Description

Technical Field

[0001] This utility model relates to the field of cable winding and unwinding, and in particular to an infrared proximity alarm device for cable reels. Background Technology

[0002] Currently used cables are all in whole rolls. These cables vary in size and do not include cable reels. They are relatively soft and inconvenient to use. It is necessary to rewind the whole roll of cable onto an empty cable reel. The rotation of the cable reel is generally driven by a motor. In the existing technology, when abnormal conditions such as cable breakage or end-of-tie occur during cable reel winding or unwinding, there is no corresponding alarm device to promptly alert the motor, which can easily cause the motor to continue rotating. This can cause the wound cable to swing due to the continued rotation of the motor. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a cable reel infrared proximity alarm device.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A cable reel infrared proximity alarm device includes a support base, a drive motor is installed inside the support base, and an emergency stop component is installed at the end of the drive motor away from the support base. The emergency stop component includes a rotating main shaft, a compression spring is fixedly sleeved at the center of the rotating main shaft, and two compression blocks are fixedly connected to both ends of the compression spring. A compression fixing plate is movably connected to the outer surface of each of the two compression blocks. An outer locking tooth and an inner locking tooth are respectively fixedly connected to the side of each compression block away from the movable fixing plate. The outer locking tooth and the side away from the compression block... An internal gear disk is meshed with one side of the extrusion block, and an external gear disk is meshed with the side of the internal gear disk away from the extrusion block. Movable fixed columns are movably connected to the outer surfaces of both extrusion blocks. Movable columns are fixedly connected to the side of the movable fixed columns away from the extrusion blocks. The side of the movable columns near the movable fixed columns is movably connected to the rotating main shaft. A transmission component is provided on the outer surface of the movable columns. A rotating support disk is fixedly connected to the outer surface of the rotating main shaft. The outer surface of the rotating support disk is fixedly connected to the support sleeve. Rotating cover plates are movably connected to both ends of the support sleeve. A circular slot is opened on the side of the rotating cover plate near the extrusion block.

[0005] As a preferred technical solution of this utility model, the transmission component includes a gear rod, the outer surface of which is movably connected to the rotating cover plate, the end of the drive rod of the drive motor away from the support base being movably connected to the rotating cover plate, an outer gear ring being meshed with the outer surface of the gear rod, the center of the outer gear ring being fixedly connected to the movable column, a fixing block being fixedly connected to the side of the rotating cover plate away from the gear rod, and an inlet column cylinder being fixedly connected to the side of the fixing block away from the rotating cover plate.

[0006] Compared with the prior art, the beneficial effects that this utility model can achieve are:

[0007] This utility model, through the bidirectional meshing and locking design of the inner and outer gear discs and the locking teeth, combined with the elastic force of the compression spring, can quickly lock the inertial rotating support sleeve after the drive motor is powered off. This mechanical linkage structure can achieve millisecond-level bidirectional self-locking, greatly shortening the emergency stop response time and improving the personnel safety protection requirements in high-risk winding scenarios.

[0008] This invention, through the fixed guiding design of the inlet column, not only reduces the tangling problem caused by wire swinging, but also avoids interference of irregular cable movement with the infrared detector signal through physical constraints. It solves the common problem of mechanical motion interfering with sensor signals in traditional winding equipment, and improves the overall stability and detection sensitivity of the system.

[0009] This utility model adopts a vertical meshing transmission layout of gear rod and external gear ring, combined with the linkage design of movable column and rotating main shaft, to achieve integrated arrangement of power transmission and emergency stop components in a limited space. Compared with the traditional coaxial transmission structure, this design significantly improves the compactness of the equipment through three-dimensional spatial staggered layout, while ensuring the coordinated operation efficiency of emergency stop components and transmission components.

[0017] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described herein without creative effort are all within the protection scope of this utility model. Unless otherwise specified, the experimental methods in the following embodiments are conventional methods, and the materials and reagents used in the following embodiments are commercially available unless otherwise specified.

