Description

Technical Field

[0001] This application relates to the field of road embedded parts, and in particular to a high-brightness road embedded part for rail transit. Background Technology

[0002] High-brightness track embedded parts for rail transit are components that are pre-embedded in the concrete structure during the construction of high-brightness tracks for rail transit. They are used to connect, fix, and support track-related facilities (such as track components, communication cable brackets, signal equipment, etc.). Their installation position and accuracy directly affect the stability, safety, and functionality of the rail transit system.

[0003] In rail transit construction, concrete structures are widely used in platforms, track foundations, tunnel linings, and other components. When installing embedded parts, they typically need to be fixed within the concrete. Before concrete pouring, a steel mesh frame must be erected, and the embedded parts must be stably placed on this frame. However, during concrete pouring, due to the fluidity of the concrete and the impact force generated, the embedded parts are easily subjected to impact, leading to positional shifts and movement. This positional deviation can cause inaccurate alignment of subsequently installed track facilities, affecting track smoothness and normal equipment operation, and may even create safety hazards.

[0004] Regarding the aforementioned technologies, the inventors believe that there is a defect of unstable placement when the embedded parts are placed in the concrete steel mesh frame. Therefore, a high-brightness road embedded part for rail transit is proposed to solve the above problems. Utility Model Content

[0005] To address the issue of unstable placement of embedded parts within concrete steel mesh, this application provides a high-brightness road embedded part for rail transit.

[0006] This application provides a high-brightness road embedded component for rail transit, which adopts the following technical solution:

[0007] A high-brightness road embedded component for rail transit includes a metal support plate. Fixing screws are fixedly installed on the upper surface of the metal support plate near its four corners. The bottom ends of the fixing screws extend below the metal support plate and are fixedly installed with embedded supports. A positioning frame is provided below the metal support plate. Several guide grooves are formed through the upper surface of the positioning frame at positions corresponding to the embedded supports. Movable components are movably installed inside the guide grooves. A positioning plate is fixedly installed at the bottom end of the movable component through the guide groove. A positioning screw is fixedly connected to the center of the top of the positioning frame. An adjusting support rod is rotatably installed above the positioning frame, extending from the center of the top of the movable component. Connecting components are hinged to the tops of multiple adjusting support rods. A support mechanism is also provided below the positioning frame for stable support of the embedded supports.

[0008] Preferably, the support mechanism includes a rotating support rod, which is symmetrically rotatably mounted at the bottom edge of the positioning plate. A guide rod is fixedly connected to the top edge of the rotating support rod, and an adjusting sleeve is movably mounted on the outer surface of two guide rods that are close to each other. A positioning plate is symmetrically welded to one side of the adjusting sleeve.

[0009] Preferably, the connector has a through hole at the center of its top end, the connector is sleeved on the outer surface of the positioning screw, and a threaded fitting is rotatably installed at the center of the top end of the connector. The threaded fitting has a through hole inside, and the threaded fitting is threadedly connected to the outer surface of the positioning screw.

[0010] Preferably, an arc-shaped groove is provided on one side of the positioning plate, and one side of the outer surface of the pre-embedded support is located inside the arc-shaped groove, and the pre-embedded support and the arc-shaped groove are engaged with each other.

