Description

Technical Field

[0001] This utility model relates to the field of container positioning technology, specifically to a space-saving container self-positioning device. Background Technology

[0002] Container handling at port terminals requires the operation of quay cranes to grab containers from ships and transfer them to container truck pallets located below the cranes. During the placement of containers onto the truck pallets, the containers often sway in mid-air due to inertia or wind, making it difficult to accurately align them with the pallet's locking mechanism and impacting operational efficiency. Existing positioning devices, when no containers are placed on them, have their positioning arms in a free state, occupying a significant amount of floor space and hindering normal operation. Utility Model Content

[0003] This utility model addresses the existing technical problems by providing a space-saving container self-positioning device.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A space-saving container self-positioning device includes a pallet frame and a drive mechanism. The pallet frame is provided with multiple positioning locks and multiple self-positioning components. The self-positioning components include a positioning arm, a bottom pallet, and a side clamp. The positioning arm is hinged to the pallet frame via a pin. The bottom pallet is installed at one end of the positioning arm, and the side clamp is installed at the other end of the positioning arm. A counterweight is installed on the positioning arm, and the counterweight is located at the same end as the bottom pallet. Multiple limiting plates are installed on the pallet frame, and the limiting plates correspond to the positioning arm. The drive mechanism is used to drive the positioning arm to rotate to the positioning state.

[0005] Based on the above technical solution, the present invention can be further improved as follows:

[0006] Preferably, the pallet frame is provided with a plurality of U-shaped through grooves in the circumference, and the two ends of the pin are installed on the side wall of the U-shaped through groove, the size of the U-shaped through groove being larger than the size of the bottom pallet.

[0007] Preferably, a plurality of the self-positioning components are symmetrically arranged on the pallet frame.

[0008] Preferably, the bottom tray is hinged to the positioning arm via a spherical joint, and the side gripper is hinged to the positioning arm via a spherical joint.

[0009] Preferably, the side clamp is a disc vibrator.

[0010] Preferably, the system further includes a plurality of first winches, each corresponding to the positioning arm. The positioning arm is provided with lugs, which are located on the same side of the pin as the side clamp. The first winches are connected to the lugs via ropes.

[0011] Preferably, it further includes a second winch, rollers, and a reversing wheel. The second winch is located at the bottom center of the pallet frame. The rollers and the reversing wheel are installed at the bottom of the pallet frame. The rope of the second winch passes through the reversing wheel and the rollers and is connected to a lug on the positioning arm. The lug and the side clamp are located on the same side of the pin.

[0012] The beneficial effects of this utility model are as follows: In its natural state, the positioning arm rotates to a vertical position under the action of the counterweight, reducing the floor space occupied and avoiding interference between the positioning arm and other objects; when the container is lowered onto the pallet frame, the bottom wall of the container touches the bottom pallet of each self-positioning component, and the continued descent can drive the positioning arm to rotate, and the side grippers of each positioning arm contact the side wall of the container, so that while the container is falling, the side grippers push the container to move towards the center position of the pallet frame. When the container contacts the upper surface of the pallet, the lock hole of the container is aligned with the positioning lock head on the pallet frame. The lowering process does not require precise alignment with the positioning lock head on the pallet frame, reducing the difficulty of operation and improving the efficiency of operation.

[0024] Example 1

[0025] Reference Figures 1 to 5 As shown, this utility model discloses a space-saving container self-positioning device, including a pallet frame 1 and a drive mechanism. The pallet frame 1 is mounted on a support column (not shown in the figure). The pallet frame 1 is provided with multiple positioning locks 2 and multiple self-positioning components. The self-positioning components include a positioning arm 3, a bottom tray 5, and a side clamp 6. The positioning arm 3 is hinged to the pallet frame 1 through a pin 4. The bottom tray 5 is mounted on one end of the positioning arm 3 and is located inside the positioning arm 3. The side clamp 6 is mounted on the other end of the positioning arm 3. A counterweight 7 is mounted on the positioning arm 3 and is located at the same end as the bottom tray 5. Multiple limiting plates 8 are mounted on the pallet frame 1. The limiting plates 8 correspond to the positioning arm 3 and are used to limit the horizontal or vertical position of the positioning arm 3. The drive mechanism is used to drive the positioning arm 3 to rotate to the positioning state.

[0026] The positioning arm 3 includes an inner arm 3.1, a connecting arm 3.2, and an outer arm 3.3. One end of the connecting arm 3.2 is connected to the inner arm 3.1, and the other end is connected to the outer arm 3.3. The bottom tray 5 is mounted on the inner arm 3.1, and the side gripper 6 is mounted on the outer arm 3.3. In its natural state, the positioning arm 3 is in a vertical position under the action of the counterweight 7, that is, the connecting arm 3.2 is in a vertical position, and the positioning arm 3 is in contact with the limiting plate 8. Figure 2 As shown, the bottom tray 5 and the side clamp 6 are located within the projection range of the tray frame 1, reducing the floor space. When the positioning arm 3 is in the positioning state under the action of the drive mechanism, that is, when the connecting arm 3.2 is in a horizontal state, refer to... Figure 3 As shown, the bottom pallet 5 protrudes upward from the pallet frame 1, so that when the container 14 is lowered, the bottom wall of the container 14 can make normal contact with the bottom pallet 5, and drive the positioning arm 3 to rotate, so that the side clamp 6 moves towards the container 14 and applies force to the container 14, so that the container 14 moves towards the center of the bracket body 1, realizing the automatic positioning of the positioning hole and the positioning lock head 2 of the container 14, and clamping the container 14 to ensure the stability of the container 14 and improve the operation efficiency.

