Description

Technical Field

[0002] An intelligent crane is a hoisting equipment that integrates a variety of high-techs such as advanced automation technology, sensor technology, information technology, and control technology on the basis of a traditional crane. It can achieve various functions such as automatic control, precise operation, status monitoring, and fault diagnosis. During the process of hoisting pipes, a spreader is essential. Pipes are generally cylindrical with a relatively smooth surface. If directly hoisted with the hook of a crane, it is very easy to slip. By utilizing the friction between the spreader and the pipe, appropriate clamping is provided for the pipe to prevent the pipe from shaking, rolling, or falling during hoisting, thereby ensuring the safety of the hoisting work and the integrity of the pipe.

[0003] In the prior art, during the use of the intelligent crane pipe hoisting spreader, sometimes it is necessary to rotate the pipe to a specific angle for placement.

The rotation accuracy of this rotation method is relatively poor, it is very difficult to achieve precise control, and it is easy to cause deviation in the rotation angle of the pipe, resulting in inaccurate subsequent docking of the pipe, thereby affecting the subsequent installation quality.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. When the present invention is in use, start the forward and reverse motor to drive the limit telescopic rod and the driving gear to rotate. Drive the T-shaped block, the fixing plate and the rotating box to rotate through the gear groove, and then drive the hydraulic pipe sling and the pipe to slowly rotate. When the T-shaped block rotates, the code disk rotates together. The photoelectric detector receives the optical signal to form a pulse signal, calculates the rotation angle, and transmits the data to the PLC controller. When the pipe rotates to a suitable angle, the PLC controller will control the forward and reverse motor to automatically turn off, so as to achieve the effect of adjusting the rotation angle of the hydraulic pipe sling. With the cooperation of the rotating assembly and the PLC controller, the rotation angle of the hydraulic pipe sling can be accurately controlled, and the pipe can be accurately rotated to the required specific angle.

[0019] 2. When the present invention is in use, two hydraulic rods are started to push the push-pull plate downward, driving the fixed rod and the positioning rod downward. The driving gear is slid out of the gear groove through the movable ring and meshed with the bevel gear, and the positioning rod is removed from the positioning hole. The forward and reverse motor is started to drive the limit telescopic rod and the driving gear to rotate, driving the bevel gear and the arc gear to rotate, thereby driving the adjusting frame to rotate, causing the hydraulic pipe sling and the pipe to tilt. At the same time, the tilt sensor detects the tilt angle. When the tilt data meets the set value range, the PLC controller will control the forward and reverse motor to shut down, facilitating the adjustment of the pipe to the tilted state matching the installation position. Thus, the effect of adjusting the tilt angle of the pipe is achieved, increasing the lifting flexibility of the sling and making the lifting work proceed more smoothly.

[0020] 3. When the present invention is in use, when the push-pull plate moves downward, it drives the clamping rod to move downward, and one end of it is inserted into the clamping hole to limit the rotation box, preventing the rotation box from accidentally rotating when the hydraulic pipe sling tilts later, affecting the accuracy of the tilt angle and position of the pipe. The inner wall of the clamp of the hydraulic pipe sling is sprayed with a polyurethane coating, which has good wear resistance and can provide good friction, thereby enhancing the ability to clamp the pipe.

An installation plate 308 is fixedly installed inside the fixed frame 307. A forward and reverse motor 309 is fixedly installed at the top of the installation plate 308. A limit telescopic rod 310 is fixedly installed at the output end of the forward and reverse motor 309. A driving gear 311 is fixedly installed at the bottom end of the limit telescopic rod 310. A gear groove 312 is opened at the bottom of the T-shaped block 304. A code disk 313 is arranged on the outer surface of the T-shaped block 304. A connecting plate 314 is movably sleeved on the outer surface of the T-shaped block 304 near the top. A photoelectric detector 315 is fixedly installed at the bottom of the connecting plate 314. The outer surface of the driving gear 311 meshes with the inside of the gear groove 312. A plurality of rolling grooves 316 are equally spaced and opened on the opposite sides inside the I-shaped block 306. A plurality of rolling balls 317 are movably embedded inside the plurality of rolling grooves 316. The plurality of rolling balls 317 distributed in a circle are taken as a group. The outer surfaces of the two groups of rolling balls 317 are respectively in contact with the top of the rotating box 301 and the inner top surface. The output end of the forward and reverse motor 309 movably penetrates to the bottom of the installation plate 308. The outer surface of the limit telescopic rod 310 is movably embedded inside the T-shaped block 304. The outer surface of the connecting plate 314 is fixedly installed on the inner wall of the fixed frame 307. A support groove 321 is opened on the outer surface of the fixed frame 307. A plurality of support rods 322 are movably embedded inside the support groove 321. The bottom ends of the plurality of support rods 322 are all fixedly installed on the top of the rotating box 301. A hydraulic system 5 is arranged inside the control box 2. A storage 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. A wireless communication module 8 is arranged on the rear wall inside the control box 2 near the PLC controller 7.

