Abstract

The invention relates to the technical field of height-adjustable corner foundations in the oil well drilling industry, in particular to a lifting type corner foundation, which comprises a left supporting rod, a right supporting rod, a corner foundation body, an upper pressure plate and a lower pressure plate. Lower portions of the left supporting rod and the right supporting rod are respectively perpendicularly fixedly mounted in the corner foundation body, the upper pressure plate and the lower pressure plate which can be adjusted vertically are fixedly mounted between upper portions of the left supporting rod and the right supporting rod via fasteners, opposite half circles are arranged in middles of the upper pressure plate and the lower pressure plate, and hooks are respectively fixedly mounted on two corresponding sides of the upper portion of the corner foundation body. The lifting type corner foundation is reasonable and compact in structure and convenient in use, the upper pressure plate and the lower pressure plate which can be vertically adjusted are fixedly mounted, the height of a hard tube can be conveniently adjusted without filling, workload is reduced, and installation efficiency of the hard tube is improved.

Description

technical field [0001] The invention relates to the technical field of height-adjusting device tools in the petroleum drilling industry, and relates to a lifting type foundation pier. Background technique [0002] There are many pipelines involved in the oil drilling industry, most of which require the use of hard pipes, such as blowout prevention pipelines, blowout pipelines, oil testing pipelines, and various connecting pipelines for managed pressure drilling, etc. In the process of connecting these pipelines, often It is necessary to adjust the height of each pipeline in order to align with the flange or the end. If ordinary foundation piers are used, the height adjustment can only be done by digging deep or filling the bottom of the foundation pier. Field practice shows that this method will increase a lot of workload , time-consuming and laborious. Contents of the invention [0003] The present invention provides a lift-type foundation pier, which overcomes the above...
