The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Fig. 1～Fig. 5, a kind of high voltage transmission line overhaul electric runaway of the utility model and conducting wire deicing robot stop mechanism, it packs driving wheel assembly 1, valve 3, brake wheel support 4, screw rod 5, mainframe 6, differential nut 7, terminal pad 8, speed controller 9, slide block 10, braking motor pilot 11, braking motor 12 and braking motor support 13.Mainframe 6 is provided with a tapped bore 601, braking motor support 13 and a speed controller 9; Tapped bore 601 is on the line of centers between drive wheel assembly 14 and track adjusting wheel assembly 15, tapped bore 601 is provided with differential nut 7, differential nut 7 belows are provided with screw rod 5, screw rod 5 belows are provided with brake sheave support 4, on brake sheave support 4, be hinged with valve 3, brake sheave support 4 is provided with brake wheel assembly 1 with valve 3 belows; Braking motor 12 belows are provided with terminal pad 8, and be connected on differential nut 7, on braking motor 12, be also provided with slide block 10, braking motor support 13 inner sides, both sides are provided with chute 131, slide block 10 can slide up and down in chute 131, between braking motor 12 and speed controller 9, is provided with braking motor pilot 11.
On differential nut 7 cylindricals, be processed with the screw thread, the endoporus that match with tapped bore 601 on mainframe 6 and be processed with the screw thread matching with screw rod 5, internal and external threads rotation direction is identical, outside thread pitch L
