Definitions
- the present invention relates to tower cranes whose boom, made of several successive elements hinged together, is foldable for the transport of the crane, in particular on the road. More specifically, the invention is concerned with crane jibs which have, towards their point, two elements of relatively short length, and it relates, again more precisely, to a device for simultaneously unfolding or folding such crane boom tip elements.
- This known system makes it possible to fold only one element of arrowhead, of a length not exceeding 2 meters. Moreover, he requires a specific engine.
- the invention relates to an unfolding device or folding of tower crane boom elements, the boom comprising a succession of elements articulated together in pairs around horizontal axes, these elements comprising at least two relatively long main elements, and at least two relatively short tip elements, the device being essentially characterized in that connecting members are provided connecting the front part of the last main boom element, the element arrowhead intermediate and the arrowhead end element, so as to unfold or fold simultaneously, in a plane vertical, of the two point elements relative to the remaining part of the boom, at least one tip element being foldable in a direction substantially perpendicular to the main elements, this device being powered by the crane lifting cable, and comprising, for this purpose, a unfolding arm carried by the front part of the last main element of the boom and fitted with a pulley for the passage of the lifting cable to the during unfolding or folding operations of the tip elements of the boom, the lifting cable then being attached to one of said elements peak.
- the lifting cable is, for example, attached to a swivel at the front end of the end element of the Arrowhead.
- the aforementioned connecting members include at least one connecting rod system, located in a vertical plane and linked, by articulations around horizontal axes, respectively at both tip elements and at the front part of the last main element of the arrow.
- the device can include two linkage systems symmetrical, arranged on each side of the arrow in vertical planes parallel.
- the or each connecting rod system allowing the unfolding or simultaneous folding of the two tip elements of the arrow, includes in one embodiment a three-point lever articulated by its point intermediate on a vertex of the intermediate arrowhead element, a front connecting rod articulated by one end at the front point of the lever and, by its other end, with the extreme arrowhead element, and a rear connecting rod articulated by one end at the rear point of the lever and, by its other end, with the front part of the last main element of the arrow.
- the lever and one of the connecting rods of the or each crankshaft system have respective holes coming in correspondence in the unfolded position of the arrowhead, and provided for pinning locking which immobilizes the lever with respect to this connecting rod, and which consequently immobilizes the entire crankshaft system, in aligned position.
- the linkage serves as a tie in the working position of the crane, with respect to the two tip elements of the arrow.
- This connecting rod can also serve as triangulation for the arrow unfolded on the ground, which is also a possible transport position on construction site.
- the unfolding arm is articulated around an axis horizontal on the front part of the last main element of the arrow, and includes stop and / or locking means for stopping it in deployed position in use and in the folded position against this element arrow main.
- the device which is the subject of the invention also includes a sling, attached to the front of the element end of the arrowhead, and intended to be hung on the rear end of the first main boom element, when this the latter is fully folded.
- a sling attached to the front of the element end of the arrowhead, and intended to be hung on the rear end of the first main boom element, when this the latter is fully folded.
- the device is motorized, in addition, by a jack used for general unfolding-folding of the boom, in particular a cylinder associated with an intermediate folding element, inserted between two main elements of the arrow; thanks to this cylinder, the last main boom element can be tilted and raised slightly, to release the arrowhead elements from the rear end of the boom foot, this allows the sling to be detached and unfolded advanced elements without these encountering an obstacle.
- a jack used for general unfolding-folding of the boom in particular a cylinder associated with an intermediate folding element, inserted between two main elements of the arrow; thanks to this cylinder, the last main boom element can be tilted and raised slightly, to release the arrowhead elements from the rear end of the boom foot, this allows the sling to be detached and unfolded advanced elements without these encountering an obstacle.
- the tower crane shown in Figure 1, includes a chassis base 1 which supports, by means of an orientation mechanism, a rotating chassis 2 on which is articulated, around a horizontal axis 3, a foldable mast 4 composed of a lower mast element 5 and an element upper mast 6.
- the upper mast element 6 carries, at its top, a crane boom 7 distributor, articulated around a horizontal axis 8 at top of the upper mast element 6.
- the arrow 7, constituting in the state aligned the raceway of a carriage 9, consists of itself, from back to front: from a first main jib element 10, from relatively long; an intermediate element 11 for folding arrow, of relatively short length; of a second main element of arrow 12, of relatively great length; of a first element of arrowhead 13, of relatively short length; and a second arrowhead element 14, of relatively short length, which constitutes the extreme element of the arrow 7. All these arrow elements 10 at 14 are articulated between them two by two, around horizontal axes, and are are aligned in the working position of the crane (Figure 1), to form the track of the carriage 9.
- a rigid arrow punch 15 At the base of the first main arrow element 10, also called arrow foot, is articulated a rigid arrow punch 15, inclined towards the rear of the crane in the working position.
- An arrow rod 16 connects the vertex 17 of the arrow punch 15 at a point 18 of the chord upper part of the jib foot 10.
- a jib retaining rod 19 connects the top 17 of the arrow punch 15 to the revolving frame 2, which carries another ballast 20.
- Motorized means 21 of the jack type are associated with the intermediate boom folding element 11, to allow the folding down of the second main arrow element 12 on the first main element of arrow 10.
- the arrowhead element 13 which is an element intermediate, is articulated at the front end of the second main element 12 along a horizontal axis 22. This articulation is achievable, on each side of the arrow 7, by a clevis-tenon system, the clevis being located for example on the intermediate element 13, while the tenon belongs to the main boom element 12.
