The connection and crossing equipment set at the required line is the switch. The switch point consists of two basic rails, two switch rails, a switching mechanism and various connecting parts. Its function is to guide the wheels from one line to another line. The switch rail is one of the main components of the switch machine. The train enters the straight or side track of the switch according to the different opening directions of the switch rail. The switch rail is divided into a straight switch rail and a curved switch rail according to the plane form.

[0003] At present, affected by the centripetal force and friction of train operation, the switch rail is prone to be damaged by rolling. The damage of the switch rail mostly occurs at the relatively weak part of the tip section of the switch rail. The main reason is that the burrs on the switch rail are not polished in time, and when the wheel passes through, the burrs and part of the top surface of the switch rail are lifted at the same time. The burr disease of the switch rail will not only cause poor geometric dimensions at the switching part, resulting in the switch shaking, but also cause damage diseases such as peeling and chipping of the switch rail, threatening the safety of train operation and shortening the service life of the switch rail. Therefore, the switch rail part of the switch machine needs to be polished and repaired irregularly.

Specific embodiments

[0021] The following specific embodiments illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all of them. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] With reference to Figures 1 - 4, the present utility model provides a turnout switch machine repair device for grinding and repairing the stock rail 1 of a turnout switch machine. It includes a moving car body 2 which can move along the path of the stock rail 1. The moving car body 2 is movably arranged on the stock rail 1. A linear module 3 is arranged on the moving car body 2. A bracket 4 is arranged at the sliding part of the linear module 3. The linear module 3 can drive the bracket 4 to move horizontally on the moving car body 2. A grinding orientation adjustment structure 5 is arranged on the bracket 4. The grinding orientation adjustment structure 5 includes a self-locking motor 51 fixedly connected to the bracket 4 and a swing arm 52 fixedly connected to the output end of the self-locking motor 51. An encoder can be arranged on the self-locking motor 51, so as to improve the rotation precision of the self-locking motor 51 to meet the use requirements of the precise grinding angle of the stock rail 1. The self-locking motor 51 can meet the driving self-locking property, so as to improve the reliability of the grinding angle adjustment. A grinding feed structure 6 is arranged on the swing arm 52. A grinding mechanism 7 for grinding the stock rail 1 is arranged on the grinding feed structure 6. The grinding feed structure 6 is used to control the grinding mechanism 7 to approach or move away from the stock rail 1.

[0023] A pair of avoidance grooves 8 are formed on the moving car body 2. The grinding mechanism 7 is located in one of the avoidance grooves 8. The length of the linear module 3 is greater than the length of the moving car body 2. The setting of the pair of avoidance grooves 8 enables the grinding mechanism 7 to flexibly move into one of the avoidance grooves 8, so as to facilitate the switching grinding treatment of a pair of parallel stock rails 1. The advantage of the length setting of the linear module 3 is that it can ensure that the grinding mechanism 7 effectively rotates around the outside of the stock rail 1 during angle adjustment to meet the requirements of various grinding angles of the stock rail 1.

[0024] Track wheels 9 are arranged at the bottom corners of the moving car body 2. The track wheels 9 are in rolling connection with the stock rail 1. A handle rod 10 is fixedly connected to the moving car body 2. In this application, the moving car body 2 can be moved by hand-pushing, and in other embodiments, it can also be driven by equipment to realize walking.

[0025] A chute 11 is formed on the side of the bracket 4. One end of the swing arm 52 facing away from the self-locking motor 51 is fixedly connected with a sliding column 12. The sliding column 12 is slidably connected in the chute 11. The setting of the sliding column 12 sliding in the chute 11 can share the supporting force of the swing arm 52 when the self-locking motor 51 drives the swing arm 52 to rotate at an angle, so as to improve the stability of the grinding position of the grinding mechanism 7.

[0026] The grinding feed structure 6 includes a support plate 61 fixedly connected to one end of the swing arm 52, a telescopic device 62 fixedly connected to the support plate 61, and a lifting plate 63 fixedly connected to the output end of the telescopic device 62. A pair of optical rods 13 are fixedly connected to the lifting plate 63, and both of the pair of optical rods 13 slidably penetrate through the support plate 61. The telescopic device 62 can adopt telescopic devices such as hydraulic rods. Under the adjustment requirement of the grinding angle given by the grinding orientation adjustment structure 5 to the grinding feed structure 6, in this way, the grinding mechanism 7 can be correspondingly located on one side of the switch rail 1 at a specific angle, and the grinding feed structure 6 can control the distance between the grinding mechanism 7 and the switch rail 1 to realize the grinding operation of the grinding mechanism 7 approaching or departing from the switch rail 1.

[0027] The grinding mechanism 7 includes a grinding motor 71 fixedly connected to the lifting plate 63 and a grinding wheel 72 fixedly connected to the output end of the grinding motor 71. All the driving devices involved in this application are connected to the power supply and the controller.

[0028] When the present utility model is in use, the moving car plate 2 is placed on a pair of switch rails 1 for movement. At this time, the bracket 4 thereon is moved to the area of one of the avoidance grooves 8 through the linear module 3. Then, the self-locking motor 51 can be controlled to drive through the encoder. The self-locking motor 51 drives the swing arm 52 to perform precise rotation, so that the grinding mechanism 7 precisely corresponds to the movement of the switch rail 1 at a specific angle. In this way, the telescopic device 62 can drive the lifting plate 63 to extend, and the optical rods 13 slidably arranged on the support plate 61 can ensure the balance of the movement of the lifting plate 63. In this way, the lifting plate 63 can drive the grinding wheel 72 on the grinding motor 71 to approach the switch rail 1. The grinding motor 71 drives the grinding wheel 72 to rotate, so that the grinding wheel 72 can grind and repair the excess metal edge of the switch rail 1. In this way, the geometric dimension of the turnout part will not be affected by the excess metal edge disease of the switch rail 1, resulting in turnout bumping, ensuring the safety of train operation and improving the service life of the switch rail 1; because the grinding orientation adjustment structure 5 can precisely control the orientation of the grinding mechanism 7, the requirement of multi-angle grinding of the switch rail 1 can be met.

[0029] In addition, when it is necessary to grind and repair another switch rail 1, when the grinding mechanism 7 transitions to another avoidance groove 8, an angle adjustment is required, and this angle adjustment can be realized through the grinding orientation adjustment structure 5, so as to facilitate position crossing.
