Specific embodiment

Embodiment 1:

A kind of cylinder socket unit, it includes bottom plate 2, and bottom plate 2 is equipped with multiple roller devices for being used to support inner cylinder 5 3；

The roller devices 3 are in tilted layout, and the roller axis of roller devices 3 is parallel with the tangent line of outer barrel 4.

In preferred scheme, the length direction of bottom plate 2 is identical as the axis direction of outer barrel 4, and the width direction of bottom plate 2 is Arc；

Traction lifting lug 1 is equipped at the both ends of bottom plate 2.By above-mentioned scheme, before fitting, barrel jacket is attached together into placement location low On the outer barrel 4 of warm container and fixed, inner cylinder 5 is placed on the idler wheel of cylinder socket unit.By 5 upper cover one end of inner cylinder It places on cylinder socket unit, other end wirerope slings inner cylinder 5, and assembly orientation is 5 upper cover of inner cylinder from outer cylinder 4 lower part of body enters.When fitting, is translated with crane and push inner cylinder 5 will be outer by the rotation of roller devices 3 into outer barrel 4 Cylinder 4 is inserted in inner cylinder 5, after inner cylinder 5 is completely into 4 inside of outer barrel is arrived, is sling admittedly at 5 upper cover of inner cylinder with suspender belt Fixed, cylinder socket unit is integrally removed the interlayer of low-temperature (low temperature) vessel by traction device connection traction lifting lug 1, to complete low-temperature (low temperature) vessel Fitting operation can be adjusted on this basis according to the specifications and models of container by the radian size and length of bottom plate 2, To realize the fitting of the container of different size.

Embodiment 2:

On the basis of embodiment 1, in preferred scheme such as Fig. 4, bottom back-up roller is additionally provided near roller devices 3 Wheel apparatus 3' is equipped with hole on a base plate 2, and the idler wheel outer wall of bottom support roller arrangement 3' passes through hole, and is raised in the bottom of bottom plate 2 Portion, so that idler wheel outer wall is contacted with the inner wall of outer barrel 4.Thus scheme, when pulling out cylinder socket unit, idler wheel and outer cylinder Body 4 and inner cylinder 5 are rolling friction, and friction is small.In this example, the rolling of roller devices 3 and bottom support roller arrangement 3' Wheel is only subtle on cross section to interlock, and occupied space is little, more ingenious.

For preferred scheme referring in Fig. 5,6, roller devices 3 and bottom support roller arrangement 3' can using roller axis inclination angle The structure of tune.

In preferred scheme, in the roller devices 3 and bottom support roller arrangement 3', the first bearing seat 31 of idler wheel Hinged with roller mount 32, roller mount 32 is fixedly connected with bottom plate 2；
