Abstract

The invention discloses a hydraulic cathead structure with the improved safety performance. The hydraulic cathead structure with the improved safety performance comprises a support fixed to a drill floor, a hydraulic cylinder installed on the support, and a steel wire rope winding device connected to the top of the hydraulic cylinder. A shell and a wire outlet are arranged outside the steel wire rope winding device. The left side and the right side of the wire outlet are each provided with an expansion plate connected to the shell. The two expansion plates both extend in the extending-out direction of a steel wire rope. The ends, away from the shell, of the two expansion plates are fixed to a baffle at the same time. A through hole is formed in the baffle and is right opposite to the area between the two expansion plates. By means of the hydraulic cathead structure with the improved safety performance, the problem that in the prior art, safety accidents are caused easily due to rapture of a steel wire rope on a hydraulic cathead is solved, and the purpose of reducing hazards caused after the steel wire rope on the hydraulic cathead ruptures is achieved.

Description

technical field [0001] The invention relates to the field of oil drilling and completion, in particular to a hydraulic cathead structure with improved safety performance. Background technique [0002] With the development of the petroleum equipment industry, the degree of automation of oil drilling rigs is getting higher and higher, and the requirements for drilling rigs are also becoming lighter. In order to meet the requirements of lightweight drilling rigs, it is required that the components of the drilling rig be highly integrated. The hydraulic cat head is used more and more frequently on the drill bit. The hydraulic cat head can greatly improve the efficiency of make-up and breakout, reduce the time for connecting a single root and connecting a column, thereby reducing the time spent on tripping and tripping, and improving the efficiency of drilling completion. Well efficiency. The hydraulic cat head often adopts an integrated structure, which is directly installed on...
