Description

Technical Field

[0001] This invention relates to the technical field of port and waterway engineering, and in particular to a rock-throwing device for coastal high-pile wharves and its installation method. Background Technology In the construction of coastal high-pile wharves, riprap placement is a crucial step in ensuring the stability of the wharf structure and resisting wave erosion. However, the narrow space created by the superstructure (such as the upper load-bearing system composed of beams and panels) makes it difficult for traditional riprap placement equipment to operate directly. In current construction, manual transfer and placement or small vessels are often used to assist in the placement of riprap in the revetment area below the superstructure (especially in the gaps between the pile foundations at the wharf's edge and the underwater revetment area). Manual transport is extremely inefficient, with a single shift handling capacity of less than 20 cubic meters. Furthermore, it is limited by the experience and physical strength of the workers, resulting in poor uniformity and low positioning accuracy in rock placement. Small vessels are susceptible to collisions under high-pile wharves due to the spacing between wharf piles and tidal influences. Rock-throwing equipment struggles to precisely control the rock placement, often leading to localized accumulation or missed placement on the revetment structure, affecting the overall stability of the wharf. Land-based mechanical rock-throwing, such as using excavators and loaders, is limited by the upper sheltering structure of the wharf, resulting in insufficient range and angle of motion for the robotic arms. This prevents them from reaching the critical areas beneath the sheltering structure, limiting their application to a limited area at the wharf's edge and hindering comprehensive and effective revetment rock-throwing construction. As coastal wharves become larger and deeper, the construction space for revetments beneath the upper sheltering structure is increasingly confined, making traditional methods insufficient to meet the requirements of efficient and precise construction. Summary of the Invention

Baffles are provided on both sides of the second conveyor belt, with two baffles located on both sides of the multiple L-shaped partitions respectively. A pulley group is provided at the bottom of the second telescopic frame, and the pulley group is connected to the third conveying mechanism.

[0008] Furthermore, the third conveying mechanism is provided with grooves on both sides, the pulley group is disposed in the grooves, and the pulley group is provided with a detector.

[0009] Furthermore, the third conveying mechanism includes a third telescopic frame, on which a third driving mechanism and a third conveyor belt are provided.

[0010] Furthermore, the third telescopic frame is equipped with a sonar, a camera, and a lighting device, with the sonar located at the bottom of the third telescopic frame.

[0011] Furthermore, both sides of the first telescopic frame and the third telescopic frame are provided with lateral stops.

[0012] Furthermore, the coastal high-pile wharf rock-throwing device also includes a control module, and the first conveying mechanism, the second conveying mechanism, and the third conveying mechanism are all connected to the control module.

[0013] Furthermore, the present invention also provides a method for installing a rock-throwing device at a coastal high-pile wharf, characterized by comprising the following steps: Step S1: The first conveying mechanism is hoisted to the predetermined position on the surface of the wharf using hoisting equipment, and an inverted trapezoidal funnel is installed at the front end of the first conveying mechanism; wherein, the position and extension length of the first conveying mechanism can be adjusted according to the site conditions; Step S2: The second conveyor mechanism is vertically installed at the front edge of the wharf using hoisting equipment and connected to the first conveyor mechanism; wherein, the second conveyor mechanism can adjust the telescopic conveying length according to the water surface conditions; Step S3: The third conveyor mechanism is hoisted to the water surface below the dock using hoisting equipment, so that the third conveyor mechanism floats steadily on the water surface, and the third conveyor mechanism is connected to the second conveyor mechanism; wherein, the position, angle and extension length of the third conveyor mechanism can be adjusted according to the position of the stone being thrown.

[0014] The beneficial effects of this invention are as follows: 1. Strong spatial adaptability: Through the cooperation of the three-stage conveyor mechanism, it can traverse the narrow space formed by the upper sheltered structure of the wharf, enabling rock-throwing operations in areas that are difficult to reach by traditional methods, such as the gaps between pile foundations at the wharf's front edge and behind the sheltered area. The movement and extension functions of the first conveyor mechanism allow it to operate flexibly on wharves with different frame and surface layer lengths; the vertical extension and extension of the second conveyor mechanism adapts to tidal changes; the swinging and extension functions of the third conveyor mechanism enable all-round, blind-angle rock-throwing, greatly expanding the construction range. 2. High Rock Throwing Accuracy: Sonar detects underwater topography and pile foundation locations in real time, while cameras and lighting provide clear operational images, allowing operators to accurately monitor the rock throwing area. The precise design and stable operation of the three-stage conveying mechanism, along with the L-shaped baffles, barriers, and lateral blocks, ensures orderly and stable rock transport.

