Description

Technical Field

[0001] The present application belongs to the technical field of lifting tools, and specifically relates to a lifting tool, lifting equipment and lifting method. Background Art

[0002] Highly flexible couplings are widely used in fields such as marine power systems due to their wide stiffness adjustment range and high displacement compensation capabilities. As the main component of a highly flexible coupling, the sector block is primarily composed of upper and lower sector-shaped metal flanges and rubber vulcanization.

[0003] During the hoisting and movement of a sector block, it is necessary to install lifting rings or shackles on the flange holes of the sector block. The lifting rings or shackles are then hoisted with equipment, keeping the sector block in a nearly vertical position during lifting. Sector blocks are typically stored horizontally, with the sector surface of the sector metal flange parallel to the load-bearing surface. When the sector block needs to be mounted horizontally on a workpiece, tools such as slings are required to tie and hoist the sector block to maintain its horizontal position, making hoisting and horizontal installation inefficient.

[0055] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described are only 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 those skilled in the art without making creative efforts are within the scope of protection of this application.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, and at least one means one, two or more, unless otherwise clearly and specifically defined.

[0057] An embodiment of the present application discloses a lifting tool.

[0058] Example 1:

[0059] Reference Figure 1 A lifting tool 1 includes a lifting body 10 and a supporting body 11. It should be noted that, referring to Figure 2 In this embodiment, a part to be hoisted 3 is introduced to demonstrate the use of the hoisting tool 1. The part to be hoisted 3 can be a highly elastic coupling sector block. When placed horizontally, it is mainly composed of upper and lower sector-shaped metal flanges and rubber vulcanization, that is, Figure 2 In addition to the structure of the part to be hoisted shown in the figure, the part to be hoisted 3 can also be other components that are spaced and combined with two or more flange structures or perforated plate structures. No more details are given here. Therefore, in the following text, the part to be hoisted 3 includes a hoisting part 30a and a pressure-bearing part 30b, which is actually Figure 2 The flange structure is shown.

[0060] The hoisting body 10 includes a hoisting member 100 and a hooking member 101. The hoisting member 100 is arranged horizontally above the center of gravity of the object to be hoisted 3. The left end of the hoisting member 100 is provided with a hooking portion 10000 for connection with the hook 20 of the hoisting device 2 (refer to FIG. Figure 13), the hooking part 10000 in this embodiment is a hanging hole structure, and in other embodiments, structures such as hanging rings and lock buckles can also be used, which will not be repeated here; the hooking part 101 is connected to the bottom of the right end of the hanging part 100, and the lower end of the hooking part 101 extends between the hanging part 30a and the pressure-bearing part 30b of the part to be hung. During the lifting process, the hooking part 101 supports the bottom surface of the hanging part 30a and hooks the corresponding flange hole 300. During the lifting process of the part to be hung 3, the operator can try to place the hanging part 100 horizontally to coincide with the radial line of the center of gravity of the part to be hung 3, and mainly estimate the center of gravity based on its specifications, which is conducive to making the force on the part to be hung 3 more stable during the lifting process.

[0061] The supporting body 11 includes a guide member 110 fixedly connected to the hook member 101 on the side away from the part to be hung 3, and a support member 111 slidably adjusted and arranged on the side of the guide member 110 away from the hook member 101. During the process of hoisting the part to be hung 3, after the hook member 101 supports the hoisting portion 30a and hooks the flange hole 300, the support member 111 slides and adjusts along the guide member 110 until it is supported on the top surface of the pressure-bearing portion 30b, so that the part to be hung 3 is subjected to force and forms a tendency to reverse to the upper left as a whole. The hook member 101 cooperates with the support member 111 to clamp the part to be hung 3, and at the same time, the hook 20 of the lifting device 2 lifts the entire part to be hung 3 upward from the left end of the lifting member 100, so that the part to be hung 3 remains in a horizontal state during the overall suspension process, which is conducive to rapid horizontal hoisting and installation of the part to be hung 3.

[0062] Specifically, refer to Figures 1 to 3 The hanging part 100 includes a hanging part 1000 and a main body 1001. The hanging part 1000 can be made of steel plate. The hook part 10000 is opened through the left end of the hanging part 1000. The right end of the hanging part 1000 is opened along its own length direction in sequence through a plurality of first pin holes 10001. In this embodiment, three first pin holes 10001 are taken as an example.

