Abstract
The utility model discloses a counterweight adjusting mechanism which is capable of improving efficiency of an elevator. The counterweight adjusting mechanism comprises a frame and a drag rope which connects an elevator cage and the counterweight. The frame is provided with a rotating shaft, a first lever and a second lever. One end of the first lever and one end of the second lever are respectively rotatably connected with the rotating shaft, and the other ends are respectively connected with a stress applying mechanism arranged on the frame; a traveling block and an electromagnet subassembly, on which the drag rope is wound, are arranged below the first lever and the second lever; the traveling block is in lapping joint with the first lever and the second lever; the electromagnet subassembly is connected at the lower end of a transmission rod; and the upper end of the transmission rod is hinged with the first lever through a pin roll. The counterweight adjusting mechanism is reasonable in design, simple in structure and reliable in work, and can reduce requirement on output torque of the motor, save material, reduce making cost of the elevator and save energy. The bigger the rated load of the elevator is, the more obvious of the advantages of the counterweight adjusting mechanism are.
Description
Technical field
The utility model relates to a kind of elevator counterweight equipment, particularly a kind of counterweight adjusting mechanism that improves elevator energy efficiency.
Background technology
At present, the domestic elevator for people of taking advantage of adopts suspension than the dragging system that is 2: 1 mostly.Traction sheave can positive and negatively be rotated by motor-driven, drags car 1 up-and-down movement by steel rope.
China's elevator industry standard code elevator counterweight coefficient is 0.4～0.5.Because taking advantage of elevator for people capacity weight (taking advantage of number) is random variation.If payload ratings is G, counterweight is G
p, when nobody (zero load) capacity weight of taking the opportunity is 0, at full load is G.With counterweight G
pIt is more rational being defined as 0.4～0.5G (near intermediate value).For ease of analyzing contrast, we get counterweight G
p=0.5G.
In fact, when counterweight is set, also to consider car deadweight G
1, i.e. counterweight G
P2=G
P+ G
1Can make car deadweight G like this
1Fallen by the counterweight complete equilibrium, no longer produce load moment, do not increase the motor burden.But the weight of counterweight has increased greatly.In addition, the output torque to motor also has higher requirement:
As payload ratings G=1000Kg, its car deadweight G
1=1200～1500Kg,
Its counterweight G
P2=0.5G+G
1=500+ (1200～1500)=1700～2000 (Kg),
Then, motor output torque
The utility model content
The purpose of this utility model is the deficiency that exists at prior art, a kind of simple in structure, reliable operation is provided, can reduces the requirement of motor output torque, saves the counterweight adjusting mechanism of the improved elevator energy efficiency of the raw MAT'L and the energy.
The technical solution of the utility model is: a kind of counterweight adjusting mechanism that improves elevator energy efficiency, comprise framework and hauling rope, one end of described hauling rope connects car by traction sheave, the other end connects balance weight body by track adjusting wheel, it is characterized in that: described framework is provided with rotating shaft, a lever and No. two levers, one end of a lever and No. two levers is rotationally connected with rotating shaft respectively, its other end respectively be arranged on framework on boosting mechanism be connected; The below of a described lever and No. two levers is provided with movable pulley and the electromagnet assembly that is wound with described hauling rope, movable pulley and a lever and No. two lever overlap joints, electromagnet assembly connects the lower end of drive link, and the upper end of drive link is hinged by bearing pin and a lever.
The utility model compared with prior art has the following advantages:
(1) the utility model is reasonable in design, and is simple in structure, and reliable working performance can make the motor output torque reduce 1/3, and the towing machine cost reduces by 20%, saves electric energy 1/3;
(2) reducing balance weight body, save raw MAT'L, is example with nominal payload G=1000kg, and counterweight can reduce 700kg, and the cast iron price can reduce elevator manufacturing cost 700 * 7=4900 unit by 7.0 yuan/Kg;
(3) the elevator payload ratings is big more, and effect of the present utility model is remarkable more.
Description of drawings

The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, the utility model comprises framework 1 and hauling rope 12, one end of described hauling rope 12 connects car by traction sheave 13, the other end connects balance weight body by track adjusting wheel 14, described framework 1 is provided with rotating shaft 6, a lever 2 and No. two levers 9, one end of a lever 2 and No. two levers 9 is rotationally connected with rotating shaft 6 respectively, its other end respectively be arranged on framework 1 on boosting mechanism be connected; The below of a described lever 2 and No. two levers 9 is provided with movable pulley 8 and the electromagnet assembly 3 that is wound with described hauling rope 12, movable pulley 8 and a lever 2 and No. two lever 9 overlap joints, electromagnet assembly 3 connects the lower end of drive link 11, and the upper end of drive link 11 is hinged by bearing pin 4 and a lever 2.
Described boosting mechanism includes spring 15, and the lower end of spring 15 is connected with base 17, and its upper end is connected with pull bar 10, and the upper end of pull bar 10 and a lever 2 or No. two levers 9 are hinged.
During the utility model work, for elevator counterweight has increased a variable auxiliary force G
f, can be when needing with G
fAdd, can make G when not required
f=0; Above-mentioned functions is that it helps adjusting the moment that capacity weight produces, and reduces the requirement to the motor output torque, reaches the purpose of economize on electricity by the exerting pressure and loosen realization of the 2 pairs of movable pulleys 8 of a lever that are connected with boosting mechanism with electromagnet assembly 3.
The utility model also can produce a unmodified subsidiary load G
F1, be used to share a part of counterweight load, reduce the weight (deadweight of elevator) of counterweight, reduce the elevator manufacturing cost.This function is to produce by exerting pressure of the 9 pairs of movable pulleys 8 of No. two levers that are connected with boosting mechanism.
