Description
Technical Field
[0001] This application relates to the field of maritime rescue equipment technology, and in particular to a lifting device for a rescue vessel. Background Technology
[0002] Marine lifting equipment on rescue vessels enables the transfer of cargo from ships to docks or vice versa, efficiently handling various types of cargo, including containers, bulk cargo, and liquid cargo, ensuring rapid and safe loading and unloading at ports. Simultaneously, marine lifting equipment can be used for maritime operations such as salvage, equipment repair, and personnel transfer in emergency rescue situations at sea.
[0003] Existing marine lifting equipment is often large in size and not convenient to combine components flexibly according to the size and needs of the rescue vessel. This results in inconvenience and low flexibility in use, as well as problems such as high cost, large space occupation, heavy weight and complicated operation. Utility Model Content
[0004] The purpose of this invention is to solve or at least alleviate the problem in the prior art that it is not convenient to flexibly combine components according to the size and needs of the rescue vessel.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a lifting device for a rescue vessel, comprising a climbing pole mounted on the rescue vessel, a support frame mounted at the bottom of the climbing pole, and a base plate mounted on the rescue vessel. Multiple limiting sleeves for installing lifting ropes are symmetrically fixed on the climbing pole. Multiple connecting discs are provided on the climbing pole, each of the connecting discs has a detachable latch, and each of the latches has a pulley assembly for guiding the lifting ropes. A material release mechanism for raising and lowering the lifting ropes is provided on the base plate.
[0006] The feeding mechanism includes two fixed plates symmetrically fixedly installed on the base plate. The same feeding roller is rotatably installed on the two fixed plates. Two limiting discs for limiting the lifting rope are symmetrically fixedly installed on the feeding roller. A first fixed frame is fixedly installed on one side of one of the fixed plates. A first motor is fixedly installed on the first fixed frame. The output end of the first motor is fixedly connected to the feeding roller through a coupling.
[0007] By adopting the above technical solution, the first motor is started by controlling its output, which drives the feeding roller to rotate. The rotating feeding roller feeds the lifting rope, and the lifting rope can lift and lower the object at one end of the rope while feeding the material, thus completing the lifting operation. Therefore, this application uses components that are easy to install, disassemble, and replace. The components can be flexibly combined according to the size and needs of the rescue vessel. The foldable lifting arm reduces space occupation when not in use and improves the space utilization of the vessel. Furthermore, this application can change the size, diameter, pulley block, and other accessories of the climbing pole according to different types of rescue vessels and the lifting capacity of the main hook. It has the advantages of low cost and simple operation, while improving efficiency and being applicable to a variety of rescue scenarios.
[0008] Optionally, two three-dimensional plates are symmetrically fixedly installed on the top of the base plate. A first pressing roller and a second pressing roller are rotatably installed on the side of the two three-dimensional plates that are close to each other. Two meshing first gears and second gears are rotatably installed on one side of one of the three-dimensional plates. One end of the first gear and the second gear are fixedly connected to the corresponding first pressing roller and the second pressing roller, respectively.
[0009] By adopting the above technical solution, two upright plates can be set up to assist in the installation.
[0010] Optionally, a housing is fixedly installed on one side of one of the three-dimensional plates, and the side of the housing closest to the three-dimensional plate is open, enclosing the first gear and the second gear.
[0011] By adopting the above technical solution, the installation can be aided by setting up a box.
[0012] Optionally, a second mounting bracket is fixedly installed on one side of the housing, and a second motor is fixedly installed on the second mounting bracket. The output end of the second motor is fixedly connected to a second gear through a coupling.
[0013] By adopting the above technical solution, the second motor is started and its output end drives the second gear to rotate. The rotation of the second gear drives the first gear to rotate as well. The rotation of the first and second gears drives the corresponding first and second pressing rollers to rotate as well. This can squeeze the surface of the lifting rope, thereby squeezing out most of the water in the lifting rope and preventing the lifting rope from containing too much water, which would increase the weight of winding and cause corrosion, thus reducing the strength of the rope.
[0014] Optionally, two adjusting rods are symmetrically fixedly installed on the top of the base plate, and the telescopic ends of the two adjusting rods are fixedly installed with the same lifting frame, and a guide roller is rotatably installed inside the lifting frame.
