Description

Technical Field

However, during the loading and unloading process of containers, especially when transferring between different means of transportation such as ships, trains or trucks, how to quickly and accurately align and safely lift the containers has become a key technical problem; traditional container lifting methods mainly rely on standard lifting equipment equipped with cranes, such as four-point lifting equipment. This lifting equipment is connected to the corner fittings on the top of the container through locking devices on the four corners to complete the initial alignment steps, and then the crane completes the lifting task of the container.

[0003] Patent publication number CN114634096A discloses an auxiliary alignment device for container lifting equipment. The patent uses the cooperation between the infrared sensor, fixed frame, elastic member, movable frame, protective frame and explosion-proof glass to emit laser through the infrared sensor, so that the laser is irradiated on the container. When it is detected that the laser is irradiated on the four corners of the container, the lifting clamp can fix the container to facilitate the lifting of the container.

[0033] When in use, the container 101 is first transported to the designated location by a transport vehicle, and then the limit of the container 101 is released on the transport vehicle, and then the lifting rope of the crane is connected to the upper side of the sliding frame 16, and then the sliding frame 16 and the frame 1 are lifted by the crane, and the sliding frame 16 and the frame 1 are transferred to the top of the container 101, and then the second servo motor 701 drives the screw rod 702 to rotate, so that the screw rod 702 drives the lifting frame 6, the guide plate 8 and the electric push rod 9 to descend, so that the bottom of the lifting frame 6 is lower than the bottom end of the tetrahedron 3 (so that the lifting frame 6 can contact the container 101 before the tetrahedron 3), and then the telescopic rod of the electric push rod 9 is controlled to extend, so that the telescopic rod of the electric push rod 9 pushes the guide plate 8 to rotate, so that the guide plate The bottom surface of the guide plate 8 forms an inclined surface (the side of the guide plate 8 close to the lifting frame 6 is the high point, and the side of the guide plate 8 away from the lifting frame 6 is the low point), and then the sliding frame 16 and the frame 1 are gradually lowered by a crane, so that the frame 1 drives the first servo motor 2, the tetrahedron 3, the connecting frame 4, the guide rail 5, the lifting frame 6, the guide plate 8, the closing frame 10, the gas cylinder 1201 and the piston 1202 to descend, so that the frame 1 gradually approaches the container 101 on the transport vehicle. When the inclined surface at the bottom of the guide plate 8 contacts the container 101, the container 101 will squeeze the guide plate 8, so that the guide plate 8, the lifting frame 6, the guide rail 5, the frame 1, the first servo motor 2 and the tetrahedron 3 are moved and adjusted, so that the tetrahedron 3 can be just aligned with the corner piece 1 on the container 101. 02, thereby automatically aligning the tetrahedron 3 with the corner fitting 102 on the container 101. When the frame 1 continues to descend, the connecting frame 4 and the tetrahedron 3 on the frame 1 will enter the corner fitting 102 on the container 101. When the piston 1202 contacts the corner fitting 102 on the container 101, the corner fitting 102 will squeeze the piston 1202 to move upward, and the spring 1203 is compressed, so that the piston 1202 squeezes the air in the air storage cylinder 1201, so that the air in the air storage cylinder 1201 enters the air bag 11 through the second air pipe 1204, and then the air bag 11 gradually expands, so that the air bag 11 seals the outer side of the connecting frame 4 and the inner wall of the corner fitting 102 through expansion. When the sealing gasket at the bottom of the closing frame 10 and the top of the corner fitting 102 are closed, the sealing gasket at the bottom of the closing frame 10 and the top of the corner fitting 102 are closed. When the bottom of the closed frame 10 contacts the top of the corner piece 102, a sealed space is formed between the bottom of the closed frame 10 and the top of the corner piece 102. Then, the crane is used to stop lowering the sliding frame 16 and the frame 1, and the air pump 13 is started to evacuate the air in the closed frame 10 through the first air pipe 14 to reduce the air in the sealed space. During this period, the air pressure in the closed frame 10 is continuously detected by the barometer 15. After a period of time, the air pump 13 is turned off, and then the detection data of the barometer 15 is used to judge. If the air pressure detection data of the barometer 15 is the same as the external air pressure, it means that there is a crack in the top of the corner piece 102 causing ventilation. At this time, the subsequent lifting operation is stopped, and the sliding frame 16 and the frame 1 are lifted by the crane. Then, the corner piece 102 with cracks on the container 101 is replaced.Then repeat the above operation to detect the new corner piece 102; if the air pressure detection data of the barometer 15 is smaller than the external air pressure, it means that there is no crack on the top of the corner piece 102, and the subsequent lifting operation can be carried out. Then, the first servo motor 2 drives the tetrahedron 3 to rotate forty-five degrees, so that the tetrahedron 3 is stuck in the corner piece 102, and then the sliding frame 16 and the frame 1 are lifted by the crane, and the corner piece 102 and the container 101 can be lifted by the tetrahedron 3, so that the container 101 leaves the transport vehicle;,

