Large-power single-pole winding-type seamless sliding-contact line

Abstract

The invention relates to a large-power single-pole winding-type seamless sliding-contact line, which comprises a conductor and an insulator, wherein the section of the conductor is I-shaped, the maximum cross-sectional area of the conductor can reach 550mm<2>, the insulator is tightly packaged at the outer part of the conductor, and both sides of the insulator are provided with mutually-symmetrical grooves. A manufacturing method of the large-power single-pole winding-type seamless sliding-contact line comprises the following steps of: straightening the preliminarily-formed conductor to realize the first-time forming of the conductor; conveying the conductor and the insulator into a co-extruding mould along with a conveying track to form the co-extruded compounding of the conductor and the insulator to realize the second-time forming; and then winding a preliminarily-formed sliding-contact line through professional equipment, and punching labels and length to form the final sliding-contact line, wherein the maximum winding length can reach 5000 meters / coil. The large-power single-pole winding-type seamless sliding-contact line has the beneficial effects that: the single-pole type sliding-contact line has the characteristic that a slot of a slot-depth current collector is not easy to jump, the power can reach 100-2000A to form multiple specifications, the I-shaped structure is easy to bend and wind, the maximum length can reach 5000 meters / coil, and no seam is realized in the true sense.

Description

technical field [0001] The invention relates to a high-power single-pole winding seamless sliding contact wire and a manufacturing method thereof. Background technique [0002] The trolley line is a device to ensure that the mobile equipment maintains conductive contact during the movement. It is mainly used in various lifting and transportation machinery. The power of domestic cranes is generally too large. For the same 10T crane, the current produced by foreign countries only needs no more than 50AMP, while the domestically produced cranes need at least 80AMP. In addition, there is a huge demand for domestic heavy machinery. At present, only The traditional single-pole trolley line is used, so the failure rate is relatively high. The most prone to failure of the trolley line is the joint position, especially the high-power trolley line. Although there are rewinding seamless sliding contact lines on the market, the power is relatively small, and the sliding contact lines a...

The power of domestic cranes is generally too large. For the same 10T crane, the current produced by foreign countries only needs no more than 50AMP, while the domestically produced cranes need at least 80AMP. In addition, there is a huge demand for domestic heavy machinery. At present, only The traditional single-pole trolley line is used, so the failure rate is relatively high. The most prone to failure of the trolley line is the joint position, especially the high-power trolley line

Although there are rewinding seamless sliding contact lines on the market, the power is relatively small, and the sliding contact lines are multi-pole juxtaposed. Due to the reason of winding, the notch of the sliding contact line is relatively shallow, and it is easy to cause the collector to jump. failure, and only a single copper busbar type

In the international market, although there are single-pole seamless sliding contact lines, there are also shortcomings: the power is too small, only 300A

High power necessarily requires a sufficiently large cross-section of the conductive aluminum or copper row, but with traditional processing technology, once the conductive aluminum or copper cross-section is slightly larger, its hardness will inevitably increase, and it will be difficult to achieve winding, even if the winding is carried out. , on-site installation can not be effectively straightened
