Lifting device and construction method for replacing rake crane bridge

Abstract

The invention discloses a construction method for replacing a rake crane bridge, in particular an overhaul construction method suitable for the high and synchronous lifting of equipment with relatively complex structure, large equipment dead weight, large equipment three-dimensional size and relatively high spot elevation such as rake cranes. The construction method for replacing the rake crane bridge comprises the following steps of: using a lifting device positioned below a locked rake crane running bogie to integrally lift the rake crane running bogie away from bogie rails positioned on the rake crane bridge along a vertical direction, removing the rake crane bridge needed to be replaced, lifting and mounting a rake crane bridge for replacement on cart rails and connecting and mountingthe rake crane bridge for replacement in position, and finally returning the rake crane running bogie integrally to the bogie rails of the rake crane bridge after the replacement is completed along the vertical direction by using the lifting device.

Description

technical field [0001] The invention relates to a jacking device for replacing the bridge frame of a rake crane, in particular to a jacking device used in the technical field of metallurgical steel rolling hoisting equipment maintenance for equipment with heavy weight, high elevation and large three-dimensional size. lifting device. [0002] The invention also relates to a construction method for using the jacking device to repair or replace the bridge frame of the rake crane. Background technique [0003] As one of the important special equipment for the production of steel rails and steel rolling, the rake crane will directly affect the normal production of the factory. " method to dismantle, and then install according to the "bottom-up" method, the construction period of this kind of construction method is about 40-50 days, the construction period is long, the labor intensity is high, not only affects the production progress, but also seriously restricts the company dev...
