Definitions

  • a similar lifting device is known from DE-C-3 314 051.
  • This device has a coupling part arranged on the load carrier of the hoist, which essentially consists of an eyelet which grips the cable of the submersible motor pump with great play and two coupling hooks with adjustable counterweights or a bracket with an adjustable counterweight.
  • the support part arranged on the submersible pump is formed here by a connecting element provided on its outer edge with a circumferential undercut.
  • the clutch hooks or bracket must be engaged and disengaged when the submersible pump is raised and lowered by adjusting the counterweights accordingly.
  • a pre-tension generated in this way by the counterweights is intended to cause the coupling hooks or bracket to engage behind the undercut when lifting and to disengage the coupling parts when lowering.
  • the lifting device requires relatively few parts because it uses the electrical cable as a guide device.
  • the coupling appears to be very sensitive to dirt.
  • deposits on the connecting element prevent the coupling hook or bracket from engaging properly. This in turn can lead to the submersible pump not being able to be lifted by the lifting device or the submersible pump being released from the device and falling during the lifting process.
  • a device for lowering and lifting a load in which a device connected to a lifting device and along a guide wire Moving eyelet cooperates with a lifting chain in such a way that a slot arranged in the eyelet clamps a special link of the lifting chain.
  • the guide wire also serves as an actuating device for the eyelet when connecting and disconnecting with or from the lifting chain. It is advantageous that the lifting device has only a few, uncomplicated parts. However, since the connection and disconnection of the eyelet from the lifting chain can only be influenced by tightening or loosening the guide wire, when using submersible pumps in flooded shafts it cannot be assumed that they will be positively released and - above all - snapped into place.
  • DE-A-3 122 211 discloses a device of the type mentioned at the outset, in which the load hook to be moved up and down by a lifting device is acted upon by a counterweight connected to it for a notching or notching position before lowering.
  • the counterweight is displaceably and lockably arranged on a guide rod rigidly attached to the load hook, the position of the counterweight determining the pivoting direction of the unloaded load hook.
  • the invention has for its object to provide a less expensive lifting device that is suitable for safe lowering and lifting of submersible pumps that are arranged in shafts or pump sumps with heavily contaminated pumped medium.
  • the means, load hooks and brackets used in the subject matter of the invention for connecting the load carrier to the load represent tried and tested elements of mechanical engineering, the operational safety of which is beyond doubt.
  • the use of two guide ropes and an actuating rope represent an increased effort compared to the previously known devices; it not only ensures the use of the tried-and-tested connecting means, but also precise guidance of the load hook for latching into the bracket attached to the submersible pump.
  • the rest can be done by a positioning device provided as an embodiment of the invention, which corrects any deviations in position of the lifting device shortly before it is placed on the bracket and which, after being placed on it, establishes a positive connection with the bracket, by means of which tilting relative to the bracket even under load , e.g. if the hoist is lowered too far, is prevented.
  • a bracket (2) is arranged on the top of a submersible pump (1).
  • the bracket (2) serves as a supporting part during the lowering or lifting of the submersible pump (1) intended for use in a shaft.
  • a load hook (3) which is connected to a load carrier (4) of a hoist via several intermediate links, is latched under the bracket (2).
  • the intermediate links used here such as a crane hook (5), a ring eyelet (6), a short chain (7) and a shackle (8) are not essential to the invention.
  • they serve to connect the parts of the lifting device designed according to the invention to a conventional lifting device which is also suitable for other purposes.
  • the lifting device according to the invention has, in addition to the bracket (2) and the load hook (3) already mentioned, other parts which cooperate in the fulfillment of the functions mentioned:
  • the load hook (3) which is equipped with a counterweight (9), is rotatably arranged on an axis (10).
  • An actuating cable (11) is attached to the counterweight (9), which leads to the upper level when the submersible pump (1) is lowered.
  • Two guide ropes (12) are attached to the bracket (2), which also lead to the upper level.
  • the guide ropes (12) are enclosed by snap hooks (13) which are attached to the lowerable part of the lifting device.
  • Two positioning claws (14) are attached to the axis (10), and their inner contours engage around the bracket (2) when the load hook (3) is lowered.
  • the opening angle of such an inner contour is so large that positional deviations when it is placed on the bracket (2) are corrected.
  • a positive connection between the upper part of the inner contour of the positioning claws (14) and the outer contour of the bracket (2) causes the lowered part of the lifting device to tilt relative to the bracket (2) even under load, e.g. , if the hoist is lowered too far.
  • the lowering process illustrated in FIGS. 3 to 5 proceeds as follows: After latching the load hook (3) under the bracket (2), the submersible pump (1) is lowered with the aid of a lifting device (not shown). The load hook (3) remains under load during the lowering process and thus in the latching position.
  • the load hook (3) is released when the load carrier (4) is lowered further.
  • the counterweight (9) now moving downwards unlatches the load hook (3) from the bracket (2).
  • the part of the lifting device hanging on the crane hook (5) can now be raised to the upper level, where it is available for further use.
  • the guide ropes (12) are kept on standby in the suspension device (15).
  • the lifting process shown in FIGS. 6 to 8 has the following sequence:
  • the guide ropes (12) are removed from the hanging device (15) and locked into the snap hooks (13) of the lifting device.
  • the part of the lifting device located on the load carrier (4) is then lowered on the tensioned guide ropes (12), the actuating rope (11) being lowered without tension.
  • the submersible pump (1) reaching the end position is recognized when the operating cable (11) no longer shows a downward movement.
  • the operating cable (11) is tensioned from the upper level, whereby the load hook (3) reaches the latching position below the bracket (2).
  • the operating cable (11) must now remain tensioned until the start of the lifting process, i.e. until the load hook (3) is under the load of the bracket (2). Now the securely latched load can be raised to the upper level.
