Definitions

  • the present invention is located in the technical field of fixed or floating bridges and more precisely means for hooking two bridge elements together.
  • the main function of this device is to pick up and drop off a bridge element and requires manual intervention for the positioning of the gripping balls.
  • the centering pins which do not erase may be subject to damage.
  • German patent 1 124 383 describes a device for assembling two bridge elements end to end and requires a manual operation of fitting the locking hooks.
  • German patent 1 809 928 describes an end assembly between two elements whose end face is inclined, by means of pins arranged in front and placed manually. This device has the major drawback of not being able to transmit the loads, the arrangement of the pins in bores of the end face not ensuring an assembly resistant to the passage of loads.
  • French patent 20,242,575 which corresponds to the preamble of claim 1, shows the blunt assembly of two elements locked together by rods perpendicular to the upper surface of the element whose locking is ensured by a part. holding the first element which must pass through the whole of the second element in order to be housed in a hollow cell thereof and this without any means of centering the elements together, which requires extreme precision in positioning the assembly, detrimental to the speed thereof.
  • One of the aims of the present invention is to provide a hooking device making it possible to hold assembled and locked one on the other bridge elements (so-called clapboard assembly) such as gangways, spans, ramps from fixed supports. or floating in order to produce a structure making it possible to clear any type of breach by vehicles, while avoiding the drawbacks presented by the prior devices.
  • bridge elements such as gangways, spans, ramps from fixed supports. or floating in order to produce a structure making it possible to clear any type of breach by vehicles, while avoiding the drawbacks presented by the prior devices.
  • Another object of the invention is to reduce the implementation times of a bridge by the installation of an automatic locking after assembly.
  • the invention also aims to ensure the continuity of the raceway formed by the various assembled elements as well as to allow the assembly of elements all identical and without particularization.
  • Another object of the invention is to allow blunt assembly, that is to say by superimposition of the ends of the elements, either on the upper surface of an element, or on its lower surface depending on the circumstances and this without have to modify or adapt each element according to the chosen positioning.
  • the subject of the invention is therefore an automatic clipping device for clipping two bridge elements either on the upper surface or on the lower surface, the lower bridge element possibly becoming an upper element and vice versa, comprising in combination a centering means and means for attaching the two elements, the attachment means being constituted by at least two retractable pins belonging to a bridge element, situated on axes oblique to the surface of the element, the two pins being able to cooperate automatically with two housings of the second bridge element, and having the same inclination as the pins, relative to the surface of the second element.
  • the two attachment pins of the first element open on the same face of the latter (upper or lower surface) while, according to a second embodiment the first element comprises a first attachment stud opening on its lower surface and a second stud on its upper surface while the second element comprises a first housing on the upper surface and a second on the lower surface to cooperate with the two pins of the first element.
  • a first bridge element comprises at least one row of two retractable pins, each row of pins being arranged along an axis perpendicular to the longitudinal axis of the bridge element, the second element comprising at at least one row of housings able to cooperate with the pins of the first element.
  • the means for centering the two bridge elements consists of a retractable centering finger of the first element situated along an axis perpendicular to the surface of the first element in the highest part of the structure of this element, and able to cooperate with a corresponding housing dant practiced in the end of the second element.
  • the centering finger can be locked for example by means of a movable key belonging to the second bridge element and cooperating with a bore in the centering finger of the first element.
  • the element may also include at least one row of retractable nipples situated on axes oblique to the surface of the element, each row comprising at least one nipple opening onto the lower surface and a nipple opening onto the upper surface of the element and may comprise in combination at least one row of housings arranged at the same inclination as the studs, each row of housings comprising at least one housing opening onto the lower surface and a housing opening onto the upper surface so as to cooperate with the nipples of a second bridge element to be assembled.
  • a bridge element A comprises at each of its ends at least one retractable stud 1 opening onto the upper surface of the element and located in a longitudinal vertical plane relative to the element and on an axis delimiting an angle a with the normal to the upper surface of this element.
  • Element A also includes at least a second retractable stud carried by an axis defining the same angle a with the lower surface of the element on which it opens.
  • the pins 1, 2, 1 ', 2' can be operated by any means, hydraulic, mechanical or electromagnetic.
  • the pins 1, 2 as well as the housings 3 and 4 can be arranged in rows perpendicular to the longitudinal axis, the multiplication of the pins increasing the resistance to assembly forces and reducing the load supported by each locking pin.
  • Each element also includes a centering means which makes it possible to arrange the pins 1 and 2 'opposite their housings 3' and 4.
  • This centering means is constituted by a finger 5 (respectively 5 'for the element B) which can be moved for any means as well as the pins 1 and 2 and which engages in a housing 7' of the second element.
  • the finger 5 can be locked by means of a key 6 shown more precisely in FIG. 3 in section in top view.
  • the key 6 may, according to the alternative embodiment shown in Figure 3, be a fixed key carried by the centering finger 5 and engaging in a keying groove 8 'of the housing 7'.
  • the finger 5 can be pierced with a radial bore and receive after positioning a movable key carried by the second element thus ensuring the locking of the centering.
  • the two elements A and B are laid out at an angle, the upper surface of A supporting the lower surface of B, after having removed the centering finger 5 'from element B.
  • the finger 5' comes into place in its housing 7 by rotation of the upper element until the key 6 'comes into position in the groove 8.
  • the attachment pins are arranged in a chevron symmetrically with respect to a vertical to the surface on which they open.
  • the pins 10 and 11 (respectively 10 ′ and 11 ′) of the same element open onto a single face of the latter (upper surface for element B and lower surface for element A ), which does not affect the interchangeability of the elements or their positioning on the upper or lower surface.
  • the pins 10 and 11 of the same element could be arranged one on the lower surface, the other on the upper surface.
  • the assembly of the device of FIG. 4 is carried out in analogy with those of FIGS. 1 and 2 by starting with the centering of the two elements by means of the centering finger of the element placed in the upper position then positioning of the pins 10 and 11 in their housings 12 'and 13'.
  • nipples 1 and 2 have two main advantages with respect to prior devices with normal nipples. Firstly, they avoid the addition of locking means to keep the elements assembled since it is the combination of two oblique nipples and of opposite directions which ensures the maintenance of the two elements applied. Secondly, they allow better load-carrying capacity of the assembly, by the automatic adjustment of the clearances due to their inclined position, as well as by their number which can be increased according to the type of vehicle having to cross the bridge.
  • the invention therefore applies to the assembly of all types of bridges to which it gives great flexibility of use.
