Description

Technical Field

[0001] The utility model relates to the technical field of mine mining, in particular to a mining engineering mine blasting device. Background Art

[0002] Mines include coal mines, metal mines, non-metallic mines, building materials mines, and chemical mines, among others. Mine size (also known as production capacity) is typically expressed in terms of annual or daily output. Annual output refers to the amount of ore a mine produces annually. Based on the size of the output, mines are categorized into three types: large, medium, and small. The size of a mine must be commensurate with its economically reasonable service life. This is the only way to save on infrastructure costs and reduce costs. In the mining process, mining operations consume the most manpower, material resources, and capital, yet also offer the greatest potential for reducing mining costs. The primary means of reducing mining costs is to improve labor productivity and product quality while reducing material consumption.

[0003] With the rapid development of human science and technology, human demand for energy is gradually increasing. Mines contain a large amount of natural mineral resources. When mining, it is necessary to install blasting tubes in the blasting holes and then carry out targeted blasting. The buried pipe device for mining blasting is a device specially used for mine blasting operations. The explosives are loaded into the pipe and the explosion is triggered by the detonator. Through the buried pipe device, the explosion energy can be concentrated in a specific area, thereby effectively destroying the rock or soil for mining activities.

[0004] The above device has the following defects: when blasting tubes are installed in blasting holes on some inclined or vertical roads, the blasting tubes themselves are prone to displacement or even slipping during or before the explosion, which makes it inconvenient to fix them in multiple directions. This causes deviations in the blasting effect and affects the accuracy. Therefore, a mining engineering mine blasting device is proposed to solve the above problems. Utility Model Content

[0007] As a further description of the above technical solution: the anti-slip mechanism includes a concave groove, the concave groove is opened on the inner wall of the side of the bolt, the inner wall of the side of the concave groove is slidably connected with a convex plate, one side inner wall of the bolt is fixedly connected with a tension spring, one side outer wall of the convex plate is fixedly connected with a positioning rod, and a limiting hole is opened on the side outer wall of the fixed plate.

[0008] As a further description of the above technical solution: there are two thread grooves, which are respectively opened on the top inner wall of the blasting splint and the auxiliary sleeve.

[0009] As a further description of the above technical solution: the outer side wall of the inclined groove is provided with a sharp surface, the clamping ring sleeve passes through the inner side wall of the blasting splint, and the bolt is threadedly connected to the inner side wall of the clamping ring sleeve.

[0010] As a further description of the above technical solution: the side outer walls of the fixed disk and the retaining ring sleeve are respectively fixedly connected with wear-resistant pads, the fixed disk is clamped on one side outer wall of the auxiliary sleeve, and the top outer wall of the adjusting disk is provided with an indicator mark.

[0011] As a further description of the above technical solution: a frosting pad is fixedly connected to the side outer wall of the convex plate, and one end of the tension spring away from the bolt is fixedly connected to the side outer wall of the convex plate.

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.

[0024] Reference Figure 1-Figure 3The utility model provides an embodiment: a mining engineering mine blasting device, including a blasting tube body 1, a blasting splint 2 and a sub-sleeve 3 are provided on the blasting tube body 1, a positioning mechanism 4 is provided on the blasting splint 2, and an anti-slip mechanism 5 is provided on the positioning mechanism 4. The positioning mechanism 4 includes a threaded groove 41, the threaded groove 41 is opened on the top inner wall of the blasting splint 2, and the side inner wall of the threaded groove 41 is threadedly connected with an anchor 44, which is deeply fixed to the ground by setting the anchor 44, and the top of the anchor 44 is fixed to the ground. The end is fixedly connected with an adjusting disk 43, and the outer wall of the bottom end of the anchor 44 is provided with an oblique groove 45. The oblique groove 45 facilitates the anchor 44 to penetrate deeper into the soil. The bottom end of the anchor 44 is provided with a through hole 46. The through hole 46 does not affect the original fixed soil or hard stone in the through hole 46 in the ground, so that it assists the anchor 44 to be fixed. The side outer wall of the blasting splint 2 is clamped with a clamping ring sleeve 47, and the side inner wall of the auxiliary sleeve 3 is rotatably connected with a bolt 48, and the side outer wall of the bolt 48 is fixedly connected with a fixing disk 49.

[0025] Reference Figure 2-Figure 4 There are two thread grooves 41, which are respectively opened on the top inner walls of the blasting splint 2 and the auxiliary sleeve 3. The side outer wall of the inclined groove 45 is provided with a sharp surface. The sharp surface is provided to facilitate the rotation and insertion of the anchor nail 44. The snap ring sleeve 47 passes through the inner wall of one side of the blasting splint 2, and the bolt 48 is threadedly connected to the inner wall of the side of the snap ring sleeve 47. The fixed plate 49 and the side outer wall of the snap ring sleeve 47 are respectively fixedly connected with wear-resistant pads. The fixed plate 49 is clamped on the outer wall of one side of the auxiliary sleeve 3. The top outer wall of the adjusting disk 43 is provided with an indicator mark. The indicator mark is provided to prompt the rotation direction of the adjusting disk 43. The side outer wall of the blasting tube body 1 is clamped with the blasting splint 2, and the side outer wall of the blasting tube body 1 is clamped with the auxiliary sleeve 3. The auxiliary sleeve 3 is symmetrical with the blasting splint 2.

[0026] Reference Figure 3-Figure 4 The anti-slip mechanism 5 includes a concave groove 51, which is opened on the inner wall of the side of the bolt 48. The inner wall of the side of the concave groove 51 is slidably connected with a convex plate 52, and the inner wall of one side of the bolt 48 is fixedly connected with a tension spring 53. By setting the tension spring 53, a continuous tension is generated on the convex plate 52. A positioning rod 54 is fixedly connected to the outer wall of one side of the convex plate 52. The positioning rod 54 is inserted into the limiting hole 55 of the auxiliary sleeve 3 to limit the rotation of the fixed plate 49 and the bolt 48. A limiting hole 55 is opened on the outer wall of the side of the fixed plate 49, and a frosting pad is fixedly connected to the outer wall of the side of the convex plate 52.

[0027] Working principle: According to the different sizes of the blasting tube body 1, the blasting splint 2 and the auxiliary sleeve 3 are attached to the side outer wall of the blasting tube body 1, and then the convex plate 52 is rotated to rotate the bolt 48. The bolt 48 rotates and approaches the inside of the clamping ring sleeve 47, so that the fixing plate 49 pushes the auxiliary sleeve 3 close to the blasting splint 2, and then the blasting tube body 1 is clamped and fixed, and at the same time, the blasting splint 2 and the auxiliary sleeve 3 are attached to the ground. Then the convex plate 52 is released so that under the tension of the tension spring 53, the positioning rod 54 is aligned and inserted into the limiting hole 55 of the fixing plate 49 and the auxiliary sleeve 3, so that the bolt 48 is rotated to limit and prevent it from falling off, and then the blasting splint 2 is stepped on to rotate the anchor nail 44. Under the thread push of the thread groove 41, the anchor nail 44 makes the inclined groove 45 drill into the ground. At the same time, the ground object structure in the through hole 46 where the anchor nail 44 is inserted into the ground is not damaged, and the auxiliary anchor nail 44 is swung left and right for positioning, thereby reducing damage to the internal structure of the ground and affecting the fixing effect of the anchor nail 44.
