[0077] The following will be combined with the attached Figure 1 To Attachment Fig.14 The present invention is further described.

[0078] It should be noted that Figure 1 The direction parallel to the X-axis is the length direction of the vehicle body 1, which is also the length direction of the straight strand 100.

[0079] The embodiment of the present invention provides a continuous track-raising device for a switch area, which includes a vehicle body 1, and a curved track-raising device 4 and two straight track-raising devices arranged on the vehicle body 1.

[0080] like Figure 1 , Figure 2 and Fig.13 As shown, during the continuous track lifting process of the turnout area, the car body 1 moves forward along the length direction of the straight strand 100.

[0081] Two straight strand track-lifting devices are arranged at intervals and are respectively reciprocatably arranged on the vehicle body 1. The straight strand track-lifting devices can lift the straight strand 100 by clamping and lifting it. When one of the two straight strand track-lifting devices lifts the straight strand 100, the straight strand track-lifting device remains relatively still with the straight strand 100 along the length direction of the straight strand 100, and the other straight strand track-lifting device moves forward a preset length along the length direction of the straight strand 100 to lift the next position on the straight strand 100. The two straight strand track-lifting devices can lift and release the straight strand 100 alternately in turn, thereby cooperatively realizing alternating and continuous lifting of the straight strand 100.

[0082] The curved track lifting device 4 is used to lift the curved track 200 in the turnout area.

[0083] In this embodiment, two straight strand track-lifting devices are arranged at intervals on the car body 1. The two straight strand track-lifting devices can reciprocate relative to the car body 1 on the car body 1. With the movement of the car body 1, the straight strand track-lifting devices can remain stationary or move forward relative to the straight strand 100 along the length direction of the straight strand 100; the two straight strand track-lifting devices can cooperate to realize alternating and continuous track-lifting of the straight strand 100 by alternately lifting and releasing the straight strand 100 in sequence, thereby ensuring continuity and indirectly improving the efficiency and effect of excavation and backfilling operations. At the same time, the curved strand track-lifting device 4 can lift the curved strand 200. Therefore, the continuous track-lifting equipment in the turnout area in this embodiment can realize continuous track-lifting in the turnout area, meet the track-lifting operation requirements for complex tracks in the turnout area, and backfilling after track-lifting is convenient and the effect is ideal. There is no need to dismantle the equipment during the track-lifting process, and it is easy to use.

[0084] The two straight track-raising devices are arranged at intervals along the length direction of the vehicle body 1 , and are respectively arranged on the vehicle body 1 so as to be reciprocally movable along the length direction of the vehicle body 1 .

[0085] One of the two straight strand track-raising devices is a first straight strand track-raising device 2 , and the other is a second straight strand track-raising device 3 .

[0086] ① The first straight strand track-lifting device 2 is introduced as follows:

[0087] like Figures 3 to 8 As shown, the first straight strand track raising device 2 comprises a first clamping device 21 and a first driving transmission device which are connected to each other.

[0088] The first clamping device 21 is used to clamp or release two straight strands 100. Specifically, the first clamping device 21 includes two first clamping mechanisms 211 and a first mounting beam 212 for mounting the two first clamping mechanisms 211. The two first clamping mechanisms 211 correspond to the two straight strands 100 one by one and are respectively used to clamp the corresponding straight strands 100. The first mounting beam 212 is arranged horizontally, and the two first clamping mechanisms 211 are arranged at both ends of the first mounting beam 212.

[0089] By driving the first mounting beam 212 to move, the two first clamping mechanisms 211 thereon can be driven to move simultaneously, so that the two first clamping mechanisms 211 can be adjusted to appropriate positions at the same time, and the coordination of the two first clamping mechanisms 211 can be improved.

[0090] The length of the first mounting beam 212 matches the distance between the two straight strands 100 .

[0091] The first clamping mechanism 211 includes two first clamping parts 2111 arranged opposite to each other, and the two first clamping parts 2111 can clamp or release by moving closer to or farther from each other. The first clamping part 2111 can be a clamping hook or a clamping plate.

[0092] The first driving transmission device is drivingly connected to the first clamping device 21 and is used to drive the first clamping device 21 to move along the X, Y and Z directions, and to rotate around the rotation axis 2521 along the Z axis.

