Description

Technical Field

[0001] This invention relates to the field of wire rope straightening technology, and in particular to a wire rope straightening machine and straightening process for marine engineering cranes. Background Technology

[0002] High breaking strength steel wire ropes used in marine engineering cranes are prone to bending, twisting, or residual stress during manufacturing and transportation, affecting their stability and load-bearing capacity during use. The role of a straightening machine is to eliminate the initial bending of the wire rope through rollers, tensioning, or straightening devices, improve its straightness, make it bear the load more evenly, reduce local stress concentration, and extend its service life. The straightening machine can also optimize the arrangement of the wire rope, ensure its smooth operation on the drum or pulley, avoid instability caused by deformation, and improve the safety and reliability of marine engineering crane operations.

[0003] In existing wire rope straightening machines, the paired pressure rollers used to straighten wire ropes are prone to leaving metal particles inside the grooves during operation. If these metal particles are not cleaned in time, the straightening machine can easily press them into the wire rope, causing surface damage or localized hardening, reducing its flexibility and fatigue resistance. Embedded metal particles may also cause localized stress concentration, increasing the risk of wire breakage or fatigue fracture, affecting the service life and safety of the wire rope. In high-load or marine environments, this defect may exacerbate corrosion and wear, reduce the reliability of the wire rope, and even cause equipment failure or safety accidents. Summary of the Invention

[0004] The purpose of this invention is to solve the problem that in the existing wire rope straightening machine, the paired pressure rollers used for straightening wire ropes easily retain metal particles inside the grooves during operation. If the metal particles are not cleaned in time, the straightening machine can easily press the metal particles into the wire rope, causing damage or local hardening to the wire rope surface, reducing its flexibility and fatigue resistance. The embedded metal particles may also cause local stress concentration, increasing the risk of wire breakage or fatigue fracture, affecting the service life and safety of the wire rope. Therefore, this invention proposes a wire rope straightening machine for marine engineering cranes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A wire rope straightening machine for marine engineering cranes includes a support platform, a top pressure roller, and a bottom pressure roller. A starting support plate, a U-shaped frame, and an end support plate are sequentially fixed on the top of the support platform. Rectangular grooves are formed on the left and right sides of the U-shaped frame. A metal particle adsorption component is provided at the rectangular groove position of the U-shaped frame. The metal particle adsorption component recovers metal particles attached to the surface of the top and bottom pressure rollers to prevent metal particles from affecting the straightening quality of the wire rope. The metal particle adsorption component includes an adsorption block, a first crossbar, a first electrical contact plate, and a second electrical contact plate.

[0007] A transfer cylinder is fixedly installed on the side of the rectangular groove of the support platform. A mounting baffle is fixedly installed at the output end of the transfer cylinder. A vertical plate is fixedly installed on the side of the mounting baffle of the rectangular groove. A guide plate is fixedly installed at the top of the side of the vertical plate. A recycling component is installed at the bottom of the guide plate. The recycling component is used to store the particles adsorbed by the metal particle adsorption component.

[0008] The adsorption block is provided with a path guiding component on the top side. The path guiding component can control the adsorption block to move out of the grooves of the top pressure roller and the bottom pressure roller, and then move to the top of the recycling component, so as to facilitate the adsorption block to release metal particles into the recycling component.

[0009] A continuous power supply component is provided on the side of the vertical plate. The continuous power supply component enables the metal particle adsorption component to obtain power in the grooves of the top and bottom pressure rollers, thereby adsorbing metal particles based on the principle of electromagnetism. The continuous power supply component loses power above the recycling component, which facilitates the release of metal particles by the metal particle adsorption component.

[0010] An automatic demagnetizing component is additionally provided on the side of the adsorption block. The automatic demagnetizing component prevents the adsorption block from having a residual magnetic field when the continuous power supply component stops supplying power to the metal particle adsorption component, thus preventing residual metal particles from remaining on the adsorption block.

[0011] Optionally, the top of the U-shaped frame is symmetrically fixed with top columns, and the top columns are rotatably connected with top pressure rollers. The bottom of the U-shaped frame is fixed with a support plate, and the top of the support plate is symmetrically fixed with bottom columns.

[0013] The starting support plate is symmetrically and rotatably connected to the top side of the plate. The guide rollers are used to guide the wire rope into the straightening structure composed of a pair of top pressure rollers and bottom pressure rollers.

[0014] Optionally, the recycling assembly includes an extension column, a recycling hopper, and a top cover plate. The top of the extension column is fixedly connected to the side of the guide plate, and the bottom of the extension column is fixedly located at the top edge of the top cover plate. A docking screw is fixedly located at the top of the recycling hopper. A U-shaped groove is provided on the top of the top cover plate, and a fixing bolt is screwed into the docking screw after it passes through the U-shaped groove.

