Abstract

The application provides a mandrel hoisting mechanism, which belongs to the field of mechanical equipment. It includes a support frame; a connecting frame, one end of which is connected to the top of the supporting frame at an angle; lifting lugs, which are installed on the connecting frame; lifting components, including arc-shaped limiting plates and two positioning plates, two The positioning plate is installed on the upper surface of the arc-shaped limiting plate at intervals in parallel; the arc-shaped limiting plate bends away from the positioning plate, and two connecting grooves are arranged at intervals on one side of the arc-shaped limiting plate, and There are two bolt holes at intervals on one side; the bottom of the support frame is installed between two positioning plates; the hydraulic cylinder is installed on the support frame, and the drive end is connected to the upper surface of the arc-shaped limit plate superior. The device is easy to operate, has strong stability, is convenient to use, and has high safety performance.

Description

technical field [0001] The present application relates to the field of mechanical equipment, in particular to a mandrel hoisting mechanism. Background technique [0002] The mandrel of the coiler in the hot rolling mill is an important production equipment. It must be replaced after a period of use (usually about 50 days). Due to the irregular shape of the mandrel and the limitation of the hoisting space, it is necessary to replace the mandrel. Here comes great trouble. In the past, the steel wire rope was used for hoisting, not only the mandrel was easily damaged, but also the mandrel was tilted during hoisting, and it would slide and collide with the surrounding equipment, causing damage to the mandrel and other equipment, and it may slip and fall off the wire rope, which is prone to safety accidents . Contents of the invention [0003] One of the purposes of the present application is to provide a mandrel hoisting mechanism, aiming to improve the existing problem of l...
