Line ".
Underground pipe gallery is short then several kilometers, it is long then tens kilometers, piping lane internal environment there may be hazardous gas or because
Circuit damages and causes fire.Inspection is carried out inside piping lane due to only relying on patrol officer to slap completely in real-time
The operating condition of underground pipe gallery is held, therefore in order to reduce blind area, while do not roll up detection, sensing equipment, prior art again
In introduce rail mounted robot to piping lane carry out inspection in real time, while by fire resistant doorsets will be divided into inside piping lane it is multiple solely
Vertical fire compartment, the length of generally each fire compartment is 200 meters, and rail mounted robot can be arranged on the top of piping lane simultaneously
By passing through each fire compartment come the operating mode inside real-time monitoring tubular corridor.
However, existing fire resistant doorsets generally use face folding two fan electrically operated gates, the electrically operated gate on the one hand open or
It is easy to cause two fan electrically operated gates can not complete pairing because of the slideway that the foreign matter in piping lane enters electrically operated gate during closure
Or open, so as to influence the integrality for passing through and influenceing fire compartment of rail mounted robot；On the other hand this is electronic
Cost of the door in operation and maintenance is higher, and because the electrically operated gate during use when needing to open to a certain extent
Rail mounted robot can pass through, therefore rail mounted robot can have certain delay when passing through fire resistant doorsets, i.e.,
Track machine people needs a moment of pausing when reaching fire resistant doorsets, and fire resistant doorsets can just be opened, therefore reduce the inspection of track machine people
Efficiency.
In view of the shortcomings of the prior art, those skilled in the art wishes to seek a kind of fire resistant doorsets for pipe gallery,
The fire resistant doorsets can Shi Dao formulas robot effectively in real time by, and ensure the integrality of fire compartment in piping lane simultaneously, so as to
Allow the safety in piping lane is effectively monitored and ensured using its firebreak device.
