Loading arm pipeline connecting structure convenient to disassemble and assemble

Abstract

The invention discloses a loading arm pipeline connecting structure convenient to disassemble and assemble. The loading arm pipeline connecting structure comprises a bent pipe, wherein a first connecting flange is welded to one end of the bent pipe; a vertical pipe is connected to the lower end of the bent pipe; a second connecting flange is welded to one end, opposite to the bent pipe, of the vertical pipe; first side blocks are fixedly connected to two sides of the first connecting flange; second side blocks are fixedly connected to two sides of the second connecting flange; and limiting mechanisms are connected between the first side blocks and the second side blocks which are opposite in pairs, and the limiting mechanisms comprise bolts. The loading arm pipeline connecting structure has the beneficial effects that through the arrangement of the limiting mechanisms, the bolts of the limiting mechanisms are twisted between the first side blocks and the second side blocks, by holding limiting rings of adjusting nuts, due to the fact that the middles of the limiting rings are of a hollow structure, fingers can conveniently stretch into the limiting rings to hold the limiting rings, the adjusting nuts are twisted to be in threaded connection with the corresponding bolts, so that installation can be completed by fixing the first connecting flange and the second connecting flange, a special tool is not needed, and the loading arm pipeline connecting structure is very convenient.

Description

Technical field: [0001] The invention belongs to the technical field of crane tube pipe connection accessories, in particular to a crane pipe pipe connection structure that is easy to assemble and disassemble. Background technique: [0002] The crane pipe is a mechanical equipment used for liquid loading and unloading in petroleum and chemical wharfs. It can be used to transport the medium in the pipe such as oil, water, etc., also known as the fluid loading and unloading arm. The transmission efficiency is also very high security. [0003] Under the existing technology, when connecting the crane tube pipeline, it is inconvenient to disassemble and clean the pipeline welded by the connecting flange, and it is also inconvenient to carry out maintenance when the crane tube pipeline is damaged; when the bolt is connected, the bolt and the flange The connection is also prone to moisture and rust, and the connection is easily damaged and unstable; the sealing ring at the flange ...
