Description

Technical Field

[0001] This application relates to the field of lifting device technology, and in particular to a lifting device for prefabricated components. Background Technology

[0002] Currently, with the development of prefabricated buildings, the requirements for lifting devices for their steel components are becoming increasingly stringent. In the existing construction process of prefabricated buildings, hooks are mostly used to lift steel components.

[0003] Patent publication number CN222540229U discloses a lifting device for prefabricated components, including a lifting device and a bracket plate. One end of the lifting device has a limiting groove, and a limiting block is slidably connected in the limiting groove. A rotating column is welded to the inner wall of the limiting block, and a first gear is welded to the outer wall of the rotating column. A lifting plate is welded to the other end of the rotating column. A drive motor is installed on the lifting device, and a second gear is installed at the output end of the drive motor, and the second gear meshes with the first gear. The inner wall of the lifting device is bonded with a Velcro surface, and a Velcro hook surface is bonded to the Velcro surface.

[0004] However, in the aforementioned patent, the lifting plate is fixed to the rotating column, which occupies a large space when clamping steel components. It is inconvenient to clamp the steel components when they are in a narrow area. At the same time, it cannot be adapted to different components, and the human eye is required to align them when they are lowered, which is not conducive to quick positioning and installation. Utility Model Content

The lifting device extends along the Z-axis and has a first end and a second end opposite to the first end. A plurality of lifting plates are detachably connected to the second end. Each lifting plate has a positioning part, and the second end cooperates with the positioning part to position the lifting plate.

[0007] It also includes a laser positioner, which is detachably mounted on one side of the lifting device.

[0008] As a preferred embodiment of the prefabricated component lifting device in this utility model, the lifting device is provided with a detachable anti-slip plate inside.

[0009] As a preferred embodiment of the prefabricated component lifting device in this utility model, the anti-slip plate is composed of a wear-resistant base plate and a replaceable polyurethane layer connected by bolts.

[0011] As a preferred embodiment of the prefabricated component lifting device in this utility model, the laser positioner is magnetically connected to the clamp or steel component.

[0012] As a preferred embodiment of the prefabricated component lifting device in this utility model, the laser positioner is provided with a horizontal bubble.

[0013] The beneficial effects of this utility model are:

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.

[0027] It should be noted that when an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. The terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0028] Example

[0029] This embodiment provides a prefabricated component lifting device, such as... Figure 1 As shown, the device includes a lifting device 1000 and a lifting plate 2000. The lifting device 1000 extends along the Z-axis and has a first end and a second end opposite to the first end. A plurality of lifting plates 2000 are detachably connected to the second end. Each lifting plate 2000 has a positioning part, and the second end cooperates with the positioning part to position the lifting plate 2000.

[0030] The lifting device 1000 includes an outer frame and a clamp. The outer frame is provided with a mounting groove for mounting the clamp. The clamp is rotatably connected to the outer frame via a pin. The first end, i.e., one end of the clamp, is connected to the lifting rope, and the second end, i.e., one end of the outer frame, is connected to the lifting plate 2000.

[0031] In this embodiment, the chuck is provided with a detachable anti-slip plate 4000 inside. The anti-slip plate 4000 is composed of a wear-resistant base plate and a replaceable polyurethane layer connected by bolts, and is connected to the chuck by the bolts. The bolts and the detachable anti-slip plate 4000 are connected by countersunk bolt holes to prevent damage to the bolts or steel components during hoisting.

[0032] The positioning part of the lifting plate 2000 is connected to the second end by mechanical connection. It can also be connected to the bottom of the outer frame by bolts. By changing its shape, it can be adapted to different steel components, thus enhancing the applicability of the device. The lifting plate 2000 and the lifting device 1000 are set as a detachable structure, which can be used to clamp steel components in narrow environments.

[0033] When not hoisted, the laser positioner 3000 is magnetically connected to the hoisting device. When hoisted, it is magnetically connected to the steel component. During hoisting, it is attached to one side of the connection of the steel component, and the laser emitted by it corresponds to the side of the steel component to be installed, so as to locate the installation position of the steel component.

[0034] In this embodiment, the laser positioner 3000 is equipped with a horizontal bubble to ensure that the emitted laser can be accurately positioned.

[0035] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0036] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
