AI Technical Summary
When existing train coupler equipment is in operation, the power cable and network cable are prone to kinking and pulling, which affects the movement accuracy of the equipment, leading to inaccurate coupler alignment and even equipment failure, thus failing to meet the high-efficiency and safe operation requirements of tipplers.
The dual-cable guide rod design separates the power cable from the network cable, allowing for free retraction via spring wires. Combined with an isolation plate and dustproof sealing ring, it prevents cable tangling. The gear and rack drive and eccentric wheel locking mechanism enable precise positioning and stable movement of the equipment. Pressure sensors and limit switches provide millimeter-level precision control of the coupler.
This effectively avoids cable kinking and tangling, ensuring the stability and accuracy of equipment operation, reducing the risk of coupler positioning deviation and equipment failure, and improving the safety and efficiency of rollover operations.

Abstract
Description
Technical Field
[0001] This invention relates to the field of train coupler equipment technology, specifically a train coupler equipment with double cable guide rods. Background Technology
[0002] In railway freight systems, tippers are key equipment for efficient unloading of wagons. During operation, the coupler needs to be fixed and aligned using a hook-up device to prevent the coupler from shifting due to gravity or inertia, ensuring precise docking between the wagon and the tipper and the safety of subsequent hook-up operations. The stable operation of the hook-up device directly affects the tipper's operating efficiency and safety. The orderly management of the power and network cables connected to the device is a crucial prerequisite for ensuring the precise movement of its motion mechanisms (such as hook-up device movement, upper wagon tilting, and coupler push plate positioning).
[0003] The applicant discovered through a search that a Chinese patent discloses a "coupling device" with application number "202323531427.8". This patent mainly adjusts the position of the coupling baffle through an adjustment mechanism to adapt to train couplers of different widths, solving the correction problem of couplers for various train models and improving the adaptability of the car tipper. However, this device does not involve the design of a cable management structure. In existing similar coupling equipment, the power cable and network cable are prone to kinking and pulling as the equipment moves and the mechanism flips during operation. This not only shortens the service life of the cables but may also interfere with the motion accuracy of the coupling equipment, leading to inaccurate coupler alignment and even equipment failure. This cannot meet the requirements of efficient and safe operation of the tipper. Therefore, we propose a train coupling device with double cable guide rods. Summary of the Invention
[0004] The purpose of this invention is to provide a train coupler device with dual cable guide rods.
[0005] To achieve the above objectives, the present invention provides the following technical solution: a train coupler device with double cable guide rods, comprising a tipper, a train car mounted on the tipper platform, with couplers connected to both ends of the train car, two coupler devices mounted at both ends of the tipper platform, the coupler devices located below the train car, running tracks connected to the left and right sides of the coupler devices, one end of a cable guide rod connected to the outer side of the coupler device, the other end of the cable guide rod connected to a guide rod housing, the ends of the two cable guide rods near the guide rod housing connected to a cable junction box, the spring wire electrically connected to the inside of the coupler device through the guide rod 5, the guide rod housing connected to the tipper platform via a base, an upper housing rotatably connected to the side of the coupler device body away from the cable guide rod, and a coupler push plate connected to the top of the upper housing.
[0006] As a further embodiment of the present invention: an eccentric wheel locking mechanism is provided below the positive hook device, the eccentric wheel locking mechanism being composed of an eccentric wheel, a guide wheel, an eccentric wheel shaft, a locking screw, and a rotating hole.
[0007] As a further embodiment of the present invention: the coupler push plate is composed of a fixed base, a contact plate, a rotating shaft, a limit shaft, a built-in pressure sensor, an internal spring, and a limit switch.
[0008] As a further aspect of the present invention: multiple isolation plates are connected to the side of the two cable guide rods that are close to each other.
[0009] As a further aspect of the present invention: a dustproof sealing ring is provided on the side of the two cable guide rods that is close to the guide rod housing.
[0010] As a further aspect of the present invention: the upper housing is connected to the hook device via a hinge shaft, and one side of the upper housing is connected to the drive end of a motor via a rotating rod, the motor being connected to the inside side of the hook device body.
[0011] As a further embodiment of the present invention: a guide wheel is provided at the middle of both the front and rear sides of the main body of the positive hook device, and the guide wheel is located inside the running track.
