Description

Technical Field

[0001] The invention relates to a lock pin clamping mechanism of a container lock pin automatic disassembly and assembly fixture, belonging to the technical field of container-specific equipment. 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 during 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] During the process of disassembling and assembling the lock pin of the container, it is necessary to clamp the lock pin first to facilitate the installation or removal of the lock pin after unlocking. When clamping the lock pin, it is also necessary to ensure that the clamping position of the lock pin is always located in the center of the unlocking mechanism. This requires the clamping arm in the clamping mechanism of the lock pin to move synchronously. Moreover, due to the different structures and shapes of different lock pins, the clamping mechanism needs to be able to clamp lock pins of different structures and shapes. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a lock pin clamping mechanism for an automatic disassembly and assembly fixture for container lock pins, which is used to solve the problems in the prior art that the existing clamping mechanisms are not suitable for clamping lock pins of different shapes and structures, and cannot ensure the accuracy of the lock pin position during the clamping process.

[0006] To achieve the above-mentioned objectives and other related objectives, the present invention provides a container lock pin automatic disassembly and assembly fixture lock pin clamping mechanism, including a base, on which two groups of clamping components are symmetrically arranged, and the two groups of clamping components are connected to the base via a longitudinal moving component, and the longitudinal moving component drives the two groups of clamping components to move synchronously longitudinally toward or relative to each other, and the clamping component includes a laterally arranged mounting seat, and the mounting seat is provided with a first clamping arm and a second clamping arm that move synchronously toward or away from each other laterally to realize the clamping function.

[0007] In one embodiment of the present invention, the longitudinal moving component includes two bidirectional screw rods arranged longitudinally and in parallel, and a longitudinal slide is movably provided on the two bidirectional screw rods. The two ends of the longitudinal slide are respectively threadedly connected to the two bidirectional screw rods, the mounting seat is connected to the longitudinal slide, and a driving component is provided in the middle of the base to drive the two bidirectional screw rods to rotate synchronously in opposite directions.

[0008] In one embodiment of the present invention, connecting parts are bent upward on both sides of the base, and both ends of the two bidirectional screw rods are rotatably connected to the connecting parts.

[0009] In one embodiment of the present invention, the two bidirectional screw rods have opposite thread directions, and the driving assembly drives the two bidirectional screw rods to rotate in opposite directions.

[0010] By adopting this technical solution: the driving assembly drives the two bidirectional screws to rotate synchronously in opposite directions. Since the threads on the two bidirectional screws are in opposite directions, the longitudinal slides on the bidirectional screws move in the same direction under the action of the two bidirectional screws when the two bidirectional screws move in opposite directions. The rotation of the bidirectional screws causes the two longitudinal slides to drive the clamping assemblies to move toward or relative to each other.

[0011] In one embodiment of the present invention, the driving assembly includes a fixed seat fixedly arranged in the middle of the base, the two bidirectional screw rods pass through the fixed seat, and a driven gear is fixedly sleeved in the middle of the two bidirectional screw rods. A driving motor is fixedly arranged on one side of the fixed seat, and a driving gear is arranged on the output shaft of the driving motor. The driving gear is meshed with the driven gear on one of the bidirectional screw rods, and the driven gear on the other bidirectional screw rod is meshed with the driving gear through a transmission gear.

[0012] By adopting this technical solution: the driving motor is started, the driving motor drives the driving gear to rotate, and the driving gear meshes with the driven gear on one of the two-way screw rods, and the two-way screw rod is driven to rotate in the opposite direction of the driving gear through the action of the gear. The driven gear on the other two-way screw rod is connected to the driving gear through the transmission gear. When the driving gear rotates, the driven gear on the two-way screw rod has the same rotation direction as the driving gear through the action of the transmission gear. Therefore, the above structure makes the two two-way screw rods rotate in opposite directions, and since the directions of the threads on the two two-way screw rods are also set in opposite directions, the two two-way screw rods will drive the longitudinal slide to move in the same direction. At the same time, since the rotation directions of the two two-way screw rods are opposite, the forces exerted on the longitudinal slide by the two two-way screw rods during rotation cancel each other out, thereby preventing the longitudinal slide from being offset or stuck due to the force during the rotation of the two-way screw rods.

[0013] In one embodiment of the present invention, a connecting block is provided on the mounting seat, a connecting rod is provided on one side of the connecting block for transverse sliding, a bidirectional motor is provided at one end of the connecting rod, and the other end is connected to the first clamping arm, the second clamping arm is slidingly provided on the other side of the connecting block opposite to the connecting rod, a screw is connected to the output shaft of the bidirectional motor, the second clamping arm is threadedly connected to the screw, a first transmission tooth and a second transmission tooth are respectively provided on the opposite sides of the connecting rod and the second clamping arm, and a gear meshing with the first transmission tooth and the second transmission tooth is provided on the connecting block.

