[0002] In the fields of mining transportation and rail transportation, automatic uncoupling and coupling control technology for electric locomotives and passenger cars is a key link in ensuring transportation efficiency and safety. The traditional manual uncoupling and coupling method is not only inefficient, but also has high safety risks and cannot meet the needs of modern and large-scale transportation. Therefore, the automatic uncoupling and coupling control system came into being. It realizes the autonomous connection and separation of electric locomotives and passenger cars through the combination of mechanical structure, sensors and intelligent control technology, significantly improving transportation efficiency and safety, and is increasingly widely used in scenarios such as mines and underground operations.

[0003] In terms of mechanical connection, the existing automatic hooking and unhooking control system for electric locomotives faces working conditions such as track laying errors and mine car position offsets, making it difficult to accurately align the hooking and unhooking components, resulting in connection failure or loose connections; in terms of shock absorption and buffering, the impact generated during the connection process can easily cause component wear and deformation, shortening the service life of the equipment; in terms of positioning control, there is a lack of efficient and accurate positioning means, making it difficult to adapt to complex and changing working environments, resulting in low hooking and unhooking efficiency; these problems seriously restrict the reliability and stability of the automatic hooking and unhooking system.

Before the connecting, the angle between the traction pin 4 and the connecting unit is adjusted by the angle control units provided on the upper and lower sides of the rotating frame 6, so that the connecting unit and the traction pin 4 can be kept on the same horizontal line.

Under the action of the output shaft of the adjusting motor 14 to rotate the adjusting screw 13, the two sliding guide blocks are allowed to move relative to or back to each other in the movable groove 12. Displacement; Both sides of the top of the buffer frame 10 are fixedly provided with a picking and hanging limit part 15, and the bottoms of the two picking and hanging limit parts 15 are respectively fixedly connected to the tops of the two sliding guide blocks, and the opposite sides of the two picking and hanging limit parts 15 are provided with a connecting groove that cooperates with the traction pin 4, and the inside of the two connecting grooves are fixedly provided with a deformation limit frame 16, wherein the deformation limit frame 16 is made of shape memory alloy, and a microelectronic control unit for controlling the deformation of the deformation limit frame 16 is provided inside the two picking and hanging limit parts 15.

[0039] Specifically, the shape memory alloy used by the deformation limiting frame 16 is nickel-titanium alloy.

[0040] It should be noted that when controlling the hooking between the hooking unit and the traction pin 4, one side of the traction pin 4 is sent into the hooking inner cavity 9 inside the hooking frame 8, and one end of the traction pin 4 contacts one side of the buffer frame 10. For the connection impact between the electric locomotive traction part 1 and the passenger car connection part 2, the butterfly spring 11 arranged at the top and bottom of the buffer frame 10 cooperates with the damper arranged therein to effectively buffer and release the impact force during the connection, thereby avoiding damage caused by rigid collision when the traction pin 4 and the hooking frame 8 are connected; then, the output shaft of the motor 14 is adjusted to control the two hooking limit parts 15 to move toward the traction The surfaces of the guide pins 4 are close to each other, and the connecting grooves inside the two picking and hanging limit parts 15 respectively cover the two sides of the surface of the traction pin 4.

The adjustment motor 14 drives the adjustment screw 13, so that the sliding guide block drives the unhooking limit part 15 to move and accurately cover the traction pin 4. The deformation limit frame 16 made of shape memory alloy deforms under the action of the microelectronic control unit, and after cooling, it firmly hooks the traction pin 4 together with the unhooking limit part 15 to ensure the stability of the connection. In addition, the fixed seat 3 and the traction pin 4 are cast as one piece, which enhances the structural strength of the passenger car connection part 2 and lays the foundation for reliable connection.

[0042] Example 2

[0043] Specifically, the present embodiment discloses the structural composition of the angle control unit, which includes a connecting frame 17, an angle adjustment frame 26 and an angle control plate 31. The upper and lower sides of one side of the rotating frame 6 are fixed with connecting frames 17 by bolts, and one side of the two connecting frames 17 is provided with a connecting slide; connecting sliders 18 are slidably provided on both sides of the connecting slide, and one side of the two connecting sliders 18 is fixedly provided with a rotating pin 19, and the surfaces of the two rotating pins 19 are rotatably provided with a rotating connecting block 20, and one side of the two rotating connecting blocks 20 is fixedly provided with a connecting rod 1 21, one end of the two connecting rods 11 is slidably provided with a connecting rod 2 22, and one end of the two connecting rods 22 is fixedly provided with a rotating connecting block 24, the rotating connecting A connecting rod 22 is fixedly provided between block 1 20 and the side opposite to the rotating connecting block 2 24, and the connecting rod 22 is sleeved on the surface of the connecting rod 1 21 and the buffer spring 23; a rotating pin 25 is rotatably provided on the side opposite to the two rotating connecting blocks 24, and a mounting plate 27 is rotatably provided on the upper and lower ends of the two rotating pins 25, an angle adjustment frame 26 is fixed between the upper and lower mounting plates 27 by bolts, and a buffer plate 29 is movably provided on one side of the angle adjustment frame 26, four butterfly springs 28 are fixedly provided inside the angle adjustment frame 26, and one end of the four butterfly springs 28 is fixedly connected to one side of the buffer plate 29, wherein the four butterfly springs 28 are also internally provided with a damper for buffering and releasing the impact received by the buffer plate 29.