[0015] Optionally, the path guiding component includes a mounting block, an extension block, a drive column, a rectangular column, and a contact spring. The adsorption block has an arc-shaped groove on its side. The mounting block is fixedly mounted on the side opposite the arc-shaped groove. The rectangular column is fixedly mounted on the side of the mounting block. The rectangular column is movably inserted into the side of the mounting plate. The outer wall of the rectangular column is fixedly connected to one end of the contact spring. The other end of the contact spring is fixedly connected to the side of the mounting plate. An extension block is fixedly mounted at the top edge of the mounting block. The drive column is fixedly mounted on the side of the extension block. The guide plate has an inclined surface on one side of the drive column. One end of the drive column is in contact with the inclined surface.

[0016] Optionally, the adsorption block has an adsorption core fixedly installed on the bottom side of the mounting block, a second crossbar fixedly installed on one side of the adsorption core, a top block fixedly installed at the end of the second crossbar, a bottom terminal post fixedly installed at the edge of the side of the second crossbar, a top terminal post fixedly installed on the side of the top block, an electric wire wound around the outer wall of the adsorption core, and the two ends of the electric wire wound around the outer wall of the adsorption core are respectively fixed to the bottom terminal post and the top terminal post. The continuous power supply component includes a top plate and a bottom plate, and the side of the vertical plate has a top horizontal groove and a bottom horizontal groove sequentially opened along the vertical direction.

[0017] Optionally, a top connecting plate is movably inserted into the top transverse groove, and a bottom connecting plate is movably inserted into the bottom transverse groove. Connecting columns are fixedly provided on the sides of both the top and bottom connecting plates. A common vertical rod is fixedly provided at the ends of the two connecting columns. A return spring is fixedly provided at the middle position of the side of the common vertical rod. A mounting base is fixedly connected to the other end of the return spring. The mounting base is fixedly connected to the side of the vertical plate.

[0018] Optionally, the automatic demagnetizing assembly includes a demagnetizing core, a first electrical contact plate, a second electrical contact plate, and an electrical contact block. The adsorption block is provided with the demagnetizing core at the same horizontal height as the adsorption core, and a first crossbar is fixedly provided on the side of the adsorption block with respect to the demagnetizing core.

[0019] Optionally, a first contact plate and a second contact plate are fixedly provided on the side of the first crossbar in sequence, and the outer wall of the demagnetizing core is also wound with wires, the wires wound on the outer wall of the demagnetizing core having the opposite winding direction to the wires wound on the outer wall of the adsorption core.

[0020] Optionally, the two ends of the wire wound around the outer wall of the demagnetizing core are fixed to the first and second contact plates in sequence. Two contact blocks are fixedly provided on the top of the top cover plate. The two contact blocks are connected to the positive and negative terminals of an external power source. The top and bottom contact plates are connected to the positive and negative terminals of another power source.

[0021] A process for straightening and straightening steel wire ropes for marine engineering cranes includes the following steps:

[0022] S1: The straightening machine performs straightening and metal particle adsorption. The metal particle adsorption component is located on the side of the top and bottom pressure roller grooves to adsorb the metal particles present on the top and bottom pressure rollers. After the worker passes the steel wire rope to be straightened through the paired guide rollers, top and bottom pressure rollers, it is finally wound around the outer wall of the take-up roller.

[0023] S2: The metal particle adsorption component is moved to the recycling component for unloading. During this process, the path guide component moves the metal particle adsorption component out of the grooves of the top and bottom pressure rollers and moves it above the recycling component. At this time, the continuous power supply component cannot supply power to the metal particle adsorption component. The automatic demagnetizing component also works to eliminate the magnetic field remaining on the adsorption block by the continuous power supply component, releasing all particles on the adsorption block into the recycling hopper.

[0024] Compared with the prior art, the present invention has the following advantages:

[0025] 1. The components responsible for the straightening function in this invention are the top pressure roller and the bottom pressure roller. A metal particle adsorption component based on the principle of electromagnetism is provided on the sides of the top and bottom pressure rollers. This component can promptly adsorb residual metal particles inside the sides of the top and bottom pressure rollers onto the adsorption blocks on the metal particle adsorption component. This solves to a certain extent the problem in existing wire rope straightening machines where metal particles easily remain inside the grooves of the paired pressure rollers during operation. If these metal particles are not cleaned in time, the straightening machine can easily press them into the wire rope, causing surface damage or localized hardening, reducing its flexibility and fatigue resistance. Furthermore, embedded metal particles may cause localized stress concentration, increasing the risk of wire breakage or fatigue fracture.

