Description

Technical Field

[0001] This utility model relates to the field of wire rope double twisting technology, and in particular to a tension-adjustable wire rope double twisting machine. Background Technology

[0002] Double twisting of wire rope is a processing method that produces high-strength and highly flexible wire rope through two twisting processes. This process can significantly improve the structural stability and fatigue resistance of wire rope and is widely used in hoisting, shipbuilding, mining and other fields.

[0003] Current double twisting machines typically have guide wheels on the table to guide the direction of the wire rope during the twisting process. These guide wheels constrain the path of the wire rope, ensuring that it maintains a certain tension when passing through the twisting device, thus preventing uneven strand arrangement or wire skipping caused by slack.

[0004] However, while guide wheels can provide basic tension for wire ropes, their adjustment capability is limited. The ideal tension required for wire ropes of different diameters, materials, and structures varies, and traditional guide wheels can usually only provide fixed or limited tension adjustment. This uniform tension is difficult to meet the process requirements of diverse products and may lead to excessive tension (damaging the wire surface) or excessive looseness (incomplete twisting), affecting the performance and production efficiency of the wire rope. Therefore, a tension-adjustable wire rope double twisting machine is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a tension-adjustable wire rope double twisting machine, which aims to solve the problem mentioned in the prior art that "current double twisting machines cannot flexibly adjust the wire tension when dealing with wires of different diameters".

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a tension-adjustable wire rope double twisting machine, including a base plate, a double twisting assembly fixedly installed on the top of the base plate, an adjustment platform fixedly installed on the top of the base plate, and a tensioning mechanism and a cleaning mechanism provided inside the adjustment platform;

[0007] The tensioning mechanism includes a fixed rod, with sliders fixedly installed at both ends of the fixed rod. A guide wheel is rotatably connected to the outer wall of the fixed rod, and a groove is provided on the guide wheel. A rotating shaft is rotatably connected through the side wall of the adjusting platform. A worm gear is fixedly installed at one end of the rotating shaft, and a hollow rod is fixedly installed at the other end of the rotating shaft. A sliding shaft is fixedly installed on the side wall of the slider at the right end of the fixed rod. A worm gear is rotatably connected through the top of the adjusting platform, and a knob is fixedly installed on the top of the worm gear.

[0014] As a further description of the above technical solution:

[0015] A rubber pad is fixedly installed on the inner wall of the groove.

[0016] As a further description of the above technical solution:

[0018] As a further description of the above technical solution:

[0019] The outer wall of the sliding shaft is attached to the inner wall of the hollow rod, and the slider is slidably connected to the inner wall of the adjusting table.

[0020] As a further description of the above technical solution:

[0021] The fixing rod is provided in two sets, and the two sets of fixing rods are mirror images of each other inside the adjustment table with the rotating shaft as the central axis.

[0024] 2.

Detailed Implementation

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-3 One embodiment of this utility model is a tension-adjustable wire rope double twisting machine, which includes a base plate 1, a double twisting assembly 2 fixedly installed on the top of the base plate 1, an adjustment platform 3 fixedly installed on the top of the base plate 1, and a tensioning mechanism 4 and a cleaning mechanism 5 arranged inside the adjustment platform 3.

[0032] Reference Figures 2-3The tensioning mechanism 4 includes a fixed rod 41, with sliders 42 fixedly installed at both ends of the fixed rod 41. The distance between the two sets of fixed rods 41 can be adjusted by sliding the sliders 42. The sliders 42 are slidably connected to the inner wall of the adjusting platform 3. When the hollow rod 47 pushes the sliding shaft 48, the sliding shaft 48 pushes the sliders 42, causing the sliders 42 to slide on the inner wall of the adjusting platform 3. Two sets of fixed rods 41 are provided, mirror-imagely arranged inside the adjusting platform 3 with the rotating shaft 45 as the central axis. The outer wall of the fixed rod 41 is rotatably connected to a guide wheel 43. The guide wheel 43 can not only guide the wire rope but also adjust the tension of the wire rope. The guide wheel 43 has a groove 44, which can axially limit the wire rope. The side wall of the adjusting platform 3 is rotatably connected to the rotating shaft 45, and a worm gear 4 is fixedly installed at one end of the rotating shaft 45. 6. A hollow rod 47 is fixedly installed at the other end of the rotating shaft 45. When the rotating shaft 45 rotates, it will drive the hollow rod 47 to rotate synchronously. A sliding shaft 48 is fixedly installed on the side wall of the slider 42 at the right end of the fixed rod 41. The outer wall of the sliding shaft 48 is attached to the inner wall of the hollow rod 47. When the hollow rod 47 rotates, it will push the sliding shaft 48, causing the sliding shaft 48 to move on the inner wall of the hollow rod 47. A worm gear 49 is rotatably connected through the top of the adjusting platform 3. The worm gear 49 meshes with the worm wheel 46. When the worm gear 49 rotates, it can drive the rotating shaft 45 to rotate on the inner wall of the adjusting platform 3 in conjunction with the worm wheel 46. A knob 410 is fixedly installed on the top of the worm gear 49. The worm gear 49 can be easily rotated by the knob 410. A rubber pad 411 is fixedly installed on the inner wall of the groove 44. The rubber pad 411 can protect the wire rope and prevent the guide wheel 43 from wearing the wire rope.

