Description
Technical Field
The utility model relates to an extra-high voltage line insulator chain goes out string auxiliary device.
Background
The traditional power transmission line has long mileage, a large number of iron towers, frequent and large workload of line tower climbing maintenance operation, and the safety of the tower climbing maintenance operation is very important in China. At present, the distance between insulator strings of some ultrahigh voltage line strain towers in China is large and exceeds 1.2 meters; the length of the connecting structure of the insulator hardware string and the tower body is longer than 2 meters. When the operators go out of the insulator strings, the operators can only ride or crawl out along the single insulator string, and the high-altitude operators have great overturning danger. If the operation is carried out on a live line tower, the short electric clearance between the live line tower and the live equipment can be caused after the tower is overturned, so that the danger of electric shock is caused, and the life safety of operators is threatened.
Therefore, aiming at the ultrahigh voltage strain towers with large structures, operators are in urgent need of a safe, reliable and firm anti-falling safety protection auxiliary facility when coming out of an insulator string.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a simple structure, with low costs, safe and reliable, firm durable, special high voltage transmission lines insulator chain that can used repeatedly goes out string auxiliary device.
An extra-high voltage line insulator string discharging auxiliary device is characterized in that: the pull rod comprises a U-shaped hanging ring, a PT adjusting plate and a pull rod which are sequentially connected into a string, the other end of the pull rod is connected with a through hole in the middle of an angle steel, and connecting holes are respectively arranged at two ends of the angle steel.
Wherein a PT-type hanging plate is also connected between the PT adjusting plate and the pull rod.
The U-shaped hanging ring is detachably connected with the construction hole in the strain hanging point, and two ends of the angle steel are detachably connected with the two hanging racks on the top end of the insulator string respectively.
Wherein the pull rod is connected with the angle steel through a U-shaped suspension loop.
The utility model provides a simple structure, with low costs, safe and reliable, firm durable, repeatedly usable goes out insulator chain auxiliary structure. The advantages are that: 1. the safety and reliability anti-falling protection measure can be provided for the existing power transmission iron tower with an insulator string lacking safety protection auxiliary facilities; 2. the safety protection can be carried out on the operation of the operator in the string-out operation on the premise of not reforming the original structure of the iron tower hardware string; 3. the insulator string outgoing auxiliary connecting structure can be permanently used; 4. the use cost is low, and the popularization is facilitated.

Detailed Description
As shown in fig. 1, the extra-high voltage line insulator string discharging auxiliary device comprises a U-shaped hanging ring 3, a PT adjusting plate 4 and a pull rod 5 which are connected in sequence into a string, wherein the other end of the pull rod 5 is connected with a through hole in the middle of an angle steel 6, and connecting holes are respectively arranged at two ends of the angle steel 6.
Wherein still be connected with PT type link plate between PT adjusting plate 4 and pull rod 5, U type link 3 can dismantle with the construction hole 2 on strain insulator string 1 in addition and be connected, and 6 both ends of angle steel can dismantle with two stores pylon 7 on insulator string top respectively and be connected.
The utility model provides a go out insulator chain auxiliary structure, mainly in two gold utensil strings in the middle of add a string auxiliary connection structure, can ensure the balance of health with walking when making things convenient for the operation personnel to go out the cluster. The main connection mode is U-shaped hanging ring 3+ PT adjusting (adjusting) plate + PT hanging plate + pull rod 5+ angle steel 6.
The utility model discloses a use method and theory of operation are:
during the installation, in the work hole (the strain insulator hangs the construction hole 2 on the point 1) between tower body gold utensil cluster with 3 antithetical couplet of a U type link earlier, a U type ring of reconnection, the PT regulating plate of reconnection, the PT type link plate of reconnection, the one end of pull rod 5 of reconnection, the connecting hole of intermediate position on the angle steel 6 of direct or through the connection of U type ring between two set-angles boards (the stores pylon 7 on insulator chain top) again, be articulated in the middle of pull rod 5 and the angle steel 6, can adjust in the certain limit, the connecting hole at 6 both ends of angle steel passes through the fastener with two aforementioned set-angles respectively and is connected.
After the connection is finished, the tension degree of the auxiliary string is adjusted through the PT adjusting plate and the PT hanging plate, and the auxiliary string is ensured to have certain rigidity.
After the insulator string is taken out by an operator and a backup protection measure is taken, the balance of the operator can be kept by holding the auxiliary string (the pull rod 5 part) by hands, the danger of overturning can not occur, and the safety of the operator can be effectively protected in the whole operation process of the insulator string.
The auxiliary connection structure hardware fitting adopts a national grid standard structure, hot galvanizing corrosion prevention treatment is needed for processing iron pieces, and the auxiliary connection structure string length can be adjusted through the pull rod 5 with different lengths according to actual conditions aiming at iron towers with different voltage levels.
