Description
Technical field
The present invention relates to a kind of connection structure of cable, particularly relate to a kind of pantograph platform power circuit and control circuit cable connection structure of railcar.
Background technology
At present, along with increasing of city underground project, the requirement of railcar is increased greatly, also more and more higher to the general technical performance requriements of vehicle.The current collection mode of railcar mainly contains pantograph and the 3rd rail two kinds of modes.Pantograph is the device of iron vehicle from overhead contact line collection obtaining current, and it bears the power supply of railcar all devices, and therefore coupled power circuit cable, control cables, pipeline etc. are extremely important.
Existing technical scheme, the power circuit cable of pantograph and control circuit cable enter into vehicle body by the embedded steel tube of vehicle pantograph platform riser as shown in Figure 1, adopt rubber sleeve protection, prevent cable and steel pipe from connecing mill at embedded steel tube position.Adopt in embedded steel tube end sealant to smear sealing, prevent sleet, dust into the car.At pantograph platform welding fixation clamp mount pad, for fixing pantograph cable pipeline.Adopt welded steel pipe at vehicle interior cable pipeline, same cable adopts gum sleeve protection.
Because pantograph platform is in the outside of vehicle ceiling, this scheme needs many places perforate on pantograph platform riser, and welding embedded steel tube, for the protection of pantograph cable pipeline.Not only add design difficulty, and this cable protective scheme is not easy to operate, manufacturability is poor.Through vehicle long-time running, be exposed to sunlight, rain, snow, winter, summer exchange, Rubber Parts and sealant aging, reduce the protection of cable and the sealing of vehicle ceiling.Pantograph cable pipeline permanent seat machine up and welding job amount are very large, and in later stage installation, maintenance process, the tapped bore on fixation clamp mount pad very easily damages, and cannot keep in repair, change work difficulty and work capacity all very large.
Summary of the invention
Technical matters solved by the invention overcomes the deficiencies in the prior art, provides a kind of cable to classify and arrange, concentrate cabling, simple installation, pantograph platform power circuit easy to maintenance and control circuit cable connection structure.
The technical solution used in the present invention is pantograph platform power circuit and control circuit cable connection structure, and be pantograph platform inside pantograph platform riser, outside is vehicle interior, in cable category set, and the protection of outer employing flexible pipe.Pantograph platform riser is provided with mounting hole and wire hole, at wire hole place fixed installation seal modules, on pantograph platform, cable and flexible pipe are fixed on mount pad by pipe clamp bolt and nut, mount pad point is welded on pantograph platform, at vehicle interior, cable and flexible pipe are fixed by the pipe clamping device being fixed on car body ceiling.Because the cable of pantograph power circuit and control circuit is in category set; the protection of outer employing flexible pipe; intra-locomotive is entered through seal modules; no longer need to weld embedded steel tube, and mount pad only need spot weld on pantograph platform; pipe clamp is fixed on mount pad by bolt and nut; like this, not fragile yet, change mount pad very convenient.After cable and flexible pipe enter intra-locomotive, cable and flexible pipe are fixed by the pipe clamping device being fixed on car body ceiling, also no longer need to weld embedded steel tube.
Flexible pipe is polyethylene or polypropylene material.The thick-wall hose of polyethylene or polypropylene material, can antisum Ultraviolet radiation, still has excellent mechanical properties at low temperatures, and grease proofing, acid-proof, alkali prevention, the cable of its inside can be protected for a long time.
Seal modules, according to cable and flexible pipe caliber adjustment seal bore size, is provided with packing seal between seal modules and pantograph platform riser.Can seal better, intra-locomotive and pantograph platform are kept apart.
Pipe clamping device comprises: permanent seat is fixed on car body ceiling, and permanent seat is provided with C shape chute, and C shape chute is provided with slide block, end seat dimidiation, and the two halves of slide block with end seat link together by tie bolt, and cable and hose clamp are in the circular hole of the two halves of end seat.The fixing C shape chute that adopts of pipeline permanent seat adds slide block mode, can adjust position as required.
Be provided with cable sheath in end seat, flexible pipe and cable can be protected better, reduce wear.
The invention has the beneficial effects as follows and effectively improve the fixing of pantograph cable pipeline and cable protective.Structure is simple, and volume is little, handled easily, enhances productivity.Reduce design difficulty, reduce cost of product and maintain cost in the future.The field erected mounting means of pantograph pipeline is simple to operation.
