[0002] Intelligent cranes are lifting equipment that integrates advanced automation technology, sensor technology, information technology, control technology and other high-tech technologies based on traditional cranes. It can realize multiple functions such as automatic control, precise operation, status monitoring and fault diagnosis. In the process of lifting pipes by intelligent cranes, the lifting device is indispensable. Pipes are generally cylindrical and have a relatively smooth surface. If they are directly lifted by the crane hook, they are prone to slipping. The friction between the lifting device and the pipe is used to provide appropriate clamping for the pipe to prevent the pipe from shaking, rolling or falling during the lifting process, thereby ensuring the safety of the lifting work and the integrity of the pipe.

[0003] In the prior art, when using the pipe lifting sling of the intelligent crane, it is sometimes necessary to rotate the pipe to a specific angle for placement.

A plurality of rolling grooves 316 are movably embedded with rolling balls 317 inside. The plurality of rolling balls 317 distributed on each circumference form a group. The outer surfaces of the two groups of rolling balls 317 are in contact with the top and the inner top surface of the rotating box 301 respectively. The output end of the forward and reverse motor 309 movably penetrates to the bottom of the mounting plate 308. The outer surface of the limiting telescopic rod 310 It is movably embedded in the T-block 304, and the outer surface of the connecting plate 314 is fixedly mounted on the inner wall of the fixing frame 307.

The bottom ends of the plurality of supporting rods 322 are all fixedly mounted on the top of the rotating box 301. A hydraulic system 5 is arranged inside the control box 2, and a battery 6 is installed inside the control box 2 through an auxiliary plate. A PLC controller 7 is arranged on the rear wall inside the control box 2, and a wireless communication module 8 is arranged on the rear wall inside the control box 2 near the PLC controller 7.

[0023] In this embodiment, when in use, the hydraulic pipe hanger 1, the forward and reverse motor 309, the photoelectric detector 315, the inclination sensor 405, the hydraulic rod 413, the hydraulic system 5, the battery 6, the wireless communication module 8 and the PLC controller 7 are electrically connected. The PLC controller 7 is wirelessly connected to the external control system through the wireless communication module 8, and the battery 6 is used to power other devices. A lifting ring is installed on the top of the fixed frame 307, and the lifting ring is connected to the intelligent crane through bolts, so that the rotating component 3, the inclination component 4 and the hydraulic pipe hanger 1 are connected to the crane together, and the hydraulic cylinder in the hydraulic pipe hanger 1 is started to drive the hydraulic pipe hanger 1 to open and then close, so as to clamp and fix the pipe. The inner wall of the clamp of the hydraulic pipe hanger 1 is sprayed with a polyurethane coating. The polyurethane coating has good wear resistance and elasticity, can provide good friction, thereby enhancing the ability to clamp the pipe, and can increase the friction between the hydraulic pipe hanger 1 and the pipe, increase the clamping tightness, and improve the stability during the lifting process. When the pipe is hoisted to the appropriate position, the forward and reverse motor 309 is started, and the output end of the forward and reverse motor 309 drives the limit telescopic rod 310 to rotate inside the T-block 304, and drives the driving gear 311 to rotate in the movable ring 319.

The light emitted by the light source passes through the code disk 313 and is received by the photoelectric detector 315. Since the transparent and opaque areas on the code disk 313 are arranged alternately, the light signal received by the photodetector 315 will produce periodic changes, forming a pulse signal. The rotation angle is determined by calculating the number of pulses, and the angle rotation data is transmitted to the PLC controller 7. The threshold of the rotation angle data is set in advance inside the PLC controller 7. The PLC controller 7 will identify and compare according to the received rotation data. When the pipe is rotated to a suitable angle, the PLC controller 7 will control the forward and reverse motors 309 to automatically shut down and stop rotating. At the same time, the PLC controller 7 will wirelessly transmit the data to the external control system, which is convenient for the staff to check the rotation angle, thereby achieving the effect of adjusting the rotation angle of the hydraulic pipe hanger 1. With the cooperation of the rotating component 3 and the PLC controller 7, the rotation angle of the hydraulic pipe hanger 1 can be accurately controlled, and the pipe can be accurately rotated to the required specific angle. During the rotation process, compared with the rotation of the crane, the shaking produced by the rotating component 3 is smaller, which can better maintain the stability of the pipe.The problem that the pipe lifting sling of the intelligent crane is generally driven by the rotation of the crane during use, and the rotation accuracy is relatively poor, which easily causes the pipe rotation angle to deviate, resulting in inaccurate subsequent docking of the pipe, thereby affecting the subsequent installation quality.

