Abstract
An automatic elastic tension compensator for the contactor of electric collector is composed of left and right external suporting pads, left pull hook passing through left external supporting pad and fixed to right one, right pull hook passing through right external supporting pad and fixed to left one, at least two serial springs on said left and right pull hooks, and internal supporting pad between said springs. Its advantage is high tension-compensating precision.
Description
Affiliated technical field
The present invention relates to a kind of Elastic tension compensator, especially a kind of Contact Net Elasticity Tension Compensator that is applied to railway, subway and urban light rail.
Background technology
Elastic tension compensator is mainly used in railway, subway and urban light rail, mainly to because the telescopic that causes that expands with heat and contract with cold compensates, reduces vibration, keeps the effect of balance.Usually the Elastic tension compensator that adopts mainly contains Elastic tension compensator, fluid pressure type automatic compensator, bob stone roller formula compensator and the butterfly spring compensator of single spring.But all there is certain deficiency in above-mentioned compensator: the Elastic tension compensator compensation rate of single spring is little, and Applicable scope is little; The fluid pressure type automatic compensator is easy to generate seepage, lags behind thereby produce compensation; It is comparatively heavy to weigh down stone roller formula compensator, and take up room big, expense is high; Butterfly spring compensator compensation rate is little, and compensation rate is measured inaccurate.
Summary of the invention
The invention provides a kind of many series connected compensators of spring that adopt based on cylindrically coiled spring in upright arrangement.
The technical scheme that realizes the object of the invention is: a kind of elasticity tension automatic compensator for contact net, comprise Zola's hook, right drag hook, the outer supporting pad in a left side, right outer supporting pad, spring, the supporting pad bending place is provided with back-up block outside the supporting pad and the right side outside a left side, Zola's hook passes the outer supporting pad in a left side captives joint with right outer supporting pad, right drag hook passes right outer supporting pad captives joint with the outer supporting pad in a left side, Zola's hook and the orthogonal installation of right drag hook, outside a left side supporting pad and right outside between the supporting pad Zola's hook and right drag hook on be set with spring, in the spring arranged outside outer cover is arranged, the outer cover two ends respectively with a left side outside supporting pad captive joint with right outer supporting pad, this compensator is provided with two springs at least, spring is installed in series, be provided with interior supporting pad between adjacent springs, interior supporting pad and Zola's hook and right drag hook suit flexibly connect.
Install for convenience and monitoring, further: outside a left side, be set with scale on the supporting pad outside the supporting pad or the right side.
In order to make spring have the favorable mechanical performance, further: the spring material adopts the chrome-silicon spring steel.
In order to make compensator have higher mechanical strength and corrosion-resistant property, further: Zola's hook, right drag hook, the outer supporting pad in a left side, right outer supporting pad and interior supporting pad adopt austenitic stainless steel.
Elasticity tension automatic compensator for contact net of the present invention, takes up room for a short time in light weight, compact conformation, and the contact line length scope that is suitable for is wide, tension stability, variation range is little, tension compensating precision height, the temperature range that conforms is wide, install and monitoring convenient.

The specific embodiment
The invention will be further described below in conjunction with accompanying drawing and embodiment.
Elasticity tension automatic compensator for contact net as shown in Figure 1, comprise Zola's hook 1, right drag hook 2, the outer supporting pad 3 in a left side, right outer supporting pad 4, influence freely stretching of spring 5 in order to make the unlikely distortion of compensator drag hook when stressed, supporting pad 4 bending places are provided with back-up block 9 outside the supporting pad 3 and the right side outside a left side, Zola's hook 1 passes the outer supporting pad 3 in a left side captives joint with right outer supporting pad 4, right drag hook 2 passes right outer supporting pad 4 captives joint with the outer supporting pad 3 in a left side, Zola's hook 1 and right drag hook 2 orthogonal installations, be set with at least two springs 5 on Zola's hook 1 outside a left side between supporting pad 3 and the right outer supporting pad 4 and the right drag hook 2, spring 5 is installed in series, supporting pad 7 between adjacent springs 5, being provided with, interior supporting pad 7 flexibly connects with Zola's hook 1 and right drag hook 2 suits, in spring 5 arranged outside outer cover 6 is arranged, outer cover 6 two ends respectively with a left side outside supporting pad 3 captive joint with right outer supporting pad 4.Install for convenience and monitoring, outside a left side, be set with scale on the supporting pad outside the supporting pad or the right side.Aspect material: the spring material adopts the chrome-silicon spring wire; Zola's hook, right drag hook, the outer supporting pad in a left side, right outer supporting pad and interior supporting pad adopt austenitic stainless steel.
Elasticity tension automatic compensator for contact net of the present invention, in light weight, simple in structure, it is little to take up room, and reaches 15～20 years service life; Can adopt the spring series connection of varying number, to adapt to different contact line lengths, single, double contact line length range of use 50～300mm according to field requirement.With a kind of rated tension, can adopt the spring series connection of varying number, form series of products, adapt to different contact line lengths; Two contact wire compensator tension force can reach 26KN, and single contact wire tension force can reach 14KN, and tension stability, and variation range is little, tension compensating precision ± 5%, or the temperature range that conforms-40 ℃～+ 50 ℃.
