Description

Technical Field

[0001] The invention relates to an unlocking mechanism for an automatic disassembly and assembly fixture of 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 transportation. 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, gaps often appear between the upper and lower containers due to wind or minor collisions. For transportation safety, the upper and lower containers must be connected with special locking pins to ensure that there is no gap between the upper and lower containers 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.

[0004] The container lock pin is generally provided with two upper and lower lock cores, which are linked to each other. When removing the lock pin, the lower lock core can be rotated to drive the upper lock core to rotate to the unlocked position and then the lock pin can be removed. Similarly, during installation, the upper lock core can be rotated to the unlocked position by rotating the lower lock core, and then the upper lock core of the lock pin is inserted into the lock hole of the container. The lower lock core is released, and the elastic mechanism inside the lock core will automatically restore the lock core to the locked position, thereby realizing the installation of the lock pin. Therefore, in order to facilitate the disassembly and assembly of the lock pin, it is necessary to design an unlocking mechanism that can realize the clamping and rotation of the lock core of the lock pin and can be applied to most lock core structures.

A plurality of screw holes are evenly spaced along the circumference of the upper end surface of the annular bracket 4. The unlocking components 21 are detachably connected to the annular bracket 4 by screws.

[0043] For details, please refer to Figure 8The unlocking assembly 21 includes a bracket 25 fixedly connected to the annular bracket 4. A plurality of screw holes are evenly spaced along the circumferential direction on the upper surface of the annular bracket 4. Corresponding through holes are provided on the bracket 25. The bracket 25 is fixedly connected to the annular bracket 4 by screws passing through the through holes. The two sets of unlocking assemblies 21 inside the annular bracket 4 are rotationally symmetrically arranged.

The two rocker arms 22 rotate in the same direction during the clamping operation, and clamping is performed by the working portion 213 at the end of the rocker arm 22.

[0044] See also Figures 9 to 11 A rocker arm 22 is rotatably provided on the upper inner side of the bracket 25, and a rotating shaft 26 is connected to the lower end of the rocker arm 22. The rotating shaft 26 is rotatably connected to the bracket 25. The rotating shaft 26 is arranged perpendicular to the upper surface of the bracket 25.

The fan-shaped ratchet 212 rotates above A connecting rod 29 is connected, and a connecting portion 28 extends outward from one side of the rotating shaft 26.

A linear motor 210 is provided on one side of the pawl 212. The output shaft of the linear motor 210 is connected to the middle of one side of the pawl 211 and drives the pawl 211 to rotate around the connection with the mounting bracket 25 through the linear motion of the output shaft.

[0045] See also Figure 12 The rocker arm 22 is arc-shaped and extends upward at an angle. The end of the rocker arm 22 is bent toward the inside of the arc to form a working portion 213. The upper surface of the working portion 213 is stepped, and a right-angle groove 214 is provided at the bottom of the working portion 213.

[0046] The working principle of the unlocking mechanism of the automatic disassembly and assembly fixture of a container lock pin is as follows:

