Abstract
The utility model relates to a reduction device for a straight-going lift hook. The reduction device for the straight-going lift hook comprises a car, a motor, a controller, an electromagnet and a supporting plate. The motor is fixed on the supporting plate fixed on a hoistway wall; and the electromagnet is disposed below the supporting plate. The reduction device for the straight-going lift hook further comprises a permanent magnet, a wheel hub, a steel strip, a hook and a grasp ball; the permanent magnet is adsorbed on the electromagnet; the wheel hub is disposed on a motor shaft; and the steel strip is wound on the wheel hub. Consequently, a lift is prevented from speeding excessively, timely deceleration and braking are achieved, and injury to passengers is reduced.
Description
Technical field
The utility model relates to a kind of craspedodrome elevator car safety, more particularly, relates to a kind of craspedodrome elevator hook speed reduction gearing.
Background technology
In the prior art, when the craspedodrome elevator overspeed travelled, safety tongs device clamped the guide rail of car both sides under the effect that lifts of velocity limiter, and safety tongs is done cliding friction in guide rail surface, makes car finally stop to travel; When the disasteies such as earthquake occurring, car is easy to from guide rail break away from, and safety tongs can not be brought into play braking function.
The utility model content
In view of this, in order further to improve elevator safety, the utility model is a kind ofly still can be equipment or the device of elevator brake snub in operational process after safety tongs loses efficacy, thereby remedies the deficiencies in the prior art.
In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of craspedodrome elevator hook speed reduction gearing, include car, motor, controller, electromagnet and supporting plate, described motor is fixed on the supporting plate, described supporting plate is fixed on the well enclosure, described supporting plate lower position is provided with electromagnet, include permanent magnet, wheel hub, steel band, link up with and grab ball, described permanent magnet is adsorbed on the electromagnet, be provided with wheel hub on the shaft extension of described motor, described steel strip winding is on wheel hub, the upper end of steel band is fixed on the wheel hub, the lower end of steel band is fixed on the permanent magnet together with hook, and the described ball of grabbing is fixed on the car, described controller by wire respectively with motor, electromagnet is connected.
Be provided with hole on the described supporting plate, the hole that described steel band lower end is passed on the supporting plate is connected with permanent magnet.
The lower end of described steel band is provided with spring, and described spring links to each other with permanent magnet.
Beneficial effect after the employing technique scheme is: a kind of craspedodrome elevator hook speed reduction gearing, pass through the technical program, whether car moved in orbit do not require, remedy safety measure after can be used as safety tongs and losing efficacy, and can install at the higher well enclosure of floor a plurality ofly, make elevator be unlikely to hypervelocity too much, timely brake snub, increase safety, and this device in case of emergency can lift car to the position of flat bed, the realization rescue function.
Description of drawings
Fig. 1 is integral structure scheme drawing of the present utility model.
Fig. 2 is that permanent magnet separates the scheme drawing that fills under the attitude in the utility model with electromagnet.

The specific embodiment
Below in conjunction with accompanying drawing specific embodiment in the utility model is described in further detail.
As shown in Figure 1-Figure 3, the craspedodrome elevator hook speed reduction gearing that the utility model relates to, include car 1, motor 2, controller 3, electromagnet 4 and supporting plate 5, described motor 2 is fixed on the supporting plate 5, described supporting plate 5 is fixed on the well enclosure 6, described supporting plate 5 lower positions are provided with electromagnet 4, also include permanent magnet 7, wheel hub 8, steel band 9, hook 10 and grab ball 11, described permanent magnet 7 is adsorbed on the electromagnet 4, be provided with wheel hub 8 on the shaft extension of described motor 2, described steel band 9 is wrapped on the wheel hub 8, the upper end of steel band 9 is fixed on the wheel hub 8, the lower end of steel band 9 10 is fixed on the permanent magnet 7 together with hook, and the described ball 11 of grabbing is fixed on the car 1, described controller 3 by wire 12 respectively with motor 2, electromagnet 4 is connected.
Be provided with hole 13 on the described supporting plate 5, the hole 13 that described steel band 9 lower ends are passed on the supporting plate 5 is connected with permanent magnet 7.
The lower end of described steel band 9 is provided with spring 14, and described spring 14 links to each other with permanent magnet 7.
The utility model is when work, controller 3 is by wire 12 control electromagnet 4 and motors 2, motor 2 adopts permagnetic synchronous motor, controller 3 provides electric current and conversion direction of current can for the coil of electromagnet 4, but controller 3 drive motor, 2 conter clockwises or clickwise, and with motor three-phase input end short circuit, consist of the starlike attitude of envelope, permanent magnet 7 is adsorbed on the iron core of electromagnet 4, make hook 10 Bu Neng Ju to the car 1 of elevator, when controller 3 receives the hypervelocity information of speed measuring equipment, controller 3 makes magnetic pole and the corresponding permanent magnet 7 magnetic pole homopolarities of electromagnet 4 for the magnet coil of electromagnet 4 provides electric current, and under magnetic fields, hook 10 is outwards ejected, and grabbing on the ball 11 of the car 1 that hook is contained in, car 1 drives hook 10 downwards and moves down together, makes the steel band 9 that is wrapped on the wheel hub 8, motor 2 applies resistance in the reverse direction, and car 1 is slowed down.
The above only is better possible embodiments of the present utility model, is not to limit protection domain of the present utility model.
