Abstract
Description
Technical Field
[0001] This utility model relates to the field of dredging equipment technology, and in particular to a heavy-duty leveling device for high-horsepower tugboats. Background Technology
[0002] While self-propelled trailing suction hopper dredgers, widely used in the dredging industry, can effectively remove seabed sediments, they often leave uneven ridges and trenches on the seabed due to various factors such as water flow and geological conditions. This phenomenon not only affects the quality of subsequent construction but also increases the difficulty of construction. The traditional approach is to use trailing suction hopper dredgers for shallowing operations when the project is nearing completion. However, due to the characteristics of trailing suction hopper dredgers themselves, this method is inefficient, time-consuming, and increases the cost of the entire project. Therefore, a heavy-duty leveling device for high-horsepower tugboats is needed.
[0003] A search revealed Chinese patent publication number CN109098224A. This invention belongs to the field of environmental dredging, and specifically relates to a heavy-duty leveling device for high-horsepower tugboats. The main structure of the heavy-duty leveling device for high-horsepower tugboats is a frame structure, which is divided into several cavities by several longitudinal partitions. Each cavity is equipped with a cutter frame with a cutter blade. The cavity is flared, with the front opening larger than the rear opening. An integral arc-shaped scraper is provided at the rear of the cavity. The frame structure is divided into six cavities by seven longitudinal partitions. Support trusses and support steel pipes are located above the cavities. This invention provides a heavy-duty leveling device for high-horsepower tugboats with a large lateral width, which increases the working surface width and improves the dredging efficiency. By optimizing the structural form, the overall rigidity of the heavy-duty leveling device is improved, avoiding the problems of front-end clogging and passive scraper sinking. However, during use, due to different seabed topographic heights, the device cannot adjust the leveling device according to different heights, resulting in reduced adaptability and flexibility of the leveling device. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a heavy-duty leveling device for high-horsepower tugboats, which aims to improve the problem that existing devices cannot adjust the leveling device according to different heights due to different seabed topography, resulting in reduced adaptability and flexibility of the leveling device.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a heavy-duty leveling tool for high-horsepower tractors, comprising a housing, with multiple longitudinal partitions fixedly connected inside the housing, and a blade holder fixedly connected between adjacent longitudinal partitions. A connecting plate is provided on the left and right sides of the interior of each blade holder, and a blade is fixedly connected between adjacent connecting plates. Multiple threaded holes are provided on the left and right sides of the interior of each blade holder, and a bolt is threadedly connected between adjacent connecting plates. An arc-shaped scraper is fixedly connected to the front side of the housing, and a steel cylinder is fixedly connected to the front side of the arc-shaped scraper. A disassembly mechanism is provided between adjacent connecting plates.
[0006] The above technical solution involves adjusting the position of the connecting plate by using the threaded holes and bolts on the tool holder, thereby determining the appropriate height of the tool. The tool then cuts the soil, and the cut soil is collected by the arc-shaped scraper on the front of the outer shell and pushed to other areas. By adjusting the ballast water volume inside the steel cylinder, the overall weight distribution of the rake is changed, ensuring that the tool can continuously perform cutting operations at the optimal working angle, thus improving the adaptability and flexibility of the operation.
[0007] As a further description of the above technical solution:
[0008] The disassembly mechanism includes two connecting blocks. The right sides of the two connecting blocks are fixedly connected to the left and right sides of the cutter. Grooves are provided on the front sides of the multiple connecting blocks and the cutter. A locking block is slidably connected inside the multiple grooves. A fixing block is fixedly connected to the front side of the multiple locking blocks. Multiple bolts are threadedly connected to the front side of the multiple fixing blocks.
[0009] With the above technical solution: when the tool needs to be disassembled, rotate bolt two to disengage the locking block in the tool groove from the tool. Pull the fixing block to remove the locking block from the groove. Since the connection between the connecting block and the tool is achieved by the locking block in the groove, the connection between the connecting block and the tool is released after the locking block is successfully removed, thereby realizing the quick disassembly and replacement of the tool.
[0010] As a further description of the above technical solution:
[0011] The top of the outer shell is fixedly connected to multiple steel pipes, and the top of the multiple steel pipes is fixedly connected to a supporting truss.
[0012] The above technical solution involves fixing multiple steel pipes at the top of the outer shell to the supporting truss, allowing the entire device to be lowered into the seabed with the help of the externally bound supporting truss.
[0013] As a further description of the above technical solution:
[0014] A bracket is fixedly connected to the front side of the arc-shaped scraper, and a fixing plate is fixedly connected to the bottom of the bracket.
[0015] The above technical solution involves fixing a plate at the bottom of the support on the front side of the arc-shaped scraper to stabilize the steel cylinder and ensure that the steel cylinder can effectively adjust the settling state of the rake leveler.
[0016] As a further description of the above technical solution:
[0017] The bottom of each of the two longitudinal partitions in the middle is fixedly connected to a sliding shoe plate, and the top of each of the two sliding shoe plates is fixedly connected to the bottom of the longitudinal partition at equal intervals.