[0093] The first driving transmission device in this embodiment includes a first longitudinal movement mechanism 22, a first lifting mechanism 23, a rotating mechanism 25, and a first transverse movement mechanism 24 which are connected in sequence. The first longitudinal movement mechanism 22 is arranged on the vehicle body 1 so as to be reciprocatingly movable along the length direction of the vehicle body 1, and the first transverse movement mechanism 24 is connected to the first clamping device 21. The first longitudinal movement mechanism 22, the first lifting mechanism 23, and the first transverse movement mechanism 24 are respectively used to drive the first clamping device 21 to move along the X, Z, and Y directions. The details are as follows:

[0094] First longitudinal movement mechanism 22: The first longitudinal movement mechanism 22 includes a first supporting frame 221 and a first driving mechanism drivingly connected thereto.

[0095] The first support frame 221 can be reciprocatingly arranged on the vehicle body 1 along the length direction of the vehicle body 1, and the first lifting mechanism 23 is installed on the first support frame 221. The first support frame 221 can move along the length direction of the vehicle body 1 under the drive of the first driving mechanism to drive the first lifting mechanism 23 to move along the length direction of the vehicle body 1, thereby indirectly driving the first clamping device 21 to move along the X direction during the track lifting process.

[0096] The vehicle body 1 is provided with two first guide rails 11 which are parallel to each other and extend along the length direction of the vehicle body 1, and the first support frame 221 is mounted on the first guide rails 11. In this way, the first guide rails 11 provide guidance for the reciprocating movement of the first support frame 221 along the length direction of the vehicle body 1.

[0097] Rollers 5 for cooperating with the first guide rail 11 are arranged on opposite sides of the first support frame 221, and the first support frame 221 moves back and forth on the first support frame 221 through the rollers 5 on both sides. In this way, the first support frame 221 is provided with rollers 5 for rolling cooperation with the first guide rail 11, which can reduce the friction resistance when the first support frame 221 moves, so that the first support frame 221 moves more steadily and smoothly along the first guide rail 11.

[0098] The cross section of the first guide rail 11 is U-shaped, the U-shaped openings of the two first guide rails 11 are opposite to each other, the first support frame 221 is clamped between the two first guide rails 11, and the rollers 5 on the first support frame 221 are embedded in the inner cavity of the U-shaped first guide rail 11 and rollingly cooperate with the inner wall.

[0099] As an implementation method, Figure 6 to Figure 7 As shown, the first driving mechanism includes a driving block 222, a driving gear 223 and a transmission rack 224. It should be noted that: Figure 6 The direction of the middle arrow is the reciprocating direction of the first supporting frame 221 along the length direction of the first guide rail 11 .

[0100] The transmission rack 224 is fixedly mounted on the first guide rail 11 along the length direction of the first guide rail 11, the driving gear 223 is meshed with the transmission rack 224 for transmission, the driving gear 223 is rotatably mounted on the driving block 222, the driving block 222 is mounted on the first support frame 221, and the driving gear 223 is drivingly connected to the power component. The driving gear 223 is suitable for rotating under the drive of the power component and moving along the length direction of the rack to drive the driving block 222 and the first support frame 221 to move along the length direction of the straight strand 100, thereby indirectly driving the first clamping device 21 to move along the X direction.

[0101] As another embodiment, the first driving mechanism includes a hand wheel and a lead screw, which are not shown in the figure.

[0102] The lead screw extends along the length direction of the first guide rail 11, one end of the lead screw passes through the first support frame 221 and is transmission-connected to the first support frame 221, and the other end of the lead screw is connected to the hand wheel. The lead screw is rotated by turning the hand wheel, thereby driving the first support frame 221 to move along the length direction of the lead screw, that is, along the length direction of the first guide rail 11.

[0103] As other implementations, the first driving mechanism can also be a driving structure such as a sprocket chain drive, a motor directly driving the roller 5, a cylinder drive, a pneumatic cylinder drive, an electric cylinder drive, etc., which will not be repeated here.

[0104] The first lifting mechanism 23: Figures 3 to 5 As shown, the first lifting mechanism 23 is a cylinder driving mechanism.

[0105] The cylinder driving mechanism includes a cylinder fixedly mounted on the first supporting frame 221 and a telescopic rod drivingly connected to the cylinder. The telescopic rod extends along the Z axis. The cylinder telescopic mechanism can telescope along the Z axis through the telescopic rod, thereby driving the first clamping device 21 to move up and down along the Z axis.

