Description

Transmission mechanism of building hoist double brake power unit
Technical field
A kind of a kind of the present invention relates to transmission mechanism of building hoist, more particularly to transmission mechanism of building hoist double brake Power unit.
Background technology
Transmission mechanism of building hoist is generally using single brake power unit mode at present.This single brake power unit side Formula fairly simple convenience in structure, but there is many drawbacks:
1. security reliability is poor.Single brake power unit only has one group of electromagnetic brake, when brake is broken down, whole Individual power unit just cannot normal work:Such as there is release failure, then the output power of power unit is obstructed, and becomes running resistance Increase the reduction that mechanical load causes transmission efficiency.Long-time strap brake run, not only increase these parts additional wear and Aggravation failure, and there is difficulty in starting, electrical equipment is damaged, or even burns out restraining coil or even motor coil.Make drive mechanism not Can normal work;Such as there is brake fault, then can not need promptly and accurately to brake or position by control, scooter under the lighter, put down Layer is forbidden to cause upper and lower material difficult;Severe one mechanism and the hard land crouching bottom of cage, more impact deformation and damage, and may make Into security incident.
2. traditional single brake power unit mode fault-free detection and control protection.Because of traditional single brake power unit The electromagnetic brake band gap automatic tracking compensating device of mode, it is impossible to config failure detection and control protection.
3. running comfort is poor.Operationally because of starting loop and operation of the presence with drive mechanism for stopping deceleration Speed and live load different and there is frequently start-stop impact in various degree.The start/stop impact of building hoist is that construction rises The reason for drop machine transmission device wear-out failure, frequently most direct aggravation failure, the comfortableness of occupant is affected bigger. Single brake power unit is braked unicity because of which and lacks flexibly and effectively technical measures in terms of comfortableness is solved.
4. as building hoist is to efficient energy-saving and the development for subtracting this consumption reduction direction, two groups of power are used on market in a large number Two drive transmission devices of unit composition, because power unit is single brake structure, when arbitrary group of generation brake fault therein, then Whole drive mechanism in the case of one group of power unit cannot safe operation, even if output kinetic force meets load need in underloading Will, but demand for security cannot be met because of single braking of single group power unit;
5. because security reliability is required, traditional steel wire rope type material elevator is updated to pinion and-rack material elevator, And the single group power unit drive mechanism for bringing is commonly used, its security reliability more double brake power unit brings can not Or the needs for lacking.Accordingly, it is desirable to provide a kind of new technical scheme is solving the above problems.
Content of the invention
For solving the above problems, the present invention provide a kind of safe and reliable, comfortable, even running and can detect, applying of controlling Work lifter driving mechanism double brake power unit.
The technical solution used in the present invention is:
Transmission mechanism of building hoist double brake power unit, drives including building hoist motor special various forms of Decelerator, is provided with the shaft coupling side that install in tie-plate, the tie-plate and sets up one group of tool between the motor and decelerator There is the spring pressurization electromagnetic brake of safety protection function, the output power of the motor is through shaft coupling, with safeguard protection work( Can spring pressurization electromagnetic brake be delivered to decelerator, so as to define one drive and two separate brakes with And a deceleration device merges the power unit for constituting, i.e. double brake power unit.
When building hoist motor special drives gear reduction unit, gear reduction unit is spiral bevel gear reducer or oblique Gear reduction unit, the spring pressurization electromagnetic brake with safety protection function include electric magnet, solenoid, armature, fixation Brake disc, brake strip, special half a coupler and tripping spring, described special half a coupler one end couple motor output shaft, The special half a coupler other end couples gear reduction unit input shaft, and the gear reduction unit output shaft is equipped with output gear, The fixed brake disc is fixed in terminal pad, and the brake strip is engaged with the involute spline of special half a coupler, institute State armature and electric magnet and one suitable gap is set up by tripping spring, the solenoid is poured and is filled in electric magnet, described Between armature and fixed brake disc, the manual release handle is arranged on electric magnet back to brake strip, described special Elastomer is embedded between half a coupler and motor side half a coupler.
When building hoist motor special drives worm reducer, the spring pressurization electromagnetic system with safety protection function Dynamic device includes electric magnet, solenoid, armature, fixed brake disc, brake disc and tripping spring, and the worm reducer is defeated Enter axle to be connected with motor output shaft by shaft coupling, the fixed brake disc is fixed in terminal pad, at the brake disc Between armature and fixed brake disc, the hexagonal that the brake disc is covered with hexagonal is engaged, and the armature and electric magnet pass through A suitable gap set up by backstopping device, bonnet, adjusting sleeve and tripping spring, and the solenoid is poured and is filled in electric magnet, institute State manual release handle to be fixed on electric magnet through bonnet installed in bonnet back.
Two separate brakes are dual brake, and the dual brake includes the spring pressurization that one group of motor is carried Electromagnetic brake and add one group of spring pressurization electromagnetic brake with safety protection function or common spring pressurization electromagnetic system Dynamic device.
The spring pressurization electromagnetic brake that the motor is carried is traditional band gap automatic tracking and compensating spring pressurization electricity Magnetic brake or the spring pressurization electromagnetic brake with safety protection function.
The electromagnetic attraction that electric magnet is produced during energization overcomes spring force, the rank that will be pressed on by spring force on brake strip Ferrum sucks electric magnet, two brake linings of brake strip is unclamped with the corresponding rubbing surface of armature and fixed brake disc, power The power that motor is exported by unit starting is through motor half a coupler, elastomer, special half a coupler reducer input shaft, decelerator Internal reduction system, reducer output shaft, output gear, until building hoist(Or material elevator)On tooth bar, power Drive mechanism itself and cage is driven to carry out steady control operation up and down.
Beneficial effects of the present invention:Compared with traditional transmission mechanism of building hoist, the design of double brake power unit Structure had both solved building hoist safety problem, also improves and operates steadily and comfortableness, the design structure of this novelty Both an efficient energy-saving two drive mechanism safe universality difficult problem had effectively been cracked;Solve material elevator list simultaneously and drive driver Structure safety problem, package unit versatility are stronger, and the scope of application is big, and safe and reliable, cost is relatively low.
