Description

Technical Field

[0001] The present application relates to the technical field of winch loose rope detection, and in particular to a rope arrangement detection component. Background Art

[0002] A wire rope is a helical bundle of steel wires with suitable mechanical properties and geometric dimensions, twisted together according to specific rules. It consists of steel wires, a core, and lubricating grease. Wire ropes are first twisted into strands from multiple layers of wire, then a predetermined number of strands are twisted around the core to form a spiral. In material handling machinery, they are used for lifting, traction, tensioning, and load bearing. Wire ropes offer high strength, low weight, stable operation, and resistance to sudden breakage, ensuring reliable operation.

[0003] The existing transmission operation uses an unwinding mechanism to transmit the wire rope. During the unwinding / rewinding process, the slack of the wire rope is not wound into the drum of the winch according to regulations, which will cause the rope to jump or become tangled, affecting the secondary use of the wire rope. The staff cannot know the approximate length of the unwound wire rope by the number of unwound turns, and the total unwound wire rope length can only be roughly estimated.

[0004] Therefore, when the length of the wire rope unwound is too long, it needs to be rewound. When the wire rope unwound is too little, it needs to be continued to be unwound. In the overall transmission operation, there is a lack of wire rope detection equipment, and it is impossible to detect the unwinding status of the wire rope in real time and ensure the accuracy of the wire rope transmission. Manual monitoring of the transmission process in real time is required, which affects the overall work efficiency. Utility Model Content

[0005] In order to improve the problem of being unable to conduct real-time detection and ensure transmission accuracy during wire rope transmission operations, and to monitor the transmission wire rope, the present application provides a rope arrangement detection component.

[0006] The present application provides a rope detection assembly that adopts the following technical solutions:

[0007] A rope detection assembly includes a winch, a drive motor installed on the winch, a drum and a guide assembly rotatably arranged on the winch; the drive motor drives the drum in the winch to rotate, and the winch is also equipped with a wire encoder. The guide assembly moves along the detection direction of the wire encoder. The wire encoder is used to detect the actual position distance between the guide assembly through which the wire rope is passed and itself.

[0008] By adopting the above technical solution, after the drive motor is started, the output end of the drive motor drives the drum on the winch to rotate through the steering gear. The drum drives the wire rope to be wound / unwound during the rotation process. The guide assembly is offset along the horizontal direction of the winch. The wire end of the wire encoder is connected to the guide assembly. The wire encoder can measure the length pulled out by the guide assembly, and compare the actual position distance detected with the preset theoretical position distance parameters. If the actual position distance and the theoretical preset position distance are less than the tolerance range, the entire device continues to wind / unwind; if the actual position distance exceeds the tolerance range of the theoretical preset position distance, an alarm is issued to promptly notify the staff and the device is stopped immediately, and then the staff is notified through an automatic alarm whether the actual winding / unwinding of the wire rope exceeds the deviation threshold.

[0009] Optionally, the guide assembly includes a slide and a guide shaft; the guide shaft is fixed on the winch; the slide is slidably arranged on the guide shaft, and a channel for the wire rope to pass through is opened on the slide.

[0010] By adopting the above technical solution, two guide shafts are provided, which are arranged in parallel along the vertical plane. The slide and the two guide shafts slide together, and the channel opened on the slide is in a circular shape. During the transmission process, the wire rope can pass through the circular channel to limit the wire rope, thereby reducing the occurrence of the wire rope deflecting to the surroundings during transmission, and also facilitating the position detection of the wire encoder.

[0011] Optionally, a fastener is installed between the guide shaft and the winch, and the fastener includes a shaft support and a limiting ring. The limiting ring is coaxially arranged on the guide shaft, the shaft support and the winch are bolted, and the guide shaft and the shaft support are clearance-fitted.

[0012] By adopting the above technical solution, shaft supports are installed at both ends of the guide shaft to improve the firmness between the two ends of the guide shaft and the winch. The limit rings are located at both ends of the guide shaft to reduce the contact when the slide moves toward the wire encoder.

