Description

The elevator that a kind of spool type drives

Technical field:

The utility model relates to a kind of elevator, and the elevator that particularly a kind of spool type drives belongs to the technical field that elevator is made.

Background technology:

At present, the most widely used still traction-type of the actuating device of domestic and international elevator, this is because the unrestricted cause of hoisting depth that traction-type drives.But during the low velocity elevator that uses in low-rise building, this traction elevator has not just had advantage.Hydraulically powered elevator is applicable to low layer, low speed, still, the hydraulic elevator complex structure, the cost height, leakage of oil easily is difficult for promoting." novel elevator that a kind of spool type drives " of Chinese patent 200520012299.9 provides this and be applicable to the low velocity elevator that uses in low-rise building, but the reel of this elevator processing inconvenience, also inconvenience is installed, and makes troubles to production.

Summary of the invention:

The purpose of this utility model provides the elevator that a kind of spool type drives, it is to adopt conventional two shaft reductors that the reel separated into two parts also is installed in both sides respectively, thereby, the length of reel is divided into two, make processing, installation all make things convenient for the Cargo Lift of the low velocity that the utility model is suitable for installing and using most in low-rise building.

The purpose of this utility model is that the elevator that has adopted a kind of spool type by following structure to drive is realized: it is made up of drum type winder, steel rope, container, hoistway four parts; Drum type winder is installed in the top of hoistway, container is installed between the two interior side rails of hoistway, two above wire line shoes are used at the two ends of steel cable respectively, be fixed on the outer end end cap of reel at two ends of drum type winder, the stage casing is stretched to the below and is passed two fixing container pulleys of container top respectively, the cover that upwards steel rope is formed again is sleeved in the equalizer pulley below the frame of drum type winder.Like this, in drum type winder when work,, the forward or reverse of two ends reel just makes steel rope fixed thereon be reeled or return, thereby, drive by steel rope makes rising or decline between the guide rail of container in hoistway, has realized the upper and lower cargo-carrying purpose of elevator.Elevator is in operation simultaneously, obtains self-equalizing in the equalizer pulley of length residual quantity below the drum type winder frame of suit that produces when reel in the steel rope two ends.Because the elevator standard regulation steel rope one deck of can only on reel, reeling, like this, limited just that the utility model is inapplicable to be installed in skyscraper, generally be applicable to the following Cargo Lift of five floors is installed.

The drum type winder of the elevator that a kind of spool type of the present utility model drives, by reductor, both sides reel, frame, drg, electrical motor becomes with the balance assembly pulley, and frame is processed into rectangular frame, and two ends are fixed on the interior guide rail that matches of hoistway, reductor is installed above the middle part to be connected wheel with electrical motor and employing, drg entangles wheel, is fixed on the frame 1b, for simplified structure is of the present utility model wheel is used as brake wheel; The pulley base of equalizer pulley adopts bolt to be fixed on the following centre of frame.

The reductor of drum type winder of the present utility model adopts the various common reductor of double output shaft.

The frame of drum type winder of the present utility model is processed into rectangular frame, two ends length cooperates with the guide rail that is installed in hoistway, width is greater than reductor and the size that is connected electrical motor, be processed with above the middle part for reductor, electrical motor, the fixing screw of drg are installed, below the centre be processed with for the fixing screw of the pulley base that equalizer pulley is installed.

The both sides reel of drum type winder of the present utility model adopts identical structure, that is: stack shell is one section steel cylinder, the grooving that surface working matches with steel rope, two ends are welded with the end cap of retaining rope, the centre is welded with the axle concentric with the mandrel surface circumference, a wherein end of axle is processed with the hole of matching with speed reducer output shaft, the axle that other end processing cooperates with bearing bore.

The both sides reel of drum type winder of the present utility model adopts identical structure, and the structure of reel also can adopt the cast iron method to be cast as the integral structure identical with the welding method moulding.

When reel was installed, the nose end of two drum shaft was connected with the shaft sleeve of reductor two ends output respectively, and the other end is fixed by bearing seat and frame after bearing is installed, and the pulley base of equalizer pulley is fixed on the middle part below the frame.

The frame of drum type winder of the present utility model is processed into rectangular frame, two ends length cooperates with the guide rail that is installed in hoistway, width is greater than reductor and the size that is connected electrical motor, the middle part is installed reductor and with electrical motor and employing wheel is connected, drg entangles wheel, and is fixed on the frame, for making compact conformation of the present utility model and reducing production costs, the utility model just will use as brake wheel wheel, and two combine into one for two kinds of accessory functions.

The steel rope of reductor of the present utility model, container, hoistway all are conventional elevator accessory and structures.Other parts have not just been narrated one by one.

The elevator that the utility model drives owing to a kind of spool type that has adopted said structure, thus the elevator cost height in the low-rise building, installation inconvenience and the many problems of fault rate solved, and also simple in structure, convenient for maintaining, principle is easy-to-understand, holds susceptible to user acceptancely, makes things convenient for penetration and promotion.
