Description

Technical Field

[0001] The utility model relates to the field of crane hooks, in particular to a crane hook mechanism. Background Art

[0002] Cranes usually use hook mechanisms to lift and suspend cargo. The hook mechanism is a very important component of a crane. It can bear and lift the weight of cargo and ensure safe and efficient operation through various mechanical means. Crane operators can accurately control the rise, fall, movement and stop of the hook through the control system. Cranes are usually equipped with electronic control systems to make operations more precise and safe. The design and selection of the hook mechanism depends on the type of crane, load requirements and specific working environment. Cranes are usually equipped with more powerful and durable hook mechanisms to meet heavy lifting needs in industry and construction.

[0003] In the actual use of crane hooks, ordinary hooks can only lift goods, but the anti-falling mechanism has a relatively simple structure and insufficient stability. It is easy to fall off during actual use, which reduces safety. It is also inconvenient to take goods, and it is impossible to monitor the goods in real time during the lifting process, and it is impossible to understand the status of the goods, which is inconvenient for operators to use.

Then the camera 22 can be connected to a mobile phone or other devices through wireless technology, so that the operator can monitor the cargo in real time during the hoisting process, thereby improving the safety of the crane body 28 during hoisting. In winter, when the camera 22 is fogged, the hot air blower 2 can be started. The hot air blower 2 is also waterproof, so that the hot air can be blown to the camera 22 through the mounting tube 21, so that on the one hand, the camera 22 can be defogged so that the camera 22 can shoot and record normally, and on the other hand, it can also prevent the camera 22 from malfunctioning in the cold winter.

[0028] Reference Figure 1-Figure 4 In a preferred embodiment, threaded holes are provided inside the fixing plate 16 and the mounting groove 24, and the threaded rod 19 is arranged inside the threaded holes.

The camera 22 and the hot air blower 2 are both waterproof.

[0029] Specifically, the working process or working principle of the crane hook mechanism is as follows: in the specific use of the crane hook, the usual hook can only lift the cargo, but the anti-falling mechanism has a relatively simple structure and insufficient stability, and is prone to falling off during specific use, thereby reducing safety, and is inconvenient when taking the cargo, and it is impossible to monitor the cargo in real time during the lifting process, and it is impossible to understand the status of the cargo, which is inconvenient for the operator to use. Therefore, this technical solution can solve the above problems. When the operator needs to lift the cargo, the operator can first lift the cable of the cargo. The operator puts the hook body 13 into the hook body 13, then pulls the mounting ring 23 to drive the tension spring 18 and the insertion rod 17 to move, and then rotates the assembly plate 29. At this time, the spring 15 produces elasticity. Then, when the assembly plate 29 is rotated to the inside of the mounting groove 24, the operator can release his hand at this time, and the insertion rod 17 can be inserted into the inside of the insertion hole 25. The operator can use the threaded rod 19 to limit the fixing plate 16 and the hook body 13 to complete the limit of the cable in the hook body 13. Finally, the crane body 28 is started to hoist the cargo, thereby preventing the hook body 13 from falling off and improving the hook body 13. Safety, when the cable needs to be taken out, the threaded rod 19 can be taken out to release the limit of the hook body, then the installation ring 23 is pulled to make the plug rod 17 to release the limit of the plug rod 17, and then the assembly plate 29 is rotated. At this time, under the elastic action of the spring 15, the rotating plate can be moved away from the hook body 13. Finally, the operator can take out the cable and take the goods. When the operator needs to monitor the hook body 13 during the lifting of the goods, the operator can monitor the goods through the camera 22, and the camera 22 is waterproof. Then the camera 22 can be By connecting a mobile phone or other device through wireless technology, the operator can monitor the cargo in real time during the lifting process, thereby improving the safety of the crane body 28 during lifting. In winter, when the camera 22 is fogged, the hot air blower 2 can be started. The hot air blower 2 is also waterproof, so that the hot air can be blown to the camera 22 through the mounting pipe 21. On the one hand, the camera 22 can be defogged so that the camera 22 can shoot and record normally. On the other hand, it can also prevent the camera 22 from malfunctioning in the cold winter, making it easier for the operator to use it. At this point, all processes are completed.

[0030] It should be noted that the hot air blower 2, the crane body 28 and the camera 22 are all electrically connected to an external power supply and are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
