Problems solved by technology
This kind of structure requires an additional foundation seat under the base of the drill floor. Hydraulic outriggers are required to pull the upper body of the drill floor and support the entire platform. The disassembly and installation are complicated and inefficient, and are limited by the superhigh transportation. The working height of the drill floor can only be more than five meters, and the application has certain limitations

The invention relates to a semi-trailing derrick floor used in petroleum drilling and repairing equipment, which comprises a derrick floor body, a derrick floor base, a rotatable lifting parallelogram derrick floor consisted of a plurality of posts with two ends hinged between the derrick floor body and the derrick floor base and a hitch frame fixed on the front end of the derrick floor base; thederrick floor body is a frame structure divided into a rotating disk area and a vertical root area; the invention also comprises a rear vehicle frame, the rear vehicle frame consists of two crossbeams and a strut between the two crossbeams; the two crossbeams are respectively connected to the rear end of the derrick floor base in a detachable manner by a connection mechanism; the rigid one-line tow shaft suspension is adopted between the rear vehicle frame and the wheel; a pair of synchronous hydraulic supporting legs capable of extending downwards are mounted at the front end of the derrick floor base; supporting legs for supporting the fallen derrick floor body are disposed on the derrick floor base; and steam heating devices are disposed in the rotating disk area and the vertical root area. The invention can be demounted easily, can not be limited by the superhigh transportation and can satisfy rapid transferring demand and can adapt the operation in low temperature.
Description
technical field [0001] The invention relates to a semi-trailer drill floor for oil drilling and repairing equipment, which can meet the requirements of drilling rig or workover rig operation and fast moving. Background technique [0002] Truck-mounted drilling rigs and workover rigs are used to install turntables, place drill pipes, drill collars, wellhead tools, etc., and provide installation space for wellhead devices and an operating platform for drilling operations. With the requirement of rapid relocation of drilling rigs, the semi-trailer drill floor for oil drilling and repair equipment came into being. It combines the drill floor module with a semi-trailer. Traction and transportation, after arriving at the well site, disengage the tractor, and the semi-trailer rig can be assembled with other modules to carry out drilling operations. [0003] There is a known semi-trailer drill floor used for oil drilling and repair equipment, patent number: ZL200420049300.0, the up...
