Description

Technical Field

[0001] This invention relates to the field of overhead contact line dropper processing, and specifically to a dropper fixed-length feeding device. Background Technology

[0002] With the rapid development of high-speed rail technology in my country, newer and higher requirements have been placed on railway process quality and standards. In electrified railway lines, the overhead contact system is a crucial component ensuring normal railway operation. The contact system is connected to the electrified railway power supply line, providing power to electric locomotives and their auxiliary equipment. In the contact system, the dropper is a key factor in ensuring good contact between the contact system and the locomotive's pantograph. Every 6-8 meters along the line, an integral dropper is installed to suspend the contact wire from the catenary cable, ensuring the suspension height of the contact wire and maintaining a certain degree of elasticity to guarantee good contact between the contact system and the pantograph. The dropper includes the dropper wire, a heart-shaped ring and clamping tube on one or both sides of the dropper wire, and wire lugs at one or both ends of the dropper wire. The production process of droppers mainly consists of several steps: wire cutting, threading, tensioning, crimping, marking, and bundling. Threading involves passing the dropper wire through the crimping tube, heart-shaped ring, and lug. Tensioning refers to using the dropper wire to tighten the heart-shaped ring and crimping tube. Crimping involves pressing the crimping tube and lug tightly against the dropper wire. Currently, dropper production is primarily manual, typically employing four to five people per shift to perform each of the aforementioned steps. This production method suffers from high labor costs and low precision in the finished droppers, particularly in the wire cutting and crimping stages. Manual production often results in inconsistent and uneven lengths, weak crimping, or excessive crimping force leading to cracking of the crimping tube and / or lug. During the wire feeding process, since the dropper wire is wound on the spool, manual unwinding and stretching are required. This is time-consuming and labor-intensive, and it cannot guarantee that the dropper wire is under tension, necessitating further tensioning during subsequent production. In the wire cutting process, the primary method is cutting, which involves manually cutting the drop wire using tools such as pliers. Manual cutting is inefficient and unsuitable for automated production. More importantly, it causes the drop wire to untangle at the cut point, hindering subsequent threading operations. This is particularly problematic when the drop wire passes through the clamping tube and / or into the wire lug, where the untangled strands at the end of the drop wire cause significant interference.

[0003] In view of this, the present invention aims to provide a fixed-length feeding device for drop wires, which uses multiple modular units to realize automatic feeding, correction and tensioning of drop wires, and uses heating, twisting and breaking to realize automatic cutting of the wires, and the drop wires form a frustoconical end at the cutting point, thereby solving the technical problem of unraveling at the cutting point of drop wires in the prior art and facilitating subsequent threading operations. Summary of the Invention

[0004] The present invention aims to provide a fixed-length feeding device for suspension cables to overcome the shortcomings of the prior art. The technical problem to be solved by the present invention is achieved through the following technical solution.

[0005] An improved dropper wire length feeding device includes a feeding module, a correction module, a conveying module, a cutting module, a feeding module, and a workbench. The feeding module is located on the side of the workbench and supports the dropper wire spool and feeds the wire to the correction module. The feeding driver of the feeding module operates synchronously with the conveying driver of the conveying module to keep the dropper wire taut. The dropper wire drawn from the spool passes through the rotating wheel on the correction module and enters the conveying guide of the conveying module, where it is conveyed forward to the cutting module. The conveying module continues to feed the dropper wire forward so that it enters the feeding guide of the feeding module. The conveying module and the feeding module jointly feed the dropper wire. After the dropper wire reaches the predetermined feeding length, the cutting module heats, twists, and breaks the dropper wire to complete the length cutting operation. The feeding module continues to feed the dropper wire forward to the next station of the dropper wire production line.

