DETAILED DESCRIPTION
[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.
[0028] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0029] The present invention provides a lifting device for special-shaped workpieces, such as Figure 1-6 As shown, the sling for special-shaped workpieces includes a sling 1, a sling shell 2 is fixedly connected to the top of the sling 1, and
[0030] The buffer mechanism is provided on both sides of the exterior of the hanging shell 2, and the buffer mechanism includes:
[0031] A plate body 3 is fixedly connected to one side of the top of the sling 1, and a base body 4 is fixedly connected to one side of the plate body 3. A rotating rod 5 is connected to the inside of the base body 4 through a bearing, and a rotating plate 6 is fixedly connected to the outside of the rotating rod 5. A buffer plate 7 is fixedly connected to one side of the rotating plate 6, and a spring 8 is fixedly connected to one side of the rotating plate 6. One side of the spring 8 is fixedly connected to one side of the plate body 3. The buffer mechanism is used to provide buffering effect when the wire rope changes direction.
[0032] It should be noted that after the existing sling is connected to the wire rope, if the wire rope moves greatly due to excessive rotation of external machinery or strong winds, it will cause danger on site and easily injure workers. It is not convenient to control the sling more effectively. At the same time, it is also difficult to clamp workpieces of different sizes and shapes.
[0033] In this embodiment, when lifting work is required, the staff first needs to hook the wire rope with the lifting shell 2. At this time, the buffer plates 7 on both sides will limit the wire rope, and then the staff will lift the lifting shell 2 through external equipment. The lifting shell 2 will synchronously drive the lifting column 1 to lift during the lifting process. During this process, if the equipment rotates too fast or there is a strong wind, it will cause the entire lifting column 1 to shake. If the wind blows between the two buffer plates 7, it will be difficult to be driven because the buffer plates 7 on both sides limit the wire rope. If the wire rope moves toward the buffer plates 7 on both sides, the movement of the wire rope will drive the buffer plates 7 to rotate. During the rotation process, the buffer plates 7 will synchronously drive the rotating plate 6 to rotate and the spring 8 to compress, thereby achieving the purpose of buffering the swing amplitude of the wire rope, preventing the hanging column 1 from becoming unstable due to excessive rotational inertia or strong wind, and ensuring safety during movement.
[0034] In a further preferred embodiment of the present invention, fixing mechanisms are provided on both sides of the bottom of the suspender 1, and the fixing mechanisms include:
[0035] The sliding shell 10 is located at one side of the bottom of the suspender 1 and is configured to be U-shaped.
[0036] Sliding grooves 9 are provided on both sides of the bottom of the suspender 1 , and two sliding shells 10 are respectively slidably connected to the inside of the two sliding grooves 9 , which can facilitate the sliding work of the sliding shells 10 .
[0037] A sliding plate 11 is fixedly connected to the top of the sliding shell 10 . The sliding plate 11 is located on the outer side of the suspender 1 and is in contact with the suspender 1 . The sliding plate 11 can support and connect the sliding shell 10 .
[0038] A plurality of positioning grooves 12 are provided on one side of the bottom of the suspender 1 , and a connecting plate 13 is fixedly connected to one side of the sliding shell 10 , which facilitates the fixing work of the connecting plate 13 .
[0039] The bottom of the connecting plate 13 is fixedly connected to a connecting shell 14 , and the interior of the connecting shell 14 is fixedly connected to a second spring 15 , which facilitates the deformation of the second spring 15 .
[0040] A connecting block 16 is fixedly connected to the top of the second spring 15 , and the connecting block 16 is slidably connected to the connecting shell 14 , which facilitates the fixing and movement of the connecting block 16 .
[0041] A connecting rod 17 is fixedly connected to the bottom of the connecting block 16, one end of the connecting rod 17 is fixedly connected to a connecting column 18, and a pull plate 19 is fixedly connected to the bottom of the connecting column 18, which makes it easy for staff to pull the pull plate 19.
[0042] The pull plate 19 is located on one side of the outside of the connecting shell 14. Round shells 20 are fixedly connected to both sides of the top of the sliding shell 10. Springs three 21 are fixedly connected inside the two round shells 20, which can facilitate the fixed connection of springs three 21.
[0043] The bottoms of the two springs 21 are fixedly connected to slide posts 22, the bottoms of the two slide posts 22 are fixedly connected to pressure plates 23, and a pull rod 24 is fixedly connected between the two slide posts 22, so that the pressure plates 23 can position the special-shaped workpieces.
[0044] In this embodiment, when the staff needs to fix the special-shaped workpiece, first the staff needs to pull the pull plate 19 downward. During the movement, the pull plate 19 will synchronously drive the connecting column 18, the connecting rod 17 and the connecting block 16 to move downward. Then the spring 2 15 will be compressed inside the connecting shell 14. At this time, the sliding shell 10 will slide. During the sliding process, the sliding shell 10 will synchronously drive the above structure and the connecting plate 13 to move synchronously. When it moves to the appropriate positioning groove 12 position, the staff releases the pull plate 19. Then the spring 2 15 will quickly stretch and drive the connecting block 16 and the connecting rod 17 to move, so that the connecting column 18 is inserted into the corresponding positioning groove 12, so that the special-shaped workpiece can be placed horizontally.
[0045] Then the pull rod 24 is lifted upward. During the movement, the pull rod 24 will synchronously drive the sliding column 22 and the pressure plate 23 to move upward. During the movement, the sliding column 22 will synchronously drive the spring three 21 to be compressed. When the special-shaped workpiece is placed inside the sliding shell 10, the staff will release the pull rod 24, and then the spring three 21 will quickly stretch and drive the sliding column 22, the pressure plate 23 and the pull rod 24 to press down. At this time, the pressure plate 23 and the sliding shell 10 will clamp the special-shaped workpiece, so as to flexibly fix workpieces of different sizes.
[0046] In summary, if the wire rope moves toward the buffer plates 7 on both sides, the movement of the wire rope will drive the buffer plates 7 to rotate. During the rotation process, the buffer plates 7 will synchronously drive the rotating plate 6 to rotate and the spring 8 to compress, thereby buffering the swing amplitude of the wire rope, preventing the sling 1 from becoming unstable due to excessive rotational inertia or strong wind, and ensuring safety during movement.
[0047] Compared with related technologies, it can not only achieve buffering work when the device is moving, but also can be flexibly fixed so that special-shaped workpieces of different sizes can be limited.
