Description

Technical Field

[0001] The utility model belongs to the technical field of inland waterway maintenance, and in particular relates to a 25-meter-class navigation boat used in inland rivers. Background Art

[0002] Currently, many inland waterway maintenance operations rely on 25-meter-class navigation aid boats. However, these boats are not very mechanized, and many tasks still require intensive manual labor, placing a heavy workload on navigation aid boat operators. Transporting navigation aid equipment from the pontoon warehouse to the navigation aid boats requires manual and shoulder lifting, which is time-consuming and labor-intensive. The handling process also poses significant safety risks, impacting the overall efficiency of waterway maintenance operations.

[0003] Specifically, the mechanization level of existing 25-meter-class navigation aid boats is relatively low. Only a small number of these boats are equipped with electric winches for anchoring and deploying buoys, but most operations, such as equipment handling and anchor stone placement, still rely on manual labor. Currently, during the navigation aid installation process for channel maintenance operations, the handling of anchor stones and anchor chains relies on manual labor, and the removal of debris from buoys also requires multiple people to perform manually. This is not only inefficient but also poses a high safety risk. Due to limited space in ship warehouses, the transportation of navigation aid equipment required for channel maintenance is cumbersome and dangerous, increasing operational difficulty and safety hazards.

[0004] The Yangtze River Navigation Administration's 30-meter-class buoy vessel, designated "Hangdao 04118," is scheduled for completion and delivery in 2023. It is equipped with a hydraulic crane with a multifunctional manipulator, a cable-tightening winch, and an anchor-turning platform. However, these components are purchased separately, resulting in a lack of integration. This not only occupies a significant amount of space on the vessel but also incurs high installation costs. A 25-meter-class buoy boat, however, lacks the space and energy required to simultaneously install these components due to its smaller hull and smaller generator set. This results in a still-low level of operational efficiency for these boats.

[0005] Therefore, it is necessary to design a new 25-meter-class buoy boat for inland rivers. Summary of the Invention

[0006] The purpose of the utility model is to provide a 25-meter-class navigation boat for inland rivers, so as to solve the problems of high labor intensity, many safety hazards and low efficiency in inland waterway maintenance operations proposed in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides a 25-meter-class navigation beacon boat for inland rivers, comprising a bottom cabin, a cabin and a front deck; a hydraulic crane, a hydraulic winch and a hydraulic turning platform are arranged on the front deck, the hydraulic crane is arranged in the middle of the front deck, the hydraulic winch is arranged in front of the hydraulic crane, and the hydraulic turning platform is arranged on one side of the front deck; the hydraulic crane, the hydraulic winch and the hydraulic turning platform share a set of hydraulic pump stations; a comprehensive operating platform for controlling the hydraulic crane, the hydraulic winch and the hydraulic turning platform is also provided on the front deck; the navigation beacon boat is also provided with a multi-way reversing valve, and the hydraulic pump station is connected to the hydraulic crane, the hydraulic winch and the hydraulic turning platform respectively through the multi-way reversing valve; the comprehensive operating platform is respectively connected to the hydraulic pump station, the multi-way reversing valve, the hydraulic crane, the hydraulic winch and the hydraulic turning platform; the hydraulic pump station is arranged in the bow tank of the bottom cabin; the rated lifting weight of the hydraulic crane is 500kg, the maximum working radius of the hydraulic crane is 5.2 meters, and the minimum working radius is 2 meters.

[0008] In a specific embodiment, the hydraulic crane is a telescopic hydraulic crane, including a crane base, a slewing tower, a slewing bearing, a first boom, a boom cylinder, a second boom, a third boom, a fourth boom, a first telescopic cylinder, a second telescopic cylinder, a third telescopic cylinder, and a hydraulic rope winch.

[0009] In a specific embodiment, the hydraulic winch is a hydraulic winch with a rated pulling force of 20KN.

[0010] In a specific embodiment, the hydraulic tilting platform is a hydraulic tilting platform with a rated lifting weight of 1 ton.

[0011] In a specific embodiment, the bottom cabin includes a forepeak cabin, a rigging cabin, a void cabin, an engine room and a sternpeak cabin arranged from front to back.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The utility model improves the mechanization degree of waterway maintenance operations, can reduce manual operations and improve work efficiency compared to existing 25-meter-class navigation beacon boats.

