Well drilling power cat machine of saying

The utility model relates to a pipe pole migration device among the drilling process specifically is a well drilling power cat machine of saying. The well drilling power cat way of this design, the mechanism is simple, and degree of automation is high, realizes the upper and lower rig floor of pipe pole through the hydraulic conveying device, has solved on -the -spotly to get rid of tub pole or send the safety problem of tub pole to the rig floor, has reduced intensity of labour, does not need operating personnel to carry out the transport of tub pole. Beneficial effect: well drilling power cat is said through control driving system, realizes sleeve pipe, drilling rod migration, has improved the efficiency of migration, changes the size of hydraulic cylinder drive power, height that adjustable pipe joint pole lifted. Full -automatic remote control has improved migration efficiency, and the design practicality is very strong, safety, high efficiency, under the synergistic reform condition of oil field depletion of numbers at present, has better application prospect.
