Description

Technical Field

[0001] This utility model relates to the field of ship lifting equipment technology, specifically a marine hydraulic monorail crane. Background Technology

[0002] Marine monorail cranes, as a type of lifting equipment widely used in the shipbuilding industry, play a crucial role in the entire ship cargo lifting operation. They are mainly composed of two core parts: rails and lifting devices. The rails are generally made of high-strength steel and are usually installed on the top or side walls of the ship's cabins. The design and installation of these rails must be strictly based on the ship's structural characteristics and actual usage requirements to ensure that they can stably and reliably bear the weight of the lifting devices and cargo.

[0003] The monorail gantry plays a crucial role in the cargo handling process of ships, playing an irreplaceable role in a series of operations such as loading and unloading cargo and transferring cargo between different areas of the ship. Whether it is loading and unloading cargo when the ship is in port or transferring cargo between different compartments during the ship's voyage, the marine monorail gantry is an indispensable and important piece of equipment.

[0004] Traditional marine electric monorail cranes typically use electric motors as the power source to achieve the lifting and moving functions of cargo. The working system of these devices is usually S2 (intermittent duty), which means that they can only work for short periods of time and cannot operate continuously for long periods of time. Even if an S1 (continuous duty) motor is used, it cannot meet the requirements for long-term uninterrupted work. Therefore, there are limitations in practical applications. To address this, a marine hydraulic monorail crane is proposed. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a marine hydraulic monorail crane, which can effectively solve the problems in the prior art.

[0006] The technical solution adopted by this utility model is as follows: a marine hydraulic monorail crane, including a movable crossbeam, a track beam above the movable crossbeam, an oil tank fixedly connected to the upper end of the movable crossbeam, a pump station motor fixedly connected to the lower end of the movable crossbeam, one end of a coupling fixedly connected to the output end of the pump station motor, a hydraulic pump fixedly connected to the other end of the coupling, a manual multi-way reversing valve and an electrical control box fixedly connected to the front end of the movable crossbeam, the electrical control box being electrically connected to a wired remote controller via a line, a hydraulic lifting device fixedly connected to the upper end of the movable crossbeam, hooks provided at both ends of the movable crossbeam, a hydraulic walking mechanism fixedly connected to the center of the upper end of the movable crossbeam, a support mechanism fixedly connected to the upper end of the movable crossbeam, and a maintenance platform fixedly connected to the lower end of the movable crossbeam;

[0007] The fuel tank includes an outer shell, a baffle plate, and a connection hole. The baffle plate is fixedly connected inside the outer shell, and the connection hole is provided on the side of the baffle plate.

[0008] The hydraulic walking mechanism includes a frame, a hydraulic motor, a drive wheel, and a balance wheel. The hydraulic motor is fixedly connected to the rear end of the frame, the drive wheel is fixedly connected to the output end of the hydraulic motor, and the balance wheel is rotatably connected to the inner side of the frame.

[0009] Preferably, the wave deflector is parallel to the two side walls of the outer shell.

[0010] The above technical solution incorporates a wave deflector and connecting holes. The wave deflector effectively suppresses the sloshing of oil in all directions within the tank. Because of its parallel arrangement, the oil is more evenly blocked and buffered when sloshing, further enhancing the stability of the monorail crane during travel and ship swaying. This reduces problems such as changes in the center of gravity caused by oil sloshing, ensuring the safe and stable operation of the monorail crane. The connecting holes ensure the fluidity of the oil within the tank.

[0011] Preferably, the oil tank and the hydraulic pump are connected to each other through pipelines, and the hydraulic pump is a plunger pump.

[0012] Through the above technical solution, the hydraulic pump adopts a plunger pump, which has the advantages of high pressure, high efficiency and convenient flow adjustment. The pump station motor drives the coupling, thereby driving the hydraulic pump to run. The hydraulic pump can efficiently provide sufficient power to the entire hydraulic system, meet the power needs of the monorail crane in the process of lifting and moving goods, and ensure the smooth operation of the work.

[0013] Preferably, two identical hydraulic lifting devices are provided, and the two hydraulic lifting devices are symmetrically distributed at both ends of the hydraulic walking mechanism.

[0014] Through the above technical solution, the two symmetrically distributed hydraulic lifting devices can ensure that the cargo is subjected to uniform force during the lifting process, making the monorail crane more stable when lifting cargo on the left and right sides, preventing the cargo from tilting or falling due to uneven force, improving the safety and reliability of the lifting operation, and also helping to maintain the balance of the overall structure of the monorail crane.

