Abstract
The utility model discloses a kind of spring compensator indicating device is installed, for electrification railway contact net tension compensating system.Indicating device comprises indicating device body and indicating device body is arranged on to the erecting device on spring compensator, indicates respectively temperature and compensating length on indicating device body, and both are corresponding one by one.The indicating device that the utility model provides has simple in structure, with low cost, high reliability, and the workman of energy guide field carries out simple and effective operation, ensures the safe and reliable operation of spring compensator.
Description
Technical field
The utility model relates to a kind of indicating device, relates in particular to a kind of spring compensator indicating device is installed, for electrification railway contact net tension compensating system.
Background technology
Conventionally built on stilts catenary and contact wire or the cable state in tensioning all the time in the contact net for power supplying of electrified railway, to ensure the normal work of contact net for power supplying.Cause that because catenary, contact wire or cable are subject to variation of ambient temperature its effect of expanding with heat and contract with cold causes length to change, the pulling force that causes catenary, contact wire or cable to bear is unstable.Therefore, in existing contact net for power supplying, used widely the spring compensator of catenary or contact wire.But, in existing contact system circuit, while adopting a kind of spring tension compensating device, usually because the inaccurate skew that causes center-point is controlled in the installation site of spring compensator, make fitting operation inconvenience, if pull out longly, easily cause when the coldest compensating device rope stretching to the limit, cause compensating device to occur hard draw and cause compensation to lose efficacy; If pull out too shortly, easily cause compensating device rope closing when the hottest to the limit, to cause compensating device to occur not drawing and causing compensation to lose efficacy.Once compensation was lost efficacy, and just can cause the accident between pantograph on railway.So, when installation, have a kind of installation instruction will become important.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model is to provide the device using when a kind of cable catenary of the supply network for electrified railway or contact wire spring compensator are installed.
For achieving the above object, the utility model provides a kind of spring compensator that indicating device is installed, and comprises indicating device body and indicating device body is arranged on to the erecting device on spring compensator, indicates respectively temperature and compensating length on indicating device body.
Further, erecting device is the mounting base being arranged on spring compensator.
Further, mounting base is with bindiny mechanism.
Further, indicating device body is parallel to the pull-out direction of spring compensator.
Further, indicating device body is lath-shaped cuboid.
Further, temperature is corresponding one by one with compensating length.
In described indicating device, temperature and compensating length corresponding relation are: suppose that cable length is L, its thermal expansion coefficient is made as β, actual cable operation minimum temperature T
l, actual cable operation highest temperature T
h, the actual complementary range of the maximum of compensating device is L
1=L × β × (T
h-T
l).If the actual cable running temperature while installation is T
a, the pull-out of the compensating device of our reality distance should be just so: L
a=L × β × (T
a-T
l).
The utlity model has simple in structure, with low cost, high reliability, workman that can guide field carries out simple and effective operation, ensures the safe and reliable operation of spring compensator.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, so that those skilled in the art understands the purpose of this utility model, feature and effect fully.
Brief description of the drawings
Fig. 1 is the schematic diagram that the spring compensator of a preferred embodiment of the present utility model is installed indicating device.
Detailed description of the invention
The utility model is that a kind of spring compensator is installed indicating device.
Fig. 1 is the embodiment that this spring compensator is installed indicating device.As shown in Figure 1, spring compensator is installed indicating device 1, comprises indicating device body 2 and the mounting base 3 that is positioned at indicating device body 2 one end, indicates respectively temperature 4 and compensating length 5 on indicating device body 2, and the two is corresponding one by one.Mounting base 3 is fixed on spring compensator 6 for spring compensator being installed to indicating device 1.
Indicating device body 2 is lath-shaped cuboid, when mounting spring compensating device 6, first spring compensator being installed to indicating device 1 is fixed on spring compensator 6 by the bindiny mechanism on mounting base 3, operating personal is measured after actual ambient temperature, with spring compensator, indicating device 1 being installed combines, spring compensator 6 is pulled out to end and move the compensating length corresponding with temperature 45 positions fixing to, by cable catenary or contact wire 7 tensionings, and be connected with the pull-out end of spring compensator 6.
When verification spring compensator 6, operating personal is measured after actual environment temperature, as the actual position of finding the pull-out end of spring compensator 6 has departed from the position that spring compensator is installed the corresponding compensating length 5 of temperature 4 on indicating device 1,, by regulating the pull-out end position of described spring compensator 6, make itself and spring compensator that compensating length 5 position consistency corresponding to temperature 4 on indicating device 1 are installed.
More than describe preferred embodiment of the present utility model in detail.Should be appreciated that those of ordinary skill in the art just can make many modifications and variations according to design of the present utility model without creative work.Therefore, all technical personnels are in the art complied with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be in by the determined protection domain of claims.
Claims (5)
1. a spring compensator is installed indicating device, it is characterized in that, comprise indicating device body and described indicating device body is arranged on to the erecting device on described spring compensator, on described indicating device body, indicate respectively temperature and compensating length, described temperature is corresponding one by one with described compensating length.