[0012] As a further aspect of the present invention: a mobile drive motor is fixedly installed inside the hook device, and a drive gear is fixedly connected to the output end of the mobile drive motor. A rack adapted to the drive gear is fixedly connected to the top of the tipper platform, and the drive gear meshes with the rack. The outer rings of the guide wheels on the left and right sides of the hook device are in contact with the inner sidewall of the running track, and the guide wheels roll along the inner side of the track as the hook device moves. The mobile drive motor drives the drive gear to rotate, and the drive gear moves along the length direction of the rack, driving the hook device to move synchronously. The guide wheels restrict the offset of the hook device in the vertical direction of the track.
[0013] As a further aspect of the present invention: the built-in pressure sensor and limit switch of the coupler push plate are both electrically connected to the push plate drive motor through wires; when the contact plate contacts the coupler, the contact plate rotates around the axis inside the coupler push plate and compresses the internal spring. The spring deformation causes the pressure sensor to collect contact pressure data in real time, and at the same time, the side wall of the contact plate triggers the limit switch; when the pressure data reaches a preset threshold or the limit switch is triggered, the push plate drive motor immediately stops running, and the coupler push plate stops moving in the coupler direction.
[0014] As a further embodiment of the present invention: the isolation plates are distributed at intervals along the length of the cable guide rods, with a spacing of 15-20cm between adjacent isolation plates. The two ends of each isolation plate are fixedly connected to the sides of the two cable guide rods that are close to each other. The isolation plates are perpendicular to the axis of the cable guide rods, dividing the space between the two cable guide rods into independent channels. The power cable passes through one of the independent channels, and the network cable passes through the other independent channel. The isolation plates prevent the two cables from contacting or tangling with each other during the movement of the equipment.
[0015] As a further aspect of the present invention: the output end of the tilting motor of the upper housing is fixedly connected to the rotating rod, and the end of the rotating rod away from the motor is fixedly connected to the hinge shaft. The tilting motor has a built-in electromagnetic brake mechanism, and the brake pad of the electromagnetic brake mechanism corresponds to the outer surface of the rotating rod. When the upper housing tilts around the hinge shaft to be perpendicular to the main body of the hook device, the electromagnetic brake mechanism is energized, the brake pad clamps the rotating rod, and restricts the rotation of the rotating rod. When the upper housing needs to be reset, the electromagnetic brake mechanism is de-energized, the brake pad disengages from the rotating rod, and the tilting motor drives the rotating rod to rotate in the opposite direction, so that the upper housing falls back around the hinge shaft to be parallel to the tipper platform.
[0016] Compared with the prior art, the beneficial effects of the present invention by adopting the above technical solution are as follows:
[0017] 1. This invention separates the power cable and network cable using dual cable guide rods, and allows for free retraction with spring wires. This effectively prevents cables from twisting when the equipment moves or the upper housing is flipped, solving the problem of chaotic cable layout in traditional equipment. At the same time, the orderly guidance of the cables by the dual cable guide rods prevents cables from pulling or tangling and interfering with the movement of the hook equipment, the 90-degree flip of the upper housing, and the positioning of the coupler push plate. This ensures the precise operation of each mechanism, improves the overall stability of the hook equipment, avoids coupler positioning deviation due to cable problems, reduces the risk of coupler damage or equipment failure during tipping, and further ensures operational safety.
[0018] 2. This invention employs a gear and rack drive combined with an eccentric wheel locking design. By adjusting the eccentric wheel to press against the back of the rack, precise three-point positioning is achieved during the movement of the hooking device, eliminating the swaying problem caused by track deviation and improving movement stability. A rotatable contact plate and a built-in limit switch are set at the front end of the coupler push plate. The contact plate triggers a signal to the coupler, providing real-time feedback on the push plate position, achieving millimeter-level contact precision control and preventing coupler damage. The PLC integrates control of the gear and rack moving motor, the tilting motor, and the push plate motor. Combined with encoder angle feedback and limit switch position signals, the entire hooking operation process is automated and precisely controlled. Attached Figure Description

[0024] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand the present invention, but does not constitute a limitation of the present invention.
[0025] Furthermore, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0026] Please see the appendix Figure 1 -Appendix Figure 4 This invention discloses a train coupler device with double cable guide rods, comprising a tipper platform 1, a tipper 9, a train carriage 2 inside the tipper 9, and couplers 10 connected to both sides of the train carriage 2. Two couplers 3 are installed on the top of the tipper platform 1, located below the train carriage 2. Running tracks 4 are connected to both sides of the couplers 3. A cable guide rod 6 is connected to one side of the couplers 3. The cable guide rod 6 is connected to a guide rod housing 5. The inside of the two cable guide rods 6 is a spring wire channel. The other end of the spring wire is connected to a junction box at one end of the guide rod housing 5. The guide rod housing 5 is connected to the tipper platform 1 through a base. An upper housing 7 is rotatably connected to the side of the couplers 3 away from the cable guide rod 6. A coupler push plate 8 is connected to one side of the end of the upper housing 7.
