Anti-drop socket-clevis eye

Abstract

The invention discloses an anti-drop socket-clevis eye which belongs to connection devices of high-voltage line hardware and mainly overcomes the defect that a ball head of a ball head hanging ring is easy to eject from the socket-clevis eye as a spring bolt structure is not reasonable in the traditional socket-clevis eye. The anti-drop socket-clevis eye comprises a socket-clevis eye which is provided with a jack and an inverted T-slot, wherein the jack is communicated with one end of the inverted T-slot. The anti-drop socket-clevis eye is characterized by also comprising an anti-drop baffle plate and fastening bolts, wherein the anti-drop baffle plate comprises a bottom plate and a vertical plate connected with the upper side of the bottom plate, the fastening bolts are used for connecting the socket-clevis eye with the anti-drop baffle plate, a bolt bottom plate through hole is arranged at one end of the bottom plate, a lug boss which is provided with a bolt hanging plate through hole is arranged at the notch end of the inverted T-slot of the socket-clevis eye, the other end of the bottom plate and the vertical plate are respectively positioned in the jack of the socket-clevis eye and at the notch end of the inverted T-slot, and the fastening bolts are positioned in the bolt bottom plate through hole and the bolt hanging plate through hole. The invention has the advantages of simple structure, convenient disassembly, assembly and overhauling and good anti-drop effect.

Description

technical field [0001] The invention belongs to a connection device for high-voltage electric line fittings, in particular to an anti-off bowl head hanging plate for connecting with a ball-end hanging ring of high-voltage electric line fittings. Background technique [0002] In order to prevent the ball hanging ring from coming off the bowl hanging plate, the existing bowl hanging plate is provided with an anti-falling device made of a spring latch of a stainless steel flat steel profiled structure. When the ball hanging ring and the bowl hanging plate are in a vertical state or the inclination angle is not large, under the action of gravity and the locking force of the spring bolt, the ball hanging ring is difficult to fall off from the bowl hanging plate. However, because the high-voltage power line has been in a very harsh natural environment in the wild for a long time, under the alternating action of strong winds such as hurricanes, impact friction will continue to occu...

AI Technical Summary

Problems solved by technology

However, because the high-voltage power line has been in a very harsh natural environment in the wild for a long time, under the alternating action of strong winds such as hurricanes, impact friction will continue to occur due to 1) the ball head of the ball ring and the facade of the spring bolt The facade of the spring bolt is severely worn and broken off, causing the ball head to escape from the inverted T-shaped groove of the bowl head hanging plate; or 2) the huge longitudinal friction force generated when the ball head of the ball head hanging ring swings or moves The hook head of the spring bolt is deformed or broken, causing the ball head to come out of the inverted T-shaped groove of the bowl head hanging plate

It may also be due to the loss of elasticity of the material of the spring pin and the restriction on the ball head, causing the ball head to come out of the inverted T-shaped groove of the bowl head hanging plate

In a word, due to the unreasonable structure of the existing spring latch, it will cause a safety accident in which the ball head of the ball head hanging ring comes out of the bowl head hanging plate, and the high voltage line will suffer heavy losses.
