A fluid loading and unloading arm stopper

Abstract

Disclosed is a fluid loading and unloading arm parking device. The fluid loading and unloading arm parking device comprises a parking box containing the tail end of a fluid loading and unloading arm; the parking box is provided with a sealing device matched with a port of the tail end of the loading and unloading arm and a locking device matched with an arm body of the tail end of the loading and unloading arm; the locking device comprises a feeding tank matched with the arm body of the tail end of the loading and unloading arm, a limiting rod and a driving rod; a linkage rod is arranged between the inner end of the limiting rod and the inner end of the driving rod in a hinged mode; a locking groove is formed in an internal joint arm of the limiting rod; an elastic locking pin matched with the locking groove is disposed on the part, located on one side of an inlet of the feeding tank, of a locking box; a return unlocking mechanism of the elastic locking pin is disposed on the locking box. According to the functions of the fluid loading and unloading arm parking device, when a low-temperature loading and unloading arm does not work, the tail end of the fluid loading and unloading arm is parked in a box body, the use cost of sealing members is reduced, the labor intensity of field operation is greatly relieved, and equipment is effectively protected. The purposes of low labor intensity, safety, reliability and material saving are achieved, and the social benefits are good.

Description

technical field [0001] The invention relates to a fluid loading and unloading device, in particular to a fluid loading and unloading arm stopper. Background technique [0002] The loading and unloading arm is the main equipment for fluid loading and unloading in the petrochemical industry. Before the present invention, the loading and unloading arm had no suitable docking device. In order to prevent the cryogenic fluid from swinging during non-working periods, the manufacturer adopted a method of welding a Hang up the hook, seal the end with blind flanges plus winding pads and multiple sets of fasteners (at least 4 sets), and then hang the loading and unloading arm, resulting in high labor intensity and consumption of seals, and labor tools are required on site. After being hung up, the outriggers of the loading and unloading arms are still in a free state, which may cause the outriggers to collide with each other and damage the equipment.

Since the outrigger of the loading and unloading arm is still in a free state after being hung up, it may cause the outriggers to collide with each other and damage the equipment
