Abstract
Apparatus for the spring- mounting of pipes, boilers or similar hot-conveying components in which the connection between the housing sleeve (2) and the top plate (3) and/or base plate (5) respectively of the housing is made releasable by means of a retaining ring (8) being positioned between a corrugation (9) formed at the respective end of the housing sleeve and a reduced profile portion (7) of the respective plate. By this arrangement it is possible to prevent corrosion protection previously carried out from being damaged and to allow inspection without obstruction. The final assembly may thus be carried out in such a way as to render deformation, heating by welding or other processes, which adversely affect the corrosion protection, no longer necessary. <IMAGE>
Description
SPECIFICATION
Apparatus for the spring-mounting of components
This invention relates to apparatus for the springmounting of components, particularly pipes, boilers or similar hot-conveying components, having a housing, in particular a circular cylindrical housing, comprising a housing sleeve, a top plate closing the latter at one end and a base plate closing the housing sleeve at the other end, the plates being joined to the housing sleeve, one of the plates having at least one opening, a spring element disposed in the housing additionally being supported at one end against the base plate and the load on the spring element being distributed at the other end thereof by way of a spring plate and at least one support means such as a support rod which is connected thereto or associated therewith, which is preferably concentric with the housing sleeve, which emerges from the housing through the opening and which is connectable to a load.
Apparatus of this type is usually circular cylindrical since the spring element consists of a helically wound spring which surrounds the support rod concentrically. Designs are quite possible, however, in which the housing has an essentially rectangular cross-section for example and the spring element consists of helical springs disposed for example next to the support rod on both sides. Reference is made below essentially to a circular cylindrical design, although the present invention is not limited to such a design.
In addition, the present invention relates both to spring shackles and to spring supports which support a hot-conveying component from beneath by way of a corresponding rest. The choice between these designs is made essentially according to local conditions.
Since the apparatus should comprise structural elements with a long service life and, on the other hand, is usually subjected to corrosive environmental conditions and particular demands are frequently made in terms of the length of service life and operational reliability, a particular problem associated with the apparatus is to protect it from corrosion. This corrosion protection can only be achieved to a limited extent in the case of known apparatus since, at least during the final assembly, there is the danger that corrosion protection measures taken will be adversely affected.
In the case of a known design the top plate and the base plate are welded to the housing sleeve. In this connection, although the top plate may be welded to the housing sleeve and the corrosion protection measures may then be taken, the remaining parts of the apparatus must then be inserted in the housing space before the base plate is put in position and welded to the housing sleeve. This last welding step may considerably impair the corrosion protection measures on account of the heating thus produced, without it subsequently being possible to inspect and where appropriate correct this properly since, in particular, access to the interior of the housing is obstructed.
In accordance with another design the top plate and the base plate are flanged over the housing sleeve at their ends Here too the same problems arise on account of the fact that the material of the housing sleeve is once more deformed during the final assembly and in this way corrosion protection measures taken may be adversely affected.
There is also a design in which a housing already provided with a top plate is closed by a base plate after insertion of the inner parts by virtue of the fact that the base plate is connected by screws to a collar on the housing sleeve. Here again the problems described arise on account of the fact that the screw fastening can destroy the corrosion protection measures taken, so that fretting corrosion is subsequently produced on the screw connections.
In all the known cases it cannot therefore be ensured that corrosion protection measures taken will remain unaffected if the apparatus is ready assembled.
The present invention thus aims to improve an apparatus of the type described above in such a way that its final assembly is possible in a form in which corrosion protection measures previously taken on the individual components can no longer be adversely affected. Furthermore, the steps required for the final assembly with respect to the preparation of the individual components involved therein present no particular requirements with respect to the observation of tolerances. Finally, the measures taken for the final assembly should ensure a maximum of operational reliability and durability, without special expenditure being generally required compared with known final assembly steps.
