Technical Field

[0001] This utility model relates to the field of high-altitude operation technology, specifically to a safety protection high-altitude operation device. Background Technology

[0002] High-altitude work refers to work performed at a height relative to a certain position. According to national regulations, any work performed at a height of 2 meters or more above the reference plane where there is a possibility of falling is called high-altitude work. When working inside a building, if the operation is carried out on a scaffold above 2 meters, it is considered high-altitude work.

[0003] Patent document CN219011898U discloses a high-altitude work safety device, including a high-altitude work frame. A base is fixedly installed at the lower end of the high-altitude work frame, and a rectangular groove is opened at the upper end of the base. Two medium-sized holes are opened at the bottom of the inner wall of the high-altitude work frame. Threaded rods are rotatably installed through the two medium-sized holes of the high-altitude work frame. Limiting circular plates are fixedly installed through the lower circumferential surfaces of the two threaded rods. The limiting circular plates are rotatably sleeved in the middle holes of the high-altitude work frame. A bevel gear is fixedly installed at the lower end of the two threaded rods.

[0004] Although the above application document shows that the protection range of the device is further expanded when the protective frame is moved upward, which greatly increases the safety of users when working at height and avoids dangers for users when working at height, it is very inconvenient to use the device as it requires people to step over the working frame.

[0005] Therefore, a safety protection type of high-altitude work device is proposed to solve the problems mentioned above. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a safety protection high-altitude operation device, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a base, wherein a lifting mechanism is mounted on the top of the base;

[0008] The working mechanism includes an electric slide rail, an electric slider is mounted on the inner wall of the electric slide rail, a first rotating rod is rotatably connected to the top of the electric slider via a bearing, a working frame for working is fixedly connected to the top of the first rotating rod, a support block for sliding is fixedly connected to the bottom of the working frame, and a transmission component for driving the electric slider and the first rotating rod is mounted on the side of the base.

[0009] Preferably, the transmission assembly includes a vertical plate, a second rotating rod is rotatably connected to the side of the vertical plate via a bearing, a second bevel gear is fixedly connected to the side of the second rotating rod, and a first bevel gear is fixedly connected to the bottom of the first rotating rod.

[0010] Preferably, the second rotating rod extends to the left through the vertical plate, a first circular gear is fixedly connected to the left side of the second rotating rod, and a first rack is fixedly connected to the top of the base.

[0011] Preferably, the first bevel gear and the second bevel gear mesh with each other, and the first spur gear meshes with the first rack.

[0012] Preferably, the top of the base is equipped with a rotating device to improve the stability of the working mechanism during lifting.

[0013] Preferably, the rotating device includes a second rack, which is fixedly connected to the top of the electric slider. A third rotating rod is rotatably connected to the side of the electric slide rail via a bearing. A thick rod is fixedly connected to the side of the third rotating rod, and a thin rod is slidably connected to the inner wall of the thick rod. A second spherical gear is fixedly sleeved on the outer wall of the third rotating rod.

[0014] Preferably, the outer walls of the thick rod and the thin rod are fixedly connected with elastic telescopic rods, and the second rack meshes with the Dürer spherical gear.

[0015] Compared with the prior art, this utility model provides a safety protection high-altitude work device, which has the following beneficial effects:

[0016] 1. By activating the electric slide rail and electric slider, and utilizing the meshing transmission of gears and racks, the notch of the work frame is cleverly rotated to the front, facilitating personnel operation without requiring them to step over the work frame. This greatly improves the convenience and safety of operation, saves manpower, and increases work efficiency.

[0017] Second, when the electric slider rises, it drives a series of transmission components, causing the thinner rod to extend from the thicker rod and support the back of the base, enhancing the stability of the equipment during operation. The retraction process is reasonably designed; by lowering the electric slider in conjunction with manually pulling the elastic telescopic rod, the supporting components can be returned to their original positions. This simple operation ensures the compactness and flexibility of the equipment when not in operation. Attached Figure Description

[0026] The working mechanism 2 includes an electric slide rail 21, an electric slider 22 is mounted on the inner wall of the electric slide rail 21, a first rotating rod 23 is rotatably connected to the top of the electric slider 22 via a bearing, a working frame 24 for working is fixedly connected to the top of the first rotating rod 23, a support block 25 for sliding is fixedly connected to the bottom of the working frame 24, and a transmission component for driving the electric slider 22 and the first rotating rod 23 is mounted on the side of the base 1.

[0027] The transmission assembly includes a vertical plate 29, a second rotating rod 28 rotatably connected to the side of the vertical plate 29 via a bearing, a second bevel gear 27 fixedly connected to the side of the second rotating rod 28, and a first bevel gear 26 fixedly connected to the bottom of the first rotating rod 23.

[0028] The second rotating rod 28 extends to the left through the vertical plate 29. The first circular gear 210 is fixedly connected to the left side of the second rotating rod 28, and the first rack 211 is fixedly connected to the top of the base 1.

[0029] The first bevel gear 26 and the second bevel gear 27 mesh with each other, and the first spur gear 210 meshes with the first rack 211.

[0030] When the above-mentioned equipment is used, the electric slide rail 21 and the electric slider 22 are started. During the upward movement of the electric slider 22, the first spur gear 210 is driven to rise. The first spur gear 210 meshes with the first rack 211, causing the first spur gear 210 to rotate clockwise. During the clockwise rotation of the first spur gear 210, the second rotating rod 28 is driven to rotate. The second rotating rod 28 drives the second bevel gear 27 to rotate. The second bevel gear 27 drives the first bevel gear 26 to rotate. The first bevel gear 26 drives the first rotating rod 23 to rotate. The first rotating rod 23 drives the working frame 24 to rotate, rotating the side that originally had the gap for people to sit on to the front of the electric slide rail 21. The working frame 24 drives the support block 25 to rotate, and at the same time, the support block 25 provides support for the working frame 24.

[0031] Example 2

[0032] See Figures 1-4 Based on Embodiment 1, the top of the base 1 is equipped with a rotating device 3 to improve the stability of the working mechanism 2 during lifting.

[0033] The rotating device 3 includes a second rack 31, which is fixedly connected to the top of the electric slider 22. A third rotating rod 32 is rotatably connected to the side of the electric slide rail 21 via a bearing. A thick rod 34 is fixedly connected to the side of the third rotating rod 32. A thin rod 35 is slidably connected to the inner wall of the thick rod 34. A second spherical gear 33 is fixedly sleeved on the outer wall of the third rotating rod 32.

[0034] The outer walls of the thick rod 34 and the thin rod 35 are fixedly connected with an elastic telescopic rod 36, and the second rack 31 meshes with the second spur gear 33.

[0035] In practical use, when the electric slider 22 rises, it drives the second rack 31 to rise. The second rack 31 drives the second sprocket 33 to rotate counterclockwise. The second sprocket 33 drives the third rotating rod 32 to rotate counterclockwise. The third rotating rod 32 drives the thick rod 34 and the thin rod 35 to rotate counterclockwise. When the thin rod 35 slides out of the top range of the base 1, the elastic telescopic rod 36 drives the thin rod 35 to extend from the inner wall of the thick rod 34 to support the back of the base 1. When it needs to be retracted, the electric slider 22 is activated. When the electric slider 22 descends, it drives the second rack 31 to descend. The second rack 31 drives the second sprocket 33 to rotate. When the second sprocket 33 drives the thick rod 34 and the thin rod 35 to move to the back of the base 1, the elastic telescopic rod 36 is manually pulled to retract. At the same time, the electric slider 22 continues to move, and the thick rod 34 and the thin rod 35 return to their original positions.

[0036] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.
