Automatic pull-up device for oil well pipeline

Abstract

The invention provides an automatic pull-up device for an oil well pipeline. The automatic pull-up device comprises a lifting device, a first clamping mechanism and a second clamping mechanism, and the lifting device is fixedly installed on a base; the first clamping mechanism is fixedly installed at the lower end of the lifting device, and the second clamping mechanism is fixedly installed on thebase, located at the lower end of the first clamping mechanism, and aligned to the axis of the first clamping mechanism; and an oil pipeline is pulled out through the lifting device, the first clamping mechanism and the second clamping mechanism automatically. According to the automatic pull-up device, rotation and upward lifting action can be achieved through the lifting device, and pull-out ofthe oil well pipeline from the ground is benefited; and the clamping mechanisms of the automatic pull-up device are provided with pulleys so that friction with the surface of the oil well pipeline isreduced, and friction with the oil well pipeline can be increased through arrangement of a rubber plate.

Description

technical field [0001] The invention relates to the technical field of oil exploitation industrial equipment, in particular to an automatic pulling device for oil well pipelines. Background technique [0002] The oil well pipe is a pipe installed underground. It is used to guide the oil when oil is extracted. The oil pipe is driven into the ground through the pile driver equipment. When the oil in a place is exhausted, the corresponding pipe needs to be pulled out. , and then replace the mining position, the oil well pipe is relatively long, and the friction with the ground is relatively large, and it is very laborious to pull it out. At present, there is a pipe puller, such as the patent No. CN201610166051.0 provides a "a drill pipe puller The device is composed of beam frame, clamping tiles, etc. The advantage is that it is small in size and can be installed on site. The disadvantage is that the pipe is directly pulled up abruptly, with high resistance, low efficiency, and...
