Description

Technical Field

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

[0002] During the production and processing of rail wheels, it is necessary to use a grinding lathe to grind the curved surface and side surfaces of the rail wheels so that the contact surface of the rail wheels and the rails can remain in contact during subsequent operation. The existing rail wheel grinding lathe includes a lathe, on which a multi-jaw chuck is fixedly provided. When in use, the rail wheel is fixedly clamped on the multi-jaw chuck, and the multi-jaw chuck drives the rail wheel to rotate. Two grinding mechanisms arranged on the lathe grind the side and arc surface of the rail wheel respectively. In order to reduce the dispersion of dust during the grinding process and avoid overheating, some grinding lathes are fixedly provided with an atomizing nozzle, which is connected to the output end of the liquid pump through a pipeline, and the input end of the liquid pump is connected to a liquid storage tank containing grinding liquid through a pipeline. During the grinding process, the atomizing nozzle sprays the grinding liquid onto the grinding surface, and the mixed liquid of the debris and the grinding liquid falls to the filter net on the lathe under the action of gravity. The liquid is stored in the sewage tank after passing through the filter net, and the debris is driven to the collection box for collection by the reciprocating movement of the scraper driven by the telescopic mechanism arranged on the lathe.

[0003] However, during the use of traditional rail wheel grinding lathes, the grinding fluid sprayed onto the rail wheel is mixed with debris and rotated 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 debris cleaning effect and difficulty in collecting the thrown grinding fluid and debris. In addition, the filter is easily clogged by fine debris. As the use time increases, it is difficult for the grinding fluid to be effectively separated from the debris on the filter, resulting in a decrease in the debris cleaning effect. Summary of the invention

[0004] The present application proposes a debris cleaning device for rail wheel grinding, which has the advantages of avoiding filter hole blockage and improving the cleaning effect, and is used to solve the problem that the mixed liquid of grinding fluid and debris is easily thrown away and the separation effect is poor.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a debris cleaning device for rail wheel grinding, comprising a bearing seat, a fixed seat is fixedly arranged on one side of the top of the bearing seat, a movable seat is slidably arranged on one side of the top of the bearing seat, the bearing seat, the fixed seat and the movable seat constitute a grinding lathe, a separation box is fixedly arranged on one side inside the bearing seat, a liquid storage tank is fixedly connected to the middle position inside the separation box, a filter plate for separating grinding fluid and debris is arranged on the top of the liquid storage tank, a collection box for storing debris is fixedly arranged on the bottom of the bearing seat, and a telescopic mechanism for driving the movable seat to move is fixedly arranged on one side of the top of the bearing seat;

[0006] A shielding cover is fixedly connected to one side of the movable seat, and the top of the shielding cover is arranged in an arc shape. An exhaust pipe is arranged on the grinding lathe, and the shielding cover can fit together with the fixed seat to cooperate with the bearing seat, the fixed seat and the movable seat to form a closed cavity. The exhaust pipe can discharge the airflow to clean the closed cavity, and the direction of the airflow acting on the No. 1 filter plate is opposite to the filtering direction of the No. 1 filter plate.

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

[0008] The present application provides a debris cleaning device for rail wheel grinding, which drives a movable seat to move through a telescopic mechanism, so that a closed cavity is formed between the movable seat, the shielding cover, the fixed seat and the bearing seat, thereby limiting the splashing of debris and grinding fluid, and preventing the grinding fluid and debris mixture from being centrifugally thrown out of the lathe by the rotating rail wheel. In conjunction with the exhaust pipe, an airflow for cleaning the closed cavity is formed, thereby ensuring the cleaning effect of the debris and the grinding fluid, and the airflow acts in the reverse direction on the No. 1 filter plate, so that the airflow blows open the filter holes blocked by the debris, thereby achieving the effect of improving the collection and cleaning of the debris while avoiding the blockage of the No. 1 filter plate.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Two atomizing nozzles 15 are arranged on one side of the fixed seat 2, and 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 nozzle 15 is used to spray the grinding liquid to the grinding position of the rail wheel 4. The grinding liquid can be set to clean water. The atomizing nozzle 15 is connected to the output end of the liquid pump through a pipeline, and the liquid pump is connected to the grinding liquid storage tank of the grinding lathe through a pipeline. A separation box 9 is fixedly arranged on one side of the bearing seat 1. The separation box 9 is located near the middle position. A liquid storage tank 17 is fixedly connected to the support seat 1, an opening is provided on the top of the separation box 9 for the passage of a mixture of grinding liquid and debris, a filter plate 10 for separating grinding liquid and debris is provided on the top of the liquid storage tank 17, and a plurality of filter holes are provided on the plate body of the filter plate 10 for the passage of grinding liquid, a collecting box 11 for storing debris is fixedly provided on the bottom of the support seat 1, a discharge port is provided at the bottom of the separation box 9, and a feed port corresponding to the position of the discharge port is provided at the middle position of the top of the collecting box 11.

