Detailed Implementation

[0052] The technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0053] The components of the embodiments of this application described and shown in the accompanying drawings can typically be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0054] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description. In the description of this application, it should be noted that unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joint" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components.

[0055] The following reference Figures 1 to 25 This application describes a push-type positive hook system according to some embodiments.

[0056] See Figures 1 to 25 As shown, an embodiment of this application provides a push-type positive hook system, including: an auxiliary moving device 100 and a push-type positive hook device 200; wherein, the push-type positive hook device 200 includes a positive hook drive device 21, a transmission mechanism, a positive hook base 22, an outer tube 23, an inner tube 24, a chain mechanism 25, and a positive hook assembly 26; the positive hook base 22 is installed on the auxiliary moving device 100; the positive hook base 22 forms an installation cavity and openings disposed on both sides of the installation cavity along a first preset direction; the inner tube 24 and the outer tube 23 are both movably inserted into the installation cavity along the first preset direction, and a portion of the structure of the inner tube 24 is disposed inside the outer tube 23; the positive hook assembly 26 is connected to one end of the inner tube 24 extending out of the positive hook base 22;

[0057] The chain mechanism 25 includes a first sprocket 251, a second sprocket 252, and a chain 253. The first sprocket 251 and the second sprocket 252 are arranged sequentially at intervals along a first preset direction and are rotatably connected to the outer tube 23. The chain 253 is engaged with the first sprocket 251 and the second sprocket 252 respectively. The chain 253 is connected to the inner tube 24 and the hook base 22 respectively. The hook drive device 21 is connected to the outer tube 23 through a transmission mechanism and is used to drive the outer tube 23 to move the inner tube 24 along the first preset direction.

[0058] In this embodiment, the working process of the push-type positive hook system provided in this application is roughly as follows: First, the auxiliary moving device 100 drives the positive hook driving device to move to the working position. Then, the positive hook driving device 21 drives the outer tube 23 to move along the first preset direction through the transmission mechanism. Since the first sprocket 251 and the second sprocket 252 are both connected to the outer tube 23, and the chain 253 is simultaneously connected to the positive hook base 22 and the inner tube 24, the first sprocket 251 and the second sprocket 252 will force the chain 253 to rotate during the process of following the movement of the outer tube 23, thereby driving the inner tube 24 connected to the chain 253 to also move along the first preset direction, thereby driving the positive hook assembly 26 connected to the inner tube 24 to move, thus facilitating the straightening of the car coupler.

[0059] It is evident that the push-type coupler system provided in this application can achieve automatic coupler alignment without manual operation, saving time and effort, greatly improving work efficiency, freeing up labor, and posing no safety hazards to workers.

[0060] Furthermore, preferably, both the outer fitting 23 and the inner fitting 24 can be square fittings, resulting in a more stable structure. They also have flat mounting sides, facilitating the installation of other components, and their simple structure makes them easy to manufacture. Of course, this is not the only option; the shapes of the outer fitting 23 and the inner fitting 24 can be designed according to actual needs.

[0061] Furthermore, preferably, the length directions of the outer tube 23 and the inner tube 24 are consistent with the first preset direction. Of course, this is not the only option; the design can be tailored to specific needs. Both the outer tube 23 and the inner tube 24 are hollow internally and open at both ends along the first preset direction. Again, this is not the only option; the design can be tailored to specific needs. The first preset direction can be horizontal, and so on. Of course, this is not the only option; the design can be tailored to specific needs. Both the first sprocket 251 and the second sprocket 252 are equipped with fixed seats 223, and the shafts of the first sprocket 251 and the second sprocket 252 are mounted between the corresponding fixed seats 223. The fixed seats 223 on both sides are fixed to the outer tube 23, and the first sprocket 251 and the second sprocket 252 can rotate freely. Of course, this is not the only option; the design can be tailored to specific needs. The outer cover 224 is fixed to the outside of the hook base 22. The outer cover 224 can be composed of a flat plate. Of course, this is not the only option; the outer cover 224 may not be provided. The hook drive device 21 is a motor. Of course, this is not the only option.

[0062] In one embodiment of this application, preferably, as shown below, Figures 3 to 10As shown, the auxiliary moving device 100 includes: a main support member 11, a moving member 12, a moving drive device 13, a first gear 14, a first rack 15, and a leveling assembly 16; wherein, the moving member 12 is slidably connected to the main support member 11; the fixed end of the moving drive device 13 is fixed to the moving member 12, and the driving end of the moving drive device 13 is connected to the first gear 14; the first rack 15 is fixed to the main support member 11, and the first gear 14 meshes with the first rack 15; along the moving direction perpendicular to the moving member 12, leveling assemblies 16 are provided on opposite sides of the main support member 11, and each side of the main support member 11 is mounted on the ground through the leveling assembly 16, which is used to adjust the flatness of the main support member 11; a positive hook base 22 is mounted on the moving member 12.

