ANGLE MEASUREMENT APPARATUS FOR HOPPER PLATE

摘要

PURPOSE: An angle measuring device of a hopper plate is provided to measure the angles of various kinds of the hopper plates with one measuring device. CONSTITUTION: An angle measuring device (100) of a hopper plate comprises a body (110), a distance adjusting unit (120), and a measuring unit (130). The body includes: a horizontal plate (111); and a vertical plate (112) which is bent perpendicularly and extended from the horizontal plate. The distance fixing unit includes: a sliding bar (121) which is joined to be slid along the horizontal plate; a contact plate (122) which is in a face-contact with the surface of a girder joined to the lateral lower part of a tank top plate by being joined to one end of the sliding bar; a guide member (123) guiding the sliding bar to be slid; a fixing member (124) capable of fixing a position of the sliding bar; a cover plate (132) which is joined to a base plate by being slid in circular arcs to make one side of the cover plate be in contact to the outer lateral surface of the hopper plate corresponding to the outer lateral surface of the hopper plate; and a joining member joining the base plate and the cover plate to be slid.
