[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 are within the scope of protection of the present invention.
[0028] Example 1
[0029] See attached document Figure 1-6 It includes: main support frame, connecting frame, two sets of clamps and drive mechanism; when lifting the container, the two sets of clamps can be driven to clamp into the transport holes on the opposite side of the container, that is, the container is fixed by the two sets of clamps, and then the crane boom is started to work. The boom drives the connecting frame, main support frame and clamps to work together, thereby realizing the transfer of the container.
[0030] The connecting frame is fixedly connected to the main support and is used to connect with the crane boom; the card holders are symmetrically arranged on the main support, and the bottom ends of the two sets of card holders are respectively connected to the opposite side handling holes of the container to fix the container; the drive mechanism is installed on the keel rod 10 and is used to drive the card holders to move.
[0031] In one embodiment of this utility model, the main support includes two keel rods 10 and two connecting rods 11. Sliding sleeves 21 are fixedly installed at both ends of the connecting rods 11, and the sliding sleeves 21 are slidably connected to the outer wall of the keel rods 10. The connecting rods 11 can move on the keel rods 10. When the connecting rods 11 are moved, the clamping plate 13 can be moved, so that the clamping plate 13 can be clamped in the transport hole.
[0032] In one embodiment of the present invention, the connecting frame includes a mounting frame 14 fixedly installed between two keel rods 10, and a boom connecting plate 15 is fixedly installed on the mounting frame 14. The boom connecting plate 15 is installed on the boom of the crane. The boom connecting plate 15 and the boom can be rotatably connected by a pin.
[0033] In one embodiment of the present invention, a set of card holders includes two card plates 13, which are movably passed through the connecting rod 11. The top ends of the two card plates 13 are jointly installed with a limiting plate 12, and the bottom ends of the card plates 13 are movably inserted into the handling hole on the container. The card plates 13 are L-shaped and the bottom ends can be inserted into the handling hole.
[0034] In one embodiment of this utility model, a reinforcing rib 131 is installed on the bottom side wall of the pallet 13, and a wheel 132 is rotatably installed on the bottom wall of the pallet 13. In order to improve the strength of the pallet 13 during the handling process, the reinforcing rib 131 is provided to strengthen the structure of the pallet 13. In addition, when the pallet 13 moves, the wheel 132 is provided at the bottom of the pallet 13. When the pallet 13 moves close to the ground, the wheel 132 provides smooth movement for the pallet 13.
[0035] In one embodiment of this utility model, a damping rod 30 is fixedly installed on the outer wall of the connecting rod 11. The end of the damping rod 30 away from the connecting rod 11 is fixedly connected to the bottom wall of the limiting plate 12. A steel spring 31 is sleeved on the outside of the damping rod 30. The two ends of the steel spring 31 are fixedly connected to the outer walls of the connecting rod 11 and the limiting plate 12, respectively. When the boom moves and drives the device to move, when the boom moves the clamping plate 13 to the ground, the damping rod 30 and the steel spring 31 can buffer the impact between the clamping plate 13 and the ground, reducing the damage to the structure of the clamping plate 13 caused by the impact.
[0036] In one embodiment of this utility model, one set of driving mechanisms includes an electric telescopic rod 20 fixedly installed on the keel rod 10, and the telescopic shaft end of the electric telescopic rod 20 is fixedly connected to the outer wall of the sliding sleeve 21; wherein, when the control plate 13 moves, the electric telescopic rod 20 can be activated. After the electric telescopic rod 20 extends / retracts, it drives the sliding sleeve 21 to move. After the sliding sleeve 21 moves, it drives the connecting rod 11 to move. After the connecting rod 11 moves, it drives the plate 13 to move, thereby realizing the adjustment of the position of the plate 13; it should also be noted that: here Four electric telescopic rods 20 are provided, which are installed on two keel rods 10 respectively (two are installed on each keel rod 10). In the encoder of the controller 23, the four electric telescopic rods 20 are encoded as four serial numbers. For example, the two electric telescopic rods 20 on the left keel rod 10 are serial numbers 1 and 2, and the two on the right keel rod 10 are serial numbers 3 and 4. When the controller 23 controls the electric telescopic rods 20 to move, it can drive the four electric telescopic rods 20 to extend and retract synchronously at the same time, ensuring that the two sets of clamping plates 13 move symmetrically and achieve stable clamping of the container.
[0037] In one embodiment of this utility model, a controller 23 is installed on the keel rod 10, and a proximity switch 22 is installed on the connecting rod 11. The electric telescopic rod 20 and the proximity switch 22 are electrically connected to the controller 23 respectively. The contact of the proximity switch 22 is located about 1 cm outside the connecting rod 11. That is, when the connecting rod 11 moves close to the side wall of the container, the side wall of the container will press against the contact of the proximity switch 22. After the contact of the proximity switch 22 is pressed, the proximity switch 22 transmits an electrical signal to the controller 23, and the controller 23 transmits an electrical signal to the electric telescopic rod 20, thereby controlling the electric telescopic rod 20 to stop. At this time, the bottom end of the card plate 13 is in the position of being inserted into the transport hole.
[0038] In this embodiment, the working principle of the device is as follows: During the hoisting operation, the crane boom moves the equipment to the top of the container through the connecting frame (installation frame 14, boom connecting plate 15), and the electric telescopic rod 20 is started. Its telescopic shaft drives the sliding sleeve 21 to move on the keel rod 10, thereby pushing the connecting rods 11 on both sides to move horizontally towards the container, so that the clamping plates 13 on both sides are gradually inserted into the handling holes on both sides of the container.
[0039] During this process, the wheels 132 at the bottom of the pallet 13 contact the ground, assisting the pallet to move smoothly; when the connecting rod 11 moves to the side wall of the container, the contacts of the proximity switch 22 are pressed by the container, triggering an electrical signal transmitted to the controller 23. The controller then instructs the electric telescopic rod 20 to stop moving, ensuring that the pallet 13 is accurately engaged in the handling hole.
[0040] At this time, the buffer structure composed of damping rod 30 and steel spring 31 can absorb the impact force when the pallet touches the ground, reduce equipment vibration. After the crane starts, the main support, pallet and container are lifted as a whole through the connecting frame. The rigid clamping replaces the traditional flexible steel cable connection, avoiding the container from swaying due to inertia during the hoisting process, and improving the safety and stability of the transfer.
[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