[0034] In this embodiment, during use, the hydraulic pipe sling 1, the forward and reverse motor 309, the photoelectric detector 315, the inclination sensor 405, the hydraulic rod 413, the hydraulic system 5, the storage battery 6, the wireless communication module 8 and the PLC controller 7 are electrically connected. The PLC controller 7 is wirelessly connected to an external control system through the wireless communication module 8, and the storage battery 6 supplies power to other devices. A lifting ring is installed at the top of the fixed frame 307, and the lifting ring is connected to the intelligent crane through bolts, so as to connect the rotating assembly 3, the inclination assembly 4 and the hydraulic pipe sling 1 to the crane. Start the hydraulic cylinder in the hydraulic pipe sling 1 to drive the hydraulic pipe sling 1 to open and then close, so as to clamp and fix the pipe. The inner wall of the clamp of the hydraulic pipe sling 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, can increase the friction between the hydraulic pipe sling 1 and the pipe, increase the clamping tightness, and improve the stability during the lifting process. When the pipe is lifted to the appropriate position, start the forward and reverse motor 309. The output end of the forward and reverse motor 309 drives the limit telescopic rod 310 to rotate inside the T-shaped block 304, and drives the driving gear 311 to rotate in the movable ring 319. The driving gear 311 meshes with the gear groove 312, and at the same time drives the T-shaped block 304 and the fixed plate 302 to rotate, further driving the rotating box 301 to rotate inside the I-shaped block 306, and driving the inclination assembly 4, the control box 2 and the hydraulic pipe sling 1 to slowly rotate together, further driving the clamped pipe to slowly rotate. The code disk 313 is a disk with transparent and opaque areas. When the T-shaped block 304 rotates, the code disk 313 also rotates accordingly. The light emitted by the light source is received by the photoelectric detector 315 after passing through the code disk 313. Since the transparent and opaque areas on the code disk 313 are arranged alternately, the optical signal received by the photoelectric detector 315 will change periodically, 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 value 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 rotates to the appropriate angle, the PLC controller 7 will control the forward and reverse motor 309 to automatically shut down and stop rotating. At the same time, the PLC controller 7 wirelessly transmits the data to the external control system, which is convenient for the staff to check the rotation angle situation, so as to achieve the effect of adjusting the rotation angle of the hydraulic pipe sling 1. With the cooperation of the rotating assembly 3 and the PLC controller 7, the rotation angle of the hydraulic pipe sling 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 generated by the rotating assembly 3 is smaller, and the stability of the pipe can be better maintained.It solves the problem that during the use of the pipe lifting sling of the intelligent crane, generally, the rotation of the pipe is driven by the rotation of the crane, and the rotation accuracy is relatively poor, which easily causes deviation in the rotation angle of the pipe, resulting in inaccurate subsequent docking of the pipe and thus affecting the subsequent installation quality. A plurality of rolling balls 317 are arranged between the I-shaped block 306 and the rotating box 301 to facilitate the better rotation of the rotating box 301 and reduce the frictional resistance.

[0035] Embodiment 2: As Figures 2-9As shown, the rotating assembly 3 includes a rotating box 301. Inside the rotating box 301, a fixed plate 302 is fixedly installed near the top surface.