[0106] Preferably, two first lifting mechanisms 23 are provided, and the two first lifting mechanisms 23 are separately provided along the width direction of the vehicle body 1. The two first lifting mechanisms 23 are respectively provided with a first pressure sensor and a first displacement sensor.

[0107] Of course, the first lifting mechanism 23 can also be a driving structure such as a sprocket chain drive, a motor directly driving the roller 5, a cylinder drive, a pneumatic cylinder drive, an electric cylinder drive, etc., which will not be repeated here.

[0108] The first transverse movement mechanism 24: Figures 3 to 5 , and Figure 8 As shown, the first transverse movement mechanism 24 is also a cylinder drive mechanism. The first transverse movement mechanism 24 also includes a cylinder and a telescopic rod driven by the cylinder. The telescopic rod extends along the X-axis. The cylinder telescopic mechanism can move along the X-axis through the telescopic rod, thereby driving the first clamping device 21 to move along the X-axis to adjust the first clamping device 21 to a position suitable for clamping.

[0109] It should be noted that Figure 8 The direction of the middle arrow indicates the moving direction of the first clamping device 21 relative to the first transverse movement mechanism 24 .

[0110] The rotating mechanism 25 is used to drive the first clamping device 21 to rotate. Figures 3 to 5 As shown, since the first straight strand track-raising device 2 is located in the blade and slope excavation area, the first clamping device 21 is rotated and retracted by the rotating mechanism 25 to avoid interference between the first clamping device 21 and the blade and slope excavation.

[0111] The rotating mechanism 25 has a rotating shaft 2521 extending along the Z axis. The rotating mechanism 25 is used to drive the first clamping device 21 to rotate around the rotating shaft 2521. During the rotation of the first clamping device 21, the first mounting beam 212 can reach a working position extending along the Y axis and a stowed position extending along the X axis.

[0112] When the two straight strands 100 are raised, the first mounting beam 212 is adjusted to a working position extending along the Y axis. At this time, the two first clamping mechanisms 211 at both ends of the first mounting beam 212 are also arranged along the width direction of the straight strand 100 to facilitate raising the strand.

[0113] After the track raising operation is completed, the first mounting beam 212 is adjusted to a stowed position extending along the X-axis. At this time, the first mounting beam 212 is consistent with the length direction of the vehicle body 1.

[0114] Preferably, the rotating shaft 2521 is arranged colinearly with the symmetry center lines of the two first clamping mechanisms 211 .

[0115] Optionally, the rotating mechanism 25 is connected between the first lifting mechanism 23 and the first transverse movement mechanism 24 .

[0116] The rotating mechanism 25 includes a fixed mounting member 251 and a rotating member 252 which are rotatably connected.

[0117] The fixed mounting member 251 is fixedly connected to the first lifting mechanism 23 , the rotating member 252 is fixedly connected to the first transverse movement mechanism 24 , the rotating member 252 has a rotating shaft 2521 extending along the Z-axis direction, and the rotating member 252 can be rotatably connected to the fixed mounting member 251 around the rotating shaft 2521 .

[0118] Preferably, internal teeth are provided on the inner circumferential wall of the fixed mounting member 251, and external teeth are correspondingly provided on the outer circumferential wall of the rotating member 252. The fixed mounting member 251 and the rotating member 252 are transmitted through the meshing of the internal teeth and the external teeth. The internal teeth and the external teeth are coaxially arranged, and the rotating shaft 2521 of the rotating member 252 is the axis of the internal teeth.

[0119] The rotating member 252 is drivingly connected to the output end of the power component, and the power component may be a driving motor.

[0120] In this embodiment, the rotating member 252 is driven by the power component to rotate relative to the fixed mounting member 251 around the rotating shaft 2521 to drive the first transverse movement mechanism 24 and the first clamping device 21 to rotate around the rotating shaft 2521 .

[0121] Of course, the connection sequence among the first longitudinal movement mechanism 22, the first lifting mechanism 23, the rotating mechanism 25, and the first transverse movement mechanism 24 can be adjusted according to actual conditions.

