Description

Technical Field

[0001] This invention relates to the field of wire rope pulling and stranding technology, and in particular to stranding equipment and processing technology for processing high-strength wire ropes for cranes. Background Technology

[0002] The high-strength steel wire rope for cranes undergoes a stranding process. The core of this process involves spirally winding multiple steel wires together with a specific lay direction and pitch, giving the wire rope both structural strength and flexibility. Individual steel wires are rigid and easily broken; however, stranding creates a stress-dispersing structure between the wires, enabling it to withstand the tensile and bending loads during crane lifting and luffing. This also improves torsional and fatigue resistance, preventing single-wire breakage under stress. This lays the foundation for subsequent rope-making processes, ensuring the wire rope is suitable for the heavy-duty operation requirements of the crane.

[0003] Currently, the stranding equipment for processing high-strength steel wire ropes for cranes generally suffers from the defects of separating the drawing and stranding processes and low equipment integration. The raw steel wires must first be drawn to a specified diameter by the drawing equipment and then transferred to the stranding equipment for stranding. This multi-process transfer not only increases production time but also easily causes damage to the surface of the steel wires. At the same time, traditional equipment lacks real-time tension monitoring to achieve the function of automatically stopping to prevent wire breakage. After a single raw steel wire breaks, it is easy to cause multiple strands of steel wires to become entangled and the product to be scrapped. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing stranding equipment for processing high-strength steel wire ropes for cranes, which generally suffer from the separation of drawing and stranding processes and low equipment integration. The raw steel wires must first be drawn to a specified diameter using a drawing device before being transferred to a stranding device for stranding. This multi-step transfer not only increases production time but also easily causes damage to the steel wire surface. Furthermore, traditional equipment lacks real-time tension monitoring to achieve an automatic stop function to prevent wire breakage. The breakage of a single raw steel wire can easily lead to multiple strands tangling and product scrap. Therefore, this invention proposes a stranding device and its processing technology for processing high-strength steel wire ropes for cranes.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A stranding device for processing high-strength steel wire rope for cranes includes a workbench, a horizontal drum, and a winding reel. A left support frame is fixedly connected to the top of the workbench, and a horizontal drum is rotatably connected to the left support frame. A stranding gear is fixedly connected to one end of the horizontal drum, and a drawing disc is fixedly connected to one side of the horizontal drum on the side of the stranding gear. Raw material steel wire release components are arranged in a circular array on the side of the drawing disc, and the raw material steel wire release components release multiple strands of raw material steel wire simultaneously. The side of the twisting gear has a circular array of rectangular grooves, and the workbench is provided with a drawing and twisting integrated component on one side of the twisting gear to draw multiple strands of raw steel wire into a specified diameter and twist them into a single strand of steel wire rope. A right support frame is fixedly connected to the end of the workbench away from the horizontal cylinder. A winding wheel is rotatably connected to the right support frame. A belt drive assembly is provided at one end of the winding wheel's shaft. The belt drive assembly drives the winding wheel to rotate, continuously winding up the single strand of steel wire rope twisted by the integrated pulling and twisting assembly. A tension-sensing wire breakage stop assembly is provided in the rectangular groove to capture the pulling and twisting tension of multiple raw material steel wires. When the pulling and twisting tension of any raw material steel wire exceeds the preset tension, the belt drive assembly is controlled to stop driving the winding wheel to rotate.

[0006] Optionally, the raw material wire release assembly includes a feeding frame, a storage wheel, and a guide wheel. The feeding frame is fixedly arranged in a circular array on the side of the drawing disc. A horizontal column is rotatably connected to the top of one end of the feeding frame. One end of the horizontal column is movably inserted into the center position of the storage wheel. Locking bolts are screwed into both ends of the horizontal column.

[0007] Optionally, the feeding rack is fixedly connected to a support rod at equal intervals on one side of the storage wheel, the top of the support rod is rotatably connected to a guide wheel, and the pulling disc is provided with a pulling hole on one side of the guide wheel.

[0008] Optionally, the integrated drawing and twisting assembly includes a gathering cylinder, a guide cone, a twisting motor, and a lower drive gear. The bottom of the gathering cylinder is fixedly connected to a suspension seat, which is fixedly connected to the top of the workbench. The twisting motor is fixedly connected to the bottom of the workbench surface, and the output end of the twisting motor is fixedly connected to the lower drive gear.

