AI Technical Summary
The stranding equipment for high-strength steel wire rope processing for cranes has problems such as separation of the drawing and stranding processes and low equipment integration, which leads to increased production time and damage to the surface of the steel wire. In addition, the lack of real-time tension monitoring makes it easy for multiple strands of steel wire to become entangled when a single raw material steel wire breaks, resulting in product scrap.
An integrated drawing and twisting device was designed, including a worktable, a horizontal drum, a winding wheel, and a tension-sensing wire breakage stop assembly. By simultaneously releasing multiple strands of raw steel wire and monitoring the tension in real time, the device can automatically stop the twisting process, thus avoiding damage and tangling of the steel wire rope.
It improves production efficiency, reduces surface damage to steel wire, lowers product scrap rate, and ensures the safety and continuity of the processing.

TECHNICAL FIELD
[0001] The present application relates to the technical field of steel wire rope drawing and stranding, in particular to a stranding device for processing high-strength steel wire rope for cranes and a processing technology thereof. BACKGROUND
[0002] The core of the stranding machine process for processing high-strength steel wire rope for cranes is to spiral wrap multiple steel wires into strands according to a specific twisting direction and pitch, so as to give the steel wire rope basic structural strength and flexibility. A single steel wire is rigid and easy to break, and after stranding, a stress dispersion structure is formed between the steel wires, which can withstand the tensile and bending load during the lifting and amplitude change of the crane, while improving the anti-torsion and anti-fatigue performance, avoiding single wire stress fracture, laying a foundation for the subsequent rope combining process, and ensuring that the steel wire rope meets the heavy load operation requirements of the crane.
[0003] At present, the stranding device for processing high-strength steel wire rope for cranes generally has the defects of separation of drawing and stranding processes and low equipment integration. The raw steel wire needs to be drawn into a specified diameter by a drawing device first, and then transferred to a stranding device for stranding. The multi-process transfer not only increases the production time, but also easily causes damage to the surface of the steel wire. At the same time, the traditional equipment lacks real-time tension monitoring to realize the anti-breaking wire self-stop function, and the broken single raw steel wire is easy to cause multiple steel wire winding and product scrap.

Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0033] Reference Figures 1-12 The twisting device for processing high-strength steel wire rope for cranes and the processing technology thereof, comprising a workbench 3, a horizontal cylinder 12 and a winding wheel 1, the top of the workbench 3 is fixedly connected with a left support frame 4 through bolts, the top of the left support frame 4 is rotationally connected with the horizontal cylinder 12 through a pin shaft, one end of the horizontal cylinder 12 is fixedly welded with a twisting gear 15, the horizontal cylinder 12 is fixedly welded with a drawing disc 13 on the side of the twisting gear 15, the twisting gear 15 and the drawing disc 13 are concentrically arranged, and the drawing disc 13 has a plurality of raw material steel wire release assemblies arranged in a circular array on the side, which synchronously release a plurality of raw material steel wires.
[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 disc 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 formed in the top end of the feeding frame 17. The horizontal column 181 is movably inserted into the center 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 rotate the locking bolt 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 releases the raw material steel wire, the locking bolts 1810 at both ends of the horizontal column 181 can be unscrewed. The horizontal column 181 is pulled out of the corresponding through hole in the feeding frame 17. The old storage wheel 18 is removed from the feeding frame 17, and a new storage wheel 18 is replaced. The raw material steel wire is replenished. The feeding frame 17 is fixedly welded with a support rod 19 equidistantly on one side of the storage wheel 18. The support rod 19 is rotatably connected with a guide wheel 191 at the top by a pin shaft. There are two guide wheels 191 on the same feeding frame 17. The drawing disc 13 is provided with a drawing hole 131 on one side of the guide wheel 191. The center axes of the two guide wheels 191 are equidistant from the end face of the feeding frame 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 that of the raw material steel wire. During the threading work of the stranding device, a pliers tool is used to forcibly pull one end of the raw material steel wire through the drawing hole 131.
