Description

Technical Field

[0001] This invention relates to the field of wire harness control, and in particular to a wire harness device with load detection function. Background Technology

[0002] Wire harnesses are devices used to protect athletes, typically consisting of sturdy ropes attached to the athlete's protective harness. Wire harnesses are also used in film production, but the ropes are made of extremely thin steel wire to avoid revealing any flaws.

[0003] If any steel wire breaks or becomes entangled, the wire harness may experience load drop or overload conditions. During the suspension and movement, it may experience overspeed or stall. It is impossible to know whether the specific load condition of the steel wire is normal during use, which makes it impossible to ensure the safety of the user or the personnel being suspended. Summary of the Invention

[0004] The purpose of this invention is to provide a wire harness device with load detection function to solve the problem that the above-mentioned wire harness devices cannot know the specific load of the steel wire during use, resulting in poor safety performance.

[0005] According to one aspect of the present invention, a wire feeding device with load detection function is provided, comprising: a frame, internally connected to a wire feeding roller and a lead screw, a drive device and a wire feeding pulley disposed on one side of the frame, the drive device being rotatably connected to one end of the wire feeding roller, and the other end of the wire feeding roller being driven to the lead screw via a transmission mechanism; a wire turning mechanism, comprising: a turning pulley movably connected within the frame, wherein a wire released from the wire feeding roller is turned by the turning pulley and then enters the wire feeding pulley; a load detection mechanism, comprising: a tension / compression sensor and a threaded block, the threaded block being movably connected to the lead screw, one end of the tension / compression sensor being connected to the wire turning mechanism, and the other end being connected to the threaded block; a detection circuit, a drive circuit, and a display panel, each electrically connected to the tension / compression sensor; the drive device drives the wire feeding roller to rotate while simultaneously driving the lead screw to rotate, causing the load detection mechanism and the wire turning mechanism to move to one side; when the wire is under load, the turning pulley generates a reaction force to resist the movement of the wire turning mechanism, and the tension / compression sensor deforms, causing the detection circuit to send an electrical signal to the display panel.

[0006] As the wire output roller rotates to output wire, the transmission load detection mechanism, together with the wire steering mechanism, moves to one side. When the wire is under load, the steering pulley generates a reaction force to hinder the movement of the wire steering mechanism. The tension and compression sensors deform, causing the detection circuit to send an electrical signal. The specific load on the wire can be seen through the display panel. When a load drop or overload occurs, the operator can be notified and the equipment can be detected immediately, preventing overspeed or stalling during the suspension and movement process, thus improving the safety of the equipment.

[0007] To better address the aforementioned technical deficiencies, the present invention also provides a more preferred technical solution:

[0008] In some embodiments, the wire steering mechanism further includes: a first slide rod, a first connecting plate, and a first slider with a through hole. The first slide rod is connected to the frame and positioned in a vertical tangential direction on one side of the wire output roller. The top two ends of the first connecting plate are respectively connected to the first slider, which is movably connected to the first slide rod. A steering pulley is connected inside the first connecting plate. One of the first sliders is connected to a tension / compression sensor. Thus, the cooperation of the first slide rod and the first slider enables the steering pulley to move stably. The first connecting plate, connected to the bottom of the first slider, ensures that the steering pulley is positioned in a vertical tangential direction on one side of the wire output roller, so that the wire, after being output, is tangential to the steering pulley, avoiding stress-induced wire loss.

[0009] In some embodiments, the load detection mechanism further includes: a second slide rod, a second slider, a third slider, a fourth slider, and a second connecting plate. The second, third, and fourth sliders each have through holes. The second and third sliders are movably connected to the first slide rod. The second slide rod is located on one side of the lead screw. The fourth slider is movably connected to the second slide rod. The second slider, the threaded block, and the fourth slider are respectively connected to the inner side of the second connecting plate. The lower inner part of the third slider is connected to the outer side of the second connecting plate, and the upper inner part of the third slider is connected to a tension / compression sensor. Thus, during the rotation of the lead screw, the threaded block pushes the second connecting plate to move, and the movement of the second connecting plate drives the wire guiding mechanism to move.

[0010] In some embodiments, a third connecting plate is horizontally arranged at the top of the frame, and two safety switches are arranged at the bottom of the third connecting plate. Each safety switch has a sensor pulley at its end, and a gap is provided between the two safety switches. A contact rod is arranged at the top of the second connecting plate, and the contact rod moves within the gap. The safety switches are electrically connected to the drive circuit. When the contact rod contacts the sensor pulley and causes the sensor pulley to rotate, the safety switch disconnects the drive circuit. Therefore, by setting up safety switches, the equipment can be prevented from momentarily overspeeding under load conditions, causing the output roller to rotate excessively and output silk. When the contact rod contacts the sensor pulley and causes the sensor pulley to rotate, the safety switch disconnects the drive circuit to ensure safety.

