Description

Technical Field

[0001] This utility model relates to the field of lifting tools, and in particular to a multi-bucket lifting tool and a multi-bucket lifting tool transfer system. Background Technology

[0002] The disposal site first transports waste bins to the site via transfer containers. To maximize the efficiency of transporting steel bins, the grids in the transfer containers are typically 3x4 or 3x8. For efficient waste disposal, the site uses multi-bin lifting devices to lift and transfer the steel bins. Existing multi-bin lifting devices are mainly 2-bin and 4-bin devices. 2-bin devices can fully accommodate fully loaded grids, but using them requires multiple lifts and switching of the device's direction, reducing overall lifting speed. 4-bin devices cannot lift fully loaded grids, requiring switching to 2-bin devices, which takes longer and affects lifting efficiency. Furthermore, existing electric multi-bin lifting devices use electric opening and closing claws. During claw closing, the tightening stroke is fixed and cannot be adjusted according to the diameter of the waste bin. Therefore, when the bin lid diameter is much smaller than a standard waste bin, the claws may not tighten properly, posing a risk of disengagement. When the bin lid diameter is larger than a standard waste bin, the claws may overtighten, risking damage to the waste bin. Utility Model Content

While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

Two translation mechanisms are designed to drive the clamps at both ends. The device is horizontally adjustable, with the central clamping device being fixed. The clamping devices at both ends are adjusted to accommodate the spacing of the buckets 10 on different racks and to adjust the stacking spacing by changing their distance from the central clamping device. In use, the rotating mechanism 2 drives the translation mechanism to rotate via the crossbeam 3, thereby adjusting the direction of the clamping devices at both ends of the crossbeam 3. The translation mechanism 41 adjusts the distance between the first, second, and third clamping devices. Then, the clamping devices simultaneously clamp multiple buckets 10 and stack them.

[0132] The specific working principle of the multi-bucket lifting device of this utility model is as follows: The crane lifts the entire device through the lifting ring 1, and then determines the position information of each mechanism through each limit switch. Then, according to the position of the bucket 10, the rotating mechanism 2 rotates, driving the crossbeam 3 to rotate, and determining the lifting direction of the clamping device. Then, the distance between each clamping device is adjusted by the translation mechanism to determine the lifting position. Then, the mechanical jaws are controlled by the telescopic component to clamp and lift the bucket 10. Taking the first telescopic component 512 controlling the first mechanical jaw 513 as an example, the specific example of clamping and lifting the bucket 10 by controlling the mechanical jaws through the telescopic component is explained. First, the extension and retraction of the first telescopic rod 62 is controlled so that the first mechanical jaw 513 is located above the end face of the bucket 10. Then, the push rod of the first electric push rod 71 is controlled to retract, so that the first electric push rod 71 drives the first hook to fix. The ring 73 moves upward, lifting the second end of the first hook 74, thus putting the first hook 74 into the open state (open claw). Then, by controlling the extension and retraction of the second end of the first telescopic rod 62, the positioning ring 75 is made to fit against the inner end face of the bucket 10, thus positioning the end face of the bucket 10. Then, the push rod of the first electric push rod 71 is extended, causing the first electric push rod 71 to drive the first hook fixing ring 73 downward, so that the second end of the first hook 74 falls freely under the load and fits against the side wall of the bucket 10, thus putting the first hook 74 into the open / closed state (closed claw). The crane lifts the lifting ring 1, causing the first telescopic rod 62 to drive the first locking head 72 upward, which in turn drives the first end of the first hook 74 upward, causing the first end of the first hook 74 to rotate inward around the first waist-shaped groove 741, thus achieving the hooking of the hook 742. Because the mechanical gripper tightens using the weight of the lifting device, the tightening profile is adaptive to the bucket 10, and the tightening force is related to the weight of the bucket 10, there is no problem of inadequate clamping or over-tightening. This solves the problems of hook detachment and damage to the bucket 10 during the gripping process of existing multi-bucket lifting devices, enabling rapid clamping of the bucket 10 while ensuring its integrity and preventing damage.

[0133] In a preferred embodiment of this utility model, the multi-bucket lifting device further includes:

[0134] Cameras 8 are installed on both sides of the third clamping device, and the cameras 8 are used to monitor the real-time status of the clamping device.

[0135] The multi-bucket lifting device of this utility model can grab multiple buckets 10. When grabbing, it can adapt to large contour errors of the buckets 10, and there is no risk of the claws disengaging after successful grabbing or excessive clamping force damaging the buckets 10. It can adapt to various existing grids, and when the grid is fully loaded, it can lift all the buckets 10 with the fewest lifting operations, improving the handling efficiency of the buckets 10. For example, when the grid can only lift and place two buckets 10 at a time, any two clamping devices can be controlled for lifting. When only one is needed, there is no need to replace the clamping device. The distance between the clamping devices can be adjusted directly to use one for lifting, which greatly saves the time of replacing the clamping devices and improves the handling efficiency of the buckets 10.

[0136] This utility model provides a multi-barrel lifting device transfer system, including: a control box 9, a crane, a host computer, and a multi-barrel lifting device; the multi-barrel lifting device is the multi-barrel lifting device described in the above embodiment, wherein the control box 9 is mounted on the multi-barrel lifting device, the multi-barrel lifting device is suspended on the crane by a lifting ring, and the host computer receives feedback signals from limit switches through the control box 9, thereby controlling the crane to lift the barrels 10.

[0137] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
