Description

Technical Field

[0001] The invention relates to the technical field of coupler coupling, and in particular to a coupler assembly and a rail vehicle. Background Art

[0002] The James coupler is mainly composed of a hook tongue, a locking pin and a body. When a coupling operation is required, the two carriages are placed on the same rail, and then the hook tongue of any of the coupled couplers needs to be opened. When one carriage approaches the other, the opened hook tongue hits and rotates into the bucket, and then the locking pin automatically falls, and the two carriages are connected.

[0003] However, when the rail vehicle is connected and hooked at a track curve or the centering effect of the body centering mechanism is poor, the two bodies are misaligned, causing the hook tongue to face the hook tongue, such as Figure 1 As shown, both hook tongues cannot rotate, and the vehicles are automatically marshaled. If the two vehicles are forced to approach each other, the couplers are likely to be damaged. At this time, the main body needs to be pushed manually so that the protruding parts of the two couplers to be connected are aligned with the concave parts of the other coupler, and then the connection operation can be completed. During the connection process, the space where people are located is narrow, and the moving vehicles may endanger the personal safety of the operators. During the automatic connection operation, if the two main bodies are not aligned, the automatic connection operation will fail, seriously affecting the execution of the automatic task. At the same time, the failure of the connection may also cause the vehicle to slip, causing an accident. Summary of the invention

[0004] In view of the shortcomings of the prior art described above, an object of the present invention is to provide a coupler assembly and a rail vehicle for solving the problems in the prior art where, when the rail vehicle is connected on a curve, the hook tongue may be against the hook tongue, resulting in the hook tongue being unable to rotate, and one of the bodies needs to be pushed manually. If the operating space is narrow, safety accidents or other vehicle accidents may occur.

[0009] A guide portion is installed on the second coupler, and the guide portion is used to cooperate with the guide cylinder to make the first coupler and / or the second coupler swing.

[0010] Furthermore, a first stop column is provided on the first hook tongue, and the guide cylinder is installed on the first stop column.

[0011] Further, the guide portion includes a first guide rail, which is installed at the second hook tongue relative to the guide cylinder, and the first guide rail includes a first section and a second section, the first section and the second section are smoothly connected, and the outer contour of the second section protrudes from the outer contour of the second hook tongue.

[0012] Furthermore, the guide portion further includes a second guide rail, which is installed on the second body toward the second hook tongue, and the profile of the second guide rail matches the second body.

[0013] Furthermore, the guide portion further includes a connecting column, and the first guide rail and the second guide rail are both connected to the second hook tongue via the connecting column.

[0014] Furthermore, the connecting column is trapezoidal, and the area of ​​the end of the trapezoidal connecting column away from the second coupler is smaller than the area of ​​the end close to the second coupler.

[0015] Furthermore, the connecting column is trapezoidal, and the area of ​​the end of the trapezoidal connecting column away from the second coupler is smaller than the area of ​​the end close to the second coupler.

The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0032] It should be noted that the diagram provided in the present embodiment only illustrates the basic concept of the present invention in a schematic manner, so the diagram only shows the components related to the present invention rather than drawing according to the number, shape and size of the components during actual implementation.

The structure, ratio, size, etc. illustrated in the drawings of the present specification are only used to match the content disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions that the present invention can implement, so they have no technical substantive significance. Any modification of the structure, change of the proportional relationship or adjustment of the size should still fall within the scope of the technical content disclosed by the present invention without affecting the effect that the present invention can produce and the purpose that can be achieved. At the same time, the terms such as "upper", "lower", "left", "right", "middle" and "one" quoted in this specification are only for the convenience of narration, and are not used to limit the scope of the present invention. The change or adjustment of its relative relationship should also be regarded as the scope of the present invention without substantially changing the technical content.

[0033] See also Figures 2 to 9 The present invention provides a coupler assembly, including a first coupler 1 and a second coupler 2, wherein the first coupler 1 and the second coupler 2 are respectively mounted on two carriages. The first coupler 1 has a first body 11 and a first coupler tongue 12 rotatably connected to the first body 11. The second coupler 2 has a second body 21 and a second coupler tongue 22 rotatably connected to the second body 21.

[0034] When the two couplers need to be connected, the two coupler bodies are close to each other. The first hook tongue 12 of the first coupler 1 is in an open state, and the second hook tongue 22 of the second coupler 2 can smoothly enter the first coupler 1. Subsequently, the first hook tongue 12 is restored to the closed position under the action of a corresponding mechanical device or by manual operation. At this time, the first hook tongue 12 and the second hook tongue 22 are engaged with each other. Fig. 9 shown.

[0035] A guide cylinder 3 is installed on the first coupler 1, and a guide portion 4 is installed on the second coupler 2. The guide portion 4 is used to cooperate with the guide cylinder 3 to allow the first coupler 1 and / or the second coupler 2 to swing.

