Definitions

  • the present invention relates to a method for mounting of the tower crane jib tie rods, and a device for implementing this method.
  • This invention finds its application in the assembly of tie rods of the distributing arrow and the counter-arrow associated, constituting support for counterweights, cranes to especially high capacity lathe, used on building construction sites and works public.
  • Such tower cranes are generally rotating from the top, and have a fixed height mast adjustable by means of additional mast elements.
  • the distributing boom of such a tower crane usually has a shaped cross section isosceles triangle.
  • the top of the triangular section corresponds to an upper member of the boom, while that the two corners of the base of this section triangular correspond to two lower members, which form a raceway for a carriage load distribution.
  • This distributing arrow is essentially made up of arrow elements successive, aligned and assembled to each other at means of pin axes arranged at the ends respective of the upper chord and the chords of these boom elements.
  • tie rods restraint also referred to hereinafter more simply as "tie rods”, which are each formed of several parts assembled together, end to end, at means of pin axes mounted perpendicular to the vertical median plane of the arrow.
  • the front end of the or of each tie is linked by articulation, also to the by means of a pin axis perpendicular to the median plane of the arrow, at a point on the upper chord of the arrow.
  • the arrow elements are aligned and assembled together on the ground, the tie rods also being assembled by their front ends to the elements of corresponding arrow, these tie rods initially resting on the upper chord, facing the boom foot element. Then the boom is equipped slings for lifting with an auxiliary machine assembly, such as a mobile crane. At the end of lifting, the rear articulation of the boom foot is presented and embossed on the front face of the masthead, designated also as an arrowhead.
  • the arrow being held in position by the mounting machine, makes a reeving on site between the free end of each tie rod and its fixing point at the top of the masthead.
  • the crane lifting winch or of a cable puller, we pull on the free strand of hauling until a pinout can be made the initially free end of the tie on the top of the masthead.
  • the hauling operation is carried out here in height, and requires the intervention of several assemblers operating in difficult and arduous working conditions, especially in case of wind or other bad weather.
  • the brace is assembled in one analogous to that of the distributing arrow, and therefore has the same disadvantages.
  • the craft assembly assistant is immobilized during all this time, this machine is generally rented at a high cost.
  • auxiliary mounting device to raise the boom and its tie rods around the joint arrowhead, until you can perform a pinout between the free end of each tie rod waiting on the arrow foot, on the one hand, and the end a corresponding connecting piece or "strap", in waiting at the top of the masthead, on the other hand.
  • the pinout being carried out, the arrow is still lowered to using the auxiliary lifting device, until the tie rods are aligned and tensioned.
  • German utility model N ° 87.09267 provides a single haul, having only part fixed and mobile part, applied to a jib crane liftable, where the arrow line is active in work, and the hauling is "working".
  • This device therefore does not concern jib cranes distributor, with line of fixed jib tie rods job. So, this is the arrow lifting haul which is used here for the alignment of the tie rods during the mounting. In addition, this hauling has no use for the mounting the jib.
  • German patent application N ° 33.07.892 relates to a low capacity tower crane, in which a single haul serves to raise the arrow and the arrows, not to align the tie rods.
  • British patent N ° 965,025 relates to him also low capacity cranes, in which the hauling is used to raise the mast of the crane, not to align the arrow rods. In addition, it is a hauling which is not pre-existing on the crane.
  • the present invention provides a solution to difficulties previously outlined, providing a method for mounting the tie rods of the crane jibs tower, and a device for implementing this process, which apply to all types of tower cranes but especially high capacity tower cranes, whose arrows are equipped with several tie rods, the process and the proposed device for mounting quickly, easily and securely for the staff.
  • the strap used for mounting the tie rod of the counter-arrow is formed by the front part of this tie, and is thus an "active" ramp.
  • the device according to the invention for setting work of the assembly process defined above includes, in addition to the aforementioned mounting straps, a set of hauling, between a mounting winch ensuring motorization of a mounting cable, a fixed part located successively on the side of the arrow for mounting the pulling from the jib, then from the jib side for mounting the boom tie rod (s), and a movable part located successively on the opposite side, all the elements of the haulage system being carried by the single head of mast, the parts mentioned above being constituted by at least one pulley carried by the mounting strap of the tie rod counter-deflection, and at least one other pulley carried by the mounting strap of the boom tie (s).
  • the device thus comprises a cable circuit closed, made in the factory, with two moving parts which are alternately used. More specifically, the moving part on the jib side is first used, while the moving part on the boom side is immobilized (ex works), for mounting the counter-arrow; then, after mounting the jib, the moving part on the jib side is immobilized, and the moving part is used on the boom side for mounting of the arrow.
  • the motorized mounting cable runs successively, from the assembly winch arranged at inside the base of the masthead, on a first pulley which is arranged at the top of the masthead and whose axis of rotation is perpendicular to the median plane vertical of the arrow and the counter-arrow, on a second pulley mounted on the side of the jib at one end of a lifting beam articulated at the top of the head mast and resting on the mast head, the axis of rotation of the second pulley being parallel to that of the first pulley, on a third pulley mounted on the strap of mounting of the provisionally fixed jib tie rod on the rear face of the mast head, the axis of rotation of the third pulley being orthogonal to that of the second pulley, then on a fourth pulley mounted coaxially with the second pulley by forming a haulage two strands for mounting the tie bar tie rod, and finally on a set of pulleys forming
  • multiple hauling is carried out between a first series of coaxial pulleys arranged at the other end of the lifter articulated at the top of the masthead, pulleys whose common axis of rotation is perpendicular to the vertical median plane of the arrow and the jib, and a second series of pulleys also coaxial arranged at the upper end of the mounting strap of the boom tie rod (s), the common axis of rotation of the latter pulleys being also perpendicular to the vertical median plane of the arrow and counter-arrow.
  • tie rods are interconnected by their last free end element, by means of a sling in constant length cable.
  • the tie rod (s) of the arrow are pinned on the top of the masthead through a pending connecting piece position to receive the free end elements said tie rods.
  • the length of the sling connecting the elements free end of the tie rods is determined in such a way that at the end of assembly, the ends free of all tie rods can be stapled directly on said connecting piece waiting at top of the mast.
