DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other. The following will describe the present utility model in detail with reference to the drawings and in combination with the embodiments.

[0028] It should be pointed out that, unless otherwise specified, all technical and scientific terms used in the present application have the same meanings as those commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0029] In the present utility model, unless otherwise stated, the orientation words such as "upper, lower, top, bottom" are generally in reference to the directions shown in the drawings, or in reference to the vertical, perpendicular or gravitational directions of the components themselves; similarly, for the convenience of understanding and description, "inner, outer" refer to the inner and outer of the contours of the respective components themselves, but the above orientation words are not used to limit the present utility model.

[0030] In order to solve the problems of complex structure and poor versatility existing in the locomotive automatic coupler device in the prior art, the present utility model provides a locomotive automatic coupler device.

[0031] As Figures 1 to 6 shown, the locomotive automatic coupler device includes a base, a driving structure 2, a rotating arm 4, a lifting rod 5 and a control structure 3. The driving structure 2 is arranged on the base; the driving structure 2 is drivingly connected to one end of the rotating arm 4, and the driving structure 2 is used to drive the rotating arm 4 to rotate; the rotating arm 4 has a plurality of mounting areas, and the lifting rod 5 is selectively movably connected to one of the plurality of mounting areas; the control structure 3 is arranged on the driving structure 2 and is electrically connected to the driving structure 2.

[0032] By drivingly connecting the driving structure 2 to one end of the rotating arm 4 and arranging the control structure 3, the control structure 3 can control the operation timing and operation state of the driving structure 2, and then drive the rotating arm 4 to rotate to drive the lifting rod 5 to move, so as to realize the automatic operation of the locomotive coupler, effectively improving the efficiency and safety of locomotive operation, and reducing the errors and accident risks of manual operation. This device is particularly suitable for busy railway freight stations and can significantly improve the efficiency of cargo handling and unloading. During implementation, the application of the locomotive automatic coupler device significantly reduces the operation time and at the same time avoids potential safety hazards. Especially during night operations and under adverse weather conditions, the locomotive automatic coupler device avoids the risks of manual operation and ensures the continuity and safety of operations.

[0033] In addition, with the locomotive automatic coupler uncoupling device of the present application, when the locomotive acts as a booster in a multiple-unit connection mode, the main locomotive only needs to reduce the speed, and the crew of the booster locomotive can complete the separation of the booster locomotive from the main locomotive without getting off the locomotive; when the locomotive acts as a booster in a pulling and pushing mode, the main locomotive only needs to operate normally, and the crew of the booster locomotive can also complete the separation of the booster locomotive from the main locomotive without getting off the locomotive; this greatly reduces the labor intensity of personnel and improves the operation efficiency, especially in the harsh operating environments at night and in winter. It avoids potential safety hazards during the process of disconnecting the coupler after locomotive refueling.

[0034] In a specific embodiment of the present application, the drive structure 2 is a hydraulic rotary motor. The cylinder with a diameter of 80 mm can lift the coupler by a stroke of 170 mm. The hydraulic rotary motor drives the rotary arm 4 to move. After the rotary arm 4 lifts the coupler, it automatically drops to prepare for the next automatic coupling of the locomotive.

[0035] As Figure 1 and Figure 2 shown, at least a part of the rotary arm 4 is an arc-shaped arm section, and the end of the arc-shaped arm section far from the drive structure 2 is bent towards the direction close to the base. By setting at least a part of the rotary arm 4 as an arc-shaped arm section, the shape of at least a part of the rotary arm 4 is planned. Such a structural design enables the rotary arm 4 to fit the shape of the coupler more closely when rotating, improves the accuracy and stability of coupler uncoupling, and reduces damage to the coupler during the operation process. In railway freight transportation, this design is especially applicable to handling couplers with various complex and special shapes, improving the versatility of the device.

[0036] Specifically, the rotation direction of the rotary arm 4 includes the direction close to the base and the direction away from the base. That is to say, the rotary arm 4 can move up and down relative to the base. This two-way rotation ability enables the locomotive automatic coupler uncoupling device to adapt to the coupler uncoupling requirements in different directions. Whether operating from above or below the coupler, it can respond flexibly, greatly improving the flexibility and operation range of the locomotive automatic coupler uncoupling device.

