Description

Technical Field

[0001] The present application relates to the technical field of hoisting equipment, and in particular to a hoisting equipment. Background Art

[0002] Flanges are parts that connect shafts to each other and are also a large number of parts in pressure vessels. Flanges in large mechanical devices and large pressure vessels are heavy, and it is difficult to carry them manually during flange processing, transportation, and assembly. Therefore, lifting equipment is needed to transport flanges to various processing stations.

[0003] The lifting equipment can lift the flange through lifting tools such as hooks, lifting straps, lifting rings, etc. In the related art, one of the common methods for connecting the lifting tool and the flange is: drilling a mounting hole on the flange, and then locking the mounting hole with the bolts on the lifting tool to fasten the lifting tool and the flange, and then transporting the flange.

[0004] However, there is no suitable lifting tool for lifting before drilling the flange. Even after drilling, when the flange diameter is large and the bolt hole is small, the lifting bolts used are small, and there are safety hazards when lifting with bolts. In addition, for flanges with larger mass, the welding requirements between the bolts and the lifting tools are higher. Flanges of different specifications have different bolt specifications. Therefore, the versatility is poor and the processing cost is high. On the other hand, manual operation is required during the locking process of the bolts and the mounting holes, and the installation process is time-consuming and labor-intensive.

[0005] The second commonly used method between the hook and the flange is to use three steel plate hooks to support the lifting, but this method is usually only suitable for flanges with a thickness of less than 80 mm. Thicker flange steel plate hooks need to be specially made and due to structural reasons, they are easy to fall off after being lifted, posing a safety hazard. Utility Model Content

[0006] The present application provides a lifting device which can solve the problem that the lifting process is complicated, time-consuming, labor-intensive and has potential safety hazards.

[0007] The present application provides a lifting device, which includes:

[0008] Horizontal support;

[0009] A plurality of clamping parts, wherein the clamping parts are slidably connected to the horizontal bracket along a horizontal direction;

[0010] A first vertical bracket, one end of which is connected to the horizontal bracket;

[0011] A second vertical bracket, the second vertical bracket can be raised and lowered in a vertical direction, one end of the second vertical bracket is movably connected to the first vertical bracket, and the other end of the second vertical bracket is used to be connected to a lifting device;

[0012] A connecting rod assembly, one end of which is rotatably connected to the second vertical bracket, and the other end of which is rotatably connected to the clamping portion;

[0013] Wherein, the descent of the second vertical bracket can drive the plurality of clamping parts to move away from each other, and the ascent of the second vertical bracket can drive the plurality of clamping parts to move toward each other.

[0014] The hoisting equipment provided by the present application can be used to clamp the flange through multiple clamping parts. The adjusting hook slides on the first vertical bracket, and the clamping parts can be driven to move closer to or farther from each other through the connecting rod assembly. Specifically, the adjusting hook rises in the vertical direction and can drive the clamping parts to move closer to each other through the connecting rod assembly, so that the flange can be clamped between the clamping parts, thereby achieving the connection reliability between the clamping parts and the flange, and reducing the possibility of the flange falling off the clamping parts during the transportation of the flange, causing safety hazards. When the flange moves to the target station, the adjusting hook can descend in the vertical direction, and drive the two clamping parts away from each other through the connecting rod assembly, so that the clamping part releases the flange.

Sliding in the horizontal direction includes moving in the direction close to the flange in the horizontal direction, and also includes moving in the direction away from the flange in the horizontal direction, so that the clamping parts can be driven to approach each other to clamp the flange through the connecting rod assembly, and can also be driven to move away from each other to release the flange.

[0018] Furthermore, due to the force transmission coordination between the components of the connecting rod assembly, it is beneficial to ensure that the clamping part moves smoothly in the horizontal direction under the action of the connecting rod assembly, thereby preventing the clamping part from getting stuck.

