After the construction is completed, they are manually disassembled and transported. Since the installation and disassembly process of the above structure is too troublesome, the workload of the workers is increased. The free body is large during the later transportation, which makes it inconvenient to transport. Therefore, it is necessary to redesign a new foldable lifting scaffold to address the above problems.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A new type of foldable lifting scaffold comprises a base plate 1, a plurality of pulleys 2 are fixedly mounted on the bottom wall of the base plate 1, each pulley 2 is a universal wheel, and the convenience of movement of the base plate 1 can be increased by the universal wheel, and a plurality of connecting plates 4 are rotatably mounted on the bottom wall of the base plate 1 through a connecting mechanism, and the connecting mechanism comprises a connecting block 3 fixedly mounted on the bottom wall of the base plate 1, and the end of the connecting block 3 is rotatably connected to the upper end surface of the connecting plate 4, and the bottom wall of each connecting plate 4 is connected to a support plate 6 through a telescopic mechanism, and the telescopic mechanism comprises a cylinder 5 fixedly mounted on the bottom wall of the connecting plate 4, and the telescopic end of the cylinder 5 is fixedly connected to the upper end surface of the support plate 6, and two double-headed screws 8 are rotatably mounted on the upper end surface of the base plate 1 through a storage frame 7, and the outer walls of the two double-headed screws 8 are connected through a transmission mechanism, and the transmission mechanism comprises a pulley 9 fixedly mounted on the outer walls of the two double-headed screws 8, and the two pulleys 9 are connected and driven by belts.

[0023] A motor 10 connected to one of the double-headed screws 8 is fixedly installed on the outer wall of the storage frame 7. Two movable sleeves 12 are threadedly installed on the outer walls of the two double-headed screws 8. The two movable sleeves 12 can be moved in both directions under the drive of the double-headed screws 8, so that the two movable sleeves 12 can be moved closer to or farther away from each other. Two limit rods 11 are fixedly installed inside the storage frame 7. The limit rods 11 slide through the movable sleeves 12. The limit rods 11 can limit the movable sleeves 12 so that they can only move axially along the outer wall of the double-headed screw 8. A first connecting frame 13 is fixedly installed on the upper end surface of each movable sleeve 12. Each first connecting frame 13 The interior is rotatably connected to a second connecting frame 16 through a connecting mechanism, and the connecting mechanism includes a connecting plate 14 rotatably installed inside the first connecting frame 13, and the end of the connecting plate 14 is rotatably connected to the inside of the second connecting frame 16. A connecting rod 15 is rotatably installed between each connecting plate 14. With the series connection of the connecting rod 15, the stability of the connecting plate 14 can be increased. The outer wall of each second connecting frame 16 is commonly fixedly connected to a shelf plate 17, and an extension groove is opened on the outer wall of the shelf plate 17. An extension plate 18 is slidably installed inside the extension groove, and the ends of the two extension plates 18 are fixedly installed with limit plates 19 that cooperate with the inner wall of the extension groove.

[0024] When the utility model is used, the bottom plate 1 can be conveniently moved by means of a plurality of pulleys 2. When the shelf plate 17 needs to be used, the motor 10 drives one of the double-headed screws 8 to rotate, and one of the double-headed screws 8 drives the other double-headed screw 8 to rotate through two pulleys 9 connected by belts. The two double-headed screws 8 rotate at the same time and respectively drive the two moving sleeves 12 to approach each other through the cooperation of the limit rods 11. At the same time, under the movement of the moving sleeves 12, the connecting plate 14 can rotate inside the first connecting frame 13, and each connecting plate 14 also rotates on the outer wall of the connecting rod 15, thereby adjusting the inclination angle of the connecting plate 14, and driving the shelf plate 17 to move upward through the cooperation of the plurality of second connecting frames 16, thereby adjusting the height of the shelf plate 17.

[0025] When the shelf plate 17 is in use, the extension plate 18 can be slid out from the extension groove to increase the usable area. The limit plate 19 can limit the extension plate 18 to prevent it from detaching from the extension groove. Then, the connecting plate 4 can be rotated by the connecting block 3 to unfold it, and the cylinder 5 drives the support plate 6 to move downward so that its bottom wall contacts the ground. As a result, the bottom plate 1 can be lifted up so that the pulley 2 does not contact the ground. The cooperation of multiple connecting plates 4 and support plates 6 can increase the supporting area, thereby improving the supporting effect, avoiding tipping accidents during high-altitude operations, and increasing the safety of high-altitude operations. When the scaffolding is not in use, the motor 10 is reversed, and under the drive of the double-headed screw 8, the shelf plate 17 can move downward, and the multiple connecting plates 14 can be folded into the storage frame 7, thereby reducing the volume of the scaffolding and facilitating its placement and transportation.

[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
