Lifting appliance turnover device for lifting tubular pile

Abstract

The invention relates to the field of tubular pile machining, in particular to a lifting appliance turnover device for lifting a tubular pile. The lifting appliance turnover device for lifting the tubular pile is characterized in that a turnover air cylinder is fixed onto a suspension frame through an air cylinder bolt; one end of a turnover piston rod is connected with a U-shaped connecting platethrough a hinge; the U-shaped connecting plate is connected onto a lifting hook fixing plate through a rotating shaft and a bearing; the lifting hook fixing plate is welded to the lower end of the suspension frame; one side of the U-shaped connecting plate is connected with a lifting hook connecting frame; the lifting hook connecting frame is connected with the lifting hook fixing plate through apin; the lifting hook fixing plate is fixed onto a grabbing hook air cylinder through a grabbing hook fixing bolt; the hook fixing plate is sleeved with an upper grab hook and a lower grab hook through a lower grab hook shaft and an upper grab hook shaft respectively; the lower grab hook shaft and the upper grab hook shaft are provided with an upper grab hook gear and a lower grab hook gear respectively; a lower grab hook fixing plate is fixedly connected with the lower grab hook gear and the lower grab hook; the upper grab hook fixing plate is fixedly connected with the upper grab hook gearand the upper grab hook; and a grab hook control plate is welded with the upper grab hook. Due to the adoption of the technical scheme, the lifted tubular pile can be grabbed and released freely, transferred safely and turned over freely.

Description

technical field [0001] The invention relates to the field of processing pipe piles, and relates to a lifting tool turning device for hoisting pipe piles. Background technique [0002] At present, the transfer tools for hoisting pipe piles are all single hoisting and transfer. For some pipe piles, there is no spreader that can not only hoist, transfer, automatically pick and place, but also turn over. Contents of the invention [0003] The object of the present invention is to provide a hanger turning device for hoisting pipe piles. [0004] The present invention is realized in the following way: a hanger overturning device for hoisting pipe piles, which is characterized in that the overturning cylinder is fixed on the suspension frame with cylinder bolts, and one end of the overturning piston rod is connected to a U-shaped connecting plate with a hinge, and the U-shaped connection The plate is connected to the hook fixing plate with a rotating shaft and a bearing, the hoo...