[0006] In this invention, the feeding module is used for unloading the wire, that is, placing the spool of the dropper wire on the feeding module and unloading it using a feeding driver and a conveying driver, and tensioning the unloaded dropper wire using the synchronous operation of the feeding driver and the conveying driver; the correction module is used to correct the dropper wire. The reason for correcting the dropper wire is that the dropper wire is wound on the spool and bends during unloading, while the dropper wire needed to make the dropper wire needs to be as straight and long as possible. The dropper wire needs to be as straight and long as possible because although the finished dropper wire can be slightly curved, it needs to be cut according to the length of the dropper wire during the production process, so the dropper wire needs to be basically straight; the conveying module is used for conveying the dropper wire to a fixed length. The wire feeding module calculates the length of the dropper wire to be conveyed based on the number of rotations of the conveying driver. When the conveyed dropper wire reaches the predetermined length, the conveying stops, and the wire cutting module on the dropper wire production line cuts the wire; the wire feeding module is used to transport the dropper wire to the next station of the dropper wire production line for production.

[0007] In this invention, the wire clamping part is used to clamp the suspension wire, thereby providing a fixed end for twisting and breaking the suspension wire; the wire breaking part is used to clamp the suspension wire and twist and break it; the wire power supply part is used to provide power for the heating of the suspension wire located between the wire clamping part and the wire breaking part.

[0008] In use, after the suspension wire passes through the wire cutting clamping part and the wire cutting break part, the wire cutting clamping movable block of the wire cutting clamping part presses the suspension wire to clamp and fix one end of it; the wire cutting break chuck of the wire cutting break part clamps the other end of the suspension wire under the action of the wire cutting break clamping cylinder; the wire cutting power supply part, the wire cutting power supply copper plate A, the wire cutting clamping part, the suspension wire located between the wire cutting clamping part and the wire cutting break part, the wire cutting break part, and the wire cutting power supply copper plate B form a circuit, and the wire cutting power supply part starts to supply power; the cross-sectional area of ​​the suspension wire located between the wire cutting clamping part and the wire cutting break part is the smallest in the entire circuit. According to the principle that the smaller the cross-sectional area of ​​the conductor, the greater the resistance, and Joule's law Q=I 2 Rt, the dropper wire located between the wire clamping part and the wire breakage part generates the most heat, causing the dropper wire at this location to soften due to heat; the wire breakage driver of the wire breakage part drives the wire breakage chuck to rotate to twist the dropper wire located between the wire clamping part and the wire breakage part. After twisting is completed, the wire breakage cylinder fixed on the wire mounting base pushes the wire breakage part away from the wire clamping part to break the dropper wire, thereby completing the wire cutting operation.

[0009] Compared with existing technologies, this invention utilizes a feeding module and a conveying module for automatic feeding and tensioning of the drop wire, a correction module for correcting the drop wire, and a wire delivery module for conveying the drop wire to the next workstation. This invention enables automatic feeding, correction, and tensioning of the drop wire. The drop wire cut using this invention forms a frustoconical end at the cut point, preventing unraveling and facilitating subsequent threading operations. Attached Figure Description

Detailed Implementation

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] Example 1:

[0026] Reference Figures 1-13 As shown, an improved suspension wire fixed-length feeding device includes a feeding module 10, a correction module 20, a conveying module 30, a wire cutting module 60, a wire feeding module 40, and a workbench 50. The feeding module 10 is located on the side of the workbench 50. The feeding module 10 supports the suspension wire reel and feeds the wire to the correction module 20. The feeding driver 15 of the feeding module 10 operates synchronously with the conveying driver 32 of the conveying module 30 to keep the suspension wire taut. The suspension wire drawn from the reel passes through the rotating part of the correction module 20. After passing through the conveyor, the wire enters the conveyor guide 33 of the conveyor module 30 and is conveyed forward by the conveyor module 30 into the wire cutting module 60. The conveyor module 30 continues to convey the drop wire forward so that it enters the wire feeding guide 42 of the wire feeding module 40. The conveyor module 30 and the wire feeding module 40 jointly convey the drop wire. After the drop wire reaches the predetermined length, the wire cutting module 60 heats, twists, and breaks the drop wire to complete the fixed-length wire cutting operation. The wire feeding module 40 continues to convey the drop wire forward into the next station of the drop wire production line.

