Definitions

  • the present invention relates to a double-lid lock for closing two openings that can be connected to each other any cross-sectional shape, preferably for coupling Containers for pollutants at the bottom opening of a containment, with a cover which can be lifted off by means of a device the bottom opening as the top cover of a double cover system.
  • EP-A-0 586 307 and US-A-2 108 238 are normal Closure cap known that around an axis on an opening be pivoted.
  • US-A-4 932 160 and US-A-1 688 570 vertical lids have become known, connected to a horizontal one Opening can be pivoted. Because this is gravity acts in the lid level, the compressive forces are when placing on the seal in a completely different way than with vertical openings.
  • US-A-3,488,883 is a swivel device has become known for a lid, the one on one Has axis about this pivotable swivel bracket on which the end cover around another, to the pivot axis parallel axis on its side facing away from the opening is articulated tiltable.
  • the object of the present invention is therefore to create a new one Specify double-lid lock at which the end cover in a simpler way for the reasons given vertically in With respect to the seal or lifted out of its seat and in it can be lowered again.
  • the present invention proposes Features before in the characterizing part of the claim 1 are listed. Further advantageous features of the invention are disclosed in the characterizing features of the subclaims.
  • the advantage of the present invention is besides that vertical lifting of the lid especially in that the dimensions the double lid lock due to the possibility of laying the pivot axis directly next to the opening is significantly reduced can be and that the opening any such.
  • B. can have a rectangular or square cross-sectional shape.
  • the double-cover lock serves to open the loading opening 1 in the bottom flange 6 of a base plate 2 of a not shown Containments, in a special application one Work box for handling environmentally harmful substances, by means of to close the so-called double-lid technology.
  • the Feed opening 1 including bottom flange 6 and cover can be round, but also other shapes such as rectangular or square.
  • the two lids are replaced by two externally sealed containers to be connected to one another during the coupling process with mutual sealing their outer sides clamped together.
  • the containers are connected to each other.
  • Both lids will after stapling together in one of the two internally contaminated Containers spent or with a device pivoted away from the opening into the interior, the each other opposite, inner surfaces of both clamped together Always keep the lid uncontaminated.
  • the separation of the Lids from each other are reversed accordingly. This means, after separation from each other, the uncontaminated areas are located the lid on the outside of every container.
  • the double-lid lock here is only the one which is assigned to a container and can be pivoted away Lid of a double-lid lock, considered.
  • a cover here called cover 3 of the containment of such a double lid system over the bottom flange 6 by means of the pivot axis 4 in which is supported in the bearing blocks 5 Swivel direction 7 as a whole swivel away from opening 1 or lowerable into it.
  • the pivot axis 4 is intended for reasons the space economy as close as possible to the opening 1.
  • a clamping device on the flange 6 19 attached with handle 20 with which the closed Cover on the yoke 15 in the closed state in its seal is pressed and held closed.
  • other types of locking devices are also available with a handle with electric, hydraulic or pneumatic drive possible.
  • Two swivel brackets 8 are welded to the swivel axis 4 at a distance, at or below which the cover 3 in relation is tilted to them and hung by the yoke 15 are connected.
  • On the end cover 3 on the The top 12 facing away from the opening 1 has a further two double bearing blocks 9 with rotatable bearing bolts on the axis 11 10 placed on which in turn the swivel bracket 8th are attached.
  • the end cover 3 is thus about the axis 11 in addition to the pivoting about the pivot axis 4 rotatable.
  • the axis 11 is, as already mentioned on the Top 12 or the side of the end cover facing away from the opening 1 3 located.
  • the adjustable tip 14 At the bottom of the swivel bracket 8 are between the Swivel axis 4 and axis 11 one or more spacing screws 13 screwed in, the adjustable tip 14 the Movement of the end cover 3 against the swivel bracket 8 limited. Furthermore, on the underside of the swivel bracket 8 in Area of the cross-beam 15 one or more cylindrical pins 16 attached, which protrude towards cover 3 and on which one Spring 17 of greater length sits with a protrusion. Opposite this Spring 17, the cover 3 has a recess 18 into which the spring protrudes when the cover 3 is in contact with the flange 6.
  • the end cover 3 is with a winch, not shown or another device on the swivel bracket 8 around the Axis 4 swung up on an arc. Since the lid 3 is rotatable about the axis 11 relative to the swivel brackets and thereby changing its position to these, it moves a little until it stops at the tip 14 of the spacer screw 13 and is then carried along. In this position it is swiveled up and so remains in the upper, not shown Swivel position. Swings in the opposite direction when lowering the lid 3 shortly before placing in the opening 1 in horizontal Location, at which moment the spring 17 in the Aus.umg 18 comes to rest and now on the in the seal seated lid presses. Now the lid 3 is back raised, it remains briefly under the travel of the Spring 17 during the vertical lifting, before it then like is pivoted away as described above.
