Description

Technical Field

[0001] This invention relates to the field of mechanical hand tools, specifically a U-shaped ratchet steel wire rope reinforcement and disassembly tool. Background Technology

[0002] In modern military railway transportation, wire rope fastening devices, especially U-shaped ratchet wire rope fasteners, are widely used for the rapid construction and dismantling of temporary guy wire systems due to their self-locking reliability and convenient adjustment. They are a crucial component in tasks such as railway restoration, equipment reinforcement, and emergency obstacle removal, and their operational efficiency directly affects the battlefield mobility and survivability of troops.

[0003] However, under the current operating model, completing a full wire rope tightening or loosening operation typically requires operators to use multiple tools sequentially, including at least: a wrench for initial pre-tightening, a lever for overcoming the enormous tension during final tightening or dismantling, and ripping pliers for cutting the wire rope in emergencies. This decentralized, single-function tool configuration reveals significant tactical shortcomings under harsh field conditions. Summary of the Invention

[0004] To address the aforementioned technical problems, this invention provides the following technical solution: A U-shaped ratchet wire rope reinforcement and dismantling tool includes a housing, within which a worm gear is rotatably mounted. One end of the worm gear has a drive assembly, and the worm gear meshes with a worm wheel rotatably mounted within the housing. A worm wheel shaft is fixedly mounted at the center of the worm wheel, and the worm wheel shaft is rotatably mounted on the housing. A drive ring is fixedly mounted at one end of the worm wheel shaft, and a fixed post is eccentrically mounted on the drive ring. The fixed post is slidably mounted in an annular groove, which is located on a moving blade. The moving blade is rotatably mounted on a fixed blade via a blade shaft, and the fixed blade is fixedly mounted on one side of the housing. A wrench head is detachably mounted at the other end of the worm wheel shaft via a spline, and the wrench head has a drive groove for driving bolt rotation. A nail puller is fixedly mounted on the housing, and the nail puller has a V-shaped opening for nail removal. A hammer head is fixedly mounted on the nail puller, and the hammer head forms a fulcrum with the contact surface during nail removal.

[0005] Furthermore, the worm is rotatably mounted on the top of the housing via worm bearing one and worm bearing two located at its two ends.

[0006] Furthermore, the worm gear shaft is rotatably mounted on the housing via worm gear bearing one and worm gear bearing two located at its two ends.

[0007] Furthermore, the drive assembly includes a crank handle detachably mounted at the end of the worm gear via a spline, and a rotatable handle made of rubber material is mounted on the crank handle.

[0008] Furthermore, a cutter shaft sleeve is threaded onto the end of the cutter shaft, which is used to limit the positions of the fixed cutter and the moving cutter.

[0009] Furthermore, a handle is provided on one side of the housing, and the handle is detachably connected to the housing by bolts.

[0010] The advantages of this invention compared to the prior art are: 1. Multifunctional Integration for Enhanced Work Efficiency: This invention integrates multiple functions such as a wrench, lever, wire cutters, and nail pullers into one unit, solving the problem of needing to carry multiple tools and frequently change them in existing field operations. Operators only need to carry one tool to complete multiple tasks such as tightening, disassembling, cutting, and nail removal of wire ropes, significantly improving on-site work efficiency and adapting to the needs of rapid deployment and emergency response.

[0011] 2. This invention utilizes a worm gear transmission mechanism, taking advantage of its speed reduction and torque amplification characteristics. Operators can easily drive the wrench head to rotate via a crank handle, enabling the tightening or loosening of high-tension nuts, significantly reducing the intensity of manual operation. Simultaneously, the self-locking characteristic of the worm gear ensures safety during operation.

[0012] 3. This invention achieves rapid cutting of steel wire by setting a moving blade and a fixed blade structure on one side of the housing, combined with the eccentric transmission of the drive ring and the fixed column. This structure is simple and reliable, suitable for the destructive dismantling of steel wire ropes in emergency situations, and improves the tool's emergency handling capabilities.

[0013] 4. The wrench head of this invention adopts a splined detachable structure, allowing users to quickly replace it with the appropriate model according to the nut specifications, thus improving the tool's versatility and adaptability. The handle, crank, and other components are also detachable for easy carrying and storage.

[0014] 5. This invention integrates nail pullers and a hammer head, which facilitates quick nail removal in field environments. The hammer head acts as a fulcrum, saving effort and further expanding the applicable scenarios of the tool, thus enhancing its practical value.

