Abstract
The utility model relates to an explosion proof variable frequency and voltage speed-adjusting elevator tractor, which is characterized in that a coder is arranged on an output shaft of a variable frequency speed-adjusting motor, the motor and the coder are all provided with explosion suppression boxes, the box faces are shared, the outer sides of the explosion suppression boxes are connected with a brake by a motor shaft, and a brake switch is arranged at the outer sides of the explosion suppression boxes; an encapsulation junction box and an encapsulation winding are arranged on the brake. The utility model adopts frequency control, the rotation speed of the motor is changed by electric frequency to carry out speed regulation without a step, and operation is comfortable. Because a brake is contracted after an elevator stops, the utility model basically does not have friction, so heat can not be generated, and meanwhile, the switch has the function of protection to cause the utility model to be not ineffective.
Description
Technical field: the utility model relates to the elevator technology field, belongs to the towing machine of elevator specifically, is widely used in explosion hazard area.
Background technology: traditional explosion-proof traction machine adopts the AC double-speed elevator towing machine, it is step speed regulation, so have that the elevator ride comfort is poor, energy consumption is big and many shortcomings such as volume heaviness, the explosion-proof lift towing machine adopts the inside brake form simultaneously, and elevator uses the brake collar wearing and tearing that with the passing of time will cause on the drg, thereby causes brake clearance to increase, for this reason the gap of necessary regulating brake, then motor must be taken apart and carry out regulating brake, bring very big inconvenience to maintaining.
Summary of the invention: the purpose of this utility model provides a kind of can the use at explosion hazard area, and move comfortable, the flame-proof converter variable voltage speed control elevator traction machine that volume is little and easy to maintenance.
For finishing the technical scheme that above-mentioned purpose is taked: the elevator rotary encoder is set on the shaft of the adjustable speed-adjustable asynchronous motor of explosion-proof frequency conversion, described motor is provided with Flameproof box, the coder Flameproof box is set described coder and motor Flameproof box face is shared, the Flameproof box outside connects the elevator traction drg by motor shaft, above-mentioned drg is provided with brake switch, is provided with on the drg to water to establish in the envelope connection box to water the envelope coil.
Electrical motor of the present utility model adopts variable-frequency control asynchronous motor; change the rotating speed of electrical motor by the frequency of electricity; play infinite speed variation so the elevator operation is comfortable; advantage of low energy consumption; drg of the present utility model adopts outer braking model; regulating brake is simple and convenient; adopt frequency control simultaneously; elevator brake is an ability band-type brake after elevator reaches zero-speed; basically there is not friction; so can not produce heat, on drg, a brake switch is set in addition, this switch has played protective effect; when elevator machine brake can't open for a certain reason; switch is failure to actuate, and elevator control cabinet is not received on-off signal, just can cut off motor current immediately; prevent owing to drg does not open the high temperature that produces between the brake collar that causes and the brake wheel.
Description of drawings:
Fig. 1 is the utility model constructional drawing.
The specific embodiment: the utility model is to adopt the adjustable speed-adjustable asynchronous motor 4 of explosion-proof frequency conversion according to motor shown in Figure 1; elevator rotary encoder 3 is set on the shaft of its motor 4; described motor 4 is provided with Flameproof box; it is shared with motor Flameproof box face that described coder 3 is provided with coder Flameproof box 2; the outside of motor Flameproof box connects the moving drg 11 of elevator traction by the axle of motor 4; above-mentioned drg 11 is provided with brake switch 5; brake switch can't open in the time of playing protection elevator traction machine et out of order and be failure to actuate; be provided with on the drg 11 and water envelope connection box 7; in establish water fill out the envelope coil 6, play explosion-proof.
Can take turns 1 the shaft end terminal pad driver that goes out of motor 4 according to above-mentioned setting, when et out of order, can rotate the cab that jiggering is sling or put down elevator with handwheel 1.The other end of described motor 4 is provided with the change speed gear box 9 of change-speed box.
Again according on the above-mentioned basis, the steel wire hoist ropes 10 on traction rope sheave 8 and the traction rope sheave is set on the axle of motor 4, hoist ropes 10 is connected with cab to be used for lifting by crane and puts down cab usefulness.
Claims (3)
1, a kind of by motor, coil, traction sheave and hoist ropes, the flame-proof converter variable voltage speed control elevator traction machine that change speed gear box and handwheel are formed, it is characterized in that on the shaft of the adjustable speed-adjustable asynchronous motor of explosion-proof frequency conversion (4) elevator rotary encoder (3) being set, described motor (4) is provided with Flameproof box, it is shared with motor Flameproof box face that described coder (3) is provided with coder Flameproof box (2), the Flameproof box outside connects elevator traction drg (11) by motor shaft, above-mentioned drg (11) is provided with brake switch (5), and drg (11) is gone up to be provided with to water to establish in the envelope connection box (7) and watered envelope coil (6).
