Description

Technical Field

[0001] This application relates to the technical field of rail wheel grinding equipment, and in particular to a debris cleaning device for rail wheel grinding. Background Technology

[0002] During the production and processing of rail wheels, a grinding lathe is needed to grind the curved surface and sides of the rail wheels so that the contact surface between the rail wheels and the rails remains in close contact during subsequent operation. Existing rail wheel grinding lathes include a lathe with a fixed multi-jaw chuck. During use, the rail wheel is clamped in the multi-jaw chuck, which drives the rail wheel to rotate. Two grinding mechanisms on the lathe grind the side and arc surfaces of the rail wheel respectively. To reduce dust emission and avoid overheating during grinding, some grinding lathes are equipped with atomizing nozzles. The atomizing nozzles are connected to the output end of a liquid pump via pipes, and the input end of the liquid pump is connected to a storage tank containing grinding fluid via pipes. During grinding, the atomizing nozzles spray grinding fluid onto the grinding surface. The mixture of debris and grinding fluid falls onto a filter screen on the lathe under gravity. After passing through the filter screen, the liquid is stored in a wastewater tank. The debris is carried to a collection box by a scraper that moves back and forth via a telescopic mechanism on the lathe.

[0003] However, during the use of traditional rail wheel grinding lathes, the grinding fluid sprayed onto the rail wheel mixes with the debris and is driven to rotate by the rail wheel. Under the action of centrifugal force, the debris is easily thrown out of the lathe, resulting in a decrease in the cleaning effect of the debris and difficulty in collecting the thrown grinding fluid and debris. In addition, the filter screen is easily clogged by fine debris. As the usage time increases, it is difficult for the grinding fluid to be effectively separated from the debris on the filter screen, resulting in a decrease in the debris cleaning effect. Summary of the Invention

[0004] This application proposes a debris cleaning device for grinding rail wheels, which has the advantages of avoiding filter clogging and improving cleaning effect, and solves the problem that the grinding fluid and debris mixture is easily thrown away and the separation effect is poor.

[0005] To achieve the above objectives, this application adopts the following technical solution: a debris cleaning device for grinding rail wheels, comprising a support base, a fixed seat fixedly disposed on one side of the top of the support base, a movable seat slidably disposed on one side of the top of the support base, the support base, the fixed seat and the movable seat forming a grinding lathe, a separation box fixedly disposed on one side inside the support base, a liquid storage tank fixedly connected to the middle position inside the separation box, a first filter plate for separating grinding fluid and debris disposed on the top of the liquid storage tank, a collection box for storing debris fixedly disposed on the bottom of the support base, and a telescopic mechanism for driving the movable seat to move fixedly disposed on one side of the top of the support base;

[0006] A shield is fixedly connected to one side of the movable seat. The top of the shield is arc-shaped. An exhaust pipe is provided on the grinding lathe. The shield can fit snugly with the fixed seat to form a closed cavity with the bearing seat, fixed seat, and movable seat. The exhaust pipe can discharge airflow to clean the closed cavity, and the direction of the airflow acting on the first filter plate is opposite to the filtration direction of the first filter plate.

[0007] The beneficial effects of this invention are as follows:

[0008] This application provides a debris cleaning device for grinding rail wheels. A telescopic mechanism drives a movable seat to move, forming a closed cavity between the movable seat, shield, fixed seat, and bearing seat. This restricts the splashing of debris and grinding fluid, and prevents the mixture of grinding fluid and debris from being centrifugally ejected from the lathe by the rotating rail wheel. Combined with an exhaust pipe, an airflow is formed to clean the closed cavity, ensuring effective cleaning of debris and grinding fluid. Furthermore, the airflow acts in the opposite direction on the first filter plate, blowing open the filter holes blocked by debris, thus improving the collection and cleaning effect of debris while preventing clogging of the first filter plate.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1, as Figures 1-4 and Figure 6 A debris removal device for grinding rail wheels includes a support base 1, a fixed base 2 fixedly mounted on one side of the top of the support base 1, and a movable base 3 slidably mounted on the other side of the top of the support base 1. The support base 1, the fixed base 2, and the movable base 3 constitute a grinding lathe. A guide rail is fixedly mounted on the top of the support base 1. The number of guide rails is set to two, and the two guide rails are symmetrically arranged about the center line of the movable base 3. The movable base 3 is slidably sleeved on the outside of the guide rails. A multi-jaw chuck for clamping rail wheels 4 and driving rail wheels 4 to rotate is provided on one side of the fixed base 2. A first grinding mechanism 7 is fixedly mounted on one side of the movable base 3. The first grinding mechanism 7 is used to grind the arc surface of the rail wheel 4. A second grinding mechanism 23 is fixedly mounted on one side of the movable base 3. The second grinding mechanism 23 is used to grind the side of the rail wheel 4.