The present invention provides apparatus for the spring-mounting of components, comprising a housing formed by a housing sleeve, a top plate closing the housing sleeve at one end and a base plate closing the housing sleeve at the other end, the plates being joined to the housing sleeve, one of the plates having at least one opening, a spring element disposed in the housing additionally being supported at one end against the base plate and the load on the spring element being distributed at the other end thereof by way of a spring plate and at least one support means which is connected thereto or associated therewith, which emerges from the housing through the opening and which is connectable to a load, wherein the end of the housing associated with the top plate and/or the base plate has a corrugation curving around the top plate and/or the base plate and increasing the internal cross-section of the housing sleeve relative to the top plate and/orthe base plate, the external profile of the top plate and/or the base plate being less than the minimum internal profile in the region of the corrugated end of the housing, and wherein a retaining ring is inserted into the corrugation of the housing, the retaining ring being located radially within the external profile of the top plate and/or the base plate and being held in the corrugation directly or indirectly by the associated plate.
By means of the present invention it is possible to perform the final assembly of the apparatus in a way that deformation, heating or straining of the material is no longer necessary, in such a way as not to impair corrosion protection measures which are taken. In the simplest case, for example in the case of a spring shackle, the top plate may be welded to the housing sleeve and the housing formed in this way may be correspondingly protected against corrosion while permitting inspection from all sides of the corrosion protection measures. The spring element may then be inserted together with the spring shackle and the support rod, and finally the base plate may be pushed in while compressing the spring element, whereupon the retaining ring is then inserted.Under the spring force bearing upon the base plate in this case, there is then a positive locking connection between the base plate by way of the retaining ring to the corrugation of the housing of the apparatus, without a deformation operation or heating being necessary. This closure connection additionally has the advantage that it is only slightly affected by manufacturing tolerances, so that in this respect the manufacture of the apparatus according to the invention may be simplified and made less expensive.
Furthermore, the use of a corrugation ensures that the material cross-section of the housing sleeve need not be reduced for the fastening steps, and, since the retaining ring is held in the corrugation directly or indirectly by the associated plate, a maximum degree of safety is achieved as the retaining ring cannot be released from its positive locking connection with the housing sleeve.
In any case all parts of the apparatus may be finished in a form which permits unobstructed inspection of the quality of the manufacture. This applies particularly to the corrosion protection of all the parts. The assembly of the apparatus has, in addition, been made simpler and easierthan the previously known designs without foregoing the possibility of dismantling the apparatus without damage later on in order to check that the corrosion protection measures taken have been maintained.
As mentioned previously, both the top plate and the base plate may be connected to the housing in the manner according to the invention. Usually, however, one of the two parts is welded to the housing sleeve in order to provide the part formed therefrom with the corresponding corrosion protection measures and finally to perform the final assembly in the manner described.
It has been found to be advantageous for the corrugation to be made concave, for the plate associated therewith to have a reduced profile on its side remote from the spring element, for the transition occurring in the axial direction of the housing from the external profile of the plate to the reduced profile to be essentially circular or conical, for the retaining ring to have a circular cross-section and for the cross-section of the retaining ring to correspond approximately to half the depth of the corrugation.
Although it is possible, however, for the retaining ring to have an oval or even essentially rectangular cross-section for example, the use of a retaining ring having a circular cross-section permits a particularly good transmission of force without stress peaks and allows the retaining ring to be produced from commercially available circular material. On the other hand, the reduced profile of the plate which covers the retaining ring radially internally is used in a simple manner to prevent the retaining ring from moving radially inwardly out of the corrugation relative to the housing.
It has been found to be advantageous for the top plate and/or the base plate to be made externally cylindrical in their reduced profile and for the radial difference between the external profile and the reduced profile to correspond approximately to half the cross-section of the retaining ring. A design is then produced in which the reduced external profile of the top plate and/or the base plate supports the retaining ring radially internally in such a way that it remains in the corrugation of the housing sleeve. In the cases described above, the support by the retaining ring is effected on the one hand by way of the arcuate shape of the corrugation of the housing sleeve and on the other hand by the circular or conical shape between the external profile and the reduced profile of the top plate or the base plate.
This support avoids angular loading and linear shearing loading of the components affected. This, together with the radial support of the retaining ring by the reduced profile of the top plate or the base plate, has the result that breaks and sudden failures of the axial mounting of the top plate and/or the base plate cannot occur in the housing sleeve.
The structure described is particularly suitable for a plate against which the spring element is supported.
