Description
Technical field
The utility model relates to a kind of forced cooling devices for shield machine.
Background technique
Do not tear machine when integrally missing the stop due to shield machine open, overall weight is heavier (500T or so), and uses external pumping plant horizontal
When pushing tow shield is missed the stop, biggish self weight can generate biggish load, generate when eventually leading to hydraulic power unit, cylinder efficient a large amount of
Heat, the cooling device cooling effect on existing oil return line is not good enough, persistently keeps normal work to ensure to demonstrate,prove hydraulic oil
Temperature is needed to the cooling effect for improving cooling device.
Summary of the invention
The purpose of the utility model is to provide the pressure for shield machine of a kind of good cooling results and long-acting heat dissipation is cooling
Device.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of cooling dress of pressure for shield machine
It sets comprising fuel tank, one of end is set to oil inlet pipe and oil return pipe in the fuel tank, on the oil inlet pipe
Pump, filter, the pipe bending cylinder and valve being connected between the oil inlet pipe and oil return pipe, the forced cooling device further include
Radiating subassembly on the oil return pipe, the radiating subassembly include the heat dissipation tank and axial flow blower on oil return pipe, institute
It states heat dissipation tank to include cabinet and be set to the intracorporal cooling fin of case, the gap between adjacent cooling fin and cabinet forms sink flows
Road, the axial flow blower are installed on the cabinet.
Optimization, each cooling fin bending and/or bending extend.
Optimization, the side that the every cooling fin constitutes runner is equipped with multiple recess and convex block for turbulent flow.
Optimization, the spacing of two adjacent cooling fins remains identical.
Optimization, the cooling fin is equipped with multiple strainers for turbulent flow and filtering extended towards abutting fins.
Further, the strainer is tilted towards the flow direction of oil.
Since above-mentioned technical proposal is used, the utility model has the advantage that the utility model compared with prior art
The path that hot oil flows through heat dissipation region is improved using cooling fin, its residence time in heat dissipation region is improved, sets on a heat sink
The convex block or recess or strainer set can be further improved the time in residence time and balanced each region, that is, when improving cooling
Between, and then improve cooling effect.
