Description

Technical Field

[0001] This invention relates to the field of ship lift maintenance technology, and in particular to a method for maintaining the support slider of the docking sealing frame of a ship lift. Background Technology

[0002] This invention is a divisional application of the original application number 202210465811.3, entitled "A Maintenance Device and Method for a Support Slider of a Ship Lift Docking Sealing Frame".

[0003] As a navigation structure, the ship lift, compared to the lock, has the advantages of adapting to higher water heads, shorter throughput time, and lower energy consumption. The docking sealing frame, as a crucial operating component of the ship lift, is used to ensure a watertight connection between the ship lift's cargo box and the upper and lower lock gates. During normal operation, the support slider of the docking sealing frame slides back and forth along the support surface of the ship lift's cargo box. The weight of the docking sealing frame is borne by the support slider. When wear occurs on the slider, causing the sliding clearance to exceed the normal range, the docking sealing frame is prone to jamming during its extension and retraction. In severe cases, this can lead to incomplete sealing and water leakage, posing a significant safety hazard. The support slider is fixed to the docking sealing frame with bolts. During normal operation, there is no space to disassemble the support slider. For maintenance and replacement, the sealing frame must be pushed out, and the support slider must be completely detached from the support surface of the ship lift's cargo box. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a method for overhauling the support slider of the docking sealing frame of a ship lift. This overhaul device enables rapid overhaul and replacement of the support slider of the docking sealing frame, and the overhaul method is adaptable to the on-site overhaul operation environment, ensuring construction safety and improving overhaul efficiency.

[0005] To achieve the above-mentioned technical features, the present invention aims to provide a method for overhauling the support slider of a docking sealing frame of a ship lift, comprising a bottom support wheel frame, a bottom bracket, a side support wheel frame, and a side bracket; multiple sets of the bottom support wheel frames are arranged at the bottom of the docking sealing frame and are slidably supported on the top of the bottom bracket; multiple sets of the bottom bracket are installed on the bottom longitudinal beam of the ship lift's cabin head; multiple sets of the side support wheel frames are symmetrically arranged on both sides of the docking sealing frame and are slidably engaged with the side bracket; multiple sets of the side brackets are installed on the two end faces of the ship lift's cabin head. The mating sealing frame is connected to multiple sets of drive components for reciprocating movement along the base bracket and side bracket.

[0006] Both the bottom support wheel frame and the side support wheel frame include a wheel frame, multiple pins, and multiple support wheels; the front and rear ends of the wheel frame are mounted on the mating sealing frame by screws, and the multiple support wheels are mounted on the wheel frame by pins, with wheel grooves machined on the support wheels.

[0007] The bottom bracket and side brackets both include a track support, a track, and a limiting plate. The bottom bracket also includes a box beam, a connecting plate, and a clamping block. The track in the bottom bracket is installed on the track support, and the track mates with the wheel grooves on the support wheels. One end of the track support is in contact with the bottom end face of the ship lift's cabin head, and the other end is limited by the limiting plate. The box beam is installed between the bottom longitudinal beams of the ship lift's cabin head and connected by bolts. The box beam is fixed to the track support by the connecting plate. Two clamping blocks are respectively arranged at both ends of the box beam. The clamping blocks are used to vertically clamp and limit the box beam to the longitudinal beams by multiple bolts. The side bracket also includes a base located on the end face of the track support.

[0008] Multiple sets of support sliders are provided between the ship lift cabin head and the docking sealing frame. The support sliders include inner support sliders and outer support sliders, which are respectively arranged inside and outside the docking sealing frame and supported by the support surface of the ship lift cabin head.

[0009] The drive assembly consists of five groups, each group consisting of two sets, a and b, with the same structure. The drive assembly includes a drive cylinder, a disc spring assembly, a support rod, a screw, a nut, a bushing, and a screw. The drive cylinder is hinged to the head of the ship lift cabin via a cylinder hinge seat. The piston rod end of the drive cylinder is connected to a support rod, and a disc spring assembly is fitted on the outside of the support rod. The other end of the support rod is fixed to a bushing by a screw and a nut. The bushing is fixedly connected to the docking sealing frame by a screw.