[0036] The side surface of the twisting gear 15 is circularly arrayed with rectangular grooves 151. The workbench 3 is provided with a drawing and stranding integrated assembly on one side of the twisting gear 15. The drawing and stranding 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 fixedly connected to the bottom of the workbench 3 by bolts. The output end of the twisting motor 11 is fixedly connected with the lower drive gear 110 by a shaft coupling. The lower drive gear 110 is stably engaged with the twisting gear 15. The workbench 3 is provided with an intermediate groove 31 above the twisting gear 15. A part of the top of the lower drive gear 110 will engage with the twisting gear 15 from behind the intermediate groove 31. In order to make the twisting gear 15 rotate slowly for stranding, the number of teeth of the lower drive gear 110 is less than that of the twisting gear 15.
[0037] The guide cone 16 is fixedly welded at one end of the horizontal cylinder 12, the guide cone 16 communicates with the horizontal cylinder 12, the guide cone 16 is a tapered cylinder in appearance, the opening at the end away from the left support frame 4 of the guide cone 16 gradually decreases, the center iron core of the steel wire rope passes through the horizontal cylinder 12, passes through the twisting gear 15, and finally passes out of the guide cone 16 and enters 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 by bolts, and the raw material steel wire emitted from the outer wall of the plurality of feeding wheels 18 passes through the drawing hole 131, the twisting gear 15, and is gathered in the gathering cylinder 320 together with the center iron core.
[0038] The twisting and gathering is a process of twisting a plurality of steel wires into a strand rope according to a predetermined twist pitch and twist direction. The plurality of raw material steel wires will generate intense friction in the gathering cylinder 320. The introduction of lubricating oil can form an oil film on the contact surface, reduce the friction coefficient, and avoid scratches, fuzz or deformation on the surface of the steel wire. Therefore, according to the reference Figure 3 , an oil inlet pipe is connected to the top of the gathering cylinder 320, and an electric lubricating pump station is connected to the outside of the oil inlet pipe to continuously introduce lubricating oil into the inner cavity of the gathering cylinder 320.
[0039] The workbench 3 is fixedly connected to the right support frame 2 at the end away from the horizontal cylinder 12 by bolts, and the winding wheel 1 is rotatably connected to the right support frame 2 by a pin shaft. The winding wheel 1 is provided with a belt driving assembly at one end of the rotating shaft. The belt driving assembly drives the winding wheel 1 to rotate, continuously winding the single steel wire rope twisted by the drawing and twisting integrated assembly. The belt driving assembly includes a driven pulley 10, a driving pulley 8, a winding motor 9, a tensioning wheel 5, and an electric push rod 6. The winding motor 9 is fixedly connected to the side of the fixed plate 33 by bolts. The fixed plate 33 is welded below the workbench 3. The output end of the winding motor 9 is fixedly connected to the driving pulley 8 by a shaft coupling.
[0040] The driven pulley 10 is fixedly connected to the rotating shaft of the winding wheel 1 in a concentric manner. An edge groove 33 is formed at the edge of the top of the workbench 3. The electric push rod 6 is fixedly connected to the side of the edge groove 33 by bolts. The output end of the electric push rod 6 is fixedly connected to a fixed seat 61 by bolts. According to the reference Figure 3 , the fixed seat 61 is formed by welding two vertical plates perpendicular to each other, and is L-shaped when viewed from the top. The fixed seat 61 is rotatably connected to the tensioning wheel 5 by a pin shaft. The tensioning wheel 5, the driven pulley 10, and the driving pulley 8 are commonly sleeved with a common belt 7. The thicknesses of the tensioning wheel 5, the driven pulley 10, and the driving pulley 8 are the same, and the outer walls of the tensioning wheel 5, the driven pulley 10, and the driving pulley 8 are provided with annular belt grooves for accommodating the common belt 7.
[0041] When the electric push rod 6 is extended, the common belt 7 is tautened by the tensioning wheel 5, the driven pulley 10 and the driving pulley 8, so that the common belt 7 is not taut when the electric push rod 6 is retracted, and the common belt 7 does not come off the wheel groove of the driving pulley 8 and the driven pulley 10. The extension stroke of the electric push rod 6 is set to be short. Finally, in order to achieve the slow rotation of the winding wheel 1, the diameter of the driving pulley 8 is smaller than that of the driven pulley 10.
[0042] A tension sensing broken wire stop component is arranged in the rectangular groove 151 to capture the drawing and twisting tension of the plurality of raw steel wires. When any one of the raw steel wires is broken during drawing and twisting, the control belt driving component stops driving the winding wheel 1 to rotate. The tension sensing broken wire stop component comprises a fixed frame 23, a guide plate 25, a trigger column 26, a common ring 14 and a micro switch 28. The fixed frame 23 is symmetrically connected with transmission wheels 24 by pin shafts. The gap between the two transmission wheels 24 is equal to the diameter of a single raw steel wire. The raw steel wire needs to pass through the gap between the two transmission wheels 24 after passing through the drawing hole 131 of the drawing disc 13.
[0043] One end of the fixed frame 23 is fixedly welded with a guide column 22. The guide column 22 is sleeved with a resisting spring 21. The other end of the resisting spring 21 is sleeved on the outer wall of a fixed column 20. The fixed column 20 is fixedly welded on the side of the rectangular groove 151. The fixed frame 23 is equal in width to the rectangular groove 151. When the fixed frame 23 is installed in the rectangular groove 151, the worker first pinches the resisting spring 21 to the limit compression position by using a tool, and then sleeves one end of the resisting spring 21 on the outer wall of the fixed column 20. Then the fixed frame 23 is inserted into the rectangular groove 151. The resisting spring 21 is loosened, and the other end of the resisting spring 21 is sleeved on the guide column 22. At this time, one end of the fixed frame 23 is attached to the side of the rectangular groove 151. The resisting spring 21 has a certain pre-compression amount at this time.
[0044] The twisting gear 15 is provided with an insertion groove 152 on one side of the rectangular groove 151. The end of the fixed frame 23 away from the guide column 22 is fixedly connected with a guide plate 25 by bolts. The guide plate 25 is movably inserted into the insertion groove 152. The guide plate 25 is equal in width to the insertion groove 152. The guide plate 25 is provided with a zigzag groove 251. The zigzag groove 251 movably inserts a driving column 261. One end of the driving column 261 is fixedly connected with the trigger column 26 by bolts. The trigger column 26 is movably inserted into the twisting gear 15. A plurality of trigger columns 26 extend from the end surface of the twisting gear 15. Referring to Figure 11 The zigzag groove 251 comprises two horizontal sections and an inclined section connecting the two horizontal sections. When the raw steel wire tension suddenly increases and forces the fixed frame 23 to compress the resisting spring 21, the driving column 261 moves relative to the zigzag groove 251, which drives the trigger column 26 to extend from the end surface of the twisting gear 15 and 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 one of the raw steel wires exceeds the preset tension, the fixed frame 23 is forced to compress against the 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 the guide plate 25 is moved at the same time, the driving column 261 is moved from one end to the other end of the zigzag groove 251, the driving column 261 drives the trigger column 26 to extend out of the inner cavity of the twisting gear 15, the trigger column 26 is pressed to the horizontal movement of the common ring 14, the common ring 14 drives the application column 27 to trigger the micro switch 28, at this time the electric push rod 6 obtains a signal to drive the tensioning wheel 5 to retract, at this time the common belt 7 is no longer tightened, the winding wheel 1 stops rotating, and the winding wheel 1 stops pulling the wound raw steel wires and the core wire.
[0049] The above merely describes the preferred embodiments of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered by the protection scope of the present application.
