Specific embodiment
Embodiments of the present invention is further illustrated below in conjunction with the accompanying drawings：
The above-mentioned technical problem of the present invention is mainly what is be addressed by following technical proposals：
A kind of escape device with rescue function, including outer housing 5, the outer housing 5 is internally provided with what is mutually linked
Rope sheave 2 and central rotating shaft 1,5 both sides of outer housing are equipped with actuator, and the actuator passes through the opposite list of transmission direction respectively
It is connect to transmission mechanism with central rotating shaft 1, speed-limiting device braking rope sheave 2 is additionally provided in the outer housing 5.Operating personnel's operation is outer
The actuator of 5 both sides of housing is by the positive and negative rotation of the opposite one-way driving mechanism control centre shaft 1 in direction, then passes through center
Shaft 1 and the rise and fall of the interaction relation control safety rope of rope sheave 2；The speed-limiting device can slow down 2 positive and negative rotary speed of rope sheave,
Control safety rope rise and fall speed, avoid it is too fast caused by casualties.
The speed-limiting device includes brake hubs 6, and the brake hubs 6 include the symmetrical brake block 63 of two arcs of hem type,
Described 63 one end of brake block is hinged by connector 61, and the other end is connected with each other by resetting spring 64, and forms cavity, in institute
State and deboost axle 62 be arranged in cavity, 63 outer wall of brake block connection rubs sassafras piece 65, it is described rub sassafras piece 65 and 5 inner wall of outer housing it
Between be equipped with gap, the deboost axle 62 and brake block 63 form the rotation of deboost axle 62 and drive the servo-actuated first state of brake block 63,
The second state of the 65 braking deceleration axis 62 of sassafras piece that rubs is driven with 63 rotating centrifugal of brake block.When safety rope accelerates to decline, rope sheave
Central rotating shaft 1 is driven, central rotating shaft 1 drives brake hubs 6 to rotate by gear 11 and the engagement rotation of tooth shaft 66.If under safety rope
Reduction of speed degree is faster, and 6 rotating speed of brake hubs is faster, then brake block 63 is acted on bigger by centrifugal force, and brake block 63 is more toward external expansion so that
The frictional force that the sassafras piece 65 that rubs contradicts the generation of 5 inner wall of outer housing is bigger, slows down the velocity of rotation of brake hubs 6, and then slow down safety rope
Decrease speed.
The speed-limiting device includes gear 11, and described 62 one end of deboost axle is equipped with tooth shaft 66, the gear 11 and tooth shaft 66
Form engagement cooperation so that deceleration device brakes central rotating shaft 1, and then brakes rope sheave 2.
62 other end of deboost axle is equipped with screens portion, and the screens portion forms clamping matching with brake block 63 so that subtracts
Fast axis 62 links with brake block 63；The screens portion is the extrusion of upper and lower parallel the right and left evagination, when brake block 63 by from
When mental power function is expanded outward, the inner cavity that the brake block 63 is formed slightly is expanded, but since deboost axle 62 is micro- equipped with screens portion
Rotation just resists 63 inner wall of brake block so that for brake hubs 6 in rotation process, deboost axle 62 forms screens always with brake block 63
Cooperation.
Gap is equipped between the deboost axle 62 and brake block 63, the gap is equipped with flexible fastening piece 67, flexible fastening
Part 67 can accept the conflict of screens portion, and screens portion is avoided directly to be contradicted with brake block 63 and generates abrasion, and can fix screens portion,
Deboost axle 62 is avoided to come off.
Ratchet handle 4 includes ratchet portion 41, ratchet bar 42 and handshake part 43.The actuator includes ratchet bar 42 and shakes hands
Portion 43, the handshake part 43 are equipped with anti-slip rubber or anti-skid chequer, and the anti-skidding setting of the handshake part 43 can effectively prevent operating
The working strength of personnel is then effectively lowered in error in the process, the setting of ratchet bar 42.
