Definitions

  • the invention relates to a replacement device for a traction battery of a truck.
  • the invention relates to a replacement device for a traction battery of a battery electric forklift truck with a receiving surface on which a traction battery can be set, the changeover device can be used together with the traction battery in a battery compartment of the truck and the changing device has rollers that by lifting means under the receiving surface can be lowered and by the traction battery can be raised together with the changing device so far that the changing device can be moved out of the battery compartment on a road surface rolling out.
  • Battery-powered trucks have traction batteries for power supply, some of which have a considerable weight.
  • the traction battery is placed in a battery compartment and, once unloaded, can be replaced with a supercharged traction battery.
  • the traction batteries In reach trucks, but especially in counterbalanced forklifts, the traction batteries have a significant weight, which may be in the range above a ton.
  • a disadvantage of this prior art is that a complete second truck must be kept. Another disadvantage is that this pallet truck must be handled separately from the truck and a traction battery in the operation. The pallet truck must be parked in a stop position and is needed only for the brief moment of removal of the battery. This is ultimately an unfavorable operation, since when a battery change then the pallet truck must be specially brought and in the case of a general other use in the operation may not be available.
  • the battery drawer are usually mounted vehicle-mounted and can be designed, for example, as a full automatic drawer so that the traction battery is moved on a platform completely laterally out of the vehicle.

  • the stand element may consist of two parallel to a removal direction spaced apart rollers.
  • a hydraulic lifting device for the stand element are also provided and the device can be moved separately from the truck.
  • a disadvantage of this prior art is that it is a complex special construction, with the corresponding costs. Also, the stability when moving the traction battery is not very high, since the rollers only a certain amount Width may have.
  • a generic exchange device for a traction battery is known in which the footprint for the traction battery is formed by a support plate which can be raised by means of a scissor lift mechanism. On the struts of the scissor lift rollers are arranged, with which the changing device stands up on the road surface.
  • the CN 103 192 804 A discloses a battery change trolley with height adjustable in vertical telescopic support feet arranged rollers with which the battery change car stands up on the road surface.

  • the Radarmrollen are each mounted in an at least partially U-shaped longitudinal profile as part of a frame which forms the support surface.
  • These profiles may be arranged with the open side down or may be closed in the bulk box sections that are open only in the area of the Radarmrollen and possibly other components or roles down.
  • the changing device can be designed so that the longitudinal profiles are located in the central region of the downwardly open floor opening in the truck when inserted into the battery compartment and thus optimally the space exploit.
  • the longitudinal profiles result in a high load capacity and rigidity.
  • Such a support surface can be limited to a correspondingly large-sized sheet and results in only a small additional height when a traction battery gets up on the changing device and is placed together with this on the laterally existing areas of a floor panel or support elements in the battery compartment.

  • no separate support of the truck or vehicle is necessary and the changing device can be used regardless of a tire wear, since the lifting of the bottom of the battery compartment or the support areas in the bottom region of the battery compartment, by lifting against the road surface. It can be used for the construction of the changing device on a large scale parts and components of pallet trucks. This results in a cost-effective design that over a wide range of uses up to very high vehicle weights and weights of the traction battery can be used, especially since the known technology from the field of pallet trucks is robust and sustainable.
  • the Radarmrollen can each be mounted at one end of a Radarmhebels, which is mounted in a fulcrum in the longitudinal profile with the other end, wherein by a rotation of the Radarmhebels the Radarmrollen be moved down.