[0010] One end of the support rod in the drive assembly can be threadedly connected to the connecting assembly. The connecting assembly includes multiple connecting rods, a special-shaped flange, an end cap, and n screws. One end of the connecting rod is a stepped threaded shaft, and the other end is machined with a central hole and n evenly distributed threaded holes. The special-shaped flange is machined with a central stepped hole and four sets of grooves and through holes evenly distributed on its outer contour. The end cap has a circular boss, and three sets of U-shaped grooves and n countersunk holes are evenly distributed on its end face. The center distance of the countersunk holes is the same as the center distance of the threaded holes on the end face of the connecting rod.

[0011] During installation, the stepped hole of the shaped flange is assembled with one end of the support rod. The circular boss on the end cover passes through the stepped hole of the shaped flange and is connected to the support rod by screw two. Screw two is tightened in two steps: First, tighten screw two until the gap between the shaped flange and the end cover is between 0.5 and 1 mm, ensuring that the shaped flange can rotate freely along the axis. Use a hook wrench to hold the U-shaped groove on the end cover and rotate the connecting rod to connect the connecting rod with the support rod. Second, manually adjust the position of the shaped flange so that the evenly distributed through holes of the shaped flange are aligned with the diameter of the holes on the bushing, and then tighten screw two. The bushing and the mating sealing frame are connected by screw one.

[0012] The value of n is between 6 and 8.

[0013] The method for overhauling the support slider of the docking sealing frame of the ship lift using an inspection device includes the following steps: Step 1, C-type water stop removal: Multiple sets of drive components operate simultaneously, and the sealing frame is pushed out by displacement h through the compression force transmission of the disc spring group, ensuring that the C-type water stop is in a natural deformation state, and the C-type water stop and the upper and lower pressure plates are removed. Step 2, Installation of maintenance equipment: First, install the bottom bracket and side bracket at the head of the ship lift cabin. Then, install and adjust the bottom support wheel frame, bottom bracket, and side support wheel frame on the outside of the docking sealing frame to ensure that the support wheels are assembled with the rails. Step 3, Installation of connecting components: The five sets of drive components operate simultaneously. When the drive cylinder extends to its maximum stroke for the first time, the sealing frame is pushed out synchronously. First, remove the screw, nut, and four screws from drive component a. Install the connecting components, ensuring that the first connecting rod and the support rod are in contact. Retract the drive cylinder in drive component a to its initial position. Secure the flange and bushing with screw one. Next, alternately install the connecting components on drive component b, using the same method as drive component a. Step 4, Secondary Extension of the Docking Sealing Frame: All five drive components operate simultaneously. When the drive cylinder extends to its maximum stroke for the second time, the docking sealing frame is simultaneously extended. At this point, the support slider near the front end of the docking sealing frame has disengaged from the support surface of the ship lift's cabin head. The weight of the docking sealing frame is supported by the support wheels and the track. First, remove the shaped flange, end cap, screw two, and four screws one installed on drive component a, retaining the first connecting rod. Then, install the second connecting rod and reinstall the shaped flange, end cap, and screw two. Retract the drive cylinder in drive component a to its initial position. The shaped flange and bushing are fixed together by screw one. Next, alternately install the connecting components on drive component b, using the same installation method as drive component a. Step 5, the docking sealing frame is pushed out into place: the five sets of drive components act simultaneously, and the docking sealing frame is pushed out synchronously when the drive cylinder extends to its maximum stroke for the third time. At this time, the support slider has completely disengaged from the support surface of the ship lift's cabin head, and the weight of the docking sealing frame is supported by the support wheel and the track. Step 6, Disassembly and assembly of support slider: Remove the support slider, select a reference and mark it, and when reassembling and adjusting the new support slider, it should meet the corresponding technical requirements; Step 7, retraction of the sealing frame: All five drive components operate simultaneously. When the drive cylinder retracts to its first position, the sealing frame retracts synchronously. First, remove screw one between the shaped flange and the bushing in drive component a, then extend the drive cylinder to its maximum stroke. Sequentially remove the second connecting rod, screw two, end cap, and shaped flange. Reinstall the shaped flange, end cap, screw two, and screw one between the shaped flange and the bushing. Extend the drive cylinder to its maximum stroke and install the connecting screw between the shaped flange and the bushing. Next, alternately remove the connecting components on drive component b, using the same removal method as drive component a. Step 8, Secondary Retraction of the Sealing Frame: All five drive components operate simultaneously. When the drive cylinder retracts to its second position, the sealing frame retracts synchronously. First, remove screw one between the flange and bushing in drive component a, then extend the drive cylinder to its maximum stroke. Sequentially remove the first connecting rod, screw two, end cap, and flange. Reinstall screw one, threaded rod, and nut. Next, alternately remove the connecting components on drive component b, using the same removal method as drive component a. Step 9, Dismantle the maintenance device: Measure and inspect whether the installation of the support slider meets the technical requirements in Step 6. If it meets the requirements, the bottom bracket, bottom support wheel frame, side bracket and side support wheel frame can be disassembled and assembled; if it does not meet the requirements, repeat Steps 3 to 8. Step 10, C-type waterstop reinstallation: The mating sealing frame is retracted to the position in Step 1, and the C-type waterstop and upper and lower pressure plates are installed.

