Description
Technical field
The utility model relates to a kind of lift appliance, particularly the closed bonded assembly elevator of counterweight and storing box adjustable type counterweight.
Background technology
In towed elevator, car and counterweight hang on the traction sheave both sides, and traction sheave is by direct motor drive.Car is used to transport passenger or goods, and weight and part elevator load weight that counterweight can the balance car reduce the loss of motor power (output).The weight of counterweight is changeless in actual applications, and when the changes in weight of people in the car or goods, the horsepower output of elevator motor will change, and drives the operation up and down of lift car to guarantee the enough power of output.Like this, the power of electric motor of elevator must be enough big, making when loading maximum load in the car can trouble-free operation, different elevator load carrying ability correspondences the electrical motor of different capacity, for elevator manufacturing enterprise, just must use the electrical motor of various power requirements to produce the elevator of different load carrying abilities.
China utility model patent ZL200520033646.6 discloses a kind of adjustable Elevator weight sensor device, counterweight is by to loaded van, form heavy ball and the storage bin that is distributed in each layer, the counterweight napiform root rolls at storage bin and between to loaded van according to the variation of weight in the car, make counterweight and car reach steady, the power that drives the electrical motor output of elevator like this will be smaller, makes the power consumption of electrical motor reduce.In this patent, be to rely on gravity rolling to heavy ball, when the weight of the load carrying ability of elevator and counterweight differs big, from the storage bin that is distributed in each layer, be rolled to longer to heavy ball to the time that needs in the loaded van to spend, after need waiting for counterweight and car balance, the passenger who takes elevator in car just can bring into operation, all need the situation passenger who stops the trapeziodal modulation joint to lose patience for every floor, produce the mood of anxiety.
Japan publication spy opens 2000335850 and discloses a kind of elevator balanced formula counterweight, it can be according to the variation of weight in the car, extracting liquid out from liquid storage tank after, the fixing position of well headroom is injected in the counterweight in-to-in water tank, below hoistway fixing position from counterweight in-to-in water tank discharged liquid in liquid storage tank, to reach the weight balancing between car and the counterweight, the feasible moment of torsion that drives the electrical motor of elevator reduces, thereby reduce the motor power (output) that elevator uses, realize that small power motor drives the heavy elevator, reaches the purpose of energy savings.This invention weak point is that the position of injection or discharged liquid is fixed, the injection phase is the well headroom of elevator, the position of discharged liquid is the bottom of hoistway, the weight that in the operation overall process of elevator, can only could regulate counterweight like this in well headroom and two positions of pit, cause at midway location and can't regulate, and midway location belongs to most positions of elevator operation, and in other words, this counterweight regulation scheme can only use a few locations at elevator.In addition, inject in this invention and discharged liquid be by means of the similar water tap device, finish at an open circulation loop, liquid spills when mobile between counterweight in-to-in water tank and liquid storage tank easily, thereby causes the pollution to environment.
Summary of the invention
The purpose of this utility model is at the deficiencies in the prior art, and a kind of elevator adjustable type counterweight is provided, and it can regulate the weight of counterweight according to the variation of lift car weight.
For achieving the above object, the utility model is by the following technical solutions: elevator adjustable type counterweight, comprise memory type counterweight, storing box, flowing material and the control setup of between memory type counterweight and storing box, carrying in order to the control flowing material, it is characterized in that, be connected to form the closed loop of flowing material between described memory type counterweight and the storing box by delivery duct, and described control setup is arranged in this closed loop.This flowing material is liquid such as water, or powder, or the solid matter that flows easily.
Above-mentioned delivery duct by be connected first delivery duct between memory type counterweight discharge orifice and the storing box inlet and be connected the storing box discharge orifice and memory type counterweight inlet between second delivery duct form.
Lower position when above-mentioned storing box is positioned at the memory type counterweight and moves to lowest positions.
Above-mentioned storing box is positioned at memory type counterweight running route.
Above-mentioned control setup is made up of with the injection device that is arranged on second delivery duct the electromagnetic valve that is arranged in first delivery duct.
Above-mentioned control setup is made up of with the injection device that is arranged on second delivery duct the pump that is arranged in first delivery duct.
The actual weight of above-mentioned memory type counterweight and car is unequal, and side's weight of operation is greater than a side who upwards moves downwards.
Above-mentioned memory type counterweight equates with the actual weight of car.
The utility model is owing to adopted said structure, after passenger in lift car or goods turnover are finished or in the turnover process, can regulate the weight of counterweight according to the actual weight of lift car, be not subjected to the influence of elevator load amount, saved power of electric motor to greatest extent; And by plumbing connection, do not have spilling of fluid when counterweight is regulated, can not cause pollution environment.The flowing velocity of fluid is very fast, is easier at the weight adjusting time ratio that carries out counterweight, avoids the passenger to lose patience, produce the mood of anxiety because of waiting time is long.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is done to describe in further detail.
Fig. 1 is the scheme drawing of embodiment 1;
