Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, specifically to a flexible steel dock pier and its non-destructive dismantling method. Background Technology

[0002] During shipbuilding or repair, a number of dock blocks are typically needed to support the weight of the hull in the hull bottom area. Currently, the upper surface of the dock blocks is mainly made of wood or steel. However, because wooden dock blocks are prone to compression deformation under certain loads, rigid, adjustable steel dock blocks are usually used for support in the construction of ships with high precision requirements, such as container ships, to ensure the accuracy of the ship's construction.

[0003] At present, the application of adjustable steel dock piers only realizes the adjustment of the height of the steel dock pier using wedges. The corrosion protection of the steel dock pier can only be achieved by regularly removing rust and repairing the coating. Moreover, the steel dock pier cannot be disassembled without damage while it is in a supported state.

[0004] Considering that during the shipbuilding process in coastal docks, the steel dock blocks are easily corroded when the ship is floating in the seawater environment, requiring regular inspection and repair of the anti-corrosion coating, the amount of tooling required for coating repair and maintenance is large. Furthermore, the use of wedges to adjust the height of the steel dock blocks often leads to easy damage to the internal structure coating. Moreover, the lack of appropriate opportunities to repair the internal coating of the steel dock blocks during use results in the internal structure of the steel dock blocks becoming unusable due to corrosion caused by seawater, reducing the efficiency of the steel dock blocks and increasing the cost of shipbuilding.

[0005] At the same time, whether steel or wooden dock piers are used, when they need to be temporarily dismantled while the ship is supported, there is a problem that they cannot be dismantled without damage due to external forces. Currently, destructive dismantling is often used, which makes the dock piers unusable, resulting in waste and greatly increasing the construction cost of the ship.

[0006] Therefore, there is an urgent need to propose a non-destructive dismantling method for flexible steel dock piers under load, so as to realize the non-destructive dismantling and reuse of steel dock piers and reduce the construction cost of ships. Summary of the Invention

[0007] To address the aforementioned technical problems, this invention provides a movable steel dock pier and its non-destructive dismantling method, which enables non-destructive dismantling of movable steel dock piers under load, improves the corrosion resistance of movable steel dock piers, extends the service life of movable steel dock piers, and reduces the construction cost of ships.

[0008] The technical solution adopted in this invention is:

[0009] A movable steel dock pier includes a bottom module, a top module, an adjusting wedge, and a nylon pad.

[0010] The bottom module is a box-shaped structure with an open top, formed by a bottom plate, longitudinal panels, and transverse partitions. The longitudinal panels are trapezoidal and located on the front and rear sides of the bottom plate. The transverse partitions are U-shaped and fixed between two longitudinal panels, with a gap between the bottom of the transverse partitions and the top surface of the bottom plate. The longitudinal panels have a light-reducing hole in the middle and a drainage hole at the bottom. A wedge adjustment opening is located on the longitudinal panel near the transverse partition, inside the transverse partition, for inserting an adjustment wedge. A stainless steel pad is provided on the bottom plate below the wedge adjustment opening.

[0011] The top module is located on top of the bottom module and includes a top plate and a support and lifting part located below the top plate. The support part is located in the middle of the top plate and has a box structure with an open bottom. It includes wall panels on the front and rear sides and support plates on the left and right sides. The wall panels have an inverted U-shaped structure, and the support plates have a right-angled trapezoidal structure. The bottom end of the support plate is the hypotenuse of the right-angled trapezoid, which extends into the bottom module.

[0012] The lifting part is provided at both ends of the top plate and includes a lifting main plate, reinforcing side plates and a lifting base plate. The lifting base plate is arranged parallel to the top plate, and the lifting main plate is vertically fixed between the top plate and the lifting base plate along the length direction of the top plate. A pair of reinforcing side plates are symmetrically arranged on both sides of the lifting main plate.

[0013] The adjusting wedge is a wedge-shaped body. The slope of the top surface of the adjusting wedge is the same as the slope of the bottom end of the support plate. It is embedded in the wedge adjustment opening of the bottom module and includes an upper pad, a lower pad, and an inclined plate. The inclined plate is vertically fixed between the upper pad and the lower pad, and sealing plates are provided at both ends of the inclined plate.

[0014] The nylon pad is disposed on the top of the top module. The length and width of the nylon pad are the same as those of the top plate of the top module. A positioning groove for binding and fixing is provided at the edge of the top surface of the nylon pad.

