope 3. The outer side of the scale ring 6 provided on the outside of the traction rope 3 is provided with a scale. By observing the scale, the depth of the gas generator 1 and the airbag 2 extending into the exploration hole is controlled. The provided gas generator 1 is provided with a wireless device, which can be remotely controlled from the ground to control the gas generator 1 to generate gas. The gas fills the airbag 2 through the air hole provided at the bottom, so that the airbag 2 expands and props up, thereby clinging to the inner wall of the exploration hole, thereby blocking the exploration hole, making it convenient to subsequently charge the inside of the exploration hole for blasting. The second buckle provided 10 can be rotated by the rotating block 9, and the rotating second buckle 10 embeds the embedding block 11 set at the end into the opening 8, and the set protrusion 12 makes the embedding block 11 embed into the opening 8. When the second buckle 10 is subjected to a large force, the second buckle 10 will rotate, and the embedding block 11 will be separated from the opening 8. After the gas generator 1 and the airbag 2 are installed in the appropriate position, the traction rope 3 is pulled hard to rotate the second buckle 10, so that the pull ring 4 is separated from the first buckle 7 and the second buckle 10, which makes it convenient to retract the traction rope 3 and facilitate subsequent charging.

[0025] Reference Figure 1 、 Figure 3 and Figure 4The airbag 2 is fixedly connected to the outside with multiple soft limit frames 13, and a window 14 is opened in the middle of the soft limit frame 13. A U-shaped pad 15 is provided on the inside of the soft limit frame 13. The upper and lower ends of the outer side of the U-shaped pad 15 are fixedly connected with anti-slip nails 16. The outer ends of the anti-slip nails 16 pass through the window 14. An elastic band 17 is fixedly connected between two adjacent U-shaped pads 15, and a Velcro 18 is fixedly connected to the middle of the front elastic band 17.

[0026] The set soft limit frame 13 is made of soft rubber material, and the set U-shaped pad 15 and anti-slip nail 16 can be detached from the soft limit frame 13, which is convenient for disassembly and replacement of the U-shaped pad 15 and anti-slip nail 16. The set elastic belt 17 can pull multiple U-shaped pads 15 and anti-slip nails 16 together when the airbag 2 is inflated, reduce the volume, and facilitate insertion into the exploration hole. When the set airbag 2 is inflated, it drives the U-shaped pad 15 and anti-slip nail 16 to move, contact the inner wall of the exploration hole, and insert the anti-slip nail 16 into the inner wall of the exploration hole, thereby preventing the gas generator 1 and the airbag 2 from moving after being fixed.

[0027] Working principle: The gas generator 1 and the airbag 2 are placed in the exploration hole through the provided traction rope 3, and the depth of the insertion into the exploration hole is controlled by the provided traction rope 3 and the scale ring 6. After reaching the appropriate depth, the gas generator 1 is started by remote control to generate gas. The gas fills the gas generator 1, causing it to expand, driving the external soft limit frame 13, U-shaped pad 15 and anti-slip nail 16 to move, so that they contact the inner wall of the exploration hole. The provided anti-slip nail 16 passes through the window 14 and is inserted into the inner wall of the exploration hole, so that the gas generator 1 and the airbag 2 are fixed inside the exploration hole. By pulling the traction rope 3 vigorously, the second buckle 10 is rotated, and the embedded block 11 is separated from the opening 8, so that the pull ring 4 is separated from the first buckle 7 and the second buckle 10, and the traction rope 3 is retracted, which is convenient for subsequent charging into the exploration hole for blasting.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