[0018] The above technical solution involves two longitudinal partitions with sliding shoe plates at their bottoms. These sliding shoe plates are fixed at equal intervals to the bottom of the longitudinal partitions, allowing them to slide smoothly in the seabed environment and assisting the entire device in stable operation within the seabed.
[0019] As a further description of the above technical solution:
[0020] A second connecting plate is fixedly connected between the two adjacent sliding shoe plates, and the second connecting plate has a smooth design.
[0021] Through the above technical solution, the connecting plate 2 between the two slipper plates enhances the integrity of the structure by fixing them together. The smooth design effectively reduces stress concentration at the connection point and improves the stability and smoothness of the structure.
[0022] As a further description of the above technical solution:
[0023] Multiple pulleys are fixedly connected to the bottom of both of the sliding shoe plates, and the outer walls of the multiple pulleys are fixedly connected to the bottom of the sliding shoe plates at equal intervals.
[0024] The above technical solution involves multiple pulleys at equal intervals on the bottom of the skid plate and tightly fixed to the skid plate, which reduces the friction with the seabed surface and makes the device move more smoothly on the seabed.
[0025] As a further description of the above technical solution:
[0026] The tops of the multiple longitudinal partitions are fixedly connected to the inner top of the outer shell at equal intervals, and the right sides of the two connecting plates are fixedly connected to the adjacent blade holders at equal intervals.
[0027] Through the above technical solution: the top of the longitudinal partition is evenly fixed to the top of the inner side of the outer shell to ensure the stability of the internal structure, and the right side of the connecting plate is also evenly fixed to the adjacent part of the tool holder to provide support for the installation and operation of the tool.
[0028] This utility model has the following beneficial effects:
[0029] 1. In this utility model, by using the threaded holes and bolts on the tool holder to adjust the position of the connecting plate, the appropriate height of the tool is determined. The tool performs cutting operations on the soil, and the cut soil is collected by the arc-shaped scraper on the front side of the outer shell and pushed to other areas. The amount of ballast water in the steel cylinder is adjusted to change the overall weight distribution of the rake, ensuring that the tool can continuously perform cutting operations at the optimal working angle, thereby improving the adaptability and flexibility of the operation.
[0030] 2. In this utility model, when the tool needs to be disassembled, rotate the second bolt to disengage the locking block in the tool groove from the tool. Pull the fixing block to remove the locking block from the groove. Since the connecting block and the tool are connected by the locking block in the groove, the connection between the connecting block and the tool is released after the locking block is successfully removed, thereby realizing the quick disassembly and replacement of the tool.

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0039] Reference Figure 1 and Figure 4 This utility model provides an embodiment of a heavy-duty leveling tool for high-horsepower tugboats, comprising a housing 1, with multiple longitudinal partitions 3 fixedly connected inside the housing 1, dividing the multiple longitudinal partitions 3 into multiple cavities, and a blade holder 4 fixedly connected between adjacent longitudinal partitions 3, with connecting plates 5 arranged on the left and right sides inside the multiple blade holders 4, and blades 6 fixedly connected between adjacent connecting plates 5, with multiple threaded holes 7 opened on the left and right sides inside the multiple blade holders 4, and bolts 8 threadedly connected between adjacent connecting plates 5. The height of the blades 6 between the connecting plates 5 can be controlled through the multiple threaded holes 7 and bolts 8, and an arc-shaped scraper 9 fixedly connected to the front side of the housing 1, which pushes the cut soil to another place. A steel cylinder 10 is fixedly connected to the front side of the arc-shaped scraper 9, and the settling state of the leveling tool can be finely adjusted by adjusting the ballast water volume in the steel cylinder 10 to maintain the optimal working angle. A disassembly mechanism 2 is provided between adjacent connecting plates 5 for easy disassembly and replacement of the blades 6.
[0040] Specifically, multiple longitudinal partitions 3 are interconnected inside the outer shell 1, dividing it into multiple independent cavities. A blade holder 4 is fixed between each of the longitudinal partitions 3. Blades 6 are connected to the connecting plates 5 on the left and right sides inside the blade holder 4. The blades 6 are used to cut soil. Multiple threaded holes 7 on the blade holder 4 cooperate with bolts 8 between the connecting plates 5 to adjust the relative position of the connecting plates 5, thereby achieving flexible control of the height of the blades 6 to adapt to different operational needs. The arc-shaped scraper 9 on the front side of the outer shell 1 can push the cut soil to other areas, ensuring a clean and efficient work area. The steel cylinder 10 on the front side of the arc-shaped scraper 9 adjusts the internal ballast water volume to adjust the settling state of the rake, keeping it at the optimal working angle.
[0041] Reference Figure 5The disassembly mechanism 2 includes two connecting blocks 201. The right sides of the two connecting blocks 201 are fixedly connected to the left and right sides of the cutter 6. Grooves 202 are provided on the front sides of multiple connecting blocks 201 and the cutter 6. A locking block 203 is slidably connected inside the multiple grooves 202. A fixing block 204 is fixedly connected to the front side of the multiple locking blocks 203. Multiple bolts 205 are threadedly connected to the front side of the multiple fixing blocks 204. By rotating the bolts 205, the locking block 203 is separated from the cutter 6, and the fixing block 204 can be pulled out, so that the locking block 203 is taken out from the groove 202, and the connecting block 201 is separated from the cutter 6.
