Description

Technical Field

[0001] This utility model relates to the field of interior decoration technology, specifically to a gypsum board lifting and clamping device. Background Technology

[0002] Gypsum board has a wide range of uses in interior decoration construction. Its lightweight, fireproof, soundproof, and easy-to-process properties make it an indispensable material in modern interior decoration. In ceiling construction, gypsum board can effectively cover wires, pipes, air conditioning vents and other facilities, making the ceiling present a clean and beautiful visual effect and greatly enhancing the overall aesthetics of the interior space.

[0003] Currently, the installation of gypsum board for ceiling installation mainly relies on manual labor to lift the gypsum board to the designated position. Construction workers need to stand on the lifting end of the hoist and manually attach the gypsum board to the ceiling for installation.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] Combination Figures 1-6 As shown, the present invention provides a gypsum board lifting and clamping device, comprising:

[0045] The elevator 1 has a moving end and a lifting end, wherein the moving end of the elevator 1 travels on the ground, and the lifting end of the elevator 1 is provided with a lifting platform 2.

[0046] The frame 3 is mounted on the lifting platform 2, with an installation area left between the frame 3 and the lifting platform 2;

[0047] The lifting assembly 4 is mounted on the frame 3. The lifting end of the lifting assembly 4 is provided with a base 5, which is vertically displaced under the drive of the lifting assembly 4.

[0048] The rotating component 6 is mounted on the base 5. The rotating end of the rotating component 6 is provided with an adsorption clamping component 7, which is used to adsorb and fix the gypsum board. With the cooperation of the elevator 1, the lifting component 4 and the rotating component 6, the gypsum board is lifted and clamped to the designated position.

[0049] The lifting platform 1 serves as the support and lifting foundation for the entire equipment. Its moving end travels on the ground, achieving stable movement and precise positioning through its built-in drive system. The lifting end supports the lifting platform 2 and all components installed on it. When it is necessary to lift the plasterboard, the lifting platform 1 initiates its lifting action, raising the lifting platform 2 along with the frame 3, lifting assembly 4, rotating assembly 6, and suction clamping assembly 7 to the predetermined height. During this process, the lifting platform 1 ensures the smooth ascent of the entire system, avoiding swaying and tilting. The frame 3, as the structural support, is firmly set on the lifting platform 2, and the specially reserved installation area between it and the lifting platform 2 provides ample space and stability for the installation of the lifting assembly 4 and subsequent components, ensuring the stability and reliability of the entire lifting and clamping process. The lifting assembly 4 is installed... Mounted on the frame 3, the base 5 connected to its lifting end, driven by the lifting component 4, can precisely control the vertical displacement, thereby achieving precise adjustment of the gypsum board lifting height. When the base 5 rises to the appropriate position, the rotating component 6 begins to function. It is set on the base 5 and drives the adsorption clamping component 7 to rotate through its rotating end. This design allows the adsorption clamping component 7 to flexibly adjust its angle to adapt to different installation requirements. As a key component that directly contacts the gypsum board, the adsorption clamping component 7 firmly adsorbs and fixes the gypsum board on it, ensuring that the gypsum board will not slip or shift during the lifting and rotation process. Finally, with the joint cooperation of the elevator 1, the lifting component 4, and the rotating component 6, the gypsum board is smoothly and precisely lifted and clamped to the designated position, completing the entire installation process.

[0050] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 3 As shown; the lifting component 4 includes:

[0051] An electric lifting cylinder 41 is fixedly installed on the side surface of the frame 3 near the lifting platform 2 and located within the installation area. The movable end of the electric lifting cylinder 41 passes through the frame 3 and is fixedly connected to the base 5.

[0052] The displacement sensor 42 is fixedly installed on the surface of the frame 3 away from the lifting platform 2, with its detection end aligned with the surface of the base 5. When the electric lifting cylinder 41 receives the control signal, its movable end will extend and retract according to the preset stroke, thereby driving the base 5 to achieve vertical displacement. During this process, the precise control of the electric lifting cylinder 41 ensures that the lifting height of the base 5 can accurately reach the predetermined value. The displacement sensor 42 can monitor the vertical displacement of the base 5 in real time and feed this data back to the control system. When the lifting height of the base 5 reaches the preset value, the displacement sensor 42 will immediately send a signal to the control system. The control system will then adjust the working state of the electric lifting cylinder 41 according to this signal to ensure that the base 5 can stably stay at the predetermined height.

