Vehicle body and aerial work platform with reversible control box

【Technical field】

The utility model relates to the field of engineering machinery, in particular to an engineering operation vehicle, and more particularly to a vehicle body and an aerial work platform with a reversible control box.

【Background technique】

Aerial work platform is an advanced aerial work machine, which can greatly improve the work efficiency, safety and comfort of aerial construction personnel, and reduce labor intensity. It has been widely used in developed countries. The use of aerial work platforms in my country is becoming more and more extensive, such as the initial general municipal street lamp maintenance, garden tree pruning, etc., and with the rapid development of my country's economy, engineering construction, industrial installation, equipment maintenance, plant maintenance, shipbuilding, Electricity, municipal administration, airports, communications, gardens, transportation, etc. have a growing demand for aerial work platforms.

The control device of the traditional aerial work platform is generally installed on the operating platform or/and in the cab of the vehicle body. The former control method is that the worker stands on the operating platform and controls the lifting of the operating platform and other operating actions through the control device. , the worker and the control device move together with the operation platform, for example, it is raised or lowered together with the operation platform. It cannot control the aerial work platform on the ground, and the worker must control the aerial work platform on the operation platform. Its operation is very inconvenient; and the latter control method is that the worker controls the lifting or other operation actions of the console through the control device in the cab. Since the worker must be in the cab, the cab is generally a closed space or a semi-closed space. It will cause certain obstacles to the worker's sight or have a certain blind spot, so that the aerial work vehicle cannot be controlled more accurately to make corresponding actions. To achieve the preset control purpose, it is often necessary to repeatedly control the aerial work platform to perform the same action, for example, Moving the console to a certain height may require repeated maneuvers to raise and lower the console, and may also require the worker to frequently stick his head out of the cab to check the height of the console or another worker outside the cab to assist with command , therefore, the effect achieved by its related manipulation is relatively poor, and its limitation is large, and the manipulation is very inconvenient.

Of course, with the development of society and the continuous advancement of technology, there are currently some boom-type aerial work platforms that are fixed on the side of the turntable of the car body with a control device that is convenient for workers to stand on the ground to perform manipulation. If it is arranged on the turntable, it will rotate with the rotation of the turntable, and the worker will also adjust the standing position along with the rotation of the turntable when manipulating it, which also has many inconveniences.

And the above-mentioned control methods all fix the control device at the corresponding position. When the control device is in an idle state, it cannot be stored and hidden. Therefore, not only the control device cannot be well protected, it is easy to reduce dust and aging, and the Said control device also can occupy certain space of relevant area when idle, and then causes great inconvenience to worker's work and influences attractive in appearance.
