Abstract
The utility model discloses an auxiliary brake of a mechanical friction disk. A fixed disk on the friction disk is connected with a step chain wheel driven by a main shaft into a whole through a bolt, wherein the fiction disk comprises a brake disc, a pressure disc and a fixed disc, the brake disc is positioned between the pressure disc and the fixed disc, friction sheets are arranged between the brake disc and the pressure disc and between two connecting side surfaces of the pressure disc and the fixed disc, the fixed disc and the pressure disc are pressed and matched with the brake disc, and a regulating spring is arranged on the end part of a connecting bolt of the pressure disc and the fixed disc. According to the auxiliary brake, when conditions of reversion, overspeed and broken drive chain occur, effective and stable brake is realized, and the condition that dangers to passengers are caused because of direct brake due to friction between the brake disc and the fixed disc without buffer can be avoided.
Description
Technical field
The utility model relates to the additional brake that uses on a kind of elevator, is specifically related to a kind of mechanical type friction dish additional brake of using on escalator and the moving sidewalk of being used for.
Background technology
At present, along with the increase of escalator and moving sidewalk hoisting depth, reach of the application of large foundation facilities such as Railway station, subway, harbour, airport to public traffic type escalator; Requiring all will increase additional brake; Guarantee passenger's safety, the braking in the prior art is to lean on voussoir directly to brake drive sprocket, when the link gear normal operation; The voussoir of link gear makes the driving main shaft normal operation away from drive sprocket; When link gear moved, the voussoir of link gear blocked the teeth groove of drive sprocket, makes its braking; Braking is because buffering not is prone to the passenger is caused danger like this, and directly braking causes very big destructive force to truss and the impulsive force of other parts own very Da Yi to elevator.
The utility model content
This later-model purpose is: design a kind of braking reliably, steady, overcome the friction disc that stressed unbalance loading causes and the mechanical type friction dish additional brake of the direct stuck phenomenon of main shaft.
A kind of mechanical attached brake friction dish; Reaction plate on the friction disc connects as one through the ladder sprocket wheel of bolt and main shaft drives; Wherein friction disc comprises: brake disc, platen, reaction plate, brake disc are connected brake disc and platen and reaction plate two friction lining are housed between the side between platen and reaction plate; Reaction plate and platen and brake disc force fit, the tie bolt end of platen and reaction plate is provided with regulating spring.
On the axial contact surface between brake disc and the reaction plate, the teflon packing ring is housed.
Two-layer teflon packing ring is housed on the axial contact surface between brake disc and the reaction plate.
Regulating spring is a disk spring.
The two sides of brake disc are provided with the groove of device friction lining.
Adopt this new structure; When reverse, hypervelocity, driving chain chain rupture appear in escalator and moving sidewalk; Whole ladder stops ladder and passes through the brake disc in the stuck friction disc of link gear simultaneously; Lean on friction force between brake disc and the friction lining to overcome the inertia that escalator and moving sidewalk fall to slip downwards, escalator is effectively slowly stopped.Giving under the buffering situation passenger's safety on the step that has guaranteed to drive by main shaft drives.Owing on the axial contact surface between brake disc and the reaction plate, the teflon packing ring is being housed; Lean on the wear-resisting and smooth characteristic of teflon packing ring self; Got rid of friction has relatively taken place between brake disc and the reaction plate, thereby better guaranteed only to allow to take place between brake disc and the friction lining friction relatively.Regulate because disk spring is housed, avoided stressed unbalance loading of brake disc and reaction plate stuck phenomenon.
Driving main shaft in the prior art is assemblied in truss inside through the two ends fixed block; When reverse, hypervelocity or driving chain chain rupture occurring; The link gear action, the voussoir of link gear blocks drive sprocket simultaneously, thereby glancing impact can not well guarantee the stability of elevator.And main shaft drives is the parts that drive terraced road system, and terraced road system comprises step and step chains, is to be used for conveying people.Braking on the escalator practical significance finally is the braking of main shaft drives, and the static static root in terraced road that is only of main shaft drives also is passenger's static key on terraced road.This novel good use this relation, thereby reach the purpose of braking.
The utility model structure is effective pulsation-free braking when reverse, hypervelocity, driving chain chain rupture occurring, has avoided brake disc and reaction plate that friction and the direct not buffering of braking take place, and causes danger to the passenger.

The specific embodiment
In order further to explain the technical scheme of the utility model, come the utility model is set forth in detail through specific embodiment below.
Referring to Fig. 1 and Fig. 2; A kind of mechanical attached brake friction dish; Reaction plate 6 on the friction disc 10 connects as one through the ladder sprocket wheel 11 of bolt 3 with main shaft drives; Wherein friction disc 10 comprises: brake disc 5, platen 1, reaction plate 6, brake disc 5 are connected brake disc 5 and platen 1 and reaction plate 6 two friction lining 4 are housed between the side between platen 1 and reaction plate 6; Reaction plate 6 and platen 1 and brake disc 5 force fit, platen 1 is provided with regulating spring with tie bolt 3 ends of reaction plate 6.
On the axial contact surface between brake disc 5 and the reaction plate 6, teflon packing ring 2 is housed.
On the axial contact surface between brake disc 5 and the reaction plate 6, two-layer teflon packing ring 2 can be housed.
Regulating spring on the mechanical attached brake friction dish adopts disk spring 8.
On the two sides of brake disc, be provided with the groove 12 of better device friction lining.7 is nut.
Friction lining 4 is equipped with in brake disc 5 both sides in the friction disc, and friction lining compresses through reaction plate 6 and platen 1 and brake disc 5, and thrust is regulated through the disk spring 8 of platen and reaction plate tie bolt 3 ends; Avoid brake disc 5 stressed unbalance loadings and reaction plate 6 stuck, dress teflon packing ring 2 between brake disc 5 and reaction plate 6.
As shown in Figure 3, the reaction plate 6 on the friction disc 10 is fixed as one through the bolt (not shown) with the ladder sprocket wheel 11 on the driving main shaft 9.Take a turn for the worse at escalator and moving sidewalk, when hypervelocity, driving chain chain rupture; Whole ladder stops ladder and passes through the brake disc 5 in the stuck friction disc 10 of link gear simultaneously; Brake disc 5 keeps motionless; And the reaction plate 5 in driving main shaft 9 and the friction disc 10 with platen 1 because inertia continues rotation one segment distance, lean on brake disc 5 and friction force between the friction lining 4 to overcome escalator and moving sidewalk and fall the inertia of slide downwards, escalator is effectively slowly stopped.
Product form of the foregoing description and graphic and non-limiting the utility model and style, the those of ordinary skill of any affiliated technical field all should be regarded as not breaking away from the patent category of the utility model to its suitable variation or modification of doing.
