Description

Technical Field

[0001] This invention belongs to the field of train unloading technology, specifically relating to a positive hook device for a train tipping system. Background Technology

[0002] In train maintenance and cargo loading / unloading operations, it is often necessary to tilt, lift, or move train carriages. In these operations, the hook-up device is a key piece of equipment to ensure easy splicing of subsequent train carriages. The core function of the hook-up device is to accurately hold and restrain the hook on the vehicle through a movable supporting component, thereby effectively preventing the hook from swinging, rotating, or disengaging during lifting, tilting, or moving, ensuring that the hook body always maintains a stable and controllable posture.

[0003] Currently, existing hook-holding devices, to ensure accurate holding of the hook by the straightening and holding component, typically design the component to perform multiple degrees of freedom of movement (such as translation, lifting, and rotation). The traditional approach is to assign a separate drive source (such as a cylinder, hydraulic cylinder, or motor) to each degree of freedom. This "one degree of freedom, one drive" design directly results in a complex structure, large size, and high manufacturing cost for the entire device. Furthermore, in scenarios where multiple drive sources work together, when certain actions need to be executed in a strict sequence (e.g., the seat must unfold to create space before the straightening and holding component can move), coordinating the actions of multiple independent drive sources often presents significant control challenges and low reliability. Summary of the Invention

[0004] To address the aforementioned deficiencies or shortcomings, this invention provides a positive hook device for a train tipping system, aiming to solve the technical problems of existing positive hook devices having complex structures, high control difficulty and low reliability when performing multi-action coordinated control.

[0005] To achieve the above objectives, the present invention provides a positive hook device for a train tipper system. The positive hook device for a train tipper system includes a sliding module, a lower housing, a cover plate, a push plate assembly, and a drive mechanism. The lower housing is embedded in and slides on the sliding module. The cover plate can be accommodated in the lower housing and can be flipped relative to the lower housing. The push plate assembly can extend and retract in a direction perpendicular to the cover plate. The drive mechanism includes a drive motor, a tilting drive assembly, a push plate drive assembly, and a switching assembly. The tilting drive assembly is used to drive the cover plate to tilt, the push plate drive assembly is used to drive the push plate to extend and retract, and the switching assembly is configured to change the connection state of at least one of the tilting drive assembly and the push plate drive assembly, so that the drive motor controls the push plate to extend and retract or the cover plate to tilt under different connection states.

[0006] In this embodiment, the output end of the drive motor is connected to a first driving gear. The flipping drive assembly includes a rotating shaft, a first driven gear, and an end bracket. The first driven gear is fixedly sleeved on the outer circumference of the rotating shaft. The end bracket is located at one end of the cover plate near the lower housing and is connected to the rotating shaft. The first driving gear and the first driven gear mesh to drive the rotating shaft to rotate, thereby driving the cover plate to flip.

[0007] In this embodiment, the push plate drive assembly includes a first reversing gear, a second reversing gear, and a transmission rod. The first reversing gear is connected to the outer periphery of the rotating shaft, and the second reversing gear is connected to the end of the transmission rod and meshes with the first reversing gear. The transmission rod is connected to the push plate assembly and is used to drive the push plate assembly to extend and retract. The push plate assembly includes a push plate body and a push plate extension and retraction structure. The push plate extension and retraction structure works together with the transmission rod to convert the rotational force of the two reversing gears into the extension and retraction driving force of the push plate body.

[0008] In this embodiment, the switching component includes a sliding bracket, a fixed bracket, a first bushing, a tension spring, and a return spring. The sliding bracket is slidably connected to the groove corresponding to the stroke of the cover plate, so that it can slide and rise on the cover plate. The fixed bracket is fixedly connected to the cover plate. The first bushing is connected to the end of the transmission rod. The reversing gear is connected to the first bushing. One end of the tension spring is connected to the sliding bracket, and the other end is connected to the lower housing. One end of the return spring is connected to the first bushing through the sliding bracket, and the other end is connected to the fixed bracket. When the sliding bracket slides and rises relative to the groove of the cover plate, it causes the first reversing gear and the second reversing gear to mesh, or the first reversing gear and the second reversing gear to disengage.

