[0036] According to the lifting device 100 disclosed in the present invention, first, the support component 20 of the lifting device 100 is placed in a relaxed state to prevent the support component 20 from affecting the installation of the lifting object 200, and the clamping space 101 of the clamping component 10 of the lifting device 100 is adjusted so that the size of the clamping space 101 is larger than the size of the lifting object 200, that is, the clamping space 101 can accommodate the lifting object 200, and then, the clamping component 10 of the lifting object 200 is sleeved on the lifting object 200, that is, part of the lifting object 200 is accommodated in the clamping space 101, and the clamping component 10 is adjusted to reduce the size of the clamping space 101 to ensure that the clamping component 10 clamps the lifting object 200, and then the support component 20 is rotated from the relaxed state to the supporting state, and finally the support component 20 is lifted by a hook or a lifting rope, and the lifting object 200 is lifted together with the support component 20. The hoisting device 100 disclosed in the present invention can limit the hoisting object 200 through the clamping component 10, and can lift the hoisting object 200 through the supporting component 20, thereby realizing the hoisting of the hoisting object 200. The hoisting device 100 does not need to install and disassemble the lifting ears, thus saving hoisting time, improving hoisting efficiency, and reducing the safety risks of high-altitude operations.

[0037] In some embodiments of the present disclosure, the clamping assembly 10 includes at least three clamping members 11, and the at least three clamping members 11 are connected end to end to form an adjustable closed accommodation space. Specifically, the three clamping members 11 are connected end to end to form a triangular accommodation space to accommodate the hoisted object 200 with a triangular cross-section, and the hoisted object 200 is clamped by the three clamping members 11. The number of the clamping members 11 can also be four, five, six, seven, eight, nine, ten or more, as long as they can form an adjustable accommodation space. Those skilled in the art can set the number and size of the clamping members 11 according to the actual shape of the hoisted object 200. Since the cross-section of the hoisted object 200 is mostly rectangular, in order to accommodate most of the hoisted objects 200, the clamping assembly 10 is configured to be composed of four clamping members 11. The four clamping members 11 are connected end to end to form an adjustable accommodating space with a quadrilateral cross-section to accommodate the hoisted object 200 with a rectangular cross-section. The hoisted object 200 is clamped along the four faces of the hoisted object 200 by the four clamping members 11 to limit the hoisted object 200 in two directions, that is, to limit the movement of the hoisted object 200 in the two directions where the horizontal plane is located.

[0038] Further, a first connection portion 111 is provided at the first end of the clamping member 11, and a second connection portion 112 is provided at the second end of the clamping member 11, and two adjacent clamping members 11 are connected to the second connection portion 112 via the first connection portion 111. Specifically, the first connection portion 111 has at least two connection positions, and the second connection portion 112 can be connected to any connection position of the first connection portion 111 to achieve relative position adjustment of two adjacent clamping members 11; or the first connection portion 111 has one connection position, and the second connection portion 112 has at least two connection positions, and the first connection portion 111 can be connected to any connection position of the second connection portion 112 to achieve relative position adjustment of two adjacent clamping members 11; or the first connection portion 111 has at least two connection positions, and the second connection portion 112 has at least two connection positions, and any connection position of the first connection portion 111 can be connected to any connection position of the second connection portion 112 to achieve relative position adjustment of two adjacent clamping members 11.

[0039] In some embodiments of the present disclosure, the first connection portion 111 includes a plurality of first connection holes 1111, and the second connection portion 112 includes a second connection hole (not shown in the figure). The second connection hole of the second connection portion 112 can be matched with any first connection hole 1111 of the first connection hole 1111, and the connection between the first connection portion 111 and the second connection hole of the second connection portion 112 is achieved by passing the bolt 12 through the first connection hole 1111 of the first connection portion 111 and the second connection hole of the second connection portion 112. When the first connection portion 111 of the first clamping member 11 is matched with the second connection portion 112 of the second clamping member 11, the second connection hole of the second clamping member 11 is moved to match with different first connection holes 1111 of the first clamping member 11, so as to adjust the relative position of the first clamping member 11 and the second clamping member 11.

[0040] Specifically, a plurality of first connecting holes 1111 are arranged at the first end along the length direction of the clamping member 11. By cooperating with the second connecting holes of adjacent clamping members 11 and the first connecting holes 1111 at different positions, the relative positions of two adjacent clamping members 11 can be adjusted, thereby achieving the purpose of adjusting the size of the clamping space 101 surrounded by the four clamping members 11.

[0041] When the cross-sectional size of the hoisted object 200 is larger than the cross-sectional size of the clamping space 101, the second connecting hole of the clamping piece 11 is moved toward the end of the first end of the adjacent clamping piece 11 to increase the cross-sectional size of the clamping space 101, thereby ensuring that the clamping space 101 can accommodate the hoisted object 200; when the hoisted object 200 is accommodated in the clamping space 101, the second connecting hole of the clamping piece 11 is moved toward the second end of the adjacent clamping piece 11 to reduce the cross-sectional area of ​​the clamping space 101, thereby allowing the clamping assembly 10 to clamp the hoisted object 200; when the cross-sectional size of the hoisted object 200 is smaller than the cross-sectional size of the clamping space 101, the hoisted object 200 is placed in the clamping space 101, and the second connecting hole of the clamping piece 11 is moved toward the second end of the adjacent clamping piece 11 to reduce the cross-sectional area of ​​the clamping space 101, thereby allowing the clamping assembly 10 to clamp the hoisted object 200.

