    Electrical device for introducing a guide in a conduit.
    Object of the invention
    The device of the invention, as its own title indicates, is intended to facilitate the introduction as well as the removal of a guide in a conduit. This guide can be a cable gland of the type that is introduced through an electrical conduit, to subsequently drag the electrical cables of said installation, or it can also be a guide of the type that is introduced through of a drain pipe to unclog it.
    Background of the invention
    We are currently not aware of the existence of any tool, electrical or manual, that allows automating the entry of the guides, of the type indicated, through the appropriate conduit or channeling.
    For this reason, it is necessary to develop a new device that allows expediting the procedures that currently prove to be very laborious for the operator, having its use, as a first consequence, comfort and safety by reducing professional risks of the operator, its greater performance labor, lowering costs in facilities, as well as increasing competitiveness in the installation companies that adopt this mechanism.
    Currently, different types of guides are used to introduce them into the conduits intended for wiring electrical installations, whether underground or on the surface. Its diameter and length depends on the professional or domestic use for which the guide was purchased, as well as on the length of the installation to be implanted, modified or extended. Said guides basically consist of a cylindrical nylon cable of great resistance, with different lengths and thicknesses, which in their front part have a flexible and removable toe, which facilitates their advance along the interior of the ducts or pipes, as well as their curved areas, containing in its previous part an eyelet that allows to hold the cables that will replace the guide, once it is achieved that it finally accesses the destination registration box, from where it can be extracted together with the cables to be introduced in the installation.
    The most common guides are made of nylon, and are an irreplaceable tool for wiring in electrical installations, having great resistance to both thrust and traction, as well as great flexibility, which is essential so that, through its spherical toe, can follow the trajectories of the tightest curves. At the other end, the guide contains a quadrangular eyelet that allows the cables to be installed to be installed and by which these cables will be knotted, once the plastic cover has been removed in sufficient length to be tied directly through the inner copper.
    In the introduction of the guides we usually find that the conduits that contain the electrical installation already have several wires, have tight curves, splices or other defects that hinder the manual introduction of the cable guide, which entails some disadvantages:
    - Great effort is required in relation to the yields obtained.
    - Excessive labor time in proportion to the facilities.

    - Need for rotation of the guide in cases of jamming it, not being prepared for this purpose manually, leading to damage due to breakage, as well as the extreme discomfort of the operator.
    - Withdrawal from it to start new attempts when the previous ones were failed, sometimes proceeding to its introduction by the opposite circuit.
    - Seals, hooks as well as difficulty for the recovery of the guide, whose loss inside the installation can lead to the consequent need to open the installation through masonry processes.
    In the extraction of guides attached to the wiring that we intend to provide, we also have a problem as a great effort is required to overcome the resistance that this guide opposes, which in turn drags the cable (s) attached to it and that often need to be lubricated in order to have a certain performance against the effort involved in such an operation, especially when it comes to installations that consist of the introduction of several threads.
    Description of the invention
    The device of the invention consists of an electric tool whose purpose is to introduce without any effort on the part of the user a guide inside an electric or hydraulic conduction. Said tool takes the form of a gun or a conventional drill, which has a guide duct along it, which goes from end to end defining a conduit through which the cable guide introduced through the anterior area is passed through the end of the canyon This conduit has a drive mechanism of said guide at an intermediate point, close to the handle, which is actuated by an electric motor, whose operation is carried out by means of a switch located in the trigger zone.
    The guide dragging mechanism consists of two rollers, of which at least one of them has double taper, similar to a diavolo, in order to facilitate the passage of the guide during the assembly of the guide in the tool . This diavol-shaped roller is normally located at the bottom, since it is the one that directly receives the transmission of the engine through a pulley integral to it. The second roller, located parallel to the previous one, is normally placed above and the pressure exerted on the previous one is adjustable in order to ensure the drag of the guide through the compression exerted by both rollers on it. The upper roller has a groove in the center, thus being designed so that said roller fits perfectly on the lower roller, which implies a perfect clamping and transmission of the motor thrust to both rollers.
    Both rollers must have at least one outer covering with some flexibility in order to sufficiently compress the guide and ensure sufficient friction between the two that leads to sufficient thrust of the guide.
    At the end closest to the exit of the conduit through which the guide runs through the inside of the tool has a second set of drag rollers that are intended to ensure the straight line of the guide as it passes through the device .
    It is envisioned that this device is provided with a reversing mechanism of rotation, which is activated by a second push-button, which allows the guide placed in a conduit to be removed, even dragging the cable or cables to pass through it.
    In an alternative embodiment, it is planned to place a nozzle adaptable to the conduit through which the guide is to be introduced, especially useful when