[0014] By adopting this technical solution: the bidirectional motor in the clamping assembly is started, and the output shaft of the bidirectional motor drives the screw to rotate. Since the second clamping arm is threadedly connected to the screw, the second clamping arm moves toward the first clamping arm under the drive of the screw. When the second clamping arm moves, the second transmission tooth on the side of the second clamping arm drives the first transmission tooth to move through the gear, so that when the second clamping arm moves toward the first clamping arm, the first clamping arm moves synchronously toward the second clamping arm under the action of the connecting rod, and the first clamping arm and the second clamping arm move synchronously toward each other to clamp the middle part of the locking pin.

[0015] In one embodiment of the present invention, the mounting seat is connected to the longitudinal slide via an adjustment mechanism, and the adjustment mechanism can perform a small-range lateral adjustment on the position of the mounting seat.

[0016] In one embodiment of the present invention, the adjustment mechanism includes connecting plates arranged at both ends of the bottom surface of the mounting seat and connecting blocks arranged at both ends of the bottom surface of the longitudinal slide seat. Two guide rods are arranged in parallel between the two connecting plates. The two guide rods pass through the connecting blocks and move freely laterally inside the connecting blocks. A fixed block is fixed in the middle of the guide rods, and a spring is provided on the guide rod between the fixed block and the two connecting blocks.

[0017] By adopting this technical solution: in the process of the lock pin clamping mechanism clamping the lock pin, due to the different lock pin structures, some lock pins have different thicknesses on both sides, or some lock pins have a certain inclination angle. When the clamping assembly clamps the above lock pin, a certain misalignment needs to be generated between the two clamping assemblies in order to clamp the lock pin. Therefore, in the process of clamping the above lock pin, the clamping assembly is subjected to the reaction of the lock pin. The clamping assembly produces a small lateral position under the action of the reaction force of the lock pin. The guide rod on the bottom surface of the mounting seat in the clamping assembly moves with the clamping assembly. A spring is provided between the fixed block in the middle of the guide rod and the connecting block on the longitudinal slide. The spring compression enables the guide rod to perform a small lateral displacement, so that the clamping assembly can perform a small position to adapt to the clamping of the lock pin. After clamping is completed, the guide rod is reset by the action of the spring, thereby resetting the two groups of clamping assemblies. The above structure effectively realizes small lateral adjustment of the clamping assembly during the clamping process, thereby expanding the application range of the clamping assembly and improving the stability of clamping.

[0018] In one embodiment of the present invention, connecting seats for fixing the spring are provided on both sides of the fixing block.

[0019] In one embodiment of the present invention, the connecting rod is movably connected to the bidirectional motor and a spring is provided at the connection.

[0020] By adopting this technical solution: after the bidirectional motor drives the first clamping arm and the second clamping arm to clamp the locking pin, when the bidirectional motor is powered off, the first clamping arm and the second clamping arm will remain in place. At this time, if the locking pin moves slightly, the first clamping arm and the second clamping arm will lose their clamping force on the locking pin and cannot clamp it. Therefore, a spring is provided. After the bidirectional motor is powered off, the spring applies an elastic force to the second clamping arm, so that the first clamping arm and the second clamping arm always stably clamp the locking pin.

[0021] As described above, the container lock pin automatic disassembly and assembly fixture lock pin clamping mechanism of the present invention has the following beneficial effects:

[0022] The two groups of clamping assemblies in the present invention realize longitudinal movement through the longitudinal moving assembly. The first clamping arm and the second clamping arm in the clamping assembly can move synchronously for clamping, effectively realizing stable clamping of the locking pin, and the first clamping arm and the second clamping arm keep the position of the locking pin unchanged during the synchronous movement and clamping process, thereby improving the accuracy of clamping. The two clamping assemblies operate independently, and can realize the clamping of the asymmetric structure of the locking pin. An adjustment assembly is also provided between the clamping assembly and the longitudinal moving assembly. The adjustment assembly can perform slight longitudinal adjustments on the clamping assembly, so that the clamping assembly can be suitable for clamping the locking pins with asymmetric structures on both sides during the clamping process, thereby expanding the scope of application of the locking pin clamping mechanism, and the device structure is simple and easy to use.

