Description

Technical Field

[0001] This utility model relates to the field of excavator technology, and in particular to a hydraulic pipeline layout structure for an excavator. Background Technology

[0002] Hydraulic excavators are equipped with multiple main valves and hydraulic lines for hydraulic control. The oil lines need to be installed in the corresponding positions on the excavator using a layout structure.

[0003] According to prior art, a hydraulic cylinder pipeline layout structure for an excavator and an excavator (Announcement No.: CN119531436A) are disclosed, including two stick cylinder pipelines and two bucket cylinder pipelines. The bottom axis of the stick cylinder pipeline and the bucket cylinder pipeline located on one side of the boom are parallel to each other and the plane containing the two axes is perpendicular to the upper surface of the boom. The bottom axis of the stick cylinder pipeline and the bucket cylinder pipeline on the other side of the boom are parallel to each other and the plane containing the two axes is perpendicular to the upper surface of the boom.

[0004] In existing technologies, oil pipes are fixed and limited by a fixed body. However, the position and size of the fixed body remain unchanged. During pipeline layout, there may be bending or bridging phenomena. Consequently, the fixed body needs to be set in various shapes, which causes problems for the corresponding accessories. Therefore, it is very necessary to use the same fixed body to illustrate the pipeline installation by adjusting the position of the fixed body.

[0005] Therefore, we propose a hydraulic pipeline layout structure for excavators. Utility Model Content

[0006] The present invention mainly solves the above-mentioned technical problem of needing various different fixed bodies to adapt to the layout of pipelines, and provides a hydraulic pipeline layout structure for excavators.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a hydraulic pipeline layout structure for an excavator, comprising:

[0008] Mounting base plate, the top of which is provided with a plurality of first mounting holes and second mounting holes;

[0009] A snap-fit ​​structure is set on the top of the mounting plate for fixing the pipeline. The snap-fit ​​structure includes a fixing body, clamps and threaded holes. Two sets of clamps are fixedly installed on one side of the fixing body in pairs symmetrically distributed. Threaded holes are opened on the top, bottom and side wall of the fixing body.

[0010] A connecting component is provided in the threaded hole of the fixing body for connecting the fixing body to the second mounting hole.

[0011] In a preferred embodiment of this utility model, the first mounting holes are located at the four corners of the mounting base plate, and a plurality of second mounting holes are arranged in a row at the middle position of the mounting base plate.

[0012] In a preferred embodiment of this utility model, the fixing body is a rectangular block structure, the gripper is an arc-shaped plate, the gripper and the fixing body are integrally formed, and the end faces of the two grippers that are close to each other are fixedly provided with baffles, the baffles are provided with through holes, and a gap is left between the two baffles.

[0013] In a preferred embodiment of the present invention, the connecting assembly includes a first column, a second column, and deformation slots. The first column is detachably connected to a threaded hole, and the second column is fixedly connected to the first column. The second column is hollow inside, and several deformation slots extending into the cavity are opened on the side wall of the second column. The second column forms several deformable petal-shaped structures through the multiple deformation slots.

[0014] In a preferred embodiment of this utility model, the first column is a cylinder, the second column is a cylindrical structure, the second column is integrally formed with the first column, and the end edge of the second column is chamfered to form a slope.

[0015] In a preferred embodiment of this utility model, the cavity of the first column is circular, the deformation groove is rectangular, the deformation groove penetrates the circumferential surface of the second column, and a petal-shaped structure is formed between two adjacent deformation grooves.

[0016] In a preferred embodiment of the present invention, the connecting assembly further includes a threaded post, which is fixedly connected to the end of the first post. The end of the first post is provided with a washer sleeved on the threaded post, and the threaded post is threadedly connected to the threaded hole.