[0015] Preferably, the support portion is provided with a connecting reinforcing plate and a triangular reinforcing plate. The connecting reinforcing plate is located at the middle position of the support portion and is fixed to the bottom surface of the top plate along the width direction of the top plate. The triangular reinforcing plate is located at both ends of the support portion, and the two right-angled sides of the triangular reinforcing plate are fixed to the inner wall of the support plate and the bottom surface of the top plate, respectively.

[0016] Preferably, the bottom end of the support plate is provided with a stainless steel panel.

[0017] Preferably, multiple welding beads are evenly arranged on the inner sidewall of the transverse partition to adjust the gap between the adjusting wedge and the top module.

[0018] Preferably, the lifting main plate and the triangular reinforcing plate are positioned opposite each other, both located in the middle of the support and arranged along the length of the top plate.

[0019] Preferably, the reinforcing side plate is provided with a circular hole for fixing the nylon pad.

[0020] Preferably, the width of the sealing plate is greater than the width of the wedge adjustment opening, which is used to limit the position of the adjustment wedge.

[0021] A non-destructive dismantling method for a movable steel dock pier, used to dismantle the movable steel dock pier as described above, wherein the movable steel dock pier is in a load-bearing state, includes the following steps:

[0022] Step 1: According to the disassembly requirements, install a steel pad assembly under the lifting part of the top module of the movable steel dock pier, and select a hydraulic jacking device accordingly.

[0023] Step 2: Place the hydraulic jacking device on the steel pad assembly. At this time, the hydraulic jacking device is located below the lifting part of the top module of the movable steel dock pier. Adjust the height of the steel pad assembly so that the gap between the hydraulic jacking device and the top module of the movable steel dock pier is less than the lifting stroke of the hydraulic jacking device.

[0024] Step 3: Control the hydraulic jacking device to lift the lifting part of the movable steel dock pier. After the lifting load of the hydraulic jacking device reaches the preset average load of the movable steel dock pier, lock the hydraulic jacking device.

[0025] Step 4: Remove the adjusting wedge support position to create a gap between the adjusting wedge and the support plate of the top module, and then unload the hydraulic jack device.

[0026] Preferably, the rated load of the single hydraulic jack is greater than 2 / 3 of the rated load of the movable steel dock pier.

[0027] The beneficial effects of this invention are as follows:

[0028] (1) The present invention proposes a flexible steel dock pier, which uses a bottom module, a top module, an adjusting wedge and a nylon pad to effectively support the hull structure. Furthermore, by opening water flow holes on the bottom module of the flexible steel dock pier, the present invention avoids corrosion caused by water accumulation in the bottom module. In addition, stainless steel pads are set on the contact surfaces of each part of the flexible steel dock pier to improve the load-bearing capacity of the structure, while also avoiding seawater corrosion and wear between the parts during the support process, thus extending the service life of the flexible steel dock pier.

[0029] (2) The present invention proposes a flexible steel dock pier, which adjusts the support height of the flexible steel dock pier by setting a wedge adjustment opening in the bottom module and setting a welding bead limiting adjustment wedge in the bottom module to adjust the contact position between the adjustment wedge and the support part of the top module.

By opening light-reducing holes on the flexible steel dock pier and optimizing the shape of each structure, the lightweight design of the flexible steel dock pier is realized, the utilization rate of the manufacturing materials is improved, and the flexible steel dock pier is easy to transport and install. In addition, by setting water flow holes on the flexible steel dock pier, the risk of the flexible steel dock pier being corroded by seawater is reduced, and the service life of the flexible steel dock pier is extended.

[0049] This invention provides a movable steel dock pier and a non-destructive dismantling method thereof. To make the objectives, technical solutions, and effects of this invention clearer and more explicit, the invention is further described in detail below. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0050] The present invention will now be described in detail with reference to the accompanying drawings:

[0051] Example 1

[0052] This embodiment proposes a flexible steel dock pier, such as... Figure 1 and Figure 2 As shown, it includes a bottom module 1, a top module 2, an adjusting wedge 3, and a nylon pad 4.

[0053] The bottom module 1 is a box-shaped structure with an open top, formed by a bottom plate 101, a longitudinal panel 102, and a transverse partition 103. Figures 3-4As shown, the longitudinal panels have a trapezoidal structure and are located on the front and rear sides of the base plate, fixedly connected to the base plate. The transverse partition is fixed between the two longitudinal panels and welded to them. There is a certain gap between the bottom of the transverse partition and the top surface of the base plate. To save on manufacturing materials and reduce the overall weight of the bottom module while meeting the support strength requirements, the transverse partition is designed with a U-shaped structure. A weight-reducing hole 105 is provided in the middle of the longitudinal panel. This weight-reducing hole not only reduces the weight of the bottom module but also serves as an adjustment hole for forklift transportation, meeting the transfer requirements of the flexible steel dock pier. Furthermore, to prevent corrosion caused by prolonged water accumulation inside the bottom module, a drainage hole 106 is provided at the bottom of the longitudinal panel. Furthermore, in order to adjust the height of the flexible steel dock pier, the longitudinal panel is provided with a wedge adjustment opening 107 near the transverse partition. The wedge adjustment opening is located inside the transverse partition and is used to embed the adjustment wedge. A stainless steel pad 104 is fixed on the bottom plate below the wedge adjustment opening to enhance the support strength of the bottom module.