[0044] Specifically, butterfly spring 11 and butterfly spring 2 28 are both made of 50CrVA spring steel; the rotating shaft 7 is matched with the connecting seat 5 with an H7 / g6 clearance fit, and with the rotating frame 6 with an interference fit, with an interference amount of 30 mm, to ensure that the rotating frame 6 can rotate flexibly and position accurately; when the servo linear slide 32 is installed, the straightness error of its guide rail does not exceed 30 mm / m, and the flatness error of the installation plane does not exceed 20 mm, to ensure the sliding accuracy of the positioning slider 33.

[0045] Furthermore, two angle-controlling servo electric cylinders 30 are fixedly provided on one side inside the angle-controlling frame 26, and angle-controlling plates 31 are fixedly provided on the top ends of the driving shafts of the two angle-controlling servo electric cylinders 30. The driving shaft of the angle-controlling servo electric cylinder 30 inside the lower angle-controlling frame 26 is used to control the angle-controlling plate 31 to approach the bottom end of the traction pin 4, and the driving shaft of the angle-controlling servo electric cylinder 30 inside the upper angle-controlling frame 26 is used to control the angle-controlling plate 31 to approach the top end of the traction pin 4. After the horizontal angle of the passenger-car connection part 2 is offset, the upper and lower ends of the traction pin 4 are clamped respectively by the upper and lower angle-controlling plates 31. At this time, the rotating frame 6 rotates, so that the hanging and unhanging frame 8 and the traction pin 4 between the upper and lower angle-controlling frames 26 are in a horizontal state, so as to facilitate the subsequent rapid and accurate hanging and unhanging between the hanging and unhanging frame 8 and the traction pin 4.

[0046] In a specific embodiment, the present invention effectively improves the adaptability and accuracy of automatic unhooking of the electric locomotive through the coordinated operation of multiple components. The sliding structure composed of the connecting frame 17 and the connecting slider 18, together with the retractable rotating assembly composed of a rotating pin shaft 19, a rotating connecting block 20, a connecting rod 21, a connecting rod 22 and a buffer spring 23, enables the angle control unit to have flexible displacement and angle adjustment capabilities, and can adapt to the horizontal offset of the passenger car connection part 2; the butterfly spring 28 in the angle adjustment frame 26 cooperates with the damper to buffer the impact force when the traction pin 4 is connected to the unhooking frame 8, protect the components and improve the connection stability; the angle control servo cylinder 30 drives the angle control plate 31 to clamp the upper and lower ends of the traction pin 4. Combined with the rotation of the rotating frame 6, the unhooking frame 8 and the traction pin 4 can be quickly adjusted to a horizontal state, which greatly improves the accuracy and efficiency of unhooking, and ensures that the electric locomotive and the passenger car can be reliably connected even under complex working conditions.

[0047] Furthermore, the hanging and picking positioning unit includes a positioning frame 35 and a positioning plate 37. Servo linear slides 32 are fixedly provided on opposite sides of the two connecting frames 17 located above and below, and positioning sliders 33 are slidably provided on one side of the two servo linear slides 32. A positioning rotating shaft 34 is rotatably provided between the upper and lower positioning sliders 33, and a servo motor for driving the positioning rotating shaft 34 to rotate is fixedly provided at the bottom of the upper positioning slider 33; a positioning frame 35 is fixedly provided on the surface of the positioning rotating shaft 34, and two hanging and picking positioning servo electric cylinders 36 are fixedly provided inside the positioning frame 35, and a positioning plate 37 is fixedly provided on the top of the driving shaft of the two hanging and picking positioning servo electric cylinders 36, and the surface of the positioning plate 37 is covered with a rubber pad.

[0048] It should be noted that when positioning the connection between the unhooking bracket 8 and the traction pin 4, the orientation of the unhooking bracket 8 is adjusted to be horizontal with the traction pin 4 through the upper and lower angle control plates 31. At this time, the positioning rotation shafts 34 on both sides are used to control the two positioning brackets 35 to be angularly deflected toward one side of the traction pin 4, and the driving end of the unhooking positioning servo electric cylinder 36 is controlled to control the positioning plate 37 to approach the two sides of the surface of the traction pin 4. Under the clamping positioning of the two positioning plates 37 on both sides of the surface of the traction pin 4, the traction pin 4 is located in the middle between the two unhooking positioning servo electric cylinders 36, and aligned with the position of the unhooking bracket 8. At this time, the electric locomotive traction part 1 and the passenger car connection part 2 are controlled to continue to approach, so that the traction pin 4 and the unhooking bracket 8 can be connected quickly and accurately, which greatly improves the connection efficiency between the traction pin 4 and the unhooking bracket 8.