Compared to existing technologies, rock throwing accuracy is significantly improved, effectively enhancing the quality of bank protection projects. 3. High construction efficiency: The mechanized three-stage conveyor system operates continuously, replacing traditional manual or intermittent mechanical operations. After an excavator or crawler crane feeds stones into the hopper, the stones are automatically and quickly transported and thrown via the conveyor belt, reducing manual intervention and equipment adjustment time. The conveyor belt's movement, extension, and oscillation functions can quickly adapt to different construction locations and working conditions, enabling rapid site transfers and continuous construction, significantly improving construction efficiency, increasing single-shift workload, effectively shortening the construction cycle, and reducing project costs. 4. Excellent Safety Performance: Most operations are completed remotely, eliminating the need for operators to enter hazardous construction areas and reducing safety risks such as falling rocks, drowning during water operations, and mechanical collisions. The baffles, side blocks, and L-shaped dividers on both sides of the conveyor belt effectively prevent stone leakage and falling, ensuring the safety of construction personnel and equipment. The equipment's stability and reliability design, along with the application of a debugging and monitoring system, further enhances the safety of the construction process and reduces the probability of accidents. 5. Excellent Applicability and Economy: The rock-throwing device is suitable for the construction of coastal high-pile wharves of different scales and structures. By adjusting the parameters of the conveyor belt and the installation method, it can meet diverse construction needs. Its efficient and precise construction characteristics reduce material waste and subsequent maintenance costs; the mechanized and automated operation mode reduces labor costs and equipment wear and tear, demonstrating good economic efficiency and application value, and bringing significant economic and social benefits to the wharf construction industry.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0022] like Figures 1 to 10 As shown, in this embodiment, the present invention includes a first conveying mechanism 1, a second conveying mechanism 2, and a third conveying mechanism 3. The first conveying mechanism 1 is horizontally arranged on the surface of the wharf, the third conveying mechanism 3 is horizontally arranged on the water surface below the wharf, and the second conveying mechanism 2 is vertically arranged, with its upper and lower ends connected to the first conveying mechanism 1 and the third conveying mechanism 3, respectively.

[0023] In contrast to the shortcomings of existing technologies, this invention addresses the challenge of stone throwing in complex spaces. The stones are transported via a first conveyor mechanism 1 located on the wharf surface, and then further transported by a second conveyor mechanism 2 and a third conveyor mechanism 3. This continuous and precise transmission and throwing of stones from the wharf surface to a designated location on the water surface solves the problem of stone throwing in complex spaces. Furthermore, the collaborative operation of the first, second, and third conveyor mechanisms 1 and 2 allows the stone throwing operation to traverse the narrow spaces formed by the upper sheltered structure of the wharf, enabling stone throwing operations in areas difficult to access by traditional methods, such as the gaps between pile foundations at the wharf's front edge and behind sheltered areas. Secondly, the mechanized three-stage conveyor mechanism operates continuously, replacing traditional manual or intermittent mechanical operations to improve construction efficiency. Moreover, operators do not need to enter dangerous construction areas, reducing safety risks such as falling rocks, drowning during water operations, and mechanical collisions. Therefore, this invention boasts advantages such as strong spatial adaptability, high stone throwing accuracy, high construction efficiency, and good safety performance.

[0024] In some embodiments, the first conveying mechanism 1, the second conveying mechanism 2, and the third conveying mechanism 3 are all telescopic structures. Specifically, through the above-described configuration, the first conveying mechanism 1, the second conveying mechanism 2, and the third conveying mechanism 3 can all adjust their telescopic length to suit the construction of coastal high-pile wharves of different scales and structures, thus meeting diverse construction needs.

