Description
Technical field
The utility model relates to a kind of traction machine brake, especially a kind of electromagnetic brake that is used for the long-range device that declutches of cage lifter towing machine band.
Background technology
At present, common elevator traction machine mostly is set in the special machine room of elevator top, when its under emergency ratings such as power failure, maintenance, in the time of can not utilizing control system to declutch automatically, availablely declutch manually, moving to make things convenient for the lift car upper lower burrs, reach the purpose of rescue and maintenance.Yet in the time of in towing machine is installed in hoistway, this mode that manually declutches is just inconvenient.For continue keeping under the emergency rating, just must be implemented in that hoistway is outer to be implemented remote manual to drg and declutch to the function that effectively manually declutches of towing machine magnet stopper.
Summary of the invention
Realize the manual difficulty that declutches in order to overcome existing electromagnetic brake outside hoistway, the utility model provides a kind of electromagnetic brake with the long-range device that declutches, and makes the operation of declutching of drg be able to realize with manual form outside hoistway.
The technical scheme that its technical matters that solves the utility model adopts is: the midway location of shell 40 is provided with one and realizes the rotating shaft 26 of hole axle normal-running fiies with shell 40 outside electromagnet 1, and end is a bronze medal bar 25 before the rotating shaft 26.When it rotates counterclockwise in the die cavity 27 that two moving iron cores are reserved, the periphery 28 and 29 of its copper bar 25 engages with the right side of moving iron core 6 and the left side of moving iron core 7 respectively, and, with the strap of the brake 22 of brake wheel 24 obvolvents and 23. rotating shafts 26 plate 30 that declutches that a usefulness fastener 36 and spindle nose are fixed is housed on the naked spindle nose electromagnet casing 40 outside separately thereby back down brake control lever 16,17 with the rotating counterclockwise and promote moving iron core of copper bar 25.The lower end of plate 30 of declutching is equipped with one and realizes the bearing pin 31 of hole axle normal-running fiies with the plate 30 that declutches.The head of bearing pin 31 has connected firmly the termination of the steel wire 32 of control wire.Two lines of centres of bearing pin 31 and rotating shaft 26 become a suitable angle [alpha] with vertical line through rotating shaft 26 centers, and another termination of steel wire 32 is passed to connect firmly behind the axis hole of control wire sleeve pipe 33 and opened a sluice gate on the handle 38.Sleeve pipe 33 passes hoistway metope hole, and its both ends of the surface are fixed on respectively between the left surface of the right flank of adapter plate 34 and metope adapter plate 35, and adapter plate 34 is fastened on the upper bracket 3 of towing machine casing 2; Adapter plate 35 is fixed on the wall face 39 of car hoistway.
The beneficial effects of the utility model are: by the long-range control wire that declutches is set on declutching plate at electromagnet, make towing machine under emergency rating, maintenance person can be readily implemented in the outer operation of declutching of hoistway, thereby successfully reaches the purpose of rescue and maintenance.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Fig. 1 is a front view of the present utility model, and long and two-short dash line is wherein partly represented the fictitious outline of towing machine, is used to show the position relation of the utility model band long-range declutch device electromagnetic brake and towing machine body.
Fig. 2 is that the A of the utility model front view is to view;
Fig. 3 is the A-A section-drawing of the utility model A on view;
Fig. 4 is the long-range scheme of installation of device on the elevator hoistways wall face that declutch of the utility model.Control wire is actual at cleaved facet D and C place to be continuous, and promptly steel wire 32, sleeve pipe 33 are continuous at this.
The specific embodiment
The utility model is mounted and fixed on electromagnet 1 on towing machine casing 2 upper bracket 3, and electromagnet 1 is made up of coil pack 4,5, moving iron core 6,7, static iron core 8,9, pilot bar 10,11, push rod 12,13, fastener 14,15 etc.; Moving iron core 6 and 7 realizes that with pilot bar 10,11 the hole axle cooperates respectively, and the interstitial hole that makes pilot bar 10,11 pass static iron core 8,9 is respectively realized the slidably cooperation of hole axle.Push rod 12 and 13 connects with pilot bar 10,11 respectively, push rod 12 and 13 can make brake control lever 16 and 17 make conter clockwise and right-hand revolution around bearing pin 18 that is fixed on casing 2 and bearing pin 19 respectively after moving iron core slide in opposition, overcome the elastic resistance of stage clip 20 and stage clip 21, thereby realize separating of the brake control lever strap of the brake 22,23 and towing machine brake wheel 24.And the right side adhesive of realization moving iron core 6 slip its left sides, back and static iron core 8, the left side adhesive of moving iron core 7 slip its right sides, back and static iron core 9.Moving the above-mentioned of iron core 6 and 7 moves in opposite directions, except being makes coil pack 4 and 5 energisings produce the result of electromagnetic force effect, also the technical scheme that can be adopted by the technical solution problem that the utility model has been explained is equipped the long-range control setup that declutches on the elevator hoistways exterior wall.
The utility model is to come work like this: when elevator traction machine is switched on, the drg magnet coil is switched on simultaneously, two groups of dynamic and static iron core adhesives respectively, push rod 12,13 make the strap of the brake 22,23 on the brake control lever 16,17 break away from brake wheel 24, towing machine normal operation respectively; When the elevator traction tester in power-down state, two push rods 12,13 will move iron core 6,7 respectively and be pushed into midway location under the pressure effect of stage clip 20,21, and the strap of the brake 22,23 obvolvent towing machine brake wheels 24 can not rotate towing machine.Be rescue or maintenance elevator, can open at hoistway exterior wall place and open a sluice gate handle 38 this moment, it is rotated counterclockwise around bearing pin 37, meanwhile, handle 38 just can drag steel wire 32, rotating shaft 26 on the plate 30 that declutches is rotated counterclockwise, the copper bar 25 of rotating shaft 26 leading portions just can back down moving iron core 6 and 7 in opposite directions with periphery 28,29, making push rod 12,13 promote brake control lever 16,17 rotates around bearing pin 18,19 respectively, make the strap of the brake 22,23 take-off the brakes wheel 24, so that the moving elevator traction machine main shaft of dish moves to desired location with car.
