Description
Technical field
The utility model belongs to converting equipment cleaning applications, specifically a kind of overhead transmission line lead wire and earth wire foreign bodies removal instrument.
Background technology
Overhead transmission line construction cost is low, and short construction period is easy to repair and maintenance, therefore, and the main power transmission mode adopted since overhead transmission line transmission of electricity is electric power industry development.The mode of what the power transmission line of current most electric pressure adopted is all overhead power transmission.
But overhead transmission line lacks protection in natural environment, easily hang up the foreign matters such as plastic film, ad banner, kite.The lead wire and earth wire of overhead transmission line is in high aerial, and foreign bodies removal is more difficult.If the foreign matter on power transmission line is near high building, directly can choose with action bars, but the weight of action bars itself and length all will have influence on the operation of operating personnel, should ensure enough safe distances, again by foreign bodies removal, require higher for operating personnel, if the foreign matter on power transmission line hangs over span central authorities, when exceeding the opereating specification of action bars, operate just cumbersome, generally can only ascend a height unwheeling process or insulating cord impacts, sometimes operator is even needed to take advantage of driving to process, but this several processing mode has its limitation: operating personnel easily cause shakiness when using action bars, also enough safe distances will be ensured when live line working, because foreign matter easily swings, affect safety, action bars limited length in addition, too high circuit or adopt from the foreign matters in the lead wire and earth wire away from shaft tower is removed in this way, use insulating cord to impact the wearing and tearing of insulating cord comparatively large, potential safety hazard is caused to later live line working, 120 mm are less than at steel reinforced aluminium conductor material lead wire and earth wire upper section
2time must not hang driving, especially when circuit is charged, the leeway of selection is less.Therefore in order to remove foreign matter, eliminating safe hidden trouble, guaranteeing line security, in the urgent need to the instrument of foreign matter on a kind of charged cleaning overhead transmission line of safe ready.
Utility model content
In order to improve the coefficient of safety of overhead transmission line lead wire and earth wire foreign bodies removal, reduce the difficulty of lead wire and earth wire foreign bodies removal, the utility model provides a kind of overhead transmission line lead wire and earth wire foreign bodies removal instrument, this instrument is while guarantee job safety, improve the operating efficiency of foreign bodies removal, effective shortening activity duration, ensure line security, stablize.
For solving the problems of the technologies described above, the utility model provides a kind of overhead transmission line lead wire and earth wire foreign bodies removal instrument, comprises chopping disk, transmission device, suspension arrangement and insulating cord;
Chopping disk is circular, and have the first through hole in the middle of chopping disk, have pylon outwardly around the first through hole, pylon has slotted eye, there is cut surface at chopping disk edge;
Transmission transposition comprises U-shaped framework, horizontal bevel gear and longitudinal bevel gear, a rotating transverse axis is had between U-shaped framework two side, longitudinal bevel gear is fixed on transverse axis, guide wheel is fixed with in the middle of transverse axis, U-shaped framework diapire has the second through hole, horizontal bevel gear is arranged on pylon through the second through hole, and horizontal bevel gear and longitudinal bevel gear cooperatively interact; Insulating cord is enclosed within the groove of guide wheel, and two free ends of insulating cord pass from the first through hole;
Suspension arrangement comprises base, buckles and scroll wheel, and base is fixed on U-shaped frame roof, buckles and is fixed on base, described in buckle in hook-shaped, buckle between two side and have cross bar, scroll wheel is sleeved on cross bar.
For the purpose of describing the problem, below to overhead transmission line lead wire and earth wire foreign bodies removal instrument described in the utility model all referred to as this instrument.
During use, suspension arrangement is utilized to be suspended on overhead transmission line by this instrument, scroll wheel is relied on to roll in conductive line surfaces, reduce the friction to lead wire and earth wire, can move in lead wire and earth wire by fast and flexible, pull the free end of insulating cord, horizontal bevel gear is rotated, and then promote the rotation of longitudinal bevel gear drive chopping disk, reach the object shearing foreign matter.Operator is operated on ground, achieves safety, effectively remove foreign matter fast, reduce labour intensity, improve operating efficiency, and be applicable to various complex environment.
In order to cut foreign matter sooner, also retractable blade is fixed with on described chopping disk surface, the handle of a knife of retractable blade is fixed between pylon and cut surface, the extended chopping disk of blade, is reached the effect cut off by foreign matter when rotating by the clip between blade and chopping disk.
Buckle and be also fixed with hook, this instrument is winched to eminence by convenience aid, and is suspended on wire.
In order to meet the fail safe of live line working, the scroll wheel of this instrument, horizontal bevel gear and longitudinal bevel gear all adopt insulating material to make.
In sum, this instrument has the following advantages:
(1) safe and reliable, adopt reliable insulating material and metal material, meet live line working requirement;
(2) high-effective and labour-saving, can make personnel pass through in ground controlling, removes the various foreign matter hung in lead wire and earth wire fast;
(3) structure is simple, is easy to carry, installs and operates;
(4) practical, be suitable in complex environment and landform.
