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 1 124383 describes a device for assembling two bridge elements end to end and requires a manual operation of fitting the locking hooks.
  • the patent FR 1 592501 shows, in one embodiment, spans of amphibious vehicles used independently of the vehicles as follwing bridge elements. However, these spans must be coupled while respecting a coupling direction 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. As a result, 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 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 having to modify or adapt each element according to the chosen positioning.
  • the subject of the invention is therefore a fixed or floating bridge element comprising an automatic device to allow two clap bridge elements to be hooked together, either on the lower surface or on the upper surface, characterized in that the 'lower bridge element can become upper bridge element and vice versa, that the device comprises on each end of each bridge element in combination at least a first flap (2) on the upper surface of the bridge element and at least one second flap (3) on the underside of the element, each flap being hinged at (4) on the bridge element so that it opens opposite the end of the element on which it is arranged, the lower (2) and upper (3) flaps being arranged on each bridge element at equal distance from the front front part of the element and determining between this front front part and their position a free end of the element, the free end of each of the two elements to be assembled venan t lay out, with the upper surface of one against the lower surface of the other, and in combination with the flaps (2) and (3), a means of moving the flaps (6, 9, 10) lower and upper surfaces and locking means (16, 17) of the first flap
  • the combined displacement means of the two flaps of an element is constituted by a hydraulic cylinder whose body is fixed to the internal part of one of the two flaps and whose arm is articulated on the front part of each of the two flaps by means of two connecting rods while the locking means is constituted on the first bridge element by at least one pair of locking finger locks controlled by any suitable means such as electrical, electromagnetic means or hydraulics arranged on each flap of the first element and engaging in corresponding yokes of the second bridge element, so as to make the flaps participate in the inertia of the bridge element in particular by the locking of two flaps located on the stretched or compressed fibers of the element under load, whether for an element used alone or assembled with another element.
  • a bridge element 1 comprises symmetrically at each of its two ends a set of two flaps, 2 and 3 (respectively 2 'and 3') located, the first 2, (2 ') on the upper surface of the element and the second 3 (3') on upper surface.
  • Each component is articulated in 4 on the element 1 so that it opens opposite the end of the element on which it is arranged.
  • the flaps are located to the right of a thinned part 5 of the element so that at rest their outer surface fits into the profile of the element without showing any projecting part as seen in the figure 4.
  • the flaps are made mobile by means of a hydraulic cylinder 6 whose body is integral (but mobile in rotation) with a yoke 7 of one of the two flaps.
  • the cylinder body is articulated on the lower surface flap 3 without this implying any limitation to the invention.
  • the arm 8 of the jack is secured to two rods 9 and 10 mounted free to rotate on yokes 11 and 12 of the upper and lower surfaces.
  • the flaps 2 and 3 comprise centering pins 13 (more clearly visible in FIGS. 5, 6 and 8) which are housed at rest in hollow housings 14 located on the element facing the front face of the flaps, thus that during assembly in housings 15 (FIGS. 1 to 3 and 8) formed in the front part of the free end of the element.
  • the flaps 2 and 3 can be held in position by a locking means constituted by latches carried by the flaps and having a locking finger controlled in any suitable way coming to be positioned in bored yokes of the bridge element.
  • locks 16 are arranged on the lower surface flap and are capable of coming to engage in bores 17 made in the thinned part 5 of the element.
  • locks 18 are carried by the upper surface flap 2 and cooperate with bores 19 of the element.
  • each element includes reamed yokes 20 in which come to engage after assembly either the locks of the lower surface flap, or those of the upper surface flap according to the choice of assembly which has been carried out.
  • the assembly process is then as follows: There are two elements according to the invention so that the free ends which face each other overlap (clapboard mounting).
  • the device being perfectly reversible, it is possible to obtain two symmetrical assemblies as shown in FIGS. 2 and 3.
  • the free end 21 B of the element B is therefore arranged on the end 21 A of the element A.
  • the locks 16 A of the lower surface lock of the element A are then locked in the bores 17 A correspondingly and the locks 18 B of the upper surface shutter of element B in the corresponding bores 19 B.
  • the end 21 B is then engaged on the end 21 A until the centering pin 13 A comes into abutment in the housing 15 B while the yokes 20 A and 20 B come to be placed respectively opposite the latches 18 B and 20 A.
  • the locks 18 B and 20 A are then locked, which secures the two elements A and B.
  • the invention tele described has the advantage of involving the locking means in the transmission of forces to the right of the main souls of the bridge elements and of allowing rapid assembly by means of standard elements which will be arranged as required either upper position or lower position without any adaptation.
  • such a structure allows the composition of bridges of all lengths by placing end to end of several elements, these can also be of different lengths since the only requirement of compatibility of the elements between them lies in the same length of their end free and does not affect the length L of the central part of the bridge element.
