Detailed description of the invention
1-7 describes detailed description of the invention of the present utility model in detail by reference to the accompanying drawings.
A kind of overheat rigid contact network temperature compensation means, comprise left slide rail 2 and right slide rail 3, described left slide rail 2 and right slide rail 3 outer end are connected and fixed respectively by bus duct outsourcing joint 4 and two ends bus duct 1, and left slide rail 2 is identical with the top cross-section of bus duct 1 with right slide rail 3 outer end top cross-section, to ensure the reliability be connected with bus duct.All elongatedly on the medial surface of described left slide rail 2 and right slide rail 3 be shaped with slideway 13 and slide rail 14, and two slideways 13 and two slide rails about 14 are staggered, and be inserted into in side slideway 13, left slide rail 2 linked together can be relatively free to slide with right slide rail 3 by slide rail 14; Described slideway 13 is circular groove, and is embedded with wear-resisting, self-lubricating in slideway 13 and conductive axle sleeve 9; Described slide rail 14 is circular guide shaft, and the internal diameter of the external diameter of circular guide shaft and axle sleeve 9 is adaptive.
The end face of described left slide rail 2 and right slide rail 3 is all fixed with diversion rod 7 by water conservancy diversion bearing 5, diversion seat in parallel 6, and diversion rod 7 stage casing penetrates and can follow two slide rails in offside diversion seat 6 in parallel and be free to slide.One end of described diversion seat in parallel 6 is fixed on slide rail end face, and the other end has manhole 16 and is positioned on the end face of offside slide rail; Three spring touch fingers 10 are embedded with in described manhole 16; described diversion rod 7 penetrates in spring touch finger 10; all the time hold diversion rod 7 tightly by spring touch finger 10 and realize electric current-carrying continued access; described diversion rod 7 is set with collapsible protection cover 11; carry out proofing dust and protecting to diversion rod 7, it slides, current-carrying performance to avoid dust to affect.
The end face of described left slide rail 2 or right slide rail 3 is provided with scale 12.For intuitively instructing adjustment position during installation.Described left slide rail 2 and right slide rail 3 lateral surface lower end is elongated is shaped with contact wire draw-in groove 15, and contact wire draw-in groove 15 and the contact wire draw-in groove of bus duct 1 lower end that is attached thereto corresponding.The adjacent anchor section contact wire 17 be arranged on two ends bus duct 1 is connected and fixed respectively by line ball clamping plate 8 and left and right slide rail.
Wherein, left and right slide rail and line ball clamping plate all adopt aluminium alloy extruded forming process manufacture, and precision is high.Water conservancy diversion bearing, diversion seat in parallel adopt copper material or aluminium casting to process, and electroplating surfaces with tin or silver-plated, avoids producing electrochemical corrosion between copper aluminium.Diversion rod adopts the manufacture of copper material extrusion forming process.
During installation, according to installation temperature curve, after determining compensate for clearance, left and right slide rail and two ends bus duct are connected and fixed by bus duct outsourcing joint.Contact wire is fixed by the contact wire draw-in groove of line ball clamping plate and slide rail, polishing contact wire end chamfer, and smears conduction grease, after the relevant installation parameter of detection is qualified, and installation.Described bus duct outsourcing joint adopts existing patented product (ZL201320591858.0).
