The reset of lead device, makes the pull rope of traction apparatus return to original state, waits next drawing-in motion.
At present, traction electric machine is replied control system and is mainly driven a sector wheel plate and matched by reset tension spring
The parts such as gear cup, magnet steel realize.This system structure is complicated, and in real work, frictional resistance is relatively big, easily occurs " no
Reply " problem, and number of parts is more, and production cost is higher.
Summary of the invention
It is an object of the invention to provide a kind of simple in construction, reliable in action, number of parts is few, production cost is low traction electricity
Control system replied by machine.
The technical scheme realizing the object of the invention is: a kind of traction electric machine replys control system, including screw gear, silk
Bar, baffle plate, return spring and block；Described screw gear is set to the wherein primary speed-down gear of traction electric machine, and and screw mandrel
Threaded；Described screw mandrel is fixed in the gear-box of traction electric machine；Described block is arranged on outside the stabilizer of traction electric machine
On wall；Described baffle plate is slidably connected with the rotating shaft of another reduction gearing of screw mandrel and traction electric machine, and baffle plate one end extends to gear
The lower section of block；Described return spring is enclosed within screw mandrel, and is positioned at above baffle plate.
The upper gear of described screw gear and the gear being engaged with are helical gear.
Control system replied by a kind of traction electric machine, also includes friction pulley, brake pad and stage clip；Described friction pulley is fixed on and leads
Draw on the wherein primary speed-down gear of motor；On the medial wall of the gear-box that described stage clip is fixed on traction electric machine；Described friction
In the rotating gear-box being fixed on traction electric machine in one end of block, the both sides of the other end of brake pad respectively with friction pulley and pressure
Spring contacts.
Have employed technique scheme, the present invention has a following beneficial effect: the screw gear of (1) present invention and screw mandrel
Threaded, during motor rotation, screw gear rises along screw mandrel, and baffle plate is pushed to top, completes drawing-in motion, motor stalling
Time, screw gear falls under the effect of return spring, it is achieved the reset of traction apparatus, simple in construction, reliable in action, number of parts
Less, easy to assembly, production cost is low.
(2) upper gear of the screw gear of the present invention and the gear that is engaged with are helical gear, make traction apparatus
Motion is more steadily reliable.
(3) brake pad of the present invention and friction pulley friction, makes the motion produced of replying of traction apparatus be not transferred to motor
Body, forms effectively protection to motor.
Accompanying drawing explanation
It is clearly understood to make present disclosure be easier to, below according to specific embodiment and combine accompanying drawing, right
The present invention is described in further detail, wherein
Fig. 1 is the structural representation of the present invention.
Being numbered in accompanying drawing:
