Definitions

  • the invention relates to an assembly attachment for installing and removing riser pipes of a well through a hollow stand, with a mast which has a deflection device with a deflection roller at its upper end, and a tension member which is guided over the deflection roller at one end is designed for attaching a riser pipe and at the other end for attaching to a lifting device.
  • Well pumps are often used to supply the rural population with water in developing countries in the arid regions of the world. They are generally operated by muscle power and pump groundwater from depths of up to 100 m. The locations of the well pumps are usually far away and, if at all with land vehicles, can only be reached with off-road vehicles.
  • riser pipes can only be installed and removed through the hollow stand without the risk of jamming and jamming if the mast is held in an inclined position by the associated holding ropes in such a way that the strand of the rope led down to the riser pipe via the deflection roller or other tension member runs exactly along the axis of the hollow stand.
  • the invention is therefore based on the object of developing a simple, lightweight and inexpensive device which is preferably supplied together with each well pump or group of such pumps and remains at or near their installation location, preferably in the care of a person responsible for pump operation, who without special training should be able to set up the device on the well pump when necessary and thereby at least prepare the necessary maintenance or repair work.
  • the object is achieved by an assembly attachment of the type described above, in which the mast is held axially parallel to the stand in a head part and a foot part, which are attached or can be fastened to the head or foot end of the stand, and the radius of the deflection roller is at least approximately corresponds to the distance between the longitudinal axes of the mast and stand.
  • An assembly attachment according to the invention for a certain load capacity can be made lighter and simpler, since the mast is kept almost completely free from bending loads in any position of the tension member. Accordingly, the mounting attachment can be transported more easily and set up more easily than hitherto conventional lifting devices of the same lifting height and load capacity.
  • An average strong man can carry the entire mounting attachment according to the invention on foot over long distances or transport it by bike in not too difficult terrain, so that a single mounting attachment can be used in suitable cases for several well pumps that are not too far apart.
  • the required stability of the mounting attachment at the installation location results from the fact that the mast is supported on the stand of the pump.
  • the stand is designed to be sufficiently strong in any case because of the loads occurring during the operation of the pump in order to withstand the loads that can occur when installing and using the mounting attachment according to the invention.
  • the lifting device can for example be a winch or chain winch or a hoist working with intermittent rope clamping be of common construction.
  • An additional rope can be provided as a lifting device for not too deep well pumps with a correspondingly light riser pipe run, which runs over at least one additional deflection device that can be anchored to the stand and is pulled with muscular strength.
  • At least an upper part of the mast is non-detachably connected to the deflection device, tension member and lifting device.
  • the non-detachable connection can be made simply by the fact that the tension member guided through the lifting and deflecting device has non-detachable fittings at both ends.
  • the lifting device has a hitch that can be anchored to the stand such that the tension member runs into the lifting device at a position diametrically opposite the stand axis with respect to the mast axis.
  • the mast is largely kept free of bending moments when using the assembly attachment according to the invention; it is essentially only subjected to pressure and can accordingly be slim and light.
  • the lifting device is designed as a hoist, it preferably additionally has a guide with which it is guided so as to be vertically displaceable on the mast.
  • the lifting device anchored to the stand is additionally stabilized so that it cannot oscillate, which would make its handling more difficult and would disturb the symmetry of the tension member with respect to the mast axis.
  • the lifting device is designed as a cable or chain winch
  • the hitching device can expediently be rigidly coupled to the stand.
  • the head part is preferably a plate which has a hole for inserting the mast and a further fastening point for anchoring the lifting device.
  • the transport of the mounting attachment according to the invention can be facilitated in that the mast has an upper part to which the deflection device is attached and that a riser is used as the lower part. If a well pump is installed, there is usually at least one riser pipe that can be used as part of the mast.
  • the tension member has a tap at its end assigned to the stand, to which the drive device or a yoke for lifting the riser pipe string can be attached.
  • the well pump has a foundation 10 made of concrete, from which a casing tube 12 extends vertically downwards into a groundwater-bearing layer of earth.