[0017] This utility model provides a hydraulic pipeline layout structure for an excavator. It has the following beneficial effects:

[0018] 1. This excavator hydraulic pipeline layout structure, by opening threaded holes on three sides of the fixed body, allows the connecting components to be installed on different wall surfaces of the fixed body as needed, enabling adjustment of the gripper position. For example, the gripper can be located on the side or top of the fixed body. Adjustments can then be made according to the direction of the oil pipe and whether it bends or crosses bridges. With the adjustable installation position of the fixed body, even if the oil pipe has bends or inclines, the installation position of the fixed body can be adjusted to accommodate the pipeline's direction, achieving a flexible layout. During installation, simply insert the pipeline into the two grippers in the same group, and install bolts and nuts in the through holes on the gripper's edge. The two grippers then clamp and fix the pipeline close to each other. The fixed body and grippers can be made of engineering plastics or rubber, ensuring the pipeline's stability while suppressing fatigue fracture caused by mechanical vibration. Changing the installation position of the same fixed body can adapt to most pipeline layouts, simplifying the accessories.

[0019] 2. This excavator hydraulic pipeline layout structure allows for adjustment of the mounting position of the fixed body by adjusting the installation position of the connecting components. For example, when the threaded post is threaded into the threaded hole at the bottom of the fixed body, inserting the first post and the second post into the corresponding second mounting hole allows for a close fit between the bottom of the fixed body and the top surface of the mounting plate. The second mounting hole includes upper and lower circular holes. The upper half of the circular hole is interference-fitted with the first post, and the lower half is interference-fitted with the second post. The diameter of the second post is slightly larger than that of the first post. When the second post passes through the upper half of the second mounting hole... After the first column enters the lower section, since the length of the second column is greater than the lower section of the second mounting hole, the bottom of the second column is contacted by the mounting base plate, causing the petal-shaped structure between the two adjacent deformation slots to deform. As a result, the second column will form an open lantern shape. The second column and the first column are locked in the second mounting hole to fix the fixed body. Adjusting the installation position of the fixed body is simple and quick, and it is convenient to disassemble and adjust. Secondly, the first column and the second column can be made of rubber material, which can suppress resonance and cause detachment, and protect the pipeline and reduce damage caused by fatigue.

[0026] A hydraulic pipeline layout structure for an excavator, such as Figure 2 As shown, it includes:

[0027] Mounting plate 10 has several first mounting holes 11 and second mounting holes 12 on its top. Bolts can be installed in the first mounting holes 11 to fasten the mounting plate 10 to the body or boom of the excavator. The second mounting holes 12 are mainly used to install snap-fit ​​structures.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, a snap-fit ​​structure is set on the top of the mounting plate 10 for fixing the pipeline. The snap-fit ​​structure includes a fixing body 20, a clamp 21, and a threaded hole 22. Two sets of clamps 21 are fixedly installed on one side of the fixing body 20, which are symmetrically distributed in pairs. Threaded holes 22 are opened on the top, bottom, and side walls of the fixing body 20. The first mounting holes 11 are opened at the four corners of the mounting plate 10. Several rows of second mounting holes 12 are opened in the middle of the mounting plate 10. The fixing body 20 is a rectangular block structure, and the clamps 21 are arc-shaped plates. The clamps 21 and the fixing body 20 are integrally formed. The end faces of the two clamps 21 that are close to each other are fixedly provided with baffles. The baffles are provided with through holes, and there is a gap between the two baffles. The fixing body 20 is a cuboid.

[0029] In this solution, by opening threaded holes 22 on three sides of the fixing body 20, the connecting components can be installed on different wall surfaces of the fixing body 20 as needed, and the position of the clamp 21 can be adjusted. For example, the clamp 21 can be located on the side of the fixing body 20 or on the top of the fixing body 20. The position can be adjusted according to the direction of the oil pipe and whether it bends or crosses a bridge. With the adjustable installation position of the fixing body 20, even if the oil pipe is bent or inclined, the installation position of the fixing body 20 can be adjusted to meet the direction of the pipeline and achieve flexible layout. During installation, the pipeline is simply inserted into the two clamps 21 in the same group. By installing bolts and nuts in the through holes of the clamp 21, the two clamps 21 move closer to each other to clamp and fix the pipeline. The fixing body 20 and the clamps 21 can be made of engineering plastics or rubber, which can suppress pipeline fatigue fracture caused by mechanical vibration while ensuring the pipeline.

