Abstract
Description
Technical Field
[0001] This utility model belongs to the field of rail vehicle technology, and in particular relates to a swing block type suspension device and a coupler. Background Technology
[0002] The coupler suspension device in the coupler buffer system is used to provide stable support for the coupler and to provide restoring force to the coupler when it swings up and down or left and right.
[0003] During train operation, due to the complexity of the operating environment, the coupler not only needs a certain range of motion in the lateral direction to adapt to track irregularities and vehicle swerving, but also needs appropriate elasticity or variability in the longitudinal direction to buffer longitudinal impacts during train operation. However, existing coupler suspension devices mostly adopt a relatively fixed structural design with a relatively simple motion mechanism, which makes it difficult to meet the dynamic changes in the spatial position of the coupler under different operating environments. At the same time, it also limits the lateral swing range of the coupler, which may result in large lateral forces between the coupler and the coupler of adjacent vehicles, aggravating wear on the coupler and vehicle connection parts, and potentially causing serious safety accidents such as derailment in extreme cases.

[0055] The technical solution of this utility model will be described in detail below with reference to specific embodiments and the accompanying drawings.
[0056] As attached Figure 1 - Appendix Figure 13 As shown in an illustrative embodiment of the swing block type suspension device of this utility model, the suspension device is disposed at the hook head of the hook 5 to provide an upward support force for the hook 5 and to provide a centering force for the hook 5 when the hook 5 swings left and right. The suspension device includes a swing block assembly 1 and a pair of swing block hangers 2.
[0057] Among them, as attached Figure 4 - Appendix Figure 6 As shown, the swing block assembly 1 is located below the coupler 5 and includes a swing block body 11, a swing block pad 12, an elastic element 13, and a guide element 14.
[0058] In the sway block component 1, as shown in the attached Figure 7 As shown, the main body 11 of the swing block has a U-shaped structure, and a cavity 111 with an opening at the top is provided in the middle recess for installing the elastic element 13 and the guide element 14.
[0059] The swing block pad 12 is disposed above the opening of the receiving cavity 111, and its two ends are slidably connected to the swing block body 11, so that the swing block pad 12 can slide vertically within a certain range. The top end face of the swing block pad 12 is in contact with the bottom of the coupler 5 to provide vertical support for the coupler 5.
[0060] One end of the guide member 14 is fixedly connected to the swing block pad 12, and the other end passes through the receiving cavity 111 and protrudes through the bottom of the swing block body 11. It is used to guide the swing block pad 12 so that the swing block pad 12 can move vertically above the receiving cavity 111. The protruding end of the guide member 14 is provided with a first limiting member 141 to prevent the guide member 14 from coming out of the swing block body 11. In this embodiment, the first limiting member 141 is a fastening nut. The outer wall of the guide member 14 is provided with a threaded section that is connected to the fastening nut. After the hanging device is connected to the hook 5, the support height of the entire swing block assembly 1 on the hook 5 can be adjusted by adjusting the position of the fastening nut on the guide member 14.
[0061] The elastic element 13 is disposed within the receiving cavity 111, with its two ends respectively contacting and connecting to the swing block pad 12 and the swing block body 11. It has a vertical elastic travel to meet the needs of the hook body moving downwards when the coupler 5 rotates vertically and the swing block swinging upwards horizontally. Simultaneously, it provides elastic support for the swing block pad 12. When the swing block pad 12 is subjected to an external force and slides vertically, the elastic element 13 deforms and stores elastic potential energy. After the external force disappears, the elastic element 13 resets, causing the swing block pad 12 to return to its initial position, thus achieving the restoration function and causing the coupler 5 to return to its initial position. In this embodiment, the elastic element 13 is specifically a spring.
[0062] A pair of swing block hangers 2 are respectively set on both sides of the coupler 5. One end is connected to the impact seat 3 fixed to the car body, and the other end is connected to the swing block body 11. They play the role of hoisting and fixing the swing block assembly 1, so that the entire swing block type hanging device can be stably installed on the coupler 5, effectively reducing the impact during the operation of the vehicle and ensuring the smoothness of the train operation.
[0063] In the above illustrative embodiment, the swing block body 11, swing block pad 12, elastic element 13, and guide element 14 in the swing block assembly 1 cooperate with each other, allowing the swing block pad 12 to slide on the swing block body 11 and to reset under the action of the elastic element 13 after being subjected to force. This satisfies the needs of the hook body moving downward when the coupler 5 rotates vertically and the rising height when swinging horizontally, thus realizing the restoration of the coupler 5 after being subjected to force. The connection state between the coupler 5 and the suspension device in the up-and-down and left-and-right swinging states of the coupler 5 is shown in the attached figure. Figure 12 - Appendix Figure 17 As shown.
