Description

Technical Field

[0001] The present invention relates to the technical field of container handling, and more specifically, to a container handling device. Background Art

[0002] A container handling device refers to a mechanical device used to efficiently transfer containers between transportation tools such as ships, trains, and trucks. By the mutual cooperation of a handling platform and a container, the loading and unloading efficiency of goods can be improved, and labor costs and time consumption are reduced.

[0003] When the existing container handling devices are in use, there are two handling methods. One is to lift the container onto the handling platform by means of hoisting, and it is necessary to use a cable for hoisting operation, which is relatively cumbersome and complex, and has a low usage frequency. The other is translational handling, that is, to translate it onto the handling platform through a first slide rail and a pulley at the bottom of the container. Among them, translational handling is widely used.

[0004] In actual use of the prior art, since translational handling depends on the first slide rail and the pulley, it is necessary to accurately align the first slide rail and the pulley at the bottom of the container, and the operation is relatively complex. At the same time, the first slide rail and the pulley are prone to wear during long-term use, resulting in an increase in the gap between the first slide rail and the pulley, thereby increasing the risk of the container shifting or falling off during movement, affecting the safety and stability of the handling process.

[0005] Therefore, in view of the above technical problems, it is necessary to provide a container handling device. Summary of the Invention

[0006] The purpose of the present invention is to provide a container handling device to solve the above problems.

[0007] In order to achieve the above purpose, the technical solution provided by an embodiment of the present invention is as follows: A container handling device includes a handling platform, an anti-dropping component, and a limiting component. A pair of connecting frames are symmetrically connected to the upper surface of the handling platform, and a lifting plate is installed on the upper surface of the handling platform; the anti-dropping component is arranged inside the lifting plate. The anti-dropping component includes a pair of protective plates symmetrically installed on the upper surface of the lifting plate. A chute is opened inside the two protective plates. A moving block is slidably connected inside the chute. A flipping member is arranged on the side of the moving block. An electromagnetic plate is fixedly connected to the side of the protective plate close to the chute; the limiting component is arranged inside the lifting plate. A plurality of rotating grooves are opened inside the limiting component. A rotating rod is rotatably connected inside the rotating groove through a bearing. Limiting blocks are respectively installed at both ends of the rotating rod. An arc-shaped tube is installed inside the rotating groove. The arc-shaped tube is filled with an electrorheological fluid.

[0008] As a further improvement of the present invention, a rigid pad is installed on the outer surface at the exact center of the arc-shaped tube, and elastic pads are respectively installed on the outer surface of the arc-shaped tube away from the rigid pad. The rigid pad is made of a high-strength material, and the elastic pad is made of an elastic material. The rigid pad provides rigid support, ensuring the structural stability of the limit block in the fixed state and preventing excessive deformation. At the same time, the elastic pad can absorb energy when an impact occurs, reducing the impact force on other parts of the system and protecting the safety of the equipment and goods.

[0009] As a further improvement of the present invention, a buffer block is installed between the limit block and the rotating groove. The buffer block is made of a buffer elastic material. When the limit block is subjected to pressure, the buffer block can effectively absorb energy and reduce the impact force on other parts of the system.

[0010] As a further improvement of the present invention, a sliding block is slidably connected to the outer surface of the arc-shaped tube. The outer surface of the sliding block is connected to the bottom of the limit block. As the limit block moves, the sliding block slides along the surface of the arc-shaped tube, squeezing the electrorheological fluid so that it accumulates between the rigid pads, fixing the limit block in a position perpendicular to the lifting plate, thereby alleviating the forward impact force of the container and fixing the container that reaches the designated position.

[0011] As a further improvement of the present invention, the flipping member includes a second motor fixedly installed on the side of the moving block. The output shaft end of the second motor is fixedly connected to a rotating shaft through a coupling. A flipping plate is fixedly connected to the outer surface of the rotating shaft. By driving the rotating shaft to rotate by the second motor, the flipping plate is rotated to the required angle.

[0012] As a further improvement of the present invention, an electromagnet is installed on the upper surface of the electromagnetic plate. A first magnetic block is arranged inside the flipping plate. The first magnetic block is magnetically connected to the electromagnetic plate. A second magnetic block is installed inside the limit block. The second magnetic block is magnetically connected to the first magnetic block and the second magnetic block is magnetically connected to the electromagnetic plate, ensuring that the flipping plate can stably adsorb and push the container.

