Technical Field
[0001] This utility model belongs to the field of marine equipment technology, and specifically relates to a marine lifeboat launching and lowering device with remote oil delivery lubrication. Background Technology
[0002] A lifeboat is a small, sturdy, and maneuverable vessel that is typically mounted on ships, offshore platforms, and other water facilities. It is used to evacuate people from dangerous areas in emergencies (such as shipwrecks or sinkings) and ensure their safety. When ships are sailing at sea, lifeboats are key escape equipment, and the design of their storage and release mechanisms is of paramount importance.
[0003] Chinese Patent No. CN204264416U discloses a free-fall type lifeboat launching device, including a support base, an inclined slide corresponding to the lifeboat on the support base, a release hook at the upper end of the slide, and the slide having a door frame structure.
[0004] During long-term use, the lubrication requirements of the various connection points of the lifeboat launching device have become increasingly prominent. Due to the complex structure of the launching device, the locations of various nodes are scattered, and some connection points are located in hard-to-reach and concealed positions. Manually adding lubricating oil poses a great challenge. Operators need to spend a lot of time and energy to locate, approach and lubricate each connection point, which undoubtedly increases the difficulty and intensity of maintenance work. Especially in emergency situations, such as when the lifeboat needs to be launched and lowered quickly, if jamming or malfunction occurs due to long-term lack of lubrication, manual lubrication obviously cannot meet the needs of rapid response and may delay the rescue opportunity. Therefore, there is an urgent need for a remote oil delivery lubrication solution for the launching device. Utility Model Content
[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a marine lifeboat launching and lowering device with remote oil delivery lubrication.
[0006] The above-mentioned technical objective of this utility model can be achieved through the following technical solution: a marine lifeboat launching and lowering device with remote oil supply lubrication, including a support base, an inclined slide corresponding to the lifeboat provided on the support base, a boom rotatably connected to the support base, a winch provided at the lower end of the boom, a hydraulic cylinder rotatably mounted on the support base, the output end of the hydraulic cylinder rotatably connected to the middle part of the boom, a hanging cable movably mounted on the boom, the hanging cable connected to the winch, a crossbeam device for suspending the lifeboat connected to the end of the hanging cable, a plurality of rollers rotatably mounted on the boom, the hanging cable sequentially passing over the plurality of rollers, two guide wheels rotatably mounted on the boom, and an oil supply assembly provided on the boom, the oil supply assembly being used to supply lubricating oil to the connection points of the plurality of rollers and the connection points of the two guide wheels.
[0007] In the above-mentioned marine lifeboat launching device with remote oil supply lubrication, the oil supply component includes several oil supply pipes. The inlet ends of the several oil supply pipes are all connected to the output end of the pump body in the external oil storage unit. The outlet ends of several oil supply pipes are respectively aligned with and close to the connection point of the corresponding roller, and the outlet ends of the remaining oil supply pipes are respectively aligned with and close to the connection point of the corresponding guide wheel.
[0008] In the aforementioned marine lifeboat launching device with remote oil delivery lubrication, several of the oil delivery pipelines are equipped with flow control valves and flow sensors. The flow sensors are used to monitor the flow rate in the oil delivery pipeline in real time and transmit the data to an external controller. The flow control valves are used to adjust the flow rate at the outlet end of the oil delivery pipelines and are electrically connected to the external controller.
[0009] In the aforementioned marine lifeboat launching device with remote oil delivery lubrication, pressure sensors and pressure relief valves are installed in several of the oil delivery pipelines. The pressure sensors are used to monitor the pressure in the oil delivery pipelines in real time and transmit the data to an external controller. When the real-time pressure value reaches the preset pressure value on the external controller, the external controller controls the pressure relief valve to open. When the real-time pressure value is lower than the preset pressure value on the external controller, the external controller controls the pressure relief valve to close.
[0010] In the aforementioned marine lifeboat launching device with remote oil delivery lubrication, the pressure relief valve is connected to an external oil storage unit via a return oil pipeline.
[0011] In the above-mentioned marine lifeboat launching device with remote oil delivery lubrication, the inner diameter of the outlet end of several oil delivery pipes decreases continuously along their axial direction, and the inner diameter of the outlet end of several oil delivery pipes is the smallest.
[0012] In the aforementioned marine lifeboat launching device with remote oil delivery lubrication, several oil delivery pipelines are formed by connecting several individual pipelines through joints.
[0013] In the aforementioned marine lifeboat launching device with remote oil delivery lubrication, several of the individual pipes are made of plastic alloy material, and the outer surface of several of the individual pipes is coated with an anti-corrosion coating.
