Abstract
This utility model discloses a limit device of a locator for electrified railway contact network, which comprises a body, wherein one end of the body is provided with a limit ring; the other end thereof is provided with a fixing device; when the device disclosed by this utility model is used, the fixing device is fixed on a locating pipe; the limit ring is sleeved on the locator; or the fixing device is fixed on the locator; and the limit ring is sleeved on the locating pipe. According to the device disclosed by this utility model, the up-down and left-right movement of the locator can be limited effectively; furthermore, the device disclosed by this utility model effectively prevents the locator from being drooped and arched when a contact line is broken.
Description
Technical field
The utility model relates to a kind of electrifing railway contacting net system element, relates in particular to a kind of contact nets in electrified railways and uses the steady arm inhibiting device.
Background technology
The pantograph of electric locomotive is normally got when stream through overhead contact line, and pantograph applies lifting power upwards to contact wire all the time, makes between pantograph and contact wire and reliably contact the assurance current carrying quality.The lifting power that pantograph applies is raised contact wire simultaneously, and steady arm is also raised thereupon.Train high-speed cruising or when the curve location receives the influence of aerodynamic force, pantograph inertia, superelevation of outer rail etc., and the lifting amount of steady arm is easy to surpass specified value, and collision steady arm or registration arm produce pantograph and catenary fault.Therefore, restrictor lifting amount can reduce the probability that pantograph and catenary fault takes place.
In the practical application, there are various bad weather conditions such as dust storm, sleet along the line in railway, and under wind effect, contact wire occurs jumping double swerve up and down; During icing, contact wire is sagging etc.The motion of contact wire directly influences the motion of steady arm, makes steady arm be in off-normal positions such as sagging, skew easily, influences parameters such as contact system stagger, windage yaw, electric locomotive through the time be prone to take place pantograph and catenary fault.Therefore, restrictor left and right sides deflection, saggingly also can guarantee further that electric locomotive normally moves.
Registration device is the fixing device of contact wire position in electrifing railway contacting net system cantilever structure and the headspan suspension structure, generally supports (or the registration arm messenger wire adds the location pipe clamp) etc. by steady ear, steady arm, positioning support, registration arm, steady ring and registration arm and forms.Be divided into spacing registration device and non-spacing registration device, spacing registration device is generally at the positioning support middle part and establishes a registration mast, and steady arm body tail end adopts spacing location hook.
Registration device of the prior art is the lifting of restrictor to a certain extent, but about can't limiting and move down.
The utility model content
The purpose of the utility model provide a kind of effectively restrictor about, sway, can prevent that the more sagging contact nets in electrified railways of making bow of contact wire when broken string steady arm from using the steady arm inhibiting device.
The purpose of the utility model realizes through following technical scheme:
The contact nets in electrified railways of the utility model are used the steady arm inhibiting device, comprise body, and an end of said body is provided with spacing ring, and the other end is provided with anchor fitting;
Said anchor fitting is fixed on the registration arm, and said spacing ring is enclosed within on the said steady arm; Perhaps, said anchor fitting is fixed on the said steady arm, and said spacing ring is enclosed within on the registration arm.
Technical scheme by above-mentioned the utility model provides can find out that the described contact nets in electrified railways of the utility model are used the steady arm inhibiting device, because an end of body is provided with spacing ring, the other end is provided with anchor fitting.During use, anchor fitting is fixed on the registration arm, and spacing ring is enclosed within on the steady arm; Perhaps, anchor fitting is fixed on the steady arm, and spacing ring is enclosed within on the registration arm.Effectively restrictor about, sway, more can prevent the sagging bow of beating of contact wire when broken string steady arm.

Among the figure: 1, inhibiting device body; 2, anchor fitting; 3, spacing ring; 4, steady arm; 5, registration arm.
The specific embodiment
The contact nets in electrified railways of the utility model are used the steady arm inhibiting device, the specific embodiment that it is preferable such as Fig. 1, shown in Figure 2:
During concrete the application, like Fig. 1, shown in Figure 2, said anchor fitting 2 can be fixed on the registration arm 5, and said spacing ring 3 is enclosed within on the said steady arm 4; Perhaps, said anchor fitting 2 is fixed on the said steady arm 4, and said spacing ring set 3 is on registration arm 5.
Said anchor fitting 2 can comprise U bolt or major-minor anchor ear etc.
Said spacing ring can be circular port, elliptical aperture or strip hole etc.
The utility model effectively restrictor about, sway, more can prevent the sagging bow of beating of contact wire when broken string steady arm.
Below in conjunction with the accompanying drawing and the specific embodiment the utility model locate mode and two kinds of schemes thereof are elaborated.
First kind of scheme; Referring to Fig. 1, during installation steady arm is inserted in spacing ring, after device to be positioned is adjusted to the right place; This spacing registration device is anchored on the registration arm through modes such as U bolt or major-minor anchor ear modes; This spacing registration device with the synchronous deflection of registration arm, move, and the moving range through the spacing ring restrictor, the size of spacing ring allows deviation angle definite according to installation site and steady arm on the steady arm gradient, the registration arm along circuit.
Second kind of scheme; Referring to Fig. 2, after device to be positioned is adjusted to the right place, the spacing ring of this spacing registration device is placed on the registration arm; And adopt modes such as U bolt, anchor ear that this spacing registration device is anchored on rectangle or the circular steady arm; This spacing registration device moves with steady arm, and comes the restrictor moving range through the gap between spacing ring and registration arm, and the size of spacing ring allows deviation angle to confirm according to installation site and steady arm on the steady arm gradient, the steady arm along circuit.
Fig. 3 is seen in the installation site of the utility model.
The above; Be merely the preferable specific embodiment of the utility model; But the protection domain of the utility model is not limited thereto; Any technical personnel of being familiar with the present technique field is in the technical scope that the utility model discloses, and the variation that can expect easily or replacement all should be encompassed within the protection domain of the utility model.
