Technical Field

[0001] This utility model relates to the field of aerial work platform technology, and in particular to an expandable working platform for aerial work platforms. Background Technology

[0002] Working at height often requires multiple operations within a certain area. If the platform is of fixed size, workers must frequently descend, move the chassis, reposition the boom, and ascend again to reach slightly farther points. Furthermore, work sites often contain various obstacles such as pipes, beams, supports, eaves, and trees. Fixed platforms may be blocked by these obstacles, preventing access to the work points; therefore, expandable platforms are necessary. Utility Model Content

[0005] The extended platform includes: an extended base plate, which is slidably mounted above the main base plate; sliders are fixedly mounted on both sides of the extended base plate; protrusions on the inner side of the sliders are slidably mounted in the slide groove; ear plates are fixedly mounted on the bottom of the extended base plate; and the front end of the hydraulic rod of the hydraulic cylinder is fixedly connected to the ear plates.

[0006] The auxiliary support structure includes a pair of linkage mechanisms, which include a first link and a second link. The first link and the second link have the same structure. One end of the first link and the second link are provided with a bent portion. One end of the first link is hinged to the bottom of the extended base plate, and the other end of the first link with the bent portion is hinged to the other end of the second link with the bent portion. The other end of the second link is hinged to the front end of the main base plate.

[0007] Furthermore, a limiting post is provided on the outer side of the slider, and a limiting groove is provided on the inner side of the side plate, with the limiting post slidably installed in the limiting groove.

[0008] Furthermore, a connector is fixedly provided at the bottom of the tray.

[0018] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] like Figures 1-4 As shown, an expandable working platform for an aerial work vehicle includes: a pallet 1, a main base plate 2, side plates 3, an extension platform 4, a hydraulic cylinder 5, and an auxiliary support structure; the main base plate 2 and the side plates 3 are fixedly mounted on the pallet 1, the side plates 3 are located on both sides of the main base plate 2, the main base plate 2 has a concave groove 20 in the middle, and sliding grooves 21 are located on both sides of the main base plate 2; the cylinder body of the hydraulic cylinder 5 is fixedly mounted inside the concave groove 20.

[0021] The extended platform 4 includes: an extended base plate 40, which is slidably mounted above the main base plate 2; sliders 41 are fixedly mounted on both sides of the extended base plate 40; protrusions on the inner sides of the sliders 41 are slidably mounted in the slide groove 21; and ear plates 42 are fixedly mounted on the bottom of the extended base plate 40. The front end of the hydraulic rod of the hydraulic cylinder 5 is fixedly connected to the ear plates 42. The extension and retraction of the hydraulic cylinder 5 causes the extended platform 4 to extend or retract above the main base plate 2, realizing expansion and retraction. The sliders 41 slide in the slide groove 21 to achieve limiting.

[0022] The auxiliary support structure includes a pair of linkage mechanisms, each comprising a first link 6 and a second link 7. The first link 6 and the second link 7 have identical structures. One end of each link has a bent portion. One end of the first link 6 is hinged to the bottom of the extended base plate 40, and the other end with the bent portion is hinged to the bent end of the second link 7. The other end of the second link 7 is hinged to the front end of the main base plate 2. When the hydraulic cylinder 5 retracts, the extended base plate 40 compresses the linkage mechanism, reducing the angle between the first link 6 and the second link 7. When the hydraulic cylinder 5 extends, the extended base plate 40 extends the linkage mechanism, increasing the angle between the first link 6 and the second link 7.

[0023] A limiting post 43 is provided on the outer side of the slider 41, and a limiting groove is provided on the inner side of the side plate 3. The limiting post 43 is slidably installed in the limiting groove to further limit the slider 41.

[0024] A connector 10 is fixedly installed at the bottom of the pallet 1. It is used to connect the telescopic arm or telescopic fork system.

[0025] Each side panel 3 is equipped with a main guardrail 30, and the rear end of the main base plate 2 is equipped with an opening and closing door.

[0026] The extended platform 4 is provided with extended guardrails 44 at the front end and on both sides.

[0027] The steps of using this utility model are as follows: After the working platform is raised to a suitable position, the hydraulic cylinder 5 extends and drives the extended platform 4 to extend above the main base plate 2. The slider 41 slides in the slide groove 21 to achieve the limit. The extended base plate 40 drives the linkage mechanism to extend. The included angle between the first link 6 and the second link 7 increases, thereby supporting and protecting the extended platform 4. The hydraulic cylinder 5 shortens and drives the extended platform 4 to move in the opposite direction to achieve the retraction.

[0028] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any improvements made using the inventive concept and technical solution of the present invention, or direct application to other situations without modification, are all within the protection scope of the present invention.
