[0013] The method for unloading the reel of the above cable reel quick-change system with power cut-off includes the following steps:

[0014] S1. Control the solenoid directional valve Ⅴ so that the P port communicates with the A port and the B port communicates with the T port through the support arm lowering button. The hydraulic oil flowing out of the hydraulic pump enters the rod chamber of the lifting cylinder through the P port and A port of the solenoid directional valve Ⅴ, and the A1 port and A2 port of the hydraulic lock. The hydraulic oil in the rodless chamber of the lifting cylinder flows back to the fuel tank through the B2 port and B1 port of the hydraulic lock, and the B port and T port of the solenoid directional valve Ⅴ. The lifting cylinder contracts and the support arm descends until the cable reel contacts the support surface, and the travel switch in the lifting cylinder closes.

[0015] S2. The control host receives the signal that the travel switch is closed, and determines whether the hydraulic oil flow direction of the solenoid directional valve Ⅱ is from the A1 port to the A2 port and whether the hydraulic oil flow direction of the solenoid directional valve Ⅲ is from the B2 port to the B1 port. If so, the control host controls the solenoid directional valve Ⅰ to make the P port communicate with the A port and the B port communicate with the T port. The hydraulic oil flowing out of the hydraulic pump enters the A port of the drive motor through the P port and A port of the solenoid directional valve Ⅰ and the A1 port and A2 port of the solenoid directional valve Ⅱ, flows out from the B port of the drive motor, and returns to the fuel tank through the B2 port and B1 port of the solenoid directional valve Ⅲ and the B port and T port of the solenoid directional valve Ⅰ. The drive motor rotates forward.

[0016] S3. Drive the V-shaped plate to rotate through the drive motor until the opening direction of the V-shaped plate is consistent with the driving direction of the cable reel handling vehicle. The 360° inclination sensor transmits the signal to the control host, and the control host controls the solenoid directional valve Ⅱ and the solenoid directional valve Ⅲ to reverse simultaneously, the drive motor stops rotating, and the control host controls the output end of the linear motor to retract, and the bolt disengages from the locking hole.

[0017] S4. After the bolt is opened, the control host controls the solenoid directional valve Ⅳ to make the P port communicate with the B port and the A port communicate with the T port. The hydraulic oil flowing out of the hydraulic pump enters the rod chamber of the locking cylinder through the P port and B port of the solenoid directional valve Ⅳ. The locking cylinder contracts and the cover plate is opened.

[0018] S5. The cable reel handling vehicle moves forward until the triangular clamping column of the cable reel is completely disengaged from the V-shaped plate, and the contact switch is disconnected, completing the unloading of the reel.

[0019] The method for unloading the cable reel of the above cable reel quick-change system with power cut-off includes the following steps:

[0020] S1. Control the solenoid directional valve Ⅴ so that the P port communicates with the A port and the B port communicates with the T port through the support arm lowering button. The hydraulic oil flowing out of the hydraulic pump enters the rod chamber of the lifting cylinder through the P port and A port of the solenoid directional valve Ⅴ, and the A1 port and A2 port of the hydraulic lock. The hydraulic oil in the rodless chamber of the lifting cylinder flows back to the fuel tank through the B2 port and B1 port of the hydraulic lock, and the B port and T port of the solenoid directional valve Ⅴ. The lifting cylinder contracts and the support arm descends until the cable reel contacts the support surface, and the travel switch in the lifting cylinder closes.

[0021] S2. When the control host receives the signal that the travel switch is closed, it determines whether the hydraulic oil flow direction of the electromagnetic directional valve II is from port A1 to port A2 and whether the hydraulic oil flow direction of the electromagnetic directional valve III is from port B2 to port B1. If so, the control host controls the electromagnetic directional valve I to make port P communicate with port A and port B communicate with port T. The hydraulic oil flowing out of the hydraulic pump enters port A of the drive motor through port P and port A of the electromagnetic directional valve I, port A1 and port A2 of the electromagnetic directional valve II, and flows out of port B of the drive motor, and then returns to the fuel tank through port B2 and port B1 of the electromagnetic directional valve III, port B and port T of the electromagnetic directional valve I, and the drive motor rotates forward.