[0037] As Figure 1 and Figure 2As shown, the rotating arm 4 includes two arm structures which are oppositely arranged and are both plate-shaped. Each arm structure consists of a circular plate 401 and an arc-shaped connecting plate 402. The circular plate 401 is drivingly connected to the driving structure 2. One side of the connecting plate 402 is connected to the outer peripheral edge of the circular plate 401, and the other side of the connecting plate 402 extends in a direction away from the circular plate 401. Specifically, the output shaft of the driving structure 2 is arranged on one of its side rotating end faces, and this rotating end face is perpendicular to the base. The circular plate 401 of one arm structure is drivingly connected to the output shaft of the driving structure 2 and fits against this rotating end face. The circular plate 401 of the other arm structure is oppositely arranged to the circular plate 401 of the above-mentioned one arm structure and is drivingly connected to the output shaft of the driving structure 2. The two circular plates 401 are concentrically arranged. The circular plate 401 and the connecting plate 402 of the same arm structure are integrally formed. Such an arrangement not only increases the structural strength of the rotating arm 4, but also enables the rotating arm 4 to remain stable when bearing a large load, improves the safety during the hook-lifting process, and is also beneficial to ensuring the service life of the rotating arm 4.

[0038] Specifically, the rotating arm 4 further includes a backing plate 405. The backing plate 405 is arranged between the two circular plates 401 so that the two arm structures are spaced apart, and a space for installing the lifting rod 5 is formed between the two connecting plates 402. The backing plate 405 is one or more, and the backing plate 405 is circular. The backing plate 405 is concentrically arranged with the two circular plates 401, and the centers of the backing plate 405 and the two circular plates 401 are connected to the output end of the driving structure 2. The addition of the backing plate 405 not only optimizes the internal structure of the rotating arm 4, but also provides a more stable installation environment for the lifting rod 5, reduces the shaking of the lifting rod 5 during the hook-lifting process, and improves the operation accuracy. Such an arrangement can ensure the accuracy of the hook-lifting operation and avoid the risk of damage to other structures caused by improper operation.

[0039] As Figure 1 and Figure 2 As shown, a plurality of mounting areas are arranged on the connecting plate 402 instead of on the circular plate 401. The plurality of mounting areas include at least one chute 404 and a plurality of slots 403. The plurality of slots 403 are spaced apart in a direction away from the at least one chute 404. One end of the lifting rod 5 is movably connected to the chute 404 or the slot 403. The chute 404 is an arc-shaped groove. Such an arrangement enables the lifting rod 5 to flexibly adjust its setting position according to different vehicle models and coupler types, enhancing the versatility and adaptability of the locomotive automatic hook-lifting device. In railway freight transportation, in the face of various locomotive models and couplers, this design can ensure that the device can quickly adapt and improve the operation efficiency.

[0040] In a specific embodiment of the present application, a chute 404 and a plurality of slots 403 are provided on each of the two connecting plates 402, and the chutes 404 on the two connecting plates 402 correspond to each other, and the plurality of slots 403 on the two connecting plates 402 correspond to each other one by one. Such a setting enables one end of the lifting rod 5 to be movably connected to a corresponding set of chutes 404 or a corresponding set of slots 403, which is more conducive to ensuring the connection stability between the lifting rod 5 and the connecting plate 402.

[0041] As Figure 5 and Figure 6 shown, the locomotive automatic coupler lifting device further includes a fixing pin 501, and one end of the lifting rod 5 is movably connected to the installation area through the fixing pin 501. Specifically, one end of the lifting rod 5 is movably connected to a corresponding set of chutes 404 or a corresponding set of slots 403 through the fixing pin 501. Such a setting enables the lifting rod 5 to be adjusted along the arc direction of the chute 404, and can also be arranged in a different set of corresponding slots 403 to adjust the position of the collar 504 to match different types of couplers, and at the same time enables the lifting rod 5 to swing up and down between the two connecting plates 402. In addition, one end of the lifting rod 5 is movably connected to the installation area through the fixing pin 501, which not only simplifies the installation and disassembly process of the lifting rod 5, but also ensures the connection stability of the lifting rod 5 in the working state, improving the reliability of the locomotive automatic coupler lifting device. In daily maintenance and repair, this design enables the staff to quickly replace the lifting rod 5, reducing the maintenance cost and time.

[0042] Furthermore, the fixing pin 501 facilitates standardized production and reduces the manufacturing cost. In case of emergency, such as when the lifting rod 5 is damaged, the staff can quickly replace it, reducing the operation delay caused by component replacement, improving the overall availability of the device, and being suitable for the efficient maintenance of large-scale railway transportation networks.

[0043] Specifically, the fixing pin 501 is movably connected to a corresponding set of chutes 404 or a corresponding set of slots 403. The fixing pin 501 has a through hole, and the extending direction of the through hole is perpendicular to the central axis of the corresponding set of chutes 404 or a set of slots 403. One end of the lifting rod 5 has a threaded section, and the end of the lifting rod 5 with the threaded section passes through the through hole and is connected to the fixing pin 501 through a nut 503. The end of the lifting rod 5 away from the fixing pin 501 has a collar 504.

