Description

Technical Field

[0001] This application relates to the field of lifting equipment technology, for example to a hook for a lifting frame and a lifting frame. Background Technology

[0002] Currently, among existing hoisting equipment, four-point hoisting structures offer high safety. However, because the dimensions of the hoisting legs are fixed and it involves four-corner hoisting, it occupies a significant amount of space. Furthermore, during the hoisting process, all four hooks must be in position before lifting can begin, requiring manual intervention to ensure the hoisting frame is properly attached to / detached from the object being hoisted; otherwise, it is difficult to meet the lifting conditions. Therefore, it is essential to ensure that the hoisting environment is permissible for personnel to enter.

[0003] In the process of implementing the embodiments of this disclosure, it was found that at least the following problems exist in the related technology: the existing four-legged hoisting frame hoisting structure requires the hoisting environment to be able to accommodate / allow operators to enter. Summary of the Invention

[0004] To provide a basic understanding of some aspects of the disclosed embodiments, a brief summary is given below. This summary is not intended as a general commentary, nor is it intended to identify key / important components or describe the scope of protection of these embodiments, but rather as a prelude to the detailed description that follows.

[0005] This disclosure provides a hook and a lifting frame for a lifting frame, to solve the problem that the lifting environment of existing four-legged lifting frames needs to be able to accommodate / allow operators to enter.

[0006] In some embodiments, the hook for the lifting frame includes: a hook body, which is flat; and an anti-detachment portion extending along the flat surface at one end thereof.

[0007] In some embodiments, the hoisting frame includes: a hoisting frame including a transverse hoisting beam and a longitudinal hoisting beam, with transverse hoisting beams respectively provided at both ends of the longitudinal hoisting beam; hoisting legs provided at the corners of the hoisting frame, and having one or more hook mounting positions thereon; and the aforementioned hooks provided at the hook mounting positions.

[0008] The lifting hook and lifting frame provided in this disclosure can achieve the following technical effects:

[0009] The lifting hook of the lifting frame in this embodiment is flat. When lifting a workpiece, the flat surface of the hook is parallel to the lifting direction, making it easier for the hook to enter the lifting hole of the workpiece. It can easily engage / disengage from the lifting hole without manual intervention, eliminating the need for operator space in the lifting environment and facilitating lifting operations. Furthermore, it is suitable for lifting environments where operator access is not permitted (or unsuitable).

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in the present disclosure can be combined with each other.

[0032] Combination Figures 1 to 7 As shown, this embodiment of the present disclosure provides a hook 40 for a lifting frame, including a hook body that is flat; and an anti-detachment portion 43 extending along the flat surface at one end therefrom.

[0033] The hook of this embodiment is used in a lifting frame and is flat in shape. When lifting a workpiece, the flat surface of the hook 40 is parallel to the lifting direction, making it easier for the hook to enter the lifting hole of the workpiece. It can be easily engaged / disengaged from the lifting hole on the workpiece without manual intervention, eliminating the need for operator space in the lifting environment and facilitating lifting operations. For example, it is suitable for crane lifting operations. Furthermore, it is suitable for lifting environments where personnel are not permitted (or are not suitable) to enter. For example, industrial environments with radiation or corrosive atmospheres, specifically hot chambers, chemical plants, and other industrial environments.

[0034] In some embodiments, such as Figure 5 and Figure 6 As shown, the hook body includes a connecting part 41, a holding part 42, and an anti-detachment part 43. The connecting part 41 is used to be mounted on the lifting frame; for example, the connecting part 41 is located in the hook mounting position 22 of the lifting leg 20 of the lifting frame. One end of the holding part 42 is connected to the connecting part 41, and the other end is connected to the anti-detachment part 43, that is, the two ends of the holding part 42 are respectively provided with the connecting part 41 and the anti-detachment part 43. On the flat surface of the hook body, the anti-detachment part 43 protrudes from the holding part 42.

[0035] Optionally, the connecting part 41, the hanging part 42, and the anti-detachment part 43 are arranged coaxially. That is, they are symmetrical along the longitudinal direction of the hook body, which facilitates installation.

[0036] Optionally, a limiting step 44 is formed between the connecting part 41 and the hanging part 42. When the hook 40 is inserted into the hook mounting position 22 of the lifting leg 20, the limiting step 44 abuts against the wall surface of the lifting leg 20, thus playing a limiting role.

[0037] Optionally, such as Figure 5 As shown, the end face of the anti-detachment part 43 is arc-shaped, which facilitates its entry into the lifting hole of the lifted part.

