Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment technology, specifically to a lubrication device for mining truck leaf springs. Background Technology

[0002] Mining trucks, as essential tools for mining and transportation, rely heavily on their stability and durability for efficiency and safety in mining operations. Leaf springs, a crucial component of the mining truck suspension system, withstand various impacts and vibrations during vehicle movement; therefore, their lubrication and maintenance are of paramount importance.

[0003] However, current lubrication methods for mining truck leaf springs mostly rely on manual operation. This method is not only inefficient but also makes it difficult to ensure the uniformity and timeliness of lubrication. In the harsh working environment of mines, mining truck leaf springs are frequently corroded by impurities such as mud, sand, and water, which greatly reduces the lubrication effect and may even lead to premature wear and damage of the leaf springs, thereby affecting the driving performance and safety of the mining truck.

[0025] Please see Figure 1-4 A lubrication device for mining truck leaf springs includes two symmetrically distributed suspension system side plates 1. Leaf spring bodies 2 are installed on the outer sides of both suspension system side plates 1. Nozzles 3 are provided on the suspension system side plates 1 on opposite sides of the two leaf spring bodies 2. An L-plate 4 is installed on the outer side of one of the suspension system side plates 1. The vertical plate of the L-plate 4 is connected to the outer side of the suspension system side plate 1. A fixing plate is provided on the horizontal plate of the L-plate 4. An oil tank 5 is installed on the fixing plate. An oil outlet pipe 6 is connected to the top surface of the oil tank. The oil outlet pipe 6 is connected to multiple nozzles 3.

[0026] In this technical solution, the end of the oil outlet pipe 6 furthest from the oil tank 5 is located between the two suspension system side plates 1 and is connected to a four-way pipe. The openings on opposite sides of the four-way pipe are connected to first delivery pipes. The ends of the two first delivery pipes furthest from the four-way pipe are respectively connected to two nozzles 3. The opening on the four-way pipe opposite to the oil outlet pipe 6 is connected to a second delivery pipe. The end of the second delivery pipe furthest from the four-way pipe is connected to a three-way pipe. The two openings opposite to the three-way pipe are connected to third delivery pipes. The end of the third delivery pipe furthest from the three-way pipe is connected to the other two nozzles 3. The oil tank 5 is also equipped with a pressurizing pump for pressurizing the oil tank 5, and the outlet pipe of the pressurizing pump is connected to the pressurizing port of the oil tank 5.

[0027] Before use, fill the oil tank 5 with lubricating oil. When it is necessary to lubricate the leaf spring body 2, start the pressure pump. The output pressure of the pressure pump can be adjusted as needed, so that the lubricating oil in the oil tank 5 is discharged from the oil outlet pipe 6. The lubricating oil is sprayed out from multiple nozzles 3 at the same time through the first delivery pipe, the second delivery pipe and the third delivery pipe. The sprayed lubricating oil lubricates the leaf spring body 2.

[0028] This technical solution controls the pressurization pump to make the lubricating oil in the oil tank 5 flow out from the oil outlet pipe 6, and then pass through the first delivery pipe, the second delivery pipe and the third delivery pipe in sequence to spray the lubricating oil from multiple nozzles 3 at the same time, thereby achieving lubrication of the leaf spring body 2. Compared with manual lubrication, it not only improves work efficiency, but also improves the uniformity and timeliness of lubrication of the leaf spring body 2.

[0029] In this embodiment: the oil tank 5 is provided with an oil inlet 7 and a connecting pipe 8. The oil inlet 7 is provided with a valve. One end of the connecting pipe 8 is connected to the inside of the oil tank 5, and the other end is connected to the oil outlet pipe 6.

[0030] Lubricating oil is injected into the oil tank 5 through the oil inlet 7, and then the oil inlet 7 is closed through the valve to improve the sealing of the oil tank 5. Then, the oil tank 5 is pressurized by the pressure pump, so that the lubricating oil flows out from the connecting pipe 8 and flows through the oil outlet pipe 6, the first delivery pipe, the second delivery pipe and the third delivery pipe.

[0031] In this embodiment: each of the two suspension system side plates 1 is provided with a connecting frame 9 on its opposite side, and each of the two connecting frames 9 is provided with a connecting hole 10. A lifting lug 11 is connected between the two connecting frames 9. The two ends of the lifting lug 11 pass through the connecting holes 10 on the two connecting frames 9 respectively. A fixing seat 12 is installed at both ends of the lifting lug 11 that pass through the connecting holes 10. A clamping member 13 for clamping and fixing the leaf spring body 2 is connected to the fixing seat 12.

[0032] The leaf spring body 2 is clamped and fixed by the clamping component 13. When the mining truck operates on the harsh road surface in the mining area, the pressure of the cargo box on the vehicle is very high. As an important component on the axle of the mining truck, the leaf spring can absorb and mitigate the vibration and impact transmitted from the road surface through its elastic deformation. This buffering effect can protect the vehicle body parts from vibration damage and extend the service life of the vehicle.

[0033] Meanwhile, the lifting lug 11 makes the working state of the leaf spring body 2 more stable. In heavy vehicles such as mining trucks, the leaf spring body 2 needs to withstand huge loads and vibrations. The lifting lug 11 can effectively reduce the deformation and fatigue caused by external forces, thereby ensuring the stability and reliability of the leaf spring body 2 during long-term use.

[0034] In this embodiment, the clamping member 13 includes a fixing block 14 and multiple fixing rods 15. One end of the fixing block 14 is connected to the side plate 1 of the suspension system, and the other end extends outward. The multiple fixing rods 15 are symmetrically distributed on opposite sides of the leaf spring body 2, and both ends are detachably connected to the fixing seat 12 and the fixing block 14, respectively.

[0035] As an important component of the vehicle suspension system, the leaf spring body 2 needs to withstand enormous pressure from the vehicle body and the road surface. By fixing the leaf spring body 2 with the cooperation of the fixing seat 12, the fixing block 14 and the fixing rod 15, it can be more firmly connected to the side plate 1 of the suspension system, thereby enhancing the load-bearing capacity of the leaf spring body 2. This helps to ensure that the mining truck can maintain stability and safety under heavy loads or harsh road conditions.

[0036] In this embodiment: Four-axis clamps 16 are installed on both sides of the bottom of the two connecting frames 9, and the four-axis clamps 16 are used to clamp the wheel hub.

[0037] Tires are mounted on the wheel hub. When the mining truck operates on the harsh road surface of the mining area, vibrations are generated. These vibrations are then transmitted to the connecting frame 9 via the wheel hub and the four-axis clamp 16. The connecting frame 9 further disperses these vibrations and transmits them to the leaf spring body 2. The leaf spring body 2, as an elastic element, can absorb and mitigate these vibration energy transmitted from the road surface, thus achieving a significant shock absorption effect.

[0038] In this embodiment, the four-axis clamp 16 includes a clamping arm 161, an upper clamping block 162 and a lower clamping block 163. One end of the clamping arm 161 is connected to one side of the bottom end of the connecting frame 9. The lower clamping block 163 is installed at the other end of the clamping arm 161, and the upper clamping block 162 is installed on one side of the bottom end of the leaf spring body 2.

[0039] The two wheel hubs are connected by axles, and then the two axles are placed between the upper clamping block 162 and the lower clamping block 163. The vibration generated by the mining truck during driving is transmitted to the leaf spring body 2 for relief, thereby improving the comfort of the mining truck during driving.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