[0042] Specifically, two connecting blocks 201 are fixed on the left and right sides of the tool 6. Grooves 202 are provided on the front side of both the connecting blocks 201 and the tool 6. A locking block 203 is slidably connected in the groove 202. Multiple bolts 205 are threaded onto the fixing block 204 on the front side of the locking block 203. When disassembly is required, the bolts 205 are rotated. As they rotate, the locking block 203 will gradually separate from the tool 6. Then the fixing block 204 can be pulled out, and the locking block 203 can be further removed from the groove 202, thus achieving the separation operation between the connecting block 201 and the tool 6.
[0043] Reference Figure 1 and Figure 2 Multiple steel pipes 11 are fixedly connected to the top of the outer shell 1. A support truss 12 is fixedly connected to the top of the multiple steel pipes 11. The support truss 12 is tied to the top, and the device is placed into the seabed. A bracket 13 is fixedly connected to the front side of the arc-shaped scraper 9. A fixing plate 14 is fixedly connected to the bottom of the bracket 13 to support the steel cylinder 10. Sliding shoe plates 15 are fixedly connected to the bottom of the two longitudinal partitions 3 in the middle. The tops of the two sliding shoe plates 15 are fixedly connected to the bottom of the longitudinal partitions 3 at equal intervals for sliding in the seabed.
[0044] Specifically, multiple steel pipes 11 on the top of the outer shell 1 are fixedly connected to the support truss 12. With the help of the externally bound support truss 12, the entire device can be lowered into the seabed. The bottom of the bracket 13 on the front side of the arc-shaped scraper 9 is fixed with a fixing plate 14 to stabilize the support steel cylinder 10 and ensure that the steel cylinder 10 can effectively adjust the sinking state of the rake leveler. The bottom of the two longitudinal partitions 3 in the middle is equipped with a sliding shoe plate 15. The sliding shoe plate 15 is fixed at equal intervals at the bottom of the longitudinal partition 3 and can slide smoothly in the seabed environment, assisting the entire device to operate stably in the seabed.
[0045] Reference Figure 2 and Figure 3A connecting plate 2 16 is fixedly connected between two adjacent sliding shoe plates 15. The connecting plate 2 16 has a smooth design to increase the connectivity between the two sliding shoe plates 15. Multiple pulleys 17 are fixedly connected to the bottom of each of the two sliding shoe plates 15. The outer walls of the multiple pulleys 17 are fixedly connected to the bottom of the sliding shoe plates 15 at equal intervals to increase the sliding force. The tops of multiple longitudinal partitions 3 are fixedly connected to the top of the inner side of the outer shell 1 at equal intervals. The right sides of the two connecting plates 1 5 are fixedly connected to the adjacent tool holders 4 at equal intervals.
[0046] Specifically, between the two slipper plates 15, the connecting plate 2 16 enhances the overall integrity by being fixedly connected. The smooth design effectively reduces stress concentration at the connection point, improving structural stability and smoothness. Multiple pulleys 17 at the bottom of the slipper plate 15 are equidistantly distributed and tightly fixed to the slipper plate 15, reducing friction with the seabed surface and making the device move more smoothly on the seabed. The top of the longitudinal partition plate 3 is evenly fixed to the top of the inner side of the outer shell 1 to ensure the stability of the internal structure. The right side of the connecting plate 1 5 is also evenly fixed to the adjacent position of the tool holder 4, providing reliable support for the installation and operation of the tool 6.
[0047] Working principle: During operation, the position of the connecting plate 5 is first adjusted using the threaded hole 7 and bolt 8 on the tool holder 4 according to the requirements, thereby determining the appropriate height of the tool 6. As the device moves in the seabed operation area, the tool 6 cuts the soil. The cut soil is collected by the arc-shaped scraper 9 on the front side of the outer shell 1 and pushed to other areas to avoid soil accumulation affecting the operation. According to the operation environment and requirements, the weight distribution of the rake leveler is changed by adjusting the ballast water volume in the steel cylinder 10 on the front side of the arc-shaped scraper 9, thereby adjusting its settling state and ensuring that the tool 6 can continue to cut at the optimal working angle.
[0048] Furthermore, firstly, when it is necessary to disassemble the tool 6, rotate the bolt 205. Due to the threaded engagement between the bolt 205 and the fixing block 204, the bolt 205 will gradually move outward, causing the locking block 203, which was originally stuck in the groove 202 of the tool 6, to slowly disengage from the tool 6. By pulling the fixing block 204 with external force, the locking block 203 can be removed from the groove 202 along the sliding path of the groove 202. Since the connecting block 201 and the tool 6 are connected by the locking block 203 in the groove 202, once the locking block 203 is successfully removed, the connection between the connecting block 201 and the tool 6 is released, thereby achieving quick disassembly and replacement of the tool 6.
[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