[0063] The main body 1001 is positioned to the right of the hanging portion 1000. Two ribs 10011 are fixedly connected to the left end of the main body 1001. The two ribs 10011 are spaced apart and formed with a clamping groove 10012. The portion of the hanging portion 1000 where the first pin hole 10001 is located extends into the clamping groove 10012. A plurality of second pin holes 10010 are sequentially formed along the length of each rib 10011. In this embodiment, the number of second pin holes 10010 on a single rib 10011 corresponds to the number of first pin holes 10001, i.e., three. After the hanging part 1000 extends into the clamping groove 10012, each first pin hole 10001 is aligned with a pair of second pin holes 10010 and is penetrated by a pin 1002, that is, the main body 1001 and the hanging part 1000 are fixedly connected by the cooperation of multiple second pin holes 10010, the pin 1002 and the first pin hole 10001.

[0064] It should be noted that, in other embodiments, the lengths of the hanging portion 1000, the main body 1001 and the rib plate 10011 thereof can be adjusted according to the size and weight of the part 3 to be hung, thereby increasing or decreasing the number of the first pin holes 10001 and the second pin holes 10010, thereby adjusting the length of the hanging portion 1000 extending into the clamping groove 10012, and ensuring that at least two first pin holes 10001 are connected one by one to the two pairs of second pin holes 10010 through the pin 1002.

[0065] Reference Figure 1 and Figure 2 The hooking member 101 includes a connecting portion 1010, a supporting portion 1011 and a first hook head 1012. The connecting portion 1010 can be made of round steel, and the top of the connecting portion 1010 is connected to the bottom surface of the main body 1001. It should be noted that the connecting portion 1010 and the main body 1001 can be rotatably connected, that is, the connecting portion 1010 can rotate around its own axis, or can be fixedly connected to the main body 1001. At the same time, the connecting portion 1010 can be set as a single one, or two or more can be set. It can be understood that when multiple connecting portions 1010 are set, the size of the main body 1001 needs to be increased and adaptively arranged to match the distribution of the flange holes 300 on the hanging component 3. The supporting portion 1011 and the first hook head 1012 also increase or decrease with the number of connecting portions 1010.

[0066] In this embodiment, the guide member 110 is assembled on the connecting portion 1010, and taking two connecting portions 1010 as an example, this embodiment takes the connecting portion 1010 fixedly connected to the main body 1001 as an example. In other embodiments, the supporting body 11 can be fixed at a position such as the right end of the main body 1001. At this time, the connecting portion 1010 can be rotated to connect to the main body 1001.

[0067] The bottom end of the connecting portion 1010 extends toward between the hoisting portion 30a and the pressure-bearing portion 30b of the component 3 to be hoisted, and the supporting portion 1011 is connected to the bottom end of the connecting portion 1010. During use of the hoisting tool 1, the supporting portion 1011 is used to extend between the hoisting portion 30a and the pressure-bearing portion 30b and support the bottom surface of the hoisting portion 30a. The first hook 1012 is fixed to the top surface of the supporting portion 1011 at one end away from the connecting portion 1010. It is understood that in some embodiments, when the connecting portion 1010 can rotate around its own axis, the supporting portion 1011 can be rotatably connected to the connecting portion 1010, or it can be fixedly connected to the connecting portion 1010. In this case, the first hook 1012 can be rotated around the axis of the connecting portion 1010 to adapt to the position distribution of the flange hole 300. In this embodiment, the supporting portion 1011 is rotatably connected to the connecting portion 1010 , and the top surface of the supporting portion 1011 remains parallel to the plane of the hanging portion 30a, ensuring that the first hook head 1012 can rotate around the axis of the connecting portion 1010 to adjust the position and adapt to the flange hole 300 .

[0068] It can be understood that the first hook head 1012 is a column as a whole that is adapted to the flange hole 300 structure, and its radial dimension can be smaller than the aperture of the flange hole 300, thereby improving the efficiency of the docking between the two. At the same time, the top end of the first hook head 1012 can be chamfered to further improve the convenience of inserting the first hook head 1012 into the corresponding flange hole 300.

