The invention discloses a lifting device and a lifting method for vertically lifting a derrick, and belongs to the technical field of petroleum drilling machine devices. The structure comprises a derrick base section, a plurality of derrick sections capable of being arranged on the derrick base section and a crown block arranged at the top of the derrick sections, and a lifting system used for lifting the derrick sections is arranged on the derrick base section; the derrick base section is provided with a plurality of supporting block devices; different from a traditional structural design in structural design, the structure of the derrick supporting block device is optimized, oil cylinder automatic control is adopted, operation safety is improved, and lifting efficiency is improved. Rolling wheels are optimally designed at the ends of the supporting blocks, and when the supporting blocks are vertically lifted, the rolling wheels roll on the guide plates on the side faces of the lifting sections. And the locking effect can be effectively achieved in time in the lifting process of the derrick, which is the technical effect which cannot be achieved by a traditional structure, and therefore the safety coefficient of lifting of the whole derrick is guaranteed.
本发明公开了一种垂直起升井架的起升装置及起升方法,属于石油钻机装置技术领域;该结构包括井架基段,可设置与井架基段上的多段井架段,以及设置于井架段顶部的天车,所述井架基段上设置有用于起升井架段的起升系统;所述井架基段设置有多个支撑块装置;本发明在结构的设计上与传统结构设计不同的是,优化井架支撑块装置的结构,采用油缸自动控制,提高操作安全性,提升起升效率。支撑块端部优化设计滚动轮,垂直起放时,滚动轮在起升段侧面的导向板上滚动。从而实现精准的监控,以及针对井架起升的过程中能够及时有效的实现锁定效果,这也是传统结构并不能到达的技术效果,从而保证了整个井架起升的安全系数。