[0034] Then, the container 101 is lifted to the top of the designated position by a crane, and the sliding frame 16 and the frame 1 are gradually lowered by the crane, so that the container 101 falls at the designated position, and then the first servo motor 2 drives the tetrahedron 3 to rotate 45 degrees in the opposite direction to reset, so that the tetrahedron 3 is loosened in the corner piece 102, and then the air pump 13 draws air into the closed frame 10 through the first air pipe 14 until the air pressure in the closed frame 10 returns to normal, and then the sliding frame 16 and the frame 1 are lifted by the crane, so that the frame 1 drives the first servo motor 2, the tetrahedron 3, the connecting frame 4, the guide rail 5, the lifting frame 6, the guide plate 8, the closed frame 10, the air storage cylinder 1201 and the piston 1202 to rise, so that the frame 1 gradually moves away from the container 101. , thereby making the tetrahedron 3 and the connecting frame 4 leave the corner fitting 102, and making the sealing gasket at the bottom of the closing frame 10 separate from the top of the corner fitting 102. When the piston 1202 is separated from the corner fitting 102 on the container 101, the spring 1203 returns to its original state, and the spring 1203 drives the piston 1202 to move downward and reset, so that the closing frame 10 draws out the air in the airbag 11 through the second air pipe 1204, so that the airbag 11 gradually shrinks and resets, and then controls the telescopic rod of the electric push rod 9 to shorten, so that the telescopic rod of the electric push rod 9 pulls the guide plate 8 to reverse and reset, and finally drives the screw rod 702 to reverse and reset through the second servo motor 701, so that the screw rod 702 drives the lifting frame 6, the guide plate 8 and the electric push rod 9 to rise and reset.

[0035] See also Fig. 9 and Fig.10As shown, a horizontal mechanism is also included, which includes an inclination sensor 17, a controller 18 and a driving member; an inclination sensor 17 is arranged on the upper side of the sliding frame 16; a controller 18 is installed in the middle of the lower side of the sliding frame 16, and the inclination sensor 17 is electrically connected to the controller 18; a driving member is also arranged on the sliding frame 16, and the driving member includes a third servo motor 19, a first gear 20 and a rack 21, and the third servo motor 19 is arranged on the front and rear sides of the lower side of the sliding frame 16, and the third servo motor 19 is electrically connected to the controller 18, and the output shaft of the third servo motor 19 rotatably passes through the sliding frame 16, and the first gear 20 is connected to the output shaft of the third servo motor 19, and the front and rear sides of the inner side of the frame 1 are connected to the rack 21, and the first gear 20 is meshed with the rack 21.

