Description
Technical field
The present invention relates to electrical network construction and maintenance special equipment field, specifically, the present invention relates to a kind of double bundle conductor yoke plate picking-up device.
Background technology
The application of double bundle conductor in electrical network is more and more extensive, and double bundle conductor has the advantages such as the corona discharge of inhibition, minimizing line reactance and delivering power are large than single conductor., for improving the reliability of transmission line facility, after the faults such as insulator generation flashover, self-destruction, usually adopt indirect method to carry out isolator hot-line replacing.
Double bundle conductor, because the particularity of its structure must adopt specific purpose tool when carrying out replacing insulator under electrified, adopts double hook to carry the ply-yarn drill tool at present.In whole replacing operation process, the live line working personnel must wear screening clothing, and No. one the electrician is positioned at conducting wire hanging point top, cross-arm place, and main operation item is many; No. two the electrician is positioned at tower body inside conductor hanging point level place, and standing place is narrow and limited by the tower material.Double bundle conductor is connected with yoke plate by suspension clamp, by promoting yoke plate, promotes double bundle conductor, so that insulator string is not stressed, in order to it is changed.The thickness of yoke plate (being the double bundle conductor yoke plate) is generally 16-18mm, and the width of the U-shaped clamping plate opening of holder card only has 19mm, therefore carry out when in place at the holder card, the operation remaining of only having 1-3mm, operating personnel are difficult to aim in place, the holder card easily occurs collide with yoke plate and the problem such as be difficult for entering.
After the insulator string that straight line pole is changed is in place, need to catch on operating parts the latch draw ring (latch inserts in the yoke plate hole and prevents the U-shaped clamping plate sideslip of holder card) that holds in the palm on the U-shaped clamping plate of card, latch is withdrawed from from yoke plate, a whole set of jig just can be removed and get off to put to ground, completes whole replacing insulator string work.No. two electricians must use the above action bars of 5m to ask card to insert and move back the pin operation, and operating point can only be at the tail end of action bars, operating distance is far away, action bars is from great, all strengthened task difficulty, and latch draw ring aperture 10mm only, No. 2 electricians need spend the more time and could aim at draw ring and carry out the operating parts update, also often generation is inappropriate because of the angle of inserting draw ring, and occur that operating parts skids, and can't effectively to draw ring, move back the pin operation, affected greatly operating efficiency.
Replacing insulator under electrified operation meeting consuming time is very long for above-mentioned reasons, if the duration is longer, to cause the labour intensity of one, No. two electrician on tower to increase, especially meet the operation in summer, be easy to cause the muscle power overdraw, not only operating efficiency is not high, and the security risk while greatly having increased operation.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, easy to operate and double bundle conductor yoke plate picking-up device that efficiency is high.
For achieving the above object, technical scheme provided by the present invention is: double bundle conductor yoke plate picking-up device, it comprises the main hoisting bar of two parallel placements and is bolted on the connector of two main hoisting bar bottoms, it is characterized in that: the centre of connector is fixed with the U-shaped clamping plate of holder card (the U-shaped clamping plate opening upwards of holder card), mouthful place of drawing of the U-shaped clamping plate of described holder card is provided with interior chamfering, mouthful middle place of drawing of the U-shaped clamping plate of holder card has U-shaped groove, and the U-shaped clamping plate of described holder card are the left-right symmetric structure.
Have hole on the sidewall of the U-shaped clamping plate of described holder card.
The width of the U-shaped clamping plate opening of described holder card is 19mm.
The invention has the beneficial effects as follows:
1, the present invention makes interior chamfered (making it draw mouthful place's opening widens) to mouthful place of drawing that holds in the palm the U-shaped clamping plate of card, makes yoke plate directly slip into the U-shaped clamping plate of holder card by drawing a mouthful interior chamfering, has solved the difficult problem of inserting the holder card of yoke plate; The present invention also has U-shaped groove at mouthful middle place of drawing of the U-shaped clamping plate of holder card, cancelled the fixed form by latch and yoke plate, U-shaped groove directly is stuck on twin sockets on yoke plate, the generation of phenomenon of effectively having realized preventing breakking away (directly is fixed the twin sockets on yoke plate, the generation of phenomenon has just in time effectively realized preventing breakking away, connect equally firmly effectively, and it is quite rapid to operate, reliable).Of the present invention simple in structure, easy to operate and efficiency is high (operating time has dropped to 24 minutes).
2, the present invention has hole on the sidewall of the U-shaped clamping plate of holder card, can save material.