At the top of the mounting plate 308, a forward and reverse motor 309 is fixedly installed. At the output end of the forward and reverse motor 309, a limit telescopic rod 310 is fixedly installed. At the bottom end of the limit telescopic rod 310, a driving gear 311 is fixedly installed. At the bottom of the T-shaped block 304, a gear groove 312 is opened. At the outer surface of the driving gear 311 near the bottom, an annular groove 318 is opened. Inside the annular groove 318, a movable ring 319 is movably embedded. On the outer surface of the movable ring 319, two fixed rods 320 are fixedly installed. The inclination component 4 includes an adjusting frame 401. Inside the adjusting frame 401, a fixed shaft 402 is movably embedded. At the top of the adjusting frame 401, an arc-shaped gear 403 is fixedly installed. Inside the adjusting frame 401, a detection groove 404 is opened. Inside the detection groove 404, an inclination sensor 405 is arranged. The outer surface of the arc-shaped gear 403 is meshed with a bevel gear 406. At the front surface of the bevel gear 406, a positioning sleeve 407 is fixedly installed. Inside the bevel gear 406 and the positioning sleeve 407, a reinforcing rod 408 is movably embedded. On the outer surface of the reinforcing rod 408, two limit rings 409 are fixedly installed. On the outer surface of the positioning sleeve 407, a plurality of positioning holes 410 are opened. At the top of the arc-shaped gear 403, a push-pull plate 411 is arranged. At the top of the push-pull plate 411 near the front surface, two positioning rods 412 are fixedly installed. The outer surfaces of the two positioning rods 412 are respectively movably embedded inside two of the positioning holes 410. At the top of the push-pull plate 411 near both sides, hydraulic rods 413 are fixedly installed. At the top of the push-pull plate 411 near the two hydraulic rods 413, clamping rods 414 are fixedly installed. The top ends of the two clamping rods 414 both movably penetrate through the top of the rotating box 301. At the outer surface of the fixed frame 307 near the support groove 321, a positioning disk 415 is fixedly installed. At the top of the positioning disk 415, a plurality of clamping holes are opened. The bottom ends of the two fixed rods 320 are respectively fixedly installed at both sides near the top of the push-pull plate 411. The outer surface of the adjusting frame 401 is movably embedded inside the rotating box 301. The two ends of the fixed shaft 402 are respectively fixedly installed at both sides inside the rotating box 301. The two ends of the reinforcing rod 408 are respectively fixedly installed at both sides inside the rotating box 301. The outer surfaces of the two limit rings 409 are respectively in contact with the other outer surface of the bevel gear 406 and the one outer surface of the positioning sleeve 407. The outer surface of the push-pull plate 411 is movably embedded inside the rotating box 301. The top ends of the two hydraulic rods 413 are both fixedly installed at the top surface inside the rotating box 301. Inside the control box 2, a hydraulic system 5 is arranged.Inside the control box 2, a storage battery 6 is installed through an auxiliary board. A PLC controller 7 is provided on the rear wall inside the control box 2, and a wireless communication module 8 is provided near the PLC controller 7 on the rear wall inside the control box 2.

[0036] In this embodiment, during use, when it is necessary to adjust the tilt angle of the pipe to facilitate docking, two hydraulic rods 413 are started, simultaneously pushing the push-pull plate 411 downward, and driving the clamping rod 414, the fixed rod 320, and the positioning rod 412 to move downward simultaneously. The fixed rod 320 drives the movable ring 319 to move downward, thereby pulling the driving gear 311 out of the gear groove 312, and causing the teeth at the bottom of the driving gear 311 to mesh with the teeth of 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 limits. In addition, the clamping rod 414 moves downward, and one end of it is inserted into the clamping hole, connecting the fixing frame 307 and the rotating box 301 together through the clamping rod 414, limiting the rotating box 301 to prevent the rotating box 301 from accidentally rotating when the hydraulic pipe sling 1 tilts later, affecting the accuracy of the tilt angle and position of the pipe. At this time, the driving gear 311 is not meshed with the gear groove 312, but meshed with the bevel gear 406, and the bottom of the bevel gear 406 is meshed with the arc gear 403. The bottom end of the limit telescopic rod 310 is pulled into the gear groove 312. Then, the forward and reverse motor 309 is started to drive the limit 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 reinforcing rod 408, further driving the arc gear 403 to rotate around the fixed shaft 402, thereby driving the adjusting frame 401 to slowly rotate around the fixed shaft 402, causing the control box 2 and the hydraulic pipe sling 1 to slowly tilt, further driving the pipe to tilt. At the same time, the tilt angle sensor 405 detects the tilt angle of the adjusting frame 401 and transmits the detected tilt angle data to the PLC controller 7 for identification and comparison. When the tilt data meets the set value range, the PLC controller 7 will control the forward and reverse motor 309 to turn off, facilitating the adjustment of the pipe to the tilt state matching the installation position. With the cooperation of the rotating assembly 3 and the tilt angle assembly 4, the effect of adjusting the tilt angle of the pipe is achieved, increasing the lifting flexibility of the sling and making the lifting work proceed more smoothly.

[0037] 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 T-block 304 rotates, the code disk 313 also rotates accordingly, and the photoelectric detector 315 receives the light signal to form a pulse signal, determines the rotation angle by calculating the number of pulses, and transmits the angle rotation data 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 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.

[0038] Among them, 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 all prior arts, and their components and usage principles are all public arts, which will not be explained in detail here.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
