Description
Technical Field
[0001] This utility model relates to the field of rail transit construction technology, specifically to a track transition construction support structure with vibration reduction function at a connecting passage. Background Technology
[0002] Currently, in the underground construction of rail transit, temporary rails need to be erected at connecting passages to serve as a transitional link in the construction process. Therefore, effective support for the rails is necessary, especially ensuring their stability and positional accuracy. However, due to the vibrations experienced during construction, how to effectively and stably support the rails is a pressing technical problem that needs to be solved. Summary of the Invention
[0003] The purpose of this utility model is to address the shortcomings of the prior art by providing a track transition construction support structure with vibration reduction function at connecting passages. By designing a support bracket assembled from steel components, the steel rails are effectively supported, thereby improving the construction effect.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A track transition construction support structure with vibration reduction function at a connecting passage is characterized by: including lead screws on both sides, with a square tube and a connecting pipe arranged between the lead screws, and connecting pipes symmetrically arranged on both sides of the square tube. The connecting pipes are threadedly engaged with the screw section of the lead screw, allowing the connecting pipes to rise and fall on the lead screws. A certain distance is maintained between the connecting pipes and the square tube to form a support position for the rail. The bottom of the connecting pipe and the bottom of the square tube are connected to form an integral structure by a connecting steel plate. Square iron is provided on the top of the connecting pipe and the top of the square tube, and fastening screws for fixing the rail in the support position are provided on the square iron.
[0006] A tray is provided on the connecting steel plate at the position corresponding to the support position; a vibration damping pad is provided on top of the tray.
[0007] The connecting steel plate and the connecting pipe, as well as the connecting steel plate and the square tube, are connected by connecting bolts.
[0008] The bottom end of the lead screw is within a certain distance above the bare section.
[0009] The advantages of this utility model are: it can effectively support the rails at the connecting passage and ensure the positional accuracy of the rails; the structure is simple and reasonable, with a certain adjustment capability, which is beneficial to construction; it is easy to install and dismantle, can be recycled, and is suitable for promotion. Attached Figure Description
[0010] Figure 1 This is a schematic diagram of the structure of this utility model;
[0011] Figure 2 for Figure 1 Top view. Detailed Implementation
[0012] The features of this utility model and other related features will be further described in detail below with reference to the accompanying drawings and embodiments, so as to facilitate the understanding of those skilled in the art:
[0013] like Figure 1-2 As shown in the figure, the numbers 1-11 represent: 1. Screw rod 2. Square tube 3. Connecting pipe 4. Connecting steel plate 5. Square iron 6. Fastening screw 7. Connecting bolt 8. Tray 9. Smooth rod section 10. Rail bottom slope 11.
[0014] Example: Figure 1 and Figure 2 As shown, in this embodiment, the track transition construction support structure with vibration reduction function at the connecting passage includes two lead rods 1 on both sides. Both lead rods 1 are arranged vertically and include a screw section 2 and a smooth rod section 10 along their height direction. The smooth rod section 10 ensures that the lead rod 1 can be stably erected in its setting position.
[0015] A square tube 3 and a connecting tube 4 are arranged between the lead screw 1, with the connecting tube 4 symmetrically arranged on both sides of the square tube 3. One side of the connecting tube 4 is threadedly connected to the screw section 2 of the lead screw 1, allowing the connecting tube 4 to move up and down on the lead screw. The other side of the connecting tube 4 is at a certain distance from the square tube 3 to form a support position for the rail. The bottom of the connecting tube 4 and the bottom of the square tube are connected to form an integral structure by a connecting steel plate 5. The connecting steel plate 5 corresponds to the support position of the rail, meaning that the rail can be supported on the connecting steel plate 5.
[0016] In this embodiment, the connecting steel plate 5 and the connecting pipe 4, as well as the connecting steel plate 5 and the square tube 3, are connected by connecting bolts 8 to facilitate the installation, dismantling, and recycling of the bracket.
[0017] Square irons 6 are respectively provided on the top of the connecting pipe 4 and the top of the square pipe 3. Fastening screws 7 for fixing the rail in the support position are provided on the square irons 6. The fastening screws on the connecting pipe 4 are opposite to the fastening screws on the square pipe 3, so as to tighten the rail from both sides.
[0018] In this embodiment, a tray 9 is provided at the position of the connecting steel plate 5 corresponding to the support position, and a rail bottom slope 11 is provided on the tray 9 to ensure the positional accuracy of the rail. A vibration damping pad is further provided above the tray 9 to reduce vibration and ensure that the rail is not affected by vibration after being fixed.
[0019] Although the above embodiments have described the concept and embodiments of the present invention in detail with reference to the accompanying drawings, those skilled in the art will recognize that various improvements and modifications can still be made to the present invention without departing from the scope of the claims, and therefore will not be elaborated here.
