Description

Technical Field

[0001] The invention relates to the technical field of water conservancy engineering, in particular to a water seal turning method. Background Art

[0002] The ship lift's lockhead sealing frame docking water seal is a key component in the ship lift's safe operation, sealing and stopping the flow of water between the ship compartment and the surrounding waters. The water seal is constructed by vulcanizing rubber segments into a single piece. Its cross-section is curved into a C-shape, and its overall shape is U-shaped. It is installed within the docking seal frame of the upper and lower lockhead working doors. The water seal is activated by the expansion and retraction of the seal frame, achieving a watertight seal between the ship compartment and the lockhead.

[0003] Because the C-type water seal is an active seal during use, it is subject to frequent back-and-forth movements (an average of approximately 30 movements per day during the trial navigation period). Its U-shaped layout and curled-up C-shape installation subject the seal to complex forces throughout its movement and filling and draining processes, particularly at its two corners. The C-type water seal forms a surface-type waterstop by sealing the joint gap area across its entire internal water-bearing surface, creating a large waterstop area. If the water seal fails, significant water leakage will occur into the working door, which houses numerous electromechanical equipment, seriously impacting both equipment safety and navigation safety.

[0004] Therefore, the water seal needs to be replaced regularly during use. The new water seal arrives as a whole with a C-shaped cross-section. The installation sequence is to first unfold the water seal in the hall, fix it at multiple points, and then hoist it as a whole. However, the water seal is made of rubber, which is soft and has poor overall rigidity. It is easy to deform during hoisting and is difficult to fix, resulting in the overall installation process having many steps and a long construction period. Summary of the Invention

[0005] The purpose of the present invention is to overcome the shortcomings of the prior art and provide a water-sealed turning method.

[0006] The purpose of the present invention is achieved through the following technical solutions: A water seal turning method, comprising the following steps:

[0007] Bend the water seal as a whole into a U shape and place it on a plurality of first supporting mechanisms and a second supporting mechanism, wherein the first supporting mechanism supports the middle portion of the water seal, and the second supporting mechanism supports the bent sections at both ends of the water seal, and the bottom of the first supporting mechanism is provided with running wheels;

[0008] Insert and install the aluminum tube into the groove formed by the curling of the water seal;

[0009] Connecting the two ends of the hanger to the two ends of the water seal, wherein the hanger is connected to the middle position of the water seal through a plurality of connecting pieces;

[0010] Raise the hanger, the two ends of the water seal rise and separate from the second supporting mechanism, the middle position of the water seal is supported by the first supporting mechanism, and the first supporting mechanism slides with the middle position of the water seal until the bending sections at both ends of the water seal are in a vertical state.

[0011] In the present invention, the groove formed by the natural curling of the water seal is used, and an aluminum tube is embedded in the groove to enhance the rigidity of the water seal. The support of the first supporting mechanism further prevents the water seal from being dragged and deformed when the hanger is lifted.

[0012] In some embodiments, the second supporting mechanism includes a scissor lift mechanism and a curved supporting plate mounted on top of the scissor lift mechanism for supporting the water seal. The scissor lift mechanism adjusts the height of the second supporting mechanism so that the supporting surface of the second supporting mechanism is aligned with the height of the first supporting mechanism, ensuring that all sections of the water seal are coplanar when placed.

[0013] In some embodiments, the scissors-fork lifting mechanism includes a top plate, a bottom plate and a scissors-fork frame; one side of the top of the scissors-fork frame is hinged to the top plate, and the other side is slidingly connected to the top plate; one side of the bottom of the scissors-fork frame is hinged to the bottom plate, and the other side is slidingly connected to the bottom plate; a screw is rotatably connected to the bottom plate, and the direction of the screw is the sliding direction of the sliding side of the bottom of the scissors-fork frame, and the screw is threadedly connected to the sliding side of the bottom of the scissors-fork frame.

