For example, the second bearing 600 may be a linear bearing, so that the swing bracket 131 may axially slide relative to the guide shaft 135, and the friction between the swing bracket 131 and the guide shaft 135 is effectively reduced, so that the movement resistance of the swing bracket 131 may be reduced, so that the pressure between the ice breaking wheel 300 and the ice surface on the track surface may be adjusted by the ice breaking pressure adjusting mechanism 130.

In some embodiments of the present utility model, as shown in fig. 1-3, the swing bracket 131 includes a swing arm 132 and a mounting plate 133.

One end of the swing arm 132 is rotatably connected to the mounting bracket 110, the mounting plate 133 is connected to the other end of the swing arm 132, the other end of the telescopic driver 134 is rotatably connected to the mounting plate 133, and the guide hole is provided in the mounting plate 133. The setting like this, swing support 131 can promote the removal of icebreaking support 120 through mounting panel 133, and the area of mounting panel 133 can be great, is convenient for construct the guiding hole, and can avoid promoting the atress when icebreaking support 120 removes and take place the skew to make icebreaking pressure adjustment mechanism 130 can promote icebreaking support 120 removal more steadily and reliably, and the cleaning performance of icebreaking device 1 is better.

Wherein, pressure sensor can integrate on flexible drive 134 to reduce the dismouting step, improve production and maintenance efficiency.

For example, the ice breaking device 1 may be provided with a cleaning pressure range, when the pressure sensor detects that the acting force of the swing bracket 131 on the telescopic driver 134 is smaller than the cleaning pressure range, the pressure between the ice breaking wheel 300 and the ice surface is too small, and at this time, the telescopic driver 134 may push the ice breaking bracket 120 to move away from the mounting bracket 110, so as to increase the pressure between the ice breaking wheel 300 and the ice surface, so that the pressure fed back by the pressure sensor is located in the cleaning pressure range, and further the ice breaking cleaning effect of the ice breaking wheel 300 is better.

When the pressure sensor detects that the acting force of the swing bracket 131 on the telescopic driver 134 is greater than the cleaning pressure range, the pressure between the ice breaking wheel 300 and the ice surface is excessively high, and at this time, the telescopic driver 134 can pull the ice breaking bracket 120 to move towards the direction close to the mounting bracket 110, so as to reduce the pressure between the ice breaking wheel 300 and the ice surface, enable the pressure fed back by the pressure sensor to be located in the cleaning pressure range, avoid the excessive feedback impact force of the ice surface on the ice breaking device 1, and further enable the ice breaking cleaning effect of the ice breaking wheel 300 to be better and avoid the damage of the ice breaking device 1.

When the pressure sensor detects that the acting force of the swing bracket 131 on the telescopic driver 134 is in the cleaning pressure range, the current state of the ice breaking device 1 can be kept to work.

In this way, when the telescopic driver 134 drives the ice breaking support 120 to move, the ice breaking support 120 drives the ice breaking shaft 200 and the ice breaking wheel 300 to move along the moving direction of the ice breaking device 1, so that the ice breaking wheel 300 can be prevented from being separated from the track, and the ice breaking wheel 300 can be stably attached to the track surface, so that the cleaning effect of the ice breaking device 1 is ensured.

Moreover, the plurality of ice-breaking rotating shafts 200 are arranged at intervals along the moving direction of the ice-breaking device 1, so that the ice-breaking wheels 300 on the plurality of ice-breaking rotating shafts 200 of the same ice-breaking device 1 can clean the track surface respectively, and the plurality of ice-breaking rotating shafts 200 and the ice-breaking wheels 300 on the adjacent ice-breaking rotating shafts 200 can not generate position interference, so that the cleaning effect is better.