[0063] In this embodiment, the auxiliary moving device 100 is used roughly as follows: First, multiple leveling components 16 are installed on the ground on opposite sides of the two rails. Then, the main support component 11, which integrates the moving component 12, the moving drive device 13, the first gear 14, and the first rack 15, is placed on the multiple leveling components 16 on the left and right sides. Then, the moving drive device 13 drives the first gear 14 to rotate, thereby allowing the first gear 14 to move along the first rack 15, which in turn drives the moving component 12 and the jacking hook device 200 on it to move to the designated working position. Of course, the above steps are just an example and can be adjusted according to actual needs.

[0064] It is evident that this auxiliary moving device 100 is set up independently of the railway track and no longer shares the track with the shunting locomotive. In other words, it adopts an independent track design, which is suitable for a variety of applications and occupies little space.

[0065] Furthermore, preferably, the moving drive device 13 is a motor, but of course, it is not limited to this.

[0066] In one embodiment of this application, preferably, as shown below, Figure 10 As shown, the leveling assembly 16 includes a first leveling plate 161, a second leveling plate 162, a stud 163, and a nut 164. The first leveling plate 161 is installed on the ground. The stud 163 is arranged vertically and fixed to the first leveling plate 161. The second leveling plate 162 is arranged above the first leveling plate 161, and the second leveling plate 162 has a mounting through hole. The stud 163 passes through the mounting through hole, and the nut 164 is threadedly connected to the stud 163. Nuts 164 are provided on both the upper and lower surfaces of the second leveling plate 162 to lock the second leveling plate 162. The main support member 11 is arranged on the upper surface of the second leveling plate 162, and the two are connected.

[0067] In this embodiment, the first adjusting plate 161 can be fixed to the ground by bolts or the like. The height of the second adjusting plate 162 can be adjusted by two nuts 164 at the top and bottom of the second adjusting plate 162. Since the main support is placed on the upper surface of the second adjusting plate 162, the level of the second adjusting plate 162 can be adjusted to ensure the level of the main support component 11 and avoid problems such as tilting of the main support component 11. Ultimately, the working accuracy of the jacking hook device 200 installed on the moving component 12 can be guaranteed.

[0068] Furthermore, preferably, the main support member 11 and the second adjusting plate 162 can be connected by welding. Of course, this is not the only option; other connection methods can be selected according to actual needs.

[0070] In this embodiment, after the second adjusting plate 162 is adjusted, two nuts 164 can be fixed, and reinforcing bolts 165 can be installed on the first adjusting plate 161 and the second adjusting plate 162 for reinforcement. When the second adjusting plate 162 needs to be readjusted, the reinforcing bolts 165 can be removed from the first adjusting plate 161 and the second adjusting plate 162, and then the nuts 164 can be adjusted. Of course, the reinforcing bolts 165 can also be omitted, depending on the actual needs.

[0071] Furthermore, preferably, the number of reinforcing bolts 165 can be two, and they are respectively set on opposite sides of the stud 163. Of course, it is not limited to this. Only one can be set, or no reinforcing bolt 165 can be set. The specific choice depends on the needs.

[0072] In one embodiment of this application, preferably, as shown below, Figure 4 and Figure 5 As shown, the auxiliary moving device 100 also includes an auxiliary slide rail 17, which is disposed on the main support member 11 and along the vertical direction, and is located below the moving member 12. The moving member 12 is provided with an auxiliary slider 18, and the auxiliary slider 18 is slidably connected to the auxiliary slide rail 17. There are two auxiliary slide rails 17, which are spaced apart along a length direction perpendicular to the length of the auxiliary slide rail 17. In this embodiment, the sliding connection between the moving member 12 and the main support member 11 is achieved through the cooperation of the slider and the slide rail, and the structure of the slider and the slide rail is stable and has a longer service life.

[0073] In one embodiment of this application, preferably, as shown below, Figure 3 As shown, the auxiliary moving device 100 also includes a first accordion cover (not shown) and a second accordion cover 111; wherein, one end of the first accordion cover is connected to one end of the main support member 11, and the other end of the first accordion cover is connected to one end of the moving member 12; one end of the second accordion cover 111 is connected to the other end of the main support member 11, and the other end of the second accordion cover 111 is connected to the end of the moving member 12 that is connected to the first accordion cover, and the first accordion cover covering the moving member 12 has an opening for clearance.

