Hoisting structure for inner cone hole flange

Abstract

The invention discloses a hoisting structure of a flange with an inner tapered hole, which comprises a flange and a hoisting tool. The flange is provided with a bolt connection hole and a through hole; the lower part of the through hole is a tapered hole; the hoisting tool includes a suspension rod, a sleeve and multiple Group boom assembly; the sleeve is set on the boom, the upper end of the boom is provided with an upper handle, and the upper end of the sleeve is provided with a lower handle; the boom assembly includes a fixed rod, a matching rod and a connecting rod, the fixed rod and the sleeve Fixed connection, the two ends of the matching rod are respectively hinged with the fixed rod and the connecting rod, the two ends of the connecting rod are respectively hinged with the matching rod and the suspension rod, and the outer part of the matching rod is matched with the inner tapered hole of the flange; The flange with the inner tapered hole can be hoisted and transported through the cooperation of the hoisting tool with the inner tapered hole of the flange. The hoisting tool has a simple structure and is easy to operate, which improves the handling efficiency and avoids the crushing of the fingers. Improve the health of workers and reduce labor losses.