[0025] In some embodiments, the first conveying mechanism 1 includes a first telescopic frame 5, with casters 6 at its bottom. A first drive mechanism 8 and a first conveyor belt 9 are mounted on the first telescopic frame 5. The first drive mechanism 8 drives the first conveyor belt 9. An inverted trapezoidal funnel 10 is positioned above the first conveyor belt 9 at the front end of the first telescopic frame 5. The inverted trapezoidal funnel 10 has an inlet 11 at its upper end and an outlet 12 at its rear end. The casters 6 can be omnidirectional casters. Specifically, during installation, the first conveying mechanism 1 is hoisted to a predetermined position on the dock surface using hoisting equipment. The casters 6 are adjusted to ensure good contact between the first conveying mechanism 1 and the dock surface, allowing for flexible movement. The inverted trapezoidal funnel 10 is then installed. Finally, the steel pipe structures on both sides of the end of the first telescopic frame 5 are tightly connected to the upper sides of the second conveying mechanism 2 using bolts.

[0026] It should be noted that the height of the discharge port 12 is 40cm to ensure the height of the stone accumulation and to ensure that the stone can be transferred to the L-shaped partition 18 of the second conveyor 2 for transportation when it is transported to the second conveyor 2. In addition, the installation of the moving wheels 6 allows the first conveyor 1 to move its position according to the site conditions or adjust its height by using the terrain.

[0027] The first drive mechanism 8 may include a first drive motor connected to a reducer, the output end of which is connected to a roller to drive the first conveyor belt 9. The first telescopic frame 5 may include a first fixed frame 51 and a first movable frame 52. The first movable frame 52 is slidably fitted on a first linear guide rail located on the first fixed frame 51 and can be pushed by a first electric push rod, allowing it to extend and retract relative to the first fixed frame 51. The first conveyor belt 9 is mounted on the first fixed frame 51 and the first movable frame 52, and its length can be adjusted when the first movable frame 52 extends and retracts. Furthermore, the first movable frame 52 may also be equipped with a tensioning mechanism for adjusting the tension of the first conveyor belt 9. After adjusting the length of the first conveyor belt 9, the tension can be adjusted via the tensioning mechanism. Specifically, the tensioning mechanism includes a fixed roller and a tensioning wheel that both abut against the first conveyor belt 9. The tensioning wheel is driven by power to move away from the fixed roller, giving the first conveyor belt 9 a suitable tension.

[0028] In some embodiments, the second conveying mechanism 2 includes a first mounting frame 13, on which a second drive mechanism 15, a second conveyor belt 16, and a second telescopic frame 17 are mounted. The second drive mechanism 15 drives the second conveyor belt 16. The second conveyor belt 16 has multiple L-shaped partitions 18 along its transport direction. Two baffles 19 are located on either side of the multiple L-shaped partitions 18. A pulley group 20 is located at the bottom of the second telescopic frame 17, and the pulley group 20 engages with the third conveying mechanism 3. The distance between two adjacent L-shaped partitions 18 is 1m, and the L-shaped partition 18 has a lateral dimension of 0.4m and a longitudinal dimension of 0.3m. Specifically, the second drive mechanism 15 drives the second conveyor belt 16, allowing the multiple L-shaped partitions 18 on the second conveyor belt 16 to move cyclically around its transport direction, transporting stones from the first conveying mechanism 1 to the lower third conveying mechanism 3 via the L-shaped partitions 18.

[0029] It should be noted that the position of the pulley block 20 can be adjusted by adjusting the telescopic length of the second telescopic frame 17, thereby enabling adaptive adjustment according to the tidal conditions of the operating sea area and the pressure between the pulley block 20 and the third transmission mechanism 3. The specific structure of the second telescopic frame 17 may include a second movable frame, which is slidably fitted on a second linear guide rail located on the first mounting frame 13, and can be pushed by a second electric push rod to achieve the above-mentioned adjustment.

[0030] In some embodiments, the third conveying mechanism 3 has grooves 21 on both sides, and the pulley group 20 is disposed in the grooves 21. A detector 24 is mounted on the pulley group 20. Specifically, the pulley group 20 includes multiple pulleys disposed on both sides of the bottom of the second telescopic frame 17, preferably two pulleys on each side. Furthermore, the pulleys are connected to the grooves 21, and a certain force is applied to ensure good contact. A limit buckle is provided 1m behind the grooves 21 to ensure that the pulley group 20 does not derail. In addition, the detector 24 located on the pulley group 20 can adjust the lifting and lowering of the pulley group 20 according to the tidal conditions of the operating sea area and the pressure between the pulley group 20 and the third conveying mechanism 3.

