Description

Technical Field

[0001] The embodiments disclosed herein belong to the field of hoisting equipment technology, specifically relating to a hoisting device. Background Technology

[0002] To improve the efficiency of steel structure installation, lifting lugs need to be installed when steel structure components are processed in the factory. While lifting lugs facilitate hoisting, they also bring many problems. First, they increase the manufacturing cost in the factory. Second, the presence of lifting lugs reduces the loading rate of steel components during transportation. Third, after the steel components are installed on site, the lifting lugs need to be removed, which increases labor and machinery costs. Moreover, the removal of lifting lugs is mostly high-altitude work, which poses a significant safety risk. Utility Model Content

[0003] The embodiments disclosed herein are intended to at least address one of the technical problems existing in the prior art, and to provide a hoisting device.

[0004] Embodiments of this disclosure provide a hoisting device, the hoisting device comprising:

[0005] A clamping assembly, comprising at least three clamping elements forming an adjustable clamping space for accommodating a hoisted object, the clamping assembly being used to clamp the hoisted object;

[0006] A support assembly comprising at least two support members, the support assembly having a supported state and a relaxed state, wherein when the support assembly is in the supported state, a portion of the support assembly is located above the clamping space, and the support assembly is used to suspend the object being lifted; when the support assembly is in the relaxed state, the support assembly is located around the periphery of the clamping space.

[0007] In some embodiments of this disclosure, at least three of the clamping members are connected end-to-end to form an adjustable clamping space.

[0008] In some embodiments of this disclosure, the clamping assembly includes four clamping members connected end-to-end to form the clamping space.

[0009] In some embodiments of this disclosure, the first end of the clamping member is provided with a first connecting portion, the second end of the clamping member is provided with a second connecting portion, and two adjacent clamping members are connected to each other through the first connecting portion and the second connecting portion. The first connecting portion has at least two connection positions, and / or the second connecting portion has at least two connection positions.

[0010] In some embodiments of this disclosure, the first connecting portion includes a plurality of first connecting holes, the second connecting portion includes a second connecting hole, and the first connecting hole and the second connecting hole are connected by bolts.

[0011] In some embodiments of this disclosure, the clamping member includes a rod and a bent portion, the rod being connected to the bent portion, a first end of the rod being provided with the first connecting portion, and the bent portion being provided with the first connecting portion.

[0012] In some embodiments of this disclosure, at least two of the support members are rotatably connected to the clamping assembly. When the support assembly is in a supported state, the support members are located above the clamping space and are used to limit the position of the hoisted object. When the support assembly is in a relaxed state, the support members are located around the periphery of the clamping space.

[0013] In some embodiments of this disclosure, the support assembly includes two support members, which are respectively disposed on opposite sides of the clamping assembly.

[0016] The lifting device of this disclosure first places the support assembly of the lifting device in a relaxed state to prevent the support assembly from affecting the installation of the object to be lifted. The clamping space of the clamping assembly of the lifting device is then adjusted so that the size of the clamping space is larger than the size of the object to be lifted, i.e., the clamping space can accommodate the object. Then, the clamping assembly of the object is fitted onto the object, i.e., part of the object is accommodated within the clamping space. The clamping assembly is then adjusted to reduce the size of the clamping space, ensuring that the clamping assembly tightly clamps the object. Next, the support assembly is rotated from the relaxed state to the supported state. Finally, the support assembly is lifted using a hook or lifting rope, and the object to be lifted is lifted along with the support assembly. This lifting device, through the clamping assembly, can limit the movement of the object to be lifted, and through the support assembly, can lift the object, thereby achieving the lifting of the object. This lifting device eliminates the need to install and disassemble lifting lugs, saving lifting time, improving lifting efficiency, and reducing the safety risks of high-altitude operations.