[0009] Optionally, the lower drive gear meshes stably with the twisting gear, the worktable has an intermediate groove above the twisting gear, and the guide cone is fixedly connected to one end of the horizontal cylinder.

[0010] Optionally, the belt drive assembly includes a driven pulley, a driving pulley, a winding motor, a tensioning pulley, and an electric push rod. The winding motor is fixedly connected to the side of the fixed plate, the fixed plate is fixedly connected to the bottom of the worktable, the output end of the winding motor is fixedly connected to the driving pulley, and the driven pulley is concentrically fixedly connected to the shaft of the winding pulley.

[0011] Optionally, an edge groove is provided at the top edge of the workbench, an electric push rod is fixedly connected to the side of the edge groove, a fixed base is fixedly connected to the output end of the electric push rod, a tensioning wheel is rotatably connected to the side of the fixed base, and a common belt is sleeved on the outer wall of the tensioning wheel, the driven pulley, and the driving pulley.

[0012] Optionally, the tension-sensitive wire breakage stop assembly includes a fixed frame, a guide plate, a trigger post, a common ring, and a micro switch. A transmission wheel is symmetrically rotatably connected within the fixed frame. A guide post is fixedly connected to one end of the fixed frame. A retaining spring is sleeved on the outer wall of the guide post, and the other end of the retaining spring is sleeved on the outer wall of the fixed post. The fixed post is fixedly connected to the side of a rectangular groove. An insertion slot is formed on one side of the twisting gear within the rectangular groove. A guide plate is fixedly connected to the end of the fixed frame away from the guide post. The guide plate is movably inserted into the insertion slot. A zigzag groove is formed on the guide plate, and a drive post is movably inserted into the zigzag groove. A trigger post is fixedly connected to one end of the drive post, and the trigger post is movably inserted into the twisting gear.

[0013] Optionally, an application column is fixedly connected to the side of the common ring, and one end of the application column is fixedly connected to a retaining spring. The other end of the retaining spring is fixedly connected to the side of the intermediate seat. The intermediate seat is fixedly connected to the worktable, and the application column is movably inserted into the intermediate seat. A micro switch is fixedly connected to one end of the application column on the intermediate seat, and the micro switch is electrically connected to an electric push rod.

[0014] The processing technology for high-strength steel wire ropes used in cranes includes the following steps: During the wire rope pulling and twisting operation, the raw material wire release component simultaneously releases multiple raw material wires to the pulling disc and twisting gear. One end of the raw material wire passes through the pulling hole, the tension-sensing wire breakage stop component, and the gathering cylinder in sequence. The iron core wire passes through the horizontal cylinder and the guide cone in sequence. The pulling and twisting integrated component is activated to fix one end of the multiple raw material wires and one end of the iron core to the outer wall of the winding wheel. The belt drive component is activated to drive the winding wheel to wind up the wire rope. The anti-broken wire stop judgment is that when the tension-sensing wire breakage stop component senses that multiple strands of raw material steel wire exceed the preset tension, the tension-sensing wire breakage stop component controls the belt drive component to stop the winding wheel from winding.

[0015] Compared with the prior art, the present invention has the following advantages: 1. This equipment integrates a drawing and twisting assembly on the workbench, combining the drawing and sizing of raw steel wire with the twisting process in the same station. This eliminates the transfer steps in the traditional process, avoiding damage to the steel wire surface caused by friction and collision during transfer, effectively improving the surface quality of the steel wire rope. At the same time, the integrated operation mode significantly shortens the processing flow, reduces equipment investment and manual operation steps, and significantly improves the mass production efficiency of high-strength steel wire ropes for cranes.

[0016] 2. This equipment achieves synchronous release of multiple raw steel wires through the raw steel wire release component. Combined with the circular array layout of the drawing disc, it ensures that the tension of each steel wire is uniform before twisting, avoiding defects such as stress concentration and loose structure in the wire rope after twisting due to tension differences. The design of the guide wheel and the drawing hole accurately guides and limits the steel wire, ensuring that multiple steel wires gather and twist along the preset trajectory.

