Definitions

  • the present invention relates to a method and a device for mounting of the components of the rotating part of a tower crane, this invention focusing more particularly on the constitution and mounting the mast head of tower cranes.
  • the rotating part of such a crane comprises usually a rotating pivot, surmounted by a mast head also called “Arrow-holder", the arrow and the counter-arrow being located on either side of the masthead.
  • the arrow is articulated, by its posterior end, to the face front of the arrowhead, and it is held substantially in position horizontal by means of one or more lines of arrow rods, connecting each obliquely the top of the arrowhead at a point on the arrow.
  • the counter-jib is articulated, by its anterior end, to the rear face of the arrowhead, and it is held in position substantially horizontal by means of one or more lines of tie bars, each connecting obliquely the top of the arrowhead to a point on the counter-arrow.
  • European patent application EP 0 635 450 A1 in the name of Applicant describes a method for mounting the distributing boom and the jib of such a tower crane. According to this process, the elements of arrow are aligned and assembled on the ground with their tie rods, then we raise and aligns the tie rods, and possibly those of the jib, using an auxiliary assembly machine such as a mobile crane. Then, using the same machine, we lift the whole boom or counter-jib with the tie rods, and the jib or counterjib is presented opposite the masthead previously mounted, so that the free ends of the tie lines appear correctly at the top of the mast head, allowing a direct pinning of the tie rods at the top of the masthead.
  • This process is also implemented by aligning and assembling the boom elements on the ground, and using an auxiliary machine lifting to present the jib, then the jib, facing the masthead previously assembled.
  • the invention is essentially based on the initial separation of the two-part arrowhead, respectively a front part and a part rear, which allows two separate assemblies to be pre-assembled on the ground, one comprising the jib and the rear part of the jib holder, and the other the arrow and the front part of the arrow holder. These two pre-assembled assemblies are then successively lifted and assembled to the turning pivot or to the top of the mast-cabin by pinout.
  • the two constituent parts of the arrowhead are also linked together by broaching, in their upper portions, of so as to ultimately constitute a complete, rigid, looking arrowhead triangular or polygonal (seen from the side).
  • the assembly on the ground of the assembly formed by the arrow, its tie (s) and the front part of the arrow holder is made by tying articulated the base of the front part of the arrowhead at the end posterior of the boom foot, and also linking the front part of the boom holder at the jib foot by a means limiting pivoting, forward and toward the rear of the front part of the arrowhead relative to the arrow.
  • the angular travel thus authorized, for example of the order of 5 °, facilitates the final operation of connecting the tops of the front and rear parts of the arrowhead.
  • the assembly operation on the ground of the assembly formed by the arrow, its tie rod (s) and the front part of the arrow holder also includes, for the or each drawing of the arrow, the fixing of a rear part of the tie rod at the top of the front part of the jib holder, the fixing of a front part of the same tie at an intermediate point of the arrow, bringing the rear and front parts of the tie together using a sling pulled by an auxiliary handling or lifting device, and the pinout of the front end of the rear part of the tie rod on the rear end of the front part of the tie rod.
  • the tie rods are thus pinned together, by ground operations, and they find themselves in an aligned position.
  • the lifting operation of the assembly formed by the jib, its or its tie rods and the rear part of the arrow holder is achievable, according to a first method of implementation, using slings comprising front slings attached to the base of the rear part of the arrowhead, and passing over a deflection member carried by this rear part, and rear slings attached to the structure of the jib, so as to maintain the structure of the substantially horizontal jib during the lifting of this assembly and its pinout on the turning pivot or the mast-cabin, the tie rods of the jib being aligned and tensioned.
  • the lifting operation of the assembly formed by the jib, its or its tie rods and the rear part of the arrow holder is made using slings comprising front slings attached to the base of the rear part of the arrowhead, but not deflected, and rear slings attached to the strut structure, the slings being long adapted to maintain the structure of the jib in an inclined position by with respect to the horizontal, during the lifting of this assembly and its pinout on the turning pivot or the mast-cabin, the rear part of the boom holder being pivoted back and in abutment, so that the tie rod (s) remain relaxed; the structure of the jib is brought back to the horizontal, and the or the tie rods are tensioned, after pinning of said assembly on the pivot rotating or mast-cabin.
  • the process still advantageously comprises, after the broaching operation of the first of these sets on the turning pivot or the mast-cabin, the realization of a provisional connection with clearance maintaining the rear part of the arrow holder in upright position, waiting for the pinout of the top of the front part of the arrowhead on the top of said rear part.
  • This temporary connection with play is achievable by means of retaining rods and lights, connecting the top of the rear part of the arrow holder with swivel pivot or cabin mast.
  • the lifting operation of the assembly formed by the boom, its or its tie rods and the front part of the jib holder is also carried out using slings preferably by keeping the arrow substantially horizontal until its broaching on the swivel pivot or the mast-cabin, then by rotating the boom slightly upwards around the axis making this pinout, to make a approach pinout with clearance between the top of the front part and the top of the rear part of the arrowhead. Then there is a pivot reverse of the arrow driving forward the rear part of the arrow holder, and carrying out a final pinout.
  • the pivoting reverse of the arrow driving forward thanks to its dead weight more import the rear part of the arrow holder, move the broaching hole definitive of the summit of said rear part following an arc of a circle, the center corresponds to the broaching axis of the jib and the rear part of the boom holder on the turning pivot or the mast-cabin.
  • the final broaching hole at the top of the front part of the arrowhead is moves along another arc, the center of which corresponds to the axis of pin assignment of the arrow and the front part of the arrow holder on the turning pivot or the mast-cabin.
  • the final pin holes respective vertices of the two parts of the arrowhead are sure to find a common axis, at the point of intersection of the two arcs of circle mentioned, whatever the starting geometrical position of these broaching holes, and thus the realization of the final pinout is always possible.
  • this final pinout ensures the stiffening of the arrow holder, necessary for it to perform its function when working the crane.
  • the front part of the arrow holder is connected, via a crutch made up of two sections uneven articulated between them, at the rear part of the boom foot, one of the sections of the stand comprising a support member on the mast foot, so as to limit the pivoting, forward and backward, of the front part of the arrowhead relative to the arrow.

