The invention discloses a safety control system and control method for an insulated overhead working truck, and belongs to the field of engineering machinery. The getting-off supporting leg control comprises a hydraulic pump, a locking getting-on electric control valve, a locking supporting leg electric control valve, a left supporting leg control valve set, a right supporting leg control valve set, a supporting leg oil cylinder, a hydraulic lock and a travel switch, and the getting-on arm support control comprises arm support rotary table control and arm support platform control. The device is easy to control, safe and reliable, and automatic interlocking safety protection is carried out on the supporting leg and the arm frame when a worker of the overhead working truck carries out live-line work; all actions of the rotary table auxiliary operation arm support are controlled through two-hand enabling, and a platform main operation arm support is subjected to enabling operation through a composite insulation handle in an active mode and is subjected to enabling operation through a self-locking handle in a non-active mode through a single hand. Leveling response is automatically carried out, an alarm sound is automatically given out when the landing leg of the vehicle is operated, a worker is safely put back to the ground when an electric control system has an accident, and the practical value is very high.
本发明公开了一种绝缘高空作业车安全控制系统及控制方法,属于工程机械领域,包括下车支腿控制和上车臂架控制;下车支腿控制包括液压泵、锁上车电控阀、锁支腿电控阀、左支腿控制阀组、右支腿控制阀组、支腿油缸、液压锁、行程开关,上车臂架控制包括有臂架转台控制和臂架平台控制。本发明控制简单、安全可靠,在高空作业车工作人员带电作业时,进行支腿与臂架自动互锁安全保护,使用双手使能控制转台辅助操作臂架各动作、使用单手对平台主操作臂架主动作采用复合绝缘手柄的使能操作和非主动作采用自锁手柄的使能操作,自动进行调平响应并在下车支腿操作时自动发出警报声响、在电控系统意外时将工作人员安全放回地面,具有非常高的实用价值。
