[0022] See also Figures 1 to 5 As shown, a strength testing device for plates of civil air defense projects comprises a base 1, on which two vertical arms 2 are arranged, and a flat support platform 3 is arranged above the base 1, the flat support platform 3 is connected to the base 1 through the vertical arms 2, the flat support platform 3 is parallel to the base 1, and a push plate 4 is also arranged above the base 1, the push plate 4 is parallel to the base 1, and the push plate 4 is located between the flat support platform 3 and the base 1, a moving component 5 is arranged on the surface of the push plate 4 close to the flat support platform 3, so that the push plate 4 moves vertically, and a stamping block 6 is connected to the other end face of the push plate 4, and the stamping block 6 and the push plate 4 move vertically at the same time; a bearing platform 7 is hinged on each vertical arm 2, and the bearing platform 7 is located between the base 1 and the push plate 4, and the two bearing platforms 7 are symmetrically arranged, and the protective material to be tested is placed on the bearing platform 7, the moving component 5 controls the push plate 4 to move downward, and the stamping block 6 stamps the protective material, so as to detect whether the strength of the protective material meets the standard.

[0023] In order for the punching block 6 to punch the protective material, the motion component 5 includes a hydraulic cylinder 8, a telescopic rod 9 is connected to the hydraulic cylinder 8, the other end of the telescopic rod 9 is fixed to the push plate 4, and two limit rods 10 are also installed on the push plate 4. The length direction of the limit rod 10 is parallel to the length direction of the telescopic rod 9, and the limit rod 10 is set with the central axis of the telescopic rod 9 as the symmetry axis. The setting of the limit rod 10 can make the telescopic movement of the telescopic rod 9 more stable. A limit block 11 is fixedly connected to the other end of the limit rod 10, and a through hole 12 matching the limit rod 10 and the telescopic rod 9 is set on the flat support platform 3. The hydraulic cylinder 8 and the limit block 11 are located above the flat support platform 3. The hydraulic cylinder 8 controls the telescopic movement of the telescopic rod 9, and the limit block 11 limits the maximum displacement of the telescopic rod 9;

[0024] Slide blocks 13 are fixed at both ends of the push plate 4, and a limiting groove 14 matching the slide block 13 is arranged on the vertical arm 2. The limiting groove 14 passes through the vertical arm 2. The limiting groove 14 is arranged along the length direction of the vertical arm 2. The slide block 13 slides vertically in the limiting groove 14, so that the push plate 4 moves along the length direction of the vertical arm 2, and the stability of the movement of the push plate 4 is ensured.

[0025] In order to place the protective material on the carrier platform 7 for inspection, there are two carrier platforms 7, and a conveyor belt 15 is also arranged on the base 1. The conveyor belt 15 is located between the two carrier platforms 7. The upper surface of the conveyor belt 15 is on the same plane as the upper surface of the carrier platform 7 in a horizontal state. The length of the protective material is greater than the width of the conveyor belt 15 and less than the distance between the two vertical arms 2. The protective material can be placed on the conveyor belt 15. The conveyor belt 15 moves to transport the protective material to the top of the carrier platform 7. A support seat 16 is arranged below the carrier platform 7. The support seat 16 is fixed on the vertical arm 2. The support seat 16 supports the carrier platform 7 to prevent the protective material from being punched. When the load-bearing platform 7 is turned down, and the load-bearing platform 7 is in a horizontal state without the action of other external forces, the load-bearing platform 7 is set with the central axis of the telescopic rod 9 as the symmetry axis, the outer end of the load-bearing platform 7 is passed through the limit groove 14, and the load-bearing platform 7 is hinged with the vertical arm 2. When both ends of the protective material are on the load-bearing platform 7, the inner end of the load-bearing platform 7 is turned upward, the protective material is lifted up, and the protective material is moved vertically away from the conveyor belt 15, so that the protective material is located on the load-bearing platform 7. When the punching block 6 moves downward, there is no supporting force at the position where the protective material contacts the punching block 6, and the hydraulic cylinder 8 punches toward the protective material through the punching block 6, thereby completing the detection of the strength of the protective material.

[0026] Due to the flipping of the carrying platform 7, the carrying platform 7 can lift the protective material so that the protective material no longer moves with the conveyor belt 15. In order to realize the flipping of the carrying platform 7, the cross-section of the carrying platform 7 is trapezoidal, and an L-shaped rod 17 is connected to the push plate 4. The L-shaped rod 17 is connected to the push plate 4 through the slider 13. The L-shaped rod 17 includes a straight rod 18. The length direction of the straight rod 18 is parallel to the length direction of the vertical arm 2. The straight rod 18 extends in the direction close to the carrying platform 7. When both ends of the protective material are on the carrying platform 7, the hydraulic cylinder 8 is started, and the telescopic rod 9 causes the stamping block 6 to move downward, thereby driving the straight rod 18 to move downward. When the straight rod 18 applies downward pressure to the outer end of the carrying platform 7, the outer end of the carrying platform 7 flips downward, and at the same time, the inner end of the carrying platform 7 flips upward, lifting the protective material so that it no longer moves with the conveyor belt 15. Since the cross-section of the carrying platform 7 is trapezoidal, and when the carrying platform 7 lifts the protective material, the contact between the protective material and the carrying platform 7 is surface contact, and the protective material has a certain stability at this time.

[0027] During implementation, the conveyor belt 15 is started, and protective materials are intermittently placed on the conveyor belt 15. When the two ends of the protective material are respectively on the two bearing platforms 7, the hydraulic cylinder 8 is started to extend the telescopic rod 9, driving the punching block 6 to move downward. At this time, the straight rod 18 moves downward until the straight rod 18 puts pressure on the bearing platform 7. Due to the continuous downward movement of the straight rod 18, the bearing platform 7 flips over, the protective material is lifted up, and the protective material no longer moves with the conveyor belt 15. When the protective material contacts the bearing platform 7 surface, the protective material is stably placed on the bearing platform 7, and the protective material is in a horizontal state at this time. The downward movement of the punching block 6 produces a certain amount of stamping on the protective material, that is, the strength test of the protective material is completed. At this time, the telescopic rod 9 drives the punching block 6 to move upward, and the bearing platform 7 flips to a horizontal state due to gravity. If the protective material is unqualified, it falls on the synchronous belt. If the protective material is qualified, the center position of the protective material contacts the conveyor belt 15, so that it moves with the conveyor belt 15. If the strength of the remaining protective materials needs to be tested, the above steps can be repeated.
