Definitions

  • the invention relates to an insertion and centering device for pipes to be screwed together according to the preamble of claim 1.
  • Such known devices have handles near the open ends of the jaws. When the jaws are closed, the handles form an acute angle and point towards the operator.
  • the closure is designed separately as a latch.
  • the disadvantage is that to operate the closure when opening the handle must be loosened by one of the handles, which can be problematic because of the usually very heavy devices.
  • Another disadvantage is that after opening the jaws, the device can only be removed from the rear, as seen by the operator, for which purpose one hand has to be released and the heavy device then only has to be held with the other hand. If the spatial conditions allow it, the operator can also place the person on the side opposite the lock; then gripping the handles is tedious because they are arranged on the opposite side and point away from the operator. In addition, the operation of the closure is then difficult.
  • the object of the present invention is to improve the device according to the preamble of claim 1 so that handling is facilitated.
  • the particular advantage of the solution according to the invention can be seen in the fact that one handle is simultaneously formed as part of the closure. As a result, the hand change necessary for operating the closure in the known device is dispensed with, so that the device can always be held fully with both hands.
  • the design according to the invention allows the device to be operated from the hinge side in such a way that the device can always be put on from the front and taken away from the front. This makes handling much easier.
  • This device is particularly suitable for pipes with a smaller diameter, and one-man operation of the device is readily possible. For pipes of larger diameter, correspondingly larger devices are required, which can no longer be operated by just one man.
  • a device for handling such pipes with a larger diameter are specified in claim 8.
  • This apparatus is designed so as to b by two people - can be edient, thereby ensuring an also be used in pipes with very large diameters.
  • the particular advantage can be seen in the fact that one handle is designed as part of the closure. This considerably simplifies the operation of the rather heavy device.
  • FIG. 1-3 shows an insertion and centering device 1 for pipes 30, 32 to be screwed together, in particular for use in sinking of pipes.
  • the device has two semi-cylindrical jaws 4, 20 which are connected to one another in an articulated manner by a hinge or a joint 36.
  • annular projections 42 and 44 are formed, each with an annular shoulder 46 and 48 pointing downward. With this shoulder, the device rests on the edge of the sleeve 34 of the pipe 32 in the installed position.
  • the jaws are provided with a funnel-shaped extension 50 or 52 which adjoins the projections.
  • a handle 2 or 24 are arranged approximately in the middle.
  • the handle 2 of the jaw 4 is designed as part of a closure 6.
  • the handle 2 is arranged on the jaw pivotable about an axis 54.
  • a rotatably mounted connecting rod 8 connects the handle 2 to the one free end 14 of a double lever 12 which is pivotable about an axis 56 and is also arranged on the jaw 4.
  • a claw 18 is formed which, in the closed position of the jaws, engages over a tooth 22 arranged on the other jaw 20, as is particularly clearly shown in FIG. 2.
  • the locking device 10 is preferably designed as a self-locking snap device.
  • the handles 2.24 are arranged diametrically to one another.
  • the handle 2 can also be designed to be rotatable about its horizontal axis 26. It is then not the pivoting movement but the rotary movement that is transmitted to the locking device 10, which can also be done, for example, by a Bowden cable (not shown) instead of the connecting rod 8.
  • the components of the closure 6 or the locking device 10 are shown as elements arranged on the jaws.
  • the components of the closure (with the exception, of course, of the handle 2) can, however, also be designed entirely or partially embedded in the jaws (not shown).
  • the insertion and centering device shown in the drawing for pipes to be screwed together takes optimal ergonomic aspects into account.
  • the handles 2 and 24 can of course be off-center, i.e. be arranged diametrically in the closed position, also closer to the hinge 36. In any case, it is ensured by the illustrated and described design that the device can be put on both from the front and can be removed to the front, which makes work considerably easier.
  • FIG. 4 - 7 shows an insertion and centering device 1 'for pipes to be screwed together (not shown), in particular for use in sinking pipes.
