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 ofly on the basis of not destroying original vacuum tank structure, do not increase the platform bearer ability and can accomplish the device of product vacuum thermal test.The present invention will utilize the common mode of 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, accomplishes the product vacuum thermal test through taking the associating load carrier.This associating bogey can work long hours under vacuum low-temperature environment, and is successfully applied to vacuum thermal test.Adopt associating bogey scheme not only can satisfy the technical requirement of vacuum thermal test, and this kind method is easier to realization, 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, practice thrift cost, the present invention proposes to take the associating bogey, utilizes bottom platform and the common mode of carrying of jar internal upper part suspension centre to satisfy the load bearing requirements of product.
To achieve these goals, technical scheme of the present invention is following:
A kind of associating bogey that is used in the vacuum tank is provided, comprises suspension rod 2, vacuum tank 3; Bottom operating platform 4; Guide finger 5 and mounting seat is characterized in that said bottom operating platform 4 is installed in the bottom of said vacuum tank 3, and mounting seat is fixed on the operating platform of said bottom through guide finger; The outer circumference of said mounting seat is to being uniformly distributed with a plurality of web members; Said vacuum tank upper inside wall is provided with the quantity suspension centre identical with web member, a plurality of suspension rod 2 one ends with under a plurality of web members be connected, the other end with under a plurality of suspension centres be connected.
Wherein said suspension rod comprises force transducer 21; Compression spring 22 and setting nut 23, said force transducer, compression spring and setting nut are connected in the suspension rod; Said force transducer is used to monitor the stressed of pull bar through last lower clamp in the middle layer of suspension rod; Said force transducer is one through screw with clamps up and down, and said setting nut is connected with compression spring, is used to regulate the pulling force of compression spring.
Said bottom platform adopts the stainless steel manufacturing.
Said suspension rod outerwrap heating tape and adiabatic multilayer.
Said adiabatic multilayer is by being positioned at the two-sided aluminized polyester film of outermost 16um and 9 layers of thermofin are formed; Thermofin is made up of following one deck 20d polyamide fibre silk screen and the two-sided aluminized mylar of top one deck 6um, is the 25um Kapton under the 20d Polyamide Yarns net bottom of thermofin.
Said suspension rod adopts stage clip to decide force mechanisms, and the big compression travel of little rigidity is adopted in the design of compression spring, guarantees that the maximum, force that each suspension centre bears does not transfinite, and one one dimensional force sensor of polyphone can be monitored the pull bar stressing conditions in real time in suspension rod.Be provided with the actual tension variations that setting nut counterbalance spring foozle causes simultaneously.The force transducer layer that mediates, and be connected to integral body through screw with last lower clamp, be convenient to dismounting and monitoring.Heating tape and adiabatic multilayer guarantee that the elastic modulus and the rigidity of suspension rod medi-spring does not change, and be in proper working order.
Through above design, the present invention has satisfactorily accomplished the vacuum thermal test of test products weight above the product of vacuum tank bottom platform load-bearing index, guarantees that the associating bogey (is superior to 10 in low temperature (100K), vacuum
-3Pa) can work long hours under the situation.
