Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0031] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.
[0032] In order to solve the problems mentioned in the background art, Figure 1 A schematic diagram of the composition of a port container handling machine provided in this embodiment of the present invention is shown below. Figure 1 The port container handling machinery 100 includes a boom status acquisition module 101, a speed control component 102, a power controller 103, a gearbox 104, and a drive motor 105. The boom status acquisition module 101 is connected to the boom of the port container handling machinery 100 and can detect the boom's status parameters. The speed control component 102 is located near the operator's seat and can generate speed control signals based on user operation. The power controller 103 is connected to the speed control component 102, the boom status acquisition module 101, the drive motor 105, and the gearbox 104, and can adjust the gear of the gearbox 104 according to the status parameters and adjust the speed of the drive motor 105 according to the speed control signals.
[0033] Specifically, the port container mobile handling machinery 100 is an important piece of equipment used for lifting and handling cargo in port operations. It includes a crane part and a moving part. The crane part includes a pump motor and a lifting arm with a spreader or grab at the top. The pump motor is connected to the lifting arm and provides power for the clamping and releasing of the spreader or grab, as well as the extension, retraction, and rotation of the lifting arm. The moving part refers to the base of the port container mobile handling machinery 100, which can drive the lifting and handling part to move. For example, the moving part can be a floating platform, a rail-mounted platform, a wheeled platform, or a tracked platform.
[0034] The boom status acquisition module 101 refers to a sensing and status analysis component capable of acquiring the working status of the boom. The boom status acquisition module 101 can be installed on or connected to the boom, and can detect the boom's status parameters. For example, the boom's status parameters may include the height of the spreader above the ground and / or the spreader's load capacity. Correspondingly, the boom status acquisition module 101 may include a spreader height acquisition device and a boom load capacity acquisition device.
[0035] Both the drive motor 105 and the gearbox 104 belong to the moving parts of the port container handling machinery 100. The drive motor 105 provides power to the moving parts of the port container handling machinery; for example, the drive motor 105 may include an AC asynchronous motor or a permanent magnet motor. The gearbox 104 mainly consists of basic components such as gear sets, shafts, bearings, and synchronizers, and can transmit the power of the drive motor 105 to the wheels according to a preset gear ratio (i.e., gear). The gearbox 104 is a multi-speed gearbox with variable gear ratios, and the gear ratios of the gearbox 104 can be controlled by the power controller 103.
[0036] Speed control component 102 refers to a vehicle speed control component capable of generating speed control signals and gear shifting signals based on the driver's speed adjustment operations. For example, speed control component 102 may include a gear shifter, a speed pedal, and a brake pedal. Power controller 103, also known as a vehicle control unit (VCU), coordinates and controls the working state of the moving parts on the port container handling machinery 100. Power controller 103 is connected to speed control component 102, boom status acquisition module 101, drive motor 105, and gearbox 104, respectively. Power controller 103 can control the rotational speed of drive motor 105 and the gear ratio of gearbox 104 according to the speed control signals and gear shifting signals uploaded by speed control component 102. Power controller 103 can also adjust the gear ratio of gearbox 104 according to the boom status parameters fed back by boom status acquisition module 101, so that the gear position of gearbox 104 is associated with the boom status.
[0037] The port container handling machinery provided in this embodiment is equipped with a boom status acquisition module, a speed control component, a power controller, a gearbox, and a drive motor. The boom status acquisition module is connected to the boom of the port container handling machinery and can detect the boom's status parameters. The speed control component is located near the operator's seat and can generate speed control signals based on user operations. The power controller is connected to the speed control component, the boom status acquisition module, the drive motor, and the gearbox, respectively. It can adjust the gearbox gear according to the status parameters and adjust the drive motor speed according to the speed control signals, thus achieving adjustment of the moving speed and gearbox gear. This links the gearbox gear to the boom's height and weighing status, improving the machinery's operational safety.
[0038] Optionally, Figure 2 This is a schematic diagram of another type of container handling machinery for ports provided in this embodiment. Based on the aforementioned embodiment, refer to... Figure 2 The boom status acquisition module 101 includes a spreader height detection unit 201. The spreader height detection unit 201 is installed on the spreader and can measure the height of the spreader above the ground.
