Definitions

  • the present invention falls within the technical sector of the manufacture of metal structures of tubular longitudinal elements, more specifically, lattice structures. It refers to a manufacturing automation system, specially designed to reduce the consumption of materials and energy, as well as the manufacturing time.
  • the automation of all manufacturing processes improves quality, significantly reduces costs and improves efficiency and sustainability.
  • Lattice structures constructed with tubular longitudinal elements are common and have a wide range of use. These structures are formed with two or more longitudinal tubular elements.
  • Those formed by two elements, whether parallel or convergent and joined together with others of smaller dimensions, are usually used as beams for lights or important loads.
  • Those formed by three parallel longitudinal elements are also used as beams, in tower cranes for example and in pillars.
  • Those formed by more than three elements located at the vertices of a polygon with n sides are generally used as pillars.
  • the longitudinal elements are placed in the manner required and fixed to a surface; the points of connection where the tubes of smaller section must be installed are drawn and the length that each one of them is required to be accurately measured; the tubes are cut in such a way that they are perfectly tangent to the longitudinal elements, that is, to make grafts; they are made a bevel for welding; they are held by provisional points to the longitudinal elements and welded manually.
  • the present invention aims to describe an automated manufacturing facility for the manufacture of lattice structures, of any shape and size, constructed with tubular elements, which solves the following technical problems in an economically viable and technically safe way:
  • the lattice manufacturing equipment claimed herein comprises a series of interrelated elements so that its chain operation results in the automation of the manufacture of lattice structures.
  • a lattice structure either a beam or a pillar, is formed by parallel or convergent longitudinal tubes between which they are placed diagonally or in the form of teeth of sierra, a series of pipes that we call latticework.
  • the lattice structure manufacturing plant has several zones.
  • a first zone is the tube placement zone.
  • This area there are tracks parallel to the crane bridge tracks, on which a series of pillars that have a series of devices to support the pipes distributed along their height are placed vertically.
  • the pillars may advance along the tracks to modify the distance between them and the tube support devices may climb and go down the pillars with the same objective.
  • the pillars and supports are placed.
  • a fully automated crane bridge takes from the tube containers and one by one, the longitudinal tubes that will form the lattice structure. These tubes are placed parallel to the ground and perpendicular to the tracks, in the support devices. Once all the longitudinal tubes are already located, the crane bridge begins to place the lattice tubes in the corresponding supports, so that they are placed between the longitudinal and parallel tubes or convergent to them.
  • the motorized diabolos on which the pipes rest the structure is moved and moved to the manufacturing area, maintaining its geometry.
  • This zone in turn is divided into the zone of union of pipes by head and the zone of forming and welding of lattice tubes.
  • the placed structure advances to the forming and welding area of the lattice tubes.
  • the tubes are supported on pillars with supports identical to those of the installation area but also have hydraulic cylinders that push and compress the lattice tube curving it against the longitudinal tube where, with double arcs of induction automatically approach, weld the lattice tube to the longitudinal.
  • This operation is repeated until more tubes are needed, to increase the length of the structure, which is advancing in the same way, that is, by driving the motorized diabolos located both in the placement area and in the manufacturing area, as the training work and lattice soldier.
  • the lattice and then the longitudinal ones, at that time, from the placement zone new tubes are advanced to the zone of union of the tubes by head. In that area a new tube is taken and welded to the tube that was already in the structure by the end or the head, so that its length is extended. It is relocated to the forming and welding zone and the operations are repeated until the structure is completely finished.
  • the finished structure is moved to a collection area. In that area there are motorized roads, but there are no more pillars.
  • the structure moves transversely to the inspection and painting area. It is a closed area where the welds are checked and they are painted and protected against erosion. At the exit of the inspection and painting area the structure is already completely finished.
  • the system allows to make flat structures formed by two longitudinal elements, parallel or convergent, for beams of great lights and / or loads, triangular structures, formed by three longitudinal ones, or more for pillars or beams and structures of square section formed by any number of longitudinal elements on each face for pillars.
  • This equipment consists of a set of automated devices that interrelate to achieve the proposed purpose of automating the entire manufacturing process, from the collection of materials to the exit of the finished product from the manufacturing line.
  • Figure 1 represents a plant of the automatic manufacturing equipment of lattice structures, of any shape and size.
  • the containers (2) containing the longitudinal tubes (16) and the containers (2 ') containing the tubes to form the lattice (17) arrive to the manufacturing hall by means of a pneumatic lift or omnidirectional rolling system.
  • On the opposite side of the ship (B) are the containers (2 ") that contain the pipes and pieces for the manufacture of piles, object of another invention.
  • All containers (2, 2 ', 2 "), are placed centered with respect to the tracks (1).