[0027] In this embodiment, the feeding module 10 is used for feeding the wire, that is, placing the spool of the dropper wire on the feeding module 10 and feeding it using the feeding driver 15 and the conveying driver 32, and tensioning the fed dropper wire by synchronously operating the feeding driver 15 and the conveying driver 32; the correction module 20 is used to correct the dropper wire. The reason for correcting the dropper wire is that the dropper wire is wound on the spool and bends during feeding, while the dropper wire needed to make the dropper wire needs to be as straight and long as possible. The length is important because although the finished dropper wire can be slightly curved, the wire needs to be cut according to its length during production, so the dropper wire needs to be basically straight. The conveying module 30 is used to convey the dropper wire to a fixed length. The conveying module 30 calculates the length of the conveyed dropper wire based on the number of rotations of the conveying driver 32. When the conveyed dropper wire reaches the predetermined length, the conveying stops, and the wire cutting module on the dropper wire production line cuts the wire. The wire feeding module 40 is used to convey the dropper wire to the next station on the dropper wire production line for further production.

[0028] In this embodiment, the feeding module 10 and the conveying module 30 are used for automatic feeding and tensioning of the drop wire, the calibration module 20 is used to calibrate the drop wire, and the wire delivery module 40 is used to transport the drop wire to the next station. Compared with the prior art, this embodiment can realize automatic feeding, calibration and tensioning of the drop wire.

[0029] In this embodiment, the wire cutting module 60 is installed on the workbench 50 and located between the conveying module 30 and the wire feeding module 40. The spool of the dropper wire is fed by the feeding module 10, the alignment module 20 aligns the dropper wire, and the conveying module 30 conveys the dropper wire. After the dropper wire conveyed by the conveying module 30 reaches the predetermined length, this embodiment performs a twisting and melting cutting operation. After the cutting operation is completed, the wire feeding module 40 conveys the cut dropper wire to the next station for subsequent operations. By using the wire cutting module 60 to heat, twist, and break the dropper wire to complete the fixed-length cutting operation, a frustum-shaped end can be formed at the cut point of the dropper wire, preventing unraveling and facilitating subsequent threading operations.

[0030] Example 2:

[0031] Based on Example 1, referring to Figure 1 As shown, the feeding module 10 includes a feeding support base plate 11, feeding support side plates A121 and B122 disposed at both ends of the feeding support base plate 11, and feeding rotating shafts A161 and B162 respectively disposed on the upper ends of the feeding support side plates A121 and B122 and correspondingly disposed thereon. The spool of the suspension wire is placed between the feeding rotating shafts A161 and B162.

[0032] Furthermore, a feeding mounting plate A131 is provided on the surface of the feeding support side plate A121 opposite to the feeding support side plate B122. A feeding reducer 14 is mounted on the feeding mounting plate A131. The output shaft of the feeding reducer 14 is connected to the feeding rotating shaft A161. The feeding reducer 14 is connected to the feeding driver 15.

[0033] Furthermore, a loading mounting plate B132 is provided on the surface of the loading support side plate B122 opposite to the loading support side plate A121. The loading mounting plate B132 is provided with a loading chuck 17 for clamping the transverse rod of the loading shaft B162. The transverse rod is used to adjust the lateral distance of the loading shaft B162 relative to the loading shaft A161.

[0034] Furthermore, a loading chuck wrench 171 is screwed onto the loading chuck 17. By rotating the loading chuck wrench 171, the loading chuck 17 clamps or releases the transverse rod of the loading shaft B162, thereby fixing or adjusting the lateral distance of the loading shaft B162 relative to the loading shaft A161.

[0035] Furthermore, the end of the transverse rod of the feeding shaft B162 is provided with a feeding handwheel 18. The transverse rod is moved laterally by the feeding handwheel 18 to adjust the lateral distance of the feeding shaft B162 relative to the feeding shaft A161.

[0036] Furthermore, the feeding handwheel 18 is rotatably provided with a feeding handwheel handle 181, which can be pulled out and pulled in relative to the feeding handwheel 18.

[0037] Furthermore, the end of the feeding shaft A161 is provided with a feeding shaft A clamping plate 1611, which is used to clamp the coil of the suspension wire.

