Free turnover type radial shearing force baring platform apparatus

Abstract

A free turnover type radial shearing force baring platform apparatus comprises a force bearing pedestal, a lateral limiting plate and a turnover type disc, wherein the bearing pedestal serves as the pedestal of the apparatus and can be fixed to the ground through bolt joint or crimping to ensure the entire apparatus being reliably fixed, a connecting hole array is distributed in the force bearing pedestal matches with the connecting holes in the lateral limiting plate, the lateral limiting plate as a lateral limiting part is in bolt joint with the force bearing pedestal through connecting holes and is reliably fixed with the force bearing pedestal, a cylindrical limiting boss is arranged on the center of the upper end face of the lateral limiting plate and is in shaft hole cooperation with the turnover type disc to satisfy turnover of the disc and restrict lateral movement of the disc, the disc as a testpiece installation platform has a circular hole matching with the boss of the lateral limiting plate arranged in the center and is provided with an arc guiding groove, the guiding groove matches with the connecting holes of the lateral limiting plate and the force bearing pedestal, and the disc, the lateral limiting plate and the force bearing pedestal can be connected into one body by bolts in a penetration connection manner.

Description

technical field [0001] The invention relates to the technical field of specimen strength testing, in particular to a freely revolving radial shear bearing platform device. Background technique [0002] In the static strength test, some test pieces need to be loaded with radial shear force in multiple directions in sequence. Since each radial shear force radiates along the corresponding direction, the test loading equipment needs to be adjusted according to the direction of each radial shear force. Loading equipment and fixed tooling need to be reinstalled and fixed. If there are many test pieces or test loading conditions, the test loading equipment will be frequently disassembled and assembled during the test, and the workload of test installation will be very heavy, which will reduce work efficiency and also reduce Affect the test installation accuracy. [0003] In addition, for batch test pieces, the circumferential deflection angle between the test piece interface and t...
