Description

Technical Field

[0001] This invention belongs to the field of wire rope winding technology, specifically referring to a wire rope winding device. Background Technology

[0002] In industrial production, wire rope serves as a crucial load-bearing and traction component, and the performance of its winding device directly impacts operational efficiency and safety. Traditional wire rope winding devices suffer from the following significant shortcomings in practical applications:

[0003] (1) Existing devices mostly adopt a unified drive mode, which cannot realize independent start and stop control of a single winding drum. When multiple winding drums are working at the same time, if a winding drum completes the winding task, it is necessary to stop the machine and manually brake it, which will force other winding drums to stop, seriously affecting the overall work efficiency.

[0004] (2) Tension fluctuation is a common problem during the wire rope winding process. When the tension suddenly increases, it is easy to cause a rope breakage accident, while when the tension is too low, it will cause the winding to become loose. Summary of the Invention

[0005] This invention overcomes the shortcomings of existing technologies and provides a wire rope take-up device. By utilizing the mechanical balance between the wire rope's own tension and the return spring, the take-up drum automatically unlocks when tension is present and automatically brakes when tension disappears, achieving independent start-stop control for multiple take-up drums. Simultaneously, a motor-driven driven shaft drives a reciprocating threaded slider to move linearly along a guide rod, combined with a tensioning wheel for guidance, ensuring that the wire rope is evenly arranged on the side wall of the take-up drum. Furthermore, a movable pulley is designed to dynamically slide with tension, transmitting displacement through a movable pulley mounting plate and absorbing impact force in real time. This ensures stable tension while avoiding the risk of rope breakage, significantly improving the efficiency and safety of multi-take-up collaborative operations.

[0006] The technical solution adopted by this invention is as follows: This solution provides a wire rope winding device, comprising a support frame and a motor. The support frame ensures that the components maintain a stable relative position during operation. The motor is fixedly mounted on the bottom wall of the support frame and serves as a power source, driving a transmission shaft to rotate via an output shaft, providing power to the winding drum for winding the wire rope. A transmission shaft is coaxially fixedly connected to the output shaft of the motor, transmitting the motor's power to the winding drum. Winding drums are rotatably connected in an array on the transmission shaft, winding the wire rope. Rotation orderly winds the wire rope onto its side wall. An external gear arc plate is fixedly provided on the side wall of each winding drum, allowing independent operation for each individual winding drum. To prevent the winding drum from rotating, a driven shaft is rotatably connected to the support frame. The driven shaft is connected to the drive shaft via a belt drive, receiving power from the drive shaft and driving the driven shaft to rotate. A reciprocating guide mechanism is provided on the reciprocating thread section, which performs reciprocating linear motion with the driven shaft, ensuring that the wire rope is evenly arranged on the winding drum and improving winding quality. A tension wheel is fixedly installed on the reciprocating guide mechanism to effectively transmit tension, prevent the wire rope from breaking due to excessive tension, and ensure the stability of the winding tension. A limit rod is slidably installed on the reciprocating guide mechanism. The limit rod moves in contact with the external gear arc plate. The tension change of the tension wheel automatically controls the movement of the limit rod against the external gear arc plate, unlocking during winding and braking after completion.

[0007] Furthermore, the limiting rod includes a driven rod and a limiting vertebral plate. The driven rod is slidably connected to the reciprocating guide mechanism. The up and down movement of the driven rod drives the limiting vertebral plate to move. The limiting vertebral plate is fixedly set on the circumferential wall of the driven rod. The limiting vertebral plate moves in contact with the external gear arc plate. When it contacts the external gear arc plate, it brakes the winding drum.

[0008] Furthermore, a return spring is fixedly provided on the driven rod, and the other end of the return spring is fixedly connected to the reciprocating guide mechanism. When the tension of the wire rope disappears, it pushes the driven rod to return to its original position, so that the limiting cone plate abuts against the external gear arc plate.

[0009] Furthermore, the tensioning wheel includes a fixed pulley and a movable pulley. The fixed pulley is rotatably connected to the reciprocating guide mechanism to guide the wire rope and change the direction of the force. The movable pulley is slidably connected to the reciprocating guide mechanism and moves up and down under the tension of the wire rope to relieve tension impact and change the position of the movable pulley mounting plate.

[0010] Furthermore, the reciprocating guide mechanism includes a slider, a fixed plate, and a guide rod; the slider is threadedly connected to the driven shaft and performs reciprocating linear motion as the driven shaft rotates, driving the tension wheel and the limit rod to move; the fixed plate is rotatably mounted on the driven shaft, providing an installation base for the limit rod; one end of the guide rod is fixedly connected to the side wall of the support frame, and the other end of the guide rod passes through the fixed plate and the slider; the guide rod restricts the fixed plate from moving with the driven shaft, ensuring that the movement trajectory of the slider is linear and ensuring the stability of the reciprocating motion.

