Description

Technical Field

[0001] The invention relates to an automatic disassembly and assembly fixture for a container lock pin, belonging to the technical field of special equipment for containers. Background Art

[0002] A container is a large cargo container with a certain strength, rigidity, and specifications, designed for turnover. With economic development, the port transportation industry has also gradually flourished, and containers are becoming more and more widely used. Safety is of paramount importance in container shipping. If a container carrying more than ten tons of cargo slips or rolls off the vehicle, it will cause immeasurable damage to human life and property safety. Therefore, during the process of shipping containers at sea, the upper and lower containers often slip or tip over due to wind or minor collisions. For transportation safety, the upper and lower containers must be connected with special locking pins to ensure that the upper and lower containers are relatively fixed during navigation. When the container is transported to the destination for unloading, the locking pins will also be hoisted onto the truck along with the container. When the truck leaves the port, staff need to manually remove and collect the locking pins on the container.

[0003] With the development of the economy, there are higher requirements for the operating efficiency of ports. Now, automated control is also widely used in the lifting and transportation operations of containers to improve operational efficiency. However, the removal of the locking pins on the containers always requires manual operation. This is because the locking pin structures used by different ships are different. According to incomplete statistics, there are hundreds of commonly used container locking pins on the market. Each locking pin has a different structure and a different unlocking method. Therefore, it is difficult to remove the locking pins through automated equipment. There are also some clamps that can realize automatic disassembly and assembly of locking pins, but they can only be applied to the disassembly and assembly of a very few types of locking pins. The scope of application is limited and cannot be applied to actual operation processes. Therefore, there is an urgent need for a clamp that can automatically disassemble and assemble most locking pins to realize the automated operation of locking pin disassembly and assembly.

[0065] The working principle of a container lock pin automatic disassembly and assembly fixture is:

[0066] The automatic disassembly and assembly fixture of the container lock pin is connected to the robotic arm through the base 4. When the lock pin of the container is disassembled, the robotic arm drives the automatic disassembly and assembly fixture of the container lock pin to move to the bottom of the lock pin, and the robotic arm aligns the center of the lock pin clamping mechanism 1 with the center of the lock pin, and then lifts the automatic disassembly and assembly fixture of the container lock pin upward so that the lock pin clamping mechanism 1 is flush with the middle position of the lock pin, and the longitudinal moving component 10 in the lock pin clamping mechanism 1 runs, and the drive motor 16 is started. The drive motor 16 drives the two bidirectional screw rods 14 to rotate synchronously in opposite directions through the drive gear 118, the transmission gear 119 and the driven gear 117. Since the threads on the two bidirectional screw rods 14 are in opposite directions, the longitudinal slide on the bidirectional screw rod 14 moves in opposite directions. 12 moves in the same direction under the action of the two bidirectional screw rods 14. The rotation of the bidirectional screw rods 14 drives the two longitudinal slides 12 to drive the lock pin clamping assemblies 11 to move toward each other until they move to both sides of the lock pin. Then the lock pin clamping assembly 11 is operated, and the bidirectional motor 17 in the lock pin clamping assembly 11 is started. The output shaft of the bidirectional motor 17 drives the first screw rod 19 to rotate. Since the second clamping arm 114 is threadedly connected to the first screw rod 19, the second clamping arm 114 moves toward the first clamping arm 115 under the drive of the first screw rod 19. When the second clamping arm 114 moves, the second transmission tooth 113 on the side of the second clamping arm 114 drives the first transmission tooth 110 to move through the gear 112, thereby When the holding arm 115 moves, the first clamping arm 115 moves synchronously toward the second clamping arm 114 under the action of the third connecting rod 18, and the first clamping arm 115 and the second clamping arm 114 move synchronously toward each other to clamp the middle part of the lock pin. In the process of the lock pin clamping mechanism clamping the lock pin, due to different lock pin structures, some lock pins have different thicknesses on both sides, or some lock pins have asymmetric structures on both sides, when the lock pin clamping assembly 11 clamps the above-mentioned lock pin, a certain misalignment needs to be generated between the two lock pin clamping assemblies 11 in order to clamp the lock pin. Therefore, in the process of clamping the above-mentioned lock pin, the lock pin clamping assembly 11 is subjected to the reaction of the lock pin, and the lock pin clamping assembly 11 generates a lateral movement under the action of the reaction force of the lock pin. In the small amplitude position, the guide rod 125 on the bottom surface of the clamping arm mounting seat 15 in the lock pin clamping assembly 11 moves with the lock pin clamping assembly 11, and a spring 124 is provided between the fixed block 121 in the middle of the guide rod 125 and the connecting block 127 on the longitudinal slide 12. The compression of the spring 124 enables the guide rod 125 to perform a small amplitude lateral displacement, so that the lock pin clamping assembly 11 can perform a small amplitude position to adapt to the clamping of the lock pin. After the clamping is completed, the guide rod 125 is reset by the action of the spring 124, thereby resetting the two groups of lock pin clamping assemblies 11. The above structure effectively realizes the small amplitude lateral adjustment of the lock pin clamping assembly 11 during the clamping process, thereby expanding the application range of the lock pin clamping assembly 11 and improving the stability of the clamping;

