Definitions

  • the invention relates to impact dampers for catching and braking vehicles with buffer elements and spaced-apart, standing on a stand device and longitudinally displaceable cross frame, on the sides of which are arranged scaly overlapping side plates, the buffer elements being plastically deformable during an impact.
  • the invention has for its object to provide an impact damper of the type mentioned, in which the movement of a cross frame caused by an impact can be braked by deformation work.
  • the stand device is designed as a buffer element.
  • the buffer element is designed as a plate construction that is essentially diamond-shaped or kite-shaped in the side view and is open toward the longitudinal side of the impact damper.
  • the diamond corners of the plate construction which run in the transverse direction and each point to the opposite transverse frame, can be flattened to form an impact surface.
  • the buffer element changes its shape to a flat structure, for example the shape of a rectangle, and thereby raises the transverse frame. In this way, the impact energy is consumed by deformation work and lifting work.
  • the plate construction can be reinforced by additional walls that run obliquely and parallel to a diamond wall of the buffer element. It is advantageous that the additional walls on the one hand on a side edge along a horizontal connecting line with a wall of the Buffer element and with the opposite side edge on the cross frame or a vertical partition of the buffer element are attached. Such attachment can be a predetermined breaking attachment.
  • the attachment can be designed as a screw-slip attachment, in which the screw connection enables a relative movement between the additional wall and the intermediate wall when a certain value is exceeded.
  • crash dampers in which at least one rope is guided in the longitudinal direction from an anchorage at the head end of the crash damper to an end support on both sides of the transverse frame, it can be provided that the transverse frame is raised against the tension resistance of the rope.
  • the stand device designed as a buffer element is secured against lifting off on the floor by means of a guide device arranged on the floor. Only the cross frame to which the ropes are attached is raised.
  • the guide device can consist of a rail attached to the floor, which cooperates with a holding device on the buffer element.
  • the rail can have a T-shaped profile, the holding device then consisting of a block with a groove corresponding to the T-shaped profile.
  • the T-profile engages in the groove, so that a positive connection is obtained which, however, allows the entire component, ie the transverse frame including the buffer element, to move in the longitudinal direction.
  • a clamping device is arranged between the cross frame and the standing device, which opposes the relative movement between these two components.
  • This clamping device can consist of a clamping block with wedge-shaped friction inserts which engage a substantially vertical rod which is attached to the base of the buffer element.
  • the clamping block has a recess with walls which narrow downwards in a wedge shape and through which the rod projects.
  • the friction inserts are inserted into a free gap between the rod and the walls of the recess. During an upward movement, the friction inserts are then forced into the gap and cause wedging, which increases the friction work.
  • the brackets for the cables can be pivoted in a vertical plane. This prevents the ropes from kinking.
  • vertical slots are formed in the end support and that the rope end fastening allows the ropes to be pivoted in a vertical direction behind the slots.
  • the crash cushion shown in Fig. 1 consists of a series of spaced transverse frames 1, each carrying side plates 4 on their side frame parts.
  • the side plates 4 overlap from one cross frame to the other so that the crash cushion can telescopically collapse in the event of an impact.
  • the cross frame 1 have a stand device which allows movement of the cross frame on the floor.
  • Ropes 6 are stretched to the side of the cross frame, with one end at the head end of the impact absorber in the floor and the other end are anchored to an end support.
  • the transverse frames have brackets 7 on their lateral frame parts, in which the ropes 6 are guided. At least those brackets that are arranged in the last cross frame before the end support can be pivoted in a vertical plane. However, it is advantageous if all the holders can be pivoted in this way (see FIG. 6).
  • the stand device 5 is designed as a buffer element 2.
  • a buffer element 2 has a substantially diamond-shaped profile in the form of a kite and is designed as a box-like plate construction whose ends facing the side plates 4 are essentially open (cf. FIG. 3).
  • the buffer element 2 deforms upon impact to a flat structure, for example in the form of a rectangle, the long sides of which lie against the cross frame (see FIG. 1, right example).
  • a flat structure for example in the form of a rectangle, the long sides of which lie against the cross frame (see FIG. 1, right example).
  • the transverse frame 1 is raised during this deformation. This lifting takes place against the tension resistance of the lateral guide ropes 6.
  • the mounting of the side plates can be designed so that the lifting movement of the cross frame is not hindered by the side plates;
  • the fastening screws which are used to fix the side plates on the cross frame, can be provided in a groove-like guide on the cross frame, the clamping force being designed so that both the telescopic pushing together of the side plates and the upward movement of the cross frame is made possible.
  • the buffer element 2 is stiffened with additional reinforcements.
  • these reinforcements are formed by additional walls 8, which are only shown on one side in the drawing. However, they can also be arranged in the diamond space opposite. These additional walls run obliquely to the upper roof-shaped side wall of the buffer element and are staggered like lamellae, a vertical intermediate wall 22 projecting downward from the upper diamond edge, on which the frame-side edge 21 'is fixed. The side edge 21 facing away from the frame is welded to the corresponding wall of the buffer element 2.
  • an additional stroke reserve can be created by overlapping additional wall sections 8 ⁇ , which are screwed together, by a screw-and-slide fastening 23 between the additional walls 21 ⁇ and the vertical intermediate wall 22, as a result of which a precisely metered resistance can be obtained.
  • the stand device 5 is secured against being lifted off the floor by means of a guide device 10 arranged on the floor.
  • the guide device 10 consists of a rail 10 'and a holding device 14 fastened to the buffer element 2.
  • the rail has a T-shaped profile on which a block 15 of the holding device 14 is placed.
  • the block 15 has a groove 16, the shape of which corresponds to the T-shaped profile of the rail 10 ⁇ .
  • Block 15 is divided into two, wherein both parts are flanged to the buffer element (see. Fig. 4).
  • the buffer element 2 is equipped with a clamping device 9, which is arranged between the cross frame 1 and the stand device 5 and, in the event of an impact, opposes the upward relative movement between these two components.
  • the clamping device consists of a wedge-shaped friction block 17 ⁇ having clamping block 17.
  • the friction inserts act on a rod 18 fastened to a base point 19 of the buffer element 2.
  • the rod 18 can be suitably, in particular by means of a flange connection, be fastened at the location of the buffer element 2 at which the holding device 14 is also connected to the buffer element.
  • the rod 18 protrudes through a recess 20 in the clamping block 17, the recess being dimensioned such that there is a sufficient gap between the rod and the walls of the recess.
  • the walls of the recess run downwards in a wedge shape, so that the correspondingly designed friction inserts 17, which are inserted into this free gap, wedge during an upward movement of the clamping block between the walls of the recess 20 and the rod 18 and oppose the movement of a frictional force.
  • the rod and the recess can be correspondingly conical.
  • the end support 11 has vertical slots 13 at the attachment point of the cables 6, through which the cables are passed.
  • the rope end attachment behind the end support 11 is designed so that pivoting of the ropes in the vertical slots is possible.
