Abstract

The invention provides an installation method for avoiding interference when the rolling mill rack is lifted. The method: according to the interference position of the interference rack to be hoisted, determine the height difference between the two transport vehicles transporting the two ends of the rack to be hoisted, and Make two transport carts; hoist the rack to be hoisted on the two transport carts, and use the two transport carts to support the two ends of the hoisting mechanism, so that the rack to be hoisted will give way to the interference part; The transport vehicle traverses the rack to be hoisted to the installation position; jacks up the rack to be hoisted. The present invention supports and transports the rack to be hoisted by two transport vehicles with height difference, so that the rack to be hoisted is arranged obliquely, thereby avoiding the interference of the interfering parts when the rack to be hoisted is lifted and installed, so as to solve the problem of two rolling mills If the stand spacing is too short to make installation impossible, the efficient installation of rolling mill stands under restricted conditions is realized, the number of jacking times is reduced, and the hoisting 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 ...
