Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rail transit vehicle maintenance, in particular to a device and method for adjusting the extension amount of an electrical coupler. BACKGROUND

[0002] In modern rail transit systems, each train is equipped with a connection system. This system is mainly composed of two parts: the coupler and the electrical coupler. The coupler, as the core component of physical connection of the train, bears the responsibility of connecting two trains and transmitting traction force and braking force. The electrical coupler, on the other hand, focuses on the connection of electrical signals, ensuring that various control signals, communication signals, etc. can be accurately transmitted during train operation, achieving intelligent control and collaborative operation of the train system. Typically, the coupler and the electrical coupler are designed in a side-by-side layout, which is convenient for installation and maintenance, and also optimizes space utilization to the maximum extent.

[0003] The surface of the coupler is designed as a base plate structure, with unique mechanical structures on both sides. One side is a mechanical hook head protruding outward, equipped with a swing lever structure. The other side of the base plate is a mechanical hook head inner cavity surface, with a buckle structure inside. The buckle structure and the swing lever structure cooperate to form a reliable locking mechanism. In addition, an air port is cleverly arranged on the surface of the base plate, which provides a key interface for subsequent air path driving.

[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 head protruding surface of one base plate precisely inserts into the mechanical hook head inner cavity surface of the other base plate. In this process, the swing lever structure cleverly engages with the opposite buckle structure, thereby achieving firm locking of the two couplers and completing the physical connection. At the same time, the air ports of the two base plates also dock with each other, forming a complete and sealed air path. At this time, the air pump is started, and compressed air will pass through the air path to drive the specific driving part to move, thereby pushing the electrical coupler to extend forward, making the two electrical couplers tightly connected and realizing stable transmission of electrical signals.

[0005] In order to ensure the stability of the electrical coupler connection, the surface of the electrical coupler needs to maintain a certain amount of extension compared to the surface of the base plate. This design requirement is to ensure that during train operation, even in complex conditions such as vibration and impact, the electrical coupler can still maintain good contact and avoid problems such as signal interruption or poor contact. However, detecting this critical extension amount faces many challenges. According to the current specification requirements for electrical coupler measurement operations, another train with the same type of coupler must be used as a match. This means that when performing measurement operations, two trains need to be coordinated and parked at designated locations, and precise docking operations need to be performed.

[0006] But in the actual operation scene, when the train scheduling is in the busy stage, each train has its scheduled operation task and time arrangement, it is difficult to spare additional time and resources to cooperate with the electric hook measurement operation. In this case, it is difficult to coordinate the qualified train in time, which causes the electric hook extension measurement work to be unable to carry out on schedule according to the plan. This not only affects the overall progress of train maintenance, but also causes the train to be unable to put into operation in time, and also consumes a large amount of manpower and time cost. In the long run, it will inevitably reduce the efficiency of train maintenance, and will have an adverse effect on the safe and efficient operation of rail transit. SUMMARY

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

[0008] The technical scheme adopted by the present application to solve its technical problems is: a device for adjusting the extension of the electric hook of the car coupler, comprising: a base, a pushing assembly, a docking assembly and a fixing assembly.

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

[0010] The docking assembly of the base corresponds to the air port of the electric hook; the pushing assembly is used to drive the docking assembly to move in the direction of approaching or moving away from the air port of the electric hook.

[0011] The main working principle: the device for adjusting the extension of the electric hook of the car coupler comprises a base, a pushing assembly, a docking assembly and a fixing assembly. The docking hole provided on the base cooperates with the conical surface of the mechanical hook head. When installing and debugging the device, the docking hole of the base is accurately sleeved on the conical surface of the mechanical hook head, so as to realize the preliminary positioning of the device on the mechanical hook head, ensure the accuracy of the device installation position, and lay a foundation for the subsequent debugging work. The fixing assembly is installed on one side of the docking hole, and the first fixing part and the second fixing part are respectively arranged on both sides. The first fixing part cooperates with the conical surface of the mechanical hook head, and the second fixing part cooperates with the inner cavity surface of the mechanical hook head. After the preliminary positioning of the base, the first fixing part is tightly attached to the conical surface of the mechanical hook head, and the second fixing part is tightly contacted with the inner cavity surface of the mechanical hook head, and the friction and clamping force between the two are used to firmly fix the entire debugging device on the mechanical hook head, prevent the device from shaking or shifting during the subsequent pushing and debugging process, and ensure the stability and accuracy of the debugging.

