Then power on, the output shaft in electrical drive module 24 drives the first coaxial tooth by the first transmission shaft 5 Wheel 6 and 7 synchronous rotary of active delivery wheel, the rotary damper 11 being nested on second driving shaft 9 play damping action, rotation resistance Buddhist nun's device 11 prevents first gear 6 from driving second gear 10 that rotation occurs by second driving shaft 9；Due to pair of rotary damper 11 The rotation of second gear 10 plays damping action, so first gear 6 not will drive second gear 10 and occur around second driving shaft 9 The rotation of central axis；First gear 6 drives the first swing rod 8 by second gear 10, second driving shaft 9 and rotary damper 11 It is swung around the first transmission shaft 5 to third gear 14, the first leaf spring 12 is by compression and energy storage；When second gear 10 is in the first swing rod 8 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.

The present invention is not only suitable for cable, is also suitable for optical cable, optoelectronic composite cable, even rope class, spinning class etc..
