Abstract

The utility model relates to an integral hanging string. The utility model is provided with a wire clamp for a catenary and a wire clamp for a contact wire, and the wire clamp for a catenary and the wire clamp for a contact wire are respectively composed of an inverted U-shaped main body of a wire clamp, a U-shaped hanging ring, bolts, and nuts. Each inverted U-shaped main body of a wire clamp and the middle part of each of two side arms of each U-shaped hanging ring are provided with through holes; each inverted U-shaped main body of a wire clamp is positioned between the two side arms of each U-shaped hanging ring; the bolts pass through the through holes and then are matched with the nuts in a screwing manner; two side arms which are arranged at the open end of the wire clamp for a contact wire are correspondingly bent inwards so as to form tooth openings; heart rings are formed by a protective sleeve ring and a pressing connection tube at both ends of a hanging string wire, and the heart rings are sheathed on the U-shaped hanging ring. The utility model has the advantages that the utility model has both integrity and flexibility, different requirements for the hanging string wire can be adapted to under different working conditions, and the U-shaped wire clamps have simple structure, light weight, and easy shaping.

Description

Dropper

The utility model relates to a kind of dropper.

Existing dropper generally is made up of three parts, the contact wire hanger ear, and catenary hanger ear and dropper line, the three is linked to be an integral body by crimping, and is non-dismountable, can't independently use.Make twisted wire vertical immutable with the angle between wire clamp crimp segment axis and contact wire or the catenary axis, when twisted wire two ends crimp segment axis during not at straight line, form knuckle and focal point of stress in the junction with crimp segment twisted wire not, lose the aggregate breaking force of twisted wire.Promptly be that existing adjustable dropper adopts radial type to connect at the load bitter end, but still there is this problem in the connection of contact line end.Hanger ear in the existing in addition dropper is that two-piece type is formed, and complex structure, weight are big, and technology difficulty is big.

The purpose of this utility model is to design a kind of dropper, both had globality, has alerting ability again, can adapt to of the different requirements of different operating condition to the dropper line, and be connected for right-angled crossing formula hinge between dropper line and the hanger ear, can not make the bending of dropper line produce additional flexure stress and focal point of stress because of the variation of service conditions, the hanger ear first order buckling is shaped in addition, and is simple in structure, in light weight, be shaped easily.

Design plan of the present utility model: a kind of dropper, comprise contact wire hanger ear (1), catenary hanger ear (2) and dropper line (5), contact wire hanger ear (1) and catenary hanger ear (2) are by inverted U wire clip body (7), U type suspension ring (8) and bolt (9), nut (10) constitutes, inverted U wire clip body (7) two side arms middle part correspondence is shaped on through hole (11), U type suspension ring (8) two side arms middle part correspondence is shaped on the through hole (12) that diameter equates with through hole (11), and the cross section of the semicircular arc at U type suspension ring (8) top also is a circular arc, the inboard external recess of protruding, inverted U wire clip body (7) is positioned between the two side arms of U type suspension ring (8), and bolt (9) passes to revolve behind through hole (11) and (12) is furnished with nut (10); Contact wire hanger ear (1) inverted U wire clip body (7) open end two side arms correspondence curves inwardly and forms the age of a draught animal (13) in addition, and suspension ring (8) are the inverted U structure, and the suspension ring (8) on the catenary hanger ear (2) are positive U type structure; The bending two ends of dropper line (5) becomes a capel, and its inboard is set with sheath ring (3), and the end is crimped on dropper line (5) by aluminium hydraulic pressed connecting pipe (4), and capel is sleeved on the U type suspension ring (8), forms not flow-guiding type dropper.

Two ends at dropper line (5) is fixed with conducting terminal (6) again, and is shaped on the through hole (14) identical with through hole (11) diameter on the conducting terminal (6), is sleeved on the inboard bolt (9) of nut (10) by through hole (14), forms the flow-guiding type dropper.

The utility model compared with prior art has the following advantages and effect:

(1) U type hanger ear is simple in structure, in light weight, shaping is easy.

(2) crimping of dropper line and hanger ear do not have direct relation, can independently carry out, and crimp quality can not produce chain reaction to the main body hanger ear of dropper.

(3) only need to change the annex clamper tube of dropper and the specification of capel, can adopt same hanger ear and adapt to the dropper line of different cross section.

(4) be connected for right-angled crossing formula hinge between dropper line and the hanger ear, can be freely formed different angles between dropper bobbin thread and the hanger ear vertical axis, can be because of the variation of service conditions, make the bending of dropper line, produce additional flexure stress and focal point of stress, thereby improve the fail in tension loading of dropper.

(5) turning joint that forms between capel and the suspension ring makes contact wire hanger ear up-down vibration freely, and the dropper line does not need to bend at vibration processes, has improved the force-bearing situation of dropper line, and the elasticity of dropper.

In conjunction with Fig. 1,2,5,6 first kind of embodiment of the present utility model described.

A kind of dropper, comprise contact wire hanger ear (1), catenary hanger ear (2) and dropper line (5), contact wire hanger ear (1) and catenary hanger ear (2) are by inverted U wire clip body (7), U type suspension ring (8) and bolt (9), nut (10) constitutes, inverted U wire clip body (7) two side arms middle part correspondence is shaped on through hole (11), U type suspension ring (8) two side arms middle part correspondence is shaped on the through hole (12) that diameter equates with through hole (11), and the cross section of the semicircular arc at U type suspension ring (8) top also is a circular arc, the inboard external recess of protruding, inverted U wire clip body (7) is positioned between the two side arms of U type suspension ring (8), and bolt (9) passes to revolve behind through hole (11) and (12) is furnished with nut (10); Contact wire hanger ear (1) inverted U wire clip body (7) open end two side arms correspondence curves inwardly and forms the age of a draught animal (13) in addition, and suspension ring (8) are the inverted U structure, and the suspension ring (8) on the catenary hanger ear (2) are positive U type structure; The bending two ends of dropper line (5) becomes a capel, and its inboard is set with sheath ring (3), and the end is crimped on dropper line (5) by aluminium hydraulic pressed connecting pipe (4), and capel is sleeved on the U type suspension ring (8), forms not flow-guiding type dropper.Catenary passes the bottom of catenary hanger ear inverted U wire clip body during use, and contact wire got final product its clamping by the age of a draught animal of contact wire hanger ear inverted U wire clip body bottom.
