Description

Technical Field

[0001] This invention relates to the field of decoration technology, specifically to a lifting system for installing a large curved grid ceiling. Background Technology

[0002] Grille ceilings are widely used in large shopping malls, restaurants, bars, waiting rooms, airports, subways and other facilities. They are elegant, beautiful and durable, and are one of the commonly used ceiling materials by decoration companies. They are very popular with customers. Current technology often involves assembling the grilles first, especially large curved grilles, and then positioning and assembling the entire grille.

[0003] Chinese invention patent CN112360118A discloses a gypsum board ceiling lifting system for interior decoration, including a base. U-shaped plates are welded to the left and right sides of the top of the base, and telescopic plates are movably inserted into the U-shaped plates. A winding machine is installed on the top of the mounting plate. A ceiling lifting system is installed between the two sets of U-shaped plates. During the lifting of the gypsum board ceiling, the right end of the movable rod is driven down, leaving the anti-fall hole. At this time, the spring is in a compressed state. Simultaneously, the transmission rack slides in the groove, restricting the movement of the transmission rack. When the movable rod rises with the shell to the position of the previous set of anti-fall holes, the spring drives the movable rod to insert into the anti-fall hole. When the shell descends, the right end of the movable rod is in the anti-fall hole, and the left end is stuck in the slot, providing anti-fall protection. After lifting is completed, a rope is needed to pull the movable rod away from the anti-fall hole so that the shell can descend, maintaining stability during the lifting process.

[0004] Existing technologies are prone to collisions during the installation of gratings, which can easily cause the gratings to fall apart and be damaged. There is a need for a device that can divide a large unit of grating into multiple smaller units and transport the smaller units to assemble the larger unit, thereby reducing the load-bearing requirements of the equipment. By transferring the smaller units, the curved surface can be transformed into a smaller straight surface for direct transport, reducing the requirements for the type of hoist.

A fixing plate 207, a pressure box 209, and a horizontal box 210 are fixedly installed on the signal plate 208. The fixing plate 207 has an opening and a signal line 205 is fixedly installed on the fixing plate 207. The pressure box 209 and the horizontal box 210 are connected by a connecting pipe. A signal rod 211 is slidably installed on the pressure box 209. A return spring 212 is fixedly installed on the signal rod 211. The first end of the return spring 212 is fixedly installed on the signal rod 211, and the second end of the return spring 212 is fixedly installed on the pressure box 209.

[0034] An adjustment assembly 3 is also fixedly installed on the leveling box 201.

[0036] Leveling assembly 2 includes a leveling box 201 fixedly mounted on an adjusting spring 104. Two signal plates 208 are fixedly mounted on the leveling box 201, and the two signal plates 208 are arranged in a cross-shaped overlap. A horizontal box 210 is fixedly mounted on each of the two signal plates 208. Two pressure boxes 209 are fixedly mounted on both sides of the horizontal box 210. The pressure boxes 209 are fixedly mounted to the signal plates 208 and are connected to the horizontal box 210. Two signal rods are slidably mounted on each of the two pressure boxes 209. 211. Two signal rods 211 are fixedly mounted with return springs 212. One end of the return spring 212 is fixedly mounted to the signal rod 211, and the other end is fixedly mounted to the signal plate 208. Fixing plates 207 are respectively installed below the pressure box 209. Signal lines 205 are fixedly mounted on the fixing plates 207. Electric cylinders I204 are fixedly mounted on the signal lines 205. Four electric cylinders I204 are respectively installed on the four sides of the leveling box 201. Electric cylinders I204 are fixedly mounted to the bearing block 103. A leveling wedge block 203 is fixedly installed on the extension shaft of the electric cylinder I204. The leveling wedge block 203 is movably connected to the leveling box 201. Eight bearing bars 202 are also movably connected to the leveling box 201. A torsion spring connecting block 206 is fixedly installed on each of the eight bearing bars 202. One end of the torsion spring connecting block 206 is fixedly installed on the bearing bar 202, and the other end is fixedly installed on the bearing block 103. During operation, when the device moves to an uneven surface, the device shifts, and the leveling box 210... The balancing fluid moves towards the lower side of the signal plate 208, which in turn pushes the signal rod 211 to move. The signal rod 211 then triggers the fixed plate 207 to send a signal, which in turn drives the electric cylinder I204 in this direction to start. This in turn drives the leveling block 203 in this direction to push the leveling box 201 to move upward, thereby making the device reach a horizontal state. The leveling box 201 is restricted by eight bearing bars 202 to prevent the leveling box 201 from swinging during movement and affecting the horizontal component 2a.

[0037] like Figure 6As shown, the adjustment assembly 3 includes a load-bearing platform I303 fixedly installed on the leveling box 201. A rotating platform 301 and a rotating shaft 304 are rotatably mounted on the load-bearing platform I303. Two rotating platforms 301 are provided, connected by two fixed rods 307 and rotatably mounted on the load-bearing platform I303. Two connecting rods I302 are rotatably mounted on each of the two fixed rods 307. The connecting rods I302 are X-shaped and connected by a smooth rod. Multiple connecting rods I302 are arranged in an X-shape. The device is installed in a specific configuration (the number is determined by the set height). Electric cylinders III309 are fixedly mounted on two fixed rods 307 at the bottom. The fixed end and extended end of electric cylinder III309 are respectively mounted on the two fixed rods 307. The extended end is fixedly mounted on the fixed rods 307 via signal block II310. Signal block I308 is also fixedly mounted on the fixed rod 307 above signal block II310.

