Problems solved by technology

According to the needs of the operation, the top drive slewing mechanism needs to adjust the angle to complete the transfer of the drill pipe with the mouse hole, the drill pipe catwalk, the pipe rower or the second floor derrick. The traditional way is that the driller observes the camera or other operators. Gestures are used to position the top drive rotary head, which is inefficient and prone to safety accidents

Abstract

The invention discloses a top driving system as well as a measuring device and a measuring method of the rotating angle of the top driving system. The top driving system comprises a top driving systembody and a rotating head, wherein the rotating head can rotate relative to the top driving system body. The measuring device of the rotating angle of the top driving system comprises a distance measuring sensor and a to-be-measured part, wherein the distance measuring sensor is arranged on one of the top driving system body and the rotating head, the to-be-measured part is arranged on the other one of the top driving system body and the rotating head, a detection head of the distance measuring sensor corresponds to the to-be-measured part, and when one of the distance measuring sensor and theto-be-measured part rotates along with the rotating head, the distance between the distance measuring sensor and the to-be-measured part is continuously changed. According to the measuring device ofthe rotating angle of the top driving system, the rotating angle of the rotating head can be accurately measured, so that the operation efficiency is improved, and the use cost is reduced.

Description

technical field [0001] The invention relates to the technical field of top drives, in particular to a top drive, a top drive rotation angle measuring device and a measuring method. Background technique [0002] In the modern drilling process, it is necessary to use the top drive slewing mechanism and the lifting ring mounted on the top drive slewing mechanism to complete the operation of the drill pipe or drill string. According to the needs of the operation, the top drive slewing mechanism needs to adjust the angle to complete the transfer of the drill pipe with the mouse hole, the drill pipe catwalk, the pipe rower or the second floor derrick. The traditional way is that the driller observes the camera or other operators. Gestures are used to position the top drive rotary head, which is inefficient and prone to safety accidents. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a top dri...
