Therefore, the prior art does not disclose drilling oil holes or oil grooves on the top of the box body 1, and the oil pipes connected to the hydraulic double-wheel milling equipment are all external plastic oil pipes. Summary of the Utility Model

[0004] The utility model provides a hydraulic double-wheel milling square pile equipment, which is used to solve the technical problems that the external heating plastic oil pipes are easily damaged by friction, aged and difficult to replace.

[0034] Embodiment 1

[0035] As Figures 1 - 2 shown, this embodiment provides a hydraulic double-wheel milling square pile equipment, including: a platform connecting frame 1, a connecting structure 2, and a hydraulic driving device 3. The platform connecting frame 1 is used to fix the entire hydraulic double-wheel milling equipment (because there are multiple screw holes on the platform connecting frame 1, and the entire hydraulic double-wheel milling equipment can be fixed by connecting bolts and fixing parts through the screw holes). One end (the upper end) of the connecting structure 2 is connected to the platform connecting frame 1, and the other end (the lower end) of the connecting structure 2 is connected to the hydraulic driving device 3. The connecting structure 2 is used to connect the platform connecting frame 1 and the hydraulic driving device 3.

[0036] The connecting structure 2 is detachably arranged (connected by bolts) between the platform connecting frame 1 and the hydraulic driving device 3. The fluid, that is, hydraulic oil, flows from inside the platform connecting frame 1 through the connecting structure 2 into the hydraulic driving device 3.

[0037] A tubing 8 is provided inside the connecting structure 2. The tubing 8 connects the platform connecting frame 1 and the hydraulic driving device 3. Through the action of the tubing 8, the hydraulic oil flows from inside the platform connecting frame 1 through the connecting structure 2 into the hydraulic driving device 3.

[0038] As Figure 3 shown, a through hole 7 is opened on the platform connecting frame 1, and an oil cavity 31 is opened inside the hydraulic driving device 3. The two ends of the tubing 8 are respectively connected to the through hole 7 and the oil cavity 31.

[0039] As Figure 4 and Figure 5 shown, the two ends of the tubing 8 are respectively a first oil port 81 and a second oil port 82. The first oil port 81 is inserted into the through hole 7, and the second oil port 82 leads to the oil cavity 31.

[0040] Figure 5 As shown, the cross-sectional area at the upper end of the connecting structure 2 is larger than that at the lower end of the connecting structure 2. Here, mainly when the oil pipe 8 faces the second oil port 82 from the first oil port 81, the oil pipe 8 narrows in the lateral direction, thus forming a structure where the cross-sectional area at the upper end of the connecting structure 2 is larger than that at the lower end of the connecting structure 2. The overall structure of the connecting structure 2 is designed according to the flow direction of the platform hydraulic oil from the through hole 7 opened on the connecting frame 1 to the oil cavity 31 opened in the hydraulic driving device 3. Therefore, the connecting structure 2 is wider at the upper end and narrower at the lower end.

[0041] In addition, as Figure 5 shown, every two oil pipes 8 form a pair. Hydraulic oil enters through the first oil port 81 of one oil pipe 8, exits through the second oil port 82 of one oil pipe 8 and flows into the oil cavity 31. The hydraulic oil in the oil cavity 31 then enters through the second oil port 82 of the other oil pipe 8 and exits through the first oil port 81 of the other oil pipe 8, thus realizing the circulating flow of the hydraulic oil.

[0042] The internal structure of the hydraulic driving device 3 will not be described in detail here. The hydraulic driving device 3 is a conventional hydraulic driving mechanism. After the hydraulic oil enters through one oil pipe 8 and passes through the oil cavity 31, the hydraulic oil then exits through the other oil pipe 8, and the hydraulic driving device 3 drives the two milling wheels 4 to rotate in opposite directions.

[0043] The main improvement of the present utility model is that a plurality of oil pipes 8 are provided in the connecting structure 2. The hydraulic oil flows from the first oil port 81 of one oil pipe 8 through the second oil port 82 of this oil pipe 8 into the oil cavity 31 of the hydraulic driving device 3, and the hydraulic oil in the oil cavity 31 then flows from the second oil port 82 of the other oil pipe 8 into the first oil port 81 of this oil pipe 8.

[0044] Embodiment 2

[0045] Based on Embodiment 1, a hydraulic auxiliary part 6 is provided on the platform connecting frame 1. The hydraulic auxiliary part 6 is connected to the first oil port 81 of the oil pipe 8 through an oil extraction pipe (not shown in the figure). The hydraulic auxiliary part 6 plays a role in returning oil. Specifically, the hydraulic auxiliary part 6 can be a motor or an oil pump. When the oil pressure of the hydraulic oil in the oil cavity 31 is too high, the hydraulic auxiliary part 6 extracts the hydraulic oil in the oil cavity 31 from the first oil port 81. The hydraulic auxiliary part 6 plays an auxiliary role in returning oil, does not damage the hydraulic driving device 3, and ensures the construction efficiency.

[0046] Embodiment 3

[0047] As Figure 6 and Figure 7 shown, the left and right ends of the hydraulic driving device 3 are respectively connected to the two milling wheels 4. First flanges 32 are provided on the outer sides of the left and right sides of the hydraulic driving device 3, and second flanges 41 are respectively provided inside the two milling wheels 4. The second flanges 41 are detachably connected to the first flanges 32.

[0048] Specifically, a second flange 41 inside a milling wheel 4 is clamped between two first flanges 32 on one side of the hydraulic driving device 3, and the second flange 41 and the first flange 32 are connected by bolts. Similarly, a second flange 41 inside another milling wheel 4 is clamped between two first flanges 32 on the other side of the hydraulic driving device 3, and the second flange 41 and the first flange 32 are connected by bolts.

[0049] In addition, the platform connecting frame 1 is detachably connected with a positioning and guiding member 5. The positioning and guiding member 5 is used for positioning the platform connecting frame 1. The positioning and guiding member 5 is inserted into a positioning hole (not shown in the figure), and the positioning and guiding member 5 is positioned according to the position of the positioning hole.

[0050] As described above, it is only the specific implementation manner of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope recorded by the present utility model can easily think of changes or substitutions, which should all be covered within the protection scope of the present utility model. Therefore, the protection scope of the present utility model shall be subject to the protection scope of the claimed rights.
