The purpose of this utility model is for the deficiencies in the prior art, and a kind of simple in structure, volume is little, easy to operate, deicing efficiency is high aerial cable deicer is provided.
The technical scheme that realizes the utility model purpose is:
A kind of aerial cable deicer, comprise direct current machine and be positioned at the cable bilateral symmetry and be located at deicing mechanism on the frame, deicing mechanism comprises interconnective the first axis mechanism, symmetrically arranged two group of second axis mechanism and two group of the 3rd axis mechanism, and the height adjustment mechanism that is connected with frame, wherein connected by three grades of reduction gearing mechanisms with identical speed reducing ratio between the deicing mechanism.
Described three grades of reduction gearing mechanisms are respectively first order belt transmission, second level gear drive, third level chain gear transmission.
Described the first axis mechanism by with the first axle of the coaxial setting of frame pan, be arranged on the driven pulley at the first axle middle part, a pair of first bevel gear that be oppositely arranged adjacent with driven pulley forms, driven pulley is connected by belt with direct current machine.
Described the second axis mechanism is arranged on the second bevel gear of the second axle one end by the second axle hinged with frame, and the drive sprocket that is positioned at the second axle middle part forms.
Described the first bevel gear and the second bevel gear mesh in opposite directions, guarantee deicing crop rotation counter motion.
Described the 3rd axis mechanism is arranged on the driven sprocket at the 3rd axle middle part by the 3rd axle that be arranged in parallel with frame, and the ice removing wheel of the other end forms, and driven sprocket is connected with drive sprocket by chain.
The even bolt cable wire of described ice removing wheel periphery, the end of each cable wire connects steel ball.
Described height adjustment mechanism forms by being arranged on the supporting seat and the studdle that support the adjustment barrel two ends, and studdle is connected with frame, and supporting seat is connected with the main frame of frame.
Operation principle of the present utility model: provide the driven pulley of power to the first axle by the direct current machine that carries decelerator, driven pulley drives the second bevel gear that meshes with the first bevel gear and moves simultaneously, simultaneously action is delivered to the drive sprocket on the second axle, be delivered on the driven sprocket of the 3rd axle by the chain that is attached thereto again, driven sprocket drives the ice removing wheel rotation, throw away under the effect of centrifugal force with the steel ball that cable wire connects, steel ball hits the icing on the cable, thereby reaches the purpose of broken deicing.
Advantage of the present utility model: simple in structure, volume is little, easy to operate, deicing efficiency is high, the icing that is fit to the plurality of specifications aerial cable is removed operation.
