Description
Technical field
The present invention relates to a kind of cable mounting structure, more particularly to a kind of city rail vehicle roof "Jumper" cable mounting structure.
Background technology
"Jumper" cable is to realize the important component being electrically connected between the city rail vehicles organized into groups more.The effect of "Jumper" cable is real
The existing transmission of vehicle main circuit power, control signal transmission, network signal transmission and circuit negative pole equipotential.Bridge circuit is located at two
The connecting portion in compartment is saved, in vehicle operation, (such as sweep is too small, impingement rate for the stress and special operation condition of auxiliary
It is excessive etc.) significant impact can be produced to the safety of bridge circuit.Long-term complex stress effect can influence the tired longevity of "Jumper" cable
Life and weatherability.And in special operation condition, such as curve circuit operation, high acceleration pattern and brake hard operating mode, "Jumper" cable can
Can be excessive due to stress and tear fracture or connector is threaded off and loosened, cause vehicle power and control signal to be interrupted, seriously
Passenger safety is threatened, so safe operation of the "Jumper" cable topology layout rationally reliably to train is extremely important.
Current domestic railcar is generally connected using chassis "Jumper" cable, because current tramcar uses articulation steering
Frame, interfere, can not be applicable with chassis "Jumper" cable.
The cross-over mode that railcar uses at present is most of for underframe end bridging.By the vehicle frame coupling box of customization,
Car lower electric wire of getting on the bus is converged in coupling box terminal block, passes through that the connector in casing end face completes power and control signal passes
It is defeated.
Underframe end cross-over mode mainly has the disadvantage that：
(1) had a great influence by vehicle gauge, easily collided with debris on track, or scratched in repair demolition；
(2) close to ground, corroded by long-term chronics such as rubble, dust and ponding, "Jumper" cable and its composition protection will
Ask higher, cost is high；
(3) surrounding steel construction environment is complicated, and turning process is easily worn with chassis smallclothes；
(4) jumper need to carry out separated time in coupling box under car, and cable trace is longer, and distribution maintenance operation is not very under car
Just, operating efficiency is low；
(5) without support among "Jumper" cable, it is short by Action of Gravity Field, cable life cycle for a long time；
(6) connector easily loosens damage, larger potential safety hazard be present for a long time by the pulling force effect from cable；
(7) coupling box and bridging line volume are larger, and it is big to take vehicle frame space.
The end cable cross-over mode typically used for low-floor tramcar is bridged from headwall, by headwall
Internal angle mount connector, by improving end wall structure and run-through channel structure, jumper installing space is reserved, "Jumper" cable is hidden
It is arranged in inside run-through channel.
Headwall bridging mainly has a disadvantage that：
(1) end wall structure will pass through special design, also coordinate the arrangement of end miscellaneous part, and workload is big；
(2) limited by vehicle spacing, the scope of application is small.
(3) run-through channel structure needs specific customization, costly, it is necessary to spare interface and wiring space, corresponding run-through channel
Available be reduced by by space；
(4) because space limitation can not arrange electric appliance box, all cables come together in headwall top, cable exposure arrangement, deposited
In potential safety hazard, the inconvenience of later stage Inspection and maintenance；
(5) "Jumper" cable is hidden in inside run-through channel, connect mill it is more difficult be found, have electric leakage hidden danger；
(6) installation operation narrow space, installation maintenance efficiency are low；
(7) high-tension cable connecting portion is located at guest room headwall, and to guest room, passenger has potential safety hazard；
(8) it is short by Action of Gravity Field, cable life cycle for a long time without support among "Jumper" cable；
(9) connector easily loosens damage, larger potential safety hazard be present for a long time by the pulling force effect from cable；
In recent years, with the variation of city rail vehicle vehicle and organizational systems, increasing city rail vehicle is using be hinged
Bogie structure, also there occurs larger change, floor underframe for vehicle can not arrange "Jumper" cable for corresponding vehicle structure.Simultaneously in the past across
Connect mode is influenceed to restrict by factors such as complex environment, vehicle gauge, gravity factor, device layout and operating spaces, causes to bridge
Cable and its accessory protection level requirements are harsh, and wiring topology path length, operating space are small, and life cycle is short, potential safety hazard is big, headwall
Specific customization is needed with run-through channel, causes equipment purchase cost and cost of labor to raise, the problems such as maintenance efficiency is low is installed.