[0069] Reference Figure 2 and Figure 3 , the support member 111 includes a sliding portion 1110 and a supporting portion 1111. The sliding portion 1110 can be a longitudinally extending plate, and the supporting portion 1111 is fixed to the bottom side of the sliding portion 1110. The sliding portion 1110 and the supporting portion 1111 can be integrally formed or welded. A sliding groove 1100 is provided on the side wall of the guide member 110 away from the connecting portion 1010. The sliding groove 1100 passes through the guide member 110 longitudinally and allows the sliding portion 1110 to slide between the hoisting portion 30a and the pressure-bearing portion 30b. It should be noted that, in this embodiment, the sliding portion 1110 is longitudinally divided into a vertically downward portion and a portion inclined toward the bottom of the connecting portion 1010 from top to bottom. The inclined portion of the sliding portion 1110 is intended to press the supporting portion 1111 against the top surface of the pressure-bearing portion 30b below during the downward sliding process. In other embodiments, the sliding portion 1110 can also be arranged as a whole to be tilted toward the lower end of the connecting portion 1010. In this case, the extension direction of the slide groove 1100 of the adjustment guide 110 can also be tilted toward the side of the connecting portion 1010. When the lifting tool 1 is in use, the support portion 1111 extends horizontally between the lifting portion 30a and the pressure-bearing portion 30b, supporting the top surface of the pressure-bearing portion 30b. At the same time, the bottom end of the sliding portion 1110 is in contact with the outer edge of the pressure-bearing portion 30b, thereby improving support stability.

[0070] The side wall of the sliding portion 1110 is provided with a plurality of first positioning holes 11100, and the plurality of first positioning holes 11100 are longitudinally distributed in sequence along the vertical downward part of the sliding portion 1110, and the two opposite side walls of the guide member 110 are respectively provided with second positioning holes 1101, and the second positioning holes 1101 pass through the connecting slide groove 1100, and at least two second positioning holes 1101 are arranged longitudinally, and each second positioning hole 1101 is penetrated by a positioning pin 112, and the positioning pin 112 is simultaneously inserted into the corresponding first positioning hole 11100 to fix the sliding portion 1110.

[0071] The implementation principle of Example 1 is as follows: the operator adjusts the overall length of the lifting part 1000 and the main body 1001 in advance according to the model and center of gravity distribution of the part to be lifted 3 to ensure that the hook part 10000 is located on the side of the center of gravity of the part to be lifted 3 away from the connecting part 1010, and then the hook 20 of the lifting device 2 is connected to the hook part 10000 to move the entire lifting tool 1 above the part to be lifted 3; the supporting part 1011 and the first hook head 1012 are pushed between the lifting part 30a and the pressure-bearing part 30b, and the supporting part 1011 is rotated to flexibly adjust the first hook head 1012 to align with the corresponding flange hole 300, so that The first hook head 1012 is inserted into the corresponding flange hole 300, and the supporting part 1011 supports the bottom surface of the lifting part 30a; the sliding part 1110 is adjusted along the slide groove 1100 until the supporting part 1111 supports the top surface of the pressure-bearing part 30b, and the supporting position of the supporting part 1111 is quickly fixed by the positioning pin 112, thereby completing the lifting work of the lifting tool 1 on the part to be lifted 3; then the lifting equipment 2 is driven upward to lift and move the part to be lifted 3 horizontally, avoiding the need to use more binding tools, supporting tools, etc. in the lifting work, thereby improving the lifting efficiency and the convenience of subsequent direct horizontal installation of the part to be lifted 3.

[0072] Example 2:

[0073] Reference Figure 4 and Figure 5 This embodiment differs from Embodiment 1 in that a second hook 1112 is fixedly connected to the bottom surface of the support portion 1111. It is understood that, in order to improve manufacturing efficiency and reduce costs, the structure of the support portion 1111 is identical to that of the support portion 1011, and the structure of the second hook 1112 is identical to that of the first hook 1012. That is, when the support portion 1111 is supported on the top surface of the pressure-bearing portion 30b, the second hook 1112 is inserted into the corresponding flange hole 300. It should be noted that, because the sliding portion 1110 is arranged with an inclined movement direction to ensure that the support portion 1111 abuts the top surface of the pressure-bearing portion 30b, the radial dimension of the second hook 1112 needs to be smaller than the diameter of the flange hole 300, and the axial dimension of the second hook 1112 needs to be adaptively shortened compared to the first hook 1012, thereby ensuring that the second hook 1112 can be smoothly inserted into the corresponding flange hole 300 when the support portion 1111 abuts the top surface of the pressure-bearing portion 30b.

