Description
Technical field
The utility model belongs to mining technical field, is specifically related to a kind of explosion expansion tube.
Background technology
At present, in mining technology, in process for blasting excavation mine, conventional means are explosive blastings, this mode requires very high to the technological means of operating personnel in operation, due to the unstability of explosive, at high temperature, very easily blast when clashing into and meet spark, therefore, very easily cause danger in operation, even the demolition firing party of specialty carries out explosion also there is a lot of unsafe factor, effectively can not ensure the safety of operating personnel, in addition, explosive itself is as a kind of limiter stage article, at storage, the links such as management and use have strict requirement, need to drop into a large amount of manpower and materials to ensure, use cost is higher, and use examination formality during explosive comparatively loaded down with trivial details in China, strictly, use inconvenience, therefore, need a kind of cost lower, safe demolition set easy to use replaces explosive blasting.
Utility model content
The utility model overcomes the harm that current explosive blasting brings, and provides a kind of explosion expansion tube, does not have combustible and explosive articles, not easily blast in operation in the composition of this expansion tube, substantially increase the security in operating process.
Concrete technical scheme of the present utility model is:
A kind of explosion expansion tube, key point is, described expansion tube comprises initial and end both ends and is provided with the supervisor of the first blocking and the second blocking and is fixed on the arm of main pipe by the first blocking, arm inside is provided with gasifying agent and is arranged on the electric starter in the first blocking, the arm other end arranges sealing blocking, supervisor's stem is also provided with tube connector, and tube connector one end is connected with source of the gas or water source, the other end blocks and supervisor's inner space through first.
Described supervisor's stem is also provided with air vent, is sealed and installed with plug in air vent, and air vent inwall and plug outer wall are threaded connection mode and fix.
Described supervisor, arm, the first blocking, the second blocking and sealing blocking are PVC material and make.
Described tube connector is that metal material is made.
The beneficial effects of the utility model are: this expansion tube in supervisor, fill air or water replaces explosive expanding blasting, the expansion of air and water by arm rapidly high temperature complete, not containing combustible and explosive articles in expansion tube, can not in operation because collision or spark meet accident blast, the security used improves greatly, and each several part of expansion tube is common items, and cost is lower, and do not belong to strict control article, use and prepare more for convenience.

In accompanying drawing, 1, supervisor, the 2, arm, 3, first blocking, the 4, second blocking, 5, sealing blocking, 6, tube connector, 7, electric starter, 8, fixture, 9, air vent, 10, plug.
Detailed description of the invention
The utility model relates to a kind of explosion expansion tube, described expansion tube comprises initial and end both ends and is provided with the supervisor 1 of the first blocking 3 and the second blocking 4 and is fixed on the arm 2 of supervisor 1 inside by the first blocking 3, arm 2 inside is provided with gasifying agent and is arranged on the electric starter 7 in the first blocking 3, arm 2 other end arranges sealing blocking 5, be responsible for 1 stem and be also provided with tube connector 6, tube connector 6 one end is connected with source of the gas or water source, the other end through first block 3 be responsible for 1 inner space.
Specific embodiment, as depicted in figs. 1 and 2, the supervisor 1 of expansion tube, arm 2, first block the 3, second blocking 4 and sealing blocking 5 and are PVC material and make, tube connector 6 is made for metal material, gasifying agent in arm by quality proportioning comprise respectively 45% nitroguanidine, the basic copper nitrate of 45%, the di-iron trioxide of 5% and 5% ammonium perchlorate, the length of every root expansion tube is 80cm, and diameter is 90mm, utilizes the blasting method of said structure expansion tube specifically to comprise the following steps:
A, one group of expansion tube is joined end to end fixing, connection is fixed by fixture 8 between former and later two adjacent expansion tubes, fixture 8 is provided with external screw thread for two ends, middle part is the pipe fitting of six prism structures, first blocking 3 of expansion tube and the second blocking 4 are provided with screwed hole, the two ends screw thread of fixture 8 blocks 4 and first the blocking 3 and be threaded of a rear expansion tube respectively with second of previous expansion tube, tube connector 6 is arranged in fixture 8 and two ends are communicated with two the expansion tube inside be connected respectively, the screwed hole being arranged in expansion tube second blocking 4 of end is closed, the expansion tube first being arranged in front end blocks connected tube 6 and passes, water or air can be filled in the supervisor of expansion tube, if filling air, then without the need to operation, it is air in expansion tube group after installing, if fill water as expanding blasting material, the plug on each expansion tube is then needed to back out, the perfusion of water is carried out by the tube connector of expansion tube 6 foremost, after often filling an expansion tube, plug to be screwed on sealing, until the supervisor of expansion tube is foremost filled, the external port of tube connector seals.
B, utilize drilling machine to punch at blow-up point, the diameter of punching is 90-100cm, and the degree of depth is 1-10m, and hole can hold end to end expansion tube group;
C, expansion tube group put into step b the hole beaten, and with cement by orifice sealing;
D, utilize remote controllers start electric starter 7, the gasifying agent ignited in arm 2, gasification agent temperature raises, gasifying agent is electrically activated the temperature heated in 40ms after device 7 ignites and is not less than 400 degrees Celsius, the arm 2 of high temperature is by the water of supervisor 1 inside or air high-temperature gasification and then expand, expansion tube generation explosion, finally realizes blow-up point mine blasting to carry out the object of exploiting.
Expansion tube in the utility model fills water or air as expanding blasting material in supervisor, instead of traditional explosive, preserve, personnel and the fund input of storage and management reduce greatly, and carry out examination & approval without the need to relevant departments to put on record, simplify the formality of use, and each part ratio due to expansion tube is easier to obtain, cost can decrease, owing to there is no combustible and explosive articles, at preparation blasting stage, the possibility met accident reduces greatly, effectively ensure that the safety of operating personnel, and this expansion tube can carry out Rapid Combination, multiple expansion tube is assembled into one group and carries out explosion, the power of explosion can be controlled by combination, in addition, compare traditional blasting method, due to the characteristic of water high-temperature gasification or air high-temperature expansion, when using this expansion tube to carry out mine blasting, explosion sound is relatively little, without slungshot phenomenon, without airborne dust, without Sasser and shock wave, and can not pernicious gas be produced, little to the ambient influnence near blow-up point, be suitable for applying in association area.
