Abstract
The invention discloses a joint bearing device for a vacuum vessel. The joint bearing device comprises derricks (2), the vacuum vessel (3), a bottom operating platform (4), guide pins (5) and a mounting base. The mounting base is fixed on the bottom operating platform in the vacuum vessel through the guide pins. Six fulcrums are arranged on the mounting base, and are connected with lifting points on the upper part of the wall of the vacuum vessel through the six diagonal derricks. A heating tape and a plurality of thermal insulation layers are wrapped outside each derrick. The bearing requirements of a product are met in a joint bearing way by utilizing the bottom operating platform and the lifting points on the upper part in the vacuum vessel when the bearing capacity of the bottom operating platform of the traditional vacuum vessel is low. The joint bearing device can work for a long time in a vacuum low-temperature environment, and is successfully applied to a vacuum thermal test.

Need a kind of destruction on the basis of original vacuum tank structure, do not increase platform bearer ability and can complete the device of product vacuum thermal test.The present invention will, by taking associating load carrier, utilize the mode of the common carrying of bottom platform and container internal upper part suspension centre to guarantee that the carrying of vacuum tank bottom bearing platform is no more than design objective, completes product vacuum thermal test.This joint bearing device can work long hours under vacuum low-temperature environment, and is successfully applied to vacuum thermal test.Adopt joint bearing device scheme not only can meet the technical requirement of vacuum thermal test, and this kind of method be easier to realize, with low cost.
Summary of the invention
In order to improve total load-bearing capacity of existing vacuum tank, improve the test capability of existing vacuum tank, cost-saving, the present invention proposes to take joint bearing device, utilizes the common mode of carrying of bottom platform and tank internal upper part suspension centre to meet the load bearing requirements of product.
To achieve these goals, technical scheme of the present invention is as follows:
Provide a kind of for the joint bearing device in vacuum tank, comprise suspension rod 2, vacuum tank 3, bottom operating platform 4, guide finger 5 and mounting seat, it is characterized in that described bottom operating platform 4 is arranged on the bottom of described vacuum tank 3, mounting seat is fixed on the operating platform of described bottom by guide finger, the outer circumference of described mounting seat is to uniform a plurality of web members, the described vacuum tank upper inside wall magnitude setting suspension centre identical with web member, a plurality of suspension rods 2 one end are connected with affiliated a plurality of web members, and the other end is connected with affiliated a plurality of suspension centres.
Wherein said suspension rod comprises power sensor 21, Compress Spring 22 and setting nut 23, described power sensor, Compress Spring and setting nut are connected in suspension rod, described power sensor by upper lower clamp in the middle layer of suspension rod for monitoring the stressed of pull bar, described power sensor is fixed as one by screw and upper lower clamp, and described setting nut is connected with Compress Spring, for regulating the pulling force of Compress Spring.
Described bottom platform adopts stainless steel manufacture.
Described suspension rod outer wrapping heating tape and adiabatic multilayer.
Described adiabatic multilayer is by being positioned at the two-sided aluminized polyester film of outermost 16um and 9 layers of thermofin form, thermofin by one deck 20d polyamide fibre silk screen below and above the two-sided aluminized mylar of one deck 6um form, under the 20d Polyamide Yarns net bottom of thermofin, be 25um Kapton.
Described suspension rod adopts stage clip to determine force mechanisms, and the design of Compress Spring adopts the large compression travel of little rigidity, guarantees that the maximum, force that each suspension centre bears does not transfinite, and the one dimension force sensor of contacting in suspension rod can Real-Time Monitoring pull bar stressing conditions.Be provided with the actual tension variations that setting nut counterbalance spring foozle causes simultaneously.The power sensor layer that mediates, and be connected by screw as integral body with upper lower clamp, be convenient to dismounting and monitoring.Heating tape and adiabatic multilayer, guarantee that elastic modulus and the rigidity of suspension rod medi-spring does not change, working properly.
By above design, the present invention has satisfactorily completed the vacuum thermal test of test products weight over the product of vacuum tank bottom platform load-bearing index, guarantees that joint bearing device (is better than 10 in low temperature (100K), vacuum
-3pa) in situation, can work long hours.
