It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0030] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0031] It should be understood that the orientation or positional relationship indicated by terms such as "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings. It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the structure or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0032] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality of" means two or more, unless otherwise specifically defined.

[0033] During the process of assembling some large equipment, due to the relatively large size of some structural parts, it is usually necessary to use a lifting tool to lift the large structural parts and move them to the designated position for installation. For example, in the assembly process of a bending machine, a lifting tool is usually used to hoist the base frame of the bending machine to the designated position for assembly.

[0034] Currently, the common lifting tools on the market mainly include a lifting beam, a lifting rope connected to the lifting beam, and a lifting buckle connected to the end of the lifting rope. The lifting buckle is connected to the base frame of the bending machine, and then by lifting the lifting beam, the base frame of the bending machine is hoisted to the designated position. However, the length of this kind of lifting tool is too long, and it cannot be used for hoisting in some sites with limited height space. Moreover, when using this kind of lifting tool for hoisting, during the process of moving the base frame of the bending machine, the base frame of the bending machine shakes violently. On the one hand, it will result in low hoisting accuracy. On the other hand, the lifting rope is prone to breakage and the safety risk is relatively high.

[0035] To solve the above technical problems, the embodiments of this application provide a lifting assembly and a lifting system. In order to illustrate the technical solutions described in this application, the following will be described in detail in conjunction with specific drawings and embodiments.

[0036] The first embodiment

[0037] As Figures 1 to 3 shown, this embodiment provides a hoisting assembly 10, including a cross beam 100, at least two first shackles 210 and at least two second shackles 220. The number of the first shackles 210 is equal to that of the second shackles 220, and the first shackles 210 and the second shackles 220 are arranged in one-to-one correspondence. All the first shackles 210 are installed on the cross beam 100 at intervals. The first shackles 210 are detachably connected to the corresponding second shackles 220. Each second shackle 220 is used for detachably connecting to a piece to be hoisted 20. The cross beam 100 is used for directly or indirectly connecting to a hoisting device.

[0038] In the embodiment of the present application, the number of the first shackles 210 can be two, three or even more. As Figure 1 shown, when the number of the first shackles 210 is two, the number of the second shackles 220 is also two. The two second shackles 220 are respectively connected to different areas of the piece to be hoisted 20 to hoist the piece to be hoisted 20 smoothly. When the number of the first shackles 210 is greater than two, the number of the second shackles 220 is also greater than two. Optionally, any two or more of the second shackles 220 can be respectively connected to the piece to be hoisted 20. In this way, according to the size of the piece to be hoisted 20, two second shackles 220 with different intervals can be selected to be connected to the piece to be hoisted 20.

[0039] In the embodiment of the present application, the piece to be hoisted 20 can specifically be a base frame of a bending machine or any other structure to be hoisted. In some embodiments, the second shackle 220 and the piece to be hoisted 20 can be connected by a clamping method. Or, as Figure 2 and Figure 3 shown, the piece to be hoisted 20 can be provided with a through hole 21, and the second shackle 220 is passed through the through hole 21 to connect the second shackle 220 to the piece to be hoisted 20.

[0040] Compared with the related art, the hoisting assembly 10 provided by the embodiment of the present application installs the first shackles 210 on the cross beam 100, and connects the second shackles 220 connected to the first shackles 210, and then connects the second shackles 220 to the piece to be hoisted 20 to hoist the piece to be hoisted 20 only. In this way, not only can the total height of the hoisting assembly 10 be effectively reduced, so that the hoisting assembly 10 provided by the embodiment of the present application can also be applied to a site with limited height space; but also the swaying amplitude of the piece to be hoisted 20 during the moving process can be effectively reduced, which is beneficial to improving the safety performance and the hoisting accuracy.

[0041] In a possible design, as Figure 1As shown, a plurality of first connection holes 121 are spaced apart on the cross beam 100, and each first shackle 210 is inserted into different first connection holes 121. The number of first connection holes 121 is greater than the number of first shackles 210. In some alternative embodiments, the number of first shackles 210 is two, and the number of first connection holes 121 can be three, four, six or more, which is not uniquely limited herein. Specifically, the plurality of first connection holes 121 are specifically spaced apart along the length direction of the cross beam 100.