[0122] like Figure 1 As shown, the first straight strand track-raising device 2 also includes a first rolling wheel 26 suitable for stopping on the straight strand 100 and rolling forward along the straight strand 100. The first rolling wheel 26 can be lifted and lowered along with the first lifting mechanism 23. During the track-raising operation, the first rolling wheel 26 presses against the straight strand 100 to ensure that the first straight strand track-raising device 2 can smoothly reciprocate along the first guide rail 11, and at the same time can ensure that the first straight strand track-raising device 2 can move with the vehicle on the straight strand 100.

[0123] Optionally, the first rolling wheel 26 is mounted on the first clamping device 21 .

[0124] ② The second straight strand track raising device 3 is introduced as follows:

[0125] like Fig. 9 and Fig.10 As shown, the second straight strand track device 3 is substantially the same as the first straight strand track device 2, except that the second straight strand track device 3 may not be provided with a rotating mechanism 25. The second straight strand track device 3 comprises a second longitudinal movement mechanism 32, a second lifting mechanism 33, a second transverse movement mechanism 34, and a second clamping device 31.

[0126] As an embodiment, the second longitudinal movement mechanism 32 , the second lifting mechanism 33 , the second transverse movement mechanism 34 , and the second clamping device 31 are respectively the same in structure as the first longitudinal movement mechanism 22 , the first lifting mechanism 23 , the first transverse movement mechanism 24 , and the first clamping device 21 .

[0127] Other variant implementations are as follows:

[0128] The second longitudinal movement mechanism 32 includes a second support frame 321 and a second driving mechanism 322 drivingly connected thereto. The vehicle body 1 is provided with two second guide rails 12 which are parallel to each other and extend along the length direction of the vehicle body 1 , and the second support frame 321 is mounted on the second guide rails 12 .

[0129] The second support frame 321 is provided with a roller 5 for cooperating with the second guide rail 12. The cross-section of the second guide rail 12 is U-shaped. The U-shaped openings of the two second guide rails 12 are away from each other and face outward respectively. The two second guide rails 12 are clamped in the second support frame 321. The rollers 5 on the second support frame 321 are all embedded in the inner cavity of the U-shaped first guide rail 11 and roll with the inner wall.

[0130] The second lifting mechanism 33 is fixedly mounted on the second support frame, and two second lifting mechanisms 33 are provided, and the two second lifting mechanisms 33 are separated and arranged along the width direction of the vehicle body 1. The two second lifting mechanisms 33 are respectively provided with a second pressure sensor and a second displacement sensor.

[0131] The second clamping device 31 includes two second clamping mechanisms 312 and a second mounting beam 311 for mounting the two second clamping mechanisms 312. The structure of the second clamping mechanism 312 is substantially the same as that of the first clamping mechanism 211. Rail guard covers 313 are also provided at both ends of the second mounting beam 311. The rail guard covers 313 extend along the length direction of the straight strands 100 and are used to cover the two straight strands 100. The provision of the rail guard covers 313 can effectively prevent foreign objects such as ballast from entering areas such as the point rail and the guard rail, effectively reducing the difficulty of cleaning after the track is lifted, saving time and effort.

[0132] Preferably, the second clamping mechanism 312 includes two second clamping parts, and the guardrail cover 313 is located between the two second clamping parts.

[0133] Of course, the first longitudinal movement mechanism 22 and the second longitudinal movement mechanism 32 can be replaced with each other; the first lifting mechanism 23 and the second lifting mechanism 33 can be replaced with each other; the first transverse movement mechanism 24 and the second transverse movement mechanism 34 can be replaced with each other.

[0134] The second straight strand track-raising device 3 also includes a second rolling wheel 35 suitable for stopping on the straight strand 100 and rolling forward along the straight strand 100. The second rolling wheel 35 can be lifted and lowered along with the second lifting mechanism 33. During the track-raising operation, the second rolling wheel 35 presses against the straight strand 100 to ensure that the second straight strand track-raising device 3 can smoothly reciprocate along the second guide rail 12, and at the same time can ensure that the second straight strand track-raising device 3 can move with the vehicle on the straight strand 100.

[0135] Optionally, the second rolling wheel 35 is mounted on the second clamping device 31 .

[0136] ③ The introduction of the curved track lifting device 4 is as follows:

[0137] like Figure 2 , Fig.11 and Fig.12 As shown, two curved strand raising devices 4 are provided, and the two curved strand raising devices 4 correspond one to one to the two forked curved strands 200, and are used to raise the two curved strands 200 respectively.

