Embodiment Construction
[0017] The present invention relates to a hydraulic oil tank cooling device for roadheaders. The specific structure of the present invention will be described below:
[0018] The cooling device for the hydraulic oil tank of the roadheader includes a temperature sensor 2 arranged on the hydraulic oil tank 1 and a nozzle 3 that sprays water mist toward the hydraulic oil tank 1. The nozzle 3 is arranged at the end of the pressurized water pipe 8, and a solenoid valve is arranged on the water pipe 8 near the nozzle 3 4. The control lines of the solenoid valve 4 and the temperature sensor 2 are connected to the temperature controller 5 .
[0019] The inlet and outlet of the electromagnetic valve 4 are connected to the water pipe 8 through a quick connector, which is convenient for pipeline connection and replacement of the water pipe, and the water inlet end of the water pipe 8 is connected to the cooling circulation water circuit. The support 9 erects the nozzle 3 above the hydrau...

The invention relates to a heading machine hydraulic oil tank cooling device, and belongs to auxiliary equipment of heading equipment. According to the adopted technical scheme, the heading machine hydraulic oil tank cooling device is characterized in that a temperature sensor arranged on a hydraulic oil tank and a sprayer are included, the sprayer sprays water mist to the hydraulic oil tank and is arranged at the end portion of a pressured water pipe, the position, close to the sprayer, of the water pipe is provided with an electromagnetic valve, and a control wire of the electromagnetic valve and the temperature sensor is connected to a temperature controller. The heading machine hydraulic oil tank cooling device has the advantages that the device can solve the problem about cooling of an existing heading machine hydraulic oil tank, and the improvement cost is low; the temperature controller is adopted in the device, the cooling spraying time is determined, the work efficiency is high, and compared with manpower operation, manpower is saved; and the device is good in environment adaptability, the device can be used in the heading operation face with the complex environment, and the fault rate is low.
Description
technical field [0001] The invention relates to a cooling device for a hydraulic oil tank of a roadheader, which belongs to the auxiliary equipment of the roadheader. Background technique [0002] At present, the cooling device of the oil tank of the tunneling machine in the comprehensive excavation working face of the coal mine generally adopts water cooling, but the cooling water can only be manually turned on before starting the machine, and the built-in temperature sensor can only sense the temperature change, and the oil temperature can be fed back to the oil temperature gauge, and cannot be realized automatically. The cooling water is turned on, and it is easy to be damaged, so that when the roadheader is running, the temperature of the oil tank rises rapidly, causing oil quality variation, resulting in damage to hydraulic system components, and seriously affecting the normal operation of the roadheader. Contents of the invention [0003] The invention provides a coo...
