[0026] Example: A pipe installation lifting device, such as Figures 1-4 As shown, it includes a gantry crane 1, a lifting chain 2 and a hook 3 installed on the gantry crane 1, a load-bearing limit component 4 is provided at the connection between the lifting chain 2 and the hook 3, and an alarm component 5 is provided on the outside of the load-bearing limit component 4;

[0027] The load-bearing limiting component 4 includes a support cylinder 401 fixedly connected to the end of the lifting chain 2. A neodymium iron boron high-power permanent magnet 402 is installed on the inner wall of the upper end of the support cylinder 401. A low carbon steel magnetic block 403 is magnetically connected to the lower end of the neodymium iron boron high-power permanent magnet 402. A support connecting column 404 is installed at the lower end of the low carbon steel magnetic block 403.

[0028] The alarm component 5 includes a protective shell 508 fixedly installed on the outer surface of the support cylinder 401. A magnetic female head 504 is provided inside the protective shell 508. A magnetic male head 505 is provided below the magnetic female head 504. A warning chamber 506 is installed at the lower end of the magnetic male head 505. A warning light 507 is installed on one side of the warning chamber 506. Two connecting posts 502 are symmetrically arranged on the outside of the protective shell 508.

[0029] The outer diameter of the low-carbon steel magnetic block 403 is larger than the outer diameter of the support connecting column 404. The lower end of the support connecting column 404 is inserted into the outside of the support cylinder 401. Several limiting columns 405 are installed on the inner wall of the lower end of the support cylinder 401 in a circular and equidistant arrangement. The limiting columns 405 and the low-carbon steel magnetic block 403 are inserted into each other.

[0030] A spring 406 is sleeved on the outside of the limiting post 405. The upper end of the spring 406 is fixedly connected to the lower end of the low carbon steel magnetic block 403, and the lower end of the spring 406 is fixedly connected to the inner wall of the lower end of the support cylinder 401.

[0031] A limit ring 407 is installed on the inner wall of the lower end of the support cylinder 401. The outer diameter of the limit ring 407 is the same as the outer diameter of the low carbon steel magnetic block 403.

[0032] The lower end of the support connecting column 404 is fixedly connected to the hook 3. A connecting block 501 is installed on the outer surface of the lower half of the support connecting column 404. The lower ends of the two connecting columns 502 are fixedly connected to the connecting block 501.

[0033] The upper ends of the two connecting posts 502 are inserted into the protective shell 508, and the upper ends of the two connecting posts 502 are connected to the support block 503.

[0034] The magnetic female connector 504 is fixedly installed at the lower end of the support block 503, and the magnetic male connector 505 is located inside the magnetic female connector 504.

[0035] In existing gantry cranes, when lifting pipelines, the pipeline is secured with straps, and then the straps are hung on hooks 3. The lifting chain 2 then drives the hooks 3 and the pipeline to lift. This process is known technology. To prevent the pipeline weight from exceeding the maximum pulling force of the gantry crane 1 and causing safety hazards, a load-bearing limit component 4 and an alarm component 5 are installed at the connection between the lifting chain 2 and the hooks 3. Through the connection of neodymium iron boron (NdFeB) high-strength permanent magnet 402 and low-carbon steel magnetic block 403, the attraction between the NdFeB high-strength permanent magnet 402 and the low-carbon steel magnetic block 403 is made equal to the maximum pulling force of the gantry crane 1. This is also known technology and will not be elaborated further. When the pipeline weight exceeds the bearing capacity of the gantry crane 1, the pulling force of the hooks 3 on the supporting connecting column 404 is greater than that of the NdFeB high-strength permanent magnet 402. The attraction between the neodymium iron boron (NdFeB) high-strength permanent magnet 402 and the low-carbon steel magnetic block 403 is such that, since the NdFeB high-strength permanent magnet 402 cannot move, the supporting connecting column 404 will drive the low-carbon steel magnetic block 403 to move downwards, causing the low-carbon steel magnetic block 403 to detach from the NdFeB high-strength permanent magnet 402. During this process, to avoid the low-carbon steel magnetic block 403 moving too far and causing excessive impact, several springs 406 are set below the low-carbon steel magnetic block 403 to buffer the downward movement of the low-carbon steel magnetic block 403. The limiting column 405 limits the springs 406 to prevent the springs 406 from deviating. At the same time, the limiting ring 407 supports and limits the movement of the low-carbon steel magnetic block 403, reducing the downward distance and impact of the low-carbon steel magnetic block 403.

[0036] When the low-carbon steel magnetic block 403 separates from the neodymium iron boron strong permanent magnet 402, it indicates that the pipeline exceeds the bearing capacity of the gantry crane 1. To prompt the operator to stop operation, an alarm component 5 is installed on the outside of the support cylinder 401. When the support connecting column 404 moves down, the support connecting column 404 will drive the connecting block 501 and the connecting column 502 to move down synchronously. Since the length of the connecting column 502 is fixed, the connecting column 502 will drive the support block 503 and the magnetic female head 504 to move down synchronously. The magnetic female head 504 and the magnetic male head 505 will be magnetically connected. At this time, a complete circuit is formed between the warning cabin 506, the warning light 507, the magnetic male head 505, and the magnetic female head 504. This process is a known technology and will not be described in detail here. Then the warning light 507 will start to flash to remind the operator that the pipeline is overloaded. During this process, the protective shell 508 plays a protective role for its interior.

[0037] With the cooperation of the load-bearing limit component 4 and the alarm component 5, firstly, it can promptly issue a warning to the operator to avoid the situation of hoisting overweight pipelines; secondly, it can effectively reduce safety risks and further ensure safety during the lifting process.

[0038] Working principle: When the gantry crane 1 lifts the pipeline, if the weight of the pipeline exceeds the bearing capacity of the gantry crane 1, the pulling force of the hook 3 on the support connecting column 404 is greater than the attraction between the neodymium iron boron strong permanent magnet 402 and the low carbon steel magnetic block 403. The low carbon steel magnetic block 403 and the neodymium iron boron strong permanent magnet 402 are separated, and the support connecting column 404 will drive the low carbon steel magnetic block 403 to move downward. At this time, the support connecting column 404 will drive the connecting block 501 and the connecting column 502 to move downward synchronously. The connecting column 502 will drive the support block 503 and the magnetic female head 504 to move downward synchronously. The magnetic female head 504 and the magnetic male head 505 will be magnetically connected. At this time, a complete circuit is formed between the warning cabin 506, the warning light 507, the magnetic male head 505, and the magnetic female head 504. The warning light 507 will start to flash, reminding the operator that the pipeline is overloaded.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
