The control component can match the left track lifting force and the right track lifting force according to the actual use requirements by controlling the first lifting cylinder and the second lifting cylinder;

[0047] By controlling the third lifting cylinder, the third rail lifting force can be matched according to actual use requirements;

[0048] Preferably, the main track-raising assembly, the auxiliary track-raising assembly and the third track-raising assembly are arranged on the working vehicle frame in no particular order along the straight track laying direction, for example, the main track-raising assembly, the third track-raising assembly and the auxiliary track-raising assembly are arranged in sequence along the straight track laying direction; the main track-raising assembly, the auxiliary track-raising assembly and the third track-raising assembly can also be arranged in sequence along the straight track laying direction; the third track-raising assembly, the main track-raising assembly and the auxiliary track-raising assembly can also be arranged in sequence along the straight track laying direction;

[0049] Preferably, in step 3, the working vehicle moves along the direction in which the straight track extends, and at the same time, the track-lifting device continuously lifts the turnout area, specifically including:

[0050] Step 31: The main track-lifting assembly and the auxiliary track-lifting assembly alternately lift the straight track continuously.

[0051] More preferably, in the step, the main track-raising assembly and the auxiliary track-raising assembly alternately raise the straight track continuously, which specifically includes the following steps:

[0052] Step 311: two first clamping components provided on the main track lifting assembly clamp the two rails of the straight track respectively, and then the first lifting cylinder provided on the main track lifting assembly performs a track lifting operation on the two rails of the straight track;

[0053] Step 312: When the main track-lifting assembly slides on the two first longitudinal tracks to the ends of the two first longitudinal tracks, the main track-lifting assembly releases the two steel rails of the straight track;

[0054] Step 313: The two second clamping components provided on the auxiliary track lifting assembly clamp the two rails of the straight track respectively, and then the second lifting cylinder provided on the auxiliary track lifting assembly performs a track lifting operation on the two rails of the straight track, and at the same time, the main track lifting assembly slides on the two first longitudinal tracks to the head ends of the two first longitudinal tracks;

[0058] Secondly, after one of the components is clamped, due to the large friction between the clamping component and the rail, it can no longer move with the whole vehicle (fixed in the clamping position). Only the track fixed on the frame moves with the whole vehicle. When the clamping component reaches the end of the track relatively quickly, the clamping must be cancelled and quickly returned to the head end, otherwise the clamping component will be damaged. This is equivalent to the whole vehicle and the track moving forward after clamping, and the clamping component is fixed. After the whole vehicle travels a certain distance, if the clamping component is at the end, it will directly fall off the track and be damaged.

[0059] Then the process returns to step 312 and enters the next cycle.

[0062] Preferably, in step 3, the working vehicle moves along the direction in which the straight track extends, and at the same time, the track-lifting device continuously lifts the turnout area, further comprising:

[0063] Step 32: When the working vehicle drives the third rail track-lifting assembly to move away from the switch area and enter the curved track, the third rail track-lifting assembly lifts the curved track until the third rail track-lifting assembly moves to the longest sleeper.

[0064] More preferably, in step 32, the third track raising assembly raises the curved track, specifically comprising:

[0065] Step 321: selecting a third track starting component according to the position of the curved track;

[0066] Step 322: After the telescopic arm is extended, the third clamping component clamps the steel rail of the curved track;

[0067] Step 323: Lifting the rails of the curved track by using the third lifting cylinder.

[0068] More preferably, in step 323, the rail of the curved track is lifted by the third lifting cylinder, which specifically includes:

[0069] Step 3231: the third lifting cylinder generates an upward third rail lifting force on the steel rail of the curved track; the third rail lifting force sensor transmits the sensed third rail lifting force signal to the control component;

[0070] At the same time, the left-hand force sensor transmits the sensed left-hand force signal to the control component, and the right-hand force sensor transmits the sensed right-hand force signal to the control component;

[0071] Step 3232: The control component receives a left track starting force signal, a right track starting force signal, and a third track starting force signal;

[0072] Step 3233: determine whether the third rail lifting force is insufficient to lift the curved track, that is, whether the sleepers in the turnout area are inclined toward the curved track. If so, execute step 3234; otherwise, directly execute step 4;

[0073] Step 3234: the control component transmits a back pressure signal opposite to the left track force to the first left track clamping component or the second left track clamping component;

[0074] Step 3235: The first left rail clamping component or the second left rail clamping component (both can generate anti-left track starting pressure upon receiving the back pressure signal) generates anti-left track starting pressure upon receiving the back pressure signal, thereby lifting the curved track and achieving the curved track starting.

[0075] Compared with the prior art, the advantages of the present invention are that it can meet the use requirements of complex structures in the turnout area and realize continuous track lifting. During the track lifting process, there is no need to remove the track lifting device for operation. The operation is simple and easy to use. A large amount of manpower is not required for track lifting, and the quality and efficiency of track lifting operations can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0116] In the present application, the main track-lifting assembly 20 moves longitudinally on the first longitudinal track 101, and the auxiliary track-lifting assembly 30 moves longitudinally on the second longitudinal track 102. The coordinated use of the main track-lifting assembly 20 and the auxiliary track-lifting assembly 30 can realize the alternating track-lifting operation, thereby continuously lifting the straight track in the turnout area.

[0117] Specifically, the working vehicle 10 may be a cleaning vehicle, a tamping vehicle or the like.

[0118] Specifically, the main track raising assembly 20, the auxiliary track raising assembly 30 and the third track raising assembly 40 are arranged on the frame of the working vehicle 10 in no particular order along the straight track laying direction.
