Description

A floor guide support structure

technical field

The invention relates to the technical field of steel rolling equipment, in particular to a floor guide support structure.

Background technique

The guide refers to the device installed before and after the roll pass to help the rolled piece enter and exit the roll pass accurately and stably according to the predetermined direction and state during the section steel rolling process.

The rolling mill in the rolling mill area of the bar and high-line production line workshop is generally equipped with a guide structure at the entrance and exit to assist the rolling mill in biting and rolling the rolled piece. The fixing of the guide is generally realized in two ways: one is the structure with a guide beam on the rolling mill, and the guide is directly installed on the rolling mill body; the other is a floor support structure, and the guide is supported by a floor guide The seat is fixed separately, and the center line of the guide and guard of this structure is fixed, which reduces the adjustment of the guide and guard on the production line and saves adjustment time.

The existing floor guide support is divided into two types: one is that the floor guide support and the bracket on which the guide is fixed are fixed. When changing the guide and rolling mill, it needs to be hoisted by the crane Guides and guide brackets are labor-intensive, labor-intensive and time-consuming; the other is: the guide support is fixed on the foundation, and the guide support can rotate around the rotation axis on the guide support. The guide with this structure The support structure is convenient for roll changing in the rolling mill, easy to use, and widely used. However, the second type of floor-to-ceiling rotating support has the following problems: when changing rolls in the rolling mill, the rotating opening of the guide support must meet the roll changing position of a rolling mill, the angle of rotation must be at least 90°, and the radius of rotation should not be too small. This will increase the distance between the rolling mills and affect the overall layout of the rolling process; during the rotation of the guides and brackets, they will interfere with the lower beam of the rolling mill, resulting in obstruction of the rotation; due to the harsh environment in the rolling mill area, the rotating shaft is often rusted and jammed , It needs to be completed manually with the crane when turning, which is laborious and time-consuming, and the work efficiency is low; the tipping moment of the guide during rolling is relatively large, and the rotating shaft of the hollow structure is easy to break.