[0067] The unlocking of most lock pins is to drive the upper lock pin to the unlocking position by rotating the lock core at the bottom so that the lock pin can be removed, and the locking mechanism of some lock pins is set on one side of the lock core. Therefore, when disassembling and assembling the above-mentioned type of lock pin, after the lock pin clamping mechanism 1 clamps the lock pin body, the second unlocking mechanism 3 is started, and the center of the circle of the annular bracket 34 in the second unlocking mechanism 3 is aligned with the center of the lock pin, and then the automatic disassembly and assembly fixture of the container lock pin moves upward, so that the lock pin enters the middle of the annular bracket 34 in the clamping mechanism. After the unlocking mechanism moves into place, the scanning device scans the structure of the lock pin, determines the type of lock pin and calculates the unlocking method of the lock pin, and then the lifting drive component 36 in the unlocking mechanism is started, the lifting drive motor 35 is started, and the lifting drive component 36 is started. The lowering drive motor 35 drives the second ring gear 39 to rotate through the cooperation of the lifting drive gear 318 and the lifting transmission gear 319. The second ring gear 39 is meshed with the lifting driven gear 312, thereby driving the three screw rods 311 to rotate synchronously at the same time through the lifting driven gear 312. Since the lifting seat 33 is threadedly connected to the screw rod 311 through the connecting part 310, the lifting seat 33 is driven to move up and down. The movement of the lifting seat 33 drives the second unlocking component 321 to move upward, so that the upper end of the rocker arm 322 in the second unlocking component 321 is flush with the surface of the lock core below the lock pin, and then the rocker arm driving component 323 in the clamping mechanism is started, and the motor 327 in the rocker arm driving component 323 drives the fan-shaped ratchet 3212 to rotate toward the inside of the annular bracket 34. The fourth connecting rod 3209 is used to connect the connecting portion 328 of the second rotating shaft 326 above the fan-shaped ratchet 3212, and a cam mechanism is formed between the fan-shaped ratchet 3212, the fourth connecting rod 3209 and the connecting rod 328. The rotation of the fan-shaped ratchet 3212 drives the second rotating shaft 326 to rotate counterclockwise, and the second rotating shaft 326 in the two clamping assemblies rotate synchronously. The rocker arm 322 connected to the second rotating shaft 326 moves toward the center of the circle of the annular bracket 34 under the drive of the second rotating shaft 326. The working parts 3213 of the two rocker arms 322 contact the surface of the lock core below the lock pin to clamp the lock core. Then the rotation drive assembly 320 in the unlocking mechanism drives the annular bracket 34 to rotate, and the rotation drive motor 37 in the rotation drive assembly 320 is started. The rotation drive motor 37 drives the second rotating driven gear 317 to rotate through the second rotating driving gear 314 and the rotating transmission gear 315. The second rotating driven gear 317 is connected to the second gear shaft 313. The second gear shaft 313 is always meshed with the first gear ring 38 during the lifting process of the lifting seat 33, so that the rotation of the second gear shaft 313 drives the first gear ring 38 to rotate, and the rotation of the first gear ring 38 drives the annular bracket 34 to rotate on the lifting seat 33. The annular bracket 34 is used to drive the second unlocking component 321 to rotate, thereby rotating the lock core of the lock pin, so that the lock core rotates to the unlocking position. In order to prevent the lock core from exerting too much resistance on the rocker arm 322 during the clamping process, which causes the rocker arm 322 to be unable to clamp stably, after the rocker arm 322 clamps the lock core,The locking assembly 324 on one side of the rocker arm drive assembly 323 is activated, and the linear motor 3210 in the locking assembly 324 is retracted when not in operation. At this time, the pawl 3211 is disengaged from the ratchet 3212, and the ratchet 3212 can move freely. After the ratchet 3212 moves to the clamping position, the output shaft in the linear motor 3210 extends, and the pawl 3211 rotates about the second rotating shaft 326 toward the ratchet 3212. The pawl 3211 meshes with the teeth on the side of the ratchet 3212, and the pawl 3211 limits the ratchet 3212. At this time, the ratchet 3212 cannot rotate, thereby improving the clamping stability of the rocker arm 322.

