The invention relates to a cable-operated hammering tool () for downhole operations, comprising an extended cylinder () with an axially through-going internal opening in the cylinder (), a hammering part () is arranged in a lower section of the cylinder () and is fitted with a detachable coupling for the connection with downhole equipment, a release strut () is arranged in the upper section of the cylinder () that is connected to a cable which is connected to a surface installation, the hammering part is detachably fastened to the cylinder () with the help of, at least, one locking body (). The release strut () is functionally connected to a force spring () for prestressing of this by moving in a first direction, and also functionally coupled to the, at least, one locking body () to be released from this by moving in an opposite direction.

Mechanical hammering tool for use in oil wells

A manual locking assembly for a quick connect coupling includes a cylindrical male pin, a cylindrical sleeve-shaped female part, a rotatable key bolt, a locking bolt retainer, and a spring. The rotatable key bolt is axially arranged and central within the cylindrical sleeve-shaped female part, and has a quadrilateral locking block, a cylindrical guiding flange, and a cylindrical locking bolt having millings on opposite sides. The locking bolt retainer has a cylindrical body including a transversal hole having a radius that corresponds with an outer radius of the cylindrical locking bolt and a groove extending from the transversal hole that corresponds to the millings on the cylindrical locking bolt, a lower flange on a first side of the cylindrical body, and an upper flange located on a second side of the cylindrical body opposite to the first side, the upper flange having an inclined surface on an upper side of the upper flange. The inclined surface of the upper flange is accessible through a hole in the cylindrical sleeve-shaped female part to unlock the manual locking assembly.
