Abstract
A kind ofly be used for elevator drive, especially for the fail-safe brake of the elevator of manned or loading, be that the inside shoe brake by Electromechanical Control constitutes.At driving wheel (1) or be used to drive in the roller bearing end cap of motor of driving wheel and be provided with two brake shoe brake cheek.By electromagnet (4,5) brake shoe brake cheek (3) is remained on the control position, wherein parts of yoke (5) double as elevator roller bearing end cap.When outage, the stage clip (7) that is arranged between an attachment point (6) and the brake shoe brake cheek (3) is pressed to brake shoe brake cheek on the interior braking driving surface of driving wheel (1) or roller bearing end cap.
Description
The present invention relates to a kind of elevator drive that is used to have a driving wheel, especially for the fail-safe brake of the elevator of manned or loading.
The drg that is generally used for elevator drive is in brake shoe brake cheek by pull bar or leverage.The shortcoming of the drg of this class pattern is that scantling of structure is big and maintenance cost is higher.
Task of the present invention is to provide a kind of fail-safe brake that is used to have the elevator drive of a driving wheel, it can reduce scantling of structure and reduce parts, thereby reduce the consumption of the work-hours of making elevator drive, improved the reliability of drg simultaneously again.
Fail-safe brake of the present invention has following feature: this drg is Electromechanical Control and inside shoe brake that have a brake shoe brake cheek at least, this brake shoe brake cheek has two ends, the one end is installed on the hinged point of a stationkeeping of (or in roller bearing end cap of the electrical motor of driving driving wheel) in the driving wheel, and the other end of brake shoe brake cheek places a fixed pivot place in the driving wheel.At least be equipped with two stage clips between the other end of attachment point and described brake shoe brake cheek, stage clip is pressed to brake shoe brake cheek on the interior braking driving surface of driving wheel (or end cap of the electrical motor of driving driving wheel).Brake shoe brake cheek is positioned at the work area of the electromagnet of driving wheel; Electromagnet is resisted a stage clip at least, and its mode of action is that electromagnet overcomes the pressure of spring when energising, and brake shoe brake cheek and braking driving surface are thrown off.As long as alive in the electromagnet, then this brake shoe brake cheek just remains on this control position.
The preferred plan of fail-safe brake of the present invention is embodied in the feature of dependent claims.
The magnetic pole of electromagnet preferably adopts annular magnetic pole.
This electromagnet preferably also comprises a yoke (5), and this yoke can be used as the parts of elevator, preferably as one-sided roller bearing end cap.
This yoke should adopt annular, and places between the magnetic pole of electromagnet, and the slow u type groove of putting down and be shaped on is made at its edge.By making the slow flat magnetic resistance that can improve in edge at the magnetic circuit in magnetic disturbance district.U type groove then is used to place the annular magnetic pole of electromagnet.The most handy flat board of this magnetic pole is located and is covered fully by this flat board.
At an other compensating pole, the directional magnetic field of formation magnetic pole of also can making of this magnetic pole.It can compensate the magnetic flow in the machine (as bearing).Compensating pole can be connected in series with magnetic pole.But the coupling between magnetic pole and the compensating pole also can adopt other form.
Fail-safe brake of the present invention can also be made two shoe brake, and wherein two brake shoe brake cheek are arranged on the inside of driving wheel symmetrically.Two brake shoe brake cheek can be arranged in the work area of same electromagnet and can be supported on same fixed point by spring.
Also a plurality of brake shoe brake cheek can be set in the driving wheel, wherein each brake shoe brake cheek all disposes magnetic pole (4) separately.
The substantial advantage of technical solution of the present invention is removed and is reduced scantling of structure, braking procedure has maximum reliability when saving pull bar or lever and also can guarantee to cut off the power supply outward, its drg should be designed to, no matter a plurality of brake shoe brake cheek are arranged still is that a brake shoe brake cheek can both guarantee that whole elevator reliably brakes, so become fail-safe brake.
Below will by one as shown in drawings embodiment further describe the present invention.Description of drawings is as follows:
Accompanying drawing 1 is the front elevation of an elevator drive, and the interior shoe type fail-safe brake of an Electromechanical Control is wherein arranged, and there is a part sectional view at the place at principal and subordinate's wheel, is used to represent an electromagnetic pole and compensating pole of described drg;
Accompanying drawing 2 is the lateral plan of the inside shoe brake embodiment of an Electromechanical Control, and drg is a two shoe brake among this embodiment.
Elevator drive shown in Figure 1 mainly is made up of an electrical motor 12, a driving wheel 1 and a drg.This drg has common, a fixing and torsion-shaft 13 not.Electrical motor 12 is external rotor electric machines, and driving wheel 1 is directly installed on the flange of motor armature.Two hinged points 2 that are used to support the brake shoe brake cheek 3 of drg are positioned at driving wheel.An electromagnet that is made of annular magnetic pole 4 is fixed on the yoke 5, but the roller bearing end cap parts of yoke double as elevator drive.The design of electromagnet should guarantee, thereby the pressure that can overcome the stage clip 7 that is fixed on the fixed pivot 6 when energising is inhaled moving brake shoe brake cheek 3.Stage clip 7 is pressed to brake shoe brake cheek 3 on the braking driving surface in the driving wheel 1 during outage.Driving wheel is as the braking hub.The yoke 5 of annular is between magnetic pole 4, and its edge is made into to delay flat and is shaped on u connected in star 8, is used to settle electromagnetic pole 4.Electromagnetic pole 4 usefulness, one dull and stereotyped 9 location are also covered fully.Be provided with a compensating pole 10 on magnetic pole 4 sides, itself and this magnetic pole is connected in series.Compensating pole 10 forms the directed compensating field of electromagnetic pole 4.
