Description

Technical Field

[0001] This invention relates to the field of weighing technology for heavy structures in marine engineering, and specifically to a modular and expandable heavy weighing platform for marine engineering. Background Technology

[0002] In the field of marine engineering, after the completion of large jacket structures, topside modules, and other structures, precise weight and center of gravity measurements are essential. This is a critical prerequisite for ensuring the safety of floating crane lifting, ship transportation, and offshore installation operations. Currently, the most commonly used weighing method is the "hydraulic jacking method": multiple support points are pre-arranged at the bottom of the structure, and a weighing unit consisting of hydraulic jacks and load cells is placed under each support point. Through synchronous jacking, the load cells bear the full load, allowing for the calculation of the total weight and center of gravity.

[0003] However, in the aforementioned routine operations, on-site engineers face a very specific and challenging problem: the platform foundations used to support and place these weighing units (usually dock floors, slipways, or barge decks) are not perfectly flat and often exhibit localized deformations, weld spatter, or debris. More critically, the bottom surfaces of the support piers (steel components used to transfer loads) at the base of large structures often have slight unevenness due to manufacturing tolerances, long-term wear, or residual welding deformation (e.g., localized bulges or depressions, with tolerances typically within ±2-5mm). When multiple independent small weighing platforms are spliced ​​together to match the complex support layout at the base of the structure, the levelness of each platform unit and the relative levelness between adjacent platforms is difficult to adjust quickly and accurately by visual inspection or conventional shims. In practice, workers have to repeatedly insert groups of metal shims of varying thicknesses and shapes under each weighing platform to achieve a rough level. This not only makes the preparation work before weighing cumbersome, time-consuming, and labor-intensive, but more seriously, the unstable gasket stack may be compressed, deformed, slipped or point-contacted under loads of hundreds or even thousands of tons, causing the sensor to be eccentric and the data to be distorted, directly damaging the reliability of the weighing results. Summary of the Invention

[0004] The purpose of this invention is to provide a modular and expandable heavy-duty weighing platform for marine engineering, which solves the problem in the prior art that the uneven ground and the bottom surface of the pier require repeated manual filling of shims for leveling, resulting in low weighing preparation efficiency and sensor distortion due to off-center load measurement.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a modular and expandable heavy-duty weighing platform for marine engineering, comprising multiple basic platform units that can be spliced ​​together or expanded and distributed at corresponding weighing positions below the jacket structure, each basic platform unit comprising:

[0006] A load-bearing base, placed on the ground;

[0007] The first load-bearing base plate is placed on top of each of the aforementioned load-bearing bases;

[0008] The displacement adjustment components are arranged around each of the first load-bearing base plates to fix the position of the first load-bearing base plates.

[0009] The second load-bearing base plate is located above the first load-bearing base plate;

[0010] Weighing jacks are installed on top of each of the second load-bearing base plates;

[0011] An angle leveling component is disposed between the first load-bearing base plate and the second load-bearing base plate, and is used to calibrate the angle of the weighing jack on the second load-bearing base plate;

[0012] A load cell is installed inside the top of the piston rod of the weighing jack;

[0013] A load-bearing base plate is installed on the top of the piston rod of the weighing jack, and the top of the load-bearing base plate is used to fit against the weighing position at the bottom of the guide frame.

[0014] Furthermore, the load-bearing base, the first load-bearing bottom plate, the second load-bearing bottom plate, and the load-bearing base plate are all steel bottom plates, among which the load-bearing base has the largest bearing area.

[0015] Furthermore, the displacement adjustment assembly consists of a mounting base, a locking screw, and a limiting plate. The mounting base is detachably mounted on the top of the load-bearing base via a first locking member and is located near the perimeter of the load-bearing base. A ball nut is provided inside the mounting base, and the locking screw passes through the ball nut and cooperates with it. The limiting plate is located at the front end of the ball nut and is rotatably connected to the ball nut.

