[0039] In this embodiment, as Figure 1 and Figure 2 shown, an explosive disposal device for public safety includes an explosion-proof tank body 1, on which an opening and closing assembly 2 is installed. The opening and closing assembly 2 reduces the upward impact force generated by the explosion of the explosive. The opening and closing assembly 2 includes a closing member 21, a connecting pin 22, and a buffer member 23. The closing member 21 uses a spherical structure to close the top opening of the explosion-proof tank body 1. The closing member 21 is slidably connected to the chute of the explosion-proof tank body 1 through the connecting pin 22. The connecting pin 22 is threadedly connected to the closing member 21. The buffer member 23 reduces the impact force of the shock wave generated by the explosion on the closing member 21.
[0040] Thus, the explosive is stored in the cavity of the explosion-proof tank body 1, and then the closing member 21 is inserted into the top of the explosion-proof tank body 1. When the closing member 21 is completely fitted to the explosion-proof tank body 1, the connecting pin 22 is rotated and inserted between the chute on the side wall of the explosion-proof tank body 1 and the buffer member 23. When the explosive explodes, the shock wave generated by the explosion drives the closing member 21 to move upward. The closing member 21 drives the connecting pin 22 to move. The upward moving connecting pin 22 causes the buffer member 23 to work, thereby reducing the impact force of the explosion-generated impact on the closing member 21.
[0041] Furthermore, the explosion-proof tank body 1 is used to store the explosive. The closing member 21 closes the opening at the top of the explosion-proof tank body 1. The connecting pin 22 is inserted into the chute of the explosion-proof tank body 1 to restrict the use position of the closing member 21. There are two connecting pins 22.
[0042] In some embodiments, as Figure 1 and Figure 3As shown, the closure member 21 includes a top cover 211 and a sphere 212. The top cover 211 is installed on the top of the explosion-proof tank body 1, and the sphere 212 is fixedly connected to the center position of the top cover 211. The top cover 211 drives the sphere 212 to be embedded into the opening at the top of the explosion-proof tank body 1 for closing, and the sphere 212 is in spherical contact with the shock wave generated by the explosion.
[0043] Furthermore, the top cover 211 is sleeved on the outer wall of the explosion-proof tank body 1, and the sphere 212 is clamped at the top of the inner cylinder 11. When the sphere 212 is completely fitted with the inner cylinder 11, the lowest end of the top cover 211 is located at one-third of the outer wall of the explosion-proof tank body 1. The setting of the sphere 212 enables it to be in arc contact with the shock wave, having a certain buffering effect.
[0044] In some embodiments, as Figure 2 shown, the buffer member 23 includes a cylinder 231, a top rod 232, a clamping plate 233 and an elastic member 234. The cylinder 231 is fixedly connected to the chute of the explosion-proof tank body 1, the top rod 232 is inserted into the cylinder 231, the clamping plate 233 is fixedly connected to the bottom end of the top rod 232, and the elastic member 234 is fixedly connected to the top end of the top rod 232. The elastic member 234 is arranged in the cavity of the cylinder 231. When the connecting pin 22 moves upward, it drives the clamping plate 233 and the top rod 232 to move upward, thereby compressing the elastic member 234, and the impact force received by the sphere 212 is weakened by the compression of the elastic member 234.
[0045] Furthermore, two cylinders 231 are symmetrically distributed on both sides of the explosion-proof tank body 1, the top rod 232 moves up and down in the cylinder 231, the clamping plate 233 is processed into a semi-circular arc shape. When the top cover 211 closes the explosion-proof tank body 1, the rotating connecting pin 22 is inserted into the clamping plate 233, and the elastic member 234 is a compression spring.
[0046] In some embodiments, as Figure 3 shown, an inner cylinder 11 is inserted into the explosion-proof tank body 1, and a slot plate 12 is fixedly connected to the inner cylinder 11. The slot plate 12 is inserted into the chute of the explosion-proof tank body 1.
[0047] Furthermore, two slot plates 12 are fixedly connected to the inner cylinder 11, and the inner cylinder 11 is connected in a detachable manner for easy replacement.
[0048] In some embodiments, as Figure 4As shown in the figure, a traction assembly 3 is installed on the explosion-proof tank body 1. The traction assembly 3 drives the sphere 212 to move. The traction assembly 3 includes a bearing base 31, a mounting frame 32, a sliding seat 33, a connecting member 34, and a driving member 35. The bearing base 31 is fixedly connected to the explosion-proof tank body 1. The mounting frame 32 is fixedly connected to the bearing base 31. The sliding seat 33 is slidably connected in the chute of the mounting frame 32. When the sliding seat 33 moves in the mounting frame 32, it drives the sphere 212 to move together through the connecting member 34. The driving member 35 provides power for the sliding seat 33 to move in the chute of the mounting frame 32.