[0039] Specifically, the lifting device height detection unit 201 can be a height sensor, which is installed on the lifting device of the lifting arm and can directly collect the height of the lifting device above the ground. For example, the lifting device height detection unit 201 can include at least one of a laser height measuring instrument, an ultrasonic height measuring instrument, a level, a total station, and a photoelectric height measuring instrument.
[0040] For example, during the operation of container handling machinery in a port, a laser height measuring device installed on the spreader can detect the spreader's height above the ground and provide feedback to the power controller 103. The power controller 103 monitors whether the spreader's height above the ground exceeds a preset height. Once the spreader's height exceeds the preset height, the power controller 103 controls the gearbox 104 to lock in a low gear and will not adjust the gearbox 104 to a higher gear based on user operation, until the spreader's height above the ground falls below the preset height. This gear locking scheme ensures that the machinery's movement gear is negatively correlated with the spreader's height above the ground, preventing rapid movement of the machinery when the cargo is held high and ensuring the safety of loading and unloading operations.
[0041] Optionally, Figure 3 This is a schematic diagram illustrating the composition of another type of container mobile handling machinery for ports provided in this embodiment. Figure 4 This is a schematic diagram illustrating the detection principle of the lifting height of a lifting device, based on the aforementioned embodiments and combined with... Figure 3 and Figure 4The container handling equipment 100 for ports also includes a pump motor 301, which is connected to the lifting boom and can drive the boom to rotate and extend. The boom status acquisition module 101 includes a spreader height detection unit 201. The spreader height detection unit 201 is connected to the pump motor 301 and can determine the height of the spreader off the ground based on the working status of the pump motor 301.
[0042] Specifically, the pump motor 301 can be connected to the hydraulic cylinder on the lifting arm. By actuating the hydraulic valve on the hydraulic cylinder, the extension, retraction, and rotation of the lifting arm are achieved. Rotation refers to the lifting arm rotating in a vertical plane. During rotation, the angle between the extension direction of the lifting arm and the ground changes, i.e., the rotation angle X of the lifting arm changes. For example, the pump motor 301 may include a plunger pump. The spreader height detection unit 201 can be a data processing chip or a data processor, connected to the pump motor 301. It can determine the height of the spreader above the ground based on the operating state of the pump motor 301. For example, the operating state of the pump motor 301 may include the rotation angle X and the extension length H2 provided to the lifting arm.
[0043] For example, based on the operating status such as the rotation angle of the pump motor 301, the spreader height detection unit 201 can determine the rotation angle X provided by the pump motor to the lifting arm. Combining the extension length L of the lifting arm and the height H2 of the lifting arm above the ground, the spreader height detection unit 201 can calculate the height H1 of the spreader above the ground and feed it back to the power controller 103. The power controller 103 monitors whether the height H1 of the spreader above the ground exceeds the preset height. Once the height H1 of the spreader above the ground exceeds the preset height, the power controller 103 controls the gearbox 104 to lock in a low gear and will not shift up the gear according to the user's operation until the height H1 of the spreader above the ground falls below the preset height. This gear locking scheme makes the movement gear of the machinery negatively correlated with the height H1 of the spreader above the ground, preventing rapid movement of the machinery when the goods are raised high and ensuring the safety of loading and unloading operations.
[0044] Optionally, Figure 5 This is a schematic diagram of another type of container handling machinery for ports provided in this embodiment. Based on the aforementioned embodiments, refer to... Figure 5 The boom status acquisition module 101 includes a weight acquisition unit 501. The weight acquisition unit 501 is mounted on the spreader and is capable of acquiring the weight of the cargo held by the spreader.
[0045] Specifically, the weight acquisition unit 501 can be a weight sensor, which can be installed on the spreader to directly measure the weight data of the goods held by the spreader. For example, the weight acquisition unit 501 includes a strain gauge sensor, which can measure the force borne by the spreader according to the deformation of the spreader, thereby realizing the acquisition of the weight of the goods held by the spreader.
