Embodiment 1
[0043] A snow clearing device for power transmission cables includes a running mechanism and a snow removal mechanism. The running mechanism includes an active running mechanism and a plurality of auxiliary running mechanisms. In this embodiment, the auxiliary running mechanism is arranged below the active running mechanism.
[0044] The active traveling mechanism includes a track 1, a support plate 2, a transmission shaft 3, a gear 4, a rack 5 and a traveling driving mechanism. The track is a cavity structure, specifically: such as figure 1 and figure 2 As shown, the track 1 includes a track upper plate 101, a track lower plate 102 and two track side plates 103. The track upper plate 101, the track lower plate 102 and the two track side plates 103 surround and form a cylindrical structure with a rectangular cross section. The lower surface of the upper plate 101 is provided with a dovetail groove 104, the dovetail groove 104 is a long groove, the length direction of the dov...
Embodiment 2
[0055] This embodiment 2 is the same as embodiment 1, the difference is that a kind of power transmission cable snow removal device in this embodiment 2 also includes an ice crushing mechanism, such as Figure 7 As shown, the ice crushing mechanism includes two first half cylinders 26 , a second half cylinder 27 , a semi-circular cutter 29 , a swivel 25 , an ice crushing gear 24 , and an ice crushing motor 23 surrounding a cylindrical structure.
[0056]The ice crushing motor 23 is located on the upper surface of the support box upper plate 1001, the chassis of the ice crushing motor 23 and the support box upper plate 1001 are fixed by bolts, the ice crushing gear 24 is connected with the output shaft key of the ice crushing motor 23, and the swivel 25 is set On the back plate 1005 of the support box, the swivel 25 is connected to the back plate 1005 of the support box through bearings, the ice crushing gear 24 meshes with the outer ring of the swivel ring 25, and the first hal...
Embodiment 3
[0060] Embodiment 3 is the same as Embodiment 2, the difference is that a power transmission cable snow removal device in Embodiment 3 also includes an ice scraping mechanism, such as Figure 8 As shown, the ice scraping mechanism is arranged on the side of the ice crushing mechanism away from the auxiliary walking mechanism, and the ice scraping mechanism includes two third half cylinders 30 that surround and form a cylindrical structure, and a support box between the third half cylinders 30 and the support box. The ice scraping connecting rod 31 is connected with the two third half cylinders 30 by fasteners, the axis of the third half cylinder 30 coincides with the axis of the power transmission cable, the fasteners are specifically bolts, and one end of the ice scraping connecting rod 31 is connected to the first half cylinder. The three half cylinders 30 are hinged, and the other end of the ice scraping connecting rod 31 is hinged with the support box rear plate 1005 .