If an apparatus is considered in which the load is applied from above and in which the top plate facing the load is accordingly not acted upon by the spring element, it is advantageous for the reduced profile to be increased again to the external profile while forming a peripheral groove having a width and depth greater than the cross-section of the retaining ring, and for locking means to be provided distributed over the periphery in the region of the peripheral groove such that when the locking means are inserted the retaining ring is pressed into the corrugation. In this connection, therefore, the locking means form blocking elements which may be inserted or pushed in. However, the same design may also of course be used simultaneously or alternatively for the part acted upon by the force of the spring means.
The locking means may be pins firmly inserted in axially parallel bores. It is also possible, however, for the locking means to be for example a tapered ring which may be inserted after the retaining ring and which may be brought to bear against a corresponding tapered surface of the top plate and/or the base plate.
Another possible structure may consist in the reduced profile of the top plate and/or the base plate being increased again to the external profile while forming a peripheral groove having a width greater than the cross-section of the retaining ring and a depth corresponding approximately to half the cross-section of the retaining ring, and in the extension being formed by an annular plate placed upon the top plate and/or the base plate. In this connection the top plate and/or the base plate is first pressed into the opening of the housing, and then the retaining ring is inserted and finally the annular plate is placed thereon with the aid of screws for example, so that in this way a peripheral groove, which holds the retaining ring in the corrugation of the housing sleeve, is formed on the top plate or on the base plate.
It is possible for the retaining ring to comprise a plurality of bent parts. The retaining ring may consist of corrosion-resistant material, for example a strong synthetic material or rust-proof steel. It may, however, also be produced from hot-galvanised material for example.
The invention will be further described, by way of example only, with reference to the accompanying drawings, in which Figure lisa side view of a spring shackle partially in section;
Figure 2 is a partial view from below of the spring shackle according to Figure 1;
Figure 3 shows the closure connection of the base plate of the spring shackle according to Figure 1 on an enlarged scale;
Figure 4 is a closure connection according to
Figure 3 having a differently designed base plate;
Figure 5 is a further closure connection according to Figure 3 having a differently designed base plate;
Figure 6 is a closure connection of a top plate of a support for hot-conveying parts during and after assembly;
Figure 7 is a modification of the design according to Figure 6; and
Figure 8 is a further modification of the design according to Figure 6.
Figures 1 to 3 show a spring shackle 1 comprising a housing sleeve 2 with a top plate 3 welded thereon, the unit formed in this way being suspendable in situ and in position by way of suspension bars 4.
The bottom of the spring shackle is closed by a base plate 5, the external peripheral profile 6 of which can pass through the internal cross-section of the housing sleeve 2 and has a reduced diameter portion 7. The transition between the peripheral profile 6 and the reduced diameter portion 7 is circular, so as to permit abutment on a retaining ring 8 which is supported in a corrugation 9 in the associated end of the housing sleeve 2.
A helically wound spring 10 is supported against the base plate 5, and the load in the form of for example a pipe is suspended in turn on the spring 10 by way of a spring plate 11 and a supporting rod 12 secured thereto.
The housing 2,3,4 may first be produced and protected from corrosion by appropriate steps, it being possible freely to check that the rustprotection measures are satisfactory. The base plate 5 and the retaining ring 8 may likewise be produced individually and provided with rust-protection means.
Assembly is carried out by the spring plate 11 with the supporting rod 12 and then the spring 10 being inserted into the housing 2,3,4. Subsequently the base plate 5 is inserted while compressing the spring 10 in such a way that the retaining ring 8 may be inserted into the corrugation 9, The base plate 5 is thereupon released and bears with its increased periphery 6 against the retaining ring 8, whereby the final assembly is completed. Then, with its reduced portion 7 the base plate 5 holds the retaining ring 8 in the corrugation 9 in such a way that the retaining ring 8 can no longer yield radially inwards, so a to provide a retention action even if the retaining ring breaks for example during operation.In addition, the retaining connection 6,7,8,9 is free of edge loading, and in particular the final assembly is possible without parts of the spring shackle having, for example, to be disformed and heated in the course of welding.
The dimensions of the depth of the corrugation 9 on the one hand and the reduced portion 7 on the other are selected such that they correspond approximately to half of the cross-section of the retaining ring 8.
