Definitions

  • the invention relates to a device for receiving, Converting and storing energy on a vehicle without their own drive, especially railway cars for Bulk goods with one through at least one over one Control cylinder drive controlled working cylinder drive actuatable unloading device, which has a Axle of the vehicle can be charged by means of a wheelset pump hydraulic pressure accumulator with a charge oil flow switch-off device contains, the oil flow after charging of the pressure accumulator by passing it leading return pipe can be drained into an oil tank is.
  • DE-G 91 13 007 shows a cylinder pressure accumulator with a charge oil flow cut-off device.
  • the cylinder is divided into a gas space and an oil space by a flying piston.
  • oil is pumped into the oil space through a pipeline leading into the oil space for the charging oil flow. This is done when used in a hydraulic system on a vehicle not equipped with its own drive, for example a railroad car for bulk goods, with a hydraulically actuated unloading device by a wheel set pump known per se, which pumps continuously while the vehicle is moving.
  • the charging oil flow is passed without pressure through a return pipeline past the pressure accumulator into an oil tank. From this, the oil is taken out for the next loading process.
  • Such a device which during the drive of a self-propelled vehicle and not equipped with its own energy source, absorbs energy via its wheels and transfers it to a fluid system by means of a wheel set pump, stores it there and makes it available via fluid-cylinder drives, generally referred to as working cylinders, is used in transport traffic of bulk goods very advantageous. All that is needed is the control of the working cylinder drive or drives to move the unloading device of the vehicle.
  • a control for a working cylinder which can be acted upon on both sides and can be locked in an end position has become known from DE 42 02 792 C2.
  • This also consists of a pressure medium cylinder drive, which is fed from the same source as the working cylinder.
  • this control must first be switched on manually on the spot, that is, on the vehicle. This requires a lot of personnel. Depending on the type of unloading location, reaching and / or leaving the vehicle is not always safe.
  • the invention is based, for one hydraulically operated unloading device on one a vehicle not equipped with its own drive To create device that is suitable, the hitherto required manual activity on the vehicle to switch on the unloading device by technical means to make replaceable.
  • the invention is based on a device according to DE-G 91 13 007 in connection with a hydraulically actuated known per se Unloading device as mentioned above.
  • a cylinder pressure accumulator 1 is provided as the hydraulic pressure accumulator, in which a flying piston 2 divides the interior into an oil space 3 and a gas space 4 .
  • a wheelset pump 5 which receives its drive from an axle of the vehicle when it is moving, an oil flow is passed from a pressureless oil tank 6 through a pipeline 7 via an indicator 7a with a check valve 8 into the oil chamber 3 of the pressure accumulator 1 .
  • the piston 2 is pressed against the gas space 4 and the gas which is under prestress is compressed therein. Energy is extracted from the locomotion of the vehicle and converted into pressure energy, which is stored in the gas space 4 of the pressure accumulator 1 .
  • Another pipeline 9 leads from the oil chamber 3 via a check valve 10 to the hydraulic system (not shown in the drawing) for opening and closing the unloading device of the vehicle.
  • the charging oil flow pipeline 7 leads past the pressure accumulator 1 through a valve 11 located on the gas-wall end wall of the pressure accumulator 1 , which blocks the flow during the unloading process.
  • the valve 11 is opened by a plunger 12 leading out of the gas space 4 .
  • the oil flow can now flow without pressure past the pressure accumulator 1 to the oil tank 6 through the return pipe 7b .
  • a hydraulic motor 13 is enclosed in the return pipe 7b between the valve 11 on the pressure accumulator 1 and the oil tank 6, which hydraulic motor 13 can be non-positively connected to an electric generator 14 .
  • the current generated by this is stored in a connected power store 15 , from which means (not shown in the drawing) for actuating the valves of a control cylinder drive of the discharge device can be fed.
  • the power store 15 is equipped with a known overcharge protection device which overrides the power generator 14 after charging is complete. Then this runs on the hydraulic motor 13 with no load in the return oil flow, which now flows without pressure into the oil tank 6 .
  • a radio receiver (not shown in the drawing) is connected to the power store 15 and can receive radio signals for controlling the vehicle unloading device via a remote control known per se. It is therefore no longer necessary for an operator to have to work on the vehicle with each unloading operation. An operator can control the opening and closing of the unloading device by radio remote control from an optimal location safely and without significant effort or by passing signaling devices on the way of the vehicle.
  • the arrangement of the hydraulic motor 13 in the return pipe 7b shows that the hydraulic motor 13 can only be supplied with energy for driving the power generator 14 after the pressure accumulator 1 has been fully charged by the wheel set pump 5 .
  • the energy that drives the wheelset pump 5 is therefore never used simultaneously, but always in succession for charging the pressure accumulator 1 and driving the power generator 14 via the hydraulic motor 13 . In this way, the charging of both storage tanks is spread over a longer route and counteracts overloading of the locomotive moving the train.
