Detailed Embodiments

[0032] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts belong to the scope of protection of the present invention.

[0033] The present invention provides a lifting device for a suspended ceiling and a construction method thereof, which are used to install a suspended ceiling board on a roof structure. The present invention uses a winding and unwinding assembly to retract a suspension rope so as to lift the suspended ceiling structure to a position close to the roof structure, and further precisely move the suspended ceiling board to the designed elevation by adjusting the length of a telescopic adjusting member, so as to facilitate the installation of the suspended ceiling board, improve the installation accuracy of the suspended ceiling board, and improve the construction efficiency.

[0034] The following will describe the lifting device for a suspended ceiling and the construction method thereof according to the present invention with reference to the accompanying drawings.

[0035] See Figure 1 , in this embodiment, a lifting device for a suspended ceiling, which is used to install a suspended ceiling board 10 on a roof structure, the lifting device includes: a winding and unwinding assembly 20 detachably installed under the roof structure corresponding to the installation position of the suspended ceiling board 10; a suspension rope 30 wound around the winding and unwinding assembly 20, the winding and unwinding assembly 20 can wind and unwind the suspension rope 30, the bottom end of the suspension rope 30 is installed and connected to the suspended ceiling board 10, and the suspension rope 30 is retracted by the winding and unwinding assembly 20 to lift the suspended ceiling board 10 to a position close to the roof structure; an adjusting member 60 detachably installed between the roof structure and the suspended ceiling board 10, which can be telescopically adjusted, and the length of the adjusting member 60 is adjusted telescopically to move the suspended ceiling board 10 to the designed elevation for installing and fixing the suspended ceiling board 10.

[0036] In this embodiment, the lifting device can be installed on the structural beam of the roof structure, and the roof structure is installed with keels. Construction workers can stand on the keel layer or catwalk for installation construction. When installing the suspended ceiling board 10, the winding and unwinding assembly 20 is used to lift the suspended ceiling board 10 to be in contact with the adjusting member 60, the adjusting member 60 is installed and connected to the suspended ceiling board 10, and then the height of the suspended ceiling board 10 is further precisely adjusted by the adjusting member 60, so as to ensure the accuracy of the installation of the suspended ceiling board 10, the installation is more convenient, and the problem of large height error in manually controlling and adjusting the suspended ceiling board 10 is avoided.

[0037] See Figure 1, preferably, there are several adjusting members 60 which are evenly distributed on the ceiling board 10 along the edge of the ceiling board 10. The adjusting member 60 is an electric push rod. For the ceiling with an irregular curved shape, the ceiling board 10 is usually arranged in an inclined shape. It is very difficult to accurately adjust the attitude of the ceiling board 10 by manual measurement and observation, and it is very inconvenient and prone to errors. In this application, several electric push rods are evenly distributed on the ceiling board 10 along the edge of the ceiling board 10. The telescopic length of each electric push rod can be adjusted according to the attitude of the ceiling board 10, so as to realize the precise control and adjustment of the attitude of the ceiling board 10, which is more flexible and convenient and improves the construction efficiency. In the prior art, due to the limitation of the manual operation range and the difficulty in adjusting the relatively large ceiling board 10, it is usually impossible to install a relatively large ceiling board 10, resulting in a large amount of installation construction. However, the lifting device of this application can lift a relatively large ceiling board 10, such as a large ceiling board 10 of 10m * 10m. The attitude of the large ceiling board 10 can be easily adjusted by using the electric push rod, which improves the construction efficiency and has a wider application range.
