Description

Technical Field

[0001] The present application relates to the field of railway engineering operations, and in particular to a ballastless track slab changing vehicle and a slab changing method. Background Art

[0002] Slab track is the main track structure used in my country's high-speed railways. The ballastless track slab is an important load-bearing component. As the service time of high-speed railways increases, some track slabs will develop cracks, falling blocks and other defects. In order to ensure the safety, stability and long-term durability of the ballastless track, it is necessary to replace the damaged track slabs.

[0003] There are currently two main methods for track plate replacement: First, the rail-lifting and plate-changing method, which uses special equipment in conjunction with rail-lifting equipment to lift the rails, move the track plates out from the side of the line, and replace them; Second, the horizontal rail-shifting and plate-changing method, which uses special equipment and tooling to shift the rails horizontally, leaving space for vertical lifting of damaged track plates, and completes the track plate replacement with special equipment. The replacement devices or equipment tooling of these two schemes have complex structures, large volumes and weights, low integration, and require a lot of manual labor. In addition, the new track plates need to be transported to the target location in advance by rail transport vehicles and placed on both sides of the track. After replacement, the old track plates are also transported away by rail transport vehicles, resulting in poor adaptability to line conditions and a series of problems such as low plate replacement efficiency, high costs, and the need to mobilize too many resources.

[0004] In view of this, this application is hereby filed. Summary of the Invention

[0054] As shown in FIG. 1, the ballastless track slab replacement vehicle includes a vehicle frame 3, a track lifting device 8, an old slab storage rack 7, a new slab storage rack 6, and a track slab replacement device 5. Figures 3-5As shown, as an embodiment of the present application, the rail pushing device 8 comprises a bearing mounting plate 803, a lateral rail pushing assembly 802, two sets of vertical rail lifting assemblies 804 and a rail clamping assembly 801; the bearing mounting plate 803 is connected to the bottom of the frame 3 of the rail changing trolley; the two sets of vertical rail lifting assemblies 804 are arranged on the bearing mounting plate 803 in lateral direction; the vertical rail lifting assemblies 804 are connected to the lateral rail pushing assembly 802, and the two sets of vertical rail lifting assemblies 804 can move in lateral direction relative to the bearing mounting plate 803; in the embodiment, driving members in the vertical rail lifting assemblies 804 are also installed to provide driving force, such as driving oil cylinders which can provide driving force. The lateral rail pushing assembly 802 is connected to the bearing mounting plate 803, and is used to drive the vertical rail lifting assemblies 804 to move in lateral direction relative to the bearing mounting plate 803; the rail clamping assembly 801 is connected to the bottom end of the vertical rail lifting assembly 804, and is used to grab the rails of the rail line.

[0056] The lateral rail pushing assembly 802 drives the vertical rail lifting assembly 804 to move in lateral direction, and pushes the rails to both sides.

[0057] Specifically, the lateral rail pushing assembly 802 comprises a lateral rail pushing driving member 821, a lateral sliding rail 822 and a sliding block 823; the lateral sliding rail 822 is mounted on the bearing mounting plate 803 and extends in lateral direction; the sliding block 823 is mounted on the lateral sliding rail 822 in cooperation, and the sliding block 823 is connected to the vertical rail lifting assembly 804 and drives the vertical rail lifting assembly 804 to move in lateral direction relative to the lateral sliding rail 822; the lateral rail pushing driving member 821 is connected to the sliding block 823, and is used to provide driving force for the sliding block 823 to move in lateral direction relative to the lateral sliding rail 822.

[0058] In the embodiment, the lateral rail pushing driving member 821 is a driving member for driving the sliding block 823 to move in lateral direction relative to the lateral sliding rail 822, and can be a driving oil cylinder, and the piston rod of the driving oil cylinder is connected to the vertical rail lifting assembly 804, and the driving oil cylinder drives the sliding block 823 to move left and right.

[0059] The transverse rail shifting assembly 802 is provided with multiple groups according to the specific length of the rail to be shifted. As a specific embodiment, the transverse rail shifting assembly 802 is installed on the bearing installation plate 803. Before the rail plate replacement work is performed, the vertical rail lifting assembly 804 vertically lifts the rail of a certain length of fastener, the transverse rail shifting drive 821 drives the two rails to move to the left and right sides respectively, and the transverse rail shifting assembly 802 shifts the rails transversely by a certain width. After the rails are shifted, a space is left for the old rail plate to pass through between the two rails and be lifted up, and the new rail plate is also passed through between the two rails for laying and adjustment.

In the implementation, the locking cross bar drive 902 telescopes vertically to drive the locking cross bar 901 to move up and down through the cooperation between the through hole of the bearing installation plate 803 and the locking guide rod 903 to realize vertical limiting, so that the locking cross bar 901 always extends in the transverse direction and cannot rotate horizontally. The locking block 904 at the end of the locking cross bar 901 tightly abuts against the two rails from the inside to fix the rails. At this time, the upper replacement space is reserved. After the replacement is completed, the rail locking device 9 is reset to unlock, and the lifting and shifting rail device 8 is reset to restore the rails to the original position.
