Abstract

The invention discloses a screw rod elevator with a counterweight. The screw rod elevator is characterized by comprising a counterweight block, a steel wire rope, a pulley, a cage, a screw rod, a driving nut with a gear, and a motor, wherein the pulley is fixed on the top of a well path through a fixing base, and is rotationally supported on the fixing base through a rotating shaft; one end of the steel wire rope is fixedly connected with the counterweight block, and the other end of the steel wire rope is fixed on the cage by rounding the pulley; the screw rod is vertically arranged in the well path; the upper end and the lower end of the screw rod are fastened with the top and the bottom of the well path; a cabinet is fixed on the cage; the driving nut is arranged in the cabinet, and is supported and screwed on the screw rod through upper and lower bearings in the cabinet; the driving motor is arranged on the cabinet; and a gear is arranged at a shaft extending end of the motor, is arranged in the cabinet and is meshed with the gear on the driving nut. Compared with the prior art, the screw rod elevator has the advantages that: the screw rod is mainly used for bearing stress, so that destabilization and deformation are prevented; and moreover, only a part of the weights of the cage and a load are applied to the nut, so that the power and the size of the motor can be reduced greatly.

Description

The screw rod elevator of band counterweight

Technical field

The present invention relates to a kind of screw type elevator structure, belong to the elevator technology field.

Background technology

Because it is simple in structure that screw-rod structure for 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:

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, the easy unstability bending of pressurized, 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 maintain static, 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 are the following problems:

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 just drive car when screw rod rotates, 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 this invention is to provide a kind of screw rod and mainly bear tensile stress, be 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 present invention realizes like this, comprise pouring weight, steel rope, pulley, car, screw rod, drive nut, motor, pulley is fixed on the top of hoistway by permanent seat, pulley by 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, the top of two ends and hoistway and bottom are fastening up and down, are fixed with cabinet on the car, are 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, and 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 moved to the car opposite sense under steel rope drags.

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, at full load, the power that drive nut is applied on the screw rod only is 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 present invention compared with the prior art, 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.