[0047] When the automatic disassembly and assembly fixture of the container lock pin disassembles and assembles the lock pin on the container, the automatic disassembly and assembly fixture of the container lock pin moves to the bottom of the lock pin under the action of the mechanical arm, aligns the center of the circle of the annular bracket 4 in the unlocking mechanism 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 4 in the unlocking mechanism. After the unlocking mechanism moves into place, the scanning device scans the structure of the lock pin, determines the type of the lock pin and calculates the unlocking method of the lock pin, and then the lifting drive assembly 6 in the unlocking mechanism is started, the lifting drive motor 5 is started, and the lifting drive motor 5 drives the second ring gear 9 to rotate through the cooperation of the lifting drive gear 18 and the lifting transmission gear 19. The second ring gear 9 is meshed with the lifting driven gear 12, thereby The three screw rods 11 are driven to rotate synchronously by the lifting driven gear 12 at the same time. Since the lifting seat 3 is threadedly connected to the screw rod 11 through the connecting part 10, the lifting seat 3 is driven to lift. The movement of the lifting seat 3 drives the unlocking component 21 to move upward, so that the upper end of the rocker arm 22 in the unlocking component 21 is flush with the surface of the lock cylinder below the lock pin. Then the driving component 23 in the unlocking mechanism is started, and the motor 27 in the driving component 23 drives the fan-shaped ratchet 212 to rotate toward the inner side of the annular bracket 4. The fan-shaped ratchet 212 is connected to the connecting part 28 on the rotating shaft 26 through the connecting rod 29. A cam mechanism is formed between the fan-shaped ratchet 212, the connecting rod 29 and the connecting part 28. The rotating shaft 26 is driven to rotate counterclockwise by the rotation of the fan-shaped ratchet 212, and the two sets of unlocking are completed. The rotating shaft 26 in the assembly rotates synchronously, and the rocker arm 22 connected to the rotating shaft 26 moves toward the center of the annular bracket 4 under the drive of the rotating shaft 26. The working parts 213 of the two rocker arms 22 contact the surface of the lock core below the lock pin to clamp the lock core, and then the rotation drive assembly 20 in the unlocking mechanism drives the annular bracket 4 to rotate, and the rotation drive motor 7 in the rotation drive assembly 20 is started. The rotation drive motor 7 drives the rotation driven gear 17 to rotate through the rotation drive gear 14 and the rotation transmission gear 15. The rotation driven gear 17 is connected to the gear shaft 13. The gear shaft 13 is always engaged with the first gear ring 8 during the lifting process of the lifting seat 3, so that the first gear ring 8 is driven to rotate by the rotation of the gear shaft 13, and the annular bracket 4 is driven to be lifted and lowered by the rotation of the first gear ring 8. The seat 3 rotates, and the annular bracket 4 is used to drive the unlocking assembly 21 to rotate, thereby rotating the lock cylinder of the lock pin, so that the lock cylinder rotates to the unlocking position. During the clamping process, in order to prevent the lock cylinder from exerting too much resistance on the rocker arm 22, resulting in the rocker arm 22 being unable to clamp stably, after the rocker arm 22 clamps the lock cylinder, the locking assembly 24 on one side of the driving assembly 23 is started, and the linear motor 210 in the locking assembly 24 contracts when not working. At this time, the pawl 211 disengages from the ratchet 212, and the ratchet 212 can move freely. After the ratchet 212 moves to the clamping position, the output shaft in the linear motor 210 extends, and the pawl 211 rotates around the rotating axis to one side of the ratchet 212. The pawl 211 meshes with the teeth on the side of the ratchet 212, and the pawl 211 limits the ratchet 212.At this time, the ratchet 212 cannot rotate, thereby improving the clamping stability of the rocker arm 22;

[0048] The unlocking assembly 21 can not only realize the clamping and unlocking operation, but in some container lock pins with special structures, the unlocking mechanism is arranged on the side of the lower lock core of the lock pin. When the lock pin of the above type is unlocked, the two rocker arms 22 in the unlocking assembly 21 can move independently, and the rocker arm 22 of the unlocking mechanism on the lock core can be driven by the driving assembly 23 to hook the unlocking mechanism on the side of the lock core using the working part 213 on the rocker arm 22, and then the rocker arm 22 is driven to rotate by a slight rotation of the annular bracket 4. The working part 213 at the end of the rocker arm 22 drives the unlocking mechanism to move to the unlocking position, and then the working part 213 clamps the unlocking mechanism, and the rocker arm 22 clamps the lock core by the drive of the driving assembly, and then the lock core is rotated and unlocked by the rotation of the annular bracket 4;

[0049] In addition, the stepped structure on the upper and lower sides of the working part 213 and the right-angle groove 214 can be suitable for different unlocking mechanisms. According to the structure of different unlocking mechanisms, the working part 213 or the stepped structure on the upper and lower sides of the working part 213 and the right-angle groove 214 are used to contact the unlocking mechanism, and then the unlocking mechanism is unlocked by rotating the rocker arm 22 or the annular bracket 4. At the same time, the two sets of rocker arms 22 can still clamp the lock core, and then the lock core is driven to rotate by the rotation of the annular bracket 4 to achieve unlocking.

[0050] In summary, the unlocking mechanism of the present invention is composed of a base, an annular bracket disposed on the base, and an unlocking assembly on the annular bracket. The base is provided with a lifting drive assembly and a rotation drive assembly for driving the annular bracket to lift and rotate, thereby realizing the free lifting and rotating movement of the annular bracket. The two sets of unlocking assemblies on the annular bracket cooperate with each other, and the two sets of unlocking assemblies operate independently. The lock cylinder is clamped by the rotation of the rocker arm in the unlocking assembly, and then the lock cylinder is driven to rotate by the annular bracket to unlock, effectively realizing the automatic unlocking of the lock pin. In addition, the unlocking assembly adopts a rocker arm of a specific structure. In addition to realizing the clamping function, the rocker arm can also cooperate with the annular bracket and the drive assembly to unlock the unlocking mechanism on the side of the lock cylinder, making the clamping structure applicable to most lock pin unlocking operations, expanding the scope of application of the container lock pin automatic disassembly and assembly fixture, and improving the disassembly and assembly efficiency of the container lock pin automatic disassembly and assembly fixture. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial utilization value.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