[0011] Furthermore, a fixed pulley mounting plate is fixedly provided on the side wall of the slider to fix the fixed pulley and ensure that the position of the fixed pulley is stable. A movable pulley mounting plate is slidably provided on the side wall of the slider. The movable pulley mounting plate is in contact with the limiting rod to transmit the displacement caused by tension.

[0012] The beneficial effects achieved by the present invention using the above structure are as follows:

[0013] (1) The control of the winding drum is realized by utilizing the tension of the wire rope and the mechanical properties of the return spring. When tension is generated during the winding process of the wire rope, the moving pulley is subjected to force and drives the driven rod to move upward through the moving pulley mounting plate, so that the limiting cone plate pushes the external gear arc plate to mesh with the internal gear. At this time, the winding drum can rotate freely. After the tension disappears, the return spring pushes the external gear arc plate to reset, and the external gear arc plate disengages from the internal gear. The automatic start and stop of a single winding drum is realized, and the working status of each winding drum is controlled. It is especially suitable for scenarios where multiple winding drums are working at the same time, which improves work efficiency.

[0014] (2) When the motor starts and drives the transmission shaft to rotate, the driven shaft rotates synchronously through the belt drive. The reciprocating thread section on the driven shaft drives the slider to make a stable reciprocating linear motion along the guide rod. The guide column guides the direction of the wire rope, so that the wire rope can be arranged in an orderly and uniform manner on the winding drum, effectively avoiding the phenomenon of overlapping and random winding.

[0015] (3) When the movable pulley is subjected to tension, it can drive the driven rod to move through the movable pulley mounting plate, change its own position, effectively absorb and relieve tension, and ensure the safety and smoothness of the entire winding process.

[0025] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0026] Example 1: Please refer to Figures 1-7This embodiment provides a wire rope winding device, including a support frame 1 and a motor 2. The motor 2 is fixedly mounted on the side wall of the support frame 1. A transmission shaft 3 is coaxially fixedly connected to the output shaft of the motor 2. An internal gear is fixedly mounted on the circumferential wall of the transmission shaft 3. A winding drum 4 is rotatably connected to the transmission shaft 3. The winding drum 4 includes an inner bushing and a baffle fixedly mounted on the outer wall of the inner bushing. The inner bushing of the winding drum 4 is rotatably connected to the transmission shaft 3 for winding the wire rope. The baffle of the winding drum 4 is used to prevent the wire rope from detaching from the inner bushing of the winding drum 4. An external gear arc plate 5 is slidably mounted on the side wall of the baffle of the winding drum 4. The external gear arc plate 5 meshes with the internal gear. Two external gear arc plates 5 are symmetrically arranged. A hydraulic line 51 is fixedly installed on the side wall of the winding drum 4, and hydraulic oil is contained in the hydraulic line 51. A push rod 52 is fixedly installed on the side wall of the external gear arc plate 5. The push rod 52 is slidably engaged with the hydraulic line 51. The push rod 52 pushes the hydraulic oil to synchronously change the position of the external gear arc plate 5. A return spring 53 is fixedly installed on the push rod 52, and the other end of the return spring 53 is fixedly connected to the side wall of the winding drum 4. A driven shaft 6 is rotatably connected to the support frame 1. The driven shaft 6 is connected to the transmission shaft 3 by belt drive. Reciprocating threaded sections 61 are arranged in an array on the driven shaft 6. A reciprocating guide mechanism 7 is provided on the reciprocating threaded sections 61. The reciprocating guide mechanism 7 includes a slider 71 and a fixed plate 72. The slider 71 is threadedly connected to... On the reciprocating threaded section 61 of the driven shaft 6, symmetrically distributed guide posts 713 are fixedly installed on the top wall of the slider 71. A groove is formed on the inner wall of each guide post 713. A fixed pulley mounting plate 711 is symmetrically fixed on the side wall of one of the guide posts 713. A movable pulley mounting plate 712 slides within the groove on the inner wall of the guide post 713. The movable pulley mounting plate 712 movably abuts against the limiting rod 9. A fixed plate 72 is symmetrically rotatably mounted at both ends of the reciprocating threaded section 61. A guide rod 73 is fixedly connected to the side wall of the support frame 1, with the other end of the guide rod 73 passing through the fixed plate 72 and the slider 71. A fixed pulley 81 and a movable pulley 82 are provided on the reciprocating guide mechanism 7. The fixed pulley 81 is rotatably connected to the fixed pulley. On the side wall of the mounting plate 711, there are two fixed pulleys 81, and a movable pulley 82 is rotatably connected to the inner wall of the movable pulley mounting plate 712, with the movable pulley 82 positioned between the two fixed pulleys 81. A limit rod 9 is slidably provided on the reciprocating guide mechanism 7, and the limit rod 9 is in contact with the external gear arc plate 5. The limit rod 9 includes a driven rod 91 and a limit cone 92. The driven rod 91 is slidably disposed in the groove on the inner wall of the guide column 713, and is located on the upper side of the movable pulley mounting plate 712 to match the displacement state of the movable pulley mounting plate 712 as it moves with the slider 71. The limit cone 92 is fixedly disposed at the bottom end of the driven rod 91, and is in contact with the external gear arc plate 5.

