Definitions

  • the invention relates to a screwing machine for rail fastening screws, with an internal combustion engine, one with a slip clutch Gearbox and one intended for the rotation of a screw head Drive shaft and a rail carriage for a manual procedure the machine on a track.
  • Another hydraulic screwing machine known from DE 29 43 938 A1 has a screw head which can be acted upon by a hydraulic motor on. Such a screwing machine allows an accurate one Torque limitation, however, is bulky due to the relatively high weight.
  • the object of the present invention is now to create a Screwdriver of the generic type, with only a small amount constructive additional effort and retention of a mechanical drive an exact torque can be transferred to the screw head is.
  • the screwing machine created according to the invention to solve the problem is driven by a hydraulic pump driven by the internal combustion engine, a hydraulic line having a pressure relief valve and one arranged between the slip clutch and the screw head, by means of the hydraulic pump Actuable drive unit used for torque transmission is connected to the drive shaft via a one-way clutch.
  • a screwing machine designed in this way enables relatively little constructive additional effort the combination of the advantageous properties a mechanically and a hydraulically driven machine. So that exists the opportunity to tighten the screwing process in a first stage below the specified torque due to a purely mechanical drive to carry out and in a immediately subsequent second stage Actuating the hydraulic drive unit with the screw exactly to the desired torque. Through the one-way clutch is despite the constant mechanical connection of the hydraulic drive unit with the drive shaft an optional action on the drive shaft possible by the drive motor or by the hydraulic work unit.
  • the training according to the invention has the particular advantage that a simple way of retrofitting existing ones Screwing machines is feasible. In addition, the weight the screwdriver compared to a purely mechanically driven one Execution only slightly increased.
  • a screwing machine 1 for the implementation of all occurring in the track superstructure Screwdriving essentially consists of one with diesel or petrol driven drive motor 2, a transmission 3 with a clutch 4, a drive shaft 5 and a screw head 6 together.
  • the screwing machine 1 is supported a rail undercarriage 7 on a rail 8 of a track 9 and is with Can be moved by hand using a handle 10.
  • One over an angle head 11 positively connected to the drive shaft 5 screw 12 has at its lower end a screwing tool 13 for tightening or loosening rail fastening screws 14.
  • a hydraulic pump 15 can be driven by the drive motor 2 and stands via a schematically indicated hydraulic line 16 with a drive unit 17 in connection.
  • this is hydraulically loadable Drive unit 17 from a perpendicular to a longitudinal axis 18 of the drive shaft 5 and horizontal hydraulic cylinder 19 with a rack 20 slidably mounted in the longitudinal direction thereof is in positive engagement with a rotatable about the longitudinal axis 18 mounted gear 21.
  • This is assigned a one-way clutch 22, a power transmission from the drive unit 17 to the drive shaft 5 only possible if a rotation of the gear 21 in a to Tightening the rail fastening screw 14 is carried out.
  • a pressure gauge 23 is the released by the hydraulic pump 15 and acting on the drive unit 17 hydraulic pressure can be measured and regulated.
  • the screwing tool is used to tighten a rail fastening screw 14 13 placed in a known manner and actuating the clutch 4 set in rotation via the drive shaft 5 by the drive motor 2.
  • the torque that can be achieved as a result of the as a slip clutch trained coupling 4 adjustable and is advantageously just below the desired torque.
