Description
Technical field
The utility model relates to a kind of elevator.
Background technology
The vertical conveyor of elevator to be a kind of with motor be power, is equipped with box like gondola, takes advantage of people or carrying goods for tier building.Vertical lift elevator has a car, operates in the vertical or leaning angle of at least two row and is less than between the rigid guideway of 15 °.Car size and version are convenient to passenger and are come in and gone out or handling goods.Existing elevator realizes the lifting of car by traction motor, traction sheave, traction steel-cable, owing to have employed frictional wheel drive-draw mode, greatly increases the hoisting depth of elevator.And traction derive from friction force, the size of friction force depends on friction coefficient and pressure.When friction coefficient is fixed, pressure is larger, and the friction force of generation is larger, and pulling ability is stronger.And larger pressure is provided, just need to increase the weight be carried on motor, that needs higher moment of torsion to electric machine rotation, and that just needs more electric energy, device-the counterweight offsetting car deadweight and certain load-carrying was set in the other side of car afterwards, energy-conservation target can be realized.The optimum regime that elevator runs is that the deadweight of car adds that load-carrying just in time equals the weight of counterweight.Equal in the power on traction sheave (being equivalent to provide the fixed pulley of power) both sides like this.And the power be applied on wheel is maximum, pulling ability is the strongest, and energy consumption only needs to overcome inertia force.Problem to be the load-carrying of elevator be change, and the quality of counterweight is changeless, as traction sheave both sides steel rope load capacity not etc., the increase of energy consumption of electrical machinery will be caused, and more ought tend to unloaded or more tend to the energy consumption of full elevator larger.
Utility model content
The purpose of this utility model is for prior art above shortcomings, provides a kind of counterweight balance elevator, and the load capacity that it can realize whenever traction sheave both sides steel rope is equal, thus realizes energy-conservation.
For achieving the above object, counterweight balance elevator of the present utility model, comprise traction motor, traction sheave, tension wheel, middle part is around in the traction steel-cable on traction sheave and tension wheel, one end of traction steel-cable connects with car upper end, the other end connects with counterweight upper end, it is characterized in that being provided with more than one rope sheave below car and counterweight, one one end compensating rope connects with car lower end, the middle part compensating rope is around on all rope sheaves, the other end compensating rope connects with counterweight lower end, guide rail is equipped with in the both sides of rope sheave, each guide rail all slides and is located at more than one compensation counterweight, each compensation counterweight is all connected by respective magnetic clutch and compensation rope, pressure sensor is provided with at car inner bottom part, pressure sensor is all connected with Programmable Logic Controller with all magnetic clutchs.
During work, traction sheave is driven by traction motor, the compensation rope increased makes it and traction steel-cable, car, counterweight forms loop configuration, no matter car is elevated, the car of traction sheave side adds steel rope and compensates rope and adds steel rope and compensate the weight of restricting can remain unchanged with the counterweight of opposite side, when the load-carrying in car changes, pressure sensor by this signal feedback to Programmable Logic Controller, the magnetic clutch that Programmable Logic Controller presses the side of operating conditions rope sheave closes with compensation knot, corresponding compensation counterweight is with the lifting of compensation rope one, make the load capacity of whenever traction sheave both sides steel rope equal, thus realize energy-conservation,
As further improvement of the utility model, described traction sheave is provided with connected straight trough and V-type groove, and straight trough is positioned at inside V-type groove, and the diameter of traction steel-cable is slightly larger than straight trough width; Traction steel-cable is stuck in the junction of straight trough and V-type groove, can increase the friction force of traction sheave and steel rope, is unlikely to steel rope and skids on the traction sheave, and safety is good;
In sum, the load capacity that the utility model can realize whenever traction sheave both sides steel rope is equal, thus realizes energy-conservation, and safety is good.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As Fig. 1, shown in Fig. 2, this counterweight balance elevator, comprise traction motor (not shown), traction sheave 1, tension wheel 2, middle part is around in the traction steel-cable 3 on traction sheave 1 and tension wheel 2, described traction sheave 1 is provided with connected straight trough 4 and V-type groove 5, straight trough 4 is positioned at inside V-type groove 5, the diameter of traction steel-cable 3 is slightly larger than the width of straight trough 4, one end of traction steel-cable 3 connects with car 6 upper end, the other end connects with counterweight 7 upper end, two rope sheaves 8 are provided with below car 6 and counterweight 7, one one end compensating rope 9 connects with car 6 lower end, the middle part compensating rope 9 is around on two rope sheaves 8, the other end compensating rope 9 connects with counterweight 7 lower end, guide rail 10 is equipped with in the both sides of two rope sheaves 8, each guide rail 10 all slides and is located at several compensation counterweight 11, each compensation counterweight 11 is all connected by respective magnetic clutch 12 and compensation rope 9, pressure sensor 13 is provided with at car 6 inner bottom part, pressure sensor 13 and all magnetic clutchs 12 all with Programmable Logic Controller (PLC, not shown) be connected.
During work, traction sheave 1 is driven by traction motor, and in elevator runs, car 6 and counterweight 7 are reverse direction operations, and when the position of car 6 at top layer, counterweight 7 will at bottom, car 6 is when bottom, and counterweight 7 runs to top layer, the compensation rope 9 increased makes it and traction steel-cable 3, car 6, counterweight 7 forms loop configuration, compensate rope 9 and also adopt steel rope, no matter car 6 is elevated, the car 6 of traction sheave 1 side adds traction steel-cable 3 and compensates the weight that rope 9 adds traction steel-cable 3 with the counterweight 7 of opposite side and compensate rope 9 and can remain unchanged, when the load-carrying in car 6 changes, pressure sensor 13 by this signal feedback to Programmable Logic Controller, weight as now car 6 side is greater than the weight of counterweight 7 side, then the magnetic clutch 12 of Controlled by Programmable Controller counterweight 7 side is combined with compensation rope 9, the compensation counterweight 11 of this side is with the lifting of compensation rope 9 one, weight as now car 6 side is less than the weight of counterweight 7 side, then the magnetic clutch 12 of Controlled by Programmable Controller car 6 side is combined with compensation rope 9, the compensation counterweight 11 of this side is with the lifting of compensation rope 9 one, make the load capacity of whenever traction sheave 1 both sides traction steel-cable 3 equal, thus realize energy-conservation, traction steel-cable 3 is stuck in the junction of straight trough 4 and V-type groove 5, can increase the friction force of traction sheave 1 and traction steel-cable 3, and avoid skidding, safety is good.
