Description

Technical Field

[0001] This utility model relates to the field of multifunctional track-following handrails made of composite materials, specifically to a track-following handrail for subway lines. Background Technology

[0002] With the development of cities and the increasing demand for transportation in my country, the scale of subway construction is gradually expanding, and the number of new subway lines is increasing year by year. During subway line construction, a large number of multi-functional track-following handrails are needed to assist track inspectors in providing lighting and facilitating the laying of cables and signal lines, while saving space occupied by other devices in subway passages. Therefore, the demand for multi-functional track-following handrails has surged. At the same time, people attach great importance to the safety performance of these handrails. Currently, most multi-functional track-following handrails are made of metal and SMC composite materials. Since metal materials lack insulation properties, leakage could paralyze the entire subway line. Furthermore, metal materials are prone to corrosion due to long-term exposure to humid underground air, requiring significant annual maintenance costs, high labor costs, and environmental damage. On the other hand, SMC composite multi-functional track-following handrails are produced using a molding process. Because the length of multi-functional track-following handrails produced by this process is limited by production equipment and molds, there are many splicing points between the handrails during installation, affecting construction progress and increasing production costs.

[0003] Chinese Patent: A composite material cable trough with light trough and handrail, Authorization Announcement No.: CN212183036 The U-shaped cable trough (or similar handrail) is lightweight and high-strength, has good insulation, high load-bearing capacity, is non-deformable, non-hygroscopic, dimensionally stable, chemically resistant, aging-resistant, has good shock absorption, is non-conductive, and features a simple structure and rapid on-site installation. However, during installation, it requires a mounting bracket, and the trough lacks a reference surface for fixing, which can easily lead to misalignment between the troughs, affecting the orderly laying of cables and signal lines. Furthermore, fixing and disassembling the trough and cover requires external force to cause elastic deformation of the first and second side plates of the trough, forcing the L-shaped slot structure of the cover to engage with the concave gripping structure of the trough. This makes installation extremely cumbersome, and the trough is prone to fatigue under constant elastic deformation, reducing its mechanical properties and failing to ensure stability and vibration resistance under the high-frequency vibrations generated by subway train operation. It also cannot adapt to connection requirements at different angles, making it unsuitable for installation in various subway tunnel environments. Its installation applicability and flexibility are poor. Therefore, a new type of handrail for subway line patrol needs to be designed to solve these problems. Summary of the Invention

[0004] The purpose of this utility model is to address the technical problems existing in the prior art by providing a handrail for subway line track inspection. The specific technical solution is as follows: This utility model provides a handrail for subway line inspection, including a base profile and side covers. The side covers are detachably connected to the base profile. The base profile includes a first side plate, a second side plate, a bottom plate and a shelf connected between the bottoms of the first side plate and the second side plate, which together form a mounting hole. The first side plate, the second side plate and the shelf form a cable trough. The top of the first side plate is U-shaped. The first side plate is detachably connected to the second side plate through the side cover. An LED light groove is provided on the lower surface of the bottom plate. A shelf is provided above the upper surface of the bottom plate. A mounting hole is provided between the shelf and the bottom plate. A partition is provided on the shelf. Two grooves are provided on the upper surface of the shelf. The two grooves are respectively provided on both sides of the partition. Through bolt holes are provided on the shelf and the bottom plate. A bracket is installed below the base profile. The bracket is composed of a horizontal plate, a vertical plate and an inclined plate.

[0005] A further improvement of this utility model is that: the second side plate has an L-shaped structure, a fixing plate is connected to the top of the second side plate, the fixing plate is at 90° with the second side plate, and the fixing plate is provided with fastening holes.

[0006] A further improvement of this utility model is that a first cable groove is formed between the first side plate and the partition plate.

[0007] A further improvement of this utility model is that a second cable groove is formed between the partition and the second side plate.

[0008] A further improvement of this utility model is that the cable trough is in the shape of a semi-open rectangle.

[0009] A further improvement of this utility model is that the included angle β between the LED light groove and the base plate is 55°~75°. This included angle β allows the lighting lamp to illuminate the ground within the maximum range, thereby maximizing the dispersion of light and improving the lighting intensity.

[0010] A further improvement of this utility model is that the lower end of the LED light slot is provided with an inwardly facing L-shaped bayonet structure, the function of which is to secure the outer shell of the lighting lamp well.

[0011] A further improvement of this utility model is that: an L-plate is connected to one side of the U-shaped top near the partition, and the other side extends downward to form the first side plate of the basic profile.

[0012] A further improvement of this utility model is that the side cover is Z-shaped and includes a flat plate, a vertical plate and a pressure plate. One end of the flat plate is connected to the upper part of the vertical plate, and the other end is provided with a slot.

[0013] A further improvement of this utility model is that: the slot matches the L-plate of the base profile, one end of the side cover is tightly engaged with the L-plate through the slot, and the lower part of the vertical plate is connected to a pressure plate.

[0014] This utility model provides safety protection, lighting, and cable and signal line laying for track inspection personnel. Through the bolt through-holes in the base profile and the connection method of embedding the connecting plate into the mounting holes, the freedom of the connecting plate within the mounting holes is constrained. This not only prevents misalignment between base profiles and improves installation quality but also ensures the stability and vibration resistance of the track inspection handrail structure under the high-frequency vibrations generated by subway train operation. Furthermore, the handrail can be easily combined into various shapes according to the subway tunnel environment via the connecting plates to adapt to different angle connection requirements, meeting the installation needs of complex subway tunnel environments and improving installation applicability and flexibility. The handrail is molded from fiber-reinforced resin-based composite material, possessing high electrical insulation and corrosion resistance, ensuring the personal safety of track inspection and maintenance personnel, avoiding unnecessary accidents, and requiring minimal maintenance even in humid underground environments, significantly reducing maintenance costs. It can also be modularly produced in the factory, minimizing environmental impact, and allows for rapid on-site installation, further reducing production costs. Attached Figure Description

The first side plate 5, the second side plate 6, the shelf 11, and the bottom plate 12 together form a mounting hole 13. The first side plate 5 is detachably connected to the second side plate 6 through the side cover 2. The mounting hole 13 is connected in a straight line or a curved line by a straight connecting plate 35 or a curved connecting plate 32. The first side plate 5, the second side plate 6, and the shelf 11 enclose a cable trough 38. The cable trough 38 has a semi-open rectangular structure. The upper surface of the shelf 11 is provided with A partition 14 divides the cable trough into a first cable trough 15 and a second cable trough 16. The first cable trough 15 is formed between the first side plate 5 and the partition 14, and the second cable trough 16 is formed between the partition 14 and the second side plate 6, for laying cables and signal lines. The upper surface of the shelf 11 has two grooves 17 symmetrically distributed on both sides of the partition 14. The two grooves 17 in the shelf 11 and the bottom plate 12 share through bolt holes 18. Round-headed bolts 26 are used to fix the base profile 1 to the bracket 27, or the base profile 1 to the bracket 27 and the straight connecting plate 35 or the curved connecting plate 32. The groove 17 is designed so that the upper arc surface of the round head bolt 26 is lower than the upper plane of the shelf 11, preventing the upper arc surface of the round head bolt 26 from scratching the outer surface of the cable or signal line.
