Abstract
The invention belongs to the technical field of power supply to electrified railways. As tensions of a carrier cable and a contact wire of a contact network of the electrified railway are changed with changes of ambient temperature, the tensions are required to be compensated. The invention provides an elastic tension compensation device which comprises a movable rhombus (with a changeable inner angle), wherein tension springs are respectively arranged on the same side between the upper end point and the lower end point; a left bracing wire is connected with a right end point, and penetrates through a left end point; a right bracing wire is connected with the left end point and penetrates through the right end point. The elastic tension compensation device overcomes the shortcoming that the travel is in direct proportion to force, thus realizing tension compensation for the carrier cable and the contact wire. The device is simple in structure, convenient to mount and maintain and high in tension compensation precision.
Description
Technical field
The present invention relates to the carrier cable of a kind of compensation electrical railway, contact line, because of variation of ambient temperature,
Cause length to change, and keep the device of constant tension.Belong to electrified railway power supply technical field.
Background technology
In the contact net for power supplying of electric railway, under any weather conditions, built on stilts carrier cable, connect
Tactile line to be in the state normal work with guarantee contact net for power supplying of tensioning all the time, but due to environment temperature
Change, carrier cable, contact line length change, cause tension variation, therefore, prior art
Contact net for power supplying in, use widely, can compensate carrier cable, contact line tension compensating mechanism.
At present, in electrification railway contact net, wide variety of tension compensating mechanism is by fixed pulley and pendant
The compensation device that stone roller is constituted, this compensation has simple in construction, the advantage of tension stability, but there is volume
Greatly, Heavy Weight, unsightly, install and maintenance cost is high, etc. shortcoming.It addition, use cylindrical screw pressure
Contracting spring or other elastic compensating devices, have simple in construction, installs and easy to maintenance, but does not overcome row
Journey is directly proportional to active force (stroke increasing action power also increases), and such compensation device tension force is unstable.
Summary of the invention
It is an object of the invention to: the shortcoming existed for above prior art, propose a kind of elasticity tension
Compensation device, instant invention overcomes stroke and is directly proportional to active force, makes contact net change in environment temperature
In the case of tension force be basically unchanged.
The object of the present invention is achieved like this, a kind of elasticity tension compensation device, it is characterized in that: one
Movable diamond (interior angle can change), the homonymy between upper extreme point and lower extreme point has extension spring, Zola's line respectively
It is connected with right endpoint, and through left end point, right bracing wire is connected with left end point, through right endpoint.Or it is a kind of
Elasticity tension compensation device, is characterized in that: two identical movable diamond (interior angle can change), by public affairs
End points links together altogether, crosses two limits of public point, end points is divided into four sections, respectively constitutes two
Two limits that rhombus is adjacent, the homonymy between same rhombus upper extreme point and lower extreme point has extension spring respectively, left
Bracing wire is connected with right endpoint, and through public point, and through left end point, right bracing wire is connected with left end point,
Through public point, through right endpoint.
Extension spring between described upper extreme point and lower extreme point, it is also possible to be the flexible member identical with extension spring effect.
Described end points can be bolt, it is also possible to be drift bolt, rivet.
Described two identical movable diamond (interior angle can change), are linked together by public point,
Can also be that multiple rhombus links together.
This device has: when environment temperature (higher) is gradually lowered, and carrier cable, contact line length are gradually
Shortening, tension force is not gradually increased, but ascending the most descending；In turn, environment temperature
(relatively low) gradually rises, and carrier cable, contact line length are progressively longer, and tension force is not gradually reduced, and
It is ascending the most descending；This device overcomes stroke and is directly proportional to active force, if this device
Compensating tension force and be set in work near maximum, carrier cable, the tension force of contact line are basically unchanged.This device
Simple in construction, low cost, convenient for installation and maintenance.
