Description

Technical Field

[0001] This utility model relates to the field of aerial work platforms, and in particular to a protective device for aerial work platforms. Background Technology

[0002] Aerial work platforms are widely used in construction, equipment installation, and maintenance. Existing aerial work platforms are typically equipped with folding outriggers, which are attached to a trolley. While this design improves the platform's flexibility and mobility to some extent, the large size of the trolley creates a distance between the platform and the area requiring installation or maintenance. During equipment repair, the worker is often suspended in mid-air, and the gap between the repair area and the platform makes it easy for tools to slip from their hands or for parts to fall. If workers are standing below, this can easily lead to accidents. Furthermore, the fixed height of the platform's edge guardrails reduces their protective effectiveness for taller workers, posing a safety hazard. Summary of the Invention

[0003] This utility model aims to address the shortcomings of existing technologies by providing a protective device for aerial work platforms.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a protective device for an aerial work platform, comprising support plates fixed to the four sides of the base plate of the work platform, a groove on the top of the support plate, an airbag inside the groove, and several support rods rotatably connected to the top edge of the support plate. The four corner prisms of the guardrail frame of the work platform have trapezoidal cross-sections, and adjusting rods are slidably provided inside the prisms. A fixing mechanism is provided between the adjusting rods and the prisms. A rectangular frame is provided on the top of the four adjusting rods, and a break is provided on the side of the rectangular frame near the guardrail frame with the door, and a connecting rod mechanism is provided inside the break.

[0005] Specifically, one end of the support rod is equipped with a pivot, which is rotatably connected to the top of the support plate.

[0006] Specifically, the inner side of the adjusting rod is provided with a T-shaped slider, and the prism is provided with a groove corresponding to the slider, and the slider slides in the groove.

[0007] Specifically, the fixing mechanism includes several threaded holes evenly spaced on both sides of the slide groove, and the slider is threaded with fixing bolts corresponding to the threaded holes. The adjusting rod is fixed by screwing the fixing bolts into the threaded holes.

[0008] Specifically, the linkage mechanism includes telescopic rods that are telescopically disposed inside the rods on both sides of the break. One telescopic rod has a sleeve at its end and the other telescopic rod has a spring buckle at its end. The telescopic rod is inserted into the sleeve and fixed by the spring buckle.

[0009] In particular, the aerial work platform vehicle is equipped with an air pump connected to the airbag.

[0010] The beneficial effects of this utility model are as follows: By setting up a support plate, groove, airbag, and support rod, the airbag can easily seal the space gap between the maintenance part and the work platform, preventing maintenance tools or parts from falling directly to the ground and avoiding safety accidents. At the same time, the support rod can provide certain support for the airbag, increasing stability, and the support rod and airbag can be easily stored on the support plate, avoiding space occupation when not in use. By setting up an adjusting rod, rectangular frame, fixing mechanism, and linkage mechanism, an adjustable rectangular frame is added to the guardrail frame, which can be adjusted according to the height of the workers, enhancing the protective effect and reducing safety hazards.

[0016] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0018] like Figures 1-4As shown, a protective device for an aerial work platform includes support plates 2 fixed to the four sides of the base plate 1 of the work platform. The top of the support plate 2 is provided with a groove 3, and an airbag 4 is provided in the groove 3. An air pump connected to the airbag 4 is provided inside the aerial work platform. Several support rods 5 are rotatably connected to the top edge of the support plate 2. One end of the support rod 5 is provided with a pivot 10, which is rotatably connected to the top of the support plate 2. The airbag 4 can easily seal the space gap between the maintenance part and the work platform, preventing maintenance tools or parts from falling directly to the ground and avoiding safety accidents. At the same time, the support rods 5 can provide a certain support for the airbag 4, increasing stability. Furthermore, the support rods 5 and the airbag 4 can be easily stored on the support plate 2, avoiding space occupation when not in use.

[0019] The guardrail frame 6 of the work platform has four corner prisms with trapezoidal cross sections, and an adjusting rod 7 is slidably installed inside the prism. The adjusting rod 7 has a T-shaped slider 11 inside, and the prism has a groove corresponding to the slider 11. The slider 11 is slidably installed in the groove. A fixing mechanism is provided between the adjusting rod 7 and the prism. The fixing mechanism includes several threaded holes equally spaced on both sides of the groove. The slider 11 is threaded with a fixing bolt 12 corresponding to the threaded hole. The adjusting rod 7 is fixed by screwing the fixing bolt 12 into the threaded hole. The top of the four adjusting rods 7 is provided with a rectangular frame 8, and the rectangular frame 8 has a break 9 on the side of the guardrail frame 6 with the door. A linkage mechanism is provided in the break 9. The linkage mechanism includes telescopic rods 13 that are telescopically installed inside the rods on both sides of the break 9. One telescopic rod 13 has a retainer 14 at its end, and the other telescopic rod 13 has a spring buckle at its end. The telescopic rod 13 is inserted into the retainer 14 and fixed by the spring buckle. An adjustable rectangular frame 8 is added to the guardrail frame 6 to facilitate adjustment according to the height of the staff, thereby enhancing the protective effect and reducing safety hazards.

[0020] When this utility model is in operation, the worker enters the platform, adjusts the height of the rectangular frame 8 as needed, and then fixes it with the fixing bolts 12. After adjustment, the two telescopic rods 13 are snapped together. After the platform is moved to the maintenance height, the support rod 5 is rotated to the outside of the support plate 2, and the air pump is started to inflate the airbag 4 until the gap is sealed. This utility model has good protective effect and is easy to use.
