The invention discloses an anti-collision device and an anti-collision method for an anti-explosion crane. The anti-collision device comprises a mounting frame, a distance sensor, a magnetic repulsion piece, an anti-collision block and an anti-collision block bracket, and is mounted at the end part of a ground beam of the anti-explosion crane. The method comprises the following steps: starting a distance sensor to detect a distance, giving an alarm through an audible and visual alarm when the distance is smaller than a safe distance, and operating the crane to decelerate or stop by an operator according to a signal; if the crane is not stopped, the magnetic repulsion pieces interact to decelerate or stop the crane; and if the crane is not stopped, the anti-collision block collides and contacts to decelerate and stop the crane. By means of the arrangement, explosion caused by sparks generated in the collision process of the anti-explosion cranes can be avoided.

    本申请公开了一种防爆起重机防碰撞装置及防碰撞方法,该装置包括安装架、距离传感器、磁性排斥件、防撞块和防撞块支架,安装于防爆起重机地梁端部。该方法包括启动距离传感器检测间距,间距小于安全距离时通过声光报警器报警,操作人员根据信号操作起重机减速或停止;若未停止,则磁性排斥件相互作用使起重机减速或停止;若仍未停止,则防撞块碰撞接触使起重机减速并停止。通过上述设置,本申请能够避免防爆起重机相互碰撞过程中产生火花而引发爆炸。
