Hook head device of working roller changing hauling mechanism

Abstract

The invention discloses a hook head device of a working roller changing hauling mechanism. The hook head device includes a support, a fastener, a stop block, a push stop pressing block and a fastener arm; the support is concave; a back end of the fastener is connected to the support through a pin shaft; a groove is formed in one end of the pin shaft; the stop block is fixed on one side of the support, and is embedded in the groove formed in the pin shaft; the fastener arm is fixedly connected to a back end of the top of the fastener, and forms an L-shaped structure with the fastener; a hook head is arranged on the front end of the fastener; the push stop pressing bock is fixedly arranged on the front end of the top of the support, is pressed against the front end of the fastener arm, and is used for pushing and stopping the fastener arm so as to connect the hook head arranged on the front end of the fastener and a working roller. The hook head device can rapidly complete a connection between a roller changing hauling mechanism and the working roller.

Description

technical field [0001] The invention relates to a traction mechanism for changing work rolls of a four-high reversible hot rolling roughing mill, more specifically, to a hook head device for replacing work roll traction mechanisms. Background technique [0002] The four-bar reversing hot rolling roughing mill in the metallurgical industry is a highly efficient and energy-saving hot continuous rolling equipment. The hook head device of the roll changing traction mechanism is a connection device responsible for pulling out and loading the upper and lower work rolls of the four-roll reversible hot rolling roughing mill from the rolling mill archway. At present, the hook head device of the roll change traction mechanism in the roll change device of the domestic four-roll reversible hot rolling roughing mill adopts an integral concave-convex connection mode. When the four-roll reversible hot-rolling roughing mill performs upper and lower work roll replacement, the convex hook he...

Problems solved by technology

[0003] However, the roll change method of the upper and lower work rolls of the four-bar reversible hot rolling roughing mill, as a way of pulling and loading the work rolls from the rolling mill archway, is evaluated from the perspective of improving production efficiency and reducing operating intensity. It takes a long time and the difficulty of interlocking the unevenness of the lifting hook head is high, and there are great safety hazards in the on-site operation
