Abstract

The utility model discloses a driving elevator, which comprises a lift car and two guide rails. The two guide rails are arranged on the two sides of the lift car, the guide rails are fixed on a hoistway, the driving elevator further comprises a permanent magnet synchronous motor driving wheel group, the permanent magnet synchronous motor driving wheel group is arranged on the joint of the lift carand the guide rails, the permanent magnet synchronous motor driving wheel group comprises a driving wheel, a tensioner, and a permanent magnet synchronous motor, the driving wheel and the tensioner are respectively positioned on the two sides of and propped with the guide rails, and the driving wheel is connected with the permanent magnet synchronous motor. The utility model has the following advantages: the lift car of the driving elevator enjoys a reduction in the deadweight, and requires no addition of a weight iron; and the driving elevator is not required to be equipped with a dragging machine machine room, and therefore occupies a small construction area, consumes less amount of steel, is low-cost, energy-saving and environment-friendly.

Description

Drive elevator

Technical field

The utility model is about a kind of elevator field, more particularly, and about a kind of driving elevator.

Background technology

At present, the jacking equipment elevator that is widely used in vertical transportation means of delivery in the building mainly is made up of towing machine (winch), guide rail, counterweight, safety device (as velocity limiter, safety tongs and energy disperser etc.), signal manipulation device, car and Room door etc.Existing elevator is to be traction-type mostly, guarantees cage operation by increasing traction sheave and hoist ropes friction force, and car will have enough deadweights, and balance weight iron also will have corresponding weight, therefore, has strengthened rolled steel dosage, has increased towing machine power.And, exist to take that space is big, steel consumption big, the more high shortcoming of cost.

The utility model content

In view of this, main purpose of the present utility model is to provide a kind of and can saves space and can save steel, environmental protection and lower-cost driving elevator.

In order to achieve the above object, the technical solution of the utility model is achieved in that a kind of driving elevator, it includes car and guide rail, the both sides of described car are respectively arranged with described guide rail, described guide rail is fixed on the hoistway, it also includes permagnetic synchronous motor and drives wheels, described permagnetic synchronous motor drives the junction that wheels are arranged on described car and guide rail, described permagnetic synchronous motor drives wheels and includes driving wheel, expansion tightening wheel and permagnetic synchronous motor, described driving wheel and described expansion tightening wheel lay respectively at described guide rail both sides and with described guide rail butt, described driving wheel is connected with described permagnetic synchronous motor.

Described driving elevator also comprises safety device, and described safety device comprises safety tongs, door opener, gate, Room door, energy disperser and velocity limiter.

Described driving elevator also includes artificial salvage gear, and described artificial salvage gear includes the retinue chain and drives handwheel.

Described driving elevator also includes electric apparatus, and described electric apparatus includes control box, maneuver box, throw-over switch, leveling switch and speed limiting switch.

Beneficial effect after the employing technique scheme is: the weight reduction of car in the driving elevator of the present utility model does not need to increase balance weight iron; And, need not to be provided with the towing machine machine room, the space that takies is little, the consumption steel are less, cost is low, energy-conserving and environment-protective.
