Installing method for oven protecting iron component for coke oven

Abstract

The invention provides an installing method for an oven protecting iron component for a coke oven. The method comprises the following steps: 1) an oven column and a protection board are separately transported into an operation table in the coke oven, the oven column and the protection board are fixed as a whole lifting module by using a special clamping tool, and the oven column is installed in alifting manner by adopting main crane and auxiliary crane structures; 2) a door frame is transported into the operation table, and the door frame is installed in a lifting manner by adopting the maincrane and auxiliary crane structures; and 3) an oven door is transported into the operation table, a special lifting tool is installed for the oven door, the special lifting tool and the oven door arecombined to form an integral lifting module, the module consisting of the oven door and the special lifting tool is placed on the operation table by using a main crane and an auxiliary crane, the auxiliary crane is removed, the top of the oven door is lifted by using a rotating base seat of the special lifting tool as a center to lift the oven door, and the oven door is lifted to the installationposition for installing and fixing. The oven protecting iron component provided by the invention is modularly assembled on the ground, and is installed through integrated lifting in place, so that the installation strength and installation safety risks are reduced, two cranes are cooperated, the moving speed of each module is well controlled, and the installation position can be straightened.

Description

technical field [0001] The present invention is a new construction technology, which relates to a kind of coke oven furnace body protective furnace iron parts, various equipment parts are assembled into installation modules on the ground workbench through special assembly tools and control means, and then installed in place in sequence Construction Technology. Background technique [0002] The construction of the coke oven body in foreign countries adopts the method of erecting the furnace column first. Before the coke oven is built, the iron parts such as the furnace column and the protective plate are installed; while in China, the construction technology of laying it first and then installing it is adopted. Firstly, the refractory material of the furnace body is built by masonry. After the masonry is completed, the various parts of the iron parts are installed in place one by one according to the design requirements. [0003] Due to technological progress and national po...

AI Technical Summary

Problems solved by technology

[0004] Using the above-mentioned foreign installation technology, the installation is very difficult and the installation cost is very high, which is unbearable for domestic construction units; especially the long construction period of installation cannot meet the construction period of domestic construction units at all.

[0005] The existing domestic technology is used for installation, the equipment components are complex, and the number of parts is large. The protection plate, furnace column, furnace door frame, furnace door, etc. are transported one by one and installed separately. The construction process is very complicated; the size of the iron parts is large. The weight is heavy, and the method of binding and single-point hanging is adopted during hoisting. During the hoisting process, the iron parts will have problems such as rotation and deflection, and the installation position cannot be corrected, which brings inconvenience to the installation of the iron parts and cannot meet the installation accuracy and construction period. During the installation, due to the inaccurate control of the position of the iron parts by the hoisting equipment and traction equipment, excessive force often causes damage to the iron parts, or the phenomenon that the iron parts hit the furnace body, resulting in the problem of high installation costs