[0022] S3. The V-shaped plate is driven by the drive motor to rotate until the opening direction of the V-shaped plate is consistent with the driving direction of the cable reel handling vehicle. The 360° inclination sensor transmits the signal to the control host, and the control host controls the electromagnetic directional valve II and the electromagnetic directional valve III to reverse simultaneously, the drive motor stops rotating, the control host controls the output end of the linear motor to retract, and the bolt disengages from the locking hole.

[0023] S4. After the bolt is opened, the control host controls the electromagnetic directional valve IV to make port P communicate with port B and port A communicate with port T. The hydraulic oil flowing out of the hydraulic pump enters the rodless cavity of the locking cylinder through port P and port B of the electromagnetic directional valve IV, and the locking cylinder contracts to open the cover plate.

[0024] S5. The cable reel handling vehicle reverses until the triangular clamping column of the cable reel is completely embedded in the V-shaped plate and the contact switch is closed.

[0025] S6. After the control host receives the signal that the contact switch is closed, it controls the electromagnetic directional valve IV to make port P communicate with port A and port B communicate with port T. The hydraulic oil flowing out of the hydraulic pump enters the rodless cavity of the locking cylinder through port P and port A of the electromagnetic directional valve IV and the balance valve, and the locking cylinder extends to close the cover plate.

[0026] S7. By pressing the support arm rising button, the control host controls the electromagnetic directional valve V to make port P communicate with port B and port A communicate with port T. The hydraulic oil flowing out of the hydraulic pump enters the rodless cavity of the lifting cylinder through port P and port B of the electromagnetic directional valve V, port B1 and port B2 of the hydraulic lock. The hydraulic oil in the rod chamber of the lifting cylinder flows back to the fuel tank through port A2 and port A1 of the hydraulic lock, port A and port T of the electromagnetic directional valve V. The lifting cylinder extends, and the support arm rises until the cable reel is separated from the support surface, and the travel switch in the lifting cylinder is disconnected.

[0027] S8. When the control host receives the signal that the travel switch is disconnected, it controls the electromagnetic directional valve I to make the P port communicate with the B port, and the A port communicate with the T port. The hydraulic oil flowing out of the hydraulic pump enters the B port of the drive motor through the P port and B port of the electromagnetic directional valve I and the B1 port and B2 port of the electromagnetic directional valve III, flows out from the A port of the drive motor, and returns to the fuel tank through the A2 port and A1 port of the electromagnetic directional valve II and the A port and T port of the electromagnetic directional valve I. The drive motor rotates in the reverse direction until the opening direction of the V-shaped plate is inconsistent with the driving direction of the cable reel truck. The electromagnetic directional valve I returns to the neutral position, and the drive motor stops rotating. The control host controls the output end of the linear motor to extend, and the bolt inserts into the locking hole to close the V-shaped plate and complete the disk loading.

[0029] 1. The connection between the drive motor and the cable reel can be cut off. When the drive motor is damaged, the connection between the two can be cut off, and the cable can be manually wound and unwound by manually turning the cable reel to realize flexible operation.

[0059] Embodiment 2

[0060] The method for unloading the cable reel of the above-mentioned power-cuttable cable reel quick-change system includes the following steps.

[0061] S1, control the energization of K9 of the electromagnetic directional valve V18 through the support arm lowering button. It works in the left position, with the P port communicating with the A port and the B port communicating with the T port. The hydraulic oil flowing out of the hydraulic pump 11 enters the rod chamber of the lifting cylinder 3 through the P port and A port of the electromagnetic directional valve V18, and the A1 port and A2 port of the hydraulic lock 19.

The lifting cylinder 3 contracts, and the support arm 2 descends until the cable reel 1 contacts the support surface (such as the ground), and the travel switch 6 in the lifting cylinder 3 closes.

[0062] S2, the control host receives the signal that the travel switch 6 is closed, and judges whether the hydraulic oil flow direction of the electromagnetic directional valve II14 is from the A1 port to the A2 port and whether the hydraulic oil flow direction of the electromagnetic directional valve III15 is from the B2 port to the B1 port (that is, whether K6 and K7 are energized simultaneously). If so, the control host controls the energization of K1 of the electromagnetic directional valve I13. It works in the left position, with the P port communicating with the A port and the B port communicating with the T port.
