Description

Technical Field

[0001] This utility model relates to the field of wire rope laying technology, and in particular to a wire rope laying device with automatic adjustment function. Background Technology

[0002] Wire rope is a helical bundle of steel wires that meet the requirements of mechanical properties and geometric dimensions, twisted together according to certain rules. Wire rope consists of steel wires, a core, and lubricant. Wire rope is first made by twisting multiple layers of steel wires into strands, and then, with the core as the center, a certain number of strands are twisted into a helical rope. When producing wire rope or processing it as raw material, the wire is often released by placing the central hole of the wire reel onto the rotating shaft of the rotating disc.

[0003] A search revealed that Chinese Patent Publication No. CN215755635U discloses a wire rope unloading device with an automatic adjustment function. A fan-shaped pendulum is coaxially fixed at the rotation axis of the swing arm. When the swing arm hangs down naturally, the center of gravity of the fan-shaped pendulum is at its lowest. By adding an eccentrically set fan-shaped pendulum, gravity can be used to make the swing arm and the wire guide wheel swing down autonomously, thereby tightening the wire rope and achieving tensioning of the wire rope.

[0004] The aforementioned device uses the weight of the fan-shaped pendulum to tighten the wire rope on the guide wheel. However, the weight of the fan-shaped pendulum is fixed, so the gravity it can provide is limited. Consequently, the guide wheel can only provide a constant tension to tighten the wire rope. Since different diameter wire ropes require different tensions, and the device can only tighten the wire rope with constant pressure, it is prone to slippage or shaking during the wire rope release process due to slackness, resulting in poor applicability. Therefore, a wire rope release device with an automatic adjustment function is proposed to solve the above problems. Utility Model Content

[0033] 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.

[0034] Reference Figures 1-3 This utility model provides an embodiment of a wire rope unloading device with automatic adjustment function, including a frame 1. A drive assembly 2 is fixedly connected to the top of the frame 1. The drive assembly 2 consists of a servo motor and a drive shaft, etc., and is used to control the rotation of the I-beam reel. A tension sensor 3 is fixedly connected to the side wall of the frame 1. The tension sensor 3 is electrically connected to the control equipment. The tension sensor 3 can be a FUTEK LSB200 series axial tension sensor 3. The tension sensor 3 detects the tension of the wire rope in real time and feeds it back to the control system to achieve closed-loop adjustment. A rotating rod 4 is rotatably connected to the inner wall of the tension sensor 3. A pressure rod 5 is fixedly connected to the end of the rotating rod 4 away from the tension sensor 3. A tension wheel 6 is rotatably connected to the bottom end of the pressure rod 5. The pressure rod 5 and the tension wheel 6 can provide tension and guidance for the wire rope. A tension adjustment mechanism and a disassembly mechanism 9 are provided on the side wall of the frame 1.

[0035] Reference Figures 1-3 The tension adjustment mechanism includes an adjustment component 7, which includes a rocker arm 71. The rocker arm 71 is hinged to the side wall of the frame 1. The rocker arm 71 is a hollow rod-shaped structure. A connecting rod 72 is fixedly connected to the bottom of the pressure rod 5 and the side away from the tension wheel 6. The connecting rod 72 has a "Z" shaped structure. The end of the connecting rod 72 away from the tension wheel 6 is attached to the inner wall of the rocker arm 71. The weight of the rocker arm 71 can provide downward pressure to the pressure rod 5, thereby maintaining the tension wheel 6 with appropriate tension. A slider 73 is slidably connected to the inner wall of the rocker arm 71. A groove 74 is provided on the side wall of the slider 73. When the locking block 91 is inserted into the groove 74, the counterweight block 75 can be connected to the slider 73. The counterweight block 75 is engaged with the inner wall of the groove 74, and the weight of the slider 73 can be increased by the counterweight block 75.

[0036] Reference Figure 2 , Figure 3 and Figure 6, the tension adjustment mechanism further includes a positioning component 8. The positioning component 8 includes a slide plate 81 which is slidably connected to the inner wall of the slider 73. One side of the slide plate 81 is fixedly connected with a rubber block 82. The slider 73 can be limited to the outer wall of the swing rod 71 by the frictional force of the rubber block 82 in cooperation with the slide plate 81. The other side of the slide plate 81 is fixedly connected with a push plate 83. An inclined groove 84 is formed on the push plate 83. A button 85 penetrates and is slidably connected to the inner wall of the slider 73. The bottom of the button 85 is fixedly connected with a guide rod 86 for pushing the push plate 83. The outer wall of the guide rod 86 is fitted to the inner wall of the inclined groove 84. When the button 85 slides, the push plate 83 can be pushed in cooperation with the guide rod 86 and the inclined groove 84, so that the slide plate 81 is driven to slide on the inner wall of the slider 73. The bottom of the button 85 is fixedly connected with a return spring 87. By pinching the buttons 85 at the upper and lower ends of the slider 73, the buttons 85 can slide into the slider 73 and compress the return spring 87. The end of the return spring 87 away from the button 85 is fixedly connected to the inner wall of the slider 73. The elasticity of the return spring 87 can drive the button 85 to slide back to its original position.

