The invention relates to the technical field of oil and gas drilling engineering, in particular to a turnover crown block device. The device comprises a turnover mechanism, the turnover mechanism comprises a turnover frame arranged corresponding to a fixing frame, hydraulic cylinder bases are arranged on the fixing frame and the turnover frame respectively, the two ends of each hydraulic cylinder are connected with lug plates on the two hydraulic cylinder bases through pin shafts II respectively, a double-lug plate is arranged on the fixing frame, and a single-lug plate is arranged on the turnover frame. The double-lug plate and the single-lug plate are connected through a pin shaft I. The roll-over stand can be connected to the derrick body through a detachable support. The overturning type crown block is adopted, it is guaranteed that a wellhead below the vertical derrick has enough operation space, meanwhile, the height of the whole derrick is reduced, the problem that the derrick cannot be mounted on a license plate due to the fact that the derrick exceeds the height limit is solved, the derrick can run on the road according to the law, and the vehicle-mounted advantage is fully played.
本发明涉及石油天然气钻井工程技术领域,特别涉及一种翻转式天车装置。该装置包括翻转机构,所述翻转机构包括与固定架对应设置的翻转架,固定架和翻转架上分别设置液缸座,液缸两端分别与两个液缸座上的耳板通过销轴Ⅱ连接,固定架上设置双耳板,翻转架上设置单耳板,上述双耳板与单耳板之间通过销轴Ⅰ相连接,翻转架能够通过可拆支架连接在井架体上。本发明实现了采用翻转式天车,保证直立井架下方的井口具有足够作业空间,同时降低整车高度,解决其因超过限高而不能上牌照的问题,可依法上路行驶,充分发挥车载的优势。
