Description

Technical Field

[0001] This utility model relates to the field of rail transit vehicle maintenance technology, specifically to a device for adjusting the extension of the electrical hook of a coupler. Background Technology

[0002] In modern rail transit systems, each train is equipped with a connection system. This system mainly consists of two parts: the coupler and the electric coupler. The coupler, as the core component of the physical connection, bears the heavy responsibility of connecting two train cars and transmitting traction and braking forces. The electric coupler, on the other hand, focuses on the connection of electrical signals, ensuring the accurate transmission of various control and communication signals during train operation, thus enabling intelligent control and coordinated operation of the train system. Typically, the coupler and electric coupler are designed to be arranged side-by-side. This layout facilitates installation and maintenance while maximizing space utilization.

[0003] The coupler's surface is designed as a base plate structure with unique mechanical features on both sides. One side features an outwardly protruding mechanical hook head cone surface equipped with a rocker arm structure. The other side of the base plate is the inner cavity surface of the mechanical hook head, which houses a latching structure. The latching structure and the rocker arm structure work together to form a reliable locking mechanism. Furthermore, an air passage is cleverly integrated into the base plate surface, providing a crucial interface for subsequent air-driven operation.

[0004] When two trains need to be connected, the connection system comes into play. The two base plates gradually approach each other, and the mechanical hook protrusion of one base plate precisely inserts into the inner cavity of the mechanical hook of the other base plate. During this process, the rocker arm structure cleverly engages with the opposing snap-fit ​​structure, thus achieving a secure lock between the two couplers and completing the physical connection. At the same time, the air ports of the two base plates also align, forming a complete and sealed air passage. At this point, the air pump is activated, and compressed air transmits power through the air passage, driving specific drive components to move, which in turn pushes the electric hooks forward, tightly connecting the two electric hooks and achieving stable transmission of electrical signals.

[0005] To ensure the stability of the electric coupler connection, the surface of the electric coupler needs to protrude a certain amount from the surface of the base plate. This design requirement is to ensure that the electric coupler maintains good contact during train operation, even under complex conditions such as vibration and impact, avoiding problems such as signal interruption or poor contact. However, detecting this critical protrusion amount faces many challenges. According to the current specifications for electric coupler measurement operations, another train with the same model of coupler must be present for coordination. This means that during measurement operations, it is necessary to coordinate two trains to be parked at designated locations and to perform precise docking operations simultaneously.

[0006] However, in actual operational scenarios, when train scheduling is at its peak, each train has its own predetermined operating tasks and schedules, making it difficult to allocate extra time and resources to coordinate electric coupler measurement operations. In such situations, it's challenging to coordinate a suitable train in a timely manner, causing the electric coupler extension measurement work to be delayed. This not only affects the overall progress of train maintenance, preventing trains from being put into operation promptly, but also incurs significant manpower and time costs. Over time, this will inevitably reduce the efficiency of train maintenance and have an adverse impact on the safe and efficient operation of rail transit. Utility Model Content

[0007] In order to overcome the problems existing in the prior art, the purpose of this utility model is to provide a device for adjusting the extension amount of the electric hook of a car coupler.

[0008] The technical solution adopted by this utility model to solve its technical problem is: a device for adjusting the extension amount of the electric hook of a car coupler, comprising: a base, a propulsion component, a docking component, and a fixing component;

[0009] The base is provided with a docking hole, which cooperates with the protruding conical surface of the mechanical hook. The fixing component is installed on one side of the docking hole. The fixing component is provided with a first fixing part and a second fixing part on both sides. The first fixing part cooperates with the protruding conical surface of the mechanical hook, and the second fixing part cooperates with the inner cavity surface of the mechanical hook.

[0010] The docking assembly of the base corresponds to the air inlet of the electric hook; the propulsion assembly is used to drive the docking assembly to move in a direction close to or away from the air inlet of the electric hook.

[0011] Main working principle: This device for adjusting the extension of the electric coupler includes a base, a propulsion assembly, a docking assembly, and a fixing assembly. The docking hole on the base mates with the protruding conical surface of the mechanical hook head. During installation and adjustment, the docking hole of the base is precisely fitted onto the protruding conical surface of the mechanical hook head, thus achieving initial positioning of the device on the mechanical hook head and ensuring accurate installation, laying the foundation for subsequent adjustment work. The fixing assembly is installed on one side of the docking hole, with a first fixing part and a second fixing part on each side. The first fixing part mates with the protruding conical surface of the mechanical hook head, and the second fixing part mates with the inner cavity surface of the mechanical hook head. After the base is initially positioned, the fixing assembly is operated to make the first fixing part tightly fit against the protruding conical surface of the mechanical hook head, and the second fixing part closely contact the inner cavity surface of the mechanical hook head. Utilizing the friction and clamping force between them, the entire adjustment device is firmly fixed to the mechanical hook head, preventing shaking or displacement during subsequent propulsion and adjustment, ensuring the stability and accuracy of the adjustment.

