The specific embodiment

Fig. 1 is the front view of the utility model railway insulation tanker embodiment; Fig. 2 is the lateral plan of Fig. 1; Fig. 3 be among Fig. 2 A-A to view; Please refer to Fig. 1-3, present embodiment provides a kind of railway insulation tanker, comprising: underframe 1 be fixedly installed at least two group bracing frames on the end face of underframe 1, and correspondence is provided with a saddle 4 on every group of bracing frame, is fixedly installed tank body 2 at least two saddles 4; Saddle 4 is fixedly connected on the underframe 1 by at least one fastener 41, and also is filled with adiabator layer 5 between the end face of saddle 4 and underframe 1.

Particularly, every group of corresponding saddle 4 of bracing frame for example, can longitudinally arrange two groups of bracing frames on the underframe 1, and accordingly, the quantity of saddle 4 also can be two; Further, every group of bracing frame can comprise two along the bracing frame 3 of horizontally set, and can lay respectively at the place, two ends of same saddle 4.

Here, the service direction of railway insulation tanker is vertically, in horizontal surface, vertically longitudinally direction be described laterally.

Each bracing frame 3 can be weldingly fixed on the end face of underframe 1, and saddle 4 is positioned on two bracing frames 3 of same group, and can be relatively fixing by modes such as welding or bolt connections.Saddle 4 can comprise curved roof 21 and the horizonal base plate 22 that is complementary with tank body 2 sides, and is fixedly installed on the web 23 between top board 21 and the base plate 22; 41 of fasteners are fixedly connected on the end face of underframe 1 after can passing base plate 22 and bracing frame 3; Like this, the bracing frame 31 that Rigidity and strength is higher can play good supporting role to saddle 4.

The railway insulation tanker that present embodiment provides, by between the end face of saddle and underframe, bracing frame being set, can improve the Joint strenght between saddle and the underframe guaranteeing the insulation effect while of heat-insulation layer to tank body, guarantee safety and stationarity in the railway insulation tanker operational process.

In the above-described embodiments, bracing frame 3 can comprise the stay bearing plate 31 and at least two risers 32 that are fixedly installed on stay bearing plate 31 bottom surfaces of level; Offer through hole on the stay bearing plate 31, riser 32 can be fixedly installed on the end face of underframe 1 by welding manner, and 41 of fasteners are fixedly connected on the end face of underframe 1 after can passing the base plate 22 of saddle 4 and the through hole on the stay bearing plate 31.
