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 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.

[0004] Most container lock pins are unlocked by rotating the lower lock core to drive the upper lock core to rotate. However, in some container lock pins with special structures, a locking mechanism is generally provided to prevent the lock pin from automatically unlocking during transportation. For example, a rotating or pressing structure is provided on the side of the lock pin. When unlocking, it is necessary to rotate the corresponding handle or press the locking mechanism inward before rotating the lower lock core to remove the lock pin. In order to ensure that the automatic disassembly and assembly fixture of the container lock pin can be applied to the unlocking of most lock pins, it is necessary to provide an unlocking mechanism that can unlock the above-mentioned type of lock pin. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the object of the present invention is to provide an unlocking mechanism for an automatic disassembly and assembly fixture of a container lock pin, which is used to solve the problem that some existing container lock pins in the prior art have a locking mechanism set on the side, and when the lock pin is disassembled and assembled, it is necessary to first unlock the locking mechanism and then unlock the lock pin, and the existing automatic disassembly and assembly fixture of the container lock pin lacks a structure that can unlock the above-mentioned locking structure.

[0006] In order to achieve the above-mentioned purpose and other related purposes, the present invention provides an automatic disassembly and assembly fixture unlocking mechanism for a container lock pin, including a mounting base for connecting an auxiliary unlocking structure with other equipment, an unlocking assembly is arranged on the mounting base, and the unlocking assembly includes an unlocking head, and a tapered hole is arranged in the middle of the unlocking head for clamping the unlocking part on the lock pin, the tapered hole is flared, and a card groove is symmetrically opened on the edge of the tapered hole, and a rotating telescopic assembly for driving the unlocking assembly to extend and rotate is arranged on the mounting base, the unlocking head is connected to the rotating telescopic assembly through a connecting shaft, and the rotating telescopic assembly is connected to the mounting base through a lifting assembly that drives it to rise and fall.

[0007] In one embodiment of the present invention, the rotary telescopic assembly includes a shell, a rotary driven gear is rotatably arranged in the middle of the shell, a gear shaft is rotatably arranged in the inside of the shell, the gear shaft is movably sleeved in the middle of the rotary driven gear and rotates with the rotary driven gear, the unlocking head is connected to one end of the gear shaft through a connecting shaft, the other end of the gear shaft is threadedly connected to a screw, and a telescopic drive motor is provided at the end of the shell to drive the screw to rotate.

[0008] In one embodiment of the present invention, a rotary drive motor for driving the rotary driven gear to rotate is provided on the outside of the shell, a rotary drive gear meshing with the rotary driven gear is provided on the output shaft of the rotary drive motor, a plurality of limit teeth arranged along the length are evenly spaced on the outer surface of the gear shaft, and the rotary driven gear is movably sleeved on the outside of the gear shaft and drives the gear shaft to rotate through the limit teeth.

[0010] In one embodiment of the present invention, the unlocking head is threadedly connected to the connecting shaft.

[0011] By adopting this technical solution: the unlocking head is threadedly connected to the connecting shaft, which facilitates the disassembly, assembly and replacement of the unlocking head.

[0012] In one embodiment of the present invention, the lifting assembly includes triangular connectors symmetrically arranged on both sides of the mounting base, with two triangular connectors symmetrically arranged on each side. The two adjacent corners of the triangular connectors are respectively rotatably connected to the mounting base and the bottom surface of the rotary telescopic assembly through a rotating shaft, and the other corners of the two triangular connectors on the same side are connected by a first connecting rod.

The rotating wheel is eccentrically connected to one end of the second connecting rod, and the other end of the second connecting rod is rotatably connected to the bottom surface of the rotary telescopic assembly.

[0013] By adopting this technical solution: the lifting motor in the lifting assembly drives the rotating wheel to rotate clockwise. Since the rotating wheel is eccentrically connected to the second connecting rod, the second connecting rod moves upward when the rotating wheel rotates, so that the second connecting rod pushes the rotating telescopic assembly upward. The rotating telescopic assembly moves upward, causing the triangular connecting piece to rotate clockwise around the rotating shaft connected to the mounting base, and the four triangular connecting pieces on both sides of the mounting base rotate synchronously, so that the rotating telescopic assembly moves upward in parallel. The lifting height of the rotating telescopic assembly is controlled according to the lifting rotation angle, so that the rotating telescopic assembly is lifted to a position flush with the unlocking component in the middle of the locking pin.

[0028] See also Figures 2 to 4 The lifting assembly 3 includes triangular connectors 30 symmetrically arranged on both sides of the mounting base 2, and two triangular connectors 30 are symmetrically arranged on each side. The two adjacent corners of the triangular connectors 30 are respectively rotatably connected to the mounting base 2 and the bottom surface of the rotating and telescopic assembly 4 through a rotating shaft 32. The other corners of the two triangular connectors 30 on the same side are connected through a first connecting rod 31.

