Description

Technical Field

[0001] The utility model belongs to the technical field of vehicles, and particularly relates to a pipeline protection device at the articulated part of an articulated structure. Background Art

[0002] Special vehicles such as road sweepers, loaders, rollers, etc. mostly adopt the pin joint form to achieve good turning performance. The vehicle frame consists of two sections of front and rear frames. The front and rear frames are connected by pin joints and are controlled by oil cylinders to keep or change the relative angle between the front frame and the rear frame, so that the vehicle can run on the ground with different turning radii of curves.

[0003] In the prior art, if no protection measures are taken for the pipelines and wires running through between the front and rear frames during the steering process of the vehicle, the outer skin of the pipelines is very easy to be scratched by the steel structures on the vehicle. The long-term use will lead to the situation of pipeline damage, which will further cause the vehicle to malfunction, bringing serious potential safety hazards to the operation of the vehicle. Especially for construction machinery vehicles that mostly adopt hydraulic transmission, the transmission medium is hydraulic oil. If leakage occurs, it is very easy to cause the phenomenon of rear-end collision of the following vehicle and environmental pollution.

[0004] Generally, the pipelines at the articulated part of the articulated structure are mostly directly arranged and installed through. Wear-resistant strips are installed on the rigid structural parts around them to protect the pipelines. The wear-resistant strips and the pipelines are in a state of sliding friction. During the use of the vehicle, it is easy to cause the falling off and wear of the wear-resistant strips. If not discovered in time, it will lead to pipeline damage, hindering the operation of the vehicle and even causing the vehicle to malfunction. Summary of the Utility Model

[0005] In view of this, the utility model provides a pipeline protection device at the articulated part of an articulated structure, which can solve the problem that the pipelines at the articulated part of the vehicle are easily scratched.

[0006] The utility model is realized as follows:

[0007] The utility model provides a pipeline protection device at the articulated part of an articulated structure, which includes a front frame, a rear frame, a pipeline, a rotating shaft, a first roller seat, a second roller seat, a third roller seat and an articulated seat. The front frame is used to guide the steering of the vehicle. The rear frame is used to carry the load behind the vehicle and ensure the stability of the whole vehicle. Articulated seats are fixed on the rear side of the front frame and the front side of the rear frame. The articulated seat on the front frame and the articulated seat on the rear frame are rotationally connected through the rotating shaft. The pipelines are longitudinally arranged side by side between the front frame and the rear frame. The first roller seat, the second roller seat and the third roller seat are fixedly connected to the rear frame.

[0008] The technical effects of a pipeline protection device at the hinge of an articulated structure provided by the present utility model are as follows: The advantages of the protection device designed in this way are as follows:

[0009] Reduce wear: The rolling friction between the rollers and the pipeline significantly reduces the degree of wear. Compared with sliding friction, the friction coefficient of rolling friction is lower, which can effectively extend the service life of the pipeline.

[0010] Improve stability: The rollers can provide more stable support, reduce the displacement of the pipeline caused by friction, and ensure the safety and stability of the vehicle during operation.

[0011] Reduce the risk of failure: Since the rollers reduce the direct contact with the wear-resistant strip, the risk of the wear-resistant strip falling off and wearing can be reduced, thereby reducing the failures caused by pipeline breakage.

[0012] Easy to maintain: The roller system is usually easier to detect and maintain. When wear or damage is found, it can be replaced in time without disassembling the entire protection device.

[0013] Improve flexibility: The design of the rollers allows the pipeline to move freely when the vehicle steers or the suspension moves, reducing the distortion or stretching of the pipeline caused by fixed friction.

[0014] Improve operating efficiency: Reducing friction means that the vehicle can move more easily during driving, improving the overall operating efficiency and reducing fuel consumption.

[0015] Enhance shock resistance: The rollers can effectively buffer external shocks and reduce the possibility of the pipeline being damaged when the vehicle bumps or drives on an uneven road surface.

[0016] Optimize the design space: By setting the rollers, the position of the pipeline can be reasonably configured, optimizing the vehicle design space and reducing the risk of interference and overlap.

[0017] Reduce noise: The noise generated by rolling friction is usually lower than that of sliding friction, which can significantly reduce the noise pollution of the vehicle during driving and improve driving comfort.

[0018] Enhance safety: The effective operation of the roller system can ensure the integrity of the pipeline, reduce the risk of leakage or other safety hazards caused by pipeline breakage, and ensure the safety of the vehicle and personnel.
