Definitions

  • the invention relates to a drive device for a boring bar, in particular for Decokinganlagen.
  • This so-called "decoking” is usually carried out with high-pressure water jets, which crush the coke and wash out of the drums.
  • the tool for generating these high-pressure water jets is introduced via a drill string from above into the drum.
  • the present invention is particularly the formation of the drill rod drive and thus also the transition from the water supply to the drill rod.
  • This transition from the water supply to the drill rod is formed in known, generic systems as a one-piece feed.
  • the first, upper end is connected to a flange of the water supply.
  • the second, lower end of the feeder is connected to the flange of the drill rod.
  • This second, lower end is usually mounted in an axial and a radial bearing to allow trouble-free rotation.
  • Water supply, supply and boring bar are connected to each other in such a flush and liquid-tight manner that a supplied at the free end of the drill rod tool for decomposing coke in the operating state is supplied with the required water.
  • the packing rings which are arranged at the transition of stationary and rotating components, wearing parts, which can be replaced at regular intervals. If wear occurs, it shows up at the first end of the feeder, where a liquid-tight connection to the water supply is to be established and at the same time adjacent and rotating parts of the drive device adjoin one another.
  • the packing rings which seal this transition of fixed and rotating components as sealing elements, must be replaced in known installations maintenance-friendly with built-Bohrstangenantrieb in the steel frame of the Decokingstrom.
  • a drive device with a feed which has a first and a second section, allows a faster and error-free change.
  • a second section which connects to the drill rod and shows little signs of wear, remains firmly screwed to the gearbox and boring bar. Faults which can occur due to repeated interventions in these parts of the system are thus reliably avoided.
  • the first section of the feeder is detachable by a simple connection and otherwise securely and fluid tightly connected to the second section.
  • the connection in particular the sealing elements between the first section of the supply and the water supply, which is exposed to wear, need not be changed for the use of a drilling device according to the invention.
  • the type of connection between water supply and supply does not necessarily change. However, now only a compact, complete unit is replaced.
  • a weakening of the drilling device by the division of the supply does not take place, provided that the type of connection between the two sections takes account of the loads occurring. It is particularly preferred to make this detachable connection between the two sections by clamping, as a screw connection or as a flange.
  • a clamping connection preferably provides means for clamping connecting the first and second sections of the feeder together.
  • a threaded fastener provides means for bolting interconnecting the first and second portions of the feeder.
  • the gearbox rotating the feed and boring bar is usually custom made in prior art drilling apparatuses because it was believed that this was a very specialized application requiring special measures in the design and layout of the gearbox.
  • the transmissions are enclosed by an oil-filled housing.
  • the drilling device according to the invention is simplified in its construction by the consistent use of standard components that are cataloged by suppliers, for example.
  • the reliability of the device is usually increased because these components have already been tested in a variety of other applications.
  • the price of the drilling device is advantageously reduced.
  • the supply device 4 with a first connection 6 to the water supply 8 and with a second connection 10 to the boring bar 12 and the drive 14 for the transmission 16, with which the supply 4 and the boring bar 12 in the Operating state are set in rotation.
  • the water supply 8 which is only partially shown here, is usually designed in the manner of a gooseneck. It opens into a flange 18, to which a first portion 20 of the feeder 4 attaches.
  • the connection to the first section 20 is made by a first connection 6.
  • the terminal 6 abuts against the flange 18 with a contact surface 22.
  • a standard seal 24 is provided between the terminal 6 and the flange 18.
  • the terminal 6 is detachably connected to the flange 18 by a screw 26, which is only indicated here.
  • the terminal 6 surrounds sealing packs 32 that wrap around the first section 20.
  • the packs 32 are releasably secured downwardly by a bracket 30 with screws 28.
  • the first portion 20 is connected to the second portion 40 via a clamp 36 which engages the first portion via abutment surfaces 38, 38a.
  • a seal 42 is inserted between the two sections 20, 40.
  • the clamp 36 rests against the second section 40 via abutment surfaces 44, 44a.
  • the sections 20, 40 are designed plan on the mutually facing surfaces 46, 46a and have on the outer periphery only the bearing surfaces 38, 38a and 44, 44a described. The production, assembly and disassembly of the first section 20 thus require little effort and time.
  • the packs 32 are worn out they must be replaced.
  • a structural unit composed of the first section 20 the packs 32 and the connection 6 is removed from the drive device 2 after the clamp 36 has been loosened and the connection 6 has been released.
  • the terminal 36 and the terminal 6 are closed again sealingly.
  • the drive device 2 is ready for use again after a short standstill.
  • the second portion 40 is integrally formed with the terminal 10, to which the gear 16 attaches.
  • Another component of the terminal 10 is the flange 48 to which the boring bar 12 is screwed.
  • the screw 50 is only hinted at.
  • the circumferential surface 52 of the connection 10, that is to say the end of the second section 40 facing the drill rod 12, is designed as an outer toothed ring. With this outer sprocket 52 is a gear 54 is engaged, that is set in the operating state by the drive 14 in rotation.
  • the drive 14 has a motor 56. In the present case, it is an electric motor. But it can also be used hydraulic or pneumatic motors.
  • the motor 56 is followed by a gear 58, whose output gear 60 is engaged with the gear 54 in engagement.
  • the outer sprocket 52, the gear 54 and the output gear 60 form the gear 16.
  • the outer sprocket 52 and the gears 54 and 60 are formed as an open, greased gear 16.
  • a closed gear housing is not required and thus eliminates the need to use large amounts of gear oil.
  • the inventively proposed solution of the open transmission 16 is particularly simple and low maintenance.
  • there is the advantage that the outer ring gear 52 no longer needs to be rebuilt for each feed 4, which is to change regularly as a wearing part.
  • the components numbered 54, 56, 58 and 60 are all standard components cataloged by suppliers and have been tested in numerous other applications.
  • a thrust bearing 62 and a radial bearing 64 are arranged. These bearings 62 and 64 absorb the loads introduced by the gear 16 into the drilling device 2 and the dead weight of the drilling device 2 and ensure a smooth rotation of the drilling device 2 in the operating state.
  • the drilling device 2 In order to cover the supply 4 rotating in the operating state, the drilling device 2 has a lantern 66, which represents the connection from the water supply 8 to the transmission unit 16. About the lantern 66 of the drill rod drive is mounted and held. The lantern 66 is easy to assemble and disassemble because it always has to be removed to change the first section 20 of the feeder 4. It has a mounting window in the area of the packs 32, so that complete safety of the operating personnel is ensured when the condition of the packs 32-and thus the extent of signs of wear-is to be controlled, if necessary in the immediate vicinity of rotating high-pressure components ,
