Description

Technical Field

[0001] This utility model relates to a container side-shifting and alignment device, belonging to the field of cargo transfer technology. Background Technology

[0002] A shipping container is a large cargo container. Using shipping containers for transshipment allows goods to be loaded directly at the shipper's warehouse and unloaded at the consignee's warehouse. When changing vehicles or ships en route, there is no need to remove the goods from the container for repackaging. This greatly improves the efficiency of cargo transshipment.

[0003] With the large-scale advancement of automated terminals, higher requirements have been placed on container stacking efficiency. Some terminals require that during the container stacking process, the trolleys and other vehicles have micro-movement translation functions so that the containers can be accurately and automatically placed and positioned without the main unit moving.

[0004] Therefore, a lateral displacement device is needed to achieve automatic container placement and alignment, providing a new solution for improving the efficiency of container loading and unloading at the terminal.

[0005] Currently, cranes such as gantry cranes and rail-mounted cranes have the following disadvantages when grabbing containers:

[0006] When there is a misalignment between the spreader and the container, the trolley needs to be moved to align the spreader with the container's lock hole for lifting.

[0007] When the spreader is misaligned with the container, the trolley needs to be moved to align the spreader with the container's lock hole for lifting.

[0008] When there is an angular error between the spreader and the container, it is necessary to adjust the position and angle of the trailer below to align the spreader with the container, or wait for the spreader to swing freely and then align it with the container's lock hole for lifting.

[0009] In summary, the current container grabbing and positioning system is difficult to adjust, which affects normal handling operations and the efficiency of port yard operations. Utility Model Content

[0010] The purpose of this invention is to solve the technical problems of high difficulty and low efficiency in container gripping and adjustment in the existing technology, and to provide a container side-shifting and alignment device.

[0011] This utility model is achieved through the following technical solution:

[0012] That is, a container side-shifting and alignment device, including a movable frame installed below the crane frame. The movable frame is a rectangular frame structure. The movable frame includes two long crossbeams and two short longitudinal beams. A connecting rib is provided between the two crossbeams. A lateral translation cylinder is hinged to the lower end of the connecting rib. Two longitudinal translation cylinders are hinged to the lower end of one of the crossbeams. The lower ends of the lateral translation cylinder and the longitudinal translation cylinder are hinged to the spreader.

[0013] The lateral translation cylinder and the longitudinal translation cylinder are rotatably hinged to the moving frame.

[0014] This utility model is connected to the upper frame of the crane at the top and to the spreading device at the bottom. When the two longitudinal translation cylinders move towards the trolley, they move the container towards the trolley. When the middle transverse translation cylinder moves towards the main trolley, it moves the container towards the main trolley. When all three translation cylinders move simultaneously, they move the container below diagonally in the horizontal plane. When the two longitudinal translation cylinders move in opposite directions, they rotate the container clockwise or counterclockwise. Using this utility model on-site allows for precise positioning of the spreading device. Compared to adjusting the main trolley and trolley movement, this method achieves faster and more accurate positioning, significantly reduces adjustment time, and improves the stability of the container lifting equipment. The results are excellent.

[0015] Further optimization involves symmetrically arranging two longitudinal translation cylinders located between two transverse translation cylinders, with the connecting rib in the middle as the boundary.

[0016] Further optimization involves fixing two sets of hinge plates on the lower end face of the moving frame beam, each set including two hinge plates. A universal ball with a central through hole is installed inside the front end of the longitudinal translation cylinder rod. A pin is used to pass through the universal ball on the longitudinal translation cylinder and the two hinge plates. The structure is simple and reliable, and the rotation process is smooth.

[0017] Further optimization involves fixing a set of hinge plates on the lower end face of the connecting rib between the two crossbeams of the movable frame. Each set includes two hinge plates. A universal ball with a through hole in the center is installed inside the front end of the hydraulic rod of the transverse translation cylinder. A pin is used to pass through the universal ball on the transverse translation cylinder and the two hinge plates. The structure is simple, reliable, and the rotation process is smooth.

[0018] Further optimization involves installing single-point lasers and cameras at the four corners of the rectangular mobile frame.

