[0020] The beneficial effects of the present invention are as follows:

[0021] 1. The present invention provides a rotating shaft between the first support plate and the second support plate. When the entire loading and unloading vehicle is loaded with a container and moves, due to the heavy weight of the container, when the loading and unloading vehicle decelerates or turns, the inertia of the container will still cause the container to maintain the momentum in the previous direction of movement. At the moment of deceleration, the traction unit will drive the entire supporting plate 2, the clamping plate mechanism, and the front end of the clamped container to tilt upward. The tilted container will generate backward gravity, which will offset part of the inertia.

[0022] 2. The present invention utilizes an adjustable telescopic rod. When the loading and unloading vehicle rotates, the container's inertia generates centrifugal force that pulls it away from the center of the turning circle. For example, when the vehicle turns left, the centrifugal force is directed to the right, potentially causing the container to tilt to the right or even fall off. Therefore, at the moment of the turn, the telescopic rod inside the turn extends a distance, with the rod closer to the front extending more, while the telescopic rod outside the turn retracts a distance, with the rod closer to the front retracting more. This causes the container to rotate in the opposite direction of the turn. The reaction torque generated by the rotation offsets the counterclockwise deflection caused by the centrifugal force.

[0023] 3. The present invention provides a clamping plate mechanism. Although the telescopic rod and the rotating shaft can offset part of the inertial force and centrifugal force, when the vehicle stops too quickly, the hydraulic device will drive the extension plate to move downward and make the side box flush with the fitting groove. If the container moves forward along the fitting groove due to inertia, it will contact the adsorption rubber and the blocking plate. The spring damper will relieve the inertial force and hinder the continued movement of the container. At the same time, the adsorption rubber will fit with the container. When the spring damper resets the container, the adsorption force will also offset the inertial force generated during the reset process.

[0024] 4. The present invention provides an auxiliary mechanism. The moving block moves laterally and drives the extrusion plate to scrape the surface of the fitting groove on the clamping plate, which will bring out stains. At the same time, in cold weather, due to the high humidity of the port, the fitting groove and the container will be frozen, affecting the normal clamping of the container. The heating device on the extrusion plate will melt the ice layer, making it convenient to squeeze the ice layer and push it out of the fitting groove. At the same time, the frame plate will also fit with the corner of the container, and the poking column will also poke the ice layer, so that the container can be clamped later.

DETAILED DESCRIPTION

[0036] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for specific applications.

[0037] Example 1: Use Figures 1-10 A gantry lift-type loading and unloading vehicle for use in a port according to one embodiment of the present invention is described below.

[0038] like Figure 1-Figure 2 As shown, a gantry lifting loading and unloading vehicle for port use of the present invention includes a symmetrically arranged frame 1, the number of the frames 1 being two, wheels 2 being provided on both sides of the frame 1, main support plates 3 being provided on both sides of the frame 1, the outer surface of the main support plates 3 being slidably connected to a top frame 4, lifting rods 10 being provided on both sides of the frame 1 near the main support plates 3, the top of the lifting rods 10 being fixedly connected to the bottom of the top frame 4, a cockpit 8 being separately provided on one side of the frame 1, the cockpit 8 being provided with a reserve power supply 9, and further comprising:

[0039] A clamping unit 5 provided on the top of the top frame 4 and used to fix and clamp the top of the container, a traction unit 6 provided at both ends of the clamping unit 5, and an auxiliary unit 7 for cleaning and de-icing the clamping unit 5;

[0040] When the present invention is working, the operator controls the entire device in the cockpit 8, first uses the traction unit 6 to lift the container, then pre-processes the container and the clamping unit 5 through the auxiliary unit 7, and finally fixes the container through the clamping unit 5, and drives the entire device to a specific position through the moving wheels, thereby driving the container to move.

[0041] like Figure 3-Figure 5 As shown, the clamping unit 5 includes a hydraulic controller 51, on which telescopic rods 52 are evenly arranged. Each telescopic rod 52 is independently controlled, and the angle between the telescopic rod 52 and the hydraulic controller 51 is adjustable. The output end of the telescopic rod 52 is fixedly connected to a support plate 53, and the center of the support plate 53 is rotatably connected to a rotating shaft 54. The end of the rotating shaft 54 ​​away from the support plate 53 is fixedly connected to a support plate 2 55. The outer surface of the support plate 2 55 is fixedly connected to a clamping mechanism 56 for direct contact with the container.

[0042] The hydraulic controller 51 can control the angle and extension of each telescopic rod 52, and the traction unit 6 can adjust the rotation angle of the rotating shaft 54.

[0043] The outer surface of the hydraulic controller 51 is fixedly connected to the inner wall of the top frame 4, and the lifting rod 10 is used to drive the top frame 4 to move up and down.

