Abstract

The utility model provides a detonator and arouse the line to constitute that plastics detonator is mainly made by plastics the detonator inner wall scribbles one deck powder, arouse the line to be turned round by two little cable conductors tightly constitutes together, arouse line one end to insert detonator other end dew outside, that inserts detonator one end arouses the terminal surface of two little cables of line to flush, it is tight to arouse line and detonator to pass through the adhesive tape package. The utility model discloses a simple line that arouses replaces detonating needle, and the cost can be practiced thrift greatly to the simple safety of the method of ignition.

Description

A kind of plastic detonating tube

Technical field

The utility model relates to some and plants non-electric initiation technology, particularly a kind of plastic detonating tube not needing use detonating needle.

Background technology

Non-electric initiation technology is widely used in Blasting Excavation massif and mining blasting engineering.Traditional plastic detonating tube excites to detonate and to excite with special detonating needle.Detonating needle needs special factory to produce, and buys and needs expense, and another detonating needle uses several times, sparking excitation energy declines, and just can not excite detonator, needs to change to use new detonating needle, so in bursting work process, the consumption of detonating needle is comparatively large, adds production cost.

Utility model content

For solving the problem, the purpose of this utility model is, a kind of plastic detonating tube not needing detonating needle is provided, plastic detonating tube can utilize common telephonic communication cable as excitation line, and this excitation line is cost-saving, wide material sources, without the need to separately spending use, the consumption that simultaneously detonates is little, makes simple and convenient, and handling safety of detonating is reliable.

For realizing upper art object, the utility model is achieved through the following technical solutions:

A kind of plastic detonating tube, it is characterized in that, the detonator be mainly made of plastics and excitation line are formed, described detonator inwall scribbles one deck medicinal powder, described excitation line is tightened by two little cables and forms together, described excitation line one end is inserted the detonator other end and is exposed, and insert the end face of two little cables of the excitation line of detonator one end, described excitation line and detonator are packed tightly by adhesive plaster.

Further, described excitation line length is 80-120mm, and excitation line inserts the length >=30mm of detonator.Be preferably 30-50mm.

Further, the single apparent diameter of two little cables of excitation line is 1.0mm, and inner core diameter is 0.5mm.

The beneficial effects of the utility model: 1, operation is reliable, easy to process; 2, cost saving; 3, detonate safe and reliable.

Accompanying drawing explanation

Fig. 1 is the structural representation of the utility model plastic detonating tube.

Detailed description of the invention

Plastic detonating tube described in the utility model is the detonator 2 be made up of excitation line 1, plastics, described detonator inwall scribbles one deck medicinal powder 3, described excitation line 1 is tightened by two little cables 4 and forms together, described excitation line 3 one end is inserted detonator 2 other end and is exposed, insert the end face of two little cables 4 of the excitation line 1 of detonator 2 one end, described excitation line 1 is packed tightly by adhesive plaster with detonator 2.

Instantiation of the present utility model: excitation line is made by the single little line in the communication signal cable of common wireline phone, the apparent diameter of solid wire is 1.0mm, and inner core diameter is 0.5mm, and length is 80-120mm, centre clenches, and inserts detonator one end scissors and cuts flat.Excitation line is inserted detonator 30-50mm, with adhesive plaster sharp normal and detonator packed tightly and prevent excitation line from getting loose.Excitation line another two ends access detonating power supply, after powder charge work in every to be done, switches on power, two excitation line be inserted in detonator are discharged, the electric pyrogenic process produced, just detonator inwall medicinal powder can be excited and detonate, detonator detonates and can be delivered to detonation tube detonator along detonator inwall.
