Abstract
The invention discloses a liner motor arranging method for a cordless elevator. Two U-shaped liner motors with bilateral structures are used as drive sources of an elevator and arranged at one side or two sides of a car to form a cordless elevator in a knapsack type or balance type structure. An included angle between the axes of the two U-shaped liner motors can be any angle between 0 degree and 360 degrees, and upper and lower air gaps of the U-shaped liner motors have the formula that g1 is smaller than or equal to g2. By adopting the motor arranging method provided by the invention, the double U-shaped permanent magnet liner motors inhibit normal attraction borne by the moving part of the elevator, reduce the mechanical strength of an installation base, a car and a positioning and braking device of the cordless elevator and the weight of the moving part of the elevator and increase effective loads. In addition, a smaller part of unbalanced normal attraction can be retained, the problem of side inclination of the knapsack type car can be effectively solved, and the stability of the air gaps in the running process of the motors can be kept.
Description
Technical field
The invention belongs to wireless lifting field, be specifically related to a kind of linear electric motors method for arranging that is used for wireless elevator.
Background technology
Elevator or gig are the important transportation links of mine and all kinds of buildings, in common elevator system, hoisting way is known, the structure that gig is used, be the top that the Machine Room is installed in gig, 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, gig 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 electric motors gig of steel rope and independent Machine Room can be used as a kind of method that improves the gig traffic capacity, proposed for a long time.This wireless gig 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 electric motors gig.From the prior art, for the elevator that adopts permanent-magnetism linear motor to drive, the type of motor is nothing more than single-side structural or bilateral symmetry structure, and the method for arranging of motor mainly contains " knapsack " formula structure that is arranged in car one side or the symmetrical structure that is arranged in the car both sides; On operation scheme, can adopt the short elementary length of moving pri secondary, the perhaps moving secondary elementary two kinds of arrangements of the secondary length of weak point, motor stator is fixed on the pit shaft inboard, mover is fixed on the car, when electric motor primary energising formation travelling-magnetic-field, thereby produce hoisting force upwards, drive car movement.
As Figure 1A, 1B with the single-side structural permanent-magnetism linear motor as drive source.Permanent-magnetism linear motor is arranged in a side of car, and motor stator part 1 is laid along basis 3 is installed, and mover part 2 links to each other with car 4.The motor method for arranging of employing shown in Figure 1A, 1B, exist huge indigenous law to attractive force between motor elementary and secondary, make car firmly be adsorbed on the orbit though can overcome gravity, avoided the inclination problem of car, but, huge normal direction suction certainly will require to strengthen installing the mechanical strength of basis, car, location and brake equipment, increase the weight of elevator motion part, cause bigger operation friction drag simultaneously, running noises is big, reduce capacity weight, cause construction costs and operating cost to increase.
Therefore, someone proposes to adopt that the both sides working gas gap is identical, the bilateral structure permanent-magnetism linear motor of face-to-face layout is as the drive source of elevator, so that offset normal direction attractive force each other, alleviate car inclination positive pressure, reduce the friction of motion resistance, increase capacity weight, as Fig. 2 A, 2B, 2C and shown in Figure 3.Adopt as Fig. 2 A, 2B, 2C and motor method for arranging shown in Figure 3, eliminated the suffered normal direction attractive force of electric mover part 2, but, can not overcome car inclination and deflection problem that the existence owing to car gravity and load over centre causes, will certainly cause in the running process of elevator air gap inequality up and down like this, influence the drive ability of motor.
Fig. 4 A, 4B, 4C have provided the elevator of the bilateral structure permanent-magnetism linear motor driving of adopting symmetric arrangement, promote the both sides that motor is symmetrically arranged in car, from theory, adopt motor method for arranging shown in Fig. 4 A, 4B, the 4C to eliminate the suffered most of normal direction suction of electric mover part 2, but the inclination of car and stressed problem still exist; The car of Fig. 4 A will bear the very big normal force in both sides and produce structural distortion arbitrarily, guarantee that the air gap of two bilateral structure permanent-magnetism linear motors equates also not a duck soup; Among Fig. 4 B, the 4C,, will certainly cause the change of another motor gas-gap, thereby make car still will bear no small overbalance normal force, make car generation inclination and deflection, influence the gig performance in case wherein the air gap of a motor changes.
The elevator that above-mentioned various employing permanent-magnetism linear motor drives on the method for arranging of motor, all more or less exists the intrinsic normal force of permanent-magnetism linear motor big, and inclination and deflection take place car easily, problems such as complex structure, location and operation difficulty.
Summary of the invention
The technical problem to be solved in the present invention is both to have suppressed indigenous law to greatest extent to the influence of attractive force to motor performance, keep a part of normal direction attractive force again and be used to overcome the car inclination problem that car gravity causes, the linear electric motors method for arranging that is used for wireless elevator of a side that a kind of drive motor is arranged in car, compact conformation, easy construction is provided.