[0015] Preferably, the hydraulic lifting device is equipped with a hydraulic motor.

[0016] Through the above technical solution, the hydraulic motor can convert hydraulic energy into mechanical energy, providing stable power for the hydraulic lifting device.

[0017] Preferably, the wired remote controller is electrically connected to the pump station motor, the manual multi-way reversing valve, the electrical control box, the hydraulic lifting device, and the hydraulic walking mechanism.

[0018] Through the above technical solutions, operators can conveniently remotely control the start and stop of the pump station motor using a wired remote control, or operate the hydraulic lifting device and hydraulic walking mechanism by controlling the hydraulic oil flow using a manual multi-way directional valve. Furthermore, the electrical control box can achieve coordinated control of multiple functions, greatly improving the convenience and flexibility of operation. This allows operators to fully control the monorail crane from a safe distance, ensuring the safety of operators and the accuracy of operation.

[0019] Preferably, the oil tank is embedded in the top of the movable crossbeam, and the hydraulic pump is located directly below the oil tank.

[0020] The above technical solution embeds the oil tank into the top of the moving crossbeam, reducing the space occupied by the entire monorail crane. At the same time, it allows the hydraulic pump to directly obtain hydraulic oil from the oil tank, reducing the pipeline length.

[0021] Compared with the prior art, this utility model provides a marine hydraulic monorail crane, which has the following advantages:

[0022] 1. The marine hydraulic monorail crane has a wave deflector in the oil tank that is parallel to the two sides of the outer shell. The wave deflector has connection holes. When the monorail crane is moving or affected by the swaying of the ship, it can effectively suppress the swaying of the oil in the oil tank, reduce the adverse effect of the oil swaying on the stability of the monorail crane, ensure the stable operation of the monorail crane under complex working conditions, and reduce the safety risks caused by swaying.

[0023] 2. This marine hydraulic monorail crane features a hydraulic travel mechanism located at the center of the upper end of the moving crossbeam. A hydraulic motor drives the drive wheels, enabling the monorail crane to move smoothly on the track beam. A balance wheel further maintains balance during movement, ensuring stable travel and facilitating accurate cargo lifting. Two symmetrically distributed hydraulic lifting devices are located at both ends of the hydraulic travel mechanism. Each device contains a hydraulic motor, ensuring even force distribution on the cargo during lifting. This allows for stable lifting of cargo on both port and starboard sides, preventing tilting or falling due to uneven force, thus improving the safety and reliability of lifting operations. The use of a fully hydraulic drive system replaces the traditional electric drive, overcoming the limitations of traditional marine electric monorail cranes that rely on electric motors for short-term operation. This allows for continuous long-term operation, meeting the needs of continuous cargo lifting during ship operations and improving operational efficiency.

[0024] 3. The ship uses a hydraulic monorail crane. Operators can centrally control the monorail crane operation through the manual multi-way directional valve on the maintenance platform, or remotely operate it using a wired remote control that is electrically connected to the pump station motor, manual multi-way directional valve, electrical control box, hydraulic lifting device and hydraulic walking mechanism.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0032] Example 1: As Figure 1-5 As shown, the present invention provides a marine hydraulic monorail crane, including a movable crossbeam 1, a track beam 2 above the movable crossbeam 1, an oil tank 3 fixedly connected to the upper end of the movable crossbeam 1, a pump station motor 4 fixedly connected to the lower end of the movable crossbeam 1, one end of a coupling 5 fixedly connected to the output end of the pump station motor 4, a hydraulic pump 6 fixedly connected to the other end of the coupling 5, a manual multi-way reversing valve 7 and an electrical control box 8 fixedly connected to the front end of the movable crossbeam 1, the electrical control box 8 being electrically connected to a wired remote controller 9 via a line, a hydraulic lifting device 10 fixedly connected to the upper end of the movable crossbeam 1, hooks 11 at both ends of the movable crossbeam 1, a hydraulic walking mechanism 12 fixedly connected to the center of the upper end of the movable crossbeam 1, a support mechanism 13 fixedly connected to the upper end of the movable crossbeam 1, and a maintenance platform 14 fixedly connected to the lower end of the movable crossbeam 1.

[0033] The fuel tank 3 includes an outer shell 301, a baffle plate 302 and a connection hole 303. The baffle plate 302 is fixedly connected inside the outer shell 301, and the connection hole 303 is opened on the side of the baffle plate 302.

[0034] The hydraulic walking mechanism 12 includes a frame 1201, a hydraulic motor 1202, a drive wheel 1203, and a balance wheel 1204. The hydraulic motor 1202 is fixedly connected to the rear end of the frame 1201, the drive wheel 1203 is fixedly connected to the output end of the hydraulic motor 1202, and the balance wheel 1204 is rotatably connected to the inner side of the frame 1201.

