[0031] The support assembly 3 includes a support cross bar 31 and a rotating support 32 . The upper ends of the support cross bar 31 and the rotating support 32 are fixedly connected with a compression support rod 33 .

[0032] The first elastic clamp 63 and the second elastic clamp 67 are clamped on the top of the compression support rod 33 respectively, and then the block 35 is pressed to release the lock of the rotating bracket 32, so that the rotating bracket 32 ​​is flipped to the lower side of the bracket cross bar 31, and then the electronic data meter 7 is hung on the bottom ring of the suspension rod connector 2, the bracket cross bar 31 is tilted, and the rotating bracket 32 ​​is flipped upward. The suspension rod connector 2 is clamped by the first support frame 61 and the second support frame 62 to complete the positioning of the bracket cross bar 31, and then the support rod length adjustment bolt 34 is twisted to make the compression support rod 33 contact with the concrete structure top plate 1. After the fixation is completed, the positioning component 6 is removed, and then the pressure adjustment nut 9 is twisted to adjust the initial value of the electronic data meter 7 so that the electronic data meter 7 remains in a straightened state, which is convenient for recording the value. The electronic data meter 7 performs actual measurement without any conversion. The data is transmitted to the data receiving platform 14 through the data transmitter 8 to achieve real-time data upload.

[0034] By setting the support assembly 3, the electronic data meter 7 can be supported during the detection of the hanger connector 2, and the electronic data meter 7 can be kept pulled vertically downward. By setting the support cross bar 31 and the rotating bracket 32 ​​to be rotatably connected, the compression support rod 33 can be rotated before it conflicts with the concrete structure top plate 1. At this time, the rotating bracket 32 ​​can drive the compression support rod 33 on one side to flip, so that the electronic data meter 7 can be hung inside the hanging ring of the hanger connector 2. By setting the support rod length adjustment bolt 34 on the top of the compression support rod 33, the compression support rod 33 can be adjusted. The length of the compression support rod 33 is adjusted so that the compression support rod 33 contacts the concrete structure top plate 1, and the electronic data meter 7 is kept vertically with the concrete structure top plate 1. After the electronic data meter 7 is hung on the hanger connector 2, the compression support rod 33 is rotated upward with the rotating bracket 32 ​​as the axis, so that the clamping block 35 is rotated to the clamping groove 37 and engaged with the clamping groove 37, and then the support rod length adjustment bolt 34 can be screwed to adjust the length of the compression support rod 33 so that the compression support rod 33 contacts the bottom of the concrete structure top plate 1 tightly.

[0036] By setting a safety fixing support rod 4, the safety fixing support rod 4 supports the bracket cross bar 31 through the lateral support rod at the upper end, and the screw rod at the bottom of the electronic data meter 7 passes through the bracket cross bar 31 and the electric hydraulic hollow jack 38, and the screw rod is fixed by the pressure adjusting nut 9. The electric hydraulic hollow jack 38 can be extended to push the pressure adjusting nut 9 to drive the screw rod of the electronic data meter 7 to move, thereby applying a pulling force to the electronic data meter 7, so as to perform a pull-out test on the boom connector 2.

[0037] like Figure 3 , Figure 4 and Figure 6 As shown, the fixing buckle assembly 5 includes a fixing buckle body 51, a fixing buckle ring 52 is rotatably connected to the side of the fixing buckle body 51, and a limit locking rod 53 is rotatably connected to the upper end of the fixing buckle body 51. A cushion layer for contacting with the compression support rod 33 is arranged inside the fixing buckle ring 52, and the fixing buckle ring 52 is sleeved on the outside of the safety fixing support rod 4 and the compression support rod 33. The fixing buckle body 51 contacts with the safety fixing support rod 4, and the fixing buckle ring 52 contacts with the limit locking rod 53.