[0046] For example, during the operation of the container mobile handling machinery 100 in the port, the weight acquisition unit 501 can collect the weight of the cargo held by the spreader in real time and feed it back to the power controller 103. The power controller 103 monitors whether the weight of the cargo exceeds the preset weight. Once the weight of the cargo exceeds the preset weight, the power controller 103 controls the gearbox 104 to lock in a low gear and will not adjust the gearbox 104 to a higher gear according to the user's operation, until the lifting weight of the spreader is below the preset weight. This gear locking scheme makes the movement gear of the machinery negatively correlated with the weight of the lifted cargo, preventing rapid movement of the machinery under heavy load and ensuring the safety of loading and unloading operations.
[0047] Optionally, Figure 6 This is a schematic diagram of another type of container handling machinery for ports provided in this embodiment. Based on the aforementioned embodiments, refer to... Figure 6 The container handling equipment 100 for ports also includes a pump motor 301, which is connected to the lifting arm and can drive the lifting arm to rotate and extend. The lifting arm status acquisition module 101 includes a weight acquisition unit 501; the weight acquisition unit 501 is connected to the pump motor 301 and can determine the weight of the cargo held by the spreader based on the working status of the pump motor 301.
[0048] Specifically, the pump motor 301 can be connected to the hydraulic cylinder on the lifting arm. By actuating the hydraulic valve on the hydraulic cylinder, the extension, retraction, and rotation of the lifting arm are achieved. Rotation refers to the lifting arm rotating in a vertical plane, during which the angle between the extension direction of the lifting arm and the ground changes. For example, the pump motor 301 may include a piston pump. The weight acquisition unit 501 is connected to the pump motor 301 and determines the weight held by the lifting device by analyzing the operating status data of the pump motor 301, such as load power, load current, and output torque. For example, the weight acquisition unit 501 can be connected to the hydraulic system corresponding to the pump motor 301, indirectly measuring the weight of the cargo held by the lifting device by measuring the pressure of the hydraulic oil.
[0049] For example, during the operation of the container mobile handling machinery 100 in the port, the weight acquisition unit 501 can determine the weight of the cargo held by the spreader in real time based on the load power of the pump motor 301 and feed it back to the power controller 103. The power controller 103 monitors whether the weight of the cargo exceeds the preset weight. Once the weight of the cargo exceeds the preset weight, the power controller 103 controls the gearbox 104 to lock in a low gear and will not adjust the gearbox 104 to a higher gear according to the user's operation until the lifting weight of the spreader is below the preset weight. This gear locking scheme makes the movement gear of the machinery negatively correlated with the weight of the lifted cargo, preventing rapid movement of the machinery under heavy load and ensuring the safety of loading and unloading operations.
[0050] Optionally, Figure 7 This is a schematic diagram of another type of container handling machinery for ports provided in this embodiment. Based on the aforementioned embodiments, refer to... Figure 7 The port container handling equipment 100 also includes a control panel 601 and a remote communication module 602. The control panel 601 is connected to the power controller 103 and can display the gear position of the gearbox 104 and the speed of the drive motor 105. The remote communication module 602 is connected to the power controller 103 and also has a wireless communication connection with a server. The remote communication module 602 can upload the working log of the power controller 103 to the server.
[0051] Specifically, the control panel 601 can be a display screen that shows the gear position of the gearbox 104 and the speed of the drive motor 105, allowing users to obtain the machine's status information at any time. The remote communication module 602 can be a Bluetooth module, a cellular network module, a WIFI module, or a ZigBee module, enabling wireless communication between the mobile machinery and the server, facilitating the uploading of machine status parameters and the server's scheduling of the machinery.
[0052] This utility model also provides a container mobile handling system for ports. Figure 8 This is a schematic diagram of the composition of a port container handling system provided in an embodiment of the present invention. Based on the foregoing embodiments, refer to... Figure 8 The port container mobile handling system 800 includes a server 801 and multiple port container mobile handling machines 100. The server 801 is wirelessly connected to each port container mobile handling machine 100.
[0053] This utility model provides a port container mobile handling machinery and system, which includes a boom status acquisition module, a speed control component, a power controller, a gearbox, and a drive motor. The boom status acquisition module is connected to the boom of the port container mobile handling machinery and can detect the boom's status parameters.
