[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It can be classified according to its location as external scaffolding and internal scaffolding; according to its material as wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] In existing technologies, such as the "A Ring-Shaped Wall-Mounted Scaffold" (Chinese Patent No. CN 220203351 U), a chimney body is included. A ladder is provided on one side of the chimney body, and an external ring-shaped fixing assembly is provided around the chimney body. A supporting fixing assembly is provided at the bottom of the external ring-shaped fixing assembly. Furthermore, to achieve the purpose of external ring-shaped fixing of the chimney, the external ring-shaped fixing assembly includes a first clamp, with a fixing groove circumferentially formed inside the first clamp. A fixing rod is engaged inside the fixing groove, and a fixing plate is connected above the fixing rod. A mounting base plate is connected to one side of the fixing plate, and a fixing frame is connected to one side of the mounting base plate. The advantages of this invention are that it not only prevents the scaffold from easily swaying or shifting, thus ensuring structural stability and providing a certain degree of protection for personnel, but also facilitates installation on chimneys in practical use. It is highly suitable for chimney construction and overcomes the shortcomings of existing technologies.

[0004] However, in the existing technology, the height of the staff varies and the required working position also varies. If the grandstand is set too low or cannot be adjusted, it will increase the burden on the staff. The inability to adjust according to the needs of users will cause many inconveniences. Therefore, an adjustable height ring-shaped wall-mounted scaffold is designed. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned problems and shortcomings of the existing technology by designing a ring-shaped wall-mounted scaffold.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows:

[0007] A circular wall-mounted scaffold includes a main working body, an annular fixing frame fixedly arranged on the outer ring of the main working body, and a movable component for easy height adjustment installed on the top of the annular fixing frame through multiple hinge seats. A ladder is provided on one side of the main working body.

[0008] The moving assembly includes a first moving plate, a second moving plate, and a telescopic cylinder. The first moving plate and the second moving plate are arranged crosswise, and the outer rings of the first moving plate and the second moving plate are slidably fitted with plate sleeves. The telescopic cylinder is installed on the top of the annular fixed frame, and the output end of the telescopic cylinder is fixedly connected to a connecting plate. Telescopic plates are fixedly installed on both sides of the connecting plate, and the outer sides of the telescopic plates are respectively hinged to the inner sides of the first moving plate and the second moving plate.

[0009] Preferably, the outer ring of the working body is provided with a sliding groove, and an annular moving frame is slidably fitted around the outer ring of the sliding groove.

[0010] Preferably, the outer surface of the annular movable frame is fixedly provided with multiple worktables, and each worktable has connecting blocks welded to both sides, and each connecting block is fixed to the annular movable frame by bolts.

[0011] Preferably, each of the workbenches is welded with a guardrail on its top, and a safety rope is fixedly installed between two of the guardrails.

[0012] Preferably, each workbench has two mounting blocks at its bottom, and a mounting protection seat is fixedly installed between the two mounting blocks. The mounting protection seat has two limiting grooves at its bottom.

[0013] Preferably, both the first movable plate and the second movable plate are provided with a second hinge seat on their tops. The second hinge seat slides within the limiting groove via a slide rail provided on its top, and the slide rail is adapted to the limiting groove.

[0014] Preferably, the bottom of each of the first and second movable plates is hinged to the first hinge seat, and each of the telescopic cylinders is located between the two first hinge seats and the first and second movable plates.

[0015] The beneficial effects achieved by this utility model are:

[0016] By setting up the moving components, activating the telescopic cylinder can raise the connecting plate. The connecting plate, through the telescopic plate, raises the two plate sleeves. As the angle between the first and second moving plates gradually decreases, the hinge seat and slide rail at the top of the first and second moving plates move closer to each other. The thrust of the first and second moving plates raises the worktable. The simultaneous rise of multiple worktables can move the ring moving frame on the opened slide rail, making it convenient to adjust the height according to the needs of the workers.

[0021] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention. Example 1

[0022] like Figure 1-3 As shown, the present invention proposes a ring-shaped wall-mounted scaffold, including a working body 1. A ring-shaped fixing frame 2 is fixedly installed on the outer ring of the working body 1. A movable component 3 for easy height adjustment is installed on the top of the ring-shaped fixing frame 2 through multiple hinge seats 4. A ladder is provided on one side of the working body 1. The movable component 3 includes a movable plate 31, a movable plate 32 and a telescopic cylinder 33. The movable plate 31 and the movable plate 32 are arranged crosswise. Plate sleeves 34 are slidably fitted on the outer rings of the movable plate 31 and the movable plate 32. The telescopic cylinder 33 is installed on the top of the ring-shaped fixing frame 2. A connecting plate 35 is fixedly connected to the output end of the telescopic cylinder 33. Telescopic plates are fixedly installed on both sides of the connecting plate 35. The outer sides of the telescopic plates are respectively hinged to the inner sides of the movable plate 31 and the movable plate 32.