[0074] Similarly, the support portion 1111 can be provided in a single or multiple configurations, and the corresponding second hooks 1112 increase or decrease with the number of support portions 1111. Simultaneously, the support portion 1111 rotates to connect to the bottom end of the sliding portion 1110, and the plane formed by the rotation of the support portion is parallel to the plane of the pressure-bearing portion 30b. At this time, the support portion 1111 can drive the second hook 1112 to rotate and adapt to its position relative to the flange hole 300.

[0075] The implementation principle of Example 2 is as follows: the operator pushes the supporting part 1011 and the first hook head 1012 between the hoisting part 30a and the pressure-bearing part 30b, rotates the supporting part 1011 and flexibly adjusts the first hook head 1012 to align with the corresponding flange hole 300, so that the first hook head 1012 is inserted into the corresponding flange hole 300 and the supporting part 1011 supports the bottom surface of the hoisting part 30a; adjusts the sliding part 1110 along the slide groove 1100, and rotates the supporting part 1111 to flexibly adjust the second hook head 1112 to align with the corresponding The flange hole 300 allows the support portion 1111 to support the top surface of the pressure-bearing portion 30b, and the second hook 1112 is inserted into the corresponding flange hole 300. The support position of the support portion 1111 is quickly fixed by the positioning pin 112, thereby completing the lifting work of the lifting tool 1 on the object to be lifted 3; then, the lifting device 2 is driven upward to lift the object to be lifted 3 horizontally and move it, avoiding the need for additional binding tools, supporting tools, etc. during the lifting work, improving the lifting efficiency and the convenience of subsequent direct horizontal installation of the object to be lifted 3. Compared with Example 1, the introduction of the structure of the second hook 1112 further improves the lifting stability of the object to be lifted 3 and reduces the risk of the pressure-bearing portion 30b detaching from the support portion 1111.

[0076] Example 3:

[0077] Reference Figures 6 to 8 This embodiment differs from the above-described embodiment in that a first guide groove 10110 is defined along the top surface of the supporting portion 1011 along its length for the sliding movement of the first hook 1012, and a second guide groove 11110 is defined along the bottom surface of the supporting portion 1111 along its length for the sliding movement of the second hook 1112. The first guide groove 10110 and the second guide groove 11110 can be configured as T-shaped grooves. Accordingly, a first guide block 10120 is fixedly connected to the bottom end of the first hook 1012 to accommodate the limiting structure of the first guide groove 10110, and a second guide block 11120 is fixedly connected to the top end of the second hook 1112 to accommodate the limiting structure of the second guide groove 11110. In other embodiments, the first guide groove 10110 and the second guide groove 11110 can be configured as other structures, such as dovetail grooves, which will not be described in detail here.

[0078] It should be noted that in other embodiments, it is also possible to define only the first guide groove 10110 on the supporting portion 1011 or only the second guide groove 11110 on the supporting portion 1111, and it is not necessary to ensure that both the first hook 1012 and the second hook 1112 can move. The direction of the guide groove can also be changed to flexibly adjust the positions of the first hook 1012 and the second hook 1112 to adapt to the corresponding flange hole 300.

[0079] The implementation principle of Example 3 is: It can be understood that through the introduction of the first guide groove 10110 and the second guide groove 11110, on the basis of the rotatable supporting part 1011 and the supporting part 1111, the moving range of the first hook head 1012 and the second hook head 1112 is further expanded, thereby improving the adaptability of the first hook head 1012 and the second hook head 1112 to the corresponding flange hole 300.

[0080] Example 4:

[0081] Reference Figures 9 to 12 This embodiment differs from the above-described embodiment in that a first receiving groove 10111 is defined on the supporting surface of the supporting portion 1011, and a second receiving groove 11111 is defined on the supporting surface of the support portion 1111. A first hinge axis 10121 is fixedly inserted through the bottom end of the first hook 1012. First reaming holes 10112 are defined on two opposing sidewalls of the first receiving groove 10111 at one end away from the connecting portion 1010. The first hook 1012 is hingedly connected to the corresponding first reaming holes 10112 via the two ends of the first hinge axis 10121.

