[0046] The pipeline harness fixing assembly provided by the utility model includes a boom fixing seat 100, a boom fixing seat 200, a rotating connection structure and a swivel fixing seat 400. The boom fixing seat 100 is fixedly connected to the boom 500, and the boom fixing seat 200 is fixedly connected to the boom 600. The boom 500 and the boom 600 are rotatably connected through a pin 700. A hydraulic cylinder for driving the boom 600 to rotate relative to the boom 500 is provided between the boom 500 and the boom 600. The rotating connection structure is rotatably connected to the pin 700. The swivel fixing seat 400 is fixed to the rotating connection structure.

[0047] Through this structural setting, the wire harness or pipeline is sequentially passed through and fixed to the boom fixing seat 100, the swivel fixing seat 400 and the arm fixing seat 200. When the arm 600 rotates relative to the boom 500, the arm fixing seat 200 can drive the swivel fixing seat 400 through the wire harness or pipeline to drive the rotating connection structure to rotate relative to the pin 700. In other words, during the rotation of the arm 600, the swivel fixing seat 400 can move with it, so that the wire harness or pipeline can be adaptively adjusted, which can effectively protect the pipeline harness and greatly extend the service life of the pipeline harness.

[0048] In one embodiment of the present invention, the rotating connection structure includes a fixing member 330 and a rotating member.

[0049] The fixing member 330 is used to be connected with the pin shaft 700 , and the rotating member is rotatably connected with the fixing member 330 .

[0050] In one embodiment of the present invention, the rotating member includes a rotating bearing 310 and a mounting plate 320 .

[0051] The rotary bearing 310 is connected to the pin 700 via a fixing member 330 . The mounting plate 320 is connected to the rotary bearing 310 . The rotary fixing seat 400 is connected to the mounting plate 320 .

[0052] Furthermore, in an embodiment of the present invention, the rotary bearing 310 includes a fixed inner ring 311 , a rotary outer ring 312 , a retaining frame and rolling elements.

[0053] The rolling body is connected between the fixed inner ring 311 and the rotating outer ring 312 through a retaining frame. The rotating outer ring 312 can rotate relative to the fixed inner ring 311 . The mounting plate 320 is connected to the rotating outer ring 312 .

[0054] For example, Figures 1 to 6 As shown, the rotating outer ring 312 is movably connected to the outer side of the fixed inner ring 311 through rolling elements and a retaining frame. The fixed inner ring 311 is fixedly connected to the pin 700 through a fixing member 330. For example,

[0055] The mounting plate 320 is fixedly connected to the rotating outer ring 312. For example, a mounting hole is provided on the mounting plate 320, and the mounting plate 320 is installed on the rotating outer ring 312 through the mounting hole.

The swivel fixing seat 400 is fixedly connected to the mounting plate 320. For example, the fixing member 330 is a fixing screw. The fixing screw is passed from one side of the fixed inner ring 311 to the other side of the fixed inner ring 311 and connected to the end of the pin 700. When the boom 600 rotates, the boom fixing seat 200 can drive the swivel fixing seat 400 to drive the mounting plate 320 and the rotating outer ring 312 to rotate relative to the pin 700 through the pipeline harness. That is, during the rotation of the boom 600, the mounting plate 320 and the rotating outer ring 312 can move synchronously so that the pipeline harness can be adaptively adjusted.

Thus, the rotation resistance of the rotating outer ring 312 can be reduced, and the friction between the rotating outer ring 312 and the pin 700 can be reduced.

[0057] In one embodiment of the present invention, the fixed inner ring 311 is filled with a positioning block 340. The positioning block 340 is provided with a positioning hole. The positioning hole is adapted to the fixing screw. The fixing screw passes through the positioning hole and is connected to the pin 700.

[0058] In one embodiment of the present invention, a compression gasket 350 is provided between the fixing screw and the fixing inner ring 311 .

[0059] Specifically, if Figure 4 As shown, the positioning block 340 is a cylindrical structure, and the diameter of the positioning block 340 is equal to the diameter of the fixed inner ring 311, or the diameter of the positioning block 340 is slightly smaller than the diameter of the fixed inner ring 311. A positioning hole is provided on the central axis of the positioning block 340, and the diameter of the positioning hole is adapted to the diameter of the fastening screw. During the installation process, the positioning block 340 is first placed in the fixed inner ring 311; the pressing gasket 350 is placed on the outer end surface of the fixed inner ring 311; the fastening screw is passed through the pressing gasket 350 and the positioning hole in sequence and then connected to the threaded hole at the end of the pin shaft 700. For example, the positioning block 340 can be a rubber positioning block 340, so as to provide convenience for the installation of the positioning block 340 and provide a certain buffering effect.

[0060] In one embodiment of the utility model, the boom fixing seat 100, the stick fixing seat 200 and the swivel fixing seat 400 all include a connecting portion and a fixing portion. The connecting portion is connected to the fixing portion. A pipeline harness is provided on the fixing portion. The connecting portion of the boom fixing seat 100, the connecting portion of the stick fixing seat 200 and the connecting portion of the swivel fixing seat 400 are respectively connected to the boom 500, the stick 600 and the swivel connection structure through fasteners.

[0061] The connection part is connected to the boom 500 or the stick 600 or the mounting plate 320 by fasteners. The fasteners include but are not limited to screws. A pipeline harness insertion and fixing area is provided on the fixing part, and the pipeline harness is inserted and fixed to the pipeline harness insertion and fixing area of ​​each fixing part at one time.

[0062] It should be noted here that the number of the swivel fixing seat 400, the boom fixing seat 100 and the arm fixing seat 200 can be determined according to actual needs.

[0063] The embodiment of the second aspect of the utility model provides an excavator, including a boom 500, a stick 600, a pipeline harness and the pipeline harness fixing assembly as described above. The boom 500 is rotatably connected to the stick 600 through a pin 700. The boom fixing seat 100 is connected to the boom 500. The stick fixing seat 200 is connected to the stick 600.
