Such changes will not hinder the understanding of those skilled in the art.

[0040] According to one aspect of this disclosure, an overhead cable conveying device for locomotives is provided, comprising an overhead conveyor line, a conveying fixture 3, and a lifting mechanism. (See attached document) Figures 1 to 7As shown, the aerial conveyor line includes a track 1 and a support frame 2. The track 1 is erected in the air by the support frame 2. The bottom of the conveyor carriage 3 has a moving mechanism for moving on the ground, and the top of the conveyor carriage 3 has a lifting ring for connecting with the lifting mechanism. The first end of the lifting mechanism is slidably connected to the track 1 through a sliding plate 41, and the second end of the lifting mechanism opposite to the first end is detachably connected to the lifting ring. The first end and the second end are retractably arranged to allow the conveyor carriage 3 to be lifted or lowered.

[0041] The conveying fixture 3 has a cable receiving cavity 31, a first cable fixing part 32 and a second cable fixing part 33. The track 1 has a cable unloading area 11, a cable prefabrication area 12 and a wiring area 13 connected in sequence. The conveying fixture 3 is used to lower the cable unloading area 11 to the ground, receive the cable to be processed through the cable receiving cavity 31 and lift it. The conveying fixture 3 is used to lower the cable prefabrication area 12 to the ground, fix the prefabricated cable through the first cable fixing part 32 and lift it. The conveying fixture 3 is used to lower the wiring area 13 to the ground, fix the finished template wire harness through the second cable fixing part 33, and leave the locomotive cable aerial conveying device from the ground through the moving mechanism.

[0042] The locomotive cable aerial transport device disclosed herein allows the transport fixture 3 to move on the ground via a moving mechanism and be lifted into the air via a lifting mechanism, sliding along the track 1. The transport fixture 3 can slide between the cable unloading area 11, the cable prefabrication area 12, and the wiring area 13 via the track 1, and can be lowered to the ground in all three areas to carry different types of cable bundles. Specifically, the transport fixture 3 accommodates the semi-finished cables to be processed in the cable unloading area 11 via the cable receiving cavity 31; fixes the prefabricated cables with terminals and other accessories assembled in the cable prefabrication area 12 via the first cable fixing part 32; and fixes the finished template cable bundle formed after wiring the prefabricated cables in the wiring area 13 via the second cable fixing part 33, and can transport the finished template cable bundle away from the ground.

[0043] The locomotive cable aerial conveying device disclosed herein can automatically and orderly deliver semi-finished cables and finished template wire harnesses to various work-in-process stations via conveying tooling 3. This solves the problem of needing to use multiple tooling trolleys for the storage and transportation of various cables on site, and the problem of easy congestion on the ground. It improves the efficiency and accuracy of conveying and saves manpower.

[0044] Specifically, in conjunction with the processing and manufacturing process of locomotive cables, the working process of the locomotive cable overhead conveying device disclosed herein is provided. (Reference) Figure 4As shown, track 1 has a cable unloading area 11, a cable prefabrication area 12, and a wiring area 13. Bundles of cables are cut into segments below the cable unloading area 11 and loaded into the cable receiving cavity 31 before being hoisted onto track 1. The cable unloading area 11 may include a large cable unloading area 111 and a small cable unloading area 112. For example, cables with a diameter of 10 square millimeters or more are cut into segments below the large cable unloading area 111 and loaded into the cable receiving cavity 31 before being hoisted onto track 1; cables with a diameter of less than 10 square millimeters are cut into segments below the small cable unloading area 112 and loaded into the cable receiving cavity 31 before being hoisted onto track 1.

[0045] For example, the second end of the lifting mechanism is provided with a hook for connecting with the lifting ring on the top of the conveying tooling vehicle 3. The hook can move up and down as needed to lift or lower the conveying tooling vehicle 3 to adapt to the needs of different workstation heights.

[0046] For example, a drive device is provided on the track 1 to drive the conveyor carriage 3 to move on the track 1. After the conveyor carriage 3 loads the cable to be processed in the cable unloading area 11, it slides along the track 1 to the cable prefabrication area 12 under the drive of the drive device. The conveyor carriage 3 is lowered to the ground in the cable prefabrication area 12, and the terminals and other accessories are assembled by mechanical or manual means to form a prefabricated cable, which is then fixed by the first cable fixing part 32, and then hoisted onto the track 1.

[0047] Driven by the drive unit, the conveyor trolley 3 slides along the track 1 to the wiring area 13. The conveyor trolley 3 is lowered to the ground in the wiring area 13 and wiring is performed. The scattered prefabricated cables are assembled and bundled into finished template wire harnesses. The finished template wire harnesses are then transported from the ground to the locomotive cable aerial conveyor via a moving mechanism, for example, to the electrical cabinet assembly area, where they are installed into the electrical cabinet.

