The invention discloses a travelling crane variable-frequency speed regulation control system special for a pipe pile. A cab is provided with a left cart limiting alarm, a right cart limiting alarm and a display screen, a travelling crane I calibrator and a travelling crane II calibrator are additionally installed, and the above devices are connected with a PLC through data lines. An upper-row port of the PLC is sequentially connected with a travelling crane I signal input, a travelling crane II signal input, the left cart limiting alarm, the right cart limiting alarm, travelling crane I and II frequency converter input signal acquisition and travelling crane I and II limit position alarm. A lower-row port of the PLC is sequentially connected with a travelling crane I lifting hook superelevation alarm, a travelling crane II lifting hook superelevation alarm, a travelling crane I overspeed alarm and power failure, a travelling crane II overspeed alarm and power failure, a travelling crane I double-encoder contrast imbalance alarm, a travelling crane II double-encoder contrast imbalance alarm, a left cart limit alarm and deceleration, a right cart limit alarm and deceleration and a relay. The traveling crane improved through the system meets the requirements of high-strength and high-load work without barriers in the running process, and the running safety of the traveling crane is improved.
