A hydraulic turntable for snubbing workover rig

Abstract

The invention relates to a hydraulic turntable for a snubbing workover rig, which includes a box body, an upper box cover, a lower box cover, an output assembly and an input assembly, and the output assembly includes an output gear shaft, an output flange and a thrust Self-aligning roller bearings, the output gear shaft is set through the upper box cover, box body and lower box cover, the output gear shaft is located in the upper box cover and the lower box cover, both of which are equipped with thrust self-aligning roller bearings, the lower end of the output gear shaft The output flange is connected by splines; the input assembly includes the input gear shaft and the input flange. There are multiple input flange holes on the upper case cover, and the input flange is fixed in the input flange hole. There is an input gear shaft, and the input gear shaft is connected with the output gear shaft through transmission. The hydraulic rotary table of the present invention enables the snubbing workover rig to have both drilling and workover functions, and the snubbing workover rig can be ready for operation after arriving at the well site, without the need for other equipment to be used together, and the operation preparation cycle is shortened by 25% Left and right, with high safety performance and long service life.

Description

technical field [0001] The invention relates to the technical field of petroleum drilling and production equipment, in particular to a hydraulic rotary table used for a snubbing workover machine. Background technique [0002] At present, all the snubbing devices produced in China are separated from the workover rig. When going to the site for workover operations, it is necessary to use other mobile equipment to transport the snubbing device to the well site, and then go to a crane to cooperate with it. The operator connects the snubbing operation device with the workover rig, and then connects all the hydraulic pipelines to carry out the workover operation, but it is very inconvenient to operate, because it is operated by two people, and the cooperation is very difficult. Difficult, and the efficiency is very low; In addition, because the workover operation room is installed at the rear of the vehicle, this position not only has a very bad line of sight, but is also very uns...