[0014] The corresponding technical requirements in step six are as follows: First, the bottom outer support slider of the docking sealing frame must be tightly attached to the support surface of the ship lift's cabin head. The number of outer support sliders that are not attached must not exceed 3, and the gap must not be greater than 1mm. Second, the bottom inner support slider and the support surface have a sliding gap of 4~9mm, and the relative difference is no more than 1mm; Third, the outer support sliders on both sides of the sealing frame should be in contact with the support surface. The number of unin contacted outer support sliders should not exceed 3, and the gap should not be greater than 1mm. Fourth, the gap between the inner support sliders on both sides and the support surface is ≥2mm, and the relative difference in gaps on the same side is ≤1mm.

[0015] The present invention has the following beneficial effects: 1. This invention proposes a method for overhauling the support slider of the docking sealing frame of a ship lift. The device, by installing and arranging multiple sets of brackets and support wheel frames, can provide support and guidance during the pushing out and retraction of the docking sealing frame, thereby preventing the docking sealing frame from getting stuck or tilting.

[0016] 2. The structure and installation layout of the multiple brackets and support wheel frames are matched and adapted to the structural characteristics of the ship lift's cabin head. The device is easy to disassemble and assemble, meets the requirements for maintenance and replacement of the support slider, ensures construction safety, and improves maintenance efficiency.

[0017] 3. The connecting assembly is used to connect the drive assembly and the mating sealing frame. By increasing or decreasing the number of support rods installed, the mating sealing frame can be pushed out to the maintenance position.

[0018] 4. During the maintenance process, by alternately installing connecting components on drive assemblies a and b, the drive assembly is always fixedly connected to the docking sealing frame, preventing deviation or tilting of the docking sealing frame due to unrestrained fixation along the ejection direction, thus ensuring operational safety.

[0019] 5. In the maintenance method, it is clearly stated that the technical requirements described in step six should be met when reinstalling and adjusting the new support slider to ensure the quality of maintenance. Attached Figure Description

Detailed Implementation

[0042] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0043] Example 1: like Figure 1-6As shown, a method for overhauling the support slider of a docking sealing frame of a ship lift includes a bottom support wheel frame 1.1, a bottom bracket 2.1, a side support wheel frame 1.2, and a side bracket 2.2. Multiple sets of the bottom support wheel frames 1.1 are arranged at the bottom of the docking sealing frame 4 and are slidably supported on the top of the bottom bracket 2.1. Multiple sets of the bottom brackets 2.1 are installed on the bottom longitudinal beam of the ship lift's cabin head 3. Multiple sets of the side support wheel frames 1.2 are symmetrically arranged on both sides of the docking sealing frame 4 and are slidably engaged with the side brackets 2.2. Multiple sets of the side brackets 2.2 are installed on the two end faces of the ship lift's cabin head 3. The docking sealing frame 4 is connected to multiple sets of drive components 5 for reciprocating movement along the bottom bracket 2.1 and the side brackets 2.2. This overhaul device with the above structure provides support and guidance during the pushing and pulling of the docking sealing frame, preventing jamming or tilting of the docking sealing frame.

