Abstract
The utility model relates to a travelling foreign matter breaker used for electric overhead power transmission lines. The travelling foreign matter breaker is characterized by comprising a trolley frame, an overhung pulley rotating around a fixed axis is arranged on the upper portion of the trolley frame, a lead-in port is arranged on the trolley frame at a position on the lower lateral portion of the overhung pulley, a control plate is hinged to the top of the trolley frame, a cutter rest is fixedly connected to the lower end of the trolley frame, and a foreign matter breaking cutter which is an eagle cutter is fixedly connected to the cutter rest. When in use of the travelling foreign matter breaker, operators can carry out live-wire work by adopting ground potential, and overhung foreign matters on the electric overhead power transmission line can be broken out by the live-wire work without requiring potential on lines. Further, the travelling foreign matter breaker has the advantages of reasonable structure, simplicity in operation, safety in use, high working efficiency and fine effect of breaking foreign matters, the number of operators can be reduced, and the like.
Description
Technical field
The utility model relates to the electricity overhead power transmission line hanger and abolishes apparatus, is a kind of electricity overhead power transmission line walking foreign matter breaker.
Background technology
In recent years, hangers such as kite string, Polypropylence Sheet, canvas have constituted the serious harm to electricity overhead power transmission line, they twine or are suspended to and very easily cause the transmission line single-phase earthing on the lead, faults such as phase fault, cause circuit normally to move, seriously will cause the electric grid large area power cut accident, for example: evening on February 25th, 2009, the kite of letting the built-in plain conductor fly away in the Temple of Heaven area, Beijing because of citizen has caused electrical equipment fault, causes some areas power failures such as the Temple of Heaven.
At present the hanger of electricity overhead power transmission line is abolished two kinds of operational methods of main employing: a kind of is that the equipotential live line working is handled; Another kind is that maintainer's outlet is handled after having a power failure.Above-mentioned two kinds of operational methods of prior art need drop into more man power and material, and have deficiencies such as operation procedure complexity, activity duration are long, operating personnel's physical demands is big, security reliability difference.
Summary of the invention
The purpose of this utility model provide a kind of can be under the situation that transmission line does not have a power failure, operating personnel adopt the earth potential live operation, the live line working of need not equipotential reaching the standard grade just can realize hanging on the electricity overhead power transmission line abolishing of foreign matter, and it is rational in infrastructure, easy and simple to handle, safe in utilization, the operating efficiency height, it is effective to abolish foreign matter, saves operating personnel's electricity overhead power transmission line walking foreign matter breaker.
The purpose of this utility model is realized by following technical scheme: a kind of electricity overhead power transmission line walking foreign matter breaker, it is characterized in that: it comprises the coaster framework, be equipped with the hanging wire pulley that dead axle rotates at the coaster framework upper, below being positioned at the hanging wire pulley side on the coaster framework, be provided with introducing port, be hinged with control board in the coaster frame roof, lower end at the coaster framework is fixed with knife rest, is fixed with foreign matter in the knife rest lower end and abolishes cutter.
It is hawk formula cutter that described foreign matter is abolished cutter.
Electricity overhead power transmission line of the present utility model walking foreign matter breaker, owing to be equipped with the hanging wire pulley that dead axle rotates at the coaster framework upper, below being positioned at the hanging wire pulley side on the coaster framework, be provided with introducing port, adopt the mode of the solid weight throwing of pull rope system to throw on the overhead transmission line of setting top, this pull rope solderless wrapped connection above the hanging wire pulley by artificial traction and the introducing port that is provided with below by the hanging wire pulley side hanging wire pulley is hung on the overhead transmission line; Terrestrial operation personnel actuating pull rope makes the hanging wire pulley walk along transmission line, and foreign matter is abolished cutter the hanger that hangs on the transmission line is abolished; Since be hinged with control board in the coaster frame roof, can be by the change of the relative framework angle of control board, and realization hanging wire pulley hangs on the overhead transmission line or from overhead transmission line and takes off.
Electricity overhead power transmission line of the present utility model walking foreign matter breaker, can be under the situation that transmission line does not have a power failure, operating personnel adopt the earth potential live operation, and the live line working of need not equipotential reaching the standard grade just can realize hanging on the electricity overhead power transmission line abolishing of foreign matter, have rational in infrastructure, easy and simple to handle, safe in utilization, the operating efficiency height, it is effective to abolish foreign matter, saves advantages such as operating personnel.
Description of drawings
Fig. 1 looks schematic diagram for electricity overhead power transmission line with walking foreign matter breaker structure master.
Fig. 2 looks schematic diagram for the left side of Fig. 1.
Fig. 3 is hawk formula blade 5 structural representations among Fig. 1.
Among the figure: 1 coaster framework, 2 hanging wire pulleys, 3 dead axles, 4 bolts, 5 foreign matters are abolished cutter, 6 knife rests, 7 control boards, 8 introducing ports.
Embodiment
The utility model is described in further detail to utilize drawings and Examples below.
See figures.1.and.2, electricity overhead power transmission line of the present utility model has coaster framework 1 with walking foreign matter breaker, on the dead axle 3 of the top of coaster framework 1 setting, be equipped with the hanging wire pulley 2 of rotation, on coaster framework 1, be positioned at hanging wire pulley 2 side-lowers and be provided with introducing port 8, be hinged with control board 7 at the top of coaster framework 1, lower end at the coaster framework is fixed with knife rest 6 by bolt 4, is fixed with foreign matter in the lower end of knife rest 6 and abolishes cutter 5.For making electricity overhead power transmission line adopt two dead axles 3, two hanging wire pulley 2 structures with walking foreign matter breaker smooth running on overhead transmission line.
With reference to Fig. 3, the foreign matter of present embodiment is abolished cutter 5 and is adopted hawk formula cutter.
When using electricity overhead power transmission line of the present utility model with walking foreign matter breaker: the operating personnel adopts the mode of the solid weight throwing of pull rope system to throw on the overhead transmission line of setting top, and this pull rope solderless wrapped connection hangs on the overhead transmission line hanging wire pulley 2 by artificial traction and the introducing port 8 by the 2 side-lower settings of hanging wire pulley above hanging wire pulley 2; Ground Operation personnel actuating pull rope makes hanging wire pulley 2 along the transmission line walking, and foreign matter is abolished 5 pairs of hangers that hang on the transmission line of cutter and abolished.Actuating utilizes the change of control board 7 relative coaster framework 1 angles at the hinged control board 7 in coaster framework 1 top, and realization hanging wire pulley 2 hangs on the overhead transmission line or from overhead transmission line and takes off.
