Description

Technical Field

[0001] This utility model relates to the field of steel wire rope surface treatment technology, specifically to a floating polishing device that can adapt to changes in steel wire rope diameter and surface undulations. Background Technology

[0002] Existing wire rope polishing devices mostly use rigidly mounted or threaded fine-tuning polishing wheels, which have significant limitations: First, for wire ropes with slight bends or uneven diameters, rigid contact leads to unstable polishing pressure, sometimes resulting in over-polishing (wearing down the wire rope) and sometimes insufficient polishing. Second, when changing to wire ropes of different specifications, the position of each polishing wheel needs to be readjusted, which is time-consuming and labor-intensive. In addition, the traditional circumferential staggered arrangement places high demands on the layout of the polishing wheels and lacks structural flexibility.

[0003] Therefore, a new type of polishing device is needed that can automatically adapt to the condition of the wire rope, maintain constant polishing pressure, and has a high degree of modularity. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a steel wire rope polishing device that features adaptive polishing pressure, high stability, and strong versatility.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a wire rope polishing device, comprising a frame, a wire feeding mechanism, a wire take-up mechanism, and a polishing mechanism. Its innovation lies in: the polishing mechanism includes a polishing chamber, within which at least two adaptive polishing modules are arranged circumferentially around the wire rope; the adaptive polishing module includes: The module mounting base is fixed to the wall of the polishing chamber; The pressure generator is hinged at one end to the polishing chamber wall. The swing arm has one end hinged to the module mounting base via a hinge shaft; A drive motor and a polishing wheel are provided, wherein the drive motor is mounted on the free end of the swing arm and is used to drive the polishing wheel to rotate; The output of the pressure generator acts on the swing arm to provide a constant preload force that presses the polishing wheel against the wire rope.

[0006] Furthermore, the pressure generator is a cylinder, a hydraulic cylinder, or a constant force spring device.

[0007] Furthermore, a torsion spring is provided at the hinge point between the swing arm and the module mounting base to provide clamping force to the swing arm.

[0008] Furthermore, the outer edge contour of the polishing wheel is a concave V-shape or arc shape.

[0009] Furthermore, the polishing chamber is equipped with an openable sealed door at the top and a waste collection port at the bottom.

[0010] Furthermore, the number of adaptive polishing modules is three, and they are evenly distributed around the steel wire rope at a 120° angle.

[0011] The beneficial effects of this utility model after adopting the above structure are as follows: Adaptive polishing: Through a unique design of "swing arm + pressure generator (such as a cylinder)," the polishing wheel becomes a floating body. When the diameter of the steel wire rope changes or there is a slight jump, the swing arm can swing accordingly, and the pressure generator can instantly compensate for the displacement, maintaining a constant pressure of the polishing wheel on the surface of the steel wire rope, thereby obtaining an extremely uniform polished surface quality and effectively avoiding over-polishing damage.

[0012] Exceptional versatility and ease of use: When changing to wire ropes of different diameters, no manual adjustment of the polishing wheel is required. The system automatically adapts to diameter changes, greatly reducing operational difficulty and processing time.

[0013] Modular design and high stability: Each adaptive polishing module is an independent functional unit, making maintenance and replacement convenient. Multiple modules are arranged in a ring to form a stable "multi-point cohesion" polishing structure, effectively suppressing vibration and deviation of the wire rope during the polishing process.

[0014] Environmentally friendly and clean: The enclosed polishing chamber design confines polishing dust within a limited space, facilitating centralized collection and treatment, improving the working environment, and meeting the requirements of modern clean production.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model.

[0019] like Figure 1As shown, the wire rope polishing device of this embodiment includes a frame 1, a wire feeding mechanism, a wire take-up mechanism, and a polishing mechanism 2.

[0020] The polishing mechanism 2 is equipped with a cylindrical polishing chamber 21. The top of the polishing chamber 21 is equipped with an openable and closable sealed door 211 for threading steel wire ropes and inspecting internal modules; the bottom is equipped with a funnel-shaped waste collection port 212, which can be connected to a dust removal pipe or a dust collection bag. The polishing chamber 21 has an inlet and an outlet for the entry and exit of steel wire.

[0021] Inside the polishing chamber 21, three adaptive polishing modules 3 are uniformly fixed along the circumference. Each module includes: a module mounting base 31 welded to the chamber wall, a cylinder 32 (pressure generator) mounted on the chamber wall via a hinge bracket, a freely swinging arm 33 connected to the module mounting base 31 via a hinge shaft 34, and a drive motor (not shown) and a V-shaped polishing wheel 35 mounted at the end of the swing arm 33. The piston rod of the cylinder 32 rests against the middle of the swing arm 33.

[0022] Working Process: First, based on the material of the steel wire rope to be polished and the required polishing intensity, adjust the intake pressure of all cylinders 32 to set a uniform and appropriate polishing preload. Then, pass the steel wire rope through the center of the polishing chamber. After starting the equipment, the take-up mechanism pulls the steel wire rope forward at a uniform speed, while all drive motors start, driving the V-shaped polishing wheels 35 to rotate at high speed. Under the thrust of the cylinders 32, the three polishing wheels 35 press evenly against the surface of the steel wire rope from three directions. When the steel wire rope has uneven diameter or slight bending, the three swing arms 33 will swing slightly in coordination, and the piston rod of the cylinders 32 will extend and retract accordingly, always maintaining stable pressure. The three V-shaped wheels work together to perform all-round, constant-pressure precision polishing of the steel wire rope.

[0023] Since the three polishing wheels have equal forces (achieved through uniform pressure adjustment) and are 120° apart, they cancel each other out at the center of the wire rope, resulting in zero radial force on the wire rope.

[0024] During the polishing process, the wire rope is in a stable mechanical equilibrium state and will not be pushed away from the center line due to unilateral or asymmetrical polishing pressure, effectively preventing deviation and vibration.

[0025] Three points can define a circle. Three polishing wheels work simultaneously from three directions, and their polishing areas (especially when using V-shaped or arc-shaped wheels) can seamlessly cover the entire circumference of the wire rope.

[0026] As the wire rope moves in a straight line, it usually has a slight twist, which ensures that even the smallest areas that are not directly covered can be polished during the journey.

[0027] Because of the balanced force, the polishing pressure and number of polishing cycles are equal at all points on the surface of the wire rope, avoiding the problems of excessive wear on the top and bottom surfaces and insufficient wear on the sides that may occur with the traditional top-bottom arrangement.

[0028] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