[0009] In this embodiment, when the cover is in the closed state, the return spring overcomes the tension spring, causing the sliding bracket to be in the first extreme position. The first reversing gear and the second reversing gear disengage, and the drive motor can only control the shaft to rotate, so that the cover can flip. When the cover is in the open state with 90° relative to the lower housing, the tension spring overcomes the return spring, causing the sliding bracket to be in the second extreme position. The first reversing gear and the second reversing gear mesh, and the drive motor controls the shaft to rotate, so as to drive the push plate assembly and the cover to move together.

[0010] In this embodiment, a limiting structure is provided between the cover plate and the lower box. When the cover plate is flipped to the limit angle, the limiting structure stops the rotation of the cover plate.

[0011] In this embodiment, the first driven gear is a sector gear.

[0012] In this embodiment, the drive mechanism includes a gearbox, which is connected to the drive motor and is provided with a first drive gear and a second drive gear. The gearbox can selectively guide the power output from the drive motor to one of the first drive gear and the second drive gear through an internal power output switching module. The switching component is the power output switching module. The push plate drive assembly includes a second driven gear, a second reversing gear and a transmission rod. The second driven gear is connected to the outer circumference of the rotating shaft through a second bushing. The second reversing gear is connected to the end of the transmission rod and meshes with the second driven gear. The transmission rod is connected to the push plate assembly and is used to drive the push plate assembly to extend and retract.

[0013] In this embodiment, the gearbox is further provided with a first state for selectively guiding the power output of the drive motor to the first drive gear, and a second state including selectively guiding the power output of the drive motor to the second drive gear; in the first state, the output shaft of the drive motor and the first drive gear are connected in a transmission connection, and the drive motor is controlled to rotate the shaft so as to flip the cover plate; in the second state, the output shaft of the drive motor and the second drive gear are connected in a transmission connection, and the drive motor is controlled to rotate the transmission rod so as to drive the push plate assembly to move.

[0014] In this embodiment, the hook device for the train tipping system further includes a cleaning mechanism and an ultrasonic probe. The cleaning mechanism is connected to the lower housing. The ultrasonic probe is located on the side of the push plate assembly near the cover plate, and a corresponding hole for the ultrasonic probe is provided on the push plate assembly. When the cover plate is closed, the cleaning mechanism and the ultrasonic probe are in contact, so that the ultrasonic probe can be cleaned under drive.

[0015] Through the above technical solution, the positive hook device for a train tipping system provided in this embodiment of the invention has the following beneficial effects:

[0016] In this embodiment, the positive hook device uses a switching component to control the transmission connection state of the flipping drive component and the push plate drive component. Only one set of drive motors is needed to drive the cover plate and the push plate component. Compared with multiple drive sources, there are fewer control variables and the cumulative error generated during operation is lower, which greatly reduces the difficulty of control. Moreover, the torque of a single power source is directly distributed through the switching component, which fundamentally eliminates the asynchronous error between multiple drive sources. When some sequential compound coordinated actions need to be designed, the response is faster and the action is more accurate. In addition, compared with the hydraulic / pneumatic drive of transmission, the single motor solution eliminates the hydraulic cylinder / pneumatic cylinder and the matching solenoid valve, pressure sensor, etc., which greatly reduces the hardware cost and pipeline cost, and the structure is more compact, with a higher energy efficiency ratio and greater energy saving.

[0026] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0027] The hook device for a train tipper system of the present invention is described below with reference to the accompanying drawings.

[0028] This invention provides a positive hook device for a train tipper system, such as... Figures 1 to 4As shown, the hook device for the train tipper system includes a sliding module 11, a lower box 12, a cover plate 2, a push plate assembly 3, and a drive mechanism.

