The grinding frames 63 are divided into four groups in total, and the two groups of grinding frames 63 on the same side are symmetrical with respect to the central axis of the positioning frame 4, and the two groups of grinding frames 63 in the same row are staggered left and right and their internal structures are arranged in the opposite direction.

[0032] A driven gear 64 is fixedly sleeved on the middle section of the rotating drum 61, and a driving gear 65 is meshed and connected between the two groups of driven gears 64, and a motor 66 is commonly arranged between the center of the driving gear 65 and the corresponding inner wall of the positioning frame 4.

[0037] The second threaded rotating rod 72 is arranged vertically with the first threaded rotating rod 71, and the second motor 73 is arranged at one end of the first threaded rotating rod 71, and the end of the first threaded rotating rod 71 away from the second motor 73 and the top of the second threaded rotating rod 72 are fixedly installed with a steering gear 74, and the two adjacent sets of steering gears 74 are meshed and connected, and the outer end of the first threaded rotating rod 71 and the outer end of the second threaded rotating rod 72 close to the steering gear 74 are movably sleeved with a sliding frame 75, and the threads arranged on the inner wall of the sliding frame 75 through the groove are respectively adapted to the outer walls of the first threaded rotating rod 71 and the second threaded rotating rod 72;

[0038] During specific grinding, the inner wall surfaces of the four groups of grinding frames 63 are respectively close to the multi-side wall surfaces of the two groups of rails, and several groups of grinding discs 710 are respectively fitted with the corresponding wall surfaces, and then the second motor 73 is started to drive the threaded rotating rod 1 71 and the steering gear 74 at its end to rotate, and under the meshing action, the threaded rotating rod 2 72 and the steering gear 74 at its top are driven to rotate, accompanied by the synchronous rotation of the threaded rotating rod 1 71 and the threaded rotating rod 2 72, and the two are respectively rotated relative to the corresponding inner grooves of the sliding frames 75, forcing the two groups of sliding frames 75 to move horizontally or vertically along the outside of the threaded rotating rod 1 71 and the threaded rotating rod 2 72;

[0039] A vertical plate 76 is fixedly installed at the center of one side of the slide frame 75, and a shaft 77 is provided through the center of the vertical plate 76. The shaft 77 and the vertical plate 76 are arranged to intersect in a cross shape. An auxiliary rotating gear 78 is fixedly installed at one end of the shaft 77, and one end of the auxiliary rotating gear 78 extends to a slide groove 79 provided at the inner wall of the positioning frame 4. A tooth groove group is provided at the inner wall of one side of the slide groove 79, and the auxiliary rotating gear 78 meshes with the tooth groove group. A grinding disc 710 is fixedly installed at the other end of the shaft 77;

[0040] During specific operation, along with the movement of the sliding frame 75, the corresponding grinding disc 710 structure is pulled to move, and the grinding surfaces of the two groups of grinding discs 710 on the same side are in contact with the top surface and the side wall of the slide rail respectively, wherein the grinding disc 710 at the top is in contact with the top surface of the slide rail, and the grinding disc 710 moves back and forth horizontally, so as to finely grind the top surface of the slide rail; and the grinding disc 710 on the side is in contact with the side wall of the rail, and moves back and forth longitudinally, so as to finely grind the side wall of the rail, and during the reciprocating movement of the grinding disc 710, the shaft 77 and the auxiliary rotating gear 78 move accordingly, and the auxiliary rotating gear 78 meshes with the tooth groove group to realize the self-rotation of the grinding disc 710, thereby increasing the grinding effect and facilitating the removal of stubborn rust stains on the surface of the rail;

[0041] It is worth noting that an inserting sleeve 711 is sleeved on one end of the shaft rod 77 located at the inner wall of the grinding frame 63. The end of the inserting sleeve 711 away from the shaft rod 77 is used to connect the auxiliary gear 78. The shaft rod 77 is provided with a plurality of groups of sliding bars at equal distances. The sliding bars are correspondingly slidably connected to the long grooves opened on the inner wall of the inserting sleeve 711. A damping spring coil 712 is provided between one end of the shaft rod 77 and the corresponding inner wall of the inserting sleeve 711.

[0042] During the grinding process, since most rails are spliced ​​and the connection points are mostly at the inner wall of the rails, when the grinding disc 710 at the inner wall moves to the rail connection, the grinding disc 710 is pressed by the raised wall surface on the inner side of the rail, and the shaft 77 is pushed to move inside the inserting tube 711, and the damping spring coil 712 is also compressed until the grinding disc 710 passes over the rail connection, and can be reset again under the rebound force of the damping spring coil 712, and the above grinding steps are repeated;

[0043] On the basis of meeting the grinding needs of rails of various sizes, the grinding components can fully contact with the rails in all directions, so as to achieve fine grinding and rust removal of the rails, reduce the occurrence of grinding dead corners, and help improve the grinding and rust removal efficiency of the rails.

Since the outer lines of the oblique grooves on the outer parts of the two sets of movable long rods 62 on the left and right are arranged in opposite directions, the two sets of movable long rods 62 on the left and right sides are forced to move away from each other, and the corresponding grinding frames 63 are pushed to move synchronously until the two left and right sides are aligned. The top inner wall of the grinding frame 63 contacts the top surface of the two sets of rails, and the inner side walls of the opposite sides of the two front and rear grinding frames 63 on the left contact the inner side walls of the two sets of rails respectively. The two front and rear movable long rods 62 on the right are simultaneously inserted into the common rotating drum 61, and pull the corresponding two sets of grinding frames 63 closer to each other. The top inner walls of the two right grinding frames 63 also contact the top surface of the two sets of rails, and the inner wall of the two right grinding frames 63 away from each other contacts the outer side walls of the two sets of rails respectively.

[0046] Next, the linear push device, the scraper sheet 5 contacts and scrapes the surface of the sleeper to assist in removing the dirt on the surface, and at the same time, a plurality of groups of grinding frames 63 slide relative to the rails, and the grinding frames 63 are used to fit and grind the contact surface of the rails;

[0047] At the same time, several groups of grinding discs 710 are respectively fitted with the corresponding wall surfaces, and then the motor 2 73 is started to drive the threaded rotating rod 1 71 and the steering gear 74 at its end to rotate. Under the meshing action, the threaded rotating rod 2 72 and the steering gear 74 at its top are driven to rotate, accompanied by the synchronous rotation of the threaded rotating rod 1 71 and the threaded rotating rod 2 72, and the two are respectively rotated relative to the corresponding inner grooves of the sliding frame 75, forcing the two groups of sliding frames 75 to move horizontally or vertically along the outside of the threaded rotating rod 1 71 and the threaded rotating rod 2 72, and the sliding frame 75 pulls the grinding disc 710 structure to move, and the two groups on the same side The grinding surfaces of the grinding disc 710 are in contact with the top surface and side wall of the slide rail respectively, wherein the grinding disc 710 at the top is in contact with the top surface of the slide rail, and the grinding disc 710 reciprocates laterally so as to finely grind the top surface of the slide rail; while the side grinding disc 710 is in contact with the side wall of the rail, and reciprocates longitudinally so as to finely grind the side wall of the rail, and during the reciprocating movement of the grinding disc 710, the shaft 77 and the auxiliary rotating gear 78 move accordingly, and the auxiliary rotating gear 78 meshes with the tooth groove group to realize the self-rotation of the grinding disc 710, thereby increasing the grinding effect and facilitating the removal of stubborn rust stains on the surface of the rail.