[0012] The propulsion assembly is mounted on the base, with its propulsion end facing the base. The bases are perpendicularly connected to each other, providing a stable mounting foundation and correct propulsion direction for the propulsion assembly. When adjusting the extension of the electric hook, the propulsion assembly is activated. Power is generated internally through pneumatic, hydraulic, or electric means, propelling its propulsion end towards the base. This propulsion method provides stable and precisely controllable thrust, meeting the precise adjustment requirements for the electric hook extension under various debugging needs.

[0013] The propulsion end of the propulsion assembly is connected to the docking assembly, and the docking assembly is connected to the air inlet of the electric hook. When the propulsion end of the propulsion assembly moves, it drives the docking assembly to move as well. As the component between the propulsion assembly and the electric hook, the docking assembly accurately transmits the thrust generated by the propulsion assembly to the electric hook. After the docking assembly is connected to the air inlet of the electric hook, it ensures that the thrust acts directly on the key parts of the electric hook, enabling the electric hook to extend or retract in the expected direction and amplitude. During propulsion, the docking assembly ensures efficient and accurate power transmission, avoiding power loss and transmission deviation, thereby achieving precise control over the extension amount of the electric hook.

[0014] Under the combined action of the propulsion and docking components, the electric hook begins to extend. Operators can precisely adjust the extension length of the electric hook by controlling the propulsion amount of the propulsion component, thereby achieving the adjustment of the electric hook's extension amount. During the adjustment process, the extension amount of the electric hook can be measured in real time using professional measuring tools (such as vernier calipers). When the extension amount reaches the design requirement of 1.5mm ± 0.5mm, the operation of the propulsion component is stopped; at this point, the extension amount of the electric hook meets the standard adjustment result. After adjustment, if it is necessary to retract the electric hook, the propulsion component can be controlled to move in the opposite direction, driving the docking component to retract the electric hook to its initial position.

[0015] In summary, this device for adjusting the extension of the electric coupler achieves precise and efficient adjustment of the electric coupler extension through the close cooperation and coordinated work of its components. It solves the problems of relying on additional trains and time-consuming multi-disciplinary collaboration in existing technologies, thereby improving the efficiency and quality of train maintenance.

The docking block faces the air inlet of the electric hook, and the size and shape of the docking block and the air inlet of the electric hook are opposite. One end of the connecting rod is connected to the docking block, and the other end of the connecting rod is connected to the propulsion assembly.

[0017] Preferably, the docking assembly further includes a first guide block and a guide rod. The first guide block is connected to the docking block and has a guide hole. The guide rod is connected to the base and its movement trajectory is parallel to that of the docking block. The guide hole and the guide rod cooperate with each other.

[0018] Preferably, the propulsion assembly includes a base and a push-pull rod, the base being mounted on the base, the push-pull rod sliding on the base, and the push-pull rod being connected to the docking assembly.

[0019] Preferably, the fixing component includes a fixing block connected to the base, and the first fixing part and the second fixing part are respectively connected to both sides of the fixing block.

[0020] Preferably, the fixing component further includes a driving unit and a support, the support being connected to the base, the driving unit being connected to the support, and the driving end of the driving unit facing the base, and the driving end of the driving unit being connected to the fixing block.

[0021] Preferably, the support is provided with a guide groove, which is parallel to the driving end of the driving unit. A second guide block is provided on one side of the fixing block, which can slide along the guide groove when inserted into it.

[0022] Preferably, the drive unit includes a lead screw, which is threadedly connected to the fixed block, and the end of the lead screw is connected to an external motor or throttle.

