Abstract

A screw elevator with a counterweight device is characterized by comprising a counterweight, a steel wire rope, a sheave, a car, a screw, a drive nut with a gear, and a drive motor. The sheave is fixed at the top of a hoistway through a fixed seat and rotatably supported on the fixed base through a rotary shaft, one end of the steel wire rope is fixedly connected with the counterweight, the other end of the steel wire rope passes around the sheave to be fixed on the car, the screw is perpendicularly mounted in the hoistway, the upper end and the lower end of the screw are fastened to the top and the bottom of the hoistway respectively, a case is fixed on the car, the drive nut is disposed in the case, the drive nut is supported by an upper bearing and a lower bearing inside the case and screwed on the screw, the drive motor is mounted on the case, a gear is mounted at an extending end of the drive motor, and the gear disposed in the case is meshed with the gear on the drive nut. Compared with the prior art, the screw elevator has the advantages that the elevator with the screw bearing main pulling stress is not easy to shake and deform, weigh of the car and a load are exerted on the nut only partially, and both power and size of the motor can be reduced greatly.

Description

The screw rod elevator of band counterweight

Technical field

The utility model relates to a kind of screw type elevator structure, belongs to the elevator technology field.

Background technology

Because it is simple in structure that screw-rod structure as far as low floor elevator, has, the advantage that cost is low, so, obtain certain application at some floor.Existing screw-rod structure elevator mainly contains following several kinds:

1 screw mandrel only moves axially, and is connected with lift car, and the nut axial restraint only rotates, and when nut rotated, screw mandrel drove car and moves up and down, for example: Chinese patent 201020189986.9.

The problem that this structure exists is: the gravity of car and load-carrying all is applied on the screw mandrel, and screw mandrel is longer, and it is crooked that pressurized is prone to unstability, and the total weight of car, load-carrying, screw mandrel all is applied on the nut, and the nut wearing and tearing are big, and power of motor consumption is big.

2 screw mandrels are fixed, and nut can rotate and with the car up-and-down movement, for example: Chinese patent: 2005101082156, though this structure has been avoided the state of screw mandrel pressurized, but there is following problem:

The defective that this structure exists is: the total weight of car, load-carrying all is applied on the nut, and the nut wearing and tearing are big, and power of motor consumption is big.

3 nuts are fixed, and screw rod rotates, and when screw rod rotates, just drive car, load-carrying is moved, and same, the total weight of this structure car, load-carrying all is applied on the nut, the nut wearing and tearing greatly, power of motor consumption is big.

Summary of the invention

The purpose of the utility model provides a kind of screw rod and mainly bears tensile stress, is difficult for buckling deformation, and, have only the part weight of car and load-carrying to be applied on the nut, the screw rod elevator that power of motor and volume can be dwindled significantly.

The utility model is achieved in that and comprises pouring weight, steel rope, pulley, car, screw rod, drive nut, motor that pulley is fixed on the top of hoistway through permanent seat; Pulley through the rotating shaft pivoting support on permanent seat, steel rope one end with pouring weight is captiveed joint, the other end is walked around pulley and is fixed on the car; Screw rod is vertically mounted in the hoistway, and the top of two ends and hoistway and bottom are fastening up and down, is fixed with cabinet on the car; Be provided with drive nut in the cabinet, drive nut by in the cabinet up and down two bearings support and screw on screw rod, drive motor is installed on the cabinet; Motor shaft extension end is equipped with gear, the gear mesh on this gear and the drive nut.

During work, motor shaft drives the drive nut rotation, and cabinet and car move up and down together thereupon, when car moves, pouring weight is dragged down to the car opposite-oriented movement at steel rope.

To the weight of pouring weight greater than car weight; Weight=car weight+equilibrium factor (0.4~0.5) * load-carrying to pouring weight; If equilibrium factor gets 0.5, the power that at full load, drive nut are applied on the screw rod is merely 0.5 times of load-carrying; Be the elevator of load-carrying 400kg, the power on screw rod that is applied to just has only 200kg.

Stable in order to guarantee car, reduce to rock, two vertical and be parallel to each other guide rails have been arranged in invention in hoistway, car is slidingly arranged on two guide rails.Employing guide rail guiding, more safe and reliable.

The utility model compared with present technology, its beneficial effect is:

1 screw rod mainly bears tensile stress, is difficult for buckling deformation

2 power on screw rod that are applied to are very little, and screw rod can be used small dimension, and material is economized, and cost is low.

3 adopt weight structure, can reduce power of motor, dwindle motor volume, reduce motor cost.

4 adopt guide rail that car is led, safety, stable.

Description of drawings:

Fig. 1 is the structural representation of the utility model;

Fig. 2 is the F-F cutaway view of Fig. 1

Fig. 3 is the partial enlarged view of I among Fig. 1;

To pouring weight 1, guide rail 2, steel rope 3, hoistway 4, car 5, pulley 6, gear 7, motor 8, screw rod 9, head bearing 10, cabinet 11, drive nut 12, lower bearing 13, rotating shaft 14, permanent seat 15, gear 16.

The specific embodiment:

Combine accompanying drawing and embodiment that the present invention is done describes in further detail at present:

The utility model comprises pouring weight 1, steel rope 3, pulley 6, car 5, screw rod 9, the drive nut 12 that has gear 16, motor 8, and pulley 6 is fixed on the top of hoistway 4 through permanent seat 15, pulley 6 through rotating shaft 14 pivoting supports on permanent seat 15; Steel rope 3 one ends with pouring weight 1 is captiveed joint; The other end is walked around pulley 6 and is fixed on the car 5, and screw rod 9 is vertically mounted in the hoistway 4, and the top and the bottom of two ends and hoistway 4 are fastening up and down; Cabinet 11 is fixed on the car 5; Drive nut 12 is arranged in the cabinet 11, and drive nut 12 is supported and screwed on screw rod 9 by cabinet 11 interior two bearings up and down 10,13, and motor 8 is installed on the cabinet 11; The shaft extension end of motor 8 is equipped with gear 7, this gear 7 be positioned at cabinet 11 and with drive nut 12 on gear 16 engagement.

To the weight of pouring weight 1 greater than car 5 weight.Weight=car weight+equilibrium factor (0.4~0.5) * load-carrying to pouring weight 1 is provided with.
