By means of the initiator detachment mechanism, a safe separation of the first initiator 34 from the hazardous initiating explosive device body 2 is achieved.
It should be noted that the process of detaching the second initiator 35 is the same as the process of detaching the first initiator 34, and is implemented by using the above-mentioned separation tool.
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, as shown in figure 1, and comprises the following steps:
step 1, checking the working environment;
before formally dismantling the initiating explosive device, operators should carefully check the grade of the factory building on the operation site, detect the temperature and the relative humidity in the factory building by using a hygrothermograph, and confirm that the temperature is 0-40 ℃ and the relative humidity is 20-80%; the operation cannot be performed in the rainy days.
Step 2, checking the loading state of the dangerous initiating explosive device assembly;
the state of the loaded initiating explosive devices is carefully checked, following the reverse disassembly principle of the assembly sequence.
Step 3, checking notice of disassembling the dangerous initiating explosive device assembly;
before the initiating explosive device is disassembled, static electricity is released, the anti-static bracelet is worn, and the product is grounded. When the dangerous initiating explosive device assembly is disassembled, the electric connector of the initiator is disconnected, a short-seal plug is installed, and then the dangerous initiating explosive device assembly is disassembled; the removed initiating explosive devices should be stored in a special initiating explosive device storage warehouse in time.
Step 4, fixing the dangerous initiating explosive device assembly;
the dangerous initiating explosive device assembly is hoisted to the antistatic workbench 1, and the lifting lug 6 on the outer surface of the dangerous initiating explosive device body 2 is connected with the pull rods 3 at the two ends of the first circular arc-shaped fixing seat 4 and the second circular arc-shaped fixing seat 5, so that the dangerous initiating explosive device assembly is fixed.
Step 5, fixing the dangerous initiating explosive device body 2 and the first initiating chamber 22 by using the initiating chamber fixing mechanism;
first, a first set screw is inserted into the first threaded hole 18 to realize the relative fixation of the first fastening spiral ring 21 and the first initiation chamber 22; 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 bulge is embedded with the second clamping groove 13, the third bulge is embedded with the third clamping groove 14, the fourth bulge is embedded with the fourth clamping groove 15, and the initiation chamber fixing mechanism can pull the first fastening spiral ring 21 to be not rotated, so that the initiation chamber fixing mechanism and the first fastening spiral ring 21 are relatively fixed, and the initiation chamber fixing mechanism and the first fastening spiral ring 21 and the first initiation chamber 22 are relatively fixed, as shown in fig. 3 and fig. 4.
Step 6, removing the crimping screw of the first initiator 34 by utilizing a crimping screw removing mechanism;
removing the second set screw and the third set screw, and then applying thrust to the screwing ring 27 by using the spanner application rod 26 to enable the first screwing teeth 28 to be embedded into the first screwing holes 16, and enabling the second screwing teeth to be embedded into the second screwing holes 17, so as to ensure that the center line of the screwing ring 27 is coincident with the center line of the first compression joint spiral ring 23; further, the wrench force applying lever 26 is rotated 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 press-connection spiral ring 23, the screwing ring 27 is always attached to the first press-connection spiral ring 23, so that the first screwing teeth 28 and the second screwing teeth can be prevented from being separated from the corresponding screwing holes, and the stress of the first press-connection spiral ring 23 is uniform; 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 spanner force application rod 26 can be supported, the spanner bending moment generated by deflection of the spanner ring 27 in the spanner process is avoided, the direction of the rotation moment applied to the first compression joint spiral ring 23 by the first spanner tooth 28 and the second spanner tooth is controlled to be in the same direction as the rotation direction, and excessive axial component force is not generated. The wrench force applying rod 26 is slowly rotated, and finally the first press-fit spiral ring 23 is unscrewed.
Step 7, the first initiator 34 and the dangerous initiating explosive device body 2 are decomposed.
The initiation chamber fixing mechanism and the crimping screw ring detaching mechanism are moved to the lower part of the second initiator 35 by sliding the slide block 7 along the first short rod 31 and the second short rod 32; then, checking whether the screw locking glue sealant is penetrated into the mounting gap between the first initiator 34 and the first initiator chamber 22; if the sealant without the thread locking glue is infiltrated or infiltrated little, the first initiator 34 plug is pinched by fingers, and the first initiator 34 plug is slowly rocked up and down and pulled outwards, if the first initiator 34 is rocked, the first initiator plug is directly grabbed by fingers, and is slowly pulled out; if the inspection finds that the penetration of the screw locking sealant is more, the first initiator 34 cannot be shaken by fingers, a corresponding thickness gauge is selected according to the size of the gap, and the screw locking sealant in the gap is slowly withdrawn and removed with proper strength until the first initiator 34 can be shaken by fingers, and then the initiator plug is grasped by fingers, so that the screw locking sealant is slowly withdrawn; the first initiator 34 and the initiating explosive device body which are detached are respectively put into special packaging boxes for isolation storage.
When the second initiator 35 needs to be detached, the safe detachment process of steps 1 to 6 is repeated.
It should be noted that the process of detaching, moving and installing the induction chamber fixing mechanism is as follows: because the first fixing block 10 is connected with the clamping ring 11 through threads, when the second initiator 35 needs to be disassembled, the clamping ring 11 is firstly disassembled from the first fixing block 10, then the clamping 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 lower part of the second initiator 35 along the sliding block, and the connecting part of the clamping ring 11 is connected with the first fixing block 10.
The disassembly, movement and installation processes of the crimping spiral ring disassembly mechanism are as follows: after the first crimping screw 23 is unscrewed through the wrench force applying rod 26 and the wrench ring 27, the whole crimping screw dismounting mechanism is moved to the lower part of the second initiator 35 along the sliding block, the wrench force applying rod 26 is screwed, the first wrench tooth 28 and the second wrench tooth are inserted into the corresponding wrench hole, and the wrench force applying rod 26 is rotated to dismount the second crimping screw.
When the second initiator 35 is detached, the initiation chamber fixing mechanism and the crimping screw ring detaching mechanism are detached from the dangerous initiating explosive device body supporting seat.
The present invention is not limited to the above-mentioned embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
