Abstract

The invention provides a mounting method for preventing rolling mill housings from interfering during lifting. The method comprises the followings steps that according to an interference part of an interference to-be-lifted housing, the height difference between two transport vehicles for transporting the two ends of the to-be-lifted housing is determined, and the two transport vehicles are manufactured; the to-be-lifted housing is lifted to the two transport vehicles, the two ends of the to-be-lifted mechanism are supported through the two transport vehicles so that the to-be-lifted housing recedes for the interference part; the to-be-lifted housing is transversely moved to a mounting position through the two transport vehicles; and the to-be-lifted housing is lifted. According to the method, the to-be-lifted housing is supported and transported through the two transport vehicles with the height difference, so that the to-be-lifted housing is obliquely arranged, then the interference part is prevented from interfering in lifting and installing of the to-be-lifted housing, so that the situation that the two rolling mill housings cannot be installed due to the fact that the interval between the two rolling mill housings is too short is solved, the high-efficiency installation of the rolling mill housings under the limited condition is realized, the lifting frequency is reduced, and the lifting time is shortened.

Description

technical field [0001] The invention relates to the technical field of metallurgical machinery installation, in particular to an installation method for avoiding interference when a rolling mill stand is lifted. Background technique [0002] At present, in the construction of metallurgical steel rolling projects, the installation of large rolling mill racks in a limited space needs to be realized by hydraulic jacking devices. [0003] see figure 1 , which is a structural schematic diagram of the hoisting of the rolling mill stand in the prior art. As shown in the figure, during the hoisting process of the rolling mill frame using the hydraulic jacking device 1', it was found that due to the short distance between the frames on both sides, the installed frame 2' was installed on the frame base 4', and the trolley 3' will After the rack 5' to be hoisted moves to the installation position, when using the hydraulic jacking device 1' to lift the rack 5' to be hoisted, the head ...