[0013] As a further improvement of the present invention, a plurality of containers are installed on the upper surface of the loading and unloading platform. An inclined plate is installed on the upper surface of the loading and unloading platform to help the containers be smoothly transferred from the ground or a transport vehicle to the loading and unloading platform.

[0014] As a further improvement of the present invention, a protective pad is installed on the outer surface of the limit block. The protective pad is made of a wear-resistant elastic material. The protective pad increases the wear resistance and buffering effect of the limit block, reduces the damage to the equipment and goods caused by direct impact, and further protects the equipment and goods.

[0015] As a further improvement of the present invention, a lifting assembly is installed on the upper surface of the loading and unloading platform. The lifting assembly includes a pair of connecting blocks symmetrically installed on the upper surface of the connecting frame. The lower surfaces of the two connecting blocks are fixedly connected with a first motor. The output shaft end of the first motor is fixedly connected with a lead screw through a coupling. A plurality of universal wheels are fixedly connected to the bottom of the loading and unloading platform. The first motor is connected to the lead screw through a coupling to drive the lead screw to rotate.

[0016] As a further improvement of the present invention, a sleeve is threadedly connected to the outer surface of the lead screw. The sleeves are fixedly installed with a lifting plate. A second slide rail is provided inside the connecting block. The sleeve is slidably connected to the inside of the second slide rail, so that the sleeve moves up and down along the thread on the surface of the lead screw. At the same time, when the sleeve moves, it slides in the second slide rail to ensure the stable movement of the lifting plate in the vertical direction.

[0017] Compared with the prior art, the advantages of the present invention are as follows: In this solution, by starting the first motor to drive the lead screw to rotate, the sleeve is driven to move along the second slide rail, so that the lifting plate rises or falls to an appropriate height, and then the container is placed on the inclined plate and the loading and unloading platform to perform the loading and unloading work on the container. By starting the second motor to drive the rotating shaft to rotate, the turning plate contacts the surface of the container, and the electromagnetic plate generates a magnetic force to adsorb the first magnetic block, and the container is pushed forward. The whole process does not require manual intervention, which greatly simplifies the operation process. At the same time, by repeatedly starting the turning member and the electromagnetic plate, multiple containers can be continuously pushed into the loading and unloading platform to achieve efficient loading and unloading. Due to the repulsion of the same-sex magnetic poles between the second magnetic block and the electromagnetic plate, the second magnetic block generates an opposite magnetic force, causing the limiting block and the rotating rod to rotate. Finally, the limiting block rotates to an inclined position to ensure the stability of the container during the movement, avoiding accidental sliding or collision. The wear resistance and buffering effect of the limiting block can be increased through the protective pad on the outer surface of the limiting block, further protecting the equipment and goods. At the same time, the limiting block can fix the container to prevent the container from sliding or colliding due to the steep road surface during the movement of the loading and unloading platform. The impact force of the container can be absorbed during the rotation of the buffer turntable, reducing the damage to the surface of the container, thereby protecting the equipment and goods. As the limiting block moves, when the sliding block slides along the surface of the arc-shaped tube, and the limiting block can be fixed due to the electrorheological fluid being energized, the forward impact force of the container is relieved, ensuring the stability of the container. Thus, the positions and states of each component can be automatically adjusted according to the size and weight of the container, which is applicable to containers of different specifications, and can effectively prevent the container from falling off during the loading and unloading process, ensuring the normal operation of the device. By applying an electric field, the electrorheological fluid becomes very viscous, forming a solid-like support structure to fix the limit block in the vertical position. The sliding block on the surface of the arc-shaped tube presses the electrorheological fluid, and through the mutual cooperation of the elastic pad and the rigid pad, it ensures that the limit block will not be overly deformed when subjected to pressure. Thus, by using the electro-control regulation of the electrorheological fluid, dynamic buffering and fixing functions can be achieved. At the same time, energy is absorbed when an impact occurs, reducing damage to equipment and goods, improving the safety of the system, and to a certain extent, fixing the container in place. Meanwhile, the positions and quantities of the rotating grooves and buffer turntables on the lifting plate can be flexibly set according to the size of the container to adapt to containers of different specifications, ensuring efficient and safe operation when handling containers of various sizes.

