Extra-large type geotechnical centrifuge loading separable design

Abstract

The invention discloses an extra-large type geotechnical centrifuge loading separable design. The extra-large type geotechnical centrifuge loading separable design adopts two engine bases; a high-speed bearing is adopted by the small engine base to meet the demands of high rotation speed and a big g value; and a low-speed heavy loading bearing is adopted by the big engine base to meet the demands of low speed and heavy loading, so that the separation of high speed and heavy loading is realized. Two rotating arms are mounted on a main shaft system of the same driving motor; and the two rotating arms are linked with each other through a hydraulic pressure linking device, so that time-sharing work or simultaneous work of the two rotating arms is realized. Instrument cabins are mounted on main shafts and each instrument cabin is not in contact with each rotating arm; break-make and supply of fluid, signals and a power source are achieved just through pipe connectors and cable connectors; and connecting or disconnecting is guaranteed according to the experiment need, so that separation and fastening of each rotating arm relative to the main shafts are realized. One driving motor is adopted, under the working conditions of full loading of the big rotating arm in low speed and heavy loading and full loading of the small rotating arm in high speed and light loading, motor power needed by the big rotating arm and the small rotating arm is consistent, ability of the motor is brought into full play, the maximum power of the motor is reduced, and developing and using cost is reduced.

Description

technical field [0001] The invention belongs to the field of geotechnical centrifuges, and in particular relates to a super-large geotechnical centrifuge with a detachable load design. Background technique [0002] The application of geotechnical centrifuges in engineering is becoming more and more extensive. In the past 20 years, a large number of large-scale geotechnical centrifuges have been built in China for scientific research and to solve practical civil engineering problems. The load capacity of geotechnical centrifuge is getting bigger and bigger, and its overload acceleration g value is getting higher and higher, from 25g.t to 60g.t, 150g.t, 200g.t, 400g.t and 500g.t. At present, the domestic geotechnical centrifuge has the largest capacity of 600g.t, and the China Academy of Engineering Physics is developing the centrifuge equipment for Zhengzhou University. However, the capacity and acceleration g value of the centrifuge are still far from meeting the needs of p...

Problems solved by technology

According to the conditions of use, although the disassembly of the rotating arm or the hanging basket can solve the contradiction between the high speed and heavy load of the ultra-large centrifuge and meet the functional requirements of the centrifuge, for the user, dismantling the important parts of the equipment not only poses a safety risk, but also uses inconvenient
