Definitions
- Double-lid lock for closing two openings that can be connected to each other
- the present invention relates to a double-lid lock for closing two openings of any cross-sectional shape that can be connected to one another, preferably for coupling containers for pollutants to the bottom opening of a containment, with a closing lid of the bottom opening, which can be lifted off by means of a device, as the top lid of a double-lid system.
- guide cylinders are required to lift the sealing cover in order to be able to lift the sealing cover vertically from the base plate out of its seal before it is pivoted away on a circular path by a pivoting arm.
- This sequence of movements is necessary, on the one hand, to prevent the sealing cover from tilting in the flange and, on the other hand, to prevent the seal from being destroyed by lateral rubbing, especially when the pivot axis must be close to the cover for spatial reasons.
- the object of the present invention is therefore to provide a new double-cover lock in which the end cover can be lifted vertically with respect to the seal or from its seat and lowered again in a simpler manner for the reasons given.
- the present invention proposes the features which are stated in the characterizing part of patent claim 1. Further advantageous features of the invention are disclosed in the characterizing features of the subclaims.
- the advantage of the present invention in addition to the exactly vertical lifting of the cover, lies above all in the fact that the dimensions of the double-cover lock are possible due to the possibility of being laid the pivot axis right next to the opening can be significantly reduced and that the opening any such.
- B. may have a rectangular or square cross-sectional shape.
- 1 is a plan view of a double-lid lock with a round lid as an exemplary embodiment, but rectangular, square or other polygonal shapes of the opening and the lid are also possible,
- FIGS. 1 and 2 shows a section along AA of FIGS. 1 and
- FIG. 3 is a view in the direction B of FIG. 1st
- the double-cover lock serves to close the loading opening 1 in the bottom flange 6 of a base plate 2 of a containment (not shown in more detail), in a special application case of a work box for handling substances which are harmful to the environment, by means of the so-called double-cover technology.
- the loading opening 1 including the base flange 6 and cover can be round, but can also have other shapes such as rectangular or square.
- the two lids are clamped together by two containers which are to be connected to one another and are sealed to the outside during the coupling process, with their outer sides being mutually sealed.
- the containers are connected to each other.
- both lids are placed together in one of the two internally contaminated containers or swiveled away from the opening into the interior with a device, the mutually opposing inner surfaces of both lidded lids always remaining uncontaminated.
- the separation of the lids from one another is accordingly reversed. This means, after separation from one another, the uncontaminated surfaces of the lids are now on the outside of each container.
- the double-cover lock here, however, only the cover of a double-cover lock that is assigned to the container and can be swung away is considered.
- the one, here called end cover 3 of the containment, of such a double cover system is pivoted above the base flange 6 by means of the pivot axis 4 mounted in the bearing blocks 5 in the pivoting direction 7 as a whole out of the opening 1 or into it lowerable.
- the pivot axis 4 should lie as close as possible to the opening 1.
- a clamping device 19 with a handle 20 is fastened on the flange 6, with which the closed cover on the yoke 15 is pressed into its seal and locked in the closed state.
- other types of closing devices with electric, hydraulic or pneumatic drives are also possible.
- Two swivel brackets 8 are welded to the swivel axis 4 at a distance, on or under which the end cover 3 is suspended in relation to them and which are connected by the yoke 15.
- two further double bearing blocks 9 with rotatable bearing bolts 10 passing through the axis 11 are placed, on which in turn the swivel brackets 8 are fastened.
- the end cover 3 can thus be tilted or rotated about the axis 11 in addition to the pivoting about the pivot axis 4.
- the axis 11 is, as already mentioned on the Upper side 12 or the side of the end cover 3 facing away from the opening 1.
- one or more spacer screws 13 are screwed in between the swivel axis 4 and the axis 11, the adjustable tip 14 of which limits the movement of the end cover 3 against the swivel bracket 8.
- one or more cylindrical pins 16 are fastened to the underside of the swivel bracket 8 in the region of the crossbar 15 and project in the direction of the cover 3 and on which a spring 17 of greater length sits with a projection.
- 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 pivoted up with a winch, not shown, or another device on the swivel brackets 8 about the axis 4 on a circular arc. Since the cover 3 can be rotated about the axis 11 with respect to the swivel brackets and thereby changes its position relative to it, it moves a short distance to the tip 14 of the spacer screw 13 and is then carried along. In this position it is swiveled up and remains in the upper swivel position, not shown. When lowering in the opposite direction, the cover 3 swings in a horizontal position shortly before being placed in the opening 1, at which moment the spring 17 comes to rest in the recess 18 and now on the cover seated in the seal presses. If the cover 3 is now raised again, it remains briefly under the spring travel of the spring 17 during vertical lifting, before it is then pivoted away as described above.
- a winch not shown
