Description

Technical Field

[0001] This utility model relates to the field of wire harness transfer technology, and in particular to a track-type wire harness transfer device. Background Technology

[0002] New energy wiring harnesses are cable assemblies specifically designed for new energy applications. They are used to connect key components such as battery packs, motor controllers, charging interfaces, and sensors. They are responsible not only for transmitting high-current electrical energy but also for data communication, ensuring that vehicles or equipment can operate efficiently and safely. Compared with traditional automotive wiring harnesses, new energy wiring harnesses need to withstand higher voltages and currents, while also possessing good temperature resistance, anti-interference capabilities, and durability. Therefore, their material selection, structural design, and manufacturing processes are more stringent.

[0003] Most existing devices use simple strapping or fixing slots, requiring operators to manually bind, knot, or forcefully insert the wire harness each time it is loaded. This fixing method not only increases the labor intensity and time consumption of the operators, leading to reduced transfer efficiency, but also makes the strapping prone to loosening or damage during frequent loading and unloading. To address this technical problem, this application proposes a track-type wire harness transfer device. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a track-type wire harness transfer device. After lifting the binding strap, the wire harness is placed on the vehicle body, which presses down the trigger rope to tighten the binding strap and quickly fix the wire harness. The scraper at the front of the vehicle body can effectively remove larger particles of debris attached to the track, ensuring the track is unobstructed and guaranteeing a smooth and stable transfer process.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A track-type wire harness transfer device includes a vehicle body, a front baffle fixedly connected to the top front end of the vehicle body, a protective shell fixedly connected to the top rear end of the vehicle body, a trigger rope fixedly connected to the left end of the front baffle near the protective shell, a tightening assembly disposed inside the protective shell, a fixing bar fixedly connected to the front end of the vehicle body, a plurality of binding straps fixedly connected to the outer wall of the fixing bar, a mounting base fixedly connected to the bottom front end of the vehicle body, a cleaning assembly disposed on the front side of the mounting base, and a wire harness disposed on the top side of the vehicle body, the wire harness being disposed above the trigger rope and below the binding straps.

[0006] Furthermore, the tightening assembly includes a shaft bracket fixedly connected to the rear left side of the vehicle body. A second rolling shaft is rotatably connected to the top of the shaft bracket. A gear is fixedly connected to the outer wall of the second rolling shaft. A ratchet is fixedly connected to the outer wall of the second rolling shaft. One end of the trigger rope is fixedly connected to the outer wall of the second rolling shaft. A pawl is rotatably connected to the side of the protective housing near the ratchet via a torsion spring. The end of the pawl away from the torsion spring abuts against the ratchet. A handle is fixedly connected to the top side of the pawl.

[0007] Furthermore, a first rolling shaft is rotatably connected to the middle end of the shaft frame, one end of the binding strap is fixedly connected to the outer wall of the first rolling shaft, and a second gear is fixedly connected to the outer wall of the first rolling shaft, with the first gear and the second gear meshing together.

[0008] Furthermore, the diameter of gear one is larger than the diameter of gear two, and gear one and gear two have the same tooth module.

[0009] Furthermore, the cleaning component includes a height adjustment seat fixedly connected to the front side of the mounting base. A connecting groove is provided at the middle of the height adjustment seat, and a connector is inserted into the connecting groove. Locking holes are provided at the middle of the left and right sides of the height adjustment seat and at the rear end of the connector. A pin is inserted into the locking hole, and a scraper is sleeved on the outer wall of the connector.

[0012] Furthermore, wheels are installed at the four corners of the bottom side of the vehicle body, and guide rails are provided at the bottom of the wheels, allowing the wheels to slide inside the guide rails.

[0013] This utility model has the following beneficial effects: 1. In this utility model, when the wire harness is placed on the vehicle body, the wire harness will trigger the rope to press down, causing the second rolling shaft to rotate. The second rolling shaft will simultaneously drive the ratchet and the first gear to rotate synchronously. The larger gear will further drive the smaller gear and the first rolling shaft to rotate, increasing the transmitted torque. The binding strap fixed to the outer wall of the first rolling shaft will then wrap around the first rolling shaft and tighten. The elastic binding strap can quickly fix the wire harness, eliminating the tedious manual binding steps and significantly improving loading and unloading efficiency.

[0017] 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.

[0018] Reference Figure 1This utility model provides an embodiment of a track-type wire harness transfer device, comprising a vehicle body 1, with wheels 3 installed at the four corners of the bottom side of the vehicle body 1. Guide rails 2 are provided at the bottom ends of the wheels 3, allowing the wheels 3 to slide within the guide rails 2, ensuring stable movement of the vehicle body 1 along a predetermined path and preventing deviation from the track. A front baffle 6 is fixedly connected to the front top side of the vehicle body 1 to prevent the wire harness 26 from sliding forward during transfer. A protective shell 4 is fixedly connected to the rear top side of the vehicle body 1 to protect internal components and prevent the wire harness 26 from sliding backward. A trigger rope 7 is fixedly connected to the left end of the plate 6 near the protective shell 4. A tightening component is provided inside the protective shell 4. When the wire harness 26 is placed, the trigger rope 7 is pressed down, triggering the tightening component to work and realize automatic binding. A fixing bar 5 is fixedly connected to the front end of the vehicle body 1. Multiple binding straps 8 are fixedly connected to the outer wall of the fixing bar 5. The binding straps 8 are made of elastic material. The tightening component automatically tightens the binding straps 8 by pulling the trigger rope 7. A mounting base plate 9 is fixedly connected to the front end of the bottom side of the vehicle body 1. A cleaning component is provided on the front side of the mounting base plate 9.

