Description

Technical Field

[0001] The invention belongs to the technical field of hook guide structures, and in particular relates to a safety guide structure for a crane hook. Background Art

[0002] The hook is the most common type of lifting device in lifting machinery. The hook is often suspended from the wire rope of the lifting mechanism with the help of components such as a pulley block. The heavy objects that need to be lifted with the hook are generally large in size and weight. To ensure the safety of the lifting, the lifting is usually carried out at the center of gravity of the lifting object. This requires adjusting the hook to facilitate the movement of the hook to the center of gravity of the lifting object. The hook itself is heavy and large in size. Therefore, relying on manpower to adjust the hook is not only time-consuming and labor-intensive, but also due to inertia, the hook is prone to excessive movement or excessive speed, which can easily collide with the heavy object, causing damage to the lifted object, or hit construction workers nearby, posing a major safety hazard. Therefore, in order to address the above safety situations, a structure is needed to limit the movement of the hook when lifting heavy objects. The structure can extend the hook in the desired direction to avoid damage to the heavy object and personnel, thereby improving the safety of the hook. Summary of the Invention

[0003] The purpose of the present invention is to provide a safety guide structure for a crane hook. By setting a guide structure used in conjunction with the hook, the movement of the hook is restricted, thereby solving the problem that the existing hook is prone to collision with people or goods and is prone to deviation when lifting and hanging heavy objects.

A telescopic rod 4 is rotatably connected to the outer arc surface of the arc slide 3. A weight connection structure 5 is fixed to the end of the telescopic rod 4 away from the arc slide 3.

[0036] A guide tube 6 is passed through the center of the support plate 1 and is matched with the hook 2. The guide tube 6 is fixedly connected to the support plate 1. A guide sleeve 7 is fixed to the top of the guide tube 6 by bolts. A guide ring 8 is fixed to the outer surface of the guide tube 6. A steering adjustment structure 9 is slidably connected to the guide ring 8.

[0037] The heavy object connection structure 5 includes a connecting sleeve 501, one end of which is fixedly connected to the telescopic end of the telescopic rod 4, and a ball seat 502 is fixed to the other end of the connecting sleeve 501. A sphere 503 is rotatably connected inside the ball seat 502. A connecting rod 504 is fixed on the spherical surface of the sphere 503 located outside the ball seat 502. A suction cup 505 is fixed to the end of the connecting rod 504 away from the sphere 503, and a magnet 506 is fixed inside the suction cup 505.

[0038] The support plate 1 includes two semicircular support frames 101 fixed together by bolts. A semicircular sleeve 102 passes through the center of the two semicircular support frames 101. The two semicircular sleeves 102 constitute a guide tube 6 that cooperates with the guide sleeve 7. An arc-shaped slide 103 that cooperates with the arc-shaped slide seat 3 is fixed on the outer circular surface of the semicircular support frame 101.

[0039] The telescopic rod 4 includes an outer sleeve rotatably connected to the arc slide 3. The end of the outer sleeve away from the arc slide 3 is slidably connected to a guide rod extending to the inside of the outer sleeve. The end of the guide rod away from the outer sleeve is fixedly connected to the connecting sleeve 501. A fastening bolt passes through the outer circular surface of the end of the outer sleeve away from the arc slide 3. The end of the fastening bolt located inside the outer sleeve contacts the outer circular surface of the guide rod.

[0040] The arc-shaped slide 3 is coaxial with the support plate 1 . A locking bolt 10 passes through the arc-shaped slide 3 . One end of the locking bolt 10 located inside the arc-shaped slide 3 contacts the outer circumferential surface of the support plate 1 .

[0041] A specific application of this embodiment is: when in use, the device is installed on the hook, and the telescopic rods 4 and the weight connecting structure 5 installed at one end of the telescopic rods 4 are adjusted according to the weight to be lifted, so that the weight connecting structure 5 can be adsorbed on the lifted weight, so that the hook is above the required lifting position, and then use the fastening bolts and locking bolts 10 to lock the telescopic rods 4 and the arc-shaped slide 3, and the lower hook hangs the weight on the hook to avoid the hook hitting the lifted weight or the hook running off the track, thereby improving safety.
