A laser rangefinder protection device

Abstract

The invention discloses a protection device for a laser range finder, comprising an air intake hood arranged outside the laser range finder and an air curtain pipe installed at the front end of the air intake hood, wherein the air intake hood can circulate cooling air , when the gas in the air curtain duct flows out of the air curtain duct, a dust-proof air curtain can be formed at the air outlet channel at the front end of the air inlet cover. The laser range finder protection device provided by the present invention realizes cooling and dust removal of the laser range finder through the design of the dust cover and the air curtain pipe, ensures the accurate positioning of the laser range finder, and prolongs the laser range finder. The maintenance cycle of the distance meter protection device provides a safety guarantee for automatic tapping.

Description

technical field [0001] The invention relates to the protection field of laser range finder, in particular to a laser range finder protection device. Background technique [0002] When tapping in a steel plant, an automatic tapping system is generally used. Through comprehensive detection methods, mathematical models and automatic control technology, the automatic tilting of the converter and the automatic follow-up of the ladle car are realized to achieve the automation of the tapping process. In the actual automatic tapping process, the follow-up function of the ladle car depends on the accuracy of the positioning system of the ladle car, which directly determines the success or failure of automatic tapping. [0003] During the movement of the ladle car, a laser range finder is generally required for position detection. In the prior art, the air intake cover of the laser range finder generally has the problem that the mirror surface of the range finder is easily stained wit...

AI Technical Summary

Problems solved by technology

[0003] During the movement of the ladle car, a laser rangefinder is generally required for position detection. In the prior art, the air intake cover of the laser rangefinder generally has the problem that the mirror surface of the rangefinder is easy to be stained with dust. The value of the laser rangefinder has no effect, but in special environments (such as: near ladle trucks and slag trucks), slag falling and splashing are frequent, accompanied by a large amount of dust. At this time, the front end of the laser rangefinder cannot be protected. It is easy to cause a large amount of dust accumulation on the mirror surface, which seriously affects the positioning accuracy of the laser rangefinder and shortens the maintenance cycle