[0021] When in use, the multi-claw chuck on the fixed seat 2 drives the rail wheel 4 to rotate, and the No. 1 grinding mechanism 7 and the No. 2 grinding mechanism 23 grind the surface of the rail wheel 4. The liquid pump pumps grinding liquid into the atomizing nozzle 15, and the grinding liquid is sprayed from the atomizing nozzle 15 to cool the grinding surface of the rail wheel 4. The grinding liquid captures the debris splashed during the grinding process to form a mixed liquid, and the mixed liquid enters the separation box 9 from the opening at the top of the separation box 9 and falls on the No. 1 filter plate 10. The No. 1 filter plate 10 is arranged at an angle. The grinding liquid enters the liquid storage tank 17 through the No. 1 filter plate 10, which is convenient for subsequent suction and processing. The debris slides to one side of the separation box 9 along the inclined surface of the No. 1 filter plate 10, and the debris passes through the discharge port and then falls into the collection box 11 through the feed port of the collection box 11 to complete the collection of the debris.

[0022] A telescopic mechanism 6 for driving the moving seat 3 to move is fixedly arranged on one side of the top of the bearing seat 1. The telescopic mechanism 6 is arranged as an electric push rod. The telescopic mechanism 6 can also be arranged as a hydraulic push rod. The output end of the electric push rod is fixedly connected to the moving seat 3. A shielding cover 5 is fixedly connected to one side of the moving seat 3. The top of the shielding cover 5 is arranged in an arc shape. The shielding cover 5 can be sleeved on the outside of the rail wheel 4. An exhaust pipe 16 is arranged on the grinding lathe. The number of exhaust pipes 16 is at least set to multiple, and the number of exhaust pipes 16 is at least one. At least one exhaust pipe 16 among the several exhaust pipes 16 is fixedly connected to the fixed seat 2. An air pump is fixedly arranged in the bearing seat 1. The input end of the air pump is connected to the air outside the grinding lathe. The shielding cover 5 is connected, and the shielding cover 5 can shield the outside of the exhaust pipe 16. The exhaust pipe 16 is connected to the air pump through a pipeline. The exhaust pipe 16 is used to cooperate with the air pump to blow air into the shielding cover 5 to take away the mixed liquid on the surface of the rail wheel 4 and the inner wall of the shielding cover 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 No. 1 filter plate 10, and is used to blow air to the bottom surface of the No. 1 filter plate 10. The airflow passes through the No. 1 filter plate 10 and brings up debris that may be blocked in the filter holes of the No. 1 filter plate 10. Connecting grooves 12 are provided on both sides of the top of the collecting box 11, and exhaust grooves 13 are provided in the supporting seat 1. The number and position of the exhaust grooves 13 correspond to the number and position of the connecting grooves 12.

[0023] Before the rail wheel 4 is fixed on the fixed seat 2, the telescopic mechanism 6 drives the movable seat 3 to move away from the fixed seat 2, so that the shielding cover 5 remains separated from the fixed seat 2. After the rail wheel 4 is fixed, the telescopic mechanism 6 drives the movable seat 3 to move until the shielding cover 5 is in contact with the fixed seat 2. The shielding cover 5, the bearing seat 1, the fixed seat 2 and the movable seat 3 form a closed cavity. The opening of the separation box 9 is connected to the closed cavity. The shielding cover 5 shields the mixed liquid splashed during the grinding process and thrown away by the rail wheel 4, which is convenient for the subsequent collection of the separation box 9 Separation, after grinding is completed, the air pump pumps air into the closed cavity through the exhaust pipe 16, and the airflow takes away the mixed liquid on the surface of the rail wheel 4 and the inner wall of the shielding cover 5, which is convenient for the subsequent cleaning of the rail wheel 4 and improves the collection efficiency of debris. At the same time, the exhaust pipe 16 located in the liquid storage tank 17 back-blows the No. 1 filter plate 10, that is, the direction of the airflow acting on the No. 1 filter plate 10 is opposite to the filtering direction of the No. 1 filter plate 10, thereby avoiding the blockage of the No. 1 filter plate 10 and ensuring the separation effect of debris and grinding liquid, while improving the collection efficiency of debris.

