Preferably, described controller is micro computer, single-chip microcomputer or PLC.
For ease of the lifting of domination set electric pole, preferably, described controller be at least provided with rising stem button and fall bar button, and controller is arranged in pilothouse.
Preferably, the outboard end circumference of described fixed pin shaft is provided with spline plane, and the outboard end of fixed pin shaft is plugged on interior in-core.
Preferably, described lifting solenoid valve is 3-position-3-way solenoid valve or 3 position-5 way solenoid valve.
Preferably, described stop solenoid valve is two-position three way magnetic valve.
The utility model is by the lateral surface setting angle sensor in the annular end of extension spring screw rod, thus make controller can angle residing for real-time perception extension spring screw rod, and a position of the corresponding trolley pole of each angle residing for extension spring screw rod, therefore, this angle signal can be utilized to carry out domination set electric pole and be arranged on the trolley head of trolley pole end.
Specifically, controller according to the angle of extension spring screw rod for the good control program of parameter designing and the signal of angular transducer that obtains in real time control lifting solenoid valve and stop solenoid valve, then be elevated air chamber by lifting solenoid control to exit, inflate or close, the trolley pole controlled by lifting air chamber is made to realize rising, declining or hovering, by stop solenoid control stop chamber inflated or venting, make the spinner controlled by stop air chamber realize stopping and freely rotating, and then the trolley pole be indirectly connected with spinner can not be swung maybe can swing.
When needs make trolley head make contact, controller is pressed rising stem control program domination set electric pole and is risen, when extension spring screw rod rotates to trolley pole the speed governing angle that rising stem control program sets, controller controls lifting solenoid valve, lifting air chamber is closed, trolley pole hovering some seconds (cushioning before making contact), then, controller then controls to be elevated solenoid valve, lifting air chamber is made to continue venting, thus the trolley head being arranged on trolley pole end can be made contact with suitable speed, avoid and large impact was caused to gauze;
When needs fall trolley pole and trolley head, controller declines by falling bar control program domination set electric pole, after setting the speed governing at speed governing angle place, automatically trolley pole and trolley head are dropped to the position set parked, and by stop air chamber to the braking of spinner, trolley pole can not be swung;
When trolley head off-line, the gauze distress resolves that trolley head normally bears, the extension spring connected with trolley pole is shunk automatically, and extension spring screw rod is forwarded to new angle that one exceeds angular range of normally making contact, now, namely controller judges trolley head off-line automatically by off-line control program, and by falling bar control program domination set electric pole and trolley head, to drop to the position set parked, and by stop air chamber to the braking of spinner, trolley pole can not be swung, avoid trolley pole and trolley head to pull and damage gauze or passing oversize vehicle is threatened.
The trolley pole that the utility model solves existing current-collector lacks cushioning control in lifting process, and rising or falling speed can not regulate automatically, when trolley head is made contact, gauze is produced to the problem of great impact; Simultaneously, solve in driving conditions, after trolley head off-line, driver is difficult to Timeliness coverage, to carry out the problem of falling bar operation, there is adjustable trolley pole rising or falling speed, the off-line of automatic sensing trolley head, and automatically domination set electric pole and trolley head drop to the position set parked, control reliable advantage.