[0025] In this embodiment, when in use, when it is necessary to adjust the inclination angle of the pipe to facilitate docking, the two hydraulic rods 413 are started, and the push-pull plate 411 is pushed downward at the same time, and the clamping rod 414, the fixed rod 320 and the positioning rod 412 are driven to move downward at the same time, and the fixed rod 320 drives the movable ring 319 to move downward, thereby pulling the driving gear 311 to slide out of the gear groove 312, and making the teeth at the bottom of the driving gear 311 mesh with the teeth of the bevel gear 406, and the positioning rod 412 is moved out of the positioning hole 410, and the positioning sleeve 407 and the bevel gear 406 lose the limit. In addition, the clamping rod 414 moves downward, so that one end of it is inserted into the clamping hole, and the fixing frame 307 is connected with the rotating box 301 through the clamping rod 414, and the rotating box 301 is limited to prevent the rotating box 301 from accidentally rotating when the hydraulic pipe hanger 1 is subsequently tilted, thereby affecting the accuracy of the inclination angle and position of the pipe. At this time, the driving gear 311 is not meshed with the gear groove 312 , but is meshed with the bevel gear 406 , the bottom of the bevel gear 406 is meshed with the arc gear 403 , and the bottom end of the limiting telescopic rod 310 is pulled into the gear groove 312 . Then, the forward and reverse motor 309 is started to drive the limited telescopic rod 310 and the driving gear 311 to rotate, driving the bevel gear 406 and the positioning sleeve 407 to rotate on the outer surface of the reinforcement rod 408, and further driving the arc gear 403 to rotate with the fixed shaft 402 as the axis, thereby driving the adjustment frame 401 to slowly rotate with the fixed shaft 402 as the axis, so that the control box 2 and the hydraulic pipe hanger 1 slowly tilt, further driving the pipe to tilt, and at the same time, the inclination sensor 405 detects the inclination angle of the adjustment frame 401, and transmits the detected inclination data to the PLC controller 7 for identification and comparison. When the inclination data meets the set value range, the PLC controller 7 will control the forward and reverse motor 309 to turn off, so as to facilitate the adjustment of the pipe to the inclination state matching the installation position.

[0026] The effect and working principle of the whole mechanism are as follows: when in use, the forward and reverse motor 309 is started to drive the limit telescopic rod 310 and the driving gear 311 to rotate, and the T-block 304 and the fixed plate 302 are driven to rotate through the gear slot 312 at the same time, and further drive the rotating box 301, the tilting component 4, the control box 2 and the hydraulic pipe hanger 1 to rotate slowly together, so that the clamped pipe rotates slowly.

When the pipe rotates to a suitable angle, the PLC controller 7 will control the forward and reverse motor 309 to automatically turn off and stop rotating. At the same time, the PLC controller 7 transmits the data wirelessly to the external control system, which is convenient for the staff to check the rotation angle, thereby achieving the effect of adjusting the rotation angle of the hydraulic pipe hanger 1. With the cooperation of the rotating assembly 3 and the PLC controller 7, the rotating angle of the hydraulic pipe hanger 1 can be precisely controlled, and the pipe can be precisely rotated to the required specific angle. During the rotation process, the shaking of the rotating assembly 3 is small, which can better maintain the stability of the pipe. Start the two hydraulic rods 413, and push the push-pull plate 411 downward at the same time, and drive the clamping rod 414, the fixed rod 320 and the positioning rod 412 to move downward at the same time. The fixed rod 320 drives the movable ring 319 to move downward, thereby pulling the driving gear 311 to slide out of the gear groove 312 and mesh with the bevel gear 406. The positioning rod 412 moves out of the positioning hole 410, and the positioning sleeve 407 and the bevel gear 406 lose their limit. In addition, the clamping rod 414 moves downward so that one end of it is inserted into the clamping hole. Then, the forward and reverse motor 309 is started to drive the limiting telescopic rod 310 and the driving gear 311 to rotate, driving the bevel gear 406 and the positioning sleeve 407 to rotate on the outer surface of the reinforcement rod 408, and further driving the arc gear 403 to rotate, thereby driving the adjustment frame 401 to slowly rotate with the fixed axis 402 as the axis, so that the control box 2 and the hydraulic pipe hanger 1 slowly tilt, further driving the pipe to tilt, and at the same time, the inclination sensor 405 detects the inclination angle of the adjustment frame 401, and transmits the detected inclination data to the PLC controller 7 for identification and comparison. When the inclination data meets the set numerical range, the PLC controller 7 will control the forward and reverse motor 309 to turn off, thereby achieving the effect of adjusting the inclination angle of the pipe and increasing the lifting flexibility of the hanger.
