Abstract

The invention relates to a guiding device for guiding a cable, having two receiving limbs arranged in a V-shape or U-shape relative to one another, which span a closable receiving area for the cable, with the cable resting at least in sections on both receiving limbs, at least two rollers, with each receiving limb at least one roller is arranged in such a way that the axis of rotation of the roller extends coaxially to the longitudinal axis of the receiving leg, and a fastening device for fastening the guide device, the fastening device being designed in such a way that the guide device can be rotated and/or pivoted in the fastened state.

Description

The invention relates to a guiding device for guiding a line.

The pulling of lines, e.g. cables, has so far been cumbersome and tedious, especially if one or more corners, for example in a cable duct, have to be negotiated.

To change direction, e.g. at a corner, one worker must be used per direction change position. If this is not available, the full length of line must be pulled to this point, where it may be routed down to the ground, then re-threaded and pulled to the last manned turn position.

The use of previous solutions is primarily suitable for support on straight stretches. When changing direction, when pulling laterally, downwards or upwards, the cable can easily grind or become jammed on a frame and/or a pulley. Also, conventional devices are mostly limited to pulling individual lines.

Depending on the direction of pull, the guide devices must be rotated and/or mounted in the direction of pull. The attachment turns out to be complicated or there are no attachment options available. In addition, the brackets are comparatively unstable.

The installation is intended to be horizontal or vertical and 90° to the edge of the cable tray. A different alignment is only possible, if at all, using additional components.

The train options are limited overall.

It is therefore an object of the invention to create a guiding device and a method for guiding a line, wherein the guiding device can be used in a variety of ways with simple assembly and/or jamming of a line is prevented.

This problem is solved by the objects and the method of the independent claims.

The guiding device is designed to guide a line, e.g. when laying the line. Also preferably several, e.g. 2, 3, 4, 5 or more lines can be routed at the same time.

The invention also relates to the use of the guiding device for guiding one or more lines. The line is preferably guided temporarily during laying and is not permanently arranged in the guiding device.

The term "guidance" is to be understood broadly and also includes deflection, a change in the direction of pull and/or stopping. The guide device can be designed, for example, as a deflection device.

The term "line" is also to be understood broadly and also includes a cable, a rope, a hose and/or a pipe.

The guide device has two receiving legs arranged in a V-shape or U-shape with respect to one another, which span a receiving area for the line that can be enclosed, preferably completely or partially.

The receiving legs may preferably comprise or consist of a metal material such as steel. For example, the receiving legs can be designed as round steel.

The receiving legs can preferably be arranged in one plane. Alternatively, these can also be offset from one another, e.g. on different levels.

For example, the receiving legs can be connected to one another and/or formed in one piece, e.g. as bent round steel.

The receiving area can, for example, be triangular or rectangular, e.g. rhombic, or can comprise a corresponding section. The receiving area can also be, for example, polygonal, e.g. pentagonal or hexagonal, semicircular, circular or oval.

The receiving area can preferably be openable at least in sections for inserting and/or removing the line. If the line is accommodated in the accommodation area, the accommodation area can be enclosed or surrounded, preferably completely, for example by means of struts. In the enclosed state, safe guidance is made possible without the cable being able to leave the recording area unintentionally.

The line rests, preferably simultaneously, on both receiving legs, at least in sections.

The line is preferably routed on the inside between the receiving legs.

The guide device has at least two rollers, at least one roller being arranged on each receiving leg in such a way that the axis of rotation of the roller extends coaxially and preferably concentrically with the longitudinal axis of the receiving leg.

The rollers can be designed as ball bearings, for example, or can include a ball bearing.

The line preferably rests on at least two rollers, at least in sections.

The rollers are driven passively. A movement of the cable also sets the rollers in motion. Preferably, the rollers rotate at the same rotational speed when the line is pulled. The cable does not drag sideways over the rollers.

A receiving leg can have several rollers which can rotate independently of one another. If several cables are pulled at the same time, the rotational speed of the rollers can be adjusted individually to the speed of the cables. This can result in different rotational speeds if the cables do not move in a straight line but, for example, in curves over the rollers.

The guide device has a fastening device for fastening the guide device, the guide device being rotatable and/or pivotable in the fastened state. The turning and pivoting can preferably take place in different planes.

