Turnouts, in particular, are one of the three weakest links in railways, along with curves and joints, due to their large number, complex structure, short service life, speed restrictions, low operating safety, and high maintenance costs.
[0003] When the rails on a railway line are subjected to a certain degree of rolling, their contour shape changes, and the contact geometry between the wheelset and the rails deteriorates, which impairs the smoothness of operation and the service life of the rails.

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1 -Attached Figure 5 , further details of this application are given.
[0033] Example 1
[0034] A deflection mechanism for intelligent rail dressing and grinding equipment, referring to Figure 1 、 Figure 2 and Figure 3 The invention comprises a turbine chamber 1, which houses a worm gear 2 and a worm 3. The axes of the worm gear 2 and the worm 3 are perpendicular to each other. The worm gear 2 and the worm 3 mesh with each other, and the worm 3 is rotatably connected within the turbine chamber 1. A mounting plate 4 is provided on one side of the worm gear 2 for mounting a grinding device. The grinding device is a conventional device for grinding rails. The end surface of the mounting plate 4 is perpendicular to the axis of the worm gear 2.
[0035] A drive assembly 5 for rotating the worm gear 3 is provided on one side of the turbine chamber 1. This assembly includes an offset reduction motor 51, the output shaft of which is fixedly connected to a driving gear 52, which is coaxially arranged with the output shaft of the reduction motor 51. A transmission housing 10 is provided outside the driving gear 52, which is fixedly connected to the housing of the offset reduction motor 51.
[0036] A hexagonal gear 53 meshes with one side of the driving gear 52. A hexagonal sleeve 6 is inserted through the center of the hexagonal gear 53 and fixedly connected to the transmission housing 10. A hexagonal shaft 9 is fixedly connected to the inner surface of the hexagonal sleeve 6. A positioning sleeve 7 and a nylon sleeve 8 are fixedly connected to the outer wall of the hexagonal sleeve 6 to improve the rotational stability of the hexagonal shaft 9.
[0037] A connector 54 for connecting the hexagonal shaft 9 and the worm 3 is provided between the end of the hexagonal shaft 9 away from the offset reduction motor 51. The connector 54 in this embodiment is configured as a cross universal joint coupling, and the two ends of the cross universal joint coupling are respectively connected to the worm 3 and the hexagonal shaft 9. At the same time, in order to ensure the synchronization of the master and slave ends, the cross universal joint coupling adopts a double-connection type in this application, and the double-connection method can be connected by welding or flanges or bolts. The cross universal joint coupling utilizes the characteristics of its mechanism. Its two shafts are not on the same axis. When there is an axis angle β, the two connected shafts can be rotated continuously and torque and motion can be transmitted reliably.
[0038] The working principle of the embodiment of the present application is as follows: the grinding device is mounted on the mounting plate 4, and then the offset reduction motor 51 is used to drive the driving gear 52 to rotate, thereby rotating the hexagonal hole gear 53 meshing with the driving gear 52, and then rotating the hexagonal shaft 9. The hexagonal shaft 9 can then transmit power to the worm 3 through the connecting member 54. The worm 3 then drives the worm wheel 2 to rotate, thereby causing the mounting plate 4 fixedly connected to the worm wheel 2 to rotate a certain range, thereby changing the grinding angle of the grinding device without stopping the operation of the grinding device.
[0039] Example 2
[0040] The difference from Example 1 is that the mounting plate 4 includes a main plate 41 and a sub-plate 42. The worm gear 2 is fixedly connected to the main plate 41. The sub-plate 42 is used to fix the grinding device. A connecting component 44 is provided between the main plate 41 and the sub-plate 42 for connecting the two.
[0041] The connecting assembly 44 includes a connecting ball 441 located at the center of the main plate 41. A plurality of springs 442 are disposed around the connecting ball 441, with the lengths of the springs 442 perpendicular to the end surface of the main plate 41. In this embodiment, there are six springs 442, equidistantly spaced around the axis of the connecting ball 441. One end of the spring 442 is fixedly connected to the main plate 41, and the other end is fixedly connected to the sub-plate 42.
[0042] An adjustment mechanism 43 for adjusting the angle of the sub-plate 42 is located between the main plate 41 and the sub-plate 42. The adjustment mechanism 43 comprises a top plate 431 fixedly connected to the upper end of the main plate 41. Below the top plate 431 is an adjustment post 432, positioned on one side of the connecting ball 441. The length of the spring 442 gradually decreases from the side closest to the adjustment post 432 to the side further away from the adjustment post 432, thereby causing the end of the sub-plate 42 farther from the adjustment post 432 to deflect toward the main plate 41. The axis of the adjustment post 432 is parallel to the end surface of the main plate 41. Multiple first adjustment cords 433 and multiple second adjustment cords 434 are wound around the adjustment post 432. These cords are equidistantly spaced along the height of the adjustment post 432, with intervals between them.
[0043] A plurality of fixed thread grooves 45 are provided on both the main plate 41 and the auxiliary plate 42 . The fixed thread grooves 45 on the main plate 41 correspond one-to-one to the first adjustment ropes 433 , and the fixed thread grooves 45 on the auxiliary plate 42 correspond one-to-one to the second adjustment ropes 434 .
[0044] The first adjustment cord 433 is an elastic cord with good tensile strength, used to connect the adjustment column 432 and the main board 41. One end of the first adjustment cord 433 is fixedly connected to the adjustment column 432. The other end of the first adjustment cord 433 is provided with a fixing bolt 46, which is threaded into the fixed thread groove 45. The nut portion of the fixing bolt 46 presses the first adjustment cord 433 against the notch of the fixed thread groove 45. Thus, the first adjustment cord 433 is fixedly connected to the main board 41 via the fixing bolt 46.
[0045] The second adjustment rope 434 is a steel rope. One end of the second adjustment rope 434 is fixedly connected to the adjustment column 432. The other end of the second adjustment rope 434 is provided with a fixing bolt 46, which is threaded into the fixing thread groove 45. The nut portion of the fixing bolt 46 presses the second adjustment rope 434 against the notch of the fixing thread groove 45. Thus, the second adjustment rope 434 is fixedly connected to the main board 41 via the fixing bolt 46.
[0046] A rotating motor 435 is fixedly connected to the top plate 431 . The output shaft of the rotating motor 435 is coaxially arranged with the adjustment column 432 . The output shaft of the rotating motor 435 passes through the top plate 431 and is fixedly connected to the upper end of the adjustment column 432 .
[0047] The implementation principle of Example 2 is as follows: by starting the rotary motor 435, the rotary motor 435 rotates, which in turn drives the adjustment column 432 to rotate, causing the first adjustment rope 433 and the second adjustment rope 434 to be wound around the adjustment column 432, thereby changing the length of each spring 442. This changes the distance between the main plate 41 and the auxiliary plate 42 at the adjustment column 432, thereby changing the angle between the main plate 41 and the auxiliary plate 42. At the same time, by changing the fixing position of the first adjustment rope 433 and the second adjustment rope 434 by the fixing bolt 46, the length of the first adjustment rope 433 and the second adjustment rope 434 can be changed, thereby generating an inclination angle in the height direction of the auxiliary plate 42, thereby allowing the auxiliary plate 42 to be adjusted not only left and right but also up and down. This increases the deflection range of the deflection mechanism.
[0048] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