- the intermediate element 13 seen from the side a triangular shape defining a vertex 23.
- the second arrowhead element 14 which is the element extreme, is articulated itself at the front end of the element intermediate 13, along another horizontal axis 24.
- This articulation is, also, achievable on each side of the arrow 7 by a clevis-tenon system, the yoke being located for example on the end element 14, while that the post is located on the intermediate element 13.
- the extreme element 14 is essentially straight, but it also has structures 25 defining a horizontal articulation axis 26.
- the unfolding-folding device intended for the two elements of arrowhead 13 and 14, includes two linkage systems 27, arranged symmetrically on each side of the arrow 7, in planes parallel verticals.
- Each linkage system 27 consists of a lever 28, a front link 29 and a rear link 30.
- the lever 28 which is a three-point lever, is articulated by its intermediate point on the vertex 23 of the intermediate element 13 of the arrowhead, around a transverse horizontal axis 31.
- This lever 28 has at its rear end a hole 32, intended for its locking in working position.
- the front link 29 is articulated, by one end, at the point of front articulation 33 of lever 28, along a horizontal axis. To his other end, the front link 29 is articulated with the end element 14 of the arrowhead, along the horizontal axis 26 previously mentioned.
- the rear connecting rod 30 is articulated, by one end, at the point rear articulation 34 of the lever 28, along a horizontal axis. To his other end, the rear link 30 is articulated, along a horizontal axis 35, with the front of the main boom element 12.
- This connecting rod 30 comprises a hole 36 for locking it in the working position.
- the unfolding-folding device also includes an arm for unfolding 37, articulated around a horizontal axis 38 on a crosspiece 39 (see Figure 3) integral with the front of the main boom element 12.
- the unfolding arm 37 comprises, at its free end, a pulley 40 intended at the passage of the lifting cable 41.
- This arm 37 has a cut in "V" shape 42, allowing it to rest on the cross-member 39 in position of use (for unfolding and folding the arrowhead elements 13 and 14).
- the unfolding arm 37 also includes means for locking by pinning in transport position, position in which it is folded back against the main boom element 12.
- the unfolding-folding device also includes a sling 43 (see Figure 2), fixed by loops on the front cross member 44 of the end element 14 of the arrowhead, and intended to hang (in folded transport position) on the rear end of the jib foot 10.
- the motorization of the movements of the device is ensured, on the one hand, by the lifting cable 41, the end of which is fixed by a swivel at the front end of the end element 14 of the tip of arrow, and on the other hand, by the jack 21 associated with the intermediate element of folding 11 and ensuring the general unfolding-folding of the boom 7.
- the lifting cable 41 is first given "slack", by the control of its winch.
- the unfolding arm 37 is unlocked, by withdrawn, and it is tilted manually to bring it into position operating reading, supported on the cross-member 39.
- the lifting cable 41 is then placed on the pulley 40 of the unfolding arm 37.
- arrow 7 is unfolded by a small angle, for example of the order of 5 °, as suggested by the arrow F in Figure 2, to raise slightly main element 12 and the region of the arrowhead, and allow the sling 43 to escape from the rear end of the jib foot 10.
- the lifting cable 41 is then tightened, which then pulls on the front end of the end element 14 of the arrowhead, and activates the two linkage systems 27, thus causing the opening simultaneous angle between the front element 14 and the intermediate element 13 of the arrowhead, and of the angle between the intermediate element 13 and the second main element 12 of the arrow.
- the movement thus initiated is continued, until the complete alignment of elements 12, 13 and 14 of the arrow - see the intermediate positions in Figures 5 and 6, and the position end of figure 7.
- the arrow 7 is then folded back, using the jack 21, to bring back the main element 12 in its initial low position, the arrowhead being now aligned with this main element 12.
Abstract
Description
- un transport de la grue et notamment de sa flèche dans un encombrement minimal, respectant le gabarit routier prescrit par les réglementations officielles, tout en maximisant la longueur utile de la flèche en position de travail ;
- un montage et un démontage de la grue dans un encombrement latéral minimal ;
- une réalisation simple et économique, évitant en particulier toute motorisation spécifique.
- Ce dispositif permet le repliage des deux éléments de pointe de la flèche, éléments dont la longueur additionnée peut être de l'ordre de 3300 mm, dans une hauteur disponible de l'ordre de 2100 mm, en respectant le gabarit hors tout normalisé pour les transports routiers, notamment par semi-remorque.
- Le dépliage ou le repliage de deux éléments de pointe de la flèche s'effectuent de façon simultanée, ce qui permet de réduire le nombre et la durée des opérations.
- Le dépliage ou le repliage s'effectuent en utilisant des motorisations existantes pour d'autres fonctions (câble de levage, vérin de dépliage-repliage général de la flèche), donc sans faire appel à une motorisation spécifique.
- Les opérations de dépliage et de repliage des éléments de pointe de la flèche ne demandent pas d'interventions manuelles nécessitant un effort important.
- Enfin, ces opérations de dépliage et de repliage deviennent réalisables dans un encombrement latéral minimal, réduit à la largeur des points d'appui au sol de la grue.
- en modifiant le détail de l'embiellage, par exemple en prévoyant un système d'embiellage simple et non pas double, ou d'autres organes de liaison entre les deux éléments de pointe de la flèche et le dernier élément principal de celle-ci ;
- en appliquant l'invention à la flèche d'une grue à tour à mât télescopique, et non pas à mât repliable.
