Abstract

The invention relates to a caliper for a bevel edge distance of a membrane wall unit, which comprises a main scale with a measuring jaw; a scale body of the main scale with a measuring jaw is movably provided with a horizontal sliding seat; the horizontal sliding seat is provided with a horizontal positioning screw; a longitudinal sliding seat is fixedly arranged on the back side of the horizontal sliding seat; a longitudinal sliding scale is sleeved in the longitudinal sliding seat; the longitudinal sliding seat is provided with a longitudinal positioning screw; the bottom surface of the horizontal sliding seat is pressed against two measured steel pipes for determining a measuring direction; a raised head of an isosceles trapezoid of the longitudinal sliding scale is pressed against the inner sides of the two measured steel pipes for finding out the centers of the two measured steel pipes; the measuring jaw of the main scale with a measuring jaw is pressed against the bevel edge of a measured workpiece; and the distance between the bevel edge of the measured workpiece and the centers of the two pipes is read according to the alignment condition of the scale mark of the main scale with a measuring jaw and the frame line of the horizontal sliding seat.

Description

technical field [0001] The invention relates to a measuring ruler, in particular to a membrane wall unit bevel edge distance caliper for measuring the two-tube three-flat steel planer grooves of various plane membrane walls and cylindrical membrane wall units in the equipment manufacturing industry. Background technique [0002] Coal chemical industry is an emerging industry that uses coal and petroleum coke and other dry powder fuels as raw materials for gasification as coal-based chemicals, liquid fuels, combined cycle power generation, polygeneration systems, and hydrogen production systems. This industry will play an important role in the national economy. growing effect. The main equipment of coal chemical industry is the gasifier, which is composed of shell and internal parts. The internal parts are mainly composed of multi-section cylindrical water-cooled membrane walls, and the cylindrical membrane wall units are welded alternately by two round tubes and three f...