[0038] Furthermore, the end of the feeding shaft B162 is provided with a feeding shaft B protrusion 1621, which is used to hold the coil of the suspension wire.

[0039] This embodiment provides a preferred implementation of the feeding module 10. The feeding support base plate 11 is used to support the entire feeding module 10 and can be placed at a suitable position on the side of the workbench 50 during use. The feeding support side plate A121 and feeding support side plate B122 are used to support the wire reel of the dropper and other components in the feeding module 10. The feeding reducer 14 and feeding driver 15 are used to provide power for feeding the wire reel of the dropper.

[0040] It is worth noting that the wire feeding is performed through the feeding driver 15 and the feeding reducer 14, rather than solely by the conveyor driver 32 of the rear conveyor module 30. This reduces the load and power of the conveyor driver 32 itself, preventing excessive load due to friction during the feeding process. It also lowers the required rated power of the conveyor driver 32, allowing for the selection of a lower-powered driver. Furthermore, the combination of the feeding driver 15 and the feeding reducer 14 with the conveyor driver 32 ensures continuous and stable wire feeding, utilizing the feeding process of the feeding driver 15 and the feeding reducer 14. The "release" and "pull" actions of the conveyor driver 32 during the conveying process ensure continuous stability of the feeding process. More importantly, the feeding driver 15 and the feeding reducer 14, in conjunction with the conveyor driver 32, achieve simultaneous release and tensioning of the dropper wire. That is, the stable rotation speed of the feeding driver 15 and the feeding reducer 14 during the release process prevents the dropper wire from being slack due to the inertia generated by the pull of the conveyor driver 32. In other words, the "reverse pull" of the feeding driver 15 and the feeding reducer 14, combined with the "forward pull" of the conveyor driver 32, achieves simultaneous release and tensioning of the wire, thereby effectively correcting the dropper wire in conjunction with the correction module 20.

The suspension wire is calibrated by passing through the calibration mounting strip roller 231 and the calibration mounting plate roller 24.

[0043] Furthermore, the end of the calibration mounting strip 23 is also provided with a calibration mounting strip adjustment plate 232. By adjusting the position of the calibration mounting strip adjustment plate 232 relative to the calibration mounting strip 23, the distance between the calibration mounting strip wheel 231 and the calibration mounting strip adjustment plate 232 can be adjusted to accommodate suspension wires of different thicknesses.

[0044] Furthermore, an adjustment plate slot 2321 is provided at the position where the adjustment plate 232 connects to the adjustment plate 23, and the position of the adjustment plate 232 relative to the adjustment plate 23 is adjusted through the adjustment plate slot 2321.

[0045] Furthermore, the calibration mounting strip 23 is connected to the calibration mounting plate 22 via the calibration mounting strip pivot 233.

[0052] Furthermore, the correction mounting plate 22 is provided with correction mounting plate stiffeners 224 for enhancing the support strength of the correction mounting plate 22.

The distance between the corrective mounting strip adjustment plate 232 and the corrective mounting strip wheel 231 can also be adjusted as needed to accommodate dropper wires with different curvature and thickness.

[0065] Example 6:

[0066] Based on any of the foregoing embodiments, refer to Figures 7 to 13 As shown, the wire cutting module 60 includes a wire cutting mounting base 63, a wire cutting clamping part 61 and a wire cutting break part 62 disposed on the wire cutting mounting base 63, and a wire cutting power supply part 64 electrically connected to the wire cutting clamping part 61 and the wire cutting break part 62 via wire cutting power copper plates A 641 and B 642 respectively.

After the suspension wire passes through the wire cutting clamping part 61, it is clamped by the wire cutting clamping movable block 613 of the wire cutting clamping part 61. After the suspension wire passes through the wire cutting break chuck 623 of the wire cutting break part 62, the wire cutting break clamping cylinder 6221 pulls the wire cutting break chuck 623 to clamp the suspension wire. The wire cutting power supply part 64... A circuit is formed by the wire cutting power supply copper plate A641, the wire cutting clamping part 61, the suspension wire located between the wire cutting clamping part 61 and the wire cutting break part 62, the wire cutting break part 62, and the wire cutting power supply copper plate B642.
