Description

Technical Field

[0001] This utility model relates to the technical field of mining dump trucks, and in particular to a protective device for the lower kingpin lubrication point and a steering axle. Background Technology

[0002] The centralized lubrication system for mining dump trucks is an automated lubrication device designed to improve vehicle lubrication efficiency and reliability, ensuring normal operation under harsh conditions and extending the service life of components. Currently, the kingpin lubrication point in the centralized lubrication system of mining dump trucks is located at the bottom of the axle without protective devices. Dust, slag, mud, and other impurities can easily enter the lubrication point, contaminating the lubricating medium, leading to lubrication failure, and even potentially causing the lubrication point joints to detach. During vehicle operation, exposed lubrication points and pipelines are easily damaged by sharp objects, while also increasing the safety risks of personnel coming into contact with high-temperature or high-pressure lubricating media. Utility Model Content

[0003] This application provides a protective device for the lower kingpin lubrication point, a steering axle, and a mining dump truck to solve the problem that the lower kingpin lubrication point of the centralized lubrication system of the mining dump truck lacks a protective device and is exposed at the bottom of the vehicle. It can effectively prevent foreign object impact and prevent mud from covering the lubrication point.

[0004] The first aspect of this application provides a protective device for the lower kingpin lubrication point of a mining dump truck, comprising: The sleeve covers the lower kingpin lubrication point on its inner side. The sleeve is located on the inner side of the area formed by the steering axle fixing bolts. The sleeve is provided with a notch, and the lubrication line passes through the notch and connects to the lower kingpin lubrication point. A connecting plate, at least one of which is connected to the outer periphery of the sheath, and the connecting plate has a connecting hole; A connector that passes through the connecting hole to connect the connecting plate to the steering axle.

[0005] The beneficial effects of the above embodiments are as follows: The protective device has the characteristics of compact structure and small size, and has almost no impact on the original structure of the steering axle. By wrapping the lower kingpin lubrication point with a protective sleeve, it can significantly reduce the potential risks of the vehicle running under complex conditions. The device can prevent the lubrication point from being damaged by sharp objects on the road surface during driving, or prevent mud and other debris from covering the lubrication point and causing it to fall off, thereby ensuring the reliability and durability of the centralized lubrication system.

[0006] Based on the above embodiments, the embodiments of this application can be further improved as follows: In one embodiment of this application, the notch faces the steering axle. The beneficial effect of this step is that aligning the notch towards the steering axle optimizes the design of the lubrication pipeline routing, making the pipeline connection smoother and more rational. This not only facilitates installation and maintenance but also reduces the risk of wear or leakage caused by excessive pipeline bends.

[0007] In one embodiment of this application, the connecting plate is welded to one end of the sheath. The beneficial effect of this step is that it forms a strong, integrated welded assembly of the protective device, effectively improving the overall structural strength and stability, and providing better resistance to the harsh environment of the mining area.

[0008] In one embodiment of this application, the connecting member is the steering axle bolt. The advantages of this step are: directly utilizing existing bolts on the steering axle for fixing avoids adding new connecting structures to the steering axle, simplifying the overall structure, making the installation process quick and convenient, reducing maintenance and time costs, and improving the versatility of components and the efficiency of on-site replacement. A second aspect of this application provides a steering axle including the aforementioned protective device.

[0009] A third aspect of this application provides a mining dump truck, including the aforementioned steering axle. Attached Figure Description

[0013] In this application, unless otherwise expressly specified and limited, the terminology used should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral part; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of different terms in this utility model according to the specific circumstances, and the scope of the specific meaning should be limited to achieving the function of this application.

[0014] In the description of this application, it should be understood that the directional terms or positional relationships described are based on the orientation or positional relationships shown in the accompanying drawings, or based on the orientation or positional relationships in actual use, and are only for the purpose of facilitating the description of the contents of this application and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0015] Example 1 like Figure 1 , 2 As shown, a protective device for the lower kingpin lubrication point of a mining dump truck includes: a sleeve 1 covering the lower kingpin lubrication point on the inner side, the sleeve 1 being located on the inner side of the area formed by the bolts used to fix the steering axle, the sleeve 1 being provided with a lubrication pipe passing through the notch 101 and connecting to the lower kingpin lubrication point; at least one connecting plate 2 being connected to the outer periphery of the sleeve 1, the connecting plate 2 having a connecting member 3 passing through the connecting hole 201 to connect the connecting plate 2 to the steering axle.

[0016] Specifically, such as Figure 1 , 2 As shown, the sheath 1 is an overall annular sleeve structure. The sheath 1 is a steel plate with a wall thickness of 4mm. A notch 101 is opened at the edge of the sheath 1, and the notch 101 faces the steering axle.
