Giant soil engineering centrifuge hanging basket

Abstract

The invention discloses a giant soil engineering centrifuge hanging basket which comprises hanging lugs, hanging arms and a platform. The hanging lugs are two in number and are mutually symmetrical, the hanging arms are two in number and are mutually symmetrical, upper hinge pin holes used for being connected with rotating arms of a centrifuge are formed in upper ends of the hanging lugs, more than one group of lower hinge pin holes used for being connected with the hanging arms are formed in the lower end of each hanging lug, upper hinge pin holes matched with the lower hinge pin holes of the hanging lugs are formed in upper ends of the hanging arms, multiple lower hinge pin holes used for being connected with the platform are formed in the lower end of each hanging arm, and shaft axes of the upper hinge pin holes and shaft axes of the lower hinge pin holes of the hanging arms are vertical to one another; the lower hinge pin holes of the hanging lugs are connected with the upper hinge pin holes of the hanging arms through upper hinge pins and knuckle bearings, and the lower hinge pin holes of the hanging arms are connected with the platform through lower hinge pins. The hanging lugs and the hanging arms are adopted to be connected with the rotating shafts and the platform, the upper hinge pin holes of the hanging lugs can be connected with a sliding bearing or a copper bush between the rotating arms, and load-bearing capacity of the hanging basket is improved; the connecting structure of the hanging lugs and the hanging arms has the advantages of large load-bearing capacity and strong expansibility.

Description

technical field [0001] The invention relates to a geotechnical centrifuge hanging basket, in particular to a giant geotechnical centrifuge hanging basket with a capacity exceeding 1000 gt. Background technique [0002] The hanging basket is the key part of the geotechnical centrifuge, and it is the link between the boom of the centrifuge and the geotechnical model. It is located in the maximum acceleration field of the centrifuge. When rotating, it bears the huge centrifugal force generated by the model, the model box and its own mass. Its own rigidity and weight directly affect the scale and operating conditions of the centrifuge. [0003] In recent years, with the continuous emergence of large-scale civil engineering, especially the construction of large-scale dams and deep ports, there is an urgent need for giant multifunctional geotechnical centrifuges to conduct centrifugal model tests to guide engineering design and construction. At present, the largest capacity geote...

AI Technical Summary

Problems solved by technology

[0007] If the existing technology is still used to design the ultra-large-scale giant geotechnical centrifuge basket structure with a large mass, the two sets of joint bearings connecting the basket and the rotating arm need to bear the weight of the entire basket and the model, and there is no such thing at home and abroad. Large size joint shaft is optional

In addition, the size of the hanging platform platform is too large. Under the high centrifugal field, the deflection of the plane on the platform is difficult to control. If the deflection is too large, it will affect the accuracy of the geotechnical test.
