The working principle is as follows: when the device is used, a user starts the motor 17, the motor 17 drives the flexible clamping rollers 15 to rotate through the meshing of the second gear 20 and the first gear 19, the third transmission shaft 16 drives the flexible clamping rollers 15 to rotate, the user conveys steel bars to be detected to the inner part of the clamping blocks 41 arranged in the circumferential array through the matching of the bracket and the flexible clamping rollers 15, the first helical gear 25 drives the second helical gear 26 to rotate through the mutual meshing of the second gear 20, the third gear 21 and the fourth gear 23, the second limit shaft 27 drives the second transmission shaft 13 to rotate through the belt, the transmission gear 29 drives the driven gear 30 to rotate through the rotation of the second transmission shaft 13, the positioning shaft 42 drives the limit rod 40 to move towards the inner part of the fourth fixing frame 28 through the rotation of the driven gear 30, the clamping blocks 41 arranged in the circumferential array can tighten and limit the steel bars, and the steel bars can stably enter the inner part of the detection box 2 to be detected, after the reinforcing bar is fastened at clamp splice 41, drive gear 29 just can't rotate, under the great torsion that two 13 transmission shafts produced, make hemisphere fastener 48 retract to the inboard of two 13 transmission shafts, and release telescopic link 43, make push rod 45 inlay the inboard at spacing hole 52, two 13 of its transmission shaft alright continue to rotate, drive transmission shaft 10 through drive belt 11 and rotate, the fixed swing arm 31 of normal running fit of transmission shaft 10 and activity swing arm 32 make lever 7 drive detection pole 5 reciprocate, through the cooperation of detection pole 5 and detection head 36 that is linear array and arranges, carry out the detection of multiple spot to the reinforcing bar, guarantee detection accuracy.

To sum up, the strength detection device for the steel structure of the large building is characterized in that a user places steel bars to be detected on a bracket through the matching of the flexible clamping rollers 15, the fixing frames III 14, the transmission shafts III 16 and the transmission belts II 18, the motor 17 generates power, the transmission shafts III 16 drive the flexible clamping rollers 15 to rotate under the meshing drive of the gears II 20 and the gears I19, the flexible clamping rollers 15 which are symmetrically arranged clamp and transport the steel bars, and the steel bars do not need to be manually held for detection operation; through the matching of the four fixing frames 28, the driven gear 30, the limiting rod 40 and the clamping block 41, when the reinforcing steel bar enters the clamping block 41, the driven gear 30 slightly rotates through the matching of the transmission gear 29 and the driven gear 30, the positioning shaft 42 can drive the limiting rod 40 to move when the driven gear 30 rotates, the limiting rod 40 moves towards the inner side of the four fixing frames 28, and the clamping blocks 41 which are arranged in a circumferential array can clamp the reinforcing steel bar, so that the reinforcing steel bar can stably enter the detection box 2 for detection; by the cooperation of the hemisphere fastener 48 and the movable post 50 and the stopper 44 and the fixed swing arm 31, when the clamping block 41 clamps the steel bar, the transmission gear 29 can not drive the driven gear 30 to rotate, when the second transmission shaft 13 still generates a large rotating force, the hemisphere clamping piece 48 retracts to the inner part of the second transmission shaft 13, when the hemisphere clamping piece 48 moves downwards, the movable column 50 is pushed through the connecting piece 49, so that the telescopic rod 43 extends out of the second transmission shaft 13, when the second limit hole 52 protrudes out of the second transmission shaft 13, the second spring 47 generates elastic force on the second limit disc 46 to push the push rod 45 to be embedded in the second limit hole 52, so that the telescopic rod 43 cannot retract, the second transmission shaft 13 can drive the first transmission shaft 10 to rotate at a high speed through the first transmission belt 11, and the limiting slide block 33 drives the lever 7 to move up and down through the matching of the fixed swing arm 31 and the movable swing arm 32, so that the detection rod 5 drives the detection head 36 to perform multi-point detection on the steel bars.
