Abstract

The invention relates to the technical field of lifting equipment, and discloses a lifting device. The lifting device comprises a lifting piece, a first sleeve, a second sleeve, a first fastener and a second fastener; the lifting piece comprises a lifting plate and a lifting arm which are connected; the lifting arm is used for being connected with a crane; the first sleeve is used for being in threaded connection with a first cylinder cover bolt of a cylinder cover to be lifted; the second sleeve is used for being in threaded connection with a second cylinder cover bolt of the cylinder cover to be lifted; the first fastener is used for being detachably connected with the lifting plate and the first sleeve; and the second fastener is used for being detachably connected with the lifting plate and the second sleeve. The lifting device provided by the invention has the advantages of high lifting safety, high lifting efficiency, no need of machining a lifting hole in an existing cylinder cover, adjustable lifting acting force applying position and low lifting cost.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a lifting device. Background technique [0002] The arrangement of the cylinder heads on the top of some types of low-speed diesel engines is very different from that of traditional low-speed diesel engines, which makes the layout of the spreader very difficult. When installing the spreader, it is necessary to remove the cylinder heads, cylinder head bolts, exhaust After the air valve, fuel injector start valve and various oil pipes and other components are installed, the crankshaft is turned to a specific position with a barring machine so that the piston is lower than the cylinder liner, and then the spreader can be installed. In particular, the installation and disassembly of the cylinder head bolts is cumbersome, and a hydraulic tensioner is required to apply pre-tightening force to the cylinder head bolts, and the oil pressure of the hydraulic pump of the hydraulic...
