Abstract
A contact net adjustable non-carrier unitary stainless steel hanging string comprises a stainless steel hanging string rope, and a load-bearing grommet sleeve and a contact wire clip connected with the upper end and the lower end of the hanging string rope, wherein, the load-bearing grommet sleeve is of an n-shaped structure and is clamped on an n-shaped nylon lining; the lower part of the n-shaped load-bearing grommet sleeve is provided with a stressed bolt; the hanging string rope is hung on the stressed bolt. The utility model is characterized in that: the hanging part of the hanging string rope is wrapped with a string body hoop clip which clamps the hanging part by the two pieces of the clip; both sides of the upper part of the string body hoop clip are respectively provided with string rope pin stops, while the middle part of the string body hoop clip is provided with a clamping bolt; the root of the clamping bolt is provided with a despinning face. The utility model has the advantages that the hanging string has a simple and beautiful overall structure and is convenient for installation and adjustment; in order to adjust the length of the hanging string, a user only needs to screw off the clamping bolt and tighten or loosen a wire cable; moreover, the hanging string rope is a flexible stainless steel wire cable which has high intensity and good flexibility and solves the problem that the prior rigid string rope is easy to break; in addition, the product is corrosion resistant, nonconducting and safe and reliable in operation and has extensive use in chain type hung contact net of electrified railway.
Description
(1) technical field
The utility model relates to a kind of whole corrosion-resistant steel dropper of the adjustable non-current-carrying of contact system that is applicable to electrified railway.
(2) background technology
The link dropper that contact nets in electrified railways use at present is hand-made with Φ 4.0 galvanized iron wires, and its advantage is with low cost, but has following shortcoming: a, easily gets rusty, and disconnected the coming off of dropper rust often occur and causes accident between pantograph.B, its upper and lower end are fixed in catenary and the contact wire with wire clamp respectively, because the thermal expansion coefficient of catenary (mostly being steel) and contact wire is different, when variation of ambient temperature, dropper meeting inclination and offset, cause contact wire highly to change, influence pantograph and steadily flowed, particularly will worsen pantograph contact line relation during the electric locomotive high-speed cruising, produce a large amount of electric arcs, burn lead and pantograph.C, dropper carry certain electric current, dropper can be blown when particularly contact system is unusual to cause the accident.D, complicated, the adjustment difficulty of installation.E, for being made by handwork, profile is different, lacks aesthetic feeling.
(3) summary of the invention
The purpose of this utility model is just at existing weak point in the above-mentioned prior art and newly-designed a kind of corrosion-resistant steel dropper, and this dropper is rational in infrastructure, and good looking appearance is installed, easy to adjust.
The purpose of this utility model realizes by following scheme: the whole corrosion-resistant steel dropper of the adjustable non-current-carrying of this contact system comprises corrosion-resistant steel dropper rope and connects thereon, the catenary ring set at following two ends and contact wire wire clamp, the catenary ring set is a ∩ shape structure, be installed on the ∩ shape nyliner, ∩ shape catenary ring set bottom is coated with stressed bolt, corrosion-resistant steel dropper rope is mounted on this stressed bolt, wherein: the position that mounts at corrosion-resistant steel dropper rope is surrounded by a chord body cover card with two to the folder mode, both sides, chord body cover card top are respectively equipped with string rope tommy, its middle part is provided with fastening bolt, the root of fastening bolt is processed with only radial facing, and the shape of chord body cover card upper bolt hole is consistent with fastening bolt root section shape.
In the utility model, the chord body cover card is formed by forward and backward two, and on a slice claw is arranged therein; End at stressed bolt is provided with locking pin, is used to prevent screw cap-falling; Bending place later between corrosion-resistant steel dropper rope lower end and the contact wire wire clamp is provided with a corrosion-resistant steel chip saddle, can avoid the steel cable bending place to damage because of the vibrations friction, has improved the force-bearing situation of dropper rope.The shape of the root section shape of fastening bolt and the chord body cover card upper bolt hole that matches with it is rectangular configuration, also can be triangle, hexagon or circle and lacks the shape structure, its objective is to prevent to rotate mutually between the two.
Contact wire spare folder in this dropper adopts the existing universal product, and other metal piece all is a stainless steel parts.
The utility model is owing to adopted above-mentioned design, promptly be equipped with chord body cover card and fastening bolt, can avoid steel rope in regulating clamping process, to be blocked the disconnected problem of wound or rope strand card, and clamp firmly, integral structure is simple, attractive in appearance, installation, easy to adjust, when needs are adjusted dropper length, only need unclamp fastening bolt, take out tight or loosen steel cable to get final product, because the root of fastening bolt is a rectangular configuration, in chord body cover card bolt hole, can not rotate, therefore can a hand adjustment save rope length, the another hand turns nut, and it is very convenient quick to adjust rope length.The dropper rope adopts Φ 3.2 soft stainless steel cables, and intensity height, elasticity are good, can avoid the defective of existing steel string rope frangibility.This product withstanding corrosion, non-conductive, safe and reliable to operation, can be widely used in the contact system of electric railway chain type hanging, be the novel contact system parts that substitute original dropper.
