Kind.
The content of the invention
The technical issues of present invention need to solve is reliable and stable and quiet deceleration, elevator speed when elevator is out of control
Normal running speed is restored to, now provides a kind of novel elevator safe retarder, specifically includes elevator safety trigger and deceleration
Device, elevator safety trigger is by weight, spring, brake switch, alarm switch, device, the arc for fixing brake cable crust mouth
Shape plate and brake cable composition, deceleration device work as accident by being made of the guide rail of toothed surfaces, gear, brake, brake cable and bearing
（Upper punching or tenesmus）During generation, super normal range (NR) moves to open brake switch weight under the action of the spring, by there is dentation
Guide rail, gear and the brake in face are decelerated to normal running speed, and without huge metal friction sound.
Description of the drawings
Fig. 1 is elevator safety trigger of the present invention and deceleration device overall structure figure
Fig. 2 is brake switch texture edge figure of the present invention
Fig. 3 is deceleration device texture edge figure of the present invention.
Specific embodiment
1 as shown in Figure 1, 2, 3, elevator safety retarder, specifically includes elevator safety trigger and deceleration device, elevator peace
Full trigger is by spring 1, weight 2, brake switch 3, alarm switch 4, device 13, the arc panel for fixing brake cable crust mouth
14 and brake cable 6 form, deceleration device is by having 10 groups of the guide rail 12 of toothed surfaces, gear 9, brake 11, brake cable 6 and bearing
Into,
2 respectively install one or two elevator safety trigger in cab top and bottom, in the right flank of elevator safety trigger
Spring 1 at point is installed, weight 2 is connected in 1 other end of spring, arc panel 14, arc panel 14 and front-back are installed in front-back
Arc area is formed, weight 2 does arc up and down motion under the action of spring 1 in the arc area, the water at left surface midpoint
The symmetrical each three blocks of plates of self installation in the both sides of plane, this three blocks of plates are spaced apart, from outside to inside, first piece installed in A, F point
Plate, first piece of plate free-end installation alarm switch 4, installs second block of plate, second block of plate is that brake switch 3 is fixed in B, E point
Plate installs the 3rd block of plate, the device 13 of the 3rd piece of fixed brake cable crust mouth of plate free-end installation, wherein brake is opened in C, D point
It is most short in three blocks of plates to close 3 fixed plates, brake switch 3 is made of movable plate, fixed plate and two brake switch springs 5, movable plate
It is linked together with fixed plate by movable axis, 6 interior lines of brake cable are connected on movable plate, the connection of 5 one end of brake switch spring
In left surface and fixed plate junction B, E point, the other end is connected on movable plate, and 6 interior lines of brake cable are connected on movable plate
Position is the midpoint with the position for being connected brake switch spring 5 in movable axis, and movable plate free-end can be in 14 edge of arc panel
The regional movement at alarm switch 4, during elevator normal operating condition, weight 2 is under the action of spring 1 in normal range (NR) JK
Interior movement, movable plate free-end rest on 14 edge of arc panel under the action of brake switch spring 5, at 6 interior lines of brake cable
In relaxation state, brake gear is closed, and alarm is closed, and when elevator is in upper punching or tenesmus, weight 2 is in the effect of spring 1
It is moved beyond normal range (NR) JK down, hits movable plate free-end and away from stop place, movable plate free-end is opened in brake
It under the action of closing spring 5, is rested on after movement at alarm switch 4,6 interior lines of brake cable are tightened up, and brake gear starts, alert
Device is reported to start, alarm alarm, warning lamp flickers, and the brake switch activity Board position 8 after brake is shown in effect demonstration,
The nearly cab face of 3 two guide rails is dentation, and brake cable 6 is connected on brake 11, per side at cab top and bottom level gauge
Respectively one deceleration device of installation, the gear 9 and brake 11 of deceleration device are fixed on bearing 10, and bearing 10 is fixedly mounted on electricity
At terraced top and bottom level gauge, the guide rail 12 and gear 9 that have toothed surfaces are combined together by dentalation, when brake gear is closed
When, 6 interior lines of brake cable are in relaxation state, and gear 9 drives brake 11 on having the guide rail 12 of toothed surfaces and by bearing 10
Idle running, plays a part of stable cab, and when brake gear starts, 6 interior lines of brake cable are tightened up, and brake 11 starts to brake,
