Description

Technical Field

[0001] This invention relates to wire rope protection devices, and more specifically, to a detachable wire rope sealing protection device. Background Technology

[0002] Wire rope is a flexible rope made of multiple strands of thin steel wire twisted together. It is an important component with high strength, good elasticity, light weight, and good flexibility, playing a role in lifting, traction, tensioning, and load bearing in material handling machinery. However, due to harsh working environments and large load impacts, wire ropes can experience fatigue, corrosion, wear, and even sudden breakage during use. Its actual condition is related to the safety of equipment and personnel.

[0003] In near-shore ports, steel wire ropes may come into contact with or even be submerged in seawater under certain working conditions. Seawater is highly corrosive, and prolonged exposure to seawater will cause corrosion of the wire rope, reducing its strength, accelerating fatigue fracture, and creating safety hazards. Existing wire rope protection devices can effectively protect the wire rope from cuts and abrasions by other equipment, but most of these devices are not effective against seawater corrosion. Some protection devices designed specifically for seawater corrosion have drawbacks such as inconvenient disassembly and installation, and the inability to install them underwater. Even after underwater installation, seawater may remain inside the device, reducing its protective effect on the wire rope and rendering it ineffective. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a detachable wire rope sealing and protection device that is simple in structure, easy to assemble and disassemble, can effectively seal, and extend the service life of wire rope.

[0005] The technical solution adopted by this invention to solve its technical problem is as follows: A detachable wire rope sealing and protection device is constructed, comprising a first semi-cylindrical metal outer shell and a second semi-cylindrical metal outer shell. The cylindrical sides of the first and second metal outer shells are hinged together. A mating piece is provided on the other cylindrical side of the first and second metal outer shells. A guide sleeve is provided on the outer side of the bottom surface of the first and second metal outer shells, and a sealing ring is provided inside the guide sleeve. A track groove is provided on the inner side of the bottom surface of the first and second metal outer shells, and a fixing rod is provided in the track groove. Connecting rods are provided on both sides of the fixing rod, and elastic sealing membranes are provided on both sides of the connecting rod. A gap is left between the bottom surface of the first and second metal outer shells and the track groove to form a sealed cavity. A protruding button is provided in the middle of the first and second metal outer shells. The button is connected to the fixing rod by a spring and is connected by a connecting rod with a hook.

[0006] According to the above scheme, the cylindrical side connection of the first metal shell body and the second metal shell body is provided with interlocking grooves and protrusions to achieve a sealed connection.

[0007] According to the above scheme, a rotating shaft is provided on the cylindrical side of the first metal shell body, and a rotating groove corresponding to the rotating shaft is provided on the cylindrical side of the second metal shell body. The cylindrical sides of the first metal shell body and the second metal shell body are movably connected through the rotating shaft and the rotating groove.

[0008] According to the above scheme, a through hole is provided on the middle surface of the first metal shell body and the second metal shell body, and the button is disposed in the through hole.

[0009] According to the above scheme, the fixing rod is provided with a limiting groove for the normal movement of the button.

[0010] According to the above scheme, the connecting rod is provided with a hook groove that can be connected to the hook body.

[0011] According to the above scheme, the sealed cavity is provided with an elastic water-absorbing material.

[0012] According to the above scheme, the first metal outer shell body and the second metal outer shell body are provided with three docking pieces, which correspond one-to-one.

[0013] According to the above scheme, the mating piece is provided with holes, and the mating piece provided on the first metal shell body and the mating piece provided on the second metal shell body are bolted together.

