Description

Technical Field

[0001] This utility model relates to the field of precast component testing technology, and in particular to a testing device for precast concrete components. Background Technology

[0002] Concrete precast component testing equipment is specialized equipment used to inspect the quality of precast concrete components. It primarily targets precast slabs, beams, columns, walls, and other prefabricated building components. Testing includes key indicators such as dimensional deviations, appearance defects (cracks, honeycombing, etc.), strength (compressive and flexural strength), rebar location, and protective layer thickness. Common equipment includes rebound hammers, ultrasonic testing machines, rebar scanners, and compression testing machines.

[0051] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of a testing device for precast concrete components.

[0052] A testing device for precast concrete components includes a base 1 and multiple support legs 2. It also includes a fixing mechanism mounted on the base 1 for fixing the precast component; and a testing mechanism mounted on the base 1 for strength testing of the precast component. The testing mechanism includes: a lifting device mounted on the base 1 for lifting operations; a mounting component 3 mounted on the lifting device for component installation; a drive motor 4 mounted within and fixedly connected to the mounting component 3; a rotating component 5 mounted at and fixedly connected to the output end of the drive motor 4; and multiple movable racks 6 mounted within and slidably connected to the mounting component 3.

[0053] refer to Figure 1 and Figure 2 In a preferred embodiment, the lifting device includes multiple support columns 7, which are disposed on the base 1 and fixedly connected to the base 1; a fixing plate 8, which is disposed on the support columns 7 and fixedly connected to the support columns 7; a hydraulic cylinder 9, which is disposed inside the fixing plate 8 and fixedly connected to the fixing plate 8; and a fixing block 10, which is disposed on the fixing plate 8 and fixedly connected to the fixing plate 8.

[0054] refer to Figure 4 and Figure 5 In a preferred embodiment, the testing mechanism further includes: a mounting section having multiple mounting sections disposed within the mounting member 3 for component mounting; and a testing section having multiple testing sections disposed within the mounting sections for testing operations.

[0055] refer to Figure 4 In a preferred embodiment, the mounting part includes: a mounting block 11, disposed on the movable rack 6 and fixedly connected to the movable rack 6; an anti-collision groove 12, disposed on the mounting block 11, for preventing the mounting block 11 from colliding with the movable rack 6; and a mounting shell 13, disposed on the mounting block 11 and fixedly connected to the mounting block 11.

[0056] refer to Figure 4 In a preferred embodiment, the detection unit includes: a cylinder 14 disposed within the mounting housing 13 and fixedly connected to the mounting housing 13; a connecting plate 15 disposed on the cylinder 14 and fixedly connected to the cylinder 14; and a springback detector 16 disposed on the connecting plate 15 for detecting the strength of the precast component.

[0057] refer to Figure 2 and Figure 3In a preferred embodiment, the fixing mechanism includes: a plurality of support members 17, wherein the plurality of support members 17 are disposed on the base 1 and fixedly connected to the base 1; a pressure sensor 18, disposed inside the base 1 and fixedly connected to the base 1; and a placement plate 19, disposed on the pressure sensor 18 and fixedly connected to the pressure sensor 18.

[0058] refer to Figure 3 In a preferred embodiment, the fixing mechanism further includes: multiple electric telescopic rods 20, which are disposed within the support member 17 and fixedly connected to the support member 17; and multiple contact plates 21, which are disposed on the electric telescopic rods 20 and fixedly connected to the electric telescopic rods 20.

[0059] With this configuration, the existing technology of the springback detector 16 will not be described. When performing the detection work, the distance between the springback detectors 16 is kept to a minimum at the beginning, and then increases sequentially as the detection work progresses.

Furthermore, it ensures that the rebound detector 16 moves at consistent intervals each time during testing, guaranteeing the accuracy of the test data.

[0061] Working principle: When this device is in operation, the precast concrete slab is placed on the placement plate 19. The electric telescopic rod 20 is activated to drive the contact plate 21 to fix the precast concrete slab and prevent it from moving. Then, the hydraulic cylinder 9 is activated to move the mounting part 3 until the rebound detector 16 contacts the precast concrete slab and performs the test. After the test is completed, the hydraulic cylinder 9 retracts part of the plate, and the drive motor 4 is activated to drive the rotating part 5 to rotate. This causes the moving rack 6 to move the mounting block 11, thereby increasing the distance between the rebound detectors 16. Then, the drive motor 4 stops, and the hydraulic cylinder 9 again brings the rebound detector 16 into contact with the precast concrete slab and performs the test. The above steps are repeated once more to complete the test of the precast concrete slab.