[0025] According to an embodiment of the present application, the dehooking portion is slidably connected to the first vertical bracket along the vertical direction, so that the dehooking portion has a first position and a second position;

[0026] When the adjusting hook is located at the engaging portion, the unhooking portion is located at the first position, and a vertical gap exists between the unhooking portion and the engaging portion;

[0027] The adjusting hook can drive the unhooking portion to slide, so that when the unhooking portion is located at the second position, the unhooking portion is connected to the engaging portion.

[0028] According to an embodiment of the present application, the engaging portion is provided with an engaging surface facing the horizontal bracket, and the adjusting hook is hooked with the engaging surface to fix the clamping portion;

[0029] When the unhooking portion is located at the second position, the unhooking portion is in contact with the engaging surface.

These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0063] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0064] The present application provides a hoisting device that can be used to clamp a part to be hoisted and move the part to be hoisted to a corresponding processing station. The part to be hoisted can be a flange, a cylinder, a steel coil, or a thick blind plate. The present application takes the flange part (flange for short) as an example for description.

[0065] Flange, also known as flange flange or flange, is a part that connects shafts to each other and is also a large number of pipe parts in pressure vessels. In large-scale mechanical devices and large-scale pressure vessels, the flange mass is relatively large. During the flange processing, transportation, and assembly process, it is difficult to carry it manually. Therefore, it is necessary to use lifting equipment to transport the flange to each processing station.

[0066] The lifting equipment can lift the flange through a lifting device such as a hook, a lifting strap, or a lifting ring. After the lifting device is fixedly connected to the flange, the flange can be transported through the lifting device. In the related art, the connection method between the lifting device and the flange is usually to drill a mounting hole on the flange, and then tighten the mounting hole with the bolts on the lifting device to connect the lifting device to the flange, and then transport the flange.

[0067] However, when the flange is locked with bolts and mounting holes, on the one hand, there is no suitable lifting tool before drilling the flange. Even after drilling, when the flange diameter is large and the bolt hole is small, the lifting bolts used are small, and there are safety hazards when lifting with bolts. In addition, for flanges with larger mass, the welding requirements between the bolts and the lifting tools are higher, and the specifications of the bolts for flanges of different specifications are also different. Therefore, the versatility is poor and the processing cost is high. On the other hand, manual operation is required during the locking process of the bolts and mounting holes, and the installation process is time-consuming and labor-intensive.

[0068] The second commonly used method between the hook and the flange is to use three steel plate hooks to support the lifting, but this method is usually only suitable for flanges with a thickness of less than 80 mm. Thicker flange steel plate hooks need to be specially made and due to structural reasons, they are easy to fall off after being lifted, posing a safety hazard.

[0069] Based on the above technical problems, the applicant has improved the structure of the lifting equipment. In the embodiment of the present application, the lifting equipment 100 can slide in the horizontal direction X through multiple clamping parts 120 to clamp the flange 200. Specifically, since the second vertical bracket 133 can be raised and lowered in the vertical direction, and one end of the connecting rod assembly is rotatably connected to the second vertical bracket 133, and the other end is rotatably connected to the clamping part 120, the multiple clamping parts 120 can be driven away from each other by the second vertical bracket 133 descending to release the flange 200. The multiple clamping parts 120 can be driven close to each other by the second vertical bracket 133 rising, so that the flange 200 can be clamped between the clamping parts 120, thereby achieving the connection reliability between the clamping part 120 and the flange 200, and reducing the possibility of the flange 200 falling off during transportation, resulting in safety hazards.

[0070] The hoisting device 100 provided in the present application is described below with reference to the accompanying drawings and in combination with specific embodiments.

[0071] See also Figures 1 to 6 As shown, the hoisting device 100 of the embodiment of the present application may include a horizontal bracket 110 , a clamping portion 120 , a first vertical bracket 131 , a second vertical bracket 133 and a connecting rod assembly 140 .

