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 deterioration.
  • German patent n ° 1 124 383 describes a device for assembling two bridge elements end to end and requires a manual operation of fitting the locking hooks.
  • French patent No. 1,592,501 shows, in one embodiment, spans of amphibious vehicles used independently of the vehicles as floating bridge elements.
  • these spans must be coupled respecting a direction of coupling since only one end of the span has a coupling element on its upper part while the other end has a coupling element on its lower part.
  • the attachment of two elements is complicated since if an element is presented upside down, it must first be turned over before it can be hung on a second element.
  • 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 (assembly called clapboard) such as: gangways, spans, ramps from supports fixed 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 as: gangways, spans, ramps from supports fixed 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 superposition of the ends of the elements, either on the upper surface of an element, or on its upper surface depending on the circumstances and this, without having to modify or adapt each element according to the chosen positioning.
  • the subject of the invention is therefore an automatic device for the lap joint assembly of two floating bridge elements on the lower or upper surface the lower bridge element which can become an upper element and vice versa by means of locking fingers characterized in that a first bridge element comprises a transverse assembly of movable fingers from a first position where they are erased in the body of the bridge element, towards two second positions where the fingers protrude either on the lower surface or on the upper surface and in that the second bridge element has bores opening right through on its lower surface and on its upper surface, intended to receive the centering fingers of the first element and in combination a set of latches to block the fingers of the first element in the assembly position, and in that the movable fingers of the first element are integral with a shaft perpendicular to the longitudinal axis of the bridge element and movable in rotation under the action of a motor to bring the fingers from their first position to one of the two locking positions.
  • the latches of the second element are arranged inside the section of the bridge element in such a way that the locking pins pass, after assembly, through the bores made in the centering fingers.
  • the centering fingers have their frustoconical end, the bores of the second element having a biconical shape flared towards the upper surface and the lower surface to promote centering.
  • the invention also relates to a bridge element comprising an assembly device as described above and comprising at one of its ends at least one set of centering fingers disposed perpendicular to its longitudinal axis and at least at its opposite end. a set of bores opening right through the lower surface and the upper surface of the element.
  • Figure 1 a longitudinal section of the end mite of two assembled bridge elements and including two variants of shape of the centering fingers.
  • FIG. 2 two half-sections along AA and BB of FIG. 1 perpendicular to the longitudinal axis of the elements being assembled and showing the two variants of FIG. 1.
  • the two elements C and D are arranged in the blink of an eye
  • the element C comprises two rows of fingers 1 and 2 arranged along an axis perpendicular to the longitudinal axis of the bridge elements.
  • the centering and locking fingers 1 and 2 are carried by two shafts 3 and 4 mounted on bearings 3 'and 4' in the core of the element C and made mobile in rotation by means of motors 5 and 6 controlled by any appropriate means.
  • the motors 5 and 6 can have a double direction of rotation or have a reverse gear on the output shaft so that the fingers 1 and 2 can move from their rest position 7 inside the elements C and D to an assembly position, either on the lower surface as shown in Figure 1 in solid lines fingers 1 and 2 or on the upper surface (position 1 'and 2' shown in broken lines) for a reverse assembly of elements C and D.
  • the fingers 1 are provided with bores 8 cooperating with the locks of the element D which will be described later and the fingers 2 in an alternative embodiment have two bores 9 and 10.
  • Element D has two rows of latches 11 and 12 cooperating with fingers 1 and 2. These latches have either a locking pin 13 (for the latches 11) or two locking pins 14 and 15 (for the latches 12) which can be operated automatically by any appropriate means.
  • the locks are arranged in such a way that they open into bores 16 and 17 intended to receive the fingers 1 and 2.
  • the bores 16 will be cylindrical and will include a centering chamfer 18 or biconical (bores 17) so as to ensure perfect positioning of the elements in relation to the other.
  • the fingers 1 and 2 are actuated in the proper direction according to the positioning chosen for the elements.
  • the clapboard elements are then placed, fingers 1 and 2 ensuring the correct centering of the spans.
  • the latches 11 and 12 are actuated.
  • the fingers 13, 14 and 15 are then positioned in the bores 8, 9 and 10 thus ensuring the maintenance of the assembly of the two elements.
  • the fingers 13, 14 and 15 can be suitably sized so that during locking, their length is large enough to pass through the fingers 1 and 2 and rest in bearings 19, 20 and 21 so as to participate in the resistance to the forces , the span itself.
  • a bridge element according to the invention may comprise at one of its ends one or more rows of centering fingers 1 or / and 2 while its other end will include latches 11 or / and 12, the only mounting requirement being to have the same number of rows of locks as corresponding fingers.
  • the invention therefore advantageously applies to the production of bridges of all lengths.
