Abstract
The invention discloses an unlined elevator with a magnetic balance mechanism, which relates to the field of unlined elevators. The unlined elevator comprises a vertical shaft, a car and a brake, wherein a fixed beam is fixed on the inner wall of the vertical shaft; the outer side of the car is provided with a car bracket; a permanent magnet linear motor is arranged between the fixed beam and the car; and a magnetic balance mechanism is arranged between the fixed beam and the car bracket. Using the technical proposal of the invention, when the car deviates to one side due to the unbalanced pressure caused by working air gap variations of the linear motor, the magnetic balance mechanism generates resistance to inhibit the car to deviate, thereby dynamically balancing and eliminating the unbalanced pressure on the car due to the working air gap variations of the linear motor, being beneficial to locating the car in a track and ensuring the smooth running of the car in the track; and the invention reduces the frictional resistance between the car and the track and increases the actual load of the car.
Description
Technical field
The invention belongs to wireless elevator field, be specifically related to a kind of wireless elevator that has magnetic balanced mechanism.
Background technology
Gig or elevator are the important transportation links of mine and all kinds of buildings, in common elevator system, hoisting way is known, promote the used structure of elevator, be the top that the Machine Room is installed in elevator, the rotating machine head roll, steel rope one end that is wrapped on the cylinder is connected in car, and the other end is connected in a counterweight.And super-high buildings many for personnel, that load is big and super dark mine, needing the traffic transport process ability of high level, elevator to take a large amount of spaces and traffic capacity low then is serious problems.
In order to overcome the problems referred to above, do not require that the wireless linear motor elevator of steel rope and independent Machine Room can be used as a kind of method that improves the elevator traffic capacity, proposed for a long time.This wireless elevator mainly contains line inductance electromotor and two kinds of drive configuration types of permanent-magnetism linear motor, and wherein energy index height, the working gas gap of permanent-magnetism linear motor are wide, thrust is big, are acknowledged as the only drive source of linear motor elevator.Owing to exist 5～10 times of bigger indigenous laws to normal hoisting force between permanent-magnetism linear motor elementary and secondary to attractive force, present employing both sides working gas gap is identical, the double-flanged end permanent-magnetism linear motor structure of face-to-face layout, so that offset normal direction attractive force each other, alleviate car inclination positive pressure, reduce the friction of motion resistance, increase capacity weight.The elementary pit shaft inboard that is separately fixed at of two permanent-magnetism linear motors, secondary fixed when elementary energising formation travelling-magnetic-field, thereby produce hoisting force upwards in the car both sides, drive secondary and car movement.
But the ideal structure of above-mentioned linear motor elevator, only solve basic driver power problem, but do not solve real-world operation engineering key application problem, as the processing of motor and track, arrange that the working gas gap on the double-flanged end linear electric motors both sides that unfairness brings is different, car bears very big side direction positive pressure and to a side skew back.
Such as, originally ideal operation air gap in both sides is the linear motor elevator of the bilateral layout load-carrying of 5mm: 5mm 1000kg, and because of working gas gap is identical, both sides normal force equal and opposite in direction, direction are cancelled out each other mutually on the contrary, and desirable overbalance skew back positive pressure is 0.But in operational process, certain factor causes the working gas gap on any one side to reduce 1mm respectively, 2mm, 3mm, make the working gas gap on both sides be changed to 4mm: 6mm respectively, 3mm: 7mm, 2mm: during 8mm, one side normal force that air gap is little becomes big, one side normal force that air gap is big diminishes, both can not offset, car will be subjected at least 2.5 tons respectively, 5 tons, 8 tons overbalance skew back positive pressure, car is inhaled inclination is taken place to the little side of air gap, simultaneously, pressing coefficient of rolling friction 0.04 calculates, this positive pressure also will bring 100kg respectively, 200kg, the friction drag of 320kg, make the actual load-carrying of elevator be reduced to 900kg respectively by original 1000kg, 800kg, 680kg reduces 10% respectively, 20%, 32%.
In the running process of elevator, the machine operation air gap changes more greatly, and this overbalance skew back positive pressure is big more, and direct ratio increases with the increase of elevator dead-weight capacity.Therefore, causing moving friction drag increases, and effectively lifting load reduces, and moves not steady, speed is low, and noise is big, installation and processing accuracy requirement height, construction costs and operating cost height, the elevator location difficulty, even registration device lost efficacy, car blocks, holds a series of problems such as can't move.Thereby, can not be applied in practice.
Summary of the invention
The technical problem to be solved in the present invention is wireless lift car location difficulty, the problem that operation is not steadily, capacity weight is little, the wireless elevator that has magnetic balanced mechanism that provide a kind of and locate accurately, operates steadily, capacity weight is big.