[0044] During the movement of the overall loading and unloading truck loaded with containers, due to the heavy weight of the containers, when the loading and unloading truck slows down or turns, the inertia of the containers will still cause the containers to maintain the momentum in the previous direction of movement. At the moment of deceleration, the traction unit 6 will drive the overall support plate 2 55 and the clamping plate mechanism 56 as well as the front end of the clamped container to tilt upward. The tilted container will generate backward gravity, which will offset part of the inertia.

[0045] When the truck rotates, the container's inertia generates centrifugal force that pulls it away from the center of the turn. For example, when the vehicle turns left, the centrifugal force is directed to the right, potentially causing the container to tilt to the right or even fall off. Therefore, at the moment of the turn, telescopic rod 1 52 on the inside of the turn will extend a certain distance, with the closer the telescopic rod 1 52 is to the front, the greater the extension. Meanwhile, telescopic rod 1 52 on the outside of the turn will retract a certain distance, with the closer the telescopic rod 1 52 is to the front, the greater the retraction. This causes the container to rotate in the opposite direction of the turn. The reaction torque generated by the rotation offsets the counterclockwise deflection caused by the centrifugal force.

[0046] Two telescopic rods 58 are symmetrically provided on both sides of the support plate 1 53. The output end of the telescopic rod 58 is fixedly connected to the support plate 3 59. The outer surface of the support plate 3 59 is fixedly connected to the cross block 510. The two sides of the support plate 2 55 are symmetrically provided with cross slots 57 adapted to the cross block 510.

[0047] The second telescopic rod 58 extends and drives the cross block 510 to enter the cross slot 57 to limit the rotation of the second support plate 55.

[0048] like Figure 6-Figure 7 As shown, the clamping plate mechanism 56 includes a clamping plate 561, a fixing groove 562 is provided on the back of the clamping plate 561 for fixed connection with the support plate 2 55, a fitting groove 563 is provided on the front of the clamping plate 561, and the shape of the fitting groove 563 is adapted to the corner of the container, and hydraulic devices 564 are symmetrically provided on both sides of the clamping plate 561, and an extension plate 565 is provided at the bottom of the hydraulic device 564, and the bottom of the extension plate 565 is fixedly connected to the side box 566, and a spring damper 567 is evenly provided inside the side box 566, and one end of the spring damper 567 is fixedly connected to a blocking plate 568, and an adsorption rubber 569 is evenly provided on the side of the blocking plate 568 away from the spring damper 567.

[0049] When it is necessary to clamp the container, the telescopic rod 52 will extend at the same time and drive the fitting groove 563 on the clamping plate 561 to fit the container and fix the container. Although the telescopic rod 52 and the rotating shaft 54 ​​can offset part of the inertia and centrifugal force, when the car stops too quickly, the hydraulic device 564 will drive the extension plate 565 to move down and make the side box 566 flush with the fitting groove 563. If the container moves forward along the fitting groove 563 due to the inertia, it will contact the adsorption rubber 569 and the blocking plate 568. The spring damper 567 will relieve the inertia and hinder the continued movement of the container. At the same time, the adsorption rubber 569 will fit with the container. When the spring damper 567 resets the container, the adsorption force will also offset the inertia generated during the reset process.

[0050] The outer surface of the fixing groove 562 is fixedly connected to the outer surface of the supporting plate 2 55 , and the hydraulic device 564 drives the extending plate 565 to move up and down.

[0051] When the container moves due to inertia, the adsorption rubber 569 will be adsorbed to the side of the container.

[0052] The specific workflow is as follows:

[0053] During operation, when the container is loaded and moves with the loading and unloading truck, due to the heavy weight of the container, when the loading and unloading truck slows down or turns, the inertia of the container will still make the container maintain the momentum in the previous direction of movement. At the moment of deceleration, the traction unit 6 will drive the overall support plate 2 55 and the clamping plate mechanism 56 as well as the front end of the clamped container to tilt upward. The tilted container will generate backward gravity, which will offset part of the inertia. At the same time, at the moment of turning, the telescopic rod 1 52 inside the turn will extend a distance, and the closer the telescopic rod 1 52 is to the front, the greater the amount of extension, while the telescopic rod 1 52 outside the turn will shrink a distance, and the closer the telescopic rod 1 52 is to the front, the more it shrinks. The larger the amount, the container will rotate in the opposite direction of the turn, and the reaction torque generated by the rotation of the object will offset the counterclockwise deflection trend caused by the centrifugal force. However, when the car stops too quickly, the hydraulic device 564 will drive the extension plate 565 to move downward and make the side box 566 flush with the fitting groove 563. If the container moves forward along the fitting groove 563 due to inertia, it will contact the adsorption rubber 569 and the blocking plate 568. The spring damper 567 will relieve the inertia force and hinder the continued movement of the container. At the same time, the adsorption rubber 569 will fit with the container. When the spring damper 567 resets the container, the adsorption force will also offset the inertia force generated during the reset process.

