Description
Technical field
The present invention relates to a kind of elevator technology field, more particularly to a kind of drum-type of elevator traction machine with self-lubricating structure
Brake.
Background technology
Permanent-magnetic synchronous tractor for elevator drum brake is generally made up of electromagnet assembly and stop arm portion, electromagnet
Component is fixed on the top of motor bed-plate.Brake arm bottom is fixed on the bottom of motor bed-plate, and upper end is done by spring
Compressed with the power on push rod bolt and solenoid plunger boom end.During brake operation, in switching electricity periodic process repeatedly
In, the contact surface of push rod bolt and plunger rod has 1mm upper periodical Relative sliding, because spring and electromagnetic force are contacting
Larger normal pressure on face be present, larger frictional force can be produced when contact surface Relative sliding, after ten tens of thousands of times,
Contact surface abrasion, resulting noise can be gradually increased, and up to 65dB or so after hundreds of thousands time, caused noise is made one in electricity
Comfort in ladder declines.In order to solve the problem, a kind of improvement project is to install top cap in plunger boom end, top cap end with
Push rod bolt end is contacted, and in switching electricity periodic process repeatedly, the upper of 1mm is had in the contact surface of push rod bolt and top cap
Periodical Relative sliding, work as contact surface abrasion, resulting noise can be increased substantially, can now be incited somebody to action by elevator mainte-nance personnel
The top cap of plunger end is changed, to abate the noise and other hidden dangers.Though this mode can be eliminated by changing top cap mode
Noise, but national elevator correlation standard elevator cannot be below 2,000,000 times with brake service life, and some provincial standards will
Ask higher.
The content of the invention
Relative sliding is formed using rear push rod bolt and plunger rod for a long time present invention mainly solves brake, produces noise
The problem of, there is provided a kind of drum brake of the elevator traction machine with self-lubricating structure for reducing noise.
The technical solution adopted for the present invention to solve the technical problems is：A kind of elevator traction machine is with self-lubricating structure
Drum brake, including traction machine, electromagnet assembly, the brake assemblies with traction machine formation braking, brake assemblies include push rod
Bolt, electromagnet assembly include the plunger rod of stretching motion, and push rod bolt is withstood on plunger rod, is set on the end face of push rod bolt
The first centre bore is equipped with, second centre bore corresponding with the first centre bore, the first center are provided with the end face of plunger rod
Hole and the second centre bore are aligned, and grease is provided with the first centre bore and the second centre bore.Brake of the present invention is working
During, due to the presence of grease, frictional force is reduced between push rod bolt and plunger rod end surface, when the grease lubrication ability of end face
During decline, it can effectively be supplemented, be greatly reduced due to being made an uproar caused by friction by the grease stored in two centre bores
Sound and abrasion, the service life of brake is added, reduce the elevator safety accident thus triggered.
As a kind of preferred scheme of such scheme, the orifice position of first centre bore and the second centre bore all has
Open portion, the taper of narrow outer width is poroid in the open position.The centre bore of this programme first and the second centre bore opening are designed to
Taper is poroid, and the grease outflow being easy in centre bore is supplemented push rod bolt, plunger rod end surface.
As a kind of preferred scheme of such scheme, the orifice diameter of first centre bore and the second centre bore for 4mm ~
5mm。
As a kind of preferred scheme of such scheme, the brake assemblies also include pushing plate and the brake arm being connected,
Slide bar is provided with electromagnet assembly, pushing plate is slidably connected on slide bar, is provided with brake arm and traction machine is carried out
Dynamic watt of the braking of braking, brake includes support, and brake arm front end is hinged on the support of bottom.Brake arm one end is with pushing away in this programme
Dynamic plate is fixed, and the other end is hinged with bottom support so that braking arm configuration is more firm, is less susceptible to be formed and rocks, while also effective
The braking effect of brake assemblies is added, in braking procedure, push pedal movement drives brake arm to rotate and be close to around pin joint and draged
Draw machine, keep plate is formed with traction machine and braked.
As a kind of preferred scheme of such scheme, holding is provided with slide bar and promotes brake assemblies to be formed with traction machine
The pushing mechanism of braking, pushing mechanism include baffle plate and spring, and baffle plate setting is fixed on cunning on slide bar front end and by nut
Bar front end, spring are arranged between baffle plate and pushing plate.Elastic force principle is used in this programme, under the elastic force effect of spring, is pushed away
Dynamic pushing plate is to move inward, and keeps the braking of automatic component and traction machine.
As a kind of preferred scheme of such scheme, push rod bolt thread is connected in pushing plate, and push rod bolt front end is worn
Cross pushing plate to be in contact with plunger rod, adjusting nut is provided with push rod bolt, push rod is bolted to and pushed away by adjusting nut
On dynamic plate.This programme push rod bolt is arranged in pushing plate, when plunger rod promotes push rod bolt, drives pushing plate movement, i.e. band
Dynamic whole braking movement, carries out releasing braking.When plunger rod is retracted, brake assemblies homing, shape under pushing mechanism effect
Into braking.
As a kind of preferred scheme of such scheme, connecing for control electromagnet assembly work is provided with electromagnet assembly
Switch is touched, contact chip is provided with brake assemblies, contact chip is in contact with contact-making switch when brake assemblies are replied in place.We
Contact-making switch control electromagnet assembly work in case, when under non-brake condition, contact chip separates with contact-making switch, now holding is electric
Magnet assemblies work, and when brake assemblies are formed to the movement of traction machine side with traction machine to be braked, contact chip contacts with contact-making switch,
So that contact-making switch forms path, contact-making switch sends signal control electromagnet assembly plunger rod and stops retraction, keeps braking shape
State.Contact-making switch plays position-limiting action, limits brake assemblies movement distance, prevents brake assemblies from excessively extruding traction machine, make
Into damage.
As a kind of preferred scheme of such scheme, fixed plate is installed on electromagnet assembly, set in fixed plate
Adjustment hole, contact-making switch are arranged in fixed plate, and bolt is connected through adjustment hole with contact-making switch, contact-making switch are fixed on solid
On fixed board.This programme makes it possible to that contact-making switch installation site is adjusted, i.e., brake assemblies braking distance is adjusted.
As a kind of preferred scheme of such scheme, it is provided with plunger rod end surface corresponding with push rod bolt end face
Groove, push rod bolt end face are withstood in the groove of plunger rod end surface.This programme plays the effect spacing to push rod bolt, and it is fixed to reduce
Position bolt forms sliding in plunger rod end surface.
The beneficial effects of the invention are as follows：, can be by being store in two centre bores when the grease lubrication ability of end face declines
The grease deposited effectively is supplemented, and is greatly reduced due to noise caused by friction and abrasion, and add brake uses the longevity
Life, reduce the elevator safety accident thus triggered.
