Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical automation, and in particular relates to a perforating bullet clamping and rotating device. Background Art

[0002] In the domestic petroleum civil explosive equipment industry, perforating bullets are generally produced manually, and operators are directly exposed to the secondary explosives and main explosives. Both agents are flammable and explosive dangerous goods and have high friction and impact sensitivities, which pose a great safety hazard and threaten personal safety. Especially during the process of refilling or adding materials, the floating explosives produced enter the human body through the respiratory tract and skin, endangering the health of the operators.

[0003] The addition of explosives is an important step in the production process of perforating bullets. The existing method is to use a quantitative medicine cup to add explosives. When the addition is completed, the top of the perforating bullet needs to be piled up or the excess explosives need to be smoothed. At this time, a scraper is used manually. One hand fixes the scraper and the other hand rotates the perforating bullet to scrape off the excess explosives on the top, and then a brush is used to collect the floating explosives together. The above process has the following disadvantages:

[0004] 1) The labor intensity is high. Manual scraping and cleaning requires long-term training and a lot of experience. Workers cannot ensure the reliable and stable rotation of the perforating bullets. The scraping effects of workers with different experience vary.

[0005] 2) Explosives are dangerous goods. Workers are exposed to a relatively dangerous explosive dust environment for a long time. If the perforating bullet explodes due to misoperation or other reasons during the operation, the workers’ lives will be in danger.

[0006] How to design a perforating bullet clamping and rotating device to achieve automatic clamping and automatic rotation of the perforating bullet to facilitate the scraping of the perforating bullet has become a technical problem in this field. Utility Model Content

[0007] In view of the above technical problems, the utility model provides a perforating bullet clamping and rotating device, which can work automatically, and can control the rotation direction and speed of the perforating bullet on the positioning platform by rotating the motor. The perforating bullet can also be automatically positioned by controlling the clamping mechanism, so as to achieve uniform filling of the perforating bullet explosive, and can also automatically compact and smooth the raised explosive in conjunction with the top scraper.

[0008] The utility model solves the above problems through the following technical means:

[0029] The present invention will be described in detail below with reference to the accompanying drawings.

[0030] like Figures 1 to 8 As shown, the perforating bullet clamping and rotating device includes a positioning platform 1, a bearing seat 2, a clamping mechanism 3, a rotating shaft 4, a bearing seat 5, a transmission wheel 6, a conductive slip ring 7, a position sensor 8, a rotating motor 9, a driving wheel 10 and a transmission belt 11. In the figure, a positioning tube 101 is coaxially installed on the top of the positioning platform 1. The positioning tube 101 is used to install a perforating bullet 12. The bottom of the positioning tube 101 is a conical surface, and a center hole 102 is provided at the center position of the bottom. A detection rod 103 is movably installed in the center hole 102. The mechanism can quickly and automatically position the perforating bullet. The positioning platform structure is consistent with the external shape of the perforating bullet. When the perforating bullet is placed in the positioning platform, the perforating bullet can touch the top of the detection rod, and the bottom of the detection rod will touch the position sensor. At this time, the clamping mechanism automatically clamps the perforating bullet. Similarly, when the perforating bullet leaves the positioning platform, the detection rod is reset under the action of the reset spring. When the position sensor is not triggered, the clamping mechanism does not act.

[0031] It should be noted that the reset spring of the detection rod can be installed on the position sensor or inside the rotating shaft 4. In addition, the bottom of the positioning platform 1 is concave to form a circular cavity, and a plurality of square holes 104 are opened on the side wall of the circular cavity to facilitate the movement of the clamping claw 301.

[0032] In the figure, the load-bearing seat 2 is mounted on the top of the rotating shaft 4, and multiple load-bearing rods 201 are symmetrically installed on the bottom flange of the load-bearing seat 2. The top of the load-bearing rod 201 is used to fix and support the positioning platform 1. Specifically, the number of the load-bearing rods 201 is three, and the three load-bearing rods 201 are arranged on the bearing seat 5 at an interval of 120°.

[0033] In the figure, the clamping mechanism 3 is installed on the top of the load-bearing seat 2, and the clamping mechanism 3 is used to clamp the perforating bullet 12. Specifically, the clamping mechanism 3 includes a clamping claw 301, a guide cover 302 and a driving seat 303. It should be noted that the clamping claw 301 is an L-shaped structure, and an elastic claw head is provided at the top end of the L-shaped structure, and a guide block 304 is installed on the bottom crossbeam of the L-shaped structure; a limited long groove 305 is provided on the upper surface of the guide cover 302, and the limited long groove 305 is used to install the guide block 304 and limit the movement range of the guide block 304 to prevent the guide block 304 from excessively moving outward and away from the perforating bullet, and a sliding groove 306 is provided on the driving seat 303 to guide the guide block 304 to move forward and backward in a straight line.

[0034] In actual operation, an electromagnet is installed at the center of the driving seat 303, and the guide block 304 is made of a permanent magnet. By controlling the magnetic field of the electromagnet, the guide block 304 can be driven to move, so as to achieve the clamping claw 301 to approach or move away from the perforating charge 12. For example, when the top of the electromagnet is controlled to be the N pole, the position of the guide block 304 close to the center of the driving seat 303 is the S pole, and the two generate suction, driving the elastic claw head to move inward to clamp the perforating charge. Similarly, changing the electrode of the electromagnet can drive the elastic claw head to move outward away from the perforating charge.

[0035] In the figure, the bearing seat 5 is mounted on the middle part of the rotating shaft 4, and the outer wall of the bearing seat 5 is fixed on the box body 13; the transmission wheel 6 is mounted on the middle and lower part of the rotating shaft 4; the conductive slip ring 7 is mounted on the lower part of the rotating shaft 4; the position sensor 8 is installed at the bottom of the rotating shaft 4, the rotating shaft 4 is a hollow structure, and the detection rod 103 is arranged in the hollow structure. After the perforating bullet 12 is installed and placed in the positioning tube 101, it can touch the top of the detection rod 103, and the bottom of the detection rod 103 will touch the position sensor 8; the rotating motor 9 is installed on one side of the box body 13, and the driving wheel 10 is mounted on the rotating shaft of the rotating motor 9. The driving wheel 10 drives the transmission wheel and the rotating shaft 4 to rotate through the transmission belt 11.

[0036] In actual operation, the mechanism can control the rotation direction and speed of the perforating bullet on the positioning platform by rotating the motor. The uniform rotation can achieve two functions: when the perforating bullet is filled with explosives, reliable rotation can ensure uniform filling of explosives; when filling is completed, the scraper 14 is fixed on the top of the perforating bullet. By rotating, the scraper can automatically compact and smooth the raised explosives. The scraper 14 can also be designed as an automatic telescopic structure. The mechanism can work automatically, meet the requirements of explosion-proof and pyrotechnic industry, significantly improve production efficiency, realize fully automated work and separation of personnel and drugs.