[0015] 6. The functional modules of this invention are compactly arranged around the shell, with a reasonable overall structure, small size, and light weight, making it easy for individual soldiers to carry and deploy in the field, which meets the requirements of modern military engineering support for lightweight and multifunctional tools.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1 to 5As shown, a U-shaped ratchet wire rope reinforcement and dismantling tool includes a worm gear 1, a worm 2, nail pullers 3, a worm bearing 1 4, a worm bearing 2 5, a crank handle 6, a handle 7, a hammer head 8, a worm gear bearing 1 9, a wrench head 10, a fixing post 11, a worm gear bearing 2 12, a worm gear shaft 13, a drive ring 14, a moving blade 15, a fixed blade 16, an annular groove 17, a housing 18, a handle 19, a blade shaft 20, and a blade shaft sleeve 21. A worm gear 2 is rotatably mounted inside the housing 18. One end of the worm gear 2 is equipped with a drive assembly. The worm gear 2 meshes with a worm wheel 1 rotatably mounted inside the housing 18. A worm wheel shaft 13 is fixedly mounted at the center of the worm wheel 1. The worm wheel shaft 13 is rotatably mounted on the housing 18. A drive ring 14 is fixedly mounted at one end of the worm wheel shaft 13. A fixing post 11 is fixedly mounted on the drive ring 14 at a position offset from its center. The fixing post 11 is slidably mounted in an annular groove 17, which is located on a moving cutter 15 and extends through both surfaces of the moving cutter 15. The moving cutter 15 is rotatably mounted on a fixed cutter 16 via a cutter shaft 20. The fixed cutter 16 is fixedly mounted on one side of the housing 18. A wrench head 10 is detachably mounted at the other end of the worm wheel shaft 13 via a spline. The wrench head 10 has a drive groove for driving the bolt rotation. During use, the wrench head 10 can be replaced with a model suitable for the nut to be disassembled or assembled, and then reinstalled to achieve the tightening and loosening of the nut. A nail puller 3 is fixedly mounted on the housing 18. The nail puller 3 has a V-shaped opening for pulling out nails. A hammer head 8 is fixedly mounted on the nail puller 3. The hammer head 8 is used to form a fulcrum with the contact surface when pulling out nails, so as to pull out nails quickly and effortlessly.

[0024] like Figures 1 to 5 As shown, in a preferred embodiment, the worm 2 is rotatably mounted on the top of the housing 18 via worm bearing 4 and worm bearing 5 located at its two ends.

[0025] like Figures 1 to 5 As shown, in a preferred embodiment, the worm shaft 13 is rotatably mounted on the housing 18 via worm bearing 9 and worm bearing 12 located at its two ends.

[0026] like Figures 1 to 5 As shown, as a preferred embodiment, further in this embodiment, the drive assembly includes a crank 6 detachably disposed at the end of the worm gear 2 via a spline, and a handle 7 rotatably disposed on the crank 6, the handle 7 being made of rubber material.

[0027] like Figures 1 to 5 As shown, in a preferred embodiment, in this embodiment, the end of the cutter shaft 20 is provided with a cutter shaft sleeve 21 by means of a thread, and the cutter shaft sleeve 21 is used to limit the position of the fixed cutter 16 and the moving cutter 15.

[0028] like Figures 1 to 5 As shown, as a preferred embodiment, in this embodiment, a handle 19 is provided on one side of the housing 18, and the handle 19 is detachably connected to the housing 18 by bolts.

[0029] like Figures 1 to 5 As shown, the working principle of the U-shaped ratchet steel wire rope reinforcement and dismantling tool disclosed in this invention is as follows: When it is necessary to cut the steel wire, the operator manually drives the crank handle 6 to rotate through the handle 7. The rotation of the crank handle 6 drives the worm gear 2 to rotate, which in turn drives the worm wheel 1 and the worm wheel shaft 13 to rotate. When the worm wheel shaft 13 rotates, it drives the drive ring 14 and the fixed column 11 to rotate together. When the drive ring 14 rotates, it drives the moving blade 15 to reciprocate on the fixed blade 16 through the annular groove 17. At this time, the steel wire to be cut is inserted into the cutting edge of the moving blade 15 and the fixed blade 16. The relatively rotating moving blade 15 and the fixed blade 16 cut the steel wire.

[0030] When it is necessary to remove or install a nut, replace the wrench head 10 with a model that is compatible with the nut to be removed or installed, and then insert it into the worm gear shaft 13 for installation and reset. Then, the nut can be turned in two ways to achieve removal or installation. Specifically: Method 1: Since the worm 2 and worm wheel 1 have self-locking properties, when installing or removing the nut using the wrench head 10, the operator can hold the handle 19 and use the entire device as a tool to turn the wrench head 10, thereby achieving the installation or removal of the nut.

[0031] Method 2: Since the worm 2 and worm wheel 1 are a typical speed reduction and torque increase mechanism, the operator can also rotate the crank handle 6 by the handle 7. The rotation of the crank handle 6 drives the worm 2 to rotate, which in turn drives the worm wheel 1 and worm wheel shaft 13 to rotate. The rotation of the worm wheel shaft 13 drives the wrench head 10 to rotate, thereby realizing the installation or removal of the nut.

[0032] When nails need to be removed, the operator holds the handle 19 and uses the nail pullers 3 to pull out the nail. At the same time, the hammer head 8 is used as a fulcrum to save effort, and the nail can be easily pulled out.

[0033] The entire device integrates multiple practical functions. By reducing the difficulty of operation through the labor-saving characteristics of the worm gear 1 and worm 2, it can easily meet a variety of needs.