[0017] 3. This equipment is equipped with a tension-sensing wire breakage stop component, which can capture the tension changes of multiple raw material steel wires in real time during the drawing and twisting process. When any wire exceeds the preset tension, it can quickly trigger a stop command and control the belt drive component to stop winding. This effectively avoids problems such as multiple steel wires tangling and knotting caused by the continuous operation of the equipment after wire breakage, reduces the product scrap rate, and reduces the time cost of manually checking for wire breakage faults, ensuring the safety and continuity of the processing process.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] Reference Figures 1-12 The stranding equipment and its processing technology for high-strength steel wire rope processing for cranes include a workbench 3, a horizontal cylinder 12, and a winding wheel 1. The top of the workbench 3 is bolted to a left support frame 4, and the top of the left support frame 4 is pivotally connected to the horizontal cylinder 12. A twisting gear 15 is fixedly welded to one end of the horizontal cylinder 12, and a drawing disc 13 is fixedly welded to one side of the twisting gear 15. The twisting gear 15 and the drawing disc 13 are concentrically arranged. The side of the drawing disc 13 has a circular array of raw material steel wire release components, which simultaneously release multiple strands of raw material steel wire.

[0034] The raw material steel wire release assembly includes a feeding frame 17, a storage wheel 18, and a guide wheel 191. One end of the feeding frame 17 is fixedly connected to the end face of the drawing plate 13 by bolts. A horizontal column 181 is rotatably connected to the top of one end of the feeding frame 17. A through hole with the same diameter as the horizontal column 181 is opened at the top of the feeding frame 17. The horizontal column 181 is movably inserted into the through hole and movably inserted into the center position of the storage wheel 18. Locking bolts 1810 are screwed into both ends of the horizontal column 181. The two locking bolts 1810 can ensure that the horizontal column 181 is fixed to the top of the feeding frame 17. In order to facilitate the operator to directly turn the locking bolts 1810 by hand, a rotating arm is welded to the outer wall of the locking bolt 1810.

[0035] A certain amount of raw material steel wire is wound around the outer wall of the storage wheel 18. When the storage wheel 18 has finished releasing the raw material steel wire, the locking bolts 1810 at both ends of the horizontal column 181 can be unscrewed, and the horizontal column 181 can be pulled out from the corresponding through hole on the feeding frame 17. The old storage wheel 18 can be removed from the feeding frame 17 and replaced with a new storage wheel 18 to complete the replenishment of raw material steel wire. The feeding frame 17 is fixedly welded with support rods 19 at equal intervals on one side of the storage wheel 18. The top of the support rods 19 is rotatably connected to the guide wheel 191 by a pin. There are two guide wheels 191 on the same feeding rack 17. The drawing plate 13 has a drawing hole 131 on one side of the guide wheel 191. The central axis of the two guide wheels 191 is the same distance from the end face of the feeding rack 17. The guide wheel 191 guides the raw material steel wire released from the outer wall of the storage wheel 18 to the drawing hole 131. The diameter of the drawing hole 131 is smaller than the diameter of the raw material steel wire. When the entire twisting equipment is used for threading, it is necessary to use pliers to force one end of the raw material steel wire through the drawing hole 131.

[0036] The side of the twisting gear 15 has a circular array of rectangular grooves 151. The worktable 3 is provided with a drawing and twisting integrated assembly on one side of the twisting gear 15, which draws multiple strands of raw steel wire into a specified diameter and twists them into a single strand of steel wire rope. The drawing and twisting integrated assembly includes a gathering cylinder 320, a guide cone cylinder 16, a twisting motor 11, and a lower drive gear 110. The twisting motor 11 is bolted to the bottom of the worktable 3. The output end of the twisting motor 11 is fixedly connected to the lower drive gear 110 by a coupling. The lower drive gear 110 meshes stably with the twisting gear 15. The worktable 3 has a middle groove 31 above the twisting gear 15. A part of the top of the lower drive gear 110 meshes with the twisting gear 15 from the middle groove 31. In order to make the twisting gear 15 rotate slowly to perform the twisting action, the number of teeth of the lower drive gear 110 is less than the number of teeth of the twisting gear 15.

[0037] The guide cone 16 is fixedly welded to one end of the horizontal cylinder 12. The guide cone 16 is connected to the horizontal cylinder 12. The guide cone 16 is a cone-shaped cylinder. The opening of the guide cone 16 gradually decreases in size at the end away from the left support 4. The central iron core of the wire rope passes through the horizontal cylinder 12, through the twisting gear 15, and finally out of the guide cone 16 and into the gathering cylinder 320. The bottom of the gathering cylinder 320 is fixedly welded with a suspension seat 32. The suspension seat 32 is fixedly connected to the top of the workbench 3 with bolts. The raw material wires emitted from the outer wall of the multiple feeding wheels 18 pass through the drawing hole 131 and the twisting gear 15 and then gather with the central iron core in the gathering cylinder 320.

