Anti-dropping device for hydraulic decoking system

Abstract

An anti-dropping device for a hydraulic decoking system comprises a lifting mechanism, a lever mechanism, a locking mechanism, a guide mechanism and a support. Locking guide rails for guiding the support to perform vertical motion are arranged on two sides of the support, the support is provided with the guide mechanism matched with the locking mechanism, the lifting mechanism is arranged at the top end of the support and provided with a lifting rod, the lifting rod penetrates a through hole in the support downwards and is connected with the locking mechanism through the lever mechanism fixed on the support, the part of the lifting rod located between the lever mechanism and the support is sleeved with a returning spring, the returning spring can push the lever mechanism to move when the lifting mechanism drops, and the returning spring enables the locking mechanism to be in contact with the locking guide rails. The anti-dropping device is simple in structure, reasonable in design, low in processing and manufacturing cost, long in continuous failure-free running cycle, high in safety reliability and low in device cost, and accidental injury accidents caused to operators due and caused by device dropping are effectively avoided.

Description

technical field [0001] The invention relates to a safety protection device for hydraulic decoking equipment of a delayed coking device in the petroleum refining industry, in particular to a safety device for preventing accidental fall of equipment on a delayed coking and decoking system. Background technique [0002] Delayed coking is a petroleum secondary processing technology. It uses hydrogen-depleted heavy oil as raw material, which is rapidly heated to the coking reaction temperature through a heating furnace, and then enters the coke tower for coking reaction. Heavy oil undergoes deep thermal cracking and condensation reactions at a high temperature of 500°C, and the gas, gasoline, diesel, and wax oil produced are transported to downstream devices for processing through pipelines, and hundreds of tons of coke produced are left in the coke drum. The coke in the coke tower is gradually cooled to below 120°C by steam and water, then the top and bottom cover machine of the...

AI Technical Summary

Problems solved by technology

[0004] Up to now, the delayed coking unit in domestic oil refineries basically has no anti-fall equipment when removing coke during the production process. The decoking equipment weighs about 8 tons. Once a falling accident occurs, the decoking equipment, coke tower, and other equipment will be severely damaged Large damage, or even scrapping, may sometimes endanger personal safety, and there is a great potential safety hazard, which brings great risks to the safe production of the enterprise; the service life of the equipment cannot be fully utilized, which restricts the rapid development of petrochemical enterprises. pace