[0029] The lower housing 12 is embedded in the sliding module 11 and can slide on the sliding module 11. When the hook device is assembled on the train tipper system, the sliding direction of the lower housing 12 can be along the direction in which the train car 6 enters and exits the train tipper system. Of course, the lower housing 12 can also slide in other directions. The purpose of moving the lower housing 12 is to move the cover plate 2 and the push plate assembly 3 to a suitable position, thereby facilitating the subsequent precise contact of the push plate assembly 3 with the hook on the train car 6. The movement path of the lower housing 12 preferably avoids the entry and exit path of the train car 6 in and out of the train tipper system, that is, the lower housing 12 slides to any position on the sliding module 11 without affecting the entry and exit of the train car 6 in and out of the train tipper system.

[0030] The lower housing 12 has a receiving cavity 12a with an opening. The cover plate 2 can be flipped relative to the lower housing 12 to be flipped out or hidden inside the lower housing 12. When the cover plate 2 is rotated to be hidden inside the lower housing 12, the entire positive hook device is in an avoidance posture, that is, the cover plate 2 does not affect the train carriage 6 entering or leaving the train tipper system when the lower housing 12 slides to any position of the sliding module 11.

[0031] The push plate assembly 3 can extend and retract in a direction perpendicular to the cover plate, which here refers to the direction perpendicular to the surface of the cover plate 2. When the cover plate 2 is flipped out from the lower housing 12 and rotated to a specific position, by adjusting the position of the lower housing 12, the cover plate 2 and the hook can be aligned in the cover plate direction. At this time, by controlling the push plate assembly 3 to extend, the push plate assembly 3 can be brought into contact with the hook.

[0032] The drive mechanism includes a drive motor 41, a flip drive assembly 42, a push plate drive assembly 43, and a switching assembly 44. The flip drive assembly 42 is used to drive the cover plate 2 to flip, the push plate drive assembly 43 is used to drive the push plate to extend and retract, and the switching assembly 44 is configured to change the connection state of at least one of the flip drive assembly 42 and the push plate drive assembly 43, so that the drive motor 41 controls the extension and retraction of the push plate assembly 3 and the flipping of the cover plate 2 in different connection states.

[0033] Combination Figure 1 and Figure 5As shown, when using this device, the lower housing 12 is first moved to a position to avoid interference with surrounding components and the train carriage 6 when the cover plate 2 is unfolded. After moving to this position, the drive motor 41 is connected to the tilting drive assembly 42 via the switching component 44, allowing the cover plate 2 to unfold. After the cover plate 2 is unfolded, the lower housing 12 is moved to a suitable position so that the push plate assembly 3 is aligned with the hook in a direction perpendicular to the cover plate 2. At this point, the positioning action of the push plate assembly 3 before straightening is completed. After the push plate assembly 3 is aligned with the hook, the drive motor 41 is connected to the push plate drive assembly 43 via the switching component 44, allowing the push plate drive assembly 43 to extend and abut against the straightening contact surface of the hook. In this way, when the train tilting system causes the train carriage 6 to tilt, the push plate assembly 3 can ensure that the hook's posture remains unchanged.

[0034] In summary, this device uses a switching component 44 to control the transmission connection state of the flipping drive component 42 and the push plate drive component 43. Only one set of drive motors 41 is needed to drive the cover plate 2 and the push plate component 3. Compared with multiple drive sources, there are fewer control variables and the cumulative error generated during operation is lower, which greatly reduces the difficulty of control. Moreover, the torque of a single power source is directly distributed through the switching component 44, which fundamentally eliminates the asynchronous error between multiple drive sources. When some sequential compound coordinated actions need to be designed, the response is faster and the action is more accurate. In addition, compared with the hydraulic / pneumatic drive of transmission, the single motor solution eliminates the hydraulic cylinder / pneumatic cylinder and the matching solenoid valve, pressure sensor, etc., which greatly reduces the hardware cost and pipeline cost, making the structure more compact, the energy efficiency ratio higher, and more energy-saving.

[0035] In this embodiment, the sliding module 11 may include a guide (such as a guide rail or guide groove) for guiding the lower housing 12 to slide, and a sliding drive assembly for driving the lower housing 12 to slide on the guide. The sliding drive assembly may be a motor screw, a telescopic cylinder, a winch, etc.

