Description

Technical Field

[0001] The utility model relates to the technical field of railway track engineering construction, in particular to a simple traveling rail pier. Background Art

[0002] For the construction of ballastless tracks on railways, especially in bridges or underground tunnels where the working space is limited, traveling rails need to be laid on both sides of the ballast bed for the small gantry crane for track laying (lifting track panels, on-line materials, concrete pouring, etc.) to travel back and forth. Since the construction of ballastless tracks is mostly post-station construction, the laying conditions of the traveling rails are restricted. Especially in tunnels, the laying conditions of the traveling rails are restricted by the structures on both sides of the ballastless ballast bed. In addition, to prevent safety hazards such as derailment of the small gantry crane during travel, there are also high requirements for the elevation and smoothness of the tops of the two traveling rails. This leads to an increase in the laying difficulty of the traveling rails in the tunnel, slow construction speed, high input costs, and low efficiency. Summary of the Invention

[0003] The purpose of the utility model is to provide a simple traveling rail pier according to the deficiencies of the above-mentioned prior art. By using the limited space on both sides of the ballastless ballast bed to set up height-adjustable piers and using the small gantry crane for track laying to travel back and forth, the construction speed is fast, the cost is low, and the work efficiency can be greatly improved.

[0004] The purpose of the utility model is achieved by the following technical solutions:

[0005] A simple traveling rail pier for the construction of railway ballastless tracks, characterized in that: it includes an A-type pier arranged inside the cable trench and a B-type pier arranged at the bottom of the middle partition wall. The bottom of the A-type pier is provided with a seat plate that fits and matches the cable trench, and the bottom of the B-type pier is provided with a base plate that fits and matches the bottom of the middle partition wall; the A-type pier and the B-type pier are respectively provided with screw rods, and a press tool for fixing the traveling rail is arranged at the top of the screw rod. The press tool is lifted and lowered under the drive of the screw rod to adjust its elevation.

[0006] The A-type pier includes a seat plate, a seat pipe, a cover seat plate, an adjusting seat, a screw rod and a press tool. The seat pipe is arranged above the seat plate, the cover seat plate is arranged above the seat pipe, the adjusting seat is arranged above the cover seat plate, the screw rod is connected to the adjusting seat and can be lifted and lowered, and the press tool is arranged at the top of the screw rod.

The long pressing strip is arranged at the top of the screw rod, and the small pressing blocks are respectively arranged above both sides of the long pressing strip and are connected to the long pressing strip by bolts.

[0008] The type-b pier includes a base plate, a fixed long plate, a small seat plate, a support pipe, an adjusting seat, a lead screw, and a pressing tool. The fixed long plate is arranged above the base plate. The small seat plate is connected to the fixed long plate by a nut. The support pipe is arranged above the small seat plate. The adjusting seat is arranged above the support pipe. The lead screw is connected to the adjusting seat and can be lifted and lowered. The pressing tool is arranged at the top of the lead screw.

[0015] The features of the present utility model and other related features are further described in detail below with reference to the accompanying drawings through embodiments for the understanding of those skilled in the same industry:

[0016] As Figures 1-4 shown, the markings 1-18 in the figure respectively represent: seat plate 1, seat pipe 2, cover seat plate 3, adjusting seat 4, lead screw 5, long pressing strip 6, small pressing block 7, bolt 8, base plate 9, nut 10, fixed long plate 11, small seat plate 12, support pipe 13, adjusting seat 14, lead screw 15, long pressing strip 16, small pressing block 17, nut 18.

[0017] Embodiment: As Figures 1 to 4As shown, the simple traveling rail pier in this embodiment is used to lay the traveling rail for the paving small crane to travel back and forth, so as to facilitate the construction of the ballastless track of the railway. The simple traveling rail pier in this embodiment is mainly applied to the conditions of covering roads, bridges, and tunnels. The tunnel is in the form of a single-hole double-track, separated by a middle partition wall between the left and right tracks, especially in the condition where the working space in the tunnel is very limited.

[0018] The simple traveling rail pier in this embodiment is divided into Figure 1 and Figure 2 the a-type pier shown in Figure 3 and Figure 4 the b-type pier shown in. The a-type pier is arranged inside the cable trench, and the b-type pier is fixed at the bottom of the middle partition wall. By adjusting the respective lead screws of the two piers, the heights of the two traveling rail surfaces are made the same.

[0019] Specifically, as shown in Figure 1 and Figure 2 , the a-type pier includes a seat plate 1, a seat pipe 2, a cover seat plate 3, an adjusting seat 4, a lead screw 5, a long pressing strip 6, a small pressing block 7, and a bolt 8. Among them, the seat plate 1 is located at the bottom of the a-type pier and is adapted to the structure of the cable trench. The seat pipe 2 is arranged above the seat plate 1 to ensure a certain structural strength of the a-type pier. The cover seat plate 3 is arranged above the seat pipe 2 to enclose the seat pipe 2 and provide a complete setting plane for the upper structure. The adjusting seat 4 is arranged above the cover seat plate 3. The lead screw 5 is connected to the adjusting seat 4 and the lead screw 5 can move up and down through a threaded structure or the like. At the top of the lead screw 5, there is a pressing tool composed of a long pressing strip 6, a small pressing block 7, and a bolt 8. Among them, the long pressing strip 6 is connected to the top of the lead screw 5, and small pressing blocks 7 are respectively arranged on both sides of the long pressing strip 6. The two small pressing blocks 7 are respectively connected to the long pressing strip 6 through bolts 8. When in use, the rail bottom plate of the traveling rail is clamped and fixed between the small pressing block 7 and the long pressing strip 6.

[0020] As shown in Figure 3 and Figure 4 , the b-type pier includes a base plate 9, a nut 10, a fixed long strip plate 11, a small seat plate 12, a support pipe 13, an adjusting seat 14, a lead screw 15, a long pressing strip 16, a small pressing block 17, and a nut 18. Among them, the base plate 9 is located at the bottom of the b-type pier and is adapted to the structure of the bottom of the middle partition wall. The fixed long strip plate 11 is arranged above the base plate 9, and the small seat plate 12 is fixed on the fixed long strip plate 11 through the nut 10. The support pipe 13 is arranged above the small seat plate 12. The adjusting seat 14 is arranged above the support pipe 13. The lead screw 15 is connected to the adjusting seat 14 and the lead screw 15 can move up and down. At the top of the lead screw 15, there are a long pressing strip 16, a small pressing block 17, and a nut 18. The rail bottom plate of the traveling rail is clamped and fixed between the small pressing block 17 and the long pressing strip 16.

[0021] In the specific implementation of this embodiment: Since only the cable trough and the bottom of the middle partition wall on both sides of the ballast slab have the conditions for laying running rails, even if there is a large height difference between the two, it is still possible to adjust the respective lead screws of the two types of piers, namely, the A-type pier and the B-type pier, to make the heights of the two running rail surfaces consistent, ensuring that the elevation and smoothness of the running rail tops meet the requirements.

[0022] Although the above embodiments have detailed the concept and implementation of the purpose of the present invention with reference to the accompanying drawings, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present invention without departing from the scope defined by the claims. Therefore, they will not be elaborated here one by one.
