Embodiment Construction
[0023] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0024] refer to figure 1 , the existing hoisting method for erecting the rolling mill archway is usually that the crane hook 1 adopts a steel wire rope-2 of equal length to directly hang on the outer lug 11 of the upper part of the rolling mill archway 10. During the lifting process, the equal-length steel wire rope-2 and the upper end of the rolling mill archway occur Dally, it is easy to be dangerous.
[0025] refer to figure 2 , image 3 with Figure 4 The structure of the erecting hanger for the rolling mill archway that the inventive method relies on is to include a hanger beam 3 arranged horizontally, on which a hanging shaft 5 is installed, and the hanging shaft 5 is used for hanging the steel wire rope. There are four sets in total in the longitudinal direction, among which two sets of hanging shafts 5 located inside the spreader...

The invention discloses a method for vertically hanging a rolling mill housing. The method comprises the following steps: step one, hanging one ends of four groups of steel wire ropes I with the equal length on a crane hook, hanging the other ends of two groups of hanging shafts on the inner side of a hanger beam, hanging two ends of two groups of steel wire ropes II with the equal length on two groups of hanging shafts on the outer side of the hanger beam, and mounting anti-drop plates I at two ends of the four groups of hanging shafts; step two, placing the rolling mill housing on the ground flatly in advance, cushioning a wood beam at the lower part of the rolling mill housing, and hanging the drooping middle parts of the two groups of steel wire ropes II with the equal length on two hanging lugs of the rolling mill housing; step three, during the vertical hanging process of the rolling mill housing and during the upward moving process of the crane hook, further moving the crane hook correspondingly in the rotation direction towards the upper end of the rolling mill housing till the rolling mill housing is vertically hung completely. The method provided by the invention is simple and easy to implement, and convenient to operate, thus obviously improving the safety.
Description
technical field [0001] The invention belongs to the technical field of heavy machinery installation equipment, and relates to a lifting method for erecting a rolling mill archway. Background technique [0002] The rolling mill arch is one of the key parts in the manufacturing of steel rolling equipment. Its weight is generally about 40-400T, and its height is generally about 8-16 meters. To achieve the erected state of the final work, since the archway is a heavy and high-height sheet-like component, its erection process has always been a very difficult problem. [0003] In order to reduce the workload after the erection of the rolling mill archway, the rolling mill archway will install the pressing mechanism and other components in advance when the rolling mill archway is laid flat, so it is usually impossible to lift from the middle and upper part of the rolling mill archway. The method of hanging on the hanging lugs outside the rolling mill archway, such as figure 1 As ...
