Definitions

  • the invention was designed to facilitate the work of all those bricklayers, electricians, plumbers, painters and other workers who are forced to work at a certain height from the ground.
  • US-A-3731758 describes a standard scaffolding whose framework has four upright rods at the four corners on which to fit the four legs of a similar scaffolding in order to realize a tower of the required height consisting of a number of identical modular scaffoldings, stacked on top of one another.
  • this scaffolding has four fixed wheels at the base of the four upright rods: two of these wheels rotate freely with respect to a vertical axis, the third wheel, which also rotates, is operated by a motor driven steering mechanism, while the last wheel is fixed with respect to its upright rod and driven by an electric motor.
  • the main advantage featured by both these devices is that the worker can move in any directions as necessary while remaining at the same height, so that the worker does not have to return to the ground in order to push the scaffolding every time it needs to be moved in order to continue working at the height in question.
  • the scaffolding according to the invention was designed in order to resolve all the problems and inconveniences - including the one just mentioned - that operators who work at a certain height from the ground encounter, and adds the advantage of a motor driven hoist to the previously mentioned features.
  • the scaffolding consists of a series of identical and stackable components (1) having a rectangular surface and constructed with square section pipes, to form a framework having a square plan at the top of which a platform (2) having perimetral railing and a passage area, is fitted.
  • This framework rests on a base (3), having an identical square plan and fitted with two pairs of wheels opposite to each other, one being the driving pair and the other the steering pair.
  • a pinion by means of which the above driving chain (7) is actually connected, is splined next to one of the two driving wheels (4) and along the connecting shaft (5).
  • this chain is operated by a gear fitted to the shaft of the geared motor, drawn by an adjustable lining clutch which reduces the tractive force allowing the gear to slide in the case of obstacles when the scaffolding is moved.
  • the steering wheels (8) positioned opposite to the driving wheels (4) are fitted under the respective side (9) of the base (3), each being fitted on a axial bearing support allowing them to rotate about a vertical axis.
  • This scaffolding is characterized in that, a platform (14) for transporting objects and people up and down and vice versa, slides vertically along the side of the scaffolding in question.
  • this platform (14) is obtained by means of a cable (18) operated by a winch (19) whose drum is operated by a geared motor having a horizontal axis (20); the geared motor (20) and the winch (19) being positioned on the base (3) of the scaffolding on the same side on which the two driving wheels (4) are fitted, and the cable (18) being wound at the top around a transmission pulley (21) fitted at the top end component (2) of the scaffolding, pivoted on a suitably sturdy cross member (22).

Claims (2)

  1. Echafaudage par éléments, avec base motorisée et élévateur latéral, du type par éléments empilables destinés à la réalisation d'un châssis englobant à son sommet une plate-forme (2) avec garde-fou périmétral et caillebotis, et s'appuyant sur une base conforme (3) équipée de deux paires opposées de roues, l'une des paires étant composée de roues motrices (4), tandis que l'autre paire de roues pivotantes (8); étant prévu que lesdites roues motrices (4) soient montées sur les extrémités latérales d'un côté de la base (3) et reliées entre elles au moyen d'un arbre moteur (5) dont le mouvement est donné dans les deux sens de marche par un moto-réducteur (6), au moyen d'une normale chaîne de transmission (7); étant aussi prévu que les roues pivotantes (8) soient montées, au moyen de supports-roulements axiaux prévus à cet effet sur l'autre côté (9) de la base (3), en position opposée à celles des roues motrices (4) et qu'elles supportent appliquées à leur respectif pivot d'accrochage à la base (3), un bras (10) tourné vers l'interne de ladite base (3) couplé avec une barre transversale (11) parallèle au susdit arbre moteur (5); ladite barre transversale (11) résultant couplée, au moyen d'un balancier (12) prévu à cet effet, à un moto-réducteur à axe vertical (13) qui assure la possibilité de translation alternative sur un plan horizontal, de manière à pouvoir commander le pivotement des deux roues (8); caractérisé en ce que à l'externe d'un des côtés du susdit échafaudage, il y a un chariot élévateur (14) qui glisse en verticale et dont le déplacement est obtenu au moyen d'un câble (18) qui inférieurement est commandé par un treuil (19) dont le tambour est mis en fonction par un moto-réducteur à axe horizontal (20) monté sur la susdite base (3) du même côté sur lequel sont appliquées les roues motrices (4), tandis que supérieurement, ledit câble (18) s'enroule autour d'une poulie de renvoi (21) située sur la plate-forme du sommet (2) de l'échafaudage, ladite poulie étant pivotée de manière opportune sur une traverse (22).
  2. Echafaudage par éléments, avec base motorisée et élévateur latéral, selon la revendication 1), caractérisé en ce que l'élévateur (14) présente, aux respectives extrémités latérales de sa face frontale, deux paires de petites roues (15) ayant axe horizontal et disposées entre elles à 90°, chacune étant destinée à fonctionner en tant que battement et à glisser sur les côtés externes d'une équerre de glissement en forme de "L" (16), montée longitudinalement sur toute la hauteur du côté externe de chacun des montants tubulaires (17) prévus sur le côté du châssis le long duquel se déplace le monte-charges (14).