[0027] In Example 1, an eccentric wheel locking mechanism is provided below the hook device 3. The eccentric wheel locking mechanism consists of an eccentric wheel, a guide wheel, an eccentric wheel shaft, a locking screw, and a rotating hole. The coupler push plate 8 consists of a fixed seat, a contact plate, a rotating shaft, a limit shaft, a built-in pressure sensor, an internal spring, and a limit switch. The upper housing 7 is connected to the hook device 3 via a hinge shaft. One side of the upper housing 7 is connected to the drive end of a motor via a rotating rod. The motor is connected to the inside of the hook device 3 body. Guide wheels are provided at the middle of the front and rear sides of the hook device 3. The guide wheels are located inside the running track 4.
[0028] Specifically, the hook device 3 is driven by a motor to move a gear and rack, causing the hook device to move along the track direction. The gear and rack provide the motion, and the two guide wheels enable the hook device to move in a straight line. The guide wheels are pressed together by an eccentric wheel mechanism to prevent the hook device from shaking or deviating during movement. The eccentric wheel locking mechanism consists of an eccentric wheel, a guide wheel, an eccentric wheel shaft, and locking screws. When the eccentric wheel is rotated through the two rotating holes on the eccentric wheel with a special tool, the guide wheel will rotate eccentrically. After the guide wheel is pressed against the back of the rack of the object being touched, the two locking screws on the top are tightened to lock it. The coupler push plate 8 consists of a fixed seat, a contact plate, a rotating shaft, a limit shaft, and internal springs and limit switches. When the contact plate touches the coupler 10, it activates the internal limit switch, causing the push plate to stop moving. The contact plate rotates around the rotating shaft. The upper limit hole is an oblong hole, which allows the push plate to move left and right within a certain range to touch the limit switch or move away through the limit shaft.
[0029] In embodiment 2, multiple isolation plates are connected to the side of the two cable guide rods 6 that are close to each other, and a dustproof sealing ring is provided on the side of the two cable guide rods 6 that is close to the guide rod housing 5;
[0030] Specifically, two sets of parallel cable guide rods 6 are used to guide the power cable and signal cable respectively. The guide rods are designed to be telescopic, with spring wires connected to the ends to adapt to length changes when the equipment moves. An isolation plate is installed between the two cable guide rods 6 to prevent the cables from getting tangled, and a dustproof sealing ring is used to prevent dust from entering.
[0031] In this invention, the isolation plates are distributed at intervals along the length of the cable guide rods 6, with a spacing of 15-20cm between adjacent isolation plates. The two ends of each isolation plate are fixedly connected to the sides of the two cable guide rods 6 that are close to each other. The isolation plates are perpendicular to the axis of the cable guide rods 6, dividing the space between the two cable guide rods 6 into independent channels. The power cable passes through one of the independent channels, and the network cable passes through the other independent channel. The isolation plates prevent the two cables from contacting or tangling with each other during the movement of the equipment.
[0032] In this invention, the built-in pressure sensor and limit switch of the coupler push plate 8 are electrically connected to the push plate drive motor through wires. When the contact plate contacts the coupler 10, the contact plate rotates around the axis inside the coupler push plate 8 and compresses the internal spring. The spring deformation causes the pressure sensor to collect contact pressure data in real time, and at the same time, the side wall of the contact plate triggers the limit switch. When the pressure data reaches the preset threshold (0.8-1.2MPa) or the limit switch is triggered, the push plate drive motor immediately stops running, and the coupler push plate 8 stops moving towards the coupler 10.
[0033] In this invention, a mobile drive motor is fixedly installed inside the main body of the hook device 3. The output end of the mobile drive motor is fixedly connected to a drive gear. A rack adapted to the drive gear is fixedly connected to the top of the tipper platform 1. The drive gear meshes with the rack. The outer rings of the guide wheels on the front and rear sides of the hook device 3 are in contact with the inner sidewall of the running track 4. The guide wheels roll along the inner side of the track as the hook device 3 moves. The mobile drive motor drives the drive gear to rotate. The drive gear moves along the length direction of the rack, driving the hook device 3 to move synchronously. The guide wheels restrict the offset of the hook device 3 in the vertical direction of the track.
