Abstract
The utility model relates to a self-destroying safety fuze for a mine rocket bomb, which relates to a detonating fuze device of a rocket bomb for mining explosion, particularly a rocket bomb which is suitable for dredging the blocking of a slide well in an explosion method. The self-destroying safety fuze for a mine rocket bomb is composed of a fuze shell body, a firing pin, a safety spring, a fuze seat, and a needle puncturing exploder. The self-destroying safety fuze for a mine rocket bomb has the advantages of high sensitivity and easy installation. The safety performance of the self-destroying safety fuze for a mine rocket bomb is reliable. The self-destroying safety fuze for a mine rocket bomb can ensure that a rocket bomb vertically falls more than 0.6 mm, and the rocket bomb can not be exploded. After the self-destroying safety fuze for a mine rocket bomb is used for the rocket bomb for a mine, the self-destroying safety fuze for a mine rocket bomb can ensure that a self-destroying rate of the rocket bomb after the rocket bomb is sent achieves 100 percent, and the treating danger of a dummy bomb of the rocket bomb for a mine is thoroughly solved.
Description
Technical field
Mine rocket projectile self-distroyable disposable safe initiation fuse, the special-purpose ignition fuse device of the rocket projectile that uses when relating to a kind of mining blasting, the rocket projectile that stops up especially for blasting procedure mediation drop shaft.
Background technology
In the mining process, often adopt the method for explosion.It is very important that employed mine rocket projectile has safe and reliable fuze mechanism.Be in the past adopt blasting cap and the paper big gun of issuing an order as the ignition fuse of mine rocket projectile, have shortcomings such as being difficult for installation, moisture-sensitive, sensitiveness are poor, poor safety performance.The patent No. be 94219958.8 and the patent No. to be 972022864.4 Chinese patent improve the fuse of mine rocket projectile, in use obtained good effect, improved the security performance of rocket projectile greatly.But still there are some problems in the mine rocket projectile fuse that above-mentioned two patents provide.As the duds rate is higher after launching, and operation easier is big in the assembling process, is difficult to guarantee the self-destruction rate of rocket projectile emission back 100%, also has potential safety hazard, has influenced operating personnel's the safety and the production safety in mine.
Summary of the invention
The purpose of this utility model is exactly the deficiency that exists at above-mentioned prior art, and a kind of high sensitive that has is provided, and is easy to assembling, and security performance is reliable, fully the mine rocket projectile destructing safety fuse of self-destruction.
The purpose of this utility model is achieved through the following technical solutions.
Mine rocket projectile self-distroyable disposable safe initiation fuse is characterized in that being made up of following parts:
One fuse housing-this fuse housing is the hollow body of an end band seam, and the other end has two safe pin-and-holes by its axle center;
One end of one striker-this striker is that cone, the other end are the cylinder that the inner surface of cylinder and fuse housing slips, the cylinder lower surface is concordant with fuse housing base, on the striker cylinder, have one with the corresponding pin-and-hole of crossing the axle center in housing safety pin hole site;
One relief spring-this relief spring is a spirality stage clip, and the one end is pressed on the cylindrical table top of striker, and is sleeved on outside the cone of striker;
One fuse seat-this fuse seat is three grades of stairstepping cylinders, its diameter largest portion is positioned at outside the fuse shell ends, the diameter parts of next is that the seam with fuse housing one end is connected together, its smallest diameter portion matches with guarantor's spring inside diameter, and in the embedding relief spring, fuse seat top has the primacord hole that always connects letter seat cylinder and pass through its axle center, have in the diameter end of cylinder minimum and to communicate with the primacord hole and flash hole that the axle center is identical with fuse seat axle center, have the stab detonator chamber coaxial in the flash hole lower end with flash hole;
One stab detonator, this stab detonator places stab detonator indoor;
One safety pin, this safety pin are the bar that an end has draw ring, and this safety pin runs through the safe pin-and-hole of fuse housing and the pin-and-hole on the striker cylinder.
Owing to adopted structure of the present utility model; make that it has high sensitive, is easy to install, safe and reliable advantage; guarantee not explode more than the rocket projectile vertical drop 0.6mm; after this fuse is used for mine rocket projectile; can guarantee that the self-destruction rate after the rocket projectile emission reaches 100%, thoroughly solve the danger of the duds processing of mine rocket projectile.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing mine rocket projectile destructing safety fuse of the present utility model is described further.
Mine rocket projectile self-distroyable disposable safe initiation fuse is characterized in that being made up of following parts: this fuse housing of fuse housing 1-is the hollow body of an end band seam, and the other end has two safe pin-and-holes by its axle center; One end of one this striker of striker 2-is that cone, the other end are the cylinder that the inner surface of cylinder and fuse housing slips, the cylinder lower surface is concordant with fuse housing base, on the striker cylinder, have one with the corresponding pin-and-hole of crossing the axle center in housing safety pin hole site; One this relief spring of relief spring 3-is a spirality stage clip, and the one end is pressed on the cylindrical table top of striker, and is sleeved on outside the cone of striker; One this fuse seat of fuse seat 5-is three grades of stairstepping cylinders, its diameter largest portion is positioned at outside the fuse shell ends, the diameter parts of next is that the seam with fuse housing one end is connected together, its smallest diameter portion matches with guarantor's spring inside diameter, and in the embedding relief spring, fuse seat top has the primacord hole 8 that always connects letter seat cylinder and pass through its axle center, have in the diameter end of cylinder minimum and to communicate with the primacord hole and flash hole 7 that the axle center is identical with fuse seat axle center, have the stab detonator chamber 4 coaxial in the flash hole lower end with flash hole; One stab detonator 6, this stab detonator places stab detonator indoor; One safety pin 9, this safety pin are the bar that an end has draw ring, and this safety pin passes through the safe pin-and-hole of sky fuse housing and the pin-and-hole on the striker cylinder.
When using the utility model, when rocket projectile in flight course, when running into barrier, removed the ignition fuse of safety pin, in moment flying speed vanishing, and striker is perverse to stab detonator, stab detonator will explode again can pass to primacord.Last primacord is ignited the explosive of dress in the rocket projectile again, thereby produces strong blast, plays with blasting procedure and handles the effect that drop shaft stops up.
Ignition fuse of the present utility model meets the normal requirement of using of mine rocket projectile fully, and susceptibility is very high.When no safety spring and safety pin, fuse vertically falls more than the 0.5m, and blast can reach 100%, and after installing relief spring additional, fuse vertically falls more than the 1.0m, and rate of explosion can reach 100%.Ignition fuse is behind the installation insurance spring, and when safety pin had been removed, the vertical drop height of fuse was during less than 0.7m, and the rate of explosion of fuse is zero.
Ignition fuse of the present utility model has the performance of protection against the tide, waterproof, processes very convenient, safety, and susceptibility is very high.In case after the mine rocket projectile emission, when its blast self-destruction rate reaches 100%.If not lift-off after the rocket projectile emission because ignition fuse has the effect of protecting thrifty spring, can be removed this device by hand under very safe state.More meet the actual requirement of bargh.