[0038] Twisting and gathering is the process of twisting multiple steel wires together into a strand according to a predetermined twist pitch and direction. The multiple strands of raw steel wires will generate intense friction within the gathering cylinder 320. Introducing lubricating oil can form an oil film on the contact surface, reducing the coefficient of friction and preventing scratches, burrs, or deformation on the wire surface. Therefore, refer to... Figure 3 An oil inlet pipe is connected to the top of the gathering cylinder 320, and an electric lubrication pump station is connected to the oil inlet pipe to continuously introduce lubricating oil into the inner cavity of the gathering cylinder 320.

[0039] The workbench 3 is bolted to a right support frame 2 at the end away from the horizontal cylinder 12. A take-up wheel 1 is rotatably connected to the right support frame 2 by a pin. A belt drive assembly is provided at one end of the shaft of the take-up wheel 1. The belt drive assembly drives the take-up wheel 1 to rotate, continuously winding and pulling the single strand of steel wire rope twisted by the twisting assembly. The belt drive assembly includes a driven pulley 10, a driving pulley 8, a take-up motor 9, a tensioning wheel 5, and an electric push rod 6. The take-up motor 9 is bolted to the side of the fixing plate 33. The fixing plate 33 is welded to the bottom of the workbench 3. The output end of the take-up motor 9 is fixedly connected to the driving pulley 8 by a coupling.

[0040] Driven pulley 10 is concentrically fixed to the shaft of take-up reel 1. An edge groove is provided at the top edge of the worktable 3. An electric push rod 6 is bolted to the side of the edge groove. A fixed seat 61 is bolted to the output end of the electric push rod 6. (Reference) Figure 3 The fixing seat 61 is made of two vertical plates welded perpendicularly to each other. It is L-shaped when viewed from above. The side of the fixing seat 61 is rotatably connected to the tensioning wheel 5 by a pin. The tensioning wheel 5, the driven pulley 10, and the driving pulley 8 are all fitted with a common belt 7 on their outer walls. The tensioning wheel 5, the driven pulley 10, and the driving pulley 8 are of the same thickness, and an annular belt groove is opened on the outer wall to accommodate the common belt 7.

[0041] When the electric push rod 6 extends, the common belt 7 is tightened by the tensioning pulley 5, the driven pulley 10, and the driving pulley 8. In order to prevent the common belt 7 from disengaging from the grooves of the driving pulley 8 and the driven pulley 10 when the electric push rod 6 retracts, the extension stroke of the electric push rod 6 is set to be relatively short. Finally, in order to achieve the slow rotation of the winding wheel 1, the diameter of the driving pulley 8 is smaller than the diameter of the driven pulley 10.

[0042] A tension-sensing wire breakage stop assembly is installed in the rectangular groove 151 to capture the pulling and twisting tension of multiple raw material steel wires. When any raw material steel wire breaks during pulling and twisting, the belt drive assembly is controlled to stop driving the winding wheel 1 to rotate. The tension-sensing wire breakage stop assembly includes a fixed frame 23, a guide plate 25, a trigger post 26, a common ring 14, and a micro switch 28. The fixed frame 23 is symmetrically connected to the transmission wheels 24 by pins. The gap between the two transmission wheels 24 is equal to the diameter of a single raw material steel wire. After the raw material steel wire passes through the pulling hole 131 of the drawing plate 13, it needs to pass through the gap between the two transmission wheels 24.

[0043] A guide post 22 is fixedly welded to one end of the fixed frame 23. A retaining spring 21 is sleeved on the outer wall of the guide post 22. The other end of the retaining spring 21 is sleeved on the outer wall of the fixed post 20. The fixed post 20 is fixedly welded to the side of the rectangular groove 151. The fixed frame 23 is the same width as the rectangular groove 151. When installing the fixed frame 23 into the rectangular groove 151, the worker first uses a tool to squeeze the retaining spring 21 to the extreme compression position, sleeves one end of the retaining spring 21 on the outer wall of the fixed post 20, and then inserts the fixed frame 23 into the rectangular groove 151. The retaining spring 21 is released, and the other end of the retaining spring 21 is sleeved on the guide post 22. At this time, one end of the fixed frame 23 is attached to the side of the rectangular groove 151, and the retaining spring 21 has a certain amount of pre-compression.

