Technical Field

[0001] This utility model relates to the field of hoisting and transportation equipment technology, and in particular to a hoisting device for steel structure profiles. Background Technology

[0002] In construction, hoisting equipment is often used to move steel structural profiles such as H-beams and L-beams. Existing technologies, such as the hoisting devices disclosed in patent documents CN221680658U and CN217264430U, typically include a main frame with a top beam for suspending the profiles and two long, V-shaped outriggers extending forward from the bottom to provide stable support and ensure a stable center of gravity during operation. Wheels are installed under the main frame and outriggers for easy short-distance movement on the construction site.

[0003] However, while outriggers can increase the stability of the hoisting device, they also make the overall footprint of the device larger, causing inconvenience in scenarios such as warehouse storage and transporting the hoisting device to the construction site by transport vehicles.

[0037] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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 element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0039] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0040] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0041] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0042] refer to Figures 1 to 7 This utility model discloses a steel structure profile hoisting device, including a base 1, a lifting beam 2, a diagonal brace 3, a hanging mechanism 4, and an extension leg 5. The base 1 is provided with a plurality of first moving wheels 11 and a column 12. One end of the lifting beam 2 is hinged to the top of the column 12. The two ends of the diagonal brace 3 are respectively hinged to the column 12 and the lifting beam 2, so that the diagonal brace 3, the column 12, and the lifting beam 2 form a triangular support structure. The hanging mechanism 4 includes a hook 41 suspended on the lifting beam 2. The first end of the extension leg 5 is installed on the base 1, and its second end extends laterally and is equipped with a second moving wheel 51. The extension leg 5 is a foldable structure.

[0043] The multiple first moving wheels 11 distributed on the base 1 enable the base 1 to be placed stably, allowing the column 12 to stand stably. The hook 41 on the lifting beam 2 can be raised and lowered. When it is necessary to hang materials (such as steel structural profiles), the hook 41 can be lowered and the materials can be hung on the hook 41. Then the hook 41 can be raised to lift the materials off the ground. At this time, the lifting device can be pushed to transport the materials. During this process, the extended outriggers 5 can increase the support stability and prevent the material from tipping over after loading.

[0044] When not in a working state, such as Figure 5 As shown, the diagonal brace 3 can be disassembled, the lifting beam 2 can be folded onto the column 12, and the extension leg 5 can be folded up, thereby reducing the floor area and overall volume occupied by the lifting device. This makes the lifting device more compact and space-saving when stored in the warehouse. Furthermore, when using transport vehicles for bulk transfer, the loading quantity of a single transport can be significantly increased, and the number of transfer trips can be reduced, thereby effectively reducing logistics costs.

[0045] As the hanging beam 2 is brought together onto the column 12, the center of gravity shifts to the area close to the column 12. Even if the extended support leg 5 is folded up, the column 12 can still be kept stable and upright by relying solely on the multiple first moving wheels 11 on the base 1 for support.

[0046] In some embodiments, such as Figure 1 and Figure 6 As shown, the extended support leg 5 includes a first support leg segment 52 and a second support leg segment 53; the first end of the first support leg segment 52 is mounted on the base 1, and the second end of the first support leg segment 52 is hinged to the first end of the second support leg segment 53 around a vertical axis; the second movable wheel 51 is disposed at the second end of the second support leg segment 53; the second end of the first support leg segment 52 is provided with a first connecting plate 521, and the first end of the second support leg segment 53 is provided with a second connecting plate 531; the first connecting plate 521 and the second connecting plate 531 are connected by a bolt assembly (not shown) to achieve coaxial fixation of the first support leg segment 52 and the second support leg segment 53.