[0042] Furthermore, the clamping member 11 includes a rod body 113 and a bending portion 114, the rod body 113 is connected to the bending portion 114, a first connection hole 1111 is provided at the first end of the rod body 113, a bending portion 114 is provided at the second end of the rod body 113, the bending portion 114 is arranged perpendicular to the rod body 113, and a second connection hole is provided on the bending portion 114. By arranging the bending portion 114 and the rod body 113 in a perpendicular connection relationship, it can be ensured that the bending portion 114 of the clamping member 11 of the clamping assembly 10 with a rectangular cross-section can be closely attached to the rod body 113 of the adjacent clamping member 11, that is, when two adjacent clamping members 11 are connected, the bending portion 114 and the rod body 113 are more closely attached, thereby improving the reliability of the connection between the rod body 113 of the clamping member 11 and the bending portion 114 of the adjacent clamping member 11.

[0043] In some embodiments of the present disclosure, the support assembly 20 includes at least two support members 21, and at least two support members 21 are rotatably connected to the clamping assembly 10. When the support assembly 20 is in a supporting state, the support member 21 is located in a first position, a portion of the support member 21 is located directly above the clamping space 101, and the portion of the support member 21 extends into the interior of the hoisted object 200 to support the hoisted object 200; when the support assembly 20 is in a relaxed state, the support member 21 is located in a second position, and the support member 21 is located on the peripheral side of the clamping space 101, so that the clamping assembly 10 can be mounted on the hoisted object 200, or the hoisted object 200 can be easily removed from the clamping space 101 of the clamping assembly 10.

[0044] In some embodiments of the present disclosure, the support assembly 20 includes two support members 21, and the two support members 21 are arranged opposite to the clamping member 11 of the clamping device. Specifically, the two support members 21 are respectively arranged on two opposite clamping members 11, and each support member 21 is rotatably connected to the corresponding clamping member 11. When the support assembly 20 is in a supporting state, the two support members 21 are both in a first position, and the two support members 21 respectively limit the hoisting object 200 from the opposite sides of the hoisting object 200. At the same time, the two support members 21 can extend into the internal space of the hoisting object 200 to support the hoisting object 200. When the support assembly 20 is in a relaxed state, the two support members 21 are both in a second position, and the two support members 21 avoid the positions above and below the clamping space 101, respectively, so as to facilitate the installation and removal of the hoisting object 200.

[0045] In some embodiments of the present disclosure, the support member 21 includes: a support plate 211, the first end of the support plate 211 is rotatably connected to the clamping member 11 of the clamping assembly 10, so as to realize the conversion of the support plate 211 between the first position and the second position. The second end of the support plate 211 is provided with a limiting portion 2111 and a hoisting portion 2112, the limiting portion 2111 is used to support the hoisted object 200, the limiting portions 2111 of the two support plates 211 respectively limit the hoisted object 200 from the opposite sides of the hoisted object 200 to limit the hoisted object 200 from shaking during the hoisting process, and the limiting portions 2111 of the two support plates 211 respectively limit the hoisted object 200 from the middle of the hoisted object 200, and the partial limiting portion 2111 located in the middle of the hoisted object 200 plays a supporting role on the hoisted object 200 to lift the hoisted object 200.

[0046] Specifically, a protrusion is formed at the second end of the support plate 211. When the support plate 211 is in the first position, the protrusion is located outside the hoisted object 200, and limits the hoisted object 200 from the side of the hoisted object 200. The protrusion forms a right-angled notch structure at the second end of the support plate 211, and the right-angled notch structure is the limiting portion 2111. When the support plate 211 is in the first position, one side of the right-angled notch structure limits the side of the hoisted object 200, and the other side adjacent to the above side supports the hoisted object 200.

[0047] Furthermore, the hoisting portion 2112 is a hoisting hole, which is provided on the protrusion. The hoisting device 100 can be hoisted by passing a rope or other hook through the hoisting hole. The hoisting device 100 hoists the hoisting object 200, thereby realizing the hoisting of the hoisting object 200.

[0048] In some embodiments of the present disclosure, the support member 21 includes two support plates 211 and a connecting rod 212. The two support plates 211 are relatively connected to the two ends of the connecting rod 212. The two support members 21 can provide greater supporting capacity to improve the overall supporting capacity of the hoisting device 100 and improve the applicable scope of the hoisting device 100. The connecting rod 212 connects the two support plates 211 at both ends thereof, that is, the two support plates 211 are arranged at intervals through the connecting rod 212 to improve the stability of the support member 21 in supporting the hoisted object 200.

[0049] Furthermore, each support member 21 includes two connecting rods 212 , and the two connecting rods 212 are arranged between the two support plates 211 at intervals to improve the connection reliability of the two support plates 211 and make the connection between the two support plates 211 more firmly.

[0051] The supporting assembly 20 of the hoisting device 100 is placed in a relaxed state, and the size of the clamping space 101 of the clamping assembly 10 of the hoisting device 100 is adjusted to be larger than the size of the hoisting object 200;