[0072] The number of the clamping parts 120 is multiple. It should be noted that in the present application, multiple can refer to more than two. The multiple clamping parts 120 are slidably connected to the horizontal bracket 110 along the horizontal direction (for example, the X direction). Therefore, the multiple clamping parts 120 approaching each other along the horizontal direction X can be used to clamp the flange 200. The multiple clamping parts 120 moving away from each other along the horizontal direction X can be used to release the flange 200.

[0073] The first end of the first vertical bracket 131 can be connected to the horizontal bracket 110. The second vertical bracket 133 can be raised and lowered along the vertical direction (e.g., Y direction). One end of the second vertical bracket 133 is movably connected to the first vertical bracket 131. The other end of the second vertical bracket 133 can be used to be connected to a lifting device.

[0074] The connecting rod assembly 140 can be used to connect the second vertical bracket 133 and the clamping portion 120. One end of the connecting rod assembly 140 is rotatably connected to the second vertical bracket 133, and the other end of the connecting rod assembly 140 is rotatably connected to the clamping portion 120.

[0075] The second vertical bracket 133 descends and can drive the clamping parts 120 to move away from each other through the connecting rod assembly 140. The second vertical bracket 133 ascends and can drive the clamping parts 120 to move closer to each other through the connecting rod assembly 140 to clamp the flange 200.

[0076] In the embodiment of the present application, the lifting of the second vertical bracket 133 can be used to drive the clamping part 120 to slide in the horizontal direction X, so as to clamp or release the flange 200. Specifically, the upward movement of the second vertical bracket 133 along the vertical direction Y can drive the multiple clamping parts 120 to approach each other along the horizontal direction X to clamp the flange 200. During the entire lifting process, the second vertical bracket 133 can maintain the upward movement under the action of the lifting equipment, so that the clamping part 120 can maintain the state of clamping the flange 200, thereby improving the connection reliability between the clamping part 120 and the flange 200 and reducing safety hazards.

[0077] In the embodiment of the present application, the second vertical bracket 133 can be raised and lowered to drive the clamping part 120 to clamp or release the flange 200. Therefore, no additional mounting holes need to be drilled on the flange 200, and the staff does not need to manually connect the flange 200 to the clamping part 120, which is conducive to realizing automation in the hoisting process, saving manpower, and reducing labor costs, material costs, and processing costs.

[0078] Furthermore, since the distances between the plurality of clamping portions 120 are adjustable, the hoisting device 100 according to the embodiment of the present application can be applicable to flanges 200 of various sizes and specifications, which is beneficial to improving the versatility of the hoisting device 100 .

[0079] In addition, since the connecting rod assembly 140 is a rigid structure, the second vertical bracket 133 and the clamping part 120 can be rigidly connected through the connecting rod assembly 140, so the connecting rod assembly 140 can drive the clamping part 120 to slide along the horizontal direction X. Sliding along the horizontal direction X includes moving in a direction close to the flange 200 in the horizontal direction X, and also includes moving in a direction away from the flange 200 in the horizontal direction X, so that the connecting rod assembly 140 can drive the clamping parts 120 to approach each other to clamp the flange 200, and can also drive the clamping parts 120 to move away from each other to release the flange 200.

[0080] Furthermore, due to the force transmission coordination between the components of the connecting rod assembly 140 , it is beneficial to ensure that the clamping part 120 moves smoothly along the horizontal direction X under the action of the connecting rod assembly 140 , thereby preventing the clamping part 120 from getting stuck.

[0081] In some examples, the number of the connecting rod assemblies 140 can match the number of the clamping parts 120. One set of connecting rod assemblies 140 can be used to drive one clamping part 120 to slide along the horizontal direction X.

[0082] In some examples, the first vertical bracket 131 may be located at the center of the horizontal bracket 110. When the number of the clamping parts 120 is two, the number of the connecting rod assemblies 140 is two groups. The two groups of connecting rod assemblies 140 and the two clamping parts 120 may be symmetrically distributed on both sides of the first vertical bracket 131 relative to the first vertical bracket 131.

[0083] It should be noted that the embodiment of the present application does not limit the number of connecting rod assemblies 140 and the number of clamping parts 120.

