For the present situation of above-mentioned prior art, the technical problem to be solved is in that to provide a kind of without counterweight, safety coefficient height, and applied widely and tunnel dimension requires the traction system of little screw type elevator.
This invention address that the technical scheme that above-mentioned technical problem adopts is: the traction system of the traction system of a kind of screw type elevator, including screw rod motor, movable pulley, support beam, car and two steel wire ropes, described screw rod motor is fixed on metope, the leading screw upper end of described screw rod motor connects support beam, lower end is unsettled, described movable pulley is placed in described support beam upper surface, described two steel wire ropes are symmetrically distributed in movable pulley both sides, ground is fixed in each steel wire rope one end, the other end hangs on movable pulley, described car and two steel wire ropes and is connected.
Further, described motor upper end is provided with patchboard, and described screw rod motor includes:
Motor housing；
Stator, is fixed in described shell；
Hollow rotor assembly, is rotatably connected in the center of described stator by rotating shaft；
Hollow axle ring flange, rear end cap, be respectively placed in motor housing both ends of the surface；
Cannon pinion, coordinates with key between described rotor combination；
Leading screw, is placed in described hollow rotor assembly center, threadeds with described hollow rotor assembly；
Linkage, coordinates with described hollow rotor assembly key；
Feed screw nut, is connected by screw formation linkage with linkage.
Further, described housing side is provided with encoder, and described encoder is secured by bolts in rear end cap, and described encoder is provided with the travelling gear engaged with cannon pinion.
Further, described linkage includes braked wheel and the mounting disc assembly being bolted with described braked wheel.
Further, described patchboard side is connected with brake.
Compared with prior art, it is an advantage of the current invention that: the present invention adopts and screw rod motor is fixed on wall, drive the collaborative leading screw of feed screw nut to move up and down by screw rod motor；This leading screw one end is unsettled, and the other end connects support beam, is provided above movable pulley supporting beam, and described movable pulley both sides arrange the steel wire rope connecting car, pass through guide screw movement, it is achieved drive the lifting of car.Leading screw displacement is the 1/2 of car displacement, in the situation that hoisting depth is identical, reduces the use length of leading screw, and then reduces production cost；It addition, adopt, braked wheel is set at hollow rotor component external, it is achieved leading screw and the self-locking of feed screw nut, when brake failure, still can provide safeguard, improve the safety coefficient of elevator；Meanwhile, the structure of the present invention, without counterweight, reduces hoistway space requirement.