[0038] By setting a fixing buckle assembly 5, the fixing buckle assembly 5 connects the safety fixing support rod 4 with the compression support rod 33, so that the safety fixing support rod 4 fixes the bracket cross bar 31, and by setting a fixing buckle body 51 and a fixing buckle ring 52, the compression support rod 33 and the safety fixing support rod 4 can be quickly surrounded inside the fixing buckle ring 52, and then the fixing buckle body 51 and the fixing buckle ring 52 are closed, and the limit locking rod 53 is pushed downward to make the limit locking rod 53 contact with the fixing buckle ring 52 to limit the fixing buckle ring 52, thereby completing the locking of the fixing buckle body 51 and the fixing buckle ring 52, and by setting a cushion layer that contacts the compression support rod 33 inside the fixing buckle ring 52, direct contact between the fixing buckle ring 52 and the compression support rod 33 is avoided, so that the compression support rod 33 is squeezed and deformed.

[0039] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the positioning assembly 6 includes a first support frame 61 and a second support frame 62, a pair of first elastic clamps 63 are slidably connected inside the first support frame 61, one end of the first elastic clamp 63 located inside the first support frame 61 is fixedly connected to a toothed plate 64, the first support frame 61 is rotatably connected to a gear shaft 65, the second support frame 62 is fixedly connected to one end close to each other with a first elastic member 66, the second support frame 62 is slidably connected to a second elastic clamp 67, the second support frame 62 is fixedly connected to a tension spring 68, the second elastic clamp 67 is elastically connected to an elastic locking block 69, Z-shaped limiting grooves 610 are provided on both sides of the second support frame 62, and the second elastic clamp 67 is fixedly connected to a magnet 611 at one end close to the clamp.

[0040] By setting the positioning component 6, the first elastic clamp 63 and the second elastic clamp 67 are respectively engaged with the top of the compression support rod 33, and the first support frame 61 and the second support frame 62 are in contact with the hanger connector 2, so that the middle part of the support cross bar 31 is kept vertical with the hanger connector 2, and the support cross bar 31 is kept balanced. After the compression support rod 33 completes the positioning of contacting with the concrete structure top plate 1, the handle of the gear shaft 65 is rotated to make the first elastic clamp 63 retract into the first support frame 61 to release the clamping of the compression support rod 33, so as to remove the first support frame 61, and then push the elastic clamping block 69 to move upward, so that the elastic clamping block 69 slides in the Z-shaped limit groove 610, and the second support frame 62 is pulled by the tension spring 68 to release the conflict with the hanger connector 2, and then the second elastic clamp 67 is manually pulled to release the clamping of the compression support rod 33, so as to remove the positioning component 6 to avoid affecting the pull-out test of the electronic data meter 7 on the hanger connector 2.

[0041] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the first support frame 61 is in conflict with the second support frame 62, a pair of first elastic clamping claws 63 are respectively clamped on the top of the compression support rod 33 at the upper end of the rotating bracket 32, a pair of toothed plates 64 are meshed and connected with the gear shaft 65, and the side of the gear shaft 65 is provided with a handle extending to the outside of the first support frame 61, and the ends of the first elastic members 66 close to each other are fixedly connected to the first support frame 61; the first support frame 61 and the second support frame 62 are provided with an arc groove matching the boom connector 2 in the middle, and the arc groove It is used to make the first support frame 61 and the second support frame 62 fit with the suspension rod connector 2, the second elastic clamp 67 is clamped on the top of the compression support rod 33 located on the upper side of the bracket cross bar 31, the tension spring 68 is fixed to one end of the second elastic clamp 67 located inside the second support frame 62, and a rectangular shell is provided on the outer side of the elastic clamp block 69 for pushing the elastic clamp block 69 to move upward, the elastic clamp block 69 is slidably connected to the inside of the Z-shaped limiting groove 610, and the magnet 611 is magnetically adsorbed and connected to the compression support rod 33.

[0042] By setting the first elastic clamping claw 63 to be clamped and connected with the compression support rod 33 at the upper end of the rotating bracket 32, after the first support frame 61 and the second support frame 62 collide with each other, the compression support rod 33 and the suspension rod connector 2 can be kept parallel by fitting with the suspension rod connector 2. Then, after the compression support rod 33 and the concrete structure top plate 1 collide with each other, the electric hydraulic hollow jack 38 can vertically pull the electronic data meter 7 and the suspension rod connector 2 to ensure the accuracy of the test. By setting the tooth plate 64 and the gear shaft 65, after holding the middle part of the first support frame 61, the gear shaft 65 can be rotated to pull the first elastic clamping claw 63 to move inside the first support frame 61 to release the clamping of the compression support rod 33. Then, the first support frame 61 and the first elastic clamping claw 63 can be removed without affecting the compression support rod 33 and the suspension rod connector 2. By setting the first elastic member 66, the first elastic clamping claw 63 can be easily pushed to reset.

