The invention discloses a hydraulic lifting device for automatically lifting and placing a derrick, which comprises a base, a derrick main body is arranged at the top of the base, a connecting frame is arranged in the derrick main body, a lifting support is connected to one group of opposite outer walls of the derrick main body and corresponds to the connecting frame, and the lifting support is connected with a piston rod end of a lifting hydraulic cylinder. And the cylinder body end of the lifting hydraulic cylinder is connected with the base. The lifting device solves the problems that the derrick lifting efficiency is low and the safety is low due to the fact that an existing derrick cannot achieve remote control lifting of the derrick.
本发明公开了一种自动起放井架的液压起升装置,包括底座,底座的顶部设置有井架主体,井架主体内设置有连接架,井架主体其中一组相对的外壁且与连接架对应的位置上连接有起升支架,起升支架与起升液缸的活塞杆端连接,起升液缸的缸体端与底座连接。本发明起升装置解决现有井架无法实现远程遥控起放井架而导致起放井架效率低、安全性低的问题。
