Description

Technical Field

[0001] This utility model relates to the technical field of train re-coupling equipment, specifically a train car coupler re-coupling device. Background Technology

[0002] In locations such as thermal power plants, smelters, cement plants, ports, and mines, bulk materials such as coal, coke, and ore are often transported by train. Bulk materials transported by train are generally unloaded using tippers. When the tipper is operating, it rotates the train's freight cars, causing the hooks of the freight cars to tilt to one side. If the hooks do not return to the center position and are not manually intervened, the hooks may fail to connect properly, leading to a slippage accident.

[0003] In existing technologies, during tippler operation, when the air conditioner pushes the empty car to the empty car line gate, the front and rear empty cars need to be aligned and the hook tongue opened during the hook-up operation to ensure a high success rate of hook connection. Currently, the most common re-hooking method is manual, where workers manually open the hook tongue and move the hook head. While manual re-hooking is acceptable for low-frequency, small-batch operations, it suffers from significant drawbacks such as low efficiency, high risk, and high cost in large-scale, high-paced tippler unloading scenarios like ports and power plants. Mechanical methods include swing arm structures and hydraulic linkage structures. One end of the swing arm is mounted on a three-axis moving base, and the hook head is mounted on the other end. The three-axis moving base is used to reposition the entire swing arm and hook head structure to move the hook head to the re-hooking position. However, existing re-hooking devices are often complex in structure and large in size, making them unsuitable for re-hooking operations in confined spaces. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1, please refer to Figure 1-4 This utility model provides a technical solution: a train car coupler re-coupling device. Since the worm gear reducer has a self-locking function, it facilitates maintaining the operation. The reducer 1 adopts a worm gear reducer. The motor 2 is a servo motor, fixed to the top surface of the reducer 1, and the power output shaft of the motor 2 is fixedly connected to the power input shaft of the reducer 1.

[0019] The fixing plate 3 is fixed to one side of the reducer 1; wherein, the fixing plate 3 is fixedly sleeved with a support shaft 3.3 whose inner end is fixedly connected to the bottom end of the reducer 1 near the bottom end.

[0020] The inner end of the drive shaft 4 is fixedly connected to the power output shaft of the reducer 1, and the middle part is rotatably sleeved with the fixed plate 3.

[0021] The bottom end of support arm 5 is fixedly sleeved to the outer end of transmission shaft 4; the bottom end of auxiliary support arm 6 is rotatably sleeved to the outer end of support shaft 3.3 and parallel to support arm 5; the top end of support arm 8 meshes with the top end of support arm 5. Among them, a sector gear 5.1 is fixed to the rear side of the top end of support arm 5, and a sector gear 8.1 that meshes with sector gear 5.1 is fixed to the front side wall of the top end of support arm 8.

[0022] The fixed base 7 has three connecting shafts 7.1 arranged in a triangular pattern. The fixed base 7 includes a pair of parallel plates, and the two ends of the connecting shafts 7.1 are fixedly sleeved to the plates. The top ends of the support arms 5 and 8 are rotatably mounted on the connecting shafts 7.1 on the upper sides of the fixed base 7, corresponding to the center of the sector gear. The top end of the auxiliary support arm 6 is rotatably mounted on the bottom connecting shaft 7.1. In addition, a connecting shaft 7.2 parallel to the connecting shafts 7.1 is mounted in the middle of the fixed base 7. A rectangular groove 8.2 is provided between the two side walls at the bottom end of the support arm 8.2, and a connecting shaft 8.4 perpendicular to the axis of the support arm 8.4 is provided in the middle of the rectangular groove 8.2.

[0023] The top of the small rocker arm 9 is rotatably connected to the connecting shaft 7.2; the top of the connecting rod 10 is rotatably connected to the bottom of the small rocker arm 9; the outer end of the hook head 11 is rotatably connected to the bottom of the connecting rod 10 and the inner side of the outer end is rotatably connected to the rectangular groove 8.2.

[0024] In summary, the motor 2 drives the transmission shaft 4 to rotate through the reducer 1, and the support arm 5 swings backward under the drive of the transmission shaft 4. The auxiliary support arm 6 swings with the support arm 5, and during the swing, the auxiliary support arm 6 remains parallel to the support arm 5, that is, the auxiliary support arm 6 plays the role of auxiliary support.