[0048] For example, the moving mechanism includes rollers, that is, the bottom of the conveyor carriage 3 has rollers. The conveyor carriage 3 may have an interface compatible with an Automated Guided Vehicle (AGV), so that the conveyor carriage 3 can be carried by an AGV trolley. After the finished template wire harness is loaded, the conveyor carriage 3 can be transported by an AGV trolley to the aerial conveyor device for locomotive cables that leaves the ground.

[0049] In one exemplary embodiment of this disclosure, the aerial conveyor line also includes a protective net 5. (See reference...) Figure 1 and Figure 2As shown, the protective net 5 is installed between the track 1 and the ground, and the orthographic projection of the track 1 onto the ground is within the range of the protective net 5. The protective net 5 can be made of metal mesh, and the aperture of the protective net 5 is smaller than the outer diameter of the cable. If the cable inside the conveyor trolley 3 accidentally falls, the protective net 5 can catch the falling cable and prevent it from falling to the ground and causing danger.

[0050] In one exemplary embodiment of this disclosure, the protective net 5 has a first loading / unloading port, a second loading / unloading port, and a third loading / unloading port that pass through the protective net 5. The first loading / unloading port corresponds to the cable unloading area 11, allowing the conveying fixture 3 to pass through the first loading / unloading port for lifting or lowering within the cable unloading area 11. The second loading / unloading port corresponds to the cable prefabrication area 12, allowing the conveying fixture 3 to pass through the second loading / unloading port for lifting or lowering within the cable prefabrication area 12. The third loading / unloading port corresponds to the wiring area 13, allowing the conveying fixture 3 to pass through the third loading / unloading port for lifting or lowering within the wiring area 13. The protective net 5 defines the lifting and lowering positions of the conveying fixture 3 through the loading / unloading ports (e.g., the first, second, and third loading / unloading ports), thereby improving the safety of the locomotive cable overhead conveying device.

[0051] For example, the cable unloading area 11 may include a large cable unloading area 111 and a small cable unloading area 112. Both the large cable unloading area 111 and the small cable unloading area 112 are provided with first loading and unloading ports, which are respectively used to lift and lower the tooling car 3 in the large cable unloading area 111 and the small cable unloading area 112 to lift and transport the corresponding cables to be processed to the cable prefabrication area 12.

[0052] In one exemplary embodiment of this disclosure, the lifting mechanism refers to Figure 3 As shown, the lifting mechanism includes an electric hoist scissor lift structure. After the conveying carriage 3 moves to the loading / unloading position (e.g., the first loading / unloading port, the second loading / unloading port, and the third loading / unloading port), the lifting mechanism adopts a sliding contact power supply, which is safe and stable. For example, the electric hoist motor of the lifting mechanism has a braking function and can automatically lock in the event of a power outage. The conveying carriage 3 can be positioned and stopped at the loading / unloading position (e.g., the first loading / unloading port, the second loading / unloading port, and the third loading / unloading port) during its sliding motion on the track 1.

[0053] In one exemplary embodiment of this disclosure, reference is made to Figure 4The schematic diagram of track 1 shown includes a main track and a first branch track 14. The cable unloading area 11, cable prefabrication area 12, and wiring area 13 are sequentially connected on the main track. One end of the first branch track 14 is connected to the main track, while the other end is disconnected. A fourth loading / unloading port can also be provided on the protective netting 5 below the first branch track 14, allowing the conveyor trolley 3 to pass through the fourth loading / unloading port for lifting or lowering. For example, for a very small number of special cables that may not be suitable for wiring in the wiring area 13, these cables, after being prefabricated in the cable prefabrication area 12, can slide through track 1 to the first branch track 14 without entering the wiring area 13, thus allowing for special wiring in the area below the first branch track 14. Alternatively, the first branch track 14 can also be used for unloading and repairing faulty conveyor trolleys 3, enabling the aerial conveyor line to adapt to various special working conditions without affecting the normal logistics operation on the main track. In some exemplary embodiments, track 1 may include multiple first branch tracks 14, each of which is connected to the main track at one end and disconnected at the other end.

[0054] In one exemplary embodiment of this disclosure, track 1 may further include a second branch track, both ends of which are connected to the main track. The second branch track can be used to transfer the conveying tooling car 3 to alleviate congestion when there is congestion in the logistics operation on the main track or when the production rhythm corresponding to the cable unloading area 11, cable prefabrication area 12 and wiring area 13 is abnormal.

