[0023] For this specific embodiment, the rod support frame 102 is fixedly connected to the fixed base plate 101 and is located on the top of the fixed base plate 101. The pressure cover 103 is arranged on the top of the rod support frame 102. The rod 104 to be tested is arranged between the rod support frame 102 and the pressure cover 103. The rod to be tested is placed on the top of the rod support frame 102 and fixed by the pressure cover 103, and then the impact resistance test of the rod 104 to be tested is performed. The connection method and usage method of the rod support frame 102, the pressure cover 103 and the rod 104 to be tested are recorded in detail in the published Chinese patent CN210513976U, which is not within the scope of protection of this application and will not be repeated here.

[0024] Among them, the fixing frame 106 is fixedly connected to the fixed base plate 101 and is located on the side of the fixed base plate 101 close to the rod support frame 102. The screw 107 is rotatably connected to the fixing frame 106 and is located on the side of the fixing frame 106. The output end of the motor 108 is fixedly connected to the screw 107 and is fixedly connected to the fixing frame 106 and is located on one side of the fixing frame 106. The placement frame 109 is threadedly connected to the screw 107 and is located on the side of the screw 107. On one side, the cylinder 110 is fixedly connected to the placement rack 109 and is located at the top of the placement rack 109. The mounting shell 111 is fixedly connected to the output end of the cylinder 110 and is located on one side of the cylinder 110. The pressure wheel 112 is fixedly connected to the mounting shell 111 and is slidably connected to the bar to be detected and is located at the bottom of the mounting shell 111. The motor 108 on the fixed rack 106 is started, and the output end of the motor 108 drives the screw 107 to rotate, so that the screw The placement rack 109 on the rod 107 moves in the direction of rotation of the screw 107 and drives the cylinder 110 to move. After the placement rack 109 is moved to a suitable position, the motor 108 stops running, causing the screw 107 to stop rotating and the placement plate to stop. At this time, the cylinder 110 is started, and the output end of the cylinder 110 pushes the mounting shell 111 down, driving the pressing wheel 112 to move down, and the pressing wheel 112 presses the bar to be tested on the bar support frame 102 104 is subjected to a falling impact, and the rod 104 to be tested is removed after being bent by the falling impact, and then the force borne by the strap to be tested during bending is obtained through the pressure sensor arranged on the pressure wheel 112. The model of the pressure sensor is LFC-20-4M-H11, thereby solving the problem that the existing construction steel bar anti-impact fatigue test device drives a heavy hammer to swing up and down to hammer the steel.

At this time, the motor 108 on the fixing frame 106 is started, and the output end of the motor 108 drives the screw 107 to rotate, so that the placement frame 109 on the screw 107 moves in the direction of rotation of the screw 107, and drives the cylinder 110 to move. After moving the placement frame 109 to a suitable position, the motor 108 When the operation stops, the screw rod 107 stops rotating and the placement plate stops. At this time, the cylinder 110 is started, and the output end of the cylinder 110 pushes the mounting shell 111 down, driving the pressure wheel 112 to descend, and the pressure wheel 112 is used to impact the rod 104 to be tested on the rod support frame 102. After the rod 104 to be tested is bent by the falling impact, it is removed, and then the force that the strap to be tested bears when bending is obtained by the pressure sensor provided on the pressure wheel 112. The model of the pressure sensor is LFC-20-4M-H11, thereby solving the problem that the existing construction steel bar anti-impact fatigue test device drives the heavy hammer to swing up and down to hammer the steel.