    Machine works in the reverse direction, pulling the guide and dragging the cables, keeping this nozzle resting on the outlet duct.
    This device has the following advantages:
    - Immediacy in the introduction of the guides (in the case of new installations, since the drive of the guide mechanically by means of this new system, will obtain that result.
    - Possibility of speed regulation - fast-slow advance.
    - Adjustable, alternate and intermittent forward-reverse function in cases of high resistance, due to excess wires in an electrical installation for example.
    - Function of vibration or rotation of the guide for jamming cases, intended to cause sufficient movement so that the guide makes its way through the wiring in special cases without causing damage to it.
    - Guide removal by means of adjustable and intermittent reverse gear as well as fast or slow.
    - Disconnection of the guide without finishing the operation by previous or subsequent extraction by regulating the upper tensioners.
    Description of the figures
    To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, some descriptive drawings are attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
    Figure 1 shows a general view in side elevation of this device.
    Figure 2 represents a schematic view of the drive mechanism (5) of the guide (7). Preferred Embodiment of the Invention
    As seen in the figure, this device takes the form of a gun_ (1) or conventional drill, in which the barrel is hollow and incorporates a conduit (6) that runs from the anterior area, to the mouth of the barrel , with access from both ends, introducing the guide (7) with the tip towards the mouth of the barrel, after passing it through a drag mechanism (5) mounted in the anterior area. This mechanism is operated by means of a motor (2), with its corresponding reducer (3), and its operation controlled by means of a push button (4).
    The electric motor will have the corresponding power socket and optionally an adaptable connection to a battery. The electronic control board allows you to regulate your speed, as well as reverse your gear through a second button (14).
    The drive mechanism (5) is constituted by two rollers (18, 17) that rotate in parallel, one of them (preferably the lower one (18) receiving the motor transmission through a pulley (19), exerting the upper roller (17) pressure on the guide held between both rollers, pressure adjustable by means of a tensioner (9) located on the outside of the device and on the top of said roller, which will allow us to release the guide when separating both rollers, or adjust it in such a way that it allows us to firmly adjust the separation of said rollers to adapt it to the needs of the work to be carried out.The two rollers are made of a semi-rigid material, or are provided with a semi-rigid coating so that, in conjunction with the spring interposed between the screw (9) and the axis of this roller, ensure maximum support of the

    guide between both rollers, which will result in an optimal transmission of the motor force to the guide facilitating the absorption and adaptability of said mechanism to the guide without loss of drag capacity.
    The transmission of the movement from the gearwheel (3) that receives the transmission of the motor (2) to the drive mechanism (5) is carried out by means of a belt (15), which has an intermediate tensioner (16) which has mission to maintain sufficient tension in it and regulate said tension by means of a screw that has an intermediate spring that guarantees the tension of said belt at all times. Said tensioner (16) has two contacts which, together with the circuit of the switch (4) cut the current, if the belt is tensioned or tensioned outside the optimum operating range, as a result of a break in the forward or reverse of the guide as consequence of an eventuality such that a jam, overexertion above the capacity of the machine, breakage of the belt, etc ...
    Towards the outlet of the guide, a second guiding mechanism (8) is placed, whose mission is to keep the guide (7) straight along the tool, while running along the inside of the conduit (6). This mechanism is formed by two rollers of a semi-rigid material, or they are provided with a semi-rigid lining so that, in conjunction with the spring interposed between the screw (10) that presses the upper roller, they secure the fastening of the guide between them.
    The pad (11) present in a duct window (6) strikes the guide (7) as it progresses. The purpose of this pad is to impregnate the guide of some type of lubricant product, when it is necessary to compensate the frictions generated in the introduction or removal of the threads and the guide itself.
    It is also planned to place a removable or threaded nozzle (13) in the outlet of the guide that adapts to the conduit through which the guide is to be introduced, thus keeping the tool more easily supported during the positioning operation and facilitating the pulling of the guide during the extraction operation of its place of placement.
    It is also planned to place a mechanism that causes a vibration and / or rotation effect in the guide (7) for cases of jamming, this mechanism is similar to that of the hammer drills and it would be a second connection that acting around the guide (7) performs the vibrating movement, or that rotates it in one direction, or in reverse directions alternately.
    This device can also take a slightly different form than the one shown, which is more oriented towards introducing a guide through drainage pipes in case of clogging, resizing the engine capacity and dimensions of the device.
    For the operation of this device, it is first necessary to place the guide in the machine, inserting it from the back until it reaches the drag body (5), which adjusting the pressure in order to exceed it until it reaches the next mechanism of guided (8) and appear at the opposite end of the machine. Once the guide feeding operation has been carried out, we will proceed to adjust the pressure of the main and secondary drag body, observing if the advance of the guide is correct and we will proceed to regulate the forward speed and introduce the guide in the necessary duct.
    The guide is introduced into the corresponding duct by bringing the nozzle (13) to the inlet of the nozzle and operating the machine using the button (4). Once the operation is finished, and the guide has exceeded the destination mechanism box, we will proceed to introduce the previous part of the guide next to the destination mechanism box, by either of the two entrances of the machine in order to proceed to guide removal,
    already attached to the wiring to be introduced in the installation. The drive of the thread guide assembly will be carried out at low revolutions and if necessary, by means of the forward-backward or intermittent functions in said advancement, lubricating, if necessary, through the system that for this purpose is located at the top of machine.