[0014] The present invention reduces the physical labor of traditional operations such as manual handling, cleaning, and laying anchor stones by installing a hydraulic crane, a hydraulic winch, and a hydraulic turnover platform on a 25-meter-class buoy boat, thereby reducing the labor intensity of waterway maintenance. The rated power of the generator set equipped on a 25-meter-class buoy boat is only 16kW. The hydraulic pump stations corresponding to the purchased hydraulic crane, hydraulic winch, and hydraulic turnover platform each require at least 7.5kW, totaling at least 22.5kW of total power generation. The 25-meter-class buoy boat will not be able to achieve power supply, and at least a 30-meter-class buoy boat will be required to meet the power supply requirements. The present invention, by installing a multi-way reversing valve, allows a set of hydraulic pump stations to stagger their use time to provide hydraulic power to the hydraulic crane, hydraulic winch, and hydraulic turnover platform respectively, thereby allowing the hydraulic crane, hydraulic winch, and hydraulic turnover platform to be installed on the 25-meter-class buoy boat at the same time, and realizing the power supply of the hydraulic crane, hydraulic winch, and hydraulic turnover platform. At the same time, by combining the hydraulic pump stations originally corresponding to the hydraulic crane, hydraulic winch, and hydraulic tilting platform into one, the installation space occupied is reduced. The shared hydraulic pump station also reduces the weight added to the entire ship due to the installation of the hydraulic crane, hydraulic winch, and hydraulic tilting platform, while also saving the purchase cost of the hydraulic pump station.

[0015] This new system integrates the hydraulic control systems of the hydraulic crane, hydraulic winch, and hydraulic turnover platform into a comprehensive operating platform, which not only makes the operation integrated and modular, but also significantly reduces the overall system weight by sharing the hydraulic pump station. It also solves the problem of power supply for ship generator sets and the problem of equipment installation in ship deck cabins.

[0016] The utility model solves the potential safety hazards of manual operation and reduces the safety risks of operators when operating on a 25-meter-class navigation beacon boat through mechanized operation.

[0017] The utility model improves the quality of maintenance work, especially the accuracy and efficiency of operations such as navigation mark laying and anchor stone placement, by using modern mechanical equipment and automated tools.

[0018] In addition to the above-described purposes, features and advantages, the present invention has other purposes, features and advantages. The present invention will be further described in detail below with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention can be implemented in many different ways as defined and covered by the claims.

[0028] Example 1

[0029] like Figure 1 As shown, the utility model provides a 25-meter-class navigation boat for inland rivers, including a bottom cabin, a cabin and a front deck; a hydraulic crane 1, a hydraulic winch 3 and a hydraulic flip platform 2 are provided on the front deck, as shown in FIG. Figure 2 As shown, the hydraulic crane 1 is arranged in the middle of the front deck, the hydraulic winch 3 is arranged in front of the hydraulic crane 1, and the hydraulic flip platform 2 is arranged on one side of the front deck; the hydraulic crane 1, the hydraulic winch 3 and the hydraulic flip platform 2 share a set of hydraulic pump stations.

[0030] A 25-meter-class buoy boat has a beam of 5.2 meters and a foredeck length of 6.5 meters. When the hydraulic crane 1's boom is extended to 5.2 meters, it can extend 2.6 meters beyond the side.

[0031] Hydraulic crane 1 is centrally located at the 41st rib on the foredeck. This placement minimizes obstruction to the bridge's view, ensuring that the vessel's stability calculations meet regulatory requirements. With a 5.2-meter boom, hydraulic crane 1 is capable of lifting a 25-meter-class buoy boat from the port, starboard, and bow.

[0032] The foredeck is also equipped with an integrated operating platform for controlling the hydraulic crane 1, hydraulic winch 3, and hydraulic turnover platform 2. The 25-meter-class beacon boat is also equipped with a multi-way reversing valve 5, through which the hydraulic pump station is connected to the hydraulic crane 1, hydraulic winch 3, and hydraulic turnover platform 2 respectively; the integrated operating platform 4 is connected to the hydraulic pump station, multi-way reversing valve 5, hydraulic crane 1, hydraulic winch 3, and hydraulic turnover platform 2 respectively; Figure 3 This is a schematic diagram of a hydraulic pump station shared by a hydraulic crane 1, a hydraulic winch 3, and a hydraulic turnover platform 2.

[0033] The control systems for the hydraulic crane 1, hydraulic winch 3, and hydraulic tilting platform 2 are integrated into a single integrated operating platform 4, sharing a common hydraulic pump station. This significantly reduces the overall system weight and makes the hydraulic system's operation integrated and modular. This upgrades the 25-meter-class navigation aid boat from a channel patrol vessel to a channel maintenance vessel with mechanized operation capabilities.

[0034] The integrated operating platform 4 drives the motor of the hydraulic pump station, which drives the hydraulic pump to pump compressed hydraulic oil into the multi-way reversing valve. The integrated operating platform operates the multi-way reversing valve, which drives the hydraulic oil to the telescopic, slewing, and luffing cylinders, thereby controlling the hydraulic crane. The multi-way reversing valve drives the hydraulic winch, controlling its forward and reverse rotation. The multi-way reversing valve also drives the hydraulic tilting platform, controlling its raising and lowering.

