Abstract
The utility model provides a clamping device for replacing a strain insulator string of a twin bundle conductor, which relates to the repair and maintenance tools of power transmission lines, in particular to a clamping device which is used for replacing a strain insulator string 2 of the twin bundle conductor. The clamping device is formed by overlaying of a main clamping plate 8, a middle backing plate 9 and a fixing plate 10, which are connected by fixing bolts 5 and are fixed on a square yoke plate 3 of the twin bundle conductor so as to form one fulcrum of a temporary pulling rope 7; and the other fulcrum of the temporary pulling rope can be provided by a spindle-shaped clamping device 6 of the prior art which matches with a triangle cross arm 1 so as to form the tension system of the temporary pulling rope. The insulator string can be easily replaced only by straining the temporary pulling rope, thus the device has the characteristics of easy operation, flexibility and convenience and safety and reliability.
Description
Technical field
The utility model relates to power transmission line maintenance and worker's accessory of safeguarding, particularly belongs to a kind of jig that is used to change the double bundle conductor strain insulator string.
Background technology
In power transmission system, for transmission capacity that increases circuit and the security reliability that improves power supply, transmission line adopts the double bundle conductor form more and more at present.Along with the increase of running time, null value appears in the insulator string in the transmission line, or causes contamination serious because of being in the heavily contaminated area.For guaranteeing the safe and reliable of transmission line, need in time to change above-mentioned null value or the serious insulator string of contamination.But, owing to lack and the supporting special mould clamp of the square yoke plate of double bundle conductor, make the replacing of insulator string become very difficult, waste time and energy, and have potential safety hazard in the course of the work.
Summary of the invention
The purpose of this utility model promptly is to provide a kind of novel double bundle conductor strain insulator string to change jig, can with the supporting use of square yoke plate of double bundle conductor, change the purpose that insulator string is convenient and swift, save labor to reach.
Double bundle conductor strain insulator string replacing jig disclosed in the utility model is fixed on the square yoke plate of double bundle conductor, thereby constitutes a fulcrum of interim pulling rope, is formed by stacking by main card plate, intermediate pads and fixed head.Described intermediate pads places in the medial launder of square yoke plate, and main card plate and fixed head are placed in the both sides of square yoke plate respectively.Between main card plate, intermediate pads and the fixed head, connect by set bolt.
Double bundle conductor strain insulator string disclosed in the utility model is changed jig, can constitute a fulcrum of interim pulling rope after being fixed on the square yoke plate of double bundle conductor, and another fulcrum of interim pulling rope can by of the prior art, provide with the supporting fusiformis jig of triangle cross-arm, thereby constitute the clamping system of interim pulling rope.When changing insulator string,, therefore has easy to operate, flexible convenient and safe and reliable good effect as long as, can easily change with interim pulling rope tension.
Description of drawings
Accompanying drawing partly discloses specific embodiment of the utility model, wherein:
Fig. 1, double bundle conductor strain insulator string normal mounting schematic diagram;
Scheme of installation when Fig. 2, the utility model are used for the replacing of double bundle conductor strain insulator string;
Fig. 3, main card plate structure schematic diagram of the present utility model;
Fig. 4, intermediate pads structural representation of the present utility model;
Fig. 5, fixed head structural representation of the present utility model;
Fig. 6, A-A is to view.
Embodiment
As shown in Figure 1, the utility model at double bundle conductor strain insulator string 2, be installed between triangle cross-arm 1 and the square yoke plate 3, there is medial launder 4 in the central authorities of square yoke plate 3.As shown in Figure 2, in the prior art, have and triangle cross-arm 1 matching used fusiformis jig 6, can be more changes jobs need with interim pulling rope 7 fulcrum is provided.The utility model then with the square yoke plate 3 supporting uses of double bundle conductor, constitute another fulcrum of interim pulling rope 7.
As Fig. 3～shown in Figure 6, the utility model is made of a main card plate 8, intermediate pads 9 and fixed head 10, and the three is bound up by set bolt 5.When installing with square yoke plate 3, intermediate pads 9 places in the medial launder 4 of square yoke plate, plays rotation of main card plate and the effect of bearing interim pulling rope 7 main pulling force of preventing; Main card plate 8 and fixed head 10 are placed in the both sides of square yoke plate respectively, play the effect of stable and fixed connection.
The utility model is after installing with square yoke plate 3, and with interim pulling rope tension, the tension force that strain insulator string is born is eliminated, then can be easily with its replacing.