[0019] Further optimization involves connecting a single-point laser and a camera to a main controller mounted on the crane body. The automated equipment monitors for container misalignment during alignment, ensuring accuracy. If misalignment is detected, a signal is sent to the main controller, which automatically determines the necessary translation or rotation. Precise positioning using hydraulic cylinders and magnetic rulers enables the translational movement, achieving accurate alignment and closed-loop feedback.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] This utility model is connected to the upper frame of the crane at the top and to the spreading device at the bottom. When the two longitudinal translation cylinders move towards the trolley, they move the container towards the trolley. When the middle transverse translation cylinder moves towards the main trolley, it moves the container towards the main trolley. When all three translation cylinders move simultaneously, they move the container below diagonally in the horizontal plane. When the two longitudinal translation cylinders move in opposite directions, they rotate the container clockwise or counterclockwise. Using this utility model on-site allows for precise positioning of the spreading device. Compared to adjusting the main trolley and trolley movement, this method achieves faster and more accurate positioning, significantly reduces adjustment time, and improves the stability of the container lifting equipment. The results are excellent. Attached Figure Description

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1 , 2The container side-shifting and alignment device shown includes a movable frame 1 installed below the crane frame. The movable frame 1 is a rectangular frame structure. The movable frame 1 includes two long horizontal beams and two short longitudinal beams. A connecting rib is provided between the two horizontal beams. A transverse translation cylinder 6 is hinged to the lower end face of the connecting rib. Two longitudinal translation cylinders 4 are hinged to the lower end face of one of the horizontal beams. The lower ends of the transverse translation cylinder 6 and the longitudinal translation cylinder 4 are hinged to the spreader 2.

[0028] The lateral translation cylinder 6 and the longitudinal translation cylinder 4 are rotatably hinged to the moving frame 1.

[0029] This utility model is connected to the upper frame of the crane at the top and to the spreading device at the bottom. When the two longitudinal translation cylinders 4 move towards the trolley, they move the container towards the trolley. When the middle transverse translation cylinder 6 moves towards the main trolley, it moves the container towards the main trolley. When all three translation cylinders move simultaneously, they move the container below diagonally in the horizontal plane. When the two longitudinal translation cylinders 4 move in opposite directions, they rotate the container clockwise or counterclockwise. By using this utility model on-site, the alignment of the spreading device can be adjusted quickly and accurately compared to adjusting the main trolley and trolley movement. This significantly reduces adjustment time, improves the stability of the container lifting equipment, and demonstrates excellent performance.

[0030] Among them, the two longitudinal translation cylinders 4 are located on the two transverse translation cylinders 6 and are symmetrically arranged with the connecting rib in the middle as the boundary.

[0031] The moving frame 1 has two sets of hinge plates 3 fixedly installed on the lower end face of the crossbeam. Each set includes two hinge plates. The longitudinal translation cylinder 4 has a universal ball with a through hole in the center installed in the front end of the oil rod. A pin 7 is used to pass through the universal ball on the longitudinal translation cylinder 4 and the two hinge plates. The connecting rib between the two crossbeams of the moving frame 1 has a set of hinge plates 5 fixedly installed on the lower end face of the connecting rib. Each set includes two hinge plates. The transverse translation cylinder 6 has a universal ball with a through hole in the center installed in the front end of the oil rod. A pin 7 is used to pass through the universal ball on the transverse translation cylinder 6 and the two hinge plates. The structure is simple and reliable, and the rotation process is smooth.

[0032] Further optimization involves installing single-point lasers and cameras at the four corners of the rectangular mobile frame 1. These lasers and cameras are connected to the main controller mounted on the crane body. The images provided by the automated equipment monitor whether any misalignment occurs during container alignment and whether the alignment is accurate. If misalignment is detected, a signal is sent to the main controller, which automatically determines the necessary translation or rotation action. Precise positioning using hydraulic cylinders and magnetic rulers enables the translation action, achieving accurate container alignment and closed-loop feedback.

[0033] Working principle:

[0034] This utility model is connected to the upper frame of the crane at the top and to the spreading device at the bottom. When the two longitudinal translation cylinders 4 move towards the trolley, they move the container towards the trolley. When the middle transverse translation cylinder 6 moves towards the main trolley, it moves the container towards the main trolley. When all three translation cylinders move simultaneously, they move the container below diagonally in the horizontal plane. When the two longitudinal translation cylinders 4 move in opposite directions, they rotate the container clockwise or counterclockwise. During the adjustment process, the universal ball joint structure makes the rotation very smooth, and the structure is relatively simple. By using this utility model on-site to adjust the alignment of the spreading device, compared with the method of adjusting the main trolley and trolley movement, it can quickly achieve accurate positioning, greatly reduce adjustment time, improve the stability of the container lifting equipment, and has good performance.
