The invention discloses a track state indicating unit and a crown block advancing device, the track state indicating unit comprises a dimming part, a reflecting part and a position detecting part, the position detecting part comprises a transmitting part and a receiving part which are located on the same side of the dimming part, the reflecting part is located on the side, away from the position detecting part, of the dimming part, and the dimming part has a light-transmitting state and a light-shading state. When the dimming part is in a light-transmitting state, the receiving part can receive light reflected by the reflecting part and emitted by the emitting part, and the track is in an impassable state; and when the dimming part is in a shading state, the receiving part cannot receive the light emitted by the emitting part, and the track is in a passable state. The characteristic that the light transmittance of the dimming part is adjustable is utilized, whether the position detection part can receive the light emitted by the emitting part is matched to indicate the passable and impassable states of the track, the structure is simple, maintenance is convenient, and the workload of daily maintenance can be greatly reduced.
本发明公开了一种轨道状态指示单元和天车行进装置,包括调光部、反射部和一个位置检测部,位置检测部包括位于调光部同一侧的发射部件和接收部件,反射部位于调光部远离位置检测部的一侧,其中调光部具有透光和遮光两种状态。当调光部为透光状态时,接收部件可接收经由所述反射部反射的来自所述发射部发射的光,轨道处于不可通行状态;当调光部为遮光状态时,接收部件接收不到来自发射部件发射的光,轨道处于可通行状态。利用调光部的透光率可调的特性,配合位置检测部能否接收到发射部件发出的光来指示轨道的可通行和不可通行状态,结构简单,维护方便,能大大减少日常维护的工作量。