[0036] like Figure 2 and Figure 4 As shown, in this embodiment, the flipping drive assembly 42 may include a rotating shaft 421, a first driven gear 422, and an end bracket 423. The first driven gear 422 is fixedly sleeved on the outer periphery of the rotating shaft 421, and the end bracket 423 is disposed at one end of the cover plate 2 near the lower housing 12 and connected to the rotating shaft 421. The cover plate 2 and the end bracket 423 may be integrally disposed or connected by a connector. The cover plate 2 is hinged on the lower housing 12 through the rotating shaft 421 and the end bracket 423.

[0037] The drive motor 41 is connected to the first drive gear 451 via a transmission connection. This transmission connection can be as follows: Figure 2 The first drive gear 451 shown is directly connected to the output shaft of the drive motor 41, or as... Figure 4 The two shown are connected by a multi-stage transmission. The first driving gear 451 and the first driven gear 422 mesh, and the first driving gear 451 is driven to rotate by the drive motor 41, which can drive the rotating shaft 421 to rotate, thereby driving the cover plate 2 to flip relative to the lower box 12.

[0038] To achieve the driving of pusher assembly 3, such as Figure 1 and Figure 2 As shown, in one embodiment, the push plate assembly 3 includes a push plate body 31 and a push plate telescopic structure 32. The push plate drive assembly 43 may include a first reversing gear 431, a second reversing gear 432, and a transmission rod 433. The first reversing gear 431 is connected to the outer periphery of the rotating shaft 421. The second reversing gear 432 is connected to the end of the transmission rod 433 and meshes with the first reversing gear 431. The transmission rod 433 is connected to the push plate telescopic structure 32 and is used to drive the push plate body 31 to extend and retract. The push plate telescopic structure 32 and the transmission rod 433 work together to convert the rotational force of the second reversing gear 432 into the extension and retraction driving force of the push plate body 31.

[0039] When the shaft 421 rotates, in addition to the cover plate 2 moving, the first reversing gear 431 also rotates. The power of the first reversing gear 431 is transmitted sequentially through the second reversing gear 432, the transmission rod 433, and the push plate telescopic structure 32 to the push plate body 31, thereby driving the push plate body 31 to extend. That is, in this embodiment, by fixing the first reversing gear 431 onto the shaft 421, the cover plate 2 and the push plate assembly 3 can be driven together.

[0040] like Figure 1 As shown, in this embodiment, the push plate telescopic structure 32 can be a scissor arm assembly, and the transmission rod 433 can be a lead screw. The lead screw drives the movable arm of the scissor arm assembly to move, thereby causing the scissor arm to drive the push plate body 31 to extend.

[0041] In this embodiment, the push plate telescopic structure 32 can also be a telescopic pin, and the transmission rod 433 can still be a lead screw. When the lead screw moves linearly, the telescopic pin can be driven to extend through the wedge structure, thereby pushing the push plate body 31 to extend.

[0042] In this embodiment, the push plate telescopic structure 32 can also be a pulley tensioning group similar to that inside the telescopic arm of engineering machinery.

[0043] Furthermore, in order to control the connection states of the flip drive assembly 42 and the push plate drive assembly 43 with the drive motor 41 respectively, such as Figure 1 and Figure 2As shown, in this embodiment, the switching component 44 may include a sliding bracket 441, a fixed bracket 442, a first bushing 443, a tension spring 444, and a return spring 445. The sliding bracket 441 is slidably connected to the slide groove of the cover plate 2 corresponding to the stroke, so that it can slide and rise on the cover plate 2. The fixed bracket 442 is fixedly connected to the cover plate 2. The first bushing 443 is connected to the end of the transmission rod 433. The reversing gear is connected to the first bushing 443. One end of the tension spring 444 is connected to the sliding bracket 441, and the other end is connected to the lower housing 12. One end of the return spring 445 is connected to the first bushing 443 through the sliding bracket, and the other end is connected to the fixed bracket 442.