[0084] In some examples, the horizontal bracket 110 may be provided with a slide rail for the clamping portion 120 to slide and connect. Part of the clamping portion 120 may slide in the slide rail, or the clamping portion 120 may slide in the slide rail through a transition structure to achieve movement of the clamping portion 120 along the horizontal direction X.

[0085] In other examples, a slide groove may be provided on the horizontal bracket 110. Part of the clamping portion 120 may slide in the slide groove, or the clamping portion 120 may slide in the slide groove through a transition structure to achieve movement of the clamping portion 120 along the horizontal direction X, which is not limited in this embodiment.

[0086] In some examples, the connecting rod assembly 140 can be formed by a plurality of rod bodies being fixedly or rotatably connected. Alternatively, the connecting rod assembly 140 can also include a transmission structure. For example, a worm and a gear cooperate with each other. The forward or reverse rotation of the worm can drive the gear to rotate, and the rotation of the gear drives the clamping portion 120 to move in a direction close to or away from the flange 200.

[0087] In some possible implementations, see Figure 1 and Figure 6 As shown, the connecting rod assembly 140 may include a first rod body 141 and a second rod body 142 connected to each other. One end of the first rod body 141 is rotatably connected to the second vertical bracket 133. The other end of the first rod body 141 is rotatably connected to the clamping portion 120. One end of the second rod body 142 is rotatably connected to the first rod body 141. The other end of the second rod body 142 is rotatably connected to the horizontal bracket 110.

[0088] In the embodiment of the present application, since the first rod 141 and the second rod 142 are rigid structures, the first rod 141 can push the clamping portion 120 to slide along the horizontal direction X through the coordinated movement of the first rod 141 and the second rod 142. In other words, the first rod 141 can drive the clamping portions 120 to move closer to each other, or drive the clamping portions 120 to move away from each other.

[0089] Furthermore, the first rod 141 and the second rod 142 can be used to transfer the load during the lifting process of the lifting device 100 , so as to keep the clamping part 120 moving along the horizontal direction X, thereby reducing the possibility of the clamping part 120 tilting.

[0090] It is easy to understand that the connection method between the first rod body 141 and the second rod body 142 is simple in structure, reliable, and easy to process and produce.

[0091] Specifically, when the second vertical bracket 133 moves upward, the end of the first rod 141 connected to the second vertical bracket 133 can move away from the center of the horizontal bracket 110 along the vertical direction Y, so that the end of the first rod 141 connected to the clamping portion 120 can move toward the center of the horizontal bracket 110 along the horizontal direction X, so that the clamping portions 120 can move closer to each other. When the second vertical bracket 133 moves downward, the end of the first rod 141 connected to the second vertical bracket 133 can move toward the center of the horizontal bracket 110 along the vertical direction Y, so that the end of the first rod 141 connected to the clamping portion 120 can move away from the center of the horizontal bracket 110 along the horizontal direction X, so that the clamping portions 120 can move away from each other.

[0092] In some practicable embodiments, the horizontal bracket 110 may be provided with a horizontal sliding groove 111 a to which the clamping portion 120 can be slidably connected.

[0093] In the embodiment of the present application, the horizontal slide groove 111 a can be provided to provide a guiding function for the clamping portion 120 , so that the clamping portion 120 can slide in the horizontal slide groove 111 a along the horizontal direction.

[0094] In some examples, the clamping portion 120 may slide in the horizontal slide groove 111a via the slider 121. For example, the slider 121 and the clamping portion 120 may be an integral structure.

[0095] In some examples, the first rod 141 may be connected to the slider 121 via a rotating shaft to drive the clamping portion 120 to slide along the horizontal direction X. Exemplarily, the slider 121 may slide in the horizontal slide groove 111a via a rotating shaft. The size of the rotating shaft may match the size of the horizontal slide groove 111a.