  • the device has two semi-cylindrical jaws 2 ', 4' which are connected to one another by a hinge or a joint 6 '.
  • annular projections 12 ', 14' are formed, each with an annular shoulder 16 'or 18' pointing downwards. With this shoulder, the device rests on the edge of the sleeve of a pipe in the installed position.
  • the jaws are provided with a funnel-shaped extension 20 'or 22' adjoining the projections.
  • On the outside of the jaws 2 ', 4' are circumferentially two handles 24 ', 26' or. 28 ', 30' arranged, which are designed as a hand bracket.
  • the hand bracket 30 'of the jaw 4' is designed as part of a closure 32 '.
  • the hand bracket 30 ' is attached to the jaw at its one end 34' so as to be pivotable about an axis 36 '.
  • a claw 40 ' is formed which, in the closed position of the jaws, engages over a tooth 42' arranged on the other jaw 2 ', as can be seen particularly clearly in FIGS. 5 to 7.
  • the closure. 32 ' is preferably designed as a self-locking device.
  • the end 38 'of the hand bracket 30' is passed through a U-shaped or rectangular eyelet 44 'as a guide and to limit the pivoting movement.
  • a compression spring 46 ' is arranged in the eyelet, which prestresses the pivotable hand bracket 30' in the closing direction.
  • the hand bracket 26 'of the other cheek 2' adjacent to the closure 32 ' is also designed to be pivotable, specifically as a closure opening means.
  • the hand bracket 26 ′ like the hand bracket 30 ′, is attached with its one end 48 ′ to the jaw 2 ′ so that it can pivot about a pivot point 50 ′.
  • the other free end 52 'of the hand bracket 26' engages under the outer end or the claw 40 'of the hand bracket 30' in such a way that the hand bracket 30 'is moved from the closed position into the open position by pivoting the hand bracket 26' outward.
  • the end 52 ′ of the hand bracket 26 ′ is also passed through a U-shaped or rectangular eyelet as a guide.
  • a compression spring can also be arranged in this eyelet 54 ', which prestresses the hand bracket 26' in the closing direction of the closure 32 '. Such a spring is not absolutely necessary.
  • FIG. 6 shows a simplified version of the insertion and centering device.
  • the hand strap 26 'according to FIG. 5 is also designed as a fixed strap strap 56', as are the hand straps 24 'and 28'.
  • the device according to FIG. 6 is identical to the device according to FIG. 5. The same components of both devices are therefore provided with the same reference numerals, so that with regard to the further description the description of the embodiment according to FIG. 5 can be referred to.
  • FIG. 7 shows a third embodiment of the insertion and centering device, in which the hand bracket 30 ′ of the devices according to FIGS. 5 and 6 is designed as a spring steel bracket 58 ′.
  • This spring steel bracket 58 ' is fixedly attached to the jaw 4' at its end 60 'and is pretensioned in the closing direction of the closure 32' by its inherent tension.
  • the hand strap adjacent to the closure 32 ′ is also designed as a fixed hand strap 56 ′.
  • this hand strap 56 ′ can also be designed as a spring strap 62 ′ and, like the strap 26 ′ according to FIG. 5, can serve as a closure opening means.
  • the embodiment according to FIG. 7 corresponds to the devices according to FIGS. 5 and 6. Therefore, the components that are identical to the components of the devices according to FIGS. 5 and 6 are provided with the same reference numerals, and it should to avoid unnecessary repetition, reference is made to the further description of FIGS. 5 and 6.
  • the insertion and centering device according to FIGS. 4 to 7 is intended in particular for pipes with a larger diameter. Accordingly, since these devices are heavy, they cannot be operated by one man, but must be operated by two people and struck around the pipe sleeve. In the embodiment according to FIG. 6 , the device can only be opened with the aid of a hand strap 30 ′. In one embodiment of FIG. 5, however, the Device can be opened with either of the two handles 30 'or 26'. Because of the weight of the devices, they are often hung on a rope, and the opening can then be done by a man, always from the side closest to him.
