Description

Technical Field

[0001] The utility model relates to the field of aerial work vehicles, and more specifically to an oil-electric dual-purpose aerial work vehicle. Background Art

[0002] Aerial work vehicles can generally be divided into vehicle-mounted aerial work vehicles and self-propelled aerial work vehicles. For self-propelled aerial work vehicles, although the wheelbase at the bottom is larger, it can increase the support surface and improve the stability of the aerial work platform to a certain extent. However, when the lifting distance of the working platform on the top of the aerial work vehicle is high, the working platform at high altitude will inevitably shake, which makes the workers feel less safe when standing on the working platform. Therefore, we proposed a dual-purpose oil-electric aerial work vehicle to solve the above problems. Utility Model Content

[0024] Embodiment 1:

[0025] See also Figure 1-Figure 4 A dual-purpose oil-electric aerial work vehicle comprises a dual-purpose oil-electric work vehicle body 1, both sides of the dual-purpose oil-electric work vehicle body 1 are provided with outrigger mechanisms 2 of the same structure, and the two outrigger mechanisms 2 are arranged opposite to each other, the outrigger mechanisms 2 comprise a base plate 3 and an outrigger seat plate 4 fixedly mounted on both sides of the dual-purpose oil-electric work vehicle body 1 by a plurality of bolts, the outrigger seat plate 4 comprises a U-shaped section 401 and an arc section 402, the U-shaped section 401 is internally rotatably connected with two outrigger bodies 6 by two main pin shafts 5, a plurality of limiting holes 1 403 are equidistantly provided on the arc section 402, and limiting holes 2 are provided on both outrigger bodies 6, and the limiting holes 2 are connected to the corresponding limiting holes 1 403 by limiting pins 7;

[0026] A group of arms 8 are fixedly welded on the body 1 of the oil-electric dual-purpose working vehicle, and the top of the group of arms 8 is rotatably connected by a pry bar 9. An installation cavity 101 is opened inside the body 1 of the oil-electric dual-purpose working vehicle located on one side of the arm 8. A hydraulic cylinder 10 is arranged inside the installation cavity 101. The bottom of the hydraulic cylinder 10 is rotatably connected inside the installation cavity 101. The telescopic rod at the top of the hydraulic cylinder 10 is rotatably connected to the top of the pry bar 9. A group of ear pieces 404 are fixedly welded on the top of the arc segment 402. A group of ear pieces 404 are rotatably connected to the bottom of the pry bar 9 by a latch 11. The base A set of ear pieces 2 301 and a set of ear pieces 3 405 are fixedly welded between the plate 3 and the leg seat plate 4, respectively; a rotating shaft 12 is fixedly welded inside a set of ear pieces 305, and both ends of the rotating shaft 12 respectively penetrate to the outside of a set of ear pieces 2 301, and the connection between the rotating shaft 12 and the ear pieces 2 301 is rotatably connected through bearings, and both ends of the rotating shaft 12 are fixedly welded with limit gears 13, and the outsides of the two limit gears 13 are meshed with limit members 14, and one end of the limit member 14 is rotatably connected with a connecting shaft, and one end of the connecting shaft is fixedly welded to the outside of the corresponding ear piece 2 301.

[0027] The operating principle of this oil-electric aerial work vehicle is:

[0028] First, unplug the limit pins 7 on the two leg mechanisms 2, manually unfold the two leg bodies 6 on the two leg mechanisms 2, and when the unfolding angle reaches the required angle, insert the limit pin 7 back between the corresponding limit hole 2 and the limit hole 1 403 to achieve the effect of fixing the leg mechanism 2 after unfolding, and then respectively push the two limit members 14 on the two leg mechanisms 2 to disengage from the limit of the corresponding limit gear 13. At this time, the hydraulic cylinder 10 inside the installation cavity 101 can be controlled to work, and the top of the pry bar 9 can be pushed upward, thereby forcing the leg seat plate 4 to deflect downward through the connection of the rotating shaft 12, so that the two leg bodies 6 on the installed leg seat plate 4 can contact and support the ground, and after the support is completed, release the two limit members 14 to complete the limit of the corresponding limit gear 13. At this time, the support work can be completed, and then the staff can board the top working platform of the oil-electric dual-purpose work vehicle body 1 to perform aerial work;

[0029] When the oil-electric dual-purpose aerial work vehicle needs to be transferred over a long distance, it is only necessary to pull out the pin 11 at the bottom of the pry bar 9 to disconnect the bottom of the pry bar 9 from the top of the arc section 402, and then remove several bolts on the base plate 3. At this time, the base plate 3 of the outrigger mechanism 2, the outrigger seat plate 4 and the outrigger body 6 can be disconnected from the oil-electric dual-purpose aerial work vehicle body 1, reducing the overall volume and facilitating the transportation work.

[0030] Embodiment 2:

[0031] In view of the above embodiment 1, for further description, refer to Figure 1 and Figure 2The end of one end of the leg body 6 is fixedly mounted with a contact base 601, and the distance between a group of arms 8 is greater than the outer wall diameter of the telescopic rod at the top of the hydraulic cylinder 10.

[0032] By setting up a contact base 601, the contact area between one end of the leg body 6 and the ground can be increased, thereby improving the stability of the supporting structure. By making the distance between a group of supporting arms 8 larger than the outer wall diameter of the telescopic rod at the top of the hydraulic cylinder 10, interference between the telescopic rod at the top of the hydraulic cylinder 10 and a group of supporting arms 8 during telescoping can be prevented.

[0033] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
