The underframe of coach stage casing used at present typically using beam welding inside and outside slab groove-shaped longitudinal beam and flute profile or is riveted
To turn into a steelframe, by welding or bolt connection and body platform, left and right gusset and front and rear connection is enclosed.It exists as follows
Defect：One is due to that Undercarriage structure integral rigidity is big, it is impossible to effective to absorb the vibration that ground and engine are transmitted to, shadow
NVH (Noise noises, Vibration vibrations and Harshness sound vibration roughness) performance of car is rung, is especially being collided
When, it is impossible to collision energy is effectively absorbed, passive safety is poor；Two be to take car bottom space greatly, and passenger deposits one's luggage
It is limited, especially big part, it is difficult to put in and deposited；Three be to lack general between pipeline difficult arrangement, different length vehicle
Property, cause internal mixed and disorderly, the attractive in appearance and actual use of influence.
The content of the invention
In order to solve above-mentioned technical problem, it is an object of the invention to provide a kind of underframe of coach stage casing supporting mechanism,
By design triangle frame and penetration pipe in first support bar, the problem of car bottom is connected up is solved, also passes through the second rectangle
The dynamic assembling second support bar of upper slide of frame, solves the problem of passenger's heavy luggage is deposited.
The purpose of the present invention can be achieved through the following technical solutions：
A kind of underframe of coach stage casing supporting mechanism, including the first rectangle frame and the second rectangle frame be arrangeding in parallel, described
One rectangle frame and the second rectangle frame are placed vertically, and two are welded between the first rectangle frame and the second rectangle frame upper end both sides
Crossbeam, equally distributed bottom girder is welded between the first rectangle frame and the second rectangle frame lower end；
Equally distributed first support bar, first support bar are vertically welded between the first rectangle frame upper and lower ends
On be vertically and fixedly provided with tripod, tripod upper end is fixed with two interconnection penetration pipes；
Equally distributed second support bar is provided with the middle of second rectangle frame, second support bar upper and lower ends are provided with convex
Platform, the second rectangle frame upper and lower ends are provided with the chute matched with boss；
Fixed plate is provided between described two crossbeams.
Further, second rectangle frame coordinates with second support bar for dovetail.
Further, the surface area of the fixed plate is more than the surface area of crossbeam.
Further, it is fixedly linked between described two bottom girders by connecting rod.
Further, it is fixedly linked between the bottom girder and fixed plate by right angle frame.
Beneficial effects of the present invention：
1st, the present invention is used to support underframe of coach stage casing position, with fixation, is unlikely to deform feature, reduces car
What is produced in the process of moving rocks, very useful, with promotional value.
2nd, by design triangle frame and penetration pipe in first support bar, the work of car bottom wiring, cabling are simplified
It is clearly clear, make to keep clean and tidy in underframe of coach, reduce circuit floor space.
3rd, by slidable fit second support bar on the second rectangle frame, passenger's heavy luggage can be stored in underframe
Portion, without being positioned over roof, safety coefficient is high.
4th, by being welded and fixed plate on crossbeam, the lifting surface area of bed board in increase car, it is to avoid bed board because of stress not
Cause rough phenomenon to occur, increase the service life, economic value is high.