[0082] On this basis, first torsion springs 10122 are sleeved around both ends of the first hinge shaft 10121. One end of the first torsion spring 10122 is fixedly connected to the first hinge shaft 10121, and the other end is fixedly connected to the wall of the first reamed hole 10112. The first torsion spring 10122 is designed to generate a torsional force to restore the first hook head 1012 to its original position when the external force disappears after the first hook head 1012 is rotated toward the first receiving slot 10111 by an external force. This is sufficient as long as the first hook head 1012 remains vertical and in contact with the side wall of one end of the first receiving slot 10111 in the absence of external force.

[0083] Similarly, a second hinge shaft 11121 is fixedly mounted on the top of the second hook 1112. A second reaming hole 11112 is defined on the sidewall of the second receiving slot 11111, at the end away from the sliding portion 1110. The second hook 1112 is hingedly connected to the corresponding second reaming hole 11112 via the ends of the second hinge shaft 11121, demonstrating the same hinge structure as the first hook 1012. A second torsion spring 11122 is sleeved on both ends of the second hinge shaft 11121. One end of the second torsion spring 11122 is fixedly connected to the second hinge shaft 11121, while the other end is fixedly connected to the wall of the second reaming hole 11112. The second torsion spring 11122 is intended to form a torsional force to restore the second hook head 1112 when the external force disappears after the second hook head 1112 is acted upon by an external force and turns to the second accommodating groove 11111. It is sufficient to ensure that the second hook head 1112 remains in a vertical state without the action of external force and fits against the side wall of one end of the second accommodating groove 11111.

[0084] It should be noted that, in other embodiments, it is also possible that only the first hook head 1012 is hinged to the supporting portion 1011 or only the second hook head 1112 is hinged to the supporting portion 1111. It is not necessary for both the first hook head 1012 and the second hook head 1112 to rotate at the same time.

[0085] The implementation principle of Example 4 is: when the operator pushes the supporting part 1011 and the first hook head 1012, the supporting part 1111 and the second hook head 1112 between the lifting part 30a and the pressure-bearing part 30b, the rotatable first hook head 1012 and the second hook head 1112 can be rotated into the corresponding first accommodating groove 10111 and the second accommodating groove 11111 when subjected to external force, thereby avoiding rigid collision with the structure of the part to be hung 3, and further improving the protection of the part to be hung 3 and the first hook head 1012 and the second hook head 1112 compared with Example 2.

[0086] The embodiment of the present application also discloses a lifting device 2.

[0087] Reference Figure 13 A lifting device 2 includes the above-mentioned lifting tool 1. This embodiment takes the lifting tool 1 of Example 1 as an example. In other embodiments, lifting tools 1 of different embodiments can be flexibly adapted as needed. The basic structure of the lifting device 2 can adopt a truss 22. A movable power device 21, such as an electric hoist, is provided at the top of the truss 22. The power device 21 lowers a hook 20 and hooks it to the hook portion 10000 of the corresponding lifting tool 1, thereby realizing rapid lifting of the part to be lifted 3, horizontal movement and installation of the part to be lifted 3, and improving the efficiency of horizontal movement and assembly of the part to be lifted 3.

[0088] The embodiment of the present application also discloses a lifting method using the lifting device 2, comprising the following steps:

[0089] The driving power device 21 is moved to above the object to be hoisted 3 , and the power device 21 is controlled to lower the hook 20 and connect the hook portion 10000 of the hoisting member 100 to the hook 20 of the hoisting device 2 ;

[0090] Insert the hooking member 101 between the hanging portion 30a and the pressure-bearing portion 30b, so that the hooking member 101 supports the plane of the hanging portion 30a and hooks the corresponding flange hole 300;

[0091] Adjust the support member 111 along the guide member 110 toward the pressure-bearing portion 30 b so that the support member 111 supports the plane of the pressure-bearing portion 30 b ;

[0092] The driving power device 21 pulls up the hook 20 to lift the object 3 to be hoisted horizontally, and then the driving power device 21 moves along the truss 22 to drive the object 3 to be hoisted to move horizontally to the target position.