[0034] In this invention, the output end of the tilting motor of the upper housing 7 is fixedly connected to the rotating rod, and the end of the rotating rod away from the motor is fixedly connected to the hinge shaft. The tilting motor has a built-in electromagnetic brake mechanism, and the brake pad of the electromagnetic brake mechanism corresponds to the outer surface of the rotating rod. When the upper housing 7 tilts around the hinge shaft to be perpendicular to the hook device 3, the electromagnetic brake mechanism is energized, the brake pad clamps the rotating rod, and restricts the rotation of the rotating rod. When the upper housing 7 needs to be reset, the electromagnetic brake mechanism is de-energized, the brake pad disengages from the rotating rod, and the tilting motor drives the rotating rod to rotate in the opposite direction, so that the upper housing 7 falls back around the hinge shaft to be parallel to the tipper platform.
[0035] Working principle:
[0036] Preparation stage: The equipment is in a non-working state, the upper box 7 is lying flat, and the whole is located on the inner end of the track. There are two sets of positive hook equipment, which are installed at appropriate positions at both ends of the tipper platform 1. The two positive hooks are mirror images of each other. The positive hook coupler push plates 8 are arranged on the tipping gravity side to fix and straighten the front and rear couplers 10 of the train car 2 to prevent the couplers 10 from shifting due to gravity during the tipping process. The main moving mechanism of the positive hook equipment is the positive hook equipment 3, which moves in the parallel direction of the track, the upper box 7, which is hinged to the body of the positive hook equipment 3 and can be rotated 90 degrees, the coupler push plate 8 on the top of the upper box 7, which can move in the vertical direction of the track, as well as the positive hook running track 4, cable guide rod 6 and other mechanisms.
[0037] Moving phase: The third motor of the hook device starts, driving the device to move to the outer end of the track;
[0038] Tilting Stage: When hook support is needed during the tipping process, the hook device 3 is driven by a motor through a gear and rack mechanism to move the entire box towards the end of the tipper 9 along the hook track. After reaching the end of the hook track, the upper box 7 is driven by a motor to rotate 90 degrees, perpendicular to the hook device 3. The tilting motor is then locked by a brake, keeping the upper box 7 in a 90-degree position. At this time, the hook device 3 moves in the opposite direction towards the middle of the tipper platform 1. When the hook contact rod touches the hook 10, the limit switch senses that the hook has moved to the hook 10 position, and the hook device 3 stops moving. Then, the hook push plate 8 is driven by a motor to move towards the hook 10. When the push plate contact plate at the front end of the push plate touches the hook 10, the sensor inside the push plate senses that the push plate has supported the hook 10, the push plate stops moving, and the push plate motor locks. At this point, the tipping can proceed normally.
[0039] Reset Phase: After the tipping is completed, the push plate retracts, the upper box 7 is leveled, and the equipment returns to its initial position, that is, the tipping machine 9 returns to the center and stops tipping—the coupler push plate 8 reverses the coupler 10 and moves to the farthest position to disengage the coupler 10—the push plate motor locks—the upper box 7 tipping plate resets to 0 degrees—the upper box 7 tipping plate motor locks—the positive hook device 3 drives the positive hook device to move to the stationary original point—all motors are de-energized and locked;
[0040] During this process, when the equipment moves, the double cable guide rod 6 guides the cable to extend and retract in an orderly manner, the spring wire provides elastic compensation to keep the cable tension moderate, the isolation design avoids signal interference, the encoder monitors the flip angle of the upper housing 7 in real time, the limit switch and pressure sensor provide dual position feedback, and the PLC control system coordinates the actions of each motor.
[0041] The hook device 3 is driven by a motor to move a gear and rack, which in turn moves the hook device along the track. The gear and rack provide the motion, and the two guide wheels enable the hook device to move in a straight line. The guide wheels are pressed together by an eccentric wheel mechanism to prevent the hook device from shaking or deviating during movement. The eccentric wheel locking mechanism consists of an eccentric wheel, a guide wheel, an eccentric wheel shaft, and locking screws. When the eccentric wheel is rotated through the two rotating holes on the eccentric wheel with a special tool, the guide wheel will rotate eccentrically. After the guide wheel is pressed against the back of the rack of the object being touched, the two locking screws on the top are tightened to lock it. The coupler push plate 8 consists of a fixed seat, a contact plate, a rotating shaft, a limit shaft, and internal springs and limit switches. When the contact plate touches the coupler 10, it activates the internal limit switch, causing the push plate to stop moving. The contact plate rotates around the rotating shaft. The upper limit hole is an oblong hole. Through the limit shaft, the push plate can move left and right within a certain range to touch the limit switch or move away. At this point, the entire working process is completed.
