Detailed Description
The invention will be further described with reference to the accompanying drawings and specific embodiments:
referring to fig. 1, 2 and 3, a central oil path block of a shield machine cutter head comprises a shell, a fluid channel, a hydraulic channel, a high-pressure plug and a positioning hole,
the top surface and the bottom surface of the shell are respectively provided with a groove, and cuboids are arranged on the left side and the right side of the shell
A shaped edge portion;
one end of the fluid channel is arranged on the back surface of the edge part, and the other end of the fluid channel is arranged on the front surface of the shell;
one end of the hydraulic channel is arranged on the back surface of the edge part, and the other end of the hydraulic channel is arranged on the front surface of the shell;
the high-pressure plug is arranged on the side surface of the edge part;
the edge part and the front face of the shell are respectively provided with a positioning hole.
Specifically, each pipeline of the central oil circuit block of the shield machine cutter head of the embodiment is highly integrated on one oil circuit block, the size is small, the processing and the installation are easy, and no leakage can be avoided when each fluid and hydraulic oil enter each working area of the cutter head through the central oil circuit block.
As an optimization of the present invention, the fluid passage is provided in plurality.
As the utility model discloses an optimize, the high pressure end cap is including first high pressure end cap and second high pressure end cap.
As an optimization of the utility model, the hydraulic pressure passageway is provided with a plurality ofly.
Various other modifications and changes may be made by those skilled in the art based on the above-described technical solutions and concepts, and all such modifications and changes are intended to fall within the scope of the claims.
