Abstract
Disclosed is an adjustable integral wire suspending device relating to the electric power supply facilities technical field of the electrified railway. The adjustable integral wire suspending device comprises two messenger wires, and one end of each messenger wire is connected to a two-piece type cable clamp respectively; the other ends of the two messenger wires depend on each other side by side, and the end heads are fixedly connected to each other by hoops. The neck-and-neck segment of the two messenger wires is provided with a barrel shaped control agent which is provided with regulating screws. A pressing pad is arranged between the regulating screw and the messenger wires. The adjustable integral wire suspending device is used for hanging electrical contact wires. Compared with the prior art, the utility model chiefly solves the problems of the loose strand of the messenger wires, multi-species of the cable clamps and the weak interchangeability and applicability in the prior art. Furthermore, the adjustable integral wire suspending device also has the advantages that the installation and maintenance is convenient, easy and time-saving.
Description
Technical field
The utility model relates to electrified railway power supply facility technical field, especially a kind of device that is used to hang the electric power contact wire.
Background technology
Electric railway mainly is made up of electric locomotive and traction power set, and traction power set generally is divided into traction substation and contact system two parts.The function of contact system is the direct contact by it and block of bow collector of electric locomotive, and electric energy is passed to electric locomotive.The structure that contact system extensively adopts at present is the overhead type contact system.In the contact system of overhead contact line with catenary, contact wire is suspended on the catenary by dropper, and dropper can be divided into fixed type dropper and adjustable dropper again.Adjustable dropper can be regulated the length of dropper, guarantee that by the length of regulating dropper contact wire is apart from the height of rail level and the system height of contact suspension, improve the elasticity of contact suspension, adjust the degree of speeding of contact wire, guarantee contact wire and the good swiping of pantograph, improve block of bow collector of electric locomotive and get current mass.At present, known adjustable dropper is the adjustable dropper of TJ95+CT85 type that is adopted on China's Beijing-Zhengzhou line.The dropper of this structure, its dropper line has a multiply conductor wire, one end of this line connects the two-piece type wire clamp of contact wire, the other end is connected with Wiring nose, this end is walked around and is fixed on after Horizontal messenger wire clamp turns back on the bolt of Horizontal messenger wire clamp, and its section of turning back is provided with one and adjusts the length bolt clamp.This dropper when mounted, the dropper line of the residue length back that can only doubling be intertwined is fixed with bolt clamp with adjustment length, in use, broken lot very easily takes place through repeatedly vibrating in the loose part of bending, when the dropper line behind the generation broken lot is regulated length again, be difficult to accurate adjustment; In addition, its Horizontal messenger wire clamp of the dropper of this structure and contact wire wire clamp are not general, be used for the catenary that the wire clamp of clamping catenary can only the certain thickness of clamping, can not the clamping contact wire or the catenary of other specification, and its opening degree of depth of wire clamp that is used for clamping contact wire one end is little, can only the clamping contact wire, and can not the clamping catenary, commonality is not strong, is not easy to I﹠M.
Summary of the invention
The purpose of this utility model provides a kind of adjustable dropper device, and problem and member kind that it mainly can solve dropper line broken lot in the prior art are many, the problem that interchangeability is not strong.
In order to address the above problem, the scheme that the utility model adopts is: it includes dropper line and two-piece type wire clamp, and described dropper line has two, and each is connected an end of every dropper line with a described two-piece type wire clamp; The other end of two dropper lines leans on side by side mutually, and is mutually permanently connected by the hoop cover in the end; The outer control agent that is set with tubular of section side by side of described two dropper lines, this control agent is provided with set screw, between described set screw and described dropper line compress gasket is housed.
Can be provided with the profile of tooth striped on the contact surface of above-mentioned control agent and described dropper line and on the contact surface of described compress gasket and described dropper line, prevent that to increase the clamping friction force between control agent and the described dropper line, to rub the dropper line from producing slide relative.Above-mentioned compress gasket may be made in strip, its cross-sectional plane is curved, and it stretches out the outer part of described control agent and outwards bends in the groove of described control agent termination, to guarantee that the set screw roof pressure is on the centre of compress gasket.The folder mouth of above-mentioned two-piece type wire clamp is to the distance H of cable clip bolt hole axial line
1More preferably greater than 22 millimeters, folder mouthful distance H to wire clamp clamping axial line
2Be preferably 76 °～80 ° greater than 6.17 millimeters, its folder bicker β, catenary and contact wire to guarantee that wire clamp can the clamping plurality of specifications can prevent that again wire clamp from use meeting accident deflection and making bow simultaneously.
Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:
1, can effectively prevent dropper line broken lot.Because an end of two dropper lines leans on side by side mutually, and be mutually permanently connected by the hoop cover, therefore do not have the situation of residue line relaxation bending, can effectively prevent dropper line broken lot under the service conditions of frequent vibration in the termination.
2, convenient for installation and maintenance easy.Because two interconnective dropper line institute bonded assembly wire clamp specifications can be made unanimity, make no distinction of rank, and the control agent of tubular are easy to use and reliable, install and regulate more or less freely quick.But the general one-time-reach-place of its installation does not need to adjust again.Through the test contrast, its control duration is saved 30% than the control duration of prior art.Therefore can improve the serviceability of overhead contact line greatly, for operation less, do not have maintenance and create conditions.
3, the wire clamp of catenary and contact wire wire clamp are general, and manufacturing, management are easier to.
