Abstract

The invention relates to the technical field of petroleum drilling and production equipment, and discloses a lifting beam system for lifting a derrick of a drilling rig. The hydraulic cylinder is fixed on one side of the connecting lug mechanism, and the top of the piston rod of the pin-piercing hydraulic cylinder is connected with the top of the pin through the pin-threading mechanism, and the bottom of the pin is inserted into the pin hole of the connecting lug mechanism. The pin hole slides freely, and the connecting lug mechanism is installed at the end of the main beam mechanism. The invention adopts the form of beams at both ends, and the connection mode with the derrick of the drilling rig is a plug-in connection, and is fixed with bolts, detachable, and can be transported separately from the derrick of the drilling rig; The pinning method is automatic pinning and unpinning of the pinning cylinder, the connection structure is simple, the connection method is convenient, and the derrick structure is light, which reduces the manufacturing cost of the derrick.

Description

technical field [0001] The invention relates to the technical field of oil drilling and production equipment, in particular to a detachable lifting beam system for lifting the derrick of a drilling rig, which is conveniently connected with a derrick and a hydraulic cylinder. Background technique [0002] Hydraulic cylinder lifting drilling rig is a commonly used method for drilling rig lifting. In the prior art, when the hydraulic cylinder lifts the derrick, in order to realize the connection between the hydraulic cylinder and the derrick, two solutions are usually adopted: 1. A connecting block is arranged on the derrick, which is heavy and cannot be disassembled, and is extremely inconvenient during transportation ; and the liquid cylinder rotation plane is not the same plane as the derrick hoisting rotation plane, it is necessary to specially design a set of complex structure control system to control the rotation of the hydraulic cylinder or adjust it manually to realize...