[0054] Example 2: Use Figures 1-10 A gantry lift-type loading and unloading vehicle for use in a port according to one embodiment of the present invention is described below.

[0055] like Figure 8 As shown, a gantry lifting and unloading loading and unloading vehicle for a port of the present invention is based on the first embodiment. The traction unit 6 includes a top plate 61 symmetrically arranged on the top frame 4, and a chain drum 62 is fixedly connected to the top of the top plate 61. A steel cable 65 is stored in the chain drum 62. Drivers 63 are symmetrically arranged at both ends of the chain drum 62. Rollers 64 are provided on the driver 63. The outer surface of the roller 64 is wrapped with the steel cable 65. A bottom rod 66 is provided at the bottom of the steel cable 65, and the bottom rod 66 can be removed.

[0056] When the loading and unloading vehicle moves to the position of the container, it is necessary to manually place the bottom rods 66 at the bottom of both sides of the container, and then the driver 63 drives the rollers 64 to rotate and retract the steel cables 65, thereby lifting the container a certain distance.

[0057] Both ends of the top plate 61 are fixedly connected to the outer surface of the top frame 4, and the bottom rod 66 is placed at the bottom of the container;

[0058] The driver 63 drives the roller 64 to rotate, driving the steel cable 65 to retract and extend.

[0059] like Figure 9As shown, the auxiliary unit 7 includes a support frame 71 symmetrically arranged on the top frame 4, and the outer surface of the support frame 71 on one side is fixedly connected to a servo motor 1 72, and the output end of the servo motor 1 72 is fixedly connected to a rotating rod 73, and support rods 74 are symmetrically arranged on both sides of the rotating rod 73, and the bottom of the support rod 74 is fixedly connected to a support block 77, and a servo motor 2 75 is fixedly connected to the support block 77 on one side, and the output end of the servo motor 2 75 is fixedly connected to a reciprocating screw 78, and the outer surface of the reciprocating screw 78 is threadedly connected to a scraping mechanism 76.

[0060] Before clamping the container, the servo motor 72 drives the rotating rod 73 to rotate, thereby driving the support block 77 and the reciprocating screw 78 to approach the fitting groove 563, and then adjusts the height of the container through the traction unit 6 so that the top corner of the container fits with the shoveling mechanism.

[0061] like Figure 10 As shown, the scraping mechanism 76 includes a moving block 761, the outer surface of the moving block 761 is provided with an extrusion plate 762 whose shape is adapted to the fitting groove 563, a heating device 763 is provided in the extrusion plate 762, and a chemical agent is placed in the heating device 763, and the end of the moving block 761 away from the extrusion plate 762 is fixedly connected to a frame plate 764 adapted to the shape of the corner of the container, and the inner wall of the frame plate 764 is fixedly connected to a poking column 765.

[0062] Servo motor 2 75 will drive the reciprocating screw 78 to rotate, thereby causing the moving block 761 to move laterally and drive the extrusion plate 762 to scratch the surface of the fitting groove 563 on the clamping plate 561, which will bring out the stains. At the same time, when the weather is cold, due to the high humidity of the air in the port, the fitting groove 563 and the container will be frozen, affecting the normal clamping of the container. The heating device 763 on the extrusion plate 762 will melt the ice layer, making it convenient to squeeze the ice layer and push the ice out of the fitting groove 563. At the same time, the frame plate 764 will also fit with the corner of the container, and the poking column 765 will also poke the ice layer, so that the container can be clamped later.

[0063] The top of the support frame 71 is fixedly connected to the outer surface of the top frame 4 , and the inner wall of the moving block 761 is threadedly connected to the outer surface of the reciprocating screw rod 78 .

[0064] The specific workflow is as follows:

[0065] During operation, before clamping the container, servo motor 1 72 will drive the rotating rod 73 to rotate, thereby driving the support block 77 and the reciprocating screw rod 78 to approach the fitting groove 563, and then the height of the container is adjusted by the traction unit 6 so that the top corner of the container fits with the shoveling mechanism. Then, servo motor 2 75 will drive the reciprocating screw rod 78 to rotate, thereby causing the moving block 761 to move laterally and drive the squeezing plate 762 to scratch the surface of the fitting groove 563 on the clamping plate 561, which will bring out the stains. At the same time, in cold weather, due to the high humidity of the port, the fitting groove 563 and the container will be frozen, affecting the normal clamping of the container. The heating device 763 on the squeezing plate 762 will melt the ice layer, making it convenient to squeeze the ice layer and push the ice out of the fitting groove 563. At the same time, the frame plate 764 will also fit with the corner of the container, and the poking column 765 will also poke the ice layer, so that the container can be clamped later.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field and related fields without making creative efforts should fall within the scope of protection of the present invention.