[0055] For example, track 1 may include a main track and a first branch track 14 but not a second branch track, or it may include a main track and a second branch track but not a first branch track 14, or it may include only the main track, or it may include the main track, the first branch track 14 and the second branch track at the same time.

[0056] For example, track 1 can be made of high-strength C-shaped bent plate, and the surface of track 1 is galvanized to improve the load-bearing strength and corrosion resistance of track 1. For example, track 1 is provided with 90° turnouts, and the fork tongues can be controlled by cylinders to switch different running routes on track 1, so as to realize the flexible steering of the conveying tooling car 3 and orderly conveying even on complex paths.

[0057] In one exemplary embodiment of this disclosure, reference is made to Figure 5The schematic diagram of the conveying fixture 3 shows that the cable receiving cavity 31 can be surrounded by a receiving cavity baffle 301, which surrounds the cable receiving cavity 31 at least in the bottom direction and the surrounding side walls of the conveying fixture 3. The cable receiving cavity 31 is used to receive cables to be processed. By storing and transporting large cables with a diameter of 10 square millimeters or more and small cables with a diameter of less than 10 square millimeters to the cable prefabrication area 12 through the cable receiving cavity 31, the storage and transportation efficiency can be improved.

[0058] refer to Figure 5 As shown, the first cable fixing part 32 and the second cable fixing part 33 are located at the end of the cable receiving cavity 31 away from the moving mechanism. For example, the conveying tooling vehicle 3 includes a first frame 34 and a second frame 35, which are parallel to the ground. The moving mechanism, the cable receiving cavity 31, the second frame 35, and the first frame 34 are arranged sequentially from bottom to top. Both the first frame 34 and the second frame 35 are rectangular frames and are parallel to the receiving cavity baffle 301 on the bottom surface of the cable receiving cavity 31. The first cable fixing part 32 is located on the side of the first frame 34, and the second cable fixing part 33 is located on the top surface of the second frame 35 away from the cable receiving cavity 31. The side surface referred to in this disclosure is the four sides adjacent to the bottom surface and perpendicular to the bottom surface. For example, the first cable fixing part 32 is located on one or both sides of the first frame 34 in the length direction, or the first cable fixing part 32 is located on all four sides of the first frame 34 in the length and width directions.

[0059] The second cable fixing part 33 is located on the top surface of the second frame 35 away from the cable receiving cavity 31. For example, the second cable fixing part 33 includes multiple support rods arranged in an array along the length direction of the second frame 35. The support rods are located on the top of the second frame 35. The finished template wire harness of the wiring area 13 can be placed on the support rods and moved away from the ground to the corresponding work position by the moving mechanism.

[0060] In one exemplary embodiment of this disclosure, the first cable fixing part 32 may be a hook extending from the first frame 34 in a second direction, as shown in the reference. Figure 5 , Figure 6 As shown, terminals are used for attaching prefabricated cables. Specifically, after the cables to be processed are assembled with terminals in the cable prefabrication area 12 to form prefabricated cables, they can be hung on the hooks of the first cable fixing part 32, with the other end hanging freely. Both the first frame 34 and the second frame 35 can be rectangular frames, and the long side of the first frame 34 is parallel to the long side of the second frame 35, and the short side of the first frame 34 is also parallel to the short side of the second frame 35. For example, the projections of the first frame 34 and the second frame 35 on the ground coincide. The first direction can be the direction of the long side of the first frame 34 (second frame 35), and the second direction can be the direction of the short side of the first frame 34 (second frame 35).

[0061] In one exemplary embodiment of this disclosure, the first cable fixing part 32 is disposed on the side of the first frame 34 along the first direction. Exemplarily, the first cable fixing part 32 may be symmetrically disposed on two sides of the first frame 34 in the first direction.

[0062] The second cable fixing part 33 includes a plurality of V-shaped rods 331 arranged in an array along the first direction, for reference. Figure 5 , Figure 7 As shown, the V-shaped rod 331 opens in the direction away from the cable receiving cavity 31, i.e., it opens upwards, so that the finished template wire harness can be placed on the side of the V-shaped rod 331 away from the cable receiving cavity 31. Specifically, the finished template wire harness has a complex structure and a large volume after wiring. Placing the finished template wire harness on the V-shaped rod 331 allows the finished template wire harness to bend upwards on both sides of the V-shaped rod 331 in the second direction, making it less likely to fall to the ground.

[0063] For example, the V-shaped rod 331 opens at an angle of not less than 150° in the direction away from the cable receiving cavity 31. That is, the opening angle of the V-shaped rod 331 is not less than 150° and less than 180°. For example, in one exemplary embodiment of this disclosure, the opening angle of the V-shaped rod 331 is 150°.