[0038] Optionally, the connecting part 41, the hanging part 42, and the anti-slip part 43 are all cuboid, and the size of the connecting part 41 is smaller than the size of the hanging part 42, and the size of the hanging part 42 is smaller than the size of the anti-slip part 43.

[0039] Optionally, one pair of opposite sides of the hook 40 is flat and parallel, while the other pair of opposite sides is stepped. That is, the hook 40 is flat and arrow-shaped.

[0040] Optionally, the structure of the connecting part 41 of the hook 40 is not limited, and can be determined according to the connection method between the hook 40 and the lifting leg 20 of the lifting frame. For example, the connecting part 41 is inserted into the hook mounting position 22 of the lifting leg 20 of the lifting frame, or the hook 40 is fixedly connected to the hook mounting position 22 of the lifting leg 20 through the connecting part 41, such as by welding.

[0041] Of course, the structure of the hook 40 in this embodiment is not limited to the aforementioned structure; other flat structures that can be attached to the lifting point of the lifted part are also acceptable.

[0042] Combination Figures 1 to 7 As shown, this embodiment of the present disclosure provides a lifting frame, including a lifting frame 10, lifting legs 20, and the aforementioned hooks 40; the lifting frame 10 includes transverse lifting beams 11 and longitudinal lifting beams 12, with transverse lifting beams 11 respectively provided at both ends of the longitudinal lifting beams 12; the lifting legs 20 are located at the corners of the lifting frame 10, and one or more hook mounting positions 22 are provided thereon. The hooks 40 are provided on the hook mounting positions 22.

[0043] The lifting frame provided in this embodiment employs the aforementioned flat hook, which allows the flat surface of the hook 40 to be parallel to the lifting direction when lifting the workpiece. This makes it easier for the hook to enter the lifting hole of the workpiece, allowing for smooth engagement / disengagement without manual intervention. This eliminates the need for pre-reserved operating space for personnel, facilitating lifting operations. For example, it is suitable for crane lifting operations. Therefore, it is suitable for environments with limited space, where operator intervention is inconvenient or difficult.

[0044] In this embodiment, a holding portion 42 is formed between the anti-detachment portion 43 of the hook 40 and the wall surface of the lifting leg 20 to ensure that the hook 40 is held in place by the lifting hole of the lifted part.

[0045] Optionally, the lifting frame provided in this disclosure can be used in lifting environments where personnel are not allowed (or are not suitable) to enter. For example, it can be used in industrial environments with radiation or corrosive atmospheres, such as hot chambers, chemical plants, and other industrial environments.

[0046] Optionally, the lifting frame provided in this embodiment is suitable for lifting environments where space is limited and operators cannot easily access. For example, in working environments used for routine lifting operations, especially in working environments where space is narrow and it is inconvenient for operators to enter the site for operation and intervention.

[0047] Optionally, the hooks 40 are arranged on the hook mounting positions 22 of the lifting legs 20 with all facing the same side. Moving the lifting frame in one direction allows all the hooks 40 on the multiple lifting legs 20 to enter / exit the lifting holes of the lifted part, completing the engagement / disengagement with the lifting holes on the lifted part, which facilitates the lifting operation of the lifting frame.

[0048] The structure of the lifting frame 10 in this embodiment is not limited and can be determined according to the structural shape of the lifted component (e.g., equipment or parts). Currently, the lifting points (e.g., lifting lugs) on most equipment and parts are arranged in a square pattern for ease of operation. Therefore, in some embodiments, the lifting frame 10 is square in shape, that is, the lines connecting the four corners of the lifting frame 10 form a square. The lifting space formed by the lifting legs 20 is also square, which facilitates the lifting of lifted components with a square arrangement of lifting points. However, it is not limited to this; other lifted components with fewer than four lifting points arranged in a non-square pattern can also be lifted. The only difference is that the lifting frame may not be able to maintain a horizontal position during lifting, but this does not affect the lifting effect. Of course, the number of lifting points is not limited to four; it can be more than four, depending on actual needs. Currently, the lifting points (e.g., lifting lugs) on equipment and parts in hot chamber environments are mostly arranged in a square pattern, which is suitable for environments such as hot chambers where it is inconvenient for operators to intervene.

[0049] In some embodiments, combined with Figure 4 and Figure 7 As shown, the lifting leg 20 is provided with one or more hook mounting positions 22. These are used for lifting the object being lifted, such as equipment or components.

