Abstract

The invention provides a double split wire line maintenance pulley which comprises an upper wire iron pulley and a lower wire iron pulley, wherein the upper wire iron pulley and the lower wire iron pulley are connected with a ladder head. The upper wire iron pulley and the lower wire iron pulley are respectively provided with an anti-separating device, wherein the anti-separating devices prevent the upper wire iron pulley and the lower wire iron pulley from separating from upper and lower wires. A foldable seat is fixed on the ladder head. A parachute pack is arranged below the foldable seat. According to each anti-separating device, a pulley is fastened on a wire and is inserted into an anti-separating pin. According to the device provided by the invention, when wire outgoing is carried out, a maintenance worker can sit to work; the parachute pack is arranged below the seat; the work intensity of the operator can be reduced; the work efficiency is improved; when the worker encounters a dangerous situation, the worker can open the parachute pack to escape; and the double split wire line maintenance pulley is especially suitable for the maintenance of a river-crossing district and a large span district, and can be widely used as a transmission line maintenance device.

Description

Twin bundled lines maintenance coaster

Technical field

the present invention relates topower transmission lines overhauling equipment.

Background technology

At present, voltage class of electric power system generally raises, and in order to improve conveying capacity, realizes national network, meets the demand of work, agricultural and resident living power utility, and transmission line generally adopts double bundle conductor to improve the reliability of power delivery capabilities and power supply.In circuit long-time running in the wild, due to a variety of causes, as natural calamity, outside destroy etc., need the workload of maintenance very large, staff's human body when double bundle conductor work outlet can only be sought connections with on a wire, because the weight of human body is exerted pressure to upper conductor, cause upper conductor twisting, wave the personnel that cause and cannot carry out normal outlet maintenance work, key area Kua Jiang location particularly, the large location of crossing over cannot be overhauled in time, in order to address this problem, people have done multiple effort, as disclosing a key name for No. 201220512732.5, Chinese patent is called the technology that vertical double bundle conductor overhauls coaster, introduced a kind of by pillar, on pillar, be provided with the device of pulley hanging feet assembly and seat module composition, described pulley hanging feet assembly comprises two bar foot rests that vertically distribute, in two described bar foot rests, be all equipped with an axis, on two described axis, be equipped with pulley, between two described bar foot rests, connect a telescopic connecting rod, by two hitching leg structures, can stablize the spacing of upper lower wire, according to the spacing between different conductor, can adjust distance between two hanging feets simultaneously.This device can solve double bundle conductor and overhaul rare problem, but also exist maintenance worker stand in vertical longevity of service labour intensity large, there is no defects such as safe device.Address these problems and become urgent need.

the content of invention

In order to overcome the deficiencies in the prior art, design a kind of maintenance worker and can sit above it just maintenance, twin bundled lines maintenance coaster that operating efficiency is high.It comprises upper conductor iron block, the lower wire iron block being connected with ladder head twin bundled lines maintenance coaster, upper conductor iron block, lower wire iron block are respectively with the anti-drop device that prevents that itself and upper lower wire from departing from, on ladder head, be fixed with foldable base, landing pack is housed below foldable base, and said anti-drop device is to form by coaster being buckled on upper conductor, insert locking pin.Use this the device of invention canduring outlet, maintenance worker's energy sedentary and seat have landing pack below, not only can alleviate operator's working strength, increase work efficiency, and can release a parachute bag escape of situation about facing a danger, be specially adapted to, across location, river, cross over greatly the maintenance in location.

Accompanying drawing explanation

Fig. 1 is double bundle conductor line-outgoing pulley view.

Embodiment

This a most preferred embodiment of invention, as figure,it comprises upper conductor iron block 1, the lower wire iron block 3 being connected with ladder head 5 double bundle conductor line-outgoing pulley, upper conductor iron block with prevent anti-drop device that itself and upper conductor depart from, this anti-drop device by coaster being buckled on upper conductor, insert locking pin 2 and form, lower wire iron block is with the anti-drop device that prevents that itself and lower wire from departing from, this anti-drop device is to form by coaster being buckled on upper conductor, insert locking pin 4, on ladder head, be fixed with foldable base 6, landing pack 7 is housed below foldable base.This the using method of invention is:when double bundle conductor overhauls, by one group of 3 people, carry out cooperating, one people is with rope to seek connections with cross arm of tower place, hang up iron block, another people seeks connections with wire place by insulator, by ground handling personnel, double bundle conductor coaster is toggled and is passed to wire place with rope, by the staff of wire place, upper conductor iron block is buckled and on upper conductor, is plugged locking pin, lower wire iron block buckles and on lower wire, is also plugged locking pin, after boarding head is connected and fixed with wire coaster, is plugged locking pin.By a staff, down to the sub-head of boarding, after fastening backup protection rope, fastening seat belts, open foldable base, be sitting in and in foldable base, carry out voluntarily service work.If run into accident, can take out the parachute escape that foldable base is equipped with below.

Claims (2)