[0096] In some examples, the specific structure of the clamping portion 120 is not limited in this embodiment. The surface of the clamping portion 120 and the flange 200 that are in contact with each other can match the structure of the clamped portion of the flange 200. For example, the surface of the clamping portion 120 facing the flange 200 can be a curved surface, a V-shaped clamping surface, a flat surface, etc., which is not limited in this embodiment.

[0097] In some practicable embodiments, the horizontal support 110 may include a plurality of horizontal arms 111, and one end of each of the horizontal arms 111 may be connected to the first vertical support 131. The horizontal slide groove 111a may be disposed on the horizontal arm 111.

[0098] See also Figure 7 As shown, when the horizontal support 110 includes two horizontal arms 111, the horizontal support 110 may be in a straight line shape. The two clamping portions 120 may be arranged opposite to each other to clamp components such as cylinders and steel coils.

[0099] See also Figures 8 to 11 As shown, when the horizontal support 110 includes three, four, five, six or more horizontal arms 111, the plurality of clamping portions 120 can be used to clamp circular parts such as flanges 200 and thick blind plates.

[0100] It is easy to understand that the greater the number of horizontal brackets 110 , the better the clamping stability effect on the clamping flange 200 , so as to be used for clamping flanges 200 with larger mass.

[0101] In some possible implementations, see Fig.12 As shown, the clamping portion 120 may be provided with a horizontal placement surface 120a and a lateral clamping surface 120b. A clamping space for accommodating a portion of the flange 200 is formed between the horizontal placement surface 120a and the lateral clamping surface 120b.

[0102] Along the vertical direction Y, the size of the clamping space can be set larger to meet the needs of clamping a thicker flange 200 .

[0103] In some examples, when the flange 200 is a thick blind plate-like component, the horizontal placement surface 120a can be connected to the bottom surface of the flange 200 to support the flange 200. Alternatively, when the thickness of the flange 200 is relatively large, a clamping groove can be provided on the circumferential outer wall of the flange 200. The clamping groove can be used to provide a clamping point for the clamping portion 120.

[0104] In some examples, along the horizontal direction X, the size of the horizontal placement surface 120 a may satisfy the depth of the slot on the conventional flange 200 . The depth of the slot may refer to the size along the horizontal direction X.

[0105] Exemplarily, the size of the horizontal placement surface 120 a can be set to 50 mm to meet the requirements of flanges 200 of most specifications and sizes, thereby improving the versatility of the lifting device 100 .

[0106] In some possible implementations, see Figure 1 and Figure 6 As shown, the second vertical bracket 133 may be provided with an adjustment hook 132. The first vertical bracket 131 is provided with a clamping portion 1311 for the adjustment hook 132 to be clamped, and the first vertical bracket 131 is provided with a disengaging portion 1312 for the adjustment hook 132 to be disengaged from the clamping portion 1311.

[0107] In the embodiment of the present application, the process of the lifting device 100 clamping the flange 200 can be as follows.

[0108] First, see Figure 1 As shown, the second vertical bracket 133 moves downward along the vertical direction Y to drive the plurality of clamping parts 120 to move away from each other through the connecting rod assembly 140, so that the distance between the clamping parts 120 can be greater than the size of the flange 200. At this time, the adjustment hook 132 also moves downward under the action of the second vertical bracket 133, and the adjustment hook 132 can be engaged with the engaging part 1311, so that the distance between the clamping parts 120 can remain unchanged.

[0109] Specifically, by providing the engaging portion 1311 on the first vertical bracket 131, the adjustment hook 132 can be engaged with the engaging portion 1311. Since the adjustment hook 132 is engaged with the engaging portion 1311, the second vertical bracket 133 is not easy to move upward, resulting in a decrease in the distance between the plurality of clamping portions 120, and the clamping portions 120 can remain stationary relative to the horizontal bracket 110, so that during the process of the clamping portions 120 corresponding to the flange 200, the possibility of the clamping portions 120 being close to each other, resulting in the distance between the clamping portions 120 being smaller than the size of the flange 200, and the possibility of the clamping portions 120 being difficult to correspond to the flange 200 can be reduced.

