TECHNICAL FIELD

[0001] The utility model belongs to engineering machinery technical field, concretely speaking, especially relate to a loader drive axle brake oil pipe protection mechanism and its loader. BACKGROUND

[0002] The loader drive axle brake oil pipe in prior art is installed on A surface, only needs to be installed on the flat dry road surface, prevents the material from falling and being damaged when the shovel loading operation, but in some tropics, especially in the case of heavy rainfall, poor road conditions, the vehicle driving process inevitably passes through the muddy road section, in this working condition, the drive axle is immersed in the mud, the bridge oil pipe is impacted by the foreign matter from the front, thereby causing damage, even causing the equipment to stop.

[0003] Therefore, the existing bridge brake oil pipe installation mode has appeared in Indonesia and other tropical regions, and the following problems have appeared in the actual use process: due to the lack of protection of the front bridge oil pipe, the tire is deep in the muddy road, the oil pipe is easy to knock against the stone or top to the mud when the bridge is close to the road surface or in contact with the road surface, thereby causing damage; not only affect the brake performance of the equipment, but also may lose brake oil, and even cause dangerous situations to occur to the driver and other operators due to the lack of brake. UTILITY MODEL CONTENTS

[0004] The utility model solves the technical problem of overcoming the prior art, and provides a loader drive axle brake oil pipe protection mechanism and its loader.

[0005] In order to achieve the above purpose, the utility model is adopted with the following technical scheme:

[0006] A loader drive axle brake oil pipe protection mechanism, comprising two brake calipers, a brake oil pipe and an oil pipe joint installed at both ends of the brake oil pipe are arranged between the two brake calipers, and the mounting port of at least one end oil pipe joint is mounted on the inner side of the brake caliper; the brake oil pipe is of a bending structure, and the outer part of the brake oil pipe is provided with an upper protection plate for preventing the brake oil pipe from being knocked.

[0007] Preferably, the upper protection plate is a bending plate, and the upper protection plate is installed on the drive axle through the mounting seat.

[0008] Preferably, the side surface of the brake caliper is provided with a front protection plate for preventing the brake oil pipe from being knocked.

[0009] Preferably, the front protection plate is a bending plate arranged upward and downward, and one end of the upper protection plate is arranged inside the front protection plate.

[0010] Preferably, the front protection plate is installed on the brake caliper through the bolt.

[0011] A loader provided with the loader drive axle brake oil pipe protection mechanism according to any one of the preceding claims.

[0012] Compared with the prior art, the loader has the advantages that:

[0013] 1. The brake oil pipe provided with the bending structure between the two brake calipers and equipped with the upper protection plate and the front protection plate can effectively prevent the brake oil pipe from being damaged due to external bumps or vibrations, thereby ensuring the reliability and safety of the brake system.

[0014] 2. The upper protection plate and the front protection plate in the form of the bending plate are adopted, so that the weight of the protection plate is reduced, and the service life is improved.

[0015] 3. The oil pipe joint at least at one end is installed on the inner side of the brake caliper, so that the installation is more compact and reasonable, and the later maintenance and inspection are facilitated.

[0016] 4. The brake oil pipe with the bending structure and the matched protection plate can better adapt to the limited space layout inside the loader, so that the arrangement of the components is more scientific and reasonable, and the space utilization is improved.

[0017] 5. The application of the protection mechanism not only enhances the stability and reliability of the brake system of the loader, but also indirectly improves the overall working efficiency and operating performance of the loader due to the reduced failure rate.

[0018] 6. The protection mechanism can achieve better protection effect than the prior art without adding a new structure (a new protection plate or increasing the area of the protection plate), and only needs to change the position of the oil pipe joint, so that the modification is simple and reliable.

[0019] In summary, the protection mechanism can protect the drive axle brake oil pipe, avoid damage to the brake system due to bumps, ensure the durability of the equipment in harsh road conditions, improve the operation safety of the loader, and can be modified on the original equipment, improve the reliability of the equipment and simplify the improvement difficulty, and is more safe, durable, easy to maintain and has high space utilization, which is of great significance to improve the operation efficiency of the loader and protect the safety of the operator.

[0025] The utility model will be further described below by specific embodiment and in conjunction with the drawings.

[0026] Embodiment 1:

[0027] As Figures 1-3 shown, a loader drive axle brake oil pipe protection mechanism, including two brake calipers 3, two brake calipers 3 between the brake oil pipe 4 and the oil pipe joint 2 installed at both ends of brake oil pipe 4 are provided, and the installation port of at least vulnerable to damage one end oil pipe joint 2 is installed in brake caliper inner side 1; brake oil pipe 4 is the bending structure, and the outside of brake oil pipe 4 is provided with the upper protective plate 5 for preventing brake oil pipe 4 from knocking, and the upper protective plate 5 is the bending plate, and the upper protective plate 5 is installed on drive axle 8 through mounting seat 7.

[0028] The installation port of brake oil pipe 4 is changed from A face to brake caliper inner side 1 in this embodiment, avoids the oil pipe joint 2 of bridge oil pipe or brake oil pipe 4 from being impacted from the front, so as to realize the protection effect, and the protection is carried out through upper protective plate 5, further ensure the durability of equipment under the bad road condition.

[0029] Embodiment 2:

[0030] As Figure 4As shown, different from the embodiment 1, the side of the brake caliper 3 is provided with a front guard plate 6 for preventing the brake oil pipe 4 from being bumped, the front guard plate 6 is a bending plate arranged in up and down, and one end of the upper guard plate 5 is arranged inside the front guard plate 6, and the front guard plate 6 is mounted on the brake caliper 3 through bolts. By arranging the bending structure brake oil pipe 4 between the two brake calipers 3, and providing the brake oil pipe 4 with the upper guard plate 5 and the front guard plate 6, the damage of the brake oil pipe 4 caused by external bumping or vibration can be effectively prevented, so as to ensure the reliability and safety of the brake system; at the same time, considering the complex factors in the working environment, such as uneven ground, obstacles, muddy road conditions and the like, which may cause damage to the brake oil pipe 4, the upper guard plate 5 and the front guard plate 6 in the form of bending plate are adopted in the utility model, which not only reduces the weight of the guard plate, but also improves the service life under the condition of not reducing the protection strength and achieving the same protection effect, therefore, through the double protection of the upper guard plate 5 and the front guard plate 6, more comprehensive protection of the drive axle brake oil pipe is further realized.
