Light well drill derrick casing pipe straightening hydraulic lifting device

Abstract

The invention provides a light well drill derrick casing pipe straightening hydraulic lifting device which comprises a lifting platform, a rotating guide rail, a wellhead and a derrick. The derrick is arranged outside the wellhead. The outer side wall of the derrick is connected with an erection support. A mounting bracket and the erection support are connected through a rotating pin shaft and fixed through locating pins. The mounting bracket is connected with the rotating guide rail. The rotating guide rail is connected with the lifting platform through an idler wheel assembly. A telescopic hydraulic cylinder is arranged in the rotating guide rail. One end of the telescopic hydraulic cylinder is connected with the lifting platform, and the other end of the telescopic hydraulic cylinder is connected with the bottom of the rotating guide rail. The telescopic hydraulic cylinder is connected with a hydraulic system. A safe limiting device connected with the rotating guide rail is arranged below the lifting platform. An operation handle is arranged in the lifting platform. By the adoption of the technical scheme, the casing pipe straightening hydraulic lifting device is arranged on the outer side of the derrick, and is suitable for being used for installing a telescopic K-type derrick in a sleeved mode and more convenient to operate; the light well drill derrick casing pipe straightening hydraulic lifting device has the advantages of being simple in structure, convenient to maintain, low in machining cost, high in production efficiency and the like.
