The invention also provides a separation method of the dangerous initiating explosive device assembly, which adopts the separation device of the dangerous initiating explosive device assembly, and as shown in figure 1, the separation method comprises the following steps:
before the initiating explosive device is formally disassembled, an operator needs to carefully check the grade of a workshop on the operation site, and a hygrothermograph is used for detecting the temperature and the relative humidity in the workshop, wherein the temperature is confirmed to be 0-40 ℃, and the relative humidity is 20-80%; the operation can not be carried out in thunderstorm days.
the loaded state of the initiating explosive device is carefully checked, and the principle of reverse disassembly of the assembly sequence is followed.
before the initiating explosive device is disassembled, static electricity is released, an anti-static bracelet is worn, and the product is connected with a ground wire. When the dangerous initiating explosive device assembly is disassembled, the electric connector of the initiator is disconnected, the short sealing plug is installed, and then the dangerous initiating explosive device assembly is disassembled; the removed initiating explosive devices are stored in a special initiating explosive device storage warehouse in time.
hoisting the dangerous initiating explosive device assembly onto the antistatic workbench 1, and connecting the lifting lugs 6 on the outer surface of the dangerous initiating explosive device body 2 with the pull rods 3 at two ends of the first arc-shaped fixed seat 4 and the second arc-shaped fixed seat 5 so as to fix the dangerous initiating explosive device assembly;
firstly, a first set screw is inserted into the first threaded hole 18, so that the first fastening spiral ring 21 and the first initiation chamber 22 are relatively fixed; then the clamping ring 11 is embedded on the outer surface of the first fastening spiral ring, and the first bulge 33 of the clamping ring 11 corresponds to the first clamping groove 12 in position; the second protrusion is embedded with the second slot 13, the third protrusion is embedded with the third slot 14, the fourth protrusion is embedded with the fourth slot 15, the initiation chamber fixing mechanism can pull the first fastening screw ring 21 to prevent rotation, and the initiation chamber fixing mechanism is fixed relative to the first fastening screw ring 21, so that the initiation chamber fixing mechanism is fixed relative to the first fastening screw ring 21 and the first initiation chamber 22, and fig. 3 and fig. 4 are shown.
firstly, removing the second set screw and the third set screw, then applying thrust to the wrenching ring 27 by using the wrench force application rod 26 to enable the first wrenching teeth 28 to be embedded into the first wrenching holes 16, and the second wrenching teeth to be embedded into the second wrenching holes 17, and simultaneously ensuring that the central line of the wrenching ring 27 is superposed with the central line of the first crimping screw ring 23; furthermore, the wrench ring 27 is rotated by rotating the wrench force applying rod 26 to apply a rotational force to the wrench ring 27, so that the wrench ring 27 rotates and unscrews the first crimp ring 23.
In the step 6, in the process of unscrewing the first crimping screw ring 23, the wrenching ring 27 is always kept attached to the first crimping screw ring 23, which not only can prevent the first wrenching teeth 28 and the second wrenching teeth from being disengaged from the corresponding wrenching holes, but also the first crimping screw ring 23 is uniformly stressed; the second fixing block 25 is rigidly connected with the dangerous initiating explosive device body supporting seat through the second upright post 24, so that the wrench force applying rod 26 can be supported, the wrenching ring 27 is ensured not to generate a wrenching bending moment due to deflection in the wrenching process, the direction of the rotating moment applied to the first crimping screw ring 23 by the first wrenching teeth 28 and the second wrenching teeth is controlled to be in the same direction as the rotating direction, and excessive axial component force is not generated. The wrench force application rod 26 is slowly rotated to finally unscrew the first crimp ring 23.
And 7, decomposing the first initiator 34 and the dangerous initiating explosive device body 2.
Firstly, the initiation chamber fixing mechanism and the crimping screw ring dismounting mechanism move to the lower part of a second initiator 35 by sliding the sliding block 7 along the first short rod 31 and the second short rod 32; then, checking whether the thread locking glue sealant permeates into the installation gap between the first initiator 34 and the first initiation chamber 22; if the sealing agent of the non-threaded locking glue permeates or permeates a little, the plug of the first initiator 34 is pinched by fingers, and the plug is slowly shaken up and down and pulled outwards, if the first initiator 34 shakes, the plug of the initiator is directly grabbed by the fingers and is slowly pulled out; if the inspection shows that the thread locking sealant permeates more, the first initiator 34 cannot be shaken by fingers, a feeler gauge with corresponding thickness is selected according to the size of the gap, the thread locking sealant in the gap is slowly pulled and removed back and forth with proper force until the first initiator 34 can be shaken by the fingers, and the initiator plug is grasped by the fingers and slowly pulled out; the detached first initiator 34 and the initiating explosive device body are respectively put into a special packaging box for isolated storage.
It should be noted that, when the second initiator 35 needs to be disassembled, the safe disassembling process from step 1 to step 6 is repeated.
It should be noted that the process of detaching, moving and installing the trigger chamber fixing mechanism is as follows: because the first fixing block 10 is in threaded connection with the snap ring 11, when the second initiator 35 needs to be disassembled, the snap ring 11 and the first fixing block 10 are disassembled first, then the snap ring 11 is disassembled from the first fastening spiral ring 10 and clamped on the second fastening spiral ring of the second initiator 35, the first upright post 8, the fixing rod 9 and the first fixing block 10 slide to the position below the second initiator 35 along the sliding block, and the connecting portion of the snap ring 11 is connected with the first fixing block 10.
The disassembly, movement and installation processes of the compression joint spiral ring disassembly mechanism are as follows: after the first crimp ring 23 is screwed out through the wrench force applying rod 26 and the wrenching ring 27, the whole crimp ring dismounting mechanism is moved to the lower side of the second initiator 35 along the slide block, the wrench force applying rod 26 is screwed, the first wrenching teeth 28 and the second wrenching teeth are inserted into the corresponding wrenching holes, and the wrench force applying rod 26 is rotated, so that dismounting of the second crimp ring can be carried out.
After the second initiator 35 is completely disassembled, the initiation chamber fixing mechanism and the crimping screw ring disassembling mechanism are disassembled from the dangerous initiating explosive device body supporting seat.