[0036] Specifically, in this embodiment, the guide cylinder 3 is arranged above or below the first hook tongue 12 or both above and below the first hook tongue 12 , so that the guide cylinder 3 rotates with the rotation of the first hook tongue 12 .

[0037] When the first hook tongue 12 and the second hook tongue 22 collide, and under certain circumstances, the second hook tongue 22 cannot smoothly enter the first hook tongue 12, such as Figure 2As shown, at this time, the guide part 4 will play a key guiding role on the guide cylinder 3. In this process, the guide cylinder 3 will rotate relative to the guide part 4. As the guide cylinder 3 rotates, the main body of the first coupler 1 will be driven to swing. This swinging action can gradually align the first coupler 1 and the second coupler 2, thereby providing a strong guarantee for completing the automatic coupling operation. By forming a guiding structure with the guide cylinder 3 and the guide part 4, the coupler assembly can be connected more efficiently and accurately under various complex working conditions, thereby improving the reliability and automation of vehicle coupling. In addition, the guide cylinder 3 and the guide part 4 are located above or below the coupler, which will not interfere with the original coupler assembly, and there is no need to change the structure of the original coupler assembly.

[0038] The first retaining column 5 is provided on the first hook tongue 12, and the first retaining column 5 plays a key supporting and connecting role in the whole structure. There are many options for the connection between the first retaining column 5 and the first hook tongue 12. The first retaining column 5 can be made to penetrate the first hook tongue 12 from top to bottom, so that the combination of the two is tighter and more stable, ensuring that there will be no loosening or displacement under various working conditions. At this time, the first retaining column 5 can be expanded with the hole of the first hook tongue 12 by interference fit or connected by thread. At the same time, the first retaining column 5 can also be fixed to the first hook tongue 12 by bolt connection. The bolt connection has the advantages of easy installation and disassembly, which is convenient for operation when maintenance or replacement of parts is required. In addition, welding can also be selected. Welding can provide a very strong connection effect, so that the first retaining column 5 and the first hook tongue 12 become a whole, which can withstand large external forces.

[0039] A rotation pin 6 is provided between the first body 11 and the first hook tongue 12, and the rotation pin 6 is an important pivot for realizing the rotation of the first hook tongue 12 relative to the first body 11. Through the function of the rotation pin 6, the first hook tongue 12 can be flexibly rotated to meet different connection requirements.

[0040] In order to allow the guide cylinder 3 and the guide part 4 to play a better role when the first hook tongue 12 and the second hook tongue 22 collide, it is best to set the first stop column 5 at the end of the first hook tongue 12 away from the rotation pin 6. In this way, on the one hand, when the guide cylinder 3 is installed on the first stop column 5, it can play a guiding role in a larger range due to its position away from the rotation pin 6, so that the adjustment of the first hook tongue 12 and the second hook tongue 22 after the collision is more accurate and efficient. On the other hand, setting the first stop column 5 at this position can better balance the force distribution of the entire coupler assembly and improve the stability and reliability of the coupler.

[0041] At the same time, in order to further optimize the guiding effect, after the guide cylinder 3 is installed on the first stop column 5, the outer contour of the guide cylinder 3 must at least be flush with the outer contour of the first hook tongue 12. This ensures that when a collision occurs, the guide cylinder 3 can contact the guide portion 4 at the first time, thereby quickly starting the guiding effect. Alternatively, the outer contour of the guide cylinder 3 can also slightly exceed the outer contour of the first hook tongue 12, which can make the guide cylinder 3 contact the guide portion 4 in advance to a certain extent, improve the accuracy and stability of the guidance, and provide more reliable protection for the automatic coupling operation of the coupler.

[0042] like Figure 4 As shown, the guide portion 4 includes a first guide rail 41 , a second guide rail 42 and a connecting column 43 , and the first guide rail 41 , the second guide rail 42 are connected to the second coupler 2 via the connecting column 43 .

[0043] Specifically, the first guide rail 41 is arranged relative to the guide cylinder 3 and is installed on the second hook tongue 22. Due to such an installation position, the first guide rail 41 can rotate with the rotation of the second hook tongue 22. This synchronous rotation characteristic enables the first guide rail 41 to always maintain a corresponding positional relationship with the guide cylinder 3 during the connection process of the coupler, providing a basis for achieving an accurate guiding function.

[0044] The first guide rail 41 includes a first section 411 and a second section 412. The first section 411 is close to the inner side of the turn of the second hook tongue 22. The first section 411 and the second section 412 are smoothly connected, ensuring that there will be no abrupt transition during the guiding process, making the guiding function smoother. At the same time, the outer contour of the second section 412 slightly protrudes from the outer contour of the second hook tongue 22. When the first hook tongue 12 and the second hook tongue 22 collide and a guiding function is required, the protruding outer contour of the second section 412 can contact the guide cylinder 3 earlier, thereby quickly starting the guiding function. This protruding design can make the guide cylinder 3 contact the guide part 4 in advance, improve the accuracy and timeliness of the guidance, and provide a more powerful guarantee for the automatic coupling operation of the coupler.