[0013] Optionally, the slide includes a slider, a fixed block, a wire pulling plate and a roller shaft, the slider is slidably arranged on the guide shaft, the wire pulling plate is fixedly connected to the top of the slider, the wire pulling plate is fixed to the wire pulling end of the wire pulling encoder, the fixed block is fixedly connected to both sides of the slider, and the roller shaft is rotatably arranged between two fixed blocks along the vertical direction.

[0014] By adopting the above technical solution, the rollers are arranged along the height direction of the slider and are located around the slider. When the wire rope passes through the rollers on all sides, it rolls and cooperates with each other, reducing the friction between the wire rope and the rollers during unwinding / rewinding, thereby improving the transmission efficiency of the wire rope.

[0015] Optionally, a unidirectional spiral thread groove is provided on the drum, and the thread groove and the wound wire rope are engaged one by one.

[0016] By adopting the above technical solution, when the wire rope is wound on the thread groove on the drum, the adjacent wire ropes are in a spaced state, which reduces the occurrence of the wire rope being wound on the drum during winding. The number of turns of the wire rope wound on the thread groove of the drum is proportional to the distance the wire rope is unwound. If the wire rope is wound on the drum without being engaged in the corresponding position or is misplaced, the corresponding unwinding / rewinding distance of the wire rope and the number of turns of the wire rope unwound / rewound on the drum will not correspond, and the slide will produce a certain offset. When the offset distance exceeds the corresponding preset value, an alarm will be issued and the operation will be stopped.

[0017] Optionally, a controller is also installed on the winch; the controller and the wire encoder are connected via electrical signals for receiving / feeding back signals sent by the wire encoder.

[0018] By adopting the above technical solution, the controller processes the data transmitted by the wire encoder and makes instructions and decisions on the corresponding values ​​of the wire encoder.

[0019] Optionally, a support foot is fixed to the bottom of the winch, and a mounting hole for fastening is provided on the support foot.

[0020] By adopting the above technical solution, four support legs are provided, and the four support legs and the winch are integrated through casting. The support legs have a larger contact area relative to the bottom of the winch, which improves the stability of the winch when placed on the construction ground. Six mounting holes are opened on each support leg, and space is reserved for fastening to the installation ground.

[0021] Optionally, a wear-resistant block is further provided on the side of the fixed block in the channel facing away from the slider, and the end of the wear-resistant block is smooth.

[0022] By adopting the above technical solution, the wear-resistant block is fixed on the circular slider. When the wire rope passes through the circular slider, it first contacts the wear-resistant block, which helps to protect the surface of the transmitted wire rope. The smooth end of the wear-resistant block contacts the passing wire rope, reducing the wear of the wire rope by the sharp corners of the wear-resistant block.

[0023] Optionally, a rope guide is further installed on one side of the winch, and the wire rope wound on the winch is passed through a guide assembly and connected to the rope guide.

[0024] The rope guide employs this technology, combining rotation and tension. As the wire rope is fed into the guide, it passes over a series of rotating rollers or drums. These rotate at a specific speed and direction, causing the wire rope to rotate and stretch as it passes through them. This rotation and tension exerts a certain tension on the wires in the rope, causing the wire rope, which exits the winch guide assembly, to realign within the guide.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The wire encoder detects the position of the transmission wire rope. During the unwinding / rewinding process, the wire rope drives the limit-threaded slide to move on the guide shaft, causing a certain amount of offset. If the offset caused by the difference between the actual detected distance and the preset range is within the tolerance range, the reel will continue to operate. If it exceeds the tolerance range, an alarm will be issued to notify the staff and the reel will automatically stop operating, thereby ensuring the unwinding / rewinding accuracy of the wire rope during transmission operations.

[0027] 2. The wire rope is automatically detected and warned in real time by the wire coding device in conjunction with the guide component, which improves the automation level of the wire rope transmission operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0035] The following is combined with Figure 1-5 This application is described in further detail.

[0036] The embodiment of the present application discloses a rope detection assembly.