[0049] Furthermore, a through groove for installing the explosion-proof tank body 1 is processed in the bearing base 31. The bearing base 31 plays a supporting role for the overall mechanism. A chute is processed in the mounting frame 32. The sliding seat 33 moves vertically in the chute of the mounting frame 32. The connecting member 34 is used to connect the sphere 212.
[0050] In some embodiments, as Figure 1 and Figure 6 shown, the connecting member 34 includes a strip plate 341, a rope 342, and a connecting seat 343. The strip plate 341 is fixedly connected to the sliding seat 33. The connecting seat 343 is connected to the strip plate 341 through the rope 342. The connecting seat 343 is fixedly connected to the top of the sphere 212.
[0051] Furthermore, the strip plate 341 moves with the sliding seat 33. The rope 342 connects the connecting seat 343 and the strip plate 341. The setting of the rope 342 facilitates bending.
[0052] In some embodiments, as Figure 1 and Figure 4 shown, the driving member 35 includes a transmission shaft 351, a sliding sleeve 352, and a motor 353. The transmission shaft 351 is rotatably connected to the mounting frame 32 through a bearing. The sliding sleeve 352 is threadedly connected to the transmission shaft 351. The sliding sleeve 352 is fixedly connected in the sliding seat 33. The output end of the motor 353 is fixedly connected to the top end of the transmission shaft 351.
[0053] Furthermore, the motor 353 adopts a servo motor. The motor 353 is connected to the transmission shaft 351 through a coupling. The setting of the sliding sleeve 352 is used to drive the sliding seat 33 to move.
[0054] In some embodiments, as Figure 1 and Figure 5As shown, a braking component 4 is installed in the bearing base 31. The braking component 4 restricts the movement of the bearing base 31. The braking component 4 includes a threaded barrel 41, a screw rod 42, a handwheel 43 and a fixed disk 44. The threaded barrel 41 is fixedly connected to the bearing base 31. The screw rod 42 is threadedly connected in the threaded barrel 41. The handwheel 43 is fixedly connected to the top end of the screw rod 42. The fixed disk 44 is fixedly connected to the bottom end of the screw rod 42. When the screw rod 42 moves downward in the threaded barrel 41, it drives the fixed disk 44 to closely fit with the ground, thereby braking the bearing base 31.
[0055] Further, the threaded barrel 41 is machined with internal threads, the outer wall of the screw rod 42 is machined with external threads. The handwheel 43 is provided for rotating the screw rod 42. The fixed disk 44 is machined into a circular shape for pressing against the ground. When the fixed disk 44 presses against the ground, the stability of the bearing base 31 is increased.
[0056] In some embodiments, such as Figure 1 and Figure 5 As shown, a grooved plate 441 is fixedly connected to the bottom of the fixed disk 44. The grooved plate 441 increases the friction between the fixed disk 44 and the ground.
[0057] Further, the grooved plate 441 is machined with strip-shaped grooves. The setting of the strip-shaped grooves makes the fixed disk 44 and the ground more stable.
[0058] In some embodiments, such as Figure 5 As shown, universal wheels 311 are installed on the bearing base 31. The universal wheels 311 drive the bearing base 31 to move.
[0059] Further, three universal wheels 311 are provided. The setting of the universal wheels 311 facilitates moving the overall mechanism to the corresponding position.
[0060] The working principle of the present application will be described below with a relatively optimal embodiment:
[0061] The inner cylinder 11 is inserted into the interior of the explosion-proof tank body 1 through the clamping groove plate 12. Subsequently, explosives are stored in the cavity of the inner cylinder 11 in the explosion-proof tank body 1. Then, the motor 353 is started. The motor 353 drives the transmission shaft 351 to rotate in the mounting frame 32 through the coupling. Furthermore, the sliding sleeve 352 on the transmission shaft 351 drives the sliding seat 33 to move downward in the sliding groove of the mounting frame 32. The sphere 212 is connected to the strip plate 341 through the connecting seat 343, the rope 342. Thus, when the strip plate 341 moves downward with the sliding seat 33, the sphere 212 is positioned at the top of the inner cylinder 11, and the top cover 211 seals the top of the explosion-proof tank body 1. Rotate the connecting pin 22 in the top cover 211, and the connecting pin 22 is inserted into the bottom of the clamping plate 233. When the explosives explode, the shock wave acts on the sphere 212 to drive the top cover 211 to move upward. The top cover 211 drives the connecting pin 22 to move upward. At the same time, the connecting pin 22 drives the ejector rod 232 to move upward in the cylinder 231 through the clamping plate 233. The ejector rod 232 compresses the elastic member 234 in the cylinder 231. The deformation of the elastic member 234 is used to slow down the impact force received by the sphere 212. Rotate the handwheel 43 to rotate the screw rod 42, and the screw rod 42 moves downward in the threaded cylinder 41. Furthermore, the fixed disk 44 and the grooved plate 441 are pressed against the ground to realize the braking of the overall mechanism.