[0030] like Figure 4 and Figure 5As shown, the connecting component is disposed in the threaded hole 22 of the fixing body 20 for connecting the fixing body 20 to the second mounting hole 12;

[0031] The connecting assembly includes a first column 30, a second column 31, and deformation slots 32. The first column 30 is detachably connected to the threaded hole 22, and the second column 31 is fixedly connected to the first column 30. The second column 31 is hollow inside, and several deformation slots 32 extending into the cavity are formed on the side wall of the second column 31. The second column 31 forms several deformable petal-like structures through the multiple deformation slots 32. The first column 30 is a cylinder, and the second column 31 is a cylindrical structure. The second column 31 and the first column... The first column 30 is integrally formed. The end edge of the second column 31 is chamfered to form a slope. The cavity of the first column 30 is circular. The deformation groove 32 is a rectangular groove that penetrates the circumferential surface of the second column 31. A petal-shaped structure is formed between two adjacent deformation grooves 32. The connecting assembly also includes a threaded column 33, which is fixedly connected to the end of the first column 30. The end of the first column 30 is provided with a gasket fitted on the threaded column 33. The threaded column 33 is threadedly connected to the threaded hole 22.

[0032] In this solution, the installation position of the fixing body 20 can be adjusted by adjusting the installation position of the connecting components. For example, when the threaded post 33 is threaded into the threaded hole 22 at the bottom of the fixing body 20, the first post 30 and the second post 31 are inserted into the corresponding second mounting hole 12, so that the bottom of the fixing body 20 is fitted to the top surface of the mounting plate 10. The second mounting hole 12 includes two sections of circular holes. The upper section of the circular hole is press-fitted with the first post 30, and the lower section of the circular hole is press-fitted with the second post 31. The diameter of the second post 31 is slightly larger than the diameter of the first post 30. When the second post 31 passes through the upper section of the second mounting hole 12... After entering the lower half, since the length of the second column 31 is greater than the lower half of the second mounting hole 12, the bottom of the second column 31 is contacted by the mounting base plate 10, causing the petal-shaped structure between the two adjacent deformation slots 32 to deform. As a result, the second column 31 will form an open lantern shape. The second column 31 and the first column 30 are locked in the second mounting hole 12 to fix the fixing body 20. Adjusting the installation position of the fixing body 20 is simple and quick, and it is convenient to disassemble and adjust. Secondly, the first column 30 and the second column 31 can be made of rubber material, which can suppress resonance and cause detachment on the one hand, and protect the pipeline and reduce damage caused by fatigue on the other hand.

[0033] The working principle of this utility model is as follows: When the threaded post 33 is threadedly fastened to the threaded hole 22 at the bottom of the fixing body 20, the first post 30 and the second post 31 are inserted into the corresponding second mounting hole 12. This allows the bottom of the fixing body 20 to be fitted against the top surface of the mounting plate 10. The second mounting hole 12 includes two circular holes, an upper half of which is press-fitted with the first post 30, and a lower half of which is press-fitted with the second post 31. The diameter of the second post 31 is slightly larger than the diameter of the first post 30. When the second post 31 passes through the upper half of the second mounting hole 12 and enters the lower half, because the length of the second post 31 is greater than the lower half of the second mounting hole 12, the mounting plate 10 abuts against the bottom of the second post 31, causing the petal-shaped structure between the two adjacent deformation slots 32 to deform. As a result, the second post 31 forms an open lantern shape. The first column 30 and the first mounting hole 31 are used to fix the fixed body 20. Threaded holes 22 are opened on three sides of the fixed body 20. The connecting components are installed on different wall surfaces of the fixed body 20 as needed, which can realize the position adjustment of the clamp 21. For example, the clamp 21 can be located on the side of the fixed body 20 or on the top of the fixed body 20. The position can be adjusted according to the direction of the oil pipe and whether it is bent or crossed. With the fixed body 20 with adjustable installation position, even if the oil pipe is bent or inclined, the installation position of the fixed body 20 can be adjusted to meet the direction of the pipeline to achieve flexible layout. During installation, the pipeline is simply inserted into the two clamps 21 of the same group to realize the installation and fixation of the hydraulic oil pipe. Of course, the valve body may also need to be installed on the mounting plate 10 according to the actual situation. The oil pipe is connected to the valve body. Since this is a well-known existing technology, it will not be described in detail here.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
