Description

Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a temporary supporting device for a curved aluminum plate ceiling. Background Art

[0002] In architectural decoration projects, curved aluminum ceilings are widely used in large public spaces such as airports, theaters, and commercial complexes due to their unique shape and modern feel. However, in the actual installation process, this type of ceiling construction faces a series of technical challenges.

[0003] Traditional installation methods usually require workers to stand on a ladder, hold up the curved aluminum plate with their hands, and align it with the predetermined installation position. Then the worker needs to temporarily fix the position of the curved aluminum plate with one hand, and use the other hand to operate the support device to extend it and support the bottom of the curved aluminum plate to achieve temporary fixation. Finally, the curved aluminum plate is firmly installed with bolts. Due to the weight of the curved aluminum plate itself and the limitations of the high-altitude working space, it is difficult for workers to quickly and accurately align the curved aluminum plate with the preset position, and multiple adjustments are often required. Especially in the process of controlling the extension of the support device, it is difficult for workers to keep the curved aluminum plate stable with one hand, causing the curved aluminum plate to slip or overturn easily, forcing workers to repeatedly correct the position of the curved aluminum plate. This situation not only prolongs the installation time of each plate, but also increases the risk of falling. In addition, for large-scale curved ceiling projects, the use of manual repeated lifting will not only greatly consume the workers' physical strength, but also reduce the overall installation efficiency. Summary of the invention

[0004] In view of this, the present invention provides a temporary support device for a curved aluminum plate ceiling, which overcomes the shortcomings that when workers manually lift the curved aluminum plate for installation, it is difficult to quickly and accurately align the curved aluminum plate to a preset position, multiple adjustments are required, which is time-consuming and labor-intensive, and the installation efficiency is low. In addition, when operating the support device, it is difficult to keep the curved aluminum plate stable with one hand, which increases the risk of falling.

[0008] Further, the pulling component includes: a winch installed on the rotating column, and the steel wire rope of the winch is connected to the rotating shell; a counterweight block connected to the end of the rotating shell.

[0009] Further, the moving component includes: mounting plates symmetrically connected to the bottom of the support frame; rolling balls rotatably connected to the bottom of the mounting plates.

[0010] Further, it further includes a reset component, and the reset component includes: fixing plates respectively and symmetrically connected to the connecting seat and the guide rails; guide rods connected to the fixing plates; moving plates respectively connected to the first sliding seat and the second sliding seat, and the moving plates are slidably connected to the guide rods; a reset spring wound around the outside of the guide rods, and both ends of the reset spring are respectively connected to the moving plate and one of the fixing plates.

[0012] Furthermore, it further includes: a fourth electric push rod, symmetrically installed on the top of the mounting plate; a friction plate, connected to the telescopic rod of the fourth electric push rod, and the rolling ball penetrates through the friction plate.

[0032] As Figure 1 shown in the figure, the pulling assembly includes a winch 21 and a counterweight 2101. The winch 21 is installed in the middle of the left side of the rotating column 3. There are two steel wires on the winch 21, and both of the two steel wires on the winch 21 are connected to the right side of the bottom of the rotating shell 4.

[0033] As Figure 7 shown in the figure, the moving assembly includes a mounting plate 22 and a rolling ball 2201. Four mounting plates 22 are symmetrically connected to the bottom of the support frame 1, and rolling balls 2201 are rotatably connected to the bottoms of the four mounting plates 22.

[0034] As Figure 8 and Figure 9 shown in the figure, it further includes a reset assembly. The reset assembly includes a fixing plate 23, a guide rod 24, a moving plate 25 and a reset spring 26. The fixing plates 23 are symmetrically connected before and after between the two guide rails 8, and the fixing plates 23 are symmetrically connected above and below the left side of the connecting seat 6. The number of the fixing plates 23 is four and they are grouped in pairs. A guide rod 24 is connected between the middles of the two fixing plates 23 in the same group. The moving plates 25 are connected to the middles of the first sliding seat 7 and the second sliding seat 9 respectively.

Reset springs 26 are wound around the outer sides of the two guide rods 24, and the two ends of the reset springs 26 are respectively connected to the moving plate 25 and one of the fixing plates 23.

[0035] As Figure 10 and Figure 11 shown in the figure, it further includes a fixing ring 27, a third electric push rod 28, a sliding cylinder 29 and a friction pad 30. The fixing ring 27 is connected to the upper part of the support frame 1. Two third electric push rods 28 are symmetrically installed at the lower part of the rotating column 3. A sliding cylinder 29 is connected between the telescopic rods of the two third electric push rods 28. The sliding cylinder 29 is sleeved on the outer side of the rotating column 3. The friction pad 30 is connected to the bottom of the sliding cylinder 29, and the friction pad 30 is located directly above the fixing ring 27.

[0036] As Figure 12 shown in the figure, it further includes a fourth electric push rod 31 and a friction plate 32. Two fourth electric push rods 31 are installed on the top of each of the four mounting plates 22. A friction plate 32 is connected between the telescopic rods of the two fourth electric push rods 31. The top of the friction plate 32 contacts the bottom of the mounting plate 22, and the rolling ball 2201 penetrates through the friction plate 32.

