The invention discloses a dynamic protection control method and system for hoisting equipment and the hoisting equipment. The control method comprises the steps that during traveling braking, a braking acceleration collecting system collects the whole vehicle braking acceleration generated by an electronic braking system, it is ensured that under the condition that the braking distance is permitted, the whole vehicle braking acceleration is smaller than the tipping acceleration, and the whole vehicle braking acceleration is not smaller than the tipping acceleration; therefore, the maximum driving speed allowing the equipment to operate is dynamically limited. When the speed exceeds the maximum permissible running speed, engine speed reduction, gearbox downshift and other operations are carried out, meanwhile, the braking force of the electronic brake is limited through the executing mechanism, and stable speed reduction and braking of equipment are guaranteed. According to the steering acceleration collection and control system, a steering acceleration sensor collects the steering acceleration in real time, the steering permissible rotating speed of a steering wheel is calculated, and therefore the consistency of the steering speed and the running speed of a steering axle is achieved. According to the invention, the purpose of intelligent dynamic anti-rollover of the crane can be achieved, and a good protection effect on people and objects is achieved.
一种起重设备动态防护控制方法、控制系统及起重设备,该控制方法包括:在行驶制动时,制动加速度采集系统,采集由电子刹车系统产生的整车制动加速度,确保在制动距离许可的情况下,整车制动加速度小于倾翻加速度,从而动态限制允许设备运行的最大行驶速度。当速度超过最大许可允许运行速度时进行发动机减速、变速箱降档等操作,同时也通过执行机构限制电子刹车制动力,确保设备平稳减速制动。所述转向加速度采集及控制系统,转向加速度传感器实时采集转向加速度,计算转向盘的转向许可转速,从而达到转向桥转向速度与行驶速度的一致性。本发明可实现起重机的智能动态防倾翻的目的,对人和物都具有良好的保护效果。