[0036] When the crane lifts the container 101 through the sliding frame 16 and the frame 1, it can be sensed by the inclination sensor 17. When the inclination sensor 17 senses the tilt, the inclination sensor 17 will send a signal. After receiving the signal, the controller 18 will control the third servo motor 19 to drive the first gear 20 to rotate forward or reverse according to the situation. If the inclination sensor 17 senses a tilt that is lower on the left and higher on the right, the controller 18 will control the third servo motor 19 to drive the first gear 20 to rotate forward, so that the first gear 20 drives the rack 21 and the frame 1 to move to the right, so that the sliding frame 16, the frame 1 and the container 101 gradually become horizontal, thereby protecting the goods in the container 101. If the inclination sensor 17 senses a tilt that is higher on the left and lower on the right, the controller 18 will control the third servo motor 19 to drive the first gear 20 to reverse, so that the first gear 20 drives the rack 21 and the frame 1 to move to the left, so that the sliding frame 16, the frame 1 and the container 101 gradually become horizontal.

[0037] See also Fig.11 As shown, it also includes a lifting mechanism, which includes a dual-axis motor 22, a rotating plate 23, a friction block 24 and a transmission member; the two dual-axis motors 22 are symmetrically installed on the sliding frame 16 front and back; the two rotating plates 23 are symmetrically installed on the sliding frame 16 front and back, and the two dual-axis motors 22 are located between the two rotating plates 23; the upper parts of the two rotating plates 23 on the side away from each other are connected with friction blocks 24, and the friction blocks 24 are used to contact the side of the container 101 so as to lift the side of the container 101 through friction; the transmission member includes a second gear 25 and a third gear 26, the second gear 25 is connected to the output shafts on the left and right sides of the dual-axis motor 22, and the third gear 26 is symmetrically arranged on the left and right sides of the rotating plate 23, and the second gear 25 is meshed with the third gear 26.

[0038] When the crane lifts the container 101 through the sliding frame 16 and the frame 1, and the sliding frame 16, the frame 1 and the container 101 are in a horizontal state by adjusting the horizontal mechanism, the dual-axis motor 22 can be used to drive the turn plate 23 to rotate through the transmission of the second gear 25 and the third gear 26 until the friction block 24 on the turn plate 23 contacts the side of the container 101, so that the friction block 24 can lift the side of the container 101 through friction, thereby stabilizing the middle area of ​​the container 101 to prevent the middle area of ​​the container 101 from sinking; thereafter, when the container 101 falls at the designated position, the dual-axis motor 22 is used to drive the turn plate 23 to reverse and reset through the transmission of the second gear 25 and the third gear 26, so that the friction block 24 on the turn plate 23 is separated from the side of the container 101.

[0039] See also Fig.11 As shown, a distance sensor 27 is also included; two distance sensors 27 are installed symmetrically on the frame 1, and the distance sensor 27 is used to sense the distance between the front of the transport vehicle, and the distance sensor 27 is electrically connected to the controller 18.

[0040] By setting the distance sensor 27, when the crane lifts the container 101 through the sliding frame 16 and the frame 1, the distance sensor 27 will also rise synchronously with the frame 1. During this period, the distance sensor 27 on one side is used to continuously sense the distance between the container and the front of the transport vehicle and send a signal. After receiving the signal, the controller 18 will compare it. If the distance sensor 27 senses that the distance between the front of the transport vehicle is constantly increasing, it is a normal situation. If the distance sensor 27 senses that the distance between the front of the transport vehicle has not changed, it is an abnormal situation. At this time, the controller 18 will stop the lifting operation and then control the crane to lower the container 101 through the sliding frame 16 and the frame 1. At the same time, the controller 18 will send a notification to the operator, so that the operator can check whether the limit of the container 101 of the transport vehicle has not been released after receiving the notification, so as to prevent the container 101 from being lifted up with the transport vehicle due to the failure to release the limit. After that, after the operator has completed the inspection and ensured that the limit of the container 101 has been released, the controller 18 will continue the lifting operation.
