Abstract

The utility model discloses a combined spare protective rope for a double and a quarter division leads, which comprises a cable wire sleeve (1), a protective rope body (2) and a lead bracket (3), wherein, the two ends of the cable wire sleeve(1) are provided with shackles (4); the upper end of the protective rope body (2) is hung and connected to the middle position of the cable wire sleeve (1), the lower end is fixedly connected with the lead bracket (3); the two ends of the top part of the lead bracket (3) are fixed with hooks I (5), the hook bodies of which are provided with reverse lockpins I (6); the two ends of the bottom of the lead bracket (3) are fixed with detachable hooks II (7) the hook bodies of which are provided with reverse lockpins II (8). The protective rope is applied to the linear pole repair spare protection for 220 kv double and quarter division circuit erection and has the characteristics that the strength is high, the weight is light, the carrying is convenient, the operation efficiency is high, and the protective rope is safe and reliable.

Description

Composite type is two, conductors on quad bundled backup protection rope

Technical field

The utility model relates to the protective device of lead in a kind of transmission line, is specifically related to a kind of two, conductors on quad bundled backup protection rope.

Background technology

Power transmission lines overhauling rules regulation is changed on the straight line pole when porcelain vase, composite insulator or repacking are two goes here and there and must be used backup protection, prevents that pull tool is malfunctioning to cause lead to fall and human casualty accident because of hanging.And, along with putting into operation of the two divisions of 220kV, quadripartion circuit, must carry out such circuit repair and maintenance, change work such as synthetic insulator.But do not have two divisions, the special-purpose backup protection rope of quadripartion line maintenance at present, can only use two, four single conductor line backup protection ropes respectively, it exists simple in structure, and is easily aging, intensity difference; Cross-arm side hanging point is simple and crude, and is easily loosening, and lead hanging point place hook is simple and easy, and no locking device is easily deviate from, the shortcoming that coefficient of safety is low, and repetitive operation, rope is miscellaneous, and the operating time is long, not only increases work high above the ground labour intensity, and increases potential safety hazard.

Summary of the invention

For solving the problem of above existence, the utility model provides that a kind of composite type is two, conductors on quad bundled backup protection rope, and its technical scheme of taking is:

This protection rope comprises steel wire loop, protection rope rope body and wire support; the steel wire loop two ends are provided with shackle; protection rope rope body upper end is articulated in the centre position of steel wire loop; the fixedly connected wire support in its lower end; the two ends, top of wire support are fixed with hook I; the coupler body of hook I is provided with locks pin I in, and the two ends, bottom of wire support are fixed with dismountable hook II, and the coupler body of hook II is provided with locks pin II in.

Hook I is last anti-formula hook, and hook II is the hook-type hook.

The hook part of this protection rope detachably is used in combination, and is common to two, conductors on quad bundled, and the hanging wire point of hanging wire part adopts double hanging point, alleviates angle bar pulling force and guard arm, and suspension centre partly can free hanging wire, automatic blocking.This protection rope is applicable to two divisions of 220kV and quadripartion construction of line straight line pole maintenance backup protection, can different circuits, and the location on, dismantle according to the different needs independent assortment.Have the intensity height, in light weight, carry light, operating efficiency height, safe and reliable characteristics.

Description of drawings

Accompanying drawing is a structural representation of the present utility model.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described:

As shown in the figure, the lead of different quality makes the protection rope pulling force difference of bearing, thus on hanging point, adopt the two hanging points later of steel wire loop, both fixedly shackles 4 of steel wire loop 1 two ends, this hanging point can make cross-arm stressed evenly, improves protection rope reliability.

Set up selection different model steel wire rope as protection rope rope body 2 according to difference, steel wire rope is made cover up and down, and last cover is articulated in the centre position of steel wire loop 1, the fixedly connected wire support 3 of trapping, so easy to connect, change when being easy to breakage, guarantee the complete of instrument.

Wire support 3 adopts high-strength aluminum alloy, and delta bolt is formed by connecting, and is light durable, corrosion-resistant.Because two divisions all are 400mm with the wire spacing that conductors on quad bundled sets up, so wire support 3 can be general.The two ends, top of wire support 3 install and fix anti-formula hook I5, and two ends, tool bottom install and fix dismountable hook-type hook II7, and two kinds of hooks fully guarantee the conductors on quad bundled secure fixation.The coupler body upper end of hook I5 is installed and is locked pin I6 in, and the coupler body upper end of hook II7 is installed and locked pin II8 in, locks in a kind ofly to adopt general single hook to lock another kind of the use for special quadripartion in to go up anti-formula back of the body hook and lock in.

When this protection rope uses on double bundle conductor; at first steel wire loop 1 one end shackles 4 are hung to the inside about 40cm of cross-arm 9 points; tangled lead and lock with hook I5 by the lower wire personnel again and lock pin I6 in, avoid lead to deviate from, suspension centre does not influence maintenance from the about 1m of setting.When this protection rope uses on conductors on quad bundled; at first steel wire loop 1 two ends shackle 4 is separately fixed at cross-arm 9 two ends; protection rope rope body 2 hangs over steel wire and overlaps 1 centre position; tangle lead and lock down pin with hook I5 and hook II7 respectively by the lower wire personnel again; avoid lead to deviate from, suspension centre does not influence maintenance from the about 1m of setting.

Claims

1; a kind of composite type is two; conductors on quad bundled backup protection rope; comprise steel wire loop (1); protection rope rope body (2) and wire support (3); it is characterized in that: steel wire loop (1) two ends are provided with shackle (4); protection rope rope body (2) upper end is articulated in the centre position of steel wire loop (1); the fixedly connected wire support in its lower end (3); the two ends, top of wire support (3) are fixed with hook I (5); the coupler body of hook I (5) is provided with locks pin I (6) in; the two ends, bottom of wire support (3) are fixed with dismountable hook II (7), and the coupler body of hook II (7) is provided with locks pin II (8) in.

2, two, the conductors on quad bundled backup protection rope of composite type according to claim 1 is characterized in that: hook I (5) is last anti-formula hook, and hook II (7) is the hook-type hook.