The fastening device is designed to enable rotation and/or pivoting in the fastened state, e.g. while the line is being guided. For example, the fastening device is designed as a hanging fastening device. The fastening device is preferably arranged above the receiving legs. The guide device is held, for example, from above.

The rotatable and/or pivotable attachment of the guide device enables the guide device to be aligned independently, preferably in almost any direction. For example, a change of direction, e.g. a train or a deflection between 0° and 180°, is possible. The change in direction can be 90° horizontally, for example. In addition, all spatial changes of direction are possible. Simultaneously with the bend in direction, for example, the level and/or the altitude can also change. Furthermore, acute angles, for example up to a 180° turn, can be implemented.

The guide device can therefore be used in a variety of ways with simple assembly.

The simple, flexible and/or movable fastening device ensures, for example, an independent alignment of the guide device in the direction of the bisecting line, e.g. in three-dimensional space. The guide device aligns itself preferably in an optimal position in the direction of the bisecting line in three-dimensional space. Clogging, jamming and/or grinding of the lines or rollers that do not run in the direction of pull can be avoided in this way. Furthermore, a power-saving pulling of the line is made possible. In addition, the guiding device according to the invention is light and handy.

The personnel costs are also kept low, since a guide device according to the invention can be used instead of a worker for changing the direction of a line to be pulled at the corners.

Further developments of the invention can also be found in the dependent claims, the description and the accompanying drawings.

According to one embodiment, exactly two receiving legs are provided. The crossing point of the accommodating legs, that is to say the point so to speak, is preferably oriented downwards in the unloaded state and/or is aligned in accordance with the pulling direction.

The line preferably runs over the crossing point. There, for example, the rotatably mounted rollers meet. The line can be routed, e.g. diagonally, in the tip or corner of the receiving leg.

Because only two receiving legs are provided, the production, repair and/or maintenance costs can be kept low.

Alternatively, 3, 4, 5, 6 or more mounting legs are possible.

According to a further embodiment, each receiving leg has a plurality of rollers. For example, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more rollers can be provided per receiving leg.

Preferably, each receiving leg has the same number of rollers. The rollers can, for example, be constructed in the same way.

Alternatively, the number and/or shape of the rollers can differ.

According to a further embodiment, the receiving legs enclose an angle of between 45° and 135°, preferably between 80° and 100°.

The angle can be, for example, between 85° and 95°, for example 90°. It is preferably an acute angle.

According to a further embodiment, the fastening device is arranged on a side opposite the crossing point of the receiving legs. The fastening device preferably holds the guiding device from above. However, lateral attachment is also possible.

According to a further embodiment, the receiving legs are connected to the fastening device via struts. For example, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 or more struts are provided.

In a preferred embodiment, exactly two struts are provided. Each strut can be assigned to a receiving leg and/or connected to the receiving leg. The struts preferably have no rollers.

The struts are preferably arranged in a V-shape or U-shape relative to one another. For example, the struts can be connected to one another and/or formed in one piece.

The struts are preferably oriented opposite to the two receiving legs. The crossing point of the struts, so to speak the tip, is preferably oriented upwards in the unloaded state and/or is aligned in accordance with the direction of pull.

The struts and the receiving legs preferably completely enclose the line in the received state. In this case, for example, exactly two struts and exactly two receiving legs can be provided.

According to a further embodiment, at least one connection between a strut and a receiving leg is detachable. For example, both connections can also be detachable, or exactly one.

Alternatively or additionally, one strut or both struts can also be detachably connected to the fastening device.

The connection can preferably be a hook-in, Velcro, clamp, clamp, plug-in, snap-in, magnet, pin and/or screw connection.

As a result, a detachable connection between a strut and a receiving leg or a strut and the fastening device can be created in a simple manner. For example, the guiding device can be opened laterally and/or diagonally.

The connection or the opening and/or closing can preferably take place without tools. This ensures that the line can be quickly inserted and/or removed from the receiving area.

According to a further embodiment, the fastening device has a joint. A plurality of movable bearings can preferably be provided. As a result, the guide device is extremely mobile and flexible. For example, this can be rotated, preferably freely, in all directions. The angle can preferably be changed when a line is pulled. The alignment of the fastening device adjusts itself automatically. A line or lines can be diverted to varying angles.

