Steep-slope differential self-locking ground wire flying car

Abstract

The invention discloses a steep-slope differential self-locking ground wire flying car, which comprises wheel seat frames, V-shaped groove road wheels, an upper connecting rod, a lower connecting rod,safety buckles, a differential brake, a seat linkage plate, a pedal connecting rod, a pedal rod, a telescopic seat frame, a seat and a folding seat backrest, wherein the wheel seat frames, the road wheels and the safety buckles are symmetrically distributed at two ends of the upper connecting rod and the lower connecting rod; the differential brake is arranged on the upper connecting rod; the upper end of the seat linkage plate is hinged with the middle of the lower connecting rod and the lower end is coaxially hinged with the upper end of the pedal connecting rod and a fixed end of the telescopic seat frame; the pedal rod is fixed at the lower end of the pedal connecting rod; the seat is arranged at a movable end of the telescopic seat frame; and the folding seat backrest is arranged onthe seat. According to the ground wire flying car, the speed is effectively controlled through the differential brake to form differential protection; the condition that operating personnel fly out due to the fact that a pulling rope is suddenly pulled off is avoided to ensure the personal safety of the operating personnel; and the steep-slope differential self-locking ground wire flying car conforms to the ergonomic structure to improve the work efficiency of the operating personnel.

Description

Technical field [0001] The invention relates to the technical field of electric power overhaul equipment, in particular to a self-locking ground wire speed car with a large gradient speed difference. Background technique [0002] At present, the work on the overhead ground wire of 500kV transmission lines in China generally uses the conventional 120cm*42cm and 138cm*42cm alloy aluminum flying cars, which are mainly used for the elimination of the overhead ground wire (anti-vibration hammer reset, ground wire and optical cable break Stock repair), installation of lightning protection devices, and installation of online detection devices. When using a flying car to repair broken strands on the ground, when encountering high and low gears and large slopes, due to the weight of the human body, the front and rear wheels of the existing ground flying car are easy to swing back and forth when moving, and the brake device engages with the ground. Unreliable, it is difficult to control t...
