Abstract
Multi-cavity conduit under city rail vehicle car of the present utility model, cross section is at least divided into two cavitys, and itself and coupling box junction are provided with seal gasket.Replace wire casing with multi-cavity conduit, save and reorganize and outfit and install the manpower and time that wire casing expends, increase cable arrangements space, improve the delivered payload capability of conduit.Multi-cavity conduit is connected to each coupling box, enhances the interchangeability of conduit under car, reduces maintenance and the cost of overhaul of car load, serve certain effect to car load lightweight and energy-saving and emission-reduction.
Description
Technical field
The utility model relates to multi-cavity conduit under a kind of city rail vehicle car, belongs to city rail vehicle manufacturing technology field.
Background technology
Modern city rail vehicle mostly is power dispersion type system configuration.Under most of equipment of the trailer system of vehicle, auxiliary system and braking system are all arranged in car, under car, number of cables is large, of a great variety, so the form generally using wire casing, coupling box, single chamber conduit and flexible pipe to work in coordination on city rail vehicle Undercarriage structure carries out connecting up and separated time.
Single chamber conduit is simple, easy for installation with its structure, save space, lightweight, etc. feature obtain general application; The features such as wire casing is convenient with its wiring, struck capacity is large obtain general application.Conduit and wire casing generally use aluminum alloy materials manufacture, and single chamber conduit generally adopts electric wire pipe clamp and floor underframe for vehicle to link together, and wire casing adopts securing member to be connected with underframe at the bottom of car.Under car, wiring relies on car inserting slot, conduit and coupling box and flexible pipe to work in coordination; wearing and tearing and other mechanical risk is exempted to protect cable; adopt clustering design, adopt the method preventing laying dust, chip, ponding etc., be convenient to draining and the ventilation of cable.
Fig. 1 shows the wire casing section structure of prior art: car inserting slot is made up of the part such as upper wire casing, inserting slot, Connection Block, guide and wiring duct cover, and each several part is linked together by securing member, then by wire casing integral hoisting under floor underframe for vehicle steel construction; Upper wire casing is divided into 2 cavitys, and inserting slot is divided into 2 cavitys, separates between each chamber with aluminium sheet; Have chute outside wire casing, Connection Block is linked together by the securing member of pre-placing in chute and wire casing body, connects guide and is connected between upper and lower two Connection Blocks.There is following problem in this structure:
1. wire casing heavy, volume is large, needs many people to operate, is inconvenient to install.
2. manufacture wire casing need mould, Costco Wholesale is higher.
3. the most material of wire casing is aluminium alloy, and the welding of aluminium alloy long slab is yielding.
4. wire casing cable is fixing needs a large amount of rubber and binding band, and workload is large.
5. if upper wire casing needs to change cable, must dismantle inserting slot and upper wiring duct cover, workload is large, not easily maintenance maintenance.
The car that Fig. 2 shows prior art places an order chamber conduit section structure: under single chamber conduit is arranged on floor underframe for vehicle steel construction by pipe clamp and fastening bolt.There is following problem in this structure:
1. wiring has limitation, can only deposit the cable of high pressure (or low pressure) kind.
2. limited because depositing cable kind, in the conduit of single chamber, space availability ratio is low.
Utility model content
The purpose of this utility model overcomes the deficiency of above-mentioned prior art exactly, provides multi-cavity conduit under a kind of city rail vehicle car.
The purpose of this utility model is achieved in that multi-cavity conduit under a kind of city rail vehicle car, it is characterized in that: cross section is at least divided into two cavitys.
In order to realize the purpose of this utility model better, under described city rail vehicle car, multi-cavity conduit and coupling box junction are provided with seal gasket.
The technical solution of the utility model, replaces wire casing with multi-cavity conduit, saves and reorganizes and outfit and install the manpower and time that wire casing expends, increase cable arrangements space, improve the delivered payload capability of conduit.Multi-cavity conduit is connected to each coupling box, enhance the interchangeability of conduit under car, reduce maintenance and the cost of overhaul of car load, improve the service clearance of the equipment such as city rail vehicle trailer system, auxiliary system and braking system, certain effect is served to car load lightweight and energy-saving and emission-reduction.
Accompanying drawing explanation
Fig. 1 is the car inserting slot structural representation of prior art.
Fig. 2 is that the car of prior art places an order chamber conduit structural representation.
Fig. 3 is multi-cavity conduit structural representation under the car of the utility model embodiment.
Be labeled as in figure: 1-cable joint, 2-cable joint, 3-wire casing body, 4-wiring duct cover, 5-tie pole, 6-cable, 7-dividing plate, 8-upper connecting base, 9-connects guide, 10-lower connecting base, 11-hose coupling, 12-single pipe clamp, 13-conduit (low pressure), 14-fastening bolt, the oval pipe clamp of 15-, the oval aluminum pipe (high pressure) of 16-, 17-direct current chamber, 18-exchanges chamber, 19-direct current chamber (low pressure), 20-direct current chamber (DC1500V), 21-exchanges chamber (AC380V).
Embodiment
For making the object of the utility model embodiment, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the utility model embodiment, technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Referring to accompanying drawing 3, under the city rail vehicle car of the present embodiment, multi-cavity conduit can be divided into two-chamber, three chambeies and multi-cavity.The large I of cavity space is identical, also can be different, determines according to specific needs.Baffle for separating is had to reduce electromagnetic interference in the middle of cavity.Multi-cavity conduit is for connecting each coupling box, and there is seal gasket junction, ensures the sealing of multi-cavity conduit and coupling box.
On the basis ensureing cable distribution performance, multi-cavity conduit project organization is simple, is convenient to produce and safeguard.Multi-cavity conduit is connected between each coupling box, and coupling box can be arranged according to physical device wiring condition, flexibly, more convenient.Multi-cavity conduit is easily installed, and takes up room little, safeguards space for chassis apparatus saves, and serves certain effect to car load lightweight and energy-saving and emission-reduction.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
