Definitions
- the invention relates to optical micro-cable drivers for wiring, especially inside the buildings.
- These micro-cable drivers find their application in cable laying by blowing, pushing, pulling. Their use is also possible in porting, switching, pushing alone, etc.
- a first type of laying device is based on the principle of carrying ( Figure 1). These devices exert for this advance of the cable by air flow.
- the apparatus for blow-pulling (FIG. 2) exerts an advance of cable by air pressure at the head of the cable on a piston and by pushing by rotation of rollers.
- a type of laying apparatus has already been proposed, as shown in FIG. 1, making it possible to set up optical wiring of various types, in particular underground, in building adduction, but with difficulty in building because the spacing between the air injection system and the drive rollers make the device bulky.
- the cable to be laid is specific in terms of diameter and rigidity.
- the underground cable for example, has a larger diameter than a building cable.
- the installation of optical cables in the buildings may also require some interventions in the cable trays of the building, in particular require a cascade of such series laying devices on the cable (Figure 3).
- the cascade consists in setting up a second line laying device to increase the laying performance in the case where the system is limited.
- the apparatus described in patent FR 2 774 777 integrates the air injection system upstream of the drive rollers which are thus placed in a sealed volume. During a cascade, you must open the device mentioned above to allow the installation of the cable. When the device is closed, it is typically faced with sealing problems: a seal, however necessary with this device, does not reposition well in its housing, which creates air leaks.
- This type of known device which is not dimensioned for the building in particular, can not, moreover, not always be installed in the cable trays.
- this type of device does not bring simplicity of handling to the installer. Indeed, because of its size and weight, this type of device is not manageable.
- the object of the invention is to provide an optical cable laying apparatus, by blowing, pulling or pushing, which allows a simplification of the manipulations, in particular the introduction of the cable between the rollers and end of the tube without intervention on the sealing, a cascading of the device, and which is suitable for laying cables in buildings.
- This object is achieved according to the invention with an optical cable laying apparatus comprising means for fixing a rotary motor, at least one friction drive roller on the cable, a compressed air inlet for the cable drive, characterized in that the motor fixing means, said at least one roller and the compressed air inlet are arranged in such a way that the motor axis, the compressed air supply direction and the cable driven by the roller are substantially parallel to each other.
- FIG. 1 shows a laying device by carrying according to the prior art
- FIG. 2 represents a blow-blown installation device according to the prior art
- FIG. 3 represents a cascade of two blow-blower devices according to the prior art
- - Figure 4 shows in perspective a head of a laying device according to a first embodiment of the invention
- - Figure 5 shows the same laying device, in overall view;
- - Figure 6 is a detailed view of a laying head of the same device, provided with its housing;
- FIG. 7 is a schematic view of the device according to this same variant.
- FIG. 8 and 9 are perspective views of a control member of the same device, respectively inactive and active positions.
- the device presented here is a device adapted to the building. It transmits the movement to the cable while ensuring its protection.
- the design and selection of the elements of the device have been made to obtain a device the least bulky possible.
- the laying device also has a lower weight that allows easy handling and use.
- the laying device can thus be used in cable trays having small dimensions, and / or cable tray being inaccessible.
- the screwdriver body 10 is held on a support member
- screwdriver 10 can be replaced in the context of the invention, by a body of usual drill, return side handle.
- a body of usual drill, return side handle There is also provided a variant using a screwdriver whose handle can be folded transversely to the direction of the rotary axis thereof.
- the kinematic chain is furthermore the following.
- the movement is transmitted from the screwdriver 10 to the apparatus by a screwdriver bit 12 which attaches to a torque limiter 30.
- the tip 12 of the laying device allows the transmission of movement between the power supply and the transmission system, even with a certain angle of inclination of the power supply.
- the system is provided with an interface 15 between the screwdriver 10 and the torque limiter 30, which consists of a key-type bit 16 which allows the movement to be transmitted at different stages of inclination of the feed.
- a holding member is used to prevent inappropriate movement of the elements.
- the screwdriver head is here in a hexagonal hollow form, corresponding to a key awl cavity.
- the driving head of the torque limiter 30 cooperating with the screwdriver 10 is itself in the form of a key awl, that is to say with hexagonal section.
- this head has a certain rounding at its end, that is to say a lack of strict edges at the edge of the hexagonal section, which allows a certain angular offset between the axis of the screwdriver and the axis of the complementary tree.
- a rounded head such as the head 16 allows a rotational drive despite the strict non-alignment of the two associated pivoting shafts, namely the driven shaft and the shaft of the screwdriver.
- the torque limiter 30 is here magnetic powder type, known per se.
- the rotational movement is then transmitted from the torque limiter 30 to an angle transmission module 40, the connection between the two axes being made by a coupling member 50.
- motor roller 60 On the output shaft of the bevel gear is fixed a roller called motor roller 60.
- a clamping adjustment device 80 of the rollers 60 and 70 which is provided with a control wheel 91, by screw thread, the pressure exerted on the roller 70 which is transversely movable towards the roller 60 with fixed axis located opposite.
