A mobile high-temperature coupled environment multi-dimensional space self-balancing loading system

Abstract

The invention discloses a mobile high-temperature coupled environment multi-dimensional space self-balancing loading system, comprising two mobile reaction force frames capable of walking on rails, and the mobile reaction force frames include an anchor steel beam provided with a walking device , a frame body fixed on the steel beam of the foundation and a three-dimensional guide device arranged on the top of the frame body, the three-dimensional guide device is slidingly connected with the outer wall of the high-temperature self-sensing loading beam and supports it; it uses an actuator With the mobile reaction force frame, the traditional pressure is replaced by tensile force, which solves the problem of limited laboratory height to the greatest extent, and can always maintain the vertical loading of the self-sensing loading beam. The temperature sensor is equipped with an over-temperature automatic alarm unit. The sensor can realize the over-temperature automatic alarm function of the loading beam to ensure the safety of human and machine during the test.

Description

technical field [0001] The invention relates to the technical field of fire or earthquake-fire coupling, in particular to a mobile high-temperature coupling environment multi-dimensional space self-balancing loading system. Background technique [0002] At present, the research on the mechanism and prevention and control of multi-hazard coupled disasters has become a major national demand. Among them, earthquakes and fires are the most frequently occurring coupled disasters, which may lead to major accidents and disasters. At present, the low-cycle reciprocating loading test is usually used to simulate the earthquake damage and then the fire resistance test is carried out. In low-cycle reciprocating loading tests, it is common practice to place a loading beam above the specimen, with an actuator acting above the loading beam to apply a vertical force, and a horizontal force through the horizontal actuator, followed by a fire test. However, there are the following problems i...

AI Technical Summary

Problems solved by technology

However, the following problems existed during the whole test process: (1) The loading beam could not be used under the high temperature of the open flame, which brought difficulties to the next fire resistance test; (2) The horizontal and vertical forces were applied at the same time. Complicated, and it is often impossible to ensure that the vertical force is completely loaded vertically; (3) The vertical actuator is generally above the loading beam. On the one hand, this method needs to solve the problem of the actuator working under the high temperature of the open flame in the fire test; on the other hand , the clear height of the laboratory is often limited when doing full-scale tests

Therefore, the current test device is complex to operate and has many limited conditions, which cannot well meet the requirements of the earthquake-fire coupling environment.