[0016] Furthermore, the vertical cross-section of the limiting plate is an inverted L-shape, and the L-shaped opening of the limiting plate faces the first load-bearing base plate. The side wall of the vertical section of the limiting plate is in contact with the side wall of the first load-bearing base plate, and a rotating handle is installed at the other end of the locking screw.

[0017] Furthermore, the angle leveling assembly consists of a support column, a leveling sphere, a hydraulic lifting component, an overlap plate, and a ball joint. The support column is fixedly connected to the top of the first load-bearing base plate, and a support groove is formed on the top of the support column. The support groove is a spherical groove, and the leveling sphere is placed on the spherical groove. The area of ​​the spherical groove is less than half the area of ​​the outer sphere of the leveling sphere. The overlap plate is fixedly installed on the bottom of the second load-bearing base plate, and an overlap groove is formed on the bottom surface of the overlap plate that movably fits the outer surface of the leveling sphere.

[0018] Furthermore, symmetrical retaining rings are provided on the top ring wall of the bearing column. The retaining rings are detachably installed on the top of the bearing column by means of a second locking member. The cross-section of the retaining ring is arc-shaped, and the inner wall of the arc shape fits against the outer spherical wall of the leveling ball. The top of the retaining ring is located above the center of the leveling ball and below the bottom surface of the overlapping plate. The hydraulic lifting member is vertically fixedly installed on the top of the first load-bearing base plate and is located on the outside of the bearing column in a ring distribution. The bottom of the ball joint is installed inside the top of the piston rod of the hydraulic lifting member, and the top is installed on the bottom of the second load-bearing base plate, so that the second load-bearing base plate can be angled around the leveling ball.

[0019] Furthermore, an electronic level is installed on the top of the second load-bearing base plate, a receiving groove is installed on the top of the piston rod of the weighing jack, the weighing sensor is placed in the receiving groove, the electronic level and the weighing sensor are connected to an external monitoring device through wires, and a mating part is integrally formed on the bottom of the load-bearing base plate, the mating part is placed in the receiving groove and fits against the weighing sensor.

[0020] Furthermore, through holes are formed near the four corners of the load-bearing base plate, and vertical support columns are installed on the top of the second load-bearing base plate. When the load-bearing base plate and the guide frame are in close contact to bear the load, the top of the support column is located below the through holes.

[0021] Furthermore, it also includes pads, the number of which is multiple and of different heights. Each pad has a guide groove symmetrically formed thereon. The width of the guide groove matches the diameter of the support column, and the length of the guide groove is not less than the center-to-center distance between two adjacent support columns.

[0022] Compared with existing technologies, this invention provides a modular and expandable heavy-duty weighing platform for marine engineering. By incorporating displacement adjustment components in each basic platform unit, operators can quickly position and lock the first load-bearing base plate on the load-bearing pedestal, eliminating the tedious process of repeatedly adjusting the base plate position. Simultaneously, an angle leveling component is integrated between the first and second load-bearing base plates. When the weighing jack above the second load-bearing base plate deviates from its vertical position due to the tilt of the support surface, this component can calibrate the angle of the second load-bearing base plate, automatically adjusting the force direction of the weighing jack to a reasonable range. Therefore, precise horizontal and angular adjustments can be achieved without manually inserting multiple layers of shims under the platform, effectively avoiding sensor off-center loading problems caused by shim compression deformation or slippage. This ensures that the weighing sensor operates only under axial pressure, improving the reliability of weighing data, reducing the risk of sensor damage, and shortening the preparation time before weighing.

[0033] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] As attached Figure 1 To be continued Figure 7 As shown:

[0035] Example 1:

[0036] This invention provides a modular and expandable heavy-duty weighing platform for marine engineering. The platform comprises multiple basic platform units, which can be spliced ​​together to form a continuous support surface, or distributed and dispersed at corresponding weighing positions below the jacket, depending on the actual distribution of the support pads at the bottom of the jacket. Each basic platform unit, as an independent working module, possesses complete load transfer and attitude adjustment functions.

