[0002] With the rapid development of the steel industry, furnace drying equipment has a very broad application prospect. Scientific and technological personnel have developed a new type of internal combustion furnace drying device, which can use diesel, natural gas or coke oven gas as fuel. The hot air generated by it has a good furnace drying effect. During the installation of the furnace drying facility, the furnace drying facility needs to be jacked up; during the jacking installation of the existing furnace drying facilities, four hydraulic cylinders are generally used to jack up the four corners of the bottom of the jacking plate, and the lower middle part of the jacking plate is in an empty state, resulting in unbalanced force, which can easily cause the furnace drying facility to tip over and be damaged. Therefore, we have introduced a new jacking device for furnace drying facilities. Utility Model Content