[0037] Reference Figure 1 A rope arrangement detection component includes a winch 1, a drive motor 2 installed on the winch 1, a drum 9 and a guide component 3 rotatably arranged on the winch 1; the drive motor 2 drives the drum 9 in the winch 1 to rotate, and the winch 1 is also equipped with a wire encoder 4. The guide component 3 moves along the detection direction of the wire encoder 4. The wire encoder 4 is used to detect the actual position distance between the guide component 3 through which the wire rope is passed and itself.

[0038] See also Figure 5 As shown, a rope guide 10 is mounted on one side of the winch 1. The wire rope wound around the winch 1 is threaded through the guide assembly 3 and connected to the rope guide 10. The rope guide 10 combines rotation and tension. As the wire rope is fed into the rope guide 10, it passes over a series of rotating rollers or drums. These rollers or drums rotate at a specific speed and direction, causing the wire rope to rotate and stretch as it passes through them. This rotation and stretching exerts a certain amount of tension on the wire rope, causing the wire rope, which exits the guide assembly 3 on the winch 1, to rearrange itself within the rope guide 10, maintaining wire rope tension.

[0039] The output end of the drive motor 2 drives the steering gear to work, and then drives the drum 9 in the winch 1 to rotate. The transmitted wire rope is passed through the guide assembly 3 and wound on the rope arranger 10. When the wire encoder 4 detects that the offset of the wire rope transmission is within the threshold range, the drum 9 continues to reel / unreel; the difference between the actual position distance of the wire rope detected by the wire encoder and the preset detection distance is the offset. When the wire encoder 4 detects that the offset of the wire rope exceeds the set threshold range, it will cause the wire rope to be unwound / reeled on the drum 9 too fast or too slow, an alarm will be issued and the rotation of the drum 9 will be stopped, thereby ensuring the accuracy of the unwinding / rewinding of the wire rope during the transmission process.

[0040] See also Figure 3As shown, the guide assembly 3 includes a slide 31 and a guide shaft 32; the guide shaft 32 is fixed to the winch 1; the slide 31 is slidably arranged on the guide shaft 32, and a channel for the wire rope to pass through is opened on the slide 31. There are two slides 31, and the slide 31 on each side can transmit a group of wire ropes, reducing the mutual influence of the wire ropes on both sides during transmission. There are two guide shafts 32, which are arranged in parallel along the vertical plane. The slide 31 and the two guide shafts 32 slide together, and the channel opened on the slide 31 is a ring shape; during the transmission process, the wire rope can pass through the ring-shaped channel, limiting the wire rope, reducing the deviation of the wire rope to the surroundings during transmission, and also facilitating the position detection of the wire encoder 4.

[0041] See also Figure 3 and Figure 4 As shown, a fastener 5 is also installed between the guide shaft 32 and the winch 1. The fastener 5 includes a shaft support 51 and a limiting ring 52. The limiting ring 52 is coaxially arranged on the guide shaft 32. The shaft support 51 and the winch 1 are bolted together, and the guide shaft 32 and the shaft support 51 are clearance-matched. The limiting ring 52 is installed on both ends of the guide shaft 32 and near the pre-installed position of the shaft support 51, and is tightened. The limiting ring 52 at both ends of the guide shaft 32 can reduce the situation where the slide 31 touches the wire encoder 4 when it moves toward the wire encoder 4. The shaft support 51 at both ends of the guide shaft 32 improves the firmness of the ends of the winch 1 and the guide shaft 32 after installation, keeps the guide shaft 32 on the horizontal axis, and reduces the situation where the slide 31 jumps when sliding on the guide shaft 32.

[0042] See also Figure 3 As shown, the slide 31 includes a slider 311, a fixed block 312, a wire drawing plate 313 and a roller 314. The slider 311 is slidably arranged on the guide shaft 32. The wire drawing plate 313 is fixedly connected to the top of the slider 311. The wire drawing plate 313 is fixed to the wire drawing end of the wire encoder 4. The fixed block 312 is fixedly connected to both sides of the slider 311. The roller 314 is rotatably arranged between the two fixed blocks 312 along the vertical direction. The wire drawing plates 313 fixed on the slide 31 are staggered. When the wire drawing plates 313 and the slider 311 on both sides move simultaneously, the wire drawing encoder 4 on each side can independently detect one side. The roller 314 is arranged along the height direction of the slider 311 and is located around the slider 311. When the wire rope passes through the rollers 314 on all sides, they roll and cooperate with each other, reducing the friction between the wire rope and the rollers 314 when unwinding / rewinding, thereby improving the transmission efficiency of the wire rope.