[0011] In some embodiments, a controller is provided on one side of the drive device, and the controller is electrically connected to the drive circuit. Thus, the controller can preset the operating process of the drive device to achieve automatic yarn feeding.

[0012] In some embodiments, two guide pulleys are connected to both sides of the first connecting plate, and the two guide pulleys are at different heights; two wire feeding pulleys are provided on one side of the frame corresponding to the heights of the two guide pulleys, and the wire feeding direction of the guide pulleys is parallel to the wire feeding direction of the wire feeding pulleys. Thus, providing two guide pulleys at different heights in the wire guiding mechanism can prevent the wires from tangling during wire feeding.

[0013] In some embodiments, the wire feeding pulley includes a hollow wire guide post, a wheel plate, and a pulley. The wire guide post is rotatably mounted on one side of the frame, the wheel plate is connected to the end of the wire guide post, and the pulley is connected inside the wheel plate. This ensures that the wire fed from the guide pulley can directly enter the pulley, preventing stress-induced wire loss.

[0014] In some embodiments, the transmission mechanism includes a transmission gear and a transmission belt. The end of the lead roller and the same-side end of the lead screw are both connected to the transmission gear, and the two transmission gears are connected by the transmission belt. Therefore, the transmission belt has a buffering and vibration-absorbing effect, possesses good elasticity, and provides smooth transmission and buffering / vibration absorption during operation.

[0015] In some implementations, the drive unit is connected to the output roller via a reducer, which is equipped with a brake switch. This reducer prevents the drive unit from starting too abruptly, thus avoiding safety hazards. When the display panel equipment is under abnormal load, the equipment can be stopped by pulling the brake switch.

[0016] In some embodiments, an elastic pressure roller is connected inside the frame and positioned close to the surface of the wire exiting roller. This ensures that the steel wire is perfectly embedded within the wire exiting roller. Attached Figure Description

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] refer to Figures 1 to 7 This application provides a wire feeding device with load detection function, including: a frame 1, internally connected to a wire feeding roller 2 and a lead screw 3; a drive device 4 and a wire feeding pulley 5 are provided on one side of the frame 1; the drive device 4 is rotatably connected to one end of the wire feeding roller 2, and the other end of the wire feeding roller 2 is driven by the lead screw 3 through a transmission mechanism; a wire turning mechanism 6, including: a turning pulley 7 movably connected to the frame 1, through which the wire released from the wire feeding roller 2 is turned and enters the wire feeding pulley 5; and a load detection mechanism, including: a tension / compression sensor 8. The threaded block 9 is movably connected to the lead screw 3. One end of the tension / compression sensor 8 is connected to the wire turning mechanism 6, and the other end is connected to the threaded block 9. The detection circuit and the drive circuit are electrically connected to the tension / compression sensor 8 respectively. The drive device 4 drives the wire output roller 2 to rotate and output wire while simultaneously driving the lead screw 3 to rotate, causing the load detection mechanism and the wire turning mechanism 6 to move to one side. When the wire is under load, the turning pulley 7 will generate a reaction force to resist the movement of the wire turning mechanism 6. The tension / compression sensor 8 will deform, causing the detection circuit to send an electrical signal to the display panel.

[0026] In some embodiments, the drive device 4 is a servo motor.

[0027] The wire turning mechanism 6 also includes: a first slide rod 10, a first connecting plate 11, and a first slider 12 with a through hole. The first slide rod 10 is connected to the frame 1 and is set in the vertical tangential direction on one side of the wire output roller 2. The top two ends of the first connecting plate 11 are respectively connected to the first slider 12. The first slider 12 is movably connected to the first slide rod 10. A turning pulley 7 is connected inside the first connecting plate 11. One of the first sliders 12 is connected to the tension and pressure sensor 8. Through the cooperation of the first slide rod 10 and the first slider 12, the turning pulley 7 can move stably. The first connecting plate 11 is connected to the bottom of the first slider 12 to ensure that the turning pulley 7 is in the vertical tangential direction on one side of the wire output roller 2, so that the wire is tangential to the turning pulley 7 after being output, thus avoiding stress loss of the wire.

[0028] The load detection mechanism also includes: a second slide rod 13, a second slider 14, a third slider 15, a fourth slider 16, and a second connecting plate 17. Each of the second slider 14, third slider 15, and fourth slider 16 has a through hole. The second slider 14 and third slider 15 are movably connected to the first slide rod 10. The second slide rod 13 is located on one side of the lead screw 3. The fourth slider 16 is movably connected to the second slide rod 13. The second slider 14, threaded block 9, and fourth slider 16 are respectively connected to the inner side of the second connecting plate 17. The lower inner side of the third slider 15 is connected to the outer side of the second connecting plate 17. The upper inner side of the third slider 15 is connected to the tension / compression sensor 8. During the rotation of the lead screw 3, the threaded block 9 pushes the second connecting plate 17 to move. During the movement of the second connecting plate 17, the wire turning mechanism 6 moves.

