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 piston of 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. The piston ring between the rear end of the cylinder and the piston in the conventional breaking hammer has low supporting force on the piston, so that the service life of the piston is influenced, and the use of the breaking hammer is further 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 increasing the service life of a piston of a demolition hammer to increase the supporting force of the piston ring on the piston.
The purpose of the utility model can be realized by the following technical scheme: the improved structure is characterized in that the improved structure is arranged between the piston ring and the piston, the improved structure comprises a plurality of guide rings, and each guide ring is made of composite materials.
In the above improved structure for prolonging the service life of the piston of the breaking hammer, the piston ring is provided with a plurality of mounting grooves for mounting corresponding guide rings.
In the above improved structure for prolonging the service life of the piston of 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 improvement quartering hammer piston life, 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 piston of the breaking hammer, the guide ring is made of an organic material or a high polymer material.
In the above improved structure for prolonging the service life of the piston of the breaking hammer, the guide ring is of a whole ring-shaped structure.
In the above improved structure for prolonging the service life of the piston of 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 piston of the breaking hammer, the upper inclined plane and the lower parallel plane form 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: through set up a plurality of guide rings between piston ring and piston, have the increase piston ring and to piston holding power, and then improve piston and quartering hammer life's advantage.

Preferably, the piston ring 3 is provided with a plurality of mounting grooves 5 for mounting the corresponding guide rings 4.
Preferably, the number of the plurality of guide rings 4 is 1 to 3, and the number of the corresponding mounting grooves 5 is also 1 to 3.
Preferably, chamfers 6 are arranged on the outer edge and the inner edge of the guide ring 4.
Preferably, the guide ring 4 may also be made of an organic material or a polymer material.
The first embodiment is as follows:
the guide ring 4 is of a whole ring-shaped structure, and the guide ring 4 of the whole ring-shaped structure has the advantage of strong integrity.
Example two:
a notch groove 7 is formed in the guide ring 4, the left groove face of the notch groove 7 is a plane 8, the right groove face of the notch groove 7 is composed of an upper inclined face 9 and a lower parallel face 10, and the notch groove 7 is designed to reduce cost and facilitate installation.
Preferably, the upper inclined surface 9 and the lower parallel surface 10 have an angle α therebetween.
The specific embodiments described herein are merely illustrative of the spirit of the utility model. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the utility model as defined in the appended claims.