[0047] When the first leg segment 52 and the second leg segment 53 are coaxially arranged, the first connecting plate 521 and the second connecting plate 531 abut against each other. Both the first connecting plate 521 and the second connecting plate 531 are provided with holes (not marked in the figure) for the bolt assembly to pass through. After the first connecting plate 521 and the second connecting plate 531 are fixed by the bolt assembly, the extension leg 5 is stably kept in a straight position. When it is necessary to fold the extension leg 5, the bolt assembly between the first connecting plate 521 and the second connecting plate 531 can be removed.

[0048] In some embodiments, such as Figure 5and Figure 7 As shown, the first leg segment 52 is provided with a third connecting plate 522, and the second leg segment 53 is provided with a fourth connecting plate 532. The third connecting plate 522 and the fourth connecting plate 532 are connected by a bolt assembly (not shown) to realize the folding and fixing of the first leg segment 52 and the second leg segment 53.

[0049] When the first leg segment 52 and the second leg segment 53 are folded, the third connecting plate 522 and the fourth connecting plate 532 face each other. Both the third connecting plate 522 and the fourth connecting plate 532 have holes (not marked in the figure) for bolt assemblies to pass through. By fixing the third connecting plate 522 and the fourth connecting plate 532 with bolt assemblies, the extended leg 5 can be stably kept in its folded state, preventing it from swinging freely. This ensures that even after the lifting device is folded, it can still be moved stably without being affected by the extended leg 5.

[0050] In some embodiments, such as Figure 2 and Figure 4 As shown, the suspension mechanism 4 also includes a wire rope 42, a rope winding shaft 44, a drive assembly 45, and a pulley assembly 43. The pulley assembly 43 is disposed on the suspension beam 2. The wire rope 42 is wound around the pulley assembly 43 and one end of it is fixed to the rope winding shaft 44. The drive assembly 45 is used to drive the rope winding shaft 44 to rotate. The hook 41 is connected to the wire rope 42.

[0051] The wire rope 42 can be wound and released by driving the rope shaft 44 to rotate through the drive component 45, thereby controlling the height position of the hook 41.

[0052] The drive assembly 45 can be either an electric drive assembly 45 or a manual drive assembly 45.

[0053] like Figure 4 As shown, a manual drive assembly 45 is illustrated, which includes a worm gear 451, a worm 452, and a hand crank 453. The worm gear 451 is coaxially fixed with the rope winding shaft 44, the worm 452 is driven by the worm gear 451, the hand crank 453 is connected to the worm 452, and the worm 452 is rotatably mounted on the column 12.

[0054] When the hand crank 453 is cranked, the worm gear 452 drives the worm wheel 451 and the rope shaft 44 to rotate. At the same time, because the worm wheel 451 and worm gear 452 have a self-locking characteristic, when the hand crank 453 is released, the load on the hook 41 cannot drive the rope shaft 44 to rotate, so that the hook 41 can be stably suspended in the air.

[0055] In some embodiments, to ensure that the first moving wheel 11 can provide stable support for the base 1, such as Figure 3 As shown, the base 1 has at least three first movable wheels 11.

[0056] In some embodiments, such as Figure 1 and Figure 3 As shown, one end of the diagonal brace 3 is hinged to the column 12 via the first pin 31, and the other end is hinged to the hanging beam 2 via the second pin 32.

[0057] The first pin 31 and the second pin 32 are both detachable structures. Only by removing the first pin 31 or the second pin 32 can the triangular support structure between the diagonal brace 3, the column 12 and the hanging beam 2 be eliminated, thereby allowing the hanging beam 2 to be closed to the column 12.

[0058] In some embodiments, the lifting beam 2 is a telescopic structure. This allows the lifting beam 2 to be more easily closed onto the column 12. The telescopic structure of the lifting beam 2 can be found in existing technology and will not be described in detail here.

[0059] In some embodiments, such as Figure 1 As shown, the extension leg 5 has two legs, which are distributed in a V-shape on the horizontal plane.

[0060] Among them, the two extended legs 5 are arranged in a V-shape when straight, which can improve the support stability and prevent the hoisting device from tilting forward or to the side.

[0061] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0062] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