The one-way driving mechanism includes the ratchet portion 41 to cooperate and adapter 3, and the ratchet portion 41 is equipped with ratchet
Transmission mechanism and ratchet shaft, the ratchet mechanism include the first ratchet and pawl of external toothing cooperation, first ratchet
Internal messing cooperation is formed with ratchet shaft, the ratchet shaft brakes central rotating shaft 1 by adapter 3.Actuator movement drives ratchet
The rotation of pawl, ratchet pawl drive the one-directional rotation of ratchet shaft, ratchet shaft passes through adapter by the meshing relation with the first ratchet
3rd, the rotating of the braking rope sheave 2 of transmission successively of central rotating shaft 1, so as to control the up and down motion of safety rope.
The adapter 3, ratchet portion 41 at least one to be detachable so that this product has two kinds of escape and rescue
Pattern, if one-way driving mechanism is damaged and can also replace installation in time in use.
5 upper end of outer housing is equipped with safe hanger device 7, and the safe hanger device 7 includes safety door hook 71, the peace
Complete 71 both sides of hook are equipped with open hook 72.Safety rope can be wound opening and hung by the open hook 72 when needing emergency braking
Hook utilizes mechanics principle brake safe rope.
The outer housing 5 is equipped with control and switchs, and the control switch includes the arc groove to cooperate and movable pawl
81, the central rotating shaft 1 is equipped with the second ratchet 82, and there are two gears for control switch：First gear, the activity pawl 81 and the
Two ratchets 82 are staggered, and safety rope can freely decline rising；Second gear, movable pawl 81 are moved to 82 direction of the second ratchet, living
81 lower part of pawl is formed by gravity and the second ratchet 82 to be coordinated, then control centre's shaft 1 one-directionally rotates, central rotating shaft 1
Rope sheave 2 is engaged, and then the unidirectional of safety rope is controlled to rise mobile or stop.
Its step is,
1）When safety rope accelerates to decline, safety rope belt running rope wheel 2 accelerates rotation, and the rope sheave 2 is driven by central rotating shaft 1
Brake hubs 6 accelerate rotation；
2）The brake block 63 of the brake hubs 6 is acted on by centrifugal force to be unfolded outward, the sassafras piece 65 that rubs on the brake block 63
It resisting outer wall and generates the opposite frictional force in direction, the frictional force makes brake hubs 6 slow down, and brake hubs 6 brake central rotating shaft 1, into
And deceleration rope sheave 2 rotates, and slows down safety rope decrease speed；
3）Stir control switch, form movable 81 and second ratchet 82 of pawl and coordinate, so safety rope stop at it is specified
Position；To rise：The first actuator is rotated, central rotating shaft 1 is driven by adapter 3, the central rotating shaft 1 drives rope sheave 2
Rotation, and then safety rope is driven to rise；To decline, control switch is stirred, makes movable pawl 81 and the second ratchet 82 separate, in
Heart shaft 1 loses ratchet restraining force, and the second actuator brakes central rotating shaft 1 by adapter 3, and control safety rope declines.
The present invention has double-mode：Rescue mode and escape pattern
Rescue mode：During rescue personnel, rescuer drops to from eminence to be treated at rescue personnel, by safety rope one end safety
Hook 71, which is caught on, treats rescue personnel's safety clothes, then controls the rise and fall of safety rope by one-way driving mechanism with actuator,
If relatively near from the ground, decline using the first one-way driving mechanism control safety rope, make related personnel's safe landing；If position compared with
Height then rises to safety zone using the second transmission mechanism control safety rope.
Escape pattern：One-way driving mechanism and actuator need not be installed, present apparatus safety door hook 71 is fixed on eminence and is fixed
Point, one end clasp inherently safe clothes, and the other end holds safety rope to control decrease speed.The descent tape running rope wheel 2 of safety rope
Rotation, the rope sheave 2 drives rope sheave 2 by central rotating shaft 1, and the speed-limiting device of the connection of rope sheave 2 will limit the rotation of rope sheave 2,
And then ensure that the rotation of rope sheave 2 tends towards stability, ensure the smooth decreasing safety of personnel.