Figure 2 shows the spring shackle according to
Figure 1 partially from below and Figure 3 illustrates an enlarged detail of the locking connection between the housing sleeve 2 and the base plate 5.
Figure 4 shows, with the same design of the housing 2, corrugation 9 and inserted retaining ring 8, a modified base plate 13 which, in contrast to
Figures 1 to 3, is constructed not as a revolving member but as a bent moulded component. In this case the external profile is formed by a collar 14 which passes into a reduced diameter portion 15 in an arcuate manner. In order to support the spring 10 the base plate 13 forms a base which forms a through opening 16 for the supporting rod 12 by means of a flanged-over portion 17.
Figure 5 again shows the housing 2 with the corrugation 9 and inserted retaining ring 8, a base plate 18 being formed by a cast component, the external diameter 19 of which is slightly less than the free internal diameter of the housing 2 and which passes into a reduced diameter portion 20 in a circular manner corresponding to the retaining ring 8.
The base plates according to Figures 4 and 5 are assembled as described with reference to Figures 1 to3.
In the embodiments described, a circular cylindrical spring shackle has been illustrated. The spring shackle may alternatively have an essentially rectangular profile for example, and this also applies to the embodiments to be described below.
In Figure 6 is shown a spring support in which a top plate has an opening for a supporting rod on which the load is supported above. Accordingly, the base plate of the housing may advantageously be welded to the housing sleeve, so that the final assembly is carried out by way of the top plate which is not, however, spring-loaded in this case.
For this purpose, according to Figure 6 the top of a housing sleeve 21 is provided with a corrugation 22 into which a retaining ring 23 may be inserted. For this purpose, a top plate 24 has a peripheral groove 25, the depth of which corresponds at least to the cross-section of the retaining ring 23. The peripheral groove is traversed by bores 26 distributed over the periphery of the top plate 24 in such a way that pins 27 inserted into the bores 26 press the retaining ring radially outwards into the corrugation 22. In order that the top plate 24 is locked on the retaining ring 23 in both axial directions, the radial external profile 28 is increased again on the other side of the retaining ring 23, so that the retaining ring 23 is gripped on both sides by the top plate 24 and, as clearly shown in Figure 6, preferably bears against the end of the housing sleeve 21.
Figure 7 shows a variation of the design according to Figure 6, which is produced by an annular plate 30 being mounted on a top plate 29 by way of screws 31. In this connection, it is not necessary to arrange a reduced diameter portion 32 of the top plate in such a way that a retaining ring 33 fits wholly therein. It is only necessary, rather, to dimension this reduced portion 32 to be approximately half the diameter of the retaining ring 33.
Afurthervariantis illustrated in Figure 8, in which a top plate 34 is provided with a peripheral recess 35 such that a retaining ring 36 has space therein for assembly without engaging the internal profile of a housing sleeve 37 and its corrugation 38. After inserting the top plate 34 the closure is effected by a wedge-shaped ring 39 which rests with its inner surface against a corresponding wedge surface 40 of the top plate 34 and bears on the other hand against the terminal edge of the housing corrugation 38 and at the same time forms the abutment of the top plate 34 against the retaining ring 36.
Figures 6 to 8 show top plate closures for a load-bearing spring support, in which it is envisaged that at the opposite end the housing sleeve is closed by a base plate which is welded for example to the housing sleeve and against which the spring bearing the load is supported. However, it is possible to provide the housing sleeve at both ends with base and top plates locked relative to the housing in the manner illustrated. In the case, for example, of the design according to Figure 6, the top plate 3 according to Figure 1 could be attached in this way, and at the same time the base plate 5 could be attached in the manner illustrated in Figure 1, but could also be welded to the housing sleeve 2.
In the same way, in the case of a spring support, such as illustrated in Figures 6 to 8, the base plate may be secured in the manner described with reference to Figures 1 to 5.
All the embodiments described permit the reliable verification of corrosion protection measures before the final assembly, without deformation procedures, heating by welding or the like being necessary for the final assembly. This applies both to circular cylindrical and to essentially rectangular spring supports since the retaining rings may also of course have an essentially rectangular shape as they are held by virtue of the assembly described in their position between the corrugation and the top plate or base plate in such a way that they cannot deviate from their supported position.
