Description

Technical Field

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

[0002] Ballastless track is the primary track structure for my country's high-speed railways. In recent years, with the increase in high-speed rail operation, the combined effects of train loads, the external environment, and other factors have caused some structural damage and defects to the ballastless track. As a critical load-bearing component of the ballastless track structure, track slabs, if not promptly addressed, can affect their structural bearing capacity and track geometry, posing a significant risk to train safety. Severely damaged track slabs require complete replacement.

[0003] Because track slabs require extremely high precision in their installation, adjusting their positions is particularly time-consuming. High-speed railways also implement a time-limited repair system, which places strict time constraints on construction, further complicating track slab replacement.

[0004] Existing track plate fine-adjustment devices are mostly installed on both sides of the track plate. During the adjustment process, the fine-adjustment devices need to cooperate with each other to achieve fine-tuning of the track plate's installation position. This adjustment process is prone to the following problems: First, this adjustment method can cause structural deformation of the fine-adjustment device due to the lack of freedom of movement during fine-adjustment; second, fine-adjusting the track plate requires multiple people to operate simultaneously, which is inefficient.

[0005] In view of this, this application is hereby filed. Summary of the Invention

[0071] like Figure 1-Figure 2 As shown, the ballastless track plate changing vehicle provided in the embodiment of the present application includes: a frame 3, a rail lifting device 8, an old plate storage rack 7, a new plate storage rack 6 and a track plate replacing device 5.

[0072] During implementation, the frame 3 serves as the load-bearing installation body, used to carry the entire vehicle and various working devices; the rail lifting device 8 is installed at the bottom of the frame 3, used to grab the rails on both sides of the track line, lift the rails off the ground and push them a certain distance to both sides; the old plate storage rack 7 is installed on the frame 3, used to store old track plates; the new plate storage rack 6 is installed on the frame 3, used to store new track plates; the track plate replacement device 5 is installed on the frame 3, used to lift the old track plates, transport the old track plates to the old plate storage rack 7, and grab the new track plates on the new track plate storage rack 6 and transport them to the target placement position; it realizes the automatic replacement of old and new track plates, greatly improves the plate replacement speed, and does not require the cooperation of special equipment or additional rail transport vehicles, but also reduces personnel participation and reduces the cost of plate replacement.

[0079] Specifically, the transverse rail assembly 802 includes a transverse rail driving component 821, a transverse slide rail 822 and a slider 823; the transverse slide rail 822 is installed on the load-bearing mounting plate 803 and extends in the transverse direction; the slider 823 is installed in cooperation with the transverse slide rail 822, and the slider 823 is connected to the vertical rail lifting assembly 804, driving the vertical rail lifting assembly 804 to move relative to the transverse slide rail 822; the transverse rail driving component 821 is connected to the slider 823, and is used to provide a driving force for the slider 823 to move relative to the transverse slide rail 822.

[0080] During implementation, the transverse rail driving component 821 is a driving component that drives the slider 823 to move along the transverse slide rail 822. It can be a driving cylinder. The piston rod of the driving cylinder is connected to the vertical rail lifting assembly 804. The driving cylinder drives the slider 823 to drive the rail clamping assembly 801 to move left and right.

[0081] Multiple groups of transverse rail deflection assemblies 802 are provided according to the specific length of the rails to be deflected. As a specific embodiment, transverse rail deflection assemblies 802 are respectively installed on the load-bearing mounting plates 803. Before replacing the rail plate, the vertical rail lifting assembly 804 will vertically lift the rails with a certain length of fasteners removed, and the transverse rail deflection driving component 821 will drive the two rails to move to the left and right sides respectively, and the transverse rail deflection assembly 802 will deflect the rails laterally to a certain width; after the rails are deflected, space is left, the old rail plate is passed through between the two rails and lifted up, and the new rail plate is also passed through between the two rails.

[0082] While the rails are being pushed into place, in order to prevent the driving parts of the horizontal rail pushing assembly 802, the vertical rail lifting assembly 804 and the rail clamping assembly 801 from failing, such as preventing the oil cylinder from failing, the rail locking device 9 can be extended and positioned between the two rails to fix the rails on the railway line; at least two sets of rail locking devices 9 are provided, which are installed between the rails on the railway line to fix the rails on the railway line.

[0084] As a specific embodiment, the rail locking device 9 also includes a locking guide rod 903, the bottom end of which is connected to the locking crossbar 901, and the top end passes through the through hole of the bearing mounting plate 803 and extends in the vertical direction. The locking crossbar driver 902 can be a telescopic oil cylinder or a telescopic motor, or other driving parts with telescopic function; in implementation, the locking crossbar driver 902 is telescopic in the vertical direction, driving the locking crossbar 901 to move up and down through the through hole of the bearing mounting plate 803 and the locking guide rod 903 to achieve vertical limit, so that the locking crossbar 901 always extends in the horizontal direction and does not produce horizontal rotation; the locking block 904 at the end of the locking crossbar 901 presses the two rails from the inside to complete the fixation of the rails. At this time, the upper plate replacement space is reserved. After the plate replacement is completed, the rail locking device 9 is reset and unlocked, and the rail lifting device 8 is reset to restore the rails to their original position.
