Description

Technical Field

[0001] The utility model mainly relates to the technical field of prefabricated component hoisting, in particular to an adjustable hoisting device for assembled building prefabricated components. Background Art

[0002] Prefabricated buildings are widely used in the construction industry due to their convenient transportation and simple assembly. The prefabricated components of prefabricated buildings are pre-processed in the factory and then transported to the construction and assembly site. They are assembled and installed using lifting devices in accordance with certain operating procedures.

[0003] In a hoisting device for prefabricated parts of assembled buildings (publication number CN213976702U), a horizontal frame and a rotating mechanism are included. Both ends of the horizontal frame are fixedly connected to a vertical frame. The bottom of the vertical frame is fixedly connected to a rotating shaft, and the outer side is slidably connected to a hoisting box; the rotating mechanism includes a rotating shaft, a first gear, a first motor, and a second gear. When the above-mentioned prior art is used, when it is necessary to hoist the prefabricated components, the prefabricated components can be conveniently hoisted and transported mainly through the cooperation of the wire rope and the hook. Only hoisting by the hook has a poor limiting effect on the prefabricated components, and it is inconvenient to clamp the prefabricated components. That is, during the hoisting process, the prefabricated components may fall off and other accidents may occur. On the one hand, it may injure the staff, and on the other hand, it may cause damage to the prefabricated components, which will affect its later use effect. Therefore, corresponding improvements are needed.

[0004] In a lifting device for prefabricated components of an assembled building (publication number CN112960539A), it includes a hook, a lifting rope, a lifting fixture and a balancing unit. The balancing unit includes a horizontal plate and a leveling tube. The horizontal plate is fixedly installed below the hook through a connecting rod. Pushing member 1 and pushing member 2 are installed on the bottom surface of the horizontal plate. A rolling ball that can roll along the axial direction of the leveling tube is placed in the leveling tube. A recessed portion for accommodating the rolling ball is provided in the middle of the leveling tube. Both ends of the leveling tube are respectively connected to the corresponding lifting fixtures. Switch 1 for controlling pushing member 1 and switch 2 for controlling pushing member 2 are installed inside the leveling tube. Switch 1 and switch 2 are located at both ends of the leveling tube. Pushing member 1 is located on the side where switch 2 is located, and pushing member 2 is located on the side where switch 1 is located.

[0005] When the above-mentioned prior art is in use, the prefabricated components are mainly hoisted and transported through two hoists. In actual use, when prefabricated components of different specifications need to be clamped, it is necessary to manually operate the leveling tube to rotate and adjust the distance between the two hoists to adapt to prefabricated components of different specifications. The operation is relatively cumbersome. During the clamping process of the prefabricated components, manual adjustment is required all the time, the work efficiency is low, the flexibility is poor, and the input of additional manual labor is increased. Therefore, the utility model provides an adjustable hoisting device for prefabricated parts of assembled buildings. Utility Model Content

The setting of multiple sets of protection strips can enhance the friction force of contact with the prefabricated components, and has a good anti-slip effect, which can ensure the firmness of the clamping of the prefabricated components and can be conveniently transported. In addition, the process does not require manual operation, which is simpler and more efficient. BRIEF DESCRIPTION OF THE DRAWINGS
