Abstract

The invention discloses a pipe connector, belonging to the field of oil drilling and extracting and aiming to provide a pipe connector with simple structure and convenient operation as well as capability of quickly lifting and lowering a drill rod to complete screwing on and fastening the drill rod without using other machines and tools and simultaneously completing casing running operation. The pipe connector comprises a main shaft (1), and is characterized in that the main shaft (1) is connected with a bearing barrel body (12); a rotary oil sleeve (2) is sleeved on the bearing barrel body (12); the lower end of the bearing barrel body (12) is connected with a first slip bowl body (10) and a second slip bowl body (5); and the first slip bowl body (10) and the second slip bowl body (5) can be folded and cooperatively used, the first slip bowl body (10) and the second slip bowl body (5) are respectively provided with a clamping device (3) and a locking device (4). The invention is applicable to being popularized in the oil drilling and extracting field.

Description

technical field [0001] The invention relates to an oil drilling device, in particular to a pipe connecting device. Background technique [0002] In the field of oil extraction, in order to improve drilling rig efficiency and reduce drilling costs, modern drilling rig traveling crane systems are usually equipped with top drives or power faucets. Top drives are suitable for large drilling rigs and deep drilling, and power faucets are suitable for light drilling rigs. . No matter what type of drilling rig it is, during the drilling process, it is necessary to lift and lower the drill pipe, install and unload the casing, and this process requires a lot of machines to cooperate with each other to complete, such as iron Drillers, hydraulic tongs, casing tongs, etc. Generally speaking, when lifting and lowering drill pipes, a drilling rig equipped with a top drive requires the cooperation of iron drillers or hydraulic-pneumatic tongs, and the cooperation of casing tongs is even m...
