Abstract
The invention provides a kind of combined double-explosive-source explosive post, it is by the powder column housing, sealing gland, sealing gland is sealed in explosive among the powder column housing, the lower end of powder column housing is provided with birdsmouth, powder column housing lower end is a blind end, blind end is provided with the blind hole of detonating of indent, the upper end of birdsmouth is closely linked by ratchet structure and blind end, the upper end that is positioned at birdsmouth also is provided with the clue perforation of detonating, the upper end of powder column housing is provided with the opening undergauge and accepts head, the opening undergauge is accepted the cylindrical of head and the interior circle of the birdsmouth of adjacent powder column housings close end matches, and be connected by connecting locking device, the end that the opening undergauge is accepted head closely is connected with the cylindrical of sealing gland by sealing ring, and the awns hole of detonating on the sealing gland is relative with the blind hole of detonating of powder column housings close end.This combined double-explosive-source explosive post is compared with prior art, have water-stop reasonable in design, simple in structure, anti-, safe and reliable, be easy to characteristics such as maintenance, extensively promote the use of, thereby, have good value for applications.
Description
1, technical field
The present invention relates to a kind of explosive production and processing technology, specifically a kind of combined double-explosive-source explosive post.
2, background technology
The plastics explosive-source explosive post of prior art existing deficiency in actual application is: complex process, consumption of raw materials be big, it is inconvenient to use, water repelling property difference and poor safety performance or the like.Such as application number is No. 98211491.5, name is called " detachable boosting type explosive-source explosive post ", its gland adopts the heat seal mode fixedly connected, being connected between cartridge case and the cartridge case adopted the connector of the two screw threads of band, gland connects by the heat seal mode, except bothersome, the cartridge case of filling explosive uses electric heater that gland is heated heat seal and handles, and just there is certain risk in itself.Adopt connector to carry out connection between the cartridge case except the consumption of raw materials that increases connector, the connector that adds is that transportation or construction also bring a lot of inconvenience all can for user's use.
3, summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming, provide a kind of reasonable in design, technology simple, easy to make, water resistance is good, has the combined double-explosive-source explosive post of two fire points.
Technical scheme of the present invention realizes in the following manner, this double-explosive-source explosive post is by the powder column housing, sealing gland is formed, sealing gland is sealed in explosive among the powder column housing, the upper end of powder column housing is provided with birdsmouth, powder column housing upper end is a blind end, blind end is provided with the blind hole of detonating of indent, the upper end of birdsmouth is closely linked by ratchet structure and blind end, the upper end that is positioned at birdsmouth also is provided with the clue perforation of detonating, the upper end of powder column housing is provided with the opening undergauge and accepts head, the opening undergauge is accepted the cylindrical of head and the interior circle of the birdsmouth of adjacent powder column housings close end matches, and be connected by connecting locking device, the end that the opening undergauge is accepted head closely is connected by the cylindrical of sealing ring with sealing gland 5, and the awns hole of detonating on the sealing gland is relative with the blind hole of detonating of powder column housings close end.
Advantage of the present invention is: according to the natural characteristic of material, adopt the design of sealing ring tension structure, the gland nature is connected with the powder column housing seal, avoided outer thermal weld, i.e. saving of work and time, also safety.In order to improve the security of detonating, avoid " miso-fire " in the two blind holes of detonating of the two ends up and down of powder column housing design, four detonators can be set on the tie point of per two powder columns lay a little, working security improves greatly.In being connected on the compound mode of cartridge case and cartridge case, adopted integrated design, a cartridge case can directly be connected with another cartridge case head and the tail, has saved intermediate connector, has promptly saved material consumption, has made things convenient for preservation, transportation and construction again.Thereby, powder column of the present invention compare with prior art have simple in structure, reasonable in design, save characteristics such as material, good seal performance, raising work efficiency, safe and reliable, easy storage transportation and convenient construction.
4, description of drawings
Fig. 1 is the birdsmouth of combined double-explosive-source explosive post and accepts head and adopt the structural representation that is threaded;
Mark in the accompanying drawing is represented respectively; Birdsmouth 1; Ratchet structure 2; Housings close end 3; The blind hole 4 of detonating; Sealing gland 5; Screw thread 6; The opening undergauge accepts 7; Powder column housing 8; Detonating cord perforation 9.
5, the specific embodiment
Do following detailed description the in detail below in conjunction with 1 pair of combined double-explosive-source explosive post of the present invention of accompanying drawing.
As shown in Figure 1, combined double-explosive-source explosive post of the present invention is by powder column housing 8, sealing gland 5 is formed, sealing gland 5 is sealed in explosive among the powder column housing 8, the lower end of powder column housing 8 is provided with birdsmouth 1, powder column housing 8 lower ends are blind end 3, blind end 3 is provided with the blind hole 4 of detonating of indent, the upper end of birdsmouth 1 is closely linked by ratchet structure 2 and blind end 3, the upper end that is positioned at birdsmouth 1 also is provided with the clue perforation 9 of detonating, the upper end of powder column housing 8 is provided with the opening undergauge and accepts 7, the interior circle that the opening undergauge is accepted the birdsmouth 1 of 7 cylindrical and adjacent powder column housing 8 closed ends matches, and be connected by connecting locking device, the opening undergauge is accepted an end of 7 and closely is connected by the cylindrical of sealing ring 10 with sealing gland 5, and the awns hole 4 of detonating on the sealing gland 5 is relative with the blind hole 4 of detonating of powder column housing 8 blind ends 3.
Opening accept 7 and birdsmouth 1 between the connection locking device be screw thread 6.
Be provided with bonding agent between the lower end of birdsmouth 1 and powder column housing 8 closed ends 3.
The processing of powder column housing 8, sealing gland 5 is all by general blowing or Shooting Technique processing and manufacturing.
Use of the present invention is very simple and convenient, during use, detonating capsule is placed in respectively in the blind hole of detonating of gland and powder column housings close end, detonating cord draws the powder column housing from the perforation of birdsmouth and the powder column housing links together by screw thread or ratchet syndeton by accepting head and birdsmouth.Because every each powder column housing has two blind holes of detonating, so can lay two detonators simultaneously, can avoid the generation of miso-fire so fully, has promptly made things convenient for construction, has improved safety of construction again.In addition owing to do not need the other connector that carries, the powder column housing thereby, reduced transportation and keeping cost, made things convenient for workmen's constructing operation.
