Problems solved by technology

[0004] But this method often just is arranged on the surface of detonation point and detonates explosives, and explosives can only be blasted on the surface of the area to be detonated. When the detonated area is a certain thickness, the effect of only blasting on the surface is not ideal. For this reason, We propose a blasting device and method of use thereof

Embodiment 1

[0032] Such as figure 1 and 3 As shown, the present embodiment provides a blasting device comprising a main blasting head 2, an outer ring body 3 and a drill body 1, the main blasting head and the outer ring body are coaxially mounted on the front end of the drill body, the The outer ring body is located outside the rear end of the main blasting head; the main blasting head is used to extend into the area to be detonated, and is mainly used to detonate the central area of ​​the area to be detonated. When using, match and install the drill body on the corresponding drilling machine (the drilling machine here is a common drilling machine, but after removing the drill bit on the commonly used drilling machine, install the drilling body on the corresponding drilling machine through the mounting hole 101), start the drilling machine , can drive the drill body to rotate, thereby driving the main blasting head to rotate to carry out drilling operations in the area to be detonated, s...

Embodiment 2

[0042] Such as figure 2 and 3 As shown, the present embodiment provides a blasting device comprising a main blasting head 2, an outer ring body 3 and a drill body 1, the main blasting head and the outer ring body are coaxially mounted on the front end of the drill body, the The outer ring body is located outside the rear end of the main blasting head; the main blasting head is used to extend into the area to be detonated, and is mainly used to detonate the central area of ​​the area to be detonated. When in use, match and install the drill body on the corresponding drilling rig (the drill body is installed on the corresponding drilling rig through the installation hole 101), start the drilling rig, and drive the drill body to rotate, thereby driving the main blasting head to rotate to carry out drilling operations in the area to be detonated , the main blasting head can be extended into the inside of the detonation area, so as to facilitate the detonation of the central area...

Embodiment 3

[0052] On the basis of embodiment 1 or 2, the emulsion explosive can also be filled in the drill pipe, the emulsion explosive in the drill pipe and the emulsion explosive in the drill bit are in a connected state, and the emulsion explosive in the drill bit can be detonated by the detonation index, and corresponding Detonate the emulsion explosive in the drill pipe. The drill bit is made of hard alloy, the drill rod is made of cast iron, and the outside is covered with high-speed steel, which not only ensures the strength of the drill bit, but also ensures that the drill bit and the drill rod can be blasted smoothly when the explosive explodes, achieving the expected Blast effect.

[0053] The using method of the blasting device of the present invention comprises the following steps:

[0054] (1) Match and install the drill body on the corresponding drilling rig, align the main blasting head with the center of the area to be detonated, start the drilling rig to drill until al...

Abstract

The invention belongs to the technical field of blasting, and discloses a blasting device, comprising a main blasting head, an outer ring body and a drill body, the main blasting head and the outer ring body are coaxially installed on the front end of the drill body, and the outer ring body is located Outer side of the rear end; on the outer ring body, a plurality of first auxiliary blasting heads are arranged inclined toward the inside, and the plurality of first auxiliary blasting heads are evenly arranged on the inner circumference of the outer ring body; on the outer ring body, a plurality of first auxiliary blasting heads are arranged The second auxiliary blasting head, a plurality of second auxiliary blasting heads are evenly arranged on the outer circumference of the outer ring body; the first auxiliary blasting head, the second auxiliary blasting head and the main blasting head have the same structure. The invention also discloses a method of using the blasting device, which can make the main blasting head, all the first auxiliary blasting heads and all the second auxiliary blasting heads extend into the area to be detonated, and can be detonated inside the area to be detonated. The effect is better and the work efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of blasting, and in particular relates to a blasting device and a using method thereof. Background technique [0002] In large-scale projects such as railways, mines, and reservoirs, the role of blasting technology is very important. Blasting technology is used in mining and road construction, digging tunnels, and demolishing old buildings in cities. With the development of economy and the increase of engineering construction, blasting has attracted more attention. [0003] As a science and technology, blasting is widely used, but it is undoubtedly the most important and common application in engineering. Mining and mountain opening, railway and road repairing use drilling and blasting to excavate tunnels, and water conservancy projects are also used in some cities. Also used to demolish buildings. Use the huge energy generated by the explosion of explosives to destroy the original structure of a certain ...
