The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
Middle level underframe in the double-deck special vehicle of using when the utility model provides a kind of train carrier, as Fig. 1～shown in Figure 2, this middle level underframe mainly comprises two movable underframe 1 and a fixed frame 2, two movable underframe 1 lay respectively at the both sides of fixed frame 2, are undertaken hinged by turning joint 3 between them.Fixed frame 2 is fixed on the train body.
As Fig. 3～shown in Figure 5, movable underframe 1 comprises basic framework 11, floor 12, and such as playing a Hanging roller 13, go up cab apron mount pad 14, going up annexes such as cab apron folding axle bed 15.Basic framework 11 constitutes frame by two end carriages 16 and two curb girders 17, some crossbeams 18 of overlap joint and suitable beam 19 in frame.End carriage 16, curb girder 17, crossbeam 18 and become basic framework 11 along beam 19 assembly weldings.On an end carriage 16 in basic framework 11 outsides, promptly away from an end of fixed frame 2, Hanging roller 13 has been installed, gone up cab apron mount pad 14, gone up cab apron folding axle bed 15 etc.At the end of basic framework 11, with the fixed frame 2 common two or more turning joints 3 of corresponding installation near fixed frame 2.Be equipped with floor 12 on basic framework 11, basic framework 11 is consistent with floor 12 shapes, as shown in Figure 6, arch, open and flat shape all around in the middle of being, this shape is that the roof profile according to roadlice carries out design-calculated.Floor 12 upper surfaces have anti-skidding line.
Shown in Fig. 7～9, fixed frame 2 also mainly is by end carriage 21, curb girder 22, crossbeam 23, becomes basic framework along beam 24 assembly weldings, and laying floor 25 on the skeleton, at two crossbeam ends of skeleton engagement plate 26 is installed, be connected mutually with the movable underframe of both sides, keep a plane.
In the foregoing description,, between curb girder 17, crossbeam 18, and between the curb girder 22, crossbeam 23, all can weld gusset 4, with the tightness of additional strengthening as Fig. 4 and shown in Figure 8.
Shown in Figure 10～11, turning joint 3 mainly is made up of first axle bed 31, second axle bed 32, rotating shaft 33, axle bumper 34 and lining 35.During assembling, with first axle bed, 31 assembly weldings to movable underframe 1, with second axle bed, 32 assembly weldings on fixed frame 2, first axle bed 31 has the crotch mouth, second axle bed 32 has tenon, and both articulate by wearing rotating shaft 33, realizes movable underframe 1 and fixed frame 2 purpose of connecting with this.
