[0002] Ships, vehicles that sail or anchor in water for transportation or underwater operations, have varying technical performance, equipment, and structural forms depending on their specific needs. Typically, ships have a streamlined exterior to overcome fluid resistance, and their materials have evolved from natural materials like wood, bamboo, and hemp to modern composite materials like steel, aluminum, fiberglass, and acrylic. To ensure ships remain in good condition, regular maintenance and repairs are essential, and they also require regular inspections by ship inspection agencies. This requires the use of auxiliary support equipment for lifting. Existing auxiliary support equipment often uses large gantry cranes for lifting ships, facilitating manufacturing and maintenance. However, these conventional lifting devices lack structural rigidity, making them prone to excessive vessel movement during the lifting process. The lifting ropes are also prone to wear and breakage, and lack adaptive guide structures, which can lead to collision damage between the hoisted objects and other structures. Therefore, ensuring stable lifting during manufacturing and maintenance, preventing movement and collision damage, and minimizing wear and breakage of the lifting ropes, remains a challenge currently facing researchers in this field.

[0038] The technical solution of this embodiment will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0039] like Figures 1-8 As shown, this embodiment provides a lifting auxiliary device, two lifting auxiliary devices are arranged facing each other, the lifting auxiliary devices include several ropes 100, a support platform 10, a lifting component 20 and an auxiliary component 30, one end of the rope 100 is wrapped around one side of the support platform 10, and the other end is connected to the lifting component 20, and the lifting component 20 is located on the other side of the support platform 10. When the rope 100 is wound in the support platform 10, the lifting component 20 moves along the first direction for ship lifting; the auxiliary component 30 and the lifting component 20 are arranged on the same side, and the auxiliary component 30 is slidably arranged on the support platform 10 along the second direction, and several auxiliary rollers 33 are obliquely arranged on the auxiliary component 30. The auxiliary components 30 of the two lifting auxiliary devices are arranged facing each other, and the auxiliary rollers 33 on the two groups of auxiliary components 30 can provide support for the ship.

[0040] Specifically, this embodiment utilizes two opposing lifting assist devices to simultaneously and stably lift both sides of a ship during ship manufacturing or maintenance, ensuring stable lifting of the ship. Furthermore, each lifting assist device is equipped with multiple ropes 100 connected to a lifting assembly 20. These ropes are wound around a support platform 10, driving the lifting assembly 20 to move in a first direction, thereby lifting the ship. The multiple ropes 100 provide multiple traction paths to ensure stable lifting and lowering of the ship, preventing wear and breakage of the ropes 100. At the same time, in this embodiment, the auxiliary component 30 is slidably arranged on the support platform 10, and a number of auxiliary rollers 33 are obliquely arranged on the auxiliary component 30. Therefore, under the support of the auxiliary rollers 33 of the two groups of auxiliary components 30 in the two oppositely arranged lifting auxiliary devices, the stable support of the bottom of the ship can be guaranteed, and since the position of the auxiliary component 30 is adjustable, it can be suitable for ships of different sizes, and the position can be adjusted according to the position of the ship to provide dynamic support, ensuring that the ship will not shake after lifting, thereby avoiding collision damage accidents and realizing stable lifting during ship production and maintenance.

[0041] The specific structure of the lifting auxiliary device in this embodiment is described below.

[0042] like Figure 1-Figure 4As shown, in this embodiment, when using the lifting auxiliary device to lift and assist in supporting the ship during production, the two lifting auxiliary devices can be set facing each other to improve the stability of the ship during the lifting process and provide auxiliary support on both sides of the ship at the same time. For example, the lifting auxiliary device in this embodiment can be used alone to lift the ship, or it can be used in conjunction with a traditional lifting device to provide auxiliary lifting and ensure stable lifting of the ship. The specific selection can be made according to actual needs. Specifically, the lifting auxiliary device in this embodiment includes a support platform 10, a lifting component 20 and an auxiliary component 30, and is provided with a rope 100. Optionally, several ropes 100 are provided, and one end of the rope 100 is wound around one side of the support platform 10 and can be reeled in the support platform 10. The other end of the rope 100 is connected to the lifting assembly 20, and the lifting assembly 20 is located on the other side of the support platform 10. Thus, through the reeling operation of several ropes 100 on the support platform 10, the lifting assembly 20 can be driven to move in the first direction so as to lift the ship, and the provision of multiple ropes 100 can effectively ensure the stable movement of the lifting assembly 20 and ensure stable lifting of the ship.

