Benefits of technology

The patent describes a tool for holding a well column pipe in place during drilling. The tool has a pivot arm with teeth that bind to the pipe, preventing it from sliding downwards. The tool can be raised and placed over the pipe, and then closed to securely hold the pipe in place. The tool can also be reapplied at different locations on the pipe to further support it. The technical benefit is a safer and more stable method of drilling wells.

Problems solved by technology

Known configurations of such pipe holding tools are often excessively mechanically complex, and are difficult, cumbersome, and awkward to utilize.

Embodiment Construction

[0024]Referring now to the drawings and in particular to Drawing FIGS. 1-3, a suitable embodiment of the instant inventive well column pipe holding tool incorporates a well head bridging plate which is referred to generally by Reference Arrow 1. Such plate 1 has a lateral end which is positioned leftwardly according to the view of FIG. 1, an oppositely lateral end opposite the lateral end, a longitudinal end facing away from the viewer of FIG. 1, and an oppositely longitudinal end facing toward the viewer of FIG. 1.

[0025]The plate 1 has a seam 2 which extends oppositely laterally from the plate's lateral end, such seam 2 dividing the plate 1 into longitudinal and oppositely longitudinal segments 3 and 5. In a suitable embodiment, the seam 2 is specially configured to form and function as a tongue and groove combination or joint. The tongue portion 10 of such joint extends longitudinally from the longitudinal end of the oppositely longitudinal plate segment 5, and the groove portion ...

Abstract

A tool for holding a well column pipe, the tool incorpo-rating a plate having a lateral end, an oppositely lateral end, a longitudinal end, and an oppositely longitudinal end; a seam extending oppositely laterally from the plate's lateral end, the seam dividing the plate into longitudinal and oppositely longitudinal segments; a hinge connected operatively to the plate at a lateral end of the seam; a releasable latch connected operatively to the plate at an oppositely lateral end of the seam; a jaw connected operatively to a segment selected from the group consisting of the plate's longitudinal segment and the plate's oppositely longitudinal segment, the jaw being adapted for frictional engagement with the well column pipe; and a jack screw actuator for driving the well column pipe against the jaw.

Description

FIELD OF THE INVENTION[0001]This invention relates to water wells having a casing which defines a vertically extending hollow bore, such bore housing a vertically extending water conveying column pipe. More particularly, this invention relates to tools which are adapted for temporarily holding such well column pipes at a partially raised position in relation to the casing's upper opening.BACKGROUND OF THE INVENTION[0002]Maintenance of a water well often entails periodically vertically extracting the well's column pipe from the well's bore for performance of maintenance upon the column pipe or upon a pump mounted to the pipe's lower end. To perform such maintenance, a pipe lifting apparatus is often applied to the well's column pipe for raising the column pipe out of the well's bore, such apparatus often having a lifting stroke which spans only a small fraction of the length of the column pipe. Accordingly, such lifting apparatus must be operated progres-sively or in successive steps...
