Abstract
The utility model discloses a counterweight weight automatic adjusting device of an elevator counterweight. A liquid storage box is arranged at the bottom of a car, a liquid storage box is arranged at the bottom of the counterweight, and the two liquid storage boxes are communicated with each other through a communication tube. A liquid pump is arranged on the communication tube close to the liquid storage box and communicated with a power supply through a controller. An actual load sensor is arranged in the car and electrically connected with the controller and transmits signals of actual load to the controller in real time. In operation process of an elevator, the counterweight weight automatic adjusting device enables the weight of the counterweight part to be equal to the sum of the weight of the car and the weight of the actual load in real time, namely balance of the weight between the two parts is kept, or the weight of a downlink part is led to be larger than that of an uplink part, the elevator constantly operates in a power generation state, and electricity generated by the elevator at the moment can be fed back to a power grid if an electricity feedback device is configured. Therefore, a motor of the elevator can work easily, electricity is saved, and the elevator operates smoothly.
Description
Technical field
The utility model relates to a kind of elevator of vertical lift, particularly a kind of counterweight weight automatic regulating apparatus of Elevator weight sensor.
Background technology
Counterweight is a component part of elevator drive system, and its effect is the weight of balance car.Be positioned at the another side of car, be connected on the sedan-chair top through traction steel-cable.Play energy-conserving action to focusing on elevator traction system, because Theoretical Calculation makes elevator load-carrying optimization before counterweight.The weight of counterweight equals the car deadweight and adds the half the of nominal load.
The Elevator weight sensor balanced system that also weighs, the radical function of this system is the relative equilibrium car weight, and the weight difference between car and counterweight is remained within the limit, guarantees that the traction transmission of elevator is normal.
If elevator is in operational process; If can guarantee that the weight of weight that car deadweight adds actual load and counterweight is identical or confirm weight change according to the direction of elevator prerun; Make elevator operate in generating state all the time, make car weight make car weight less than counterweight weight when promptly descending greater than counterweight weight with when up, can this moment when being equipped with electric energy feedback apparatus elevator electricity ability feedback grid; Then more can be energy-conservation, the traction transmission of elevator is more smooth and easy.And the counterweight that existing counterweight uses all is the solid counterweight, can't realize that the car deadweight in the operational process adds that the weight of actual load is identical with the weight of counterweight.
Summary of the invention
The purpose of the utility model is can't realize that in order to solve existing vertical lift elevator the car deadweight in the operational process adds that the weight of actual load is identical with the weight of counterweight; Perhaps make the weight of the weight of descender greater than ascender; Cause the motor power consumption greatly, problem of energy saving not, and provide a kind of energy-conservation, move the counterweight automatic regulating apparatus of Elevator weight sensor smoothly.
The utility model is to be provided with liquid reserve tank in the car bottom; Bottom at counterweight is provided with liquid reserve tank, is communicated with communicating pipe between two liquid reserve tanks, is provided with the liquid pump communicating pipe near liquid reserve tank; The liquid pump is communicated with power supply through controller; Be provided with the actual load sensor in the car, said actual load sensor is electrically connected with controller, and the actual load sensor is transferred to controller with the signal in real time of actual load.
Described counterweight top is provided with the solid counterweight.
The beneficial effect of the utility model is: in the operational process of elevator; The weight that makes counterweight weight partly equal car in real time adds the weight of actual load, promptly keeps the balance of two part weight or makes the weight of the weight of descender greater than ascender, makes elevator operate in generating state all the time; So; The motor of elevator can be worked like a cork, has saved electric energy, and operating ratio is more smooth and easy.
Description of drawings
Fig. 1 is the structure intention of the utility model embodiment.
The specific embodiment
See also shown in Figure 1; Be the embodiment of the utility model, it is to be provided with liquid reserve tank 11 in car 1 bottom, is provided with liquid reserve tank 21 in the bottom of counterweight 2; Between liquid reserve tank 11 and the liquid reserve tank 21 to be communicated with communicating pipe 3; Communicating pipe 3 near liquid reserve tank 11 or liquid reserve tank 21 is provided with liquid pump 4, and liquid pump 4 is communicated with power supply through controller 5, is provided with actual load sensor 6 in the car 1; Said actual load sensor 6 is electrically connected with controller 5, and actual load sensor 6 is transferred to controller 5 with the signal in real time of actual load.
Described counterweight 2 tops are provided with solid counterweight 22.
The working process and the principle of present embodiment are:
