Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] A precast component strength testing device, such as Figures 1-5 As shown, the device includes a support frame 1 and a test cylinder 2 fixedly connected to the support frame 1. Guide rods 3 are fixedly connected to both sides inside the support frame 1, and support rods 4 are fixedly connected to the guide rods 3. A placement plate 5 is slidably connected to the guide rods 3, and a handle 6 is fixedly connected to the placement plate 5. A baffle 7 is slidably connected to the support frame 1. The support frame 1 is equipped with a lifting assembly for lifting the baffle 7. When testing the precast component, the precast component is first moved and placed in the center of the placement plate 5. Then, the handle 6 is grasped and the placement plate 5 is pushed so that the placement plate 5 is inside the support frame 1 and the precast component is under the test cylinder 2. Then, the test cylinder 2 is activated to extend, and the extension end of the test cylinder 2 will trigger the lifting assembly. Once the lifting component no longer obstructs the baffle 7, the baffle 7 will fall due to gravity, sealing the opening on the side of the support frame 1 near the support rod 4. Then, the test cylinder 2 will contact the precast component and apply pressure to test its strength. If the precast component is damaged and fragments fly out, they will be blocked by the baffle 7 and the support frame 1, preventing injury. When the test is completed, the test cylinder 2 is activated to retract and reset. When the test cylinder 2 is fully reset, the lifting component will also reset, lifting the baffle 7. At this point, the handle 6 can be grasped to pull out the placement plate 5 to check the damage to the precast component. This avoids the situation where the baffle 7 fails to fall during the test, thereby reducing safety hazards.

[0024] like Figures 2-4 As shown, the lifting assembly includes a slider 8 that is slidably connected to both sides inside the support frame 1 and a wedge block 9 that is fixedly connected to the slider 8. The wedge block 9 is in contact with the baffle 7. The support frame 1 is provided with a driving component for driving the wedge block 9 to slide. The driving component includes a spring telescopic rod 10 fixedly connected to the support frame 1, an inclined block 11 fixedly connected to the telescopic end of the spring telescopic rod 10, and connecting rods 12 fixedly connected to both sides of the inclined block 11. The two connecting rods 12 are fixedly connected to the adjacent wedge blocks 9 respectively. The inclined block 11 is in contact with the telescopic end of the test cylinder 2.

[0025] like Figures 2-4 As shown, when the test cylinder 2 extends, the telescopic end of the test cylinder 2 will push against the inclined block 11, causing the inclined block 11 to move away from the support rod 4. At this time, the inclined block 11 will simultaneously drive the wedge block 9 away from the support rod 4 via the connecting rod 12. The spring telescopic rod 10 will also be pushed and deformed into a contracted state by the inclined block 11. When the wedge block 9 moves away from the support rod 4, the wedge block 9 will no longer be in contact with the baffle 7. At this time, the baffle 7 will fall down due to gravity for protection. Then the test cylinder 2 continues to extend, and the inclined block 11 will... The spring telescopic rod 10 is always in contact with the outer wall of the telescopic end of the test cylinder 2. When the test is completed, the test cylinder 2 will retract. When the test cylinder 2 is fully retracted and reset, the spring telescopic rod 10 will reset, driving the inclined block 11 to reset. At this time, the inclined block 11 will also drive the wedge block 9 to reset and move towards the support rod 4 through the connecting rod 12. Then the wedge block 9 will push the bent part of the baffle 7, so that the baffle 7 slides upward on the inclined surface of the wedge block 9, thereby lifting the baffle 7. Then the placement plate 5 can be pulled out.

[0026] like Figures 2-4 As shown, an electric push rod 13 is fixedly connected to the support frame 1. A limit block 14 is fixedly connected to the output end of the electric push rod 13. When the test is completed and the placement plate 5 is pulled out, the handle 6 can be placed on the upper side of the limit block 14. Then, the electric push rod 13 is activated. The electric push rod 13 will drive the limit block 14 to contact the handle 6. Then, the side of the placement plate 5 that is close to the handle 6 will be lifted by the limit block 14, causing the placement plate 5 to tilt. At this time, the precast fragments that fall on the placement plate 5 will slide off the placement plate 5.

[0027] like Figure 5 As shown, the placement plate 5 has several insertion slots 15, and a stop block 16 is detachably connected in the insertion slot 15. When the precast part is placed on the placement plate 5, the stop block 16 can be installed in the corresponding insertion slot 15 first, and then the precast part is placed, so that the precast part fits with the stop block 16. Then the stop block 16 can prevent the precast part from sliding when the placement plate 5 is tilted.

[0028] like Figure 4 As shown, several rollers 17 are rotatably connected to the bottom side of the placement plate 5. The rollers 17 have elastic deformation capability. A support rod 18 is fixedly connected to the support frame 1. The other end of the support rod 18 is fixedly connected to the adjacent support rod 4. The rollers 17 make it easier to pull and push the placement plate 5. When the test cylinder 2 contacts the preform, the pushing pressure will be transmitted to the rollers 17. At this time, the rollers 17 will deform while maintaining contact with the support rod 18. After the rollers 17 deform, the placement plate 5 will contact the inner bottom side of the guide rod 3. At this time, the preform test can be carried out normally without any force leakage.

[0029] like Figures 1-4 As shown, the support frame 1 is rotatably connected to the baffle 7 on both sides. Both contact rollers 19 are in contact with the baffle 7. The contact rollers 19 can make the baffle 7 slide more smoothly and prevent the baffle 7 from getting stuck when the wedge block 9 is lifted.

[0030] like Figures 2-4 As shown, a receiving box 20 is detachably connected to the support frame 1. When the precast component is crushed by the test cylinder 2, it is used to collect the fragments of the precast component so that the receiving box 20 can be pulled out directly when it is necessary to clean up the fragments of the precast component.

[0031] Working principle: When testing the precast component, first move the precast component to the center of the placement plate 5, then grasp the handle 6 to push the placement plate 5 so that the placement plate 5 is inside the support frame 1 and the precast component is under the test cylinder 2. Then, start the test cylinder 2 to extend. Subsequently, the extension end of the test cylinder 2 will push the inclined block 11, causing the inclined block 11 to move away from the support rod 4. At this time, the inclined block 11 will simultaneously drive the wedge block 9 away from the support rod 4 through the connecting rod 12. The spring extension rod 10 will also be pushed by the inclined block 11 and deform into a contracted state. When the wedge block 9 moves away from the support rod 4, the wedge block 9 will no longer be in contact with the baffle 7. The baffle 7 will fall due to gravity and block the opening of the support frame 1 near the support rod 4. Then the test cylinder 2 will contact the precast component and apply pressure to the precast component to test its strength. At this time, if the precast component is damaged and flying fragments are blocked by the baffle 7 and the support frame 1, they will not cause injury.

[0032] When the test is completed, the test cylinder 2 retracts and resets. When the test cylinder 2 is fully reset, the spring telescopic rod 10 resets, driving the inclined block 11 to reset as well. At this time, the inclined block 11 also drives the wedge block 9 to reset and move towards the support rod 4 via the connecting rod 12. Then, the wedge block 9 pushes against the bent part of the baffle 7, causing the baffle 7 to slide upward on the inclined surface of the wedge block 9, thereby lifting the baffle 7. Then, grasp the handle 6 to pull out the placement plate 5, so that the handle 6 is above the limit block 14. When the electric push rod 13 is activated, it will cause the limiting block 14 to contact the handle 6. Then, the side of the placement plate 5 closest to the handle 6 will be lifted by the limiting block 14, causing the placement plate 5 to tilt. At this time, the precast fragments falling on the placement plate 5 will slide off the placement plate 5 and fall into the receiving box 20. Then, when the electric push rod 13 is activated to retract and reset, the placement plate 5 can be pulled out to check the damage to the precast parts. This can prevent the baffle 7 from not falling during the test, thereby reducing safety hazards.

All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
