Description

Technical Field

[0001] The utility model relates to the technical field of coupler straightening, in particular to a coupler straightening robot. Background Art

[0002] Automatic couplers are widely used in the domestic railway system. Their working principle is that when the lever of a coupler is raised, the coupler automatically uncouples and hooks up, regardless of whether the locomotive pulls out a car or collides with another car. Gondola cars, commonly used to transport bulk cargo such as coal and iron ore, typically rely on a car tipper system for unloading. During unloading, the gondola car is first uncoupled from the train by uncoupling, then towed into the car tipper. The tipper rotates the car approximately 160 degrees to complete the unloading process, a highly automated and efficient process.

[0003] However, during the process of the car tipper rotating to unload the car, the coupler body will tilt to one side of the discharge port due to the effect of gravity and will not be able to return to its original position automatically. This tilted state of the coupler body may cause abnormalities in the shunting machine's pushing of the car and the subsequent collision hook, and may even cause an accident. Therefore, before being pushed out by the shunting machine, the coupler body that is tilted front and back of the car needs to be manually straightened. At present, the main method of manual straightening is to bend it manually or use a crowbar. This usually requires entering the two ends of the car tipper to operate without interrupting the automatic system of the car tipper, so there is a risk of people being drawn into the equipment during the whole process. In order to solve this problem, a device that can automatically straighten the coupler of the open car is needed. Summary of the Invention

[0040] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings to further illustrate the present invention.

[0041] First, combine Figures 1-3 A coupler straightening robot according to an embodiment of the present invention is described, which is used for straightening couplers and has a wide range of application scenarios.

[0042] like Figures 1-3As shown, a coupler straightening robot according to an embodiment of the present invention comprises a base plate 100 , a rotation module, a flip module, a telescopic column 400 , a transmission rod 500 , a driving module and a straightening plate 700 .

[0043] Specifically, if Figures 1-3 As shown, the rotating module is arranged at the top of one side of the base plate 100 to provide the driving force for the rotational motion. The rotating module includes: a housing 201, a rotating motor 202, a rotating shaft 203, and a transmission mechanism 204. The housing 201 is arranged at the top of one side of the base plate 100; the rotating motor 202 is arranged inside the housing 201; one end of the rotating shaft 203 is inserted into the interior of the housing 201, and the other end of the rotating shaft 203 passes through the housing 201 and extends to the outside to connect to the flip module; the transmission mechanism 204 connects the output end of the rotating motor 202 and the rotating shaft 203, and is used to transmit the power of the rotating motor 202 to the rotating shaft 203 to control the rotation of the rotating shaft 203. By controlling the movement of the rotating motor 202, the transmission mechanism 204 can transmit power to the rotating shaft 203, driving the rotating shaft 203 to rotate, thereby causing the flip module to rotate horizontally.

[0044] Further, if Figure 3 As shown, in this embodiment, the transmission mechanism 204 is a gear transmission mechanism 204, and a belt transmission mechanism 204 or other existing transmission mechanisms 204 that can transmit power may also be used.

[0045] Specifically, if Figures 1-3 As shown, the flip module is located at the output end of the rotation module and rotates under the influence of the rotation module. The flip module includes a flip plate 301, a pair of flip frames 302, a flipper 303, and a flip shaft 304. The flip plate 301 is connected to the output end of the rotation module; the pair of flip frames 302 are located on the flip plate 301; the flipper 303 is located on the flip plate 301 and provides the driving force for flipping. The flip shaft 304 is rotatably mounted on the pair of flip frames 302 at both ends. The flip shaft 304 is connected to the telescopic column 400, and one end of the flip shaft 304 is connected to the output end of the flipper 303. By controlling the movement of the flipper 303, the flip shaft 304 can be rotated, thereby driving the telescopic column 400 to flip.

[0046] Further, if Figures 1-3 As shown, the flipper 303 is a combination of a motor and a reducer.

[0047] Specifically, if Figures 1-3 As shown, the telescopic column 400 is arranged at the output end of the flip module and performs flipping motion under the action of the flip module.

[0048] Specifically, if Figures 1-3As shown, one end of the transmission rod 500 is inserted into the telescopic column 400, and the other end of the transmission rod 500 passes through the telescopic column 400 and extends to the outside.

[0049] Specifically, if Figures 1-3 As shown, the drive module connects the telescopic column 400 and the transmission rod 500, driving the transmission rod 500 to perform guided telescopic motion within the telescopic column 400. The drive module includes a frameless motor, a transmission nut 602, a transmission block 603, a first bearing 604, and a second bearing 605. The stator 6011 of the frameless motor is connected to the inner wall of the telescopic column 400; the transmission nut 602 is disposed within the telescopic column 400 and connected to the rotor 6012 of the frameless motor; the transmission block 603 is disposed within the transmission nut 602 and threadedly connected to the transmission nut 602. The transmission block 603 is connected to one end of the transmission rod 500; the first bearing 604 is disposed between the rear end of the transmission nut 602 and the inner wall of the telescopic column 400; and the second bearing 605 is disposed between the front end of the transmission nut 602 and the inner wall of the telescopic column 400. By controlling the movement of the frameless motor, the stator 6011 of the frameless motor drives the rotor 6012 to rotate, thereby rotating the transmission nut 602, so that the transmission block 603 reciprocates along the axial direction in the transmission nut 602 and drives the transmission rod 500 to reciprocate.

[0050] Further, if Figures 1-3 As shown, the driving module further includes: an encoder 606 , which is connected to the transmission nut 602 and is used to detect the rotation parameters of the transmission nut 602 .

[0051] Further, if Figures 1-3 As shown, the driving module further includes: a guide sleeve 607 , which is disposed between the inner wall of the telescopic column 400 and the transmission rod 500 , and is used to guide the movement of the transmission rod 500 .

[0052] Specifically, the centralizing plate 700 is connected to the other end of the transmission rod 500. A protective cover is provided on the surface of the centralizing plate 700 to prevent the centralizing plate 700 from contacting and wearing the coupler.

[0053] Furthermore, a coupler straightening robot according to an embodiment of the present invention also includes: a support frame 800, which is arranged on the top of the other side of the base plate 100, and an arc-shaped support groove 801 is provided on the top of the support frame 800, which is used to store and support the telescopic column 400 when the robot is not in use.

[0054] Working principle: The straightening robot is connected to an external moving mechanism, and the device is moved parallel to the open car through the external moving mechanism. When the external moving mechanism moves the device to the straightening position, the flipping module drives the telescopic column 400 to flip from a horizontal state to a vertical state, and then the rotation module drives the flipping module and the telescopic column 400 to rotate 90°, so that the telescopic column 400 faces the coupler. The flipping module drives the telescopic column 400 to flip from a vertical state to a horizontal state. At this time, the straightening plate 700 is facing the coupler, and the drive module drives the transmission rod 500 to extend and retract outward in the telescopic column 400, thereby driving the straightening plate 700 to move toward the coupler and contact the coupler to straighten the coupler. After the coupler is straightened, each component is reset, and the telescopic column 400 is stored in the arc-shaped support groove 801 at the top of the support frame 800.

[0055] Above, refer to Figures 1-3 This utility model describes a coupler-righting robot. Firstly, it can completely replace manual operation, automatically and accurately completing the task of righting a coupler. This feature not only significantly improves work efficiency but also fundamentally ensures operational safety, eliminating the dangers and risks of accidents that can occur during manual righting.

[0056] Secondly, the coupler straightening robot automatically folds away when not in use. Its compact and rational design minimizes space usage, making storage and transportation more convenient, effectively saving valuable space and expanding the possibilities for the layout and use of other equipment.
