Definitions

  • the invention relates to a container with a container opening and with a lid supported on a shoulder of the container opening, the inside of the container opening having an incision into which a plurality of latches for fixing the lid can be inserted.
  • Such a container is known from DE-OS 27 38 592.
  • a shielding and a holding lid are assigned to the container.
  • the holding cover has a plurality of parts which are movable against one another under frictional engagement and which serve to fix the cover. With these parts sliding among each other, corrosion or contamination, which can ultimately lead to malfunctions, cannot be excluded. The wedging of the bolts leads to a rigid connection, which can be disadvantageous in various load cases.
  • the cover is formed in one piece and is provided on its circumferential surface with such an annular groove that the cover can yield resiliently in the region of the annular groove under load.
  • the connection is flexible within the scope of the spring travel given by the ring groove and can compensate for critical load cases.
  • One embodiment of the lid fixing of the container provides that a tool for introducing or removing the lid bracing is supported in the incision assigned to the container opening, that the supporting elements for the tool are connected to a holding plate, which in turn is on the side surface of the lid facing away from the shoulder attacking clamping cylinder carries.
  • the support elements serve as a fixed point for the clamping cylinders, which cause the cover to be compressed in the area of the annular groove. During the compressed state, the relieved bolts are pushed in and out. If the clamping force of the clamping cylinder is released, a non-positive connection is made between the lid and the container opening when the bolts are engaged. It is not necessary to keep the tool in the area of the container opening.
  • a cylinder fastened to the holding plate or to the plate of the tool carries a supporting element and moves the same relative to one or both cuts.
  • lid fixing of the container provides that a clamping element of a tool for initiating or removing the lid bracing engages over the container opening, that a plurality of supports protrude from a side of the clamping element facing the container, which supports contact the lid surface between the bolts and that supporting elements of the tool on the one hand engage in the incision and on the other hand are connected to the clamping element.
  • the use of a single tensioning element ensures that the cover is pressurized evenly.
  • the inside of the container opening has a further cut arranged above the first cut, the support elements of the tool optionally engaging in the first and / or in the further cut.
  • a cylinder fastened to the holding plate or to the plate of the tool carries a supporting element and moves the same relative to one or both cuts.
  • a further embodiment is characterized in that the tensioning element consists of two parallel plates and a bellows connecting them to one another, that a plurality of tie rods connected to a support element penetrate the plates and the space which can be acted upon by a pressure medium, and that each tie rod is connected to their End facing away from the support element is provided with a yoke resting on the top of the upper plate.
  • a rigid connection between the upper plate of the tensioning element and the container opening is achieved by the support element and the yoke, so that when the tensioning element is pressurized, the lid yields in the region of its annular groove.
  • Each pull rod is preferably surrounded by a protective cover which bridges the space between the plates and is sealingly connected to the plates.
  • the tensioning element consists of two parallel plates and a bellows connecting them to one another, that the periphery of the plates projects beyond the bellows, one with each support element connected pull rod passes through the area of the plates which projects beyond the bellows and that each pull rod is provided at its end facing away from the supporting element with a yoke resting on the upper side of the upper plate.
  • a preferred embodiment is characterized in that a cylinder responsible for the retraction and extension of a bolt is carried by the tool and can be coupled to the side of a bolt facing away from the inside of the container opening. This ensures that the tool can be removed from the container opening when the latch is in either the open or closed position.
  • connection between the yoke and the pull rod is made via an axle bolt and that the pull rod can be rotated relative to the axle bolt.
  • the container according to the invention is described on the basis of exemplary embodiments and FIGS. 1 to 5.
  • FIG. 1 shows a sectional view of a partial area of a container 1, which is used, for example, as a pressure or vacuum container.
  • the container opening 2 has a shoulder 3 for supporting a lid 4.
  • An annular groove 5 is made in the cover from the circumference of the cover 4, which has a circular cross section.
  • the annular groove provides a resilient yielding of the cover in the region of the annular groove when a force acting on the side surfaces of the cover is applied.
  • a large number of bolts 7 (FIG. 2) are inserted in the direction of the arrow 8 and, together with the resilient design of the cover 4, cause the cover to be fixed simply and reliably relative to the container opening.
  • the thickness 9 of the untensioned cover 4 is greater than the dimension 10 between the shoulder 3 and the lower side surface of the incision b.
  • the cover can be moved as far as possible in the area of the annular groove 5 by the action of force press together so that its thickness 9 is equal to or less than dimension 10.
