A fire truck boom vibration control device, method, system and fire truck

Abstract

The invention discloses a fire fighting truck cantilever crane vibration control device, method and system and a fire fighting truck. The control device comprises a receiving device and a control device, wherein the receiving device is used for receiving the cantilever crane length, cantilever crane loads and cantilever crane dip angles, and the control device is used for obtaining the cantilever crane vibration frequency according to the cantilever crane length, the cantilever crane loads and the corresponding relation among the cantilever crane length and the cantilever crane loads and the vibration frequency, obtaining the accelerated speed according to the cantilever crane loads, controlling the movement of an amplitude variation oil cylinder according to the cantilever crane vibration frequency, the accelerated speed and the cantilever crane dip angles, and accordingly absorbing vibration of a fire fighting truck cantilever crane. According to the fire fighting truck cantilever crane vibration control device, method and system and the fire fighting truck, various detection devices in the fire fighting truck can be sufficiently used, and the vibration under various working conditions can be absorbed.

Description

technical field [0001] The invention relates to a fire truck, in particular to a vibration control device, method and system for a fire truck boom and a fire truck. Background technique [0002] Boom-type construction machinery will vibrate during operation, especially for construction machinery such as aerial ladder fire trucks. Due to the long boom and high flexibility of aerial ladder fire trucks, the vibration amplitude is also large during operation. In order to reduce the vibration of the aerial ladder fire truck, the operator's skills are generally used to reduce the vibration, but this solution is very unsafe, because in an emergency, the operator may be nervous due to the situation on the spot, resulting in a large Amplitude of jib vibration. [0003] There are also some vibration control schemes in the prior art, such as the vibration control scheme of the pump truck system, but these control schemes are not suitable for engineering machinery such as aerial ladder...

Problems solved by technology

In order to reduce the vibration of the aerial ladder fire truck, the operator's skills are generally used to reduce the vibration, but this solution is very unsafe, because in an emergency, the operator may be nervous due to the situation on the spot, resulting in a large Amplitude of boom vibration

[0003] There are also some vibration control schemes in the prior art, such as the vibration control scheme of the pump truck system, but these control schemes are not suitable for engineering machinery such as aerial ladder fire trucks, and these control schemes only control vibration for a single working condition and cannot meet real needs