[0012] The propulsion assembly is installed on the base, and the propulsion end faces the base. The base is connected to the base perpendicularly, providing a stable installation foundation and correct propulsion direction for the propulsion assembly. When electrical hook extension adjustment is needed, the propulsion assembly is started, and the propulsion assembly generates power through air pressure, hydraulic pressure, or electricity, etc. inside, pushing the propulsion end to move in the direction towards the base.

After the docking assembly is connected to the air port of the electrical hook, it can ensure that the thrust acts directly on the key parts of the electrical hook, so that the electrical hook can extend or retract according to the expected direction and amplitude. During the propulsion process, the docking assembly ensures the efficiency and accuracy of power transmission, avoiding power loss and transmission deviation, thereby achieving precise control of the electrical hook extension.

[0014] Under the joint action of the propulsion assembly and the docking assembly, the electrical hook begins to extend. The operator can accurately adjust the extension length of the electrical hook by controlling the propulsion amount of the propulsion assembly according to actual needs, thereby realizing the adjustment of the electrical hook extension. During the adjustment process, professional measuring tools (such as vernier calipers, etc.) can be used to measure the extension of the electrical hook in real time. When the extension reaches the design requirement of 1.5mm±0.5mm, stop the work of the propulsion assembly, and the extension of the electrical hook at this time is the standard adjustment result. After the adjustment is completed, if the electrical hook needs to be retracted, the propulsion assembly can be controlled to move in the opposite direction, driving the docking assembly to retract the electrical hook to the initial position.

[0015] In summary, the electrical hook extension adjustment device for the car coupler realizes precise and efficient adjustment of the electrical hook extension through the close cooperation and coordinated work of each component, solves the problems of relying on additional trains and multiple professional collaboration in the prior art, and improves the efficiency and quality of train maintenance.

The butt joint hole 10 provided on the base 1 cooperates with the mechanical hook head protruding conical surface.

The fixing assembly 5 is installed on the base 1 and located on one side of the butt joint hole 10, and the first fixing part 50 and the second fixing part 51 are respectively arranged on the two sides thereof. The first fixing part 50 cooperates with the mechanical hook head protruding conical surface, and the second fixing part 51 cooperates with the mechanical hook head inner cavity surface. After the base 1 is preliminarily positioned, the first fixing part 50 is tightly attached to the mechanical hook head protruding conical surface, and the second fixing part 51 is tightly contacted with the mechanical hook head inner cavity surface, so as to firmly fix the entire adjusting device on the mechanical hook head by means of the friction force and clamping force between the two, prevent the device from shaking or shifting during the subsequent advancing adjustment process, and ensure the stability and accuracy of the adjustment. Figures 1-4 ​

[0041] The propulsion assembly 3 is installed on the base 1, providing a stable installation foundation and correct propulsion direction for the propulsion assembly 3. When electrical hook extension adjustment is required, the propulsion assembly 3 is started, and the power inside the propulsion assembly 3 is generated by means of air pressure, hydraulic pressure, or electricity, etc., to push the propulsion end in the direction towards the base 1. This propulsion method can provide stable and accurately controllable thrust to meet the precise adjustment of the electrical hook extension under different adjustment requirements.