[0044] Reference Figure 5As shown in the figure, one end of the lifting rod 5 with a threaded section passes through the through hole, and two nuts 503 are respectively arranged on the lifting rod 5 at the upper and lower ends of the through hole and are threadedly connected to the lifting rod 5, which can ensure the connection stability between the lifting rod 5 and the fixed pin 501 and ensure the reliable use of the lifting rod 5. In addition, such a setting not only ensures the firm connection between the lifting rod 5 and the rotating arm 4, but also increases the stability when the lifting rod 5 contacts the coupler through the design of the collar 504, reducing accidental slippage during the operation. In automated operation, this design can improve the stability and safety of the hook-lifting action, reducing operation interruptions and failure rates.

[0045] As Figure 4 shown, the base includes a bottom plate 101, the bottom plate 101 is located below the driving structure 2, the bottom plate 101 has a plurality of threaded holes 102, and the plurality of threaded holes 102 are arranged in an array. Specifically, the plurality of threaded holes 102 are distributed in the form of an equidistant rectangular dot matrix. The locomotive automatic hook-lifting device further includes a locomotive connecting plate 104, and the locomotive connecting plate 104 is connected to the surface of the bottom plate 101 facing away from the driving structure 2 through a locking member. The locomotive connecting plate 104 is in an "L" shape. Such a setting enables the locomotive automatic hook-lifting device to be connected to the locomotive through the locomotive connecting plate 104, which is beneficial to ensuring the firm connection between the device and the locomotive, and also increases the connection stability through the "L" shape design, reducing the shaking of the device under high-speed operation or complex track environments. In railway transportation, this design can ensure that even under harsh operating conditions, the locomotive automatic hook-lifting device can maintain stable operation, improving the safety and efficiency of the operation. At the same time, the locomotive connecting plate 104 can adjust the installation position on the bottom plate 101 and then be firmly connected through bolts 103, so that the connection position between the locomotive connecting plate 104 and the bottom plate 101 can be adjusted.

[0046] Specifically, the "L"-shaped locomotive connecting plate 104 is formed by connecting a long plate segment and a short plate segment. The short plate segment fits with the bottom plate 101, and the short plate segment has a plurality of threaded holes. The locomotive connecting plate 104 is connected to the bottom plate 101 by passing bolts 103 through the threaded holes of the short plate segment and the threaded holes 102 of the bottom plate 101. In a specific embodiment of the present application, a plurality of bolts 103 are provided, and the short plate segment is fixedly connected to the bottom plate 101 through a plurality of bolts 103.

[0047] As Figure 1 、 Figure 5 and Figure 6As shown in the figure, a plurality of threaded holes and a plurality of strip-shaped through slots 105 are provided on the locomotive connecting plate 104. Specifically, a plurality of threaded holes and a plurality of strip-shaped through slots 105 are provided on the long plate section. The plurality of strip-shaped through slots 105 are arranged at intervals, and the extending direction of the strip-shaped through slots 105 is perpendicular to the bottom plate 101. The plurality of threaded holes can be divided into two rows, and the plurality of threaded holes in the two rows are arranged at intervals. The two rows of threaded holes can be respectively arranged near both ends of the strip-shaped through slots 105 and can be set according to actual needs. This not only provides multiple installation methods for the device, but also increases the adjustment range of the device through the strip-shaped through slots 105, enabling the device to adapt to locomotives and tracks of different sizes, and improving the adaptability and operation flexibility of the device. In practical applications, this characteristic enables the locomotive automatic hook lifting device to be widely used in various railway transportation scenarios. Whether it is a standard track or a special track, it can be quickly adjusted to ensure the smooth progress of the operation.

[0048] It should be noted that in actual application, the electrical components in the locomotive automatic hook lifting device can be connected to their adapted power supply through wires, and a suitable control structure 3 should be selected according to the actual situation to meet the control requirements. For the specific connection method and control sequence, the electrical connection should be completed according to the sequence of the working order of each electrical component in the following working principle. The detailed connection means are well-known techniques in the art. The following mainly introduces the working principle and process, and no further description of the electrical control will be made.

[0049] During the application process, first, after the locomotive automatic hook lifting device receives a valid command from the positive and negative drivers, the control structure 3 of the locomotive automatic hook lifting device controls the driving structure 2 to operate, and the driving structure 2 drives the rotating arm 4 to move; then, the driving structure 2 drives the rotating arm to move upward at a certain speed until the hook is unhooked. At this time, the sensor installed at a specific position receives the instruction, and the control structure controls the driving structure 2 to stop driving; finally, the driving structure 2 drives the rotating arm to return to the initial position to prepare for the next hook operation.