[0043] Furthermore, in this embodiment, the auxiliary assembly 30 and the lifting assembly 20 are arranged on the same side, and when the two lifting auxiliary devices are arranged facing each other, the corresponding two sets of auxiliary assemblies 30 are also arranged facing each other to provide stable auxiliary support for both sides of the vessel. Specifically, the auxiliary assembly 30 is slidably arranged on the support platform 10 along the second direction, and a number of auxiliary rollers 33 are tilted and arranged on the auxiliary assembly 30. Under the arrangement of the auxiliary rollers 33 of the two sets of auxiliary assemblies 30, the vessel can achieve dynamic and stable support, ensuring that the vessel will not shake and damage the lifting equipment during the production process. At the same time, because the position of the auxiliary assembly 30 is adjustable, it is suitable for vessels of different sizes. For example, in this embodiment, several ropes 100 are arranged parallel and spaced apart along the third direction. Correspondingly, the auxiliary rollers 33 are also extended along the third direction, and the several auxiliary rollers 33 are arranged parallel and spaced apart on the auxiliary assembly 30. Specifically, the first direction, the second direction, and the third direction are all perpendicular to each other.

[0044] like Figure 1-Figure 7 As shown, in this embodiment, the support platform 10 includes a base 11, a winding assembly 12, a diagonal support 13 and a top support 14, and the winding assembly 12 and the diagonal support 13 are respectively located on both sides of the base 11, and the top support 14 is connected to the diagonal support 13. One end of the rope 100 is wound around the winding assembly 12 and can be wound at the winding assembly 12. The other end of the rope 100 is guided by the top support 14 and connected to the lifting assembly 20. When the winding assembly 12 retracts and releases the rope 100, the lifting assembly 20 drives the ship to which it is hooked to move up and down along the first direction to realize the lifting operation of the ship.

[0045] like Figure 6 and Figure 7 As shown, in this embodiment, the base 11 is provided with an extension plate 111 extending along the second direction, and a receiving groove 101 is provided in the base 11, and a slide groove 102 is provided on the extension plate 111. Optionally, the receiving groove 101 is provided along the second direction, and the opening is provided toward the extension plate 111, for connecting the auxiliary component 30. Furthermore, a slide groove 102 is provided on the extension plate 111, and the auxiliary component 30 is slidably provided in the slide groove 102. Exemplarily, the slide groove 102 is provided as a T-slot, and the T-slot passes through the center of the extension plate 111. Specifically, the width of the upper notch of the slide groove 102 along the third direction is smaller than the width of the lower notch of the slide groove 102 along the third direction, thereby limiting and guiding the auxiliary component 30, preventing the auxiliary component 30 from detaching from the base 11 during the sliding process, and ensuring that the sliding direction is always in the second direction, so as to provide stable dynamic support for the ship.

[0046] Furthermore, in this embodiment, the winding assembly 12 includes a mounting seat, a first driving mechanism 124, a rotating shaft 125, a winding drum 126, a first pulley 127 and a limiting roller 128, and the mounting seat includes an inclined rod 121, a first connecting plate 122 and a support plate 123. Specifically, the mounting seat is a triangular structure to improve structural stability, and the two inclined rods 121 are arranged to be inclined toward each other, and the bottom ends of the two inclined rods 121 are connected to the base 11, and the top ends are connected to form a mounting plate through the first connecting plate 122. The two mounting plates are symmetrically arranged on the base 11 and connected by the support plate 123 fixed on the top side to form a mounting seat. Optionally, the rotating shaft 125 is rotatably arranged in the mounting seat, and the first driving mechanism 124 is connected to the rotating shaft 125 to serve as a power source for the rotating shaft 125 to drive the rotating shaft 125 to rotate. Specifically, the rotating shaft 125 is arranged along the third direction, and the two ends of the rotating shaft 125 are respectively rotatably connected to the first connecting plate 122. Exemplarily, the first driving mechanism 124 is detachably connected to the base 11 , and the mounting plate is an integrated structure to improve its mechanical strength.

[0047] Optionally, in this embodiment, the winding drums 126, first pulleys 127, and ropes 100 are provided in a one-to-one correspondence, and each winding drum 126 has a rope 100 wound therein. The ropes 100 are guided by the first pulleys 127 and then wound around the top support 14, thereby achieving one-to-one winding and release of the ropes 100. Under the action of the first pulleys 127, each rope 100 can be effectively guided to avoid entanglement. Specifically, a plurality of winding drums 126 are each sleeved on the rotating shaft 125, and a plurality of first pulleys 127 are rotatably provided outside the connecting shaft. The two ends of the connecting shaft are respectively connected to the mounting plate and are located below the support plate 123.

[0048] Furthermore, a limiting roller 128 is installed in the mounting base and is higher than the connecting shaft in the first direction. The connecting shaft is higher than the rotating shaft 125 in the first direction. Specifically, the limiting roller 128 is located above the first pulley 127, with a gap between them. The rope 100 is located between the limiting roller 128 and the first pulley 127. That is, after being guided by the first pulley 127, the rope 100 is limited by the limiting roller 128 before being connected to the top support 14. Exemplarily, the limiting roller 128 is located above all first pulleys 127. As a result, all ropes 100 can be limited by the limiting roller 128, preventing them from falling off the first pulleys 127.

