In the utility model, staving has adopted double-deck form, reduce liquid nitrogen and carried out the loss of interchange of heat by housing with the external world, bung is further reducing contacting of liquid nitrogen and air, abundant cooling to gear wheel shaft, reduced the demand to liquid nitrogen, all right repeated usage of heat-preserving container, has saved cost in addition.
As optimization, described feed pipe is provided with valve.After liquid nitrogen has added, valve-off, avoids liquid nitrogen and air to carry out interchange of heat.
As optimization, described bung end face is provided with the freeing pipe being communicated with deflation hole, and described exhaust outlet end is provided with block, and described freeing pipe and block are articulated and connected.After liquid nitrogen has added, this upper cap, avoids liquid nitrogen and air to carry out interchange of heat equally.
As optimization, described staving and bung are articulated and connected, and described bung end face is provided with handle.Be easy to open bung handling gear wheel shaft.
As optimization, between the described inner bag of described staving bottom and described shell, be provided with strengthening rib.Because gear wheel shaft is all heavier, strengthening rib is set and prevents that inner bag from being crushed by gear wheel shaft.
As optimization, described bung bottom surface is provided with the heat-insulation layer matching with the bung shape of staving.Prevent that liquid nitrogen from carrying out interchange of heat by bung and the external world.
As optimization, described inner bag is stainless steel inner container.Prevent that inner bag is corroded, improve service life.
As optimization, in described cavity, be filled with warm material.Further isolated outside heat is delivered to staving inside.
As optimization, described cavity is vacuum cavity.Further isolated outside heat is delivered to staving inside.
In sum, axle of the present utility model is simple in structure with liquid nitrogen cold fitting heat-preserving container, long service life, easy to operate, input cost is low, and occupied ground is little, can rapidly its inner gear wheel shaft be cooled to fitted position, guarantee the disposable assembling success of gear and axle.
Accompanying drawing explanation
In order to make object, technical scheme and the advantage of utility model clearer, below in conjunction with accompanying drawing, the utility model is described in further detail, wherein:
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1
As shown in Figure 1, the utility model axle liquid nitrogen cold fitting heat-preserving container, comprise staving and bung, described staving comprises the cavity 3 between inner bag 1, shell 2 and inner bag and shell, described bung is provided with liquid nitrogen charging hole 4 and deflation hole 5, described bung end face is provided with the feed pipe 6 being communicated with liquid nitrogen charging hole 4, and the feed end of described feed pipe 6 is provided with outside thread.When needs carry out cold charge to gear wheel shaft, open bung, gear wheel shaft is hung in staving with driving or crane, bung closes, delivery pipe on liquid nitrogen waggon is connected with feed pipe 6, movable joint on cooperation delivery pipe and the outside thread on feed pipe 6, by delivery pipe and feed pipe 6 fixations, after fixing, open the liquid nitrogen of liquid nitrogen waggon and carry switch, liquid nitrogen is inputed in staving, and simultaneously the air in staving is discharged by deflation hole 5, gear wheel shaft cooling one end after the time in staving, reach fitted position, can hang out in gear and assemble.
In this specific embodiment, described feed pipe 6 is provided with valve 11.In staving, add after a certain amount of liquid nitrogen, the delivery pipe on liquid nitrogen waggon will be separated with feed pipe 6, and the object that valve 11 is set is to prevent that liquid nitrogen charging hole 4 is exposed in the middle of air, slows down the liquid nitrogen gasification time in staving.
In this specific embodiment, described bung end face is provided with the freeing pipe 7 being communicated with deflation hole 5, and described freeing pipe 7 exit end are provided with block 8, and described freeing pipe 7 is articulated and connected with block 8.When adding liquid nitrogen in staving, deflation hole 5 remains the pressure that inner and outer barrel is identical, liquid nitrogen is added easier, after but liquid nitrogen has added, deflation hole 5 has but become a passage of interchange of heat, covers block 8, prevents that heat from entering in staving by air.
In this specific embodiment, described staving and bung are articulated and connected, and described bung end face is provided with handle.Open or the bung that closes, only need to pull handle, convenient and swift.
In this specific embodiment, between the described inner bag 1 of described staving bottom and described shell 2, be provided with strengthening rib 9.The weight ratio of gear wheel shaft is larger, when putting into staving, can will damage in the course of time causing shock at the bottom of bucket unavoidably, and strengthening rib 9 has been strengthened the intensity at the bucket end, has extended the service life of staving.
In this specific embodiment, described bung bottom surface is provided with the heat-insulation layer 10 matching with the bung shape of staving.Liquid nitrogen in staving can be also that medium absorbs heat by bung, the heat-insulation layer 10 of setting up matches with the bung shape of staving, after the bung that closes, the heat-insulation layer 10 on bung and staving form the thermal environment of a sealing, have further reduced the impact of outer bound pair liquid nitrogen.
In this specific embodiment, described inner bag 1 is stainless steel inner container.Although liquid nitrogen does not have corrosive property, but in long use procedure, particularly in the process of handling gear wheel shaft, some impurity can enter in staving, after liquid nitrogen complete gasification, these impurity will be adsorbed on barrel wall, and inner bag is caused to corrosion, corrosion-resistant steel has extremely strong corrosion stability, can extend the service life of inner bag 1.
In this specific embodiment, in described cavity 3, be filled with warm material.Warm material can be selected phenolic foam material, and this material does not shrink under low temperature environment, not embrittlement, is desirable thermal insulating material.
Embodiment 2
As the second embodiment of the present utility model, in this specific embodiment, described cavity 3 is vacuum cavity.Because air can transferring heat, although staving has adopted double-decker, reduced interchange of heat, but in actual interchange of heat, the heat by transfer of air has accounted for greatly, to vacuumizing processing in cavity 3, form vacuum cavity, reduced to a great extent the exchange of heat.
Finally explanation is, above embodiment is only unrestricted in order to technical scheme of the present invention to be described, although by with reference to the preferred embodiments of the present invention, invention has been described, but those of ordinary skill in the art is to be understood that, can to it, make various changes in the form and details, and not depart from the spirit and scope of the present invention that appended claims limits.