[0027] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0028] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0029] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0030] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0031] like Figures 1 to 5 As shown, an embodiment of this disclosure provides a hoisting device 100, which includes: a clamping assembly 10 having an adjustable clamping space 101 for accommodating a hoisting object 200, and the clamping assembly 10 for clamping the hoisting object 200; and a support assembly 20 rotatably connected to the clamping assembly 10, having a supported state and a relaxed state. When the support assembly 20 is in the supported state, it is used to hoist the hoisting object 200; when the support assembly 20 is in the relaxed state, it is used to lift the hoisting object 200.

[0032] According to the hoisting device 100 of this disclosure, firstly, the support component 20 of the hoisting device 100 is placed in a relaxed state to avoid the support component 20 affecting the installation of the hoisted object 200. The clamping space 101 of the clamping component 10 of the hoisting device 100 is adjusted so that the size of the clamping space 101 is larger than the size of the hoisted object 200, that is, the clamping space 101 can accommodate the hoisted object 200. Then, the clamping component 10 of the hoisted object 200 is fitted onto the hoisted object 200, that is, part of the hoisted object 200 is accommodated in the clamping space 101. The clamping component 10 is adjusted to reduce the size of the clamping space 101 to ensure that the clamping component 10 clamps the hoisted object 200. Then, the support component 20 is rotated from the relaxed state to the supported state. Finally, the support component 20 is hoisted by a hook or rope, and the hoisted object 200 is hoisted together with the support component 20. The lifting device 100 disclosed herein can limit the lifting object 200 by clamping component 10 and lift the lifting object 200 by supporting component 20, thereby realizing the lifting of the lifting object 200. The lifting device 100 does not require the installation and disassembly of lifting lugs, saving lifting time, improving lifting efficiency, and reducing the safety risks of high-altitude operations.

[0033] In some embodiments of this disclosure, the clamping assembly 10 includes at least three clamping members 11, which are connected end-to-end to form an adjustable, enclosed clamping space 101. Specifically, the three clamping members 11, connected end-to-end, form a triangular clamping space 101 to accommodate the object 200 with a triangular cross-section being hoisted, and to clamp the object 200 being hoisted. The number of clamping members 11 can also be four, five, six, seven, eight, nine, ten, or more, as long as they can form an adjustable clamping space 101. Those skilled in the art can set the number and size of the clamping members 11 according to the actual shape of the object 200 being hoisted.

[0034] Since the cross-section of the object 200 being hoisted is mostly rectangular, in order to accommodate most objects 200 being hoisted, the clamping assembly 10 is configured to consist of four clamping members 11. The four clamping members 11 are connected end to end to form an adjustable clamping space 101 with a quadrilateral cross-section, so as to accommodate the object 200 being hoisted with a rectangular cross-section. The object 200 is clamped along the four sides of the object 200 by the four clamping members 11, so as to limit the object 200 being hoisted in two directions, that is, to restrict the movement of the object 200 being hoisted in the two directions on the horizontal plane.

[0035] Furthermore, the first end of the clamping member 11 is provided with a first connecting portion 111, and the second end of the clamping member 11 is provided with a second connecting portion 112. Two adjacent clamping members 11 are connected through the first connecting portion 111 and the second connecting portion 112. Specifically, the first connecting portion 111 has at least two connecting positions, and the second connecting portion 112 can be connected to any connecting position of the first connecting portion 111 to achieve relative position adjustment of two adjacent clamping members 11; or the first connecting portion 111 has one connecting position, and the second connecting portion 112 has at least two connecting positions, and the first connecting portion 111 can be connected to any connecting position of the second connecting portion 112 to achieve relative position adjustment of two adjacent clamping members 11; or the first connecting portion 111 has at least two connecting positions, and the second connecting portion 112 has at least two connecting positions, and any connecting position of the first connecting portion 111 can be connected to any connecting position of the second connecting portion 112 to achieve relative position adjustment of two adjacent clamping members 11.