[0044] The twisting gear 15 has an insertion slot 152 on one side of the rectangular groove 151. A guide plate 25 is bolted to the end of the fixing frame 23 away from the guide post 22. The guide plate 25 is movably inserted into the insertion slot 152. The guide plate 25 and the insertion slot 152 are of the same width. A zigzag groove 251 is formed on the guide plate 25, into which a drive post 261 is movably inserted. A trigger post 26 is bolted to one end of the drive post 261. The trigger post 26 is movably inserted into the twisting gear 15. Multiple trigger posts 26 extend from the end face of the twisting gear 15. (Reference) Figure 11 The zigzag groove 251 includes two horizontal sections and an inclined section connecting the two horizontal sections. When the tension of the raw material steel wire suddenly increases, it forces the fixed frame 23 to compress the retaining spring 21. The drive column 261 moves relative to the zigzag groove 251, which will drive the trigger column 26 to extend from the end face of the twisting gear 15 and generate a hard impact with the common ring 14. The head of the trigger column 26 is bonded with a rubber column with a diameter larger than that of the trigger column 26.

[0045] A common ring 14 is set in the gap between the drawing plate 13 and the twisting gear 15, and is concentrically set with the drawing plate 13 and the twisting gear 15. An application column 27 is fixedly welded to the side of the common ring 14. The side of the application column 27 is fixedly connected to one end of the retaining spring 29. The other end of the retaining spring 29 is fixedly connected to the side of the intermediate seat 30. The bottom of the intermediate seat 30 is fixedly connected to the worktable 3 with bolts. The application column 27 is movably inserted into the intermediate seat 30. A micro switch 28 is fixedly connected to one end of the application column 27 with bolts. The micro switch 28 is electrically connected to the electric push rod 6. The micro switch 28 and the electric push rod 6 are connected to the same PLC controller in the prior art. When the micro switch 28 is triggered, the electric push rod 6 will retract under the control of the PLC controller.

[0046] The specific implementation steps and principles of this invention are as follows: In the initial state, a certain amount of raw material steel wire is wound on multiple storage wheels 18, and the retaining spring 21 is under a certain compression. The retaining spring 21 forces the fixed frame 23 to fit against the rectangular groove 151 at one end near the guide plate 25. Figure 11 The drive column 261 is located in the zigzag groove 251 and is located on the side close to the fixed frame 23. At this time, multiple trigger columns 26 are retracted into the inner cavity of the twisting gear 15, keeping the spring 29 at its original length. Multiple trigger columns 26 do not press the common ring 14, and the application column 27 does not press onto the micro switch 28. At this time, the electric push rod 6 extends normally and tightens the common belt 7 through the tensioning wheel 5.

[0047] The worker uses pliers to hold and pass one end of multiple raw material steel wires through the gap between the support rod 19 and the guide wheel 191, then forces them through the drawing hole 131 of the drawing plate 13, and then through the two transfer wheels 24 of a fixed frame 23. Finally, they extend out from the narrow end of the gathering cylinder 320. The iron core wire passes through the horizontal cylinder 12 and the guide cone cylinder 16 in sequence, fixing one end of the multiple raw material steel wires and one end of the iron core to the outer wall of the winding wheel 1. The winding motor 9 and the twisting motor 11 are started. On the one hand, the winding motor 9 drives the driven pulley 10 to rotate through the driving pulley 8, the common belt 7, and the tensioning wheel 5, thereby driving the winding wheel 1 to rotate and pull and wind multiple raw material steel wires and the iron core wire. On the other hand, the twisting motor 11 drives the twisting gear 15 to rotate through the lower drive gear 110, causing multiple raw material steel wires to twist on the outer wall of the iron core wire.

[0048] When any of the raw material steel wires exceeds the preset tension, the fixed frame 23 is forced to compress the retaining spring 21 through the transmission wheel 24. One side of the fixed frame 23 is separated from the side of the rectangular groove 151, and at the same time, the guide plate 25 is moved. The drive column 261 moves from one end of the zigzag groove 251 to the other end. The drive column 261 drives the trigger column 26 to extend out of the inner cavity of the twisting gear 15. The trigger column 26 presses against the common ring 14 and moves laterally. The common ring 14 drives the application column 27 to trigger the micro switch 28. At this time, the electric push rod 6 receives a signal to drive the tensioning wheel 5 to retract. At this time, the common belt 7 is no longer taut, the winding wheel 1 stops rotating, and the winding wheel 1 stops pulling and winding multiple raw material steel wires and iron core wires.

[0049] 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.