[0035] Specifically, the wave deflector 302 is parallel to the two side walls of the outer shell 301. The advantage is that the wave deflector 302 and the connecting hole 303 allow the wave deflector 302 to more effectively suppress the sloshing of oil in all directions within the oil tank 3. Because of the parallel arrangement, the oil is more evenly blocked and buffered when sloshing, further enhancing the stability of the monorail crane during travel and ship swaying, reducing problems such as changes in the center of gravity caused by oil sloshing, and ensuring the safe and stable operation of the monorail crane. The connecting hole 303 ensures the fluidity of the oil within the oil tank 3.

[0036] Specifically, the oil tank 3 and the hydraulic pump 6 are interconnected via pipelines, and the hydraulic pump 6 is a plunger pump. The advantages of using a plunger pump are high pressure, high efficiency, and convenient flow adjustment. The pump station motor 4 drives the coupling 5, thereby driving the hydraulic pump 6. The hydraulic pump 6 can efficiently provide sufficient power to the entire hydraulic system, meeting the power requirements of the monorail crane during lifting and moving goods, and ensuring smooth operation.

[0037] Example 2: Figure 2-5 As shown, this is an improvement on the previous embodiment.

[0038] Specifically, two identical hydraulic lifting devices 10 are provided, symmetrically distributed at both ends of the hydraulic traveling mechanism 12. The advantage is that the two symmetrically distributed hydraulic lifting devices 10 ensure even force distribution on the cargo during lifting, making the monorail crane more stable when lifting cargo on the port and starboard sides. This prevents the cargo from tilting or falling due to uneven force distribution, improving the safety and reliability of the lifting operation, and also helps maintain the overall balance of the monorail crane structure.

[0039] Specifically, the hydraulic lifting device 10 is equipped with a hydraulic motor 1202. The advantage is that the hydraulic motor 1202 can convert hydraulic energy into mechanical energy, providing stable power to the hydraulic lifting device 10.

[0040] Specifically, the wired remote controller 9 is electrically connected to the pump station motor 4, the manual multi-way directional valve 7, the electrical control box 8, the hydraulic lifting device 10, and the hydraulic walking mechanism 12. The advantage is that operators can conveniently remotely control the start and stop of the pump station motor 4 via the wired remote controller 9, or use the manual multi-way directional valve 7 to control the hydraulic oil flow to operate the hydraulic lifting device 10 and the hydraulic walking mechanism 12. Furthermore, the electrical control box 8 enables coordinated control of multiple functions, greatly improving operational convenience and flexibility. This allows operators to fully control the monorail from a safe distance, ensuring operator safety and operational precision.

[0041] Specifically, the oil tank 3 is embedded in the top of the moving crossbeam 1, and the hydraulic pump 6 is located directly below the oil tank 3. The advantage is that embedding the oil tank 3 in the top of the moving crossbeam 1 reduces the space occupied by the entire monorail crane, and also allows the hydraulic pump 6 to directly obtain hydraulic oil from the oil tank 3, reducing pipeline length.

[0042] Working principle: When in use, the motor 4 of the hydraulic pump station is started. The motor 4 drives the hydraulic pump 6 to start running through the coupling 5. The oil tank 3 provides hydraulic oil to the hydraulic pump 6. The anti-sloshing plate 302 in the oil tank 3 can reduce oil sloshing during the movement of the monorail and ensure a stable supply of hydraulic oil. The hydraulic pump 6 pressurizes the hydraulic oil and delivers it to the entire hydraulic system to provide power for subsequent operations. The operator can control the hydraulic walking mechanism 12 through the manual multi-way reversing valve 7 on the maintenance platform 14 or the wired remote control 9. When a movement command is issued, the electrical control box 8 receives the signal and controls the hydraulic oil to flow to the hydraulic motor 1202 in the hydraulic walking mechanism 12. The hydraulic motor 1202 starts to rotate, driving the drive wheel 1203 to rotate, causing the moving beam 1 of the monorail to move horizontally on the track beam 2. The balance wheel 1204 rotates inside the frame 1201 to help maintain the balance of the monorail during the movement, ensuring that the monorail moves smoothly to the target position. When the monorail reaches the designated position, the two hydraulic lifting devices 10 are started to work. The hydraulic motor 1202 inside each hydraulic lifting device 10 operates under the drive of hydraulic oil, and the goods are lifted through the hook 11.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
