Abstract
In order to make rubber sleeve cable power supply and in the same time also can water supply, in cable's center arrange a water supply hose (1), power line which divided into two or three partingline (2,3) and three stakeout/control bonding wire (4) circle water supply hose in the same layer symmetrically.
Description
The present invention relates to this field of power supply of mobile electrical devices, can be applicable to the structural design aspect of flexible cable.Except that power line was given tunnel machinery power supply, this structural design also provided three strands of supervision/control combination heart yearns.
The Plastic-sheathed Cable of the heavy type of using during the power supply of down-hole mining engineering jumbo, for the mechanics protection to cable core, inside and outside respectively have a protective layer, is the tension braid that one deck is made up of wire between two-layer.With regard to existing gallery cable, this tension braid is made up of the twisted wire of copper wire and steel wire, constitutes the part of shielded type cable cross section at least simultaneously.Cable core itself is made up of three strands of stranded power lines, and its wedge shape space is three strands of prison/control assemble lines, power line and prison/control assemble line be each other symmetry status (list of references: DE-OS 2713385, DE-OS2619223).
Existing another kind of gallery cable is to arrange one pilot wire in cable central authorities, (list of references: GB-PS421073) in the power line that is divided into two stock lines around the pilot wire and one shielding conductor are stranded in one deck.
When using the coal-winning machine of underground mining engineering, except the needs gallery cable, also need a hose, provide cooling water by hose to the motor of coal-winning machine on the one hand, supply water to sprayer unit by hose on the other hand, with the moistening coal of adopting.Up to now, gallery cable and hose are pulled abreast by coal-winning machine.Used hose external diameter is about 30 millimeters, and must bear the work pressure of about 25 crust safely.
Existing excavator power supply adopts the Plastic-sheathed Cable that can reel.Wedge shape space between the stranded power line of this cable has also been arranged the enhancing flexible pipe, thus cooling agent can be pressed into thus by.Cooling agent pass through protecting that part of Plastic-sheathed Cable on cylinder, make it unlikely overheated (list of references: DE-PS902988).
Task of the present invention is that necessary hose of use mobile electrical devices and flexible cable is integrated, and the pipeline of simplifying mobile electrical devices thus pulls mode, thereby, make and have the following prior art structure that belongs to (that is: shown in this Figure of description, its power line and three strands of prison/control assemble lines are stranded symmetrically around cable core, cable core is surrounded by three layers outward, i.e. sheath, an outer braid and the outer jacket made by wire of sheath) mobile electrical devices power supply flexible cable, it is characterized by: cable core central authorities are water supply hoses, power line is divided into two strands or three stock lines 2 respectively, 3, described separated time 2,3 and prison/control assemble line 4 are jointly in water supply hose 1 is stranded in one deck.
In order to solve this task, the present invention arranges a flexible pipe in cable core central authorities, and power line is divided into two or three stock lines, and separated time and prison/control assemble line is in rubber tube is stranded in one deck mutually.
The water supply hose of being arranged has determined the structure of cable.In this structure, because power line is divided into a few stock lines, the cable section has obtained optimum utilization.In order to be formed uniformly the mechanical characteristic of cable as far as possible in tangential direction, desirable and the identical or approximately uniform size of power line separated time external diameter when selecting the diameter of prison/control assemble line.For example, can realize this requirement by the thickness of insulating layer of suitable increasing prison/control assemble line.The structural design of prison/control assemble line preferably will satisfy this point, and this mentions in list of references DE-OS2619223.
Sub power source line is the conductive section size that the mode of separated time depends on power line, also depends on the diameter of water supply hose.When the conductive section of power line and the diameter of water supply hose were all big, power line should be divided into three stock lines, and it is just enough to be divided into two stock lines in general.When considering to wrap additional braid and outer jacket for mechanics outside the water supply hose, also can consider power line is divided into three strands.
Accompanying drawing is an embodiment of novel flexible cable.
Accompanying drawing has provided the cross section of the gallery cable of combining with water supply hose, and water supply hose 1 is arranged in the central authorities of cable.Three strands of power lines of cable respectively are divided into separated time 2 and 3 respectively, and like this, this six stocks line and prison/control line 4 is twisted into one deck around water supply hose 1 symmetrically.Per share separated time is made up of one lead, an insulating barrier and a conductive layer.Per share prison/control line, structure according to list of references DE-OS2619223 proposition, form by following three parts: with 5, one insulating barriers of thickening in the present embodiment 6 in core and one concentric pilot wire 7 that wraps in conductive layer on the insulating barrier, external belt one deck extrusion molding of a supporting-line, a plastics covering and one concentric pilot.(be equipped with in the centre under the situation of film braid 8) above the stranded core is sheath 9 and outer jacket 11.The wire sheathing of being made by the twisted wire of copper wire and steel wire 10 is placed in the outer jacket, has constituted the screen of cable simultaneously.
Claims (3)