- This device shown in particular in Figure 4, has a support pushing the axis of the roller 70 to the opposite roller 60.
- This support is in the form of a lever 92 whose center 93 produces the support force, while the ends 94 and 95 of the lever each support a corresponding support located opposite to the axis of the roller 70.
- This doubling of forces reduces the size of the system elements and therefore allow a small footprint.
- one of the ends 92 comes to cooperate with a helical spring 95 pushing the lever towards the cable.
- the other end of the lever comes to cooperate with the head of the screw whose advancement in support is set by the wheel 91 above.
- the wheel 91 generates a selected bearing force
- the coil spring 95 allows a movement of the roller 70 upward, including the introduction of the cable.
- This clamping force adjustment assembly is disposed on a separable module from the rest of the cable-laying device.
- the presence of the helical spring 95 thus allows the rollers 60 and 70 to be shifted for the positioning of the cable, without having to actuate the knob 91 and thus without having to disturb the degree of clamping in the presence.
- the assembly is held at various locations on a support plate 100.
- a centering system 110 is provided to correctly position the bevel gear, the crushing system and a pair of shims.
- connection 120 compressed air inlet in the form of a T-pipe, the vertical base joined the end 130 of compressed air supply at the perpendicular of the latter.
- This same vertical base is pivotably mounted so that the two horizontal branches of the T are pivotable, in particular to join, from the general direction of the assembly, a direction perpendicular to the device.
- the two horizontal branches of the T In its perpendicular position, the two horizontal branches of the T, forming the passage of the cable before introduction into the tube, do not open opposite rollers 60 and 70, but remain free of any bulk at each of their ends.
- the introduction of the cable is therefore much easier in this arrangement, and allows in particular the introduction of a pre-equipped cable ferule, pacifier and piston.
- the T-shaped connector 120 is pivoted to introduce the current portion of the cable between the two rollers 60 and 70 and come to place the piston at the opening of the tube to be equipped.
- This introduction procedure significantly facilitates the installation of cable laying in the presence.
- a nipple closes the connector 120 T upstream of the compressed air supply.
- a tube receiving the cable is associated with the direct downstream T-piece of the latter.
- the introduction of the cable into the device can also be achieved without pivoting the T-fitting to the perpendicular. Indeed, a simple oblique shift may be sufficient for such placement before clamping in the rollers and before introduction into the tube.
- a pivoting air access makes it easy to slide the cable into the tube. Slide a set cable + piston + ferrule + sealing nipple will be possible with this swivel connection.
- a shell 140 protects the device from shock and dust.
- Counters 150 and 160 are positioned on this shell and measure the length of cable laid and the speed of installation. A system for measuring these parameters is mounted on the device and connected to these counters.
- An angle gear 55 of the 90 ° bevel gear type makes it possible to change the laying direction of the cable.
- This angle deflector 55 allows the positioning of the device in a cable tray.
- the axis, thus also here the body, of the drive motor 10 is arranged parallel to the cable 200 and to the tube 300 to receive this cable, so that these longitudinal elements, arranged thus parallel to each other, are in a minimal footprint.
- the arrival 130 of compressed air is also disposed at the inlet of the device in a direction parallel to the axis of the rotating motor.
- This arrival is here in the form of a hollow insert for receiving a flexible pipe.
- the part of the compressed air line also fits, near the device, in the general direction of the device, thus filling a minimum footprint.
- the support plate 100 allows the mechanical strength of all of these elements.
- the hull 140 allows access to the various elements necessary for setting and laying the cable. The apparatus thus makes it possible to have direct access to the rollers 60 and
- the hull 140 surrounding all the drive members of this cable-laying is for this open in a longitudinal window 145 uncovering the active parts of each of the rollers, and in particular the intermediate portion located therebetween.
- the device is also easier to use since you can access the rollers directly (no waterproof shell).
- the device is also equipped with a cable guide which accesses the rollers directly. This accessibility makes it easy to slide the cable between rollers 60 and 70 in all installation situations.
- This asset Furthermore, it is possible to use a pre-equipped cable 200: the installation of the piston, the ferrule and the sealing nipple can be carried out at the factory or before moving on the ground.
- the installation apparatus may be provided with a system for hanging the apparatus on or in the cable trays (hook systems, magnetic plate). This unit can easily be cascaded.
- the system is also equipped with a ring that holds the screwdriver in rotation.
- the design of the device also makes it possible to block the start of the power supply during installation and thus to perform other manipulations simultaneously.
- the present device is for that provided with a holding system without manual action maintained.
- the device is intended to be placed in the active position, and kept active while leaving the hands free to the user.
- the present device being here provided with a switch 150 of manual depression type, it is provided, in the direct vicinity of this pusher, a pivoting member 160 whose movable end can be placed in two different positions, one laterally shifted from the pushbutton 150, the other pressing on the same pushbutton
- Such a device is actuated after switching on the drive motor, by displacement of the holding member 160 in direct support on the push button 150, which thus remains in the depressed position.
- the device provides a technical solution, particularly with regard to the simplification of manipulations. Indeed, you can handle the device easily thanks to its small footprint, low weight and ergonomics.