[0044] When the cover plate 2 is in the closed state, the return spring 445 overcomes the tension spring 444, causing the sliding bracket 441 to be in the first extreme position. In the first extreme position, the first reversing gear 431 and the second reversing gear 432 are disengaged. At this time, the drive motor 41 can only control the rotating shaft 421 to rotate, so that the cover plate 2 can be flipped. When the cover plate 2 is in the open extreme position, the tension spring 444 overcomes the return spring 445, causing the sliding bracket 441 to be in the second extreme position. In the second extreme position, the first reversing gear 431 and the second reversing gear 432 are engaged. When the drive motor 41 controls the rotating shaft 421 to rotate, the push plate assembly 3 and the cover plate 2 move together.

[0045] Specifically, when the cover plate 2 is unfolded, the tension spring 444 is stretched. Under the action of the tension spring 444, the sliding bracket 441 will overcome the force of the return spring 445 and move towards the bottom edge of the cover plate 2 (towards the end near the lower housing 12), causing the position of the second reversing gear 432 to drop. When the cover plate 2 is unfolded to a certain critical position, the second reversing gear 432 will engage with the first reversing gear 431. At this time, the power of the rotating shaft 421 can be transmitted to the push plate assembly 3 in sequence through the first reversing gear 431 and the second reversing gear 432, so as to realize the extension drive of the push plate assembly 3 when the cover plate 2 is unfolded.

[0046] In this embodiment, through the cooperation of the tension spring 444 and the sliding bracket 441, the push plate assembly 3 can only start to move when the cover plate 2 is opened to a certain degree. This realizes the coordinated compound action control of the device, which is "the cover plate 2 moves first, and then the cover plate 2 and the push plate assembly 3 move together". By designing this action, when the stroke of the push plate assembly 3 is inconsistent with the stroke of the cover plate 2, this coordinated action can prevent the push plate assembly 3 from over-extending, or can prevent the cover plate 2 from being unable to open due to the insufficient space allowed for the push plate assembly 3 to extend.

[0047] When the cover plate 2 rotates into the lower housing 12, both the tension spring 444 and the return spring 445 gradually return to their original positions. Due to the retraction of the return spring 445, the sliding bracket 441 moves towards the top edge of the cover plate 2 (i.e., the end of the cover plate 2 away from the lower housing 12), causing the position of the second reversing gear 432 to gradually rise. Before the second reversing gear 432 separates from the first reversing gear 431, the cover plate 2 rotates into the lower housing 12, and the push plate assembly 3 retracts synchronously. When the cover plate 2 flips downward to a certain critical position, the second reversing gear 432 separates from the first reversing gear 431. At this time, the rotation of the shaft 421 will only drive the cover plate 2 to move, and the push plate assembly 3 will stop moving.

[0048] In this embodiment, through the cooperation of the return spring 445 and the sliding bracket 441, the push plate assembly 3 can stop moving when the cover plate 2 is closed to a certain extent, and only the cover plate 2 moves thereafter. Similarly, by designing this action, when the stroke of the push plate assembly 3 is inconsistent with the stroke of the cover plate 2, excessive retraction of the push plate assembly 3 can be avoided.

[0049] In this embodiment, a limiting structure is provided between the cover plate 2 and the lower housing 12. When the cover plate 2 is rotated to its limit angle, the limiting structure prevents rotation and restricts the cover plate 2. The limiting structure can be a limiting block provided on the cover plate 2, the lower housing 12, or the rotating shaft 421. Through the limiting mechanism, the maximum unfolding angle of the cover plate 2 can be limited mechanically to avoid the push plate assembly 3 from over-extending or over-retracting, thereby protecting the device.

[0050] In this embodiment, the maximum opening angle of the cover plate 2 can be 90° perpendicular to the ground.

[0051] To protect the device, in this embodiment, the first driven gear 422 can also be a sector gear. By setting the first driven gear 422 to a sector shape, when the first driving gear 451 meshes with the sector edge of the first driven gear 422, the cover plate 2 will be unable to rotate further. By making the first driven gear 422 a sector gear, the cover plate 2 is limited at the transmission level.

[0052] In this embodiment, both the first reversing gear 431 and the second reversing gear 432 can be bevel gears.

