As shown in fig. 1, a driving system of a cutterhead according to an embodiment of the present application includes:
the speed reducer 11 is in driving connection with the milling wheel and comprises a gear oil cavity Q, wherein the gear oil cavity Q is provided with an oil outlet and an oil return port;
a heat sink 9 provided outside the speed reducer 11; and
the oil suction device 3 is used for sucking out the gear oil in the gear oil cavity Q from the oil outlet, and the gear oil returns to the gear oil cavity Q from the oil return port after being cooled by the heat dissipation device.
According to the driving system of the milling wheel, disclosed by the embodiment of the application, the heat dissipation device special for dissipating heat of the gear oil is arranged outside the speed reducer, so that the temperature of the gear oil inside the speed reducer is reduced. And the heat abstractor is provided to effectively prevent gear oil from continuously heating, thereby being beneficial to ensuring the service life of the speed reducer.
In some embodiments, the heat sink 9 uses mud to dissipate heat from the gear oil. The heat dissipating device of the embodiment utilizes slurry used by the milling wheel in the operation process as a heat exchanging medium to exchange heat with the gear oil to reduce the temperature of the gear oil, does not need to introduce a new heat exchanging medium, reduces the cost and is beneficial to arrangement.
In at least one embodiment, as shown in fig. 1, the heat dissipating device 9 is disposed above the speed reducer 11 so that the gear oil entering the heat dissipating device 9 exchanges heat with the slurry outside the heat dissipating device 9. The concentration of the slurry outside the heat sink 9 is smaller than that outside the speed reducer 11. Since the slurry outside the speed reducer 11 is mixed with stones and the like, the concentration of the slurry outside the speed reducer is large. And the slurry outside the speed reducer is easy to generate heat under the drive of the rotation of the milling wheel, so that the temperature of the slurry is higher. In order to optimize the heat dissipation effect on the gear oil, the heat dissipation device is arranged above the speed reducer 11, and the slurry above the speed reducer 11 has smaller concentration and lower temperature, so that the heat dissipation on the gear oil is accelerated.
In some embodiments, the drive system further comprises a control device arranged between the oil suction device 3 and the heat dissipation device 9. The control device controls whether the gear oil sucked by the oil suction device 3 returns to the gear oil cavity through the heat dissipation device 9. Specifically, when the temperature of the gear oil sucked by the oil suction device 3 is smaller than the set temperature, the control device controls the gear oil sucked by the oil suction device 3 to return to the gear oil cavity without passing through the heat dissipation device. When the temperature of the gear oil sucked by the oil suction device 3 is higher than the set temperature, the control device controls the gear oil sucked by the oil suction device 3 to return to the gear oil cavity through the heat dissipation device.
As shown in fig. 1, the control device comprises a control valve 6. The control valve 6 has an oil inlet, a first oil outlet and a second oil outlet. The oil inlet is connected with the oil suction device 3, the first oil outlet is connected with the heat dissipation device, the second oil outlet is connected with the oil return port, and the control valve 6 controls the oil inlet to be selectively communicated with one of the first oil outlet and the second oil outlet. When the temperature of the gear oil sucked out by the oil suction device 3 is smaller than the set temperature, the control valve controls the oil inlet to be communicated with the second oil outlet, that is to say, the gear oil can be controlled to return to the gear oil cavity without passing through the heat dissipation device. When the temperature of the gear oil sucked out by the oil suction device 3 is higher than the set temperature, the control valve controls the oil inlet to be communicated with the first oil outlet, that is to say, the gear oil is controlled to return to the gear oil cavity body after passing through the heat dissipation device.
Specifically, the oil inlet of the control valve 6 is connected to the oil suction device 3 through a first pipe 7. The first oil outlet of the control valve 6 is connected with the oil inlet of the heat dissipating device 9 through a third pipeline 10. The second oil outlet of the control valve 6 is connected with an oil return port through a second pipeline 8. The oil outlet of the heat radiator 9 is connected with an oil return port through a fourth pipeline 12.
As shown in fig. 1, the control device of the present embodiment further includes a controller 5 and a temperature sensor 4 for measuring the temperature of the gear oil in the gear oil chamber Q. The controller 5 controls the operation of the control valve 6 based on the temperature of the gear oil measured by the temperature sensor 4.
Specifically, the control valve 6 may be an electromagnetic directional valve. The controller 5 directly sends a signal to control the on-off of the electromagnetic directional valve. Specifically, the gear oil temperature signal detected by the temperature sensor is transmitted to the controller 5, and the controller 5 judges the gear oil temperature and controls the electromagnetic directional valve. For example, when the gear oil temperature is higher than the set temperature, the controller 5 controls the electromagnetic directional valve to operate so that the gear oil is returned to the speed reducer through the fourth pipeline 12 after being radiated by the radiator 9, which is a large cycle of the gear oil temperature adjustment. When the temperature of the gear oil is lower than the set temperature, the controller 5 controls the electromagnetic reversing valve to act so that the gear oil is directly returned into the speed reducer through the second pipeline 8, and the speed reducer is a small cycle for regulating the temperature of the gear oil. In the small cycle of the gear oil temperature adjustment, even if the gear oil does not pass through the heat dissipating device, the suction of the gear oil by the suction device and the flow in each pipeline can be cooled, so that the heat dissipating effect can be achieved.
The gear oil cavity comprises an inner gear oil cavity positioned inside the speed reducer and an outer gear oil cavity positioned outside the speed reducer. The oil suction device 3 includes an oil suction pump. The oil suction pump sucks out the gear oil in the internal gear oil cavity into the external gear oil cavity, and the temperature sensor is arranged in the external gear oil cavity.
As shown in fig. 1, the drive system of the present embodiment includes a hydraulic motor 1 and a drive unit 2 provided between the hydraulic motor 1 and a drive shaft of a speed reducer 11. The oil suction pump is drivingly connected to a drive shaft of the speed reducer 22.
In this embodiment, the oil suction pump is a screw pump for sealing gear oil of the speed reducer. The embodiment utilizes the screw pump in the speed reducer to suck out the gear oil, and simplifies the structure of the whole driving system.
The present embodiment also provides a slot milling machine, which includes a milling wheel and the driving system of the milling wheel described in the above embodiments.
The slot milling machine may be a two-wheel slot milling machine.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present application and not for limiting the same; while the application has been described in detail with reference to the preferred embodiments, those skilled in the art will appreciate that: modifications may be made to the specific embodiments of the present application or equivalents may be substituted for part of the technical features thereof; without departing from the spirit of the application, it is intended to cover the scope of the application as claimed.