[0064] In some embodiments of this utility model, as shown in the appendix Figure 4 - Appendix Figure 6As shown, a slot is provided at the lower part of the hook body of the coupler 5. A second limiting member 15 is provided on the top end face of the swing block pad 12, and the second limiting member 15 is connected to the slot. The second limiting member 15 is specifically a pin. The swing block type suspension device forms a tighter and more stable connection with the coupler 5 through the cooperation of the pin and the slot. During the left and right swinging of the coupler 5, the pin at the upper part of the swing block pad 12 cooperates with the slot at the lower part of the hook body, driving the swing block assembly 1 to swing.
[0065] In some embodiments of this utility model, as shown in the appendix Figure 7 As shown, the swing block body 11 has a vertically extending guide groove 112, and the swing block pad 12 has guide portions 121 at both ends along its length. The guide portions 121 are inserted into the guide groove 112 and cooperate with the swing block body 11 to achieve a sliding connection between the swing block pad 12 and the swing block body 11. The cooperation between the guide groove 112 and the guide portions 121 provides a precise guiding path for the sliding of the swing block pad 12, ensuring the stability and straightness of the swing block pad 12 during the sliding process, and ensuring that the elastic element 13 can more effectively perform its restorative function.
[0066] In some embodiments of this utility model, as shown in the appendix Figure 4 and attached Figure 7 As shown, the pendulum block body 11 is provided with a limiting part 113 protruding from the pendulum block body 11, as shown in the attached figure. Figure 9 - Appendix Figure 10 As shown, a limiting plate 4 is provided below the limiting part 113. The limiting plate 4 is fixedly connected to the coupler 5 and cooperates with the limiting part 113 to limit the swing block body 11 when it moves downward under the action of the coupler 5.
[0067] In some embodiments of this utility model, the limiting part 113 is configured in a downward hook shape, and the connection between the limiting support plate 4 and the swing block body 11 is configured in an upward hook shape. The limiting part 113 and the limiting support plate 4 are hooked together. This hooking structure enhances the reliability of the connection between the limiting part 113 and the second limiting member 15, and prevents the limiting part 113 and the second limiting member 15 from separating when the car coupler 5 is subjected to strong impact or vibration. This also prevents the swing block body from moving back and forth significantly when the car coupler 5 moves back and forth, causing the swing block crane to separate from the swing block body.
[0068] In some embodiments of this utility model, the elastic element 13 is sleeved on the outside of the guide element 14. The guide element 14 provides certain support and protection for the elastic element 13, preventing the elastic element 13 from twisting, tilting or deviating from its normal working position during operation, ensuring that the elastic element 13 can be evenly stressed and stably perform its elastic recovery function.
[0069] In some embodiments of this utility model, at least one side of the bottom of the accommodating cavity 111 and the bottom of the swing block pad 12 is provided with a protrusion 16, the end of the elastic member 13 is sleeved with the protrusion 16, and the protrusion 16 limits the elastic member 13.
[0070] In a specific embodiment of this utility model, as shown in the appendix Figure 6 As shown, there are two guide members 14, which are symmetrically arranged in the accommodating cavity 111; there are three elastic members 13, which are arranged in the accommodating cavity 111, and the elastic members 13 on both sides are respectively sleeved on the outside of the two guide members 14, and the two ends of the middle elastic member 13 are limited by the protrusions 16.
[0071] In some embodiments of this utility model, the pendulum block body 11 is provided with a connecting part 114, which is a hook-claw structure, and the pendulum block body 11 is connected to the pendulum block hanger 2 through the connecting part 114.
[0072] In some embodiments of this utility model, the bottom of the swing block pad 12 has a connecting hole 122, the guide is inserted into the connecting hole 122 at the bottom of the swing block pad 12, and is fixedly connected to the swing block pad 12 by a connector that radially penetrates the guide and is inserted into the swing block pad 12.
[0073] In some embodiments of this utility model, the top of the swing block pad 12 has a connecting hole 122, the second limiting member 15 is inserted into the connecting hole 122 at the top of the swing block pad 12, and is fixedly connected to the swing block pad 12 by a connecting member that radially penetrates the second limiting member 15 and is inserted into the swing block pad 12.
[0074] In some embodiments of this invention, a non-metallic wear plate is provided above the swing block pad 12 to reduce wear on the hook body 5. The top end face of the wear plate is in contact with the hook body 5.
[0075] Some embodiments of this utility model further provide a vehicle coupler 5, including a vehicle coupler 5 body and a swing block type suspension device; the swing block type suspension device is the aforementioned swing block type suspension device, the vehicle coupler 5 body is mounted on the swing block type suspension device, and can move up and down and swing left and right.
