[0002] With the development of modern bridge construction, the span and bearing capacity of bridges are constantly increasing, the size of the substructures such as piers and towers is getting bigger and bigger, and the size and weight of the steel skeleton are also significantly increased. At the same time, some complex concrete components have clear requirements for the location of steel bar joints, resulting in the frequent use of large diameter and super-long steel bars.

[0003] The traditional technical solution for steel bar installation construction is to bundle the semi-finished steel bars and then lift them to high altitude with a crane. By installing an inclination sensor on the steel bar, the posture of the steel bar is monitored in real time, and then the installation and positioning are performed manually with the cooperation of the crane. The disadvantage of this method is that the process takes a long time, there are many high-altitude operations, and the safety risks are great.

[0050] In order to lift the steel bar segment, a lifting mechanism is provided, including a supporting hanging plate 1 in the shape of a regular octagon, on the upper surface of which 8 lifting rings 11 are installed in a circular array, the 8 lifting rings 11 are connected to the hook on the crane through steel wire ropes, and a tension sensor 12 is provided on the surface of the steel wire rope, which is used to monitor the tension of the steel wire rope in real time during the lifting process to prevent it from exceeding the safe working load.

[0051] By setting up the support hoisting plate 1, which serves as a connecting component between the crane and the steel bar segment, the steel bar segment has space for posture adjustment during the lifting process. At the same time, by setting up a tension sensor 12, the tension of the wire rope is monitored, which makes it easier to make the force distribution of each lifting point uniform, while avoiding overload, and can cause an alarm to ensure safety.

[0052] In order to monitor the inclination angle and rotation posture of the steel bar segment, the monitoring mechanism includes an acoustic wave sensor 2. The acoustic wave sensor 2 measures the distance by emitting ultrasonic pulses and receiving reflected echoes. At the same time, when the distance is too close, the acoustic wave sensor 2 can issue an early warning to prevent collision.

[0053] In order to drive the acoustic wave sensor 2 to move along the surface of the steel bar segment, the monitoring mechanism also includes a support ring 201 fixedly installed at the bottom of the support hanging plate 1, and grooves 202 are provided on the inner and outer surfaces of the support ring 201. The outer surface of the support ring 201 is slidably connected with a mounting block 203, and the inner surface of the mounting block 203 is symmetrically installed with positioning sliders 204. The surface distribution of the two positioning sliders 204 is slidably engaged with the inner walls of the two grooves 202. A through hole 205 is provided on the surface of one of the positioning sliders 204, and a driving gear 206 is installed on the inner wall of the through hole 205 through a bearing. The groove 202 located on one side of the outer surface of the support ring 201 An annular rack 207 is fixedly installed on the inner wall of 02, and the driving gear 206 is meshed with the annular rack 207.

One end of the output shaft of the driving motor 208 is fixedly sleeved with the axis of the driving gear 206 through a rotating shaft. The rotation of the output shaft of the driving motor 208 drives the driving gear 206 connected thereto to rotate through the rotating shaft. The rotation of the driving gear 206 drives it to move in a circle along the surface of the annular rack 207 through the meshing with the annular rack 207, and the movement of the positioning slider 204 in the groove 202 makes the mounting block 203 move in a circle along the surface of the support ring 201.

The telescopic plate 210 is slidably engaged with the inner wall of the mounting block 203, and the acoustic wave sensor 2 is installed on the lower surface of the telescopic plate 210. The telescopic plate 210 connected to it is driven to move along the inner wall of the mounting block 203 by the extension and contraction of the piston rod of the pushing cylinder 209, so that the distance between the acoustic wave sensor 2 and the steel bar segment can be adjusted according to needs, so that the acoustic wave sensor 2 can better monitor its balance.

[0055] By setting up a monitoring mechanism, the posture of the steel bar segment can be monitored only by the circular motion of the ultrasonic sensor 2 along the supporting ring 201, and at the same time, it is avoided to disassemble and install the inclination sensor on the steel bar segment multiple times, thereby reducing manpower loss, avoiding dangers in high-altitude operations, ensuring employee safety, and thus improving construction efficiency. When the ultrasonic sensor 2 detects that the distance is too close, it will also issue an alarm to avoid collision during the adjustment process, thereby improving safety.

One end of the output shaft of the first motor 313 is fixedly sleeved with one end of the first screw 314, and the inner wall of the first slider 303 is threadedly sleeved with the surface of the first screw 314. The rotation of the output shaft of the first motor 313 drives the first screw 314 connected thereto to rotate, and the rotation of the first screw 314 drives the first slider 303 to move on the surface of the slide rail 302.

[0060] In order to drive the second slider 304 and the third slider 305 to move, a second motor 325 and a third motor 326 are fixedly installed on the inner surface of the supporting hanging plate 1, and a second screw 327 and a third screw 328 are respectively installed on the inner surface of the supporting hanging plate 1 through bearings.

The inner wall of the block 329 is respectively threadedly connected to the surface of the first screw 314 and the second screw 327. The rotation of the output shaft of the second motor 325 drives the second screw 327 connected thereto to rotate. The rotation of the second screw 327 drives the L-shaped moving block 329 connected thereto to move. The movement of the L-shaped moving block 329 drives the second slider 304 to move along the surface of the slide rail 302 through the second wire wheel 321.
