[0023] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided so that the present disclosure can be more thoroughly understood and the scope of the present disclosure can be fully conveyed to those skilled in the art. It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the drawings and in conjunction with the embodiments.

[0024] Embodiment of the steel structure sling:

[0025] Refer to Figures 1 to 5 , which shows the preferred structure of the steel structure sling in this embodiment. As shown in the figure, the steel structure sling includes: a main body 1, two hoisting members 2, and two strengthening mechanisms. Among them, the two hoisting members 2 are respectively arranged on opposite sides of the main body 1. Specifically, the main body 1 can be a plate-shaped body, and the two hoisting members 2 respectively correspond to two opposite plate surfaces of the main body 1.

[0026] Each lifting member 2 is used to be connected to the connecting body 3 in a position-adjustable manner. Specifically, the lifting member 2 is connected to the connecting body 3 to increase the length of the lifting member 2. The position between each lifting member 2 and the connecting body 3 is adjustable, so that the length can be accurately and finely adjusted without replacing the length of the connecting body 3.

[0027] When the steel structure sling is applied to lift the piece to be lifted, multiple steel structure slings and multiple connecting bodies 3 can be set. A connecting body 3 is arranged between every two adjacent steel structure slings. Then, both ends of the connecting body 3 are respectively connected to the corresponding lifting members 2 in the two steel structure slings in a position-adjustable manner. In this way, the overall length can be freely adjusted, so as to adapt to the pieces to be lifted in various length ranges.

[0028] There can be many implementation manners for the structure of the position adjustment between the lifting member 2 and the connecting body 3. Only one of them is introduced in this embodiment, but it is not limited to this structure: Each lifting member 2 is provided with an insertion channel 22. The connecting body 3 is movably inserted into the insertion channel 22. After the connecting body 3 is inserted into the insertion channel 22 to a certain depth, the connecting body 3 and the lifting member 2 are fastened by a fastener. Specifically, the cross-sectional shape of the insertion channel 22 matches the shape of the connecting body 3. Each lifting member 2 has an open end, which is the opening of the insertion channel 22. The connecting body 3 is inserted into the insertion channel 22 from the open end of the lifting member 2. The connecting body 3 can move in the insertion channel 22, and the depth of the connecting body 3 inserted into the insertion channel 22 is adjusted according to the actual situation. After adjustment, the connecting body 3 and the lifting member 2 are fastened together by a fastener.

[0029] Preferably, each fastener includes: a fastening bolt and a fastening nut. Among them, at least two through holes 21 penetrating the insertion channel 22 are provided along the length direction of each lifting member 2 ( Figure 1 the direction from left to right as shown). The connecting body 3 is provided with a through hole 31. The fastening bolt penetrates through any one of the through holes 21 and the through hole 31 and is screwed with the fastening nut. Specifically, each through hole 21 penetrates the width direction of the lifting member 2 ( Figure 2 the direction from left to right as shown) and penetrates the insertion channel 22. The connecting body 3 is placed in the insertion channel 22. The through hole 31 on the connecting body 3 corresponds to any one of the through holes 21. The fastening bolt penetrates through the corresponding through hole 21 and the through hole 31 and is screwed with the fastening nut, then the lifting member 2 and the connecting body 3 can be fixed together. Preferably, the through holes 21 are evenly distributed along the length direction of the lifting member 2.

[0030] During specific implementation, each lifting member 2 can be a square steel, the main body 1 can be a steel plate, and each connecting body 3 can be a square steel.

[0031] A strengthening mechanism is provided at the connection between the main body 1 and each lifting member 2, and this strengthening mechanism is used to improve the strength between the main body 1 and the corresponding lifting member 2.

[0032] It can be seen that in this embodiment, the two lifting members 2 are both connected to the connecting body 3, which can effectively extend the length. Moreover, the position between each lifting member 2 and the connecting body 3 is adjustable, and the length can be accurately and finely adjusted. When the lifting tool is applied to lift the to-be-lifted item, the lifting member 2 cooperates with the connecting body 3. According to the length of the to-be-lifted item, an appropriate number of lifting tools are selected to be assembled with the connecting body 3, which can be applicable to to-be-lifted items with various different length ranges, expanding the applicable range. There is no need to remanufacture, only assembly is required, which is simple and convenient, and can also be reused, avoiding waste and saving costs, solving the problem that the applicable range of the existing lifting tool is limited. The setting of the strengthening mechanism can effectively improve the strength between the main body 1 and the two lifting members 2, that is, improve the overall strength and stability of the steel structure lifting tool, and avoid deformation of the steel structure lifting tool.

