A simulation positioning device and positioning method for adjusting steel plate blowing nozzle

Abstract

The invention relates to an analog positioning device for adjusting a blowing nozzle of a steel plate. The device comprises a laser device, a laser device holder, an externally-installed fixing protection sleeve, a guide pin and a positioning block, wherein an inner cylindrical hole is formed in one side of the laser device holder, the laser device is installed in the inner cylindrical hole, the guide pin which is in integral structure with the laser device holder is arranged on the other side of the laser device holder, a triangular positioning block is arranged outside the guide pin, and theexternally-installed fixing protection sleeve is arranged outside the laser device holder; and the analog positioning device is installed at the front end of the blowing nozzle of the steel plate, the guide pin is inserted into an inner hole of the nozzle for positioning treatment, a nozzle head is sleeved with the externally-installed fixing protection sleeve, the triangular positioning block isinstalled in a spraying groove of the nozzle, and the nozzle is adjusted according to the field condition. According to the positioning device and the positioning method, the nozzle installation position and angle is accurately positioned, so that the analog positioning treatment and the quick adjustment can be realized without a working medium.

Description

technical field [0001] The invention relates to metallurgical equipment, in particular to a simulation positioning device and a positioning method for adjusting a steel plate blowing nozzle. Background technique [0002] In the past, the adjustment of the nozzle angle and position generally used to confirm the nozzle angle and position by observing the actual spraying state after sending the medium. In this way, it is necessary to pre-adjust the nozzle in advance, and the precise positioning of the nozzle can only be realized after the medium is sent out. In this way, not only the work procedure is cumbersome, but also due to objective reasons such as the harsh environment of the on-site operation, the position of the nozzle adjustment is limited by the position of the equipment after the operation, etc., it is difficult to adjust the nozzle. Individual outlet nozzles are located in equipment with high radiation such as X-rays and convexity meters that are harmful to the hum...

Problems solved by technology

In this way, not only the working procedures are cumbersome, but also due to the harsh environment of the on-site operation, the adjustment position of the nozzle is limited by the position of the equipment after the operation and other objective reasons, making the adjustment of the nozzle more difficult.

Individual outlet nozzles are located in equipment with high radiation that is harmful to the human body such as X-rays and crown meters, and cannot be adjusted online. The nozzles can only be adjusted after the X-rays and crown meters are opened.

Due to the narrow space for nozzle installation and adjustment, the feet must be stepped on the roller table during the adjustment process, and there are moving equipment such as water cutting boards around, which cannot guarantee the safety of the adjustment personnel.

To ensure the safety of personnel, it is necessary to cut off the power to the roller table and close the valve of the water cutting plate. This adjustment takes nearly an hour. Some nozzles are at the exit of the rolling mill, and they are often blocked by dust. They need to be disassembled every time they are overhauled. ,Adjustment

It is necessary to send the medium one hour in advance for each maintenance, and repeatedly adjust the nozzle at this position, which is time-consuming and labor-intensive and cannot be adjusted quickly
