Detailed Implementation

[0011] Reference Figures 1-4 The aforementioned precast beam protective layer detection device is characterized by comprising a detection device 1 and a locking nut 2 inserted above the side surface of the detection device 1. A movable base frame 3 is inserted above the side surface of the detection device 1. Movable upper frames 4 are symmetrically slidably inserted at the middle of the left and right edges of the upper surface of the movable base frame 3. A locking screw 5 is inserted at the middle of the lower edge of the front surface of each movable upper frame 4. Rotating concave wheels 6 are connected to the center of the left and right surfaces of the movable base frame 3 and the middle of the outer surface of each movable upper frame 4. A double-headed motor 7 is connected between the upper surfaces of the inner sides of two movable upper frames 4.

[0012] In use, first, fix the two steel wires to the upper surface of the precast beam using brackets. Then, the operator pulls the movable base 3 and the dual-head motor 7 outwards, while the movable base 3 slides inside the movable upper frame 4. Then, place the upper and lower rotating concave wheels 6 at the top and bottom of the steel wire rope. Then, push the movable base 3 and the movable upper frame 4 inwards so that the upper and lower rotating concave wheels 6 clamp the steel wire rope. Then, rotate the locking screw 5 to fix the movable base 3 inside the movable upper frame 4. Then, insert the detection device 1 into the lower surface of the movable base 3 and tighten it with the locking nut 2. Finally, start the dual-head motor 7 to drive the upper left and right rotating concave wheels 6 to rotate, which in turn drives the activated detection device 1 to perform the detection.

[0013] Furthermore, the detection device 1 includes a protective cover 1-1, a probe 1-2, a support column 1-3, and a threaded column 1-4. The probe 1-2 is inserted into the middle of the lower surface of the protective cover 1-1, the support column 1-3 is connected to the middle of the upper surface of the protective cover 1-1, and the threaded column 1-4 is connected to the center of the upper surface of the support column 1-3. The locking nut 2 is inserted into the threaded column 1-4.

[0014] In use, insert the threaded post 1-4 through the movable base 3 and tighten the locking nut 2 onto the threaded post 1-4. At the same time, the support post 1-3 and the locking nut 2 cooperate to fix the protective cover 1-1. Finally, turn on the probe 1-2 to perform the test.

[0015] Furthermore, the movable base frame 3 includes a crossbeam 3-1, a through hole 3-2, a post 3-3, and a plate 3-4. The crossbeam 3-1 has a through hole 3-2 in the middle of its upper surface. The crossbeam 3-1 has a post 3-3 connected to the middle of its left and right sides. The crossbeam 3-1 has plates 3-4 symmetrically connected to the middle of its left and right edges. The plates 3-4 are T-shaped. The rotating concave wheel 6 is inserted into the post 3-3. The post 3-3 and the rotating concave wheel 6 are connected to each other by bearings. The threaded post 1-4 is inserted through the through hole 3-2.

[0016] In use, first insert the threaded post 1-4 through the through hole 3-2 and fix it with the lock nut 2. When pulling the crossbeam 3-1, the insert plate 3-4 slides in the movable upper frame 4 to adjust the distance between the upper and lower rotating concave wheels 6. When moving, rotating the concave wheels 6 on the insert post 3-3 can drive the probe 1-2 to move.

[0017] Furthermore, the active shelf 4 includes a square tube 4-1, a partition 4-2, a threaded opening 4-3, and a retaining ring 4-4. The partition 4-2 is connected to the upper middle part of the inside of the square tube 4-1. The threaded opening 4-3 is provided at the lower middle part of the front surface of the square tube 4-1. The retaining ring 4-4 ​​is inserted around the lower edge of the inner side surface of the square tube 4-1. The locking screw 5 is inserted into the threaded opening 4-3. The insert plate 3-4 is inserted into the middle of the lower surface of the square tube 4-1. The square tube 4-1 is L-shaped. The rotating end of the dual-head motor 7 penetrates the square tube 4-1 and is connected to the rotating concave wheel 6.

[0018] When in use, when the double-headed motor 7 and the crossbeam 3-1 are pulled, the insert plate 3-4 slides inside the square tube 4-1. At the same time, the retaining ring 4-4 ​​prevents the insert plate 3-4 from sliding out of the square tube 4-1. Meanwhile, the partition plate 4-2 prevents the insert plate 3-4 from being inserted too deeply, which would cause the upper and lower rotating concave wheels 6 to collide and be damaged. When fixing the insert plate 3-4, the locking screw 5 is rotated in the threaded opening 4-3 to clamp the insert plate 3-4.

[0019] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
