Description

Technical Field

[0001] This utility model relates to the field of maintenance platform technology, specifically a maintenance platform for EMU brake discs. Background Technology

[0002] The brake disc is an important component of the braking system of a high-speed train. During braking, the brake pads clamp the friction surface of the brake disc to achieve train braking. (See appendix) Figure 1 As shown, the brake disc is a disc structure, which mainly includes a hub and a friction disc. The friction disc and the hub are fixedly connected by nine bolts. Currently, after the train enters the maintenance period, the brake disc needs to be removed from the wheelset for maintenance. After removal, the brake disc changes from a vertical position to a horizontal position for cleaning, grinding and other maintenance operations. To facilitate maintenance, a high-speed train brake disc maintenance platform is needed.

[0003] The EMU brake disc maintenance platform disclosed in CN221696845U, although it is equipped with a sliding displacement component, so that the bearing platform can be vertical relative to the horizontal plane after passing through the maintenance slot, avoiding frequent flipping of the brake disc during maintenance, effectively reducing labor intensity and facilitating maintenance, and the notch can expose the side surface of the brake disc to the maximum extent, further improving the convenience of cleaning and polishing.

[0004] However, the maintenance platform for the train's brake discs has the following drawbacks: (1) The brake disc maintenance platform of this EMU has weak operation safety function. When grinding, the generated debris can easily scratch the skin of personnel. The debris adheres to the surface of gloves and tools, causing mechanical wear of tools and reducing their service life. (2) The brake disc maintenance platform of this EMU has a weak function in maintaining the stability of the brake disc. Since the device only uses fixing parts to stabilize the position of the brake disc after the brake disc is placed, if the fixing parts are loose when the bearing platform is flipped, the brake disc has a certain risk of slipping off, causing the brake disc to fall off and be damaged. Utility Model Content

[0005] The purpose of this utility model is to provide a maintenance platform for the brake discs of high-speed trains to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-speed train brake disc maintenance platform, comprising: a base, a cleaning component, and a limiting component. The top of the base is provided with a rectangular slot, the inner sidewall of the rectangular slot is provided with a connecting frame, the inner sidewall of the connecting frame is fixedly connected with a filter screen, the bottom wall of the rectangular slot is provided with an exhaust fan, one side of the inner wall of the rectangular slot is fixedly connected with a baffle, the bottom side of the baffle is fixedly connected with a fixing frame, and the inner sidewall of the fixing frame is slidably connected with a collection frame. A rectangular frame is fixedly connected to the top of the base. A limiting rod is fixedly connected to the inner side wall of the rectangular frame. A limiting slider is slidably connected to the outer surface of the limiting rod. A placement frame is rotatably connected to the top of the limiting slider. A limiting frame is rotatably connected to the top side of the placement frame. A limiting block is fixedly connected to the bottom side of the limiting frame. A limiting slot is opened on the top side of the placement frame near the limiting block. A clamping screw is threaded into the interior of the placement frame. A clamping plate is fixedly connected to one end of the clamping screw.

[0007] Optionally, the inner bottom wall of the rectangular slot is provided with a connecting groove, and the bottom of the fixing frame is connected to the base through the connecting groove, which connects and fixes the fixing frame and the base.

[0008] Optionally, a servo motor is fixedly connected to one side of the top of the base, a rotating rod is fixedly connected to the output end of the servo motor, and an adjustment plate is fixedly connected to the outer surface of the rotating rod. The servo motor is model FT--AB. When the device is powered by an external power source, the servo motor is started to drive the rotating rod to rotate. The rotation of the rotating rod drives the adjustment plate to rotate, and at the same time, the adjustment plate limits the position of the placement frame.

[0009] Optionally, a fixing rod is fixedly connected to the side of the placement frame. The outer surface of the fixing rod is rotatably connected to the inside of the adjustment plate. When the adjustment plate rotates, the fixing rod limits the position of the adjustment plate and, in conjunction with the fixing rod, limits the position of the placement frame.

[0010] Optionally, the number of clamping screws is two, and the number of clamping plates is two. The arrangement of two clamping screws and two clamping plates can further improve the stability of the brake disc after placement.

[0011] Optionally, a semi-circular groove is provided on the side of the rectangular slot, which facilitates the removal of the connecting frame from the rectangular slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. The EMU brake disc maintenance platform, through the setting of the cleaning components, creates negative pressure inside the rectangular slot when the exhaust fan is turned on, thereby sucking up the debris generated during maintenance and grinding. At the same time, the filter screen filters out larger solids, and the baffle blocks the debris from falling into the exhaust fan. The debris slides down from one side of the baffle into the collection box. After a certain amount is collected, the collection box is removed and then reattached to the inner wall of the fixed frame for collection again. This achieves the effect of improving operational safety and avoiding the situation where debris generated during grinding operations can easily scratch the skin of personnel, and debris adhering to the surface of gloves and tools, causing mechanical wear and reducing the service life of tools.

[0013] 2. This EMU brake disc maintenance platform, through the setting of the limiting component, allows for the following operation: The brake disc is placed on the inner wall of the placement frame, and then the clamping screw is rotated to move the clamping plate, which clamps the bottom of the brake disc, maintaining its stability. The limiting frame is then rotated until the limiting block engages in the limiting slot, thus limiting the position of the upper surface of the brake disc and preventing it from falling off. This further maintains the stability of the brake disc and avoids the situation where, after the brake disc is placed, only the fixing component stabilizes its position. If the fixing component loosens during the rotation of the platform, the brake disc may slip and fall, potentially causing damage. Attached Figure Description

[0016] 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.

