Description
Technical Field
[0001] The utility model relates to the field of ship supporting facilities, in particular to a ship lifting and rescue device. Background Art
[0002] Lifting equipment is a type of special equipment. Marine lifting refers to the installation of cranes on ships, which can be used for rescue, loading and unloading, crew ship repairs, etc. It is mainly used for salvage at sea, lifting ships, cargo and personnel to rescue people and objects.
[0003] Traditional marine lifting and rescue equipment mainly uses steel cables and hooks to lift people and objects. Although the steel cables are equipped with anti-corrosion structures to avoid the invasion of seawater and salt spray, the steel cables are movable parts. After a long time, they will inevitably wear out and cause damage to the protective layer, which makes the steel cables easily eroded by salt spray carried by the sea breeze or stirred up sea waves. Although this phenomenon can be avoided through regular maintenance, the maintenance requires manual application of the protective layer and it needs to be done every once in a while, which is time-consuming, labor-intensive and cumbersome. Utility Model Content
[0004] Based on this, the purpose of the utility model is to provide a marine lifting and rescue equipment to solve the technical problems mentioned in the above background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a marine lifting and rescue equipment, comprising an electric turntable and a counterweight block, a protective component is arranged on the top of the counterweight block, and the protective component comprises a box body, a guide plate is connected to one side of the inside of the box body, and a scraper sleeve is connected to one side of the guide plate, and a guide wheel is connected to the top of the guide plate.
[0006] By adopting the above technical scheme, lubricating grease is poured into the box so that the wound steel cable is immersed in the lubricating grease, which isolates the steel cable from contact with air and seawater, thereby extending the service life of the steel cable, and during maintenance, it is only necessary to apply a protective layer to the area of the steel cable that has been exposed to the outside, thereby reducing the complexity of maintenance. When the steel cable is released, the steel cable brings out the lubricating grease. At this time, the excess lubricating grease is scraped off by the scraper sleeve, so that only a layer of oil film remains on the surface of the steel cable. First, it avoids excessive lubricating grease on the surface of the steel cable, which causes excessive dripping of lubricating grease when the steel cable is outside and causes waste. Second, it has a certain coating effect, so that the lubricating grease on the surface of the steel cable is evenly distributed to avoid exposure. When the steel cable is wound, if impurities adhere to the surface of the lubricating grease, the diameter of the steel cable will be increased, so that these impurities will contact the scraper sleeve. Therefore, after the steel cable is retracted, some impurities adhering to the surface of the lubricating grease can be removed by the scraper sleeve, and then these impurities are guided away by the guide plate to avoid entering the box, thereby extending the service life of the lubricating grease.
[0007] Furthermore, the guide plate is arranged at an angle.

[0012] By adopting the above technical solution, the retractable reel is connected to the output end of the motor before the equipment is operated, the boom can be rotated horizontally through the electric turntable, and the boom can be rotated vertically through the hydraulic cylinder. At the same time, the length of the equipment can be extended or shortened by setting the extension arm. When the motor drives the retractable reel to rotate and release the steel cable, the hook moves down due to the influence of gravity, so that the staff can hang people or objects on the hook. When the motor drives the retractable reel to reverse and retract the steel cable, the hook moves up due to the tension, thereby lifting people or objects.
[0013] Furthermore, the upper arm is rotatably connected to the base, and the extension arm is slidably connected to the upper arm.
[0014] By adopting the above technical solution, the boom can be rotated vertically through the hydraulic cylinder, and the length of the equipment can be extended or shortened by setting the extension arm.
[0015] Furthermore, the cylinder body of the hydraulic cylinder is rotatably connected to the base, and the piston rod of the hydraulic cylinder is rotatably connected to the boom.
[0016] By adopting the above technical solution, when the motor drives the reel to rotate and release the steel cable, the hook moves downward under the influence of gravity, so that the staff can hang people or objects on the hook, and the hydraulic cylinder can make the boom rotate vertically.
[0017] Furthermore, the steel cable is in contact with the guide wheel, and the diameter of the steel cable is smaller than the diameter of the scraper sleeve.
[0018] By adopting the above technical solution, the steel cable brings out the lubricating grease, and at this time, the excess lubricating grease is scraped off by the scraper sleeve, so that only a layer of oil film remains on the surface of the steel cable. Firstly, it avoids excessive lubricating grease on the surface of the steel cable, which causes excessive dripping of lubricating grease when the steel cable is outside and causes waste. Secondly, it has a certain smearing effect, so that the lubricating grease on the surface of the steel cable is evenly distributed to avoid exposure.
[0019] Furthermore, a heater is installed at the lower part of the box body, and heat conducting rods are connected to both sides of the top of the heater, and a paddle is connected to one side of the retractable roll.
[0020] By adopting the above technical solution, when the temperature is low, heat is generated by the heater and transferred by the heat conducting rod, so as to heat the lubricating grease to prevent the lubricating grease from solidifying due to too low temperature. Then, the reel is rotated to reel in or release the wire rope, thereby driving the paddle to rotate, thereby stirring the lubricating grease to make it evenly distributed.
[0021] Furthermore, a plurality of heat conducting rods are provided, and the plurality of heat conducting rods are symmetrically distributed.
[0022] By adopting the above technical solution, heat is generated by the heater and transferred by the heat conducting rod, so that the lubricating grease is heated to prevent the lubricating grease from solidifying due to excessively low temperature.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0033] The following describes an embodiment of the utility model based on its overall structure. Embodiment 1:
[0034] A marine lifting and rescue equipment, such as Figure 1-Figure 3 As shown, it includes an electric turntable 1 and a counterweight block 3, and a protective component 9 is arranged on the top of the counterweight block 3.
