Technical Field

[0001] The utility model relates to the technical field of locomotive coupler uncoupling, in particular to an automatic locomotive coupler uncoupling device. Background Technique

[0002] As an important means of transportation in modern society, railway locomotive transportation is widely used; the freight car body of a locomotive is the main carrier for railway freight transportation, and the freight car bodies are usually connected by couplers. The main functions of the coupler are to realize the connection and separation between freight car bodies, and at the same time transmit traction force and braking force. The number and weight of freight car bodies can be increased or decreased according to the quantity and weight of goods, so as to meet the requirements of the safety, stability and economy of freight transportation.

[0003] In the related art, when uncoupling a locomotive coupler, the manual uncoupling method is usually adopted. On the one hand, the complexity of uncoupling leads to a large manual labor intensity and a slow uncoupling speed, which affects the transportation efficiency of railway locomotives; on the other hand, there are certain safety risks in manual uncoupling. If the operation is improper, it may cause injuries to operators or damage to equipment. Therefore, there is an urgent need for an automatic locomotive coupler uncoupling device to reduce manual intervention, improve the uncoupling efficiency, and meet the needs of modern railway transportation.

[0038] In order to make the purpose, technical solution and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model, that is, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Usually, the components of the embodiments of the present utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] Therefore, the detailed description of the embodiments of the present utility model provided in the drawings below is not intended to limit the scope of the claimed present utility model, but merely represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0040] As Figures 1-4 shown in the embodiment of the present utility model, an automatic uncoupling device for a locomotive coupler includes: a locomotive end plate 1, on which several coupler seats 2 are provided; a coupler rod 3 passing through the through holes of the coupler seats 2; a lifting hook driving rod 4 movably arranged on the coupler rod 3, a lifting hook driven rod 5 fixedly arranged on the coupler rod 3, and the lifting hook driven rod 5 is arranged between the lifting hook driving rods 4; an electric push rod 6 is arranged at the bottom of the lifting hook driving rod 4; a lifting hook chain 7 is arranged in the middle of the coupler rod 3, and a coupler pin 8 is arranged at the bottom of the lifting hook chain 7; an electronic control module 9 is arranged on the locomotive end plate 1.

[0041] When manually unhooking, the hook rod 3 is held and rotated 90° counterclockwise. At this time, the hook lifting driven rod 5 welded on the hook rod 3 rotates idly relative to the hook lifting active rod 4. The hook rod 3 lifts the hook pin 8 through the hook lifting chain 7, thereby manually unhooking the locomotive hook, and there is no additional resistance in the process.

[0042] When the hook is automatically unhooked, after the electronic control module 9 receives the command, the electric push rod 6 is lifted upward, driving the hook lifting active rod 4 to rotate counterclockwise, and then the hook lifting active rod 4 drives the hook lifting driven rod 5 on the hook rod 3 to rotate, thereby driving the hook lifting chain 7 to lift the hook pin 8, completing the automatic unhooking of the locomotive hook; after lifting into place, the electric push rod 6 is retracted downward, driving the hook lifting active rod 4 to return to the initial position. In this process, the hook lifting driven rod 5 and the hook rod 3 fall back to the initial position under the action of gravity.

[0043] Specifically, the locomotive coupler automatic unhooking device can effectively unhook the locomotive coupler manually or automatically, and through the automatic unhooking function, it greatly reduces manual intervention, avoids manual operation risks, reduces the possibility of accidents, ensures that the locomotive coupler maintains stability during the unhooking process, and ensures the smooth unhooking. Compared with traditional unhooking methods, it effectively improves the unhooking efficiency and safety, and can meet the needs of modern railway transportation.

[0045] Specifically, since the retaining rings 10 are respectively provided on the coupler rods 3 between several adjacent coupler seats 2, the relative positions of the left and right ends of the coupler rods 3 can be effectively limited to prevent the coupler rods 3 from being displaced too much and affecting the positioning of the device, thereby ensuring the smooth uncoupling of the locomotive couplers and improving the uncoupling stability and reliability of the device.

[0046] like Figure 2 As shown, a universal joint 11 is provided between the hook lifting active rod 4 and the top of the electric push rod 6 .

[0047] Specifically, since a universal joint 11 is provided between the hook lifting active rod 4 and the top of the electric push rod 6, the electric push rod 6 can flexibly rotate through the universal joint 11 during the jacking process, thereby driving the hook lifting active rod 4 to rotate, preventing the electric push rod 6 from getting stuck or broken due to improper position, thereby ensuring the flexibility and stability of the locomotive hook automatic unhooking.

[0048] Furthermore, a push rod mounting seat 12 is provided at the bottom of the electric push rod 6 , one end of the push rod mounting seat 12 is provided on the locomotive end plate 1 , and the other end is connected to the electric push rod 6 via a pin shaft.

[0049] Specifically, since a push rod mounting seat 12 is provided at the bottom of the electric push rod 6, one end of the push rod mounting seat 12 is arranged on the locomotive end plate 1, and the other end is connected to the electric push rod 6 through a pin shaft, which can effectively prevent the electric push rod 6 from vibrating or displacing during the jacking process, ensuring the accuracy of the jacking position of the electric push rod 6 and the stability of the rotation process.

[0050] As Figure 2 shown, a rod cover 13 is provided at the top of the hook lifting active rod 4.

[0051] Specifically, by providing a rod cover 13 at the top of the hook lifting active rod 4, it can effectively prevent pollutants such as dust from entering the hook lifting active rod 4, avoid the hook lifting active rod 4 being stuck by pollutants, affect its rotation ability, achieve effective protection of the hook lifting active rod 4, and ensure that the hook lifting active rod 4 can maintain long-term stable operation ability.

[0052] According to an embodiment of the present invention, a monitoring camera is provided on the upper part of the coupler rod 3.

[0053] Specifically, by providing a monitoring camera on the upper part of the coupler rod 3, the operating states of the locomotive coupler and the device can be effectively monitored in real time, preventing the locomotive coupler from becoming loose due to the vibration of the locomotive during operation. At the same time, the posture of the device during the uncoupling process can be monitored, and the position of the coupler rod 3 can be adjusted as needed.

[0054] Furthermore, the device further includes a remote control button.

[0055] Specifically, since the device further includes a remote control button, and the control button is arranged on the locomotive or the operating platform in the locomotive cab, the device can perform the uncoupling operation on the locomotive coupler nearby on the locomotive or remotely on the operating platform in the locomotive cab, effectively improving the operation convenience and flexibility of the device.

[0056] The above content is only an example and explanation of the structure of the present invention.
