Problems solved by technology

At this time, the stress surface of the pipe brick changes, cracks will appear in the mortar joints, and even the bricks will fall off, which will easily cause the cylinder body of the rising pipe to burn through, causing the leakage of raw gas and causing great environmental pollution.

Abstract

The invention provides a modular mounting device and method for a riser lining of a coke oven. The modular mounting device comprises an annular brickwork mounting vehicle, wherein the annular brickwork mounting vehicle mainly comprises a construction vehicle, a jib crane and an annular brickwork lifting appliance; the jib crane is connected to the construction vehicle; the annular brickwork lifting appliance is connected to the jib crane, and the annular brickwork lifting appliance clamps a built annular tube brick; the jib crane hoists the annular brickwork lifting appliance and tube bricks to a proper position together; the construction vehicle comprises a frame and a platform; the platform is horizontally mounted on the frame; and an opening matched with the radian of a pipeline of a riser is formed in one side of the platform. During use, the annular brickwork mounting vehicle is pushed to a riser placing place, and an upper-layer brick joint and a lower-layer brick joint are marked in a staggered manner; the tube bricks are built, and an expansion joint material is bound; the annular brickwork lifting appliance is combined with the annular tube brick; and the tube bricks are hoisted and mounted. According to the modular mounting device and method, vertical placement and building of the riser are achieved, meanwhile, constructors can complete building of the tube bricks outside the riser, the operation difficulty of building the riser lining is reduced, and the operation efficiency is improved.

Description

technical field [0001] The invention belongs to the installation technology of coke oven process equipment for high-temperature raw gas in a carbonization chamber, and in particular relates to a modular installation device and an installation method for lining of coke oven rising pipes. Background technique [0002] The rising pipe is installed on the roof of the coke oven, and is a coke oven process equipment used to lead out the raw gas in the carbonization chamber. Due to the small diameter of the riser tube body and the narrow and long pipe body, the lining masonry needs to rely on small and thin construction workers to enter the riser pipe for masonry. In order to avoid setting up scaffolding construction, the conventional method is to place the rising pipe horizontally, and the construction personnel lie down on the inside of the rising pipe for lining masonry, and then turn the rising pipe to a vertical state. At this time, the stress surface of the pipe brick change...