  • These tracks (1) belong to a first crane bridge used to place the pipes (16, 17) of the structures and to a second crane bridge, used for the placement of piles inside the lattice pillars.
  • Both crane bridges are the same, so that the breakdown of one of them stops production paralysis. Both crane bridges have space for outdoor parking (C), outside the installation area (A).
  • the crane bridges have a minimum height of 12 m. under magnets and a unit payload capacity of 4,000 Kg. They will have three carriages (14) movable by the bridge and each carriage of a magnet (15) to take the tubes, two of them will take the tube by the ends and the third by the center.
  • the magnets at the ends will have a safety system, which will be inserted inside the tubes so that, in the event that the magnetic fastening system fails, the tubes will never fall.
  • the bridge crane will have a minimum useful light of 16 m.
  • a computer-controlled system receives the static calculations that define the geometry of the lattice structure to be manufactured and drives the crane bridge.
  • the crane bridge takes a longitudinal tube (16) that is horizontal in the container (2) and moves it, maintaining that horizontal position ("lying"), to the placement area, that is, a composition formed by a series of pillars (4) which, as seen in Figure 3, these pillars (4) can be move along some raceways (3) with five being the number of tracks in the preferred embodiment.
  • Figure 4 shows that in each of these pillars (4) there are motorized platforms (13) that can be moved in height by said pillars (4). On the platforms (13) large diabolos (6) are placed on which the longitudinal tubes are supported.
  • both the pillars (4) and the diabolos (6) are placed at the precise distance to place the longitudinal tubes.
  • the crane bridge continues the operation until all the longitudinal tubes are placed.
  • the crane bridge takes the lattice tubes (17) from the container (2 ' ) and places them on the small diabolos (6') located on movable platforms (13) on the pillars (4). Since such a structure is a polygon whose faces are formed by a plurality of longitudinal tubes, joined together by a lattice of smaller section tubes, without having longitudinal or lattice tubes inside, for this reason the inner pillars which support the tubes of the upper face, they only have diabolos at ground level, for the lower face and on the opposite upper face, as shown in Figure 3.
  • telescopic brackets (7) located on vertically movable platforms on the pillars, fold down 90 ° or expand. Putting in a suitable position some diabolos (6 ') for the placement of the lattice tubes of the upper face.
  • the crane bridge places these last tubes and finalizes the placement of all the elements of the structure, which will be placed with the exact geometry.
  • the system thus conceived allows structures with any number of longitudinal elements to be made, simply by placing the number of necessary pillars (4) and diabolos (6, 6 ') and of any dimension, moving the pillars (4) along the ground tracks ( 3) and the diabolos (6, 6 ') by the platforms (13) of the pillars (4), one and the other driven by rack-and-pinion motors and systems, automated by the control system.
  • the pillars (4) are placed on the platforms (13 ') below with joints actuated by rotary actuators that allow a variable angle and therefore enable the creation of flat, triangular or square geometries.
  • the pillars (4) are constituted by individual elements joined together, to adapt their height to the necessary one in each case.
  • the zone of forming and welding of lattice tubes (9), is formed by a set of two tracks (3) with pillars (4) equal to those of the placement area except that the pillars (4) of the zone of formed and welded of lattice tubes (9) which, as seen in figure (5) have telescopic hydraulic pistons (18) and vertical shaft diabolos (19), which push and compress the lattice tube (17) by curving it against the longitudinal tube (16), where with double induction arcs that approach automatically, they weld the lattice tube (17) to the longitudinal one (16).
  • the mode of operation would be as follows: the lattice tubes (17) located between the longitudinal tubes (16) and parallel to them reach the forming and welding zone of lattice tubes (9). Two hydraulic pistons (18) push the lattice tube (17) that is between two longitudinal tubes (16) curving it, until the lattice tube (17) bumps into the corresponding longitudinal tube (16), so that the tube lattice (17) is diagonally and supported on the longitudinal tube (16) with the projected angle. Then double induction arcs approach and weld the contact points.
  • the hydraulic piston (18) maintains the pressure for the programmed cooling time, then retracts and lowers to allow the progress of the already welded structure.
  • the elongated structure is moving towards the soldier zone (9) to form and weld the new lattice tube (17) and as it is finished, it leaves the manufacturing area (9) and passes to the collection area (10) .
  • the collection area (10) consists of a set of parallel tracks (without pillars), equipped with motorized diabolos (11), for the advancement of the structures in the longitudinal direction. They also have rack-and-pinion transmission elements for transverse displacement of the entire structure. The structure that is already completely manufactured moves through this storage area (10) to the inspection and painting area (12).
  • the inspection and painting zone (12) is a closed and protected area where welding inspection is carried out, as well as paint and corrosion protection. Once painted and finished, the structure is taken out to the loading and shipping area or to the assembly area (not shown).
