Description

other and also do not concern a cable protection conductor. The same applies to the other supporting devices available in the literature for protective ducts of electrical lines and to the cable paths "Wire-Ways" made of prefabricated metal ducts or channels provided with lids, in connection with the latter it is also stated in the literature that they can only be used where they cannot be mechanically damaged. On the other hand, a cable protection derivation of the specified type, to which the invention relates, also serves to protect cables, which are otherwise freely laid, from mechanical in areas at risk. To protect damage from entering Gabeis · -iplet, other electric vehicles, etc. Hierar- ι are M.:h no cable conduits au <= Kun ** ion or ί not metal. Devices that the * ..; '-rtiutz have since been used by Beuic ^ w-.osser or! Electrician made from thick-walled F 'icn in place and Si-He. These permissions are time consuming and require an i'.o. ■ ·· effort.

Furthermore, by the same reference n'.ch prefabricated Hi'.fsrinnen and Sonderkanäic for electrical cables known, which are the ..en, closed Sliding channels between distribution and control panels arranged in layers in commercial buildings to build. However, these auxiliary channels and special canals can no more than those at the end The underground ducts described in the reference provide suggestions for design and training give a cable protection conductor of the type specified above.

The protective pipes used for such Kabelschutzable'tungen are usually galvanized pipes whose Ornament · ί ing through on the spot you ^r. 'Hge- ^";. Ihrte Ben oeitungsvorgMnge as Zi""' - '.- n and turn destroyed so that condensation can cause corrosion of the pipes.

The invention has the object of providing a Cable protection derivation of the type specified at the outset from components that can be assembled in a modular manner to be able to work quickly and easily without having to call on specialists.

The solution to this problem is according to the invention that the cable discharge through each Prefabricated in various lengths and kept in stock, which can be assembled in a modular manner Components is formed, uie from one on the top or bottom of the cable tray or -trough substantially transversely to the longitudinal direction of the same mountable pipe holder in the form of a tubular holding or guiding device for the cable or cables to be protected, one at one end of the pipe holder, possibly indirectly via an essentially straight one Protective pipe section of a certain length to be fastened pipe bend, preferably with a right-angled Bend, with the pipe bend and easily connectable additional protective pipe sectioncii and optionally a formwork carrier of a certain length which can be attached between these for arrangement various switches and one on the floor, e.g. next to an engine or on the Motor to be fastened tubular, for the formation of a Kabelausgariges for unilaterally open floor holder exist and apart from the switch carrier with one another by means of dimensionally stable pipe clamps of the same type are connected with unilateral tension, each with a about half the circumference extending central separating slit are provided.

In a cable protection conductor assembled in this way according to the invention, the can The pipe bracket arranged on the cable ladder or cable tray is also designed to be pivotable in the horizontal plane so that the pipe holder depending on the direction in which the cable is to be led away, can be adjusted. The pipe bend and the straight protective pipe sections can be commercially available Be parts that can be kept in stock in certain sizes or lengths so that the cable Sv.'vatz derivation can be adapted to local conditions. The one to connect the pipe bend with the straight protective tube sections and to connect the last protective tube section to the Ao floor holders are used for dimensionally stable pipe clamps can 1 have a relatively large length and allow a good adaptation to different parts to be connected and a perfect joint connection. the Switch carrier can also be kept in stock in different lengths and depending on the choice of Length for straight protective pipe sections in each Height to be connected to these and arranged. The switch carrier preferably consists of two irn Basic parts arranged at a distance from each other, shawl-shaped in cross-section and a connecting them, in cross-section approximately semicircular guide tube for the cable on the back forms a protective jacket and the connected straight protective tube sections together with the shell egg-shaped base parts offers a firm hold. In this way, on the one hand, damage to the cable is avoided and, on the other hand, it is made possible that the cable wires on the switch carrier, as this is open at the front, to the various switches can be guided. Lateral longitudinal flanges are provided on the guide tube to fasten the switches arranged, the si id provided with mounting holes for the switch by means of screws. The Bodenhaitcr serves to lead the cable out of the cable protection conductor to a motor, a machine or the like. Preferably, all parts of the cable protection conductor can consist of galvanized steel, whereby an increased service life is achieved, since the galvanizing the harmful influence of Makes condensation ineffective.

A cable protection cable corresponding to the invention * 'jng can be produced quickly and easily by unskilled workers using the modular principle. All parts of the cable protection derivation have a simple design that allows for a rational installation and stockpiling of the parts is possible. These parts can be used for different pipe dimensions be provided.

^ _R The straight protection preliminary ^k "mentioned above sections 29 and 30 are used in connection with the pipe bend 25 for Hcruntcrfiihrcn of the cable to the engine or other engine 2 and can be ι in, different standardized lungs kept in stock between the straight Schutzrohrabschni. LCN 29 1 and 2, a switch-IrUgCf 32 is arranged, which is used for fastening a wide variety of switches. The switch carrier 32 can also be kept in stock in various lengths of two shell-shaped baselines 33, which are spaced from one another and connected to one another by an approximately semi-circular guide tube 34. The guide tube is provided with lateral longitudinal flanges 35 in which fastening openings 36 for fastening the switches are arranged open and serves to school / the cable from behind en are therefore individually guided to the shoulders, which are fastened to the flanges 35 of the switch carrier 32 by means of the fastening openings 3 * and associated screws. At the two ends of the switch carrier, the cable is firmly encompassed by the one base 33 and the guide tube 34.Since the straight protective tube sections 29 and 30, as already noted, can be installed in different lengths, the switch carrier 32, which itself can also have different lengths, at any height between the pipe bend 25 and the ßcJershaker 3! to be ordered

As already mentioned, the cable derivation according to FIG. 2 between the Rohrhalterung 10 and the pipe bend 25 also be given away with a straight protective pipe section 37, the L _u .igc

depends on the Qüerabätänd the engine 2 or the other machine, in plan, is set up by the cable tray I. In such a case there is «25 at the upper end of the pipe bend an additional pipe clamp 38 of the already bcschric bencn training arranged, each half the one end of the straight protective tube section 37 and the adjacent upper end of the Rohrbogcns 25 and connects these parts together. the Pipe clamp 38 can be suspended by means of a suspension element 39

ts, which can also be kept in stock in different lengths.

The lower pipe clamp 27 connects the lower straight protective pipe section 30 to the floor holder 31. This consists of a Factory or other industrial building Lowing anchor plate 40 and a vertical pipe guide 41. This is in the lower part in cross section only semicircular, so that it is too open to the engine or the machine 2 so that the or the cables or cable wires can be connected unhindered. As can be seen from FIG. 7c, the vertical protective tube section is shown 41 can be arranged so as to be rotatable with respect to the anchor plate 40.

If necessary, the cable carrier 32 can also be used as a cable outlet, in which the cable connections for the motor or the machine are in different heights can be arranged. With such a cab output you can as well as

_3S, with the cable outlet formed by the broom holder 31, several cables can also be fed and connected.