[0050] Optionally, as shown in Figure 7, when there are multiple hook mounting positions 22, the multiple hook mounting positions 22 are arranged along the length direction of the lifting leg 20. This enables the lifting point to move in a direction perpendicular to the plane of the lifting frame 10 (defined as the Z direction). The installation position of the hook 40 on the lifting leg 20 can be determined according to the position and height of the lifted part, etc., making lifting flexible and operation convenient.

[0051] In this embodiment, one end of the lifting leg 20 is a connecting end 201, which is disposed on the lifting frame 10 and is used to connect with the transverse lifting beam 11 of the lifting frame 10; the other end is a lifting end 202, on which a hook mounting position 22 is provided for connecting and mounting a hook 40; and a hanging part 42 is formed between the anti-detachment part 43 of the hook 40 and the side wall surface of the lifting end 202.

[0052] In some embodiments, such as Figure 8 As shown, the cross-sectional dimension of the connecting end 201 of the lifting leg 20 is larger than that of the lifting end 202, so that during the lifting operation, the vertical line m of the connection point of the connecting end 201 passes through the hanging part 42 of the hook 40. Therefore, during the lifting operation, the support force line l of the hook 40's hanging part 42 on the lifted part can be close to or coincide with the connection point of the connecting end of the lifting leg 20 (generally the center of the end face of the connecting end, such as the connecting structure 21), making the entire lifting frame structure stable under force and preventing additional bending moments.

[0053] Optionally, the lifting leg 20 has a trapezoidal cross-section along its length. In this embodiment, the larger end serves as the connecting end 201, and the smaller end serves as the lifting end 202. The lifting leg has at least two cross-sections along its length, defined as a first cross-section and a second cross-section, respectively, and the first and / or second cross-sections are trapezoidal.

[0054] Optionally, both the first and second cross-sections of the lifting leg 20 are trapezoidal. In this case, the lifting leg 20 as a whole is frustum-shaped.

[0055] Optionally, the first or second cross-section of the lifting leg 20 is trapezoidal.

[0056] Optionally, the first or second cross-section of the lifting leg 20 is a right trapezoid.

[0057] Optionally, the connecting end 201 of the lifting leg 20 has a trapezoidal cross-section, and the lifting end 202 has a square cross-section. This facilitates the installation of the hook 40.

[0058] Specifically, in combination Figure 7 and Figure 8 As shown, the lifting leg 20 includes a connecting section 24 and a lifting section 25. The lifting section 25 has a square cross-section and a hook 40 is provided on its side wall. The connecting section 24 has a trapezoidal cross-section, with its smaller end connected to the lifting section 25 and its larger end located on the lifting frame 10. A holding part 42 is formed between the anti-detachment part 43 of the hook 40 and the wall surface of the lifting leg 20 to hold the lifting hole 61 of the lifted component 60.

[0059] Optionally, the first and second cross sections of the connecting segment 24 are trapezoidal.

[0060] Optionally, the first or second cross-section of the connecting segment 24 is trapezoidal.

[0061] Optionally, such as Figure 7 As shown, the first or second cross-section of the connecting segment 24 is a right trapezoid.

[0062] In some embodiments, combined with Figure 1 As shown, in the hoisting frame 10, the transverse lifting beam 11 includes a first transverse lifting beam 111 and a second transverse lifting beam 112; the first transverse lifting beam 111 is disposed at one end of the longitudinal lifting beam 12, and the second transverse lifting beam 112 is disposed at the other end of the longitudinal lifting beam 12; and the first transverse lifting beam 111 and the second transverse lifting beam 112 are arranged in parallel. In this embodiment, the hoisting frame 10 is I-shaped, and the two ends of the first transverse lifting beam 111 and the two ends of the second transverse lifting beam 112 constitute the four corners of the hoisting frame 10.

[0063] Optionally, such as Figure 1 As shown, the first transverse lifting beam 111 and the second transverse lifting beam 112 have the same structure, both being strip-shaped and narrowing at both ends to facilitate connection with the lifting leg 20.

[0064] In this embodiment, for equipment or parts with different lifting point dimensions, specialized lifting racks are required. This necessitates storing lifting racks of various sizes, resulting in wasted space, especially in space-constrained work environments. Furthermore, the variety of lifting rack sizes increases the workload for maintenance personnel in replacement and relocation operations. Therefore, in some embodiments, the length of the longitudinal lifting beam 12 is adjustable; and / or, the position of the lifting legs 20 is adjustable in the direction of the transverse lifting beam 11.