[0068] The above-mentioned second unlocking assembly 321 can not only realize the clamping operation, but in some container lock pins with special structures, its unlocking mechanism is arranged on the side of the lower lock core of the lock pin. When the above-mentioned type of lock pin is unlocked, the two rocker arms 322 in the second unlocking assembly 321 can move independently, and the rocker arm 322 of the unlocking mechanism on the lock core can be driven by the driving assembly 323 to hook the unlocking mechanism on the side of the lock core using the working part 3213 on the rocker arm 322, and then the rocker arm 322 is driven to rotate by a slight rotation of the annular bracket 34, and the working part 3213 at the end of the rocker arm 322 drives the unlocking mechanism to move to the unlocking position, and then the working part 3213 clamps the unlocking mechanism, and the rocker arm 322 clamps the lock core by the drive of the driving mechanism, and then the lock core is rotated and unlocked by the rotation of the annular bracket 34;

[0069] In addition, the stepped structures on the upper and lower sides of the working part 3213 and the right-angled groove 3214 can be adapted to different unlocking mechanisms. Depending on the structure of the unlocking mechanism, the working part 3213 or the stepped structures on the upper and lower sides of the working part 3213 and the right-angled groove 3214 are used to contact the unlocking mechanism, and then the rocker arm 322 or the annular bracket 34 is rotated to toggle the unlocking mechanism to unlock. While unlocking, the two sets of rocker arms 322 can still clamp the lock core, and then the rotation of the annular bracket 34 drives the lock core to rotate to unlock.

[0070] When the lock pin is provided with a locking mechanism that needs to be pressed or rotated to unlock, the first unlocking mechanism 2 is first started after the container lock pin automatic disassembly and assembly fixture clamps the lock pin. First, the lifting assembly 23 in the first unlocking mechanism 2 is started, and the lifting motor 235 in the lifting assembly 23 drives the rotating wheel 234 to rotate clockwise. Since the rotating wheel 234 is eccentrically connected to the second connecting rod 233, the second connecting rod 233 moves upward when the rotating wheel 234 rotates, so that the second connecting rod 233 pushes the rotating telescopic assembly 24 upward. The rotating telescopic assembly 24 moves upward, causing the triangular connecting member 230 to rotate clockwise around the first rotating shaft 232 connected to the mounting seat 22, and the four triangular connecting members 230 on both sides of the mounting seat 22 rotate synchronously, so that the rotating telescopic assembly 24 moves upward in parallel. The lifting height of the rotating telescopic assembly 24 is controlled according to the rotation angle of the lifting 235, so that the rotating telescopic assembly 24 is lifted to the unlocking part in the middle of the lock pin. When the locking cam 210 is in the same position as the locking cam 210, the locking cam 210 moves in a direction that is substantially the same as the locking cam 210. When the locking cam 210 is in the same position as the locking cam 210, the locking cam 210 moves in a direction that is substantially the same as the locking cam 210. When the locking cam 210 is in the same position as the locking cam 210, the locking cam 210 moves in a direction that is substantially the same as the locking cam 210. When the locking cam 210 is in the same position as the locking cam 210, the locking cam 210 moves in a direction that is substantially the same as the locking cam 210. When the locking cam 210 is in the same position as the locking cam 210, the locking cam 210 moves in a direction that is substantially the same as the locking cam 210.When it is necessary to rotate and unlock, the telescopic drive motor 242 in the rotating telescopic assembly 24 is started, and the telescopic drive motor 242 drives the second screw 247 to rotate through the telescopic drive gear 243 and the telescopic driven gear 248. The second screw 247 is threadedly connected to the first gear shaft 245, so that the rotation of the second screw 247 drives the first gear shaft 245 to move inside the shell. The first gear shaft 245 moves outward and drives the unlocking head 210 to extend outward through the connecting shaft 211. The unlocking head 210 contacts the unlocking component on the lock pin, and the end of the unlocking component enters the tapered hole 213 on the unlocking head 210. Due to the tapered hole 213 13 is flared, so after the unlocking member enters the tapered hole 213, it is stuck under the action of the side wall of the tapered hole 213. Then, the rotary motor 241 is started, and the rotary motor 241 drives the first gear shaft 245 to rotate via the first rotary drive gear 244 and the first rotary driven gear 246. The first gear shaft 245 drives the unlocking head 210 to rotate via the connecting shaft 211. The unlocking head 210 drives the unlocking member to rotate to the unlocked position. The first unlocking mechanism then stops moving, so that the locking mechanism in the lock pin remains unlocked, allowing the lock cylinder unlocking mechanism to rotate and unlock the lock cylinder, thereby removing the lock pin from the container.

[0071] In summary, the present invention provides a lock pin clamping mechanism for clamping the lock pin body, and a first unlocking mechanism and a second unlocking mechanism for unlocking. During the disassembly and assembly process, the lock pin clamping assembly clamps the lock pin body, and the first unlocking mechanism and the second unlocking mechanism unlock the lock pin according to the type of the lock pin.
