Hydraulic type anti-sliding safe coupling device for hot rolling finishing straightening machine

Abstract

The invention discloses a hydraulic type anti-sliding safe coupling device for a hot rolling finishing straightening machine. The device sleeves a transmission shaft and comprises an outer ring steelsleeve, an inner steel sleeve and a hydraulic mechanism, the inner steel sleeve is arranged on the outer side of the transmission shaft, the outer ring steel sleeve is arranged on the outer side of the inner steel sleeve, the position between the outer ring steel sleeve and the inner steel sleeve is provided with filling abrasive, one end of the outer ring steel sleeve is connected to a spindle through a fastening bolt, the spindle is connected with the transmission shaft through a dedicated bolt, and a nut, the hydraulic mechanism comprises a positioning device, a hydraulic adjusting block, oil nozzles and a pressing ring, the positioning device is connected with the other end of the outer ring steel sleeve through a thread structure, a hydraulic cavity is formed in the positioning device, the hydraulic adjusting block is mounted in the hydraulic cavity, the oil nozzles are connected to the positioning device, and communicate with the hydraulic cavity, the pressing ring sleeves the other end of the inner steel sleeve, and is in contact with the hydraulic adjusting block, the phenomenon that an anti-sliding safe coupling for an original finishing straightening machine is too high in repair cost can be avoided, and the hydraulic type anti-sliding safe coupling device for the hot rolling finishing straightening machine facilitates low-cost maintaining and replacing.

Description

technical field [0001] The invention relates to an anti-slip safety handle on a hot-rolling finish leveler, and more specifically relates to a hydraulic anti-slip safety handle device for a hot-rolling finish leveler. Background technique [0002] The purpose of the hot-rolled finishing production line is to perform heat treatment processes such as quenching, high-temperature normalizing, and tempering on the steel plate to improve the physical properties of the finished steel plate and meet the higher performance requirements of special users. The last process of this line is to straighten the steel plate after heat treatment, so as to obtain the delivered plate shape that meets the specifications and user requirements. Therefore, at present, the hot rolling and finishing production lines of domestic and foreign iron and steel enterprises all use the core equipment leveler. [0003] In order to meet a wide range of plate thickness straightening (3mm to 12mm), the existing ...

Problems solved by technology

[0009] Therefore, it is not worth much to repair the safety receiver according to the original structure at present. Generally, the principle of scrapping is adopted to replace the new safety receiver parts, which increases the cost of spare parts maintenance.