[0037] The working principle of the lock pin clamping mechanism of a container lock pin automatic disassembly and assembly fixture is:

[0038] The automatic disassembly and assembly fixture of the container lock pin is installed on the mechanical arm. When the container lock pin is disassembled, the automatic disassembly and assembly fixture of the container lock pin is first moved to the bottom of the lock pin through the mechanical arm. The mechanical arm aligns the center of the lock pin clamping mechanism 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 is flush with the middle position of the lock pin. The longitudinal moving component 2 in the lock pin clamping mechanism runs, and the drive motor 8 is started. The drive motor 8 drives the two bidirectional screw rods 6 to rotate synchronously in opposite directions through the drive gear 20, the transmission gear 21 and the driven gear 19. Due to the square thread on the two bidirectional screw rods 6, the two bidirectional screw rods 6 rotate synchronously in opposite directions. The two bidirectional screw rods 6 are in opposite directions, so when the two bidirectional screw rods 6 move in opposite directions, the longitudinal slide 4 on the bidirectional screw rods 6 moves in the same direction under the action of the two bidirectional screw rods 6. The rotation of the bidirectional screw rods 6 makes the two longitudinal slides 4 drive the clamping assembly 3 to move in opposite directions until they move to both sides of the lock pin. Then the clamping assembly 3 is operated, and the bidirectional motor 9 in the clamping assembly 3 is started. The output shaft of the bidirectional motor 9 drives the screw rod 11 to rotate. Since the second clamping arm 16 is threadedly connected to the screw rod 11, the second clamping arm 16 moves toward the first clamping arm 17 under the drive of the screw rod 11. When the second clamping arm 16 moves, the second clamping arm 17 moves. The second transmission tooth 15 on the side of the second clamping arm 16 drives the first transmission tooth 12 to move through the gear 14, so that when the second clamping arm 16 moves toward the first clamping arm 17, the first clamping arm 17 moves synchronously toward the second clamping arm 16 under the action of the connecting rod 10, and the first clamping arm 17 and the second clamping arm 16 move synchronously toward each other to clamp the middle part of the lock pin. After the bidirectional motor 9 drives the first clamping arm 17 and the second clamping arm 16 to clamp the lock pin, when the bidirectional motor 9 is powered off, the first clamping arm 17 and the second clamping arm 16 will remain in place. At this time, if the lock pin moves slightly, the first clamping arm 17 and the second clamping arm 16 will remain in place. The arm 17 and the second clamping arm 16 will lose their clamping force on the lock pin and cannot achieve clamping. Therefore, a spring 30 is provided. After the bidirectional motor 9 is powered off, the spring 30 applies an elastic force to the second clamping arm 16, so that the first clamping arm 17 and the second clamping arm 16 always stably clamp the lock pin. After the lock pin is unlocked by the unlocking mechanism in the automatic disassembly and assembly fixture of the container lock pin, the mechanical arm moves downward to disengage the lock pin from the lock hole, and then the mechanical arm transports the lock pin to the placement position. The longitudinal moving component 2 and the clamping component 3 in the lock pin clamping mechanism are reset to release the lock pin and place it, thereby realizing automatic disassembly and assembly of the lock pin.

[0039] In the process of the lock pin clamping mechanism clamping the lock pin, due to the different lock pin structures, some lock pins have asymmetrical structures on both sides. When the clamping assembly 3 clamps the above lock pin, a certain misalignment is required between the two clamping assemblies 3 to clamp the lock pin. Therefore, in the process of clamping the above lock pin, the clamping assembly 3 is subjected to the reaction of the lock pin. The clamping assembly 3 produces a small lateral position under the action of the reaction force of the lock pin. The guide rod 27 on the bottom surface of the mounting seat 7 in the clamping assembly 3 moves with the clamping assembly 3. The guide rod A spring 26 is provided between the fixed block 23 in the middle of 27 and the connecting block 29 on the longitudinal slide 4. The compression of the spring 26 enables the guide rod 27 to perform a small lateral displacement, so that the clamping assembly 3 can be slightly positioned to adapt to the clamping of the locking pin. After the clamping is completed, the guide rod 27 is reset by the force of the spring 26, thereby resetting the two groups of clamping assemblies 3. The above structure effectively realizes the small lateral adjustment of the clamping assembly 3 during the clamping process, thereby expanding the application range of the clamping assembly 3 and improving the stability of the clamping.

[0040] In summary, the two groups of clamping assemblies in the present invention realize longitudinal movement through the longitudinal moving assembly, and the first clamping arm and the second clamping arm in the clamping assembly can move synchronously for clamping, effectively realizing stable clamping of the lock pin, and the first clamping arm and the second clamping arm keep the position of the lock pin unchanged during the synchronous movement and clamping process, thereby improving the accuracy of clamping, and the two clamping assemblies operate independently, which can realize the clamping of the asymmetric lock pin, and an adjustment assembly is further provided between the clamping assembly and the longitudinal moving assembly, and the adjustment assembly can make a small longitudinal adjustment to the clamping assembly, so that the clamping assembly can be suitable for clamping the asymmetric lock pin during the clamping process, thereby expanding the scope of application of the lock pin clamping mechanism, and the device structure is simple and easy to use. Therefore, the present invention effectively overcomes the various shortcomings of the prior art and has a 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.
