Equipment for measuring internal size of steel ladle by using laser range finder and operation method thereof

Abstract

The invention relates to equipment for measuring the internal size of a steel ladle by using a laser range finder and an operation method thereof. The equipment comprises a laser range finding mechanism and a bunching mechanism, and a side connection guardrail frame is arranged at the bottom end of the laser range finding mechanism. The beneficial effects of the equipment are that: According to the equipment for measuring the internal size of the steel ladle by using the laser range finder and the operation method thereof, the size condition of any area in the steel ladle can be measured, theinternal condition of the steel ladle can be simply simulated, the melting loss degree of the area is judged by comparing with relevant parameters when the steel ladle is on line, the internal condition of the steel ladle can be simply simulated through the method, the refractory material melting loss degree of the steel ladle and the steel weighing amount condition of the steel ladle can be calculated, and an original method for optimizing manual measurement by using the rod is adopted; finally, ladle service monitoring and ladle lining size control data and information can be provided for steel ladle service monitoring, a foundation is laid for saving refractory material consumption and prolonging the ladle life, major accidents of steel ladle furnace penetration are effectively prevented and safe operation and smooth production of steel ladle service are guaranteed.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a device for measuring the internal dimensions of a steel ladle by using a laser range finder and an operation method thereof. Background technique [0002] At present, the internal size measurement tool of the ladle is the LTG ladle lining measuring instrument. The measuring principle is: by emitting a pulsed laser beam to the lining surface of the steel ladle to be tested, and receiving the returned laser to measure its flight time, and then calculate it according to the transmission speed of the laser. The distance between the device and the target point. When measuring, the user pushes it to a certain position on the platform in front of the ladle. After the equipment performs rapid self-positioning, it can start to scan and measure the target area of ​​the ladle. During the measurement, the laser head of the equipment rotates at a certain step angle. By quickly changing...

Problems solved by technology

[0003] Ordinary equipment has high measurement costs and high daily maintenance costs. A laser rangefinder costs about 1 million yuan, and the monthly maintenance cost is about 10,000 yuan. However, there is a measurement method in the prior art that is a pole structure measurement method. This tool It is composed of an upper pole and a lower pole. The front ends of the upper pole and the lower pole are respectively equipped with symmetrically inclined measuring feet, and the rear ends of the upper pole and the lower pole are respectively equipped with symmetrically inward inner angle measuring plates. The lengths of the rods are equal, and the hinge points of the second half are hinged to each other through the hinged device, which has the disadvantage of heavy measuring equipment, which requires 4 to 5 people to operate at the same time during the measurement, and the measurement accuracy is low