According to a further embodiment, the fastening device has an eyelet, a carabiner, a shackle, a hook, a universal joint and/or a cardan joint. As a result, the guide device is extremely mobile and flexible. For example, this can be rotated, preferably freely, in all directions. The eyelet can, for example, be connected to the joint and/or form a unit.

The angle can preferably be changed when a line is pulled. The alignment of the fastening device adjusts itself automatically.

The guide device can be attached quickly and easily using a carabiner. The carabiner can be, for example, a snap carabiner, a twist lock, trilock, ball lock or screw carabiner. Furthermore, several carabiners can be provided for redundant attachment.

The invention also relates to a guiding device, preferably according to the invention, for guiding a line, having two receiving legs which have a closable receptacle area for the line. The receiving legs can be arranged in a V-shape or U-shape relative to one another, for example. The receiving legs can preferably be arranged in one plane. Alternatively, these can also be arranged offset to one another.

The line can rest at least in sections on at least one of the two receiving legs.

The guide device has at least two rollers, with at least one roller being arranged on each receiving leg in such a way that the axis of rotation of the roller extends coaxially with the longitudinal axis of the receiving leg.

A fastening device for fastening the guide device can optionally be provided, with the guide device being rotatable and/or pivotable in the fastened state. Alternatively, the guiding device can also be rigid when fastened.

The guide device has an anti-jamming device to prevent the line from getting jammed. The jamming protection can, for example, deflect the line like a deflector wedge and thus prevent jamming, for example when aligning the guide device or when the tensile force is reduced and the guide device swivels back into the starting position. Otherwise a line could be pulled between the possibly sharp edges of the rolls, jammed and/or damaged.

The receiving legs can be connected to one another, for example, via an anti-jamming device.

The anti-jamming device is arranged rigidly on the longitudinal axis of at least one receiving leg or forms part of the receiving leg. In contrast to the rollers, the anti-jamming device preferably does not rotate relative to the longitudinal axis.

For example, the anti-jamming device can be screwed, welded, riveted and/or jammed to the receiving leg. A plug connection is also conceivable. Alternatively, the receiving leg can form the jamming protection.

The anti-jamming device can, for example, be arranged on exactly one receiving limb or form part of exactly one receiving limb. Alternatively, the jamming protection can also be arranged on both receiving limbs or form part of both receiving limbs. For example, the two receiving legs can each be designed with one half of the jamming protection, e.g. left and right or front and rear, which are then connected to one another, for example.

The anti-jamming device is adjacent to at least one roller in the axial direction. For example, the anti-jam device connects to the end face of an outermost roller.

To a certain extent, the anti-jam protection forms an extension of the roll. A possible gap, e.g. between adjacent rollers of different receiving legs, in which a cable could become jammed, is filled by the anti-jamming device.

Alternatively, the anti-jamming device can be arranged rigidly between the rollers, preferably in an area in which the line is not routed and/or outside the receiving area. For example, the protection against jamming can be provided in an area in which the receiving legs or projections of the receiving legs intersect.

Jamming is preferably prevented before, during and/or after the alignment or pivoting back of the guide device.

The protection against jamming can preferably be shaped in such a way that the risk of damage to the line is reduced or eliminated. For example, the anti-jamming device can be at least essentially cuboid, cylindrical and/or spherical.

The anti-jamming device preferably has the same diameter as the roller. For example, the jam protection can be rounded, e.g. on the side. In this way, it does not get caught in a cable duct, for example. Other lines are not damaged either.

The invention also relates to a method for guiding a line, comprising a guiding device according to the invention, in which a line is accommodated in the receiving area and the receiving area is completely enclosed.

For example, a strut can be connected to a receiving leg or a strut can be connected to the fastening device in order to close the receiving area.

Depending on the direction in which the cable is pulled, the guiding device aligns itself. The guiding device can rotate and/or swivel when fastened.

An anti-jamming device can preferably prevent a line from becoming jammed when being pulled.

All embodiments and components of the devices described here are preferably designed to be used according to the method described here. Furthermore, all of the embodiments of the devices described here and all of the embodiments of the method described here can be combined with one another, preferably also detached from the specific configuration in the context of which they are mentioned. For example, a guide device according to the invention with two V-shaped or U-shaped receiving legs arranged relative to one another can have jamming protection. A combination of rotatable and/or pivotable attachment and anti-trap protection is preferably possible.
