Description

Technical Field

[0001] This utility model relates to the field of aerial work platform technology, specifically a safety protection device for aerial work platforms. Background Technology

[0002] Aerial work platforms are mobile high-altitude operations used in various industries for tasks such as high-altitude work, equipment installation, and maintenance. Chinese Patent No. CN220245489U discloses a protective device for aerial work platforms, relating to the field of aerial work platform technology. This invention, by incorporating a protective net and a protective plate, utilizes a controller to operate a servo motor when the work platform is raised to a height via a lifting device. The servo motor drives a rope winding shaft, which in turn drives a rope winding drum, thereby unfolding the protective net via a steel wire rope. This significantly improves safety, preventing workers from accidentally dropping tools or parts from the equipment during maintenance, thus protecting them from injury.

[0003] However, the aforementioned publicly available solutions have the following shortcomings: While multiple adjustable safety nets can prevent maintenance tools from slipping from the workers' hands or parts from falling from the maintenance equipment, they cannot protect maintenance personnel on the high-altitude work platform. Although maintenance personnel wear safety helmets, they will still be harmed if objects fall from a height, resulting in low safety. Utility Model Content

[0016] Example 1

[0017] like Figures 1 to 3 As shown, this utility model proposes a safety protection device for aerial work platforms, including a work platform 2, a fence 202, an adjustment mechanism, a protective canopy 4, and a buffer mechanism. A lifting vehicle 1 is installed at the bottom of the work platform 2. The lifting vehicle 1 is existing technology and can move the work platform 2 and adjust its height. The fence 202 is set at the top of the work platform 2, and a door 203 is hinged to the fence 202. The other end of the door 203 is detachably connected to the fence 202 by a latch. The adjustment mechanism is set on the fence 202. The protective canopy 4 is installed at the top of the adjustment mechanism. The protective canopy 4 can be adjusted in height along the fence 202 and rotated in the vertical direction by the adjustment mechanism. The buffer mechanism is set on the protective canopy 4. The buffer mechanism consists of a buffer plate 5 installed on the protective canopy 4 and a buffer assembly installed between the buffer plate 5 and the protective canopy 4. The buffer assembly consists of a buffer spring 501 and a damping block 502.

[0018] Furthermore, a protective plate 201 is provided at the top edge of the work platform 2. The open end of the protective plate 201 is connected to the enclosure 202, and the bottom end of the door 203 is slidably connected to the top of the work platform 2.

[0019] Furthermore, a rubber seat 503 is installed at the top of the buffer plate 5 to protect the buffer plate 5 and extend its service life.

[0020] Furthermore, the adjustment mechanism includes a support cylinder 3, a support frame 301, a U-shaped rod 304, and an ear seat 401; two sets of support cylinders 3 are provided, and the two sets of support cylinders 3 are symmetrically installed on the enclosure 202, with the bottom end of the support cylinder 3 connected to the top end of the working platform 2; the support frame 301 is slidably connected to the inner wall of the support cylinder 3, and the support frame 301 and the support cylinder 3 are connected by a threaded rod; multiple sets of adjustment grooves 302 are provided on the support frame 301, and the threaded rod is threadedly connected to the adjustment grooves 302; two sets of stabilizing frames 303 are symmetrically installed on the support frame 301. The other end is slidably inserted into the enclosure 202 to improve the installation stability of the support cylinder 3; the U-shaped rod 304 is slidably inserted into the top of the support cylinder 3, and an elastic element 305 is installed between the U-shaped rod 304 and the support cylinder 3. The elastic element 305 is a spring. One end of the elastic element 305 is connected to the support cylinder 3, and the other end is connected to the U-shaped rod 304; two sets of ear seats 401 are provided. The two sets of ear seats 401 are symmetrically installed at the bottom of the protective shed 4. The protective shed 4 is rotatably connected to the corresponding support cylinder 3. The ear seat 401 is provided with an insertion hole 402, and the U-shaped rod 304 is inserted into the insertion hole 402.

[0021] Furthermore, a rotating shaft 403 is installed on the ear seat 401, the rotating shaft 403 is rotatably connected to the support cylinder 3, and a stabilizing element 404 is sleeved on the outside of the rotating shaft 403. The stabilizing element 404 is a spring and abuts between the ear seat 401 and the support cylinder 3.

[0022] In this embodiment, rotating the bolt rod away from the support frame 301 allows the support frame 301 to slide up or down along the support cylinder 3 to a suitable height. Then, rotating the threaded rod connects it to the adjustable groove 302 on the support frame 301, thereby adjusting the height of the protective canopy 4 relative to the work platform 2. This reduces space occupation, facilitates storage, and accommodates workers of different heights. The enclosure 202 and door 203 enhance the safety of construction workers. The enclosure 202 and door 203 together seal the top edge of the work platform 2, preventing tools from falling off during work. The protective canopy 4 provides shelter and protection for workers, preventing interference or injury from falling objects. When objects fall, they hit the buffer plate 5, where the rubber seat 503 cushions some of the impact, preventing direct impact. The buffer plate 5 generates significant noise and extends its service life. The buffer spring 501 and damping block 502 help to buffer part of the impact force, extending the service life of the protective canopy 4 and preventing secondary injuries caused by falling objects hitting the buffer plate 5 and then bouncing back down. The protective canopy 4 catches falling objects. After construction is completed, the protective canopy 4 is lowered to a suitable height relative to the working platform 2. The U-shaped rod 304 is slid along the ear seat 401, causing the elastic element 305 to be stretched. Then, the insertion end of the U-shaped rod 304 moves away from the insertion hole 402 on the ear seat 401. At this time, the protective canopy 4 can be pushed to make the rotating shaft 403 rotate along the support cylinder 3 at a suitable angle. Under the action of the stabilizer 404, the protective canopy 4 will not rotate uncontrollably along the support cylinder 3. When the protective canopy 4 is tilted relative to the support cylinder 3, the falling objects will be discharged into the discharge end of the protective canopy 4, and the workers can clean it.

[0023] Example 2

[0024] like Figure 1 and Figure 3 As shown, the safety protection device for aerial work platforms proposed in this utility model, compared with Embodiment 1, has a material receiving component at one end of the protective shed 4. The material receiving component includes a baffle 405 and a collection box 407. The baffle 405 is installed at the top of the protective shed 4. The connecting shell 406 is connected to the discharge end of the protective shed 4. The collection box 407 is slidably connected to the inner wall of the connecting shell 406, and the collection box 407 is detachably connected to the connecting shell 406 through a threaded rod.

[0025] In this embodiment, when the protective canopy 4 is tilted relative to the support cylinder 3, the falling objects received on the protective canopy 4 can enter the collection box 407, or the staff can guide the falling objects into the collection box 407, slide the collection box 407 outward along the connecting shell 406 to remove the collection box 407 and clean up the falling objects.

[0026] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