  • the front part 21 of the arrow holder 5 has, at its top, a tenon 28 provided with a rear hole 30 for the broaching of the line of tie rods 19 of the counterjib 8, and a front hole 29 for the final broaching of the two parts, front 21 and rear 22, respectively, of the arrowhead 5.

  • the line of tie rods 19 of the jib 8 comprises, at its end front, two connecting rods 86 and 87.

  • the second connecting rod 87 in particular in the form of a yoke, is housed inside the double rod 86, and it is connected to the end of the line of tie rods 19, to the same point as the first connecting rod 86.
  • the center distance of the second connecting rod 87 is slightly lower, for example 2 mm, than that of the double rod 86.
  • the broaching of the counterjib 8 is carried out by connecting the double tie rod 19 at the upper end of the rear part 22 of the jib holder 5 by means of the first connecting rod (double connecting rod) 86, the second connecting rod 87 being on standby.

  • This variant has the advantage, in comparison with the previously described version, to no longer require a very precise realization of the centers of the holes at the tops of the front 21 and rear 22 parts of the arrow-holder 5, therefore to overcome a dimensional constraint.
  • the rotating part 4 of the crane can be dismantled by means of a series of reverse operations from those previously described, separating first the two parts 21 and 22 of the jib holder 5, then by handling on the one hand, the assembly composed of arrow 6, of the front part 21 of the arrow holder 5 and tie rods 13 and 14, and on the other hand the assembly composed of the counterjib 8, the rear part 22 of the jib holder 5 and the double tie 19. Once separated, the two parts 21 and 22 of the arrow holder 5 provide a minimum space requirement, for their transport and storage.
