Description
Technical field
The utility model relates to the elevator technology field, relates in particular to a kind of non-counterweight elevator.
Background technology
Publication number is that the patent documentation of CN2538762Y discloses a kind of pull-type hydraulic elevator lifting mechanism that falls, oil cylinder adopts pull-type oil cylinder or two-way cylinder, the plunger of this oil cylinder is walked around the assembly pulley that is made of a fixed pulley at least through counterweight by hauling rope from a side, be connected with the car of opposite side, constitute hydraulic pressure with this and draw high and put the elevator lifting mechanism of falling two kinds of mode of operations.This structure utilizes pull-type oil cylinder or two-way cylinder can bear the characteristic of relay, is equipped with balance weight, connects and composes by assembly pulley and car again.But, because said structure adopts balance weight, so must adopt guidance system that counterweight is led, elevator device complexity and quality have been increased like this, improve the load bearing requirements of hauling rope, assembly pulley, caused the elevator hoistways space to increase, increased elevator building cost and use cost.In addition, adopt the Backpack type structure of side lifting, also increased the complexity and the cost of lift car.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this utility model provides a kind of non-counterweight elevator, has effects such as simple in structure, reliable, that the elevator hoistways space is little, energy-conservation.
To achieve the above object, the utility model has adopted following technical scheme:
A kind of non-counterweight elevator, comprise car, car is along guiding rail lifting in hoistway, be provided with in the described hoistway and draw actuating device and assembly pulley, described assembly pulley to comprise at least one group of movable pulley and at least one group of fixed pulley, fixed pulley is installed in well headroom, movable pulley is installed in the pull end that falls that draws actuating device, hauling rope one end is fixed on well headroom, and behind pile warp movable pulley and the fixed pulley, the other end is captiveed joint with car.Adopt no counterweight scheme, reduced elevator complexity and quality, reduced the load bearing requirements of hauling rope, assembly pulley, cause the elevator hoistways space requirement to reduce thereby reduced the assembly pulley size, the building and installation cost and the use cost of elevator reduce greatly like this.And, because adopt pull-type actuating device, be stressed all the time so lift car in the uplink and downlink process, draws the traction end that draws of actuating device, guaranteed the reliability service of elevator like this.
Wherein, described pulley should be from broad understanding, comprises rope sheave with similar transmission agency, belt wheel, sprocket wheel etc.; Described hauling rope should be from broad understanding, comprises rope with certain flexibility, driving band, chain etc.Here " one group of fixed pulley " is meant the fixed pulley of one or more coaxial rotation, " one group of movable pulley " is meant the movable pulley of one or more coaxial rotation, the notion of why introducing " group " is because be that a plurality of pulleys constitute one group of use mostly in the elevator field, equally, hauling rope also is that the mode with " group " occurs, and realizes that promptly the hauling rope of same transfer function has many.Described assembly pulley is meant by some groups of above-mentioned fixed pulleys and some groups of above-mentioned movable pulleys and constitutes.It is described that to fall pull-type actuating device can be pull-type hydraulic ram, also can be towing machine etc. other can realize drawing the device of effect.
As preferably, above-mentioned draw actuating device fall pull end for there not being the guiding free end.This pulling force that draws traction end only need bear on the above-below direction gets final product, there are not counterweight pressure and inertial mass, can not deposit rocking or going here and there in the other direction, so adopt and do not have the guiding free state, convenient installation, cost-cutting are avoided the counterweight guiding and the inconsistent problem that causes of car guiding that originally may occur.
As preferably, described hauling rope is for being fixedly connected on two groups of hauling ropes of the relative both sides of car respectively.Adopt both sides application of force traction car, guarantee that cage operation is smooth and easy, simplify car structure, and then reduce the car quality.
More preferably, position center symmetry in the car level face that described two groups of hauling ropes are captiveed joint with car, the stressed balance more of car like this.
As preferably, relative both sides respectively are provided with one and draw actuating device in the described hoistway, two are drawn actuating device respectively to captive joint with car through assembly pulley by one group of hauling rope, and two groups are drawn the installation site of actuating device and connection location center symmetry in the car level face of cooresponding hauling rope and car thereof.Adopt two to draw actuating device, two cover assembly pulleys, two side-lining cars, use so at double the quantity of hauling rope, therefore the diameter of hauling rope is reduced, diameter of pulley in the assembly pulley reduces simultaneously, thereby the headroom height and the pit depth dimensional characteristic of elevator hoistways in the building reduced.In addition, because hauling rope is connected in the both sides of car, therefore the requirement for car structure two edge-on beams and upper beam etc. is minimized, and makes the more reasonable stress of car, and it is simple that the structure of car is tending towards.And the stressed balance more of car is moved smooth and easy reliable.
When adopting single group hauling rope to draw car, hauling rope preferably is fixedly connected on car top central authorities; When adopting two groups or when organizing hauling rope, described hauling rope is fixedly connected on car top or all can in the car bottom more.
Above-mentioned hauling rope is a steel rope.The transmitting ratio of above-mentioned assembly pulley can be 1:2,1:3 or 1:4.
The utility model is owing to adopted above technical scheme, adopt no counterweight scheme, elevator complexity and quality have been reduced, reduced the load bearing requirements of hauling rope, assembly pulley, cause the elevator hoistways space requirement to reduce thereby reduced the assembly pulley size, the building and installation cost and the use cost of elevator reduce greatly like this.And, because adopt pull-type actuating device, be stressed all the time so lift car in the uplink and downlink process, draws the traction end that draws of actuating device, guaranteed the reliability service of elevator like this.