[0053] In a preferred embodiment, this utility model can be further configured as follows: Figure 1 , Figure 3 As shown; the rotating component 6 includes:

[0054] The drive motor 61 is fixedly installed on the surface of the base 5 near the frame 3, and the output end of the drive motor 61 is connected to a reducer.

[0055] The drive pinion 62 is fixedly installed on the output end of the reducer, and it rotates axially under the drive of the drive motor 61.

[0056] A connecting shaft 63 is rotatably connected to the surface of the base 5, wherein the connecting shaft 63 can rotate axially at the center of the base 5;

[0057] The large gear 64 is fixedly installed on the outside of the connecting shaft 63 and meshes with the driving pinion 62. When the drive motor 61 starts, its output power is transmitted to the driving pinion 62 through the reducer. The driving pinion 62 begins to rotate axially under the drive of the drive motor 61. The driving pinion 62 is fixedly installed on the output end of the reducer, and its rotational movement is precise and stable. The large gear 64 is fixedly installed on the outside of the connecting shaft 63 and meshes with the driving pinion 62. This gear transmission method enables the rotational movement of the driving pinion 62 to be efficiently transmitted to the large gear 64, thereby driving the connecting shaft 63 to rotate axially at the center of the base 5. The connecting shaft 63 is rotatably connected to the surface of the base 5, and its rotational movement is smooth and stable, providing stable rotational support for the adsorption clamping component 7.

[0058] In a preferred embodiment, this utility model can be further configured as follows: Figure 5As shown; a guide sleeve 8 is installed through the center of the frame 3, and a guide rod 9 is fixedly installed at the center of the side surface of the base 5 near the frame 3. The guide rod 9 can slide vertically inside the guide sleeve 8. When the lifting component 4 drives the base 5 to move vertically, the guide rod 9 will slide vertically inside the guide sleeve 8. This sliding displacement not only restricts the movement direction of the base 5, making it only able to move in a straight line along the vertical direction, but also greatly enhances the stability of the base 5 during the lifting process, preventing installation errors caused by shaking or offset.

[0059] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 , Figure 5 As shown; the adsorption clamping component 7 includes:

[0060] The rotating plate 71 is fixedly installed at the end of the connecting shaft 63, and it can move synchronously with the rotation of the connecting shaft 63.

[0061] The suction cup 72 is fixedly installed on the side surface of the rotating plate 71 away from the base 5;

[0062] A suction pump 73 is fixedly installed on the surface of the frame 3. The suction end of the suction pump 73 is equipped with a suction pipe 74, and the other end of the suction pipe 74 is connected to the suction cup 72. When it is necessary to adsorb gypsum board, the suction pump 73 is started, and its suction end is connected to the suction cup 72 through the suction pipe 74. When the suction pump 73 is working, it will form a negative pressure inside the suction cup 72, thereby firmly adsorbing the gypsum board onto the suction cup 72.

[0063] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 , Figure 6 As shown, a placement groove 10 is provided on the surface of the rotating plate 71 away from the connecting shaft 63. The placement groove 10 is provided with an end clamping component 11 for stabilizing the gypsum board. When it is necessary to lift a gypsum board with a large surface area, the end clamping component 11 will act on the end of the gypsum board and stabilize the gypsum board on the rotating plate 71 through clamping force. This clamping method not only effectively prevents the gypsum board from being damaged due to shaking or displacement during the lifting process, but also greatly improves the installation accuracy and stability of the gypsum board.

[0064] In a preferred embodiment, this utility model can be further configured as follows: Figure 4 , Figure 6 As shown; the end clamping assembly 11 includes:

[0065] A connecting bracket 111 is disposed in a placement groove 10, wherein the shape and size of the connecting bracket 111 are adapted to the placement groove 10.

[0066] Connecting piece 112 is fixedly installed at the end of connecting frame 111, wherein there are no fewer than two connecting pieces 112 and they are symmetrically distributed from left to right along the center of connecting frame 111;

[0067] The abutment seat 113 is rotatably connected to the surface of the connecting piece 112, wherein one end of the abutment seat 113 can rotate and displace on the surface of the connecting piece 112.

[0068] The first fixed shaft 114 is fixedly installed on the surface of the connecting piece 112;

[0069] The second fixed shaft 115 is fixedly installed on the surface of the abutment seat 113;

[0070] An elastic element 116, one end of which is fitted onto the outside of the first fixed shaft 114, and the other end of which is fitted onto the outside of the second fixed shaft 115, allows the elastic force of the elastic element 116 to abut the abutment seat 113 against the end of the plasterboard. A connecting frame 111 is disposed within a placement groove 10, its shape and size matching the groove. This design ensures the stable installation of the connecting frame 111 within the groove 10, providing a stable support foundation for the entire end clamping assembly 11. Connecting pieces 112 are fixedly installed at the end of the connecting frame 111, with at least two pieces arranged symmetrically around the center of the connecting frame 111. This layout not only enhances the structural stability of the end clamping assembly 11 but also provides symmetrical support points for the rotation of the abutment seat 113. The abutment seat 113 is rotatably connected to the surface of the connecting piece 112. One end of the abutment 113 can rotate and move on the surface of the connecting piece 112. This design allows the abutment 113 to flexibly adjust its angle to accommodate the ends of gypsum boards of different shapes and sizes. The first fixed shaft 114 is fixedly installed on the surface of the connecting piece 112, while the second fixed shaft 115 is fixedly installed on the surface of the abutment 113. These two fixed shafts provide positioning points for the installation of the elastic element 116. One end of the elastic element 116 is fitted onto the outside of the first fixed shaft 114, and the other end is fitted onto the outside of the second fixed shaft 115. When the gypsum board is placed on the rotating plate 71, the elastic force of the elastic element 116 will drive the abutment 113 to abut against the end of the gypsum board, thereby achieving a stable clamping of the end of the gypsum board. This elastic clamping method can not only effectively prevent the gypsum board from shaking and shifting during the lifting process, but also avoid rigid damage to the gypsum board.

[0071] In a preferred embodiment, this utility model can be further configured as follows: Figure 4As shown, the end of the rotating plate 71 has a first through hole that communicates with the placement groove 10. The surface of the connecting frame 111 has a second through hole that matches the position of the first through hole. The rotating plate 71 is provided with bolts 12 that pass through the first and second through holes. The connecting frame 111 is connected to the placement groove 10 of the rotating plate 71 by the bolts 12. After the bolts 12 pass through the first and second through holes, the connecting frame 111 is tightly connected to the rotating plate 71 by tightening the bolts 12. This connection method is not only simple in structure and easy to operate, but also has a firm connection and high stability, which can effectively prevent the connecting frame 111 from loosening or shifting during the lifting of the gypsum board.

[0072] The specific working principle of this gypsum board lifting and clamping device is as follows:

[0073] First, the operator moves the elevator 1 to the work area and ensures that its moving end moves stably on the ground. Then, the operator places the plasterboard to be installed on the suction cup 72 and starts the suction pump 73, which is connected to the suction cup 72 through the suction pipe 74. A negative pressure is formed inside the suction cup 72, thereby adsorbing and fixing the plasterboard to the suction cup 72. For plasterboard with a large surface area, the operator can also use the end clamping component 11 for additional stabilization. Specifically, the connecting frame 111 is fixed in the placement groove 10 of the rotating plate 71 by bolts 12. The elastic element 116 on the connecting piece 112 uses its elastic force to press the abutment seat 113 against the end of the plasterboard, thereby achieving a stable clamping of the end of the plasterboard.

[0074] Start the lifting platform 1, and use its lifting end to lift the lifting platform 2 together with the frame 3, lifting component 4, rotating component 6 and suction clamping component 7 set on it to the approximate working height. Then, the operator starts the electric lifting cylinder 41 in the lifting component 4, thereby driving the base 5 to make fine adjustments in vertical displacement to ensure that the gypsum board can be accurately lifted to the specified height. At the same time, the displacement sensor 42 monitors the displacement of the base 5 in real time and feeds the data back to the control system so that the operator can make precise control.

[0075] After the base 5 is raised into place, the operator starts the rotating component 6, the drive motor 61 outputs power, and after being reduced by the reducer, it drives the drive pinion 62 to rotate axially. The drive pinion 62 meshes with the large gear 64, thereby driving the connecting shaft 63 to rotate axially at the center of the base 5. The rotation of the connecting shaft 63 synchronously drives the rotating plate 71 to rotate, thereby adjusting the angle of the adsorption clamping component 7, accurately moving the plasterboard to the ceiling installation position at a higher position in the room, and completing the installation work.
