Abstract

The utility model discloses a hollow aluminum section railway vehicle underbody suitable for underbody cable wiring, belonging to the field of the manufacturing technology of railway vehicles. In order to solve the problem that the strength of the sleeper beam is reduced since holes are punched on the sleeper beam of the existing underbody, the hollow aluminum section railway vehicle underbody suitable for underbody cable wiring is characterized in that the underbody cable passes through the aluminum section cavity along the longitudinal direction of the vehicle; when the cable passes through the underframe sleeper beam of the underbody, the sleeper beam does not need punching, the strength of the sleeper beam is guaranteed to the greatest degree, and enough space is reserved for pipeline braking, equipment mounting and the like; and meanwhile, special protection is provided for the cable, and the cable is protected from abrasion in the aluminum section cavity.

Description

At the bottom of a kind of Aluminum Hollow section bar rail vehicle that is applicable to cable distribution at the bottom of the car

Technical field

The utility model relates to guideway vehicle manufacturing technology field, is specially at the bottom of a kind of Aluminum Hollow section bar rail vehicle that is applicable to cable distribution at the bottom of the car.

Background technology

At present; Domestic rail vehicle base fabric line adopts the mode of the outer wiring of car more; As shown in Figure 1, underframe side bar 1 is positioned at the underframe both sides, cable 5 along longitudinal direction of car when car body underframe sleeper beam 3 is passed in 2 bottoms, hollow aluminium section bar floor; Must on sleeper beam, punch 4, its shortcoming is: the sleeper beam punching has reduced sleeper beam intensity; The sleeper beam perforate need be considered the sealing in hole, has increased the difficulty that sleeper beam is made; The sleeper beam perforate has taken the locus, has compressed the space of brake piping; Equipment is original just a lot of at the bottom of the car, and the cable outer words of mule carriage again will certainly take more space, is unfavorable for the layout of equipment at the bottom of the car.

Summary of the invention

The utility model technical matters to be solved is: to the deficiency of above-mentioned prior art; Provide at the bottom of a kind of Aluminum Hollow section bar rail vehicle that is applicable to cable distribution at the bottom of the car; Cable noting be used on the sleeper beam at the bottom of passing car the time punched; Pass sleeper beam to brake piping and reserve enough spaces, simultaneously because cable is positioned at die cavity, not only can slow down cable natural aging and also since cable invisible make at the bottom of the car more succinctly attractive in appearance.

In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: at the bottom of the said Aluminum Hollow section bar rail vehicle that is applicable to cable distribution at the bottom of the car; Two foundation frame side bars about comprising are located at Aluminum Hollow section bar floor and underframe sleeper beam between the two foundation frame side bars, and its constructional feature is; Cable passes from this Aluminum Hollow section bar floor at the bottom of the said car, not perforate on the said sleeper beam side bar.

Wear and tear for fear of cable and car body, cable is designed with safety method in die cavity, and as preferred version, said cable outerwrap rubber strip.

The cable outlet place at two ends, said Aluminum Hollow section bar floor is provided with edge-protected, when cable comes out in the die cavity on hollow aluminium section bar floor, is designed with the protection structure through Aluminum Hollow section bar floor openings periphery, has avoided the cable wearing and tearing.

By said structure, through at the peripheral rubber protecting sleeve parcel that uses of car bottom line cable, run in the guide in the Aluminum Hollow section bar die cavity of floor, pass the underframe sleeper beam after, from the tapping on hollow aluminium section bar floor to the car in the regulator cubicle or down under the car in the distribution box without protectors.

So, the beneficial effect of the utility model is:

1, car bottom line cable passes in the middle of the die cavity from hollow aluminium section bar floor, and cable can be bored a hole through sleeper beam the time above that, has guaranteed the intensity of sleeper beam to greatest extent, has also reserved enough spaces for facility location and brake piping at the bottom of the car simultaneously.

2, car bottom line cable is positioned at chamber, Aluminum Hollow section bar type floor, has slowed down the aging of cable, can let at the bottom of the car more succinctly attractive in appearance simultaneously.

Below in conjunction with accompanying drawing and embodiment the utility model is done further to set forth.

The specific embodiment

At the bottom of a kind of Aluminum Hollow section bar rail vehicle that is applicable to cable distribution at the bottom of the car, referring to shown in Figure 2, at the bottom of the whole car by underframe side bar 1, Aluminum Hollow section bar floor 2, underframe sleeper beam 3, rubber strip 4, cable 5, form for edge-protected 6.Wherein, underframe side bar 1 is positioned at the underframe both sides, and cable 5 bunchys are wrapped in the rubber strip 4, and the effect first of rubber strip 4 separates cable 5 and Aluminum Hollow section bar floor 2, avoids cable and the wearing and tearing of Aluminum Hollow section bar floor 2 direct contacts in the vehicle operating process; Its two be cable when an end is through the other end from the floor rubber strip 4 can play the effect of traction, help threading; Cable 5 walk with Aluminum Hollow section bar floor 2 die cavities in; After passing underframe sleeper beam 3; Come out from the tapping on hollow aluminium section bar floor 2, like Fig. 3 and shown in Figure 4, the size of perforate is according to the soft or hard degree and the bending spring decision of cable; The perforate welded has slick and sly edge-protected 6, prevents the wearing and tearing of cable in the threading process.

The content that the foregoing description is illustrated is to be understood that to these embodiment and only is used to be illustrated more clearly in the utility model; And be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