[0042] With such an arrangement, the distance between any two first shackles 210 can be adjusted by installing the first shackles 210 in different first connection holes 121, and further, the distance between the two second shackles 220 corresponding to the two adjusted first shackles 210 can be adjusted, so that the distance between the two adjusted second shackles 220 matches the size of the workpiece to be lifted 20.

[0043] In a possible design, as Figure 1 and Figure 4 shown, the first shackle 210 includes a main body 201 and a connecting member 202. The main body 201 is a semi-enclosed structure. The main body 201 has a first end 2011 and a second end 2012. Through holes are respectively provided in the first end 2011 and the second end 2012. Internal threads are provided on the inner wall of the through hole in the second end 2012. The connecting member 202 passes through the through hole in the first end 2011 and is threadedly connected to the through hole in the second end 2012. Alternatively, the second shackle 220 includes a main body 201 and a connecting member 202. The main body 201 is a semi-enclosed structure. The main body 201 has a first end 2011 and a second end 2012. Through holes are respectively provided in the first end 2011 and the second end 2012. Internal threads are provided on the inner wall of the through hole in the second end 2012. The connecting member 202 passes through the through hole in the first end 2011 and is threadedly connected to the through hole in the second end 2012. Or, both the first shackle 210 and the second shackle 220 include the above-mentioned main body 201 and connecting member 202.

[0044] Optionally, the main body 201 can specifically be a semi-enclosed structure in the shape of a "U", "C" or other structural shapes, which is not uniquely limited herein. For the convenience of description, the main body 201 and the connecting member 202 in the first shackle 210 will be referred to as the first main body and the first connecting member hereinafter, and the main body 201 and the connecting member 202 in the second shackle 220 will be referred to as the second main body and the second connecting member.

[0045] According to the above embodiments, when installing the first shackle 210, the first connecting member can be sequentially passed through the through hole of the first end 2011 of the first main body and the first connecting hole 121 on the cross beam 100, and then threadedly connected to the through hole of the second end 2012 of the first main body. When installing the second shackle 220, the second connecting member can be sequentially passed through the through hole of the first end 2011 of the second main body and the through hole 21 on the piece to be lifted 20, and then threadedly connected to the through hole of the second end 2012 of the second main body.

[0046] In some embodiments, the first main body and the first connecting member enclose a ring structure, and the second main body and the second connecting member also enclose a ring structure. During the assembly process, after installing the first shackle 210 on the cross beam 100, by passing the first end 2011 or the second end 2012 of the second main body through the ring structure formed by the first main body and the first connecting member, and then passing the second connecting member sequentially through the first end 2011 of the second main body and the through hole 21 of the piece to be lifted 20 and connecting it to the second end 2012 of the second main body, in this way, the connection between the piece to be lifted 20 and the lifting assembly 10 is completed.

[0047] In a possible design, as Figure 5 shown, the cross beam 100 is provided with a lifting lug 111, and the lifting lug 111 is located in the middle area of the cross beam 100 in its own length direction. The lifting lug 111 is specifically a structure for connecting with a lifting device. Specifically, the lifting lug 111 protrudes from one side surface of the cross beam 100, and the lifting lug 111 is provided with a second connecting hole 1111 for connecting the lifting device. According to the above embodiments, by arranging the lifting lug 111 in the middle area of the cross beam 100 in its own length direction, it is beneficial to maintain the balance of the lifting assembly 10, so as to improve the stability of the lifting assembly 10 during the process of lifting the piece to be lifted 20.