[0043] The tension spring 68 arranged inside the second support frame 62 can pull the second elastic clamp 67 into the second support frame 62, so that the second support frame 62 and the suspension rod connector 2 are no longer in conflict. By setting an elastic blocking block 69, it can slide inside the Z-shaped limiting groove 610 to release the limitation of the second elastic clamp 67, so that the tension spring 68 can pull the second support frame 62 to move. By setting a magnet 611 inside the second elastic clamp 67, after the second elastic clamp 67 clamps the first elastic clamp 63, the magnet 611 can absorb the compressive support rod 33 to position the second elastic clamp 67, so as to avoid the second support frame 62 sliding down due to gravity before conflicting with the first support frame 61, resulting in position displacement.

[0044] like Figures 1 to 3As shown, the boom connector 2 uses an inner thread sleeve welded lifting ring, wherein the stiffness of the inner thread sleeve is greater than the stiffness of the boom, wherein the inner diameter of the lifting ring is greater than the outer diameter of the hook at the top of the electronic data meter 7, and the operating platform 10 fixes and supports the support assembly 3 by safely fixing the support rod 4 and the fixing buckle assembly 5, and the data receiving platform 14 receives the data transmitted by the electronic data meter 7 in real time through the data transmitter 8.

[0045] By setting the stiffness of the inner thread sleeve of the hanger connector 2 to be greater than the stiffness of the hanger, the hanger connector 2 will not be deformed by the tension of the electronic data meter 7, thereby ensuring the accuracy of the test. The inner diameter of the lifting ring is larger than the outer diameter of the hook on the top of the electronic data meter 7, which facilitates the hanging of the electronic data meter 7. By setting up an operating platform 10, it is convenient to fix and support the support component 3, and it is also convenient for the staff to install the support component 3. The data receiving platform 14 receives the data of the data transmitter 8 in real time, and then uploads it to the regulatory department through the network to record and evaluate the test results.

[0046] During operation, the mobile platform vehicle 12 is first moved to the bottom of the inspection location, and then the telescopic support frame 11 pushes the operating platform 10 up, allowing the worker to approach the bottom of the concrete structure top plate 1. The worker installs the boom connector 2 to the bottom of the concrete structure top plate 1, and then clamps the first elastic clamp 63 and the second elastic clamp 67 on the top of the compression support rod 33 respectively, and flips the rotating bracket 32 ​​to close the first support frame 61 and the second support frame 62 once, and positions the direction of the second support frame 62, and then presses the card block 35 to release the lock on the rotating bracket 32, so that the rotating bracket 32 ​​is flipped to the lower side of the bracket cross bar 31, and then the electronic The data meter 7 is hung on the bottom ring of the boom connector 2, the bracket cross bar 31 is tilted manually, and then the bracket 32 ​​is turned and rotated to the top of the bracket cross bar 31 and fixed, and the boom connector 2 is clamped by the first support frame 61 and the second support frame 62 to complete the positioning of the bracket cross bar 31, and then the support rod length adjustment bolt 34 is twisted to make the compression support rod 33 contact with the concrete structure top plate 1. After the fixation is completed, the positioning component 6 is removed to avoid the test data being affected, and then the pressure adjustment nut 9 is twisted to adjust the initial value of the electronic data meter 7 to 10KG, so that the electronic data meter 7 remains in a straightened state, and it is convenient to record the value;

[0047] After the support cross bar 31 is positioned, the transverse support rod of the safety fixing support rod 4 is inserted into the side of the support cross bar 31, and then the safety fixing support rod 4 is fixed to the compression support rod 33 through the fixing buckle assembly 5, so that the safety fixing support rod 4 can fix the support assembly 3, ensure the stability of the support assembly 3, support the support assembly 3, prevent the boom connector 2 from being pulled off, ensure the safety of the workers, and then use the jack electronic remote control 13 to control the extension of the electric hydraulic hollow jack 38 for testing.
