Description

Technical Field

[0001] The utility model relates to the field of crane hooks, in particular to an anti-unhooking intelligent control device for crane hooks. Background Art

[0002] In modern industry and construction, cranes, as an important lifting equipment, are widely used in scenarios such as material handling and construction. However, during the use of cranes, hook unhooking is a common and dangerous problem.

[0003] Traditional crane hooks usually rely on simple structures to carry heavy objects, lacking effective anti-unhooking measures. When the hook is affected by severe vibration, impact or improper operation during the lifting process, the heavy objects on the hook are easy to fall off, causing serious safety accidents, resulting in casualties and property losses.

[0004] At present, a Chinese utility model patent application with publication number CN220011869U and publication date November 14, 2023 proposes a remote-controlled anti-unhooking device for a crane hook, comprising: a connecting block, fixedly installed at the opening of the hook; an anti-unhooking mechanism, comprising a connecting part, a blocking section and a rotating section; the connecting part is hinged to the connecting block; the blocking section and the rotating section are arranged on both sides of the connecting part, and one end of the blocking section is fixedly connected to the connecting part, and one end of the rotating section is fixedly connected to the connecting part; the blocking section is located in the opening of the hook; a lifting mechanism, installed on the outside of the pulley block; the lifting mechanism includes a lifting rod for linear sliding in a vertical direction, and a power device for driving the lifting rod to slide; a connecting rope, one end of which is tied to the lifting rod, and the other end is tied to the end of the rotating section away from the connecting part.

[0005] When in use, the lifting rod is raised and lowered and the connecting rope is used to pull the rotating section of the anti-unhooking device to rotate, thereby driving the opening and closing of the blocking section; the power device that drives the lifting rod to rise and fall can control the opening and closing of the anti-unhooking device by remote control.

[0006] Regarding the above-mentioned related technologies, since the use environment of the hook is relatively complex, if the parking position of the hook is inaccurate, workers usually pull the hook to the accurate position. If during the pulling process, the worker accidentally squeezes the connecting rope, or the cable bends and deforms, the rotating section will be pushed to a certain height, causing the blocking section to rotate and leave the protective position, which may easily pose a safety hazard.

[0017] Optionally, the anti-slip mechanism further includes an electromagnet, which is disposed on the mounting platform and is electrically signal-connected to the control terminal.

[0018] By adopting the above technical solution, when the gear lever needs to be rotated, the electromagnet is energized, the electromagnet adsorbs the first pawl, and the shaft resumes rotation, thereby realizing the rotation of the gear lever and the switching of the locking mode, making the device more convenient to operate.

[0019] Optionally, the rotating assembly further includes a second ratchet, a second rocker and a second pawl, the second rocker is rotatably disposed on the mounting platform, the second pawl is disposed on the second rocker, and the second ratchet is disposed on the rotating shaft.

The hook 100 and the anti-unhooking mechanism 300 are both mounted on the mounting platform 200. A cable for suspending the hook 100 is installed on the upper end of the mounting platform 200. The anti-unhooking mechanism 300 is used to limit the hook 100 for protection, thereby reducing the interference of the external environment on the barrier rod 312 and improving the safety of the device.

[0041] When it is necessary to perform an anti-unhooking operation on the hook 100, the rope for hanging the item is hung on the hook 100, and then the blocking rod 312 is rotated to make the blocking rod 312 overlap with the hook 100, forming a closed loop between the blocking rod 312 and the hook 100, and then fixing the hanging rope on the hook 100. When the hanging rope swings, the blocking rod 312 stops rotating under the rotation limit of the first ratchet 313, the first pawl 314 and the first rocker arm 315, and the second pawl 318, the second ratchet 316 and the second rocker arm 317, thereby locking the blocking rod 312 and reducing the possibility of the hanging rope detaching from the hook 100.

[0042] Reference Figures 1 to 3 The slider 360 is slidably set on the blocking rod 312, the block 350 is set on the blocking rod 312, one blocking rod 312 corresponds to one slider 360 and one block 350, and the connecting rod 340 is set on the slider 360; the motor 370 is set on the mounting platform 200, the rotating shaft 311 is drivingly connected to the output shaft of the motor 370, the control terminal 380 is electrically connected to the motor 370, and the control terminal 380 can be a terminal device such as a mobile phone, a controller, or a server; the electromagnet 390 is set on the mounting platform 200, and the electromagnet 390 is electrically connected to the control terminal 380.

[0043] The blocking rod 312 abuts against the hanging rope, and at the same time, the connecting rod 340 slides to a position in contact with the hook 100, so that the connecting rod 340 further protects and supports the blocking rod 312, thereby improving the supporting strength of the blocking rod 312; when the blocking rod 312 needs to be rotated, the electromagnet 390 is energized, and the electromagnet 390 adsorbs the first pawl 314 and the second pawl 318 to restore the rotation of the shaft 311, thereby realizing the rotation of the blocking rod 312 and the switching of the locking mode, making the device more convenient to operate.

[0044] Reference Figure 3 The manual assembly 320 includes a pull ring 321, a pull rod 322, a pull rope 323 and a tension spring 324. The pull rod 322 is slidably set on the mounting platform 200, one end of the pull rope 323 is connected to the pull rod 322, and the other end of the pull rope 323 is connected to the first pawl 314 and the second pawl 318. The tension spring 324 is sleeved on the pull rod 322, one end of the tension spring 324 is connected to the mounting platform 200, and the other end of the tension spring 324 is connected to the pull rod 322, and the pull ring 321 is set on the pull rod 322.

[0045] When the device loses power unexpectedly, the pull ring 321 can be pulled to make the pull rod 322 drive the pull rope 323, and the pull rope 323 can lift the first pawl 314 and the second pawl 318, so that the rotating shaft 311 can resume rotation. When locking is required, the pull ring 321 is released, and the first pawl 314 and the second pawl 318 can be reset again to achieve locking, so that the device can continue to be used in the event of a power outage, thereby improving the reliability of the device.

[0046] Reference Figure 1 and Figure 4 The limit assembly 330 includes a limit rod 331, a limit block 332 and a limit spring 333. A set of limit assemblies 330 corresponds to a blocking rod 312. The limit block 332 is slidably set on the mounting platform 200. One end of the limit spring 333 is connected to the limit block 332, and the other end of the limit spring 333 is connected to the mounting platform 200. The limit rod 331 is set on the rotating shaft 311.

[0047] After the baffle rod 312 is fixed, the limit rod 331 contacts the limit block 332, which can assist in positioning the baffle rod 312. At the same time, when the baffle rod 312 is forced to rotate, the limit rod 331 abuts against the limit block 332, causing the baffle rod 312 to stop rotating, thereby reducing the locking burden of the rotating assembly 310 and improving the safety of the device.