[0110] Secondly, move the hoisting device 100 to a position where the clamping portion 120 corresponds to the flange 200. For example, the flange 200 can be placed on a workbench, and the hoisting device 100 can be located in the space above the flange 200. The second vertical bracket 133 can be moved upward to drive the multiple clamping portions 120 to approach each other to clamp the flange 200. However, since the adjustment hook 132 is engaged with the engagement portion 1311 and cannot move upward during the process of the clamping portion 120 corresponding to the flange 200, the disengagement portion 1312 can be provided on the first vertical bracket 131 in the embodiment of the present application to disengage the adjustment hook 132 from the engagement portion 1311, so that the second vertical bracket 133 can move upward, and the clamping portions 120 can be driven to approach each other to clamp the flange 200 through the connecting rod assembly 140.

[0111] It is easy to understand that applying a continuous upward force to the second vertical bracket 133 can keep the clamping parts 120 close to each other, thereby improving the clamping force of the clamping part 120 on the flange 200, improving the connection reliability between the clamping part 120 and the flange 200, and avoiding the flange 200 falling off and causing safety hazards.

[0112] When the lifting device 100 moves the flange 200 to the target workstation, the flange 200 can be dropped at the target workstation. At this time, the second vertical bracket 133 can be moved downward to drive the multiple clamping parts 120 to move away from each other through the connecting rod assembly 140, so that the clamping parts 120 can release the clamping force on the flange 200. The clamping parts 120 and the flange 200 can move away from each other. The lifting device 100 can continue to perform the next set of handling processes.

[0113] In some possible implementations, see Figures 2 to 4 As shown, the unhooking portion 1312 of the embodiment of the present application is slidably connected to the first vertical bracket 131 along the vertical direction Y, so that the unhooking portion 1312 has a first position and a second position.

[0114] Among them, see Figure 1 As shown, when the adjustment hook 132 is located at the engaging portion 1311, the unhooking portion 1312 is located at the first position, and there is a vertical gap between the unhooking portion 1312 and the engaging portion 1311. In addition, the adjustment hook 132 can drive the unhooking portion 1312 to slide, so that when the unhooking portion 1312 is located at the second position, the unhooking portion 1312 is connected to the engaging portion 1311.

[0115] In the embodiment of the present application, when the adjustment hook 132 is hooked with the engaging portion 1311, the unhooking portion 1312 is located at the first position. In other words, the unhooking portion 1312 can fall on the horizontal bracket 110 under the action of its own gravity. Under the action of the engaging portion 1311, the adjustment hook 132 causes the second vertical bracket 133 to be unable to move upward. At this time, the adjustment hook 132 can move downward to disengage from the engaging portion 1311. The vertical gap between the unhooking portion 1312 and the engaging portion 1311 can provide space for the adjustment hook 132 to move downward.

[0116] See also Figure 3 and Figure 4 As shown, when the adjustment hook 132 moves downward to connect with the unhooking portion 1312, the second vertical bracket 133 can drive the adjustment hook 132 to move upward. The adjustment hook 132 can hook the side wall of the unhooking portion 1312 to make the unhooking portion 1312 move upward for a distance. It is easy to understand that the distance that the adjustment hook 132 drives the unhooking portion 1312 to move upward can refer to the above-mentioned vertical gap. When the adjustment hook 132 moves upward to connect with the unhooking portion 1312 and the engaging portion 1311, the unhooking portion 1312 can make it difficult for the adjustment hook 132 to hook on the engaging portion 1311 again during the upward movement, so that the second vertical bracket 133 can continue to move upward, thereby achieving the mutual approach between the clamping portions 120 and locking the flange 200.

[0117] In some possible implementations, see Figure 4 As shown, the engaging portion 1311 of the embodiment of the present application may be provided with an engaging surface 1311a facing the horizontal bracket 110. The adjusting hook 132 is hooked with the engaging surface 1311a to fix the clamping portion 120. Moreover, when the unhooking portion 1312 is located at the second position, the unhooking portion 1312 is in contact with the engaging surface 1311a.

