- the support device with lateral self-centering and longitudinal immobilisation is applied to the hitching pivot of a semitrailer, but it is conceivable to use it for other parts of vehicles, or even other integer or fractional loads. to stow on a wagon.
- the support device with lateral self-centering and immobilization longitudinal is called to be mounted at one end of a railway structure, for example a wagon.
- a wagon consisting of two bogies such as 1 whose rolling assembly consists of two axles 2 and 3 rotatably mounted on a bogie structure 4.
- This can be provided with a body 5 or not depending on the intended application. It may be a flat structure or a rear end platform 6 or front 7 as shown in Figure 1.
- the support device with lateral self-centering and longitudinal immobilization is composed of a rigid cowling part 8 which covers and mechanically protects a kingpin 9 of a semitrailer to be transported in the wagon. a receiver unit or nacelle 10 receiving self-centering cowling part 8 and elevation means of the receiver assembly 10.
- the receiver assembly 10 recalling in its general form that of a nacelle will be hereinafter nacelle 10.
- the nacelle 10 is intended to be mounted on a wagon structure, at one of its ends, for example on the rear platform 6 of the bogie, corresponding approximately to the location where the pivot of the bogie is usually located. hitch 9 when the semitrailer is immobilized in transport position on the wagon. As will be seen below, the nacelle 10 is articulated on this end of the wagon structure and on the end of a lifting means.
- the nacelle 10 is formed of a frame body 11 delimiting a receiving space 12 for the cowling part 8 which is self-centering in this housing. space.
- the frame 11 of the nacelle is formed of two end crosspieces 13 and 14 and two box-shaped spars 15 and 16, each forming a boundary and abutment border for lateral movements and self-centering.
- Each edge delimitation consists of a spar 15 or 16 which is extended laterally toward the receiving space 12 by an oblique ramp 1 centering 17 or 18 down the inclined plane towards the median plane of the receiving space 12 providing in these borders a cross section of generally trapezoidal shape.
- each ramp 17 or 18 forms, with the body of the corresponding spar, the caisson 15 or 16 enclosing a common hinge axis around which individual tilt elements pivot as a visual indicator, as will be seen hereinafter. after.
- the cowling part 8 is a generally trough-shaped body, that is to say a parallelepipedal body having two straight front faces 19 and 20, a large upper face 21 and a small lower face 22 and two oblique lateral faces 23 and 24. joining the upper face 21 to the lower face 22.
- the oblique faces 23 and 24 are self-centering ramps 1 cooperating with oblique ramps 1 centering 17 and 18 of the nacelle 10 to achieve automatic centering during the implementation of operations and securing the semitrailer by its kingpin.
- the cowling part 8 is a rigid hollow body that can be put in place on the kingpin with a fork 25 whose conical ends of the two branches 26 and 27 are engaged in gripping bores 28 and 29 provided in the body of the cowling piece 8.
- the internal volume of the cowling part 8 is compartmentalized into a cylindrical cavity 30 intended to receive the kingpin 9 and in two annexed volumes each containing a locking mechanism 31 and 32.
- each of these mechanisms 31 and 32 is formed, for example, of a locking pivoting finger 33 and 34 respectively between an inclined locking position in which the end of each finger condemns the movements. relative to the kingpin 9 and the cowling part 8 by blocking contact with the underside of the terminal disk 35 of the head of the kingpin and a retracted position of release.
- the holding of these fingers in the locked pivoted position is for example ensured as shown in the figures by pads 36 and 37 of elastic material of suitable shape providing the elastic return force.
- These locking fingers are each mounted pivoting about an axis 38 or 39 and each have a circular light 40 or 41 slightly offset from the inner hole of the gripping bore 28 or 29 in the inclined locking position of the corresponding finger and exactly in front of this orifice in the right position of release of this finger.
- the tilting maneuver of the locking fingers corresponding to the release is effected at the time of taking the cowling piece 8 with the fork 25 for its implementation on the kingpin or at the time of its taken to remove it using the fork 25 or any other similar tool.
- This blocking allows the cowling piece 8 to remain fixed on the kingpin and play its role for lateral self-centering and longitudinal immobilization.
- the light 40 or 41 of each locking pivoting finger 33 or 34 is placed in such a way that when the conical end of the corresponding branch of the fork passes through it, the locking finger is tilted in the retracted position. liberation simply by penetration.
- the nacelle 10 is formed of a mechanical support having in the upper part a receiving space 12 for the kingpin 9 dressed with its cowling part 8 and in the lower part a interface for its connection with a means of elevation.