[0011] Preferably, the adjusting sleeve has a through-hole fixed long groove, the outer diameter of the guide rod is smaller than the distance between the front and rear ends of the inner wall of the fixed long groove, and the guide rod and the fixed long groove are interlocked.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The positioning frame, guide groove, and movable parts work together to achieve initial positioning of the embedded support. The rotating support rod, guide rod, adjusting sleeve, and positioning plate of the support mechanism can stably support the embedded support and prevent positional displacement caused by the impact of concrete pouring. The threaded fitting and positioning screw work together to tighten the adjusting support rod and connecting parts, enhance the overall structural stability, and ensure accurate installation of the embedded parts.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a high-brightness road embedded component for rail transit. (Refer to...) Figure 1-3 A high-brightness road embedded component for rail transit includes a metal support plate 1. Fixing screws 2 are fixedly installed on the upper surface of the metal support plate 1 near its four corners. The bottom ends of the fixing screws 2 extend to the underside of the metal support plate 1 and are fixedly installed with embedded support components 3. A positioning frame 4 is provided below the metal support plate 1. Several guide grooves 5 are formed through the upper surface of the positioning frame 4 at positions corresponding to the embedded support components 3. Movable components 6 are movably installed inside the guide grooves 5. A positioning plate 7 is fixedly installed at the bottom end of the movable component 6 through the guide groove 5. An arc-shaped groove is formed on one side of the positioning plate 7, and one side of the outer surface of the embedded support component 3 is located inside the arc-shaped groove. The embedded support 3 and the arc-shaped groove engage with each other. The positioning frame 4 is fixedly connected to the top center of the positioning screw 8. The movable part 6 extends to the top center of the positioning frame 4 and is rotatably installed with an adjusting support rod 9. Multiple adjusting support rods 9 are hinged to the top of the connecting part 10. The top center of the connecting part 10 has a through hole. The connecting part 10 is sleeved on the outer surface of the positioning screw 8. The top center of the connecting part 10 is rotatably installed with a threaded fitting 11. The threaded fitting 11 has a through threaded hole. The threaded fitting 11 is threadedly connected to the outer surface of the positioning screw 8. A support mechanism is also provided below the positioning frame 4 for stable support of the embedded support 3.

[0020] The fixing screw 2 and the embedded support 3 are fixed to the metal support plate 1 by welding. The movable part 6 slides in the guide groove 5, driving the positioning plate 7 to move. The arc-shaped groove of the positioning plate 7 engages with the embedded support 3, achieving initial positioning. Rotating the threaded assembly 11, the threaded engagement causes the threaded assembly 11 to move on the positioning screw 8, pressing the connecting part 10. The position of the movable part 6 is fixed by the hinged adjusting rod 9, enhancing positioning stability.

[0021] Reference Figure 2 and Figure 3 The support mechanism includes a rotating support rod 12, which is symmetrically rotated and installed at the bottom edge of the positioning plate 7. A guide rod 13 is fixedly connected to the top edge of the rotating support rod 12. An adjusting sleeve 14 is movably installed on the outer surface of two guide rods 13 that are close to each other. A positioning plate 15 is symmetrically welded to one side of the adjusting sleeve 14. A fixed long groove is opened through the inside of the adjusting sleeve 14. The outer diameter of the guide rod 13 is smaller than the distance between the front and rear ends of the inner wall of the fixed long groove. The guide rod 13 and the fixed long groove are interlocked.

[0022] By rotating the support rod 12 around the positioning plate 7, the guide rod 13 slides in the fixed long groove of the adjusting sleeve 14, adjusting the position of the positioning plate 15 so that the positioning plate 15 is attached to the steel mesh, dispersing the impact force during concrete pouring and stabilizing the embedded support 3.

[0023] The implementation principle of a high-brightness road embedded component for rail transit according to an embodiment of this application is as follows: First, the fixing screw 2 and the pre-embedded support 3 are fixed to the metal support plate 1 by welding. The movable part 6 slides in the guide groove 5, driving the positioning plate 7 to move, so that the arc-shaped groove of the positioning plate 7 engages with the pre-embedded support 3, achieving initial positioning. Rotating the threaded assembly 11, the threaded assembly 11 moves on the positioning screw 8 by utilizing the thread engagement, pressing the connecting part 10, and fixing the position of the movable part 6 by the hinged adjusting support rod 9, enhancing positioning stability. In the support mechanism, the rotating support rod 12 rotates around the positioning plate 7, and the guide rod 13 slides in the fixed long groove of the adjusting sleeve 14, adjusting the position of the positioning plate 15, so that the positioning plate 15 is attached to the steel mesh frame, dispersing the impact force during concrete pouring and stabilizing the support of the pre-embedded support 3. The entire device solves the problem of unstable placement of the embedded part in the concrete steel mesh frame through the coordinated action of multiple components, prevents positional displacement during pouring, and ensures the installation accuracy and stability of the high-brightness road embedded component for rail transit.
