Union connection disassembling tool for blowout preventing device

Abstract

The invention relates to a union connection disassembling tool for a blowout preventing device. The tool consists of two semicircular clamping rings (1), two arc-shaped pressing plates (2) and steel balls (6), wherein the two semicircular clamping rings (1) are connected into a circular clamping ring through a bolt pair (4); semicircular grooves (7) are formed on the end faces of the two semicircular clamping rings (1) uniformly; circular through holes (5) are correspondingly formed on the two arc-shaped pressing plates (2); and the two arc-shaped pressing plates (2) are fixed on the two semicircular clamping rings (1) respectively to clamp the steel balls (6) between the semicircular grooves (7) and the circular through holes (5) and make the steel balls (6) partly protrude outside the arc-shaped pressing plates (2) and freely roll. By the tool, when a union nut is screwed off at one end of equipment to be disassembled by using an axial force effect generated by rotating the union nut, the two kinds of equipment connected by a thread pair can be separated; and the disassembly time is short, the operation cost is low, and the labor intensity is low. The structure of the tool is simple, the volume of the tool is small, the weight of the tool is light and the installation and use of the tool are convenient.

Description

technical field [0001] The invention belongs to the technical field of oil field logging operations, and in particular relates to a union connection and disassembly tool for a blowout preventer. Background technique [0002] The equipment of the blowout preventer used in oil field logging operations is basically connected by union joints. Due to the friction of the sealing pair formed by the O-ring, it is inconvenient to disassemble, especially for equipment with large diameters. Disassembly is more difficult. At present, the union nut is basically unscrewed to fix the equipment at one end, and the equipment at the other end is manually pulled out or knocked out. The disassembly time is long, the labor intensity is high, and the operating cost is high. Contents of the invention [0003] The technical problem solved by the present invention is to design a union disassembly tool for the blowout prevention device. The axial force generated when the union nut is rotated is use...
