Description

[0001] This application is a divisional application with the application date of May 31, 2024, application number CN2024106961843, and the invention name is A high-speed rail workpiece processing device. Technical Field

[0002] The invention relates to the technical field of high-speed railway tracks, and in particular to a high-speed railway track workpiece processing device. Background Art

[0003] When laying rails, thermite welding is usually used to connect two adjacent rails. Thermite welding means that when welding, the ends of the two workpieces to be welded are fixed in a mold in advance, and then a mixture of aluminum powder and iron oxide powder (called thermite) is placed in a crucible and heated to cause a reduction exothermic reaction to form liquid metal (iron) and slag (mainly Al2O3), which are then injected into the mold.

[0004] After welding, in order to ensure the stability of the connection and the stability of the train running above, it is necessary to remove the welding slag from the welding part and grind the welding part. At present, manual removal and grinding are usually adopted when removing the welding slag and grinding. The excess welding slag on the rail is scraped off manually with a handheld shovel, and then the welding part is grinded with a handheld small grinder. The efficiency of welding slag treatment is not high, the grinding speed is slow, and labor and time are wasted. According to the comparative document disclosure (announcement) number CN110983882B, a rail grinding device that can adapt to rails of different distances is disclosed, including a fuselage, wherein left and right sliding cavities with openings upward are provided in the fuselage, and left and right sliding rails are provided on the lower walls of the left and right sliding cavities. The left and right slide rails are provided with left and right sliding blocks, and a sliding block spring is fixedly provided on the left outer surface of the left and right sliding blocks, a switching cavity is provided below the left and right sliding cavities, and a through hole for setting a position is provided above the left and right sliding cavities, a transmission cavity is provided on the right side of the switching cavity, a rotatable second rotating rod is provided in the transmission cavity, a locking cavity is provided on the right side of the transmission cavity, the second rotating rod extends left and right into the switching cavity and the locking cavity, and a braking snap ring for locking is provided in the locking cavity. The present invention can also lock the position between the two after the distance between the grinding knives is adjusted, so as to prevent the grinding knife distance from changing due to vibration or other reasons during the grinding process, thereby affecting the grinding quality.

[0005] However, in actual use, the device in the comparative document has poor grinding effect when grinding the welding points, and it is not convenient to replace the grinding wheel. At the same time, it is not stable and practical. For this reason, technical personnel in this field disclosed a high-speed rail workpiece processing device. Summary of the invention

[0039] For further information, see Figure 4 The grinding mechanism 6 includes a rotating rod 61 which is horizontally rotatably mounted on opposite sides of the opening of the mounting frame 5. A grinding wheel 62 which contacts the top of the rail is fixedly sleeved on the rotating rod 61. A vertically arranged rotating rod 63 is rotatably mounted on opposite sides of the opening of the mounting frame 5 through a bearing assembly. Two bevel gears 64 are fixedly sleeved on the rotating rod 61. The tops of the two rotating rods 63 are fixedly sleeved with bevel gears 65. The two bevel gears 65 are respectively meshed with the two bevel gears 64. Grinding wheels 66 are detachably sleeved on the two rotating rods 63. The two grinding wheels 66 are respectively in contact with the two sides of the rail. A motor 67 is fixed on one side of the mounting frame 5, and one end of the motor 67 is movably inserted into the interior of the mounting frame 5 and fixedly connected to one end of the rotating rod 61. A protective shell 1 mounted on a motor 167 is detachably mounted on the mounting frame 5 by bolts. When the device is used to grind the weld of the rail, the motor 167 is started, and the output shaft of the motor 167 rotates, driving the rotating rod 161 to rotate. The rotation of the rotating rod 161 drives the grinding wheel 162 to rotate, and the top of the weld is grinded. At the same time, the rotation of the rotating rod 161 drives the two fixed bevel gears 164 to rotate. The two bevel gears 164 respectively drive the meshing bevel gears 265 to rotate, thereby rotating the two rotating rods 263, and the grinding wheels 266 on the two rotating rods 263 rotate to grind the sides of the weld. The grinding effect is better, and the three sides of the weld connected in sequence can be grinded at the same time. The grinding efficiency is high, saving time and labor costs.