[0049] For example, in this embodiment, the support plate 123 is located on the side of the limiting roller 128 facing the diagonal brace 13, and the rope 100, after being limited by the limiting roller 128, is passed through the space between the support plate 123 and the top surface of the base 11. As a result, the support plate 123 does not interfere with the movement of the rope 100, and the overall stability of the mounting base is ensured. Thus, with the multiple winding drums 126 rotating synchronously to retract and release the ropes 100 in parallel, the lifting assembly 20 can be raised and lowered synchronously at multiple lifting points, preventing the cargo from tilting. The support provided by the rotating shaft 125 effectively reduces wear on the transmission system.

[0050] Optionally, the diagonal brace 13 is arranged obliquely on the base 11, and the diagonal brace 13 gradually moves away from the base 11 in a direction away from the winding assembly 12 and extends out of the base 11 to ensure that the lifting height is suitable for the production, manufacturing and maintenance of the ship. For example, a plurality of diagonal braces 13 are arranged linearly along the third direction on the base 11, and each diagonal brace 13 is provided with a second connecting plate 131 in the direction facing the winding assembly 12. Specifically, a plurality of reinforcing diagonal braces 132 are arranged linearly along the third direction between the support plate 123 and the second connecting plate 131, and the reinforcing diagonal braces 132 are provided in a one-to-one correspondence with the diagonal braces 13, so that a stable triangular structure is formed by the diagonal braces 13, the reinforcing diagonal braces 132, the mounting seat and the base 11 to prevent the diagonal braces 13 from breaking.

[0051] Correspondingly, a reinforcing vertical brace 133 is arranged along the first direction between the diagonal brace 13 and the top surface of the base 11 to stably connect the diagonal brace 13 and the base 11, and a plurality of reinforcing vertical braces 133 are arranged linearly along the third direction on the base 11. The reinforcing vertical braces 133 are arranged one-to-one in correspondence with the diagonal brace 13, so that a stable triangular structure is formed by the diagonal brace 13, the reinforcing vertical brace 133 and the base 11, thereby preventing the diagonal brace 13 from rotating and breaking under the traction of the ship when hooking and lifting the ship. Therefore, the stable triangular structure formed by the diagonal brace 13, the reinforced diagonal brace 132 and the base 11, and the diagonal brace 13, the reinforced vertical brace 133 and the base 11 can improve the stability of the diagonal brace 13, and the diagonal brace 13, the reinforced diagonal brace 132 and the reinforced vertical brace 133 are all arranged linearly one to one, so that the lifting load can be evenly distributed, and under the action of the reinforced vertical brace 133, it can be evenly dispersed and transmitted to the base 11, and can effectively increase the rigidity of the connection point between the diagonal brace 13 and the base 11, improve the overall bending resistance of the device, and reduce the risk of deformation of the base 11 due to load concentration during lifting operations.

[0052] Optionally, the top support 14 is provided with a first bracket 141, a second bracket 142, a connecting bracket 143, a second pulley 144, and a third pulley 145. Optionally, the first bracket 141, the second bracket 142, and the connecting bracket 143 form an L-shaped structure, with the first bracket 141 extending upward in a first direction, and the second bracket 142 and the connecting bracket 143 both extending outward in a second direction away from the diagonal brace 13. Specifically, the connecting bracket 143 is connected to the top of the diagonal brace 13, and the first bracket 141 is arranged perpendicular to the connecting bracket 143. A plurality of second pulleys 144 are rotatably provided on the first bracket 141. Correspondingly, the second bracket 142 is connected to the end of the connecting bracket 143 facing away from the first bracket 141, and a plurality of third pulleys 145 are rotatably provided on the second bracket 142. Exemplarily, the first bracket 141, the second bracket 142, and the connecting bracket 143 are provided as an integrated structure to improve the overall mechanical strength.

[0053] Furthermore, in this embodiment, a plurality of second pulleys 144 are linearly arranged along the third direction on the first bracket 141, and a plurality of third pulleys 145 are linearly arranged along the third direction on the second bracket 142. The second pulleys 144 and the third pulleys 145 are arranged in a one-to-one correspondence with the ropes 100. Thus, the ropes 100 are sequentially guided through the second pulleys 144 and the corresponding third pulleys 145 and then connected to the hoisting assembly 20, thereby achieving a stable connection of the hoisting assembly 20. For example, in this embodiment, the winding drum 126, the first pulley 127, the second pulley 144, and the third pulley 145 are arranged in a one-to-one correspondence with the ropes 100, thereby forming multiple guide lines for the hoisting assembly 20, achieving multi-point connection, thereby ensuring the stability of the ship hoisting and preventing the ropes 100 from breaking during the hoisting process.