The rotating shaft 304 is fixedly installed on the rotating platform 301. During operation, when the device moves to the lifting position and the horizontal adjustment is completed, the two electric cylinders II305 control the movement of the adjusting racks I306 on both sides, which in turn drives the rotating shaft 304 to rotate, which in turn drives the rotating platform 301 to rotate. The rotation adjusts the general direction of the grid. After one alignment is completed, the grid is moved upward by the electric cylinder III309. After the upward movement is completed, the grid is fixedly assembled. After the assembly is completed, the device is reset by the electric cylinder III309. When the signal block I308 contacts the signal block II310, a signal is sent to make the leveling component 2 reset as a whole. After the reset is completed, the device is moved by the moving component 1 to transport and lift the next grid.

The gears on the shaft mesh with the transmission gear rings on the deflection brackets I405, III407, and II406, respectively. Deflection connecting rods 409 are rotatably mounted on the deflection brackets I405, II406, and III407, and a deflection transfer platform 410 is hinged to the three deflection connecting rods 409. The deflection transfer platform 410 is connected to the bearing shaft 408 via a ball joint. During operation, after the device lifts the grid to the set position, the motors I402, II403, and III404 are started respectively, which in turn drive the deflection brackets I405, III407, and II406 to rotate, thereby causing the deflection transfer platform 410 to deflect, thus completing the vertical adjustment of the grid and facilitating the assembly of the curved grid.

[0039] like Figure 9 , Figure 10 and Figure 11As shown, the clamping assembly 5 includes a connecting plate 501 fixedly mounted on the offset transfer table 410. A connecting plate I 506 is fixedly mounted on the connecting plate 501, and a connecting plate II 511 is fixedly mounted on the connecting plate I 506. Two sliding guide rods 508 and a motor IV 510 are fixedly mounted on the connecting plate II 511. The two sliding guide rods 508 are fixed by two connecting cross plates. A double-ended screw 509 is also rotatably mounted on the connecting plate II 511. The threads on both sides of the double-ended screw 509 turn in opposite directions. A drive wheel is fixedly mounted on the head screw 509. The drive wheel is connected to the drive wheel on the output shaft of the motor IV510 via a drive belt. Two locking slots 502 are slidably mounted on the sliding rod 508. The two locking slots 502 are threadedly connected to the threaded portions on both sides of the double-headed screw 509. Multiple rollers 503 (the number is set according to requirements) are rotatably mounted on each of the two locking slots 502. Two lifting plates 504 are slidably mounted on each of the two locking slots 502. The lifting plates 504 are slidably mounted via two protrusions. A spring I505 is fixedly installed on the protrusion of the lifting plate 504 on the snap-fit ​​groove 502. One end of the spring I505 is fixedly installed on the lifting plate 504, and the other end is fixedly installed on the snap-fit ​​groove 502. Two sliding strips 507 are also slidably installed on the connecting plate 501. The sliding strips 507 are slidably installed on the connecting cross plate on the sliding rod 508. The sliding strips 507 are provided with toothed grooves. A miniature cylinder 512 is also fixedly installed on the connecting plate II 511. An adjusting rack I is fixedly installed on the extended end of the miniature cylinder 512.

A toothed ring is provided on the connecting rod 514 near the adjusting rack II513. The adjusting rack II513 meshes with the toothed ring. The two connecting rods II515 are respectively hinged to the supports on both sides of the connecting shaft 516. The lower ends of the two connecting rods 514 are both convex blocks, and the two convex blocks are respectively engaged with the two sliding plates 507.

[0040] When the grating needs to be installed, it is placed on the roller 503 manually or by machine. The motor IV510 is started, which drives the double-headed screw 509 to rotate, which in turn moves the two snap-fit ​​grooves 502, allowing the grating to snap into the grooves of the snap-fit ​​grooves 502. When the grating is moved to the set position for installation, the micro cylinder 512 is started, which drives the adjusting rack II 513 to move, which in turn rotates the connecting rod 514, which in turn drives the connecting rod II 515, which in turn drives the connecting shaft 516 to rotate. This causes both connecting rods 514 to rotate, which in turn causes the convex blocks of the two connecting rods 514 to press against the grooves of the two sliding plates 507, which in turn causes the two sliding plates 507 to move upward, which in turn causes the two lifting plates 504 to move upward, allowing the grating to be removed for easy assembly.

[0041] When the lifting system of this invention is used to install a large curved ceiling grid, a whole grid needs to be divided into multiple units to facilitate the transportation and assembly of the curved grid. The separated grids are stacked and then placed onto the device one by one by machine or manually for transportation and assembly. After the small grid units are placed on the device, they are clamped by clamping component 5, and then transferred by moving component 1. After being transferred to the set position, the grid is leveled by leveling component 2 to prevent grid displacement. Then, the grid is aligned for the first time by adjusting component 3. After alignment, the grid is lifted by adjusting component 3. After being lifted to the set position, the grid is aligned for the second time by deflection component 4. After the second alignment, the grid is pushed out by clamping component 5. Finally, the grid is fixed or assembled manually. The installation of multiple grid units is finally combined to form a whole large grid, completing the installation of the large curved grid.
