Technical Field

The invention relates to the technical field of blasting network connection, and in particular to a portable nonel blasting network connection device.

Background Art

With the continuous development of urban construction and infrastructure, there are more and more large-scale and complex blasting projects. The application of blasting four-way pipes, which are coupling elements based on the reflection principle, in the connection of large-scale detonating cord blasting networks is becoming more and more widespread. The four-way pipe is a plastic product and is not a controlled item. It has the characteristics of low cost, convenient transportation and storage, and low explosion transmission sound. The traditional four-way pipe is composed of a U-shaped reflective head and a ring-shaped through-hole fastening nut connected by threads. Due to the processing technology and the extrusion of the detonating cord, the threads cannot be completely tightly connected, and the resulting gaps are easy to enter foreign objects, affecting the smoothness of the reflective arc surface and causing explosion rejection. In the project, it is often necessary to tighten it with insulating tape on the basis of the threaded connection. At the same time, the four connected detonating cords need to pass through the ring-shaped through-hole fastening nuts, which brings great inconvenience to the construction in large-scale non-electrical network connections, especially when operating at night.

DETAILED DESCRIPTION

The embodiment of the present application provides a convenient detonating cord blasting network connection device to solve the technical problems in the prior art that the connector is easily squeezed to produce gaps, which reduces the locking quality, affects the reflection reliability, and has complicated assembly operations.

In order to better understand the above-mentioned technical scheme, the above-mentioned technical scheme will be described in detail below in combination with the accompanying drawings and specific implementation methods. It should be understood that the embodiments of the present invention and the specific features in the embodiments are detailed descriptions of the technical scheme of the present application, rather than limitations on the technical scheme of the present application. In the absence of conflict, the embodiments of the present application and the technical features in the embodiments can be combined with each other.

Referring to FIG. 1 and FIG. 3 , a convenient detonating cord blasting network connection device includes: a detonating cord reflector head and a parallel double tie matched with the tail end of the detonating cord reflector head.

That is to say, compared with the structural mode of the nut and the reflective head used in the prior art, this embodiment provides a connection and locking structure of the reflective head with the cable tie. The flexible structure of the cable tie achieves flexible and convenient tightening and locking performance. The problem of the gap between the nut and the reflective head due to the high structural strength is avoided, thereby improving the reliability of the guide; on the other hand, compared with the nut matching structure, the present application is more adaptable to complex environments, such as small spaces, dark nights and other harsh construction environments, so that it can still operate efficiently in such environments.

1 and 2 , the parallel double tie comprises: a tie head and a first tie and a second tie 3 connected thereto.

The tie head is provided with a first tie hole 2 and a second tie hole 1 which are matched with the first tie and the second tie 3 respectively.

That is, the tie heads that cooperate with the first tie and the second tie belong to two functional parts on one tie head. Of course, they can also be connected by sliding, that is, the tie head of the first tie can rotate a certain angle relative to the tie head of the second tie; for example, a pivot connection structure is established between the two tie heads through a pivot shaft, so as to adapt to the traction of the detonating cord to a certain extent and avoid rigid traction affecting the stability of the fastening structure.

Among them, the first cable tie cooperates to lock the tail end of the detonating cord reflector head, and the second cable tie is suspended outside the tail end of the detonating cord reflector head to lock the connected detonating cord body, that is, to form a two-stage locking to improve the locking quality.

Referring to Fig. 3, a strip-shaped groove 7 is provided on the tail end surface of the detonator reflector head, and a strip-shaped protrusion 4 matching with the strip-shaped groove is provided on the front side of the first cable tie.

The reverse side of the first cable tie and the reverse side of the second cable tie are both provided with sawtooth protrusions 5, and the first cable tie hole and the second cable tie hole are both provided with matching locking teeth as the locking structure of the cable tie. When in use, the strip convex strip 4 is matched with the strip concave groove 7. It is worth noting that the secondary concave is radially arranged, so that when the cable tie is locked, the first cable tie can avoid radial sliding, thereby improving the reliability of fastening.

Furthermore, in order to improve insertion efficiency, the free ends of the first cable tie and the second cable tie are respectively configured as trapezoidal plugs.

In this embodiment, the detonating cord reflector head includes: a reflector cap and a beam tube; the reflector cap is fixed to the top of the beam tube to form a cylinder with a closed top; that is, it reflects at the top, and the tail end is used for inserting the fastened detonating cord.

The outer wall of the bundle tube is provided with a strip-shaped groove which matches with the strip-shaped protrusion.

The upper part of the inner cavity of the cylinder is a reflection cavity for reflecting detonation, and the lower part is a restraining tube cavity for restraining the detonating tube.

Generally speaking, the inner wall of the reflective cap is a spherical surface. The spherical radius of the spherical surface is greater than the inner cavity radius of the library. The detonating cord reflective head is a four-way reflective head.

Furthermore, a slit is provided on the tube wall of the bundle tube in the axial direction and penetrates the tube wall. When the cable tie is tightened, the bundle tube can contract radially to improve the compression effect. Generally, there are four slits.

The method of using the portable four-way device for connecting the nonel blasting network is as follows:

Align the ends of the four detonating tubes 6 and insert them into the arc cavity of the threaded reflector head;

Insert the 3 to 5 strip-shaped protrusions on the front side of the parallel double tie into the 3 to 5 strip-shaped grooves on the outer wall of the opening section of the reflective head;

Pass the trapezoidal end of the first cable tie through the large tooth cavity of the cable tie head, tighten the cable tie, and lock the reflective head;

Pass the trapezoidal end of the second cable tie through the small tooth cavity of the cable tie head, tighten the cable tie, and lock the detonating cord.

An open-type cable tie is used to directly lock the U-shaped reflective head to replace the circular structure of the traditional four-way, so that the detonating cord does not need to be passed through the circular structure of the traditional four-way, which saves time and is easy to operate; a second cable tie is used to lock the detonating cord to prevent the connected network line from being pulled apart, affecting the safety of the overall blasting network. The present invention has the characteristics of simple structure, low cost, and easy operation, and is more effective in large-scale and complex demolition blasting network connections and night construction projects.

One or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

The convenient detonating cord blasting network connection device provided in the embodiment of the present application is provided with a matching parallel double tie at the tail end of the detonating cord reflector head, wherein the first tie locks the tail end of the detonating cord reflector head to compress the detonating cord reflector head, thereby realizing a convenient locking operation and a highly reliable locking structure; the detonating cord is locked by the second tie, that is, the detonating cord is first pressed together before entering the detonating cord reflector head, so as to avoid the posture change of the detonating cord involving the compression of the detonating cord reflector head to affect the locking structure, thereby ensuring the entry of foreign matter into the reflector head and the reliability of the reflective structure. More importantly, the two-stage fastening structure can fully improve the reliability of the fastening structure while the locking operation is also very convenient. The use of this device has a significant effect on large-scale, complex, and night-time connection construction blasting projects.

Furthermore, by providing a strip convex strip on the front side of the first cable tie and providing a matching strip groove at the rear end of the detonating cord reflector head, the cable tie can be prevented from axially sliding at the rear end of the detonating cord reflector head after locking, thereby ensuring the reliability of locking.

Furthermore, by setting a beam tube with a smaller radius, a certain degree of positioning and tightening can be achieved to ensure the locking quality. A notch can also be opened on the beam tube wall so that it can contract radially under pressure, further compressing the detonating tube to improve the tightening reliability and ensure the reliability of the warning.

Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to examples, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