- This tilting is a visual indication of the penetration of the cowling piece 8 in the receiving volume 12 and subsequently a visual indicator of the end of the implementation and setting operations before transport.
- the spars of the nacelle 10 forming the caissons 15 and 16 each house a pivot axis on each of which are mounted swinging a series of pivoting parts according to a principle substantially similar to that of the keys of a piano.
- These pivoting keys are parallel to each other and pivot for those located on the same side about a longitudinal axis for example housed in each box parallel to the longitudinal direction of the wagon.
- Each of these pivoting keys has a generally V-shaped portion protruding inside the receiving interior space 12 and another portion projecting outside the body of the nacelle.
- the pivoting keys are held at rest in the high position inside the nacelle by gravity, for example by a larger distribution of mass on the side located outside the body of the nacelle.
- the portion projecting outside the body of the nacelle 10 has a larger volume and therefore serves as a counterweight.
- the moving parts are in this first variant of the individual keys 42 juxtaposed in groupings 43 and 44 of rows one of right and the other of left. These groups 43 and 44 succeed each other in staggered rows, that is to say that they are spaced longitudinally from each other so that those of the rows of each spar are interwoven between the groups of the keys of the opposite box without significant discontinuity at the level of the interior space 12 of reception.
- the individual keys of the other variants are no longer divided into groups but follow one another continuously along each longitudinal side of the nacelle.
- These keys 42 each have a certain thickness constituting a first fractionation of the useful length of the nacelle 10, the second fraction being that of the groups.
- Each group 43 or 44 is composed of a plurality of individual keys 42 each in the form of a blade of a set of juxtaposed and independent blades in pivoting movement, each constituting an elementary key, so that one or two or even several blades of a group can be tilted while the others remain in place.
- each side an end group 45 and 46 for each of which the outer portions of the individual keys 42 have been curved due to lack of space.
- the thickness of these individual keys 42 is for example that of a sheet metal sheet.
- Each key 42 and each group 43 or 44 of juxtaposed keys affect, for example, a general shape of a sabot profile which is decomposed into a front portion 47 with a trapezoidal upper cutout, a rear heel 48 for position display and a pivot pivot central portion 49 (FIGS. 9 and 11).
- the central portion 49 has a bearing opening for pivoting about the corresponding tilting axis.
- the rear heel 48 is preferably of generally rectangular shape.
- the front portion 47 has a shape adapted to receive wedging the lower part of the cowling part 8 mounted on the kingpin 9 of the semitrailer. This reception and this stalling take place when the part 8 is in the lower position in the receiving space 12. At this moment, the self-centering is finished and the part 8 rests with its lower part on the receiving part of the keys. present under the projected surface of the body of the part 8, that is to say over a certain length of individual keys 42 as it appears in Figure 12 showing the offset.
- the succession of the keys, the distribution of these on each side of the nacelle 10 and the number of elementary keys 42 in each grouping 43 and 44 are studied with respect to the dimensional relationships of the parts involved, the thickness of the piece of cowling 8 so that each position of the latter corresponds to each side, the switching of at least one individual key.
- a variant shown in Figures 3 and 4 implements keys of different shape and differently distributed.
- each key 52 can be made in one piece in the form of blades as before, but of shorter length to leave a central free longitudinal space 53.
- they will preferably, but not necessarily, made as shown in Figures 13 and 15.
- each individual key 52 is formed first of a contact piece 54 inside the receiving space 12 sloping therein under the thrust against the cowling piece 8.
- Each contact piece 54 is pivotally articulated by its upper end on one end of a rocker arm 55 pivotally mounted on a common axis housed in the box of the frame of the nacelle 10. The other end of the rocker arm 55 actuates by contact pushing upwardly an outer pivoting piece 56 serving as an external visual indicator and counterweight.
- Each contact piece 54 has a particular cutting shape. It comprises a flat top and straight edge 57 serving as a contact surface or self-centering ramp to one or other of the oblique adjacent faces 23 or 24 of the cowling piece 8 opposite. It also comprises an oblique base 58 serving as abutment support in its low inclined position. The part opposite the upper contact edge 57 has a convex cut-out 59 terminated upwards by a rounded profile 60. The upward movement is ensured by the force of gravity provided by the weight of the external pivoting piece 56 in support on the rocker arm 55. As indicated, the keys 52 in this variant are of shorter length than in the previous variant so as to arrange between their ends facing the longitudinal space 53 for the cowling part 8.