[0024] Embodiment 2, as Figure 2-Figure 4 and Figure 7On the basis of the first embodiment, the first filter plate 10 is rotatably connected with the liquid storage tank 17 through the rotating shaft, and a discharge channel is formed between the inner wall of the separation box 9 and the liquid 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 be rotated to block the corresponding discharge channel. An adjusting motor 14 is fixedly arranged inside the bearing seat 1. The output end of the adjusting motor 14 is drivingly connected with 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 the airflow, the airflow enters the collection box 11 through the discharge channel corresponding to the first filter plate 10, and enters the collection box 11 from the connecting groove 12 and The exhaust groove 13 is discharged, and the debris is retained in the collection box 11. When the No. 1 filter plate 10 needs to be cleaned, the adjustment motor 14 drives the No. 1 filter plate 10 to rotate, so that the No. 1 filter plate 10 separates the discharge channel in the separation box 9 and the cavity connected to the closed cavity, so that the blown debris, especially the dusty debris, will not be driven back into the closed cavity by the airflow and affect the cleaning effect of the debris, so that the exhaust pipe 16 can use a stronger airflow to clean the closed cavity, ensuring the cleaning effect of the airflow on the mixed liquid, and further improving the reliability of the debris cleaning device. At the same time, the exhaust pipe 16 is only arranged on the inner side of the closed cavity to ensure the effective use of the airflow.

[0025] Embodiment three, as Figure 2-Figure 5 and Figure 7 On the basis of the second embodiment, the number of discharge channels formed by the inner wall of the separation box 9 and the liquid storage box 17 is set to two, and the top of the separation box 9 is rotatably connected with a No. 2 filter plate 18 through a rotating shaft. The length of the No. 2 filter plate 18 is adapted to the size of the corresponding discharge channel. The No. 2 filter plate 18 is used to cover the top of the liquid storage box 17 when the No. 1 filter plate 10 covers the corresponding discharge channel. The No. 1 filter plate 10 is coaxially fixedly connected to the driving gear 20 through the corresponding rotating shaft, and the No. 2 filter plate 18 is coaxially fixedly connected to the transmission gear 21 through the corresponding rotating shaft. The interior of the bearing seat 1 is connected by the rotating shaft. A connecting gear 22 is rotatably connected, and the driving gear 20 and the transmission gear 21 are meshed with the connecting gear 22. A closing mechanism 8 is fixedly connected to one side of the No. 2 filter plate 18. The closing mechanism 8 includes a rotating plate 801, and the rotating plate 801 is fixedly connected to the No. 2 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 separating from the rotating plate 801. A return spring 803 is fixedly connected to the inner side of the rotating plate 801, and one end of the return spring 803 is fixedly connected to the sliding plate 802.

[0026] When cleaning the closed cavity, the regulating motor 14 drives the No. 1 filter plate 10 to rotate, and the transmission drives the driving gear 20 to rotate. The driving gear 20 cooperates with the connecting gear 22 and the transmission gear 21 to drive the No. 2 filter plate 18 to rotate. When the No. 1 filter plate 10 rotates to block the corresponding discharge channel, one end of the No. 2 filter plate 18 rotates to the top of the liquid storage tank 17 and the No. 2 filter plate 18 is in an inclined state. The plate body of the No. 2 filter plate 18 is provided with a plurality of filter holes, so that the debris can enter the collection box 11 through the discharge channel corresponding to the No. 2 filter plate 18. The No. 2 filter plate 18 drives the rotating plate 801 to rotate 180°. At this time, the sliding plate 802 is located at the bottom of the rotating plate 801, opening the corresponding discharge channel, thereby preventing debris from entering the liquid storage tank 17 when backblowing the No. 1 filter plate 10. After cleaning is completed, the adjusting motor 14 drives the No. 1 filter plate 10 to reset, and 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 mixed liquid from passing through, avoiding the No. 2 filter plate 18 from being blocked by debris, ensuring the normal operation of the debris cleaning device, and further improving the reliability of the use of the debris cleaning device.

[0027] A permanent magnet 804 is fixedly provided on the top of the sliding plate 802, and an electromagnet 19 corresponding to the position of the permanent magnet 804 is fixedly provided on the top of the separation box 9. When it is necessary to clean the No. 2 filter plate 18, after the closed cavity is cleaned, the No. 1 filter plate 10 remains in place, and airflow is generated through the exhaust pipe 16. At the same time, the electromagnet 19 is started, and the acting 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 reset spring 803, so that the permanent magnet 804 overcomes the elastic force of the reset spring 803 to drive the sliding plate 802 to contract. Under the condition of avoiding the airflow carrying debris, part of the airflow passes through the gap between the sliding plate 802 and the separation box 9 to reversely clean the debris receiving surface of the No. 2 filter plate 18, so as to avoid congestion of the No. 2 filter plate 18 and further improve the reliability of the use of the debris cleaning device.

Various modifications to these embodiments will be apparent to one 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 present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
