Definitions

the present invention relates to a tower crane automated assembly with folding boom, consisting of several boom elements hinged to each other.
the "mounting" of the crane means its unfolding or deployment, of its folded transport position to its working position, the reverse operation of changing from the working position to the transport position being folding.
the invention is more particularly related to a device of articulation of the boom, inserted between two elements of this arrow in view of its lateral folding for its road transport.
the invention thus applies to tower cranes automated assembly which must be folded for their road transport, from one site to another or from one location at another, in the best conditions possible speed, security and space.
the invention is more particularly interested to a tower crane equipped with a foldable jib made up at least three boom elements, which can be different lengths or even different cross-sections each other, the folding of the boom taking place in the vertical plane, according to a folding principle "in accordion "or” spiral ", and part of the arrow folded up taking place on the side of the crane mast, view of storage and transport of the crane in a minimum space requirement.
a type of known solution, to which the present invention relates consists in provide between two main boom elements consecutive, especially between the first element called “foot arrow "and the next arrow element, a short intermediate element, making an articulated connection between the two main elements considered.
Such intermediate boom folding element is described by example, in French patent 2,368,430 and the application European patent 0,733,584.
this document shows a crane boom in three elements, foldable in accordion in the plan vertical, and also foldable in the horizontal plane for transportation.
An intermediate element connects the foot of arrow with the next arrow element, the second arrow element.
the intermediate element constituting a section of folding of the arrow, is formed of two trihedrons.
a rear trihedron is connected to its base in an articulated manner boom foot, at the level of the lower members, by two opposite axes.
This rear trihedron is also connected to the level of its top, via a tie rod, to an intermediate punch.
a front trihedron is connected to its hinged base to the second boom element, to the frame level, by two opposite axes.
This trihedron front is also connected at the level of its top, by through a tie rod, to the second element of arrow.
the two trihedra are linked together by a hinge, located in the vertical median plane of the arrow, at an oblique edge of each trihedron.
Two removable bars secure the members lower of the two boom elements, in position work, to ensure the continuity of the raceway of the boom carriage.
This known device does not allow the unfolding / folding in the vertical plane of an arrow in three elements, folded back on itself.
this device does not allow the folding of an arrow in the horizontal plane, at an angle of 180 °, since the hinge is located in the median plane of the elements of arrow.
the need to set up and removal of the two removable bars constitutes a complication.
European patent application No. 0.733.584 provides an intermediate boom folding element which is monobloc and rigid structure, not composed of two parts hinged together. This achievement remains thus structurally distant from the object of this invention, and it only offers limited possibilities boom folding.
German patent application No. 3,032,823 describes a crane boom of which two main elements are hinged together directly, without element folding intermediate, along a vertical offset axis laterally. This device only allows folding lateral, in the horizontal plane, of a portion of the arrowhead element, arranged horizontally. In this case also, the possibilities of folding the arrow therefore remain very limited.
the present invention aims to eliminate these disadvantages, providing a self-erecting crane automated folding boom with an intermediate element folding system designed to allow the unfolding / folding of the arrow in the vertical plane, and also to allow the unfolding / folding the front part of the boom in the horizontal plane, while offering a solution for the trolley storage.
the lateral offset of the hinge, connecting articulated way the two parts of the element boom folding intermediate, allows pivoting of the front part, relative to the part rear, at an angle of 180 °.
This hinge is advantageously achievable in two parts, one lower hinge part located at low height above rectangular bases of the rear parts and pyramid-shaped front, and a hinge part upper, located substantially at the level of the summits said rear and front parts of pyramidal shape.
the arrangement which is the subject of the invention allows to meet the constraints of the road gauge or even at a lower gauge, storing the second and third arrow elements on the side of the package, in a plane parallel to that containing the crane mast and the boom foot, while the boom carriage is stored at the rear of the folded crane.
the proposed configuration allows the operation of folding / unfolding of the boom in the horizontal plane, i.e. the 180 ° pivoting movement allowed by the vertical axis hinge, at ground level or less at breast height, manually and effortlessly particular.
the solution according to the invention eliminates all dimensional constraints regarding the construction height of the boom elements, unlike the particular configuration described in the aforementioned European patent application 0.733.584.
the tower crane shown very schematically on Figure 1, comprises in known manner a base frame 1 on which is mounted a rotating chassis 2, orientable around a vertical axis 3.
the rotating chassis 2 carries, at the rear, a counterweight 4 and, at the front, a mast telescopic 5.