[0118] In an embodiment of the present application, when the adjustment hook 132 moves downward to the locking surface 1311a of the locking portion 1311 facing the horizontal bracket 110, the adjustment hook 132 can hook onto the locking surface 1311a, so that the adjustment hook 132 is not easy to move upward, thereby making it difficult for the clamping portions 120 to get close to each other, and thus the distance between the clamping portions 120 can be kept greater than the size of the flange 200.

[0119] When the flange 200 needs to be clamped, the second vertical bracket 133 can be used to drive the adjustment hook 132 to move downward to connect with the unhooking portion 1312. Then, the second vertical bracket 133 moves upward so that the adjustment hook 132 can drive the unhooking portion 1312 to move upward. When the unhooking portion 1312 moves upward to fit with the engaging surface 1311a of the engaging portion 1311, the unhooking portion 1312 can shield the engaging surface 1311a, so that the adjustment hook 132 is not easy to be hooked on the engaging surface 1311a again during the upward movement of the adjustment hook 132, so that the second vertical bracket 133 can continue to move upward, and the clamping portion 120 can clamp the flange 200.

[0120] In some possible implementations, see Figure 4 As shown, the engaging surface 1311a of the embodiment of the present application is located on the side of the engaging portion 1311 facing the unhooking portion 1312. The unhooking portion 1312 has a fitting surface 1312a facing the engaging portion 1311. The outer contour size of the engaging surface 1311a is less than or equal to the outer contour size of the fitting surface 1312a.

[0121] In the embodiment of the present application, by setting the outer contour size of the engaging surface 1311a of the unhooking portion 1312 to be larger than the outer contour size of the fitting surface 1312a of the engaging portion 1311, the unhooking portion 1312 can completely cover the engaging portion 1311, so that during the upward movement of the adjusting hook 132, the adjusting hook 132 is not easy to contact the engaging surface 1311a, that is, the adjusting hook 132 is not easy to engage with the engaging surface 1311a, resulting in the inability of the adjusting hook 132 to move upward, thereby avoiding the phenomenon that the clamping portion 120 is difficult to lock the flange 200.

[0122] In some examples, the outer contour size of the locking surface 1311a can be equal to the outer contour size of the fitting surface 1312a, so that the adjustment hook 132 is not prone to fluctuation during the process of moving from the outer wall of the unhooking portion 1312 to the outer wall of the locking portion 1311, which is beneficial to reduce the impact of the fluctuation of the adjustment hook 132 on the clamping force of the clamping flange 200 of the clamping portion 120.

[0123] In some examples, the engaging surface 1311a may be, but is not limited to, a plane. For example, the middle area of ​​the engaging surface 1311a may be recessed in the direction of the first vertical bracket 131. Part of the adjustment hook 132 may be located in the recessed area of ​​the engaging surface 1311a to improve the connection reliability between the adjustment hook 132 and the engaging surface 1311a. In addition, the recessed area of ​​the engaging surface 1311a may also be used to accommodate impurities to reduce the possibility that impurities enter between the engaging surface 1311a and the fitting surface 1312a, causing the two to be difficult to fit and produce a gap, thereby causing the adjustment hook 132 to hook with the engaging surface 1311a again and the adjustment hook 132 to be unable to move upward.

[0124] In some possible implementations, see Figures 2 to 4 As shown, the outer wall of the unhooking portion 1312 of the embodiment of the present application is provided with an inclined wall surface 1312b. Along the vertical direction Y upward, the cross-sectional dimension of the unhooking portion 1312 gradually increases. The cross-sectional dimension is perpendicular to the vertical direction Y.

[0125] In the embodiment of the present application, the adjusting hook 132 can drive the unhooking portion 1312 to move upward until it is connected to the engaging portion 1311 by hooking and clamping the inclined wall surface 1312b. In addition, since the cross-sectional size of the unhooking portion 1312 gradually increases upward along the vertical direction Y, the inclined wall surface 1312b can also provide a guiding function for the adjusting hook 132 to move upward. The adjusting hook 132 can move upward along the inclined wall surface 1312b.

