A land-use inflatable and sealed oil delivery arm

Abstract

The invention relates to a novel land inflation sealing type oil transfer arm which comprises an inner arm, an outer arm and a plurality of rotating connectors. The inner arm is connected with a column, the inner arm is connected with the outer arm through the rotating connectors, and an upper flange and a lower flange are locked at the upper ends and the lower ends of the rotating connectors respectively. A vertical position detector is arranged above the connection end of the inner arm and the column at the bottom, a static grounding controller is arranged at the center of a column base, a position sensor is arranged under the connection end of the outer arm and the rotating connectors, a flange fixing end is installed on the end portion of a vertical pipe on the outside of the outer arm, and a capsule is installed on each side of the outer surface of the flange fixing end. The novel land inflation sealing type oil transfer arm has the advantages that the rotating connectors stable in sealing structure are arranged, parts of the rotating connectors are evenly shrunk under the low temperature working condition, the problem that the sealing face is uneven in deformation under low temperature is effectively solved, and the problem that the arm is cracked up accidentally is solved by means of a position detection function.

Description

technical field [0001] The invention relates to a loading and unloading device, in particular to an inflatable and sealed oil delivery arm for land use. Background technique [0002] According to the way of liquid transportation, the liquid oil delivery arm can be used for land transportation and water transportation. Land transportation can be divided into train transportation and automobile transportation, which are usually called cryogenic cranes, and water transportation can be divided into ocean transportation and river transportation, which are usually called marine loading and unloading arms. The low-temperature crane tube is specially used for the loading and unloading of low-temperature medium tank trucks. The various parts of the rotary joint shrink under low-temperature working conditions, the sealing surface is deformed unevenly, and the sealing structure cannot be guaranteed, so the low-temperature sealing requirements cannot be achieved; During the loading and...

AI Technical Summary

Problems solved by technology

The low-temperature crane tube is specially used for the loading and unloading of low-temperature medium tank trucks. The various parts of the rotary joint shrink under low-temperature working conditions, the sealing surface is deformed unevenly, and the sealing structure cannot be guaranteed, so the low-temperature sealing requirements cannot be achieved; During the loading and unloading process, the moisture in the air will freeze in the raceway and damage the raceway, resulting in inflexible rotation of the rotary joint; at the same time, it needs to be pointed out that when the crane pipe docking frame is installed in the loading skid, the explosion-proof Proximity switch, after the loading is completed, the loading crane tube must be put back on the docking frame to prevent the loading crane tube from swinging accidentally, damaging nearby equipment or accidentally crashing the crane tube. There is a lack of corresponding position detection functions between the outer arms and between the inner arm and the column; in addition, when the loading and unloading arm loads and unloads liquid chemicals into the tanker, the vertical pipe section outside the outer arm is prone to produce toxic chemicals