[0054] like Figure 5 As shown, in this embodiment, the lifting assembly 20 includes a hanging plate 21 and a hook 22, and a plurality of hooks 22 are provided. Specifically, a plurality of hooks 22 are arranged linearly on the hanging plate 21, and a plurality of ropes 10 are arranged linearly and connected to the hanging plate 21. The ropes 100 and the hooks 22 are respectively located on either side of the hanging plate 21. Thus, by winding the ropes 100, the hanging plate 21 can be driven to move up and down in a first direction. In turn, the hooks 22 under the hanging plate 21 can be used to drive the ship to move up and down synchronously with it in the first direction, thereby achieving the ship lifting operation. For example, the number of hooks 22 can be set as needed. In this embodiment, the number of hooks 22 is set to 6 and the number of ropes 100 is set to 5. Thus, the hooks 22 can be used to hook the ship at multiple points, thereby improving stability during the lifting process.

[0055] Combine Figure 6 and Figure 8 As shown, in this embodiment, the auxiliary assembly 30 includes a second drive mechanism 31, a movable base 32, and auxiliary rollers 33. The movable base 32 is provided with a support frame 321 and a slide 322. Optionally, the second drive mechanism 31 is detachably mounted in the receiving slot 101, and the output end of the second drive mechanism 31 is connected to the movable base 32. Specifically, the movable base 32 is slidably mounted on the extension plate 111 of the support platform 10 along the second direction, and the second drive mechanism 31 is used to drive the movable base 32. This allows the spacing between the two sets of auxiliary assemblies 30 to be adjusted to accommodate vessels of different sizes. Furthermore, a slope is provided on the side of the movable base 32 facing away from the support platform 10, and a plurality of auxiliary rollers 33 are rotatably mounted on the slope to provide oblique auxiliary support for the vessel. For example, the slope gradually moves away from the support platform 10 from its top to its bottom along the first direction. As a result, the plurality of auxiliary rollers 33 gradually move away from the base 11 and closer to the vessel from top to bottom along the first direction to provide auxiliary support.

[0056] Specifically, a plurality of support frames 321 are protruding from both sides of the movable seat 32 along the third direction, and each two symmetrically arranged support frames 321 form a group. An auxiliary roller 33 is rotatably provided on each group of support frames 321 to ensure the stable installation of the auxiliary roller 33 on the movable seat 32. For example, a slide 322 is protruding from the bottom of the movable seat 32, and the slide 322 is slidably provided in the chute 102, thereby enabling the sliding of the movable seat 32 on the extension plate 111, and then cooperating with the auxiliary roller 33 to provide lateral dynamic auxiliary support for the ship. Specifically, in this embodiment, the slide 322 is configured as a T-shaped plate, and the T-shaped plate is configured to correspond to the T-slot of the chute 102, so that the slide 322 can be engaged with the chute 102 to ensure a sliding connection while enabling it to slide stably along the second direction without separating from the extension plate 111. Exemplarily, the two ends of the vertical portion of the slide plate 322 are respectively connected to the horizontal portion and the movable seat 32, and the horizontal portion is slidably disposed in the lower groove of the slide groove 102, and the vertical portion is slidably disposed in the upper groove of the slide groove 102, thereby allowing the slide plate 322 to be limitedly clamped in the slide groove 102, so that the movable seat 32 cannot be separated from the extension plate 111. Exemplarily, the slide groove 102 and the slide plate 322 can also be configured with one cross-section being concave and the other cross-section being convex, so as to cooperate with the connection to achieve limited sliding between the two. In other embodiments, these configurations can be made as needed.

[0057] Working process: The first drive mechanism 124 drives the rotating shaft 125 to rotate, driving the synchronous rotation of the winding drum 126 to achieve the retraction and release of the rope 100. The rope 100 is then guided by the first pulley 127, limited by the limiting roller 128, and guided by the second pulley 144 and the third pulley 145 to form a multi-path traction effect on the hanging plate 21, allowing the hanging plate 21 to move up and down in the first direction. With the multi-point hooking action of the hook 22 on the ship, the ship can be raised and lowered in the first direction. At the same time, when the ship is lifted, the second drive mechanism 31 can drive the movable seat 32 to slide in the second direction on the extension plate 111, allowing the auxiliary roller 33 to conform to the surface of ships of different sizes, providing dynamic support and improving the stability of the ship during the lifting process. Therefore, the adjustable position of the auxiliary component 30 can provide dynamic auxiliary support for ships or hull components of different sizes, effectively reducing the manual intervention adjustment time by 60%.

[0058] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all embodiments here.
