Description

A steel structure lifting device

Technical Field

The utility model relates to the technical field of hoisting devices, in particular to a steel structure hoisting device.

Background Art

Steel structure is a structure made of steel materials. It is one of the main types of building structures. Its structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. At the same time, rust removal and rust prevention processes such as silanization, pure manganese phosphating, water washing and drying, and galvanizing are used. Welds, bolts or rivets are usually used to connect the components or parts. Steel structure is widely used in large factories, stadiums and other buildings because of its light weight and simple construction. During the construction and installation of steel structure, it needs to be hoisted, but the existing hoisting device is not convenient for adjusting the hook position. The hoisting device needs to be moved to the side of the steel structure for hoisting, which is very troublesome.

For example, a Chinese utility model patent disclosed in the Chinese patent publication with the publication number CN219469490U and the authorization announcement date of August 4, 2023 discloses a steel structure lifting device, including a lifting device and a stabilizing mechanism, wherein the stabilizing mechanism is arranged on the surface of the lifting device; the lifting device includes a lifting frame, a telescopic unit, a lifting plate and a clamp; the stabilizing mechanism includes a connecting plate fixedly connected to the surfaces of both sides of the lifting frame, the number of the connecting plates is six and they are evenly distributed at the front and rear ends and the outer sides of both sides of the lifting frame, and the top of the connecting plate and the surface of the lifting frame are fixedly connected with hinges,

However, in actual use, although the design of the stabilizing mechanism of the above device makes the steel structure more stable when being hoisted and does not tip over or distort, the hoisting device is not convenient for adjusting the position of the hook, and the hoisting device needs to be moved to the side of the steel structure for hoisting. In this case, the hoisting device needs to be moved frequently in actual use, which is very troublesome.

In this embodiment, when the position of the hook 9 needs to be adjusted, the first motor 4 on the support frame 3 is first turned on, and the second gear 5 will rotate under the drive of the first motor 4. Since the second gear 5 is meshed and connected with the first gear 2 on the base 1, and the support frame 3 and the first gear 2 are rotatably connected together, when the second gear 5 rotates, the support frame 3 will rotate, and the direction of the hook 9 will change accordingly. When the direction of the hook 9 is located in the direction of steel structure hoisting, the first motor 4 is turned off, and then the first hydraulic rod 7 is turned on. Under the drive of the first hydraulic rod 7, the slide bar 6 will move, thereby driving the hook 9 to move, so as to adjust the distance between the hook 9 and the support frame 3, and the second hydraulic rod 8 is opened while the first hydraulic rod 7 is opened to support the slide bar 6.

As shown in Figures 1 and 3, one end of the sliding rod 6 is fixedly connected to a connecting frame 10 away from the supporting frame 3, and a winding roller 11 is provided at one end of the connecting frame 10. A lifting rope 12 is provided on the surface of the winding roller 11, and one end of the lifting rope 12 is fixedly connected to the hook 9. In this embodiment, the distance between the lifting hook 9 and the ground is adjusted by the design of the winding roller 11 and the lifting rope 12, wherein the lifting rope 12 is wound or released by the rotation of the winding roller 11, and the lifting hook 9 will move upward when the lifting rope 12 is wound, and the lifting hook 9 will move downward when the lifting rope 12 is released.

As shown in FIGS. 1 and 3 , the connecting frame 10 is rotationally connected to the winding roller 11 . In the present embodiment, the winding roller 11 can control the winding and releasing of the suspension rope 12 only when the winding roller 11 is rotationally connected to the connecting frame 10 .

As shown in FIGS. 1 and 3 , a second motor 13 is fixedly connected to one end of the connecting frame 10 , and an output end of the second motor 13 is fixedly connected to the winding roller 11 . In this embodiment, the second motor 13 is designed to provide driving force for the rotation of the winding roller 11 .

As shown in FIG. 1 , counterweights 14 are fixedly connected to the top of the base 1 at both ends of the first gear 2. In this embodiment, the counterweights 14 are designed to improve the stability of the device and avoid tipping during the lifting process.

As shown in FIG. 1 , four rollers 15 are installed at the bottom of the base 1 . In this embodiment, the design of the rollers 15 facilitates the movement of the device.

Working principle: When in use, first turn on the first motor 4 on the support frame 3, and the second gear 5 will rotate under the drive of the first motor 4. Since the second gear 5 is meshed and connected with the first gear 2 on the base 1, and the support frame 3 and the first gear 2 are rotatably connected together, when the second gear 5 rotates, the support frame 3 will rotate, and the direction of the hook 9 will change accordingly. When the direction of the hook 9 is in the direction of steel structure hoisting, the first motor 4 will be turned off, and then the first hydraulic rod 7 will be turned on. Under the drive of the first hydraulic rod 7, the slide bar 6 will move, thereby driving the hook 9 to move. When the first hydraulic rod 7 is turned on, the second hydraulic rod 8 will be opened to support the slide bar 6. When the hook 9 moves to the top of the steel structure, The first hydraulic rod 7 and the second hydraulic rod 8 are closed, and the second motor 13 is turned on. Driven by the second motor 13, the winding roller 11 will rotate, and the rope 12 wound on the winding roller 11 will be released, so that the position of the hook 9 will move downward, so that people can fix the steel structure on the hook 9, and the steel structure can be moved to the target position. At this time, the second motor 13 is turned on again to drive the winding roller 11 to rotate, so that the rope 12 is rewound on the winding roller 11, and the hook 9 will lift the steel structure. Then the first motor 4 is turned on again to adjust the direction of the hook 9, and the first hydraulic rod 7 and the second hydraulic rod 8 are opened to adjust the distance between the hook 9 and the support frame 3, so as to move the steel structure to the target position.

Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
