DESIGN OF MECHANICAL ACTION DEVICE FOR RETAINING REPLACEABLE TOOL IN SYSTEM FOR CONNECTING UNDERWATER PRODUCTION EQUIPMENT DURING OPERATION Russian patent published in 2020 - IPC E21B43/01 F16L1/26 

FIELD: physics.

SUBSTANCE: invention relates to a design providing retention of a replaceable tool in a system for connecting equipment of underwater production during operation. Design is made with possibility to hold the tool placed in the body with the upper plaque, in the equipment connection system restricted by the interface frame to slots. Design contains two handles with sliders with possibility of extension upwards. Slides can move inside guide bushings fixed on top plate. Contact surfaces of bushings are made with inserts from polymer material. Slides are configured to limit movement by means of cups and a compression spring located between the barrel and the bar. Inside the housing there are connecting mechanisms, each of which consists of twin connecting rods. Inside the housing there are fixators, each of which is fixed on the axis. On lower end of each slider by means of axle and limiting bushings rods are fixed on one side, and on their other side they are fixed to retainer by means of axis. Retainer by means of an axis and limiting bushings is fixed inside the housing. By means of paired connecting rods retainer is able to turn on axis and entrance to slots of coupling frame.

EFFECT: technical result is simplification of design and increased reliability of replaceable tool.
