Description

The present invention relates to a device for holding a cabling positioned in a guiding system, such as a cable duct. The invention also relates to a wiring installation, including a wiring, a guiding system and at least one device for holding the wiring positioned in the guiding system. The invention also relates to a method for implementing such a holding device. Conventionally, an industrial wiring installation comprises a wiring, a guidance system, and means for maintaining the wiring positioned in the guidance system. For example, the wiring may include electrical power and control cables, as well as compressed air transport pipes, connected to one or more industrial machines. The guidance system is designed to support and guide the cables and pipes to the machines. For this purpose, it is known to use commercially available stainless steel cable trays, for example of the "cablofils" (registered trademark) type. In the food industry, cables and pipes in production rooms are subjected to washing water and food residues processed by machinery. It is therefore important to be able to thoroughly clean and inspect these cables and hoses to avoid any source of contamination. In practice, the cables and air pipes are held in place in the cablofils by holding means. In order to meet the above requirements, the holding means must allow a certain freedom of movement of the cables and pipes, so that all their periphery remains easily accessible. Thus, the washing operators can clean the cables and pipes all around them. To date, it is known to use holding collars, for example of the "serflex" (registered trademark) type, for fixing the cables and pipes on the cablofils. Generally, a collar is positioned every twenty centimeters along the cablofils. The installation of these necklaces is very tedious. If the cable is changed, all the collars are cut, then new collars are put in place to hold the new cable on the cablofils. In addition, the collars do not allow to leave the cable free and easily accessible for washing. The necklace loop is a hard-to-clean area where food can come and stay. The object of the present invention is to provide an improved wiring retention device.

For this purpose, the subject of the invention is a device for holding a wiring positioned in a guiding system, the wiring comprising at least one cable or pipe which extends along the guiding system, the holding device being adapted to be attached to the guide system and support at least one cable or pipe belonging to the wiring. The holding device is characterized in that it comprises a body which extends between two ends; fastening means of the holding device on the guide system; and at least one support arm extending transversely of the body and adapted to support at least one cable or pipe. Thus, the invention makes it possible to hold the cables and / or pipes in position along the guide system in a simple and practical manner. The device according to the invention is adapted to be fixed on any fixed point of the guidance system. The device according to the invention is not destroyed during disassembly, unlike a holding collar, which is more economically advantageous. In addition, this device allows easy access to cables and pipes for cleaning.

According to other advantageous features of the invention, taken separately or in combination: - The fixing means are positioned at both ends of the body of the holding device. - The fastening means are positioned at the ends of the support arms of the holding device. - The fastening means comprise a fastening hook to the guide system. - The fixing means comprise two lugs forming a fork attachment to the guide system. - The or each support arm has an upper surface for receiving the cable or pipes, in particular without other contact area between the wiring and the holding device. - The body, the fastening means and the support arms form a rigid structure.

The invention also relates to a wiring installation including: a wiring comprising at least one cable or pipe, a guiding system receiving the wiring, and at least one device for holding the wiring positioned in the guiding system. The wiring installation is characterized in that the one or more holding devices are as mentioned above.

The invention also relates to a method of implementing such a holding device. The method comprises a mounting phase of the holding device consisting, on the one hand, to position the fixing means of the holding device on the guide system and, on the other hand, to position at least one cable or pipe belonging to the cabling on the support arm or arms of the holding device, in particular without using a particular tool and without exerting tension forces on part of the holding device. According to an advantageous characteristic, the method comprises a cleaning phase of the wiring installation formed by the wiring, the guiding system and the holding device, including a step of cleaning the cable or pipes supported by the arm or arms supporting the holding device, by lifting this or these cables or pipes to separate them from an upper surface of the or each support arm.

The fixing means 50 is formed at the upper end 41, while the fixing means 60 is formed at the lower end 42. The fixing means 50 comprises a hook 51 bent 180 degrees in the direction of the arm 71. The hook 51 defines a space 52 for receiving the upper post 21 of the system 20. The fixing means 60 comprises two spaced tabs 61 which extend opposite the body 40 fork-shaped. The two tabs 61 define a space 62 for receiving the lower upright 24 of the system 20. As shown in FIG. 1, several holding devices 30 are distributed along the wiring 10 and the system 20. The number of devices 30 depends on the length of the installation 1. The method of implementation of the holding device 30 is detailed below. The method comprises a mounting phase of the device 30 consisting, on the one hand, to position the fastening means 50 and 60 on the system 20 and, on the other hand, to position at least one cable or pipe 11-12 on the support arm 71 and 72, especially without using any particular tool and without exerting tension forces on a portion of the holding device 30. As shown in Figure 3, the fixing means 60 is first positioned on 20. The upright 24 is nested in the space 62, between the tabs 61. At this stage, the device 30 can pivot around the upright 24. As shown in FIG. 4, the body 40 is then brought into abutment against the amount 21. The hook 51 is then positioned above the post 21. As shown in FIG. 5, the fastening means 50 is in turn positioned on the system 20. The post 21 is fitted into the space 52 of the hook 51. The ends 91 and 92 of the arms 71 and 81 are then positioned at the 23 and 23. Thanks to the hook 51 and the tabs 61, the device 30 easily fits and disconnects the uprights 21 and 24 of the system 20. The implementation of the wiring 10 and the device 30 in the system 20 is faster and more convenient than with holding collars. When the device 30 is disposed on the system 20, the body 40 extends generally in the vertical direction parallel to the axis Z1, while the arms 71 and 72 extend generally in the transverse direction parallel to the axis X1 as shown in FIG. 2. The cables 11 are supported by the surface 81 of the arm 71, the cables 12 are supported by the surface 82 of the arm 72, and the cables 13 are supported by the uprights 28 of the system 20. As an alternative all the cables 11-13 can be supported by the arms 71 and 72. The comb shape of the device 30 makes it possible to produce cable stages 11-13 in the system 20, in particular in order to separate different types of cables (air, command, power, network ...).

The method also comprises a cleaning phase of the installation 1, including in particular a cleaning step of the cables 11-12 supported by the support arms 71 and 72, a step of cleaning the cables 13 supported by the uprights 28, a cleaning step of the uprights 21-28 of the system 20 and a cleaning step of the device or devices 30. These different steps are generally simultaneous, depending on the progress of the cleaning along the installation 1, along the longitudinal direction defined by the X1 axis. When cleaning the cables 11-12, they are spaced from the upper surface 81 or 82 of each support arm 71 or 72, so as to clean the cables 11-12 all around them. These surfaces 81 and 82 constitute the only contact zones of the device 30 with the wiring 10. In comparison with the holding collars, the cleaning of the wiring 10 is facilitated and its efficiency is improved. The method may also include a disassembly phase of the device 30 consisting, on the one hand, to remove the fastening means 50 and 60 with respect to the system 20 and, on the other hand, to remove the cables 11-12 supported by the support arm 71 and 72 and / or position additional cables on the support arms 71 and 72, in particular without using a particular tool and without exerting tension forces on a portion of the holding device 30. The hook 51 and the tabs 61 can be easily disengaged from the uprights 21 and 24, so that the device 30 is easily removable, partially or completely. In particular, the device 30 makes it possible to replace a cable 11-13 in a simple and fast manner in comparison with the holding collars.