[0023] Preferably, the end of the first fixing part is provided with a buckle, which cooperates with the protruding conical surface of the mechanical hook head; the end of the second fixing part includes a swing rod, one end of which is connected to the rotating shaft of the fixing block, and the other end of which is provided with a protrusion, which cooperates with the inner cavity surface of the mechanical hook head.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] This invention utilizes a base, a propulsion assembly, a docking assembly, and a fixing assembly in a coupler electrical hook extension adjustment device. Through the coordinated action of these components, operators only need basic adjustment skills and operating methods to independently complete the adjustment of the electrical hook extension. This significantly reduces the need for multi-disciplinary collaboration, simplifies the workflow, significantly shortens the average working time, reduces labor and time costs, and improves the efficiency of train maintenance. Compared to existing technologies, it overcomes the shortcomings of requiring collaboration among multiple disciplines such as train drivers, overhead contact line specialists, depot maintenance personnel, and rolling stock specialists, resulting in complex and time-consuming processes.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0035] Example 1

[0036] This embodiment discloses a device for adjusting the extension amount of the electrical hook of a train coupler, such as... Figures 1-4 As shown, the device includes a base 1, a propulsion assembly 3, a docking assembly 4, and a fixing assembly 5. The docking hole 10 on the base 1 mates with the conical surface of the mechanical hook head. During installation and debugging, the docking hole 10 of the base 1 is precisely fitted onto the conical surface of the mechanical hook head to achieve initial positioning of the device on the mechanical hook head, ensuring accurate installation and laying the foundation for subsequent debugging. The fixing assembly 5 is installed on the base 1 and located on one side of the docking hole 10, with a first fixing part 50 and a second fixing part 51 on its two sides. The first fixing part 50 mates with the conical surface of the mechanical hook head, and the second fixing part 51 mates with the inner cavity surface of the mechanical hook head. After the base 1 is initially positioned, the fixing assembly 5 is operated to ensure that the first fixing part 50 is tightly fitted against the conical surface of the mechanical hook head, and the second fixing part 51 is in close contact with the inner cavity surface of the mechanical hook head. Utilizing the friction and clamping force between the two, the entire debugging device is firmly fixed to the mechanical hook head, preventing shaking or displacement during subsequent propulsion and debugging, and ensuring the stability and accuracy of the debugging process.

[0037] The propulsion assembly 3 is mounted on the base 1, providing a stable mounting foundation and correct propulsion direction. When the extension of the electric hook needs to be adjusted, the propulsion assembly 3 is activated. The propulsion assembly 3 generates power internally through pneumatic, hydraulic, or electric means, propelling its propulsion end towards the base 1. This propulsion method provides stable and precisely controllable thrust, meeting the precise adjustment of the electric hook extension under different adjustment requirements.

[0038] The propulsion end of the propulsion assembly 3 is connected to the docking assembly 4, and the docking assembly 4 is connected to the air inlet of the electric hook. When the propulsion end of the propulsion assembly 3 moves, it drives the docking assembly 4 to move as well. As a component between the propulsion assembly 3 and the electric hook, the docking assembly 4 accurately transmits the thrust generated by the propulsion assembly 3 to the electric hook. After the docking assembly 4 is connected to the air inlet of the electric hook, it ensures that the thrust acts directly on the key parts of the electric hook, enabling the electric hook to extend or retract in the expected direction and range. During the propulsion process, the docking assembly 4 ensures the high efficiency and accuracy of power transmission, avoids power loss and transmission deviation, thereby achieving precise control of the extension amount of the electric hook.

[0039] Under the combined action of the propulsion component 3 and the docking component 4, the electric hook begins to extend. Operators can precisely adjust the extension length of the electric hook by controlling the propulsion amount of the propulsion component 3, thereby achieving the debugging of the electric hook's extension amount. During the debugging process, the extension amount of the electric hook can be measured in real time using professional measuring tools (such as vernier calipers). When the extension amount reaches the design requirement of 1.5mm ± 0.5mm, the operation of the propulsion component 3 is stopped; at this point, the extension amount of the electric hook is the standard debugging result. After debugging, if it is necessary to retract the electric hook, the propulsion component 3 can be controlled to move in the opposite direction, driving the docking component 4 to retract the electric hook to its initial position.

[0040] In summary, the coupler extension adjustment device of this embodiment achieves precise and efficient adjustment of the electric coupler extension through the close cooperation and coordinated work of various components. It solves the problems of relying on additional trains and time-consuming multi-disciplinary collaboration in the prior art, and improves the efficiency and quality of train maintenance.

[0041] In some optional embodiments, the docking block 40 of the docking assembly 4 faces the air inlet of the electric hook and is sized and shaped opposite to it to ensure accurate docking with the air inlet. One end of the connecting rod 41 is connected to the docking block 40, and the other end is connected to the propulsion assembly 3, which transmits the power of the propulsion assembly 3 to the docking block 40, and then the docking block 40 acts on the air inlet of the electric hook to realize the power transmission and drive the electric hook to move.

[0042] In some optional embodiments, the first guide block 42 is connected to the docking block 40 and is provided with a guide hole 420. The guide rod 43 is connected to the base 1 and is parallel to the movement trajectory of the docking block 40. The guide hole 420 and the guide rod 43 cooperate. During the movement of the docking block 40, the guide rod 43 slides in the guide hole 420, which plays a guiding role, ensuring that the docking block 40 moves accurately along a straight line, avoiding deviation, and improving the accuracy of the electric hook extension adjustment.