[0138] One of the two curved track lifting devices 4 is used to lift a curved track 200 in the switch area, such as the left curved track 200, and the other curved track lifting device 4 is used to lift another curved track 200 in the switch area, such as the right curved track 200.

[0139] Preferably, the two curved track-lifting devices 4 are symmetrically arranged along the left-right symmetrical center line of the vehicle body 1 .

[0140] The two curved track-lifting devices 4 have the same structure, and both include a lifting mechanism 41 , a transverse telescopic mechanism 42 and a third clamping mechanism 43 which are connected in sequence.

[0141] The lifting mechanism 41 is a cylinder telescopic rod mechanism, which includes a cylinder fixedly mounted on the vehicle body 1, and a telescopic rod with one end connected to the cylinder for telescopic driving, and the other end of the telescopic rod is connected to the transverse telescopic mechanism 42 for driving. The lifting mechanism 41 is used to lift the transverse telescopic mechanism 42 upward, thereby lifting the third clamping mechanism 43 arranged on the transverse telescopic rod. The lifting mechanism 41 is also provided with a third pressure sensor.

[0142] The lateral telescopic mechanism 42 includes a lifting rod 421 and a telescopic arm 422 telescopically connected to the lifting rod 421 at one end. The lifting rod 421 is hinged to the telescopic rod in the lifting mechanism 41, and the other end of the telescopic arm 422 is installed with a third clamping mechanism 43.

[0143] The lateral telescopic mechanism 42 can adjust the telescopic amount of the telescopic arm 422 relative to the track-lifting rod 421 according to the lateral spacing from the curved strand 200 to the straight strand 100, thereby adjusting the third clamping mechanism 43 to a suitable position to clamp and lift a curved strand 200 in the switch area.

[0144] The curved strand track raising device 4 further comprises a third rolling wheel 44 which is adapted to stop on the curved strand 200 and can roll forward along the curved strand 200 .

[0145] The switch area continuous track lifting device in this embodiment also includes a controller, and the pressure sensor and displacement sensor on the track lifting device are electrically connected to the controller; each power component on the track lifting device is electrically connected to the controller. The controller can receive the track lifting force and lifting position signal of the track lifting device, and can control the start and stop and speed regulation of the power component to drive the start and stop of the clamping device, longitudinal movement mechanism, lifting mechanism, rotating mechanism 25, transverse movement mechanism, telescopic arm 422 and other components.

[0146] The continuous track lifting equipment in the turnout area can be a cleaning and screening vehicle, or it can be used in conjunction with a cleaning and screening vehicle.

[0147] like Figure 1 , Figure 2 and Fig.13 As shown, an embodiment of the present invention provides a method for continuous track starting in a turnout area, and the method comprises the following steps:

[0148] S1: driving the car body 1 into the initial working position of the turnout area so that the length direction of the car body 1 is consistent with the length direction of the straight strand 100;

[0149] S2: Continuously raise the straight strand 100 and the curved strand 200. Step S2 includes the following steps:

[0150] S21: The two straight strand track-lifting devices located on the vehicle body 1 sequentially and alternately lift and release the straight strand 100 to cooperate in alternately and continuously lifting the straight strand 100; when one of the two straight strand track-lifting devices clamps and lifts the straight strand 100 to lift the straight strand 100, the straight strand track-lifting device and the straight strand 100 are kept relatively stationary along the length direction of the straight strand 100, and the other straight strand track-lifting device moves forward by a preset length along the length direction of the straight strand 100 to lift the next position on the straight strand 100;

[0151] S22: In the process of alternately and continuously raising the straight strands 100, the curved strand raising device 4 is used to raise the curved strand 200.

