Description
Technical field
The utility model relates to a kind of trolley be arranged on light rail.
Background technology
Light rail trolley is widely used in the Power supply of large-scale metallurgical bridge crane, and trolley is the equipment for powering to crane or crane.Due to can larger vibration force be produced in the process that crane or crane run on light rail, cause the poor electric conductivity of light rail and voltage loss large, so, in the prior art, generally adopt the mode of laying aluminium row side by side to power for the current-collector on crane or crane.Aluminium row is wherein arranged on the side of light rail usually, and pressing plate is provided with and compensating cable carries out capacity compensation to light rail trolley on aluminium row, but because the change of temperature can cause expanding with heat and contract with cold of trolley rail joint place, so, this kind of trolley not only have complex structure, it is large to take up room, poorly conductive, annex and tie point are more and install the problems such as inconvenience, but also have the shortcomings such as the large and failure rate of current compensation ability, maintenance is very high; Due to aluminium row current breaking compensation light rail conductive, it is easily vibrated causes bolt looseness, so its electric energy loss is comparatively large, it is unreliable to cause running; In addition, aluminium row is subject to oxide etch, and it is not suitable for using in the adverse circumstances such as high temperature, high dust, high corrosion.
Disclosed in No. 201608416U, Chinese patent, name is called that " Special joint for trolley line " provides a kind of scheme.This kind of joint comprises copper bar and be provided with piecing devices on copper bar, and piecing devices wherein comprise joint protective cover, is provided with connects cover in joint protective cover inside, and the sidewall connecting cover is provided with inspection hole, and the inside connecting cover is provided with elastic contact chip.The problem such as although this joint can solve installation and maintenance complex procedures and insulation property are poor, it is not suitable for using in adverse circumstances and reducing electric energy loss amount, and the problem such as reliability service.
Name disclosed in No. 201307703Y, Chinese patent is called that " a kind of trolley " adopts copper electric conductor and type steel support seat, and wherein copper electric conductor is the cavity body of lower ending opening, and type steel support seat shaped upper part and cavity body shape match.Although copper electric conductor is coated on two sides of type steel support seat to downward-extension, its electric conductivity can be improved and increase ampacity, but the copper electric conductor in this trolley is not arranged on light rail, so, this trolley do not solve complex structure, take up room large, poorly conductive, failure rate are very high, electric energy loss is larger, reliable, annex and tie point is more and install the problems such as inconvenience, and cost of manufacture is higher.
Summary of the invention
Task of the present utility model is to provide a kind of utilization and directly solves poor electric conductivity with the mode contacted and the trolley be arranged on light rail of the problem such as voltage loss is large.
What the utility model proposed the trolley be arranged on light rail is made up of the copper bar and temperature compensation component being arranged on light rail web of the rail both sides, described temperature compensation component comprises the drainage plate being arranged on two light rail butt seam positions and being fixed on the connecting plate on copper bar and being arranged on bottom the light rail of connecting plate both sides, and the corrective component be arranged on below connecting plate on two light rails, be connected with transition cable between described two pieces of drainage plates.
Described corrective component comprises the flat part be arranged on bottom two docking light rails, and this flat part is connected by welded type with a light rail end region, and utilizes with another light rail end region and bend the mode that plate extrudes and be connected.
Every side of described light rail end is provided with the bending plate that two interblocks are separated with certain distance.
Described copper bar is fixed in light rail web of the rail both sides by bolt.
The copper bar that the trolley that what the utility model proposed be arranged on light rail adopts is fixed on light rail, causes its structure very simple, and can reduce the workload of installation, modification maintenance and repair; Simultaneously the end of copper bar is provided with temperature compensation component, this temperature compensation component is provided with connecting plate and drainage plate, and corrective component, and it can synchroballistic light rail conductive, can increase substantially electric conductivity and reduce electric energy loss amount, and failure rate is very low; In addition, corrective component is made up of parallel-plate and bending plate, makes the joint of two light rail contacts site closely reliable, is very suitable for using this kind of trolley in the adverse circumstances such as high temperature, high dust, high corrosion.
Accompanying drawing explanation
Accompanying drawing 1 is the surface structure schematic diagram of a kind of trolley embodiment be arranged on light rail that the utility model proposes;
Accompanying drawing 2 is end views of Fig. 1;
Accompanying drawing 3 is vertical views of Fig. 2.
Embodiment
See Fig. 1 to Fig. 3, these three figure give the surface structure schematic diagram being arranged on the trolley embodiment on light rail that the utility model proposes.This trolley comprises copper bar 1 and temperature compensation component, and wherein, copper bar 1 is the both sides being arranged on light rail 2 web of the rail by bolt 3, and the length of copper bar 1 is substantially equal with the length of a light rail 2.Temperature compensation component comprises connecting plate 4, drainage plate 5, transition cable 6 and corrective component 7.Due to each light rail 2 being all provided with copper bar 1, causing between adjacent two copper bars 1 and have gap, so be provided with connecting plate 4 having between two of position, gap copper bars 1, connecting plate 4 is fixed on copper bar 1 by bolt 3, drainage plate 5 is arranged on the bottom of the light rail 2 below connecting plate 4, and light rail 2 one sides are respectively arranged with the drainage plate 5 that two interblocks are separated with certain distance, and are connected with three transition cables 6 between two pieces of drainage plates 5, corrective component 7 comprises one flat plate part 71, this flat part 71 is arranged on the bottom of two light rail 2 docking sites, and the middle part of flat part 71 is arranged on two light rail 2 butt seam 8 positions, this flat part 71 is connected by the mode of welding with the end regions of a light rail 2, namely weld part 73 is provided with between flat part 71 and light rail 2, and flat part 71 and another light rail 2 end regions utilize and bend the mode that plate 72 extrudes and be connected, described bending plate 72 is provided with four pieces, the bending plate 72 that two interblocks are separated with certain distance is provided with in every side of light rail 2 end, namely the position that bending plate 72 contacts with flat part 71 is welded in flat part 71, be provided with weld part 74 between the two, the position that bending plate 72 contacts with light rail 2 is welded on light rail 2.Because corrective component 7 is fixed in same flat part 71 by two docking light rails 2, and two light rails 2 are fixed by the mode welding and bend plate 72 extruding by flat part 71, so, the longitudinal breathing of freedom that this kind of rectification can realize light rail 2, strictly limit again light rail 2 simultaneously and be out of shape dislocation, and this apparatus for correcting structure is simple, use cost is low, and successful, the even running of trolley can be ensured.