[0019] Reference Figure 2 A support frame 11 is fixedly connected to the left rear end of the vehicle body 1, providing a support structure. A second rolling shaft 27 is rotatably connected to the top of the support frame 11. A gear 12 and a ratchet 13 are fixedly connected to the outer wall of the second rolling shaft 27. The gear 12 and the ratchet 13 are coaxial. One end of the trigger rope 7 is fixedly connected to the outer wall of the second rolling shaft 27. When the trigger rope 7 is pulled, it drives the second rolling shaft 27 to rotate, which in turn drives the gear 12 and the ratchet 13 to rotate synchronously. A pawl 14 is rotatably connected to the side of the protective shell 4 near the ratchet 13 via a torsion spring. The pawl 14 is always in contact with the ratchet 13 under the action of the torsion spring. When the ratchet 13 rotates counterclockwise, the teeth of the ratchet 13 contact the inclined surface on the right side of the bottom end of the pawl 14, allowing it to rotate smoothly. When the ratchet 13 rotates clockwise... The teeth contact the vertical surface on the left side of the bottom end of the pawl 14, preventing it from rotating smoothly and achieving one-way locking. A handle 17 is fixedly connected to the top side of the pawl 14 for manually turning the pawl 14 to release the limit on the ratchet 13, thereby releasing the binding strap 8. A rolling shaft 15 is also rotatably connected to the middle end of the shaft frame 11. One end of the binding strap 8 is fixedly connected to the outer wall of the rolling shaft 15. The rolling shaft 15 is used to wind up the binding strap 8. When the gear 2 16 drives the rolling shaft 15 to rotate, the binding strap 8 is stretched, generating a clamping force. The outer wall of the rolling shaft 15 is fixedly connected to the gear 2 16. The gear 12 and the gear 2 16 mesh. The diameter of the gear 12 is larger than the diameter of the gear 2 16. The gear 12 and the gear 2 16 have the same tooth module, realizing the amplification and transmission of torque and ensuring that the binding strap 8 is fully stretched.

[0020] Reference Figures 3-5A height adjustment seat 18 is fixedly connected to the front side of the mounting base 9, allowing the connector 20 to be installed at different heights to meet different cleaning needs. A connecting groove is provided in the middle of the height adjustment seat 18, and the connector 20 is inserted into the groove. Locking holes are provided at the middle of both sides of the height adjustment seat 18 and at the rear end of the connector 20. A pin 19 is inserted into the locking hole to ensure a secure connection between the connector 20 and the height adjustment seat 18. A telescopic rod 22 is fixedly connected to the middle of the left side of the height adjustment seat 18. A limit block 25 is fixedly connected to the bottom side of the telescopic rod 22. A spring 21 is sleeved on the outer wall of the telescopic rod 22, and the top of the spring 21 is fixedly connected to the height adjustment seat 18. The bottom end of spring 21 is fixedly connected to the limiting block 25. The telescopic rod 22 is used to limit spring 21 to prevent it from shifting. The outer periphery of the pin 19 near the limiting block 25 has an annular groove. The limiting block 25 is engaged in the annular groove to lock the pin 19. The outer wall of the connector 20 is fitted with a scraper 10. The scraper 10 can remove particulate debris from the surface of the guide rail 2, keep the wheel 3 sliding smoothly and reduce wear. The left and right sides of the front end of the connector 20 are slidably connected to the limiting sliders 24. The adjacent sides of the two limiting sliders 24 are fixedly connected by spring 23. The limiting sliders 24 extend to both sides under the action of spring 23 to lock the scraper 10, so as to achieve quick fixing and replacement and easy operation.

[0021] Working principle: When using the transfer vehicle, lift the initially relaxed binding strap 8, place the wire harness 26 above the vehicle body 1, and press down the trigger rope 7. At this time, the trigger rope 7, which is wound around the outer circumference of the second rolling shaft 27, is pulled, causing the second rolling shaft 27 to rotate. The second rolling shaft 27 simultaneously drives the ratchet 13 and the first gear 12 to rotate. The first gear 12 further drives the second gear 16, which meshes with the first gear 12, to rotate. The first rolling shaft 15, which is fixedly connected to the middle of the second gear 16, rotates synchronously. Since the diameter of the first gear 12 is larger than that of the second gear 16, and the gears 12 and 16 have the same tooth module, the torque transmitted from the second rolling shaft 27 to the first rolling shaft 15 is increased, ensuring that the binding strap 8 is stretched a sufficiently long distance. The binding strap 8, which is fixedly connected to the outer wall of the first rolling shaft 15, is wound and stretched, and downward pressure is applied. Because the binding strap 8 is elastic, it generates a continuous elastic restoring force during the stretching process, pressing the wire harness 26. At the same time, because... The pawl 14 restricts the rotation of the ratchet 13, further preventing the rotation of the rolling shaft 15, so that the binding strap 8 continuously generates pressure. When unloading the wire harness 26, the pawl 14 is moved by the handle 17 to release the restriction on the ratchet 13. At this time, the rolling shaft 15 can rotate, and the binding strap 8 quickly relaxes and retracts, releasing the restraint on the wire harness 26. The height adjustment seat 18 at the front end of the vehicle body 1 has connecting slots of different heights in the middle. The connector 20 is inserted into the connecting slot and locked with the pin 19. The spring 21 and the limit block 25 on the right side of the middle end of the height adjustment seat 18 lock the pin 19 again to ensure stable connection. The telescopic rod 22 is used to limit the spring 21. When the scraper 10 needs to be replaced, the limit slider 24 is pressed inward to remove the scraper 10 from the connector 20. After installing the new scraper 10, the spring 23 inside the connector 20 pushes the limit slider 24 to both sides to limit the scraper 10.
