Definitions
- a derail detection device based on the mechanical principle of gravity is known on the buffer rails at each end of a vehicle. It consists of a block connected to the general line of the pneumatic braking system by a pipe of
- connection comprising an emergency valve.
- the air is maintained under pressure in a chamber of the block, the
- the major disadvantage of this device lies in its unreliability, that is to say in the risk of untimely emergency braking, for a double reason.
- a first series of hazards is inherent in the empirical determination of the aforementioned braking engagement threshold and the influence of fluctuating parameters such as pressure variations in the pipe, temperature on
- a threshold for example 5.5 g, may be ideal under given conditions, but not in others. It is further observed that, by definition, the braking is engaged only at the time of the fall of the wheel on the ballast or on a cross. A second series of randomness proceeds from the location of the fixing of the detector block (the buffer-holder elements on which a block is fixed being damped). Indeed, the measurement of a force from a suspended element, while the damping is intended to reduce its intensity and is, moreover, variable, is necessarily uncertain.
- the base of the shoe extends under normal conditions to a constant predetermined distance above the upper plane of the rail and is provided, opposite the rail, a notch of break. During a derailment, the shoe hits the rail and breaks, causing braking of the wheels of all cars, the operating pressure of the braking system falling to atmospheric pressure.
- FR-2,782,688 discloses a detection device also based on this principle, comprising a body fixed to a bogie element and provided with a hollow arm, which extends at a predetermined distance above the rail (constant under normal conditions) and has at least one deformation zone allowing deformation or rupture during a derailment.
- An electrically conductive loop passes through the inside of the arm and its opening following a deformation or rupture of the arm produces information detected by an electrical arrangement transmitted to a generator then emitting an audible signal indicative of derailment, the stopping of the train being then either automatically or by decision of the driver to whom it will be necessary to take the necessary measures.
- a derailment prints him, hitting the rail,
- F x will often form, due to the forward speed, the predominant component, compared to the other two, (impact of the reader against an object on or near the rail, for example a block of ice, shock of an object against the reader just at the moment of the passage of the vehicle, for example a fragment of rock running down an embankment (where the component F Y may be less negligible), accidental strike against the reader to the stopping the vehicle, etc.).
- derailment is designed and constructed in such a way that its reader distinguishes in a way from the stresses to which it may be subjected by exercising an adequate and adapted function, depending on whether these mean derailment or not.
- the derail detection device comprises a double security module, the reader being able to act on one of the two modules or on the other, depending on the requests
- the derailment detection device by ideally solving the problem posed, overcomes the drawbacks noted on the devices of the prior art.
- FIG. 14 is a perspective view of the detector, the second security module of which responds to a third form of execution, and Figures 15 and 16 are sections of the detector shown in Figure 14, respectively in a plane XV and XVI thereof, the above figures are not all represented on a uniform scale. Moreover, and if necessary, all the identical elements in a figure are not
- the vehicle 2 comprises, on the one hand, two bogies 3 with double axle provided with wheels 5, for example one-piece or consist of a wheel body, full sail on which is wedged by a staple comprising a guide flange 6 on the inward facing side of a rail 8 placed on sleepers 8A.
- the momentary diameter W of the latter passes, after successive revisions, from a maximum (new wheel) to a minimum (wheel having reached a wear limit diameter), while the average lateral gap E between the outer (unreferenced) side faces of the guide flange 6 and the inside of the head 9 of the rail 8 varies in an interval [E M i N , E M AX].
- a lower face 97 of the reader 90 evolves above the rail at an average distance of the order of H can be maintained in a defined interval [H M IN, IX], thanks to a possible height adjustment of said reader.
- the reader 90 of at least one detector 1 is substantially at the right of the rail head ( Figures 3 and 4).
- each of the two wheels 5 of each of the two axles of a bogie 3 is associated with a detector 1.
- an assembly of two detectors 1 only per bogie 3, advantageously arranged diagonally, may be adopted.
- the vehicle 2 is provided, on the other hand, with a brake system known per se, pneumatic most often, or always when it comes to freight cars, with which system each detector is connected (in the broad sense of the term, that is, by material and / or immaterial means).
- the pneumatic system is shown schematically by a general pipe 11 and its brake coupling hoses 12.
- a connecting device comprises an auxiliary line 13 connected to the general line 11 by a bridge 14 via an emergency braking valve 15 (with air outlet symbolized by an arrow A) and,
- auxiliary pipe 13 is itself connected to the detectors 1 by ducts 17. It is clear that the auxiliary equipment 13, 14, 15, 16 and 17 can be arranged differently.
