Described guide vane end stop 7 for material be stainless steel.
The technical scheme provided as can be seen from above-mentioned the utility model, a kind of use for electric locomotive earthed switch that the utility model embodiment provides, stroke was there is when can effectively prevent grounding arm from opening, prevent the situation causing grounding arm stuck from occurring, ensure earthed switch closed procedure, improve the reliability of device.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme of the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of the use for electric locomotive earthed switch of prior art;
The structural representation of the use for electric locomotive earthed switch that Fig. 2 provides for the embodiment of the present invention.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on embodiment of the present utility model, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to protection range of the present utility model.
Below in conjunction with accompanying drawing, the embodiment of the present invention is described in further detail.
As shown in Figure 2, a kind of use for electric locomotive earthed switch, structure comprises the first grounding arm 1, second grounding arm 2, mounting panel 6, connecting rod 5 and Manual drive mechanism 8; The first rotating shaft 3 that first grounding arm 1 passes through is hinged with mounting panel 6, and the second rotating shaft 4 that the second grounding arm 2 passes through is hinged with mounting panel 6, connecting rod 5 two ends respectively with the first grounding arm 1 and the second grounding arm 2 hinged; First grounding arm 1, second grounding arm 2, mounting panel 6 form parallelogram sturcutre with connecting rod 5; Manual drive mechanism 8 drives the second rotating shaft 4 rotating opening or closed ground switch; Solid line is earthed switch open mode, and dotted line is earthed switch closure state.Manual drive mechanism 8 is general structure, and handle, tommy bar and runner etc. are all applicable, as operating personnel rotate earthed switch handle, drives the second rotating shaft 4 to rotate by omitting mechanism's such as cam mechanism.
Inventive point of the present utility model is, is provided with the guide vane end stop 7 of restriction first grounding arm 1 at the extreme position of earthed switch open mode between described mounting panel 6 and the first grounding arm 1.Guide vane end stop 7 effectively prevent stroke phenomenon, prevented the operation failure when carrying out earthed switch closed procedure.
Here extreme position namely facilitates earthed switch to close, not stuck position, in this example, the angle that the first described grounding arm 1 is the axial connecting line of the first rotating shaft 3 and the second rotating shaft 4 and the axial connecting line of connecting rod 5 and the first grounding arm 1 and the second grounding arm 2 pin joint at the extreme position of earthed switch open mode is 12 ± 3 °.This angle is usually relevant with the structure of earthed switch, can ensure that earthed switch closes smoothly as long as can change, not stuck.
In this example, described guide vane end stop 7 is located on mounting panel 6.Can be fixed by screw.In addition, described guide vane end stop 7 also can be located on the first grounding arm 1.Can be fixed by screw, also can with the first grounding arm 1 on one.