[0017] Please see Figures 1-4 As shown, this utility model provides a technical solution: a high-speed train brake disc maintenance platform, comprising: a base 1, a cleaning component 2, and a limiting component 3. A rectangular slot 201 is formed at the top of the base 1. A connecting frame 202 is provided on the inner side wall of the rectangular slot 201. A filter screen 203 is fixedly connected to the inner side wall of the connecting frame 202. A fan 204 is provided on the inner bottom wall of the rectangular slot 201. A baffle 205 is fixedly connected to one side of the inner wall of the rectangular slot 201. A fixing frame 206 is fixedly connected to the bottom side of the baffle 205. The inner side of the fixing frame 206... A collection frame 207 is slidably connected to the side wall. When the exhaust fan 204 is turned on, a negative pressure is created inside the rectangular slot 201, which in turn sucks up the debris generated during maintenance and grinding. At the same time, the filter screen 203 filters out larger solids, and the baffle 205 blocks the debris to prevent it from falling into the exhaust fan 204. The debris slides down from one side of the baffle 205 into the collection frame 207. After a certain amount is collected, the collection frame 207 is removed, and then it can be reattached to the inner wall of the fixed frame 206 for collection again. The surface of the baffle 205 is mesh-like, and the filter screen 203 is made of 304 stainless steel (corrosion resistant, high strength, and adaptable to the impact of metal debris in the maintenance environment). The baffle 205 has an inclination angle of 35°-45° (to guide debris to slide down the plate surface into the collection frame and avoid accumulation), and the mesh aperture is 8-10mm (allowing airflow while blocking medium-sized particles that have not been filtered by the filter screen). A rectangular frame 301 is fixedly connected to the top of the base 1. A limiting rod 302 is fixedly connected to the inner side wall of the rectangular frame 301. A limiting slider 303 is slidably connected to the outer surface of the limiting rod 302. A placement frame 304 is rotatably connected to the top of the limiting slider 303. A limiting frame 305 is rotatably connected to one side of the top of the placement frame 304. A limiting block 306 is fixedly connected to one side of the bottom of the limiting frame 305. A limiting slot 307 is provided on the top side of the placement frame 304 near the limiting block 306. The internal thread of the placement frame 304 is connected to a clamping screw 308. One end of the clamping screw 308 is fixedly connected to a clamping plate 309. The brake disc is placed on the inner wall of the placement frame 304. Then, the clamping screw 308 is rotated to move the clamping plate 309, so that the clamping plate 309 clamps the bottom of the brake disc and maintains the stability of the brake disc placement. Then, the limiting frame 305 is rotated until the limiting block 306 is engaged in the limiting slot 307, so that the limiting frame 305 limits the position of the upper surface of the brake disc and prevents the brake disc from falling off. A connecting groove is provided on the inner bottom wall of the rectangular slot 201. The bottom of the fixing frame 206 is connected to the base 1 through the connecting groove, and the connecting groove connects and fixes the fixing frame 206 and the base 1. A servo motor 4 is fixedly connected to one side of the top of the base 1. A rotating rod 5 is fixedly connected to the output end of the servo motor 4. An adjustment plate 6 is fixedly connected to the outer surface of the rotating rod 5. The model of the servo motor 4 is 1FT7-1000-1AB0. When the device is powered by an external power source, the servo motor 4 is started and drives the rotating rod 5 to rotate. The rotation of the rotating rod 5 drives the adjustment plate 6 to rotate. At the same time, the adjustment plate 6 limits the position of the placement frame 304. The servo motor 4 is controlled by a PLC controller (model S7-1200) to achieve pulse control. A fixing rod 7 is fixedly connected to the side of the placement frame 304. The outer surface of the fixing rod 7 is rotatably connected to the inside of the adjustment plate 6. When the adjustment plate 6 rotates, the fixing rod 7 limits the position of the adjustment plate 6 and, in conjunction with it, limits the position of the placement frame 304. There are two clamping screws 308 and two clamping plates 309. The arrangement of two clamping screws 308 and two clamping plates 309 can further improve the stability of the brake disc after placement. A semi-circular groove 8 is provided on the side of the rectangular slot 201, which facilitates the removal of the connecting frame 202 from the rectangular slot 201.

[0018] In this invention, the working steps of the device are as follows: First step: Turn on the exhaust fan 204 to create negative pressure inside the rectangular slot 201, thereby sucking up the debris generated during maintenance and grinding. At the same time, the filter screen 203 filters out larger solids, and the baffle 205 blocks the debris to prevent it from falling into the exhaust fan 204. The debris slides down from one side of the baffle 205 into the collection frame 207. After a certain amount is collected, remove the collection frame 207, and then reattach the collection frame 207 to the inner wall of the fixed frame 206 to collect again.

[0019] The second step is to place the brake disc on the inner wall of the placement frame 304, then rotate the clamping screw 308 to move the clamping plate 309 so that the clamping plate 309 clamps the bottom of the brake disc and maintains the stability of the brake disc placement. Then rotate the limiting frame 305 until the limiting block 306 is engaged in the limiting slot 307 so that the limiting frame 305 limits the position of the upper surface of the brake disc and prevents the brake disc from falling off.

[0020] The third step: The connecting groove connects and fixes the fixed frame 206 to the base 1. The servo motor 4 is model 1FT7-1000-1AB0. When the device is powered by an external power source, the servo motor 4 is started and drives the rotating rod 5 to rotate. The rotating rod 5 drives the adjusting plate 6 to rotate. At the same time, the adjusting plate 6 limits the position of the placement frame 304. When the adjusting plate 6 rotates, the fixed rod 7 limits the position of the adjusting plate 6. At the same time, the position of the placement frame 304 is limited by the cooperation. The two clamping screws 308 and the two clamping plates 309 can further improve the stability of the brake disc after placement. The semi-circular groove 8 makes it easy to remove the connecting frame 202 from the rectangular slot 201.
