Amount, or reduce the flow in cooling channel to realize, these modes still fail to thoroughly solve the purpose of cooling water outflow, and
And because coolant rate is reduced after transformation, cooling effect is relative to be weakened.
Directly provided in addition, the cooling medium of prior art is outside water, water quality is poor, easily produce corrosion and block up
Plug.It can be frozen in the case of environment temperature is relatively low when standby, and then cutting motor, cut reductor, Oil pump electrical machinery are caused to damage
Wound.
Meanwhile, traditional cooling system only monitors pressure and temperature and is monitored, and flow is not monitored, only in temperature
Machine can be powered off when degree exceedes limit value.When flow it is too small without power-off protection when, cooling effect is poor, causes device temperature mistake
It is high and damage.

The connection of cooling duct entrance, cutting motor, cut reductor, the cooling duct outlet of Oil pump electrical machinery pass through pipeline and casing
Connection；
Pipeline between the cutting motor, cut reductor, the cooling duct outlet of Oil pump electrical machinery and casing is provided with
Air cooler for cooling down coolant.
Such scheme turns into enclosed circulation cooling system, case by improving traditional open cooling system after improvement
Coolant in body is not outer arranges, it is to avoid tunnel ponding.
Further, between exit of pump and cutting motor, cut reductor, the cooling duct entrance of Oil pump electrical machinery
Pipeline is provided with pressure and temp flow sensor.Coolant progress reality to flowing to cutting motor, cut reductor, Oil pump electrical machinery
When monitor, when any one of pressure, temperature, flow can not meet use requirement, signal is reached processor by sensor, so as to control
Electric cabinet processed is cut off the electricity supply.
Further, liquid temperature liquid level sensor is installed on the casing.Temperature of the sensor to box house coolant
Degree and liquid level are monitored, and signal are reached into processor in the case that coolant temperature superelevation or liquid level are too low, and then control
Electric cabinet processed is cut off the electricity supply.
Further, between exit of pump and cutting motor, cut reductor, the cooling duct entrance of Oil pump electrical machinery
Pipeline is provided with the check valve for preventing that liquid from flowing back towards water pump direction, and liquid filter.
Further, the exit of pump is connected with overflow pipe by bifurcated, and the finder outlet is connected with casing；
The overflow pipe is provided with overflow valve and pressure gauge.
Further, the pipeline between the cooling duct outlet of cutting motor, cut reductor, Oil pump electrical machinery and casing
Provided with the check valve for preventing that liquid from flowing back towards cooling duct Way out.
It is preferred that, the coolant in the casing is water and the mixed liquor of ethylene glycol.Using water and ethylene glycol mixture, keep away
The problem of medium for exempting from low-temperature condition freezes, successfully avoid due to medium freezes and to cutting motor, cut reductor, oil pump
Motor causes damage.
Remarkable result of the present utility model is：
1. outside independent circulating cooling system, no liquid discharge system, it is to avoid the ponding of tunnel.
2. avoid internal system corrosion and the blocking caused by external water quality impact.
3. cooling medium uses water and ethylene glycol mixture, it is to avoid equipment damage caused by freezing under low-temperature condition.
4. be respectively provided with two sensors in system to be monitored system, it is to avoid coolant temperature superelevation, underfed,
Hypertonia and cause system heat generation amount big, extend service life.
