Composite insulator bowl head anti-detachment hoop

technical field

The utility model relates to a composite insulator bowl head detachment preventing hoop.

Background technique

At present, the connection method of composite insulators for power transmission lines is as follows: the ball end of the composite insulator is connected to the bowl head, the M or R-shaped locking pin is installed in place, and connected with the wire connection fittings. However, due to special weather, the connection parts have the following problems. Breeze or Strong winds and other weather will cause slight movement at the connection between the ball head and the bowl head, and continue to squeeze or impact the locking pin up and down, left and right, causing the locking pin to deform and fail, and the ball head of the composite insulator will easily fall off from the bowl head. cause the line to trip.

The technical scheme adopted by the utility model is: a composite insulator bowl head anti-detachment hoop, which includes a lower hoop adapted to the shape of the bowl head, an upper hoop arranged on the lower hoop, and an upper hoop arranged on the upper hoop. The top tightening column and the connecting device arranged on the lower hoop and the upper hoop; the connecting device includes a lower connecting plate arranged at both ends of the lower hoop, an upper connecting plate arranged at both ends of the upper hoop, and a connecting plate for connecting the lower connecting plate and the bolts on the upper connecting plate; the jacking column is arranged on the inner side of the upper hoop and corresponds to the position of the locking pin on the bowl head.

A clamping device is arranged on the upper hoop.

The clamping device includes a left splint and a right splint, the left splint and the right splint are hinged through a connecting shaft, the left splint is provided with more than two left limit cards on the upper side of the connecting shaft, and the right splint is provided with two There are more than one right limit cards corresponding to the left limit cards, and clamp plates are arranged on the corresponding left limit cards and right limit cards.

The left clamping plate and the right clamping plate are provided with connecting surfaces for contacting with the inner wall of the U-shaped groove of the bowl head at the lower side of the connecting shaft.

The positive effect of the utility model is: the hoop is installed on the bowl head, and the pin mouth of the locking pin is locked by the top-tightening column, which can effectively prevent the composite insulator from falling out of the string and reduce maintenance costs; at the same time, the hoop is divided into upper and lower parts. part, both ends are connected by bolts and nuts, and the installation position can be adjusted according to the size of different bowl heads, which has high versatility; a clamping device is installed on the hoop, which can further increase the connection tightness of the hoop and prevent the hoop from falling off. The clamping device is provided with a corresponding limit card on one side of the connecting shaft, and a clamping plate is provided between the corresponding limit cards, which can adjust the clamping force of the clamping device and effectively prevent the hoop from falling off.

detailed description

As shown in accompanying drawings 1 and 2, the utility model includes a lower hoop 1 adapted to the shape of the bowl head, an upper hoop 2 arranged on the lower hoop 1, a top tightening column 6 arranged on the upper hoop 2 and The connecting device arranged on the lower hoop 1 and the upper hoop 2; the connecting device includes a lower connecting plate 4 arranged at both ends of the lower hoop 1, an upper connecting plate 3 arranged at both ends of the upper hoop 2 and a connecting plate for connecting the lower Plate 4 and the bolt 5 of the upper connecting plate 3; the clamping column 6 is arranged on the inner side of the upper hoop 2 and corresponds to the position of the locking pin on the bowl head.

A clamping device is provided on the upper hoop 2, and the clamping device includes a left splint 8 and a right splint 7. The left splint 8 and the right splint 7 are hinged through a connecting shaft 12, and the left splint 8 is connected to the connecting shaft. The upper side of 12 is provided with more than two left limit cards 9, is provided with more than two right limit cards 13 corresponding to left limit cards 9 on the right clamping plate 7, and is arranged on the corresponding left limit cards 9 and right limit cards. The card 13 is provided with a clamping plate 10, one end of the clamping plate 10 is clamped with the left limit card 9, and the other end is clamped with the right limit card 13. On the lower side of the connecting shaft 12, the left clamping plate 8 and the right clamping plate 7 are provided with connecting surfaces for contacting with the inner wall of the U-shaped groove of the bowl head.
