Definitions

  • the present invention relates to an elevator comprising at least one telescopic mast.
  • elevators comprising a platform or a nacelle making it possible to have one or more operators work at a certain height above the ground, for example for the maintenance or repair of building facades, high-rise lampposts, maintenance of hangars, etc.
  • a first type of elevator concerns hydraulic elevators comprising a gondola that can accept one or two people.
  • the elevation is obtained by the movement of mechanically welded arms hinged together and generally controlled by hydraulic cylinders. Besides the fact that they are very expensive, these devices are bulky when folded to the ground.
  • Another type of elevator comprises a working platform animated by a vertical elevation movement obtained by the action of one or more hydraulic cylinders acting on a device of arms articulated together according to the technique known as "of chisel".
  • These devices are heavy and expensive, and have, from a functional point of view, the disadvantage of a significant limitation in height.
  • a third type of elevator comprises a nacelle or working platform fixed to the end of a telescopic central mast, the vertical elevation movement being obtained by deployment of this mast using hydraulic or mechanical means.
  • elevators comprising two telescopic masts arranged at two ends of the working platform, the vertical movement of the platform being obtained by simultaneous deployment or telescoping of the two masts from a single manual or electric winch.
  • the present invention aims to remedy these drawbacks.
  • the elevator it relates to of the type comprising at least one telescopic mast articulated on a substantially horizontal frame near one of its ends around a horizontal axis, the axis of articulation of the mast on the chassis is located in a horizontal plane above the upper plane of the chassis, to allow the platform to be accommodated between the chassis and the mast, when the latter is folded horizontally, the platform remaining associated with each mast when it is horizontal.
  • This elevator has the advantage of being reduced in size and of constituting a complete device not requiring the addition of additional parts for the passage from the folded position to the unfolded position.
  • the fact that in the folded position the masts are above the chassis allows, in addition to the housing of the platform, the housing of other members such as the motor for actuating the masts and the platform. form.
  • This elevator is equipped with means allowing, at first, the pivoting of each mast from its horizontal position to the vertical position, then the deployment of the masts and the movement of the platform along them.
  • the automation of the means of actuation of the masts and of the platform allows a single operator to set up and deploy the elevator at the workplace without other operations than controlling the motorization of the masts and the platform.
  • this elevator comprises several masts, associated with two opposite ends of the platform, the different masts are offset with respect to each other. so as to pivot in parallel planes sufficiently distant from each other, to that the different masts can be juxtaposed in the same horizontal plane in the folded position.
  • each mast is constituted by several telescopic tubular profiles fitted one inside the other, of which that of larger section comprises, on its face facing the middle of the apparatus, two profiles longitudinal forming guide rails for a carriage of the platform and of which that of smaller section, of length greater than that of the other profiles, is equipped, in its projecting part thereof in the nested position of the different profiles, of two rails arranged in the extension of the previous ones, the means for driving the platform and for sliding the elements of each mast being such that, starting from the low position of the platform, the latter is moved upwards up to 'that each carriage is engaged in the rails of the sections of smaller section, before the start of the sliding towards the outside of the different sections constituting the masts.
  • the elevator shown in Figures 1 to 10, comprises a horizontal frame (2) formed by a frame mounted on casters (3).
  • this chassis could be placed on the platform of a vehicle, on a trailer, or be self-propelled depending on the desired use.
  • This chassis carries, at each of its ends, two series of supports (4) offset laterally with respect to each other, each series of supports (4) carrying, at its upper end, an axis (5) serving to the articulation of a mast (6).
  • the axes of articulation (5) of the masts (6) are parallel and arranged in a horizontal plane situated above the chassis (2).
  • each mast is arranged so that when it is in the vertical position, the vertical line passing through its center of gravity is located between the axis of articulation and the center of the 'apparatus, thus facilitating the tilting of the masts towards the horizontal position.
  • Each mast (6) comprises three telescopic parts, each of which consists of two braced elements.
  • Each element (7) has a double U shape, a groove (8) for housing and fixing spacers (9) ensuring its connection with the other element (7), and a groove (10) for guiding an element (7) of immediately lower section, or rollers (12) for the element of smaller section.
  • the rollers (12) belong to a carriage (13) associated with each mast.
  • this carriage includes four braced rollers.
  • One of the spacers of the carriage (13) has two vertical and parallel yokes (14) used for articulation around an axis parallel to the articulation axes (5) of the masts, of a frame (15) carrying the platform (16).
  • a frame (15) carrying the platform (16) As shown in the drawing, it is equipped, in a known manner, with a railing (17), in the areas which are not located opposite the masts.
  • each mast (6) is equipped with a system ensuring its locking in the vertical position.
  • This system comprises two sockets (18) integral with the chassis (2) forming strikes into which penetrate two bolts constituted by two rods (19) slidably mounted longitudinally to the mast in sleeves (20) and each subjected to the action of a spring (22) tending to make the rod (19) protrude from the lower end of the mast.
  • each bolt (19) enters a keeper (18) at the end of the pivoting movement.
  • This locking can only be released manually, for example using a stop (23) holding the bolts in the extended position, as shown in FIG. 7, requiring the operator to descend from the platform to unlock manually the two masts. This avoids that, as a result of a false maneuver, the operator causes the masts to fold back, while he is still on the platform.
  • Each mast is also equipped with a locking system for the various parts constituting it, when they are in the retracted position one inside the other.
  • This system comprises a plate (24) integral with the second part of telescopic elements, comprising a central orifice (25) in which is intended to penetrate a rod (26) integral with the external part of the mast.
  • This rod (26) is integral with a plate (27) connected by two columns (28), parallel to the rod (26), to another plate (29) located on the other side of the plate (24) by relative to the rod (26).
  • a stop (32), associated with each mast, is mounted on the chassis (2), against which the plate (29) comes to bear, when the mast arrives in a vertical position.
  • the action exerted on the plate (29), transmitted by the columns (28), causes the withdrawal of the rod (26) out of the orifice (25) of the plate (24).
  • Such an arrangement is advantageous because allowing the drive system, the operation of which is described below, to act only for the pivoting of the mast, as long as the latter is not in the vertical position.
  • the elevator drive means are constituted by an electric motor (33) located at the lower part of the chassis, comprising an output shaft on which two drums (34) are wedged on which two cables (35) are wound, according to reverse windings, each cable being associated with a mast.
  • Each cable (35) first passes over a pulley (36a) secured to the chassis.
  • the axis of this pulley like the axis of all the other pulleys described below, is parallel to the pivot axis of the mast in question.