[0042] 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 port of the electrical hook. When the propulsion end of the propulsion assembly 3 moves, it will drive the docking assembly 4 to move together. The docking assembly 4, as a component between the propulsion assembly 3 and the electrical hook, accurately transmits the thrust generated by the propulsion assembly 3 to the electrical hook. After the docking assembly 4 is connected to the air port of the electrical hook, it can ensure that the thrust directly acts on the key part of the electrical hook, so that the electrical hook can extend or retract according to the expected direction and amplitude. During the propulsion process, the docking assembly 4 ensures the efficiency and accuracy of power transmission, avoiding power loss and transmission deviation, thereby achieving precise control of the electrical hook extension.

[0043] Under the joint action of the propulsion assembly 3 and the docking assembly 4, the electrical hook begins to extend. The operator can accurately adjust the extension length of the electrical hook by controlling the propulsion amount of the propulsion assembly 3 according to actual requirements, thereby achieving the adjustment of the electrical hook extension. During the adjustment process, professional measuring tools (such as vernier calipers, etc.) can be used to measure the extension of the electrical hook in real time. When the extension reaches the design requirement of 1.5mm±0.5mm, stop the work of the propulsion assembly 3, and the extension of the electrical hook at this time is the standard adjustment result. After the adjustment is completed, if the electrical hook needs to be retracted, the propulsion assembly 3 can be controlled to move in the opposite direction to drive the docking assembly 4 to retract the electrical hook to the initial position.

[0044] In summary, the electrical hook extension adjustment device for the car coupler of the present embodiment realizes precise and efficient adjustment of the electrical hook extension through the close cooperation and joint work of various components, solves the problems of relying on additional trains and multiple professional cooperation in the prior art, and improves the efficiency and quality of train maintenance.

[0045] In some optional embodiments, the docking block 40 of the docking assembly 4 is relatively sized and shaped towards the air port of the electrical hook to ensure accurate docking with the air port. The connecting rod 41 has one end connected to the docking block 40 and the other end 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 port of the electrical hook to realize power transmission to drive the electrical hook to move.

[0046] In some optional embodiments, the first guide block 42 is connected with the docking block 40 and provided with a guide hole 420, the guide rod 43 is connected with the base 1 and parallel to the movement track of the docking block 40, and the guide hole 420 cooperates with the guide rod 43. During the movement of the docking block 40, the guide rod 43 slides in the guide hole 420, plays a guiding role, ensures the accurate movement of the docking block 40 along a straight line, avoids deviation, and improves the accuracy of the adjustment of the extension amount of the electrical hook.

[0047] In some optional embodiments, the base 30 of the pushing assembly 3 is installed on the base 1 to provide stable support for the push-pull rod 31. The push-pull rod 31 slides on the base 30 and is connected with the docking assembly 4. By pushing or pulling the push-pull rod 31, linear movement is transmitted to the docking assembly 4, thereby driving the electrical hook to extend or retract, and achieving the adjustment of the extension amount of the electrical hook.

[0048] In some optional embodiments, the fixing block 52 of the fixing assembly 5 is connected with the base 1, and the first fixing part 50 and the second fixing part 51 are respectively connected on both sides of the fixing block 52. The first fixing part 50 cooperates with the mechanical hook head protruding conical surface, and the second fixing part 51 cooperates with the mechanical hook head inner cavity surface, and the two are connected into a whole by the fixing block 52, and the fixing block 52 cooperates with the two to fix the device on the mechanical hook head.

[0049] In some optional embodiments, the support 55 is connected with the base 1 to provide a mounting basis for the driving unit 54. The driving unit 54 is connected with the support 55 and the driving end faces the base 1. The driving end is connected with the fixing block 52. When the driving unit 54 is started, the driving end pushes or pulls the fixing block 52, so that the fixing block 52 drives the first fixing part 50 and the second fixing part 51 to move, thereby achieving the fixing or loosening operation with the mechanical hook head.

