Control lever safety apparatus for heavy equipment

本发明涉及一种用于重型设备的控制操纵杆安全设备，该设备在启动所述设备的状态下操纵或触动控制杆时，能够在使安装在驾驶座侧表面的控制箱倾斜的情况下、以使安全杆沿下降方向倾斜的方式，防止工作设备动作。本发明的设备设有：一根安全杆和控制箱斜度调节杆，它们可转动地固定至第一支承件上，在该支承件上固定有驾驶室入口门一侧的控制箱；一操作开关组件，其以连杆运动方式与控制箱斜度调节杆相连并且在转动控制箱斜度调节杆时使安全杆以下降方向倾斜，从而切断与控制杆相连的电源；以及一闩锁组件，该组件以连杆运动方式与操作开关组件相连，并在控制箱斜度调节杆转动时使控制箱向上倾斜，从而切断与控制杆相连的电源。 A control lever safety apparatus for a heavy equipment which is capable of preventing an operation of a work apparatus when a control lever is operated or touched in a state that an equipment is started, in such a manner that a safety lever is tilted in a lower direction in the case that a consol box installed in a side surface of a driver's seat is tilted. There are provided a safety lever and consol box tilting lever which are rotatably fixed to a first support in which a consol box of a side f an entrance door of a driving room is fixed, an operation switch assembly which is connected with the consol box tilting lever based on a link movement method and supports the safety lever in a horizontal direction and tilts the safety lever in a lower direction when the consol box tilting lever is rotated for thereby disconnecting a power connected with the control lever, and a latch assembly which is connected with the operation switch assembly based on a link movement method and tilts the consol box in an upper direction when the consol box tilting lever is rotated for thereby disconnecting a power connected with the control lever.