[0031] The detector 24 may include a pressure-type tide sensor and an array-type piezoelectric sensor to measure the hydrostatic pressure of seawater and calculate the water depth by measuring the hydrostatic pressure of seawater by the pressure-type tide sensor, and to test the pressure between the pulley group 20 and the third transmission mechanism 3 by embedding the array-type piezoelectric sensor in the contact surface between the pulley group 20 and the third transmission mechanism 3.

[0032] In some embodiments, the third conveying mechanism 3 includes a third telescopic frame 22, on which a third drive mechanism 23 and a third conveyor belt 25 are mounted. The third drive mechanism 23 can drive the third conveyor belt 25 for transmission. Multiple powered propellers 26 are mounted on the third telescopic frame 22. A sonar 27, a camera 28, and a lighting lamp 29 are also mounted on the third telescopic frame 22, with the sonar 27 located at the bottom of the third telescopic frame 22. Slides 21 are located on both sides of the third telescopic frame 22. Specifically, during installation, the third conveyor mechanism 3 is hoisted to the water surface below the dock using hoisting equipment, allowing its bottom pontoon to float stably on the water. The pulley block 20 is then connected to the chute 21. Secondly, the position of the stone-throwing mechanism can be adjusted by changing the telescopic length of the third telescopic frame 22, or by adjusting the position of the third conveyor mechanism 3 using the propeller 26, ensuring omnidirectional stone-throwing by the conveyor belt. Furthermore, sonar 27, camera 28, and lighting 29 are installed and tested to ensure normal equipment operation and accurate data transmission. The sonar 27, located at the bottom of the third telescopic frame 22, can detect underwater depth and the height above the concealed structure, used to determine the stone-throwing situation and whether the tidal influence will cause contact with the concealed structure above, ensuring equipment safety.

[0033] It should be noted that there are multiple propellers 26. A total of four propellers 26 are set on both sides and the rear of the third telescopic frame 22. The propellers 26 on both sides are used for left and right turning, and the propellers 26 at the rear are used for forward and backward movement. The specific structure and telescopic principle of the third telescopic frame 22 can be referred to the first telescopic frame 5 mentioned above, and will not be repeated here.

[0034] In some embodiments, lateral stops 30 are provided on both sides of the first telescopic frame 5 and the third telescopic frame 22. Specifically, the lateral stops 30 are provided to prevent stones from falling from both sides of the first telescopic frame 5 and the third telescopic frame 22.

[0035] In some embodiments, the coastal high-pile wharf rock-throwing device further includes a control module, with the first conveying mechanism 1, the second conveying mechanism 2, and the third conveying mechanism 3 all connected to the control module. Detector 24, sonar 27, camera 28, and lighting 29 are also connected to the control module, which has a built-in wireless receiving module for receiving signals. Specifically, the operator sends a command signal to the control module via a remote control, and the control module coordinates the three conveying mechanisms to perform coordinated actions, achieving continuous and precise transmission and throwing of rocks from the wharf surface to a designated position on the water surface.

[0036] The stone-throwing process of this invention is as follows: Material loading operation: Use an excavator or crawler crane to load stones that meet the specifications into the inverted trapezoidal hopper 10 located on the first conveyor belt 9, control the feeding speed to avoid too much or too little stone accumulation, and ensure that the conveyor belt transmits stones stably and evenly.

[0037] Stone transport: The first conveyor belt 9 smoothly transports the stones to the second conveyor belt 16. With the help of the L-shaped baffles 18 on the second conveyor belt 16, the stones remain orderly arranged and are transported downwards, ensuring that they do not fall during the transition from horizontal to vertical transport. The second conveyor mechanism 2 can extend and retract according to the water surface conditions, adjusting the position of the pulley block 20 to maintain a suitable distance between the bottom of the second conveyor belt 16 and the third conveyor belt 25. This ensures that the stones land accurately on the third conveyor belt 25, preventing secondary rolling or severe wear on the belt due to excessive distance. Simultaneously, the third conveyor belt 25 transports the stones to the throwing point, completing the entire throwing process. Lateral baffles 30 are installed on both sides of the third conveyor belt 25 to prevent stone leakage.