[0020] Two atomizing nozzles 15 are provided on one side of the fixed base 2. The positions of the two atomizing nozzles 15 correspond to the positions of the first grinding mechanism 7 and the second grinding mechanism 23, respectively. The atomizing nozzles 15 are used to spray grinding fluid onto the grinding area of ​​the track wheel 4. The grinding fluid can be water. The atomizing nozzles 15 are connected to the output end of the liquid pump through pipes. The liquid pump is connected to the grinding fluid storage tank of the grinding lathe through pipes. A separation box 9 is fixedly installed on one side of the bearing base 1. The separation box 9 is located near the center. A storage tank 17 is fixedly connected to the separation tank 9. The top of the separation tank 9 has an opening for the passage of the grinding fluid and the debris mixture. The top of the storage tank 17 is provided with a first filter plate 10 for separating the grinding fluid and debris. The first filter plate 10 has several filter holes for the passage of the grinding fluid. The bottom of the support base 1 is fixedly provided with a collection box 11 for storing debris. The bottom of the separation tank 9 has a discharge port. The top of the collection box 11 has an inlet corresponding to the discharge port at the middle position.

[0021] In use, the multi-jaw chuck on the fixed seat 2 drives the track wheel 4 to rotate. The first grinding mechanism 7 and the second grinding mechanism 23 grind the surface of the track wheel 4. The liquid pump pumps grinding fluid into the atomizing nozzle 15. The grinding fluid sprays out from the atomizing nozzle 15 to cool the grinding surface of the track wheel 4. The grinding fluid also captures the debris splashed during the grinding process to form a mixture. The mixture enters the separation box 9 from the opening at the top of the separation box 9 and falls onto the first filter plate 10. The first filter plate 10 is set at an inclination. The grinding fluid enters the storage tank 17 through the first filter plate 10 for subsequent suction and processing. The debris slides along the inclined surface of the first filter plate 10 to one side of the separation box 9. After passing through the discharge port, the debris falls into the collection box 11 through the inlet to complete the collection of debris.

[0022] A telescopic mechanism 6 for moving the movable seat 3 is fixedly installed on one side of the top of the support base 1. The telescopic mechanism 6 is an electric push rod, or it can be a hydraulic push rod. The output end of the electric push rod is fixedly connected to the movable seat 3. A shield 5 is fixedly connected to one side of the movable seat 3. The top of the shield 5 is arc-shaped and can be fitted onto the outside of the track wheel 4. The grinding lathe is equipped with an exhaust pipe 16. The number of exhaust pipes 16 is at least multiple, and the number of exhaust pipes 16 is at least one. At least one of the exhaust pipes 16 is fixedly connected to the fixed base 2. An air pump is fixedly installed inside the support base 1. The input end of the air pump is connected to the outside of the grinding lathe. The shield 5 can cover the outside of the exhaust pipe 16. The exhaust pipe 16 is connected to the air pump through a pipe. The exhaust pipe 16 is used to cooperate with the air pump to blow air into the interior of the shield 5, carrying away the mixture between the surface of the rail wheel 4 and the inner wall of the shield 5. One of the multiple exhaust pipes 16 can be set at the top of the liquid storage tank 17 and at the bottom of the first filter plate 10, and is used to blow air into the bottom surface of the first filter plate 10. The airflow carries away debris that may clog the filter holes of the first filter plate 10 through the first filter plate 10. The top of the collection box 11 has connecting grooves 12 on both sides, and the support seat 1 has an exhaust groove 13. The number and position of the exhaust grooves 13 correspond to the number and position of the connecting grooves 12.

[0023] Before the track wheel 4 is fixed to the fixed seat 2, the telescopic mechanism 6 drives the movable seat 3 away from the fixed seat 2, keeping the shield 5 separated from the fixed seat 2. After the track wheel 4 is fixed, the telescopic mechanism 6 drives the movable seat 3 to move until the shield 5 is in contact with the fixed seat 2. The shield 5, together with the support seat 1, the fixed seat 2, and the movable seat 3, forms a closed cavity. The opening of the separation box 9 is connected to the closed cavity. The shield 5 shields the mixture splashed during the grinding process and centrifugally thrown by the track wheel 4, facilitating the subsequent collection by the separation box 9. After grinding, the air pump pumps air into the closed cavity through the exhaust pipe 16. The airflow carries away the mixture from the surface of the track wheel 4 and the inner wall of the shield 5, which facilitates the subsequent cleaning of the track wheel 4 and improves the collection efficiency of the debris. At the same time, the exhaust pipe 16 located in the liquid storage tank 17 back-blown the first filter plate 10. That is, the direction of the airflow acting on the first filter plate 10 is opposite to the filtration direction of the first filter plate 10. This avoids clogging of the first filter plate 10, thus ensuring the separation effect of debris and grinding fluid, while improving the collection efficiency of debris.

