Description

Technical Field

[0001] The utility model relates to the technical field of blasting tubes, and more particularly to a blasting tube used in mine development. Background Art

[0002] In the field of mining, in order to obtain various valuable mineral resources, it is necessary to effectively crush and excavate the mountain or underground mineral layer. Blasting technology, as an efficient and widely used means, can change the physical structure of the rock in a short time, breaking it into blocks that are convenient for subsequent excavation and transportation, greatly improving the efficiency of mining. In the early days, mine blasting often used a combination of fuse and detonator to detonate explosives. The fuse transmits flames to the detonator through combustion, and then detonates the explosives. This method has obvious safety hazards. For example, the burning speed of the fuse is easily affected by the external environment, resulting in unstable detonation time. In addition, in a mining environment with flammable and explosive gases such as gas, open flames can easily cause explosion accidents. In view of the many shortcomings of traditional blasting equipment, blasting tubes came into being. Existing blasting tubes are usually placed directly vertically in pre-drilled holes. However, in some special cases, blasting tubes need to be installed tilted or inverted. Since the outer surface of most existing blasting tubes is a smooth surface, it is not convenient for special installation. Its flexibility and practicality are poor, which may cause the blasting tube to slip or even be unable to be installed, thereby greatly reducing the mining efficiency of the mine to a certain extent. In order to solve the shortcomings of the existing technology, we propose a blasting tube for mine excavation. Utility Model Content

[0022] By pushing the sliding frame 21 to slide, the connecting rod 22 is driven to slide on the inner surface of the support limit block 23, so that the connecting rod 22 rotates on the inner wall of the sliding frame 21, and then drives the nail column 25 to be inserted into the inner wall of the blasting hole, which facilitates the fixed installation of the blasting tube body 1, thereby improving the flexibility and practicality of the blasting tube, and greatly improving the mining efficiency of the mine.

[0023] Among them, the auxiliary component 3 includes a fixing ring 31, the inner wall of the fixing ring 31 is threadedly connected with a fixing bolt 32, the inner wall of the fixing ring 31 is slidably mounted with a sliding rod 33, the upper end outer surface of the sliding rod 33 is fixedly mounted with a top plate 34, the upper outer surface of the top plate 34 is fixedly mounted with a striking block 35, the fixing ring 31 is attached to the outer wall of the blasting tube body 1, the fixing bolt 32 is threadedly connected to the inner wall of the blasting tube body 1, and the sliding rod 33 is fixedly mounted on the upper outer surface of the sliding frame 21;

[0024] By fixing the fixing ring 31 on the inner wall of the blasting tube body 1, and then hammering the striking block 35 to push the slide rod 33 to slide on the inner wall of the fixing ring 31, the slide rod 33 pushes the slide frame 21 to slide, which facilitates the use of the fixing assembly 2, thereby facilitating the installation of the blasting tube body 1, and thus greatly improving the adaptability of the blasting tube to a certain extent, further improving its mining efficiency.

[0025] Among them, there are four connecting rods 22, and the four connecting rods 22 are symmetrically installed on the inner wall of the sliding frame 21.