[0065] In this embodiment, the length of the longitudinal lifting beam 12 of the lifting frame 10 is adjustable, allowing the longitudinal (defined as X-direction) spacing between the four lifting legs 20 installed at the four corners of the lifting frame 10 to be adjusted. Furthermore, by adjusting the position of the lifting legs 20 in the direction of the transverse lifting beam, the transverse (defined as Y-direction) spacing between the four lifting legs 20 is also adjustable. Therefore, the lifting space formed by the lifting legs 20 has an adjustable length in both the longitudinal and / or transverse directions, making it suitable for lifting components of different sizes. This allows for the lifting of various equipment or components of different sizes. When applied in environments with limited space, this single lifting frame can lift various equipment or components of different sizes within a heated room, eliminating the need for multiple lifting frames of different specifications, effectively saving space, and reducing the workload of maintenance personnel in replacement and relocation operations.

[0066] Optionally, the length of the longitudinal lifting beam 12 is adjustable; and the position of the lifting legs 20 can be adjusted in the direction of the transverse lifting beam 11. This allows for movement of the lifting point in a direction perpendicular to the plane of the lifting frame 10 (defined as the Z-direction), while also enabling adjustment of the lifting point in three dimensions: transverse (Y-direction), longitudinal (X-direction), and Z-direction. This makes lifting more flexible and operation more convenient.

[0067] In this embodiment, the method of adjusting the length of the longitudinal lifting beam 12 is not limited. Optionally, in combination with Figure 2 As shown, the longitudinal lifting beam 12 includes a first adjusting part and a second adjusting part, which are symmetrically arranged, allowing the length of the longitudinal lifting beam 12 to be adjusted to both sides. Therefore, when adjusting the length of the longitudinal lifting beam 12, it can be adjusted symmetrically, maintaining the relative position of the lifting points when the lifting point positions are fixed. For example, the lifting points are always located at the center of the lifting frame 10, ensuring the lifting frame remains horizontal during the lifting process.

[0068] Optionally, the first and second adjusting parts are adjusted synchronously. This allows the length of the longitudinal lifting beam 12 to be adjusted synchronously to both sides.

[0069] In this embodiment, the structure of the first adjustment part and the second adjustment part is not limited, as long as the length of the longitudinal lifting beam 12 can be adjusted.

[0070] In some embodiments, the first adjusting part and the second adjusting part have the same structure, both including a sleeve structure or a telescopic structure.

[0071] In some embodiments, such as Figure 2As shown, the longitudinal suspension beam 12 includes a main body 121, a first end 122, and a second end 123. The main body 121 is a hollow cylinder. The first end 122 is sleeved with the first end of the main body 121, and the sleeved position is adjustable. The second end 123 is sleeved with the second end of the main body 121, and the sleeved position is adjustable. In this embodiment, the longitudinal suspension beam 12 is a box girder structure, and its length is adjustable by adjusting the sleeved position of the first end 122 and the second end 123 with the main body 121.

[0072] Optionally, one or more first pin holes 124 are provided on the first end and the second end of the main body 121, and multiple second pin holes 125 are provided on the first end 122 and the second end 123, respectively. When the first pin hole 124 on the first end of the main body 121 is aligned with the second pin hole 125 on the first end 122, and the first pin hole 124 on the second end of the main body 121 is aligned with the second pin hole 125 on the second end 123, the two ends of the main body 121 are fixed relative to the first end 122 and the second end 123 respectively by means of a pin 126 and a nut 127.

[0073] Optionally, there is one first pin hole 124 and multiple second pin holes 125. By aligning and fixing one first pin hole 124 with different second pin holes 125, the length of the longitudinal lifting beam 12 can be adjusted.

[0074] Optionally, there may be multiple first pin holes 124 and multiple second pin holes 125; and the number of second pin holes 125 may be greater than or equal to the number of first pin holes 124. By adjusting the alignment of the first pin holes 124 and the second pin holes 125, the length of the longitudinal lifting beam 12 can be adjusted. Moreover, the more first pin holes 124 used for alignment, the more stable the connection. Compared to having only one first pin hole 124 for alignment, when there are multiple first pin holes 124 for alignment and fixing, the weight borne by the main body 121 is transmitted by the pins 126 inside the pin holes, avoiding contact transmission between the main body 121 and the first end 122 and the second end 123, reducing friction between them, and improving service life. When there is only one first pin hole 124 for alignment and fixing, the main body 121 and the first end 122 or the second end 123 form a hinge point at the pin hole. Under force, the main body 121 and the first end 122 or the second end 123 rotate relative to each other, and the main body 121 contacts the first end 122 and the second end 123 and transmits the force through the contact point.