[0152] Optionally, step S21 includes the following steps:

[0153] S211: The first straight strand track-raising device 2 clamps and lifts the two straight strands 100 to perform track-raising;

[0154] S212: Keep the first straight strand track-raising device 2 stationary relative to the straight strand 100 along the length direction of the straight strand 100, so as to keep the track-raising position of the straight strand 100 unchanged;

[0155] The second straight strand raising device 3 moves forward along the length direction of the straight strand 100 until the distance between the second straight strand raising device 3 and the first straight strand raising device 2 is L1, and then the first straight strand raising device 2 releases the straight strand 100, and the second straight strand raising device 3 clamps and lifts the straight strand 100 to raise the strand;

[0156] S213: Keeping the second straight strand raising device 3 stationary relative to the straight strand 100 along the length direction of the straight strand 100, so as to keep the straight strand 100 in a lifting state;

[0157] After the first straight strand 101 track-raising device 2 moves forward L2 relative to the straight strand 100 along the length direction of the straight strand 100, the second straight strand track-raising device 3 releases the straight strand 100, and the first straight strand track-raising device 2 clamps and lifts the straight strand 100 to perform track-raising;

[0158] S214: Continue to execute steps S212 and S213 in sequence, so as to perform alternating and continuous track-building on the straight strands 100. Specific embodiments

[0160] In this embodiment, the method for continuously raising the track using the turnout area continuous track raising device comprises the following steps:

[0161] Step S1: Drive the car body 1 of the continuous track-lifting equipment in the turnout area into the turnout area. When the car body 1 reaches the initial working position where the track needs to be lifted, make the length direction of the car body 1 consistent with the length direction of the straight strand 100, and lower the first straight strand track-lifting device 2, the second straight strand track-lifting device 3 and the curved strand track-lifting device 4.

[0162] Step S2: The vehicle body 1 is moved along the extending direction of the straight strand 100 to continuously start the track in the turnout area.

[0163] Step S21: The straight strands 100 are alternately and continuously raised.

[0164] Step S22: When the vehicle body 1 drives the curved track lifting device 4 to enter the long switch sleeper of the curved track 200, the curved track 200 is lifted while executing step S21.

[0165] like Fig.13 As shown, step S21 includes the following steps:

[0166] Step ①: The first straight strand raising device 2 clamps two straight strands 100 respectively through two first clamping mechanisms 211, and the first lifting mechanism 23 drives the first lifting mechanism 23 to move upward along the Z axis to raise the straight strand 100;

[0167] Step ②: the vehicle body 1 moves forward along the length direction of the straight strand 100 at a speed of v1, and at the same time, the first straight strand track-raising device 2 moves backward along the first guide rail 11 on the vehicle body 1 at a relative speed of v1 relative to the vehicle body 1, so that the first straight strand track-raising device 2 remains relatively stationary with the straight strand 100 along the length direction of the straight strand 100;

[0168] When the first straight strand track-raising device 2 moves to the end of the first guide rail 11, the vehicle body 1 stops moving forward. At this time, the second straight strand track-raising device 3 is driven by the vehicle body 1 to move to a distance L1 from the first straight strand track-raising device 2, and the first straight strand track-raising device 2 releases two straight strands 100.

[0169] Step ③: The second straight strand raising device 3 clamps and lifts the two straight strands 100 to raise the strands;

[0170] At the same time, the first straight strand track raising device 2 moves on the first guide rail 11 to the head end of the first guide rail 11 .

[0171] It should be noted that, assuming that the length of the first guide rail 11 is a, the forward movement length of the first straight strand track raising device 2 along the straight strand 100 is a.

[0172] Step ④: the vehicle body 1 moves forward along the length direction of the straight strand 100 at a speed of v2, and at the same time, the second straight strand track-raising device 3 moves backward along the second guide rail 12 on the vehicle body 1 at a relative speed of v2 relative to the vehicle body 1, so that the second straight strand track-raising device 3 remains relatively stationary with the straight strand 100 along the length direction of the straight strand 100;

[0173] When the second straight strand track-lifting device 3 moves to the end of the second guide rail 12 , the vehicle body 1 stops moving forward, and the second straight strand track-lifting device 3 releases the straight strand 100 .

[0174] It should be noted that, assuming that the length of the second guide rail 12 is b, in step ④, the length of the first straight strand track raising device 2 moving forward along the straight strand 100 driven by the vehicle body 1 is b. v1 and v2 may be equal or different.

[0175] Step ⑤: The first straight strand raising device 2 raises the two straight strands 100 ; at the same time, the second straight strand raising device 3 moves on the second guide rail 12 to the head end of the second guide rail 12 .

[0176] Continue to perform steps ② to ⑤ and enter the next cycle, thereby achieving continuous starting of the straight strand 100.