[0024] Example 2, as Figures 2-4 and Figure 7Based on Embodiment 1, the first filter plate 10 is rotatably connected to the storage tank 17 via a rotating shaft. A discharge channel is formed between the inner wall of the separation tank 9 and the storage tank 17. The length of the first filter plate 10 is adapted to the size of the corresponding discharge channel. The first filter plate 10 can rotate to block the corresponding discharge channel. An adjusting motor 14 is fixedly installed inside the support 1. The output end of the adjusting motor 14 is connected to the rotating shaft corresponding to the first filter plate 10. The adjusting motor 14 is used to adjust the angle of the first filter plate 10. When the exhaust pipe 16 blows out airflow, the airflow enters the collection box 11 through the discharge channel corresponding to the first filter plate 10, and flows from the connecting groove 12 and... Exhaust is discharged from exhaust trough 13, and debris is retained in collection box 11. When it is necessary to clean the first filter plate 10, the motor 14 is adjusted to drive the first filter plate 10 to rotate, so that the first filter plate 10 separates the discharge channel in the separation box 9 and the cavity connected to the closed cavity. This prevents the blown debris, especially dusty debris, from being carried back into the closed cavity by the airflow and affecting the debris cleaning effect. This allows the exhaust pipe 16 to clean the closed cavity with a stronger airflow, ensuring the cleaning effect of the airflow on the mixture and further improving the reliability of the debris cleaning device. At the same time, the exhaust pipe 16 is only arranged inside the closed cavity to ensure the effective utilization of the airflow.

[0025] Example 3, as Figures 2-5 and Figure 7 Based on Embodiment 2, the number of discharge channels formed by the inner wall of the separation tank 9 and the storage tank 17 is set to two. The top of the separation tank 9 is rotatably connected to a second filter plate 18 via a rotating shaft. The length of the second filter plate 18 is adapted to the size of the corresponding discharge channel. The second filter plate 18 is used to block the top of the storage tank 17 when the first filter plate 10 blocks the corresponding discharge channel. The first filter plate 10 is coaxially fixedly connected to a drive gear 20 via a corresponding rotating shaft. The second filter plate 18 is coaxially fixedly connected to a transmission gear 21 via a corresponding rotating shaft. The interior of the bearing seat 1 is connected to the drive gear 20 via a rotating shaft. A connecting gear 22 is rotatably connected. The driving gear 20 and the transmission gear 21 are both meshed with the connecting gear 22. A sealing mechanism 8 is fixedly connected to one side of the second filter plate 18. The sealing mechanism 8 includes a rotating plate 801, which is fixedly connected to the second filter plate 18. A sliding plate 802 is slidably sleeved on the top of the rotating plate 801. The sliding plate 802 is T-shaped and can slide relative to the rotating plate 801 without disengaging from it. A return spring 803 is fixedly connected to the inner side of the rotating plate 801. One end of the return spring 803 is fixedly connected to the sliding plate 802.

[0026] When cleaning the closed cavity, the adjusting motor 14 drives the first filter plate 10 to rotate, which in turn drives the drive gear 20 to rotate. The drive gear 20, in conjunction with the connecting gear 22 and the transmission gear 21, drives the second filter plate 18 to rotate. When the first filter plate 10 rotates to block the corresponding discharge channel, one end of the second filter plate 18 rotates to the top of the storage tank 17 and the second filter plate 18 is in an inclined state. The body of the second filter plate 18 has several filter holes, allowing debris to enter the collection box 11 through the corresponding discharge channel of the second filter plate 18. The second filter plate 18 drives the rotating plate 801 to rotate 180°. At this time, the sliding plate... Located at the bottom of the rotating plate 801, 802 opens the corresponding discharge channel, thereby preventing debris from entering the storage tank 17 when backflushing the first filter plate 10. After cleaning, the adjusting motor 14 drives the first filter plate 10 to reset, the rotating plate 801 and the sliding plate 802 rotate 180° to reset, the reset spring 803 pushes the sliding plate 802 to extend, and the rotating plate 801 and the sliding plate 802 close the corresponding discharge channel, restricting the airflow and the passage of the mixture, preventing the second filter plate 18 from being blocked by debris, ensuring the normal operation of the debris cleaning device, and further improving the reliability of the debris cleaning device.

[0027] A permanent magnet 804 is fixedly installed on the top of the sliding plate 802, and an electromagnet 19 corresponding to the position of the permanent magnet 804 is fixedly installed on the top of the separation box 9. When the second filter plate 18 needs to be cleaned, after the closed cavity is cleaned, the first filter plate 10 remains in its original position and airflow is generated through the exhaust pipe 16. At the same time, the electromagnet 19 is activated. The force between the electromagnet 19 and the permanent magnet 804 is a repulsive force, and the magnitude of the repulsive force is greater than the elastic force of the return spring 803. This causes the permanent magnet 804 to overcome the elastic force of the return spring 803 and drive the sliding plate 802 to contract. While avoiding the airflow carrying debris, some airflow passes through the gap between the sliding plate 802 and the separation box 9 to clean the debris-receiving surface of the second filter plate 18 in the reverse direction, avoiding the second filter plate 18 from becoming clogged and further improving the reliability of the debris cleaning device.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention.
