Description

Technical Field

[0001] This utility model belongs to the technical field of auxiliary lifting tools in hoisting equipment, specifically relating to a pre-set lifting tool for steel pipe stacks based on a swing-type mechanism. Background Technology

[0002] Currently, lifting slings are connecting devices used in lifting equipment to lift heavy objects. Steel pipe manufacturers need to lift bundles of steel pipes from stacks. Due to the large number and size of the bundles, lifting them presents a certain degree of difficulty. A common method is to use a hook and sling. First, the sling is passed through the bottom of the bundle, and then both ends of the sling are hooked onto the hook, thus lifting the steel pipes smoothly to the designated location. However, because the position of the sling is not fixed, this method has two problems: First, if the center of gravity is not accurately located, the bundle of steel pipes is prone to tilting, making it easy for them to collide with surrounding objects during transport, and posing a safety hazard of slipping. Second, if the sling's placement deviates, hooking it becomes difficult, and readjusting the sling's position is not only laborious but also extremely time-consuming, reducing lifting efficiency.

[0003] Patent document CN204125015 U discloses a steel pipe stack lifting device, which mainly includes a lifting beam, chain, lifting ring, hook, rubber-coated sling, chain adjuster, butterfly buckle, and pin. The pin inserts into the opening of the steel pipe to form a lifting point. Therefore, this device can prevent tilting during the lifting and transportation of the steel pipe stack, as well as large swings and twists. However, this device does not pre-set the placement position of the lifting device. Patent document CN 111661752 A discloses a heavy-duty automatic telescopic rotating lifting device for steel pipes, which mainly includes a main beam, hydraulic cylinder, distribution box, multi-way valve, gear plate, motor, main shaft, connector, hanger, pad, sub-beam, hook, positioning clamp, universal ball, and positioning plate. Because the centerline of the main beam is parallel to the centerline of the steel pipe, and the hooks are located at both ends of the steel pipe, the hydraulic rotating device can adjust the spacing between the hooks to accommodate steel pipes of different lengths. However, this device does not pre-set the placement position of the lifting device. Patent document CN 214611099 U discloses a steel pipe lifting attachment, which mainly includes a lifting chain, a lifting body, a top frame, outriggers, a rod, a star wheel, fins, a shaft, a ratchet, a pawl, and a stop pin. Due to the unidirectional rotation of the star wheel, the fins will prevent the steel pipe from rolling down. Moving the pawl can both unload the steel pipe individually and avoid collisions between the steel pipes. However, the device does not preset the placement position of the lifting attachment.

Then, the four bearing segments 403 of the other four second brackets 4 are inserted into the four rolling bearings 10. In this way, the two fourth brackets 6, the four rolling bearings 10 and the other four second brackets 4 can be assembled.

[0055] Then, the two fourth brackets 6 are simultaneously placed on the base plate 2, and the sixteen eighth through holes 605 of the two fourth brackets 6 are aligned with the sixteen fourth through holes 201 of the base plate 2. Then, sixteen screws 11 are inserted into the sixteen sets of aligned through holes, and sixteen nuts 12 are screwed onto the threaded ends of the sixteen screws 11.

In this way, the entire device is assembled and can be put into use.

[0059] The principle for setting the swing direction of the second support of the pre-set lifting device for a swing-type steel pipe stack provided by this utility model.

[0060] like Figure 3 and Figure 6 As shown in the top view of the device of this utility model, for ease of description, the eight second supports 4 can be defined as ①, ②, ③, ④, ⑤, ⑥, ⑦ and ⑧, wherein the sixteen bearing segments 403 of the eight second supports 4 are all swing shafts;

[0061] like Figure 3 As shown, assuming that initially all eight second supports 4 are positioned front and back, the simplified version is as follows: Figure 23 As shown, ①, ④, ⑤ and ⑧ simultaneously rotate 90 degrees clockwise, and ②, ③, ⑥ and ⑦ simultaneously rotate 90 degrees counterclockwise. Thus, all eight second supports 4 are positioned to the left and right. We can define this rotation direction of the second supports 4 as positive.

[0062] like Figure 6 As shown, assuming that initially all eight second supports 4 are positioned on the left and right, after simplification as follows: Figure 24As shown, ①, ④, ⑤ and ⑧ simultaneously rotate 90 degrees counterclockwise, and ②, ③, ⑥ and ⑦ simultaneously rotate 90 degrees clockwise. Thus, all eight second supports 4 are arranged in a front-to-back configuration. We can define this rotation direction of the second supports 4 as reverse.

[0063] The present invention provides a method for using a pre-set lifting device for steel pipe stacks based on a gyratory type.

[0064] Combination Figures 1 to 22 As shown, assuming that initially all eight second supports 4 are positioned left and right, and the four sixth bodies 801 of the four sixth supports 8 are inserted into the eight through slots 404 of the eight second supports 4, firstly, two lifting straps are passed through the bottom of the bundled steel pipes located within the steel pipe stack, and then the two ends of the two lifting straps are respectively inserted into the fourteenth through holes 805 of the four sixth supports 8. At this time, the four sixth supports 8 can be directly aligned with the four hooks of the crane. Then, the four hooks are respectively inserted into the four thirteenth through holes 804 of the four sixth supports 8. Then, the eight second supports 4 are rotated in the opposite direction so that all eight second supports 4 are positioned front and back. At this time, the four sixth bodies 801 of the four sixth supports 8 can be pulled out from the eight through slots 404 of the eight second supports 4. In this way, the crane can lift the four sixth supports 8 without obstruction.

[0065] Additional explanation: The pre-installed lifting device for steel pipe stacks based on the gyratory type provided by this utility model adopts a symmetrical structure design. First, according to the interval between the four hooks of the crane, the setting width and setting height of the steel pipe stack, multiple specifications of this utility model device should be designed and manufactured to match it.
