Description

Transmission line of electricity straight line pole aerial earth wire overhauls stent
Technical field
It the utility model is related to a kind of electric power overhaul instrument, and in particular to a kind of transmission line of electricity straight line pole aerial earth wire maintenance Stent.
Background technology
At present, in the maintenance of transmission line of electricity straight line pole aerial earth wire, overhead ground wire suspension clamp is replaced, and it is aerial replacing During ground wire, straight line is mainly fixed on the head of the mast towards top sheave with steel wire rope and cord holder, due to the ground line-spacing head of the mast 30 Centimetre, away from eyelet bolt (15 centimetres of hanging wire point), adjustable operable space is limited, inspection operation and hanging wire operation, time-consuming and laborious, General two hours of two people can just hang up line.Simultaneously because the head of the mast does not have hanging point, cord holder steel wire rope is carried on the back in the head of the mast Stringing easily comes off, and jeopardizes operating personnel.
Utility model content
Technical problem to be solved in the utility model is existing steel wire rope and cord holder replacement aerial earth wire catenary Press from both sides and easily come off when replacing aerial earth wire, there are security risk, while hanging position abuts electric pole and eyelet bolt, shadow Inspection operation and hanging wire operation are rung, its purpose is to provide a kind of transmission line of electricity straight line pole aerial earth wire to overhaul stent, the stent Aerial earth wire suspension height can be arbitrarily adjusted, and operating position can be avoided, it is time saving and energy saving, improve work efficiency more than 2 times;At the same time The security risk that can prevent messenger wire steel wire rope from coming off.
The utility model is achieved through the following technical solutions:
Transmission line of electricity straight line pole aerial earth wire overhauls stent, including hanger, and the hanger side wall, which is provided with, to be used for and electric pole The anchor ear of connection, hanger top are provided with pulley blocks, Overline ring and anchor ring, and Overline ring and anchor ring are arranged on the cunning of pulley blocks Between wheel, pulley blocks are located above anchor ear, and hanging wire ring is provided with hanger side wall.Examined for the aerial earth wire of current power transmission circuit Since adjustable operable space is limited when repairing, inspection operation and hanging wire operation are time-consuming and laborious, and general two hours of two people could hang Reach the standard grade.Simultaneously because the head of the mast does not have hanging point, the cord holder steel wire rope back of the body easily comes off in head of the mast stringing, jeopardizes operator The problem of member, the stent of this programme design, hanging position after being fixed with electric pole, is increased, can adjust at the same time by hanger Right position is hung, avoids eyelet bolt and hitch point, and lifting steel wire is placed restrictions on using the corresponding anti-skid device of pulley blocks The position of rope, prevents steel wire rope from slipping, and steel wire rope is driven using tractor, by pulley blocks and main suspension hook, adjusts and is slided towards skyhook Wheel, so as to arbitrarily adjust aerial earth wire hanging position.Realized by hanger and steel wire rope is got around into operating position, it is time saving and energy saving, carry More than 2 times of high workload efficiency, when maintenance, can arbitrarily adjust suspension height and prevent ground wire from slipping, and protect equipment and the peace of personnel Entirely.
Further, hanger includes level frame and vertical frame, and level frame is vertical with the side wall of vertical frame fixes, Overline ring It is installed on anchor ring on the top surface of level frame, anchor ear and hanging wire ring are installed on the symmetrical side wall of vertical frame, and anchor ear It is located at hanging wire ring below level frame.By this structure design, the fixation with electric pole side wall can be realized, and along electric pole Top is around the opposite side for reaching electric pole so that the installation site of steel wire rope adjusting position and aerial earth wire will not interfere with, it is convenient into Row adjusts and maintenance.
And pulley blocks include rotating pulley one and rotate pulley two, rotate pulley one and be installed on vertical frame, rotate pulley Two are installed on level frame, rotate pulley one and are located above level frame, and Overline ring and anchor ring are arranged on and rotate pulley one and turn Between movable pulley two, between Overline ring is arranged on anchor ring and rotates pulley two, the one end of level frame away from vertical frame is provided with Mounting bracket, rotates pulley two and is arranged in mounting bracket, be provided with Antisliding bolt in mounting bracket, and rotate pulley two be arranged on it is anti- Between sliding bolt and level frame.The adjusting to steel wire rope is realized by two rotation pulleys, so that the height to aerial earth wire Adjusted, and it is easy to adjust, overhaul efficiency is improved, while Antisliding bolt also avoids the occurrence of slipping phenomenon, ensure that The security of maintenance.
Be stably installed to realize on electric pole, the quantity of anchor ear is preferably two, and anchor ear is U-shaped, so with electricity Bar outer wall contact area bigger, two anchor ears are arranged on same plumb line, and two anchor ears are arranged at level frame and vertical frame In the inside region of formation, hanging wire ring is arranged between two anchor ears, and so stent can keep stable when in use, will not shake It is dynamic.U-shaped anchor ear and M parallels is detachable part, can be replaced according to pole diameter.
The utility model compared with prior art, has the following advantages and advantages:The stent can any adjustment frame Vacant lot line suspension height, and operating position can be avoided, it is time saving and energy saving, improve work efficiency more than 2 times;It can prevent messenger wire steel at the same time The security risk that cord comes off.
