Definitions

  • the present invention relates to a work platform for working on a roof area of a vehicle, in particular on a roof area of an electrified vehicle, according to the preamble of patent claim 1 and a maintenance facility having at least one work platform according to the preamble of patent claim 15.
  • live parts such as pantographs are provided on the roof area. As long as current is flowing, a worker must be prevented from coming into contact with any of these live parts.
  • the voltage in such vehicles can be over 10,000 V, so that contact with the live parts has serious consequences.
  • the AU2011100718A4 a work platform with two working areas.
  • the platform of the working platform has stationary platform elements that form a working plane and each have a longitudinal extension with two opposite longitudinal sides.
  • a railing runs along each of these longitudinal sides as fall protection and as protection against live components.
  • several movable platform elements are provided, which are arranged below the stationary platform elements and, after a vehicle has driven in, can be displaced from this first position parallel to these stationary platform elements in the direction of the vehicle (second position). In the extended state, the railing is from the free edge of the movable platform elements set back. After ensuring that no more electricity is flowing, individual gates in the railing are unlocked so that the worker can access the roof area of the vehicle.
  • a disadvantage of this known solution is that the railing prevents free work on the working level.
  • a work platform with a work area the platform of the work platform having a stationary platform element.
  • a railing runs along the long sides of the stationary platform element as fall protection and as protection against live components.
  • One of the railings has open sections that allow area-by-area and lockable access to the work area.
  • a movable platform element is provided in the access area, which is arranged below the stationary platform element and, after a vehicle has entered, can be displaced from this first position parallel to these stationary platform elements in the direction of the vehicle (second position). When extended, the railing is set back from the free edge of the movable platform element. After ensuring that the power is off, the access in the railings are unlocked, allowing the worker to access a restricted section of the vehicle's roof area.
  • a disadvantage of this known solution is that the railing also prevents free work on the working level. Furthermore, with this solution, the worker only has a very limited area available for working on the roof area of the vehicle. In addition, on the side of the extended second platform element there is no protection against the worker falling or against falling tools.
  • the RU176334U1 shows a work platform with a pivoting gantry mounted on a stationary platform member. When swung down, the transition allows maintenance work on the front area of a run-in vehicle.
  • a disadvantage of this known solution is that maintenance work on the entire roof area of the vehicle is not possible.
  • a disadvantage of this known solution is that the disassembly and assembly of the railings are complex and time-consuming. There is also a risk that a railing will be dismantled before the power is shut off or while there is still a potential risk of workers falling.
  • the object of the invention is to create a generic work platform and a generic maintenance device which do not have at least one of the aforementioned disadvantages and in particular enable efficient and safe work on a roof area of a vehicle.
  • the working platform according to the invention for working on a roof area of a vehicle in particular on a roof area of an electrified vehicle, comprises at least one platform, the at least one platform having at least one first platform element, which forms a working plane and has a longitudinal extension with two opposite longitudinal sides, and at least has a second platform element, which is arranged along at least one of the longitudinal sides of the at least one first platform element and can be transferred between two positions relative to the at least one first platform element.
  • the at least one second platform element forms a fall protection in a first position and a continuation of the working plane of the at least one first platform element in a second position.
  • the at least one second platform element In the first position, the at least one second platform element is aligned transversely to the working plane spanned by the at least one first platform element. In this first position, the at least one second platform element represents the fall protection and at the same time prevents the workers located on the at least one first platform element from coming into contact with live components, analogous to a railing.
  • the dimension of the at least one second platform element is preferably selected in such a way that it corresponds to the relevant standards transversely to the working plane. For example, in the case of low-voltage electricity, a dimension that corresponds to a railing height of at least 1.10 m is sufficient. In the case of heavy current, on the other hand, a dimension of at least one second Platform element required, which corresponds to a railing height of at least 1.80 m.
  • the at least one second platform element is particularly advantageously aligned in the first position essentially perpendicularly to this working plane, which gives the worker a high sense of security.
  • the at least one second platform element is left in the first position.
  • the at least one second platform element is not moved into its second position until it is certain that these two dangers no longer exist.

This can be used, for example, to implement fall protection that can meet the standards for both low-voltage and high-voltage currents. Furthermore, in the case of an entertainment system with high-voltage current, the space requirement of the at least one second platform element can be reduced in the second position, for example by folding the platform element parts together.
  • the at least one second platform element preferably has at least one free end, with at least one distance bridging device for at least partially bridging a distance between the free end of the at least one second platform element and a vehicle located in the working platform being provided in the area of the free end of the at least one second platform element is.
  • the at least one distance bridging device can be used to ensure that the at least one second platform element can be transferred from one position to the other without risk of damage to the positioned vehicle and at the same time an existing gap between the free end of the at least one second platform element is reduced to a tolerable level Mass is reduced or completely closed. This makes it possible in particular to prevent work equipment, such as tools in particular, from being able to accidentally fall through the gap, which could lead to damage to the vehicle or injure workers located below the working platform.
  • the at least one distance bridging device is advantageously spring-loaded, which means that it enables a gap that may be present to be closed in a simple manner.
