Description

Technical Field

[0001] The utility model relates to the technical field of aerial work equipment, in particular to a multi-adjustable swing mechanism for an aerial work platform. Background Art

[0002] At present, the aerial work platform is an advanced aerial work machinery that can greatly improve the work efficiency, safety and comfort of aerial construction workers and reduce labor intensity. In particular, there is an increasing demand for municipal street lamp maintenance, garden tree pruning and forest harvesting. With the rapid development of my country's economy, aerial work platforms are becoming more and more widely used.

[0003] There is currently a multi-directional adjustment device for a self-propelled single-arm aerial work platform (its authorization announcement number is: CN221607727U). By setting a rotating column, a lifting arm, a work platform, a swing mechanism, and a structure in which the lifting mechanism cooperates with each other, it can simultaneously control the work platform's ability to perform high-altitude lifting and large-angle swinging, so as to achieve a large range and multi-angle position movement, thereby effectively expanding the working space, improving working efficiency, and having the advantages of long moving distance and good flexibility, thereby being able to meet the use needs of high-altitude operations and forest harvesting.

[0004] However, this device has some shortcomings in actual use: the aerial work platform has limited loading space, which limits the types and quantities of tools, equipment or materials that can be carried and operated. It requires frequent lifting and lowering to transport materials, which increases the physical burden and time cost. At the same time, the small space of the aerial work platform makes it inconvenient for aerial workers to operate at high altitudes. Therefore, we proposed a multi-adjustment swing mechanism for the aerial work platform to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Refer to Figure 1-5 , a multi-adjustable swing mechanism for an aerial work platform, comprising a crank arm lift 1, a hydraulic crank arm 2 is provided on the crank arm lift 1, an aerial work platform base 3 is provided on the hydraulic crank arm 2, extension plates 4 are rotatably installed on both side walls of the aerial work platform base 3, two sliding grooves 5 are provided between the aerial work platform base 3 and the two extension plates 4, the same protective frame 6 is movably installed in the corresponding two sliding grooves 5, two activity chambers 7 and installation chambers 9 are respectively provided in the aerial work platform base 3, movable plates 8 are movably installed in the two activity chambers 7, the two movable plates 8 are respectively fixedly connected to the corresponding protective frames 6, an extension driving mechanism for the two movable plates 8 is provided in the installation chamber 9, two limit plates 12 are respectively fixedly installed on the bottom side of the aerial work platform base 3, an elastic latch mechanism for the extension plate 4 is provided on one side of the protective frame 6, and a protective mechanism is provided on the top side of the aerial work platform base 3.

[0023] Furthermore, there are two protective frames 6 , which are symmetrically arranged. By moving the two protective frames 6 on the aerial work platform base 3 away from each other, the cargo space can be extended and expanded.

[0024] Furthermore, the extension drive mechanism includes a dual-axis motor 10 and a screw rod 11. The dual-axis motor 10 is fixedly installed in the installation chamber 9. The two output shafts of the dual-axis motor 10 are fixedly installed with one end of the screw rod 11. The other ends of the two screw rods 11 are respectively threaded through the outside of the relative movable plates 8 and are rotatably installed on one side of the inner wall of the corresponding movable chamber 7. The threads of the two screw rods 11 have opposite rotation directions. By starting the dual-axis motor 10, the two screw rods 11 are rotated, thereby driving the two movable plates 8 to slide in the corresponding movable chambers 7 and move away from each other.

[0025] Furthermore, two limiting plates 12 are respectively attached to the bottom sides of the corresponding extension plates 4 , and the limiting plates 12 are arranged in a U-shaped structure; by the limiting plates 12 being attached to the bottom sides of the extension plates 4 , the extension plates 4 are limited.

[0026] Specifically, the elastic latch mechanism includes a guide rod 13, an upper horizontal plate 14, a lower horizontal plate 15, an L-shaped latch plate 16 and a spring 17. Two guide rods 13 are movably installed on one side wall of the protective frame 6. The top and bottom ends of the two guide rods 13 are fixedly installed with the upper horizontal plate 14 and the lower horizontal plate 15 respectively. Two L-shaped latch plates 16 are fixedly installed on the bottom side of the lower horizontal plate 15. The L-shaped latch plates 16 are adapted to the sliding groove 5. Two springs 17 are fixedly installed between the bottom side of the upper horizontal plate 14 and the protective frame 6 respectively. By pulling the two upper horizontal plates 14 upward, the two springs 17 are subjected to force to deform and stretch, and the two L-shaped latch plates 16 on the bottom side of the lower horizontal plate 15 are driven by the two guide rods 13 to disengage from the two sliding grooves 5 on the extension plate 4, so as to facilitate the flipping and adjustment of the extension plate 4.

[0027] Specifically, the protection mechanism includes a protection rod frame 18, a rod chamber 19 and a frame rod 20. Two protection rod frames 18 are fixedly installed on the top side of the aerial work platform base 3. A plurality of rod chambers 19 are respectively opened on the protection rod frame 18. Frame rods 20 are movably installed in the plurality of rod chambers 19. One end of the plurality of frame rods 20 is fixedly installed on one side of the corresponding protection frame 6. When the two protection frames 6 move away from each other, the plurality of frame rods 20 on the protection frame 6 slide in the corresponding rod chambers 19 respectively.

[0028] During use: When aerial work is required, the operator stands on the aerial work platform base 3, and pulls up the two upper horizontal plates 14 in turn, so that the two springs 17 are stressed and deformed and stretched, and the two L-shaped latch plates 16 on the bottom side of the lower horizontal plate 15 are driven by the two guide rods 13 to disengage from the two sliding grooves 5 on the extension plate 4, so that the two extension plates 4 can be turned 90 degrees and fit on the corresponding limit plates 12. After that, the two-axis motor 10 is started to rotate the two screw rods 11, thereby driving the two movable plates 8 to slide in the corresponding movable chambers 7 and move away from each other, thereby driving the two protective frames 6 to slide in the corresponding movable chambers 7 and move away from each other. The two corresponding sliding grooves 5 slide and move away from each other, so that the two protection frames 6 are respectively extended to the position between the aerial work platform base 3 and the extension plate 4, so as to limit and fix the two extension plates 4. At this time, the multiple frame rods 20 on the two protection frames 6 slide outward in the corresponding rod chambers 19 on the two protection rod frames 18, respectively. By extending the extension plates 4 at both ends of the aerial work platform base 3, the loading space of the aerial work platform base 3 is increased, and the need for frequent up and down lifting to transport materials due to insufficient loading space of the aerial work platform base 3 is reduced, thereby improving the convenience of aerial operators during aerial operations.
