[0002] The statements herein only provide the background art related to the utility model and do not necessarily constitute the prior art.

[0003] A hybrid loader is a construction machinery with high operation efficiency, mainly used for shoveling, loading, transporting, excavating and other operations on loose piled materials, and can also be used for leveling the site and performing towing operations. For a loader, the front frame is the most severely stressed component among all structural components. It has to bear different loads from components such as the working device, the rear frame, and the front axle. In many cases, the front frame has to bear the simultaneous action of tensile, compressive, bending and torsional loads, and its stress condition is very harsh, which easily causes wear between the structures in the front frame. Therefore, timely lubrication of the front frame of the hybrid loader can reduce the occurrence of rust, wear, etc., and effectively improve the working efficiency and service life of the loader.

[0004] At present, when lubricating the front frame of a hybrid loader, since there are many parts to be lubricated on the front frame, it often requires workers to lubricate different parts to be lubricated in sequence, and the lubrication efficiency is not high, thus affecting the working efficiency of the hybrid loader.

[0025] The following combines with the attached Figures 1-4 to illustrate the specific implementation manner of this embodiment

[0026] The embodiment of the present application provides a centralized lubrication device for the front frame of a hybrid loader. Referring to Figure 1 , a centralized lubrication device for the front frame of a hybrid loader includes;

[0027] The first lubricating pipeline 1, the second lubricating pipeline 2, the third lubricating pipeline 3, the fourth lubricating pipeline 4 and the fifth lubricating pipeline 4; one ends of the first lubricating pipeline 1, the second lubricating pipeline 2, the third lubricating pipeline 3, the fourth lubricating pipeline 4 and the fifth lubricating pipeline 5 are all connected to the centralized lubricating block 6, and the other ends are communicated with the parts of the front frame to be lubricated. Among them, the other end of the first lubricating pipeline 1 is respectively communicated with the upper hinge pin 11 and the left lower boom pin 12; the other end of the second lubricating pipeline 2 is respectively communicated with the right lower boom pin 13 and the right upper boom pin 14; the other end of the third lubricating pipeline 3 is respectively communicated with the rocker pin 15 and the left upper boom pin 16; the other end of the fourth lubricating pipeline 4 is respectively communicated with the left steering pin 17 and the right steering pin 18; the fifth lubricating pipeline 5 is communicated with the center frame 19. Multiple lubricating pipelines are arranged along the frame and fixed by the threaded seat 7 and the pipe clamp 8

[0028] In addition, the first lubrication pipeline 1, the second lubrication pipeline 2, the third lubrication pipeline 3, and the fifth lubrication pipeline 5 all use steel pipes to transport lubricants for lubrication. The steel pipes have high strength and pressure resistance, ensuring the normal flow of the lubricants. The fourth lubrication pipeline 4 is for lubricating the steering pin shaft of the steering cylinder. Due to the rotation of the steering cylinder, using a steel pipe as the oil pipeline may damage the steering cylinder. Therefore, in this embodiment, the fourth lubrication pipeline 4 is first connected to the centralized lubrication block 6 through a steel pipe, and a hose 20 is used to transport the lubricant in the pipeline close to the steering cylinder. In this embodiment, the hose 20 has a double-layer structure, with the inner layer made of polyamide material and the outer layer made of polyurethane material. On the basis of ensuring the flow of the lubricant, it can also prevent the pipeline from being bent and damaged. The hose 20 and the steel pipe are connected through an end straight-through joint 21 and a fixing seat 22, further avoiding the lubrication pipeline from squeezing the steering cylinder when the steering cylinder is working.

[0029] In this embodiment, a cavity for accommodating the lubricating medium is provided inside the centralized lubrication block 6, and the cavity of the centralized lubrication block communicates with the outside through an opening. A ferrule tube joint 9 is pre-installed in the lubrication pipeline and is connected to the centralized lubrication block 6 through the ferrule tube joint 9. At the end of the lubrication pipeline, the ferrule tube joint 9 is also connected to a right-angle adjustable ferrule joint 10, and the two are sealed through thread fitting and are connected to the part to be lubricated through the right-angle adjustable ferrule joint 10. By adding lubricating oil to the centralized lubrication block 6 through an oil cup (not marked in the attached drawing), it is possible to simultaneously lubricate the upper hinge pin shaft 11, the left lower boom pin shaft 12, the right lower boom pin shaft 13, the right upper boom pin shaft 14, the rocker arm pin shaft 15, the left upper boom pin shaft 16, the left steering pin shaft 17, the right steering pin shaft 18, and the center frame 19, greatly improving the lubrication efficiency.

[0030] The working principle of the centralized lubrication device provided in this embodiment is as follows:

[0031] By connecting multiple lubrication pipelines to the centralized lubrication block, it is possible to centrally lubricate all the parts to be lubricated on the front frame of the loader, without the need to lubricate each part separately, further improving the working efficiency of the loader.

[0032] Although the specific implementation mode of the present invention is described above in conjunction with the attached drawings, it is not a limitation on the protection scope of the present invention. Those skilled in the art should understand that based on the technical solution of the present invention, various modifications or deformations that can be made by those skilled in the art without creative labor are still within the protection scope of the present invention.
