TECHNICAL FIELD

BACKGROUND

[0002] Currently, domestic turnout screen cleaning machines only have CQS-550 turnout screen cleaning machines and CQS-300 side cutting screen cleaning machines produced by iron construction equipment for turnout screen cleaning, but neither of them is designed with a track lifting device.

[0003] The GO4S-III-C type side cutting bucket wheel slope and turnout integrated screen cleaning machine produced by the American HARSCO company and the domestic introduced American KERSHAW company and LORAM company's slope screen cleaning machine all adopt the bucket wheel lifting type of excavation method, and none of them has the function of lifting tracks in the turnout area, and the operation effect is not too good. The turnout screen cleaning machine URM700 produced by the Prace company integrates the track lifting device for the main line and the turnout, and can complete the track lifting operation in the turnout area, with high field operation efficiency.

[0004] The Chinese patent application with publication number CN1317611A provides a tamping vehicle, which belongs to the machinery for regulating the track. The tamping vehicle has a track lifting device at the front of the tamping machine group between the track running mechanisms, which is used to adjust the height by using a driving device, for leveling and aligning the main line formed by the track running mechanisms. The tamping vehicle is also equipped with an auxiliary track lifting device for lifting the turnout branch line branched from the main line, and the track lifting device and the auxiliary track lifting device are equipped with a common measurement system for lifting the turnout in a controlled manner. The common measurement system is composed of a signal transmitter in contact with the main line, which emits a reference line in the form of a light beam parallel to the track plane, and a signal receiver in contact with the branch line, which records the reference line.

[0005] The Chinese patent CN1401851A discloses a machine for track maintenance. The machine comprises a frame supported on a track running mechanism and equipped with a track lifting unit. The track lifting unit is equipped with a track lifting frame which is height-adjustable by means of a track lifting drive and is connected to the frame. The track lifting frame is equipped with two disc pairs of track lifting discs for each track of the track, which are arranged at a distance from each other in the longitudinal direction of the track. The track lifting discs are opened and closed relative to each other in the transverse direction of the track by means of a transverse adjustment drive. The track lifting frame is also equipped with flanged rollers which can roll on the tread of the track. Each disc pair of track lifting discs can be independently adjusted in height relative to the track lifting frame by means of a height adjustment drive. The height adjustment drive is automatically activated in conjunction with the opening of the two track lifting discs which are arranged next to each other in the transverse direction of the track, in order to lower the two track lifting discs relative to the track lifting frame.

[0006] The Chinese patent CN88101033A discloses a walking type tamping and track lifting machine which is particularly suitable for use in switch and crossing areas. The walking track maintenance machine comprises a device for lifting and shifting the tracks in switch and crossing areas and a working frame which runs on the tracks by means of flanged wheels. The frame is connected to the machine frame by means of a hydraulic drive track lifting device and can be moved vertically and transversely. The flanged wheels which are the track lifting mechanisms each have a clamping mechanism in the form of a hook or a clamping wheel. The clamping mechanisms can be moved vertically and transversely and are firmly pressed against the outside of the track by means of a drive. In addition to the track lifting mechanisms, the working frame has a further clamping mechanism in the form of a hook which clamps the rail head from below on the outside of the track. The two hooks are arranged longitudinally in front of and behind each other and can be moved vertically and transversely independently of each other by means of their own drive.

The track lifting unit is equipped with an additional track lifting device with a clamping mechanism for gripping one track of a branch line, which has its own track lifting drive. The clamping mechanism is arranged on a carrier frame and can be moved relative to the frame by means of a movement drive. The additional track lifting device is provided at the end connected to the clamping mechanism with a contact element which abuts against the track to be gripped by the clamping mechanism.

[0008] Chinese patent CN1061822A discloses a machine for picking up shoulder pads of a track, having a frame with a diesel engine equipped with a running drive mechanism. The machine has at least two sets of pad picking devices which are spaced apart in the lateral direction of the machine and are adjusted in height by a drive mechanism.

In addition, the machine has a device for adjusting the lateral position by a drive mechanism, for shifting the sleepers in the range of about 30 cm to 100 cm.

[0009] Chinese patent CN102770598A discloses a tamper with additional lifting device, which is configured with a track lifting device positioned immediately in front of the tampering device, and an auxiliary lifting device designed for lifting the branch rail segments branching off from the main track of the turnout. The auxiliary lifting device is attached to a support extending vertically in the longitudinal direction of the tamper, and has a lifting tool which can be fitted on the rail head. In the longitudinal direction of the tamper, the auxiliary lifting device is connected to two rotating rollers which are spaced apart from each other, rotatable in a common rotation plane and disc-shaped, for abutting against two rotating rollers on the first side of the rail head. Flange rollers are provided for abutting against the second side of the rail head and for seating the auxiliary lifting device thereon. The auxiliary lifting device can be pivoted about an axis with respect to the support by means of a drive.

[0010] Chinese patent CN1037751A discloses a machine for moving a track consisting of rails and cross sleepers laterally, having a frame mounted on a running mechanism. The frame is equipped with a track lifting device having roller tools and being adjustable in height and laterally, a device with a straightening tool for straightening individual misaligned sleepers in the plane of the track (adjustable in the longitudinal direction of the track and in height), and at least one set of tamper devices with adjustable tamper heads (adjustable in height). The sleeper straightening device and the track lifting device form a compact working unit which is movable in the longitudinal direction of the track. Both share a common frame carrier which is articulated to the frame by means of height and lateral adjustment hydraulic cylinder piston drive mechanisms.

[0011] The track in the turnout area of our country has not been cleaned and sieved, and the track bureau basically uses manual cleaning and sieving operation for the turnout area, but the operation effect is very poor. Therefore, the demand for large-scale track maintenance machinery for cleaning and sieving the track in the turnout area of our country is huge.

At present, when the cleaning and sieving machine performs turnout operation, the track lifting device is not used, which leads to the overall sinking of the track panel in the turnout area after the turnout cleaning and sieving operation, and the backfilling of the ballast is not ideal. Therefore, it is necessary to design a mechanism which can realize continuous track lifting operation in the turnout area to solve the overall sinking of the track panel in the turnout area and the backfilling of the ballast.