[0044] like Figure 7-8 As shown, both the bottom support wheel frame 1.1 and the side support wheel frame 1.2 include a wheel frame 101, multiple pins 102, and multiple support wheels 103. The front and rear ends of the wheel frame 101 are mounted on the mating sealing frame 4 with screws. The multiple support wheels 103 are mounted on the wheel frame 101 with pins 102, and each support wheel 103 has a groove. By using the bottom support wheel frame 1.1, the entire mating sealing frame 4 can be supported, thus facilitating its rolling support. The side support wheel frame 1.2 provides lateral restraint for the mating sealing frame 4, preventing jamming and tilting during movement.

[0045] Furthermore, both the bottom bracket 2.1 and the side bracket 2.2 include a track support 201, a track 204, and a limiting plate 205. The bottom bracket 2.1 also includes a box beam 202, a connecting plate 203, and a clamping block 206. In the bottom bracket 2.1, the track 204 is installed on the track support 201, and the track 204 mates with the wheel groove on the support wheel 103. One end of the track support 201 is in contact with the bottom end face of the ship lift's cabin head 3, and the other end is connected by the limiting plate 205. 5. Limiting is performed. The box girder 202 is installed between the bottom longitudinal beams of the ship lift's cabin head 3 and connected by bolts. The box girder 202 is fixed to the track support 201 by a connecting plate 203. The two clamping blocks 206 are respectively arranged at both ends of the box girder 202. The clamping blocks 206 are used to vertically clamp and limit the box girder 202 to the longitudinal beams by multiple bolts. The side bracket 2.2 also includes a base 207, which is located on the end face of the track support 201. Through the bottom bracket 2.1 and the side bracket 2.2, rolling support can be achieved for the bottom support wheel frame 1.1 and the side support wheel frame 1.2, thereby achieving support for the docking sealing frame 4 they support.

[0046] like Figure 6 and 12As shown in -14, the docking sealing frame 4 extends and retracts back and forth through five sets of drive components 5, and the multiple sets of support sliders 7 include inner support sliders 7.1 and outer support sliders 7.2. The inner support sliders 7.1 and outer support sliders 7.2 are respectively arranged inside and outside the docking sealing frame 4 and are supported by the support surface of the ship lift cabin head 3.

[0047] like Figure 9-11 As shown, the drive assembly 5 consists of five sets, each set comprising two identical structures, a and b. Each drive assembly 5 includes a drive cylinder 501, a disc spring assembly 502, a support rod 503, a screw 504, a nut 505, a bushing 506, and a screw 507. The drive cylinder 501 is hinged to the head of the ship lift 3 via a cylinder hinge seat. The piston rod end of the drive cylinder 501 is connected to the support rod 503, and the disc spring assembly 502 is fitted onto the outside of the support rod 503. The other end of the support rod 503 is fixed to the bushing 506 via the screw 504 and nut 505. The bushing 506 is fixedly connected to the docking sealing frame 4 via screw 507. By alternately installing the connecting components on the a and b sets of drive assemblies, the drive assembly is always fixedly connected to the docking sealing frame, preventing deviation or tilting of the docking sealing frame due to lack of constraint along the pushing direction, thus ensuring operational safety. The aforementioned drive assembly 5 enables the pushing of the docking sealing frame 4. During operation, the drive cylinder 501 drives the disc spring assembly 502 and the support rod 503, and the support rod 503 drives the docking sealing frame 4 connected to it.

[0048] Furthermore, one end of the support rod 503 in the drive assembly 5 can be threadedly connected to the connecting assembly 6. The connecting assembly 6 includes multiple connecting rods 601, a special-shaped flange 602, an end cap 603, and n screws 604. One end of the connecting rod 601 is a stepped threaded shaft, and the other end is machined with a central hole and n evenly distributed threaded holes. The special-shaped flange 602 is machined with a central stepped hole and four sets of grooves and through holes evenly distributed on its outer contour. The end cap 603 has a circular boss, and three sets of U-shaped grooves and n countersunk holes are evenly distributed on its end face. The center distance between the countersunk holes is the same as the center distance between the threaded holes on the end face of the connecting rod 601. Through the above-mentioned connecting assembly 6, the connection between the support rod 503 and the mating sealing frame 4 can be realized, thereby achieving the lengthening of the support rod 503.

