Abstract
The present invention relates to a toothless dragger in a frame structure, which comprises a base, a motor, a brake, a dragging wheel and a coder, wherein the base is in a cube shape and in a frame structure; the top surface, the bottom surface, the front mounting surface and the rear mounting surface of the base are respectively provided with mounting holes. The centre of one end face of the base provided with the dragging wheel is provided with an inward wide groove, so that the dragging wheel and a dragging rope are both in the base. A motor stator is pressed and sheathed in the base. A rotor outside the circumference surface of the stator is pressed and sheathed in a rotor bracket and is tightly matched with the rotor bracket. A friction plate on the end face of the armature of the brake corresponds to the rotor bracket in the base. When power failure happens, a compression spring in the brake drives the friction plate on the end face of the armature to press the outer rim of the rotor bracket so as to brake the dragging wheel. The toothless dragger has flexible and various mounting forms and uses the rotor bracket as a braking wheel. The braking wheel and the dragging wheel are both arranged in the base, so that the axial dimension of the dragger is reduced so as to satisfy requirements of the dragger without a machine room.
Description
Technical field
The present invention relates to Toothless dragger in frame structure and installation method thereof that a kind of cage lifter car is used, belong to a kind of elevator accessory and its installation method.
Background technology
The anodontia towing machine of existing no machine room (comprising small room), its mounting means all is to adopt two kinds of wall-hanging (comprising that guide rail clamps formula) and footing installing types (comprising footing suspension type up), each anodontia towing machine is because of the restriction of structure, can only adopt a kind of mounting means, so the user can't require to select mounting means according to the difference that elevator hoistways is arranged versatile and flexiblely.Moreover, the anodontia towing machine of this traditional employing outer-rotor structure, its traction sheave is to be suspended from outside the support, so support intensity is had relatively high expectations relatively.And its brake wheel also is to be suspended from outside the support, so its axial dimension is bigger, and is short and small to dimensional characteristic to the anodontia machine shaft of no machine room, brought difficulty and unfavorable.
Summary of the invention
The objective of the invention is to defective and deficiency at prior art, to design a kind of installation form versatile and flexible for elevator industry, and the short and small a kind of Toothless dragger in frame structure of axial dimension.This anodontia towing machine comprises support, motor, drg, traction sheave and coder, and wherein support is that frame-type is cube shaped.On end face, bottom surface and the front and rear end of support, have mounting hole; The support end face (front end face) that towing machine one end is installed has the indent sipes, and traction sheave and hoist ropes are in the support; Described motor is a permagnetic synchronous motor, and the stator gland in the motor is in the outer rotor gland of stator circumference face in rotor field spider in support, and with the rotor field spider flush fit; Support is equipped with drg on left and right two side end faces, and the armature upper friction plate in the drg is corresponding with the rotor field spider wheel rim, and during outage, the friction lining on the armature is tight against rotor field spider wheel rim (used as braking wheel) stops car or the braking deceleration operation.Toothless dragger in frame structure of the present invention is with the support of cube shaped framework as towing machine, and on the top of support, the end, forward and backward four attachment faces, have mounting hole, towing machine can be faced, leans against the hoistway metope installs, also towing machine end face or bottom surface can be contained on the end face or support of hoistway, this towing machine can also be installed on the pit of hoistway.Can according to the arrangement requirement of user's elevator hoistways, select the wherein a kind of of five kinds of mounting meanss neatly arbitrarily with same anodontia towing machine.Realized versatile and flexibleization of mounting means.The brake wheel of the drg of this towing machine is replaced by the wheel rim of the rotor field spider in the support, simplifies the structure, and can shorten the axial length of anodontia towing machine greatly, and work preferably does not have the machine room mode and installs and uses.Moreover, adopt traction sheave to be installed in the indent sipes of support end face, strengthened the intensity of support, can satisfy under the condition that same load requires, make this anodontia towing machine make lightlyer.

The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, in the support 4 permagnetic synchronous motor is housed, stator core 11 glands that are embedded with coil on support, and with the support flush fit, form stator.Rotor core 12 glands of embedded permanent magnet in rotor field spider 13, and with the rotor field spider flush fit, constitute rotor.Rotor field spider 9 is supported in the centre hole of support 4 by bearing 10 and 14.When stator coil was supplied with three phase mains by frequency converter, stator formed rotating field, dragged the rotor rotation.Coder 5 is the absolute locations that are used for measuring motor speed and stator and rotor magnetic field, and frequency converter is done correct operation by setting the anodontia towing machine of requirement driving after obtaining these signals.Traction sheave 15 is installed on the rotor field spider 13 with rotor coaxial, mutually between flush fit, be processed with grooving on it, on grooving, place hoist ropes 5.The support end face has indent sipes 16, and traction sheave is in the indent sipes 16 of support.When rotor rotation, traction sheave rotates simultaneously with rotor, and hoist ropes drives the upper and lower operation of car.Drg 6 is by electromagnet 1, armature 2 is formed, magnet coil and pressure spring are arranged on the electromagnet, the friction lining 7 of great friction coefficient is installed on the end face of armature, friction lining 7 on the armature end face is corresponding with the rotor field spider wheel rim in the support, when elevator when pulling in or being in a state of emergency (et out of order or sudden power), the outage of drg magnet coil, because the screen resilience of pressure spring, compressing armature makes the friction lining 7 on the end face be tight against rotor field spider 9 outer rims (holding concurrently when the brake wheel effect), thereby make the traction sheave stall, car remains on position of stopping (normal operation) or braking deceleration operation (emergency state).When normal operation, the magnet coil energising attracts armature, makes it to break away from the support outer rim, the traction sheave normal operation.Handle 8 is housed on drg,, car low speed is slided pull in for declutching in the emergency state.
The anodontia towing machine of frame-type of the present invention is with the support of cube shaped framework as towing machine, and has mounting hole on four attachment faces of support, and it can adopt five kinds of mounting meanss of Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to be installed in the hoistway.
Shown in Figure 4, employing be wall-hanging installation, traction sheave 15 towards wall, is fixed on it on the hoistway framework by support 4 fwd mounting holes 3 and bolt of rear end plate 17.Make under the car and hang.
Shown in Figure 5, employing also be wall-hanging installation, with traction sheave 15 parados, the mounting hole 3 by bolt of rear end plate 17 and support 4 back is fixed on it on the hoistway framework, makes under the car to hang.
Shown in Figure 6, employing be that suspension type is installed, mounting hole 3 and the bolt of rear end plate 17 of support 4 end faces by it is installed under the end face of hoistway, make extension car under.
Fig. 7 adopts the footing mounting means, and promptly the underrun of support 4 its mounting hole 3 and bolt of rear end plate 17 are installed on the support of hoistway, makes under the car and hangs.
Fig. 8 adopts the footing mounting means, and underrun its mounting hole 3 and the bolt of rear end plate 17 that are about to support 4 are installed on the pit of hoistway, and towing machine is placed on the pit, hang on the car.
The user can select a kind of mounting means to install arbitrarily according to the hoistway designing requirement of oneself.