[0045] The second guide rail 42 is installed at the second body 21 facing the second hook tongue 22, and the curved shape of the second guide rail 42 matches the shape of the second body 21 facing the second hook tongue 22. When the first coupler 1 and the second coupler 2 are in a normal connected state, the guide cylinder 3 can cooperate with the second guide rail 42. This matching relationship ensures the stability and reliability of the coupler after connection, providing a strong guarantee for the safe operation of the vehicle.

[0046] The length of the second guide rail 42 is designed to be slightly longer than the second body 21. In this way, the second guide rail 42 slightly longer than the second body 21 can provide an additional guide range during the coupling process, so that the guide cylinder 3 can be more accurately docked with the second guide rail 42, thereby improving the success rate and accuracy of the coupling.

[0047] The connection between the connecting column 43 and the second coupler 2 can be bolted or welded. Since the guide cylinder 3 is a cylindrical structure, in order to prevent the rotation of the guide cylinder 3 from interfering with the first hook tongue 12, the guide cylinder 3 is installed through the first stop column 5. In order to match the first guide rail 41 and the second guide rail 42 with the guide cylinder 3, a connecting column 43 is set between the first guide rail 41, the second guide rail 42 and the second coupler 2. The connecting column 43 allows a certain distance between the first guide rail 41, the second guide rail 42 and the coupler.

[0048] In some embodiments, the connecting column 43 is connected to the second coupler 2 by welding, and after connection, the connecting column 43 preferably does not exceed the outline of the second coupler 2. The connecting column 43 is in the shape of a trapezoid, and the area of ​​the end of the trapezoidal connecting column 43 away from the second coupler 2 is smaller than the area of ​​the end close to the second coupler 2. When the guide cylinder 3 contacts the first guide rail 41 or the second guide rail 42, the force acts on the first guide rail 41 or the second guide rail 42, and then is transmitted to the connecting column 43, and finally is transmitted to the second coupler 2. When the force is constant, the shorter the force arm of the connecting column 43 close to the first guide rail 41 or the second guide rail 42, the smaller the bending moment, so the cross-sectional area can be smaller, and the longer the force arm of the connecting column 43 close to the second hook tongue 22 from the first guide rail 41, the greater the bending moment, so the cross-sectional area should be designed to be larger. Of course, the entire connecting column 43 can also be designed to be conical or rectangular. In this embodiment, the connecting column 43 is designed to be trapezoidal, which can save materials.

[0049] The contact portion 44 and the connecting portion 45 are arranged vertically. Figure 5 As shown. The contact portion 44 directly contacts the guide cylinder 3 and plays a guiding role in the connection process of the coupler. When the first coupler 1 and the second coupler 2 are connected, the guide cylinder 3 interacts with the contact portion 44. The surface of the contact portion 44 is treated to ensure that it has sufficient smoothness and wear resistance, which can reduce friction when contacting with the guide cylinder 3 and achieve smooth guidance.

[0050] The connecting portion 45 is arranged on the side of the contact portion 44 away from the guide cylinder 3. Specifically, the connecting portion 45 is located in the middle of the contact portion 44. After the contact portion 44 and the connecting portion 45 are connected, they are in a T-shape. This layout helps to achieve uniform force transmission and structural stability. The main function of the connecting portion 45 is to connect with the connecting column 43. The connecting column 43 is connected with the connecting portion 45 to firmly fix the first guide rail 41 and the second guide rail 42 on the second coupler 2. The connecting portion 45 is connected to the connecting column 43 by welding to ensure the reliability and stability of the connection, and can withstand various forces generated during the operation of the coupler.

[0051] The connection column 43 is connected to the connection portion 45 . Specifically, one side of the trapezoidal connection column 43 is located at the junction of the contact portion 44 and the connection portion 45 , so that one side of the connection column 43 provides certain support to the contact portion 44 through the rear portion thereof.

[0052] A rotating pin 6 is arranged between the first body 11 and the first hook tongue 12, a second stop column 7 is arranged on the first body 11, an elastic member 8 is sleeved on the rotating pin 6, one end of the elastic member 8 is connected to the second stop column, and the other end is connected to the first stop column 5; a connecting plate 9 is connected between the rotating pin 6 and the first stop column 5. The elastic member 8 can be a coil spring or a torsion spring.

[0053] When the locking pin of the first coupler 1 is opened, the first coupler tongue 12 can automatically rotate relative to the first body 11 under the action of the elastic member 8 to reach the maximum open state.

[0054] On the other hand, the present application also provides a rail vehicle, comprising the above-mentioned coupler assembly.
