Description

Technical Field

[0001] The utility model relates to the technical field of high-altitude safety protection, in particular to a safety protection device for an aerial work vehicle working platform. Background Art

[0002] Aerial platforms, currently essential tools for modern construction and maintenance, often utilize a scissor-type telescopic frame as the core lifting mechanism for their safety protection. While this scissor-type telescopic frame effectively achieves vertical lift, its single-point or limited-point connection to the platform's base renders the platform lacking sufficient lateral stability and wind resistance during aerial work. This not only increases safety risks during operations but also impacts efficiency and operator comfort.

[0003] Traditional aerial work platforms feature a fixed design, making this a particularly limiting feature when faced with tasks requiring the placement of long or unusually shaped items. For example, operations like pipe laying and cable installation often require carrying long materials or tools up to the platform. However, since the platform's guardrails are often fixed, this can make it difficult to place items on the platform. Even if these items are placed, they often extend beyond the guardrails, posing a safety hazard. Utility Model Content

[0023] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention. On the contrary, the embodiments of the present invention include all variations, modifications, and equivalents that fall within the spirit and scope of the appended claims.

[0024] A safety protection device for an aerial work platform of an aerial work vehicle according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] like Figure 1-Figure 3As shown, a safety protection device for an aerial work vehicle working platform according to an embodiment of the present invention includes a base plate 1, a mounting device 2, a lifting device 3 and an operating table 4, wherein the mounting device 2 includes two groups of mounting components 21, wherein the two groups of mounting components 21 are respectively arranged at the top of the base plate 1 and the bottom of the operating table 4, and the lifting device 3 includes a connecting component 31 and a cylinder 32, wherein the connecting component 31 is movably arranged between the two mounting components 21, and the cylinder 32 is connected to both ends of the connecting component 31.

[0026] Among them, it can be understood that the operation of the cylinder 32 drives the connecting component 31 to move inside the two groups of mounting components 21, thereby realizing the lifting of the connecting component 31. When the connecting component 31 is lifted up and down, it drives the operating platform 4 to lift up and down synchronously. The two groups of mounting components 21 adopt precise guide rails and sliding mechanisms to ensure that the connecting component 31 can slide smoothly and steadily inside the two groups of mounting components 21 during the lifting process, effectively reducing the safety hazards caused by shaking and greatly improving the stability of the working platform.

[0027] In one embodiment of the present invention, Figure 2 As shown, the two sets of mounting components 21 each include two fixed sliding blocks 211 and two bearing blocks 212, wherein the two fixed sliding blocks 211 are respectively arranged on the top of the base plate 1 and the bottom of the operating table 4, and the two bearing blocks 212 are respectively arranged on the top of the base plate 1 and the other side of the bottom of the operating table 4.

[0028] It can be understood that the two fixed sliding blocks 211 and the two bearing blocks 212 are fixedly connected to the base plate 1 and the operating table 4 respectively, and are connected to the connecting component 31 at the same time, which can ensure that the connecting component 31 remains stable during the up and down lifting process.

[0029] In one embodiment of the present invention, Figure 3 As shown, the connecting assembly 31 includes two groups of sliding rods 311, two groups of connecting rods 312 and multiple groups of scissor-type telescopic frames 313, wherein the two groups of sliding rods 311 are respectively slidably arranged in two fixed sliding blocks 211 on the top of the base plate 1 and one side of the bottom of the operating table 4, and the two groups of telescopic connecting rods 312 are respectively rotatably arranged in two bearing blocks 212 on the top of the base plate 1 and the other side of the bottom of the operating table 4, and the upper and lower ends of the multiple groups of scissor-type telescopic frames 313 are respectively connected to the two groups of sliding rods 311 and the two ends of the two groups of connecting rods 312, one end of the cylinder 32 is movably connected to the connecting rod of the two connecting rods 312 located on the top side of the base plate 1, and the other end of the cylinder 32 is movably connected to the connecting rod of the two connecting rods 312 located on the bottom side of the operating table 4.

[0030] Among them, it can be understood that when the cylinder 32 runs forward, it will drive the connecting rod 312 to slide forward in the fixed sliding block 211. When the connecting rod 312 slides forward in the fixed sliding block 211, it will drive multiple groups of scissor-type telescopic frames 313 to be lifted upward synchronously. When the cylinder 32 retracts back, it will drive the connecting rod 312 to slide backward in the fixed sliding block 211, and at the same time drive multiple groups of scissor-type telescopic frames 313 to descend.

[0031] In one embodiment of the present invention, Figure 1 As shown, protective guardrails 41 are provided on both sides of the top of the operating platform 4, and a movable baffle 42 is provided at the other end of the operating platform 4.

[0032] It is understandable that when large items need to be placed, the movable baffle 42 is bent outward so that the movable baffle 42 drops outward, thereby opening up the two sides of the operating table 4 and enabling longer items to be placed stably.

[0033] In one embodiment of the present invention, Figure 2 As shown, a safety operation indicator light 5 is provided on one side of the operating platform 4 and the base plate 1.

[0034] It is understandable that even when working at night, the operating console 4 and the safety operation indicator light 5 on one side of the base plate 1 can provide an operation warning to prevent pedestrians from accidentally touching the device.

[0035] Specifically, in the actual implementation process, when large items need to be placed, the movable baffle 42 is bent outward, so that the movable baffle 42 drops outward, so that the two sides of the operating table 4 are opened, and longer items can be placed stably. When the cylinder 32 runs forward, it will drive the connecting rod 312 to slide forward in the fixed sliding block 211. When the connecting rod 312 slides forward in the fixed sliding block 211, it will drive multiple groups of scissor-type telescopic frames 313 to be lifted upward synchronously. When the cylinder 32 retracts, it will drive the connecting rod 312 to slide backward in the fixed sliding block 211, and at the same time drive multiple groups of scissor-type telescopic frames 313 to descend. The two fixed sliding blocks 211 and the two bearing blocks 212 are fixedly connected to the base plate 1 and the operating table 4 respectively, and are connected to the connecting assembly 31 at the same time, which can ensure that the connecting assembly 31 remains stable during the up and down lifting process.

[0036] In summary, the embodiment of the utility model is a safety protection device for an aerial work vehicle working platform, which is provided with a mounting device. The mounting device is specially customized for a scissor-type telescopic frame, and adopts a precise guide rail and a sliding mechanism to ensure that the scissor-type telescopic frame can slide steadily and smoothly inside the device during the lifting process, effectively reducing the safety hazards caused by shaking, and greatly improving the stability of the working platform. At the same time, the operating table can be flexibly adjusted, and the operator can adjust the operating table according to the actual work needs and the situation to adapt to the placement requirements of items of different sizes, so as to improve work efficiency.