[0027] The principle of this scheme is as follows: During the wire rope winding process, the tension generated by the wire rope acts on the movable pulley 82, which drives the driven rod 91 to slide upward through the movable pulley mounting plate 712. The upward sliding of the driven rod 91 raises the limiting cone plate 92, and the limiting cone plate 92 pushes the external gear arc plate 5 to slide inward, reducing the tooth backlash. At this time, the external gear arc plate 5 meshes with the internal gear on the transmission shaft 3, and the winding drum 4 rotates freely under the drive of the transmission shaft 3 to perform the wire rope winding operation; when a winding drum 4 completes the wire rope winding task, the wire rope... The end of the wire rope disengages from the movable pulley 82, and the tension in the wire rope disappears. Under the weight of the driven rod 91, the movable pulley mounting plate 712, and the movable pulley 82 itself, the driven rod 91 moves the limiting cone plate 92 downward. The external gear arc plate 5 moves away from the transmission shaft 3 under the action of the return spring 53. The external gear arc plate 5 disengages from the internal gear of the transmission shaft 3, thus braking the winding drum 4 and stopping its rotation. The winding drum 4, which has not yet completed its winding task, continues to operate until the entire wire rope winding task is completed.

[0028] In this embodiment, when performing the wire rope winding task, the user first passes the wire rope to be wound through the guide post 713, and then the wire rope passes sequentially around the fixed pulley 81 and the movable pulley 82. Specifically, according to the predetermined routing method, the wire rope passes sequentially around the upper surface of the two fixed pulleys 81 and the lower surface of the movable pulley 82. This routing layout ensures that the tension of the wire rope is effectively applied to the movable pulley 82, generating an upward driving force. At the same time, the movement of the movable pulley 82 alleviates the situation of excessive tension and absorbs the winding and unwinding of the wire. During the process, the tension impact caused by the start-up causes the wire rope to pass over the lower surface of the movable pulley 82. The diameter of the wire rope causes the movable pulley 82 to slide upward, and the driven rod 91 slides upward. At the same time, the limiting cone plate 92 is raised. The limiting cone plate 92 pushes the external gear arc plate 5 to slide inward. The external gear arc plate 5 meshes with the internal gear on the transmission shaft 3, causing the winding drum 4 to enter the winding operation process and rotate with the transmission shaft 3. After one end of the wire rope is fixed on the winding drum 4, the motor 2 is started, and the device begins to enter the winding operation process.

[0029] After the motor 2 starts, the torque output by the motor 2 is transmitted to the winding drum 4 through the transmission shaft 3. The transmission shaft 3 and the winding drum 4 rotate synchronously. At the same time, under the action of the belt, the driven shaft 6 also starts to rotate synchronously. During the rotation of the winding drum 4, the wire rope is wound orderly on the inner bushing of the winding drum 4. During this process, the reciprocating thread section 61 on the driven shaft 6 drives the slider 71 to make reciprocating linear motion along the guide rod 73, so as to achieve precise guidance of the winding position of the wire rope, ensure that the wire rope is evenly arranged on the inner bushing of the winding drum 4, and avoid overlapping.

[0030] As the winding operation continues, the tension generated by the wire rope during winding will act on the movable pulley 82. Under the action of tension, the movable pulley 82 drives the driven rod 91 to slide upward through the movable pulley mounting plate 712. The upward sliding of the driven rod 91 simultaneously raises the limiting cone plate 92, causing the limiting cone plate 92 to further compress the external gear arc plate 5 and slide inward, reducing the tooth clearance. The winding drum 4 can rotate freely under the drive of the transmission shaft 3, and continue to wind the wire rope.

[0031] When a winding drum 4 completes its wire rope winding task, the end of the wire rope disengages from the movable pulley 82, and the wire rope tension disappears. Under the action of the driven rod 91, the movable pulley mounting plate 712, and the gravity of the movable pulley 82, the driven rod 91 drives the limiting cone plate 92 to move downward. Under the action of the return spring, the external gear arc plate 5 moves away from the transmission shaft 3, and the external gear arc plate 5 disengages from the internal gear of the transmission shaft 3, thereby braking the winding drum 4 and stopping its rotation. The winding drums 4 that have not yet completed their winding task continue to operate until all the wire rope winding tasks are completed.

[0032] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
