Title:
TAMPING DEVICE VIBRATION COMPONENT COMPRISING COOLING DEVICE, AND CORRESPONDING COOLING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/056933
Kind Code:
A1
Abstract:
A tamping device vibration component comprising a cooling device, and a cooling method therefor. The tamping device vibration component comprises an eccentric vibration shaft (1), a vibration bearing (21, 22, 23), and a vibration bearing sleeve (31, 32, 33). An inner side of the vibration bearing (21, 22, 23) is connected to the eccentric vibration shaft (1). An outer side of the vibration bearing (21, 22, 23) is connected to the vibration bearing sleeve (31, 32, 33). An outer side of the vibration bearing sleeve (31, 32, 33) is connected to a cooling device (41, 42, 43). The cooling method comprises: arranging the cooling device (41, 42, 43) on the periphery of a high temperature part of a vibration shaft component of a tamping device, injecting a coolant from a cooling inlet (422), flowing through a cooling channel (421), and flowing out from a cooling outlet (423) so as to take away the heat of the high temperature part and cool the high temperature part. By using the tamping device vibration component and the cooling method therefor, the vibration component can be effectively cooled, the high-frequency operation of the tamping device is achieved, and the service life of the tamping device is prolonged.