Detailed Embodiment

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. Embodiment

[0021] Please refer to Figures 1 - 6 , a container loading and unloading device, including a loading and unloading platform 1, a pair of connecting frames 101 symmetrically connected to the upper surface of the loading and unloading platform 1, and a lifting plate 204 installed on the upper surface of the loading and unloading platform 1.

[0022] Specifically, the anti-detachment component 3 is arranged inside the lifting plate 204. The anti-detachment component 3 includes a pair of protection plates 205 symmetrically installed on the upper surface of the lifting plate 204. A chute 301 is opened inside the two protection plates 205. A moving block 304 is slidably connected inside the chute 301. A flipping member 305 is arranged on the side of the moving block 304. An electromagnetic plate 303 is fixedly connected to the side of the protection plate 205 near the chute 301. The flipping member 305 includes a motor two 3051 fixedly installed on the side of the moving block 304. The output shaft end of the motor two 3051 is fixedly connected to a rotating shaft 3052 through a coupling. A flipping plate 3053 is fixedly connected to the outer surface of the rotating shaft 3052.

[0023] A plurality of containers 103 are installed on the upper surface of the loading and unloading platform 1. An inclined plate 5 is installed on the upper surface of the loading and unloading platform 1. A lifting component 2 is installed on the upper surface of the loading and unloading platform 1. The lifting component 2 includes a pair of connecting blocks symmetrically installed on the upper surface of the connecting frame 101. The lower surfaces of the two connecting blocks are fixedly connected to a motor one 201. The output shaft end of the motor one 201 is fixedly connected to a lead screw 202 through a coupling. A plurality of universal wheels 203 are fixedly connected to the bottom of the loading and unloading platform 1. The outer surface of the lead screw 202 is threadedly connected to a sleeve. The sleeves are fixedly installed with the lifting plate 204. A slide rail two is opened inside the connecting block. The sleeve is slidably connected to the inside of the slide rail two.

[0024] An electromagnet is installed on the upper surface of the electromagnetic plate 303. The electromagnetic plate 303 contains an electromagnet inside, which generates an adjustable magnetic field through energization for adsorbing or repelling a magnetic block one 306 to realize the automatic handling of the container 103. When the electromagnetic plate 303 is energized, it will generate a strong magnetic force to adsorb the magnetic block one 306, making it firmly adhere to the electromagnetic plate 303. Conversely, by adjusting the direction and intensity of the current, the electromagnetic plate 303 can also generate a thrust to push the magnetic block one 306 forward, thereby pushing the container 103 forward. Thus, highly automated operations can be realized through the electromagnetic plate 303, reducing manual intervention.

[0025] Inside the flipping plate 3053, there is a first magnetic block 306. The first magnetic block 306 is magnetically connected to the electromagnetic plate 303. The first magnetic block 306 is made of a strong magnetic material (such as neodymium iron boron). It interacts with the electromagnetic plate 303 through magnetic force to push the container 103. Inside the limit block 404, there is a second magnetic block 407. The second magnetic block 407 is connected to the electromagnetic plate 303. The second magnetic block 407: This is a magnetic component installed inside the limit block 404. The second magnetic block 407 is usually also made of a strong magnetic material (such as neodymium iron boron). It interacts with the electromagnetic plate 303 through magnetic force to realize the rotation and positioning of the limit block 404. When the electromagnetic plate 303 generates the same magnetic force as the second magnetic block 407, it will cause the limit block 404 and the rotating rod 402 to rotate. Finally, the limit block 404 rotates to the position of tilting to the right, ensuring the stability of the container 103 during movement. On the contrary, when generating an opposite magnetic force, it will cause the limit block 404 to tilt to the left.

[0026] Further, the motor 201 drives the lead screw 202 to rotate, driving the sleeve to move along the second slide rail, so that the lifting plate 204 rises or falls to an appropriate height to align with the bottom of the container 103. At the same time, start the motor 3051 to drive the rotating shaft 3052 to rotate, so that the rotating shaft 3052 drives the flipping plate 3053 to rotate to the position in contact with the surface of the container 103. Start the electromagnetic plate 303 to generate magnetic force, adsorb the first magnetic block 306, and cause the first magnetic block 306 to drive the flipping plate 3053 and the moving block 304 to slide forward along the first slide rail 302 and the chute 301, pushing the container 103 forward. Through the magnetic force of the electromagnetic plate 303, the container 103 is pushed to the innermost end inside the loading and unloading platform 1. Then, turn off the electromagnetic plate 303, start the flipping member 305 to rotate the flipping plate 3053 by 90 degrees, and move backward along the first slide rail 302 and the chute 301 by starting the electromagnetic plate 303, so that the flipping plate 3053 moves away from the container 103. Then, start the flipping plate 3053 to rotate. Repeating this way, multiple containers 103 can be pushed into the loading and unloading platform 1. On the contrary, for the flipping member 305, make the flipping plate 3053 contact the container 103 inside the loading and unloading platform 1, and then start the electromagnetic plate 303 to generate a magnetic force of the same polarity as the first magnetic block 306, causing the electromagnetic plate 303 to repel the first magnetic block 306 and push the container 103 to move to the right to complete the unloading work of the container 103. Embodiment