[0054] Meanwhile, in order to ensure the alignment gap between the adjusting wedge and the top module when the adjusting wedge is embedded in the adjusting hole, and to ensure that the top surface of the adjusting wedge in the bottom module is in contact with the bottom surface of the top module, this embodiment also evenly installs multiple welding beads 108 with a diameter of 20mm and a height of 5mm on the inner side of the transverse partition. These are used to adjust the alignment gap between the adjusting wedge and the top module. By moving the adjusting wedge, the support height of the movable steel dock is adjusted, and the top surface of the adjusting wedge contacts the bottom surface of the top module, thereby effectively ensuring the support load of the movable steel dock.

[0055] The top module 2 is as follows Figures 5-7 As shown, the top of the bottom module includes a top plate 201 and a support and lifting section disposed below the top plate.

[0056] Furthermore, the support portion is located in the middle of the top plate and includes wall panels 209 on the front and rear sides and support plates 208 on the left and right sides. Specifically, the support portion is a box structure with an open bottom, formed by the wall panels on the front and rear sides, the support plates on the left and right sides, and the top plate. The front and rear wall panels, the left and right support plates, and the top plate are welded together. The wall panels have an inverted U-shaped structure, and the support plates have a right-angled trapezoidal structure. The top of the support plate is the right-angled side of the right-angled trapezoid, and the bottom is the hypotenuse of the right-angled trapezoid. The bottom of the support plate extends into the bottom module and connects with the adjusting wedge embedded in the adjusting opening of the wedge block in the bottom module. To enhance the supporting capacity of the support plate, a stainless steel panel 207 is also provided at the bottom of the support plate. Meanwhile, in order to enhance the support strength of the top module, a connecting reinforcing plate 202 and a triangular reinforcing plate 203 are provided inside the support part. Specifically, the connecting reinforcing plate is located at the middle position of the support part and is fixed to the bottom surface of the top plate along the width direction of the top plate to enhance the support strength at the middle position of the support part; the triangular reinforcing plate is located at both ends of the support part, respectively close to the left and right support plates and perpendicular to the middle position of the support plates. One right-angled side of the triangular reinforcing plate is fixed to the inner wall of the support plate, and the other right-angled side is fixed to the bottom surface of the top plate.

[0057] Furthermore, the lifting section is disposed on both sides of the support section and located at both ends of the top plate, including a lifting main plate 204, reinforcing side plates 205, and a lifting base plate 206. The lifting base plate is disposed parallel to the top plate, and the lifting main plate is vertically fixed between the top plate and the lifting base plate along the length direction of the top plate. The top end of the lifting main plate is fixed to the top surface, and the bottom end is fixed to the lifting base plate. The position of the lifting main plate is opposite to the position of the triangular reinforcing plates installed on the left and right support plates inside the support section. A pair of reinforcing side plates are symmetrically disposed on both sides of the lifting main plate. The reinforcing side plates are provided with circular holes for fixing nylon pads. The reinforcing side plates and the lifting main plate together form a cross structure, which enhances the load-bearing capacity of the lifting section.

[0058] In this embodiment, in order to ensure that the top module can be smoothly inserted into the bottom module, the top module is first positioned during the installation process. The positioning is controlled by negative tolerance. The bottom end of the support part of the top module is aligned with the stainless steel pad below the wedge adjustment opening in the bottom module, and the support part of the top module is inserted into the bottom module.

[0059] The adjusting wedge 3 is a wedge-shaped body, such as Figure 8As shown, the adjusting wedge is embedded in the wedge adjustment opening of the bottom module. Its top surface slope is the same as the slope of the bottom end of the support plate, satisfying the self-locking property of steel friction, preventing slippage due to vertical force. Specifically, the adjusting wedge includes an upper pad 302, a lower pad 303, and an inclined plate 301. The inclined plate is vertically fixed between the upper and lower pads. The upper, lower, and inclined plates have the same width and are ground smooth with no protruding structures. The slope of the top surface of the upper pad is the same as the slope of the bottom end of the support plate, allowing the bottom of the top module support to fully contact the top surface of the adjusting wedge, thus adjusting the height of the top module. Furthermore, to limit the position of the adjusting wedge and prevent it from sliding out of the wedge adjustment opening, sealing plates 304 are provided at both ends of the inclined plate. The width of the sealing plates is greater than the width of the wedge adjustment opening in the bottom module, sealing both ends of the inclined plate.

