Abstract

The invention relates to a blast-proof chamber ( 1, 20, 30, 60, 70 ) for improved handling and transport of a detonation-dangerous object, wherein the said blast-proof chamber ( 1, 20, 30, 60, 70 ) comprises an outer chamber ( 2, 21, 32, 61, 71 ) comprising an inner storage chamber ( 3, 22, 33, 62, 72 ) for storage of the detonation-dangerous object. A characteristic feature of the invention is that the inner storage chamber ( 3, 22, 33, 62, 72 ) is arranged movably in the outer chamber ( 2, 21, 32, 61, 71 ) between an open and a closed position.

Claims (15)

1. Blast-proof chamber for handling and transport of a detonation-dangerous object, comprising an outer chamber in which an inner storage chamber is arranged for storage of the detonation-dangerous object, wherein the inner storage chamber is arranged movably in the outer chamber between an open and a closed position, wherein the blast-proof chamber comprises two separate closing end faces disposed in the outer chamber for closing and sealing of the inner chamber, and wherein the inner storage chamber is arranged rotatably in the outer chamber between an open and a closed position, via a rotation mechanism disposed in the outer chamber.

2. Blast-proof chamber or handling and transport of a detonation-dangerous object according to claim 1 , wherein the inner storage chamberis arranged detachably in the outer chamber.

3. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 2 , wherein the outer chamber is box-shaped or container-shaped with square or rectangular cross section comprising two long sides, a base, a roof and two end faces, whereof the two long sides are open for loading and unloading of the detonation-dangerous object to and from the inner chamber, and in that the inner chamber is tubular with circular cross section comprising a casing part and two end face parts, wherein the two end face parts are open for loading and unloading of the detonation-dangerous object.

4. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 3 , which comprise a rotation mechanism, wherein the rotation mechanism is manual and is operated with a detachable handle disposed on the top side of the outer chamber, wherein the handle is rotatable by a quarter turn, clockwise or anti-clockwise, in a horizontal plane between an open and a locked position, in which the open position automatically releases the inner chamber from the outer chamber via a pretensioned locking mechanism.

5. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 4 , which comprises a spring bolt, wherein the spring bolt is pretensioned via an electromagnetically controlled spring mechanism.

6. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 3 , which comprise a release mechanism, wherein the release mechanism comprises a spring bolt and a pretensioning mechanism, wherein the spring bolt in the pretensioned state locks the inner chamber and in the non-pretensioned state releases the inner chamber.

7. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 3 , wherein the outer chamber also comprises a rotatable support plate on which the inner chamber rests.

8. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 1 , wherein the outer chamber is box-shaped or container-shaped with square or rectangular cross section comprising two long sides , a base, a roof and two end faces, whereof the two long sides are open for loading and unloading of the detonation-dangerous object to and from the inner chamber, and in that the inner chamber is tubular with circular cross section comprising a casing part and two end face parts, wherein the two end face parts are open for loading and unloading of the detonation-dangerous object.

9. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 8 , wherein the outer chamber also comprises a rotatable support plate on which the inner chamber rests.

10. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 1 , wherein the inner storage chamber is rotatable in a vertical plane of the outer chamber.

11. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 1 , wherein the closing end faces are arranged movably in the axial direction in the outer chamber via hydraulic pistons disposed on the inner side of the outer chamber.

12. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 1 , wherein the two closing end faces comprise an expandable sealing strip for locking and sealing of the inner chamber.

13. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 1 , wherein the blast-proof chamber comprises a rotation mechanism, wherein the rotation mechanism is manual and is operated with a detachable handle disposed on the top side of the outer chamber, wherein the handle is rotatable by a quarter turn, clockwise or anticlockwise, in the horizontal plane between an open and a locked position, in which the open position automatically releases the inner chamber from the outer chamber via a pretensioned locking mechanism.

14. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 13 , wherein the spring bolt is pretensioned via an electromagnetically controlled spring mechanism.

15. Blast-proof chamber for handling and transport of a detonation-dangerous object according to claim 1 , wherein the blast-proof chamber comprises a release mechanism, wherein the release mechanism comprises a spring bolt and a pretensioning mechanism, wherein the spring bolt in the pretensioned state locks the inner chamber and in the non-pretensioned state releases the inner chamber.