- FIGS. and 4 There is shown in Figures 17 to 21 a third variant of the nacelle 10 showing tilting parts 61 slightly different for lateral self-centering and longitudinal immobilization with visual indicator. These moving parts are always pivotally mounted blades 61 in continuous succession and in two rows 62 and 63 about two longitudinal axes 64 and 65 carried by the cross members of the frame of the nacelle 10.
- the frame has a base 66 by which it is articulated at the upper part of the elevating means through an interface 67.
- the base 66 is formed of a plate 68 whose upper face 69 constitutes a self-centering abutment for the pivoting blades 61 while the longitudinal lateral faces 70 and 71 the edge of this plate 68 constitute a raised position stop for these same individual pivoting blades 61.
- the individual swivel blades 61 are pivotally mounted in one row 62 on the same side and in another row 63 on the opposite side.
- each blade has a front portion 72 of generally triangular shape recessed at its center whose base has a cutout 73 with two bearing abutment zones against the upper face of the plate 68.
- the front portion 72 has a front edge 74 straight, oblique plane and to serve as self-centering ramp 1 cooperating with the inclined ramp facing the piece cowling 8.
- Each blade 61 continues with a median portion 75 at the top of the front portion 72 in the form of a triangle, by which it is pivotally mounted free on the axis 64 or 65 corresponding pivoting.
- Each blade 61 terminates in a rear portion 76 external to the basket of generally angled shape whose inner edge 77 abuts against the corresponding longitudinal lateral face 70 or 71 of the longitudinal edge of the frame when the blade 61 is in position. raised position of rest.
- the rear portion 76 has an upper edge 78.
- a motion damping device (not shown) between the head of the end of the elevating motor means and the nacelle 10.
- FIG. 22 An addition to the means of elevation and lowering of the support device according to the invention is shown in FIG. 22.
- This additional means consists of a sensor element 81 allowing from an initial position of the nacelle 10 during its first adjustment displacement to provide a detection signal for determining the initial reference value which will be used for the adjustment in final position of the nacelle as will be described below with reference to Figures 23 to 26.
- FIG. 22 relates to a contact element 82 which protrudes beyond the upper plane of the nacelle 10.
- This contact element 82 is made in the example shown in the form of FIG. a compression spring 83, preferably prestressed, whose free end is a flat surface contact and bearing surface 84 on the facing surface 85 of the underside of the frame of the semi-trailer or the pivot spring bed 86 coupling. It can also be a probe.
- This sensor element or probe can be mounted on the tail or the guide arm 79 of the nacelle 10 via a suitable support. For reasons of symmetry one can provide two detector elements in parallel on each side of the nacelle.
- the arm or the guide tail 79 has a sliding sleeve 87 for its guided movement along the column of the elevating means (FIG. 22).
- the bushing-type guiding elements 80 and 87 act as a tilting limiter of the nacelle 10 at the moment of docking and self-centering with immobilization of the kingpin 9, but also throughout the transport. For this purpose, there is a certain clearance between these guide elements and the arm or tail 79 ensuring a limited pitch travel.
- the free end 84 of the compression spring 83 will first come into abutting contact with the underside facing 85 of the chassis of the semi-trailer in the vicinity of its kingpin. This abutment contact will be followed by a short compression stroke of the spring which will provide resistance to the thrust in elevation. This modification may result in an end of thrust signal, this signal being used to derive a reference dimension.
- the detector arm 81 has been shown on the right, which does not correspond to its normal location when considering the other figures. To facilitate understanding, we refer to the different displacements and distances in the following way and we state some definitions.
- Zo initial height or initial reference point relative to the ground, namely that of the underside of the semitrailer frame at its kingpin.
- Zd height or final dimension with respect to the ground after self-centering and immobilization.
- ⁇ Z lowering the height of the load plan until the end of the self-centering (or lowering of the crutches).
- ⁇ zo initial displacement of the nacelle until stop contact.
- ⁇ zi displacement of the nacelle to its final position.
- NO height or initial dimension of the nacelle relative to the ground.
- Ni height or dimension of the nacelle with respect to the ground during contact of the stop detector.
- Nd height or final dimension of the nacelle with respect to the ground or dimension d 1 self-centering.
- the loading plan which is the support on which the semitrailer in the car is based is mobile.
- the following setting with the detection device applies both in the case of a lowering of the semi-trailer by crutches crutches or for loading by crane.
- the semi-trailer is in a high position supported by its crutches or by an external lifting device or, on a vertically movable loading plan.
- the semi-trailer or rather the underside 85 of its chassis at the kingpin is at a height Zo relative to the ground and at a height or dimension H relative to the load plane because hypothesis relating to the case examined, its position remains fixed with respect to this one.