[0033] See Figures 1 to 4 , in the above embodiment, each strengthening mechanism includes: two strengthening members 4. Among them, the two strengthening members 4 are respectively arranged on the first side ( Figure 1 the upper side shown) and the second side ( Figure 1 the lower side shown) opposite to the lifting member 2, and each strengthening member 4 is placed at the connection between the lifting member 2 and the main body 1. Specifically, each lifting member 2 can be in the shape of a cuboid, the first side and the second side are arranged oppositely and are two opposite side surfaces of the lifting member 2. The first sides of the two lifting members 2 correspond to each other, and the second sides also correspond to each other.

[0034] Each strengthening member 4 can include: two reinforcing ribs 41. Among them, the two reinforcing ribs 41 are arranged in parallel, and there is a preset distance between the two reinforcing ribs 41. This preset distance can be determined according to the actual situation, and this embodiment does not make any restrictions on this. Each reinforcing rib 41 can be in the shape of a right triangle.

[0035] In specific implementation, each strengthening mechanism includes: four reinforcing ribs 41. Two reinforcing ribs 41 are arranged in parallel on the first side of each lifting member 2, and two reinforcing ribs 41 are arranged in parallel on the second side of each lifting member 2. In this way, there are a total of eight reinforcing ribs 41.

[0036] See Figure 1, a preferred structure of the body structure is shown in the figure. As shown in the figure, the shape of the body 1 matches the cross-sectional shape of each lifting member 2, so the size of the body 1 matches the size of each lifting member 2. The two reinforcing members 4 on the same side of the two lifting members 2 are closely connected. Specifically, at the first side of the two lifting members 2, the two reinforcing rib plates 41 on one of the lifting members 2 are closely connected to the two reinforcing rib plates 41 on the other lifting member 2. Since each reinforcing rib plate 41 is a right triangle, one of the right-angled sides of each reinforcing rib plate 41 is connected to the corresponding lifting member 2, and the other right-angled side of each reinforcing rib plate 41 is connected to the other right-angled side of the corresponding reinforcing rib plate 41. At the second side of the two lifting members 2, the two reinforcing rib plates 41 on one of the lifting members 2 are closely connected to the two reinforcing rib plates 41 on the other lifting member 2.

[0037] It can be seen that in this embodiment, the two reinforcing members 4 on the same side of the two lifting members 2 are closely connected, which can effectively ensure the stable connection between the reinforcing members 4, and thus improve the strength between the body 1 and the two lifting members 2.

[0038] See Figure 3 , another preferred structure of the body structure is shown in the figure. As shown in the figure, the shape of the body 1 matches the cross-sectional shape of each lifting member 2, so the size of the body 1 matches the size of each lifting member 2. Extension plates 5 extending outward are provided at the first side and the second side of the body 1 corresponding to the lifting member 2, that is, the positions of the two extension plates 5 correspond to the positions of the first side and the second side of the lifting member 2 respectively. Each extension plate 5 is used to install a buckle 6, and the buckle 6 is used to be connected to the piece to be lifted or the hoist by a steel wire rope 7. Preferably, the body 1 and the two extension plates 5 are integrally formed.

[0039] During specific implementation, each extension plate 5 is provided with an installation opening 51, and each installation opening 51 is connected to a buckle 6.

[0040] Each reinforcing member 4 is arranged between the extension plate 5 and the corresponding lifting member 2. Specifically, the two reinforcing rib plates 41 in each reinforcing member 4 are placed between the extension plate 5 and the corresponding lifting member 2. More specifically, one of the right-angled sides of each reinforcing rib plate 41 is connected to the extension plate 5, and the other right-angled side of each reinforcing rib plate 41 is connected to the corresponding lifting member 2.

[0041] It can be seen that in this embodiment, by providing two extension plates 5 on the body 1, the length of the body 1 is extended, which is convenient for installing the buckle 6, and thus it is convenient for the buckle 6 to be connected to the piece to be lifted or the hoist by the steel wire rope 7. The structure is simple and easy to implement.

