This elevator weight adjustment device further comprises drawing liquid pipeline and the infusion pump that connects liquid storage pool and priming device, and liquid storage pool, drawing liquid pipeline and infusion pump are formed pumping device.Infusion pump is pumped recycle to the fluid injection case of priming device with the liquid in the liquid storage pool by the drawing liquid pipeline.
Lift car and counterweight are suspended on the both sides of traction sheave respectively, and keep certain state of equilibrium, the passenger reduces in lift car, car one amount of stressing alleviates, car one side and counterweight one side balance have between the two been broken, weight sensor detects the variation of weight and sends signal, the liquid-filling valve of control priming device is opened, by the equilibrium liquid case on fluid injection pipeline and the liquid-filling valve injection car, the injection certain quantity of fluid makes between car one side and counterweight one side and restores balance again with liquid in the fluid injection case.The passenger increases in lift car, car one amount of stressing increases, car one side and counterweight one side balance have between the two been broken, weight sensor then sends the tapping valve of signal control pumping equipment and opens, by leakage fluid dram certain quantity of fluid is discharged, make between car one side and counterweight one side to restore balance again.The liquid of discharging flows into liquid storage pool, is transported in the fluid injection case of priming device by liquid suction pipe by the infusion pump effect.
The weight of the counterweight in the elevator weight adjustment device of the present invention can be provided with fixing preset value according to actual needs, then can utilize weight sensor to detect the changes in weight of lift car, with detected value and preset value contrast, can take to operate to keep the both sides balance accordingly.
Be compared with the prior art, the present invention has following characteristics:
By changing the liquid capacity in the equilibrium liquid case, the weight of cage side is maintained in the fixed range, thereby make between car one side and counterweight one side and keep weight balancing, make the motor power consumption reduce greatly, the equilibrium liquid case is contained on the lift car simultaneously, significantly reduced taking of hoistway space, and the increase of car weight helps reducing the vibration in the car, raising passenger comfort.
[description of drawings]
Fig. 1 is the scheme drawing of elevator weight adjustment device of the present invention.
[specific embodiment]
See also Fig. 1, the scheme drawing of elevator weight adjustment device of the present invention, the car 5 of diagram towed elevator is connected by steel rope 2 with counterweight 8 and hangs on traction sheave 1 both sides, and traction motor drives traction sheave 1, utilizes friction force drive car 5 up-and-down movements of 1 of steel rope 2 and traction sheave.
The diagram elevator weight adjustment device comprises priming device, pumping equipment, pumping device, weight sensor 6, and is arranged on the equilibrium liquid case 3 on the car 5.Weight sensor 6 is arranged on lift car 5 bottoms, and the weight sensor signal connects priming device and pumping equipment.
This priming device comprises fluid injection case 14, fluid injection pipeline 15 and liquid-filling valve 16, fluid injection pipeline 15 extends and each floor and corresponding equilibrium liquid case 3, and liquid-filling valve 16 all is set at each floor, weight sensor detects the variation of weight and sends signal, the liquid-filling valve 16 of the priming device of this floor of control elevator place is opened, and fluid injection case 14 interior liquid then pass through the spout of the fluid injection pipeline 15 of this floor and inject in the equilibrium liquid case 3.
On this equilibrium liquid case 3 pumping equipment is housed, this pumping equipment comprises the tapping valve 4 that is installed on the equilibrium liquid case 3.Weight sensor detects the variation of weight and sends signal, and the tapping valve 4 of control pumping equipment is opened, and liquid is discharged in the equilibrium liquid case 3.
This pumping device comprises liquid storage pool 9, infusion pump 10 and drawing liquid pipeline 12, and the leakage fluid dram of pumping equipment is aimed at liquid storage pool 9, and the liquid of discharge falls into liquid storage pool 9, and recycles in drawing liquid pipeline 12 flows into fluid injection case 14 again by infusion pump 10.
Elevator arrives the braking of a certain floor stop after, passenger's car 5 of coming in and going out, this moment, car 5 weight changed, weight balancing between car one side and counterweight one side is broken, the both sides overbalance, at this moment weight sensor sends signal, control priming device and pumping equipment action.
Less than counterweight one amount of stressing, the liquid-filling valve 16 of priming device is opened as car one amount of stressing, and liquid injects in the equilibrium liquid case 3, car one amount of stressing increases, when detecting car one side and equate with counterweight one amount of stressing, liquid-filling valve 16 is closed, and this process pumping equipment is failure to actuate.
Greater than counterweight one amount of stressing, the tapping valve 4 of pumping equipment is opened as car one amount of stressing, and liquid is discharged in the equilibrium liquid case 3, car 5 weight reduce, when detecting being equal in weight of car one side and counterweight one side, tapping valve 4 is closed, and this process priming device is failure to actuate.
The liquid that tapping valve 4 is discharged falls into liquid storage pool 9, and by the fluid injection case 14 that infusion pump 10 is sent the top back to by drawing liquid pipeline 12, fluid injection case 14 links to each other with fluid injection pipeline 15.
Control system wherein adopts the general purpose control technology.
So, behind the passenger, the weight of car one side and counterweight one side is kept balance to elevator about in the of every layer, energy consumption minimum during the motor operation.And owing to increased the weight of car one side, the weight of car one side has increased relatively when the car undercapacity, and the external force acceleration/accel that disturbance causes to car reduces relatively, and car one side anti-vibration performance improves relatively.
