Description

Technical Field

[0001] The utility model relates to an on-line processing device for a rail, belonging to the field of rail laser processing equipment. Background Art

[0002] Rail laser processing is a method of strengthening rails using laser technology. Through laser processing, high-precision and high-efficiency rail processing can be achieved with smaller deformation and heat-affected areas. Laser processing can be used to trim and repair damaged rails, and can also be customized on newly laid railway lines. This processing method has broad application prospects in railway maintenance and construction.

[0003] In the prior art, rails are strengthened by an online rail processing device, which can only perform laser strengthening and repair on a single side of the rail at a time. After completing one side, the online rail processing device must be turned around and the other side must be processed. In addition, the unit processing efficiency is low (less than 30 meters / hour on a single side), which seriously affects the processing efficiency of the actual laser processing of the rails and is not suitable for on-site operation needs.

[0004] In summary, the utility model therefore provides an online rail processing device to solve the above-mentioned problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model aims to provide an online processing device for rails to solve the problem of low efficiency of rail laser strengthening processing mentioned in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a rail online processing device, comprising a processing lathe main body and a base plate, the base plate is fixedly connected to the top of the processing table of the processing lathe main body, both sides of the top of the base plate are fixedly connected with a fixing plate, both sides of the top of the two fixing plates are fixedly connected with a mounting plate, a slide groove is opened between the top and the bottom of the mounting plate, both sides of the top of the mounting plate and above the slide groove are provided with sliding plates, the bottoms of the two sliding plates and the inside of the slide groove are fixedly connected with sliders, the bottoms of the two sliding plates and the bottoms of the mounting plates are fixedly connected with limiting plates, the bottoms of the two limiting plates are fixedly connected with transmission plates, the tops of the two sliding plates are mirror-symmetrically fixedly installed with rail turning clamps, one side of the fixed plate is fixedly connected with a first chassis, the inside of the first chassis is fixedly connected with a servo motor, and the output end of the servo motor is fixedly connected with a bidirectional screw rod.

[0007] Furthermore, one end of the bidirectional lead screw sequentially passes through the first chassis, a fixed plate and two transmission plates and extends to one side of another fixed plate.

[0008] Furthermore, the bidirectional screw rod is rotationally connected to the first chassis, and the bottoms of the two sliding plates are slidably connected to the top of the mounting plate through sliding blocks and sliding grooves.

[0009] Furthermore, the bidirectional screw rods are rotatably connected to the two fixed plates, and the bidirectional screw rods are threadedly connected to the two transmission plates.

[0010] Furthermore, the two limit plates are slidably connected to the bottom of the mounting plate via two sliding plates, and the limit plates have a limiting effect on the transmission plate.

[0011] Furthermore, the rail flipping fixture includes a connecting plate, which is fixedly connected to the top of the sliding plate, one side of the connecting plate is fixedly connected to a second chassis, the interior of the second chassis is fixedly connected to a driving motor, the output end of the driving motor is fixedly connected to a driving shaft, one end of the driving shaft passes through the second chassis and the connecting plate in sequence and extends to the other side of the connecting plate, one end of the driving shaft is fixedly connected to a flipping plate, and both sides of the flipping plate away from the driving shaft are fixedly connected to clamping plates.

[0012] Furthermore, an electromagnet plate is fixedly connected to a side of the flip plate away from the driving shaft and located between the two clamping plates, and the driving shaft is rotatably connected to the second chassis.

[0013] Furthermore, the driving shaft is rotatably connected to the connecting plate, and the top and bottom of the flip plate are both in an arc shape.

[0014] Beneficial effects of the utility model:

[0015] By starting the servo motor output end and rotating the switch clockwise, the two sliding plates can be driven to slide towards each other on the top of the mounting plate, and the rail can be clamped between the two electromagnet plates and located between every two clamping plates. The driving motor inside the two rail flipping clamps is started to drive the two flipping plates to rotate, and then the rail can be clamped by the two clamping plates and flipped 180°, so that after the rail online processing device completes the strengthening treatment on one side of the rail, the other side of the rail can be laser processed without turning the rail online processing device around, which effectively improves the efficiency of laser strengthening processing of the rail and meets the needs of on-site operations.

[0016] When the rail is flipped, after the bottom of the rail and the top of the mounting plate are tilted, the two electromagnet plates are started to magnetically fix the two ends of the rail to prevent the rail from falling from between the clamping plates during flipping. When the two electromagnet plates rotate 180°, the two drive motors are turned off to flip the rail 180° and swap the unprocessed and processed surfaces of the rail. The electromagnet plates are then turned off to fix the two ends of the rail. The rail slides from top to bottom between the two clamping plates inside the two rail flipping fixtures to the top of the mounting plate, which improves the positioning processing accuracy after the rail is flipped, and effectively improves the quality and stability of the rail laser processing.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

The output end of the servo motor 6 is fixedly connected with a bidirectional screw rod 7. The processing lathe body 1 is mainly composed of a plasma generator, a generator power supply, a water cooler, a generator set, an air compressor, a dryer, and a sandblasting device. There are fourteen plasma generators, which are powered by fourteen power supplies respectively. There are seven plasma generators staggered on the left and right sides of the lathe of the processing lathe body 1. The top surface of the rail and the inner side of the rail are strengthened by high-temperature plasma. After the plasma generator is treated, the sandblasting device sandblasts the top surface and the inner side of the rail. The plasma generator and the sandblasting device are set on both sides of the lathe of the processing lathe body 1. The top surface of the rail and the inner side of the rail are strengthened by high-temperature plasma. The hardness can reach above RHC60, which increases the wear resistance of the rail and extends the service life of the rail. The sandblasting device can eliminate the local stress generated by the strengthening treatment.

