Embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Figure 1, Figure 2, Figure 3 and Figure 4, a kind of passability track seal structure based on tunnel fire proofing door of the present invention,
Fire resistant doorsets include doorframe 1 and door leaf 2, and sealing structure includes elastic sealing device 3 and becomes rail track structure 4, is provided with door leaf 2
Horizontal straight slot, becomes rail track structure 4 and is horizontally disposed with and passes through straight slot, and elastic sealing device 3 is arranged in straight slot, and with becoming rail
4 gluing, sealing of track structure；
Becoming rail track structure 4 includes two rail rods being arranged in parallel, and rail rods include conventional aluminum pipe 5 and D types flat bar 6, D
Type flat bar 6 is located in straight slot, and the both ends of D types flat bar 6 are fixedly connected with conventional aluminum pipe 5, the arc surface of D types flat bar 6 and conventional aluminium
The upper arc surface of pipe 5 overlaps；The both ends of D types flat bar 6 are inserted into the conventional aluminum pipe 5 of 2 both sides of door leaf respectively, and pass through circle
Conical expansion pin 7 is fixedly connected with conventional aluminum pipe 5, and the depth of section of D types flat bar 6 is that 1/4, the D types of the diameter of conventional aluminum pipe 5 are flat
It is fixedly connected between bar 6 and conventional aluminum pipe 5 by stop screw.
Elastic sealing device 3 includes flexible elastomer, and two flexible elastomers fix the upper side for being fitted in straight slot respectively
With on downside, and the outer surface of two flexible elastomers keeps fitting, D types flat bar 6 is soft between two flexible elastomers
Property elastomer include it is multiple be arranged in parallel flexible semicolumn 9, multiple elasticity semicolumns 9 are with becoming that rail track structure 4 is vertical to be set
To put, the elastic inside of semicolumn 9 is hollow structure, and facing directly for elastic semicolumn 9 is fixedly connected with upper side/downside of straight slot,
Fire-proof expansion seal strip 8 is provided between elastic semicolumn 9 and straight slot.
The operation principle of passability track seal structure of the invention based on tunnel fire proofing door is as follows：
The arc surface of D types flat bar 6 and the conventional arc surface of aluminum pipe 5 are combined with the wheel of crusing robot, realize cable tunnel
Road crusing robot is stablized unimpeded by fire resistant doorsets, and the depth of section of D types flat bar 6 is about the 1/4 of 5 diameter of conventional aluminum pipe, is subtracted
Small fire resistant doorsets fluting size, at utmost ensures the fire line of original fire resistant doorsets.
Ensure the connective stability of D types flat bar 6 and conventional aluminum pipe 5 by circular cone swelling pin, while it is taper to make its exposed
Structure so that robot by during the connector of D types flat bar 6 and conventional aluminum pipe 5 by chamfered transition, to prevent joint to survey monitor
Device people's directive wheel causes to impact, so as to extend directive wheel service life, passes through spacing spiral shell between circular cone swelling pin and conventional aluminum pipe 5
Nail is fixed, and avoids D types flat bar 6 from situation about rotating occur.
Arranged because becoming rail track structure 4 into horizontal plane double track, fireproof door leaf 2 exists during being opened and closed with D types flat bar 6
Interference, interferes section to open groove, fire resistant doorsets is not interfered when being opened and closed with D types flat bar 6, then installed in straight slot in fireproof door leaf 2
Elastic sealing device 3, elastic sealing device 3 is composed by fireproof expanding sealing strips 8 and flexible elastomer are symmetrical above and below, soft
Property outer elastomeric surface in arc-shaped, inner cavity is hollow and skin friction resistance is smaller, soft beneficial to D types flat bar 6 in wherein interior movement
Property elastomer can not be stressed by compressive deformation and recoiled to original state when being squeezed.Fire-proof expansion seal strip 8 is fire-retardant, by height
Rapid expanding closure straight slot, prevents fire behavior from spreading after temperature burning.D types flat bar 6 is placed among flexible elastomer circular arc interface, D
Elastomer deformation quantity is identical up and down for 6 flexible elastomer of type flat bar, during the opening and closing of door leaf 2, D types flat bar 6 and flexible elastomer
Outer surface keeps fit-state, and fire resistant doorsets still have continuous holding one's breath property of Smoke prevention and fire line when being opened and closed at D types flat bar 6.
During fire prevention enabling is completed to shutdown whole process, because 6 contact of elastic sealing device 3 and D types flat bar is soft
Property elastomer, when it rubs with 6 contact slide of D types flat bar, contact gap very little, keep fire resistant doorsets fluting at Smoke prevention hold one's breath
Property, the fire-proof expansion seal strip 8 combined with flexible elastomer understands rapid expanding closure notch after being burnt, keeps fire prevention gate slot
Fire line at mouthful.
Elastic sealing device 3 is fixed in the straight slot of fireproof door leaf 2 by punching directly riveting, easy construction and U.S.
See.
An example for needing to open or close fire resistant doorsets is provided below：
When crusing robot detects fire point, system control fire resistant doorsets are closed, and prevent fire behavior from spreading.Transfer fire extinguishing at the same time
Robot reaches fire point, launches fire extinguisher bomb and puts out a fire.Before firefighting robot reaches fire point, fire resistant doorsets, which are in, closes
State, when system detectio to firefighting robot will be reached before fire resistant doorsets, system control firefighting robot will pass through anti-
Vent door leaf 2 is opened, and elastic sealing device 3 squeezes deformation by D types flat bar 6 at this time, and D types flat bar 6 connects with elastic mouth sealing device
Touch and slide, until door leaf 2 is opened completely.Firefighting robot has been passed through by fire resistant doorsets region, system monitoring to firefighting robot
Fire resistant doorsets, fire resistant doorsets perform shutdown action, and 3 stress of elastic sealing device squeezes deformation, until fire resistant doorsets completely close, at straight slot
By 3 sealing blocking of elastic sealing device, prevent fire behavior from spreading, firefighting robot reaches fire point, launches fire extinguisher bomb fire extinguishing.
Technical scheme is not limited to the limitation of above-mentioned specific embodiment, and every technique according to the invention scheme is done
The technology deformation gone out, each falls within protection scope of the present invention.