[0043] See also Figure 1As shown, a unidirectional spiral thread groove is provided on the drum 9, and the thread groove and the wound wire rope are buckled one by one. When the wire rope is wound on the thread groove on the drum 9, the adjacent wire ropes are in a spaced state, which reduces the occurrence of the wire rope being wound on the drum 9 during winding. The number of turns of the wire rope wound on the thread groove of the drum 9 is proportional to the distance the wire rope is unwound. The wire rope is wound on the drum 9 without being engaged in the corresponding position or is misaligned. The corresponding unwinding / rewinding distance of the wire rope does not correspond to the number of turns of the wire rope unwound / rewound on the drum 9. The slide 31 will produce a certain offset. When the offset distance exceeds the corresponding preset value, an alarm will be issued and the operation will be stopped. For example: the number of thread grooves is 25, and the tolerance range of the allowable offset of the wire rope passing through the slider 311 channel is 50mm. When the wire encoder 4 detects that the spacing of the wire rope driving the slider 311 to slide on the guide shaft 32 exceeds the tolerance range, the system automatically implements an alarm to notify the surrounding staff. When the wire encoder 4 detects that it is at 0~50mm, the wire rope winding / unwinding operation continues.

[0044] See also Figure 2 As shown, the hoist 1 is also equipped with a controller 6; the controller 6 is electrically connected to the wire encoder 4 and is used to receive and feed back signals from the wire encoder 4. The controller 6 processes the data transmitted by the wire encoder 4 and issues instructions and decisions based on the corresponding values ​​of the wire encoder 4. If the spacing detected by the wire encoder 4 exceeds the system's preset offset range, an alarm is issued to notify surrounding personnel and the reel 9 is stopped.

[0045] See also Figure 2 As shown, a support leg 7 is fixed to the bottom of the hoist 1, and each support leg 7 has mounting holes 71 for fastening. There are four support legs 7, which are integrally cast with the hoist 1. The support legs 7 have a large contact area with the bottom of the hoist 1, which improves the stability of the hoist 1 when placed on the construction ground. Each support leg 7 has six mounting holes 71, leaving space for fastening to the ground during installation.

[0046] See also Figure 3 As shown, a wear-resistant block 8 is also provided on the side of the fixed block 312 in the channel facing away from the slider 311. The end of the wear-resistant block 8 is smooth. The wear-resistant block 8 is fixed to the circular slider 311. When the wire rope passes through the circular slider 311, it first contacts the wear-resistant block 8, which helps protect the surface of the transmitted wire rope. The smooth end of the wear-resistant block 8 contacts the passing wire rope, reducing the wear of the wire rope by the sharp corners of the wear-resistant block 8.

[0047] The implementation principle of a rope detection component in an embodiment of the present application is as follows: after the drive motor 2 is started, the protruding end of the drive motor 2 drives the steering gear to work, and then drives the drum 9 in the winch 1 to rotate. During the rotation, the drum 9 drives the wire rope to be wound / unwound, and the guide component 3 is offset along the horizontal direction of the winch 1. The wire end of the wire encoder 4 is connected to the guide component 3. The wire encoder 4 can measure the length pulled out by the guide component 3, and compare the actual position distance detected with the preset theoretical position distance parameter. If the actual position distance and the theoretical preset position distance are less than the tolerance range, the entire device continues to wind / unwind; if the actual position distance exceeds the tolerance range of the theoretical preset position distance, an alarm is issued to promptly notify the staff and the device is stopped immediately, and then the staff is notified through automatic alarm whether the actual winding / unwinding of the wire rope exceeds the deviation threshold, thereby ensuring the unwinding / rewinding accuracy of the wire rope in the transmission operation, performing real-time automatic detection and early warning of the wire rope, and improving the automation level of the wire rope in the transmission operation.
