Description
Technical field
Level crossing facility technology field is the utility model is related to, the emergent automatic receipts in specifically a kind of Scroll road junction
Contracting protection band structure.
Background technology
At present, in electronic door, the electric railing of blocking of crossing equipment because power-off fault causes to be unable to normal use, again without timely
Repair or in train unexpected power-off fault when coming, Emergency use is rope, uses very inconvenient, blocks and stops vision
Effect bad especially night is less obvious, easily causes vehicle and swarms into accident occurs in road junction, causes road junction life safety and row
The great potential safety hazard of car security presence.
Utility model content
The purpose of this utility model is that providing a kind of emergent automatic shrink in Scroll road junction protects band structure, for solving
Electronic door, the electric railing of blocking of crossing equipment easily causes vehicle and swarms into generation in road junction because power-off fault causes to be unable to normal use
Accident, road junction life safety and traffic safety is caused the problem of great potential safety hazard to be present.
The technical scheme in the invention for solving the technical problem is：Emergent automatic shrink in Scroll road junction is protected
Band structure, for the automatic contraction of cable, it is characterized in that, including reel, the clockwork spring being fixed on by fixing axle between the housing of left and right
Wind spring and self-locking detent；Fixed seat is provided with the middle part of the housing of left and right；Reel is respectively equipped with the both sides of reel；Clockwork spring wind spring
The left side of fixing axle is arranged on, is mutually fixed by fixed seat with left shell；Self-locking detent, self-locking are provided with right hand fixed seat
Ratchet is connected by return spring with fixed seat；Arc inner tooth, self-locking are provided with the corresponding reel in self-locking detent tip
Ratchet tip is engaged with arc inner tooth.
Further, one end of buffer zone is fixed in fixing axle, draw ring is provided with the end of buffer zone, in draw ring
Stop block is provided with the buffer zone of inner side.
Further, the front end of housing is provided with handle.
The beneficial effects of the utility model are：
1st, the emergent automatic contraction buffer zone in Scroll road junction can play to road junction blocks door, railing equivalent effect, effectively anti-
Only pedestrian, vehicle swarm into road junction, to Crossroad attendant, operate flexible and convenient.To maintenance personal, paint to cover without antirust and protect
Shield, reduce maintenance labor intensity and maintenance costs.
2nd, have the advantages that simple in construction, safe and reliable, service life is long and easy to install.
3rd, the emergent automatic buffer zone that shrinks in Scroll road junction has pull-out smooth-going, does not beat strand function, and automatic retracted for clearance.
The device is general for all types level crossing, and different size of road junction need to only adjust the length of buffer zone, general
Property good, simple installation, completely adapt to varying environment road junction use.

Embodiment
Emergent automatic shrink in Scroll road junction protects band structure, is related to a kind of wrap-up of buffer zone or cable, can be certainly
Dynamic retraction, the device can to road junction train near when play and block the equivalent effect of door, railing, prevent pedestrian, vehicle from passing through
Mouthful；And safety protection function can be effectively played to road junction pedestrian, vehicle.
As shown in Figures 1 to 6, including by fixing axle 5 reel 9, the clockwork spring being fixed between left shell 11 and right shell body 12
Wind spring 51 and self-locking detent 6；Fixed seat 3 is provided with the middle part of the housing of left and right；Reel 7 is respectively equipped with the both sides of reel 9；Hair
Bar wind spring 51 is arranged on the left side of fixing axle 5, is fixed with left shell 11 by the phase of fixed seat 3；It is provided with right hand fixed seat
Self-locking detent 6, self-locking detent 6 are connected by return spring 61 with fixed seat 3；In the sophisticated corresponding reel 9 of self-locking detent 6
On be provided with arc inner tooth 8.Self-locking detent tip is engaged with arc inner tooth, when buffer zone is extracted out, can keep buffer zone
Length it is constant.
One end of buffer zone 4 is fixed in fixing axle 3, and draw ring 42 is provided with the end of buffer zone 4, for protecting
Fixed protection band when band pulls out, is provided with stop block 41, stop block can stop that buffer zone is rolled up completely on the buffer zone on the inside of draw ring
Enter shell, so that next time is continuing with.
Be provided with handle 2 in the front end of housing, handle can fix use, can also hand take and use.
Self-locking detent and arc inner tooth are engaged, and realize auto-lock function, after one section of buffer zone is pulled out, self-locking detent and arc
Shape internal tooth works, and keeps the pull-out length of buffer zone constant.When buffer zone needs to retract, one section of protection need to be pulled out again
Band, buffer zone cross arc inner tooth, and hand gently firmly retract band automatically by buffer zone, buffer zone.During the pull-out of buffer zone, volume
Cylinder rotation, when self-locking detent is with the arc inner tooth to reel, hand is unclamped, self-locking detent blocks reel and causes buffer zone to keep lock
Only state, it is impossible to reclaim, when needing recovery, pull outward buffer zone, makes ratchet cross the arc inner tooth of reel, at this moment exists
Under the driving of internal clockwork spring wind spring, buffer zone reclaims automatically.
Correspondingly, buffer zone of the present utility model can be changed to electric wire or tracheae etc., and equivalent effect can be achieved.
Described above, simply explained through diagrams some principles of the present utility model, and this specification is not intended to this practicality
It is new to be confined in described concrete structure and the scope of application, therefore every corresponding modification for being possible to be utilized and equivalent
Thing, belong to the apllied the scope of the claims of the utility model.
