Definitions

  • the present invention relates to a vehicle and/or a trailer for a vehicle with a platform for bridge inspection.
  • the technical area is platforms for the inspection of bridges, especially the inspection of bridges in their lower part.
  • a vehicle is known as a chassis, especially for the inspection of bridges in the lower area.
  • This chassis comprises an axle assembly with at least one axle equipped with running wheels and a pressure-operated device for raising and lowering the chassis.
  • the axle assembly is dampened by pistons.
  • the chassis can be moved from a first position in which the shock absorber is active to a second, lower position in which the chassis rests undamped on the axle supports. When the chassis is lowered, an additional wheel comes into contact with the road surface and bears part of the total load on the axles.
  • An Italian patent application VE97A000041 discloses a device for inspecting the underside of bridges, comprising a first fifth wheel, a tower mounted on the first fifth wheel and an articulated support arm of a second fifth wheel carrying an articulated arm system provided at the end with a passenger carrier, wherein the second fifth wheel is provided with an inclination sensor which controls means for ensuring the horizontality of the second fifth wheel when the angle formed by its support arm with the tower changes.
  • EP0464062 also describes a similar device as EP0454709 .
  • WO2013098590 discloses equipment for the inspection of metal supports of railway bridges and in particular of lattice switches, wherein a bimodal railway vehicle can travel along the tracks of a railway line and comprises a first equipment unit with mechanisms for starting, a second equipment unit acting as a storage rack and allowing the assembly of bolts along the bridge, and a third equipment unit comprising the actual working equipment that can be transferred to the previously assembled rails; the advance mechanisms of the equipment units consist essentially of double-extended crossbeams, the mobile extension of the crossbeams carrying a first carriage sliding on a rack on the rails and carrying a guide frame on which a second carriage with the storage or working equipment moves.
  • the EP0 865 539 describes a device for inspecting bridges, advantageously the lower part of Bridges in which a working platform is attached to the frame and the arm carrying the platform can be supported on the bridge and the frame is height adjustable at least in its outer part.
  • the chassis comprises at least two parts, wherein a first chassis part has an axle with at least two wheels and the first chassis part carries a fifth wheel rotatable about an axis of rotation, which wheel carries an inspection platform connected via a support structure, that the inspection platform can be positioned under a bridge and that at least one extendable piston between the fifth wheel and the first frame part can align the fifth wheel with respect to a horizontal axis to the first frame part and that the first frame part is connected to the second frame part by a rotatable connection about a horizontal axis parallel to the first frame part and that this connection has a sensor and that the extendable piston according to the data recorded by the sensor.
  • These pistons can be used to compensate for a difference in the level of the road surface, for example.
  • Means and persons can be positioned on the inspection platform; in a preferred embodiment, means for operating the vehicle can also be located on the inspection platform.
  • the first frame part is connected to the second frame part by means of a connecting bolt and the second frame part carries a counterweight to the platform which is rotatably arranged relative to the second frame part by means of a fifth wheel coupling, and a sensor is arranged on a connecting bolt and by means of this sensor the pistons are adjusted to level the fifth wheel coupling which carries the platform relative to the first frame part.
  • This design allows the platform to be leveled even when the vehicle and/or trailer with the platform is moved for bridge inspection.
  • the inspection platform remains parallel to the road and/or the transshipment area to be inspected, which facilitates the inspection.
  • the road can also consist of tracks, for example.
  • FIG. 1 shows with the reference number 100 a vehicle with a bridge inspection platform, in which only the fifth wheel 114 supporting the inspection platform (not shown) is shown.
  • the vehicle 100 has a chassis 110, which consists of a first part 111 and a second part 112.
  • the fifth wheel coupling 114 is connected to the first chassis part 111 so as to be pivotable about an axis 113.
  • the fifth wheel coupling 114 can be adjusted relative to the first chassis part 111 by means of at least one piston 115. In this way, the inclination of the fifth wheel coupling 114 relative to the first frame part 111, which supports the inspection platform 203, can be adjusted.
  • the first frame part 111 advantageously has a pendulum axle 116 with advantageously four hydraulically driven wheels.
  • the first frame part 111 is connected to the second frame part 112 at the opposite end of the fifth wheel position 114.
  • the connection is made via a connecting bolt 117.
  • the distance between the bolt 117 and the fifth wheel 114 can be considered as a lever to more easily balance the forces and/or moments between the first frame part 111, which supports the structure and the inspection platform 203, and the second frame part 112, which supports the counterweight 201.
  • the pin(s) 117 By connecting the pin(s) 117, the inclination of the first frame part 111 can be detected like the arms of a wheelbarrow. This connection allows the fifth wheel coupling 114 controlled while the inspection platform 203 connected to the fifth wheel 114 is kept level with respect to the road surface.
  • a sensor can be attached to the bolt(s) 117, which detects the forces caused by the height difference and, based on this detected data, aligns the piston(s) 115 so that the fifth wheel coupling 114 levels the height differences.
  • This leveling can also take place while the vehicle is moving, with the inspection platform 100 moving on the road surface and/or, for example, on the tracks of a railway line.
  • This system compensates for unevenness or inclinations of the roadway, which can have a strong effect on the inspection platform 203, which is positioned under the bridge by means of a structure 202, e.g. an articulated arm. Due to the long extension of this arm 202, the resulting forces and moments that the frame 110 of the bridge inspection vehicle 100 has to absorb can be very high.
  • the counterweight 201 which is arranged during the bridge inspection when the bridge inspection platform is in working position on the opposite side of the inspection platform 203.
  • the fifth wheel coupling 114 is locked by means of a locking cylinder to prevent accidental To prevent displacement during the journey to the bridge to be tested.
  • the first part of the chassis 111 which is only connected via the connecting bolts 117 to the second part of the chassis 112, which is firmly connected to the vehicle chassis, e.g. in the case of trucks.
  • the fifth wheel coupling 114 is constantly monitored and pivoted during the inspection by an electronic system that receives data from the sensor mounted on the connecting bolt(s) 117 in order to ensure the stability of the system at all times, which is particularly important since there are people on the inspection platform and movement or capsizing of the vehicle would have fatal consequences.
  • the wheels connected to the pendulum axle 116 have no contact with the roadway during the journey to the bridge, but are only lowered before the inspection platform 203 is retracted by means of a hydraulic system, e.g. a lifting/lowering piston.
  • the pendulum axle 116 advantageously has two wheels on each side to ensure optimum vehicle stability.
  • the described vehicle 100 with inspection platform can compensate for height differences of up to +-13°.
  • a leveling/sensor for detecting the inclination can be provided on the first frame part in order to System to assist in leveling the fifth wheel coupling 114.
  • the inspection platform 203 may also be provided with a spirit level/sensor for measuring inclination. This may also serve to keep the system level.
  • a system for measuring forces and/or moments may be arranged between the platform and the orientation structure 202. This ensures that the inspection platform 203 is not overloaded and that the orientation of the fifth wheel is facilitated by the data obtained.