This crane has a boom dispenser 6, unfoldable and foldable, produced in three successive main elements, of relatively large length, designated respectively as jib foot 7, second arrow element 8 and arrowhead 9.
Two intermediate boom folding elements 10 and 11, of relatively short length, are inserted here respectively between the two arrow elements main 7 and 8, and between the two arrow elements main 8 and 9.
mast 5 is straightened in an upright position, and all the elements of arrow 7 to 11 are aligned in a horizontal position.
a boom carriage 12 is movable along the length of the arrow 6.
the crane also includes a rear device for retainer 13, connecting the arrow 6 to the rotating frame 2, as well as a mast lifting device.
the structure of the second intermediate boom folding element 11, inserted between the second arrow element 8 and the arrowhead 9, can be similar to that described in European patent application 0733584 in the name of Applicant.
first intermediate element of arrow folding 10 is shown in detail in Figures 5 and 6.
This intermediate element 10 is itself composed of two parts, a rear part 15 and a part before 16, which both have a shape general pyramid with rectangular base.
the rear part 15 of the intermediate element 10 has two parallel lower members 17, joined together at their ends by crosspieces 18, which defines its rectangular base.
the posterior ends of both lower members 17 are extended by studs respective 19, by which the rear part 15 is articulated, along a horizontal transverse axis 20, with the front end of the jib foot 7 at the level of the lower members 21 of the latter.
the part front 16 of the intermediate element 10 has two parallel lower members 26, joined at their ends by crosspieces 27 and also by a diagonal 28, which defines its rectangular base.
the extremities anterior of the two lower members 26 are extended by respective studs 29, by which the front part 16 is articulated, along a horizontal axis transverse 30, at the rear end of the second element of boom 8 at the level of the lower members 31 of this item 8.
the two parts 15 and 16 of the intermediate element 10 can pivot one by relative to each other, around the vertical axis 37, along a 180 ° angle between a so-called “folded” position ( Figure 5) in which these two parts 15 and 16 are arranged side by side, and a so-called “unfolded” position ( Figure 6) in which these two parts 15 and 16 are placed one in continuation of the other.
a connecting axis (not shown) secures the two jib elements 8 and 9 with the mast 5.
the boom carriage 12 in the folded transport position, the boom carriage 12 is stored on the rear part 15 of the intermediate boom folding element 10.
the crane folded in this way takes up minimal space and can be towed on the road, by a vehicle 51, in the manner a trailer or semi-trailer, the vehicle tractor 51 being coupled at the end opposite to that where the boom carriage 12 is stored.
the crane can also be transported on a site, from one point to another, with its arrow 6 no laterally folded, the second boom element 8 and the arrowhead 9 then overcoming the assembly constituted by the mast 5 and the boom foot 7. In this position, the rear 15 and front 16 parts of the element intermediate 10 remain united.
Figures 7 to 10 show, in correspondence with Figures 1 to 4, a collapsible jib crane 6 "in accordion ", in which an intermediate element of arrow folding 10 is still inserted between the foot of arrow 7 and the second arrow element 8, while the second intermediate boom folding element is removed, arrowhead 9 being directly articulated to the second jib element 8 at the lower members, along a horizontal axis 52.
the intermediate element 10 is here more short, especially in its front part 16, but for the essentials its structure is identical to the description previously given. Thanks to its hinge, this element intermediate 10 always allows to place, in position transport (drawn in solid lines in Figures 8 and 9), the second arrow element 8 and the arrow tip 9 on one side of the mast 5 and the boom 7.
