Device for itinerantly measuring blast furnace charge level

Abstract

The invention relates to a device for itinerantly measuring blast furnace charge level, belonging to the technical field of blast furnace measurement. The device comprises a radar gage rod, a special section screw rod, upper limit, a lifting sliding rod, an inclined rod, lower limit, a fixed bracket, a motor, a linking bearing, helical teeth, a connecting shaft, a bearing and a spiral groove; wherein the radar gage rod is installed on the inclined rod which can rotate around a point on the fixed bracket, a right-angle triangle is formed by the inclined rod, the special section screw rod and the fixed bracket, and the fixed bracket is one side of the triangle and fixed with the surrounding objects; the special section screw rod is another vertical side of the triangle, the motor installed on the fixed bracket drives the lifting sliding rod to move up and down by the special section screw rod so as to push the inclined rod and the radar gage rod arranged on the inclined rod to rotate, stop and rotate, and the radar gage rod can be used for continuously measuring measure points; the distance between different points of the charge level along the radial direction of a blast furnace on the same vertical surface with the radar gage rod and a distance meter can be continuously measured, and the distribution curve of the blast furnace charge level and the descent velocity of furnace charge are calculated. The device has the advantage that a device can measure the distribution shape of the furnace charge along the radial direction of the blast furnace and the descent velocity thereof.

Description

technical field [0001] The invention belongs to the technical field of blast furnace detection, and in particular provides a device for itinerantly measuring the blast furnace material level, capable of iteratively measuring the radial distribution shape of the blast furnace material level, and can be applied to continuous measurement and on-site detection in various industries and fields. Background technique [0002] The ways and methods to measure the position of objects on site mainly include manual measurement and measurement using laser, radar and other measuring equipment. It seems powerless for the out-of-reach position. Although people can solve some of the above problems by adjusting the angle of the measuring tool, the accuracy of the measurement results is greatly reduced due to the well-known problem of angle measurement accuracy, and its reliability is also greatly reduced. [0003] At present, the measurement method of the charge level of blast furnace is mai...