[0027] Refer to Figures 1 - 6 , which is the second embodiment of the new type of the present invention. This embodiment is based on the previous embodiment, and the limit component 4 is arranged inside the lifting plate 204.

[0028] Specifically, a plurality of rotating grooves 401 are formed inside the limiting component 4. A rotating rod 402 is rotatably connected inside the rotating groove 401 through a bearing. Limiting blocks 404 are respectively installed at both ends of the rotating rod 402. An arc-shaped tube 406 is installed inside the rotating groove 401. The arc-shaped tube 406 is filled with electrorheological fluid 4061. Electrorheological fluid 4061 is a kind of intelligent material, whose viscosity can change rapidly under the application of an electric field. It is usually composed of tiny particles dispersed in an insulating liquid. When no electric field is applied, the electrorheological fluid 4061 exhibits low viscosity, similar to an ordinary liquid. When it is necessary to use a power controller to apply an electric field to the electrorheological fluid 4061, it is achieved by applying the voltage to the electrodes through a control circuit for the electrorheological fluid 4061. The tiny particles in the electrorheological fluid 4061 will align along the direction of the electric field, forming a chain-like or columnar structure, resulting in a significant increase in the viscosity of the fluid and becoming close to a solid state. By adjusting the applied electric field strength, the viscosity change degree of the electrorheological fluid 4061 can be precisely controlled, realizing the dynamic regulation of the system rigidity and response characteristics.

[0029] A rigid pad 4062 is installed on the outer surface at the exact center of the arc-shaped tube 406. Elastic pads 4063 are respectively installed on the outer surface of the arc-shaped tube 406 away from the rigid pad 4062. The rigid pad 4062 is made of a high-strength material and has rigid support, providing a stable support point for the rigid pad 4062, ensuring that the limiting block 404 will not be overly deformed when subjected to pressure and maintaining the integrity of the structure. At the same time, in certain operating states, the rigid pad 4062 can help the limiting block 404 accurately stay in a specific position, avoiding unnecessary movement. When the electrorheological fluid 4061 becomes solidified, the rigid pad 4062 and the electrorheological fluid 4061 work together to ensure that the limiting block 404 remains stable in the vertical position and provides a strong support force.

[0030] The elastic pad 4063 is made of an elastic material and can be replaced by materials such as rubber or polyurethane. It has buffering and protection functions. When an impact occurs, the elastic pad 4063 can effectively absorb energy, reducing damage to the equipment and goods and improving the safety of the system. At the same time, the elastic pad 4063 has good deformation ability and can provide a buffering effect when an impact occurs, reducing the damage caused by direct impact to the equipment and goods. The elastic pad 4063 cooperates with the electrorheological fluid 4061 to ensure that the limiting block 404 will not be overly deformed when subjected to pressure and absorb energy when an impact occurs.

[0031] A buffer block 405 is installed between the limit block 404 and the rotating groove 401. The buffer block 405 is made of a buffer elastic material. When the limit block 404 is under pressure, the buffer block 405 can effectively absorb energy, reduce the impact force on other parts of the system, protect the safety of the equipment and goods. At the same time, the buffer block 405 has good deformation ability, can adapt to different contact surface shapes and angles, and provide a more uniform buffer effect. A sliding block 4064 is slidably connected to the outer surface of the arc-shaped tube 406, and the outer surface of the sliding block 4064 is connected to the bottom of the limit block 404.

