Technical Field
[0001] The utility model relates to an outrigger with a retraction detection function, belonging to the field of aerial work vehicles. Background Art
[0002] Aerial work vehicles have long been widely used in the fields of electricity, gardening, municipal administration, urban lighting, etc. Aerial work vehicles in the above-mentioned fields, the current aerial work vehicles do not have the outrigger retraction detection function. Most of them observe whether the outriggers are retracted, so they cannot confirm whether the outriggers are in a fully retracted state, and are very unsafe when driving on the road. If the outriggers are not fully retracted, not only will the outriggers or the frame structure be damaged, but the driving speed is too fast and it is likely to cause the vehicle to overturn.

DETAILED DESCRIPTION
[0016] The present invention will be further described in detail below with reference to the accompanying drawings and through examples. The following examples are provided to explain the present invention, but the present invention is not limited to the following examples.
[0017] Example
[0018] See also Figures 1 to 4As shown, it should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the utility model, so they have no substantial technical significance. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects and purposes that can be achieved by the utility model, should still fall within the scope of the technical content disclosed by the utility model. At the same time, if there are references to terms such as "upper", "lower", "left", "right", "middle" and "one" in this specification, they are only for the convenience of description, and are not used to limit the scope of the implementation of the utility model. The change or adjustment of their relative relationship, without substantially changing the technical content, should also be regarded as the scope of the implementation of the utility model.
[0019] The outrigger with a retraction detection function in this embodiment includes an outrigger fixing frame 1, an outrigger rotating frame 2, an electric cylinder 4, a detection switch 6, a detection switch bracket 7 and a detection block 8. The outrigger fixing frame 1 is installed at the bottom of the frame beam 5, the electric cylinder 4 is connected to the outrigger control switch 14, the retraction indicator light 13 is connected to the detection switch 6, and the outrigger control switch 14 and the retraction indicator light 13 are both installed on the outrigger operating panel 12.
[0020] One side of the leg fixing frame 1 in this embodiment is rotatably connected to one end of the leg rotating frame 2, the other end of the leg rotating frame 2 is rotatably connected to one end of the electric cylinder 4, the other end of the leg rotating frame 2 is installed with a leg seat 3, the other end of the electric cylinder 4 is rotatably connected to the other side of the leg fixing frame 1, the detection switch bracket 7 is installed on the leg fixing frame 1, the detection switch 6 is installed on the detection switch bracket 7, the detection stop block 8 is installed on the leg rotating frame 2, and the detection switch 6 cooperates with the detection stop block 8.
[0021] That is to say, one side of the leg fixing frame 1 is rotationally connected to one end of the leg rotating frame 2 through the No. 1 pin shaft 9, the other end of the leg rotating frame 2 is rotationally connected to one end of the electric cylinder 4 through the No. 2 pin shaft 10, the other end of the electric cylinder 4 is rotationally connected to the other side of the leg fixing frame 1 through the No. 3 pin shaft 11, and the No. 2 pin shaft 10 penetrates the leg seat 3.
[0022] Specifically, the outrigger can realize the retraction detection function. Before performing aerial work, the outrigger is in a retracted state, and the retraction indicator light 13 is on. When aerial work is required, the electric cylinder 4 is turned on through the outrigger control switch 14 to extend the outrigger rotating frame 2. The outrigger seat 3 is in a grounded state, and the retraction indicator light 13 is off. At this time, aerial work can be performed normally.
[0023] When the aerial work is completed and the vehicle is to be retracted, the electric cylinder 4 is turned on through the outrigger control switch 14 to retract the outrigger rotating frame 2, the outrigger seat 3 is in a lift-off state, and the retraction indicator light 13 is on. The retraction detection device is in a working state, and the distance between the detection switch 6 and the detection block 8 is in the retraction state detection range of the outrigger rotating frame 2, and the aerial work vehicle can travel or move.
[0024] The outrigger control switch 14 turns on the electric cylinder 4 to retract the outrigger rotating frame 2. Assuming that the outrigger seat 3 is off the ground, but the outrigger rotating frame 2 is not fully retracted, the retraction indicator light 13 is still off, and the aerial work vehicle is prohibited from driving or moving. The outrigger control switch 14 should be operated to retract the outrigger rotating frame 2, and the vehicle can only drive or move after confirming that the retraction indicator light 13 is on.
[0025] Here we only introduce the outriggers with retraction detection function in the aerial work vehicle, and the other special devices of the aerial work vehicle are not introduced.
[0026] From a mechanical point of view, the outrigger fixing frame 1, the outrigger rotating frame 2 and the electric cylinder 4 form a connecting rod mechanism. When the outrigger rotating frame 2 is controlled by the electric cylinder 4 to be retracted, the detection block 8 connected to the outrigger rotating frame 2 is within the working range of the detection switch 6. In other words, whether the outrigger rotating frame 2 is retracted is judged by the distance between the detection switch 6 and the detection block 8. Therefore, when it is detected that the outrigger rotating frame 2 is in the retracted state, it can prevent the vehicle from tipping over or being damaged due to the failure to determine whether the outrigger rotating frame 2 is completely retracted.
[0027] Among them, the electric cylinder 4 is a DC push rod motor LX600 DC12V with a load of 6000N, a stroke of 200mm and a speed of 5mm / s.
[0028] The detection switch 6 is a proximity switch NBB5-18GM50-E2 from the German P+F Group.
[0029] In addition, it should be noted that the shapes and names of the parts and components of the specific embodiments described in this specification may be different, and the above content described in this specification is only an example of the structure of the utility model. All equivalent changes or simple changes made based on the structure, features and principles described in the patent concept of the utility model are included in the protection scope of the utility model patent. Technicians in the technical field of the utility model can make various modifications or supplements to the specific embodiments described or replace them in a similar manner, as long as they do not deviate from the structure of the utility model or exceed the scope defined by the claims, they should all fall within the protection scope of the utility model.
