Description

The invention relates to mobile electrical distribution systems, which serve to supply current to mobile receivers and consist of wires mounted on supports, which are moved in the direction perpendicular to them by a current collector. In the proposed installation, the stands, for the purpose of their free movement through the ridges, are made in the form of spokes fixed in the hub, equipped with braces not closed with each other in full rim. The wires are passed through the hubs, and between the spokes, the conductive parts are reinforced, which direct the current collector around the part of the wire that passes through the hub.

The proposed installation (Fig. 1) consists of a rectangular frame / made of planks joined together by a spike or simply knocked down with nails. Closer to the ends of the frame are packed with a nail x short pieces of the planks 2, in order to form a bearing for the wheel axis. The latter consists of individual spokes 5 connected by crossbars 6 and allows using a network with such supports for working on the fields of growing tilled crops, since the length of the spokes 5 can be chosen such that when the network moves across the field the cross member 6 always falls as times between cultures.

Racks 7 and strut 8 support a square beam 9 into which the same tree is inserted, but with iron washers at the top and bottom, the stand / ft-Bottom is inserted into the corresponding hole of the beam 9, part of this stand has a rectangular section . An iron pin 7 / is inserted into the Stand fO, the cross section of which is rectangular at the bottom and the round one at the top. On pin 7 /, as on an axis, a part J2 can be rotated to attach the wire of beam 75 to it.

The method of connecting the wire-beams between themselves and with part 12 is indicated schematically in FIG. 1-2 (the holes for the connecting bolts in Fig. 2 are labeled 16). Part 2 is made of wood, paraffin-soaked, or another fairly good insulator. From the bottom, it has an iron washer 13 (Fig. 1) with a process 13a at the end diametrically opposite to the wire - the beam. If a sufficiently long bolt is inserted into the hole 14 shown at the end of this process and into its extension T14a in the body of beam 9, part 12 will not be able to rotate around pin 11 and therefore the longitudinal axis of the entire two-wheel stand will always be perpendicular to the longitudinal axis wire-beams, which can be useful during normal operation of the mobile network on the field.

When this section has already been completely processed by the mobile network using tools attached to it, and the network will need to be transported to another section, then with this design this can be done without disassembling the network into its component parts. For this, removing the pre-bolt from the hole 14 and 14a, raise the wire-beam 15 slightly, and the two workers easily turn the entire two-wheel stand so that its longitudinal axis is not across, but along the length of the network and the beams. In this position, the mobile network will be a very long but narrow strip that can move along its length along the narrowest rural roads, and the electric tractor (of course, together with the self-moving / transformer station ahead of it) will easily transport it, all at once or in parts, on, another site.

The wheel type for a single wire wire is shown in FIG. 3 and 4, where it is shown, in addition, the device of the .5 part, which simultaneously serves as the wheel axis and for electrically connecting the individual wire-beams into one continuous conductor. Axis 5 is fitted with a tube 7 forming the inner part of the wheel hub. The wheel itself consists of separate spokes 2, connected into one whole wheel (of the spokes) using parts 3 and rings 4. The drawing has four spokes, but of course there can be as many as possible. This type of wheel is convenient for operation.

on the floor of tilled crops and in general in row, sowing, like the type of two-wheeled stand. During the movement of an electric tractor or other electrified machine gun, the wheels or sliding elastic contacts of the current pickup slightly deviate to the right with the pointed part of the axis 5 from the linear axis of the cavity in the beam and are directed by it into the hole of the cavity 6 on the hub of the wheel formed by parts 3. When the collector spring when the electric tractor moves along will be sufficiently compressed, it will turn the wheel. Since the latter consists of knitting needles, It will obviously turn in this way by jerks by an angle equal to the angle between the knitting needles. This is precisely what is needed here, because, thanks to this, the openings of the cavity of the beam and the cavity on the bush 1b will always be facing each other. The parts 3 are electrically connected through the axis 5 and the sleeve 4 with the wire wires, and therefore the current is removed from them during the wheel sleeve bypassing with the wheel or sliding contact of the current pickup.

The inventor has developed a type of current collector in the form of a whole chain of wheels or contacts so long that its connection with the beams is not interrupted even during the bypass of the wheel, which makes it possible to completely isolate the guide parts 3 from the axis 5 without interrupting the current beams-wires were electrically connected to each other. This is done on the type of wheel-stand for two-wire wire-beams (Fig.). This type of wheel consists of individual wooden needles /, which are fastened with iron tape 2 with a tension bolt 3 into the whole wheel. Iron parts 4 are placed between the spokes. They come out of the spokes, because their length is equal to the length of the sleeve. The ends of the needles (which form the sleeve) are impregnated with iron or paraffin for better insulation. The wheel axis 6 simultaneously serves to electrically and mechanically connect in a single line the mobile network of separate wire-beams. As can be seen from FIG. 9, axis 6 consists of two metal (iron) segments separated by an electrically insulating layer (with a three-wire conductor, this axis will be

consist of three incomplete sectors). The construction of axis b is shown in FIG. 7, which is a view of the axis (part of the wire-beam) from above, but with the insulation removed from the top, so that the contact point of the axis with the metal body 10 of the wire of the beam can be shown. The axle segment is gradually thinned, but immediately after exiting the sleeve it has two thin wings 7 and 8, forming between them a "right angle." Bolted to them are two similar wings (of course, bare from the insulation) that are at the end of the beam-conductor. The connection of the second (lower) wire-beam is exactly the same as the top and, of course, the left crown of axis 6 is exactly the same. like the right one.

FIG. 8 that between the upper wing 5 and the same lower wing

axis segment laid board 11 of wood or other insulating material. This board, together with the end wings of the conductor-beam, forms a channel, directed. The beginning of the chain of the wheels or sliding contacts of the current collector to the opening of the kangiha formed by parts 4 on the wheel hub. The latter are isolated from the axle segments and conductors and are therefore not under voltage, but they are easily electrically connected to the segments and, moreover, separately from each other. as follows: the protrusion of the wheel hub together with the fastening tape 2 is destroyed, a relatively thin metal washer is put directly on the end of the hub, which is soldered or welded, on the one hand, with all the right (viewed from the center) by parts 4 and, on the other hand, with the upper segment of axis 6, but remains isolated from the other lower segment (for example, by cutting a part against the lower segment closer to the axis 4 cls). On the other side of the hub there is the same washer, but connected (welded) already with the left. parts and with the lower segment of axis 6, electrically isolated from the upper segment. Outside on both sides, washers are made of wood or other insulating material. The whole wheel engages eight (by the number of spokes) bolts through the entire hub in the middle of the hub parts of the spokes /, from one outer insulating plate to the other.

Similarly, one can construct such a wheel-stand and for three (or more) wired networks of the respective girder conductors. Since axis 6 consists of two segments with an insulating gasket, it itself is fastened with bolts with insulating sleeves and washers, which are best placed on the sinking part (Fig. 7). In all types of support wheels, the axis is one mechanical unit with the wheel, i.e. permanently connected to it and not detached from it even when disassembling the network.

The aforementioned lack of one-wheeled coupling stands (the need to disassemble them to transport the network to another area) is compensated for by the ease and simplicity of the design of these supports.