[0026] See also Figure 2-5 The two ends of the two-way screw rod 7 pass through the first chassis 5, a fixed plate 3 and two transmission plates 13 in sequence and extend to one side of the other fixed plate 3. The two-way screw rod 7 is rotatably connected to the first chassis 5. The bottoms of the two sliding plates 10 are slidably connected to the top of the mounting plate 4 through the slider 11 and the slide groove 8. The two-way screw rod 7 is rotatably connected to the two fixed plates 3. The two-way screw rod 7 is threadedly connected to the two transmission plates 13. The two limit plates 12 are slidably connected to the bottom of the mounting plate 4 through the two sliding plates 10. The limit plate 12 has a limiting effect on the transmission plate 13. The thread directions of the two transmission plates 13 at the threaded sleeves are opposite. When the two-way screw rod 7 rotates clockwise, the two transmission plates 13 can be driven to slide close to each other. When the two-way screw rod 7 rotates counterclockwise, the two transmission plates 13 can be driven to slide away from each other. The width of the slide groove 8 is smaller than the width of the rail, so that the rail placed on the top of the mounting plate 4 will not be stuck in the inside of the slide groove 8.

[0027] See also Figure 3-5 The rail flipping fixture 9 includes a connecting plate 91, which is fixedly connected to the top of the sliding plate 10, and a second chassis 92 is fixedly connected to one side of the connecting plate 91. A driving motor 93 is fixedly connected to the interior of the second chassis 92, and an output end of the driving motor 93 is fixedly connected to a driving shaft 94. One end of the driving shaft 94 passes through the second chassis 92 and the connecting plate 91 in sequence and extends to the other side of the connecting plate 91. One end of the driving shaft 94 is fixedly connected to a flip plate 95, and both sides of the flip plate 95 away from the driving shaft 94 are fixedly connected to clamps 96. The driving motor 93 is connected to an external power supply and is provided with a power control switch. The output ends of the driving motors 93 inside the two rail flipping fixtures 9 rotate in opposite directions, and then the rails can be fixed by the two rail flipping fixtures 9 and flipped in the same direction.

[0028] See also Figure 3-5 The flip plate 95 is away from the side of the driving shaft 94 and is fixedly connected with an electromagnet plate 97 between the two clamping plates 96. The driving shaft 94 is rotatably connected to the second chassis 92, and the driving shaft 94 is rotatably connected to the connecting plate 91. The top and bottom of the flip plate 95 are both in an arc shape, so that when the driving shaft 94 drives the flip plate 95 to flip, the flip plate 95 will not rub against the top of the mounting plate 4. The electromagnet plates 97 inside the two rail flipping fixtures 9 are connected to an external power supply and are provided with the same power switch. When the power of the two electromagnet plates 97 is started, the two electromagnet plates 97 can magnetically fix the two ends of the rail by magnetic attraction.

[0029] Specific implementation method: By placing the rail to be processed on the top of the mounting plate 4 inside the processing lathe body 1 and between the two rail flipping clamps 9, the plasma generator and the sandblasting device inside the processing lathe body 1 are started, and the top surface of the rail and the inner side surface of the rail are strengthened by high-temperature plasma. The hardness can reach above RHC60, thereby increasing the wear resistance of the rail and extending the service life of the rail. The sandblasting device can eliminate the local stress generated by the strengthening treatment. After the top surface of the rail and the inner side surface of the rail are strengthened, the rail needs to be flipped.

[0030] By starting the clockwise rotation switch at the output end of the servo motor 6, the bidirectional lead screw 7 is driven to rotate clockwise, so that the two transmission plates 13 slide close to each other at the bottom of the mounting plate 4 through the two sliders 11 and the slide groove 8, and then the two sliding plates 10 can be driven to slide close to each other at the top of the mounting plate 4, so that the two rail flipping clamps 9 can be driven to move close to each other, shorten the spacing, and clamp the rail between the two electromagnet plates 97, and between every two clamping plates 96, and start the driving motor 93 inside the two rail flipping clamps 9, so as to drive the two flipping plates 95 to rotate, and then the rail can be clamped by the two clamping plates 96 for flipping. When the rail is flipped, the bottom of the rail and the top of the mounting plate 4 are tilted, and the two electromagnet plates 97 are started to magnetically fix the two ends of the rail to prevent the rail from falling from between the clamping plates 96 during the flipping process.

[0031] When the two electromagnet plates 97 rotate 180°, the two drive motors 93 are turned off, so that the rail is flipped 180° and the unprocessed surface and the processed surface of the rail are swapped. Then the electromagnet plates 97 are turned off, so that the two ends of the rail are no longer fixed, and the rail slides from top to bottom between the two clamping plates 96 inside the two rail flipping clamps 9 to the top of the mounting plate 4. The servo motor 6 output end is started to rotate the switch counterclockwise, which can drive the two rail flipping clamps 9 to slide away from each other and reset, so that the flipped rail can be strengthened.

[0032] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