[0037] like Figure 1 and Figure 2 As shown, each basic platform unit includes, from bottom to top: a load-bearing base 1, a first load-bearing base plate 2, a second load-bearing base plate 3, a weighing jack 4, and a load-bearing base plate 6.

[0038] The load-bearing base 1 is placed directly on a supporting foundation such as the dock floor, slipway, or barge deck. The load-bearing base 1 adopts a steel base plate structure with a large bottom surface area, which helps to distribute the load transmitted from above to the ground, reducing the pressure on the local ground. On top of each load-bearing base 1, a first load-bearing base plate 2 is placed, also made of steel, serving as the installation foundation for the upper structure.

[0039] In order to quickly and accurately lock the horizontal position of the first load-bearing base plate 2 on the load-bearing base 1, each basic platform unit also includes a displacement adjustment component.

[0040] like Figure 2As shown, the displacement adjustment assembly is disposed around each of the first load-bearing base plates 2. Specifically, the displacement adjustment assembly consists of a mounting base 7, a locking screw 8, and a limiting plate 9. The mounting base 7 is detachably mounted on the top of the load-bearing base 1 by a first locking member 10 (e.g., a high-strength bolt), and the mounting base 7 is positioned close to the perimeter of the load-bearing base 1. A ball nut is pre-installed inside the mounting base 7, and the locking screw 8 passes through the ball nut and forms a helical drive engagement with it.

[0041] The limiting plate 9 is located at the front end of the ball nut and is rotatably connected to it. With this structure, when the operator rotates the locking screw 8, the ball nut drives the limiting plate 9 to move towards the side wall of the first load-bearing base plate 2 until the first load-bearing base plate 2 is firmly positioned. This displacement adjustment component allows on-site personnel to quickly align and fix the first load-bearing base plate 2 on the load-bearing base 1 without the need for external measuring tools. In the initial adjustment state, the position of the first load-bearing base plate 2 can be adjusted, avoiding the time-consuming process of repeatedly moving the base plate in traditional methods, thus improving the efficiency of pre-weighing preparation.

[0042] Furthermore, in order to enhance the reliability of the constraint on the first load-bearing base plate 2, such as Figure 2 As shown, the vertical section of the limiting plate 9 is designed as an inverted L-shape. The opening of this L-shaped plate faces the first load-bearing base plate 2. When the locking screw 8 is screwed in, the vertical section of the limiting plate 9 fits against the side wall of the first load-bearing base plate 2, while the horizontal section of the L-shape presses down on the edge of the first load-bearing base plate 2 from above, thereby simultaneously restricting the displacement of the first load-bearing base plate 2 in both the horizontal and vertical directions, preventing accidental movement during subsequent leveling or weighing. In addition, for convenient on-site operation, a rotating handle 11 is installed at the end of the locking screw 8 away from the limiting plate 9, allowing workers to manually complete the locking operation without the need for additional tools.

[0043] like Figure 1 and Figure 3 As shown, a second load-bearing base plate 3 is provided above the first load-bearing base plate 2. An angle leveling component is installed between the first load-bearing base plate 2 and the second load-bearing base plate 3. This angle leveling component is used to calibrate the angle of the second load-bearing base plate 3 and the weighing jack 4 above it to compensate for the posture deviation caused by the tilt of the load-bearing base 1 or uneven ground.

[0044] Specifically, please refer to Figure 3 , Figure 4 and Figure 5The angle leveling assembly consists of a support column 12, a leveling ball 13, a hydraulic lifting component 14, an overlapping plate 15, and a ball joint 16. The support column 12 is fixedly connected to the top central area of ​​the first load-bearing base plate 2. A support groove 17, which is spherical, is machined on the top of the support column 12. The leveling ball 13 is placed on the support groove 17, and the spherical area of ​​the support groove 17 is designed to be less than half the area of ​​the outer sphere of the leveling ball 13. This allows the leveling ball 13 to sit stably in the support groove 17 while allowing it to swing freely within a certain angle range. The overlapping plate 15 is fixedly installed on the bottom of the second load-bearing base plate 3. An overlapping groove 26 is machined on the bottom surface of the overlapping plate 15. The inner wall of the overlapping groove 26 is in movable contact with the outer surface of the leveling ball 13, thus forming a ball-joint-like connection, allowing the second load-bearing base plate 3 to be tilted relative to the first load-bearing base plate 2 in multiple directions.