[0014] The detachable wire rope sealing protection device of the present invention has the following advantages:

[0015] This invention features a simple structure. The hinged connection between the cylindrical sides of the first and second metal outer shells makes the overall structure more compact and facilitates installation and disassembly. When installed on water, simply installing this sealing protection device effectively prevents wear and seawater corrosion. When installed underwater, pressing a button after installing the sealing protection device absorbs moisture from the surface of the wire rope. The interlocking grooves and protrusions at the connection point of the cylindrical sides of the first and second metal outer shells further prevent seawater from overflowing into the device from both sides. The sealing ring inside the guide sleeve on the outer bottom surface further prevents seawater from overflowing into the device from the bottom. This invention provides dual protection against wear and seawater corrosion for the wire rope while offering convenient use, significantly increasing its service life. Attached Figure Description

[0026] like Figure 1-8 As shown, a detachable wire rope sealing and protection device of the present invention includes a first metal outer shell body 12 and a second metal outer shell body 13, both semi-cylindrical. The cylindrical sides of the first metal outer shell body 12 and the second metal outer shell body 13 are hinged to each other. A rotating shaft 6 is provided on the cylindrical side of the first metal outer shell body 12, and a rotating groove corresponding to the rotating shaft 6 is provided on the cylindrical side of the second metal outer shell body 13. The cylindrical sides of the first metal outer shell body 12 and the second metal outer shell body 13 are movably connected through the rotating shaft 6 and the rotating groove. The connection between the cylindrical sides of the first metal outer shell body 12 and the second metal outer shell body 13 is provided with interlocking grooves and protrusions for sealing and mating.

[0027] A mating piece 1 is provided on the other cylindrical side of the first metal outer shell 12 and the second metal outer shell 13. There are three mating pieces 1 on the first metal outer shell 12 and the second metal outer shell 13, corresponding one-to-one. The mating piece 1 has holes, and the mating pieces 1 on the first metal outer shell 12 and the mating pieces 1 on the second metal outer shell 13 are bolted together. A guide sleeve 9 is provided on the outer side of the bottom surface of the first metal outer shell 12 and the second metal outer shell 13. A sealing ring 10 is provided inside the guide sleeve 9. A track groove 4 is provided on the inner side of the bottom surface of the first metal outer shell 12 and the second metal outer shell 13. A fixing rod 3 is provided in the track groove 4. A connecting rod 5 is provided on both sides of the fixing rod 3. An elastic sealing membrane 7 is provided on both sides of the connecting rod 5. A gap is left between the bottom surface of the first metal outer shell 12 and the second metal outer shell 13 and the track groove 4 to form a sealed cavity 8. An elastic water-absorbing material is provided in the sealed cavity 8.

[0028] A raised button 2 is provided in the middle of the first metal outer shell body 12 and the second metal outer shell body 13. A through hole 11 is provided on the surface of the middle part of the first metal outer shell body 12 and the second metal outer shell body 13, and the button 2 is disposed in the through hole 11. The button 2 is connected to the fixing rod 3 by a spring 21. The fixing rod 3 is provided with a limiting groove 23 for the normal movement of the button 2. The button 2 is connected by a connecting rod 5 that moves with the hook body 22. The connecting rod 5 is provided with a hook groove that can be connected to the hook body 22.

[0029] In a preferred embodiment of the present invention, the main body consists of two metal shells, which are combined and connected to form a cylinder. A rotating shaft 6 is provided on one side of the cylindrical surface of the first metal shell 12, and a rotating groove corresponding to the rotating shaft 6 is provided on the second metal shell 13. The first metal shell 12 and the second metal shell 13 are fixed and rotated on one side via the rotating shaft 6 and the rotating groove. A mating piece 1 is provided on the other side of the first metal shell 12 and the second metal shell 13. There are six mating pieces in total for the two metal shells. The mating pieces 1 have holes and are connected and fixed by bolts, allowing for free disassembly. A semi-cylindrical groove and a protrusion are provided on the inner side of the connection between the first metal shell 12 and the second metal shell 13. The semi-cylindrical protrusion is inserted into the groove, achieving an effective seal and providing waterproofing. Guide sleeves 9 are provided at both ends of the first metal shell 12 and the second metal shell 13. Sealing rings 10 are installed on the inner wall of the guide sleeves 9. The sealing rings 10 are made of waterproof rubber, effectively preventing seawater from entering the inner cavity of the device from both ends. The first metal housing body 12 and the second metal housing body 13 each have a through hole 11 in their middle portions for mounting a button 2. One end of the button 2 is exposed outside the metal housing, and the other end of the button 2 is connected to a fixing rod 3. The fixing rod 3 is fixed to the inner side of the middle portion of the metal housing body, and both ends of the fixing rod 3 are fixed to the middle portion of the track groove 4. Connecting rods 5 are respectively provided on both sides of the fixing rod 3. A hook groove is provided in the middle portion of one side of the connecting rod 5, and the hook body 22 of the button 2 can hook into the hook groove of the connecting rod 5.