[0037] When the installation of the arc-shaped aluminum plate is required, first place the arc-shaped aluminum plate on the left side of the arc-shaped sealing ring 11 and make it contact with the arc-shaped sealing ring 11. Then, control the vacuum pump 10 to start working through the controller 2, so that the vacuum pump 10 can adsorb and fix the arc-shaped aluminum plate on the left side of the arc-shaped sealing ring 11. At this time, the weight of the arc-shaped aluminum plate will be concentrated at the left end of the rotating shell 4. Through the cooperation of the hoist 21 and the counterweight 2101, the weight of the arc-shaped aluminum plate can be overcome to keep the rotating shell 4 stable. Then, the controller 2 can be used to control the hoist 21 to start working. The hoist 21 will wind up the steel wire rope on it, so as to pull the right end of the rotating shell 4 to rotate downward, making the rotating shell 4 rotate to a vertical state, so that the rotating shell 4 and the counterweight 2101 are both sleeved outside the counterweight 2101, and the rotating shell 4 can drive the arc-shaped aluminum plate to rotate upward to a horizontal state. Then, under the action of the rolling ball 2201, the support frame 1 can be pushed to move below the pre-installation position. The steering flexibility of the rolling ball 2201 is better than that of the traditional universal wheel, which can avoid the jamming problem of the universal wheel. Then, the controller 2 can be used to control the fourth electric push rod 31 to drive the friction plate 32 to move downward to contact the ground. Through the friction force between the friction plate 32 and the ground, the support frame 1 can be locked to prevent the device from moving. Then, the controller 2 can be used to control the first electric push rod 5 to drive the connecting seat 6, the first sliding seat 7, the guide rail 8, the second sliding seat 9 and the vacuum pump 10 to move upward, driving the arc-shaped aluminum plate to move upward close to the pre-installation position. At this time, the worker can move to a high altitude with the help of a ladder. Then, by rotating the rotating column 3, the arc-shaped aluminum plate can be driven to rotate to adjust the angle of the arc-shaped aluminum plate, or the arc-shaped aluminum plate can be moved forward, backward, left and right to adjust the horizontal position of the arc-shaped aluminum plate. At this time, the first sliding seat 7 and the second sliding seat 9 will respectively move adaptively on the connecting seat 6 and the guide rail 8, driving the moving plate 25 to move along the guide rod 24, and the return spring 26 will deform adaptively. When the arc-shaped aluminum plate is aligned with the pre-installation position, the worker can say "lock". When the voice control module 14 receives this keyword, it will send a signal. After receiving the signal, the controller 2 will control the second electric push rod 19 and the third electric push rod 28 to start working. The second electric push rod 19 will drive the two round plates 17 in the same group to move away from each other. The round plate 17 will drive the two inserting rods 16 in the same group to move away from each other, so that the inserting rods 16 pass through the round holes 20 and then contact the connecting seat 6 and the guide rail 8 respectively. Through the friction force between the inserting rods 16 and the connecting seat 6 and the guide rail 8, the first sliding seat 7 and the second sliding seat 9 can be locked to prevent the first sliding seat 7 and the second sliding seat 9 from continuing to move. At the same time, the third electric push rod 28 will drive the sliding cylinder 29 and the friction pad 30 to move downward, so that the bottom of the friction pad 30 contacts the top of the fixed ring 27. Through the friction force between the friction pad 30 and the fixed ring 27, the rotating column 3 can be locked to prevent the rotating column 3 from rotating freely.Then, the controller 2 controls the first electric push rod 5 to drive the connecting seat 6, the first sliding seat 7, the guide rail 8, the second sliding seat 9 and the vacuum pump 10 to continue moving upward, which can drive the arc-shaped aluminum plate upward to be accurately aligned with the pre-installed position. Then, the arc-shaped aluminum plate can be fixedly installed in place manually. Then, the controller 2 controls the vacuum pump 10 to stop working, so that the vacuum pump 10 no longer sucks the arc-shaped aluminum plate. Then, the controller 2 controls the first electric push rod 5 to drive the connecting seat 6, the first sliding seat 7, the guide rail 8, the second sliding seat 9 and the vacuum pump 10 to move downward to reset. Then, the worker can say "unlock". When the voice control module 14 receives this keyword, it will send a signal. After receiving the signal, the controller 2 will control the second electric push rod 19, the third electric push rod 28 and the fourth electric push rod 31 to work again. The second electric push rod 19 will drive the two circular plates 17 in the same group to move toward each other to reset. The circular plates 17 will drive the two inserting rods 16 in the same group to move toward each other, so that the inserting rods 16 are separated from their corresponding circular holes 20, unlocking the first sliding seat 7 and the second sliding seat 9. At this time, the reset spring 26 will return to its original state, driving the moving plate 25, the first sliding seat 7 and the second sliding seat 9 to move back to the middle positions of the connecting seat 6 and the guide rail 8 respectively. At the same time, the third electric push rod 28 will drive the sliding cylinder 29 and the friction pad 30 to move upward to reset, so that the friction pad 30 is separated from the fixed ring 27, unlocking the rotating column 3. At the same time, the fourth electric push rod 31 will drive the friction plate 32 to move upward to reset, so that the friction plate 32 is separated from the ground, unlocking the support frame 1. Finally, the controller 2 controls the winch 21 to loosen the steel wire rope thereon, so that the rotating shell 4 can be reversed to the horizontal state. By repeating the above operations, the arc-shaped aluminum plate can be installed again. For arc-shaped aluminum plates with different curvatures, the fastening bolts 13 can be loosened, and then the arc-shaped sealing rings 11 that are adapted can be replaced.
