Description

Technical Field

[0001] This utility model relates to the field of scaffolding cantilever technology, and more specifically, to a scaffolding cantilever device. Background Technology

[0002] In construction, scaffolding is a widely used temporary support structure that provides workers with a safe working platform and access for various high-altitude operations, such as bricklaying, plastering, and installation. However, in some special building structures or construction scenarios, conventional scaffolding erection methods may not meet the construction requirements.

[0003] Current cantilever scaffolding devices are limited by space constraints, resulting in insufficient space for workers to move around freely on the cantilever platform, affecting the smoothness of construction operations and reducing work efficiency. When painting exterior walls, workers may not be able to flexibly wield painting tools due to the confined space, leading to a decline in painting quality. Therefore, a cantilever scaffolding device is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a scaffolding cantilever device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides a scaffolding cantilever device, including an L-shaped fixing plate. A U-shaped lifting plate is provided on the inner side of the L-shaped fixing plate. Two sliding holes are provided on both sides of the U-shaped lifting plate, and the two sliding holes are positioned far apart from each other. An extension assembly is provided on the U-shaped lifting plate, and the extension assembly includes two extension plates. The two extension plates rotate within the U-shaped lifting plate and flip away from the center position. A receiving plate is slidably installed in the two corresponding sliding holes on both sides of the U-shaped lifting plate. The receiving plate is located on the bottom side of the extension plate. A connecting block is fixedly connected to both sides of the receiving plate near the middle position. A first sliding rod is fixedly connected to the middle position on one side of the connecting block. A limit block is slidably installed on the outer side of the first sliding rod and is fixedly connected to one side of the U-shaped lifting plate. A compression spring is sleeved on the outer side of the first sliding rod, and the compression spring is located between the connecting block and the limit block. One end of the compression spring is fixedly connected to one side of the connecting block, and the other end of the compression spring is fixedly connected to one side of the limit block.

[0006] As a further improvement to this technical solution, limit rods are fixedly connected to both sides of the U-shaped lifting plate. The two limit rods are set far apart from each other. A J-shaped locking strip is rotatably connected to the outer side of the limit rod. The J-shaped locking strip is used to lock the first sliding rod.

[0007] As a further improvement to this technical solution, a fixing block is fixedly connected to the middle of both sides of the U-shaped lifting plate near the top. A pressing rod is slidably installed on the upper part of the fixing block. A pressing platform is fixedly connected to the bottom end of the pressing rod. A return spring is sleeved on the outer side of the pressing rod. One end of the return spring is fixedly connected to the bottom side of the fixing block, and the other end of the return spring is fixedly connected to the top side of the pressing platform.

[0008] As a further improvement to this technical solution, two limiting strips are fixedly connected to the bottom side of the U-shaped lifting plate, and the two limiting strips are set far apart from each other. The U-shaped lifting plate is limited by the two limiting strips, and at the same time, the U-shaped lifting plate moves vertically inside the L-shaped fixed plate.

[0009] As a further improvement to this technical solution, two telescopic cylinders are provided on the bottom side of the U-shaped lifting plate, and the two telescopic cylinders are arranged far apart from each other. Both telescopic cylinders are fixedly connected to the L-shaped fixed plate, and the piston rod end of the telescopic cylinder is fixedly connected to the bottom side of the U-shaped lifting plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] In the cantilever scaffolding device, pressing two pressing rods causes the compression platform to compress two J-shaped locking strips. At the same time, the J-shaped locking strips disengage from the first sliding rod, allowing the compression spring to drive the first sliding rod to slide on the limit block via the connecting block. Simultaneously, the connecting block drives the receiving plate to move outward, and then flips the two extension plates, thereby increasing the workers' activity space and preventing insufficient activity from affecting the workers' construction efficiency.