[0177] Combination Figure 1 and Figure 2 , step S22 comprises the following steps:

[0178] Step S221: According to the position of the curved strand 200 relative to the vehicle body 1, the curved strand raising device 4 is reasonably selected.

[0179] Step S222: adjusting the telescopic amount of the telescopic arm 422 in the curved strand track-lifting device 4 relative to the track-lifting rod 421, adjusting the position of the third clamping mechanism 43, and clamping the curved strand 200 by the third clamping mechanism 43;

[0180] Step S223: Using the lifting mechanism 41 to lift the curved strand 200 .

[0181] The length of ordinary rail is 2.6m, while the straight strand 100 and the curved strand 200 in the turnout area usually use the same sleeper 300. The sleeper 300 at this position is longer, and the longest sleeper 300 is about 4.7m long. Since the gravity of the track row and the track-lifting resistance torque are relatively large at this location, it is necessary to use a straight strand track-lifting device to apply a counter-track-lifting force to the straight strand to eliminate the side tilt of the sleeper 300 and improve the track-lifting condition, and then the curved strand track is lifted by the curved strand track-lifting device 4.

[0182] Step S223 includes the following steps:

[0183] Step S2231: the lifting mechanism 41 lifts the curved strand 200, and the third pressure sensor and the third position sensor on the lifting mechanism 41 transmit the lifting force signal and the displacement signal of the curved strand 200 to the controller respectively;

[0184] At the same time, the first pressure sensor on the first lifting mechanism 23 and the second pressure sensor on the second lifting mechanism 33 transmit lifting force signals to the controller respectively;

[0185] The first position sensor on the first lifting mechanism 23 and the second position sensor on the second lifting mechanism 33 transmit displacement signals to the controller respectively;

[0186] The controller receives the above signal.

[0187] Step S2232: The controller determines whether the sleeper 300 in the turnout area has a tendency to tilt toward the curved strand 200 based on the difference in displacement between the first straight strand 101 and the second straight strand 102. If so, step S2233 is executed.

[0188] It should be noted that when the switch area sleeper 300 has a tendency to tilt toward the curved strand 200, if no measures are taken, the curved strand track-lifting device 4 is not sufficient to lift the curved strand 200.

[0189] In step 3233, the controller controls the first lifting mechanism 41 or the second lifting mechanism 41 so that the first clamping mechanism 211 or the second clamping mechanism 312 applies downward pressure to the straight strand 100 farthest from the curved strand 200 among the two straight strands 100 until the inclination of the sleeper 300 is eliminated, thereby lifting the curved strand 200.

[0190] Specifically, take the two straight strands 100 located on the left side of the curved strand 200 as an example for explanation:

[0191] like Fig.14 As shown, along the width of the sleeper 300 , from left to right there are the first straight strand 101 , the second straight strand 102 , the first curved strand 201 , and the second curved strand 202 .

[0192] Since the sleeper 300 in the turnout area is relatively long, after the first straight strand 101 and the second straight strand 102 are lifted, the rail weight and the lifting resistance torque are relatively large, and the lifting force in the first curved strand 201 and the second curved strand 202 is insufficient, so the sleeper 300 tilts toward the first curved strand 201 and the second curved strand 202. Since the left side of the sleeper 300 is tilted, the displacement sensors installed on the left and right lifting cylinders respectively measure the lifting amount of the two positions, and the controller determines whether the sleeper 300 is tilted. When it is determined that the tilt occurs, the controller controls the first lifting mechanism 23 or the second lifting mechanism 33 relative to the first straight strand 101 to descend, so that the first clamping mechanism 211 or the second clamping mechanism 312 applies downward pressure to the first straight strand 101 until the tilt of the sleeper 300 is eliminated, so that the curved strand 200 can be lifted.

[0193] In this way, the sleeper 300 can be prevented from tilting and the track starting condition can be improved.

[0194] Similarly, when two straight strands 100 are located on the right side of the curved strand 200, downward pressure can be applied to the rightmost straight strand 100 of the sleeper 300 to eliminate the tilt of the sleeper 300 and improve the track start condition.

[0195] Finally, after the continuous track-lifting operation is completed, the first straight track-lifting device 2, the second straight track-lifting device 3 and the curved track-lifting device 4 are lifted, and the car body 1 drives the track-lifting devices to leave the turnout area.

[0196] Although the present invention has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced by equivalents without departing from the scope of the present invention. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
