Abstract

The invention discloses a rotating joint, a loading arm with the rotating joint and loading equipment with the loading arm. A plurality of radial bearings (5) and/or thrust bearings (4) are installed between a rotating core (3) of the rotating joint (12) and a shell (2). The rotating joint (12) is arranged at the lower end of an inner revolving arm (13) of the loading arm. One end of an outer revolving pipeline (16) is connected with the inner revolving arm (13) through a rotating unit (15). A bearing (24) of the loading equipment is connected with a three-way joint (20) through a shaft (29). A rapid joint (25) is connected with a movable pipeline (17). The loading equipment can be rotated at will in the vertical direction and the horizontal direction through the rotating joint (12) and the rotating unit (15) formed by the rotating joint (12), the rapid joint (25) can be flexibly adjusted to the needed loading position, and the loading equipment is high in pressure resistance, safe, reliable and long in service life.

Description

technical field [0001] The invention relates to the field of loading and unloading equipment, in particular to a rotary joint, a loading and unloading arm including the rotary joint, and loading and unloading equipment including the loading and unloading arm. Background technique [0002] With the rapid development of my country's economy, natural gas has been recognized by more and more people as a new type of clean energy. There are more and more cities using natural gas as the main energy source, and more and more cars using natural gas as energy. , the amount of compressed natural gas and the number of filling stations are increasing, and the loading and unloading devices for compressed natural gas are also increasing. Since the pressure of compressed natural gas is as high as 25MPa, there is a risk of rupture and explosion of storage containers and pipelines. At the same time, it is also a flammable and explosive product, which has the risk of combustion and explosion. ...