[0014] In some embodiments, the first supporting mechanism includes a base and a flip supporting member, the bottom of the base is provided with a plurality of running wheels, and the two sides of the base are provided with side panels, the flip supporting member is hinged to the side panels on both sides of the base via a hinge shaft, and the top of the flip supporting member is provided with a U-shaped supporting groove, and the water seal is placed in the supporting groove. By hingedly connecting the flip supporting member to the base, the flip supporting member can rotate relative to the base. During the lifting process of the hanger, the two ends of the water seal are lifted and gradually change from a horizontal state to a vertical state, while the middle position of the water seal rotates and is dragged horizontally toward the hanger. The first supporting mechanism can provide support for the water seal when the middle position of the water seal is dragged and rotated.

[0015] In some embodiments, the height of the middle portion of the side panel is higher than that of the ends thereof, and the tilt support member is hingedly connected to the highest point of the middle portion of the side panel via a hinge axis. The side panels are configured so that the heights of the sides are lower than the height of the middle portion to avoid interference with the side panels during rotation of the middle portion of the water seal.

[0016] In some embodiments, the diameter of the aluminum tube is equal to the width of the groove formed by the curling of the water seal. The aluminum tube can fully contact the water seal, provide sufficient support for the water seal, and prevent the water seal from deforming.

[0017] In some embodiments, the hanger includes a hanger body and two connecting frames, the ends of the two connecting frames being respectively connected to the ends of the hanger body, and the two connecting frames being respectively connected to the ends of the water seal by bolts. The connecting frames are connected to the water seal by bolts, thereby ensuring a stable connection to the water seal.

[0018] In some embodiments, the width of the connecting frame is equal to the width of the groove formed by curling the water seal, and the connecting frame is provided with openings corresponding to the mounting holes on the water seal.

[0019] In some embodiments, when bolting the water seal to the connecting frame, the following steps are included:

[0020] Place the connecting frame into the groove formed by the curling of the water seal so that the side of the water seal fits into the connecting frame;

[0021] The openings on the connecting frame are aligned with the mounting holes on the water seal, and bolts are used to connect the connecting frame and the water seal through the corresponding mounting holes and openings. By setting the width of the connecting frame to match the groove width of the water seal, deformation of the water seal is avoided when the water seal and the connecting frame are bolted together. At the same time, the use of multiple bolts prevents concentrated force on the water seal, further reducing deformation of the water seal.

[0022] In some embodiments, the connecting member includes a sling and a ring, one end of the sling is connected to the hanger, and the other end is connected to the ring, the middle position of the water seal is passed through the ring and is supported by the ring when the hanger is raised. The middle position of the water seal is supported by the connecting member to avoid the weight of the middle position of the water seal being completely borne by the bent positions at both ends of the water seal after the water seal is completely lifted, thereby further reducing the deformation of the water seal.

[0023] The present invention has the following advantages:

[0024] The present invention embeds an aluminum tube in the groove of the water seal to increase the rigidity of the water seal through the aluminum tube, thereby preventing the water seal from being deformed by force when the water seal is lifted; and provides a first supporting mechanism and a second supporting mechanism so that the water seal is located in the same horizontal plane as a whole before being lifted and turned over by the hanger, thereby preventing deformation; during the lifting and turning process, the first supporting mechanism slides as the middle position of the water seal is dragged, and provides support for the water seal while cooperating with the rotation of the middle position of the water seal, thereby further reducing the deformation of the water seal during the turning process.

[0032] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for the purpose of explaining the present invention and are not intended to limit the present invention. That is, the embodiments described herein are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and illustrated in the drawings herein can be arranged and designed in various different configurations.

[0033] The present invention will be further described below in conjunction with the accompanying drawings, but the protection scope of the present invention is not limited to the following description.

[0034] like Figures 1-6 As shown, a water seal turning method includes the following steps:

[0035] First, bend the water seal into a U shape and place it on a plurality of first supporting mechanisms 1 and second supporting mechanisms 2. The first supporting mechanism 1 supports the middle of the water seal, and the second supporting mechanism 2 supports the bent sections at both ends of the water seal. The bottom of the first supporting mechanism 1 is provided with running wheels 12.

[0036] Specifically, in this embodiment, the bent sections at both ends of the water seal are supported by three second supporting mechanisms 2 respectively, and the middle position of the water seal is supported by three first supporting mechanisms 1. The water seal is supported by multiple first supporting mechanisms 1 and second supporting mechanisms 2 to avoid concentrated force on the water seal, so that each section of the water seal is evenly stressed, and to avoid deformation of the water seal under the action of gravity.