[0045] To ensure that the leveling ball 13 does not fall off the top of the supporting column 12, while not restricting its swing ability, such as Figure 4 As shown, retaining rings 18 are symmetrically arranged on the top annular wall of the support column 12. The retaining rings 18 are detachably installed on the top of the support column 12 via a second locking element 19 (e.g., an internal hex bolt). The cross-section of the retaining rings 18 is arc-shaped, and the inner wall of this arc fits against the outer spherical wall of the leveling ball 13. After assembly, the top of the retaining rings 18 is located above the center of the leveling ball 13 and below the bottom surface of the overlapping plate 15. This arrangement ensures that the leveling ball 13 is both constrained within the support groove 17 by the retaining rings 18 and has sufficient space for swinging, thus guaranteeing the flexibility of angle adjustment. By employing a detachable retaining ring structure, field personnel can replace retaining rings 18 of different sizes or wear levels as needed, helping to reduce maintenance costs after long-term use.

[0046] As the power source driving the angle change of the second load-bearing base plate 3, the hydraulic lifting component 14 is vertically fixedly installed on the top of the first load-bearing base plate 2, and multiple hydraulic lifting components 14 are evenly distributed in a ring around the outer side of the bearing column 12. Each hydraulic lifting component 14 can be a small hydraulic cylinder. The bottom of the ball joint 16 is installed inside the top of the piston rod of the hydraulic lifting component 14, and the top of the ball joint 16 is installed on the bottom of the second load-bearing base plate 3. Since the ball joint 16 can transmit push and pull forces while allowing a certain degree of deflection, when the hydraulic lifting components 14 at different positions extend and retract to different heights, the second load-bearing base plate 3 can adjust the pitch and roll angles around the center of the leveling ball 13. This angle leveling component does not require manual insertion of shims under the platform, but achieves precise angle calibration by actively adjusting the stroke of the hydraulic lifting component 14. This avoids the risk of compression deformation or slippage of multiple shims under heavy load, and helps to ensure that the load cell 5 is always in an ideal axial compression state during subsequent weighing, thereby improving the reliability of the weighing data.

[0047] In order to obtain real-time information on the horizontal status of the second load-bearing base plate 3 and provide feedback for angle adjustment, such as Figure 6 As shown, an electronic level 20 is installed on the top of the second load-bearing base plate 3. The electronic level 20 is capable of measuring the two-dimensional tilt angle data of the second load-bearing base plate 3 relative to the absolute horizontal plane.

[0048] Weighing jacks 4 are installed on the top of the second load-bearing base plate 3. The weighing jacks 4 are arranged in a predetermined layout in the middle of the second load-bearing base plate 3. A receiving groove 21 is formed inside the top of the piston rod of each weighing jack 4. A load cell 5 is placed in this receiving groove 21. The load cell 5 can be a column-type or spoke-type high-precision pressure sensor, used to convert the load borne by the hydraulic jack into an electrical signal.

[0049] The load-bearing base plate 6 is mounted on top of the piston rod of the weighing jack 4, and its top surface is designed to mate with the support pad at the bottom of the guide frame to transfer the load. Specifically, the bottom of the load-bearing base plate 6 has an integrally formed mating portion 601, the shape of which matches the receiving groove 21. During installation, the mating portion 601 is placed in the receiving groove 21, and its lower end face mates with the upper end face of the load cell 5. This design ensures that the pressure transmitted from the guide frame acts directly on the sensing surface of the load cell 5 through the load-bearing base plate 6, reducing intermediate links in the force transmission path and improving measurement accuracy. The electronic level 20 and each load cell 5 are interconnected with external monitoring equipment (such as a computer or dedicated weighing instrument) via wires to achieve centralized data acquisition and real-time display.