[0019] Example 1

[0020] Please see Figures 1-3As shown, this embodiment provides a scaffolding cantilever device, including an L-shaped fixing plate 1. A U-shaped lifting plate 2 is provided on the inner side of the L-shaped fixing plate 1. Two sliding holes are provided on both sides of the U-shaped lifting plate 2, and the two sliding holes are arranged far apart from each other. An extension component 3 is provided on the U-shaped lifting plate 2. The extension component 3 can increase the workers' activity space and increase their work efficiency. The extension component 3 includes two extension plates 31, which rotate inside the U-shaped lifting plate 2 and flip away from the center position. The two extension plates 31 can increase the workers' activity space. A receiving plate 32 is slidably installed in the two corresponding sliding holes on both sides of the U-shaped lifting plate 2. The receiving plate 32 is located on the bottom side of the extension plate 31. The receiving plate 32 limits the movement of the extension plate 31 and provides support. Connecting blocks 33 are fixedly connected to both sides of the receiving plate 32 near the middle. These connecting blocks 33 allow the receiving plate 32 to move along the bottom side of the extension plate 31. Simultaneously, the U-shaped lifting plate 2 limits the movement of the receiving plate 32, preventing it from shifting during sliding. A first sliding rod 34 is fixedly connected to the middle of one side of each connecting block 33. A limiting block 35 is slidably installed on the outer side of the first sliding rod 34 and fixedly connected to one side of the U-shaped lifting plate 2. The limiting block 35 ensures the movement of the first sliding rod 31. The sliding of the first sliding rod 34 prevents it from shifting during sliding. A compression spring 36 is sleeved on the outer side of the first sliding rod 34, and the compression spring 36 is located between the connecting block 33 and the limiting block 35. One end of the compression spring 36 is fixedly connected to one side of the connecting block 33, and the other end is fixedly connected to one side of the limiting block 35. The compression spring 36 drives the first sliding rod 34 to slide on the limiting block 35. Limiting rods 37 are fixedly connected to both sides of the U-shaped lifting plate 2. The two limiting rods 37 are set far apart from each other. A J-shaped locking strip 38 is rotatably connected to the outer side of the limiting rod 37. The J-shaped locking strip 38 is used to lock the first sliding rod 34. The middle of both sides of the U-shaped lifting plate 2 is close to the top. Each position is fixedly connected to a fixing block 39. A pressing rod 311 is slidably installed on the upper part of the fixing block 39. A pressing platform 312 is fixedly connected to the bottom end of the pressing rod 311. A return spring 313 is sleeved on the outside of the pressing rod 311. One end of the return spring 313 is fixedly connected to the bottom side of the fixing block 39, and the other end of the return spring 313 is fixedly connected to the top side of the pressing platform 312. By pressing the two pressing rods 311, the pressing platform 312 presses the two J-shaped locking strips 38. At the same time, the J-shaped locking strips 38 are disengaged from the first sliding rod 34. Thus, the pressing spring 36 drives the first sliding rod 34 to slide on the limiting block 35 through the connecting block 33. At the same time, the connecting block 33 drives the receiving plate 32 to move outward.

[0021] Please see Figure 1 As shown, two limiting strips 4 are fixedly connected to the bottom side of the U-shaped lifting plate 2, and the two limiting strips 4 are set far apart from each other. The two limiting strips 4 limit the U-shaped lifting plate 2 and at the same time make the U-shaped lifting plate 2 move vertically inside the L-shaped fixed plate 1, so as to prevent the U-shaped lifting plate 2 from deviating during vertical movement. Two telescopic cylinders 5 are provided on the bottom side of the U-shaped lifting plate 2, and the two telescopic cylinders 5 are set far apart from each other. Both telescopic cylinders 5 are fixedly connected to the L-shaped fixed plate 1, and the piston rod end of the telescopic cylinder 5 is fixedly connected to the bottom side of the U-shaped lifting plate 2, so as to make height adjustment and thus increase the work efficiency of the workers.

[0022] In practical use, the scaffolding cantilever device of this embodiment firstly presses the two pressing rods 311 to cause the pressing platform 312 to press the two J-shaped locking strips 38. At the same time, the J-shaped locking strips 38 disengage from the first sliding rod 34, so that the pressing spring 36 drives the first sliding rod 34 to slide on the limiting block 35 through the connecting block 33. At the same time, the connecting block 33 drives the supporting plate 32 to move outward, and then flips the two extension plates 31. Meanwhile, the supporting plate 32 supports the extension plates 31, thereby increasing the workers' activity space and avoiding the impact of insufficient activity on the workers' construction efficiency. Then, the two telescopic cylinders 5 drive the U-shaped lifting plate 2 to move vertically, thereby enabling height adjustment.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