[0027] Furthermore, the bottom pallet 5 is hinged to the positioning arm 3 via a spherical joint, and the side clamp 6 is also hinged to the positioning arm 3 via a spherical joint. The side clamp 6 is a clamping disc. Both the bottom pallet 5 and the side clamp 6 can rotate at a certain angle, allowing them to better adapt to various states of the container 14, improving the fit between the bottom pallet 5 and the side clamp 6 and the container 14, preventing jamming, and further improving operational efficiency.

[0028] In this embodiment, the pallet frame 1 is provided with four positioning lock heads 2, located at the four corners of the pallet frame 1. The pallet frame 1 has multiple U-shaped slots along its circumference. The two ends of the pins 4 are mounted on the side walls of the U-shaped slots. The size of the U-shaped slots is larger than the size of the bottom pallet 5, ensuring that the bottom pallet 5 can move smoothly under the pallet frame 1, reducing space occupation. Specifically, the pallet frame 1 has six U-shaped slots along its circumference, with each U-shaped slot corresponding to a self-positioning component. One self-positioning component is located at each end of the length direction of the pallet frame 1, and two self-positioning components are located on each side of the pallet frame 1. The self-positioning components are symmetrically arranged on the pallet frame 1 to ensure the self-positioning effect of the container 14.

[0029] In this embodiment, the drive mechanism includes multiple first winches 9, the positions and numbers of which correspond to the positioning arms 3, enabling separate control of different positioning arms 3 and improving flexibility during use. The first winches 9 are located on the outer side of the positioning arms 3, and each positioning arm 3 has a lug 10. The lug 10 and the side clamp 6 are located on the same side of the pin 4. The first winches 9 are connected to the lug 10 via ropes to control the positioning arms 3.

[0030] The usage process is as follows: Before placing container 14, the first winch 9 retracts the rope, pulling the positioning arm 3 to rotate to the positioning state. At this time, the connecting arm 3.2 of the positioning arm 3 is in a horizontal state, and the positioning arm 3 is in contact with the limiting plate 8. (Refer to...) Figure 3 As shown, during the placement of container 14, the first winch 9 is unpowered. During the self-centering process of container 14's descent, the first winch 9 passively releases the rope until container 14 is placed on the pallet frame 1. The side gripper 6 then clamps and positions container 14. (Refer to...) Figure 5 As shown.

[0031] During the process of container 14 leaving pallet frame 1, the positioning arm 3 remains in a constant state. When the height of the bottom wall of container 14 is greater than that of the side clamp 6, i.e., container 14 has completely left pallet frame 1: if the operation ends, the positioning arm 3 rotates to a vertical state under the action of the counterweight 7, and the first winch 9 continuously releases the rope to reduce the occupied area; if the operation continues, the first winch 9 performs a rope winding action to pull the positioning arm 3 to the positioning state, i.e., the horizontal state, so that the next container 14 can achieve self-positioning.

[0032] In an optional embodiment, the side clamp 6 is a disc vibrator. When the container 14 is placed on the pallet frame 1, it is clamped by the disc vibrator. When the disc vibrator vibrates, the bulk cargo piled on one side of the container 14 slides off, achieving a uniform weight distribution of the container 14. This is suitable for containers 14 loaded with bulk cargo, preventing the container 14 from being unbalanced during sea transport or causing it to overturn during truck transport, thus improving the safety of the container 14 during transport.

[0033] Example 2

[0034] Reference Figures 6 to 8 As shown, in this embodiment, the drive mechanism includes a second winch 11, a roller 12, and a reversing wheel 13. The second winch 11 is located at the bottom center of the pallet frame 1. The roller 12 and the reversing wheel 13 are installed at the bottom of the pallet frame 1. The rope of the second winch 11 passes through the reversing wheel 13 and the roller 12 and connects to the lug 10 on the positioning arm 3. The lug 10 and the side clamp 6 are located on the same side of the pin 4. The second winch 11 is connected to multiple positioning arms 3 through ropes, enabling simultaneous driving of multiple positioning arms 3 and improving work efficiency.

[0035] Before placing container 14, the second winch 11 winds up the rope and simultaneously pulls multiple positioning arms 3 to rotate to the positioning state. At this time, the connecting arm 3.2 of the positioning arm 3 is in a horizontal state and the positioning arm 3 is in contact with the limiting plate 8. During the placement of container 14, the second winch 11 is not powered. During the self-centering process of container 14 falling, the second winch 11 passively releases the rope until container 14 is self-positioned on pallet frame 1, and the side clamp 6 clamps and positions container 14.

[0036] During the process of container 14 leaving pallet frame 1, the positioning arm 3 remains in a constant state. When the height of the bottom wall of container 14 is greater than that of the side clamp 6, i.e., container 14 has completely left pallet frame 1: if the operation ends, the positioning arm 3 will remain in this state under the action of the counterweight 7 and the second winch 11 to reduce the occupied area; if the operation needs to continue, the second winch 11 will perform a rope winding action to pull the positioning arm 3 to the positioning state, i.e., the horizontal state, so that the next container 14 can achieve self-positioning.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