[0053] In this embodiment, in order to achieve power switching control, in addition to using the sliding bracket 441 in conjunction with the tension spring 444 or the return spring 445, other methods can also be used to achieve the clutch control of the first reversing gear 431 and the second reversing gear 432.

[0054] To achieve the driving of pusher assembly 3, such as Figure 3 and Figure 4As shown, in another embodiment, the drive mechanism may include a gearbox 45, which is connected to a drive motor 41. A first drive gear 451 is one of the output ends of the gearbox 45, and the gearbox 45 also includes a second drive gear 452 as the other output end. The first drive gear 451 meshes with a first driven gear 422. The gearbox 45 is internally provided with a power output switching module (such as a clutch). The power output switching module is used to control the gearbox 45 to selectively direct the power output from the drive motor 41 to one of the first drive gear 451 and the second drive gear 452. The switching component 44 is the power output switching module within the gearbox 45.

[0055] The push plate drive assembly 43 includes a second driven gear 434, a second reversing gear 432, and a transmission rod 433. The second driven gear 434 is connected to the outer periphery of the rotating shaft 421 through a second bushing 435. Through the second bushing 435, the first reversing gear 431 can rotate freely relative to the rotating shaft 421. The second reversing gear 432 is connected to the end of the transmission rod 433 and meshes with the second driven gear 434. The transmission rod 433 is connected to the push plate assembly 3 and is used to drive the push plate assembly 3 to extend and retract.

[0056] In this embodiment, the gearbox 45 is further provided with a first state for selectively guiding the power output from the drive motor 41 to the first drive gear 451, and a second state including selectively guiding the power output from the drive motor 41 to the second drive gear 452.

[0057] In the first state, the output shaft of the drive motor 41 is connected to the first drive gear 451. By controlling the drive motor 41, the rotating shaft 421 is rotated, so that the cover plate 2 is flipped.

[0058] In the second state, the output shaft of the drive motor 41 is connected to the second drive gear 452. By controlling the drive motor 41, the transmission rod is rotated to drive the push plate assembly 3 to move.

[0059] Specifically, when the gearbox 45 switches to the output of the first drive gear 451, the power output of the drive motor 41 is transmitted sequentially through the first drive gear 451 and the first driven gear 422 to the rotating shaft 421, thereby driving the cover plate 2 to flip. When the gearbox 45 switches to the output of the second drive gear 452, the power output of the drive motor 41 is transmitted sequentially through the second drive gear 452, the second driven gear 434, the second reversing gear 432, and the transmission rod 433, thereby driving the push plate assembly 3 to extend.

[0060] Of course, the gearbox 45 can also have a third state, in which the first drive gear 451 and the second drive gear 452 simultaneously output to the outside.

[0061] It is understood that in this embodiment, only the timing of the state switching of the gearbox 45 needs to be controlled to achieve the control of the movement timing of the device when the cover plate 2 moves alone, the push plate assembly 3 moves alone, and the cover plate 2 and the push plate assembly 3 move simultaneously.

[0062] like Figure 1 As shown, in this embodiment, the hook-up device for the train tipper system further includes a cleaning mechanism 51 and an ultrasonic probe 52. The cleaning mechanism 51 is connected to the lower housing 12. The ultrasonic probe 52 is located on the side of the push plate assembly 3 near the cover plate 2, and a corresponding hole for the ultrasonic probe 52 is provided on the push plate assembly 3. The ultrasonic probe 52 facilitates the determination of the distance between the push plate assembly 3 and the hook when straightening it, preventing the push plate assembly 3 from overextending and causing excessive pressure and damage. The cleaning mechanism 51 is mainly used to clean the ultrasonic probe 52 to prevent the sound wave generating end of the ultrasonic probe 52 from being covered by dust. When the cover plate 2 is closed, the cleaning mechanism 51 and the ultrasonic probe 52 are in contact, allowing the ultrasonic probe 52 to be cleaned under drive. That is, the cleaning of the ultrasonic probe 52 occurs when the cover plate 2 is closed.
