The invention discloses a quay crane balance energy-saving system and a counterweight trolley protection device, a counterweight trolley can move along a track arranged in a quay crane door leg, and the counterweight trolley has a lower limit working position; the counterweight trolley protection device comprises an anchoring device which can be drawn out or inserted into the shore bridge door leg, when the counterweight trolley needs to be overhauled or does not work, the counterweight trolley is lowered to the lower limit working position, the anchoring device is inserted into the shore bridge door leg, and the counterweight trolley is stably supported and fixed to the lower limit working position. Through the arrangement, the counterweight trolley can be conveniently fixed and maintained at the lower limit working position, the reliability and safety of the maintenance work are improved, meanwhile, the loss of the lifting rope can be reduced, and the safety of the quay crane is further improved. In addition, when the counterweight trolley works normally, the anchoring device can be pulled out of the shore bridge door leg, and the risk caused by interference between the counterweight trolley and the anchoring device in the running process is effectively avoided.

    本发明公开了一种岸桥平衡节能系统及配重小车保护装置,所述配重小车可沿岸桥门腿内设置的轨道移动,所述配重小车具有下极限工作位置;所述配重小车保护装置包括可抽出或插入到岸桥门腿内锚定装置,在配重小车需要检修或者不工作时,将配重小车下放至下极限工作位置,锚定装置插入到岸桥门腿内,使配重小车被稳定支撑固定在下极限工作位置。如此设置,不仅方便配重小车在下极限工作位置的固定及检修工作,提高检修工作的可靠性和安全性,同时还能减少吊绳的损耗,进一步提升岸桥的安全性。并且,在配重小车正常工作时所述锚定装置可抽出于岸桥门腿,有效地避免配重小车运行时与锚定装置干涉带来的风险。
