Definitions

  • the invention relates to a machine for performing track superstructure work, with one by a handle for a manual shift along one Track provided machine frame, supported on a flange roller, a work unit that can be set in motion by an oil motor, an internal combustion engine, and one connected to an oil pump and the oil motor standing hydraulic line.
  • Such a hydraulic screwing machine known from DE 29 43 938 A1 has an adjustable hydraulic pump and a coaxial with a screw head connected, this directly driving oil motor. Using a flow regulator the oil flow is continuously adjustable, with a pressure regulator when reached a desired pressure to avoid torque peaks switches to circulation. When tightening rail screws, the first is done Tightening phase with high turning speed and low moment, the slow one Actuation of the exact end position, however, with high torque. Even though by using the hydraulics advantageously precisely adjustable torques are achievable, the machine is unwieldy due to the relatively high weight.
  • a hydraulically operated suction machine is known from FR 2 650 030 A1, wherein a suction flow is formed by using a fan.
  • a cyclone separator there is a spiral section of a hydraulic line. There is thus the possibility of the outlet from the cyclone separator Suction flow to cool the heated oil.
  • the object of the present invention is to create a machine of the generic type, which by reducing the machine mass with unrestricted Maintaining the hydraulics as the drive medium for the work unit enables improved handling.
  • this object is achieved with a machine as described in the introduction Type solved in that an oil cooler is provided by a portion of the hydraulic line is formed, in which the hydraulic line spirally around a drive shaft the fan attached to the oil pump.
  • a visible in Fig. 1 machine 1 for performing screwing on Track superstructure has a machine frame 2, which has a joint 3 with a Chassis 4 both around a vertical and about a cross-track direction horizontal axis is movably connected.
  • This chassis 4 is over two double-track roller wheels 5 can be rolled on a rail 6 of a track 7.
  • the Rails 6 rest on rib plates 8 and are by means of rail fastening screws 9 connected to sleepers 10.
  • an oil pump 12 attached in the form of a gear pump, which for reasons of balance a longitudinal end of the machine frame 2 are arranged.
  • a vertical one Screw spindle 14 having screw head 13, which is connected via an angular gear 15 connected to a horizontally extending drive shaft 16 of a first oil motor 17 is.
  • the angular gear 15 is equipped with a turning stage, the one Reversing the direction of rotation of the screw 14 allows.
  • One with the machine frame 2 connected handle 18 is used for manual lifting or lowering of the end of the machine frame 2 having the screw head 13 the joint 3 and also for moving the machine 1 to the next screwing point.
  • a second oil motor 19 is provided with a Housing 20 of a gear 21 is connected.
  • This one-stage gearbox 21 has a free wheel 22 arranged coaxially around the drive shaft 16 on, which with a drive pinion 23 of the second oil motor 19 in permanent Is engaged and a rotation of the drive shaft 16 independent of the gear 21 permitted by the first oil motor 17.
  • Both oil motors 17, 19 are via hydraulic lines 34 connected to the oil pump 12. These hydraulic lines settle composed of a working line 24 and a return line 25.
  • a connected to the oil pump 12 section 35 of the return line 25 of the Hydraulic line 34 is spiraled around a fan to form an oil cooler 36 37 led.
  • This fan 37 is, as can be seen in particular in FIG. 2, on a drive shaft 38 of the oil pump 12 attached.
  • the spiral wound and the section 35 forming the oil cooler 36 is cylindrical, the drive shaft 38 coaxial to a longitudinal axis 39 of the cylindrical oil cooler 36 runs.
  • the suction side of the second oil motor is 19 with the working line 24 and thus with the oil pump 12 via a supply line 27 connected in which a connecting valve 28 is arranged.
  • This is as piloted Pressure relief valve 29 formed, which is reached when a predetermined Pressure in the working line 24 is activated or opened.
  • the feed line 27 is connected to the return line 25 via a line 30 which is a pressure control valve 31 includes. This is also pre-controlled and switches when it is reached a predetermined pressure in the supply line 27 to circulation.
  • a circulation valve 32 is also provided between working line 24 and return line 25, with the two oil motors 17, 19 out of operation when the oil pump 12 is running can be taken.
  • the rotation of the screw spindle which is also generally referred to as work unit 40 14 is operated by operating an operating switch 33 and loading the first Oil engine 17 initiated. As soon as the screw is tightened, it happens an increase in the pressure in the working line 24. As soon as a pressure of about 120 bar is reached, the pilot-operated cut-in valve 28 or pressure relief valve opens 29 automatically and the second oil motor 19 becomes parallel to the first oil motor 17 added.
  • a small expansion tank 41 is provided in the hydraulic line 34.
  • a work unit 40 can also be a grinding tool, drill or other tool be used in conjunction with a manually shiftable track construction machine is usable.