[0050] As a safety protection structure, such as Figure 6As shown, the load-bearing base plate 6 has through holes 22 near its four corners. Simultaneously, a vertical support column 23 is mounted on the top of the second load-bearing base plate 3. When the weighing jack 4 is in normal weighing mode, the top of the support column 23 is below the through holes 22, and the two do not contact each other. If, during the weighing process, the load-bearing base plate 6 moves excessively downward due to hydraulic system failure or overload, the top of the support column 23 will enter the through hole 22 and eventually press against the load-bearing base plate 6, forming a mechanical hard limit, thereby preventing the load cell 5 from being excessively compressed and damaged. This mechanical limit structure provides physical protection for the expensive load cell 5, helping to reduce the risk of equipment damage in unexpected situations.

[0051] In addition, the cooperation between the through hole 22 and the support column 23 provides another active adjustment function: when the on-site personnel find that the piston rod stroke of the weighing jack 4 is insufficient to make the load-bearing plate 6 effectively contact the support pad at the bottom of the guide frame, the piston rod of the weighing jack 4 can be actively lowered through external monitoring equipment, so that the load-bearing plate 6 is lowered synchronously.

[0052] During this process, the support column 23 moves upward relative to the through hole 22 until the top of the support column 23 passes through the through hole 22 and finally comes into contact with the lower surface of the support pad at the bottom of the guide frame. At this time, the support column 23 temporarily replaces the weighing jack 4, forming a rigid support for the guide frame. In this state, the operator can insert a pad 24 of appropriate height between the top of the load-bearing base plate 6 and the guide frame support pad according to the gap data measured on site (the specific structure and usage of the pad 24 will be detailed in Embodiment 2). When the pad 24 is inserted, the guide groove 25 on the pad 24 passes through the corresponding support column 23, allowing the pad 24 to be smoothly moved to the predetermined position on the top of the load-bearing base plate 6. After the pad 24 is placed, the piston rod of the weighing jack 4 is driven to rise again, so that the load-bearing base plate 6 bears the load again. At this time, the pad 24 is clamped between the load-bearing base plate 6 and the guide frame support pad, effectively increasing the overall support height of the weighing platform. This process does not require disassembling any components of the basic platform unit. Even when the piston rod of the weighing jack 4 has reached its maximum mechanical limit, on-site personnel can still easily add pads 24 through the above operation, thereby expanding the height adaptability range of the weighing platform.

[0053] With the above structure, the modular and expandable heavy-duty weighing platform for marine engineering in this embodiment can achieve the following working processes:

[0054] First, according to the distribution of the support pads at the bottom of the jacket, multiple load-bearing bases 1 are placed in place on the working ground. Then, a first load-bearing base plate 2 is placed on each load-bearing base 1. By operating the rotating handle 11 of the displacement adjustment component, the locking screw 8 drives the limit plate 9 to lock the first load-bearing base plate 2 in the center of the load-bearing base 1.

[0055] Next, the angle leveling assembly is activated. The operator reads data from the electronic level 20 via external monitoring equipment to determine the current posture of the second load-bearing base plate 3. If tilting is present, the hydraulic lifting components 14 at different positions are controlled to extend and retract, driving the second load-bearing base plate 3 to swing around the leveling ball 13 until the electronic level 20 indicates that the second load-bearing base plate 3 is in a horizontal state. During this process, the leveling ball 13 rolls freely between the bearing groove 17 and the overlapping plate 15, while the retaining ring 18 ensures that it will not come out.

[0056] After leveling, the support pads of the jacket structure are slowly lowered onto the load-bearing base plates 6 of each basic platform unit. The load is transferred to the load cells 5 through the load-bearing base plates 6, and external monitoring equipment records the readings of all load cells 5. Simultaneously, the weighing jacks 4 apply a lifting force, causing the support pads to lift off the ground. At this point, all the load is borne entirely by the load cells 5. By summing the values ​​from each sensor and calculating the center of gravity, the total weight and center of gravity of the jacket structure can be obtained. Throughout the weighing process, the support column 23 remains at a certain distance below the through hole 22 and does not participate in load bearing; it only serves a protective function in case of overtravel.

