Description
Technical field
It the utility model is related to blasting gear technical field, more particularly to gas expansion pipe.
Background technology
Gas blast equipment is by thermal evaporation expansion using gas, and then quick release gases at high pressure reach disrumpent feelings rock
Or the purpose of coal breakage.Because it has explosion power controllable, power is big, and many advantages, such as not producing shock wave is widely used in
The fields such as city changes, urban construction and exploitation of mineral resources.
When implementing explosion using gas expansion pipe, gas expansion pipe is placed in the blast hole accomplished fluently in advance, then is filled.
During explosion, due to the enormous impact force of moment, when the frictional force of expansion tube and surrounding backfill thing is inadequate, it is possible to occur " flying pipe "
Phenomenon, i.e. during explosion, blasting cartridge flies out blast hole.When occurring to fly pipe, because situation is unexpected, and fly pipe height up to 200 meters,
And the track flown has uncertainty, scene is easily chaotic, if site operation personnel hide it is too late, may be by falling from high altitude
Gas expansion pipe is hit, damages.More importantly：Due in correlation technique, the expansion tube as blasting cartridge main component
It is made up of steel, if the expansion tube of steel, which drops, pounds operating personnel, necessarily causes personnel severely injured, in addition it is dead, cause great
Security incident, consequence are hardly imaginable.
How to avoid the generation of the serious accident caused by " flying pipe " from turning into gas expansion blasting technique needs to compel
Cut the technical problem of solution.
Therefore, actually it is necessary that providing a kind of new gas expansion pipe solves above-mentioned technical problem.

Compared with correlation technique, a kind of gas expansion pipe of the utility model.Gas is carbon dioxide or other gases.Its is swollen
The material of tube expansion replaces existing steel material by fiberglass.Due to the performance of glass-reinforced plastic material, the expansion tube of fiberglass can
Meet the requirement of high-strength low temperature.Moreover, compared with the expansion tube of steel, the expansion tube weight of fiberglass is lighter, that is, uses
Existing " flying pipe " phenomenon, though site operation personnel hide it is too late, it is hit by the gas expansion pipe of falling from high altitude, due to from glass
The material of steel is relatively light and soft, and the both ends of blasting cartridge are plastic material, may be sustained a slight injury by hit operating personnel, but necessarily
It is unlikely to hinder its life.It effectively prevent the generation of serious accident.In addition, the gas in gas expansion pipe can be titanium dioxide
Carbon, or in general air, and after explosion, expansion tube pops, but spiral shell core and the heat-generating pipe that is connected with spiral shell core can be from bodys
Screw thread at screw out, be continuing with.A kind of gas expansion tubular construction of the utility model is simple, practical, can effectively reduce cost and
Ensure the safety of operating personnel.

Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
The utility model is achieved in that provides a kind of gas expansion pipe referring to Fig. 1-2, the utility model, it is intended to solves
Certainly because fly pipe caused by cause serious accident the problem of.
The utility model is achieved in that a kind of gas expansion pipe, including：Expansion tube, upper plug head 2, charge valve 3, hair
Heat pipe.Tube expansion includes being used for housing the cylinder 1 of gas, and the gas in cylinder 1 is carbon dioxide or other gases.The one of cylinder 1
It is openend 12 to hold as blind end 11, the other end, and upper plug head 2 is located at the openend 12 of cylinder 1, and closed with expansion tube composition
Gas receiving space, charge valve 3 are used to be filled with gas into expansion tube, and heat-generating pipe is in cylinder 1；Wherein, expansion tube is by glass
Glass steel is made, and expansion tube is externally provided with winding layer 6, and upper plug head 2 is made of plastics.
Upper plug head 2 includes swivel nut 21 and spiral shell core 22；
Spiral shell core 22 is by being threaded into swivel nut 21；
Swivel nut 21 fills in the openend 12 of cylinder 1.
Charge valve 3 is check valve.Unidirectionally can only internally it inflate.
One end of positive and negative terminal 4 is connected with heat-generating pipe, and the other end runs through and stretches out spiral shell core 22.For top wiring knot
Structure, wiring are more convenient.
Positive and negative terminal 4 is pre-buried into spiral shell core 22 as inserts.
Charge valve 3 is arranged in spiral shell core 22 and between 2 positive and negative terminal 4.
Positive and negative terminal 4 is 2 metal bars for being used as both positive and negative polarity.
The blind end 11 of cylinder 1 is blocked by lower end cap 5 to be formed.
The seal groove for installing seal is equipped with lower end cap 5 and swivel nut 21.Sealing structure is easy to effectively block.
One of inventive point of the present utility model is that the material of expansion tube replaces existing steel material by fiberglass.Glass
The performance of steel is as follows：Fiberglass (FRP) is also referred to as GFRP, i.e. fiber-reinforced plastic, refers generally to unsaturated with glass fiber reinforcement
Polyester, epoxy resin and phenolic resin as matrix resin.Make the reinforced plastics of reinforcing material with glass fibre or its product, appellation is glass
Fibre reinforced plastics, or be fiberglass, non-conductive, stable performance, high mechanical strength, recycle less, it is corrosion-resistant.Can generation
For steel manufacture machine part and automobile, ship housing etc..Light and hard, relative density is between 1.5-2.0, only carbon steel
1/4-1/5, but tensile strength but approaches, even more than carbon steel, and specific strength can be compared with high-grade alloy steel.
Due to above performance, on the one hand, the material of fiberglass disclosure satisfy that the requirement of expansion tube, including can bear
The pressure for the carbon dioxide being filled with it, and can be used under low temperature state.On the other hand, compared with the expansion tube of steel, glass
The expansion tube weight of glass steel is lighter, even if there is " fly pipe " phenomenon, even if site operation personnel hide it is too late, by falling from high altitude
Gas expansion pipe it is hit, due to from fiberglass material it is relatively light and soft, plug is also plastics, therefore will not be to operating personnel
Cause very major injury, effectively prevent the generation of serious accident, and the expansion tube of glass steel material pop after can become
Fragment, to operating personnel without security threat.
The two of inventive point of the present utility model are that upper plug head 2 uses split-type structural, including swivel nut 21 and spiral shell core 22；It is quick-fried
After broken, expansion tube pops, and to be disposable, but spiral shell core 22 and the heat-generating pipe that is connected with spiral shell core 22 can be at the screw threads in body
Screw out, be continuing with.Effectively reduce cost.
The three of inventive point of the present utility model are that charge valve 3 and positive and negative terminal 4 are respectively positioned on the upper of gas expansion pipe
Portion, i.e. inflation and wiring are easy to operate on the top of gas expansion pipe.
A kind of gas expansion tubular construction of the utility model is simple, practical, can effectively reduce cost and ensure operating personnel's
Safety.
