Description

Technical Field

[0001] This utility model belongs to the field of building decoration technology, and relates to a lifting device, particularly a decorative ceiling panel lifting and installation device. Background Technology

[0002] In the field of building decoration and installation, decorative ceiling panels play a crucial role. Installed on the ceiling, they enhance the visual appeal and quality of interior spaces through careful design and installation. However, current installation methods for decorative ceiling panels are quite traditional. Installation requires multiple workers to climb ladders and manually lift the panels to the ceiling. Due to the weight and volume of the panels, workers not only bear a heavy physical burden but also struggle to ensure stability, posing a significant challenge to alignment. After the panels are initially attached to the ceiling, long poles are needed to support them from the ground. This traditional method, relying on multiple workers, is inconvenient for alignment, inefficient, labor-intensive, and severely impacts construction progress. Therefore, there is an urgent need for a device that can improve the installation of decorative panels. Utility Model Content

[0021] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0022] like Figure 1 As shown, this utility model provides a decorative ceiling panel lifting and installation device, including a support cylinder 1, a base 2, a lifting mechanism 3, and a bracket 4.

[0023] The support cylinder 1 is hollow and vertically positioned. The base 2 is fixed to the bottom of the support cylinder 1 and is movable. The lifting mechanism 3 includes a worm gear 31, a worm 32, and a lead screw 33. The worm gear 31 is horizontally positioned at the top of the support cylinder 1 and is rotatably connected to the top of the support cylinder 1, allowing it to rotate relative to the support cylinder 1. The worm 32 is positioned on the side of the worm gear 31, meshes with the worm gear 31, and is rotatable. The worm gear 31 and the worm 32 together form the worm gear 31-worm gear 32 mechanism, and the worm 32 can drive the worm gear 31 to rotate. The worm gear 31 has a threaded hole penetrating its upper and lower surfaces, forming a helical transmission pair with the external thread of the lead screw 33. The lead screw 33 is vertically positioned and threadedly connected to the threaded hole, with its lower end extending into the support cylinder 1. The support cylinder 1 and the lead screw 33 are connected by a limiting structure, which restricts the rotation of the lead screw 33. When the worm 32 rotates, the worm gear 31 rotates accordingly, and the lead screw 33 moves up and down under the restriction of the support cylinder 1. The bracket 4 is fixed to the top of the lead screw 33. When the lead screw 33 rises or falls, the bracket 4 also rises and falls accordingly.

[0024] Specifically, regarding lifting mechanism 3: such as Figure 2 and Figure 3 As shown, the limiting structure includes an anti-rotation groove 34 and a guide key 35. The anti-rotation groove 34 is formed on the lead screw 33 and is arranged along its axis. The guide key 35 is fixed to the inner wall of the support cylinder 1, and its end is slidably connected in the anti-rotation groove 34. The anti-rotation groove 34 can slide up and down relative to the guide key 35, and the guide key 35 restricts the rotation of the lead screw 33. When the worm gear 31 rotates, its threaded hole also rotates synchronously, and since the guide key 35 restricts the rotation of the lead screw 33, the lead screw 33 can only be driven by the worm gear 31 to make up-down linear motion.

[0025] The worm gear 31 is rotatably connected to the top of the support cylinder 1 via the bearing 311.

[0026] A horizontally arranged support plate 321 is fixed to the side of the top end of the support cylinder 1. The worm gear 32 is equipped with a mounting base 322. The mounting base 322 is fixed on the support plate 321, and the worm gear 32 is installed in the mounting base 322 and can rotate relative to the mounting base 322.

[0027] Preferably, a handwheel 323 is fixed to one end of the worm gear 32. The worm gear 32 is driven to rotate by turning the handwheel 323, which facilitates operation.

[0028] Regarding bracket 4: Bracket 4 is telescopic, allowing for size adjustment to match different sized decorative ceiling panels. Specifically, as... Figure 1 As shown, the bracket 4 includes a support plate 41, two horizontal telescopic rods 42, and two vertical telescopic rods 43. The support plate 41 is horizontally fixed to the top of the lead screw 33. The two horizontal telescopic rods 42 are fixed to the support plate 41 and can extend and retract left and right. The two vertical telescopic rods 43 are respectively fixed to the left and right ends of the two horizontal telescopic rods 42 and can extend and retract back and forth.

[0029] Regarding base 2: as follows Figure 1 As shown, the base 2 includes four sets of support components. Each support component includes a support rod 21 and casters 22. The support rod 21 is obliquely disposed on the side of the bottom end of the support cylinder 1, with its upper end fixed to the outer wall of the support cylinder 1 and its lower end located below the bottom end of the support cylinder 1. The casters 22 are mounted on the lower end of the support rod 21 and are capable of rotation and self-locking. The four sets of support components are evenly distributed around the support cylinder 1.

[0030] Preferably, the support assembly further includes a connecting rod 23. The connecting rod 23 is disposed between the support rod 21 and the support cylinder 1, with one end fixed to the inner side of the support rod 21 and the other end fixed to the outer wall of the support cylinder 1. The support rod 21, the connecting rod 23, and the support cylinder 1 form a stable triangular structure, thereby enhancing the stability of the base 2.

[0031] The working principle of this device is as follows: the hand crank 323 drives the worm 32 to rotate, the worm 32 drives the worm wheel 31 to rotate, and then drives the lead screw 33 to move through the thread of the central threaded hole of the worm wheel 31. Because the lead screw 33 is restricted from rotating by the wire key, the lead screw 33 can only make vertical up and down linear movements. The lifting and lowering of the lead screw 33 can drive the bracket 4 to move up and down, thereby realizing the lifting and lowering of the decorative top plate.

[0032] In use, first turn the handwheel 323, which, through the transmission of the worm gear 32 and worm wheel 31, moves the lead screw 33 downward to its lowest position. Then adjust the horizontal telescopic rod 42 and the vertical telescopic rod 43 to adjust the overall length and width of the bracket 4 to fit the dimensions of the decorative ceiling panel. At this point, one worker can lift the decorative ceiling panel onto the bracket 4. Then, use the casters 22 on the base 2 to push the device and the decorative ceiling panel it supports to the installation position, and then lock the casters 22 to secure the device. Then, turn the handwheel 323 in the opposite direction, which, through the transmission of the worm gear 32 and worm wheel 31, raises the lead screw 33, thereby lifting the bracket 4 and the decorative ceiling panel it supports until the decorative ceiling panel is raised and flush against the ceiling.