[0049] In a specific embodiment, the design of the unhooking and hanging positioning unit of the present invention significantly improves the accuracy and efficiency of the connection between the electric locomotive and the passenger car through the collaborative operation of multiple components. The linear sliding structure composed of the servo linear slide 32 and the positioning slider 33, in conjunction with the positioning rotating shaft 34 and its driving servo motor, can flexibly adjust the position and angle of the positioning frame 35 to make it accurately close to the traction pin 4; the unhooking and hanging positioning servo cylinder 36 drives the positioning plate 37 to approach the two sides of the traction pin 4 surface. The rubber pads on the surface of the positioning plate 37 can not only increase the friction to prevent the traction pin 4 from sliding, but also avoid rigid contact and damage to the components; after the angle control unit adjusts the unhooking and hanging frame 8 and the traction pin 4 to a horizontal state, the unhooking and hanging positioning unit clamps and positions the traction pin 4 through the positioning plates 37 on both sides to ensure that the traction pin 4 is accurately in the corresponding center position of the unhooking and hanging frame 8, so that when the electric locomotive traction part 1 and the passenger car connection part 2 approach each other subsequently, the traction pin 4 can quickly and accurately complete the connection with the unhooking and hanging frame 8, greatly reducing the alignment time, improving the hooking efficiency, and ensuring the efficiency and reliability of the electric locomotive's automatic unhooking and hanging operation.

[0050] Example 3

[0051] Specifically, this embodiment discloses a control method for an automatic unhooking and hooking control system for an electric locomotive, including the following steps:

[0052] Preparation stage: the electric locomotive traction part 1 and the passenger car connection part 2 are close to each other, and the angle control unit and the hook-and-hook positioning unit on the rotating frame 6 on one side of the electric locomotive traction part 1 start to work.

[0053] Angle control: The connecting sliders 18 on the connecting frames 17 on the upper and lower sides of the rotating frame 6 slide in the connecting grooves, driving the retractable rotating assembly composed of the rotating pin shaft 19, the rotating connecting block 120, the connecting rod 121, the connecting rod 22 and the buffer spring 23 to move, so that the angle adjustment frame 26 produces displacement and angle changes; the angle control servo electric cylinder 30 in the angle adjustment frame 26 drives the angle control plate 31 to approach and clamp the upper and lower ends of the traction pin 4 respectively, and at the same time the rotating frame 6 rotates around the rotating axis 7, so that the hanging frame 8 and the traction pin 4 are in a horizontal state.

[0054] Positioning stage: the servo linear slides 32 on the connecting frames 17 on both sides drive the positioning slider 33 to slide, and the positioning rotating shaft 34 rotates under the drive of the servo motor, causing the positioning frame 35 to deflect toward the side of the traction pin 4; the picking and hanging positioning servo electric cylinder 36 in the positioning frame 35 drives the positioning plate 37 to approach and clamp the two sides of the surface of the traction pin 4, positioning the traction pin 4 in the middle between the two picking and hanging positioning servo electric cylinders 36, and aligning it with the position of the picking and hanging frame 8.

[0055] Hooking stage: control the electric locomotive traction part 1 and the passenger car connection part 2 to continue to approach, one side of the traction pin 4 is sent into the hooking inner cavity 9 inside the hooking frame 8, and one end of the traction pin 4 contacts one side of the buffer frame 10; the butterfly springs 11 at the top and bottom of the buffer frame 10 cooperate with the damper inside it to buffer the impact force during connection; the adjustment motor 14 drives the adjustment screw 13 to rotate, so that the two sliding guide blocks are relatively displaced in the movable groove 12, driving the hooking limit part 15 to approach the surface of the traction pin 4, and the connecting groove covers both sides of the surface of the traction pin 4. The microelectronic control unit inside the hooking limit part 15 controls the on and off and size of the current, so that the deformation limit frame 16 is deformed, and the surface of the traction pin 4 is completely covered. After cooling, the traction pin 4 is completely covered and hooked in the hooking inner cavity 9.

[0056] Unhooking stage: the microelectronic control unit controls the current to restore the deformed limit frame 16 to its original state, release the covering of the traction pin 4, adjust the motor 14 to reverse, separate the unhooking limit part 15 from the traction pin 4, and the electric locomotive traction part 1 and the passenger car connection part 2 move in opposite directions to achieve unhooking.

[0057] It should be noted that, in the preparation stage, the distance between the electric locomotive traction part 1 and the passenger car connection part 2 is detected by a laser ranging sensor or an infrared sensor. When the distance reaches the preset threshold value D, the angle control unit and the detachment and hanging positioning unit start to start; in the angle control stage, the angle of the rotating frame 6 is monitored in real time by the angle sensor. When it is detected that the angle deviation between the detachment and hanging frame 8 and the traction pin 4 exceeds β degrees, the angle control servo cylinder 30 adjusts the position of the angle control plate 31 according to the deviation value through the PID control algorithm until the angle deviation is less than the set value; in the positioning and hanging stage, a pressure sensor is also introduced to feedback the clamping force of the positioning plate 37, the force condition of the buffer frame 10, etc., to realize closed-loop control and ensure the precise execution of each action.