[0037] Then, insert the aluminum tube 5 into the groove formed by the curling of the water seal;

[0038] Specifically, since the bent positions on both sides of the water seal are in a vertical state after being lifted by the hanger 3 during the turning process, they are not easily deformed, while the middle position of the water seal is still in a horizontal state after being lifted by the hanger 3 and is easily deformed, the aluminum tube 5 in this embodiment is embedded in the middle position of the water seal, and the aluminum tube 5 in this embodiment is arranged in sections and connected end to end. In some other embodiments, the aluminum tube 5 can also be an integral structure.

[0039] Then connect the two ends of the hanger 3 to the two ends of the water seal, and the hanger 3 is connected to the middle position of the water seal through several connecting pieces 4;

[0040] Specifically, in this embodiment, three connecting members 4 are provided, and the three connecting members 4 provide sufficient support for the water seal.

[0041] Finally, the hanger 3 is raised, the two ends of the water seal are raised and separated from the second supporting mechanism 2, and the middle position of the water seal is supported by the first supporting mechanism 1. The first supporting mechanism 1 slides with the middle position of the water seal until the bending sections at both ends of the water seal are in a vertical state.

[0042] Since the hanger 3 rises vertically, the middle position of the water seal will be dragged toward the hanger 3 during the process of the bent sections at both ends of the water seal being lifted to a vertical state. In order to cooperate with the movement of the middle position of the water seal, a first supporting mechanism 1 is provided, and walking wheels 12 are provided on the first supporting mechanism 1, so that the first supporting mechanism 1 can provide support for the water seal while following the middle position of the water seal being dragged, thereby avoiding deformation of the water seal during the dragging process.

[0043] Preferably, the second supporting mechanism 2 includes a scissor lift mechanism 21 and a supporting plate 22 provided on top of the scissor lift mechanism 21 for supporting the water seal. The supporting plate 22 is arc-shaped. The arc-shaped supporting plate 22 fits the water seal during the supporting process, so that the water seal is evenly stressed and deformation of the water seal is avoided.

[0044] Preferably, the scissors fork lifting mechanism 21 includes a top plate 211, a bottom plate 212 and a scissors fork frame 213; one side of the top of the scissors fork frame 213 is hinged to the top plate 211, and the other side is slidably connected to the top plate 211; one side of the bottom of the scissors fork frame 213 is hinged to the bottom plate 212, and the other side is slidably connected to the bottom plate 212; a screw 23 is rotatably connected to the bottom plate 212, and the direction of the screw 23 is the sliding direction of the sliding side of the bottom of the scissors fork frame 213, and the screw 23 is threadedly connected to the sliding side of the bottom of the scissors fork frame 213.

[0045] The scissor frame includes two sets of scissor arms, each set of scissor arms includes two hinged scissor arms, and the two scissor arms are hinged into an X shape. The two sets of scissor arms are arranged side by side. Connecting rods are provided at the corresponding end positions of the two sets of scissor arms to connect the two sets of scissor arms to form a scissor frame 213. Slide grooves are provided on both sides of the top plate 211 and the bottom plate 212. The connecting rod on one side of the bottom of the scissor frame 213 is hinged to the slide grooves on both sides of the bottom plate 212, and the two ends of the connecting rod on the other side of the bottom of the scissor frame 213 are slidably connected to the slide grooves on both sides of the bottom plate 212; the connecting rod on one side of the top of the scissor frame 213 is hinged to the slide grooves on both sides of the top plate 211, and the two ends of the connecting rod on the other side of the top of the scissor frame 213 are slidably connected to the slide grooves on both sides of the top plate 211. One end of the screw is rotatably connected to one end of the bottom plate 212, and the other end is threadedly connected to the connecting rod on the side of the bottom of the scissor frame 213 that is slidably connected to the bottom of the bottom plate 212.