[0075] Optionally, the number of first pin holes 124 is two; the number of second pin holes 125 is more than two. Optionally, the number of second pin holes 125 is three, four, or more. This can be determined based on the range of length adjustment to be achieved in the longitudinal direction.

[0076] Optionally, there may be multiple first pin holes 124, which are equidistant from each other. Correspondingly, there may be multiple second pin holes 125, which are equidistant from each other, and the equidistant distance is equal to the equidistant distance between the first pin holes 124.

[0077] Optionally, one end of the pin 126 is provided with an annular operating part 1261, which facilitates the picking and connecting operations of the robot arm.

[0078] Optionally, the first pin hole 124 and the second pin hole 125 are arranged in a horizontal direction to provide better locking and fastening.

[0079] In some embodiments, such as Figure 3 As shown, the longitudinal suspension beam 12 includes a main body 121, a first telescopic part 128, and a second telescopic part 129. The first telescopic part 128 is connected to a first end of the main body 121; the second telescopic part 129 is connected to a second end of the main body 121. In this embodiment, both ends of the longitudinal suspension beam 12 are telescopic parts. By adjusting the lengths of the first telescopic part 128 and the second telescopic part 129, the length of the longitudinal suspension beam 12 can be adjusted.

[0080] Optionally, both the first telescopic section 128 and the second telescopic section 129 are telescopic rods. The longitudinal length is adjustable by controlling the relative proximity or distance of the transverse lifting beam 11.

[0081] In some embodiments, combined with Figure 1 and Figure 4 As shown, the hoisting frame also includes a first connecting member 30. The first connecting member 30 is disposed at the end of the transverse lifting beam 11, and the position of the first connecting member 30 is adjustable; the connecting end of the hoisting leg 20 is provided with a connecting structure 21 that cooperates with the first connecting member 30.

[0082] In this embodiment, the method by which the lifting leg 20 can be adjusted in the direction of the transverse lifting beam 11 is not limited. In some embodiments, such as Figure 4 As shown, the end of the transverse lifting beam 11 is provided with a through hole 113, and the first connecting member 30 passes through the through hole 113. The end of the connecting member 30 is connected to the connecting structure 21 on the connecting end of the lifting leg 20. There are multiple through holes 113; or, the through hole 113 includes a strip-shaped through hole, and the length direction of the strip-shaped through hole is consistent with the length direction of the transverse lifting beam 11.

[0083] Optionally, there may be multiple through holes 113. That is, multiple through holes 113 are provided at the ends of the transverse lifting beam 11; by inserting the first connecting member 30 into the through holes 113 at different positions, the lifting leg 20 can be adjusted in the transverse direction.

[0084] Optionally, such as Figure 4As shown, the through hole 113 includes a strip-shaped through hole, and the length direction of the strip-shaped through hole is consistent with the length direction of the transverse lifting beam 11. By using the strip-shaped through hole 113, when adjusting the connection position of the lifting leg 20, it is not necessary to remove the first connecting member 30 from the through hole 113, or even to disconnect the first connecting member 30 from the connection mechanism on the lifting leg 20, to adjust the connection position. This makes operation convenient.

[0085] Optionally, the inner wall of the slotted through-hole is serrated. This increases the friction between the inner wall of the slotted through-hole and the outer wall of the first connector 30 (screw), improving the effective connection between the first connector 30 and the lifting leg 20. It also provides multiple locking positions for the first connector 30, allowing it to be held in place when its connection position within the slotted through-hole is changed. Furthermore, it ensures that the positions of the lifting legs 20 at the four corners of the lifting frame 10 remain consistent.

[0086] Optionally, the first connector 30 includes a screw, and the connecting structure 21 on the connecting end of the lifting leg 20 includes a screw hole. After the screw passes through the through hole 113, it is screwed into the screw hole on the connecting end of the lifting leg 20 on the other end face.

[0087] Alternatively, the screw may be an internal hexagon head screw.

[0088] In some embodiments, such as Figure 3 and Figure 4 As shown, the lifting frame also includes an anti-rotation structure 114; the anti-rotation structure 114 is disposed on the connecting surface at the end of the transverse lifting beam 11; after the lifting leg 20 is fixedly connected, the connecting end of the lifting leg 20 is located within the anti-rotation structure 114. This structure serves a positioning function during connection, facilitating finding the correct connection position, and also prevents the lifting leg 20 from rotating after fixed connection. In this embodiment, the connecting surface is the wall surface where the end of the transverse lifting beam 11 connects to the connecting end of the lifting leg 20.

