Description

TECHNICAL FIELD

[0001] The utility model belongs to the engineering blasting technical field, concretely relates to an integrated plugging shaped charge tube. BACKGROUND

[0002] In the process of coal seam mining, the working face roof needs to collapse in time, and if the collapse is not timely or sufficient, it will cause large area roof hanging on the working face, which will bring greater stress concentration on both sides or front of the working face, seriously affecting the stability of the surrounding roadway, and even causing large area strong pressure on the working face, inducing rock burst or coal and gas outburst. The blasting pre-splitting method is used to make the roof collapse in time, which is a common technical measure, and the shaped charge tube can control the pre-splitting direction and make the energy concentrated and directional release, thereby producing better roof pre-splitting effect.

[0003] At present, when the emulsion explosive is installed in the commonly used shaped charge tube and the detonator is installed, due to the small opening part of the shaped charge tube, it is difficult for the hole sealing body to enter, and the outer package of the hole sealing body is easily damaged. Secondly, the shaped charge tubes on the market are mostly closed, and the position of the hole sealing body or the detonator is not easy to observe when they enter the shaped charge tube. At the same time, when the shaped charge tube enters the blast hole, it is easy to slide down. For the deep and long drill hole, the length of a single shaped charge tube is not long enough, and it is troublesome and not reliable to connect, which affects the work efficiency.

[0007] As a further improvement of the utility model, the shaped charge pipeline and the receiving port are made of high-strength plastic.

[0008] As a further improvement of the utility model, the receiving port is in the shape of a horn.

[0009] As a further improvement of the utility model, a fixing plug is arranged on the outside of the shaped charge pipeline, and the fixing plug is inserted into the outside of the shaped charge pipeline through the impact hole.

[0010] As a further improvement of the utility model, the fixing plug comprises a horizontal rod and elastic support rods on both sides.

[0011] The utility model discloses a beneficial effect compared with prior art lies in:

[0012] The utility model discloses adopt high -strength plastics as the whole manufacturing material, has promoted the practicality of device, in addition, the impact hole is established on the both sides of the shaped charge tube, on one hand can observe the position of the hole sealing body, on the other hand can adjust the position of explosive impact. The fixed plug is provided simultaneously, the shaped charge tube is clamped in the blasthole through the elastic support rod of the both sides of fixed plug and is not easy to fall, promotes installation efficiency, and the shaped charge tube one end is provided with the receiving port, can be connected through the threaded interface when the blasthole is deep, convenient and reliable. Promote work efficiency. BRIEF DESCRIPTION OF DRAWINGS
