A Pseudodynamic Loading System Safety Support Platform

Abstract

The invention provides a pseudo-dynamic loading system safety support platform. The platform comprises a support pallet which is used for supporting a pseudo-dynamic loading system actuator, a height adjustment device which is used for adjusting the height of the support pallet, a support frame which is used for arranging the height adjustment device, a moving device which is used for moving the support frame, and a load retracting device which is used for transmitting force transmitted from the support frame to the ground. The support pallet is connected with the height adjustment device. The height adjustment device is arranged on the support frame. The load retracting device and the moving device are arranged at the bottom of the support frame. The platform provided by the invention has the advantages of high operability, flexibility and applicability, reasonable structure and clear force transmission path. The security of the pseudo-dynamic loading system is enhanced.

Description

technical field [0001] The invention relates to the field of safety equipment, in particular to a safety support platform for a pseudo-dynamic loading system. Background technique [0002] Pseudo-dynamic loading system is a large-scale instrument and equipment serving civil structural tests. The core of the pseudo-dynamic loading system is the actuator, which is fixedly installed on the reaction wall through the base and the suspension cable at the front end. During the experiment, the actuating head of the actuator extends and contracts back and forth at a set frequency to provide simulated power; at this time, with the extension and contraction of the actuating head, the front end of the actuator and the reaction wall The attached stay cables that hold the actuator are also stressed. According to the characteristics of the dynamic test, the completion of a test often requires the actuator to extend and contract back and forth at multiple set frequencies to provide suffici...

AI Technical Summary

Problems solved by technology

According to the characteristics of the dynamic test, the completion of a test often requires the actuator to extend and contract back and forth at multiple set frequencies to provide sufficient simulated power, which makes the suspension cable at the front end of the actuator occur. Possibility of fatigue damage; therefore, a potential safety hazard

If the suspension cable is damaged, it will cause the actuator to lose stability and fall. Since the actuator is heavy, once it falls, it will cause a safety accident.
