Description

Technical Field

[0001] The utility model relates to the technical field of excavator equipment, in particular to a guide wheel which can be automatically lubricated. Background Art

[0002] An excavator is an earth-moving machine that uses a bucket to dig materials above or below the bearing surface and loads them into a transport vehicle or unloads them to a stockpile. The structure of an excavator generally includes a working device, an upper vehicle part, and an lower vehicle part. The main function of the lower vehicle part is the traveling device of the excavator, which usually includes main components such as crawler tracks, supporting wheels, supporting wheels, and guide wheels. The guide wheel is arranged on the chassis of the excavator and a tensioning device is installed on the rear side, which plays a guiding role for the chain and the like. In actual use, after the guide wheel has been running for a long time, the lubricating oil on the surface of the guide wheel will gradually dry up, resulting in a greater friction force when the guide wheel is connected to the chain, which will generate a large noise. At the same time, the surface of the guide wheel will be contaminated with more dust, dirt and other debris during driving, resulting in an increase in the friction force between the guide wheel and the chain, which is easy to cause the guide wheel and the chain to fall off or fail to operate normally, which has become one of the more common faults of the excavator. In view of this, the inventor proposes an automatically lubricated guide wheel to solve this problem, and the guide wheel is continuously lubricated by a self-lubricating device.

[0003] In order to realize automatic lubrication of the guide wheel and effectively avoid the blockage of the oil circuit by mud, a Chinese patent application, announcement number: CN218643454U, discloses an excavator guide wheel with a lubrication structure. The utility model includes a wheel body, a connecting groove is provided on one side of the wheel body, a side plate is movably connected to one side of the connecting groove, a lubrication mechanism is provided on the outer side of the wheel body, the lubrication mechanism includes a fixed plate and a fixed frame, one side of the fixed plate is fixedly connected to the fixed frame. The lubricating oil stored in the lubrication mechanism can be added when the wheel body rotates, thereby reducing the friction between the side plate and the wheel body and reducing the noise generated when the wheel body rotates. The cleaning wheel rotates to shake off the mud on the surface of the wheel body after it is stained with mud, so as to avoid the cleaning wheel being stained with more mud and causing obstruction to the chain.

[0004] This solution still has some shortcomings in application. Usually, the working conditions of excavators are more complicated, and the walking device is usually impacted by mud or hard objects. Therefore, the lubrication device needs to be fixed, otherwise it is easy to fall off. At the same time, due to the complexity of the working conditions, the frequency of guide wheel lubrication is also involved. Under different working conditions, the lubrication frequency of the guide wheel is different and needs to be adjustable. Therefore, it is necessary to improve the structure of the guide wheel lubrication device so that it is not only structurally stable, but also able to adjust the lubrication frequency to improve the practicability of the guide wheel lubrication device.