[0060] The nylon pad 4, as shown Figures 9-10 As shown, the length and width of the nylon pad are the same as the top plate of the top module, and it is set on the top of the top module. The top edge of the nylon pad is provided with a positioning groove 401 for binding and fixing.

[0061] In this embodiment, the installation of the movable steel dock pier is carried out by first installing the bottom module, then embedding the adjusting wedge into the wedge adjustment opening of the bottom module, installing the top module after installing the adjusting wedge, and after the top module is installed, installing the nylon pad and laying a plastic film on it, then binding and fixing the nylon pad to the top of the top module, and laying a plastic film on it to complete the installation of the movable steel dock pier.

[0062] Example 2

[0063] In this embodiment, the flexible steel dock pier described in Embodiment 1 is applied to support the hull structure 5. The method of using the flexible steel dock pier is as follows:

[0064] First, determine the support positions of the movable steel dock piers according to the dock pier design scheme, such as... Figure 11 As shown, the movable steel dock piers are positioned according to their locations. The adjusting wedges are then adjusted to ensure the upper surface of the movable steel dock piers is level, and a protective plastic film is applied to the hull plating coating. Finally, the hull structure is hoisted or relocated to the support area of ​​the movable steel dock piers, as shown. Figure 12 As shown, after adjusting the positioning attitude of the hull structure to meet the precision control requirements, the adjusting wedge is fixed, and the additional supporting force structure on the hull structure is removed, so that the movable steel dock pier is fully supported.

[0065] To prevent damage to the protective coating at the junction of the adjusting wedge and the top module support when adjusting the height of the movable steel dock pier, which could expose the steel due to friction and lead to corrosion during the ship's undocking or floating phases, causing the adjusting wedge to rust and stick to the bottom and top modules and become unusable, this embodiment uses stainless steel pads installed on the load-bearing support surfaces of the adjusting wedge and the bottom and top modules. This effectively avoids friction between the adjusting wedge and the bottom and top modules during use. Furthermore, stainless steel is less prone to corrosion, significantly improving the corrosion resistance of the movable steel dock pier.

[0066] Example 3

[0067] This embodiment proposes a non-destructive dismantling method for movable steel dock piers. When using movable steel dock piers as described in Embodiment 1 to support the ship's hull structure, the movable steel dock piers are placed on the support pier 6. The non-destructive dismantling of the movable steel dock piers under load includes the following steps:

[0068] Step 1: According to the disassembly requirements, a steel pad assembly 7 is installed below the lifting part of the top module of the movable steel dock pier, and a hydraulic jacking device 8 is selected in conjunction. The rated load of a single hydraulic jacking device is greater than 2 / 3 of the rated load of the movable steel dock pier.

[0069] Step 2: Place the hydraulic jacking device on the steel pad assembly. At this time, the hydraulic jacking device is located below the lifting part of the top module of the movable steel dock pier. Adjust the height of the steel pad assembly so that the gap between the hydraulic jacking device and the top module of the movable steel dock pier is less than the lifting stroke of the hydraulic jacking device. Figure 13 As shown.

[0070] Step 3: Control the hydraulic jacking device to lift the lifting section of the movable steel dock pier. Once the lifting load of the hydraulic jacking device reaches the preset average load capacity of the movable steel dock pier, lock the hydraulic jacking device. Figure 14 As shown.

[0071] Step 4: Use a sledgehammer or auxiliary device to knock the adjusting wedge out of its supporting position to relieve the force. Figure 15 As shown, after creating a gap between the adjusting wedge and the support plate of the top module, the hydraulic jacking device is unloaded, leaving sufficient space between the upper surface of the movable steel dock pier and the hull structure, such as... Figure 16 As shown, this facilitates inspection and operation.

[0072] In summary, the present invention proposes a compact, high-strength, seawater-corrosion-resistant, high-load-bearing, and easily adjustable movable steel dock pier. Furthermore, a non-destructive disassembly method is proposed to complement this movable steel dock pier, enabling non-destructive disassembly of the pier while it is under load. This avoids damage to the pier during disassembly, allows for the recycling of the movable steel dock pier, extends its service life, and effectively reduces shipbuilding costs.

[0073] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
