Description

Technical Field

[0001] This utility model relates to the field of lubrication technology for road vehicle wheelsets, and in particular to a lubrication device for road vehicle wheelsets. Background Technology

[0002] The crane wheel assembly is a key component of crane equipment, mainly responsible for supporting and moving the entire crane. The crane wheel assembly refers to the device installed at the bottom of the crane for rolling on the rail. It is in direct contact with the rail, bears the entire weight of the crane, and transmits power to the rail to achieve the movement function. It consists of multiple parts that work together to ensure that the crane can operate smoothly and efficiently.

[0003] In existing technologies, some crane wheel assembly devices transmit power from the crane's power system (such as an electric motor) to the axle of the crane wheel assembly through a transmission device. The axle drives the wheel to rotate, causing the wheel to roll on the track. As the wheel rolls, the entire crane moves along the track to complete the predetermined work task. However, some crane wheel assembly devices lack a lubrication device inside, requiring workers to periodically disassemble the crane casing to add lubricating oil to the axle of the crane wheel assembly. This causes inconvenience to workers and affects work efficiency. Utility Model Content

[0040] Working principle: The drive shaft 17 is connected to the output end of the motor of the crane's power unit. The two ends of the hub 18 are connected to the crane, with the counterweight 9 facing downwards. When the crane is working, the oil pump 2 is started, drawing lubricating oil from the oil tank 15 through the return oil pipe 16 and delivering it to the hollow tube 11 through oil pipe 3 and oil pipe 10. At the same time, the power unit is started, driving the drive shaft 17 to rotate. When the drive shaft 17 rotates, it drives the turntable 12 to rotate, which in turn drives the impact rod 13 to rotate. When the impact rod 13 rotates and touches the impact block 8, it causes the impact block 8 to move. The rotating shaft 7 connected to the impact block 8 moves with the impact block 8, and the rotating shaft 7 is connected to the hollow slider 5. When the rotating shaft 7 moves, it causes the hollow slider 5 to slide within the slide plate 4, allowing the hollow slider 5 to squeeze the damper 6, causing it to deform.

[0041] When the slide plate 4 moves, the through hole in its center moves to the bottom of the oil pipe 3. The oil pump 2 draws lubricating oil and outputs it into the oil pipe 3 through the output end. Then, the lubricating oil inside the oil pipe 3 flows into the through hole, and then flows through the oil pipe 10 into the space between the hollow pipe 11 and the drive shaft 17 to lubricate the drive shaft 17. At this time, the impact rod 13 continues to rotate with the turntable 12, and the impact block 8 rotates on the rotating shaft 7. The impact rod 13 continues to press the impact block 8, causing the impact block 8 and the connected counterweight 9 to rotate until the impact rod 13 passes the impact block 8. The impacted block 8 returns to its original position under the weight of the counterweight 9. After the impacted block 8 loses the force exerted on it by the impact rod 13, the hollow slider 5 stops pressing the damper 6, and the damper 6 begins to rebound, allowing the hollow slider 5 to return to its original position. This prevents the through hole from aligning with the oil pipe 3, thus preventing the lubricating oil in the oil pipe 3 from flowing through. This results in intermittent lubrication flowing into the hollow tube 11, ensuring that the lubricating oil can lubricate the drive shaft 17 with maximum efficiency, reducing friction, and extending the lubricating oil's service life. This reduces the frequency of adding lubricating oil, thereby improving work efficiency.

[0042] When the crane starts rapidly or brakes suddenly, the entire equipment will sway laterally due to inertia, thus applying a lateral force to the wheels. At this time, the force on the single wheel 19 is transmitted to the rotating block 22 through the second slider 21. The rotating block 22 then transmits the force to the first receiving block 23, causing the first receiving block 23 to transmit the force to the second damper 26. The second damper 26 deforms to offset part of the transmitted force. At the same time, the first receiving block 23 drives the fixed sliding shell 25 to slide along the second receiving block 27 to protect the deformed second damper 26. When the fixed sliding shell 25 moves due to the transmitted force, it drives the second connecting rod 33 to move, causing the second connecting rod 33 to slide along the second sliding groove 31. One end of the second connecting rod 33 presses against the third damper 32, causing the third damper 32 to deform and offset part of the transmitted force again, ensuring that the single wheel 19 will not have a large displacement, thus achieving the effect of protecting the single wheel 19.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
