Thickness gauge for rolling mill and running gear of thickness gauge

Abstract

The invention discloses a running gear of a thickness gauge for a rolling mill. The running gear comprises a rack (1), a gear (2) and a running motor (3), wherein the rack (1) is arranged along the horizontal direction; the gear (2) is meshed with the rack (1); the running motor (3) is used for driving the gear (2); one of the rack (1) and the running motor (3) is fixed on a frame (4) of the rolling machine; and the other one of the rack (1) and the running motor (3) is fixed on the thickness gauge (5) for the rolling mill. In the running gear of the thickness gauge for the rolling mill, a gear rack pair structure consisting of the rack (1) and the gear (2) is used for driving, so the thickness gauge (5) for the rolling mill can run in the horizontal direction, the problem of running instability caused by the cylinder push running mode in the prior art is effectively solved, the running characteristic of the thickness gauge (5) for the rolling mill is optimized, the thickness measuring precision is improved and the product quality is improved. The invention also discloses the thickness gauge for the rolling mill, which adopts the running gear.

Description

technical field [0001] The invention relates to the technical field of rolling mills, in particular to a rolling mill thickness gauge and a traveling device thereof. Background technique [0002] Rolling mill is the equipment that realizes the metal rolling process. It generally refers to the equipment that completes the whole process of rolling material production, including main equipment, auxiliary equipment, lifting and transportation equipment, and auxiliary equipment. A thickness gauge is an instrument used to measure the thickness of an object. It is commonly used in industrial production to continuously measure the thickness of products (such as steel plates, steel strips, paper, etc.). [0003] The walking mode of the existing rolling mill thickness gauge is the driving mode driven by the cylinder. The disadvantage of the cylinder is that many factors such as the stability of the air pressure, the load situation and the walking road condition will affect the unifor...

Problems solved by technology

[0003] The walking mode of the existing rolling mill thickness gauge is the driving mode driven by the cylinder. The disadvantage of the cylinder is that many factors such as the stability of the air pressure, the load situation, and the walking road conditions will affect the uniformity and stability of the walking.

[0004] Therefore, the cylinder of the existing thickness gauge is pushed to walk, and many unfavorable factors cause the air pressure to be unstable, causing the thickness gauge to jog forward during the walking process, and the walking cannot be positioned accurately; in addition, the stroke of the rolling mill thickness gauge is about 1.5 meters, and the stroke of the cylinder is relatively long , and the cylinder is small, the piston rod is slender, and the cylinder pushes and walks, which brings a lot of inconvenience to daily maintenance

[0005] Therefore, how to solve the problem that the rolling mill thickness gauge is not in place and shaking and unstable during the production process, so as to avoid the impact on the rolling mill production, has become an important technical problem to be solved urgently by those skilled in the art