[0014] In summary, the beneficial effects of this utility model compared to the prior art are as follows:
[0015] An oil delivery assembly is installed on the boom to deliver lubricating oil to the connection points of several rollers and two guide wheels. This ensures that the rollers and guide wheels are adequately lubricated, resulting in smoother rotation, reduced friction, extended service life, and a lower risk of wear-related failures. This effectively improves the overall structural reliability. Furthermore, compared to manual lubrication, lubrication via the oil delivery assembly significantly improves lubrication efficiency, reduces the workload of maintenance personnel, and makes maintenance work more efficient.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0021] Marine lifeboat launching devices with remote oil delivery lubrication, such as Figures 1 to 3 As shown, the system includes a support base 1, on which an inclined slide 2 corresponding to the lifeboat is provided. A boom 3 is rotatably connected to the support base 1, and a winch 4 is provided at the lower end of the boom 3. A hydraulic cylinder 5 is rotatably mounted on the support base 1, and the output end of the hydraulic cylinder 5 is rotatably connected to the middle part of the boom 3. A hanging cable 6 is movably mounted on the boom 3 and is connected to the winch 4. The end of the hanging cable 6 is connected to a crossbeam device 7 for suspending the lifeboat. Several rollers 8 are rotatably mounted on the boom 3, and the hanging cable 6 passes around several rollers 8 in sequence. Two guide wheels 9 are rotatably mounted on the boom 3.
[0022] The boom 3 is equipped with an oil delivery assembly, which is used to deliver lubricating oil to the connection points of several rollers 8 and the connection points of two guide wheels 9. Specifically, the oil delivery assembly includes several oil delivery pipes 10. The inlet ends of the oil delivery pipes 10 are all connected to the output end of the pump body in the external oil storage unit. The outlet ends of several oil delivery pipes 10 are aligned with and close to the connection points of the corresponding rollers 8, and the outlet ends of the remaining oil delivery pipes 10 are aligned with and close to the connection points of the corresponding guide wheels 9.
[0023] It should be noted that in the current technology, the connection points of the roller 8 and the guide wheel 9 are usually lubricated by manually adding lubricating oil. However, in this embodiment, lubricating oil is delivered through several oil supply pipes 10, so that the lubricating oil can directly and effectively act on the positions that need lubrication, which greatly improves the efficiency of lubrication operation, reduces the workload of maintenance personnel, and makes maintenance work more efficient.
[0024] Furthermore, the inner diameter of the outlet end of several oil pipelines 10 continuously decreases along their axial direction, and the inner diameter of the outlet end of several oil pipelines 10 is the smallest. This increases the flow rate of lubricating oil, and the lubricating oil can act more concentratedly on the location that needs lubrication when it flows out, improving the accuracy of lubrication and avoiding waste of lubricating oil and unnecessary environmental pollution.
[0025] Preferably, each of the several oil pipelines 10 is formed by connecting several individual pipelines 15 through joints 16, which facilitates the later maintenance of the oil pipelines 10. When any individual pipeline 15 is damaged, it can be disassembled and replaced individually without replacing the entire oil pipeline 10, making the maintenance work simpler and the maintenance cost lower.
[0026] In this embodiment, several individual pipes 15 are made of plastic alloy material, and the outer surface of several individual pipes 15 is coated with an anti-corrosion coating. The individual pipes 15 made of plastic alloy material are lightweight, which is conducive to installation and maintenance, and have good corrosion resistance. They can effectively resist the erosion of individual pipes 15 by factors such as salt spray and humidity in marine environments, and the anti-corrosion coating on their outer surface can further resist erosion.
[0027] Each of the several oil pipelines 10 is equipped with a flow control valve 11 and a flow sensor 12. The flow sensor 12 is used to monitor the flow rate in the oil pipeline 10 in real time and transmit the data to an external controller. The flow control valve 11 is used to adjust the flow rate at the outlet end of the oil pipeline 10. Both the flow control valve 11 and the flow sensor 12 are electrically connected to the external controller. On-site personnel can operate the flow control valve 11 through the external controller to adjust the flow rate at the outlet end of the oil pipeline 10. That is, by adjusting the opening of the flow control valve 11, the flow rate at the outlet end of the oil pipeline 10 is changed. Therefore, users only need to operate the flow control valve 11 on the external controller to adjust the flow rate at the outlet end of the oil pipeline 10, thereby changing the output of lubricating oil in each oil pipeline 10 to meet the lubrication needs of different locations.
[0028] It should be noted that the flow control valve 11 and the flow sensor 12 can be ordinary flow control valves 11 and flow sensors 12 in the existing technology, so their specific structure and working principle will not be described in detail.
[0029] Pressure sensors 13 and pressure relief valves 14 are installed in several oil pipelines 10. Both pressure sensors 13 and pressure relief valves 14 are electrically connected to an external controller. Pressure sensors 13 are used to monitor the pressure in the oil pipeline 10 in real time and transmit the data to the external controller. When the real-time pressure value reaches the preset pressure value on the external controller, the external controller controls the pressure relief valve 14 to open. When the real-time pressure value is lower than the preset pressure value on the external controller, the external controller controls the pressure relief valve 14 to close. That is, under complex sea conditions, the stability of the oil transmission pressure is controlled and safety is improved by real-time pressure monitoring and pressure relief valve 14.
[0030] The pressure relief valve 14 is connected to an external oil storage unit via a return oil pipe (not shown) to collect the lubricating oil discharged during pressure relief back into the external oil storage unit, thus avoiding waste.
[0031] It should be noted that the pressure relief valve 14 and pressure sensor 13 can be ordinary pressure relief valves 14 and pressure sensors 13 in the existing technology, so their specific structure and working principle will not be described in detail.
[0032] The specific embodiments described herein are merely illustrative examples of the spirit of this utility model; those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or adopt similar methods to replace them, but without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