[0029] A third connecting plate 18 is horizontally arranged on the top of the frame 1. Two safety switches 19 are arranged at the bottom of the third connecting plate 18. The ends of the safety switches 19 are equipped with induction pulleys, and a gap is provided between the two safety switches 19. A touch rod 20 is arranged on the top of the second connecting plate 17. The touch rod 20 moves within the gap. The safety switches 19 are electrically connected to the drive circuit. When the touch rod 20 contacts the induction pulley and causes the induction pulley to rotate, the safety switch 19 disconnects the drive circuit. By setting the safety switch 19, the equipment can be prevented from instantly overspeeding under load conditions, causing the output roller 2 to rotate excessively and output silk. When the touch rod 20 contacts the induction pulley and causes the induction pulley to rotate, the safety switch 19 disconnects the drive circuit to ensure safety.

[0030] A controller 21 is provided on one side of the drive device 4. The controller 21 is electrically connected to the drive circuit. The controller 21 can preset the working process of the drive device 4 to realize automatic wire feeding.

[0031] The first connecting plate 11 is connected to two guide pulleys 7 on both sides, and the two guide pulleys 7 are at different heights. Two wire feeding pulleys 5 are set on one side of the frame 1 corresponding to the height of the two guide pulleys 7. The wire feeding direction of the guide pulley 7 is parallel to the wire feeding direction of the wire feeding pulley 5. Setting two guide pulleys 7 at different heights in the wire feeding mechanism 6 can prevent the wires from getting tangled together when feeding.

[0032] The wire feeding pulley 5 includes: a hollow wire guide post 22, a wheel plate 23, and a pulley 24. The wire guide post 22 is rotatably disposed on one side of the frame 1. The wheel plate 23 is connected to the end of the wire guide post 22. The pulley 24 is connected inside the wheel plate 23 to ensure that the wire fed from the steering pulley 7 can directly enter the pulley 24 to prevent stress loss of the wire.

[0033] In some embodiments, the guide post 22 is rotatably connected to one side of the frame 1, and the wire exit angle of the pulley 24 is adjusted by rotating the guide post 22.

[0034] The transmission mechanism includes a transmission gear 25 and a transmission belt 26. The end of the wire output roller 2 and the end of the lead screw 3 on the same side are both connected to the transmission gear 25. The two transmission gears 25 are connected by the transmission belt 26. The transmission belt 26 has a buffering and vibration absorption function. The transmission belt 26 has good elasticity. During operation, the transmission is smooth and can buffer and absorb vibration.

[0035] The drive unit 4 is connected to the wire output roller 2 via a reducer 27. The reducer 27 is equipped with a brake switch 28. The reducer 27 can prevent the drive unit 4 from starting too abruptly, which could lead to safety hazards. When the load on the display panel equipment is abnormal, the equipment can be stopped by pulling the brake switch 28.

[0036] The wire feed roller 2 is provided with a wire groove for accommodating the wire, which effectively reduces the load on each wire and extends the service life of the wire. An elastic pressure roller 29 is connected inside the frame 1. The elastic pressure roller 29 is set close to the surface of the wire feed roller 2. The setting of the elastic pressure roller 29 can ensure that the wire can be perfectly embedded in the wire feed roller 2. The wire groove is provided with a fixing through hole for fixing the wire. The fixing through hole can be used to bind the end of the wire to prevent the wire from derailing.

[0037] In some embodiments, the display panel is also equipped with an alarm connected to the detection circuit. When the tension / compression sensor 8 emits a strong electrical signal, the alarm sounds to alert the operator to pay attention to whether the steel wire is broken.

[0038] The specific usage process of this application is as follows: Multiple units of this device are installed on the ground, and the start time, speed, and number of rotations of the drive device 4 are controlled by the preset controller 21. When a steel wire breaks during the wire extrusion process, the reaction force acting on the steel wire steering mechanism 6 will disappear instantly. The electrical signal emitted by the tension and pressure sensor 8 will be sent to the display panel and the alarm. The operator will then stop the device by using the brake switch 28. When a steel wire becomes entangled during the wire extrusion process, the reaction force pulling the steel wire steering mechanism 6 will gradually increase. When the preset power of the drive device 4 does not match the electrical signal emitted by the tension and pressure sensor 8, the display panel and the alarm will issue a warning.

[0039] The display panel shows the specific load on the steel wire. When a load drop or overload occurs, the operator can immediately detect and inspect the equipment, preventing overspeed or stalling during the suspension and movement process, thus improving the safety of the equipment.
