    • 专利摘要:
    A duct section serves as part of a supply system for supplying electric power or a pressure medium to a mobile appliance and especially to a mining machine in a mine working where protection against explosion or fire is necessary. The duct section has a wall with a longitudinal slot therein and pick-up engages in the slot to collect the electric current or pressure medium. The slot is sealed with the aid of thin flexible sealing strips held flat against the inner and outer surfaces of the slotted wall. The pick-up is shaped to progressively deflect the strips away from the slotted wall to permit the passage of the pick-up and maintains the interior sealing with the aid of further seals slidable engaging with the slotted wall over the region where the strips are deflected.

    At the bottom of the hollow part of the sealing under the movable element and rejected from the pipeline. In addition, shrink screws are installed between steel tapes, and pressure tapes are installed on the tapes on the side of the upper and lower hollow parts of the sealing movable element, and the intermediate part of the sealing movable element is made in the form of a double-sided wedge. FIG. 1 shows a food line in longitudinal section; in fig. 2 shows section A-A in FIG. one; in fig. 3 is an isometric view of the intermediate portion of the sealing movable element; in fig. 4 is a section BB in FIG. 1. The line feed consists of a pipeline 1 having a box profile that is assembled from separate links connected elastically or rigidly, and is made with a terminal 2 through which the sealing moving element 3 is passed with a cable 4 passing through it connected to the current collector 5, designed to interact with the current-carrying tire 6. The movable element 3 is connected to a movable machine. To seal the slit 2, an elastic seal is provided, which consists of two elastic sealing lengs 7 and 8, the width of which is larger than the width of slit 2, and they are made of thin wear-resistant steel material. Tape 7 is adjacent to the bottom of the pipeline 1 n forms an internal jTuiOTHeHHe, which seals the slot 2 along the entire length and width. Tape 8 forms an outer seal, sealing the slot 2 from the outside and serving mainly as a dustproof seal. Both sealing tapes 7 and 8 are held in position of the seal with the help of permanent magnets 9, which are reinforced along slot 2 of conduit 1 and are located on both sides of slot 2 between sealing tapes 7 and 8. The sealing element 3 is located inside the conduit 1 , the upper hollow part 10, and installed outside the pipeline 1, the lower hollow part 11, connected by an intermediate part 12 installed between them, passing through the slot 2. The upper part 10 passes along the sealing tape 7 and covers it it also has a cavity facing the slot 2, into which the rent 7 is diverted. On the side facing the lower step of the pipeline 1, the upper stitch 10 of the element 3 has a seal, which consists of spring-loaded elastic gaskets 13, which the upper part 10 of the element 3 is flattened in its IE9 4 rim zone, covering the inner space relative to the lower wall of the pipeline 1. The intermediate part 12 of the element 3 has an H-shaped profile and is made in the form of a double-sided wedge with surfaces tim 14 and 15 converging at ends. The gap 12, which is located in the inner space of the upper part 10 of the element 3, passes by its profile vertical wall 16 through the slot 2, both sealing tapes 7 and 8 being rejected due to the sliding surfaces 14 and 15 into the inner spaces of the upper part 10 and the lower part 11 elements 3. The lower part 11 of element 3 also has on its surfaces covering the inner space elastic peripheral sealing gaskets 16, which are tightly attached to the outer surface of the pipeline 1 and due to this An outer seal of the movable element 3 is formed, which seals the slot 2 on the opposite side in the opening area of the flat seal. The seals 13 of the upper part 10 of the element 3 form the inner seal of the element 3, which seals the slot 2 in the opening area of the flat seal. The seals 13 of the upper part 10 of the element 3 form an internal seal of the element 3, which seals the slot 2 and the opening zone of the flat seal inside the pipeline 1. This ensures reliable sealing of the pipeline 1 also where the movable element 3 opens the flat sealing tapes 7 and 8. On the upper part 10 is located clamping device 17, consisting of a spring loaded lever, which roller 18 rests on the upper wall of the pipeline 1 and at the same time presses the upper part 10 of element 3 against the bottom wall t pipeline 1 and holds it in this position. The upper part 10 and the lower part 11 have in their internal cavities pinch rollers 19 and 20, which hold the sealing tapes 7 and 8 in front of the intermediate part 12 holding them, or return the tape to this position beyond the intermediate part 12. Electric cable 4 for removal of current passes from the outside through the side of the element 3 into its inner spaces to the contacts 5. The cable 4 is sealed by sealing: 21. A pipe 22 is also connected to the element 3 for supplying a protective gas, for example nitrogen, which passes through black of member 3 and enters the conduit. 1 near the place of collection. Through conduit 22, the protective gas enters conduit 1, and only the leakage loss needs to be compensated.
    Due to its good sealing qualities, the supply line can be used as a pneumatic or hydraulic pipeline for supplying pressurized media.

    Claims (4)
    [1]
    1. Power lines, in particular for electricity supply in hazardous areas, for example
    in the mines, comprising a conduit busbar tubing, provided with a slot, through which a sealing {1I) movable element is passed with a cable connected to the current collector through it, and the slot is insulated by an elastic seal, which in order to improve the reliability of the supply line by improving its sealing, the sealing movable element is made of the upper hollow part located inside the pipeline and the lower hollow part installed outside the pipeline, connected between an intermediate part, and is pressed against the slot by a clamping device, wherein the elastic seal is placed inside the sealing movable element, and between the slit and the upper hollow part of said movable element there is a single spacer and between the center and the hollow part of said movable element located another sealing gasket.
    [2]
    2. The power lines according to claim 1, so that the elastic seal is made of two steel tapes, one of which is placed inside the upper hollow part of the sealing movable element and rejected inside the pipeline, and the other is placed inside the lower hollow part of the sealing of the movable element and rejected from the pipeline.
    [3]
    3. Line food on PP. I and 2, which means that magnets are mounted between the steel tapes, and the pressure rollers are mounted on the tapes on the side of the upper and lower hollow parts of the sealing movable element.