[0035] Specifically, the protection component 9 includes a box body 901 connected to the top of the counterweight block 3, and a guide plate 903 is connected to one side of the inside of the box body 901. The guide plate 903 is arranged at an angle, and the impurities scraped off by the scraper sleeve 904 are guided away by the guide plate 903 to prevent them from entering the box body 901; a scraper sleeve 904 is connected to one side of the guide plate 903, and the diameter of the steel cable 8 is smaller than the diameter of the scraper sleeve 904. When the steel cable 8 is released, the excess lubricating grease is scraped off by the scraper sleeve 904, so that only a layer of oil film remains on the surface of the steel cable 8. After the steel cable 8 is retracted, the scraper sleeve 904 can remove some impurities adhering to the surface of the lubricating grease; two guide wheels 902 are connected to the top of the guide plate 903, and the two guide wheels 902 are symmetrically distributed. The steel cable 8 is in contact with the guide wheels 902, which is convenient for guiding the steel cable 8.
[0036] See also Figure 1 and Figure 2In the above embodiment, the top of the electric turntable 1 is connected to the base 2, so that the boom 4 can rotate horizontally; the top of the base 2 is connected to the boom 4, the boom 4 is rotatably connected to the base 2, a hydraulic cylinder 7 is installed between the boom 4 and the base 2, the cylinder body of the hydraulic cylinder 7 is rotatably connected to the base 2, and the piston rod of the hydraulic cylinder 7 is rotatably connected to the boom 4, so that the boom 4 can rotate vertically; an extension arm 5 is connected to one side of the boom 4, and the extension arm 5 is slidably connected to the boom 4, which can extend or shorten the length of the equipment; a counterweight block 3 is connected to one side of the top of the base 2 to balance the weight of both ends of the equipment; a reel 10 is connected to the inside of the box 901, a steel cable 8 is connected to the top of the reel 10, and a hook 6 is connected to the bottom of the steel cable 8 to facilitate lifting people or objects. Embodiment 2:
[0037] On the basis of the above-mentioned embodiment 1, although the maintenance complexity can be reduced by setting the protective component 9, the lubricating grease is easy to solidify in cold weather, affecting the rotation of the reel 10. Now, by setting the heater 11, the heat conduction plate 12 and the dial plate 13, the lubricating grease can be heated to avoid the lubricating grease solidifying due to the low temperature.
[0038] See also Figure 2 and Figure 4 In the above embodiment, a heater 11 is installed at the lower part of the box body 901, and multiple heat-conducting rods 12 are connected to both sides of the top of the heater 11. The multiple heat-conducting rods 12 are symmetrically distributed. Heat is generated by the heater 11 and heat is transferred by the heat-conducting rods 12, so that the lubricating grease is heated; a paddle 13 is connected to one side of the reel 10, and multiple paddles 13 are provided. The multiple paddles 13 are distributed in a ring array. When the reel 10 rotates to reel in or unwind the steel cable 8, the paddle 13 is driven to rotate, so that the lubricating grease is stirred and evenly distributed.
[0039] The implementation principle of the utility model is as follows: first, the staff fills the box 901 with lubricating grease so that the rolled steel cable 8 is immersed in the lubricating grease, isolating the steel cable 8 from contact with air and seawater, thereby extending the service life of the steel cable 8, and during maintenance, only the protective layer needs to be applied to the area of the steel cable 8 that has been exposed to the outside. When there are many impurities in the lubricating grease or it is exhausted, the staff can scoop out the lubricating grease in the box 901 and pour in new lubricating grease. Compared with regularly applying a protective layer to the entire cable, the maintenance complexity is reduced;
[0040] Before the equipment is operated, the reel 10 is connected to the output end of the motor. The motorized turntable 1 allows the boom 4 to rotate horizontally, and the hydraulic cylinder 7 allows the boom 4 to rotate vertically. At the same time, the extension arm 5 can be set to extend or shorten the length of the equipment. When the motor drives the reel 10 to rotate and release the steel cable 8, the hook 6 moves downward under the influence of gravity, so that the staff can hang people or objects on the hook 6. When the motor drives the reel 10 to reverse and retract the steel cable 8, the hook 6 moves upward under the influence of tension, so as to lift people or objects.
[0041] When the steel cable 8 is released, the steel cable 8 brings out the lubricating grease. At this time, the excess lubricating grease is scraped off by the scraper sleeve 904, so that only a layer of oil film remains on the surface of the steel cable 8. Firstly, it avoids excessive lubricating grease on the surface of the steel cable 8, which causes excessive dripping of lubricating grease when the steel cable 8 is outside and causes waste. Secondly, it has a certain coating effect, so that the lubricating grease on the surface of the steel cable 8 is evenly distributed to avoid exposure. When the steel cable 8 is reeled in, if impurities adhere to the surface of the lubricating grease, the diameter of the steel cable 8 will be increased, so that these impurities will contact the scraper sleeve 904. Therefore, after the steel cable 8 is retracted, the scraper sleeve 904 can remove some impurities adhering to the surface of the lubricating grease, and then these impurities are guided away by the guide plate 903 to avoid entering the box 901, thereby extending the service life of the lubricating grease.
[0042] When the temperature is low, heat is generated by the heater 11 and transferred by the heat conducting rod 12, thereby heating the lubricating grease to prevent the lubricating grease from solidifying due to the low temperature. Then, the reel 10 is rotated to reel in or unwind the steel cable 8, driving the paddle 13 to rotate, thereby stirring the lubricating grease to make it evenly distributed.
[0043] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
