The invention provides an auxiliary device used for repair and maintenance of a finishing mill, and belongs to the technical field of repair and maintenance of steel rolling equipment. The auxiliary device used for repair and maintenance of the finishing mill comprises two fixing bases, two mounting frames, two clamping mechanisms, and a plurality of rolling assemblies, wherein the two fixing bases are arranged on opposite clamping heads of connecting shafts of the finishing mill, the two mounting frames are symmetrically arranged on the two fixing bases, and the clamping mechanisms are in rolling contact with roller end shaft sleeves of the finishing mill through the rolling assemblies; a first linear driving mechanism is arranged on each mounting frame; the clamping mechanisms are in one-to-one correspondence with the first linear driving mechanisms and are driven by the first linear driving mechanisms to clamp the roller end shaft sleeves of the finishing mill; and the rolling assemblies are detachably mounted on clamping parts, in contact with the roller end shaft sleeves of the finishing mill, of the clamping mechanisms. According to the auxiliary device used for repair and maintenance of the finishing mill, repair of a turning gear of a speed reducer and maintenance of the interior of the finishing mill can be conducted at the same time without disassembling the connecting shafts, no crane is needed, the preparation time for repair and maintenance of the finishing mill is shortened, the working efficiency is improved, and the application range is wide.
Description
technical field [0001] The invention belongs to the technical field of steel rolling equipment repair and maintenance, and more specifically relates to an auxiliary device for repair and maintenance of a finishing mill. Background technique [0002] Finishing mill roll end shaft sleeve, one end is connected with the roll, and the other end is connected with the finishing mill shaft through the shaft clamping device, forming a transmission system. When replacing the roll, the shaft clamping device clamps the sleeve of the roll end to fix it on the shaft, and the sleeve of the roll end can be disengaged from the roll without falling into the pit. [0003] Both the reducer of the finishing mill and the inside of the finishing mill need regular maintenance. During the maintenance of the reducer, the reducer needs to be turned. During the turning process, the rolls, roll end bushings and the connecting shaft of the finishing mill are required to be kept connected to form a transm...