[0032] Furthermore, the second magnet 407 generates the same magnetic force as the electromagnetic plate 303, causing the limit block 404 and the rotating rod 402 to rotate. Eventually, the limit block 404 rotates to an inclined position. The container 103 continues to move forward and contacts the inclined limit block 404. After the limit block 404 is under pressure, it rotates further, while squeezing the buffer block 405 to absorb the impact force. At the same time, as the limit block 404 moves, the sliding block 4064 slides along the surface of the arc-shaped tube 406, and the electrorheological fluid 4061 is started to be energized through the power controller. After applying an electric field, the electrorheological fluid 4061 approaches the solid state, prompting the electrorheological fluid 4061 to solidify and fix the limit block 404 in the vertical position. When it is necessary to unload the container 103, first turn off the current of the electrorheological fluid 4061, and then start the flipping member 305, so that the flipping plate 3053 pushes the container 103 to move to the right to complete the unloading work of the container 103.

[0033] Working principle: During use, usually the container 103 is first placed on the inclined plate 5 and the loading and unloading platform 1. The motor 201 drives the screw rod 202 to rotate, driving the sleeve to move along the second slide rail, so that the lifting plate 204 rises or falls to an appropriate height to align with the bottom of the container 103. At the same time, start the motor 3051 to drive the rotating shaft 3052 to rotate, so that the rotating shaft 3052 drives the flipping plate 3053 to rotate to a position in contact with the surface of the container 103 (as Figure 1 shown), start the electromagnetic plate 303 to generate a magnetic force, adsorb the first magnet 306, and prompt the first magnet 306 to drive the flipping plate 3053 and the moving block 304 to slide forward along the first slide rail 302 and the chute 301, pushing the container 103 to move forward.

[0034] When the magnetic block two 407 generates the same magnetic force as the electromagnetic plate 303, due to the repulsion between like magnetic poles, the magnetic block two 407 generates an opposite magnetic force, causing the limit block 404 and the rotating rod 402 to rotate. Eventually, the limit block 404 rotates to an inclined position. At the same time, the container 103 continues to move forward and contacts the inclined limit block 404. After the limit block 404 is subjected to pressure, it further rotates and simultaneously squeezes the buffer block 405 to absorb the impact force. At the same time, as the limit block 404 moves, the sliding block 406 slides along the surface of the arc tube 406, and the electrorheological fluid 4061 is activated to conduct electricity through the power controller. After applying an electric field, the tiny particles in the electrorheological fluid 4061 are arranged along the direction of the electric field, forming a chain-like or columnar structure, making the liquid become very viscous, approaching a solid state, and prompting the electrorheological fluid 4061 to solidify to fix the limit block 404 in a vertical position, thereby alleviating the impact force of the container 103 moving forward and ensuring the stability of the container 103. At the same time, the mutual cooperation of the elastic pad 4063 and the rigid pad 4062 can improve the electrorheological fluid 4061's ability to better fix the limit block 404, enabling it to provide a strong supporting force through the high viscosity of the electrorheological fluid 4061, ensuring that the limit block 404 does not move unnecessarily, and thus stably fixing the container 103.

[0035] At the same time, through the magnetic force of the electromagnetic plate 303, the container 103 is pushed to the innermost end inside the loading and unloading platform 1. Then, the electromagnetic plate 303 is turned off, and the flipping member 305 is activated to rotate the flipping plate 3053 by 90 degrees. And by activating the electromagnetic plate 303 to move backward along the slide rail one 302 and the chute 301, the flipping plate 3053 is moved away from the container 103. Then, the flipping plate 3053 is activated to rotate. Repeating this way, multiple containers 103 can be pushed into the loading and unloading platform 1.

[0036] When the container 103 needs to be unloaded, first turn off the current of the electrorheological fluid 4061, then activate the flipping member 305 to make the flipping plate 3053 contact the container 103 inside the loading and unloading platform 1. Then, activate the electromagnetic plate 303 to generate a magnetic force that is the same as that of the magnetic block one 306, prompting the electromagnetic plate 303 to repel the magnetic block one 306, and pushing the container 103 to move to the right. When the container 103 moves, due to the different magnetic forces between the electromagnetic plate 303 and the magnetic block two 407, the electromagnetic plate 303 is attracted to the magnetic block two 407, thereby driving the limit block 404 and the buffer turntable 403 to tilt to the left, buffering through the container 103 to slow down the impact force of the container 103. At the same time, the position and quantity of the rotating groove 401 and the buffer turntable 403 on the lifting plate 204 can be flexibly set according to the size of the container 103 to adapt to containers of different specifications.
