Description

Technical Field

[0001] This utility model provides a snap-fit ​​shaped charge blasting tube device, belonging to the technical field of tunnel engineering equipment, and particularly relates to a snap-fit ​​shaped charge hydraulic blasting tube device. Background Technology

[0002] Currently, shaped charge blasting technology can effectively improve the blasting profile shaping effect and smooth blasting effect. By using different shaped charge materials and different shapes, it can influence and control the detonation direction and rock fragmentation effect, directionally cut the rock mass and form rock blasting fractures along the cut direction. This can effectively improve the blasting effect and reduce damage to the surrounding rock of the tunnel profile. Under certain circumstances, shaped charge blasting technology can also reduce the amount of explosive in the blast holes, reduce the number of cut holes, and improve the quality of cut holes.

[0003] Current shaped charge blasting technology uses shaped charge tubes with limited shape and material variety, resulting in only average blasting performance in multiple directions. This fails to meet the blasting effect requirements during construction, making it difficult to alter the stress field and the effects of the explosive gases on the rock mass, control the different cracking directions of rock fractures, and hinder construction progress. Further improvements are needed. Furthermore, loading and unloading the shaped charge tube often requires operation from one end of the tube, which is inconvenient and affects blasting efficiency.

[0004] Therefore, it is necessary to propose a snap-fit ​​shaped charge hydraulic blasting tube device that reduces the amount of explosives, improves the smooth blasting effect and construction quality of the tunnel profile, and saves the time required for charging. Utility Model Content

[0005] The technical problem this invention aims to solve is that existing shaped charge tubes have low loading efficiency, mediocre blasting effect, and poor construction quality.

[0006] To solve the above problems, the proposed technical solution is as follows: a snap-fit ​​energy-concentrating blasting tube device, comprising a plastic shell; one side of the plastic shell is an open structure, and a snap-fit ​​structure is provided at the opening of the plastic shell; concave energy-concentrating grooves are provided on the left and right sides of the plastic shell, and a plurality of energy-concentrating holes are opened in the energy-concentrating grooves; the cross-section of the energy-concentrating groove is a V-shaped cross-section.

[0007] Preferably, the fastening structure includes two mutually wrapping and fitting fastening strips, which are fixedly connected to the opening of the plastic shell; one of the fastening strips has a fastening hole, and the other fastening strip has a fastening block fixedly connected to it, with the fastening block inserted into the fastening hole.

[0008] Preferably, the energy-concentrating groove extends from top to bottom through the entire plastic shell, and the two energy-concentrating grooves form an integral structure.

[0009] Preferably, the energy-concentrating holes are circular, and the energy-concentrating holes are arranged at equal intervals in the energy-concentrating groove.

[0010] The beneficial effects of this utility model are:

[0011] 1. The plastic shell has an open structure on one side, and a fastening structure is provided at the opening of the plastic shell; by setting a plastic shell with an opening and using a fastening structure, it is convenient to open the plastic shell and to facilitate loading and unloading of explosives, thereby saving loading time and improving the efficiency of blasting operations.

[0012] 2. The plastic shell has concave energy-concentrating grooves on both sides, and several energy-concentrating holes are opened in the energy-concentrating grooves. The cross-section of the energy-concentrating grooves is V-shaped. The change in the structure of the energy-concentrating grooves on both sides affects the stress field and the effect of the explosive gas on the rock mass during energy-concentrating blasting, thereby controlling the different cracking directions of the rock mass.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] according to Figure 1-4 As shown: This utility model provides a snap-fit ​​shaped charge explosive tube device, including a plastic shell 1; one side of the plastic shell 1 is open, and a snap-fit ​​structure 4 is provided at the opening of the plastic shell 1 to facilitate opening the opening of the plastic shell 1 for loading and unloading explosives; concave shaped charge grooves 3 are provided on the left and right sides of the plastic shell 1, the cross-section of the charge grooves 3 is V-shaped, the charge grooves 3 penetrate the entire plastic shell 1 from top to bottom, and the two charge grooves 3 form an integral structure; a plurality of charge holes 2 are opened in the charge grooves 3, the charge holes 2 are circular, and the charge holes 2 are arranged at equal intervals in the charge grooves 3, which can improve the uniformity of explosive charge.

[0021] like Figure 5As shown, the fastening structure 4 includes two fastening strips that fit and wrap around each other. The two fastening strips are fixedly connected to the opening of the plastic shell 1. One of the fastening strips has a fastening hole, and the other fastening strip has a fastening block fixedly connected to it. The fastening block is inserted into the fastening hole. The fastening structure 4 can be easily disassembled and assembled by setting up the two fastening strips.

[0022] The principle of this utility model

[0023] like Figure 5 As shown, when loading explosives into the plastic shell 1 of the shaped charge tube, it is not necessary to put the explosives into the tube from the end of the tube. Instead, the fastening structure 4 can be opened directly to expose the opening of the plastic shell 1. Explosives can then be loaded directly into the tube through the opening, which greatly improves the convenience of loading and unloading explosives, saves loading time, and improves the efficiency of blasting operations.

[0024] When used in blasting, after drilling and slotting to form a slot, a certain amount of explosive and electronic detonators are placed in the shaped charge tube. The shaped charge slot 3 is aligned with the direction of the rock mass cracks to be opened. During the explosion, the shaped charge slot 3 and the shaped charge hole 2 can achieve the effect of focusing energy, changing the stress field and the effect of the explosive gas on the rock mass during shaped charge blasting, controlling the different cracking directions of the rock mass cracks, improving the blasting shaping effect, and improving the construction quality.

The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
