Description

Technical Field

[0001] This utility model relates to the field of track component technology, specifically a rail connection and correction mechanism. Background Technology

[0002] Steel rails are the main component of railway tracks. Their function is to guide the wheels of locomotives and rolling stock forward, bear the enormous pressure of the wheels, and transmit it to the sleepers.

[0003] Chinese patent application CN201820859057.0 discloses a rail welding joint correction device, including two support beams symmetrically arranged, with support columns fixedly connected to both ends of each beam. An upper pressure plate is fixedly connected between the two support beams on their adjacent sides. A rotating shaft is rotatably connected between the middle of the two support columns on their adjacent sides at both ends of the support beams. A roller is fixedly fitted onto the rotating shaft. Sliding grooves are symmetrically formed on the adjacent sides of the support columns at both ends of the upper pressure plate. A lifting rod is slidably connected between the two sliding grooves. A lower pressure plate is fixedly connected between the adjacent sides of the two lifting rods. However, this design lacks stable clamping of the rails, making it prone to misalignment of the two rail ends and left-right misalignment of the joint during rail welding, increasing workload and reducing work efficiency.

[0004] Chinese patent discloses a rail connection and correction mechanism (authorization announcement number CN217948629U). The limiting component in the vertical side plate of this patent technology can clamp the rail and use the first groove to limit the rail head. When welding two corrected rails, it plays a role in stabilizing the rails and prevents the rails from shifting again after being touched by external force during the welding process, which would cause further inconvenience to the correction work.

[0005] However, it has certain drawbacks: the distance between its two vertical side plates is fixed and cannot be adjusted, which also means that the distance between the lower limit pieces of the two vertical side plates cannot be adjusted. Therefore, it is not suitable for railway tracks where the distance between the left and right guide rails is different. Utility Model Content

[0006] The purpose of this invention is to provide a rail connection correction mechanism to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A rail connection and correction mechanism includes two vertical side plates, left and right. Stabilizing mechanisms are provided at both ends of the lower surface of each vertical side plate. Adjusting mechanisms are provided on both the front and rear sides between the two vertical side plates. Each adjusting mechanism includes a fixed plate. A fixed rod is fixedly connected to the upper surface of the fixed plate. A gear is rotatably connected to the outside of the fixed rod, and a positioning plate is fixedly connected to the upper end of the fixed rod. A positioning bolt is threaded through one end of the positioning plate. Adjusting elements are provided on both the front and rear sides of the fixed rod on the upper surface of the fixed plate.

[0009] As a further embodiment of this utility model: the stabilizing mechanism includes two left and right support blocks, and the two support blocks are rotatably connected to a threaded rod inside. The threaded rod is symmetrically threaded between the two support blocks to two stabilizing blocks, and a notch is provided at the lower end of the opposite side surface of each of the two stabilizing blocks.

[0010] As a further embodiment of this utility model: the adjusting member includes a rack, and a fixing post is fixedly connected to one end of the rack.

[0011] As a further improvement of this invention, the lower end of the positioning bolt is directly opposite the gear.

[0012] As a further embodiment of this utility model: the upper end of the support block is fixed to the lower surface of the vertical side plate, and the upper surface of the stabilizing block is movably attached to the lower surface of the vertical side plate.

[0013] As a further embodiment of this utility model: both racks are slidably connected to the upper surface of the fixing plate, the two racks are respectively located on the front and rear sides of the gear, and both racks are meshed with the gear, and the fixing column is fixed to the vertical side plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This utility model has a stabilizing mechanism, with two stabilizing mechanisms respectively fitted onto the outside of the front and rear guide rails, so that the front and rear guide rails are aligned. This can prevent misalignment when welding the front and rear steel rails.

[0016] 2. This utility model is equipped with an adjustment mechanism. After loosening the positioning bolt in the adjustment mechanism, the two racks can move synchronously, which facilitates the quick adjustment of the distance between the two vertical side plates, thereby quickly adjusting the distance between the left and right stabilizing mechanisms. It is suitable for railway tracks with different distances between the left and right guide rails. Attached Figure Description

[0021] Please see Figure 1 and Figure 2 In this embodiment of the utility model, a rail connection correction mechanism includes two vertical side plates 1 on the left and right. Stabilizing mechanisms 2 are provided at both ends of the lower surface of the vertical side plates 1. The stabilizing mechanism 2 includes two support blocks 3 on the left and right. The upper end of the support block 3 is fixed to the lower surface of the vertical side plate 1. The two support blocks 3 are rotatably connected to a threaded rod 4 inside. The threaded rod 4 is symmetrically threaded between the two support blocks 3. The upper surface of the stabilizing block 5 is movably attached to the lower surface of the vertical side plate 1. A notch 6 is provided at the lower end of the opposite side surface of the two stabilizing blocks 5.

[0022] The threads of the two stabilizing blocks 5 are opposite, that is, when the threaded rod 4 is rotated, the two stabilizing blocks 5 will move towards each other or away from each other at the same time.

[0023] The two stabilizing mechanisms 2 are respectively fitted onto the outside of the rail heads of the front and rear rails, so that the front and rear rails can be kept aligned. This can prevent misalignment when welding the front and rear rails.

[0024] exist Figure 1 and Figure 3 In the middle: Adjustment mechanisms 7 are provided on both the front and rear sides between the two vertical side plates 1. The adjustment mechanism 7 includes a fixed plate 8. A fixed rod 9 is fixedly connected to the upper surface of the fixed plate 8. A gear 10 is rotatably connected to the outside of the fixed rod 9. A positioning plate 11 is fixedly connected to the upper end of the fixed rod 9. A positioning bolt 12 is threaded through one end of the positioning plate 11. The lower end of the positioning bolt 12 is directly opposite the gear 10. Adjustment components 13 are provided on both the front and rear sides of the fixed rod 9 on the upper surface of the fixed plate 8. The adjustment component 13 includes a rack 14. Both racks 14 are slidably connected to the upper surface of the fixed plate 8. The two racks 14 are located on the front and rear sides of the gear 10 respectively. Both racks 14 are meshed with the gear 10. A fixed post 15 is fixedly connected to one end of the rack 14. The fixed post 15 is fixedly connected to the vertical side plate 1.

[0025] Under the action of gear 10, the two racks 14 will move to the middle at the same time or to the sides respectively, so as to quickly adjust the distance between the two vertical side plates 1, and then quickly adjust the distance between the left and right stabilizing mechanisms 2. This is suitable for railway tracks with different distances between the left and right guide rails.

[0026] Tightening the positioning bolt 12 to hold the gear 10 in place prevents the gear 10 from rotating, thereby fixing the spacing of the adjusted vertical side plate 1.

[0027] The working principle of this utility model is as follows: When in use, first adjust the distance between the two vertical side plates 1 according to the distance between the left and right guide rails. After loosening the positioning bolt 12, the distance can be adjusted. After adjustment, tighten the positioning bolt 12 so that it hits the gear 10. Then, place the front and rear stabilizing mechanisms 2 on the front and rear guide rails respectively. Rotate the threaded rod 4 to drive the two stabilizing blocks 5 to move closer until the guide rails are clamped. The front and rear guide rails are aligned by the front and rear stabilizing mechanisms 2. Finally, the workers weld the connection between the front and rear guide rails.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