[0046] By rotating the screw 23 set on the bottom plate 212, the screw 23 can be rotated to make the bottom side of the scissor frame 213 slide, thereby driving the scissor frame 213 to move up and down, and finally driving the top plate 211 to move up and down. Through the lifting second supporting mechanism 2, the height of the supporting plate 22 can be adjusted so that the various sections of the water seal are located in the same plane, reducing deformation.

[0047] Preferably, the first supporting mechanism 1 includes a base 11 and a flip supporting member 13, a plurality of walking wheels 12 are provided at the bottom of the base 11, side panels 111 are provided on both sides of the base 11, the flip supporting member 13 is hinged to the side panels 111 on both sides of the base 11 through a hinge shaft 14, and a U-shaped supporting groove 131 is provided at the top of the flip supporting member 13, and the water seal is placed in the supporting groove 131.

[0048] In this embodiment, the walking wheel 12 is a Fomar wheel; a supporting groove 131 is provided on the top of the flip support member 13, and the bottom is hinged to the side plate 111 of the base 11, and a bearing is provided on the hinge shaft 14. The flip support member 13 is fixedly connected to the bearing. The bearing is provided to make the rotation of the flip support member 13 smoother.

[0049] Since the bent sections at both ends of the water seal are lifted to a vertical state during the process of turning over and lifting the water seal, the middle position of the water seal will also rotate accordingly. Therefore, the flip support member 13 is set to a rotatable structure so that the flip support member 13 rotates as the water seal rotates, providing support for the water seal during the rotation process.

[0050] Preferably, the height of the middle position of the side panel 111 is higher than the heights of the two end positions thereof, and the flip support member 13 is hinged to the highest point of the middle position of the side panel 111 through the hinge shaft 14 .

[0051] The height of the middle position of the side panel 111 is higher than the height of its two ends, so that the flip support member 13 is hinged to the highest point of the side panel 111. During the rotation of the flip support member 13, since the supporting groove 131 is located at the top of the flip support member 13, the height of the flip supporting groove 131 will be reduced. The height of the two ends of the side panel 111 is set to be lower than the height of the middle position to avoid interference between the water seal and the side panel 111.

[0052] Preferably, the diameter of the aluminum tube 5 is equal to the width of the groove formed by the curling of the water seal, so that the aluminum tube 5 fits tightly with the water seal without any gap, providing sufficient support for the water seal, further improving the rigidity of the water seal and preventing the water seal from deforming.

[0053] Preferably, the hanger 3 includes a hanger body 31 and two connecting brackets 32. The ends of the two connecting brackets 32 are respectively connected to the ends of the hanger body 31, and the two connecting brackets 32 are respectively connected to the ends of the water seal by bolts. The bolt connection between the hanger 3 and the water seal fully utilizes the existing mounting holes on the water seal and reduces deformation of the water seal.

[0054] Preferably, the width of the connecting frame 32 is equal to the width of the groove formed by curling the water seal, and the connecting frame 32 is provided with openings corresponding to the mounting holes on the water seal.

[0055] Preferably, when the water seal and the connecting frame 32 are connected by bolts, the following steps are included:

[0056] Place the connecting frame 32 into the groove formed by the curling of the water seal so that the side of the water seal fits in with the connecting frame 32;

[0057] The openings on the connecting frame 32 are aligned with the mounting holes on the water seal, and bolts are used to connect the connecting frame 32 and the water seal through the corresponding mounting holes and openings. By setting the width of the connecting frame 32 to the width of the water seal groove, the water seal maintains its shape after being bolted to the connecting frame 32 and does not deform. The use of multiple bolts to connect the water seal prevents concentrated force on the water seal during lifting, further preventing deformation of the water seal.

[0058] Preferably, the connecting member 4 includes a sling 41 and a lifting ring 42. One end of the sling 41 is connected to the hanger 3, and the other end is connected to the lifting ring 42. The middle part of the water seal is inserted into the lifting ring 42 and is supported by the lifting ring 42 when the hanger 3 is raised. The lifting ring 42 supports the middle part of the water seal to prevent deformation of the water seal during the process of turning over and lifting.

[0059] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Any person skilled in the art can, without departing from the scope of the technical solution of the present invention, make many possible changes and modifications to the technical solution of the present invention using the above technical content, or modify it into an equivalent embodiment with equivalent changes.