[0018] Example: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the device includes a support base 1, inside which is a drive motor 2. The drive motor 2 is a Mingzhi NEMA6 standard hybrid stepper motor. An emergency stop assembly is provided at the end of the drive motor 2 away from the support base 1. The emergency stop assembly includes a rotating spindle 7, with a compression spring 8 fixedly sleeved at the center of the rotating spindle 7. Two compression blocks 9 are fixedly connected to both ends of the compression spring 8. Compression fixing plates 13 are movably connected to the outer surfaces of the two compression blocks 9. External locking teeth 11 and internal locking teeth 14 are fixedly connected to the side of the two compression blocks 9 away from the movable fixing post 10, respectively. The external locking teeth 11 and internal locking teeth 14 are respectively fixedly connected to the side of the two compression blocks 9 away from the compression block 9. An internal gear disk 12 is connected to the side meshing. An external gear disk 15 is meshed with the side of the internal clamping tooth 14 away from the extrusion block 9. Movable fixed columns 10 are movably connected to the outer surfaces of the two extrusion blocks 9. Movable columns 6 are fixedly connected to the side of the movable fixed columns 10 away from the extrusion blocks 9. The side of the movable column 6 near the movable fixed columns 10 is movably connected to the rotating main shaft 7. A rotating support disk 16 is fixedly connected to the outer surface of the rotating main shaft 7. The outer surface of the rotating support disk 16 is fixedly connected to the support sleeve 19. A rotating cover plate 3 is movably connected to both ends of the support sleeve 19. A circular slot is opened on the side of the rotating cover plate 3 near the extrusion block 9.

[0019] When a worker comes into contact with the danger zone during the winding process, the infrared detection device detects the worker's approach and the control center controls the motor to stop rotating. The motor stopping causes the external gear ring 5 to stop rotating, which inertializes the support sleeve 19. The inertial rotation of the support sleeve 19 causes the rotating support disk 16 to rotate counterclockwise, which in turn causes the rotating main shaft 7 to rotate counterclockwise. The counterclockwise rotation of the rotating main shaft 7 causes the compression spring 8, the compression block 9, and the movable fixed column 10 to rotate counterclockwise. The counterclockwise rotation of the compression block 9 causes the outer locking tooth 11 and the inner locking tooth 14 to rotate counterclockwise. The counterclockwise rotation of the outer locking tooth 11 and the inner locking tooth 14 is jammed by the outer gear disk 15 and the inner gear disk 12, causing the support sleeve 19 to stop rotating.

[0020] like Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the outer surface of the movable column 6 is provided with a transmission assembly, which includes a gear rod 4. The outer surface of the gear rod 4 is movably connected to the rotating cover plate 3. The end of the transmission rod of the drive motor 2 away from the support base 1 is movably connected to the rotating cover plate 3. An external gear ring 5 is meshed with the outer surface of the gear rod 4. The center of the external gear ring 5 is fixedly connected to the movable column 6. A fixing block 17 is fixedly connected to the side of the rotating cover plate 3 away from the gear rod 4. An inlet column cylinder 18 is fixedly connected to the side of the fixing block 17 away from the rotating cover plate 3.

[0021] When the equipment is winding, the worker passes the cable through the inside of the inlet cylinder 18 to prevent the cable from swinging irregularly during the winding process, which could affect the infrared detector. At the same time, the infrared detector starts to detect. After detecting that there is no interference from nearby objects, the control center controls the drive motor 2 to rotate clockwise. The clockwise rotation of the drive motor 2 drives the gear rod 4 to rotate clockwise, which in turn drives the outer gear ring 5 to rotate clockwise. The clockwise rotation of the outer gear ring 5 drives the support sleeve 19 to rotate clockwise to continue winding.

[0022] Working principle:

[0023] Please refer to Figures 1-6 As shown, when a worker comes into contact with the danger zone during the winding process, the infrared detection device detects the worker's approach, and the control center controls the motor to stop rotating. The motor stopping causes the external gear ring 5 to stop rotating, which inertializes the support sleeve 19. The inertial rotation of the support sleeve 19 causes the rotating support disk 16 to rotate counterclockwise, which in turn causes the rotating main shaft 7 to rotate counterclockwise. The counterclockwise rotation of the rotating main shaft 7 causes the compression spring 8, the compression block 9, and the movable fixed column 10 to rotate counterclockwise. The counterclockwise rotation of the compression block 9 causes the outer locking tooth 11 and the inner locking tooth 14 to rotate counterclockwise. The counterclockwise rotation of the outer locking tooth 11 and the inner locking tooth 14 is jammed by the outer gear disk 15 and the inner gear disk 12, causing the support sleeve 19 to stop rotating.

[0024] When the equipment is winding, the worker passes the cable through the inside of the inlet cylinder 18 to prevent the cable from swinging irregularly during the winding process, which could affect the infrared detector. At the same time, the infrared detector starts to detect. After detecting that there is no interference from nearby objects, the control center controls the drive motor 2 to rotate clockwise. The clockwise rotation of the drive motor 2 drives the gear rod 4 to rotate clockwise, which in turn drives the outer gear ring 5 to rotate clockwise. The clockwise rotation of the outer gear ring 5 drives the support sleeve 19 to rotate clockwise to continue winding.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
