Example Embodiment

[0029] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0030] like Figure 1 to Figure 4 As shown, the present invention includes a pair of transverse plates 1, a piston rod clamping ring group 2 and an upper beam 3, and the two ends of the lower surface of the transverse plate 1 are respectively welded vertically with the circular tube 11, and the circular tube height H is smaller than the circular tube outer diameter D, The inner diameter d of the circular tube contains the outer diameter of the upper end 121 of the cylinder head stud. Such a structure enables the cross plate 1 to be firmly connected with the cylinder head studs 12, and can prevent the fastening screws 13 from being subjected to shearing force.

[0031] The piston assembly 4 includes a piston rod 41 and a piston 42 fixed on the upper end of the piston rod 41. The piston rod clamp ring group 2 includes a main pipe clamp 21, an auxiliary pip...

Abstract

The invention discloses a tooling and method for slantly lifting a piston assembly, comprising a pair of transverse plates, a piston rod grip ring group and an upper beam, wherein the piston rod grip ring group comprises a main pipe clamp, an auxiliary pipe clamp, two arc-shaped bushes, a plurality of struts and shackles, and chains with hooks; the arc-shaped bushes at the inner sides of the main pipe clamp and the auxiliary pipe clamp are used for clamping the upper part of a piston rod; when a piston assembly is slantly lifted, two ends of the upper beam are connected with the two ends of the main pipe clamp respectively by virtue of the chains with the hooks and the shackles; and a hook at the lower side of an engine-room crane is used for hooking the middle part of the upper beam. A method for slantly lifting the piston assembly disclosed by the invention comprises the steps that vertically lifting the piston assembly is vertically lifted and supported on the transverse plates, and the suspension center is dropped to the upper part of the piston rod, thus realizing the purpose of slantly lifting the piston assembly. The tooling disclosed by the invention is strong in universality, low in manufacture cost, simple and convenient to operate, and the problem that slant lifting needs of multiple diesel engine piston assemblies for ships are met through adoption of arc-shaped bushes of various specifications and struts is solved.

Description

technical field [0001] The invention relates to a lifting tool for a piston assembly of a marine diesel engine, in particular to a lifting tool and a method for obliquely lifting a piston assembly out of a main cylinder liner of a marine diesel engine, and belongs to the technical field of special lifting tools. Background technique [0002] The piston assembly is one of the main moving parts of the diesel engine and an important part of the combustion chamber. During the operation of the diesel engine, if there are problems such as wear, cracks and top ablation of the piston components in the cylinder, it will have a very bad impact on the working performance and service life of the diesel engine. Therefore, it is always necessary to ensure that the piston components of each cylinder are Good condition is very necessary. [0003] During the service period of the marine diesel engine, it is necessary to lift the piston assembly out of the marine diesel engine for related ma...
