Problems solved by technology

[0002] At present, the counterweight of the elevator basically adopts solid counterweight. In most cases, the mass imbalance between the car side and the counterweight side requires the traction machine to provide a large traction force. Traction, this counterweight method makes the elevator consume a lot of power

Embodiment 1

[0040] like image 3 As shown, the elevator system has a car 3, a counterweight 4, a liquid tank 1 arranged below the car, a liquid tank 2 arranged below the counterweight, a liquid pipe device 11 connecting the two liquid tanks, a car liquid tank The valve device 9 configured in the liquid tank, the liquid height sensing device 5 in the liquid tank, the car weighing device 6, the car frame 8, the auxiliary hydraulic pump 13 placed in the hoistway, the connecting pipe device 12 between the auxiliary hydraulic pump and the rubber liquid tank , Car hydraulic tank auxiliary valve device 10.

[0041] Assuming that the rated load capacity of the car is 900kg, the weight of the flowable liquid in the car liquid tank and the counterweight liquid tank is 450kg. The auxiliary hydraulic pump can accommodate 1Wkg of liquid (it needs to be calculated and determined according to the actual mechanical design of the hydraulic pump resistance, etc., and it is set as a constant at this time)....

Embodiment 2

[0048] like Figure 4 As shown, the elevator system has a car 3, a counterweight 4, a liquid tank 1 arranged below the car, a liquid tank 2 arranged below the counterweight, a liquid pipe device 11 connecting the two liquid tanks, a car liquid tank The valve device 9 configured in the liquid tank, the liquid height sensing device 5 in the liquid tank, the car weighing device 6, the car frame 8, the auxiliary hydraulic pump 13 placed in the hoistway, the connecting pipe device 12 between the auxiliary hydraulic pump and the rubber liquid tank , Car hydraulic tank auxiliary valve device 10.

[0049] Assuming that the rated load capacity of the car is 900kg, the weight of the flowable liquid in the car liquid tank and the counterweight liquid tank is 450kg. The auxiliary hydraulic pump can accommodate liquid Wkg (it needs to be calculated and determined according to the resistance of the hydraulic pump after the actual mechanical design, and it is set as a constant at this time)...

Abstract

The invention discloses an elevator with adjustable liquid counter weight and a control method thereof. Liquid tanks are arranged under a lift car side and a counter weight side, and a control device is adopted for controlling the liquid flowing between the two liquid tanks. The elevator and the control method have the advantages that the output power of a dragging machine can be reduced, and the electric power is saved.

Description

technical field [0001] The invention relates to an elevator and a control method thereof. Background technique [0002] At present, the counterweight of the elevator basically adopts solid counterweight. In most cases, the mass imbalance between the car side and the counterweight side requires the traction machine to provide a large traction force. Traction, this method of counterweight makes the elevator consume a lot of power. The traction requirements for the traction machine are also very high. [0003] Today, when the level of hydraulic technology has been significantly improved, there is also a technical basis for applying the method of liquid counterweight and hydraulic control to the elevator system. Contents of the invention [0004] The invention provides an elevator with a liquid-adjustable counterweight, which can reduce the output power of a traction machine and save electricity. [0005] In order to solve the above technical problems, the present invention...
