Description

A device for connecting detonator cluster legs and detonators in the detonation network

technical field

The invention relates to blasting equipment, in particular to a device for connecting detonating tube cluster leg wires and detonators in a detonating network.

Background technique

In the current detonation tube detonation system, in the process of detonation network connection, the nonel ends of several nonel detonators are bound with adhesive tape to the outside of one, two or multiple detonators to form the transmission of the detonator. Explode the Internet. In order to ensure effective detonation transmission, the nonel must be in contact with the detonation detonator, and it is necessary to avoid overlap of the detonation tubes to ensure the quality of the detonation transmission. Therefore in the process of bundling, because there are many detonating tubes, the operation is very troublesome, which makes the construction speed slow down and inefficient. Simultaneously, because there are generally many connections, it is unavoidable that mistakes will occur, and some detonators cannot be detonated, which affects the detonation transmission of the entire detonation network. In light cases, there will be rework, which wastes a lot of manpower and material resources; in severe cases, there will be blind shots, which will affect the direction of the collapse of the exploded objects, or even fail to collapse, which violates the original design intention.

In view of this, the purpose of the present invention is to provide a device for connecting the nonel cluster leg wires and detonators in the detonation network, so that the connection between the detonation tube leg wires and the detonator is more convenient, and the detonation transmission accuracy of the detonation network can be improved. , can avoid unnecessary waste of manpower and material resources, and can reduce blasting accidents.

The purpose of the present invention is achieved through the following technical solutions:

The device for connecting the nonel cluster foot wire and the detonator in the detonation network, including a detonator sleeve, the inner diameter of the detonator sleeve is consistent with the outer diameter of the detonator, the detonator sleeve is hollow tubular, and one end of the detonator sleeve is uniform along its circumference. A plurality of strip-shaped grooves are opened, and the grooves communicate with the inside of the detonator sleeve, and one end of the detonating tube foot wire is stuck in the groove and contacts with the detonator placed inside the detonator sleeve.

Further, the grooved end of the detonator sleeve is connected to a truncated cone, and the large end of the truncated cone is connected to the detonator sleeve.

detailed description

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. It should be understood that the preferred embodiments are only for illustrating the present invention, but not for limiting the protection scope of the present invention.

As shown in Figure 1-4, the device for connecting the detonator cluster foot wire and the detonator in the detonation network includes a detonator sleeve 1, the inner diameter of the detonator sleeve is consistent with the outer diameter of the detonator, and the sections a and d of the detonator sleeve are hollow tubular. The detonating pins do not overlap, but are evenly distributed and closely contacted on the surface of the detonator. One end of the detonator sleeve is evenly provided with a number of strip grooves 2 along its circumference. The length of the grooves is section a and b. In order to enable the detonator to successfully detonate each detonator foot wire it is responsible for, the groove communicates with the inside of the detonator sleeve, and one end of the detonator wire wire is stuck in the groove and contacts the detonator placed inside the detonator sleeve . In this embodiment, the groove is semicircular in cross section.

Preferably, in order to prevent the nonel from being cut by the sharp edges and corners of the end of the detonator sleeve during construction, the end of the detonator sleeve with the grooved end is connected to the truncated cone 3a, c, and the large end of the truncated cone is connected to the detonator sleeve.

More preferably, in order to prevent the metal sheet of the detonator from splashing along the detonation direction during the detonation transmission process when the detonator is connected in the forward direction, the sections a and c of the truncated cone are solid.

The device for connecting the nonel cluster leg wires and detonators in the detonation network of the present invention makes the connection between the detonating tube leg wires and the detonators more convenient, and the operation is simpler, thereby shortening the connection time and improving the overall construction efficiency; in addition, It can make the nonel wire and the detonator in good contact, and can avoid the superposition of the nonel, thereby improving the detonation transmission accuracy of the detonation network, and avoiding blind shots due to the non-initiated detonator wire.