[0057] Example 2:

[0058] This embodiment, based on Embodiment 1, further provides an adaptive adjustment structure for different working conditions at different heights. Specifically, this embodiment focuses on describing the usage of the pad 24.

[0059] Please see Figure 7 Because the height of the support pads at the bottom of different guide frames may vary, or the required support height may differ at different support points of the same guide frame due to ground settlement, the stroke of the weighing jack 4 alone may not be sufficient to ensure a good fit between the load-bearing base plate 6 and the support pads in all working conditions. Therefore, the weighing platform in this embodiment also includes pads 24. There are multiple pads 24, and each pad 24 has a different height (i.e., thickness), for example, it can be set to various specifications such as 20mm, 50mm, and 100mm.

[0060] The pad 24 is used as follows: When on-site personnel find, based on actual measurements, that the piston rod stroke of the weighing jack 4 is insufficient to allow the load-bearing base plate 6 to effectively contact the support pad at the bottom of the guide frame, it is not necessary to disassemble any components of the basic platform unit. The operator first controls the piston rod of the weighing jack 4 to actively descend via external monitoring equipment, causing the load-bearing base plate 6 to descend synchronously. During this descent, the support column 23 moves upward relative to the load-bearing base plate 6 until the top of the support column 23 passes through the through hole 22 on the load-bearing base plate 6 and comes into contact with the lower surface of the support pad at the bottom of the guide frame. At this point, the support column 23 temporarily replaces the weighing jack 4, providing rigid support to the guide frame.

[0061] With the jacket temporarily supported by the support columns 23, the operator measures the current gap between the upper surface of the load-bearing base plate 6 and the lower surface of the bottom support pad of the jacket. Based on this gap value and the required final support height, one or more pads 24 of suitable total thickness are selected. Then, the guide groove 25 on the pad 24 is aligned with the corresponding support column 23, so that the guide groove 25 fits into the support column 23. Since the length of the guide groove 25 is not less than the center-to-center distance between two adjacent support columns 23, the operator can smoothly move the pad 24 along the guide direction of the support column 23, so that the pad 24 is moved as a whole to a predetermined position above the top of the load-bearing base plate 6. At this time, the pad 24 is located in the gap formed between the load-bearing base plate 6 and the jacket support pad.

[0062] After the pad 24 is placed, the operator again controls the piston rod of the weighing jack 4 to rise via external monitoring equipment. The load-bearing base plate 6 rises accordingly, its top contacting the lower surface of the pad 24, pushing the pad 24 upwards until its upper surface is tightly fitted against the lower surface of the guide frame support pad. During this process, the top of the support column 23 gradually withdraws from the through hole 22, returning to its initial state below the through hole 22 and no longer bearing any support. At this point, the entire load is again transferred to the load cell 5 through the load-bearing base plate 6 and the pad 24. The pad 24 is reliably clamped between the load-bearing base plate 6 and the guide frame support pad, effectively increasing the overall support height of the weighing platform.

[0063] The above operation process does not require disassembling the weighing jack 4, the load-bearing base plate 6, or any other components. Even when the piston rod of the weighing jack 4 has reached its maximum mechanical limit, on-site personnel can still easily add the pad 24 through the above steps, thereby expanding the height adaptability range of the weighing platform. Meanwhile, when the weighing jack 4 is working normally, the pad 24 maintains a stable position through the cooperation of the guide groove 25 and the support column 23, preventing lateral slippage. When it is necessary to replace the pad 24 with one of different thicknesses or to end the weighing operation, simply reverse the operation: control the weighing jack 4 to descend, allowing the support column 23 to pass through the through hole 22 again and press against the guide frame, making it easy to remove or replace the pad 24.

[0064] The remaining structure and working process of this embodiment are the same as those of embodiment one, and will not be described again here.

[0065] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
