Under the positive driving action of the motor 402, the steel When the slide 404 moves toward the bottom of the actuator 304, the fixed rod 407 fixed at the top edge of the steel slide 404 will first trigger the lever of the first travel switch 409, and the travel switch 409 sends a command to the motor 402 to stop driving and start the actuator 304. When the telescopic end of the actuator 404 extends downward, it will drive the pressing block 305 to squeeze the top of the stair specimen 406 to test its structural performance and whether the surface of the specimen 406 is damaged under the action of a specific load force.

The performance test solves the problem in the background technology that, when testing stair components, it is necessary to manually move and adjust the position of the door frame or stair components many times, resulting in a long adjustment time and affecting the testing efficiency of the stair components. By setting a longer load frame 401, under the reverse driving action of the output end of the motor 402, the tested test piece 406 is driven by the steel slide 404 and slides out of the loading station along two linear slide rails 405, so that the stair specimen 406 is completely exposed in the driving operation space, which is convenient for taking and placing the specimen 406, avoiding danger when personnel work under the actuator 304, and reducing the safety hazards of the stair component structural performance testing device.
