Description
Technical Field
The invention relates to hoisting equipment, in particular to a hoisting tool and method for a cylinder sleeve of a diesel engine, and belongs to the technical field of diesel engine manufacturing.
Background
The cylinder sleeve is an important part of a marine diesel engine, the weight of the cylinder sleeve is different from several tons to dozens of tons, and the cylinder sleeve needs to be lifted and matched during installation. The existing cylinder sleeve hoisting tool is heavy, inconvenient to install and has potential safety hazards.
Disclosure of Invention
The invention aims to overcome the defects of the prior art and provide a lifting tool and a lifting method for a diesel engine cylinder sleeve, which improve the lifting mode of the cylinder sleeve, improve the lifting efficiency, ensure the lifting safety and enable a single operator to conveniently lift the cylinder sleeve.
The technical scheme for solving the technical problems of the invention is as follows:
the utility model provides a lifting device for diesel engine cylinder liner, through the bolt mounting in on the cylinder liner which characterized in that: the lifting tool is a step-shaped circular flange and comprises a boss and a circular ring mounting surface, a through central threaded hole is formed in the center of the boss and used for connecting a universal lifting ring for lifting, the circular ring mounting surface is tightly attached to the end face of the cylinder sleeve, and a through hole is formed in the circular ring mounting surface and used for penetrating through the bolt and connecting and mounting the cylinder sleeve.
Furthermore, a threaded hole is formed in the circular ring mounting surface and used for connecting and placing the bolt.
Furthermore, the through holes and the threaded holes are the same in number and are evenly distributed at intervals.
The other technical scheme of the invention is as follows:
a hoisting method for a diesel engine cylinder sleeve realized by adopting the hoisting tool comprises the following specific steps:
1) closely attaching a circular ring mounting surface of the lifting tool to the end surface of the cylinder sleeve, aligning the through hole with a connecting hole on the cylinder sleeve, and mounting and screwing the bolt in the through hole and the connecting hole;
2) mounting a universal lifting ring on the threaded hole, and lifting the cylinder sleeve by using lifting equipment through the lifting tool;
3) when the universal lifting ring is disassembled, then the bolt is disassembled, the cylinder sleeve is disassembled, and the temporarily unused bolt is installed in the threaded hole to prevent loss.
Compared with the traditional technology, the invention has the beneficial effects that:
1. the lifting tool is convenient to install and use, and can be independently operated by a single operator, so that the working efficiency is improved;
2. the lifting tool is simple in structure, easy to process and manufacture and low in cost;
3. the lifting tool is high in use safety and can effectively guarantee safety.
In a word, the cylinder sleeve lifting device improves the operation quality, guarantees the safety of operators, can complete the cylinder sleeve lifting operation more conveniently and quickly, and has the advantages of high safety, convenience in operation, high working efficiency, simple structure and low cost.

Detailed Description
The present invention is further described with reference to the following drawings and specific embodiments, but the following embodiments are not intended to limit the scope of the invention, and all equivalent substitutions and modifications made according to the contents of the present specification are within the technical scope of the present invention claimed in the present application.
The invention is used for hoisting the cylinder sleeve of the diesel engine, and the cylinder sleeve is provided with connecting holes.
Referring to fig. 1 and 2, the lifting tool is mounted on the cylinder liner through bolts, and the lifting tool is a step-shaped circular flange and includes a boss 3 and a circular ring mounting surface 4. The center of the boss 3 is provided with a through center threaded hole 1 for connecting a universal lifting ring for lifting. The circular ring mounting surface 4 is tightly attached to the end surface of the cylinder sleeve, and is provided with a through hole 2 and a threaded hole 5; the through holes 2 are uniformly distributed along the circumference and are used for penetrating through the bolts to be connected and installed with the cylinder sleeve; the threaded holes 5 are used for connecting bolts which are not used temporarily to prevent the bolts from being lost, the threaded holes 5 are the same as the through holes 2 in number, are uniformly distributed along the circumference, and are distributed at intervals with the through holes 2.
The hoisting method for the diesel engine cylinder sleeve comprises the following specific steps:
1) and tightly attaching the circular ring mounting surface 4 of the hoisting tool to the end surface of the cylinder sleeve, aligning the through hole 2 with the connecting hole on the cylinder sleeve, mounting the bolt in the through hole 2 and the connecting hole, and screwing and fixing.
2) And a universal lifting ring is arranged on the central threaded hole 1, and the cylinder sleeve is lifted by using a lifting device through the lifting tool.
3) When in disassembly, the universal lifting ring is firstly disassembled, then the bolt is disassembled, the cylinder sleeve is disassembled, and the bolt which is not used temporarily is installed in the threaded hole 5 to prevent loss.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the scope of the present invention. That is, all equivalent changes and modifications made according to the contents of the present invention should be within the technical scope of the present invention.
