Abrégé
(EN)
The invention discloses an accommodation ladder control and driving system and a method. The system comprises a power motor for driving a ladder overturning device to collect or put down an accommodation ladder through forward rotation or reverse rotation, a control valve for controlling forward rotation or reverse rotation of the power motor and provided with a control and driving loop between the control valve and the power motor, and a control valve arranged on the control and driving loop between the power motor and the control valve for controlling connection or disconnection of the control and driving loop; when the accommodation ladder is collected in place, the accommodation ladder extrudes a valve rod of the control valve, so that the control valve works to cut off the control and driving loop, and the power motor is immediately stopped working; the valve position of the control valve is changed through the accommodation ladder extruding the valve rod of the control valve in the collection in-place process; and the control valve is controlled to cut off a working medium conveying loop of the power motor, so that the power motor stops collecting of the accommodation ladder, and damage to the steel cable or accommodation ladder structure by continuous rotary tightening of the steel rope connected with the accommodation ladder through the power motor after collection in place of the accommodation ladder is prevented.

本发明公开一种舷梯控制与驱动系统及方法,包括动力马达,通过正转或反转带动翻梯装置将舷梯收起或放下;操纵阀,用于控制动力马达正转或反转,操纵阀与动力马达之间设置控制与驱动回路;控制阀,控制阀设置在动力马达与操纵阀之间的控制与驱动回路上,用于控制控制与驱动回路的通路或者断路,当舷梯收起到位时舷梯挤压控制阀的阀杆,使得控制阀工作截断控制与驱动回路,以使动力马达立即停止工作,通过收起到位过程中的舷梯挤压控制阀的阀杆改变控制阀的阀位,进而控制控制阀将动力马达的工作介质输送回路阻断,使得动力马达停止对舷梯的收起,防止动力马达在舷梯收起到位后仍继续转动收紧与舷梯连接的钢索,对钢索或舷梯的结构造成损伤。