[0050] In some optional embodiments, the support 55 is provided with a guide groove 56 parallel to the driving end of the driving unit 54, and the second guide block 53 on one side of the fixing block 52 is inserted into the guide groove 56. When the driving unit 54 drives the fixing block 52 to move, the second guide block 53 slides along the guide groove 56, plays a guiding and limiting role, ensures the accurate movement of the fixing block 52 along a straight line, and enables the first fixing part 50 and the second fixing part 51 to accurately cooperate with the mechanical hook head, thereby improving the stability and accuracy of the fixing.

[0051] In some optional embodiments, the lead screw 540 of the driving unit 54 is threadedly connected with the fixing block 52, and the end of the lead screw 540 is connected with an external motor or a rotating handle. When the motor rotates or the rotating handle rotates, the lead screw 540 rotates, and due to the thread action, the fixing block 52 moves axially along the lead screw 540, thereby driving the first fixing part 50 and the second fixing part 51 to move, and completing the fixing or loosening operation with the mechanical hook head.

[0052] In some alternative embodiments, the buckle 500 at the end of the first fixing part 50 cooperates with the conical surface of the mechanical hook head, and the fixing effect is enhanced by the clamping action of the buckle 500. The swing lever 510 at the end of the second fixing part 51 is connected to the rotating shaft of the fixing block 52 at one end, and the protrusion 511 at the other end cooperates with the inner cavity surface of the mechanical hook head. During fixing, the swing lever 510 rotates around the rotating shaft, so that the protrusion 511 is in close contact with the inner cavity surface of the mechanical hook head, thereby fixing the device from different directions and improving the firmness of the fixing.

[0053] In some alternative embodiments, the positioning assembly 6 is connected to the fixing assembly 5, the moving part 61 passes through the fixing assembly 5 and is movably connected, the end is connected to the positioning part 60, and the end of the positioning part 60 faces the docking assembly 4. During debugging, the positioning assembly 6 is moved, the positioning part 60 is moved to the appropriate position, the movement position of the docking assembly 4 is positioned, the debugging endpoint of the electrical hook extension amount is determined, and the debugging accuracy is improved.

[0054] In some alternative embodiments, the end of the positioning part 60 is conical and in contact with the first guide block 42 during positioning. The conical design enables the positioning part 60 to be in closer contact with the first guide block 42, thereby reducing positioning errors. When the first guide block 42 moves to contact the conical 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 electrical hook extension amount.

[0055] In some alternative embodiments, one end of the swing lever 510 is connected to the fixing block 52 through a rotating shaft, a connecting hole is provided in the rotating shaft, and the moving part 61 of the positioning assembly 6 passes through the connecting hole to cooperate with the fixing assembly 5. This design makes the positioning assembly 6 and the swing lever 510 structurally related and compact, saving space. During operation, moving the moving part 61 of the positioning assembly 6 can achieve the positioning function without interfering with other components, ensuring the compactness and coordination of the overall structure of the device.

[0056] Embodiment 2

[0057] A method for debugging the electrical hook extension amount of a vehicle hook, comprising the following steps:

[0058] S1: The docking hole 10 provided 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 the position, so that the axis of the mechanical hook head is as coincident as possible with the axis of the docking hole 10, thereby achieving preliminary positioning and fixing and providing a basis for subsequent accurate fixing.

[0059] The buckle 500 provided at the end of the first fixing part 50 is matched and clamped with the conical surface of the mechanical hook head. The buckle 500 generally has a certain elasticity, and when it is in contact with the conical surface of the mechanical hook head, the elasticity of the buckle 500 can cause a certain deformation, so that it is smoothly clamped in the corresponding position of the conical surface of the mechanical hook head. After clamping, the elastic restoring force of the buckle 500 will generate an inward clamping force, tightly fixing the mechanical hook head on the base 1, preventing the mechanical hook head from moving in the horizontal direction. The swing rod 510 at one end of the second fixing part 51 is connected with the rotating shaft of the fixed block 52, and the other end is provided with a protrusion 511. When the swing rod 510 is rotated, the swing rod 510 makes a circular motion around the rotating shaft, and the protrusion 511 is gradually brought close to the inner cavity surface of the mechanical hook head. With the continuous rotation of the swing rod 510, the mutual contact between the protrusion 511 and the inner cavity surface of the mechanical hook head, at this time, the friction between the protrusion 511 and the inner cavity surface of the mechanical hook head is sufficient, so as to fix the mechanical hook head in the vertical direction, preventing it from moving up and down or shaking. Through the joint action of the first fixing part 50 and the second fixing part 51, the mechanical hook head is firmly fixed on the base 1, providing a stable basis for subsequent debugging work.

