Abstract
The utility model discloses an underlying indirect-drive elevator which comprises an active drive system and a passive suspension system. The active drive system comprises a traction machine (1) at the bottom of a hoistway. A traction rope (2) is arranged on a traction wheel of the traction machine (1). One end of the traction rope (2) passes around counterweight lower sheaves (4) arranged on the lower portion of a counterweight (3 to be connected with a base (5). The other end of the traction rope (2) sequentially passes around a top diversion sheave (6) disposed on the upper portion of the hoistway and counterweight upper sheaves (7) disposed on the upper portion of the counterweight (3) and is connected with an automatic tensioner (8) disposed on the upper portion of the hoistway. The passive suspension system comprises a steel wire rope (9) fixed above the counterweight. The steel wire rope (9) passes by top guide wheels (10) to be fixed to the top of a car (11). By the use of the underlying indirect-drive elevator, the traction machine is miniaturized, energy consumption is lowered, elevator cost is lowered, and great social benefit is created.
Description
Technical field
The utility model relates to a kind of Indirect driven elevator, and characteristics relate to a kind of underneath type Indirect driven elevator.
Background technology
At present, most of elevators are the tractive driving mode, and namely the Action of Gravity Field by car and counterweight overcomes the potential energy of both generations of poor quality at the friction force that traction sheave forms, and drive lift car and move up and down.The shortcoming of this kind type of drive is along with the elevator loading amount increases, car, counterweight quality and increase simultaneously with the quality of rated load matched, these loads all act in the driving, load and the moment of torsion of drive shaft have greatly been increased, produce the friction force that enough drives the elevator operation, can assurance device normally, safe operation, otherwise, not only can not satisfy normal operation, go back entail dangers to the safe operation of elevator.Therefore, how to research and develop a kind of novel failure-free elevator structure and type of drive, make towing machine only drive this fractional load of difference of car and counterweight quality, thereby make towing machine miniaturization and low energy consumption, become the problem that industry needs to be resolved hurrily.
The utility model content
The purpose of this utility model is, a kind of underneath type Indirect driven elevator is provided.Effect of the present utility model is to reduce drive system for the weight requirement of lift car or counterweight, has effectively realized miniaturization and the low energy consumption of towing machine, has reduced the elevator cost, has produced larger social benefit; The utility model can also reduce elevator operation noise well simultaneously.
The technical solution of the utility model: underneath type Indirect driven elevator, comprise active drive system and driven suspension, described active drive system comprises the towing machine that is arranged on the hoistway below, the traction sheave of towing machine is provided with hoist ropes, and an end of hoist ropes is walked around the counterweight lower sheave that is arranged on the counterweight bottom and is connected with pedestal; The other end of hoist ropes is walked around the top diversion sheave that is arranged on the hoistway top, the counterweight top sheave that is arranged on counterweight top successively, and is connected with the automatic tension device that is arranged on the hoistway top; Described driven suspension comprises the steel rope that is fixed on the counterweight top, and it is fixing with the car top that steel rope is walked around the top guide wheel.
In the above-mentioned underneath type Indirect driven elevator, described towing machine is arranged in the hoistway the position below the re-projection.
In the aforesaid underneath type Indirect driven elevator, be fixed with Manual tightening device on the described pedestal, an end of hoist ropes is connected with the Manual tightening device on being fixed on pedestal.
Compared with prior art, the utility model has improved the tractive driving condition of elevator, common traction drive unit, car and counterweight quality must reach the requirement that certain value can satisfy tractive driving, if can not reach, will produce the skidding between wirerope and traction sheave, produce easily noise, can have an accident when serious.Propulsive effort of the present utility model resolves into suspended structure and tractive driving structure two parts of Indirect driven, reduced greatly the requirement to towing machine main shaft size, effectively realize miniaturization and the low energy consumption of towing machine, reduced the elevator cost, produced larger social benefit; The utility model can also reduce elevator operation noise well simultaneously.As further preferred, towing machine of the present utility model is arranged in the hoistway the position of re-projection below, when improving the hoistway space degree of utilization, has reduced the carrying of building top, significantly reduces building cost.
