Omni-directional adjustable rapid abutting-connection device and method of slag-breaking machine installed on large gasifier in coal chemical industry

Abstract

The invention relates to an omni-directional adjustable rapid abutting-connection device of a slag-breaking machine installed on a large gasifier in the coal chemical industry. The omni-directional adjustable rapid abutting-connection device of the slag-breaking machine installed on the large gasifier in the coal chemical industry comprises a carrying vehicle frame body, wherein four corners of the bottom of the carrying vehicle frame body are respectively provided with a rail wheel with a braking disc, the carrying vehicle frame body is welded to a base plate, a carrying plate is arranged above the base plate, three supporting frames evenly distributed on the carrying plate are respectively provided with a hydraulic lifting jack, a rotary mechanism is arranged between the carrying plate and the base plate and comprises three or more sleeve bodies or roller bodies, the sleeve bodies are installed on the base plate, the roller bodies are arranged on the sleeve bodies, and the carrying plate is supported on the roller body and is in a rolling friction state. A plurality of rolling balls are arranged between the base plate and the carrying plate, so that rolling friction is formed between the base plate and the carrying plate, and the carrying plate can rotate or move horizontally on the base plate. Therefore, fine adjustment of the abutting-connection device is achieved, large equipment does not need to be used, manpower is saved, and work efficiency is improved.

Description

technical field [0001] The invention relates to the field of coal chemical industry, in particular to an all-round adjustable fast docking device for installing a slag breaker in a large gasification furnace used in the coal chemical industry. Background technique [0002] The slag breaker is located between the bottom of the quenching chamber of the gasifier and the lock hopper. Its function is to break the oversized slag or fallen refractory bricks, so as to ensure the smooth slagging and continuous operation of the gasifier for a long time. The shell of the slag breaker is a three-type pressure vessel, and a crushing device is designed inside to break the slag continuously produced by the gasifier and prevent unbroken objects from collecting on the shaft. [0003] The slag breaker is installed on the bottom of the gasifier through the flange, and there are multiple bolt holes on the flange. When installing, the slag breaker is usually lifted to the matching height,...

AI Technical Summary

Problems solved by technology

However, there are dozens of bolt holes evenly distributed on the upper flange of the slag breaker and the lower flange of the gasifier. It is necessary to ensure that each pair of holes in the main engine of the slag breaker and the bottom flange of the quenching chamber of the gasifier are quickly aligned before they can be connected. If the alignment is not accurate, the main engine of the slag breaker and the mobile trailer can only be moved out together, and then roughly adjusted in the horizontal direction by a hoisting machine. The re-testing of the flange connection generally needs to be repeated at least 4-5 times, and it takes more than a day to complete the docking requirements of a set of equipment. At the same time, large-scale lifting equipment and multiple types of personnel are required to coordinate operations, and the installation efficiency is low. Waste time and manpower, affect the installation or maintenance period