[0049] Furthermore, during the installation of the connecting assembly 6, the stepped hole of the shaped flange 602 is assembled with one end of the support rod 503. The circular boss on the end cover 603 passes through the stepped hole of the shaped flange 602 and is connected to the support rod 503 by screw two 604. Screw two 604 is tightened in two steps: First, screw two 604 is tightened until the gap between the shaped flange 602 and the end cover 603 is between 0.5 and 1 mm, ensuring that the shaped flange 602 can rotate freely along the axis. A hook wrench is used to hold the U-shaped groove on the end cover 603 and rotate the connecting rod 601 to connect the connecting rod 601 to the support rod 503. Second, the position of the shaped flange 602 is manually adjusted so that the evenly distributed through holes of the shaped flange 602 are aligned with the diameter of the holes on the bushing 506, and then screw two 604 is tightened. The bushing 506 is connected to the mating sealing frame 4 by screw one 507. Through the above connection and assembly process, the lengthening operation of the support rod 503 is thus realized.

[0050] Furthermore, the value of n is 6-8.

[0051] Example 2: The maintenance method for the supporting slider of the docking sealing frame includes the following steps: like Figure 15-17 As shown, in step one, the C-type water stop is removed: the five sets of drive components 5 operate simultaneously, and the pressure transmitted through the disc spring assembly 502 causes the mating sealing frame 4 to be pushed out by a displacement h. The state of the C-type water stop 8 is as follows. Figure 17 Ensure that the C-type waterstop 8 is in a state of natural deformation, such as Figure 17 Remove the C-type waterstop 8 and the upper and lower pressure plates; like Figure 4 and 6 As shown, in step two, the maintenance device is installed: First, the bottom bracket 2.1 and the side bracket 2.2 are installed at the head 3 of the ship lift. Then, the bottom support wheel frame 1.1, the bottom bracket 2.1, and the side support wheel frame 1.2 are installed and adjusted on the outside of the docking sealing frame 4 to ensure that the support wheel 103 is assembled with the track 204. like Figure 18 As shown in (a)(b)(c)(d), step three is the installation of the connecting components. The five sets of drive components 5 operate simultaneously. When the drive cylinder 501 extends to its maximum stroke for the first time, the mating sealing frame 4 is pushed out synchronously. First, remove the screw 504, nut 505, and four screws 507 from drive component a. Install the connecting components 6, ensuring that the first connecting rod 601 is flush with the connecting end face of the support rod 503. Retract the drive cylinder 501 from drive component a to its initial position. The shaped flange 602 and the bushing 506 are fixed together by screws 507. Next, alternately install the connecting components 6 on drive component b, using the same installation method as drive component a. like Figure 19As shown in (a)(b)(c), in step four, the docking sealing frame is extended for the second time: the five sets of drive components 5 operate simultaneously, and the docking sealing frame 4 is extended to its maximum stroke for the second time. At this time, the support slider 7 near the front end of the docking sealing frame 4 has disengaged from the support surface of the ship lift's cabin head 3, and part of the self-weight of the docking sealing frame 4 is supported by the support wheel 103 and the track 204. First, the special flange 602, end cap 603, screw 604 and four screws 507 installed on drive component a are removed respectively, while the first connecting rod 601 is retained. The second connecting rod 601 is added as a whole, and the special flange 602, end cap 603 and screw 604 are reinstalled. The drive cylinder 501 in drive component a is retracted to the initial position, and the special flange 602 and bushing 506 are fixed by screw 507. Next, the connecting components 6 are alternately installed on drive component b, and the installation method is the same as that of drive component a. like Figure 20 As shown, in step five, the docking sealing frame is pushed out into place: the five sets of drive components 5 act simultaneously, and when the drive cylinder 501 extends to its maximum stroke for the third time, the docking sealing frame 4 is pushed out synchronously. At this time, the support slider 7 has completely disengaged from the support surface of the ship lift cabin head 3, and the weight of the docking sealing frame 4 is supported by the support wheel 103 and the track 204.