  • the bolts 7 can be easily pushed in when the lid is tensioned - or if the lid is to be removed - removed.
  • the spring force of the cover 4 can be determined for the respective area of application by the depth, position and shape of the annular groove.
  • the annular groove 5 has a wedge-shaped cross section, the flanks of which are convex.
  • a tool 12 for introducing or removing the cover bracing is shown.
  • a further incision 11 is made on the inside of the container opening 2 above the incision 6 for the bolt 7.
  • a plurality of supporting elements 13 of the tool 12 distributed over the circumference can be inserted into this incision 11 and form an abutment during the clamping process for the cover 4.
  • the clamping element 14 of the tool 12 is formed from two parallel plates 15, 16, which are formed by a bellows 17th are interconnected. The cavity thus formed can be acted upon by pressure medium.
  • Each support element 13 is connected to a pull rod 18. It passes through the clamping element 14 and is provided at its free end with a yoke 19 which bears against the surface of the plate 16.
  • the pull rod 18 is surrounded by a protective cover 20 which is sealingly attached to the inside of the plates in order to prevent the pressure medium from flowing out through the bushings 21 in the plates 15, 16.
  • the bushings 21 are designed as an elongated hole so as not to impede the movements of the pull rod 18 together with the support elements 13 in the direction of the arrow 22.
  • the connection between the yoke 19 and the pull rod 18 is designed as an axle bolt 32. It is firm with the yoke connected and therefore allows a rotational movement of the tie rod relative to the axle bolt.
  • the movement in the direction of arrow 22 takes place through a pressure-actuated cylinder 23, which has its fixed point on a bracket 24 of the plate 15 and is articulated with its piston on the support element 13.
  • Sixteen supports 25 protrude from the underside of the plate 15 and are designed in length in such a way that their free ends then contact the surface of the cover when the support elements 13 are inserted into the further incision 11.
  • the supports 25 touch the lid surface between two bars 7, since the spring force of the lid can be overcome with the least effort at these points of attack lying on the lid periphery.
  • the upper plate 16 of the clamping element 14 is held in position by the rigid connection of the pull rods 18 distributed in several copies on the circumference to the container opening 2, while the plate 15 with the supports 25 so is moved far down, as the travel of the cover 4 allows.
  • the bolts 7 are retracted or withdrawn from the cut b with the aid of a pressure-actuated cylinder 26 during the pressurization of the cover. If the tensioning element 14 is relaxed when the bolts are retracted, the bolts are jammed by the spring force of the cover, so that a reliable closure of the container is ensured.
  • the cover seal 27 lies against an incline of the container, so that the cover sits directly on the shoulder 3 of the container opening 2.
  • the cylinder 26 assigned to each bolt is fastened to the same bracket 24 as the cylinder 23.
  • the side of a bolt 7 facing away from the inside of the container opening is also connected the piston rod of the cylinder 2b is coupled. This ensures that the tool can be removed after the clamping process has been carried out.
  • FIG. 4 Another design of the tool 12 can be seen from FIG. 4.
  • the cover 4 is clamped with sixteen clamping cylinders 29, the pistons 30 of which carry out between the support elements 13a or the bolts 7a and which contact the side surface of the cover 4 opposite the shoulder 3.
  • the clamping cylinders 29 are carried by a holding plate 31, which in turn can be fixed relative to the container opening 2 by means of support elements 13a which can be inserted and executed in the incision 11.
  • the compression of the cover in the area of the annular groove 5a thus takes place with the tensioning cylinders 29 in relation to the holding plate 31 serving as an abutment.
  • 28 movable.
  • the cylinders 23, 26 are attached to brackets 24a of the holding plate 31.
  • the further incision 11 can be omitted.
  • the support elements 13, 13a of the tool 12 then engage in the incision b between the bars 7, 7a. It must be ensured that there is still sufficient space for the supports 25 and the pistons 30. If the container 1 has both cuts 6, 11, there is also the possibility of engaging a number of support elements 13, 13a with one cut 6 and a further number with the other cut 11.
  • FIG. 5 Another embodiment of the tensioning element 14 according to FIG. 3 is shown in FIG. 5.
  • the tie rods 18 there penetrate the peripheral area of the plates 15, 16 located outside the bellows 17. Sealing of the tie rods 18 against the interior of the tensioning element 14 is therefore not necessary.