[0040] Since the rail is an I-shaped rail, in order to ensure that the device can be mounted on the rail, the grinding wheel 266 can only be installed when the mobile frame 1 is mounted on the rail. Figure 5, a fixed sleeve of the rotating rod 63 is provided with a fixing piece 1 631, a grinding wheel 2 66 is movably sleeved on the rotating rod 63 and the top is tightly fitted with the bottom of the fixing piece 1 631, a fixing piece 2 632 is movably sleeved on the rotating rod 63 and the top of the fixing piece 2 632 is tightly fitted with the bottom of the grinding wheel 2 66, an internal thread structure is provided at the end of the rotating rod 63 and a fastening bolt 633 is provided on the threaded sleeve, and the top of the fastening bolt 633 is tightly fitted with the bottom of the fixing piece 2 632. In order to further improve the effect of grinding the side of the rail, two grinding wheels 2 66 of different sizes are installed on the same rotating rod 63. First, part of the fixing piece 2 632 is sleeved on the rotating rod 63, And it conflicts with the fixing piece 1 631, then a grinding wheel 2 66 with a smaller diameter is sleeved on the rotating rod 2 63, so that the outer peripheral side of the grinding wheel 2 66 with a smaller diameter contacts a convex part of the side surface of the rail, and then a part of the fixing piece 2 632 is sleeved on the rotating rod 2 63 to fit with the grinding wheel 2 66 with a smaller diameter, and then the grinding wheel 2 66 with a larger diameter is sleeved on the rotating rod 2 63, so that the grinding wheel 2 66 with a larger diameter contacts a concave part of the side surface of the rail, and finally a suitable number of fixing pieces 2 632 are sleeved, and the fastening bolts 633 are installed at the ends of the rotating rod 2 63 to fix the two grinding wheels 2 66. At this time, the grinding wheel 2 66 can be rotated to grind the welding parts of the rail.

[0041] Further, in order to improve the grinding effect of the grinding wheel 1 62 and the grinding wheel 2 66 on the rail welding part, please refer to Figure 2 and Figure 6 , U-shaped frame 1 11 and U-shaped frame 2 12 are both rotatably mounted with vertical device rods 14, the control mechanism 7 includes two rotating wheels 71, the two rotating wheels 71 are respectively fixedly sleeved on the bottom ends of the two device rods 14, the two rotating wheels 71 are eccentrically rotated and the circumferential sides of the two rotating wheels 71 are respectively in conflict with the two opposite sides of the mounting frame 5, the eccentric positions of the two rotating wheels 71 are the same, the two device rods 14 are both fixedly sleeved with transmission wheels 72, and an integrated transmission belt 73 is sleeved between the two transmission wheels 72, the end of one of the device rods 14 movably passes through the connecting plate 13 and is fixedly sleeved with a worm gear 74, a motor 2 75 is installed on the connecting plate 13, and a motor 2 75 is fixed on the output end of the motor 2 75 The worm 76 meshing with the worm wheel 74 starts the motor 2 75. The output end of the motor 2 75 rotates to drive the worm 76 to rotate. The worm 76 drives the meshing worm wheel 74 to rotate. The worm wheel 74 drives the connected device rod 14 to rotate. The device rod 14 rotates and drives the transmission wheel 72 to rotate. The other transmission wheel 72 is driven to rotate synchronously through the transmission belt 73. The two device rods 14 rotate synchronously, thereby driving the two rotating wheels 71 to rotate synchronously. Since the two rotating wheels 71 are arranged in an array, the synchronous rotation of the two rotating wheels 71 will conflict with the mounting frame 5 under the guidance of the connecting rod 51, and reciprocate, so that the grinding wheel 1 62 and the grinding wheel 2 66 can better grind the rails.

[0042] In order to improve the smoothness of the reciprocating motion of the mounting frame 5, please refer to Figure 3 and Figure 4 A connecting groove 15 sleeved on the connecting rod 51 is provided on the opposite side of the U-shaped frame 11 and the U-shaped frame 2 12. A stopper 52 located inside the connecting groove 15 is installed on the connecting rod 51. A spring 53 movably sleeved on the connecting rod 51 is connected between the stopper 52 and the inner wall of the connecting groove 15. When the rotating wheel 71 on one side abuts against the mounting frame 5 and moves toward the other side, the connecting rod 51 on the other side drives the stopper 52 to penetrate inside the connecting groove 15, which compresses the corresponding spring 53 and generates elastic force to abut against the stopper 52, so as to facilitate the resetting of the mounting frame 5. Under the elastic force of the springs 53 on both sides, the mounting frame 5 can move better.

[0043] For further information, see Figure 2 and Figure 8 Four rectangular mounting blocks 16 are installed at the bottom of the mobile frame 1. The four mounting blocks 16 are evenly distributed on the U-shaped frame 11 and the U-shaped frame 2 12 and are located on the side opposite to the U-shaped frame 11 and the U-shaped frame 2 12. The number of the fixing mechanisms 8 is four and they are respectively installed on the four mounting blocks 16. The fixing mechanism 8 includes a threaded rod 81 that horizontally threads through the mounting block 16. One end of the threaded rod 81 corresponds to the side of the rail and is fixed with a fixing block 82. The other end of the threaded rod 81 is fixed with a knob 83. When the grinding mechanism 6 needs to grind the welding part, in order to ensure the stability of the device and the grinding effect, the knob 83 is turned to drive the threaded rod 81 to rotate. The fixing block 82 at one end of the threaded rod 81 contacts the side of the rail. The four fixing blocks 82 can make the device more stable and the grinding effect is better.

When the mobile frame 1 is set on the rail, after the roller 12 contacts the top of the rail, the control rod 123 controls the support rod 121 to slide along one side of the U-shaped frame 2 12, so that the roller 2 122 fits the side of the rail, and then the positioning rod 125 is rotated to insert one end of the positioning rod 125 into the corresponding positioning groove 124 to fix the support rod 121. The setting of one roller 12 and two rollers 122 can make the device more stable when moving.
