Abstract

The invention discloses a rapid replacement device, system and method for a withdrawal and straightening machine, relates to the technical field of withdrawal and straightening machine replacement, and is used for solving the problems that an existing continuous casting withdrawal and straightening machine is difficult to disassemble and assemble, inconvenient to install and position, complicatedin online replacement. The device comprises a hydraulic locking mechanism and an alignment mechanism, wherein the hydraulic locking mechanism comprises a hydraulic cylinder fixed onto a base; the hydraulic cylinder is connected with a connector; the connector is nested into a connecting flange hole; a connecting flange is connected with a near-end sliding block; the other side of the near-end sliding block is connected with a guide rod; the guide rod transmits a push-pull force of the hydraulic cylinder to a far-end sliding block; the alignment mechanism comprises a cross beam; and a pin shaftand a positioning pin are arranged on the cross beam. The system comprises the withdrawal and straightening machine and the rapid replacement device for the withdrawal and straightening machine. Themethod is implemented by adopting the system. The rapid replacement device, system and method for the withdrawal and straightening machine provided by the invention can better realize the functions onconveniently disassembling and assembling the withdrawal and straightening machine as a whole, accurately installing and positioning, replacing online and the like.

Description

technical field [0001] The invention relates to the technical field of tension leveler replacement, in particular to a quick replacement device, system and method for tension leveler. Background technique [0002] The tension leveler is the key equipment in the continuous casting production, which is closely related to the operating rate of the continuous casting machine. At present, domestic steel mills generally have problems such as high intensity and long time-consuming replacement of tension leveling machines, which have a great impact on the continuous casting operation rate and the overall production capacity of the casting machine. The specific performance is: [0003] First, it is difficult to disassemble and assemble: the base and beam of the conventional five-roller tension leveler are connected and fastened by pins and wedges. Due to the accumulation of iron scale on site, water vapor corrosion and other reasons, manual disassembly is difficult, and even cuttin...
