Abstract
The utility model discloses a large-tonnage conducting wire lifter, which comprises a hanging device. A pulley is arranged on the hanging device, a flexible rope is wound on the pulley, and two ends of the flexible rope are connected with protective hooks. The flexible rope is a steel wire rope. The large-tonnage conducting wire lifter utilizes alloy materials in total, is light in weight, convenient in carrying and easy in use, and reduces labor intensity of worker. The hook bodies are in flexible connection, and the hook bodies of the protective hooks are formed by aluminum parts and sealing coating and utilizes auto-locking hooks, thereby guaranteeing uniform stress in operation and guaranteeing safety and reliability. The utility model simplifies operation procedure and reduces operation strength of the workers.
Description
Technical field
The utility model relates to the line lifter field, especially relates to a kind of line lifter that is used for the large-tonnage lead.
Background technology
Along with the needs of the electrical network self-growth and the national economic development, according to the year two thousand twenty planning, China will form extra-high voltage grid.Ensure the safe and stable operation of 1000kV electrical network for it, press for summary, improve and research operation of power networks maintenance technology, especially carry out the research work of 1000kV extra high voltage line Work tool.
The 1000kV extra high voltage line has leaping of matter than the 500kV circuit, as the tower body of shaft tower, there is notable difference in cross-arm structure, window gap etc. with the 500kV circuit, and adopts eight bundle conductors, (300～550kN) insulators, insulator string assembling gold utensil structure also has bigger variation to large-tonnage.Iron tower is higher, the size of insulator and weight are bigger.Eight bundle conductor load are big, as adopt conventional Work tool, and operating personnel's operation is comparatively complicated, and efficient is low, and personnel and equipment are brought hidden danger.Therefore be badly in need of development 1000KV and simplify operation procedure, reduce labor intensity, increase work efficiency with wire lifting device.As adopt hard structure body, not only weight is big, and transportation and very inconvenience of use.
The utility model content
The purpose of this utility model is to provide a kind of wire lifting device in light weight, easy to carry, wieldy.
The technical solution of the utility model is:
A kind of large-tonnage wire lifting device, it comprises erecting by overhang, is provided with pulley on erecting by overhang, is wound with flexible rope on the pulley, the two ends of flexible rope are connected with the protection hook.
Described flexible rope is a steel wire rope.
The opening of described protection hook has the safety button that can form annular locking.
Described erecting by overhang comprises a pair of clamping plate, spacing is arranged and be provided with pulley between two clamping plate, and two clamping plate tops are connected with the suspension ring that are used to hang.
Described clamping plate are isosceles triangle, and the drift angle of isosceles triangle is the obtuse angle.
The utility model all adopts alloy material, and is in light weight, easy to carry, be easy to use, and alleviates worker's labour intensity.The coupler body employing is flexible coupling, and the coupler body of protection hook is that aluminum component adds the kiss-coating of sealing up a door, and adopts the automatic blocking hook, and is stressed even, safe and reliable when guaranteeing operation.Simplify operation procedure, reduced personnel operation intensity.Intensity height of the present utility model, light weight, safe and reliable, meet DL/T 463-2006 and GB/T 18037 relevant regulations, satisfy and carry out the requirement that promotes lead maintenance annex on the 1000kV circuit.The large-tonnage lead that the utility model is very suitable for the 1000kV circuit uses.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A view of Fig. 1;
Fig. 3 is the B-B view of Fig. 1.
Embodiment
As shown in Figure 1, 2, 3, the utility model comprises two clamping plate 1, and clamping plate 1 are isosceles triangle, and drift angle is the obtuse angle, and the centre of clamping plate 1 is provided with the hole, and two clamping plate 1 are parallel.Triangle highest point bolt at clamping plate 1 is connected with suspension ring 5.Suspension ring 5 are inverted U-shaped, and suspension ring 5 openings are connected with clamping plate 1 by bolt down.Be provided with spacer 4 below the junction, spacer 4 hollows are passed spacer 4 with bolt spacer 4 are fixed between two clamping plate 1, and suitable spacing can separate each other two clamping plate 1.
Being provided with 7, four pulley spindles 7 of four pulley spindles on the long limit of two clamping plate 1 successively is on the same line.Pulley spindle 7 passes clamping plate 1 and by bolt.Pulley 6 passes from pulley spindle 7, and rotates around pulley spindle 7.Pulley 6 is provided with groove.
Four steel wire ropes 2 are walked around from pulley 6 respectively, and the two ends of steel wire rope 2 are connected with protection hook 3 respectively, and the opening part of protection hook 3 is provided with safe button, and safe button can rebound automatically to guarantee the opening closure.Protection hook 3 belongs to prior art.
During use, suspension ring are hung up, protection hook 3 is pulled to suitable height respectively, each root lead of corresponding eight bundle conductors of difference, each lead of pull-up.
In addition, it is all slightly high or lower slightly than two pulley spindles between them 7 that the position of four pulley spindles 7 also can be similar to two pulley spindle 7 centers that are transformed to two ends, the left and right sides, on two pulleys 6 at two ends, the left and right sides, pass a slightly long steel wire rope, two middle pulleys 6 respectively pass short steel wire rope, so just can be used to mention sexfid lead.
Need to prove that at last line lifter also can be divided into two groups, difference is, only is provided with two pulleys 6 on every pair of clamping plate 1, also can mention eight bundle conductors with two groups like this.Approximate variation so also belongs to protection range of the present utility model.
