Description

Technical Field

[0001] This utility model belongs to the technical field of pallet lifting tools, specifically relating to a special lifting tool for wooden pallet bases. Background Technology

[0002] In the logistics warehousing and packaging industries, wooden pallets serve as a basic carrier, and their lifting efficiency directly impacts overall logistics and packaging costs. Currently, the industry commonly faces the following technical challenges:

[0003] 1. Direct binding with ropes / chains: This requires manual wrapping around the longitudinal beams of the pallet for fixation, which presents two major problems:

[0004] 1) Concentrated stress causes local compression deformation of the longitudinal beam.

[0005] 2) Repeated friction causes burrs on the edges, shortening the lifespan of the pallet by about 30%.

[0006] II. General lifting hook operation: It needs to be used in conjunction with the pallet opening lifting lug, but more than 80% of wooden pallets do not have pre-installed lifting lug. Utility Model Content

[0007] In view of the above-mentioned shortcomings of the existing technology, this utility model provides a special lifting tool for wooden pallet bases, which aims to solve the problems of inconvenience, poor applicability and easy damage to wooden pallets by the existing lifting tools.

[0008] This utility model solves the above-mentioned technical problems through the following technical means:

[0009] A special lifting device for wooden pallet bases includes a rectangular support frame. A limiting groove is formed on the inner side of the support frame, and sliders are slidably connected to both ends of the limiting groove. A support plate is fixedly connected to the upper center of the support frame. Extension plates, slidably connected to the support frame, are provided on both sides of the support plate. Each extension plate is fixedly connected to a corresponding slider. A bidirectional threaded rod, rotatably connected to the support frame, is provided below the support plate. The two threaded sections of the bidirectional threaded rod are threadedly connected to corresponding sliders. A drive sleeve is fixedly connected to the middle of the bidirectional threaded rod. Flat strip baffles are fixedly connected to both ends of the lower side of the support frame.

[0010] Furthermore, each of the extension plates has an arc-shaped protrusion at the end away from the support plate.

[0011] This structural design allows the wooden pallet to be positioned using the arc-shaped protrusions for subsequent lifting; it also prevents the lifting straps from directly rubbing against the pallet edges during lifting, thus extending the service life of the pallet and lifting straps.

[0012] Furthermore, the surface of the drive sleeve is provided with protective texture.

[0013] This structural design makes it easier to rotate the drive sleeve.

[0014] Furthermore, the support plate has scale markings on its outer side, and the support frame has an indicator arrow at its end.

[0015] This structural design allows for precise adjustment of the extension plate's length via scale markings and indicator arrows, making it more versatile and suitable for wooden pallets of different lengths.

[0016] Beneficial effects:

[0017] 1. High applicability: The relative position of the two extensions can be flexibly adjusted according to the size of the wooden pallet to be lifted, so as to support wooden pallets of different sizes.

[0018] 2. Distribute stress and prevent deformation: The support plates and extension plates are used for support in a surface contact manner, so that the stress is borne entirely by the support plates and extension plates, reducing the risk of deformation and cracking of the longitudinal beams of the wooden pallet.

[0019] 3. Protect pallet edges: Arc-shaped protrusions are provided at the clamping points to prevent the lifting straps from directly rubbing against the pallet edges during lifting, thus extending the service life of the pallet and lifting straps.

[0020] 4. Quick positioning and locking: The slings are directly fixed in position by passing through the flat strap baffle, which enables quick and stable clamping of the pallet, reduces manual adjustment time and improves work efficiency. Attached Figure Description

Those skilled in the art can understand the advantages and effects of this utility model from the content disclosed in this specification. It should be noted that the illustrations provided in the following embodiments are for illustrative purposes only and represent schematic diagrams, not actual pictures. They should not be construed as limiting the utility model. To better illustrate the embodiments of this utility model, some components in the figures may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable that some well-known structures and their descriptions may be omitted in the figures for those skilled in the art.

[0026] In the figures of this utility model embodiment, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper", "lower", "left", "right", "front", "rear", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the figure, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe the positional relationship in the figure are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above-mentioned terms can be understood according to the specific circumstances.

[0027] like Figures 1-3 As shown, this utility model discloses a special lifting device for wooden pallet bases, including a rectangular support frame 1. A limiting groove is opened on the inner side of the support frame 1, and sliders 3 are slidably connected to both ends of the limiting groove. A support plate 4 is fixedly connected to the upper middle part of the support frame 1. Extension plates 5 are provided on both the left and right sides of the support plate 4 and are slidably connected to the support frame 1. The two extension plates 5 are respectively fixedly connected to the corresponding sliders 3. A bidirectional threaded rod 6 is provided below the support plate 4 and is rotatably connected to the support frame 1. The two threaded sections of the bidirectional threaded rod 6 are respectively threadedly connected to the corresponding sliders 3. A drive sleeve 7 is fixedly connected to the middle part of the bidirectional threaded rod 6. Flat strip baffles 8 are fixedly connected to both ends of the lower side of the support frame 1.

[0028] As a preferred embodiment, the end of the extension plate 5 away from the support plate 4 is fixedly connected with an arc-shaped protrusion 2.

[0029] As a preferred embodiment, the surface of the drive sleeve 7 is provided with protective texture.

[0030] In this embodiment, the outer side of the support plate 4 is provided with scale marking lines, and the end of the support frame 1 is provided with an indicator arrow.

[0031] When using this lifting device to lift wooden pallets, first adjust the position of the extension plate 5 according to the size of the pallet to be lifted. Rotate the drive sleeve 7, which drives the bidirectional threaded rod 6 to rotate synchronously, thereby causing the two extension plates 5 to move closer or further apart until the bearing surfaces of the two extension plates 5 mate with the wooden pallet. At this point, the arc-shaped protrusion 2 at the end of the extension plate 5 can just limit the position of the wooden pallet. After the extension plates 5 are adjusted, the lifting strap is directly fixed in position by passing it through the flat strap baffle 8. Then, the wooden pallet to be lifted can be placed on this lifting device.

[0032] The above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications and substitutions should be covered within the scope of the claims of this utility model.
