Description

Technical Field

[0001] This utility model relates to the field of port stackers, and in particular to an intelligent stacking mechanism for port empty container stackers. Background Technology

[0002] Port forklifts mainly consist of a power unit, transmission unit, steering unit, working device, hydraulic system, and electrical system. Hydraulic oil from the tank is pumped to the hydraulic cylinders via an oil pump, enabling the lifting and tilting of the forks or spreaders to complete the loading, unloading, and handling of goods. The power unit provides power, the transmission unit transmits power to each working component, the steering unit controls the forklift's direction of travel, the working device directly acts on the goods, the hydraulic system provides power support for the working device's movements, and the electrical system is responsible for controlling and monitoring the operation of the entire equipment.

[0003] Existing port forklift mechanisms, such as the container forklift gantry mechanism and forklift disclosed in patent announcement number CN218754775U, include an outer gantry, an inner gantry, lifting cylinders, and a spreader. The inner gantry is slidably connected to the inner wall of the outer gantry, and the spreader is mounted on the inner gantry. Fixed plates are fixedly connected to the bottom of the outer gantry and the top of the inner gantry. Two lifting cylinders for driving the inner gantry to move within the outer gantry are fixedly connected between the two fixed plates.

[0004] The above solution has the following problems:

[0005] In the stacking of empty containers, if the cargo inside the container is not completely removed and not detected in time, there is a risk of tipping over when using an empty container stacker, posing a safety hazard. Using hydraulic cylinders and hydraulic stations as the lifting power source, malfunctions and leaks can easily have a significant impact on the working environment. (Utility Model Content)

[0006] In the stacking of empty containers, if the cargo inside the container is not completely removed and is not detected in time, there is a risk of tipping over when using an empty container stacker. This utility model provides an intelligent stacking mechanism for port empty container stackers.

[0007] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0008] A smart stacking mechanism for a port empty container stacker includes an outer mast, an inner mast slidably mounted on the inner wall of the outer mast, a spreader mounted on the inner mast, and a drive assembly mounted on the outer mast. The drive assembly is used to lift and lower the spreader. Supports are provided on both sides of the spreader; load cells are mounted on the supports; the load cells are connected to automatic twist locks; the load cells are electrically connected to a processor; and the processor is electrically connected to the drive assembly. By using the load cells, the weight of an empty container can be obtained after it is connected using the automatic twist locks, and this weight information is uploaded to the processor. The processor determines whether the container weight exceeds a rated value. If it does, it sends a command to the drive assembly to stop operation. This allows for timely detection of empty containers and prompt termination of operation, avoiding the risk of tipping over and improving safety.

[0009] Preferably, the support frame has an inverted L-shaped cross-section; the load cell is connected to the support frame via a first screw; the end of the load cell furthest from the support frame is connected to the base of the automatic torsion lock via a second screw. This facilitates the installation of the load cell and the automatic torsion lock.

[0010] Preferably, the support frame is equipped with a limit plate to limit the shaking of the automatic twist lock and facilitate the connection between the automatic twist lock and the container.

[0011] Preferably, the drive assembly includes a motor; the motor is mounted on the inner bottom surface of the outer gantry; the motor output is connected to the input shaft of the screw jack via a first transmission unit; the screw jack is mounted on a base frame; the base frame is fixedly mounted on the inner bottom surface of the outer gantry; a rotating shaft is connected to the upper end of the screw of the screw jack; second transmission units are installed at both ends of the rotating shaft; the second transmission units connect the lifting device and the outer wall of the screw jack. By using a screw jack, the installation of a hydraulic cylinder and hydraulic station is avoided, reducing the chance of environmental pollution. The base frame ensures smooth operation of the screw jack and avoids interference.

[0012] Preferably, the first transmission unit includes a drive sprocket; the drive sprocket is mounted on the motor output shaft; the drive sprocket is connected to a driven sprocket via a first chain; the driven sprocket is mounted on the input shaft of the screw jack.

[0013] Preferably, the second transmission unit includes a transmission sprocket; the transmission sprocket is keyed to the rotating shaft; a second chain is wound around the transmission sprocket; one end of the second chain is fixedly connected to the outer wall of the screw jack, and the other end of the second chain is fixedly connected to the lifting device.

[0014] As can be seen from the above technical solutions, the advantages of this utility model include:

[0015] 1. By setting up weighing sensors, the weight of an empty container can be obtained after it is connected to an automatic twist lock. The weight information is then uploaded to the processor. The processor determines whether the container weight exceeds the rated value. If it does, it sends a command to the drive component to stop the operation. This allows for timely detection of whether the container is empty and timely termination of the operation, avoiding the risk of tipping over and improving safety.

[0016] 2. By designing the screw jack, the installation of hydraulic cylinders and hydraulic stations is eliminated, reducing the likelihood of environmental pollution. The base frame ensures smooth operation of the screw jack and avoids interference. Attached Figure Description