  • the jacket tube 12 encloses, at a radial distance, a riser pipe line from riser pipes 14 which are connected to one another by pipe couplings 16 and are centered in the jacket pipe 12 by star-shaped support rings 18.
  • a stand 20 On the foundation 10 is a stand 20 with a laterally projecting, plate-shaped head part 22 and a plate-shaped foot part 24, which is screwed onto the foundation 10.
  • An intermediate housing 26 is fastened on the head part 22 and has a water outlet 28 and carries a drive device 30.
  • the drive device 30 is a transmission which can be driven with a hand crank 32 and in turn drives a shaft train (not shown) which extends downward through the riser pipe train and is coupled to a helical rotor.
  • the rotor works in a helical stator, which is arranged in the lower end region of the casing tube 12 and can be pulled out through the casing tube together with the riser tubes 14.
  • the well pump can also be designed as a piston pump, for example; in this case, the drive device is designed such that it converts the rotation of a hand crank or swivels of a pump arm into rising and falling piston movements.
  • Such pumps are known, for example, from the World Water magazine from February 1983.
  • the pump is associated with an assembly attachment with a slim, tubular mast 34, which is composed of an upper part 36 and a lower part 38.
  • the lower part 38 is identical in all details with a surplus riser pipe 14 including the associated pipe coupling 16.
  • the total height of the mast 34 is at least by the height of the stand 20 greater than the length of each individual riser pipe 14 including the pipe coupling 16.
  • a deflection device 40 is arranged, which has a deflection roller 42.
  • the axis of rotation of the deflection roller 42 intersects the mast axis 44 and extends in the illustrated, assembled state of the mounting attachment at a right angle to the vertical plane in which the column axis 46 and the mast axis 44 parallel to it lie.
  • the deflection roller 42 has a deflection radius that corresponds to the distance between the two axes 44 and 46.
  • the upper half of the deflection roller 42 is covered with a protective hood 48.
  • a tension member 50 runs over the deflection roller 42, which in the example shown is formed by a rope, but could also be formed by a chain.
  • an annular fitting 52 is fastened, on which a yoke 56 is suspended via a tap 54.
  • the yoke 56 has a central recess 58 which is open at the side and is dimensioned such that the risers 14 can be grasped one after the other below their pipe coupling 16 with the yoke 56 in order to be pulled out of the casing tube 12 or lowered into it.
  • the drive device 30 can be attached to the tap pot 54 for its removal or attachment, for example on two shaft ends.
  • the other strand of the tension member 50 runs through a lifting device 60, which is shown as a commercial hoist with alternating jaw pairs 62, an actuating lever 64 and a brake lever 66.
  • the lifting device 60 has a hitch 68 in the form of a hook and a tubular guide 70 with which it is guided on the lower part 38 of the mast 34 so as to be displaceable in its longitudinal direction.
  • the tension member 50 is led out downward or laterally out of the lifting device 60 and has a further fitting 72 at its end.
  • the lower part 38 of the mast 34 is inserted from above through a circular hole 74 in the head part 22 of the stand 20 and engages in a sleeve-shaped holder 76 which is formed on the foot part 24. As a result, the entire mast 34 is rigidly connected to the stand 20, so that it requires no further support.
  • the head part 22 has a further fastening point 78 in the form of a hole which lies on the same radius starting from the stator axis 46 as the center of the hole 74 which determines the position of the stator axis 46.
  • the center distance of the fastening point 78 from the stator axis 46 is twice as large as the center distance of the hole 74 from the stator axis.
  • a chain 80 extends through the hole 78 and is hooked into the hitch 68 and fixed to the head part 22 of the stand 20 with a bolt 82.
  • the hitching device 68 can have a rigid bracket which is attached to the lifting device and can be attached laterally to the head part 22 such that the lifting device can be rigidly coupled to the stand 20 via the hitching device and the head part 22 is.
  • an additional rope 84 can be attached to the tension member 50, which runs over at least one additional deflection roller 86 anchored to the stand 20, optionally forms a pulley block with several such deflection rollers and likewise forms a lifting device which can be actuated with muscle power.