[0030] like Figure 5 As shown, button 2 and fixing rod 3 are connected by spring 21. Spring 21 ensures that when the button 2 is stationary, the hook 22 can engage with the hook groove of connecting rod 5, preventing connecting rod 5 from releasing automatically. A limiting groove 23 is provided in the middle of fixing rod 3 to ensure the normal range of motion of button 2. Figure 6-7 As shown, the inner sides of both ends of the first metal outer shell 12 and the second metal outer shell 13 are provided with track grooves 4. The outer side of the connecting rod 5 is an elastic sealing membrane 7, which is a highly elastic rubber membrane. One side of the elastic sealing membrane 7 is fixed to the inner side of the metal outer shell, and the other side of the elastic sealing membrane 7 is bonded to the connecting rod 5 and can slide along the track groove 4, forming a sealed cavity 8 between the elastic sealing membrane 7 and the metal outer shell. When button 2 is pressed, the connecting rod 5 is released. Since the elastic sealing membrane 7 was previously in a stretched state, after the connecting rod 5 is released, the connecting rod 5 and the elastic sealing membrane 7 together spring back to both sides of the device along the track groove 4, and the sealed cavity 8 opens. The sealed cavity 8 is filled with elastic water-absorbing material, such as highly elastic sponge. After the sealed cavity 8 opens, the elastic water-absorbing material pops out and can absorb moisture on the surface of the wire rope. When this sealing protection device is installed underwater, the elastic sealing membrane 7 plays a role in blocking the elastic water-absorbing material from seawater.

[0031] The method of using this invention is as follows:

[0032] When installing on water, the wire rope has not been in contact with seawater before use, and there is no moisture adhering to its surface. Simply rotate the first metal outer shell 12 and the second metal outer shell 13 along the rotating shaft 6 to open them by a certain angle, insert the wire rope, close the two metal outer shells, and fix the mating pieces 1 on the sides of the two metal outer shells with nuts to complete the assembly. At this point, the wire rope can be used on water or submerged underwater, effectively preventing seawater corrosion and further increasing its service life.

[0033] During underwater installation, since the wire rope is already submerged in seawater, seawater adheres to its interior and surface. After rotating the first metal outer shell 12 and the second metal outer shell 13 along the rotating shaft 6 to open them by a certain angle, the wire rope is inserted, and the two metal outer shells are closed. After securing the mating pieces 1 on the sides of the metal outer shells with nuts, the button 2 and hook 22 need to be pressed to release the connecting rod 5. Due to the high elasticity of the elastic sealing membrane 7, it bounces back to both sides of the metal outer shell along the track groove 4 along with the connecting rod 5. At this time, the elastic absorbent material in the sealing cavity 8 pops out, contacts the surface of the wire rope, and absorbs the seawater adhering to the wire rope, keeping it dry and further improving its waterproofness and protection, thus increasing its service life. The sealing rings 10 on the inner sides of both ends effectively prevent seawater from entering the internal space from both ends of the device, further ensuring the sealing effect.

[0034] When installing in a humid environment, the surface of the wire rope will already be covered with a lot of moisture. After the sealing and protection device is installed, button 2 should be pressed to allow the absorbent material to absorb the moisture attached to the wire rope and enhance the protection of the wire rope.

[0035] This invention can be assembled and disassembled both above and below water, achieving a sealed and waterproof protection for the wire rope. Furthermore, the entire assembly and disassembly operation can be completed by a single person, offering great convenience. For secondary use, only the elastic absorbent material inside the sealing cavity 8 needs to be replaced, significantly reducing operating costs.

[0036] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