[0015] By adopting the above technical solution, the lifting rope can be guided and moved by setting guide rollers.
[0016] Optionally, both adjusting rods are composed of a sleeve and a rod, and are fitted together. Each of the two adjusting rods has a threaded hole on one outer surface, and an adjusting bolt is screwed into each of the two threaded holes.
[0017] By adopting the above technical solution, by stretching two adjusting rods, the lifting frame and guide rollers will move upward. The position of the adjusting rods can be positioned and installed by adjusting bolts, so the height can be adjusted according to the needs, which facilitates the guidance of multiple lifting ropes, thereby improving the convenience and flexibility of use.
[0018] Optionally, a mounting plate is fixedly installed at the bottom of the climbing pole, and both the mounting plate and the support frame are fixedly installed on the rescue boat by external bolts.
[0019] By adopting the above technical solution, the installation disk can be set up to assist in the installation process.
[0020] Optionally, a guide plate is fixedly installed on one side of the base plate, and the guide plate is inclined.
[0021] By adopting the above technical solution, water can be guided and discharged by setting a guide plate, thereby facilitating rapid drainage.
[0022] In summary, the beneficial effects of this application are as follows:
[0023] 1. This application utilizes a climbing pole and other components to lift and lower the object at one end of the lifting rope while releasing the material, thus completing the lifting operation. The application employs components that are easy to install, disassemble, and replace, allowing for flexible combination of components according to the size and needs of the rescue vessel. It also features a foldable lifting arm, reducing space occupation when not in use and improving the vessel's space utilization. Furthermore, the application allows for the replacement of climbing pole dimensions, pipe diameters, pulley systems, and other accessories based on the type of rescue vessel and the main hook's lifting capacity. This results in low cost, ease of operation, increased efficiency, and applicability to various rescue scenarios.
[0024] 2. In this application, the new invention employs a first pressing roller and the like. By controlling the start of a second motor, the output of the second motor drives the second gear to rotate. The rotation of the second gear drives the first gear to rotate as well. The rotation of the first and second gears drives the corresponding first and second pressing rollers to rotate as well. This allows the surface of the lifting rope to be squeezed, thereby squeezing out most of the water in the lifting rope and preventing the lifting rope from containing too much water, which would increase the weight of winding and cause corrosion, thus reducing the rope's strength.

The buckles 6 and pulley assemblies 7 in this application are all prior art, so the specific structure and usage process are not described in detail. The base plate 8 is provided with a feeding mechanism, a drainage mechanism, and a guiding mechanism for raising and lowering the lifting rope. By setting up the drainage mechanism, it is possible to avoid the lifting rope containing too much water, which would increase the weight of winding and cause corrosion, leading to a decrease in the strength of the rope and affecting its service life.
[0032] The feeding mechanism includes two fixed plates 10 symmetrically fixed on the base plate 8, a feeding roller 11 rotatably mounted on the two fixed plates 10, two limiting discs 12 symmetrically fixed on the feeding roller 11 for limiting the lifting rope, and a first fixed frame 13 fixedly mounted on one side of one of the fixed plates 10, a first motor 14 fixedly mounted on the first fixed frame 13, and the output end of the first motor 14 fixedly connected to the feeding roller 11 through a coupling.
[0033] In use, by controlling the start of the first motor 14, the output of the first motor 14 will drive the feeding roller 11 to rotate. The feeding roller 11 rotates and feeds the lifting rope. While feeding the material, the lifting rope can lift and lower the item at one end of the lifting rope to complete the lifting operation. Therefore, this application adopts components that are easy to install, disassemble and replace, and can flexibly combine components according to the size and needs of the rescue boat. It adopts a foldable lifting arm to reduce space occupation when not in use and improve the space utilization of the ship. Moreover, this application can change the size, pipe diameter, pulley group and other accessories of the climbing pole 1 according to different types of rescue boats and the lifting capacity of the main hook. It has the advantages of low cost and simple operation, while improving efficiency and being suitable for a variety of rescue scenarios.