- the group of elements 15, 16 can be arranged at one end of the vehicle, which will improve its accessibility.
- the connection between the braking system and a detector 1 is established by the implementation of means, at least partly non-material (creation of an electrical voltage and electronic signals) .
- each detector 1 is fixed to a static part of the bogie 3, that is to say to an unsprung part of the vehicle 2, advantageously the lowest, ie, according to the type of bogie shown, at the bottom base 4 of the bearing box support, by means of fixing claws 100, 110 ( Figure 4).
- it is constructed and arranged taking into account defined parameters and constraints such as H, D ( Figure 3) and L ( Figure 6), so as not to interfere with the international "boilerplate" template. More particularly, it can not further hinder, in marshalling yards, a displacement or a braking of the vehicle carried out by means of suitable equipment (roller carriages, fixed track brakes, etc.).
- the reader 90 preferably consists of a vertical arm 91 and a sole 92, these two elements being either monolithic or rigidly connected (for example mechanically welded parts).
- the arm advantageously has a U-shaped section and at least one bore 95 of axis 10, preferably a series of bores (for example 4 in number) superimposed each biting into the bore (or bores) adjacent ( s), axes parallel to the axis 10 and contained in the plan VIII.
- the first security module of general reference 20 (FIG. 7), is a piece of shape defined by construction, provided with at least one breaking notch. According to the exemplary embodiment, it is a room with stages generally
- This first module 20 finally comprises a blind axial bore extending slightly beyond the groove 22 furthest away or, preferably and as
- two opposite blind coaxial holes 25A, 20A axis their depth extending slightly beyond each of the throat 22 nearest and their input being shaped so as to allow connection with one end of the conduit 17.
- the second security module 30 has the role, as mentioned, to absorb / neutralize stresses substantially lower than those caused by a derailment, but may accidentally occur and act on the drive. This absorption is obtained by exploiting elastic properties of at least one element that comprises this second security module, said absorption being able to be
- this second module 30 consists of a block 31 made of elastomer or other special rubber, of the silentbloc® type, arranged between the reader 90 and the first security module 20. It has an axial opening 32 on each side. part, axis 10.
- a threaded-end shaft 60 hereinafter first stud, has a head 61, a bearing 62, of circular section or polygonal, a shoulder 63, a worn 64 with section
- a subassembly proceeds from a translational and rotational fixing of this first pin 60 to the first security module 20 (according to the example, by welding the head 61 on a wall 26 of the central portion 21).
- the block 31, the section of the opening 32 and the outer section correspond respectively to those of the scope 62 of the first stud and the recess 28 of the module 20, is engaged in the latter until its face 33 comes abutting against the shoulder (not referenced) formed by the recess 28 and the bore 27, the block 31 thus being partially contained in said recess 28.
- the reader 90 is engaged by the bore 95 adequate on the scope 64 of the first stud, the diameter thereof being advantageously slightly greater than that of the bores 95 of the reader, so that there is a set ⁇ between these diameters.
- the superposition of the bores 95 is such that it ensures, in addition to an adjustable positioning of the reader relative to the rail, an additional safety connection in the axis ZZ 'with respect to the stud 60.
- the block 31 is capped by the U of the arm reader 90 against the face 98 which it comes to support. Shoulder 63 of the first stud 60 and length of the block 31 are dimensioned so that there remains, in the assembled state, a gap ⁇ between this shoulder 63 and the face 98 of the reader.
- the reader 90 is fixed on the first stud 60 by means of a clamping device 66.
- the horizontal section of the jaws is U-shaped (see Figures 6 to 16, more particularly 6, 7 and 9).
- the two parallel arms 101 of the inner claw 100 joined by a plate 102 provided with a central bore 103 10, they are oriented towards the rail 8. They each have a housing 104 to receive the pins 24 of the first security module 20 and a threaded hole 106, common axis for the attachment of this module 20 provided
- the arms 101 extend in height by having a V-shaped jaw 105 whose opening is oriented towards said plate 102.
- a reinforcing bar 107 ensures the stiffness of the claw. From the central bore 103 emerges the second pin 120 which is translationally connected to said plate 102.
- the second security module 30 and the reader 90 can be set up at this stage, said reader being engaged by the appropriate bore 95 on the span 64 of the first stud with a set ⁇ and fixed on it by a device 66, the superposition of the bores 95 being such that it provides additional security of connection in the axis ZZ 'of said reader relative to said pin.
- the conformation of the outer claw 110 is similar to that of the inner claw, the orientations of the wings 111 and V jaws 115 being reversed, and the plates 102, 112 of the two claws 100, 110 facing each other.
