Oil transfer arm rotary joint sealing ring translation replacing device and application thereof

Abstract

The invention provides an oil transfer arm rotary joint sealing ring translation replacing device and application thereof. The device comprises a translation beam, a translation frame and a connection block, wherein the translation frame is horizontally and slidably installed on the translation beam, and the connection block is installed at the lower end of the translation frame through a connector; one end of the translation beam is provided with an installation plate for being connected with an equipment fixing end, and the other end of the translation beam is provided with a limiting plate for preventing the translation frame from falling off; the connector comprises an adjustment nut, the upper end of the adjustment nut is provided with an upper threaded rod for being connected with the translation frame, and the lower end of the adjustment nut is provided with a lower threaded rod for being connected with the connection block; and the upper threaded rod and the lower threaded rod are opposite in direction of spiral. The oil transfer arm rotary joint sealing ring translation replacing device is simple in structure and convenient to use, the translation beam shares the weight of a rotating segment of a rotary joint, a positioning role is played through a long pole, and stability of the relative position relation between the rotating segment and a fixed segment of the rotary joint is always maintained; besides, the translation frame linearly moves on the translation beam, and resetting precision is effectively guaranteed; and when a sealing ring is replaced, operation difficulty is low, and time and labor are saved.

Description

technical field [0001] The invention belongs to the technical field of fluid conveying equipment, and in particular relates to a translational replacement device for a rotary joint sealing ring of an oil conveying arm and its application. Background technique [0002] Rotary joints are widely used in the rotating parts between rigid pipelines of fluid conveying equipment. Due to the erosion of the conveying medium in the pipeline and the influence of the life of the sealing ring itself, the aging of the sealing ring causes the leakage and escape of the medium in the rotating part of the equipment, which poses a great threat to safe production. Regularly check and replace the sealing ring of the rotary joint appears to be particularly important. In the past, when replacing the sealing ring of the rotary joint of the oil delivery arm, the rotating section needs to be hoisted and disassembled by lifting equipment before replacement. After replacing the sealing ring, the rotati...

AI Technical Summary

Problems solved by technology

In the past, when replacing the sealing ring of the rotary joint of the oil delivery arm, the rotating section needs to be hoisted and disassembled by lifting equipment before replacement. After replacing the sealing ring, the rotating section needs to be lifted by lifting equipment. Due to the friction between the steel ball and the raceway The friction between the dust-proof ring and the bearing sleeve is very large. It is extremely difficult to rotate the bearing sleeve during installation, and the screw holes are not easy to align. For equipment that regularly replaces the sealing ring, it is very time-consuming and laborious to repeatedly disassemble and assemble.
