It has solved the problem that cylinder and piston life are low in the current quartering hammer. This improve structure that improves jar and piston life in quartering hammer, this quartering hammer have included well cylinder body and set up the piston in well cylinder body, should improve the structure and set up between well cylinder body and piston, improve the structure and include a plurality of guide ring, and each guide ring is made by organic material. The utility model has the advantages of avoiding rigid contact between the middle cylinder and the piston and prolonging the service life of the middle cylinder and the piston.
Description
Technical Field
The utility model belongs to the technical field of breaking hammers, relates to a breaking hammer, and particularly relates to an improved structure for prolonging the service life of a cylinder and a piston in the breaking hammer.
Background
With the rapid development of construction machines, the market demand for hydraulic breakers as the working parts of hydraulic excavators has also rapidly increased, because the breakers have a large impact force and are widely used for mountain rock breaking, road cutting, and the like. At present, rigid contact of iron to iron is adopted between a cylinder and a piston in the breaking hammer, and under the action of a long time, the service lives of the cylinder and the piston are shortened, so that the use of the breaking hammer is influenced.
Disclosure of Invention
The present invention is directed to solving the above-mentioned problems of the prior art by providing an improved structure for improving the service life of a cylinder and a piston in a demolition hammer to avoid rigid contact between the cylinder and the piston.
The purpose of the utility model can be realized by the following technical scheme: the improved structure is arranged between the middle cylinder body and the piston, and comprises a plurality of guide rings, and each guide ring is made of organic materials.
In the above improved structure for prolonging the service life of the middle cylinder and the piston of the breaking hammer, the middle cylinder body is provided with a plurality of mounting grooves for the sealing installation of the corresponding guide rings.
In the above improved structure for prolonging the service life of the cylinder and the piston in the breaking hammer, the number of the guide rings is 1 to 3, and the number of the corresponding mounting grooves is 1 to 3.
In the above-mentioned improvement structure of cylinder and piston life in the quartering hammer, the outer fringe limit and the inner fringe limit of guide ring all seted up the chamfer.
In the above improved structure for prolonging the service life of the cylinder and the piston in the breaking hammer, the guide ring is made of high polymer material or composite material.
In the above improved structure for prolonging the service life of the cylinder and the piston in the breaking hammer, the guide ring is of a whole ring structure.
In the above improved structure for prolonging the service life of the cylinder and the piston in the breaking hammer, the guide ring is provided with a notch groove, the left groove surface of the notch groove is a plane, and the right groove surface of the notch groove consists of an upper inclined surface and a lower parallel surface.
In the above improved structure for prolonging the service life of the cylinder and the piston in the breaking hammer, the upper inclined plane and the lower parallel plane have an included angle alpha.
Compared with the prior art, this improve beneficial effect that cylinder and piston life's improvement structure reached in the quartering hammer: a plurality of guide rings are added between the middle cylinder body and the piston, so that rigid contact of iron to iron between the middle cylinder body and the piston is avoided, and the service lives of the middle cylinder body and the piston are further prolonged.