[0089] Optionally, the anti-rotation structure 114 includes a stop. A notch is provided on the connecting surface at the end of the transverse lifting beam 11 so that the connecting end of the lifting leg 20 is located within the stop, which serves to connect and position the lifting leg 20 while also preventing it from rotating.

[0090] Optionally, both ends of the first transverse lifting beam 111 and both ends of the second transverse lifting beam 112 are provided with stop surfaces.

[0091] Combination Figure 9 and Figure 10As shown, when using the lifting frame of this embodiment, the longitudinal (X-direction) and transverse (Y-direction) lifting point positions of the lifted component 60 are first determined. Based on these lifting point positions, the length of the longitudinal lifting beam 12 on the lifting frame and / or the connection position of the lifting legs 20 on the transverse lifting beam 11 are adjusted so that the lifting space formed by the four lifting legs 20 matches the lifting point of the lifted component 60. After lifting the lifting frame using the crane hook (or the gripping end of a robotic arm), the lifting frame is moved to the vicinity of the lifting point and then translated so that the lifting hook 40 of the lifting frame enters the lifting hole 61 of the lifting point of the lifted component 60. Then, the lifting frame is raised, and the lifting hook 40 of the lifting frame engages with the lifting hole 61 of the lifting point on the lifted component 60, thus achieving the lifting of the lifted component 60. Furthermore, the lifted component 60 can be moved by the movement of the crane. Once the lifting is in place, lower the lifting frame until the lifted part 60 lands on the ground. Then, continue to lower the lifting frame a certain distance until the lifting hook 40 of the lifting frame disengages from the lifting hole 61 of the lifting point of the lifted part 60. Finally, move the lifting frame horizontally to separate the lifting frame from the lifted part 60.

[0092] In some cases, the distance from the lifting point of the hoisted part 60 to the upper surface of the lifting point is different. In this case, the installation position of the hook 40 can be adjusted, and the height of the lifting leg 20 can be adjusted in the Z direction to ensure that the hook 40 can reach the position of the lifting point (lifting hole 61) of the hoisted part 60, while further improving stability.

[0093] In the lifting frame of this disclosure, it is operated by a crane or a robot. Therefore, the lifting frame must have lifting points to ensure that the crane or robot can operate the lifting frame. In some embodiments, the lifting frame further includes lifting point structures 50, which are disposed on the lifting frame 10. They are used to cooperate with the hook of the crane or the gripping end of the robot.

[0094] Optionally, the lifting point structure 50 is positioned at the center of the lifting frame 10. This ensures the balance of the lifting frame during the lifting process.

[0095] Optionally, the lifting point structure 50 includes a fixing plate 51 and a lifting ring 52. The fixing plate 51 is disposed on the longitudinal lifting beam 12, and the lifting ring 52 is disposed on the fixing plate 51.

[0096] In some embodiments, the number of longitudinal suspension beams 12 is two or more; two or more longitudinal suspension beams 12 are arranged in parallel to form a longitudinal suspension beam group; the transverse suspension beam 11 includes a first transverse suspension beam 111 and a second transverse suspension beam 112; the first transverse suspension beam 111 is disposed at one end of the longitudinal suspension beam group, and the second transverse suspension beam 112 is disposed at the other end of the longitudinal suspension beam group. This enhances stability and balance.

[0097] Optionally, the lifting point structure 50 is located at the midpoint of the longitudinal direction of the longitudinal lifting beam assembly.

[0098] Optionally, there are two longitudinal lifting beams 12, which are arranged in parallel to form a longitudinal lifting beam group. The fixing plate 51 of the lifting point structure 50 is located at the middle of the longitudinal direction of the longitudinal lifting beam group, and the lifting ring 52 is located at the middle of the fixing plate 51 between the two longitudinal lifting beams 12.

[0099] Optionally, the longitudinal lifting beam 12 adopts the following... Figure 2 In the box girder structure shown, the annular operating part 1261 of the pin 126 is located inside the longitudinal lifting beam assembly, and the nut 127 is located outside the longitudinal lifting beam assembly. The outer location of the nut 127 facilitates the operation of the robot arm to fit the nut 127 onto the pin 126.

[0100] In some embodiments, the lifting frame further includes rollers 23 disposed at the bottom of the lifting legs 20, facilitating the movement of the lifting frame.
