Description

U-shaped hanging ring

Technical Field

The utility model relates to an electric power fitting technical field particularly, relates to a U type link.

Background

The U-shaped hanging ring is a U-shaped hardware tool which is formed by combining the hanging ring and the hanging plate connecting piece respectively at two ends of a power supply line, and various specifications have great use, safety, convenient use and durability in the hoisting process. Although the U-shaped suspension loop is simple, the breaking of the U-shaped suspension loop in the power equipment leads to the breaking of the high-voltage wire, and the resulting consequences are not reasonable, and the analysis of the existing documents shows that: the fracture reason is that the matching deviation exists between the U-shaped hanging ring and the ball head hanging ring, when the ball head hanging ring is excessively tightened and clamped, the tension on two sides is larger and larger, when the ball head hanging ring is slightly tightened and clamped, a worker slightly smaller in the ball head hanging ring pre-tightens the bolt, the pressing force on two sides is larger, and under the two conditions, the stress generated at the bottom of the hanging ring is larger and larger, so that a crack source is generated at the bottom of the hanging ring, and the hanging ring is brittle fracture. And in the use of actual high-voltage electric tower power equipment, the U-shaped link often receives the strong wind influence and can collide and rub rather than the connecting piece, can produce crackle or wearing and tearing, and then can fracture.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a U type link, its both sides that can prevent U-shaped link produce tension or packing force to can reduce wear and tear and share partial pulling force downwards, with solving current problem.

The embodiment of the utility model discloses a realize through following technical scheme:

a U-shaped suspension loop comprising: ring body, sleeve and commentaries on classics pressure cover are hung to the U type, the sleeve sets up the bolt hole department at ring body U type mouth is hung to the U type, the commentaries on classics pressure cover includes: the grinding and pressing device comprises a grinding and pressing sleeve, a connector and a pressing ring, wherein the grinding and pressing sleeve is sleeved at the bent part of the U-shaped hanging ring body, the pressing ring is sleeved on the inclined plane at the middle upper part of the U-shaped hanging ring body, the annular surface in the pressing ring is also an inclined plane correspondingly matched with the contact, and the connector is arranged between the grinding and pressing sleeve and the pressing ring.

The grinding and pressing sleeve is in a U-shaped sleeve, and a notch is formed in the lower surface of the grinding and pressing sleeve.

The size of the gap is half of the upper semicircular pipe part of the grinding and pressing sleeve.

The connecting body is a spring, and the spring is in a tightening state.

Flanges are arranged at two ends of the sleeve.

The length of the sleeve is equal to the width of a U-shaped opening on the U-shaped hanging ring body.

The pressure ring has two.

The material of grinding and pressing the cover is wear-resisting steel, the sleeve material is withstand voltage steel.

The utility model discloses technical scheme has following advantage and beneficial effect at least:

the utility model discloses increased sleeve and commentaries on classics pressure cover on current U type link, simple to operate, simple and practical can inject connecting piece contact range when hanging and put the connecting piece, prevents that the both sides of U-shaped link from producing tension and packing force to avoid link bottom brittle fracture. And the rotating pressing sleeve changes the lower pulling force from the direction changed by the inclined surface of the original middle upper part of the U-shaped hanging ring into pressing force and is mutually abutted against the sleeve, so that the downward pulling force of the part can be shared, the service life of the U-shaped hanging ring is prolonged, and meanwhile, the sleeve and the rotating pressing sleeve are made of pressure-resistant steel and wear-resistant steel, the U-shaped hanging ring is prevented from being directly contacted with a connecting piece, and the generation of cracks and abrasion are reduced.

Detailed Description

Referring to fig. 1, a partially shielded outline adopts a dotted line, and a U-shaped suspension loop includes: the U-shaped ring body 1, sleeve 2 and commentaries on classics pressure sleeve 3 hang, sleeve 2 sets up 4 hole departments of bolt at the U-shaped ring body 1U type mouth of hanging, the interior bolt 4 that leads to of sleeve 2, sleeve 2 external cover has the upper portion connecting piece in using, there is the flange at the both ends of sleeve 2, the upper portion connecting piece can only be in the flange internalization, prevent that the connecting piece from to the extrusion of both sides, the length of sleeve 2 equals the width of U type mouth on the U-shaped ring body 1, the flange also can prevent that the both sides of U-shaped ring body 1 from inwards extrudeing and warping because bolt 4 is too pretension.

The pressure sleeve 3 includes: grind and press cover 5, connector 6 and support and press ring 7, grind and press cover 5 cover in the bending department of U type string ring body 1, grind the shape of pressing cover 5 and be the U type sleeve pipe, grind and press cover 5 lower surface to have a breach, and the breach size is half of the semicircle tube part that grinds and press cover 5, owing to there is the breach here for can follow the follow when grinding and pressing the installation of cover 5 and down embolia, and do not influence inboard contact surface. The transition position of the connecting surface of the hanging ring and the bolt 4 of the existing U-shaped hanging ring is an inclined surface 8, a pressing ring 7 is sleeved on the inclined surface 8 at the middle upper part of the U-shaped hanging ring body 1, the inner annular surface of the pressing ring 7 is also the inclined surface 8 correspondingly matched and contacted, the pressing ring 7 is limited and cannot move downwards when leaning on the upper inclined surface 8 from top to bottom, when downward pulling force is applied, the inclined surface 8 can be continuously extruded, two sides of the pressing ring 7 are respectively provided with one, a connecting body 6 is arranged between the grinding pressing sleeve 5 and the pressing ring 7, the connecting body 6 can be a solid block, but the requirement on matching precision is higher, the connecting body 6 is preferably a spring and can be adapted to change, otherwise, the connecting piece of the U-shaped hanging ring can only apply force on the connecting body 6 without touching the hanging ring, when the connecting piece is sleeved in the U-shaped hanging ring and provides the pulling force downwards, the connecting piece presses the grinding pressing sleeve 5 downwards, the spring connected with the grinding pressing sleeve 5 is in a tensioned state, the pressing ring 7 is pulled downwards, the pressing ring 7 leans against the inclined plane 8 at the middle upper part of the U-shaped ring hanging body 1, downward pulling force is converted into normal force perpendicular to the inclined plane 8, the normal force has component force in the horizontal direction, inward pressing force is generated on the hanging ring, and the pressing force and the sleeve 2 in the ring are pressed against each other, so that part of downward pulling force generated by the bottom connecting piece can be shared. The bottom connecting piece is generally a ball head hanging ring.

The grinding and pressing sleeve 5 is mainly easily worn by mutual rotation of the bottom connecting piece, the grinding and pressing sleeve 5 is preferably made of wear-resistant steel and can be made of high manganese steel, and the sleeve 2 is mainly high in pressure, so that the sleeve 2 is made of pressure-resistant steel and can be made of alloy tool steel.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention, which is defined by the appended claims and their equivalents.
