Definitions

  • the invention relates to an assembly rig for a well pump, which has a riser pipe string made up of several detachably coupled riser pipes, a hollow stand and a drive device detachably attached to the stand.
  • Well pumps are mainly used to supply water to the rural population in developing countries in the arid regions of the world. They are generally operated using muscle power and extract groundwater from depths of up to 100 m. Most of the locations of the well pumps are far away and can only be reached by off-road vehicles.
  • Runnenpumpen for installation, maintenance and repair work on such B it's been necessary to bring heavy lifting to the installation site. This presupposes that appropriately equipped assembly teams, an organization of the necessary operational trips and corresponding financial means are available. Often this is not the case, and therefore in many cases there is no maintenance or repair work on the well pumps.
  • the invention is therefore based on the object of developing a simple, lightweight and inexpensive device which is preferably delivered together with each well pump or group of such pumps and remains at or near the installation site, 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.
  • An assembly rig according to the invention for a certain load-bearing capacity can be made considerably lighter and simpler and, accordingly, easier to transport and easier to set up than hitherto used for comparable purposes with the same lifting height and load-bearing capacity. If the terrain is not too difficult, a man of average strength can carry the entire assembly rig according to the invention on foot for longer distances or transport it by bicycle, so that a single assembly rig can be used in suitable cases for several well pumps that are not too far apart.
  • the required stability of the assembly rig at the installation site results from the fact that the mast on the stand of Pump is supported.
  • 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 the assembly rig according to the invention is installed and used.
  • the lifting device can be, for example, a cable winch or chain winch or a hoist that is commercially available and works with intermittent cable clamping.
  • 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 one upper part of the mast is preferably permanently connected to the deflection device, tension member and lifting device. This prevents the individual parts of the assembly rig from being misused and lost.
  • the non-detachable connection can be made simply by the tensile member passing through the lifting and deflecting device having non-detachable fittings at both ends.
  • the lifting device has a hitch which can be anchored on 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 rig 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 is guided vertically on the mast. As a result, the lifting device anchored to the stand is additionally stabilized so that it cannot oscillate, which would make its handling more difficult and would disrupt 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 mast is preferably held in a head part and a foot part, which are fastened or can be fastened to the head or foot end of the stand.
  • the head part is, for example, a plate which has a hole for inserting the mast and a further fastening point for anchoring the lifting device.
  • the deflection device preferably includes a deflection roller, the radius of which corresponds at least approximately to the distance between the mast and column axis, which is determined by the head and foot part.
  • the transport of the assembly rig according to the invention can be facilitated in that the mast is divided into an upper part, to which the deflection device is attached, and a lower part in the form of a riser pipe. If a well pump is installed, there is usually at least one standpipe left, which can then be used as part of the mast.
  • the tension member has a tap at one end assigned to the stand, to which either the drive device or a Yoke for lifting the tubing string is 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 magazine "World Water” from February 1983.
  • the pump is assigned an assembly rig 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 to a surplus riser pipe 14 including the associated pipe coupling 16.
  • the total height of the mast 34 is greater by at least the height of the stand 20 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 assembly rig 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 which 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 which is formed in the example shown 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 jacket pipe 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 stiff bracket which is fastened to the lifting device and can be attached laterally to the head part 22 such that the lifting device is rigid with the stand 20 via the hitching device and the head part 22 can be coupled.
  • 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, possibly forms a pulley block with several such deflection rollers and also forms a lifting device which can be actuated with muscle power .
