Abstract

The invention discloses an angle measurement device used for a distribution chute of a blast furnace. The blast furnace is provided with a manhole. The angle measurement device comprises a base, a vertical support column, a rotary adjustor, a laser range finder and an angle ruler, wherein the rotary adjustor sleeves a proper position on the outer surface of the vertical support column, and is usedfor rotating the vertical support column to adjust the position of the vertical support column; the laser range finder is hinged to the top of the vertical support column, and used for enabling at least two beams of laser to penetrate through the manhole and to be emitted onto the outer surface of the distribution chute to accurately measure and adjust a distance between the laser range finder and the distribution chute, so that the laser range finder is parallel to a vertical plane which penetrates through the central line of the distribution chute; and the angle ruler is used for measuringan angle between the laser range finder and the vertical support column to obtain the degree of an included angle between the central line of the distribution chute and the vertical direction. The invention further provides an angle measurement method used for a distribution chute of a blast furnace. The angle measurement device and the angle measurement method used for the distribution chute of the blast furnace are capable of increasing the measurement accuracy for the equal angle of angle alpha of the distribution chute, and further capable of improving the working safety.

Description

technical field [0001] The invention relates to the technical field of blast furnace auxiliary equipment in the metallurgical industry, in particular to an angle measuring device and an angle measuring method for a blast furnace material distribution chute. Background technique [0002] The bellless top is the key equipment of medium and large blast furnaces, and the bellless charging refers to the system that uses the top charging equipment to realize the charging. In the bellless furnace top, the function of the distribution chute is to change the angle α between the center line of the distribution chute and the vertical direction perpendicular to the ground, and the angle of the projection β angle of the center line of the distribution chute in the horizontal direction. Realize cloth at any position in the blast furnace, such as figure 1 shown. [0003] Most of the distributing chutes adopt an integral assembly structure and are installed on the tilting control equipmen...