[0025] Due to the meshing of sector gear 5.1 and sector gear 8.1, support arm 8 will expand synchronously. During the expansion of support arm 8, small rocker arm 9 will swing accordingly. When the end of small rocker arm 9 makes an arc motion, it will pull on connecting rod 10. The pulling action of connecting rod 10 on the end of hook head 11 will cause hook head 11 to open synchronously and slowly.

[0026] During the re-coupling operation, the three-axis moving base provides the X-axis and Y-axis coordinate positions through a vision recognition system, and the Z-axis position is determined by a laser sensor. The multi-axis coordinated movement moves the hook head 11 to the position corresponding to the middle of the James coupler.

[0027] When motor 2 reverses, drive shaft 4 drives support arm 5 to swing forward, and support arm 8 retracts accordingly. Simultaneously, small rocker arm 9 pushes connecting rod 10, which in turn pushes the end of hook head 11, causing hook head 11 to retract as well. Hook head 11 then drags the Jan coupler tongue, displacing it and completing the train Jan coupler reset operation. Motor 2 then switches direction, allowing the swing arm assembly to extend further to ensure hook head 11 disengages from the train Jan coupler. Subsequently, in conjunction with the multi-axis movement of the three-axis moving base, hook head 11 is displaced from the Jan coupler position. Motor 2, through reducer 1, drives the support arm assembly to retract, returning all components to their initial positions.

[0028] Among them, the difference in circular height between the unfolded and retracted support arm 8 is small, making it suitable for working spaces with limited space and low ceilings. The hook head 11 is specially designed based on the angle and shape of the hook tongue when it is closed and opened, simulating the James hook head, to prevent slippage during re-hooking and ensure the success rate of re-hooking.

[0029] To ensure that the support arm 5 does not overshoot when it swings back to its original position, a retraction limit block 3.1 is fixed on the outer side of the fixed plate 3 at the front side of the support arm 5 near the bottom end.

[0030] To prevent excessive swinging when the support arm 2 8 is deployed, an deployment limit block 3.2 is fixed on the outer wall of the fixing plate 3 at the lower side of the bottom end of the auxiliary support arm 6.

[0031] In order to guide the connecting rod 10 so that it can move smoothly and steadily when pushed or pulled, positioning guide blocks 8.3 that are slidably sleeved with the connecting rod 10 are fixed on the outer side wall of the second support arm 8 near the top and bottom ends.

[0032] Example 2, please refer to Figure 1-5 Based on Embodiment 1, the connecting rod 10 is replaced with a combined rod with an elastic buffer mechanism in the middle.

[0033] The connecting rod 10 includes a rod 10.1 rotatably connected to the outer end of the hook head 11 at its bottom end, a rod 2 rotatably connected to the bottom end of the small rocker arm 9 at its top end, a connecting plate 10.3 fixed to the top end of rod 10.1 at its bottom center, a connecting plate 2 10.4 fixed to the bottom end of rod 2 10.2 at its top center, a connecting plate 3 10.5 slidably sleeved in the middle of rod 10.1, a pull rod 10.6 slidably sleeved at its top and bottom ends to connecting plate 2 10.4 and connecting plate 3 10.5 respectively and slidably sleeved in the middle to connecting plate 10.3, and a spring 10.7 fitted on the top and bottom of pull rod 10.6.

[0034] When the small rocker arm 9 pushes the connecting rod 10, it first pushes the second rod 10.2. The second rod 10.2 pushes the first connecting plate 10.3 downward through the elastic transmission of the second connecting plate 10.4 and the spring 10.7. The first connecting plate 10.3 then pushes the end of the hook head 11 through the first rod 10.1, causing the hook head 11 to retract.

[0035] When the small rocker arm 9 pulls the connecting rod 10, it first pulls the second rod 10.2. The second rod 10.2 pulls the pull rod 10.6 through the second connecting plate 10.4. The pull rod 10.6 pulls the third connecting plate 10.5. The third connecting plate 10.5 pushes the first connecting plate 10.3 in the opposite direction through the elastic transmission of the spring 10.7. This causes the first connecting plate 10.3 to pull the end of the hook head 11 through the first rod 10.1, causing the hook head 11 to unfold.

[0036] The above structure ensures that when the connecting rod 10 is pulled or pushed, the spring 10.7 provides a buffering effect to avoid excessive pushing or pulling that could cause structural damage.
