Abstract
The utility model discloses a tension compensator for contact net, in particular to an elastic tension compensator having a flame-proof, insulated and corrosion-resistant casing which is provided with an elastic member and a drag hook. The elastic member is connected with the drag hook in series. An inner supporting pad and an outer supporting pad are fixed on the drag hook for fixing the elastic member. The elastic tension compensator of the utility model has compact structure, convenient handling, fast compensating response, zero lag, long service life of 30 years, safety and reliability without maintenance, and no pollution.
Description
Technical field
The utility model relates to a kind of contact system tension compensating mechanism, especially a kind of Elastic tension compensator.
Background technology
The contact system tension compensating mechanism is usually used in the tension compensating of contact net system or similar applications, also can be used as the test and the monitoring device of quality or power.Contact system tension compensating mechanism commonly used at present has the top formula of bob and fluid pressure type.Weigh down the top formula and be a kind of more complete permanent tension compensator but take up space big, heavy, the cost height; Fluid pressure type easily leaks, and lags behind, the compensation difference in response, thereby reliability is low.
Summary of the invention
In order to overcome the deficiency of existing tension compensating mechanism, the utility model provides a kind of compact conformation, and is easy to loading and unloading, and the compensation response is fast, do not have to lag behind safe and reliable Elastic tension compensator.
The technical scheme that its technical matters that solves the utility model adopts is: a kind of Elastic tension compensator, has the anti-corrosion shell of fire retardant insulating, be provided with elastic component, drag hook in the anti-corrosion shell of fire retardant insulating, elastic component is connected on the drag hook, on drag hook, be fixed with inside and outside supporting pad, in order to fixing elastic component.
Further: described elastic component can be cylindrically coiled spring, disk spring, Rubber Parts or similar elastomeric body.
Further: described elastic component can be connected in series by several elastic component arrays.
The beneficial effects of the utility model are, Elastic tension compensator of the present utility model, and compact conformation, easy to loading and unloading, the compensation response is fast, does not have to lag behind, and long service life can reach 30 years, and is safe and reliable, need not maintenance, and the feature of environmental protection is good, and is pollution-free.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of Elastic tension compensator of the present utility model,
Fig. 2 is the running condition figure of Elastic tension compensator of the present utility model,
Fig. 3 is the structural representation of the drag hook of Elastic tension compensator of the present utility model.
The anti-corrosion shell of 1. fire retardant insulatings among the figure, 2. elastic component, 3. drag hook, 4. in supporting pad, 5. outer supporting pad.
The specific embodiment
As shown in Figure 1, a kind of Elastic tension compensator, has the anti-corrosion shell 1 of fire retardant insulating, be provided with elastic component 2, drag hook 3 in fire retardant insulating the is anti-corrosion shell 1, elastic component 2 is connected on the drag hook 3, is fixed with inside and outside supporting pad 4,5 on drag hook 3, in order to fixing elastic component 2, elastic component 2 can be cylindrically coiled spring, disk spring, Rubber Parts or similar elastomeric body, and elastic component 2 can be connected in series by several elastic component 2 arrays.
During work, as shown in Figure 2, Elastic tension compensator one end is fixed on the anchoring fixed rack by drag hook 3, other end drag hook 3 links to each other with contact wire, during installation, give suitable tension force, when influence of temperature change contact line length according to ambient temperature, this device plays compensating action, to keep certain force of strain.Be shaped on scale on this Elastic tension compensator drag hook 3, as the standard of tolerance, monitoring when being convenient to installation and control and use.
Elastic tension compensator of the present utility model, compact conformation, easy to loading and unloading, the compensation response is fast, does not have to lag behind, and long service life can reach 30 years, and is safe and reliable, need not maintenance, and the feature of environmental protection is good, and is pollution-free.
