The invention discloses a self-balancing deck crane and a limiting device, and particularly relates to the field of cranes. Comprising a first hydraulic oil cavity and a second hydraulic oil cavity, the first hydraulic oil cavity is connected with a crane body, the first hydraulic oil cavity is slidably and hermetically connected with a first hydraulic rod and a second hydraulic rod, and the second hydraulic oil cavity is slidably and hermetically connected with a third hydraulic rod and a fourth hydraulic rod; pawls are rotationally connected to the fourth hydraulic rod and the second hydraulic rod, the two pawls can only rotate independently and rotate reversely, a ratchet wheel matched with the pawls is connected between the two pawls, a rotating shaft rotationally connected to the first hydraulic oil cavity is arranged in the center of the ratchet wheel in a penetrating mode, and a rotating disc located outside the ratchet wheel is further arranged on the rotating shaft. And the turntable is connected with a cable of the crane main body. According to the technical scheme, the problem that an existing deck crane is prone to overturning in the using process is solved, and self-balancing of the deck crane is achieved.
本发明专利公开了一种自平衡的桥面吊机及限位装置,具体涉及吊机领域。包括第一液压油腔和第二液压油腔,第一液压油腔与吊机主体连接,第一液压油腔滑动密封连接有第一液压杆和第二液压杆,第二液压油腔内滑动密封连接有第三液压杆,第二液压油腔滑动密封连接有第四液压杆,第四液压杆和第二液压杆上均转动连接有棘爪,两个所述棘爪仅能转单转动且转动反向相反,两块棘爪之间连接有与棘爪相配合的棘轮,棘轮中心穿设有转动连接在第一液压油腔上的转轴,转轴上还设有位于棘轮外的转盘,转盘与吊机主体的缆索连接。本发明技术方案解决了现有的桥面吊机在使用过程中易出现倾覆的问题,实现了桥面吊机的自平衡。