[0026] 2. The present invention provides a recovery component, a path guiding component, a continuous power supply component, and an automatic demagnetizing component near the metal particle adsorption component. When the transverse cylinder on one side is activated, the transverse cylinder, in cooperation with the path guiding component and the continuous power supply component, moves the metal particle adsorption component out from inside the top and bottom pressure rollers and onto the recovery component, thereby timely removing the metal particles adsorbed by the metal particle adsorption component and preventing the metal particle adsorption component from adsorbing too many particles, which would affect the adsorption capacity of the metal particle adsorption component.

[0027] 3. The path guiding component, continuous power supply component, and automatic demagnetizing component of this invention are interconnected. A single lateral movement cylinder controls the path guiding component's movement between the adsorption and release stations. Simultaneously, the continuous power supply component physically stops supplying power to the metal particle adsorption component. When the metal particle adsorption component reaches the recycling station, it automatically releases the metal particles to the recycling component, avoiding additional electrical control and improving system reliability. Furthermore, the physical structure controls the start and stop of power supply, ensuring precise synchronization between the adsorption and release processes, preventing metal particle residue and improving cleaning efficiency.

[0028] 4. The present invention is additionally provided with an automatic demagnetizing component. The continuous power supply component uses the magnetic field formed by the metal particle adsorption component to adsorb metal particles. After the metal particle adsorption component is powered off, the automatic demagnetizing component can automatically form a magnetic field in the opposite direction to the continuous power supply component, thereby canceling the magnetic field remaining in the metal particle adsorption component and avoiding residual magnetic force on the adsorption block, which would prevent the adsorbed metal particles from being completely released.

[0047] Reference Figure 5-12A path guiding component is provided on the top side of the adsorption block 28.

The continuous power supply component enables the metal particle adsorption component to obtain power in the grooves of the top pressure roller 8 and the bottom pressure roller 9, thereby adsorbing metal particles based on the principle of electromagnetism.

[0049] An automatic demagnetizing component is additionally provided on the side of the adsorption block 28.

The automatic demagnetizing component includes a demagnetizing core 32, a first contact plate 30, a second contact plate 31, and a contact block 251.

The two ends of the wires wrapped around the outer wall of the demagnetizing core 32 are fixed to the first power plate 30 and the second power plate 31 in sequence. Two power blocks 251 are fixedly installed on the top of the top cover plate 25. The two power blocks 251 are connected to the positive and negative terminals of an external power source. The top connecting plate 17 and the bottom connecting plate 22 are connected to the positive and negative terminals of another power source.

[0050] It should be added that the positions of the two electrical blocks 251 need to be installed properly to ensure that they are on the oblique movement paths of the first electrical block 30 and the second electrical block 31.

[0051] The specific implementation steps and principles of this invention are as follows:

[0052] The straightening machine performs straightening and metal particle adsorption operations. The metal particle adsorption component is located on the side of the grooves of the top pressure roller 8 and the bottom pressure roller 9. After the worker passes the steel wire rope to be straightened through the paired guide rollers 1, top pressure roller 8, and bottom pressure roller 9, it is finally wound around the outer wall of the take-up roller 301. At this time, the top contact plate 17 and the bottom contact plate 22 are in contact with the top contact post 40 and the bottom contact post 42, respectively. The adsorption iron core 33 makes the adsorption block 28 magnetic, adsorbing the metal particles present on the top pressure roller 8 and the bottom pressure roller 9.

[0053] The metal particle adsorption assembly is moved to the recycling assembly for unloading. During this process, the path guide assembly moves the metal particle adsorption assembly out of the grooves of the top pressure roller 8 and bottom pressure roller 9 and onto the recycling assembly. Specifically, the drive column 35 moves along the plane of the vertical plate 16 and the inclined surface 231 of the guide plate 23. During this process, the adsorption block 28 first moves laterally out of the grooves of the top pressure roller 8 and bottom pressure roller 9. During this process, the top contact plate 17 and bottom contact plate 22 contact the top contact post 40 and bottom contact post 42, respectively. The adsorption iron core 33 ensures that the adsorption block 28 still has magnetism, and then it moves longitudinally. During the process of moving to the top of the recycling hopper 13, the top plate 17 and the bottom plate 22 separate from the top electrode post 40 and the bottom electrode post 42, respectively. The adsorption block 28 loses its magnetic force and pours the metal particles into the recycling hopper 13. During this process, the automatic demagnetizing component also works to eliminate the magnetic field left on the adsorption block 28 by the continuous power supply component. Specifically, the first electrode plate 30 and the second electrode plate 31 briefly come into contact with the two electrode blocks 251 during the oblique movement. The demagnetizing core 32 generates a magnetic field in the opposite direction to that of the adsorption core 33, thus canceling out the magnetic field left on the adsorption core 33.

[0054] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