[0023] In this embodiment, an annular fixing frame 2 is fixedly installed on the outer ring of the working body 1. The top of the annular fixing frame 2 is equipped with a movable component 3 that is easy to adjust in height through multiple hinge seats 4. The multiple hinge seats 4 are respectively hinged to the movable plate 31 and the movable plate 32, which can better adjust the height of the movable component 3. By activating the telescopic cylinder 33, the connecting plate 35 can be raised. The connecting plate 35 extends outward through the telescopic plate and drives the two plate sleeves 34 to rise at the same time. The plate sleeves 34 slide on the movable plate 31 and the movable plate 32, so that the angle at the intersection of the movable plate 31 and the movable plate 32 gradually decreases, thereby driving the tops of the movable plate 31 and the movable plate 32 to move closer to each other. It can be adjusted to a convenient working height as needed, avoiding encountering places that are too high to reach, and has strong practicality. Example 2

[0024] like Figure 1-3As shown, the present invention proposes a ring-shaped wall-mounted scaffold. Compared with embodiment 1, this embodiment further includes a groove 5 on the outer ring of the working body 1. A ring-shaped movable frame 6 is slidably fitted on the outer ring of the groove 5. Multiple workbenches 7 are fixedly installed on the outer surface of the ring-shaped movable frame 6. Connecting blocks 8 are welded to both sides of each workbench 7. Each connecting block 8 is fixed to the ring-shaped movable frame 6 by bolts 9. Guardrails 10 are welded to the top of each workbench 7. Safety ropes 11 are fixedly installed between two guardrails 10. A safety rope 11 is installed at the bottom of each workbench 7. There are two mounting blocks 12, and a mounting protection seat 13 is fixedly installed between the two mounting blocks 12. The bottom of the mounting protection seat 13 has two limiting grooves 14. The top of the movable plate 1 31 and the movable plate 2 32 are both provided with hinge seats 2. The hinge seats 2 slide in the limiting grooves 14 through the slide rails provided on the top. The slide rails are adapted to the limiting grooves 14. The bottom of each movable plate 1 31 and movable plate 2 32 is hinged to the hinge seat 4. Each telescopic cylinder 33 is located in the middle position between the two hinge seats 4 and the movable plate 1 31 and movable plate 2 32.

[0025] In this embodiment, the outer ring of the working body 1 is provided with a sliding groove 5, and an annular moving frame 6 is slidably fitted around the outer ring of the sliding groove 5. Multiple workbenches 7 are fixedly installed on the outer surface of the annular moving frame 6. Each workbench 7 has connecting blocks 8 welded to both sides, and each connecting block 8 is fixed to the annular moving frame 6 by bolts 9, thus fixing the workbench 7 to one side of the annular moving frame 6. This makes it convenient for workers to stand on it and work, and also makes it convenient to raise the workbench 7 by the moving component 3. The multiple workbenches 7 allow the annular moving frame 6 to slide on the sliding groove 5. By setting connecting blocks 8 on both sides of the workbench 7 and strengthening the fixation with bolts 9, the fixation between the workbench 7 and the annular moving frame 6 is strengthened. By setting the annular moving frame 6 so that the whole is fitted onto the sliding groove 5 opened in the working body 1, the stability of the device's rise and fall is improved. The guardrail 10 and safety rope 11 are provided to protect the workers. If it is necessary to go from one workbench 7 to another, one can step on the edge of the annular moving frame 6 and hold the safety rope 11 to ensure safety during movement.

[0026] Working principle: In use, the worker climbs to the top of the workbench 7 via a ladder. The guardrail 10 at the top of the workbench 7 provides further protection for the worker. When the height needs to be adjusted according to the work, multiple telescopic cylinders 33 are activated. The telescopic cylinders 33 drive the connecting plate 35 and the telescopic plates on both sides to rise. The connecting plate 35 and the telescopic plates on both sides push the outer plate sleeves 34 to slide and rise on the moving plate one 31 and the moving plate two 32 respectively. At the same time, the telescopic plates on both sides of the connecting plate 35 extend outward. When the two plate sleeves 34 rise at the same time, the intersection angle above the moving plate one 31 and the moving plate two 32 gradually decreases, causing the moving plate one 31 and the moving plate two 32 to drive the two top slide rails to slide in the limiting groove 14. The two slide rails move closer to each other, thereby driving the workbench 7 to rise. The simultaneous rise of multiple workbench 7s can drive the annular moving frame 6 to slide and move upward on the slide groove 5, making it convenient to adjust the height of the worker as needed.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
