Abstract
The utility model discloses a fixture for replacing an overhead transmission line strain insulator string, which comprises a fixture body. The utility model is characterized in that the fixture body comprises a front body (1) and a back body (2), which are connected. a long opening (3) is arranged in the front body (1) and at the front part of the back body (2). The front end of the front body (1) and the joint of the front body (1) and the back body (2) are respectively provided with a bolt (4). The back end of the back body (2) is provided with a connecting hole (5). The utility model has the advantages of simple and convenient operation and high safety performance, reduces the labor intensity of working staff and improves the work efficiency.
Description
Technical field:
The utility model relates to a kind of replacing strain insulator string on overhead transmission line jig, belongs to electric power system overhead transmission line maintenance field.
Background technology:
Along with economic society constantly develops, the continuous quickening of power grid construction speed, the transmission line transmission capacity improves constantly, and new material new process is constantly used, and maintenance has proposed requirements at the higher level to overhead transmission line, and the transmission line safe and reliable operation is particularly important.
At present, the processing of the impaired class defective of aerial power transmission line insulator, the mode of mainly taking has three kinds, promptly uses the strand mill, adopts chain block and utilizes the method for jig to handle.First kind of mode, tool using is many and loaded down with trivial details, labour intensity is big, needs with many people co-operation, and this method seldom is employed; Second method adopts chain block, and the method that adopts 5t chain block two strings to sling is simultaneously changed, and this method heaviness and workload are big, poor stability, and efficient is low, and replacing a slice damaged insulator is finished jointly by 12 staff needs more than 4 hour work; The third method utilization is changed the strain insulator string combination tool and is singly strung the replacing of hanging, and is one of method comparatively commonly used at present, still, because the limitation of its jig only is applicable to L type yoke plate, and is not suitable for LF type yoke plate.
The utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides a kind of easy and simple to handle, security performance height, the replacing strain insulator string on overhead transmission line jig that alleviates intensity of workers, increases work efficiency.
The purpose of this utility model can reach by following measure: a kind of replacing strain insulator string on overhead transmission line jig, it has jig body, it is characterized in that body is connected as a single entity after jig body is by jig precursor and jig constitutes, the front portion of body is provided with long opening in the jig precursor and behind the jig, the junction of body is respectively equipped with bolt behind the front end of jig precursor and jig precursor and the jig, and the rear end of body is provided with connecting hole behind the jig.
In order further to realize the purpose of this utility model, the angle behind described jig precursor and the jig between the body is 150 °-170 °.
The utility model can produce following good effect compared with the prior art: the utility model is used to change the strain insulator string combination tool, singly strings to hang that to change strain insulator string easy and simple to handle the security performance height; Change a slice damaged insulator and shorten to 1 hour workload of 5 people, improved operating efficiency greatly, alleviate intensity of workers, increase work efficiency, and safety has obtained bigger guarantee.Promptly be applicable to L type yoke plate, be applicable to LF type yoke plate again.
Table 1 is changed the analysis contrast table of strain insulator string for adopting prior art and the utility model:
Table 1
| Type | Fail safe | Economy | Flexibility | Operability | Environmental requirement | Total points |
| Adopt the 5t chain block | 80 | 60 | 80 | 90 | 70 | 380 |
| Use the strand mill | 70 | 40 | 40 | 60 | 30 | 240 |
| The utility model | 95 | 100 | 90 | 100 | 85 | 470 |
Table 2 is reference for the damaged insulator of finding with silkworm route and two circuits of light path line, handles the efficient and the economic comparison table of the impaired defective of insulator with " using the operation of 5t chain block method " and " utilizing the utility model to change " two kinds of operational methods:
Table 2
| Line name | Operational method | The defective number | Treating number | Time spent |
| One two wires, silkworm road | Use the 5t chain block | 3 | 3 | 13 hours |
| Light path one two wires | The utility model | 24 | 24 | 21 hours |
By above-mentioned statistical form as can be seen, after having used the utility model, operating efficiency significantly improves, and saves a large amount of manpower and materials simultaneously, only saves interruption duration more than 8 hour, creates economic benefit more than 20 ten thousand.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Embodiment: embodiment of the present utility model is elaborated below in conjunction with accompanying drawing:
Embodiment: a kind of replacing strain insulator string on overhead transmission line jig (referring to Fig. 1, Fig. 2), has jig body, jig body by jig precursor 1 and jig after body 2 be connected as a single entity and constitute, angle behind jig precursor 1 and the jig between the body 2 is 150 °-170 °, the front portion of body 2 is provided with long opening 3 in the jig precursor 1 and behind the jig, the junction of body 2 is respectively equipped with bolt 4 behind the front end of jig precursor 1 and jig precursor 1 and the jig, and the rear end of body 2 is provided with connecting hole 5 behind the jig.During use, with the utility model by connecting hole 5 with the leading screw of changing the strain insulator string combination tool or lead chain and is connected, 4 fastening with tighting a bolt in L type yoke plate or the long opening 3 of LF type yoke plate insertion.
Claims (2)
1. change the strain insulator string on overhead transmission line jig for one kind, it has jig body, it is characterized in that after jig body is by jig precursor (1) and jig body (2) formation that is connected as a single entity, the front portion of body (2) is provided with long opening (3) in the jig precursor (1) and behind the jig, the junction of body (2) is respectively equipped with bolt (4) behind the front end of jig precursor (1) and jig precursor (1) and the jig, and the rear end of body behind the jig (2) is provided with connecting hole (5).
