Detailed description of the invention
Below in conjunction with specific embodiments and the drawings, this utility model is expanded on further.
As depicted in figs. 1 and 2, a kind of multifunctional fire-fighting person's lifesaving appliance, including the housing 1 of one end open with cover at shell
End cap 2 on body 1 opening.
Housing 1 is specially the cylindrical structural of hollow, is installed with main shaft 3 in housing 1, and described main shaft 3 is positioned at the axle of housing 1
On line, main shaft 3 is cased with escape wheel 4, bull wheel 5, wind spring 6 and ratchet 7, bull wheel 5 and ratchet 7 successively and fixes and connect, and
Rotate on main shaft 3.
In housing 1, the position of corresponding escape wheel 4 is provided with escapement lever 8, and escape wheel 4 is on a side end face of bull wheel 5
With latch 14.
Bull wheel 5 is provided with connected centrifugal block for clutch use 9 and gets rid of block spring 10, centrifugal drying near a side end face of escape wheel 4
Block 9 is arranged on bull wheel 5 especially by bearing pin, and described bearing pin is positioned at the eccentric position of centrifugal block for clutch use 9, gets rid of block spring 10 concrete
It is connected away from one end of bearing pin with centrifugal block for clutch use 9, wherein, can realize corresponding between centrifugal block for clutch use 9 and the latch 14 on escape wheel 4
Buckle.
The opposite side end face of bull wheel 5 has the concave station caved in, and described wind spring 6 is embedded in this concave station, the outer ring of wind spring 6 with
Concave station inwall fixes, and the inner ring of wind spring 6 fixes with main shaft, and described bull wheel 5 is wound with rope 11, one end of rope 11 with
Bull wheel 5 is connected, and the other end of rope 11 is free end, extend out to outside housing 1.When pulling the free end of rope 11, serving
Wheel 5 can rotate so that wind spring 6 tightens up；When decontroling the free end of rope 11, bull wheel 5 can turn round under the effect of wind spring 6,
Rope 11 is automatically retracted and is wrapped on bull wheel 5.
Here use wind spring 6, rope 11 also can be made to be in half tense situation all the time, be difficult to knotting.
When rope 11 is by rapid elongation, rope 11 can drive bull wheel 5 high speed rotating so that centrifugal block for clutch use 9 is centrifugal
Outwards throw away under the effect of power and realize corresponding buckle with the latch 14 on escape wheel 4, thus drive escape wheel 4 to rotate, and escapement
Wheel 4 can do retarded motion under the effect of escapement lever 8, so that reduce the speed that rope 11 is drawn out.
In housing 1, the position of corresponding ratchet 7 is provided with ratchet 12, and ratchet 12 is arranged in housing 1 by bearing pin, described pin
Axle is through the center of ratchet 12, the multifunctional button 13 being arranged above extending out to outside housing 1 of ratchet 12, ratchet 12 and ratchet
One end that 7 contact connects ratchet spring 15 so that ratchet 12 is close to ratchet 7 direction and supports to ratchet space, simultaneously
One end that ratchet 12 contacts with ratchet 7 is more than the other end, and the tip that the relative direction with past ratchet 7 crown protrudes out.
Here ratchet spring 15 can be stage clip or extension spring.
Effect due to ratchet spring 15 so that the head of ratchet 12 is close to ratchet 7 all the time；When multifunctional button 13 supports
When being connected to the cental axial position of ratchet 12, this multifunctional button 13 is inoperative to ratchet 12, and ratchet 12 is at ratchet spring 15
Effect is lower touches with ratchet 7 so that ratchet 7 can only flick ratchet 12 along single direction and rotate；When mobile multifunctional button
During the stub end that 13 are connected to ratchet 12, the tip of ratchet 12 and ratchet 7 abut against and cannot on lift so that ratchet 7 cannot revolve
Turn, it is achieved the locking of the length of rope 11；When mobile multifunctional button 13 is connected to the little head end of ratchet 12, the point of ratchet 12
Being lifted away from ratchet 7 in portion, now ratchet 7 can free bidirectional rotation.
During use, this device is hung on fire-fighting belt, and according to on-site actual situations before operation, the free end of rope is hung on jail
On the fixture leaned on, fireman can in cord range evolutionary operation.Due to the existence of wind spring, rope can be with the movement of fireman
It is elongated or automatically shortens, and rope is in half tense situation all the time, being difficult to knotting.
When fireman drops out outside building owing to flashing over impact, or owing to hiding high temperature roaring flame, toxic smog, partly collapsing
When needing urgent danger prevention to jump out outside building, rope can be elongated, drive bull wheel high speed rotating so that centrifugal block for clutch use from
Thrown away under mental power function and realized buckle with the latch of escape wheel, and then driving escape wheel to rotate, and due to the work of escapement lever
With, escape wheel can make retarded motion, makes fireman carry out slow fall, and now, fireman can make next step action according to practical situation.
When, in ongoing operations, needing the length of stationary rope to limit working range, can be pulled to the rope in this device need
After wanting length, stir multifunctional button, make the rope lengths of pull-out be locked, use as fixed length protection rope.
When climbing operation, multifunctional button can be placed in centre position, while climbing, this device automatically retracts rope
And monodirectional locking, on the one hand can be in operation under level altitude, even if another aspect climbing being accidentally dropped slippage, due to this dress
Put instant locking do not result in yet fall injured.
