Description
Technical Field
The utility model belongs to the technical field of engineering machinery, and particularly relates to a shaft sleeve structure.
Background
The wet spraying machine is a mechanical device for vegetation greening or concrete spraying, and is mainly used for engineering such as highway (railway) slope greening, slope protection, mountain management, mine re-greening, desert management, garbage treatment and the like. The wet spraying machine uses the inner lining plate in the arm support structure to reduce the friction loss between the arms.
The liner plate is mounted inside the arm cylinder, also called the inner liner plate. The lining plates are used for protecting the cylinders from being directly impacted by mutual grinding and external materials, and meanwhile, gaps between the cylinders can be adjusted by using the lining plates in different forms, so that the service lives of the cylinders and the inner lining plates are prolonged, and the economic benefit of the cylinders is improved.
However, in the prior art, the insertion arms are in contact with the peripheral arms through the lining plates, the base area is small, and the lining plates are easily worn. The inner lining plate is generally fixed on the inner side of the arm through a screw, and the inner lining plate is inconvenient to replace.
Therefore, how to design a lining plate device which is convenient to replace and not easy to wear is a problem to be solved.
Disclosure of Invention
The utility model aims to provide a shaft sleeve structure which is more convenient to replace, has a larger contact area between the whole shaft sleeve structure and a boom piece, has better sealing performance, and is more durable and less prone to abrasion.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the shaft sleeve structure comprises a lining plate, wherein one end of the lining plate is provided with a mounting plate, the mounting plate is far away from the end of the lining plate and is provided with a wedge-shaped end, the lining plate, the mounting plate and the wedge-shaped end are integrally arranged, and a plurality of through holes are formed in the mounting plate.
Further, the two sides of the inner lining plate are extended with first covered side edges, the two sides of the wedge-shaped end are extended with second covered side edges, and the first covered side edges and the second covered side edges are integrally arranged with the inner lining plate and the wedge-shaped end.
Further, the cross-section of the inner liner conforms to the cross-sectional shape of the wedge-shaped end.
The shaft sleeve structure is arranged on the wet spraying machine arm support and is used between the inner arm and the outer arm of the wet spraying machine arm support.
The beneficial effects of the utility model are as follows: the shaft sleeve is replaced by adopting a fixing mode of an external screw, so that the shaft sleeve is more convenient and the maintenance efficiency is improved; meanwhile, the inner lining plate and the wedge-shaped end adopted by the shaft sleeve are provided with the first covered side edge or the second covered side edge, the contact area is enlarged, the cladding property is strong, the sealing property is better, excessive dust entering the inside of the arm support is effectively avoided, the shaft sleeve is more durable and not easy to abrade, the raw material input amount of the shaft sleeve can be reduced due to the arrangement of the wedge-shaped end, and the cost is reduced.

Detailed Description
For a further understanding of the utility model, its features and advantages, reference is now made to the following examples, which are illustrated in the accompanying drawings.
Referring to fig. 1 to 2, the following describes the structure of the shaft sleeve according to the embodiment of the present utility model in detail.
As shown in fig. 1, the shaft sleeve structure comprises a lining plate 1, wherein one end of the lining plate 1 is provided with a mounting plate 2, the end, away from the lining plate 1, of the mounting plate 2 is provided with a wedge-shaped end 3, the lining plate 1, the mounting plate 2 and the wedge-shaped end 3 are integrally arranged, and a plurality of through holes 5 are formed in the mounting plate 2.
The two sides of the inner lining plate 1 are extended with first covered side edges 4, the two sides of the wedge-shaped end 3 are extended with second covered side edges 4, and the first covered side edges 4 and the second covered side edges 4 are integrally arranged with the inner lining plate 1 and the wedge-shaped end 3.
The cross-section of the inner liner 1 corresponds to the cross-sectional shape of the wedge-shaped end 3.
The shaft sleeve structure is arranged between the inner arm and the outer arm of the wet spraying machine arm support, and is specifically arranged between the inner arm and the outer arm of the wet spraying machine arm support, as shown in fig. 2, the shaft sleeve structure is arranged at one end of one inner arm or one end of the outer arm, the shaft sleeve structure is fixed through screw nuts, after the shaft sleeve structure is fixed, the outer surface and the inner surface of the inner lining plate 1 are respectively attached to the inner side of the outer arm and the outer side of the inner arm, meanwhile, the contact mode of the wedge-shaped end 3 and the inner lining plate 1 is consistent, the wedge-shaped end 3 is positioned outside the outer arm, and simultaneously, the first covered side 4 and the second covered side 4 are combined, so that the shaft sleeve structure has a sealing effect.
Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
