A kind of aerial work platform control method and aerial work platform

Abstract

The invention relates to the technical field of aerial work platforms, in particular to a control method for aerial work platforms and an aerial work platform. The method includes the following steps: obtaining a working instruction of the leg expansion cylinder; controlling the expansion and contraction of the leg expansion cylinder; when the expansion leg expansion cylinder reaches the preset leg expansion cylinder expansion and contraction amount, the leg expansion cylinder stops working; and the operation platform rises. The method provided by the present invention controls the expansion and contraction amount of the leg expansion cylinder according to the actual working conditions of the aerial work platform. In addition, the method can also control the expansion and contraction of the leg expansion cylinder according to the desired height, which is different from the outrigger in the prior art. Compared with the operation after fully unfolding, this control method does not need to fully expand the outriggers and then raise the working platform, which can be suitable for the needs of different working conditions, which can save the operation time, improve the operation speed, and reduce the energy consumption at the same time. loss.

Description

technical field [0001] The invention relates to the technical field of aerial work platforms, in particular to a control method for aerial work platforms and an aerial work platform. Background technique [0002] The chassis of the aerial work platform is responsible for the walking and steering of the whole vehicle. Due to the length and width restrictions of the road surface and transportation vehicles, the chassis needs to limit the total width of the chassis in the non-operating state or transportation state; but in the operating state, the chassis needs to be enlarged. The span of the tires ensures the stability of the whole vehicle during the operation and avoids tipping. Generally, two methods of telescopic axles or X-shaped expansion legs are used to increase the stability of the working state. The retractable and expanded legs of the high-meter lifting work platform are all one. The oil cylinder controls one outrigger, and the retraction and expansion speed of each ...

Problems solved by technology

[0002] The chassis of the aerial work platform is responsible for the walking and steering of the whole vehicle. Due to the limitation of the length and width of the road and transport vehicles, the total width of the chassis needs to be limited in the non-working state or in the transportation state; but in the working state, the chassis needs to be enlarged. The span of the tire ensures the stability of the whole vehicle during the operation and avoids tipping. Generally, two methods of telescopic axle or X-shaped expanding legs are used to increase the stability of the working state. The retracting and expanding legs of the high-meter-number lifting operation platform are all one The oil cylinder controls one outrigger, and the retraction and expansion speed of each outrigger is determined by the tire friction force. The hydraulic system cannot control the synchronous retraction and expansion of the outriggers.

For existing mature products, the working position of the outriggers of the X-type chassis is jointly determined by the angle sensor and the limit sensor. The work can only be carried out after the outriggers are fully expanded, resulting in slow operation speed and energy consumption.