- the nacelle 10 is in its initial position at NO relative to the ground (FIG. 23).
- the platform 10 is raised by its elevation means until the detection device 81 arrives via the surface 84 of its detector 81 in abutting contact with the zone 85 opposite. of the underside of the semi-trailer chassis ( Figure 24).
- the nacelle 10 stops climbing to a precise height for example when crossing a pressure threshold.
- the nacelle moved from ⁇ zo upwards to a new height or dimension Ni ( Figure 24).
- the nacelle 10 is then lowered or raised to its final position by a displacement of a value ⁇ zi known in advance to reach the final Nd of the nacelle ( Figure 25) also known in advance by construction and function characteristics of the system corresponding to the stroke ⁇ Z which is the lowering stroke of the loading plane.
- Nd determines the final position of the nacelle 10 taking into account the known final position (Zd dimension) of the underside of the frame of the semitrailer.
- a precise reference position of the nacelle is established from any initial position thereof. This is the universal aspect of the process that fits all types of wagon bi-modal carrier.
- the nacelle 10 is articulated to a support assembly 88 ( Figures 29 and 31 to 34).
- This support assembly 88 consists of a connecting table 89 lying flat on the bogie structure, which allows it to provide the nacelle 10 stability around the roll axis.
- This connecting table 89 is pivotally articulated at its rear end on the bogie structure by means of two supports 90 and 91 in movable lateral pieces, for example translational light in each of which is brought to pivot and translation a bearing pivot that the connecting table 89 has at the front end of each of its songs for the variant shown in Figure 29.
- the link table 89 is thus free in longitudinal movement movements and pivoting upwards.
- the connecting table 89 is articulated to the bogie structure through an intermediate tilt plate 92 mounted at each of its long sides each time by a pivot joint.
- the connecting table 89 is also connected articulated by its front end to the rear cross member of the frame of the nacelle 10 by two symmetrical pivoting joints 93 and 94 fulfilling the general function of a hinge for example in the form of each time d a clevis receiving between its two wings a landing end, the assembly of the articulation being traversed by a pivot axis laterally blocked.
- This articulated linkage structure of the nacelle 10 with the bogie structure gives the link table 89 sufficient clearance in longitudinal and vertical movements relative to the wagon to allow the nacelle to lower and rise.
- the nacelle 10 is mounted at its lower end on an elevating and lowering means which is intended to move the nacelle 10 in upward or downward vertical movements.
- the first elevating means 95 for lifting the semitrailer by its kingpin and to support the assembly during transport while the second Elevation means 96 provides the simple elevation of the nacelle 10 to the desired position corresponding to the dimensions of the semi-trailer for self-centering, immobilization and support of the assembly during transport.
- the lifting means also ensures the longitudinal maintenance of the body of the nacelle.
- An exemplary embodiment of the first lifting means 95 visible in FIG. 27 and shown in isolation in FIG. 28 comprises a lifting cylinder 97 whose end of the rod is articulated on the base of the platform 10 by a device of FIG. multidirectional articu-lation 98 allowing vertical translation movements with a clearance game.
- This articulation device 98 is guided in its translation movements by two columns 99 and 100 disposed on either side of the lifting jack 97.
- This first lifting means 95 not only allows the trailer to be lifted by its kingpin 9, but also its support during transport.
- FIG. 29 to 34 An exemplary embodiment of the second elevation means 96 is shown in Figures 29 to 34.
- This means does not allow the lifting of the semitrailer by its coupling pin 9. It is manual and bilaterally controlled, it that is to say from either side of the wagon for ease of use.
- This embodiment consists of a screw jack 101 with bilateral control whose head 102 it engages with the lower part of the pod 10, that is to say the underside of its body.
- the screw of the screw jack 101 is housed in a vertical support 103 of the column or pole type mounted on the bottom of the wagon.
- This vertical support 103 is surmounted by a housing 104 housing a motor element, for example a motor nut with ratchet wheel 105.
- the ratchet wheel is part of a locking mechanism 106 with ratchet for locking in a given position to using an articulated assembly 107 to bilateral control, that is to say symmetrical on each side of the car, each time via a rod 108 and 109 each leading to a respective control support 110 , 111 with integrated tilt handle 112, 113, each support being fixed on the upper edge of the corresponding part of the bogie structure.
- each tilting handle 112 or 113 of each control support 110 or 111 indicates the state in which the locking mechanism 106 of the lifting screw of the screw jack 101 is located.