[0043] In some alternative embodiments, the base 30 of the propulsion assembly 3 is mounted on the base 1, providing stable support for the push-pull rod 31. The push-pull rod 31 slides on the base 30 and is connected to the docking assembly 4. By pushing or pulling the push-pull rod 31, linear motion is transmitted to the docking assembly 4, thereby causing the electric hook to extend or retract, thus adjusting the extension amount of the electric hook.

[0044] In some optional embodiments, the fixing block 52 of the fixing component 5 is connected to the base 1, and the first fixing part 50 and the second fixing part 51 are respectively connected to both sides of the fixing block 52. The first fixing part 50 mates with the conical surface of the mechanical hook head, and the second fixing part 51 mates with the inner cavity surface of the mechanical hook head. The fixing block 52 connects the two into a whole, and together they fix the device to the mechanical hook head.

[0045] In some alternative embodiments, the support 55 is connected to the base 1, providing a mounting base for the drive unit 54. The drive unit 54 is connected to the support 55 with its drive end facing the base 1, and the drive end is connected to the fixing block 52. When the drive unit 54 is activated, its drive end pushes or pulls the fixing block 52, causing the fixing block 52 to move the first fixing part 50 and the second fixing part 51, thereby realizing the fixing or loosening operation with the mechanical hook.

[0046] In some optional embodiments, the support 55 is provided with a guide groove 56 and is parallel to the driving end of the drive unit 54. A second guide block 53 on one side of the fixing block 52 is inserted into the guide groove 56. When the drive unit 54 drives the fixing block 52 to move, the second guide block 53 slides along the guide groove 56, playing a guiding and limiting role, ensuring that the fixing block 52 moves accurately along a straight line, so that the first fixing part 50 and the second fixing part 51 can accurately cooperate with the mechanical hook, improving the stability and accuracy of the fixing.

[0047] In some optional embodiments, the lead screw 540 of the drive unit 54 is threadedly connected to the fixing block 52, and the end of the lead screw 540 is connected to an external motor or throttle. When the motor rotates or the throttle is turned, the lead screw 540 rotates, and due to the thread action, the fixing block 52 moves along the axial direction of the lead screw 540, thereby driving the fixing block 52 to move the first fixing part 50 and the second fixing part 51, completing the fixing or loosening operation with the mechanical hook.

[0048] In some optional embodiments, the latch 500 at the end of the first fixing part 50 engages with the conical surface of the mechanical hook head, enhancing the fixing effect through the clamping action of the latch 500. One end of the swing rod 510 at the end of the second fixing part 51 is connected to the rotating shaft of the fixing block 52, and the other end's protrusion 511 engages with the inner cavity surface of the mechanical hook head. During fixing, the swing rod 510 rotates around the rotating shaft, causing the protrusion 511 to make close contact with the inner cavity surface of the mechanical hook head, fixing the device from different directions and improving the stability of the fixation.

[0049] In some optional embodiments, the positioning component 6 is connected to the fixed component 5, the moving part 61 passes through the fixed component 5 and is movably connected, and its end is connected to the positioning part 60, with the end of the positioning part 60 facing the docking component 4. During the debugging process, the positioning component 6 is moved to move the positioning part 60 to a suitable position to locate the movement position of the docking component 4, which helps to determine the debugging endpoint of the electric hook extension and improves the debugging accuracy.

[0050] In some alternative embodiments, the end of the positioning part 60 is tapered, and it comes into close contact with the first guide block 42 during positioning. The tapered design allows for a tighter contact between the positioning part 60 and the first guide block 42, reducing positioning errors. When the first guide block 42 moves to contact the tapered end of the positioning part 60, it is blocked by the positioning part 60, thereby determining the movement position of the docking assembly 4 and accurately determining the extension amount of the electric hook.

[0051] In some optional embodiments, one end of the swing arm 510 is connected to the fixed block 52 via a rotating shaft. The rotating shaft has a connecting hole through which the moving part 61 of the positioning component 6 passes and engages with the fixed component 5. This design makes the positioning component 6 and the swing arm 510 structurally interconnected and compact, saving space. During operation, moving the moving part 61 of the positioning component 6 achieves the positioning function without interfering with other components, ensuring the compactness and coordination of the overall device structure.

