An anti-falling device for a hydraulic decoking system

Abstract

An anti-falling device for a hydraulic decoking system, comprising a lifting mechanism, a lever mechanism, a locking mechanism, a guiding mechanism and a bracket, the two sides of the bracket are provided with locking guide rails for guiding the vertical movement of the bracket, and the bracket is provided with The guide mechanism matched with the locking guide rail, the lifting mechanism is arranged on the top of the bracket, the lifting mechanism is provided with a lifting rod, and the lifting rod passes through the through hole set on the bracket downwards, and passes through the lever mechanism fixed on the bracket and the lock. The tension mechanism is connected, and the lifting rod is located between the lever mechanism and the bracket, and a return spring is sleeved. The return spring can push the lever mechanism to move when the lifting mechanism falls, and make the locking mechanism contact the locking guide rail. The invention has the advantages of simple structure, reasonable design, low manufacturing cost, long continuous trouble-free operation period, high safety reliability, and low device cost, effectively preventing accidental injuries to operators due to equipment falling.

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