- each side of the wagon a cardan drive link.
- the drive of the jack is effected either by means of a portable external motor whose output is coupled to or engaged in the end of the drive link for power take-off 114 or 115, or manually using a key or crank tool.
- the hitching pin 9 of the semitrailer is first dressed by means of the cowling piece 8 which comes into abutting contact with the bed base 86 of the front part of the chassis of the semitrailer.
- the cowling part 8 is taken manually by engaging the branches 26 or 27 of the fork 25 each in a gripping bore 28 or 29.
- the engagement of the conical tip of each branch has the effect of bringing each locking pin 33 or
- cowling piece 8 is thus placed on the kingpin 9 by engaging it through its inlet opening in a cylindrical cavity 30.
- the semi-trailer is then placed by external means or by its own means in the wagon that will transport it.
- the semi-trailer is already but roughly centered laterally when it is placed on the wagon.
- It may be a wagon s' pivotally opening its carrier structure around a center of pivoting median or pocket car or other wagon suitable for the transport of semi-trailers.
- the pivot 9 and its cowling part 8 are located after closing the wagon over the nacelle 10.
- start berthing operations comprising 1 self-centering, at the end of which the trailer will be immobilized by self-centering with longitudinal immobilization of the kingpin 9 of the semi-trailer.
- the lifting means once the cowling piece 8 is in place on the king pin 9, the operation of the support device with lateral self-centering and longitudinal immobilization of a kingpin of a semi-trailer according to the invention takes place in two phases.
- the lifting assembly 95 with hydraulic or pneumatic jack 97 enables self-centering and locking under load. From then on, the self-centering-locking operations are quite simple.
- the hydraulic cylinder 97 is controlled uphill. By a lifting movement, the nacelle 10 comes closer to the cowling part 8 which is furnished with the kingpin 9.
- the rod of the hydraulic cylinder 97 pushes the nacelle 10 upwards, first until contact with the cowling part 8 and until relief of the crutches of the semi-trailer.
- This upward movement is followed by a self-centering phase during which the reception space 12 rises towards the cowling part 8 which automatically centers itself in the platform 10 by the play of the lateral ramps of the nacelle and the cowling part, and thus the semitrailer also centers itself.
- the cowling piece 8 When the cowling piece 8 is fully engaged in the receiving space 12, it controls an additional thrust of the lifting cylinder 97 until the upper plane of the platform 10 comes into contact with the springboard 86 of the kingpin 9 and the crutches are fully unloaded to allow load transport.
- the docking phase of the nacelle associated with elevation means 96 of the second category, namely the screw jack 101, is slightly different.
- the course of the nacelle 10 is determined beforehand and converted into the number of revolutions of the screw or its drive control or a control indicator. At the end of the race, the drive motor will stop automatically because it will be programmed.
- the screw jack 101 is controlled upward by a value corresponding to the measurement of the bed base level 86 of the kingpin of the semi-trailer (a measure that has been previously performed by the acquisition system level). In their inner parts to the basket all the keys are in the high position by gravity.
- the semitrailer is lowered and the complementary shape of the cowling part 8 allows gravity self-centering of the kingpin 9 in the receiving space 12 of the nacelle 10.
- the pivoting keys located under the cowling part 8 rock while their neighbors remain in place and realize the longitudinal locking of the cowling part 8 relative to the platform 10 while the lateral locking results from the self-centering by the V-shaped receiving form.
- the cowling part 8 is fully lowered, the upper plane of the nacelle 10 is in contact with the frame 86 of the kingpin 9 of the semi-trailer and the legs are then slightly relieved.
- the locking in position of the jack screw 101 performs the load recovery of the semi-trailer.
- the pivoting keys in contact with the base of the cowling piece 8 are in the lowered position inside the receiving volume 12 of the nacelle.
- the other pivoting keys that is to say those that are not in contact with the cowling part 8 are not depressed and are therefore in the up position inside the nacelle, which allows them to block the cowling part in longitudinal movements.
- the process ends with the unloading of the crutches of the semi-trailer.
- the platform 10 is designed such that, regardless of the longitudinal position of the kingpin 9, at least one key is pressed on each side inside the nacelle.
- the depression of the keys is reflected on the outside of each side of the wagon by a raised position of the outer part of the keys concerned which thus serves as a bilateral visual witness of self-centering and immobilization.
- this verification consists in observing that at least the outer part of a key, on one side or the other, is in a different position than that of others and that the upper plane of the nacelle 10 is in contact with the frame 86 of the pivot 9 of the semi-trailer.
