Abstract
The utility model relates to a bowl head hanging plate for a transmission line, belonging to the metal ware of ball bowl class in the transmission line. The utility model is provided with a pair of hanging plates (4), (5) of which the openings are downward, and the hanging plates are connected with a bowl head (1) to form an integral body and are symmetrically distributed in a Y shape; a connecting bolt (2) which penetrates through connecting holes of a pair of hanging plates is a Y-shaped bolt which forms an arc shape in an axial direction. The utility model has the advantages of flexible rotation, reasonable stress, long service life, etc., and the utility model is especially suitable for using when the transmission line is erected on districts of bad climatic condition and natural environment.
Description
The utility model relates to the ball bowl like gold utensil in the transmission line, especially is connected in the socket-clevis eye between insulator and the yoke plate.
Socket-clevis eye of the prior art, its a pair of link plate is parallel symmetrical distribution, angle between two link plates is 0 °, because yoke plate is to use Bolt Connection in the opening that is inserted between two link plates, when insulator string is subjected to the effect of wind-force and waves, the movement locus of socket-clevis eye and yoke plate is a camber line shape, be symmetrical arranged if a pair of link plate is parallel, attachment bolt can only be designed to linear, cause when waving, origination point contacts between attachment bolt and the hole, and is stressed unreasonable, cooperate badly, it is dumb that socket-clevis eye and yoke plate are rotated; On the other hand, lead expands with heat and contract with cold with variation of temperature, and the height and position of yoke plate is moved up and down, and also requires can rotate flexibly between yoke plate and the socket-clevis eye.
The purpose of this utility model provide in order to overcome above-mentioned weak point of the prior art just a kind of stressed rationally, rotate socket-clevis eye flexibly.
The purpose of this utility model is achieved by the following technical solution.
In the utility model, and the bowl head is linked to be for opening between a pair of link plate of one is the Y type down and is symmetrical arranged distribution, and attachment bolt is along its axial curved Y type bolt; Angle between two link plates is 0 °＜α≤70 °.
Because being the Y type, a pair of plate distributes, the centre is provided with angle α, and connecting bolt is circular arc type vertically, thereby do swing all around or because of lead expands with heat and contract with cold when yoke plate is moved up and down when insulator string, its swing camber line just matches with the axial circular arc line of connecting bolt, makes that formation face contacts between bolt and the hole, cooperate better, stressed reasonable, socket-clevis eye and yoke plate rotate nimbly and freely, and can prolong its useful life greatly.
Below in conjunction with drawings and Examples the utility model is further elaborated.
Fig. 1 is a front view of the present utility model,
Fig. 2 is a left view of the present utility model.
At first the method base of carbon constructional quality steel with forging and pressing is shaped, hot bending is a pair of link plate 4,5 that the Y type is symmetrically distributed again, curved angle α between 4,5 is 50 °, afterwards with the ball-and-socket part in the milling cutter processing bowl head, on link plate 4,5, bore connecting hole respectively again, the Y type connecting bolt 2 that forging is good pass 4,5 and yoke plate on connecting hole, mix nut 3 again and closed pin 6 gets final product.Confirm that through test the utility model has obvious superiority than prior art, rotate flexibly long service life.Be particularly suitable for using when the abominable area of weather conditions and natural environment erects power transmission lines.
Claims (2)
1, transmission line socket-clevis eye, form by bowl head (1), link plate (4), (5), attachment bolt (2), nut (3), it is characterized in that, and bowl head (1) is linked to be between a pair of link plate (4) for one, (5) opening and is the Y type down and is symmetrical arranged distribution, and attachment bolt (2) is axially to be the Y type bolt of arc along it.
2, socket-clevis eye according to claim 1 is characterized in that, the 0 °＜α of angle between two link plates≤70 °
