Embodiment

[0027] Such as figure 1 and figure 2 As shown, it is an embodiment of the automatic drill pipe clearing device of the present invention. The device first includes an integral support 1, and the integral support 1 is installed on a slide cylinder 7. Under the action of the slide cylinder 7, the integral support 1 It can reciprocate linearly from side to side, and switch between the clearing position and the lubricating position, so as to realize the clearing and lubrication of the drill pipe.

[0028] Two hanging lugs 2 are suspended symmetrically on the overall support 1, and a push rod 3 connecting the two is arranged between the two lifting lugs 2, and the two lifting lugs 2 swing synchronously, so The lower end of the lifting lug 2 is freely suspended with a clearing station 4 and a lubricating station 8. A push rod cylinder 6 is also provided on the integral support 1 , and the piston end of the push rod cylinder 6 is hingedly connected to the push rod 3 to realize the ...

Abstract

The invention provides a drill pipe automatic thread cleaning device. The problems that in the prior art, the work intensity is high and the dangerousness is high when a worker cleans a screw thread of a drill pipe are solved. The drill pipe automatic thread cleaning device comprises an integral support, two lifting lugs are symmetrically hung on the integral support, a push rod connecting the twolifting lugs is arranged between the two lifting lugs, and the two lifting lugs swing synchronously. A thread cleaning work station is freely hung at the lower ends of the lifting lugs, and the thread cleaning work station comprises a thread cleaning pipe which is in a vertical state all the time. A push rod air cylinder is further arranged on the integral support, the piston end of the push rodair cylinder is hinged to the push rod, and thus swinging of the lifting lugs is achieved. The drill pipe automatic thread cleaning device is simple in structure, convenient to use, can relieve the labor intensity and the dangerousness of the worker, and has good practicality.

Description

technical field [0001] The invention relates to the technical field of oil field workover equipment, in particular to a device that is simple in structure, easy to use and capable of automatically cleaning drill pipes. Background technique [0002] Well workover operation refers to a kind of operation of oil drilling and subsequent oil well maintenance, in order to ensure the smooth use of oil wells, maintenance and maintenance measures are taken. Workover operations are characterized by high engineering difficulty and high technical requirements. Large workover equipment must be equipped with special equipment and tools such as overhaul drill pipes and overhaul turntables to carry out work. In the workover operation in the prior art, the most common work content includes tripping out and tripping in. Drilling, as the name suggests, is to lift the downhole drilling tool (such as tubing) out of the wellbore; Drilling, as the name suggests, is to lower the drilling tool into ...
