Operation principle explanation of the present invention:
Tension force control and counting device make cable have the tension force of a setting in the process of cable reel folding and unfolding cable all the time, guaranteeing the normal operation of cable reel, and provide the signal of the length outside that is used to calculate cable as required in real time.
When cable reel folding and unfolding cable, hydraulic cylinder 13 drives rocking arm 18 and does oscillating motion together with driven pulley 19, under the effect of hydraulic cylinder 13, driven pulley 19 imposes suitable normal pressure, cable 20 is clamped between driving wheel 1 and the driven pulley 19, low speed hydraulic motor 7 is given driving wheel 1 by flat key 6, driving shaft 5 with transmission of power, driving wheel 1 passes to cable 20 by its polyurethane rubber outer rim with driving force and motion, and cable 20 drives driven pulley 19 by frictional force equally and does the rotation of engagement direction with driving wheel 1.
In folding and unfolding cable process, owing to driven pulley 19, magnet proximity switch 11 and two permanent magnet 12 one swings of being installed on the rocking arm 18, on the same diameter when magnet proximity switch 11 and permanent magnet 12 are in installation all the time.When driven pulley 19 under the driving of cable 20 during around driven shaft 10 revolution, the permanent magnet 12 that is bonded on the driven pulley 19 also turns round with driven pulley 19, every block of magnet of a specified duration 12 and magnet proximity switch 11 are near once just sending a signal, with signal input control computer, according to the diameter at magnet proximity switch 11 and permanent magnet 12 places, signal what, just can provide the turnover length of cable.Because the resistance of 19 systems of driven pulley is little, and 20 on cable is non-slip substantially, so the counting precision height.
Now its operation process is divided into two processes of take-up and cable laying.
The take-up process is as follows: when cable reel reclaims cable, the CD-ROM drive motor of cable reel is the motor operating mode, driving cable reel trailing cable 20 also twines, at this moment, the low speed hydraulic motor 7 of described tension force control and counting device is the pump operating mode, according to require control tension value, set the hydraulic-driven pressure of a certain suitable low speed hydraulic motor 7; For guaranteeing that driving wheel 1, driven pulley 19 and cable 20 have enough frictional force, set the hydraulic-driven pressure of hydraulic cylinder 13 according to desired normal pressure.
Payout process is as follows: when cable reel is emitted cable, impose tractive force by described tension force control and counting device, cable 20 is pulled out in cable reel, and this moment, the CD-ROM drive motor of cable reel was the pump operating mode, and the low speed hydraulic motor 7 of control of described tension force and counting device is the motor operating mode.According to require control tension value, except the hydraulic-driven pressure of the low speed hydraulic motor 7 of the CD-ROM drive motor of setting cable reel and control of described tension force and counting device, for guaranteeing that driving wheel 1 and 19 pairs of cables 20 of driven pulley have enough normal pressures, set the hydraulic-driven pressure of hydraulic cylinder 13 as requested.
