Description
Technical field
The present invention relates to electric power overhaul technical field more particularly to it is a kind of for climb rhabodoid for rope to be taken
It is hung on the device of overhead line.
Background technique
On daily removing high-voltage line when foreign matter, when foreign matter is closer apart from operator, can by insulating bar come
Carry out auxiliary removing.But foreign matter is remote apart from operator, when not being available insulating bar removing, needs operator's throwing exhausted
Edge rope, when operation, it is necessary first to which operator climbs up power transmission tower, selects appropriate location, position here will be according to transmission line of electricity
Voltage class is determined, and 110KV is 1.5 meters, and 220KV is 3 meters, and 330KV is 4 meters, 500KV is 5 meters, and many positions are also connected with
Weight is bound in insulating cord one end by insulator chain, and conducting wire one end of foreign matter is hung in throwing, and underground job personnel are by insulating cord two
It holds while being moved to foreign matter position, " crescent moon fork " tool is tied up on insulating cord, and by pullling insulating cord, be transferred to foreign matter
Position constantly pulls insulating cord by underground activities personnel, utilizes " crescent moon fork " wound foreign matter, finally by it from conducting wire supernatant
It removes.
But because being fitted with stockbridge damper close to power transmission tower side, the staff of throwing rope is difficult once will just restrict
Rope send the position to other than stockbridge damper, and rope is often blocked by stockbridge damper, it is also necessary to try every possible means first to remove rope, operate in this way
Method extend the working time, increase the working strength of operator, and because operating position belongs to high altitude operation, throw
Human body amplitude of fluctuation is very big when throwing insulating cord, has seriously affected the personal safety of operating personnel.It can be with when being closer
Rope is sent to designated position by more insulating bars of connection, but when apart from farther out, insulating bar connection is very long, will restrict
The weight connected on rope and rope is mounted on the insulating bar other end, requires the arm strength of operator very high.

Specific embodiment
Technical solution in order to enable those skilled in the art to better understand the present invention with reference to the accompanying drawing and is embodied
Mode elaborates to the present invention.
As shown in Figures 1 to 8, the invention discloses it is a kind of for by rope lodge in the device of overhead line, the device packet
Include bracket 10, telescoping mechanism 20, rocker arm 30 and clamping device 40.Bracket 10 is removable installed in the cross-arm 100 of pylon
On, the cross-arm 100 of pylon is vertical with the trend of overhead line 200 (it is vertical to can be antarafacial).Telescoping mechanism 20 is horizontally placed on bracket 10
It can rotate above and on perpendicular to the plane on its extending direction, extending direction and the overhead line 200 of the telescoping mechanism 20
Trend is parallel.Rocker arm 30 is connected to the distal end (one end far from bracket 10) of telescoping mechanism 20, by telescoping mechanism 20
It rotates and waves.Clamping device 40 is connected to the free end of rocker arm 30, and clamping device 40, which has, keeps rope 400 thereon
Clamp position and the opening state for discharging rope 400.When telescoping mechanism 20 is by flexible, and rocker arm 30 by swing and
When driving clamping device 40 from the top of overhead line 200 across overhead line 200, by cutting clamping device 40 from clamp position
Opening state is shifted to, and rope 400 is discharged so that 400 lodge of rope is on overhead line 200.
The application method of a line above-mentioned apparatus is described below:
As shown in fig. 7, whole device is installed on the cross-arm 100 of pylon by bracket 10 first, at this point, telescoping mechanism
20 is parallel with overhead line 200 and apart from 200 a distance of overhead line；So that clamping device 40 is switched to opening state, makes rope
400 are set in clamping device 40 and so that clamping device 40 is switched to closed state again, at this point, rope 400 is clamped mechanism
40 are kept；Then, as shown in figure 8, the length of obstacle can be avoided after swinging the elongation of telescoping mechanism 20 to rocker arm 30
(the application is only illustrated for avoiding stockbridge damper 300)；Then, as shown in figure 8, force is so that 20 turns of telescoping mechanism
It is dynamic, so that rocker arm 30 rotates, when the rotational angle of rocker arm 30 makes rope 400 clamped by clamping device 40 across frame
When ceases to be busy 200, control clamping device 40 switches to opening state, at this point, rope 400 falls with lodge on overhead line 200.
The present invention using the Telescopic of telescoping mechanism 20 and the swing function of rocker arm 30 avoids obstacle and by rope
400 across overhead line 200, and makes 400 lodge of rope on overhead line 200 by the opening of clamping device 40, and then avoid
Using a series of problems mentioned in background technique brought by worker's throwing rope 400.