[0048] In a possible design, as Figure 6 shown, a plurality of lifting lugs 111 are arranged at intervals on the cross beam 100, and the lifting assembly 10 further includes a plurality of intermediate members, and the plurality of intermediate members are arranged in one-to-one correspondence with the plurality of lifting lugs 111. One end of each intermediate member is hinged to the corresponding lifting lug 111, and the other end is used for connecting with a lifting device. With such an arrangement, any two intermediate members and the cross beam 100 can enclose a triangular structure, so that the stability of the cross beam 100 during the process of the lifting device lifting the cross beam 100 can be improved.

[0049] Alternatively, the intermediate component can be a rigid component or a flexible component. For example, the intermediate component is a flexible component, such as a chain or rope. Due to the high flexibility of the flexible component, it can deform according to the actual stress on the beam 100, thereby facilitating a more uniform stress distribution on the beam 100. Furthermore, the use of a rigid component can reduce the sway of the beam 100, thereby maintaining the stability of the suspended component 20.

[0050] In some optional embodiments, the crossbeam 100 may be a T-beam or an I-beam. Figure 7 As shown, the crossbeam 100 is a T-beam, and the crossbeam 100 includes a first plate 110 and a second plate 120. The width direction of the first plate 110 and the width direction of the second plate 120 are arranged at an angle. The first plate 110 has a connection area on the first side surface in the thickness direction. The connection area is located in the middle of the first side surface in the width direction of the first plate 110, and the second plate 120 is installed in the connection area. In this embodiment, the lifting lug 111 is installed on the side of the first plate 110 facing away from the second plate 120. Optionally, the first plate 110 and the second plate 120 can be connected to form an integral structure by welding or integral molding. For example, the first plate 110 and the second plate 120 can be connected to form an integral structure by integral casting.

[0051] In one possible design, Figure 7 As shown, the crossbeam 100 further includes a plurality of reinforcements 130, which are located on opposite sides of the second plate 120 in the thickness direction thereof. The reinforcements 130 located on the same side are spaced apart, and each reinforcement 130 is connected to the first plate 110 and the second plate 120. The reinforcements 130 improve the stability of the connection between the first plate 110 and the second plate 120, thereby increasing the structural strength of the entire crossbeam 100.

[0052] In one possible design, at least one reinforcement portion 130 is provided between any two adjacent first connection holes 121 on any side surface of the second plate body 120. It is worth noting that in the embodiment of the present application, the width direction of the first plate body 110 can be a horizontal direction, and the width direction of the second plate body 120 can be a vertical direction. In this embodiment, the first connection hole 121 can be provided within the height range of the reinforcement portion 130 in the second plate body 120, that is, in the second plate body 120, the height range of the area where the first connection hole 121 is located is within the height range of the area where the reinforcement portion 130 is located. In this way, it is beneficial to reduce the size of the second plate body 120 in the vertical direction, thereby reducing the space occupied by the hoisting assembly 10 in the height direction, so as to facilitate use in venues with a lower height limit.

[0053] Optionally, the reinforcing portion 130 may be a plate-like structure, a columnar structure, or other irregular-shaped structures. In a possible design, the reinforcing portion 130 is a right-angled triangular plate-like structure. One of the right-angled sides of the reinforcing portion 130 is connected to the first plate body 110, and the other right-angled side is connected to the second plate body 120. The reinforcing portion 130 in the form of a triangular plate-like structure has stronger supporting ability, which is beneficial to further improving the structural strength of the cross beam 100 and enhancing the reliability of the hoisting assembly 10.

The hoisting device is connected to the cross beam 100 in the hoisting assembly 10. Optionally, the hoisting device may be a crane, a lift, a traveling crane, etc., and is not limited uniquely here.

[0056] Compared with the related art, the hoisting system provided by the embodiment of the present application directly connects through the first shackle 210 and the second shackle 220 in the hoisting assembly 10, and connects with the piece to be hoisted 20 through the second shackle 220 to hoist only the piece to be hoisted 20. In this way, not only can the total height of the hoisting assembly 10 be effectively reduced, but also the swaying amplitude of the piece to be hoisted 20 during the moving process can be effectively reduced, which is beneficial to improving the safety performance and enhancing the hoisting accuracy.
