Drive under when meeting and engage with third gear 14, the deformation quantity of the first leaf spring 12 reaches maximum.
Under the collective effect of the first leaf spring 12 and third gear 14, the first swing rod 8 does not continue to swing, second gear 10
Position be fixed, first gear 6 starts to overcome the damping action of rotary damper 11 to drive second gear 10 and the second transmission
9 synchronous rotary of axis;Second gear 10 drives third gear 14 to rotate, and third gear 14 passes through the first rack gear 15, transmitting 16 and of item
Second rack gear 17 drives the rotation of the 4th gear 18, and reset spring 22 is stretched and energy storage;The direction of rotation of 4th gear 18 and the
The direction of rotation of one gear 6 is opposite;At this point, one-way clutch 19 does not play driving effect, the 4th gear 18 will not be by unidirectional
Clutch 19 and third transmission shaft 20 drive driven 26 synchronous rotary of delivery wheel;When the end of the first rack gear 15 and third gear 14
When engagement, third gear 14 continues rotation and can persistently stir the last one teeth of 15 end of the first rack gear, to make first
Rack gear 15 maintains the state, and the second rack gear 17 is still engaged with the 4th gear 18, and the deformation quantity of reset spring 22 reaches maximum.
At the same time, the electricity that active delivery wheel 7 drives winding to squeeze on it and by two contact rollers 32 by frictional force
Cable 39 conveys outward from cable disk 38, and cable 39 drives driven delivery wheel 26 to rotate and direction of rotation and active by frictional force
Delivery wheel 7 is on the contrary, driven delivery wheel 26 is opposite with coaxial 18 direction of rotation of the 4th gear;Due to one-way clutch 19 at this time
Driving effect is not played, so the rotation of driven delivery wheel 26 is not affected by the interference of the 4th coaxial gear 18, so that resetting bullet
The movement of the auxiliary conveying cable of the energy storage movement and driven delivery wheel 26 of spring 22 carries out simultaneously.
At the end of the cable 39 in 39 well of cable is laid with, Switching power, so that the output shaft of electrical drive module 24 is logical
Crossing the first transmission shaft 5 drives the slightly direction of first gear 6 to rotate very little angle, the active delivery wheel 7 of the first transmission shaft 5 it is reversed
Rotation can be ignored, and pulled 39 amplitude of cable of the reversion of active delivery wheel 7 is very small under this state, hardly to
The cable 39 of pull-out impacts;During 6 low-angle of first gear reversely rotates, first gear 6 passes through second gear
10, second driving shaft 9 and rotary damper 11 drive the first swing rod 8 to be swung up around the first transmission shaft 5;Reset spring 22 makes
Transmitting item 16 drives the beginning of the first rack gear 15 to engage with third gear 14, and the first rack gear 15 drives third gear 14 to rotate;At this point,
The direction of rotation of third gear 14 is identical as the reverse rotation direction of first gear 6, and second gear 10 is detached from rapidly third gear
14;Then it cuts off the power, the first gear 6 and active delivery wheel 7 being mounted on the first transmission shaft 5 are stopped rotating, and are actively conveyed
Wheel 7 no longer pulls the cable 39 on cable disk 38 to convey into 39 well of cable, and driven delivery wheel 26 stops rotating;In the first plate
Under the action of spring 12, the first swing rod 8 by rotary damper 11 and second driving shaft 9 drives second gear 10, and gently backswing is extremely
Initial position, under the action of first gear 6 rotation occurs for second gear 10 in the process.
Under the action of reset spring 22, the mobile transmission item resetted drives third gear 14 to continue instead through the first rack gear 15
To rotation, the second rack gear 17 drives the 4th gear 18 to reversely rotate;Since one-way clutch 19 at this time starts to play driving work
With so the 4th gear 18 reversely rotated drives driven delivery wheel 26 synchronous by one-way clutch 19 with third transmission shaft 20
Rotation;Since cable 39 is wrapped in the top of driven delivery wheel 26, so existing between cable 39 and driven delivery wheel 26 very big
Frictional force;The driven delivery wheel 26 of rotation continues to pull cable 39 from cable disk 38, so that being located on cable 39 actively defeated
Send the part between wheel 7 and driven delivery wheel 26 that relaxation takes place.
When reset spring 22 releases energy and restores to the original state completely, item 16 is transmitted together with the first rack gear 15 and the second rack gear
17 return to initial position together;Driven delivery wheel 26 pulls 39 certain length of cable, so that being located at active delivery wheel 7 on cable 39
Part between driven delivery wheel 26 generates relaxation to greatest extent, avoids the cable disk 38 turned round under external force right
The tensile impact of cable 39 and the damage for making paired cable 39, and then extend the service life of cable 39 and guarantee to make after installation
With safety.
In conclusion beneficial effects of the present invention: motor of the anchoring in electrical drive module 24 in the present invention
After shutting down, cable 39 does not continue to release from cable disk 38, and two contact rollers 32 can be pressed against cable 39;When
Cable disk 38 turned round under external force consciously or unconsciously and to return winding cable 39 when, due to contact roller 32 and actively convey
It takes turns 7 pairs of cables 39 to squeeze, so that cable 39 is not easy to be pulled, and then prevents the revolution of cable disk 38, avoids and be located at
Cable 39 in 39 well of cable is pulled back and causes the influence to ongoing power construction, while also avoiding being returned by moment
The cable 39 tightened is drawn to damage neighbouring personnel;When active delivery wheel 7 is after stopping rotating, reset spring 22 discharges energy
Amount can make driven delivery wheel 26 continue to rotate some angles along its former direction of rotation;Since the larger self weight of cable 39 is so that electricity
Very big frictional force is still remained between cable 39 and driven delivery wheel 26, so continuing that small angle rotation occurs along former direction of rotation
Driven delivery wheel 26 partial cables 39 are pulled out from cable disk 38 so that on cable 39 be located at active delivery wheel 7 with
Relaxed state is partially between driven delivery wheel 26.After stopping bracing wire, the cable disk 38 to have stopped rotating is having
It is turned round under unintentionally external force of anticipating;Between active delivery wheel 7 and driven delivery wheel 26 in relaxed state
Cable 39 is pulled back and be gradually tauted by cable disk 38, and the cable 39 of relaxed state alleviates 39 disk of cable of revolution to cable
39 tensile impact avoids the damage that exceptionally straight cable 39 occurs when being stretched moment, guarantees effective laying of cable 39
And the safe load of cable 39 works after power construction.