[0033] Reference Figures 2-3 The cleaning mechanism 5 includes an L-plate 51, which is fixedly installed on the outer wall of the fixed rod 41. A rotating drum 52 is rotatably connected through the inner wall of the L-plate 51. The L-plate 51 provides support for the rotating drum 52. Brush bristles 53 are fixedly installed on the inner wall of the rotating drum 52. The rotation of the rotating drum 52, in conjunction with the brush bristles 53 on its inner wall, can clean the surface of the wire rope and prevent impurities from affecting the double twist effect of the wire rope. A driven bevel gear 54 is fixedly installed at one end of the rotating drum 52 near the fixed rod 41. A drive bevel gear 55 is fixedly installed on the outer wall of the guide wheel 43. The drive bevel gear 55 meshes with the driven bevel gear 54. When the guide wheel 43 rotates, it can drive the rotating drum 52 to rotate synchronously on the inner wall of the L-plate 51 in conjunction with the drive bevel gear 55 and the driven bevel gear 54.

[0034] Working principle: When in use, the two steel wire ropes are passed through the inside of the two sets of rotating drums 52 and placed in the grooves 44 of the two sets of guide wheels 43 respectively, so that the two steel wire ropes form an "S" shape on the two sets of fixed rods 41. Then, the two steel wire ropes are guided into the inside of the double twist assembly 2, and the two steel wire ropes are twisted together by the double twist assembly 2.

[0035] Rotating the worm gear 49 via knob 410 causes the meshing worm wheel 46 to rotate. The worm wheel 46 then drives the rotating shaft 45 to rotate on the inner wall of the adjusting platform 3. Simultaneously, the rotating shaft 45 drives the hollow rod 47 to rotate synchronously. The hollow rod 47, in turn, pushes the sliding shaft 48, causing it to move along its inner wall. Simultaneously, the sliding shaft 48 pushes the slider 42, causing it to slide along the inner wall of the adjusting platform 3. Meanwhile, the right ends of the two sets of fixed rods 41... The slider 42 moves in opposite directions on the inner wall of the adjusting platform 3, thereby causing the two sets of fixed rods 41 to move synchronously in opposite directions. This allows for adjustment of the distance between the guide wheels 43 on the two sets of fixed rods 41. As the guide wheels 43 move further apart, the tension applied to the wire rope by the guide wheels 43 gradually increases. As the guide wheels 43 move closer together, the tension applied to the wire rope by the guide wheels 43 gradually decreases. This allows for free adjustment of the tension on the wire rope according to different diameters, improving the practicality of the equipment.

[0036] When the guide wheel 43 guides the wire rope, the rubber pad 411 protects the wire rope and prevents the guide wheel 43 from causing wear. At the same time, the friction of the rubber pad 411 causes the wire rope to rotate on the outer wall of the fixed rod 41 as it passes through the guide wheel 43. The rotation of the guide wheel 43 drives the drive bevel gear 55 to rotate synchronously. The rotation of the drive bevel gear 55 drives the driven bevel gear 54, which meshes with it, to rotate synchronously. At this time, the driven bevel gear 54 drives the rotating drum 52 to rotate synchronously on the inner wall of the L plate 51. As the rotating drum 52 rotates, the bristles 53 on its inner wall move against the outer wall of the wire rope. The bristles 53 can clean the surface of the wire rope and prevent metal debris from adhering to the surface of the wire rope and affecting its double twist effect.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
