Abstract
The utility model discloses a special clip for double-L and double-Y cross arms of extra-high voltage power transmission lines, which comprises an upper plate and a lower plate, wherein the upper plate has an inverted T-shaped structure, a mounting groove is formed in the middle of the upper plate, the upper plane of the lower plate is matched with the lower plane of the upper plate, a connecting hole is arranged in the lower end of the lower plate, and the upper plate is connected with the lower plate through a bolt. The special clip is simple, safe and convenient to use, and applicable to maintenance and overhaul of power transmission equipment on high-altitude and extra-high voltage power transmission lines.
Description
Technical field
The utility model relates to extra high voltage direct current transmission line maintenance, live line working Work tool field, particularly relates to the two L of a kind of UHV transmission line, two V cross-arm personality card.
Background technology
At present, along with the develop rapidly of power industry, long distance, Large Capacity HVDC Techniques become the cutting edge technology of big electrical network, and first extra high voltage direct current transmission line of China builds up, and will formally run.Extra high voltage direct current transmission line and existing 500kV extra high voltage network and the 1000kV AC extra high voltage transmission line that puts into operation in recent years relatively have substantial leaping.But because transmission line equipment is more on the circuit, so the suffered load of connection gold utensil on the transmission line is bigger, in Maintenance and Repair equipment and live line working process, must lay down this load earlier, lay down this load and just must find a stress point that intensity is high, yet operation all is the high-altitude to be carried out, and the construction preformed hole on the cross-arm side body of the tower is subjected to force intensity less, so be difficult to find a stress point that intensity is high during operation, therefore existing transmission facility and maintenance utensil all can not be satisfied the demand.
The utility model content
The purpose of this utility model is in order to overcome the deficiency of above-mentioned background technology, the two L of a kind of simple, safe and easy to operate UHV transmission line, two V cross-arm personality card to be provided.
In order to realize above purpose, the two L of a kind of UHV transmission line that the utility model provides, two V cross-arm personality card, it comprises upper plate and lower plate, upper plate is the inverted T-shape structure, and the middle of upper plate has the installation groove, match with the lower plane of upper plate in the last plane of lower plate, and the lower end of lower plate has connecting hole, connects by bolt between upper plate and the lower plate.
All be provided with reinforcement on described upper plate and the lower plate, increase the intensity of upper plate and lower plate.
Operation principle of the present utility model: stressed on the connecting hole of lower plate lower end is evenly distributed on the utility model and the face that angle bar on the cross-arm side body of the tower contacts by lower plate and upper plate, with stressed the stressed of face that change into of point, the intensity that can bear of stress point is naturally with regard to height like this.
The utility model is compared with the prior art, and shows that fully its superiority is: simple, safe and easy to operate etc.
Description of drawings
Fig. 1 is an assembly structure schematic diagram of the present utility model;
Fig. 2 is the plan structure schematic diagram of Fig. 1;
Fig. 3 is that the position of upper plate and lower plate concerns schematic diagram.
Among the figure: upper plate 1 lower plate 2 reinforcements 3 are installed the angle bar bossing 6 on the groove 4 connecting holes 5 cross-arm side bodies of the tower
Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail, but this embodiment should not be construed as restriction of the present utility model.
Present embodiment provides the two L of a kind of UHV transmission line, two V cross-arm personality card, it comprises upper plate 1 and lower plate 2, upper plate 1 is the inverted T-shape structure, and the middle of upper plate 1 has installs groove 4, match with the lower plane of upper plate 1 in the last plane of lower plate 2, and the lower end of lower plate 2 has connecting hole 5, connects by bolt between upper plate 1 and the lower plate 2.All be provided with reinforcement 3 on described upper plate 1 and the lower plate 2.
When the utility model uses, earlier upper plate 1 is installed on angle bar bossing 6 on the cross-arm side body of the tower by groove 4 is installed, with bolt lower plate 2 and upper plate 1 is connected and fixed then, the connecting hole 5 of lower plate 2 lower ends is the high stress point of intensity like this.Certainly the utility model can also a plurality ofly be arranged simultaneously and use.
