Problems solved by technology

During the use of existing drill pipe elevators, the opening and closing of the left and right pages of the main body are mainly realized manually. This kind of drill pipe elevator has high operating strength and low safety for operators, which is not conducive to frequent use.
And the existing drill pipe elevator is easy to jam the drill pipe in the process of clamping the drill pipe due to the large rear end gap of the left and right pages of the main body, which affects the normal operation of the work and reduces the work efficiency.

Abstract

The invention discloses a top drive lining type hydraulic drill rod elevator which comprises a main body left hinge and a main body right hinge, wherein rear ends of the main body left hinge and the main body rear hinge are fixedly arranged together through a valve; and a plunger latch is arranged at the front end of the main body left hinge. The top drive lining type hydraulic drill rod elevator is characterized in that a hydraulic cylinder I is arranged at the front end of the main body left hinge; a cylinder body I of the hydraulic cylinder I is fixedly connected with the main body left hinge through a connecting piece I; and a piston rod I of the hydraulic rod I is fixedly connected with the plunger latch. The top drive lining type hydraulic drill rod elevator disclosed by the invention has the advantages that the opening, the closing and the locking of the main body left hinge and the main body right hinge of the hydraulic drive main body are realized; a drill rod is prevented from being clamped in the main body left hinge and the main body right hinge during work; the work efficiency and the safety are improved; and the labor intensity is reduced.

Description

technical field [0001] The invention relates to a drill pipe hoisting device for oil and natural gas exploration, in particular to a top drive liner hydraulic drill pipe elevator. Background technique [0002] The drill pipe elevator is a wellhead tool used for oil and natural gas top drive drilling, and is used to hang the drill pipe during the tripping operation. During the use of existing drill pipe elevators, the opening and closing of the left and right pages of the main body are mainly realized manually. This kind of drill pipe elevator has high operating strength and low safety for operators, which is not conducive to frequent use. And the existing drill pipe elevator is easy to block the drill pipe in the process of clamping the drill pipe due to the large rear end gap of the left and right pages of the main body, which affects the normal operation of the work and reduces the work efficiency. Therefore, a new technical solution is needed to solve the above technical...
