Abstract
Description
-i- tes sociétés d'exploitation des hippodromes qui proposent à la fois des courses de plat et des courses de haies lors de la même réunion ont tout intérêt à ne pas multiplier le nombre de piste pour des raisons de coût d'entretien, mais aussi pour que la ligne droite d'arrivée se situe au plus près des spectateurs. Pour cela il suffit que les haies ou tout du moins celles de la ligne droite d'arrivée puissent être escamotées après le passage des chevaux. Cette opération peut se faire soit entre une course plate et une course de haie, ou même pendant la course de haie elle-même entre deux tours de piste. Il faut tenir compte de la largeur normalisée des haies qui est de 14 m pour les plus grandes courses . i0 L'opération d'escamotage de la haie doit alors être simple à réaliser, rapide et surtout d'une très grande fiabilité. On utilise en général, une haie mobile sur pivot, elle peut comporter une roue en bout qui repose sur la piste pendant la rotation. II en résulte alors la marque de la roue en arc de cercle qui vient s'imprimer dans la piste 15 et lui laisse un sillon persistant. On utilise alors plus généralement un système de vérin hydraulique qui permet de surélever la haie pendant l'opération de rotation. La haie est alors en porte à faux et peux tourner autour de son pivot. L'inconvénient majeur de ce système est d'introduire un équipement élaboré (pompe hydraulique, tuyau, vérin hydraulique, articulation horizontale) sujet à défaillances potentielles. Si 20 l'un de ces éléments tombe en panne, il sera alors difficile de déplacer la haie en quelques minutes. -the racetrack operating companies that offer both flat races and hurdles races at the same meeting have every interest in not multiplying the number of tracks for reasons of maintenance cost, but so that the finish line is closer to the spectators. For that it is enough that the hedges or at least those of the straight line of arrival can be retracted after the passage of the horses. This can be done between a flat race and a hurdle race, or even during the hurdle race itself between two laps. The standardized hedge width of 14 m should be taken into account for larger races. The retraction operation of the hedge must then be simple to carry out, fast and above all very reliable. In general, a hedge movable pivot, it may include an end wheel that rests on the track during rotation. This then results in the mark of the wheel in an arc that comes to print in the track 15 and leaves him a persistent groove. More generally, a hydraulic jack system is used which makes it possible to raise the hedge during the rotation operation. The hedge is then cantilevered and can turn around its pivot. The major disadvantage of this system is to introduce an elaborate equipment (hydraulic pump, pipe, hydraulic cylinder, horizontal joint) subject to potential failures. If one of these elements fails, it will be difficult to move the hedge in a few minutes.
La présente invention a pour but, tout en conservant le principe du pivot, de n'utiliser que des équipements simples et" parfaitement fiables. C'est donc la 25 conception du principe de rotation qui permettra de supprimer tout organe susceptible de provoquer une défaillance. The present invention aims, while retaining the principle of the pivot, to use only simple equipment and "perfectly reliable." It is therefore the design of the principle of rotation that will remove any organ likely to cause a failure .
La structure de la haie (fig. 2), qui doit permettre de supporter le porte à faux de 14 m avec un minimum de déformation, est en acier ou aluminium avec 30 triangulation. Chaque élément de la structure est calculé séparément afin d'être optimisé au plus proche de la limite élastique . The structure of the hedge (Figure 2), which is designed to support the 14 m overhang with minimal deformation, is made of steel or aluminum with triangulation. Each element of the structure is calculated separately in order to be optimized closer to the elastic limit.
A l'opposé du pivot (1), est installé un système de surélévation manuel (9) qui viendra bloquer et supporter la haie. Il peut s'agir d'une béquille (fig. 3), composée 35 d'un poteau (2) qui s'appuie sur une large platine (3) munie de picots (4). Cet ensemble est animé d'un mouvement horizontal dont le but est d'abaisser la platine à picots d'une quinzaine de cm. La haie qui reposait librement en porte à faux à quelques cm du sol va se trouver surélevée d'une dizaine de cm et devenir ainsi horizontale où parallèle à la piste. Une part du poids total de la haie va alors être 40 supportée par la béquille et la platine dont les picots se sont enfoncés dans le sol. On obtient ainsi une grande stabilité de la haie afin qu'elle reste en place lors du passage des chevaux. Opposite the pivot (1), is installed a manual elevation system (9) which will block and support the hedge. It may be a stand (FIG 3) composed of a pole (2) which is supported on a large plate (3) provided with pins (4). This set is animated by a horizontal movement whose purpose is to lower the platinum pins of about fifteen cm. The hedge that rested freely cantilevered a few cm from the ground will be raised a dozen cm and become horizontal or parallel to the track. Part of the total weight of the hedge will then be supported by the crutch and the platen, the pins of which have sunk into the ground. This gives a great stability of the hedge so that it remains in place during the passage of horses.
L'opération de descente de la béquille est réalisée par un système de 45 biellettes (5), les deux biellettes médianes (6) sont reliées à un manche (7) qui permet de mouvoir l'ensemble manuellement, le principe de la grenouillère est utilisé pour le maintien en position basse . The operation of descent of the stand is carried out by a system of 45 links (5), the two median links (6) are connected to a handle (7) which allows to move the assembly manually, the principle of the toggle is used for holding down.
La béquille peut également être reliée à un cric à vis sans fin ou hydraulique . 2952551 -2- Le pivot de la haie (1) est constitué d'un mat en tube comportant des platines pour supporter les paliers (8). Les paliers intègrent des roulements à rotule sur rouleaux calculés pour absorber la charge statique du couple de la haie en porte à faux. Le pied du pivot, qui descend profondément dans le sol, est noyé dans un dé en béton suffisamment volumineux pour assurer la rigidité du pivot quand la haie est en porte à faux. io 15 The stand can also be connected to a worm or hydraulic jack. The pivot of the hedge (1) consists of a tube mat having platens for supporting the bearings (8). The bearings incorporate spherical roller bearings calculated to absorb the static load torque of the cantilever hedge. The foot of the pivot, which descends deeply into the ground, is embedded in a sufficiently large concrete die to ensure the rigidity of the pivot when the hedge is cantilevered. io 15
