Description

Technical Field

[0001] This utility model relates to the field of underground road spike technology, specifically to detachable underground road spikes. Background Technology

[0002] In the field of traffic and road infrastructure, underground road studs are widely used in highways, urban roads and parking lots as key equipment to assist traffic guidance and improve road condition visibility at night or in bad weather. By embedding them into the road surface, they achieve integrated integration with the road, ensuring that vehicles are not easily damaged by external forces during driving and guaranteeing long-term stability.

[0003] However, the existing installation structure of buried road studs has significant defects. Currently, most buried road studs adopt a fixed installation design, which requires the road stud body to be fixed to the road base through concrete pouring or strong adhesive to form an inseparable connection structure. Once the buried road stud has problems such as circuit failure, shell damage, or light source failure, the entire road surface of the installation area must be dug up with special tools to remove the faulty road stud for replacement or repair. This maintenance method not only consumes a lot of manpower, material resources and time costs, but also damages the integrity of the road surface. The resulting road repair marks may affect the road aesthetics and driving smoothness. Especially in sections with high traffic volume, maintenance work can easily cause traffic congestion or safety hazards. With the increasing demand for efficiency in traffic facility maintenance, traditional fixed buried road studs are no longer suitable for convenient and low-cost operation and maintenance needs. Therefore, we propose detachable buried road studs. Utility Model Content

Utilizing a separate structure of the fixed base, the spike's inner liner fixing component, and the protective sealing component, when problems such as a faulty LED panel or damaged inner liner occur, there's no need to dig up the entire road surface as with traditional road spikes. Only the mounting bolts of the protective sealing component and the inner liner fixing component need to be removed to individually remove the damaged inner liner for repair or replacement. This significantly reduces manpower and material resources, lowers maintenance costs and construction difficulty, and avoids damage to road integrity caused by road excavation, minimizing traffic disruption and mitigating traffic congestion or safety hazards caused by maintenance work. Furthermore, the combination of a waterproof support plate and a high-strength PC stainless steel reinforcing plate in the protective sealing component ensures convenient disassembly while effectively achieving waterproof sealing and pressure resistance, guaranteeing long-term stable operation of the road spike in complex road environments.

Wiring connection hole 17: It is opened on the bottom surface of the inner surface of the rail spike inner tube 9 and is used to connect the external wiring of the rail spike inner tube 9 to ensure the connection between the light panel 14 and the external power supply line. Working principle: When this utility model is needed, first, the fixing base 1 is pre-embedded in the pre-reserved installation groove in the road surface. The position is adjusted to ensure it is flush with the road surface. The fixing base 1 serves as the basic support for the entire road stud. The annularly distributed mounting threaded holes 8 on its top surface provide a precise positioning reference for the subsequent fixing of the protective sealing components. The road stud inner tube 9, pre-installed with the top plate transparent protective cover 11 and the light-emitting plate 14, is placed inside the fixing base 1, ensuring the bottom of the inner tube is flush with the inner side of the base. Then, the mounting support waterproof plate 3 and the road stud inner tube fixing plate 5 are placed sequentially on the top surface of the road stud inner tube 9. At this time, it is necessary to... Ensure precise alignment of the holes in the three components—namely, the inner liner mounting connection hole 16 of the inner liner fixing plate 5, the fixing hole 13 of the mounting support waterproof plate 3, and the inner liner mounting threaded hole 10 of the inner liner 9 should be concentric. Pass the inner liner fixing bolt 6 sequentially through the inner liner mounting connection hole 16 and the fixing hole 13, finally threading it into the inner liner mounting threaded hole 10 and tightening it. The axial pressure of the bolts firmly secures the inner liner 9, the mounting support waterproof plate 3, and the inner liner fixing plate 5. Simultaneously, the mounting support waterproof plate 3 can initially prevent external moisture from seeping into the inner liner. Confirm the installation... After the supporting waterproof plate 3 is tightly fitted to the top surface of the fixed base 1, the stainless steel reinforcing plate 4 is placed over the top surface of the supporting waterproof plate 3. Ensure that the mounting connecting hole 15 of the stainless steel reinforcing plate 4, the connecting hole 12 of the supporting waterproof plate 3, and the mounting threaded hole 8 of the fixed base 1 are concentrically aligned. Pass the mounting fixing bolts 7 sequentially through the mounting connecting holes 15 and 12, thread them into the mounting threaded hole 8, and tighten them. This ensures that the stainless steel reinforcing plate 4, the supporting waterproof plate 3, and the fixed base 1 form a sealed unit. If the road spike experiences circuit failure or inner liner damage, use a tool to unscrew the mounting fixing bolts. Bolt 7: Since the bolt and the mounting threaded hole 8 are detachable threaded connections, the bolt can be directly removed from the mounting connecting hole 15 and connecting hole 12. Then, remove the stainless steel reinforcing plate 4 and the mounting support waterproof plate 3 upwards to expose the rail spike inner liner fixing assembly below. Unscrew the inner liner fixing mounting bolt 6. Similarly, taking advantage of the detachable nature of the threaded connection, remove the bolt from the inner liner mounting connecting hole 16 and fixing hole 13. Then remove the rail spike inner liner fixing plate 5. The rail spike inner liner 9 can then be removed from the inside of the fixing base 1 for fault repair or replacement. After the repair is completed, decouple and reinstall according to the installation sequence.