[0126] In some examples, the unhooking portion 1312 may be sleeved on an outer wall of the first vertical bracket 131 to slide up and down along the first vertical bracket 131 .

[0127] In some possible ways, see Figures 2 to 4 As shown, the outer wall of the engaging portion 1311 of the embodiment of the present application is provided with a buffer surface 1311b. The adjusting hook 132 can move along the buffer surface 1311b to the first vertical bracket 131. Along the vertical direction Y upward, the cross-sectional size of the unhooking portion 1312 gradually decreases.

[0128] In the embodiment of the present application, the buffer surface 1311b can make the adjustment hook 132 slowly disengage from the locking portion 1311 to avoid jamming or vibration of the adjustment hook 132 during the movement from the locking portion 1311 to the first vertical bracket 131, thereby affecting the clamping effect between the clamping portions 120 and affecting the connection reliability between the clamping portions 120 and the flange 200.

[0129] For some examples, see Figure 6 and Fig.13 As shown, the lifting device 100 may include a fixing assembly 150. The fixing assembly 150 may include a lifting ring 151 and an upper sealing plate 152. The lifting ring 151 may be arranged on the upper sealing plate 152. The lifting ring 151 may be connected to a lifting hook of the lifting device through a shackle sling. The second vertical bracket 133 is fixedly connected to the upper sealing plate 152.

[0130] For some examples, see Figure 6 and Fig.14 As shown, the inner wall of the first vertical bracket 131 may be provided with a first guide ring 134. The outer wall of the second vertical bracket 133 may be provided with a second guide ring 135. The first guide ring 134 and the second guide ring 135 may be provided to provide a guide function for the vertical movement of the second vertical bracket 133, so as to maintain the stability of the second vertical bracket 133 during the up and down movement.

[0131] In some examples, the first guide ring 134 and the second guide ring 135 may be made of a buffer material such as rubber to reduce the possibility of abnormal noise caused by collision during the relative movement between the first guide ring 134 and the second guide ring 135 .

[0132] In some examples, the fixing assembly 150 may further include a fixing ear plate 153. The fixing ear plate 153 may be disposed on the upper sealing plate 152, and the fixing ear plate 153 and the hanging ring 151 are located on both sides of the upper sealing plate 152. The first rod body 141 may be connected to the fixing ear plate 153 via a rotating shaft. The first rod body 141 and the second rod body 142 may be connected via a rotating shaft. The first rod body 141 and the clamping portion 120 may also be connected via a rotating shaft.

[0133] Exemplarily, the number of the fixing lug plates 153 may be multiple groups. Each group of fixing lug plates 153 may include two fixing lug plates 153. A group of fixing lug plates 153 may be used to fix a group of connecting rod assemblies 140. For example, the first rod body 141 may be located between the two fixing lug plates 153.

[0134] The distance between the two fixing ear plates 153 and the thickness of the first rod body 141 can satisfy the installation gap. For example, the installation gap can be 1 mm to 2 mm.

[0135] In some examples, the fixing assembly 150 may further include an adjusting hook plate 154. The adjusting hook plate 154 may be disposed on the second vertical bracket 133. The adjusting hook 132 may be fixed to the second vertical bracket 133 via the adjusting hook plate 154.

[0136] In some examples, the adjustment hook 132 may include a plurality of hooks 1321. One end of the hook 1321 may be connected to the adjustment hook ear plate 154, and the other end of the hook 1321 may be used to hook the buckle engaging portion 1311.

[0137] Exemplarily, there may be multiple groups of adjusting hook plates 154. One group of adjusting hook plates 154 may correspond to one hook 1321. Each group of adjusting hook plates 154 may include two adjusting hook plates 154. For example, one end of the hook 1321 may be located between the two adjusting hook plates 154.
