Description
The invention relates to an unpowered elevator with adjustable counterweight weight, belonging to the technical field of machinery manufacturing and hoisting equipment manufacturing.
Background
In modern cities, high buildings stand in forest, the elevator is visible everywhere, and people can not drive the elevator in life; elevators in the prior art are all driven by motors, the motors inevitably consume electric energy when running, for example, a high-rise elevator with the load of 1000KG, a 20KW motor continuously runs 12 hours a day and needs to consume 12 × 20=240KWH electric energy; the elevator in the prior art consumes energy, and the elevator cannot run without electricity; when power failure occurs, the elevator cannot be lifted or lowered when stopping midway, and a plurality of safety problems can be caused; because of these problems, it is desirable to have an elevator that can operate reliably at any time without consuming power, and the unpowered elevator with an adjustable counterweight weight of the present invention can meet this requirement without consuming power, and therefore operates as usual in the event of a power failure.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide an unpowered elevator.
In order to solve the technical problems, the invention provides the following technical scheme:
the invention provides an unpowered elevator with adjustable counterweight weight, which comprises: the system comprises a lift car, a counterweight water tank, a fixed pulley, a brake drum, a steel wire rope, a band-type brake, a continuously variable transmission, a water pump and a circulating water pipeline system;
the upper end of the lift car is connected with a steel wire rope, the steel wire rope is wound on a brake drum fixed in the center of the top of the lift shaft through a fixed pulley fixed on the top of the lift shaft, and the brake drum is wound with a plurality of circles of steel wire ropes and then connected with a balance weight through a fixed pulley; the rotating shaft of the brake roller is connected with an input shaft of a continuously variable transmission (the continuously variable transmission can adopt another invention of the inventor, namely a pagoda type variable diameter gear continuously variable transmission), an output shaft of the continuously variable transmission is connected with a water pump, and the water pump is used for pumping water in the water pool at the bottom of the building to a water tank at the top of the building; the length of the steel wire rope ensures that the counterweight is at the highest floor when the elevator car is at the lowest floor; if the weight of the counterweight is equal to that of the lift car, the driving force is zero, and the lift car and the counterweight are static; if the weight of the lift car is larger than that of the counterweight, the lift car descends, and the counterweight ascends; if the weight of the counterweight is greater than the weight of the car, the counterweight descends and the car ascends.
The method for adjusting the weight of the counterweight is as follows: the counterweight is a water tank with an opening on the top and a water drain valve on the bottom; a water pipe is arranged on the side wall of the elevator shaft, a water outlet and an electric control valve are arranged on each floor of the water pipe, and a remote control valve is arranged at the bottom of the counterweight water tank; when the weight of the counterweight needs to be increased, the lift car stops at which floor, and the electric control valve of the floor is controlled to inject water into the water tank; when the weight of the counterweight needs to be reduced, remotely controlling a remote control valve in the water tank at any time, and discharging water to a pool below the vertical shaft; therefore, when the weight of the counterweight needs to be adjusted after the weight of the elevator car and the counterweight and the position of the elevator car and the counterweight are detected by the elevator detection and control system, the weight of the counterweight can be adjusted at any time by injecting water or discharging water.
For example, when the lift car stops at the bottommost layer, the lift car is ready to fully load and ascend, the system detects that the weight of the lift car is 2500KG and the weight of the counterweight is 1500KG, then the weight of the counterweight must be adjusted to be larger than the weight of the lift car, then an electric control valve for controlling the side wall of the lift shaft at the topmost layer injects water into a counterweight water tank, the upper part of the counterweight water tank is open, and the angle of a water injection port of a water pipe enables water flow to be injected into the water tank; when the weight of the counter weight is larger than that of the lift car after water injection, the band-type brake is released, the counter weight begins to descend, and the lift car begins to ascend; if passengers get on or off midway, when the weight of the lift car and the weight of the counterweight deviates, the counterweight weight is certainly larger than the weight of the lift car, water drainage is not needed at the moment, the transmission ratio of the continuously variable transmission can be adjusted to change the rotating speed of the water pump, and the running speed of the lift car is adjusted by using the resistance change generated by the power change of the water pump; after the lift car reaches the top floor, if the lift car is fully loaded and descends, the counterweight at the lowest floor needs a small amount of water to be discharged to be lower than the weight of the lift car; after the lift car descends, if passengers get on or off midway, the counterweight water tank needs to be drained at any time until the weight of the lift car is smaller than that of the lift car under the condition that the weight of the lift car is lower than that of the counterweight, and if the weight of the lift car is larger than that of the counterweight and the weight difference is large, the counterweight water tank does not need to be filled with water at the moment, and the power of the water pump can be adjusted to control the running speed of the lift car; if the lift car descends at the topmost layer in an idle load mode, the water needs to be discharged to a position lower than the weight of the lift car from the counterweight water tank at the bottommost layer, after the lift car descends, if passengers get on the lift car midway, the counterweight water tank does not need to be filled with water, and the power of a water pump can be adjusted to control the running speed of the lift car; the brake band-type brake is used for braking the brake roller, and is mainly used for locking the brake roller when the car stops, so that the car cannot move up and down from a safety angle; the water pump is coaxial with the brake roller, and the brake roller drives the water pump to pump water to the roof water tank when rotating up and down along with the lift car; when the weight difference between the lift car and the counterweight is large, so that the running speed of the lift car is high, the water pump is started to pump water and decelerate the running of the lift car; therefore, as long as water exists in the roof water tank, the elevator can run all the time, most of water consumed in the running of the elevator is circularly lifted to the roof water tank through the water pump of the elevator, and insufficient water can be supplemented through rainwater or tap water, so that the elevator can be completely free of power consumption, energy-saving, environment-friendly and safe.
The invention has the following beneficial effects:
the elevator adopting the technical scheme has the most remarkable beneficial effects of energy conservation, the elevator in the prior art takes the elevator with the largest reserved load of 1000KG as an example, the power of a driving motor is 18.5 or 22KW, the driving motor is calculated according to 20KW, the elevator continuously runs for 12 hours every day on average, and the consumed electric energy is 240 degrees; according to the data record: by the end of 2015 years, 1500 ten thousand elevators are reserved all over the world, and 425.96 are reserved in Chinese elevators; 1500 ten thousand elevators consumed 36 hundred million degrees of electrical energy per day;
425.96 ten thousand elevators consume 10.2 hundred million degrees of power per day. When the annual generated energy of the three gorges hydropower stations is 870 hundred million kilowatts, the daily generated energy is 2.38 hundred million degrees, which is equivalent to that 4.3 three gorges hydropower stations can meet the electricity consumption of 425.96 ten thousand elevators in China; if the elevators all adopt the technology of the invention, 4 three gorges hydropower stations are equivalently added by space; and the counterweight weight-adjustable unpowered elevator runs as usual when power is cut because of no power consumption, thereby solving the trouble when the elevator in the prior art is powered off.
