Description

Technical Field

[0001] This utility model relates to the technical field of marine lifting equipment, specifically a marine lifting equipment for synchronous rope cleaning. Background Technology

[0002] Marine cranes are specialized cranes used in maritime environments for transport operations. They are primarily used for important tasks such as cargo transfer between ships, replenishment at sea, and deployment and retrieval of underwater equipment. Due to the unique geographical environment at sea, they constantly face the swaying of the ship caused by waves, and the hook needs to be retracted promptly after each use.

[0003] Because seawater is corrosive, the surface of ropes will be corroded after being exposed to seawater. In the existing technology, rope cleaning is usually done manually, which not only increases the labor intensity of workers, but also poses certain dangers for high-altitude operations. Therefore, we have introduced a marine hoisting system that can clean ropes simultaneously. Utility Model Content

[0004] The purpose of this invention is to provide a marine hoisting device for synchronous rope cleaning, which can clean the rope simultaneously as it is raised. This not only provides a good cleaning effect on the rope, but also makes the rope less susceptible to seawater corrosion, thus increasing the rope's service life. Furthermore, it reduces the labor intensity of workers and improves safety, thereby solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A marine lifting device for synchronous rope cleaning includes a boom, with rollers rotatably mounted at the end of the boom via a pivot, a rope mounted on the rollers, and a cylinder surrounding the rope. Connecting rods are rotatably mounted on both sides of the boom at the rollers via rolling bearings, with the lower ends of the connecting rods fixedly connected to the upper ends of the cylinder. A rotating ring is rotatably mounted inside the cylinder via rolling bearings, with brushes fixedly mounted on the inner wall of the rotating ring. The brushes are positioned to abut against the rope, and a transmission mechanism is provided between the rotating ring and the cylinder.

[0007] Furthermore, the transmission mechanism includes a motor, which is fixedly mounted on the outer wall of the cylinder. The output end of the motor extends into the cylinder and is fixedly provided with a gear. The upper end of the rotating ring is provided with gear teeth, which mesh with the gear.

[0008] Furthermore, a liquid storage tank is fixedly provided on the outer wall of the cylinder, and an annular tube is provided on the outside of the rope below the rotating ring. Multiple spray holes are evenly provided on the inner side of the annular tube, and a liquid outlet pipe is fixedly provided at the bottom of the liquid storage tank. One end of the liquid outlet pipe passes through the cylinder and is fixedly connected to the annular tube.

[0009] Furthermore, an atomizing nozzle is installed at the spray hole.

[0010] Furthermore, the storage tank contains seawater cleaning solution.

[0011] Furthermore, the liquid storage tank is provided with a liquid inlet at the top.

[0012] Furthermore, the brush is an acid and alkali resistant brush.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This marine lifting equipment for simultaneous rope cleaning utilizes a system consisting of ropes, rollers, a liquid inlet, a storage tank, a cylinder, connecting rods, a motor, a boom, brushes, gears, a rotating ring, a liquid outlet pipe, a ring pipe, and atomizing nozzles. As the winch on the crane begins winding the rope, the rope rises, activating the motor and water pump, and opening valves. After the valve on the liquid outlet pipe opens, seawater cleaning solution from the storage tank enters the outlet pipe. The water pump pressurizes the solution and atomizes it through multiple nozzles on the ring pipe, spraying it evenly onto the rope. The motor drives the gears, which in turn drive the rotating ring to rotate. Simultaneously, the rotating ring drives the brushes to scrub the circumference of the rope. This allows for simultaneous cleaning as the rope rises, resulting in effective cleaning, reduced seawater corrosion, longer rope lifespan, decreased worker workload, and improved safety.

[0020] 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.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution:

[0022] A marine lifting device for synchronous rope cleaning includes a boom 8. A roller 2 is rotatably mounted at the end of the boom 8 via a pivot. A rope 1 is mounted on the roller 2. One end of the rope 1 is connected to an electric winch on the lifting device, and the other end is fixedly connected to a hook. A cylinder 5 is provided outside the rope 1. Connecting rods 6 are rotatably mounted on both sides of the boom 8 at the roller 2 via rolling bearings. The lower end of the connecting rods 6 is fixedly connected to the upper end of the cylinder 5. A rotating ring 11 is rotatably mounted inside the cylinder 5 via rolling bearings. A brush 9 is fixedly mounted on the inner wall of the rotating ring 11, and the brush 9 is positioned against the rope 1. The brush 9 is an acid and alkali resistant brush, which is not easily corroded by seawater and has a long service life.

[0023] A transmission mechanism is provided between the rotating ring 11 and the cylinder 5. The transmission mechanism includes a motor 7. The motor 7 is electrically connected to an external power source through a control switch. The motor 7 is fixedly installed on the outer wall of the cylinder 5. The output end of the motor 7 passes through the cylinder 5 and is fixedly provided with a gear 10. The upper end of the rotating ring 11 is provided with gear teeth, which mesh with the gear 10.

[0024] A liquid storage tank 4 is fixedly installed on the outer wall of the cylinder 5. An annular tube 13 is provided on the outside of the rope 1 at the lower side of the rotating ring 11. Multiple spray holes are evenly provided on the inner side of the annular tube 13. A liquid outlet pipe 12 is fixedly installed at the bottom of the liquid storage tank 4. One end of the liquid outlet pipe 12 passes through the cylinder 5 and is fixedly connected to the annular tube 13. A water pump and a valve are provided on the liquid outlet pipe 12.

[0025] An atomizing nozzle 14 is installed at the nozzle, which can atomize the seawater cleaning solution, thereby improving the seawater cleaning effect. The storage tank 4 contains seawater cleaning solution, and the top of the storage tank 4 is provided with a liquid inlet 3, which allows the seawater cleaning solution to be easily introduced into the storage tank 4.

[0026] In use, when the winch on the crane begins to wind rope 1, rope 1 rises. The motor 7 and water pump are started, and the valves are opened. After the valve on the outlet pipe 12 is opened, the seawater cleaning solution in the storage tank 4 enters the outlet pipe 12. After being pressurized by the water pump, it is atomized through multiple atomizing nozzles 14 on the annular pipe 13 and evenly sprayed onto rope 1. The motor 7 drives the gear 10 to rotate, and the gear 10 drives the rotating ring 11 to rotate through the gear teeth. At the same time, the rotating ring 11 drives the brush 9 to clean the circumference of rope 1. It can clean rope 1 simultaneously as it rises. This not only has a good cleaning effect on rope 1, but also makes rope 1 less susceptible to seawater corrosion, thus increasing the service life of rope 1. It also reduces the labor intensity of workers and improves safety.

[0027] 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.