[0036] In some embodiments of this disclosure, the first connecting portion 111 includes a plurality of first connecting holes 1111, and the second connecting portion 112 includes a second connecting hole (not shown in the figure). The second connecting hole of the second connecting portion 112 can mate with any one of the first connecting holes 1111 of the first connecting holes 1111, and the connection between the first connecting portion 111 and the second connecting portion 112 is achieved by a bolt 12 passing through the first connecting hole 1111 of the first connecting portion 111 and the second connecting hole of the second connecting portion 112. When the first connecting portion 111 of the first clamping member 11 mates with the second connecting portion 112 of the second clamping member 11, the relative position of the first clamping member 11 and the second clamping member 11 can be adjusted by moving the position of the second connecting hole of the second clamping member 11 to mate with different first connecting holes 1111 of the first clamping member 11.

[0037] Specifically, multiple first connecting holes 1111 are arranged at the first end along the length 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 enclosed by the four clamping members 11.

[0038] When the cross-sectional dimension of the object 200 being hoisted is larger than the cross-sectional dimension of the clamping space 101, the second connecting hole of the clamping member 11 is moved toward the end of the first end of the adjacent clamping member 11 to increase the cross-sectional dimension of the clamping space 101, ensuring that the clamping space 101 can accommodate the object 200 being hoisted. When the object 200 being hoisted is accommodated in the clamping space 101, the second connecting hole of the clamping member 11 is moved toward the second end of the adjacent clamping member 11 to reduce the cross-sectional area of ​​the clamping space 101, so that the clamping assembly 10 can clamp the object 200 being hoisted. When the cross-sectional dimension of the object 200 being hoisted is smaller than the cross-sectional dimension of the clamping space 101, the object 200 being hoisted is placed in the clamping space 101, and the second connecting hole of the clamping member 11 is moved toward the second end of the adjacent clamping member 11 to reduce the cross-sectional area of ​​the clamping space 101, so that the clamping assembly 10 can clamp the object 200 being hoisted.

[0039] Furthermore, the clamping member 11 includes a rod 113 and a bent portion 114. The rod 113 is connected to the bent portion 114. The first end of the rod 113 is provided with a first connecting hole 1111, and the second end of the rod 113 is provided with the bent portion 114. The bent portion 114 is perpendicular to the rod 113 and is provided with a second connecting hole. By setting the bent portion 114 and the rod 113 in a perpendicular connection relationship, it can be ensured that the bent portion 114 of the clamping member 11 of the rectangular cross-section clamping assembly 10 can be tightly fitted with the rod 113 of the adjacent clamping member 11. That is, when two adjacent clamping members 11 are connected, the bent portion 114 and the rod 113 fit more closely, improving the reliability of the connection between the rod 113 of the clamping member 11 and the bent portion 114 of the adjacent clamping member 11.

[0040] In some embodiments of this disclosure, the support assembly 20 includes at least two support members 21, which are rotatably connected to the clamping assembly 10. When the support assembly 20 is in a supported state, the support members 21 are located in a first position, with a portion of the support members 21 positioned directly above the clamping space 101 and extending into the interior of the suspended object 200 to support it. When the support assembly 20 is in a relaxed state, the support members 21 are located in a second position, with the support members 21 positioned around the periphery of the clamping space 101, so that the clamping assembly 10 can be fitted onto the suspended object 200, or so that the suspended object 200 can be easily removed from the clamping space 101 of the clamping assembly 10.

[0041] In some embodiments of this disclosure, the support assembly 20 includes two support members 21, which are disposed opposite to the clamping members 11 of the clamping assembly 10. Specifically, the two support members 21 are respectively disposed 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 the supported state, both support members 21 are in a first position, and the two support members 21 respectively limit the lifting object 200 from opposite sides. At the same time, the two support members 21 can extend into the internal space of the lifting object 200 to support the lifting object 200. When the support assembly 20 is in the relaxed state, both support members 21 are in a second position, and the two support members 21 are respectively positioned above and below the clamping space 101 to facilitate the installation and removal of the lifting object 200.