[0042] In summary, in this embodiment, both of the two lifting members 2 are connected to the connecting body 3, which can effectively extend the length. Moreover, the position between each lifting member 2 and the connecting body 3 is adjustable, enabling precise and delicate adjustment of the length. When the lifting tool is applied to lift the piece to be lifted, the lifting member 2 and the connecting body 3 cooperate with each other. According to the length of the piece to be lifted, an appropriate number of lifting tools are selected to be assembled with the connecting body 3, which can be applicable to pieces to be lifted with various different length ranges, expanding the applicable range. There is no need to remanufacture, only assembly is required, which is simple and convenient. It can also be reused, avoiding waste and saving costs. The setting of the strengthening mechanism can effectively improve the strength between the main body 1 and the two lifting members 2, that is, improve the overall strength and stability of the steel structure lifting tool, and avoid deformation of the steel structure lifting tool.

[0043] Embodiment of the steel structure lifting device:

[0044] This embodiment also proposes a steel structure lifting device. Refer to Figure 6 , the steel structure lifting device includes: a plurality of any one of the above steel structure lifting tools, a plurality of connecting bodies 3, and a plurality of buckles 6. Among them, a connecting body 3 is interposed between any two adjacent steel structure lifting tools. Each end of each connecting body 3 is connected to the corresponding lifting member 2 at the corresponding position in the corresponding steel structure lifting tool in a position-adjustable manner. That is to say, the two ends of the two connecting bodies 3 are respectively connected to the corresponding lifting members 2 in the two adjacent steel structure lifting tools in a position-adjustable manner.

[0045] Each buckle 6 is arranged on the main body 1 of the plurality of steel structure lifting tools at intervals. Specifically, among the plurality of steel bar lifting tools, several steel structure lifting tools' main bodies 1 can be selected to set the buckles 6 according to the actual situation. Preferably, refer to Figure 4 and Figure 6 , in the steel structure lifting tool provided with the buckle 6, extension plates 5 extending outward are arranged on both opposite sides of the main body 1. Each extension plate 5 is provided with an installation opening 51, and each installation opening 51 is connected to a buckle 6. Preferably, the main body 1 and the two extension plates 5 are integrally formed.

[0046] Among them, the specific implementation process of the steel structure lifting tool can refer to the above description, and this embodiment will not be elaborated here.

[0047] During specific implementation, when the steel structure hoisting device hoists a component to be hoisted, the length of the hoisting device is determined according to the length of the component to be hoisted. Then, an appropriate number of steel structure slings, connecting bodies 3, and buckles 6 are selected. Next, the steel structure slings and the connecting bodies 3 are assembled. Among them, two extension plates 5 are provided on the body 1 of the steel structure sling at the position where the buckle 6 needs to be set, and one buckle 6 is provided on each extension plate 5. In one steel structure sling, one of the buckles 6 is connected to the hoisting device through a steel wire rope 7, and the other buckle 6 is connected to the component to be hoisted through a steel wire rope 7. Buckles 6 are provided on the two outermost steel structure slings in the hoisting device, and an appropriate number of steel structure slings are selected according to the actual situation to set buckles 6 in the middle steel structure slings.

[0048] During specific implementation, half of the length of the component to be hoisted is used as the length of the hoisting device.

[0049] During specific implementation, each connecting body 3 can be a square steel, and the wall thickness of the square steel can be 8 mm. The length of each connecting body 3 can be determined according to the actual situation, and this implementation does not impose any restrictions on this. In this embodiment, the lengths of the connecting bodies 3 can be 2 meters, 3 meters, and 5 meters.

[0050] It can be seen that in this embodiment, multiple connecting bodies 3 are assembled with multiple steel structure slings to adapt to components to be hoisted with various different length ranges, expanding the scope of application. There is no need to remanufacture, and only assembly is required, which is simple and convenient. Moreover, each connecting body 3 is connected to the hoisting member 2 in the corresponding steel structure sling in an adjustable position, enabling fine adjustment of the overall length of the hoisting device. Additionally, the setting of the buckle 6 can connect the component to be hoisted and the hoisting machine together, facilitating hoisting.