[0060] S2, the driving unit 54 is connected with the fixed block 52, when the driving unit 54 is started according to the debugging requirement, the driving unit 54 will generate a driving force. The driving unit 54 includes a lead screw 540, and the lead screw 540 is threadedly connected with the fixed block 52, when the lead screw 540 is rotated under the driving of the motor or the handlebar, according to the principle of threaded transmission, the rotary motion of the lead screw 540 will be converted into the linear motion of the fixed block 52. The rotation direction of the lead screw 540 determines the moving direction of the fixed block 52, and by controlling the rotation number and speed of the lead screw 540, the moving distance and speed of the fixed block 52 can be accurately controlled. The fixed block 52 is connected with the first fixing part 50 and the second fixing part 51 respectively on both sides, when the fixed block 52 moves along the guide groove 56 under the driving of the driving unit 54, it will drive the first fixing part 50 and the second fixing part 51 to move together. Since the first fixing part 50 and the second fixing part 51 are fixedly connected with the mechanical hook head, the mechanical hook head will also move accordingly. The guide groove 56 provides accurate guidance for the movement of the fixed block 52, ensuring that the fixed block 52 can only move in the predetermined direction, thereby ensuring the accuracy and stability of the position adjustment of the mechanical hook head. In this way, the position of the mechanical hook head can be fine-tuned according to the actual debugging requirement, so that it reaches the ideal debugging position.

[0061] S3, the propulsion assembly 3 is installed on the base 1, and its propulsion end faces the base 1 and is connected with the docking assembly 4. When the propulsion assembly 3 is started, the push-pull rod 31 inside the propulsion assembly 3 will generate a pushing force, pushing the push-pull rod 31 to slide on the base 30. The push-pull rod 31 transmits the pushing force to the docking assembly 4 through the connecting rod 41, so that the docking assembly 4 moves towards the air path opening of the electric hook. The docking block 40 of the docking assembly 4 faces the air path opening of the electric hook, and the docking block 40 and the air path opening of the electric hook are of the same size and shape. When the docking assembly 4 moves forward under the pushing of the propulsion assembly 3, the docking block 40 will gradually dock with the air path opening of the electric hook. During the docking process, the docking block 40 will exert a forward pushing force on the electric hook. Due to the existence of certain connecting structure and movement relationship between the electric hook and the car hook, under the action of this pushing force, the electric hook will protrude forward.

[0062] S4, after the electric hook protrudes forward, the electric hook will have a certain protrusion amount compared with the car hook plane. A suitable measuring tool (such as a vernier caliper, a dial gauge, etc.) can be used to measure this protrusion amount. Place the measuring end of the measuring tool on the protruding part of the electric hook and the corresponding position of the car hook plane, and read the value on the measuring tool to obtain the protrusion amount of the electric hook. According to the measurement result, it can be judged whether the protrusion amount of the electric hook meets the design requirements and the debugging standard. If the protrusion amount does not meet the requirements, the propulsion amount of the propulsion assembly 3 can be adjusted, the position of the mechanical hook head can be readjusted, and other methods can be used for re-debugging until the protrusion amount of the electric hook reaches the qualified range, so as to complete the debugging work of the protrusion amount of the car hook and the electric hook.

[0063] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Any modification, equivalent change and modification of the above embodiment without departing from the technical solution of the present application, according to the technical essence of the present application, are still within the scope of the present application.
