Definitions
- the present invention relates to a device for setting in place of temporary supports in conduits circulation of fluid such as those encountered in incineration plants as well as a circulation of fluid equipped with such a device.
- Incineration facilities such as ovens household waste, are equipped with energy recovery which can still be called heat exchanger. Indeed, these boilers have for vocation to exhaust the calories contained in circuits hot fluids, such as fumes, systems incineration.
- the circulation conduits of fumes from these boilers are provided in their wall with water circulation tubes which heat up by conduction contact of the walls heated by the fumes reaching temperatures close to 1000 ° C.
- the problem of conduits circulation of such hot fluids charged with particles reside in their rapid fouling which requires a frequent cleaning of the interior walls of the conduits. To carry out this cleaning, it is necessary to have security installations, such as scaffolding, floors or the like, especially for working in elevation.
- conduits are large conduits dimension with sometimes inclined walls, the mounting of such security installations turn out to be tedious.
- This mounting is made complex by the fact that we have found that when we permanently had in the duct anchors or supports for these security installations, we involved in time, due to the nature of the fluids, erosion or corrosion or more generally a degradation of support parts or anchors so that these supports or anchors were rendered quickly unusable.
- the result today is a veritable problem for the installation of these security installations.
- supports or anchors arranged at remains inside the duct are likely to disrupt the flow of fluids inside the leads.
- Japanese patent application JP-A-02 027 061 describes a device for the establishment of a temporary support in a circulation duct of fluid consisting of a tubular structure intended for fit into holes through the wall, these through holes being arranged opposite.
- This continuous tubular structure of length greater than inside diameter of the duct to be fitted is introduced by one of the holes passing through the wall in said conduit to extend into the other opening by forming a bridge connection between said orifices.
- This structure thus forms a suspension bridge between the parts of walls provided orifices crossing the pipe.
- This suspension bridge serves on receipt of a basket or beams extending perpendicular to said tubular structure.
- the design of such a tubular structure poses a certain number of drawbacks.
- this tubular structure directly constitutes a supporting structure, which requires on the one hand to practice in the wall of the driving to equip large orifices, on the other hand to increase the weight of said structure. Of this fact again results in a difficult mounting of all.
- An object of the present invention is therefore to propose a device for the installation of temporary support in fluid circulation ducts, the design of this device allowing not to have, apart from maintenance periods, of any part likely to protrude or disturb the flow of fluids inside the duct (s) while authorizing, during maintenance, rapid assembly, easy and safe of the whole device for the receipt of a security installation such as scaffolding, floor or other.

- This assembly is more particularly represented in figure 3 in which the console 4 consists of an I-profile perforated extending in a vertical plane parallel to the axis longitudinal of the conduit 11, this profile being provided, at one of its ends, of a plate 5 perpendicular to the plane of the profile. If there are no shoulders on pin 3, the plate 5 can come to bear on the inside of the inner wall 11A of the conduit 11. In the presence of a shoulder on pin 3, this plate 5 can come in abutment against said shoulder.
- the console 4 is equipped with a tab 8 perforated threading on the end 3A of the pin 3.
- the transverse passage 6 of spindle 3 extends between tab 8 and free end 3A of the spindle for the insertion of a locking pin.
- tab 8 and plate 5 cooperate to ensure at least the axial immobilization of the console 4 on spindle 3 and possibly axial immobilization of the spindle 3 relative to the tubular structure 2.
- the spindle 3 is equipped with a shoulder 13 forming a stop to the axial movement of the tab 8 carried by the console 4. So, as illustrated by the different examples above, the plate 5 and / or the tab 8 are arranged to come, when positioning the console 4 on the spindle 3, against a shoulder 13 formed on the spindle 3.
- Pin 3 further comprises, at its outer end 3B to the conduit 11, a plate 9 secured to the spindle 3.
- This plate 9 is capable of being secured temporarily to a flange 10 carried by the end outer 2B of the sleeve 2.
- Plate 9 and flange 10 are secured to each other during the maintenance period by clamping. This results in an axial immobilization of the pin 3 inside the tubular element 2.
- the console 4 positioned inside the duct as support or anchoring of a safety structure 12, in particular of a scaffolding floor, to allow cleaning or maintenance of the duct 11 in all security.
- FIG. 4 One such example of a safety structure 12 is in particular shown in Figure 4.
- the conduit 11 is equipped with devices 1 arranged at different heights along the inner walls of the conduit.
- Each device receives a beam intended to rest on two devices arranged side by side.
- These beams serve themselves of support to a deck intended to form a scaffolding floor.
- This decking can include, in one chosen location, an access hatch allowing a operator, positioned on a first floor, to have access to a second floor arranged at a level higher than inside the duct. As illustrated in Figure 4, this access is made possible via a ladder 13 disposed between the two floors.
- Support 12 temporary constituted here by a security structure does will not be described in more detail as it may affect a large number of forms.
- the device is partially disassembled.
- the consoles 4 are removed by simple pinning and the pin 3 is completely or partially extracted from sleeve 2 after separation of parts 9 and 10.
- pin 3 is intended to be completely removed from the tubular structure 2 which is then closed at its projecting end 2B by through a obturation organ constituted by example by a simple plate intended to be applied against the flange 10 of the tubular structure 2, this platinum being again maintained by clamping.
- each end 3A of pin 3, intended to project from the interior of the duct 11 during maintenance is permanently fitted with a console 4. This design applies to pins 3 inserted in the sleeves 2 from inside the conduit 11 to equip.
- Fluid circulation conduits of the type encountered especially in incineration plants equipped with devices described above are easily recognizable because they have, permanently on their wall, at least two facing tubular elements 2 intended for constitute the receiving sleeves of at least two pins 3. These tubular elements 2 are positioned facing each other. selected locations on the wall of conduit 11 for ensure an optimized positioning of the structures of security. It therefore results, thanks to such a device, possible optimization of the positioning of structures of security.
- a device 1 of the aforementioned type is particularly easy to assemble. he suffices to introduce each pin 3 inside of the tubular structure 2 by the end 2B or the end 2A of the structure 2, to position the console 4 at the end of the spindle 3 by simply passing the spindle 3 through the holes in the plate 5 and the tab 8 of the console 4 or in the plates 5, 5A of console 4, then immobilize the assembly by fitting pin or screwing of screws. All of these operations can be done in an extremely short time while ensuring safe assembly of the assembly.