Specifically, two rotating wheels 34 are symmetrically arranged. The second wheel connecting rod 33 is arranged between the two rotating wheels 34 and is rotatably connected to the two rotating wheels 34 through a rotating shaft. The rotating wheel 34 is arranged to be semicircular.

[0029] The working principle of an unlocking mechanism of an automatic disassembly and assembly fixture for a container lock pin is as follows: the automatic disassembly and assembly fixture for the container lock pin first scans and identifies the type of lock pin before disassembling and assembling the lock pin, and determines the unlocking method of the lock pin. When the lock pin is provided with a locking mechanism that needs to be pressed or rotated to unlock, the unlocking mechanism is activated after the automatic disassembly and assembly fixture for the container lock pin clamps the lock pin. First, the lifting component 3 in the auxiliary structure mechanism is started, and the lifting motor 35 in the lifting component 3 drives the rotating wheel 34 to rotate clockwise. Since the rotating wheel 34 is eccentrically connected to the second connecting rod 33, the second connecting rod 33 moves upward when the rotating wheel 34 rotates, so that the second connecting rod 33 pushes the rotating telescopic component 4 upward, and the rotating telescopic component 4 moves upward, so that the triangular connecting member 30 is connected to the mounting seat 2 around. The rotating shaft 32 rotates clockwise, and the four triangular connecting members 30 on both sides of the mounting seat 2 rotate synchronously, so that the rotary telescopic assembly 4 moves upward in parallel. The lifting height of the rotary telescopic assembly 4 is controlled according to the rotation angle of the lifting 35, so that the rotary telescopic assembly 4 is lifted to a position flush with the unlocking component in the middle of the lock pin. When it is necessary to press to unlock, the telescopic drive motor 42 in the rotary telescopic assembly 4 is started, and the telescopic drive motor 42 drives the screw 47 to rotate through the telescopic drive gear 43 and the telescopic driven gear 48. The screw 47 is threadedly connected to the gear shaft 45, so that the gear shaft 45 is driven to move inside the shell by the rotation of the screw 47. The gear shaft 45 moves outward and drives the unlocking head 10 to extend outward through the connecting shaft 11, and the unlocking head 10 is aligned with the lock pin. After the unlocking part contacts, the telescopic drive motor 42 continues to drive the screw 47 to rotate, and the unlocking head 10 continues to move to press the unlocking part. After the unlocking part is pressed, the telescopic drive motor 42 stops moving, and the unlocking head 10 remains in the pressed unlocking state. Then the lock cylinder unlocking mechanism in the automatic disassembly and assembly fixture of the container lock pin unlocks the lock cylinder so that the lock pin can be removed from the container; when rotation unlocking is required, the telescopic drive motor 42 in the rotary telescopic assembly 4 is started, and the telescopic drive motor 42 drives the screw 47 to rotate through the telescopic drive gear 43 and the telescopic driven gear 48. The screw 47 is threadedly connected to the gear shaft 45, so that the gear shaft 45 is driven to move inside the shell by the rotation of the screw 47, and the gear shaft 45 moves outward through the connecting shaft 11 The dynamic unlocking head 10 extends outward, and the unlocking head 10 contacts the unlocking component on the lock pin. The end of the unlocking component enters the tapered hole 13 on the unlocking head 10. Since the tapered hole 13 is flared, the unlocking component will be stuck under the action of the side wall of the tapered hole 13 after entering the tapered hole 13. Then the rotary drive motor 41 is started, and the rotary drive motor 41 drives the gear shaft 45 to rotate through the rotary drive gear 44 and the rotary driven gear 46. The gear shaft 45 drives the unlocking head 10 to rotate through the connecting shaft 11. The unlocking head 10 drives the unlocking component to rotate to the unlocking position, and then the unlocking mechanism stops moving so that the locking mechanism in the lock pin remains unlocked, so that the lock cylinder unlocking mechanism can rotate and unlock the lock cylinder to remove the lock pin from the container.

[0030] In summary, the present invention provides an unlocking head connected to a rotating and telescopic assembly and a lifting assembly. The lifting assembly adjusts the vertical position of the unlocking head so that it aligns with the lock pin unlocking component. The rotating and telescopic assembly drives the unlocking head to extend and rotate, thereby enabling the unlocking head to be pressed or rotated to unlock. This effectively enables unlocking of lock pins requiring these unlocking methods, expands the applicability of the automatic container lock pin disassembly and assembly fixture, and provides a simple structure and ease of use. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