[0034] Reference Figure 2-3The drainage mechanism includes two three-dimensional plates 15 symmetrically fixedly installed on the top of the base plate 8, with a first pressing roller 18 and a second pressing roller 19 rotatably installed on the side of the two three-dimensional plates 15 that are close to each other. Two meshing first gears 20 and second gears 21 are rotatably installed on one side of one of the three-dimensional plates 15. One end of the first gear 20 and the second gear 21 are fixedly connected to the corresponding first pressing roller 18 and the second pressing roller 19, respectively. A box 16 is fixedly installed on one side of one of the three-dimensional plates 15, and the side of the box 16 close to the three-dimensional plate 15 is open, enclosing the first gear 20 and the second gear 21. A second fixing frame 22 is fixedly installed on one side of the box 16. A second motor 23 is fixedly installed on the second fixing frame 22, and the output end of the second motor 23 is fixedly connected to the second gear 21 through a coupling.
[0035] In use, by controlling the start of the second motor 23, the output end of the second motor 23 will drive the second gear 21 to rotate. The rotation of the second gear 21 will drive the first gear 20 to rotate as well. The rotation of the first gear 20 and the second gear 21 will drive the corresponding first pressing roller 18 and the second pressing roller 19 to rotate as well. This can squeeze the surface of the lifting rope, thereby squeezing out most of the water in the lifting rope and preventing the lifting rope from containing too much water, which would increase the weight of winding and cause corrosion, thus reducing the strength of the rope.
[0036] In this application, the first motor 14 and the second motor 23 are started simultaneously during both feeding and receiving, thereby avoiding motion interference.
[0037] Reference Figure 3-4 The guiding mechanism includes two adjusting rods 17 symmetrically fixedly installed on the top of the base plate 8, and the telescopic ends of the two adjusting rods 17 are fixedly installed with the same lifting frame 24. A guide roller 25 is rotatably installed in the lifting frame 24. The two adjusting rods 17 are composed of sleeves and sleeve rods and are fitted together. Two threaded holes 26 are opened on the outer surface of one side of the two adjusting rods 17. Two adjusting bolts 27 are screwed into the two threaded holes 26. An installation plate 2 is fixedly installed at the bottom of the climbing pole 1. The installation plate 2 and the support frame 4 are fixedly installed on the rescue boat by external bolts. A guide plate 9 is fixedly installed on one side of the base plate 8. The guide plate 9 is inclined.
[0038] In use, by stretching the two adjusting rods 17, the lifting frame 24 and guide roller 25 will move upward. The position of the adjusting rods 17 can be positioned by adjusting the bolts 27, so that the height can be adjusted according to the needs, which facilitates the guidance of multiple lifting ropes, thus improving the convenience and flexibility of use. By setting the guide plate 9, water can be guided and discharged, which facilitates rapid drainage.
[0039] The implementation principle of this application is as follows: When in use, the first motor 14 is started by controlling the start of the first motor 14, and the output end of the first motor 14 will drive the feeding roller 11 to rotate. The feeding roller 11 rotates and feeds the lifting rope. While the lifting rope is feeding the material, it can lift and lower the item at one end of the lifting rope and complete the lifting operation. Therefore, this application adopts components that are easy to install, disassemble and replace. The components can be flexibly combined according to the size and needs of the rescue boat. The foldable lifting arm is used to reduce space occupation when not in use and improve the space utilization of the ship. Moreover, this application can change the size, pipe diameter, pulley group and other accessories of the climbing pole 1 according to different types of rescue boats and the lifting capacity of the main hook. It has the advantages of low cost and simple operation, while improving efficiency and being suitable for a variety of rescue scenarios.
[0040] By controlling the start of the second motor 23, the output of the second motor 23 will drive the second gear 21 to rotate. The rotation of the second gear 21 will drive the first gear 20 to rotate as well. The rotation of the first gear 20 and the second gear 21 will drive the corresponding first pressing roller 18 and the second pressing roller 19 to rotate as well. This will squeeze the surface of the lifting rope, thereby squeezing out most of the water in the lifting rope and preventing the lifting rope from containing too much water, which would increase the weight of winding and cause corrosion, thus reducing the strength of the rope.
[0041] By stretching the two adjusting rods 17, the lifting frame 24 and guide roller 25 will move upward. The position of the adjusting rods 17 can be positioned and installed by adjusting the bolts 27, so that the height can be adjusted according to the needs, which facilitates the guidance of multiple lifting ropes, thereby improving the convenience and flexibility of use.