[0035] like Figure 5 and Figure 6 As shown, the hydraulic crane 1 is a telescopic hydraulic crane, comprising a crane base, a slewing tower, a slewing bearing, a first boom, a luffing cylinder, a second boom, a third boom, a fourth boom, a first telescopic cylinder, a second telescopic cylinder, a third telescopic cylinder, and a hydraulic winch. The hydraulic crane has a rated lifting capacity of 500 kg, a maximum operating radius of 5.2 meters, and a minimum operating radius of 2 meters. The hydraulic crane has a lifting speed of 0-12 m / min, a slewing speed of 0-1.2 r / min, a luffing time of 70 seconds, and a system pressure of 21 MPa. The hydraulic crane weighs 600 kg without the hydraulic pump station. The hydraulic pump station has a power of 7.5 kW, a speed of 1470 r / min, and a power supply of 380 V / 50 Hz. The hydraulic crane base has a diameter of 0.9 meters, a height of 1.96 meters, and a retracted boom width of 2.04 meters.

[0036] The hydraulic winch 3 is a hydraulic winch with a rated pulling force of 20KN. The working speed of the hydraulic winch is greater than 20 rice / min. The hydraulic winch is centrally located on the foredeck at rib 45, providing ample space for operation and maintenance. During navigation aid deployment and maintenance, as well as buoy placement and retrieval, the hydraulic winch pulls the wire rope or anchor chain to quickly and precisely position and secure the buoy.

[0037] The hydraulic tilting platform 2 is a hydraulic tilting platform with a rated lifting weight of 1 ton. Figure 4 The hydraulic flip platform is located on the starboard side of the bow at the 40th rib. Using the platform to deploy anchor stones effectively reduces operational complexity, allowing for timely and accurate timing of deployment, effectively ensuring accurate positioning of the navigation mark. Furthermore, operators operate from a safe area behind the deck, ensuring personal safety.

[0038] The bottom cabin comprises a forepeak cabin, a rigging cabin, a void cabin, an engine room and a stern peak cabin arranged from front to back. The hydraulic pump station is arranged in the forepeak cabin of the bottom cabin.

[0039] In waterway maintenance work, the utility model enables waterway maintenance operations such as lifting anchors and chains, setting and removing buoys, and clearing objects wrapped around buoy anchor chains to be completed mechanically. This improves the quality and efficiency of maintenance work. By using hydraulic cranes and hydraulic winches, it can effectively save time on the transportation of navigation equipment, the laying of navigation marks, and the lifting and dropping of anchors, greatly improving the efficiency of maintenance work. The utility model also solves the problem of navigation marks moving due to rising water during the flood season. By using a mechanized hydraulic crane to upgrade the navigation mark to a 300KG anchor stone, it will become simple and efficient. Increasing the anchor stone setting can effectively solve the problem of large-scale displacement of navigation marks during the flood season.

[0040] The present invention reduces the physical labor of traditional operations such as manual handling, cleaning, and anchor stone laying by arranging a hydraulic crane, a hydraulic winch, and a hydraulic turning platform on a 25-meter-class buoy boat, thereby reducing the labor intensity of waterway maintenance. The rated power of the generator set equipped on a 25-meter-class buoy boat is only 16kW. The hydraulic pump stations corresponding to the purchased hydraulic crane, hydraulic winch, and hydraulic turning platform each require at least 7.5kW, totaling at least 22.5kW of total power generation. The 25-meter-class buoy boat will not be able to achieve power supply, and at least a 30-meter-class buoy boat will be required to meet the power supply requirements. The present invention, by arranging a multi-way reversing valve, allows a set of hydraulic pump stations to stagger their use time to provide hydraulic power to the hydraulic crane, hydraulic winch, and hydraulic turning platform respectively, thereby allowing the hydraulic crane, hydraulic winch, and hydraulic turning platform to be installed on the 25-meter-class buoy boat at the same time, and realizing the power supply of the hydraulic crane, hydraulic winch, and hydraulic turning platform. At the same time, by combining the hydraulic pump stations originally corresponding to the hydraulic crane, hydraulic winch, and hydraulic tilting platform into one, the installation space occupied is reduced. The shared hydraulic pump station also reduces the weight added to the entire ship due to the installation of the hydraulic crane, hydraulic winch, and hydraulic tilting platform, while also saving the purchase cost of the hydraulic pump station.

[0041] While a traditional 25-meter-class buoy boat takes 25 minutes to complete a single buoy setting operation, the new system only takes 15 minutes, improving efficiency by 40%. The anchor stone positioning error of a traditional 25-meter-class buoy boat is within 3 meters, while the new system only achieves an error of 1.5 meters, improving positioning accuracy by 50%. This improved efficiency has reduced the average energy consumption per buoy setting operation from 16.125 kg of diesel to 11.825 kg.

[0042] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, several simple deductions and substitutions can be made without departing from the concept of the present invention, and all of these should be considered to fall within the scope of protection of the present invention.
