Problems solved by technology

[0003] At present, the installation and disassembly of the hydraulic tensioner are all done manually by the operator, so the volume and weight of the tensioning tool used for PC2-6 diesel engine cylinder head studs will directly affect the heavy and convenient work of the operator
The existing stretching tool is an eight-unit type, that is, 8 independent hydraulic tensioners are fixed on a disc according to the distribution position of the cylinder head nut, and the height of the disc must be higher than the valve on the cylinder head The height of each hydraulic stretcher is very high, so that the volume and weight of the entire stretching tool are very large, which brings great inconvenience to the operator in the actual use of the workshop

Abstract

An elongating tool for PC2-6 diesel engine cylinder head studs comprises a tray, a plurality of hydraulic elongators, a distribution block and a lifting ring. A plurality of through holes are formed in the tray, a plurality of supporting legs in uniform arrangement are fixedly connected to the bottom of the tray, the hydraulic elongators are movably disposed in the through holes respectively, the distribution block is fixed at the center of the tray, a hydraulic oil inlet is formed in the top of the distribution block, a plurality of hydraulic oil outlets formed on the lateral side of the distribution block are connected with the hydraulic elongators respectively, and the lifting ring is fixedly connected with the tray through a plurality of slings. The elongating tool has the advantages of simple structure, small size, flexible combination, convenience in operation, high efficiency and practicality, and can be used for mounting and demounting of cylinder head nuts in the process that a diesel engine cylinder head is mounted or demounted.

Description

technical field [0001] The invention relates to a tool for assembling a large diesel engine, in particular to a stretching tool for a cylinder head stud of a PC2-6 diesel engine, which belongs to the technical field of diesel engines. Background technique [0002] PC2-6 diesel engine is a medium-speed diesel engine for large ships, and the weight of its cylinder head and other parts is measured in tons. During the production and maintenance process of the diesel engine, the disassembly and assembly of the cylinder head is often involved. To disassemble the cylinder head, it is necessary to turn 8 cylinder head nuts on the cylinder head. The studs have a certain axial locking force, and the locking force is greater on the cylinder head studs of a large diesel engine such as PC2-6 diesel engine, which cannot be overcome by manual work, so a kind of locking force must be used in the disassembly process. The hydraulic tensioner that can be purchased in the market. When disasse...