[0042] In some embodiments of this 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 to enable the support plate 211 to switch between a first position and a second position. The second end of the support plate 211 is provided with a limiting part 2111 and a lifting part 2112. The limiting part 2111 is used to support the object 200 being lifted. The limiting parts 2111 of the two support plates 211 respectively limit the object 200 from opposite sides to restrict the object 200 from swaying during the lifting process. The limiting parts 2111 of the two support plates 211 respectively limit the object 200 from the middle of the object 200. The portion of the limiting part 2111 located in the middle of the object 200 supports the object 200 to lift it.

[0043] 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 on the outside of the hoisted object 200, limiting the hoisted object 200 from the side. The protrusion forms a right-angle notch structure at the second end of the support plate 211, which is the limiting part 2111. When the support plate 211 is in the first position, one side of the right-angle notch structure limits the side of the hoisted object 200, and the other side adjacent to the aforementioned side supports the hoisted object 200.

[0044] Furthermore, the lifting part 2112 is a lifting hole, which is located on the protrusion. The lifting device 100 can be lifted by passing a rope or other hook through the lifting hole. The lifting device 100 lifts the object 200, thereby realizing the lifting of the object 200.

[0045] In some embodiments of this disclosure, the support member 21 includes two support plates 211 and a connecting rod 212. The two support plates 211 are connected relative to each other at both ends of the connecting rod 212. The two support members 21 can provide greater support capacity to improve the overall support capacity of the hoisting device 100 and expand the applicability of the hoisting device 100. The connecting rod 212 connects the two support plates 211 to their respective ends, 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.

[0046] Furthermore, each support member 21 includes two connecting rods 212, which are spaced apart between the two support plates 211 to improve the connection reliability of the two support plates 211 and make the connection between the two support plates 211 more secure.

[0047] A second aspect of this disclosure provides a hoisting method, which is implemented according to the hoisting device 100 described in any of the above embodiments, the hoisting method comprising:

[0048] Place the support component 20 of the hoisting device 100 in a relaxed state, and adjust the size of the clamping space 101 of the clamping component 10 of the hoisting device 100 to be larger than the size of the object 200 being hoisted.

[0049] The clamping component 10 of the hoisting device 100 is fitted onto the hoisting object 200, reducing the clamping space 101 so that the clamping component 10 clamps the hoisting object 200.

[0050] Rotate the support component 20 from the relaxed state to the supported state;

[0051] The object 200 is lifted by the support component 20.

[0052] According to the hoisting method disclosed herein, firstly, the support component 20 of the hoisting device 100 is placed in a relaxed state to avoid the support component 20 affecting the installation of the hoisted object 200. The clamping space 101 of the clamping component 10 of the hoisting device 100 is adjusted so that the size of the clamping space 101 is larger than the size of the hoisted object 200, that is, the clamping space 101 can accommodate the hoisted object 200. Then, the clamping component 10 of the hoisted object 200 is fitted onto the hoisted object 200, that is, part of the hoisted object 200 is accommodated in the clamping space 101. The clamping component 10 is adjusted to reduce the size of the clamping space 101 to ensure that the clamping component 10 clamps the hoisted object 200. Then, the support component 20 is rotated from the relaxed state to the supported state. Finally, the support component 20 is hoisted by a hook or hoisting rope, and the hoisted object 200 is hoisted together with the support component 20. The hoisting method disclosed herein can limit the hoisting object 200 by using the clamping component 10 of the hoisting device 100, and can lift the hoisting object 200 by using the support component 20 of the hoisting device 100, thereby realizing the hoisting of the hoisting object 200. This hoisting method eliminates the need to install and disassemble the lifting lugs, saves hoisting time, improves hoisting efficiency, and reduces the safety risks of high-altitude operations.

[0053] It is understood that the above embodiments are merely exemplary embodiments used to illustrate the principles of this disclosure, and this disclosure is not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and substance of this disclosure, and these modifications and improvements are also considered to be within the scope of protection of this disclosure.
