Abstract
A kind of two pull-behind lift, comprises hoistway, is arranged at the car in described hoistway, and be arranged at described well headroom and be connected with described car and drive the actuating device of this cage operation, and described actuating device comprises two towing machines mutually linked.The utility model adopts two towing machines to drive, and stability is better, and reliability is higher.
Description
Technical field
The utility model relates to a kind of two pull-behind lift, belongs to elevator and manufactures field.
Background technology
Traction elevator, with its feature easily, in today that living standard significantly improves, is widely used in middle and high layer building.The conventional structure of traction elevator drives car lifting by towing machine, to reach the object that conveying people arrives designated floor.Towing machine is the sole power source of elevator, is also the vitals that in car, passenger survival ensures.Therefore conventional traction elevator is all provided with large amount detecting device for ensureing the normal work of towing machine, is also provided with a large amount of safety device for protecting car when towing machine fault simultaneously.
Utility model content
The utility model, for solving prior art problem, provides two pull-behind lifts that a kind of safety performance is higher.
The technical solution of the utility model is: a kind of two pull-behind lift, comprise hoistway, be arranged at the car in described hoistway, and be arranged at described well headroom and be connected with described car and drive the actuating device of this cage operation, described actuating device comprises two towing machines mutually linked.
As preferably, two described towing machine rotating speeds are identical, and are connected with described car by the traction sheave of formed objects.
As preferably, be interconnected by torquer between the rotating shaft of two described towing machines.
As preferably, described towing machine comprises variable-frequency motor and controls the frequency converter of described variable-frequency motor rotating speed, and described torquer is connected with described frequency converter and controls described frequency converter work.
As preferably, described traction sheave is connected with described car top by wirerope; Each described traction sheave is connected with described car top respectively by independently wirerope.
As preferably, described car top is provided with the level indicator be connected with described frequency converter.
As preferably, described car top is connected with an equalizer bar, and described equalizer bar is provided with the transition wheel that two are in same level height; Two described transition wheels are placed in below two described traction sheaves respectively, and are connected with two described traction sheaves by wirerope.
As preferably, between two described transition wheels, be provided with trammel beam, described trammel beam be provided with the level indicator be connected with described frequency converter.
As preferably, described equalizer bar and described car hinged.
Different from the elevator of routine, the utility model elevator setting has two towing machines, can adopt the towing machine that two power is the same, connects the traction sheave of same size, jointly drives cage operation.Be interconnected by torquer between the rotating shaft of two towing machines, once two towing machine rotating speeds are different, torquer can record difference in torque, is adjusted the rotating speed of two towing machines by frequency converter, makes two towing machines remain synchronous.The utility model can adopt the towing machine that power is lower during fabrication, and the towing machine of two smaller powers under the identical prerequisite of configuration cost definitely lower than the towing machine of a higher-wattage.Traditional car is all driven by a wirerope, and the utility model adopts two towing machines to drive, and the stability of car is higher.In elevator manufacturer's standard, the load of towing machine must leave surplus, therefore when the towing machine of in the utility model breaks down, another towing machine still can work a period of time under extreme conditions, though normal use can not be ensured, but can play certain rescue effect, avoid traditional traction elevator towing machine once fault, passenger can only lock into the widely different border waited for rescue in car.
The traction sheave be connected with two towing machines can be connected with car respectively, is controlled by the level indicator be installed on car, makes two towing machines keep synchronous, stabilized driving cage operation; Meanwhile, the connection of this structure, can avoid wirerope self to reverse the moment of torsion of generation to the rotation stress of car generation level, promote car degree of stability further.Two towing machines also drive car by equalizer bar, this structure when one of them towing machine fault and ineffective time, the equalizer bar hinged with car can rotate, wirerope as far as possible between stretching car and residue traction sheave, alleviate the load of residue towing machine, promote the period of service of residue towing machine, promote safety.
In sum, the utility model has the following advantages:
1, adopt two towing machines to drive, stability is better, and reliability is higher;
2, towing machine cost is lower.