[0064] In one exemplary embodiment of this disclosure, both the first frame 34 and the second frame 35 are rectangular frames, and the long side of the first frame 34 is parallel to the long side of the second frame 35, and the short side of the first frame 34 is parallel to the short side of the second frame 35. The width of the first frame 34 along the second direction is greater than that of the second frame 35; for example, the projection of the second frame 35 onto the ground is inside the projection of the first frame 34 onto the ground. The V-shaped rod 331 extends out of the second frame 35 in the second direction, that is, the width of the V-shaped rod 331 in the second direction is greater than that of the short side of the second frame 35. Figure 7 As shown, the finished template wire harness can be placed on the V-shaped bar 331, and the ends of the cables can hang down from both sides of the V-shaped bar 331 in the second direction without being blocked by the second frame 35.

[0065] In an exemplary embodiment of this disclosure, the first cable fixing part 32 is disposed on the first frame 34, and the second cable fixing part 33 is disposed on the second frame 35. The first frame 34 is above the second frame 35, so that the finished template wire harness placed on the second cable fixing part 33 is less likely to come into contact with the first cable fixing part 32 and is less likely to be hooked or scratched.

[0066] In one exemplary embodiment of this disclosure, a support plate 36 is provided between the second frame 35 and the cable receiving cavity 31, and the support plate 36 is parallel to the ground. (See reference...) Figure 5As shown, the width of the support plate 36 along the second direction can be less than the width of the V-shaped bar 331 in the second direction. The support plate 36 can be used to support the ends of cables fixed to the first cable fixing part 32 or the second cable fixing part 33, such as the ends of prefabricated cables hooked on the first cable fixing part 32, or the ends of finished template wire bundles placed on the V-shaped bar 331 of the second cable fixing part 33.

[0067] According to another aspect of this disclosure, an overhead locomotive cable conveying system is also provided, including the overhead locomotive cable conveying device of any of the above-mentioned embodiments, and an electronic control system. The conveying tool 3 is equipped with an identification code, and a reader / writer is provided on the track 1 to read the identification code and monitor the position of the conveying tool 3; a drive device is provided on the track 1 to drive the conveying tool 3 to move on the track 1; the electronic control system is signal-connected to the reader / writer and the drive device, and is used to control and monitor the path of the conveying tool 3 on the track 1.

[0068] The locomotive cable overhead conveying system disclosed herein has a reasonable overhead conveying line layout. By making good use of the limited space on site, the cable unloading area 11, the cable prefabrication area 12 and the wiring area 13 are well integrated. The operation of the conveying tooling car 3 can be controlled and monitored by the electrical control system, thereby realizing the effective monitoring and control of the real-time position of various cables and realizing digital management and control of locomotive cables from unloading to prefabrication and wiring.

[0069] For example, the track 1 is equipped with a radio frequency identification (RFID) reader / writer for writing and reading the identification code information of the conveying tooling car 3, for power control system identification and judgment, and also for tracking the operation of the conveying tooling car 3 on the track 1.

[0070] In one exemplary embodiment of this disclosure, a read / write device is provided at least at the loading and unloading ports (e.g., the first, second, third, and fourth loading and unloading ports) to realize real-time reading and writing of the transport vehicle 3's operation tracking, providing real-time feedback on the transport vehicle's position and analyzing its operating status. Exemplarily, a 90° switch is provided on track 1, and a read / write device is also provided at the switch to realize real-time reading and writing of the transport vehicle 3's operating route. Exemplarily, the transport vehicle 3 is equipped with an identification code, which not only interacts with the read / write device on track 1 but is also used for information binding and identification with AGV vehicles when moving on the ground, facilitating intelligent scheduling and management of the logistics system and improving the transparency and controllability of the logistics process.

[0071] In one exemplary embodiment of this disclosure, after the wire harness production is completed, an overhead conveyor task list can be automatically generated based on the production work order issued by the upstream production management system. Operators or robots can scan the barcode on the hook at the second end of the lifting mechanism with a barcode scanner to automatically or manually select the process to which the hook should go, thus achieving precise scheduling and transportation of the wire harness.

[0072] For example, the electrical control system includes a PLC control module, with drive units, frequency converters, and other related equipment connected to the PROFINET bus. An industrial computer controls the production line via wired transmission, completing various actions of the production line. The host computer can monitor the production line status in real time. For example, the electrical control system includes a fault self-diagnosis module, which can perform logical performance judgments on its own hardware and prompt operators to perform qualitative testing or replacement of relevant components via a human-machine interface, audible and visual alarms, and wired communication to the host computer.

[0073] Other embodiments of this disclosure will readily occur to those skilled in the art upon consideration of the specification and practice of the invention disclosed herein.
