Embodiment
Fig. 2 is that the utility model contact net upkeep operation car pilot system embodiment that topples is used view; Fig. 3 is the vertical view of Fig. 2; Fig. 4 is the structural representation of the section of track in Fig. 2.Please refer to Fig. 2-4, the present embodiment provides a kind of contact net upkeep operation car pilot system of toppling, and comprising: at least one group of section of track 2, connection cord 3, first sensor 41 and at least two the second sensors 42.At least one group of section of track 2 is for supporting contact net upkeep operation car 1 to be detected; Each section of track 2 comprises the first track 21 parallel to each other and the second track 22, and the second track 22 is higher than the first track; One end of connection cord 3 is for being fixedly attached to the sway brace 12 of contact net upkeep operation car 1, and the other end of connection cord 3 is fixedly connected with the metope on ground or test ground; First sensor 41 is arranged on connection cord 3, for measuring the pulling force on connection cord 3; At least one second sensor is fixedly installed on respectively on the second track in each section of track, for the wheel of measuring described contact net upkeep operation car to the pressure to track.
Particularly, the section of track 2 can be many groups, its concrete quantity can be determined quantity according to the wheel of contact net upkeep operation car to be detected 1 car body below, preferably, can each take turns can corresponding one group of section of track 2, and the distance that the distance in every group of section of track 2 between the first track 21 and the second track 22 can and be taken turns between two right wheels matches, to support the car body of contact net upkeep operation car 1 by the section of track 2 and right the contacting of wheel.Wherein, the difference in height between the second track 22 and the first track 21 can be determined according to the Railway Environment middle orbit maximum height difference of contact net upkeep operation car 1 required operation; For example, for two situations that track maximum height difference is 180mm in existing rail, comparable the first track 21 of the second track 22 exceeds 180mm.
Alternatively, the section of track 2 can also comprise a base 20, and base 20 tops are that a 201Yu ground, 201， inclined-plane, inclined-plane forms the first angle α, the first track 21 and the second track 22 are fixedly installed on respectively on inclined-plane 201, and the bearing of trend of the first track 21 and the second track 22 is all parallel to ground; Wherein, the value of the first angle α can be determined according to the difference in height between required the first track 21 and the second track 22; Between the first track 21 and/or the second track 22 and inclined-plane, be provided with the second sensor 22.That is, can be between the second track 22 and inclined-plane 201 and the first track 21 and inclined-plane between, the position of right each wheel of corresponding wheel is fixedly installed respectively the second sensor 42; Also can be only between the second track 22 and inclined-plane 201, the position of the right wheel of corresponding wheel arranges the second sensor 42; Only need after contact net upkeep operation car 1 supports on the section of track 2, can by this second sensor obtain accurately and rapidly wheel to and the second track 22 between force value.
Before contact net upkeep operation car comes into operation, can utilize the contact net upkeep operation car that the present embodiment provides to topple pilot system to its test of toppling.Detailed process can be:
S11, contact net upkeep operation car 1 is placed on the section of track 2, and the other end of connection cord 3 is fixedly attached on the sway brace 12 at contact net upkeep operation car 1 top, and make connection cord 3 simultaneously perpendicular to the bearing of trend of sway brace 12 and car body as far as possible.
S12, adjust the position of suspension bucket 12, suspension bucket 12 stretched out towards a side that deviates from the second track 22, and make suspension bucket stretch out direction simultaneously perpendicular to bearing of trend and the sway brace 12 of contact net upkeep operation car car body.
S13, on connection cord 3, apply power, so that the numerical value of first sensor 41 reaches the first preset value, whether the judgement now numerical value of the second sensor 42 is zero.
If now the second sensor 42 numerical value are non-vanishing, show that wheel, to not departing from the second track 22, can not topple; For example, if the second sensor 42 numerical value are zero or (can are a scope: 0～5N), show that a wheel of taking turns centering has departed from the second corresponding track, car body will soon topple close to zero.Whether the resistance to capsizing that can judge this contact net upkeep operation car according to the test findings of toppling is up to standard, accordingly structure is improved, comes into operation after to be targeted again.
It should be noted that, connection cord is mainly used in simulating the maximum force that may be subject to when sway brace 12 is stirred the electric wire of contact net, that is, required the first preset value reaching of first sensor 41 can be determined according to the maximum force that this sway brace 12 may be subject in follow-up use procedure; Certainly in addition, connection cord 3 can also be simulated the effect of other power simultaneously, for example crosswind also can be scaled the second preset value to the impact of car body, and on connection cord 3 increase power so that the numerical value of first sensor 41 reaches the first preset value and the second preset value sum; Can further improve like this reliability of test.
The contact net upkeep operation car that the present embodiment the provides pilot system of toppling, can be to the test of toppling of contact net upkeep operation car, with the antidumping performance of test contact net upkeep operation car, whether can meet the requirement of its environment that need move, avoided, in the follow-up process that comes into operation, capsizing case occurs, avoid economic loss, also improved the security in contact net upkeep operation vehicle overhauling operation process.
Further, the above-mentioned contact net upkeep operation car pilot system of toppling can also comprise:
Further, this contact net upkeep operation car pilot system of toppling can also comprise:
Be fixedly installed on ground column 302, column 302 arrives between the section of track 2 at connection cord 3 and junction, ground, preferably, column 302 to the line between supporting walls 12 also can be simultaneously perpendicular to the bearing of trend of contact net upkeep operation car car body, maximum to guarantee the moment that the acting force of 3 pairs of car bodies of connection cord produces; On column 302, be also provided with for changing the fixed pulley 303 of the bearing of trend of connection cord 3, by adjusting the height of this column 302, can adjust easily connection cord 3 with respect to the angle of sway brace 12,, height by column can be adjusted in the plane perpendicular to car body bearing of trend, the angle of connection cord 3 and 12 one-tenth of sway braces, thereby can more conveniently rapidly line rope 3 be adjusted to the state perpendicular to supporting walls 12, further facilitate test operation.
Finally it should be noted that: each embodiment, only in order to the technical solution of the utility model to be described, is not intended to limit above; Although the utility model is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