[0038] omnidirectional stone throwing: The third conveyor belt 25 adjusts its length via a telescopic function according to the preset rock-throwing position. Simultaneously, the propeller 26 drives the third conveyor belt 25 to swing, transporting rocks to the designated location for throwing. Operators monitor the rock-throwing process in real time using data detected by sonar 27 and images captured by camera 28. They adjust the position, angle, and telescopic length of the third conveyor belt 25 as needed to ensure accurate and uniform rock-throwing, meeting the requirements of the revetment construction. During the rock-throwing process, the conveyor belt's operating status is continuously monitored, and any abnormalities are immediately addressed by stopping the machine.

[0039] The beneficial effects of this invention are as follows: 1. Strong spatial adaptability: Through the cooperation of the three-stage conveyor mechanism, it can traverse the narrow space formed by the upper shelter structure of the wharf, enabling rock-throwing operations in areas that are difficult to reach by traditional methods, such as the gaps between pile foundations at the wharf's front edge and the area behind the shelter. The movement and extension functions of the first conveyor mechanism 1 allow it to operate flexibly on wharves with different frame and surface layer lengths; the vertical extension of the second conveyor mechanism 2 adapts to tidal changes; and the swinging and extension functions of the third conveyor mechanism 3 enable all-round, blind-angle rock-throwing, greatly expanding the construction range. 2. High Rock Throwing Accuracy: Sonar 27 detects underwater topography and pile foundation positions in real time, while camera 28 and lighting 29 provide clear operational images, allowing operators to accurately monitor the rock throwing area. The precise design and stable operation of the three-stage conveying mechanism, along with the L-shaped baffle 18, baffle 19, and lateral stop blocks 30, ensure orderly and stable rock transport. The extension and swing control of the third conveying mechanism 3 minimizes the error in rock landing point, significantly improving rock throwing accuracy compared to existing technologies and effectively enhancing the quality of bank protection projects. 3. High construction efficiency: The mechanized three-stage conveyor system operates continuously, replacing traditional manual or intermittent mechanical operations. After an excavator or crawler crane feeds stones into the hopper, the stones are automatically and quickly transported and thrown via the conveyor belt, reducing manual intervention and equipment adjustment time. The conveyor belt's movement, extension, and oscillation functions can quickly adapt to different construction locations and working conditions, enabling rapid site transfers and continuous construction, significantly improving construction efficiency, increasing single-shift workload, effectively shortening the construction cycle, and reducing project costs. 4. Excellent Safety Performance: Most operations are completed remotely, eliminating the need for operators to enter hazardous construction areas and reducing safety risks such as falling rocks, drowning during water operations, and mechanical collisions. The baffles 19 on both sides of the conveyor belt, the side blocks 30, and the L-shaped partitions 18 effectively prevent stone leakage and falling, ensuring the safety of construction personnel and equipment. The equipment's stability and reliability design, along with the application of a debugging and monitoring system, further enhances the safety of the construction process and reduces the probability of accidents. 5. Excellent Applicability and Economy: The rock-throwing device is suitable for the construction of coastal high-pile wharves of different scales and structures. By adjusting the parameters of the conveyor belt and the installation method, it can meet diverse construction needs. Its efficient and precise construction characteristics reduce material waste and subsequent maintenance costs; the mechanized and automated operation mode reduces labor costs and equipment wear and tear, demonstrating good economic efficiency and application value, and bringing significant economic and social benefits to the wharf construction industry.

[0040] In addition, the present invention also provides a method for installing a rock-throwing device at a coastal high-pile wharf, which includes the following steps: Step S1: The first conveying mechanism 1 is hoisted to the predetermined position on the surface of the wharf using hoisting equipment, and an inverted trapezoidal funnel 10 is installed at the front end of the first conveying mechanism 1; wherein, the position and extension length of the first conveying mechanism 1 can be adjusted according to the site conditions. Step S2: The second conveying mechanism 2 is vertically installed at the front edge of the dock using hoisting equipment and connected to the first conveying mechanism 1; wherein, the second conveying mechanism 2 can adjust the telescopic conveying length according to the water surface conditions; Step S3: The third conveyor 3 is hoisted to the water surface below the dock using hoisting equipment, so that the third conveyor 3 floats steadily on the water surface, and the third conveyor 3 is connected to the second conveyor 2; wherein, the position, angle and extension length of the third conveyor 3 can be adjusted according to the position of the stone being thrown.