[0052] Example 2

[0053] A method for adjusting the extension of the electrical hook in a train coupler, comprising the following steps:

[0054] S1: The docking hole 10 on the base 1 cooperates with the conical surface of the mechanical hook head. When the conical surface of the mechanical hook head enters the docking hole 10, the slope of the conical surface can guide the mechanical hook head to automatically adjust its position so that its axis coincides with the axis of the docking hole 10 as much as possible, thereby achieving preliminary positioning and fixing, and providing a basis for subsequent precise fixing.

[0055] The latch 500 at the end of the first fixing part 50 engages with the conical surface of the mechanical hook head to lock in place. The latch 500 typically has a certain degree of elasticity; when in contact with the conical surface of the mechanical hook head, its elasticity allows it to deform, thus smoothly locking into the corresponding position on the conical surface. After locking, the elastic restoring force of the latch 500 generates an inward clamping force, firmly fixing the mechanical hook head to the base 1 and preventing horizontal movement. One end of the rocker arm 510 at the end of the second fixing part 51 is connected to the rotating shaft of the fixing block 52, and the other end is provided with a protrusion 511. When the rocker arm 510 is rotated, it moves in a circular motion around the rotating shaft, causing the protrusion 511 to gradually approach the inner cavity surface of the mechanical hook head. As the rocker arm 510 continues to rotate, the protrusion 511 comes into contact with the inner surface of the mechanical hook. At this time, sufficient friction is generated between the protrusion 511 and the inner surface of the mechanical hook, thereby fixing the mechanical hook in the vertical direction and preventing it from moving up and down or wobbling. Through the combined action of the first fixing part 50 and the second fixing part 51, the mechanical hook is firmly fixed on the base 1, providing a stable foundation for subsequent debugging work.

[0056] S2. The drive unit 54 is connected to the fixed block 52. When the drive unit 54 is activated according to debugging requirements, it generates a driving force. The drive unit 54 includes a lead screw 540, which is threadedly connected to the fixed block 52. When the lead screw 540 rotates under the drive of a motor or throttle, according to the principle of threaded transmission, the rotational motion of the lead screw 540 is converted into the linear motion of the fixed block 52. The rotation direction of the lead screw 540 determines the movement direction of the fixed block 52. By controlling the number of rotations and the rotation speed of the lead screw 540, the movement distance and speed of the fixed block 52 can be precisely controlled. The fixed block 52 is connected to the first fixed part 50 and the second fixed part 51 on both sides. When the fixed block 52 moves along the guide groove 56 under the drive of the drive unit 54, it will drive the first fixed part 50 and the second fixed part 51 to move together. Since the first fixed part 50 and the second fixed part 51 are fixedly connected to the mechanical hook, the mechanical hook will also move accordingly. The guide groove 56 provides precise guidance for the movement of the fixed block 52, ensuring that the fixed block 52 can only move in the predetermined direction, thereby guaranteeing the accuracy and stability of the mechanical hook position adjustment. In this way, the position of the mechanical hook can be fine-tuned according to actual debugging needs to achieve the ideal debugging position.

[0057] S3. The propulsion assembly 3 is mounted on the base 1, with its propulsion end facing the base 1 and connected to the docking assembly 4. When the propulsion assembly 3 is activated, the push-pull rod 31 inside the propulsion assembly 3 generates a thrust, pushing the push-pull rod 31 to slide on the base 30. The push-pull rod 31 transmits the thrust to the docking assembly 4 through the connecting rod 41, causing the docking assembly 4 to move towards the air inlet of the electric hook. The docking block 40 of the docking assembly 4 faces the air inlet of the electric hook, and the docking block 40 is sized and shaped relative to the air inlet of the electric hook. As the docking assembly 4 moves forward under the push of the propulsion assembly 3, the docking block 40 gradually docks with the air inlet of the electric hook. During the docking process, the docking block 40 applies a forward thrust to the electric hook. Due to the connection structure and motion relationship between the electric hook and the coupler, the electric hook will protrude forward under the action of this thrust.

[0058] S4. When the electric hook protrudes forward, it will extend beyond the coupler plane by a certain amount. This extension can be measured using appropriate measuring tools (such as vernier calipers, dial indicators, etc.). Place the measuring end of the tool on the protruding part of the electric hook and the corresponding position on the coupler plane, and read the value on the tool to obtain the extension of the electric hook. Based on the measurement results, it can be determined whether the extension of the electric hook meets the design requirements and debugging standards. If the extension does not meet the requirements, it can be readjusted by adjusting the pushing amount of the pushing component 3, fine-tuning the position of the mechanical hook head, etc., until the extension of the electric hook reaches the qualified range, thus completing the debugging of the coupler electric hook extension.

[0059] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
