Abstract
The utility model discloses an equipment room free traction sheave type elevator which comprises a cage, a counterweight, a driving and controlling system that is provided with a tractor. The utility model is characterized in that: the cage is provided with at least two groups of cage rope sheave modules, and each cage rope sheave module comprises at least two cage rope sheaves, a hoisting rope goes from one fixed point inside the well downwards and twists one group of the cage rope sheave module which is fixed on the cage before twisting a direction alternation sheave and going back to the other cage rope sheave module that is fixed on the cage. Then, the hoisting rope that lifts the cage twists the traction sheave and the other side where the hoisting rope twists the traction sheave is provided with the counterweight. The traction ratio of the elevator is 4 to 1, thus the power of the tractor can be reduced. The equipment room free structure is applicable for elevator that has large carrying capacity. Within the elevator, the tractor can be positioned at the top of the well or the bottom of the well to save space and energy and provide more choices for consumers and designers of the elevator.
Description
Technical field the utility model relates to a kind of roomless traction cable pulley type elevator, and this kind elevator can be applicable to not have machine room civil engineering hoistway or do not have machine room steel structure hoistway, can also be applied in Retrofit of Elevator and hydraulic elevator and make in the remodeling of towed elevator.
Background technology is in traditional traction elevator, and elevator(lift) machine room occupies very big ratio in the required space of elevator, if adopt machine-roomless lift, just can save this part space, just is equivalent to economize on resources and cost for the user.The project that has some to install elevator additional and transform elevator in addition should adopt the machine-roomless lift structure, and such elevator structure does not require machine room, can reduce a lot of restrictions of construction conditions aspect, satisfies more demands of user.And most of traction ratio that adopts 1: 1 and 2: 1 in traditional towed elevator, the ratio that is linear velocity and the rising or falling speed of car of towing machine rope sheave is 1 or 2 times, required towing machine power and axle load are all bigger, towing machine build and weight are all very big, therefore, this elevator adopts mostly computer room structure, and the general maximum of the load carrying ability of the machine-roomless lift of 2: 1 structures can only reach 1600kg.It is organic machine room-free elevator of 4: 1 that traction ratio is also arranged at present, but is used as the large-tonnage cargo lift, and only arrange a secondary car sheave on the car of this kind elevator more, therefore very high to the car frame requirement of strength that this secondary car sheave is installed.
Summary of the invention is at above-mentioned reality, the utility model provides a kind of roomless traction cable pulley type elevator, the traction ratio of this kind elevator is 4: 1, towing machine power is reduced, towing machine build and weight all can reduce, and can and adopt gearless machine to adapt to the big elevator of load carrying ability with no machine room structure; In this kind elevator, towing machine can be placed on well headroom (on put), also can be placed on hoistway bottom (underlying), and it can satisfy the needs of saving space, simultaneously again can energy savings, give client and elevator design personnel with more choice like this.
The purpose of this utility model is achieved in that
A kind of roomless traction cable pulley type elevator, comprise car, counterweight, comprise towing machine at interior driving control system, car is provided with car sheave, counterweight is provided with counterweight sheave, in elevator hoistways, be provided with and turn to rope sheave, the lifting rope ends is fixed on the hoistway attachment point, car and counterweight are respectively by the both sides of the lifting rope hanging of walking around car sheave and counterweight sheave at the traction rope sheave of towing machine, it is characterized in that: be provided with two groups of car sheave groups on the described car at least, wherein every group of car sheave group has two car sheaves at least, the lifting rope is descending and walk around after the one group of car sheave group that is fixed on the car up and walk around and turn to the descending again wraparound of rope sheave to another car sheave group that is fixed on the car by an attachment point in the hoistway, subsequently, lifting the lifting rope of car and is walked around the traction rope sheave, and the opposite side suspention that the lifting rope is walked around behind the traction rope sheave has counterweight.
When towing machine is arranged on well headroom, described lifting rope is descending and walk around the one group of car sheave group that is fixed on the car by an attachment point in the hoistway, up then and walk around and turn to the descending again and wraparound of rope sheave to another group car sheave group that is fixed on the car, the lifting rope that car in lifting is up and walks around the traction rope sheave, come downwards to a counterweight sheave that is fixed on the counterweight then, walk around behind this counterweight sheave uply again immediately and walk around another and turn to rope sheave, last lifting rope is after having passed through descending and having walked around another to be fixed on counterweight sheave on the counterweight on the up attachment point that is fixed in the hoistway.
And when towing machine is arranged on the hoistway bottom, described lifting rope is descending and walk around the one group of car sheave group that is fixed on the car by the attachment point in the hoistway, up then and walk around and turn to rope sheave descending again and walk around to another car sheave group that is fixed on the car, the lifting rope that car in lifting need up and the guiding that turns to rope sheave through an increase after, descending and walk around behind the traction rope sheave up, the lifting rope is after having passed through the guiding that turns to rope sheave of another increase, come downwards to a counterweight sheave that is fixed on the counterweight, walk around behind this counterweight sheave uply again immediately and walk around and turn to rope sheave, last lifting rope is after having passed through descending and having walked around another to be fixed on counterweight sheave on the counterweight on the up attachment point that is fixed in the hoistway.
The described rope sheave that turns to is positioned at well headroom, and is that to turn to rope sheave all be the both sides that lay respectively at towing machine for towing machine two when being arranged on well headroom four when turning to rope sheave or towing machine to be arranged on the hoistway bottom.
Be parallel to each other by formed two perpendiculars of each rope sheave radial center in each car sheave group respectively and lay respectively at both sides by the formed vertical plane in car guide rail center.
Be parallel to each other by formed two perpendiculars of each rope sheave radial center in each car sheave group respectively and all be positioned at a side by the formed vertical plane in car guide rail center.
Be parallel to each other by formed two perpendiculars of each rope sheave radial center in each car sheave group respectively and by many to the car guide rail center between formed each vertical plane.
The car sheave group can be arranged on the top of car, and in this case, the lifting rope passes through from car top by the car sheave group.
The car sheave group also can be arranged on the bottom of car, and in this case, the lifting rope passes through from the car bottom by the car sheave group.
Use elevator of the present utility model and can embody following advantage:
