Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of blasting technique, especially relate to a busbar quick connecting device for blasting. BACKGROUND

[0002] In the blasting engineering, the busbar is often laid in the working face or the blasting area to connect the detonators of each blast hole together to form a blasting network, and the busbar needs to be extended to a safe detonation point. The working face and the extended busbar for detonation are often more than 300 meters, and the general busbar specification is 200 meters per reel. In addition, in the actual operation process, in order to save costs, the busbar is often recycled. The post-blasting busbar cannot be 100% recycled, and generally, several lengths of intact busbar are selected for recycling. Therefore, in the actual process of laying the busbar, the connection between the busbars is often involved. On the other hand, due to the thinness of the busbar, the insulation layer is inevitably damaged or even the busbar is broken during the laying process, which causes the busbar to be grounded or disconnected during detonation and cannot be detonated. Therefore, when the insulation layer is damaged or broken during the inspection of the busbar, the two busbars need to be connected again. Therefore, in the actual blasting operation, there are several busbar connection points in the entire blasting network. At present, the connection between the busbars usually adopts the electrician connection method. The disadvantages of this method are as follows: first, it is time-consuming and inconvenient to connect, and the electrician tape needs to be prepared in advance; second, it requires high skills of the operator, and if the operator is not skilled, it often causes loose connection, short circuit, grounding and other situations; and third, the ordinary electrician tape is not waterproof, and additional waterproof measures need to be taken when laying on the ground in the presence of water. Therefore, the existing connection method has the defects of complexity and low reliability. CONTENT OF THE UTILITY MODEL

[0015] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following is combined with the embodiment, and the utility model is further explained in detail.

[0016] As Figures 1-4 shown, a kind of quick connecting device of blasting busbar, including base bin 1 and bin cover 2, base bin 1 inside is provided with terminal post 3, terminal post 3 is provided with first slot 4 and second slot 5 that are perpendicular to each other, the bottom of first slot 4 and second slot 5 is flush, second slot 5 is sequentially provided with upper slot 6 and lower slot 7 from top to bottom, arc transition section 8 is arranged between upper slot 6 and lower slot 7, upper slot 6 is matched with the outer diameter of the insulating skin of blasting busbar, lower slot 7 is matched with the diameter of the core of blasting busbar, bin cover 2 is provided with line pressing column 9, line pressing column 9 includes middle line pressing plate 10 and side wing line pressing plate 11 located in the two sides of middle line pressing plate 10, after bin cover 2 is covered on base bin 1, middle line pressing plate 10 is located in first slot 4, two sides of side wing line pressing plate 11 are located in the two sides of terminal post 3, line groove one 12 is provided on the top of the side wall of base bin 1.

[0017] In use, the number of terminals 3 can be installed according to actual conditions, and the two blasting busbars to be connected can correspond to 1-3 terminals 3, so that the reliability after connection is higher. If multiple groups of blasting busbars are connected, multiple groups of terminals 3 are correspondingly provided, and other components are correspondingly provided. The terminal 3 is made of conductive metal material such as copper material. When connecting, the two blasting busbars to be connected are placed in the upper slot 6 of the second slot 5 in sequence, and the insulating sheath of the blasting busbar should be tightly attached to the side wall of the upper slot 6. Then the cover 2 is covered and pressed down. During the process, the intermediate pressing plate 10 and the side wing pressing plate 11 press the blasting busbar at the same time, and the blasting busbar is gradually pressed into the lower slot 7 from the second slot 5. After the friction of the blasting busbar with the arc transition section 8 in the second slot 5 and the inner wall of the lower slot 7, the insulating sheath of the blasting busbar is peeled off, and the blasting busbar is connected with the terminal 3. Since the blasting busbar is a copper core wire wrapped with a polyvinyl chloride insulating layer, the insulating layer can be crushed with a fingernail in addition to a wire stripping tool. During the process of pressing the blasting busbar into the lower slot 7, the opening of the second slot 5 is gradually tightened, so that the insulating sheath can only be damaged and separated from the copper core wire to enter the lower slot 7. The width of the side wall of the lower slot 7 can be narrowed, so that it is easier to contact with the copper core wire. This device solves the problems of time-consuming, electric leakage, short circuit and high requirement for operators during the connection of the busbar, and achieves the purpose of quick connection, simple operation, safety and stability of the busbar, and guarantees the efficiency and safety of the blasting operation.

[0018] The arc transition section 8 is uniformly provided with protrusions 13, which can form a structure similar to a washboard, so that the insulating sheath can be more effectively removed.

[0019] The slot of the upper slot 6 has an arc section 14, and the inner wall of the upper slot 6 is provided with a blade 15. When the blasting busbar is placed in the upper slot 6, the insulating sheath can be cut under the action of the blade 15, which further ensures that the insulating sheath can be separated from the copper wire after subsequent processing (at least the part of the blasting busbar in contact with the terminal 3).

[0020] The base bin 1 is provided with a surrounding barrier 16, the terminal 3 is located inside the surrounding barrier 16, and the surrounding barrier 16 is provided with a hydrophobic oil material inside. The top of the surrounding barrier 16 is provided with a wire slot 2 17, and the wire slot 2 17 is provided with a rubber pad. The rubber pad has a cutout in the middle, and the blasting busbar is located in the cutout. Alternatively, a sealing sleeve is provided on the blasting busbar, and the sealing sleeve is matched with the wire slot 2 17. The bottom of the cover 2 is provided with a sealing gasket, and the sealing gasket contacts the top of the surrounding barrier 16 after the cover 2 is covered on the base bin 1. The hydrophobic oil material can play a role in waterproofing and dustproofing, ensuring the reliability of the connection. Similarly, the wire slot 1 12 is provided with a rubber pad, and the rubber pad has a cutout in the middle. The blasting busbar is located in the cutout, or a sealing sleeve is provided on the blasting busbar, and the sealing sleeve is matched with the wire slot 1 12.

[0021] The cover 2 is hingedly connected with one end of the base 1 through a pin shaft, and the cover 2 is fixed with the other end of the base 1 through a buckle 18, so that the cover 2 is connected with the base 1, and the use is convenient and reliable.

[0022] The above is only a preferred embodiment of the present application.
