Vehicles such as high-speed trains, motor trains and subways are guided to run by rails, so that the rails bear huge pressure and impact force from wheels. In the running process of a train, a steel rail is under extremely complex and severe working conditions for a long time, and various damages are inevitably generated due to continuous deterioration of rail surface conditions and deformation of a rail head caused by multiple reasons such as power action, natural environment, quality of the steel rail and the like. In addition, damage may occur during the manufacturing, transportation, construction and use of the rails. The common rail damages are mainly as follows: vertical wear, side wear, wave wear, rail face scaling, fat edge flaking, and rail abrasion, among others. The damage damages the optimal outline shape of the steel rail, changes the contact state of the wheel rail, increases the noise of the wheel rail, accelerates the deterioration rate of vehicle parts and track parts, aggravates the further expansion of the steel rail diseases and seriously affects the driving safety.

When the railway main track is polished, the rail leaning device 100 is in a locking state and does not drop to participate in polishing operation. When the turnout area is polished, the rail leaning device 100 is lowered to participate in polishing operation. When polishing the switch, the car of polishing moves outside the interval of polishing to, presses the button of transferring polishing dolly 200, need realize three action: a locking cylinder (an oil cylinder, an electric cylinder and the like can also be adopted for replacing) of the locking device 50 acts, and a locking air hook is retracted; lowering the polishing trolley 200 by releasing the lifting mechanism 80; the traverse mechanism 4 and the vertical movement mechanism 6 of the rail contact device 100 operate to bring the rail contact wheel 8 into close contact with the rail 40.

An embodiment of the working method of the rail leaning device of the grinding trolley comprises the following steps:

s11) the traversing mechanism 4 of the rail contact device 100 is extended to move the flange surface of the rail contact wheel 8 toward the middle position of the two rails 40 so as to stagger the flange surface of the rail contact wheel 8 and the side surfaces of the rails 40;

s12) the vertical movement mechanism 6 of the rail contact device 100 works, the vertical movement mechanism 6 extends out, and the rail contact wheel 8 is pressed down to the top surface of the steel rail 40 by controlling the working pressure of the vertical movement mechanism 6;

s13) releasing the acting force of the transverse moving mechanism 4, enabling the transverse moving mechanism 4 to float and realize the pressing of the side surface of the steel rail 40 by the tension of the first elastic part 9, and feeding back the position state of the transverse moving mechanism 4 (the transverse moving mechanism 4 is provided with a displacement sensor);

s14) the automatic setting of the traverse amount of the traverse mechanism 4 of the grinding unit 20 is realized by calculating the relative change amounts of the initial position of the traverse mechanism 4 and the post-rail travel position and obtaining the traverse amount of the traverse mechanism two 60 in combination with the initial position of the traverse mechanism two 60 of the grinding unit 20, as shown in fig. 8.

The initial traverse amount of the second traverse mechanism 60 of the dressing unit 20 is S0, and when the length of the traverse mechanism 4 is changed to L1-L0, the traverse amount of the second traverse mechanism 60 of the dressing unit 20 is adjusted to S0+ (L1-L0).

When the rail device 100 is lowered, the first elastic component 9 is used for tensioning to provide lateral pressure rail force, and the vertical moving mechanism 6 provides vertical downward force. When the rail leaning device 100 does not need to perform rail leaning operation, the second elastic component 10 is tensioned and pulls the rail leaning wheel 8 away from the rail surface of the rail 40.
