Cable saddle for heavy * cables

The present invention relates to a cable saddle for heavy cables for fastening to concrete or struts of the cable duct, with a saddle shell for carrying the cable.

Such cable saddles are known and used in large number, which are used to carry the pulled into cable ducts Cables are used.

A major disadvantage is that heavy cables cannot be pulled in on the saddles.

So the pulling in of such cables has so far been about vertical Support rollers attached to compression struts, which are attached approximately at the desired height, performed, and then the cable, if it is adjusted to the required length, using cranes or other lifting tools is placed on the cable saddles.

The cable pull-in is usually also at the bottom of the cable duct Carried out on support rollers, with the cable then up to the cable saddles by means of lifting tools must be raised and inserted.

Once the cable has been drawn in and rests on the saddles, it is no longer possible to change the Bring about cable position.

The object of the invention is to avoid the disadvantages of the known, in particular a cable saddle of the to create the type described, by means of which the cable can be drawn onto the saddle without additional tools can and where later changes to the cable position can be carried out.

According to the invention, this is primarily achieved by that at least one support roller that protrudes beyond the surface of the saddle shell and is attached to the saddle shell is provided and that the support roller is rotatably mounted for easy pulling in of the cable.

This makes it extremely easy to pull the cable into the cable duct on the cable saddles themselves made possible without the need for special tools or lifting columns.

With the cable saddle according to the invention it is also easy to change the cable position after it has been pulled in, without having to remove the cable from the cable saddles.

The invention can be implemented advantageously if there is a protruding support roller at each end of the saddle shell or a support roller is arranged in the middle of the saddle shell.

In a further embodiment of the invention, the saddle shell rotatably arranged on a joint and the support rollers can be attached to the saddle shell in a movable and removable manner.

As a result, it can be achieved, on the one hand, that at the beginning of the pulling-in process, the beginning of the cable has an almost seamless transition is absorbed by the saddle shell, as it can rotate according to the load; on the other hand can the support rollers are removed from the cable saddles after the cable has been pulled in, so that the cable is on each Cable saddle can be rigidly attached.

Advantageously, a cable clamping device can be arranged on the saddle shell, whereby an additional Attachment of the cable can be achieved.

The invention can be implemented particularly advantageously if at least one for lateral support of the cable Removable lateral guide roller attached to the saddle shell is arranged.

In order to use the cable saddle with simultaneous horizontal and vertical deflection of the cable, the saddle shell can be tubular and trumpet-shaped at both ends to guide the cable on all sides, the saddle shell can have a cable feed-through opening, with at least three evenly around the saddle shell the circumference of which arranged support rollers can be attached and finally the saddle shell can be rotatably mounted on all sides by means of a ball joint.

As a result, cable routing on all sides is achieved in an optimally simple manner, with the cable saddle as a result of the ball joint adapts to any cable deflection. Jamming or kinking of the cable in the saddle shell is reliably prevented according to the invention by the trumpet-shaped design on both sides. This will also be the case simultaneous horizontal and vertical deflection of the cable guaranteed.

In an advantageous embodiment of the invention, at least three support rollers can be arranged at each end of the trumpet-shaped saddle shell, whereby a simple and reliable Cable routing can be reached during the cable pull-in.

The support rollers can advantageously be detachably attached to the saddle shell.

As can be seen, the technical progress and the inventive content of the subject matter of the invention both by the new individual features and in particular by the Combination and sub-combination of all individual features that are used are guaranteed.

The invention is explained in more detail below in various exemplary embodiments with reference to drawings. Show it:

FIg. 7 shows a section along line VII - VII of the cable saddle in FIG. 6th

Figure 1 shows a cable saddle for cable pulling in with a saddle shell 1 for carrying the electrical cable 2. The Saddle shell 1 has an opening 3 in the middle, in which a support roller 4 by means of a not shown Fastening device is arranged movable and removable.

The support roller 4 protrudes slightly over the surface of the saddle shell 1, so that the cable 2 as a result of Support rollers can be moved without touching the saddle shell 1.

Figure 2 shows a cross section of the cable saddle, from which the support roller 4 and the saddle shell 1 can be seen are. The cable 2 here only rests on the support roller 4.

When the cable has been drawn in and is in its final position, the support roller is taken out to remove one To obtain a cable saddle according to FIG. 3, in which the cable 2 rests on the saddle shell 1. The support rollers can be easily removed and reattached even when the cable saddle is loaded. As a result of weight will the cable held securely on the saddle shell; however, it can also be attached to the saddle with conventional clamping devices secured.

FIG. 4 shows a longitudinal section of a cable saddle with two support rollers 4, 4 ', which are each attached to one end of the saddle shell 1 by means of fastening devices (not shown) are arranged. This embodiment differs from the one described above insofar as there is no opening in the saddle shell that would impair the strength is provided.

The joint 5 and consequently the rotatability of the saddle shell 1 ensure that the cable 2 is uniform presses on the saddle shell and vice versa. Since the cable 2 can be pulled by means of a rope, not shown Inevitably, at the connection point between the soil and the cable, there is a jump in the durometer, usually in the form of a The trump card is to be recorded, which, however, is due to the rotatable arrangement of the saddle shell 1 as a result of the joint 5 is compensated so that no jamming of the cable can occur. *

The embodiment of the cable saddle according to FIG. 5 has, in addition to the support roller 4, two lateral guide rollers 6 for the horizontal deflection of the cable. These guide rollers 6 are also removably attached to the saddle shell and can also be arranged on cable saddles with two support rollers.

In Figure 6, a cable saddle with a trumpet-shaped saddle shell 1 is shown. The saddle shell has a passage opening 8 through which the Cable 2 can be passed through. So that the cable 2 can be moved simply and easily through the feed-through opening 8 when the cable is drawn in, are at the ends of the Trumpet-shaped saddle shell each four support rollers 4 attached in such a way that the cable 2 is not on the saddle shell is applied. After the cable has been pulled in, to securely hold the cable in the cable saddle, the support rollers 4 are removed. The saddle shell 1 also has a ball joint 7, by means of which the cable saddle can deflect any cable, can adapt in particular simultaneous horizontal and vertical deflection of the cable.

As can be seen from FIG. 7, the support rollers 4 protrude slightly into the feed-through opening 8, so that the cable is definitely not in contact with the saddle shell.

The ball joint 7 has a fastening device, not shown, by means of which the cable saddle is fastened to the concrete or to the struts of a cable (not shown).

The embodiments described above are just very special and realize particularly economical compared to conventional cable saddles; All the more so because both the support rollers and the lateral guide rollers can be removed from the cable saddles in the operating state and used for further cable pull-ins. Obviously, a different design of the rollers or of the entire cable saddle is therefore easily possible without departing from the scope of the invention.