[0037] Referring to Figures 3-5 , the disassembly and assembly mechanism 9 includes a clamping block 91. The clamping block 91 penetrates and is slidably connected to the counterweight 75. The two counterweights 75 can be butted together through the cooperation of the clamping block 91 and the clamping groove 94. An inclined surface 92 is formed on the inner wall of the clamping block 91. A clamping groove 94 with the same size as the groove 74 is formed at the bottom end of the counterweight 75. One end of the clamping block 91 is fitted to the inner wall of the clamping groove 94. The other end of the clamping block 91 is fixedly connected with a limiting spring 95. The end of the limiting spring 95 away from the clamping block 91 is fixedly connected to the inner wall of the counterweight 75. The elasticity of the limiting spring 95 can drive the clamping block 91 to slide out of the counterweight 75, and then the clamping block 91 can be inserted into the inner part of the clamping groove

[0038] Working principle: During use, the wire rope is passed under the tensioning wheel 6. The weight of the counterweight 75, along with the slider 73, the swing rod 71, and the connecting rod 72, keeps the tensioning wheel 6 under downward pressure, thus maintaining appropriate tension in the wire rope during unwinding. When the tension of the wire rope increases suddenly, it pushes the tensioning wheel 6 upward. At this time, the tensioning wheel 6 pushes the pressure rod 5 upward, causing the pressure rod 5 to rotate the rotating rod 4. The tension sensor 3 monitors the tension fluctuation of the rotating rod 4 and sends an electrical signal to the control device. The control device then increases the rotation speed of the drive assembly 2. The speed of the drive assembly 2 is increased. When the tension of the wire rope drops suddenly, the counterweight 75, in conjunction with the slider 73, swing rod 71, and connecting rod 72, causes the tension wheel 6 to swing downward. At this time, the tension wheel 6 will cause the pressure rod 5 to swing downward, causing the pressure rod 5 to drive the rotating rod 4 to rotate. The tension sensor 3 monitors the tension fluctuation of the rotating rod 4 and sends an electrical signal to the control device. The control device reduces the speed of the drive assembly 2, so that the wire rope can be controlled to prevent derailment and maintain the continuity of wire rope laying when the tension of the wire rope increases or decreases suddenly.

[0039] By pressing the buttons 85 at both ends of the slider 73, it can slide inward and compress the return spring 87. Simultaneously, the buttons 85 cause the guide rod 86 to move against the inner wall of the inclined groove 84. The guide rod 86 then pushes the push plate 83, causing the push plate 83 to gradually slide the slide plate 81 inward. This allows the rubber block 82 on the side wall of the slide plate 81 to separate from the side wall of the rocker arm 71. At this point, the slider 73 can be pushed to slide against the outer wall of the rocker arm 71, thus adjusting its position. Once adjustment is complete, the buttons 85 can be released. 5. At this time, under the elastic action of the return spring 87, the button 85 will slide to reset. At the same time as the button 85 slides to reset, the guide rod 86 will move synchronously. At this time, the guide rod 86 will move against the inner wall of the inclined groove 84 and push the push plate 83, so that the push plate 83 will drive the slide plate 81 to gradually slide towards the side of the swing rod 71. In this way, the rubber block 82 on the side wall of the slide plate 81 can be pressed tightly against the side wall of the swing rod 71. At this time, the friction of the rubber block 82, together with the slide plate 81, can limit the slider 73 to the outer wall of the swing rod 71, so that the slider 73 remains stable.

[0040] When slider 73 moves along the rocker arm 71 away from its hinge point with frame 1, the lever arm of counterweight 75 increases significantly. With the weight of counterweight 75 remaining constant, according to the lever principle, this will cause the center of gravity of the entire rocker arm 71 system to gradually shift outward, away from the hinge point. As the position of the center of gravity changes, the gravitational torque generated by the rocker arm 71 at the hinge point increases non-linearly, significantly enhancing the rotational tendency of the rocker arm 71 around the hinge point. Since the connecting rod 72 is attached to the inner wall of the rocker arm 71, this enhanced rotational tendency will directly translate into the force exerted on the rocker arm 71. The downward pressure of the connecting rod 72 is transmitted and amplified through the pressure rod 5, and finally acts on the tensioning wheel 6. As a result, the tensioning wheel 6 can generate a stronger clamping force, which can be adapted to steel wire ropes with larger diameter and stronger rigidity, ensuring a stable and reliable tensioning effect under various working conditions. This effectively avoids slippage and shaking caused by the slack of the steel wire rope. Conversely, when the slider 73 gradually approaches the hinge point between the swing rod 71 and the frame 1, the tensioning force provided by the pressure rod 5 and the tensioning wheel 6 to the steel wire rope will gradually weaken, so as to provide a reasonable tensioning force for thinner steel wire ropes.

[0041] When it is necessary to increase the counterweight mass of slider 73, press the push rod 93 inside one set of counterweight blocks 75, causing the push rod 93 to slide inward into the counterweight block 75. At the same time, the end of the push rod 93 will press against the inclined surface 92, causing the locking block 91 to slide inward into the counterweight block 75 and compress the spring. Then, insert the top of the counterweight block 75 into the locking groove 94 at the bottom of the other set of counterweight blocks 75. After the two sets of counterweight blocks 75 are aligned, release the push rod 93 to stop pressing against the inclined surface 92. At this time, the limiting spring 9... Under the elastic action of 5, the locking block 91 can be driven to slide to the outside of the counterweight block 75, so that the locking block 91 can be locked into the inside of the locking groove 94. At this time, with the cooperation of the locking block 91 and the locking groove 94, the two sets of counterweight blocks 75 can be limited together, thus completing the docking of the two sets of counterweight blocks 75. By repeating the above operation, multiple counterweight blocks 75 can be docked together, thereby increasing the number of counterweight blocks 75 of the slider 73, so that the slider 73 can provide greater gravity for the swing arm 71, in order to accommodate thicker steel wire ropes.

[0042] 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.
