The sleeper crane 2 is a crawler excavator.

The track of the sleeper crane 2 is a rubber track, so that the track and the sleeper can be prevented from being damaged.

The working principle is as follows:

when the sleeper-changing machine is used, the ballast pushing machine 1 is pulled by the sleeper crane 2 to move on a rail, and the ballast pushing machine 1 and a hydraulic system on the sleeper crane 2 respectively control the operation of the ballast pushing machine 1 and the sleeper crane.

When the sleeper crane 2 drives the ballast pushing machine 1 to operate to a specified working position, the ballast pushing machine 1 is locked on a rail through the rail locking devices 3 on the front machine body 11 and the rear machine body 12, and the ballast pushing machine 1 is prevented from moving under stress when the ballast is pushed. The tilting hydraulic cylinder 53 is controlled to stretch and retract to drive the push shovel 51 to change the pitch angle, the left lifting hydraulic cylinder 56 and the right lifting hydraulic cylinder 57 are controlled to stretch and retract to drive the push shovel 51 to ascend and descend, and the left push-pull hydraulic cylinder 58 and the right push-pull hydraulic cylinder 59 are controlled to stretch and retract to drive the push shovel 51 to move back and forth. When the push shovel 51 ascends and descends, because the cylinder bodies of the left push-pull hydraulic cylinder 58 and the right push-pull hydraulic cylinder 59 are hinged with the rear machine body 12, the cylinder rod ends of the left push-pull hydraulic cylinder 58 and the right push-pull hydraulic cylinder 59 can swing up and down along with the lifting of the push shovel 51, and when the cylinder bodies of the left push-pull hydraulic cylinder 58 and the right push-pull hydraulic cylinder 59 are parallel to the left consequent beam 14 and the right consequent beam 15, the cross beam 52 can be pushed to drive the push shovel 51, the left sliding sleeve 54, the right sliding sleeve 55, the left lifting hydraulic cylinder 56 and the right lifting hydraulic cylinder 57 to move back and forth on the left consequent beam.

After the pressure pads and nuts between the sleepers and the rails to be replaced are loosened manually, the push shovel 51 can push the railway ballast and the sleepers to loosen the sleepers and fall into ballast pits, and then the push shovel 51 retreats to leave a sleeper hanging space for the sleeper crane 2. When the sleeper is hoisted, the excavating arm 21 of the sleeper crane 2 extends downwards into the space between two rails from the gap between the left longitudinal beam and the right longitudinal beam, the sleeper gripper 22 at the front end of the excavating arm firstly grips the sleeper to be replaced, then the sleeper gripper 22 carries the sleeper to horizontally rotate for 90 degrees, so that the direction of the sleeper is the same as that of the rails, the excavating arm 21 can be lifted, and the sleeper is hoisted out from the space between the left longitudinal beam 14 and the right longitudinal beam 15 and placed on a roadbed or other positions. The process of replacing the sleeper is basically the same, the sleeper crane 2 firstly hoists the sleeper into the lower part of two rails from the position between the left and right

longitudinal beams

14 and 15, then horizontally rotates the sleeper by 90 degrees to enable the sleeper to be vertical to the rails, and then lifts the sleeper to enable the upper side of the sleeper to lean against the bottom surface of the rails. At the moment, the ballast pulling device 6 can be started, the downward extending hydraulic cylinder 64 is controlled to extend, the bottom plate 67 is driven to extend downwards to the lowest position, the ballast pulling hydraulic cylinder 66 is controlled to extend and contract, and the ballast pulling plate 65 can pull the road ballasts in the related range to the positions below the two ends of the sleeper so as to prevent the sleeper from falling. After the ballast-removing track is removed, the ballast-removing device 6 is controlled to retract upwards to the original position, and then the sleeper is installed on the rail by a press pad and a nut manually, so that the sleeper gripper can be loosened, and other sleepers can be replaced. After the sleepers are replaced, ballast pits below the sleepers and between the sleepers are filled with ballast by using the push shovels 51, and finally, sleeper replacement is completed. The ballast cleaning machine is convenient to cooperate with the replacement of the sleeper, and the sleeper replacement efficiency is higher.

When the sleeper replacing machine avoids a train to get off the track, firstly, the connection between the ballast pushing machine 1 and the sleeper crane 2 needs to be disconnected, the ballast pushing machine 1 can get off from the rail by using the track descending device 4 and a lower rail, and the sleeper crane 2 can be automatically driven off from the rail.