[0074] In this embodiment, as the movable component 12 moves along the auxiliary slide rail 17, it pulls the first accordion cover to unfold along the auxiliary slide rail 17 and pushes the second accordion cover 111 to retract, or it pushes the first accordion cover to retract and pulls the second accordion cover 111 to unfold along the auxiliary slide rail 17, thereby covering the auxiliary slide rail 7 and preventing it from being exposed, thus protecting the auxiliary slide rail 7. Of course, the accordion cover may not be provided, depending on the actual needs.

[0075] In one embodiment of this application, preferably, as shown below, Figure 1 As shown, the auxiliary moving device 100 also includes a lubricating oil tank 113, a diverter valve, and a pressure detection component. The lubricating oil tank 113 and the diverter valve are both located on the moving component 12. The lubricating oil tank 113 is connected to the diverter valve via a pipeline. The two outlet ends of the diverter valve are each equipped with a pipeline, and the two pipelines at the two outlet ends of the diverter valve extend to the two auxiliary sliders 18 respectively. The pressure detection component is located on the pipeline connecting the lubricating oil tank 113 and the diverter valve. It should be noted that the diverter valve and the pressure detection component are not shown in the figure.

[0076] In this embodiment, a diversion valve is used to distribute the lubricating oil flowing out of the lubricating oil tank 113 to the two auxiliary sliders 18, so that the auxiliary sliders 18 and the auxiliary slide rails 17 in contact with the auxiliary sliders 18 are always lubricated, avoiding problems such as jamming, making the structure more reliable. Moreover, pressure detection components such as pressure sensors can be used to monitor the pressure of the oil at all times, making it more controllable.

[0103] In this embodiment, the inner tube 24 and the outer tube 23 are slidably connected, serving as a sliding guide while also preventing interference. It should be noted that, to distinguish the slide rail and slider from those in other locations, the slide rail here is referred to as the second slide rail 213, and the slider here as the second slider 214. Preferably, the second slide rail 213 is fixed to the outer tube 23, and the second slider 214 is fixed to the inner tube 24. However, this is not a limitation; the inner tube 24 can also be fixed to the outer tube 23, and the second slide rail 213 can be fixed to the inner tube 24.

[0104] In one embodiment of this application, preferably, as shown below, Figure 14 As shown, the top-pushing hook device also includes a trigger sensor 215 and a trigger component 216; wherein, one of the trigger sensor 215 and the trigger component 216 is disposed on the outer tube 23, and the other is disposed on the hook base 22, and the trigger sensor 215 and the trigger component 216 are arranged sequentially at intervals along a first preset direction, and when the outer tube 23 moves along the first preset direction toward the hook to be hooked to the first limit position, the trigger component 216 is used to trigger the trigger sensor 215 so that the outer tube 23 stops moving forward.

[0105] In this embodiment, when the outer tube 23 moves along the first preset direction toward the hook to be hooked to the first limit position, the triggering component 216 triggers the triggering sensor 215, thereby obtaining that the outer tube 23 has moved to the limit position, which in turn stops the drive device, preventing the outer tube 23 and the inner tube 24 from continuing to move forward, thus avoiding the slider from disengaging from the slide rail as described below, which could lead to structural failure. Of course, this is not limited to the above, and other layouts can also be used, for example: the triggering sensor 215 is set on the outer tube 23, and the triggering component 216 is set on the hook base 22, depending on actual needs. Further, preferably, the triggering component 216 can be an L-shaped metal part, but it is not limited to this, and can be designed according to actual needs.

[0107] In this embodiment, the aforementioned trigger sensor 215 and trigger member 216 serve as the first level of limiting. When the first level of limiting fails, a second level of limiting can be used. When the first level of limiting fails, the outer tube 23 and inner tube 24 will continue to move forward. When they reach the second limit position, the first limiting member 217 will contact the inner tube 24, thereby forcing the outer tube 23 and inner tube 24 to stop moving forward. It is evident that this application provides dual limiting, making it safer and more reliable. Of course, it is not limited to this; only one limiting structure can be provided, such as only the aforementioned limiting structure of trigger sensor 215 and trigger member 216, or only the aforementioned limiting structure of first limiting member 217 and second limiting member 218.

[0111] In this embodiment, the positive hook drive device 21 drives the gear to rotate, and the second gear 220 drives the second rack 221 to move. Since the second rack 221 is fixed on the outer tube 23, it drives the outer tube 23 to move. Of course, the transmission mechanism is not limited to the above and can be selected according to actual needs.

[0112] In one embodiment of this application, preferably, as shown below, Figure 11 As shown, the top-pushing hook device also includes a bottom support member 222, which is installed on the top of the moving member 12 of the auxiliary moving device 100, and the hook base 22 is fixed to the top of the bottom support member 222.