[0052] Step Six, Disassembly and Assembly of Support Sliders: Remove support slide 7, select a reference and mark it. When reassembling and adjusting the new support slide 7, the following technical requirements should be met: 1. The bottom outer support slide 7.2 of the docking sealing frame 4 should be tightly attached to the support surface of the ship lift's cabin head 3. The number of outer support slides 7.2 that are not attached should not exceed 3, and the gap should not be greater than 1mm; 2. The bottom inner support slide 7.1 should have a sliding gap of 4~9mm with the support surface, and the relative difference should not be greater than 1mm; 3. The outer support slides 7.2 on both sides of the docking sealing frame 4 should be attached to the support surface. The number of outer support slides 7.2 that are not attached should not exceed 3, and the gap should not be greater than 1mm; 4. The gap between the inner support slides 7.1 on both sides and the support surface should be ≥2mm, and the relative difference of the gap on the same side should be ≤1mm; Step 7, retraction of the sealing frame: The five sets of drive components 5 operate simultaneously. When the drive cylinder 501 retracts to its position for the first time, the sealing frame 4 retracts synchronously. First, remove the screw 507 between the shaped flange 602 and the bushing 506 in the drive component 5, then extend the drive cylinder 501 to its maximum stroke. Sequentially remove the second connecting rod 601, screw 604, end cap 603, and shaped flange 602. Reinstall the shaped flange 602, end cap 603, screw 604, and screw 507 between the shaped flange 602 and the bushing 506. Extend the drive cylinder 501 to its maximum stroke and install the connecting screws between the special flange 602 and the bushing 506; then, alternately remove the connecting component 6 on the drive assembly 5 of set b, and the removal method is the same as that of the drive assembly 5 of set a above. Step 8, Secondary Retraction of the Sealing Frame: The five sets of drive components 5 operate simultaneously. When the drive cylinder 501 retracts to its second position, the sealing frame 4 retracts synchronously. First, remove the screw 507 between the flange 506 and the bushing 506 in drive component a, then extend the drive cylinder 501 to its maximum stroke. Sequentially remove the first connecting rod 601, screw 604, end cap 603, and flange 602, and reinstall screw 507, screw 504, and nut 505. Next, alternately remove the connecting components 6 on drive component b, using the same removal method as drive component a. Step 9, Dismantle the maintenance device: Measure and inspect whether the installation of the support slider 7 meets the technical requirements in Step 6. If it meets the requirements, the bottom bracket 2.1, bottom support wheel frame 1.1, side bracket 2.2 and side support wheel frame 1.2 can be disassembled and assembled; if it does not meet the requirements, repeat Steps 3 to 8. Step 10, C-type waterstop reinstallation: The mating sealing frame 4 is retracted to the position of step S1, and the C-type waterstop 8 and the upper and lower pressure plates are installed.

Next, the connecting components are alternately installed on drive component b, and the installation method is the same as that of drive component a. Step five is specifically as follows: the five sets of drive components operate simultaneously, and when the drive cylinder extends to its maximum stroke for the third time, the docking sealing frame is pushed out synchronously. At this time, the support slider has completely disengaged from the support surface of the ship lift's cabin head, and the weight of the docking sealing frame is supported by the support wheel and the rail. Step six specifically involves: removing the support slider, selecting a reference and marking it, and reinstalling and adjusting the new support slider to meet the corresponding technical requirements. Step seven specifically involves the following steps: Five sets of drive components operate simultaneously. When the drive cylinder retracts to its initial position for the first time, the sealing frame retracts synchronously. First, remove screw one between the shaped flange and bushing in drive component a, then extend the drive cylinder to its maximum stroke. Sequentially remove the second connecting rod, screw two, end cap, and shaped flange. Reinstall the shaped flange, end cap, screw two, and screw one between the shaped flange and bushing. Extend the drive cylinder to its maximum stroke and install the connecting screw between the shaped flange and bushing. Next, alternately remove the connecting components on drive component b, using the same removal method as drive component a. Step eight specifically involves the following steps: all five drive components operate simultaneously. When the drive cylinder retracts to its second position, the mating sealing frame retracts synchronously. First, remove screw one between the shaped flange and the bushing in drive component a, then extend the drive cylinder to its maximum stroke. Sequentially remove the first connecting rod, screw two, end cap, and shaped flange, and reinstall screw one, the screw rod, and the nut.
