Description

Technical Field

[0001] This utility model belongs to the field of cable brackets, and in particular relates to a lighting line bracket for urban rail transit. Background Technology

[0002] Rail transit refers to a type of transportation or system where vehicles operate on specific tracks. The most typical rail transit system is the railway system, composed of traditional trains and standard railways. With the diversified development of train and railway technology, rail transit has taken on more and more types, not only covering long-distance land transportation but also being widely used in short- and medium-distance urban public transportation, such as subways. Subways are a type of high-speed, high-capacity urban rail transit system that has gradually developed from underground railway systems. With the continuous development of society and the economy, subways have been widely used in cities. Originally, subways referred to urban rail transit systems operating underground, but with the development of urban rail transit systems, sometimes parts of the subway lines are laid above ground due to construction conditions.

[0003] To facilitate the electrification of rail transit, cables, including lighting lines, are typically laid along the rail lines. This requires drilling holes in the walls of the tracks to install brackets, which then neatly support the cables. However, existing brackets have limited load-bearing capacity and stability due to their simple structure. Furthermore, while existing brackets can support lighting lines, the lighting fixtures themselves still need to be installed independently on walls or on separate mounting brackets. This not only increases the workload for workers but also affects the construction progress and cost of urban rail transit to some extent. Utility Model Content

[0004] The purpose of this invention is to provide a lighting line bracket for urban rail transit that not only improves load-bearing capacity and stability but also allows for the installation of lighting equipment.

[0005] The aforementioned lighting line bracket for urban rail transit includes a mounting plate, which consists of a vertical plate and two horizontal plates respectively fixed to the left and right walls of the vertical plate. A support plate is fixed to the front wall of the upper end of the vertical plate, and support rods are fixed to the front walls of both horizontal plates. A fixing component for securing cables is fixed to the top of the support plate and one of the support rods. An upwardly inclined connecting plate is fixed to the front wall of the lower end of the vertical plate. A reinforcement mechanism for installing lighting equipment is detachably installed at the front end of the support plate. The movable ends of the connecting plate and the two support rods are detachably installed on the reinforcement mechanism.

[0006] Furthermore, the vertical plate and the two horizontal plates are integrally formed and have a cross-shaped structure. The upper end, lower end and middle of the vertical plate and the ends of the two horizontal plates away from the vertical plate are all provided with front and rear connecting fixing holes.

[0007] Furthermore, the fixing component includes a support base, the top of which has an arc-shaped groove for placing the cable, and a rotating shaft that is rotatably fitted through the rear end of the support base. Both ends of the rotating shaft are fixed with elastic arc-shaped rods for pressing the cable downward into the arc-shaped groove. The movable ends of the two arc-shaped rods are connected by limiting rods. The front sidewall of the support base has several limiting grooves from top to bottom for locking the limiting rods.

[0008] Furthermore, the reinforcement mechanism includes a reinforcement plate vertically arranged below the support plate. Several threaded rods are fixed to the top of the reinforcement plate. Each threaded rod passes through the front top of the support plate independently, and a nut is fitted at one end of the rod passing through the support plate. Several mounting holes for installing lighting equipment are evenly opened on the front sidewall of the reinforcement plate.

[0009] Furthermore, the front sidewall of the connecting plate is also evenly provided with several mounting holes for installing lighting equipment.

[0010] Furthermore, the left and right sides of the reinforcing plate are both fixed with rearward-facing connecting grooves, and the movable ends of the two support rods are both fixed with inserts. The two inserts are respectively inserted into the corresponding connecting grooves. The rear side wall at the lower end of the reinforcing plate is provided with a slot, and the movable end of the connecting plate is also fixed with an insert. The insert on the connecting plate is inserted into the slot.

[0011] Furthermore, the front sidewalls of both the connecting groove and the reinforcing plate are fitted with bolts to improve the stability of the connection between the support rod and the connecting plate and the reinforcing plate.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This utility model utilizes a cross-shaped mounting plate to connect the reinforcing plate, support plate, support rod, and connecting plate into a single unit. This allows the reinforcing plate and connecting plate to support the support plate and support rod, improving the device's load-bearing capacity for cables. The support rod also enhances the device's lateral anti-interference strength, thus improving its stability. Furthermore, since the reinforcing plate, support plate, support rod, and connecting plate are all detachably connected, the support rod can also fix the support base, increasing the number of cables the device can support. The support base includes an arc-shaped rod, a limiting rod, and a rotating shaft. By engaging the limiting rod in limiting grooves at different heights, the cable is pressed into the arc-shaped groove with a certain force, preventing it from detaching from the support base under the influence of wind, vibration, etc. It also allows for the fixing of cables of different diameters and quantities, expanding its applicability. Additionally, by providing mounting holes for lighting equipment on the reinforcing plate, workers no longer need to create additional holes or fixing supports for lighting equipment. This not only reduces the construction cost and workload of urban rail transit workers but also accelerates the construction progress of urban rail transit to some extent.

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0021] Example 1

[0022] This embodiment describes a lighting line support for urban rail transit, including a mounting plate. The mounting plate consists of a vertical plate 11 and two horizontal plates 1 respectively fixed to the left and right walls of the vertical plate 11. Figure 1 , Figure 2 and Figure 5 As shown, the vertical plate 11 and the two horizontal plates 1 are integrally formed and have a cross-shaped structure. The upper end, lower end and middle of the vertical plate 11 and the end of the two horizontal plates 1 away from the vertical plate 11 are provided with front and rear through fixing holes 7. The vertical plate 11 and the two horizontal plates 1 are installed on both sides of the urban rail transit through the fixing holes 7 and with the help of expansion screws. In actual application, the horizontal plate 1 and the vertical plate 11 can also be arc-shaped to adapt to the installation environment of underground urban rail transit.

[0023] A support plate 12 is fixed to the front side wall of the upper end of the vertical plate 11, such as Figure 1 and Figure 2 As shown, the support plate 12 is horizontal and perpendicular to the front side wall of the vertical plate 11; in practical applications, the support plate 12 and the vertical plate 11 are fixed by welding or are formed as one piece.

[0024] refer to Figures 1 to 5 Support rods 2 are fixed to the front sidewalls of both horizontal plates 1. Support bases 13 are fixed to the top of support plate 12 and one of the support rods 2. The top of the support base 13 has an arc-shaped groove for placing the cable 9. A rotating shaft 17 is inserted through the rear end of the support base 13 and rotates with it. Both ends of the rotating shaft 17 are fixed with elastic arc-shaped rods 15 for pressing the cable 9 downward into the arc-shaped groove. The movable ends of the two arc-shaped rods 15 are connected by limiting rods 16. The front sidewall of the support base 13 has several limiting grooves from top to bottom for locking the limiting rods 16 (the support base 1 in this paragraph). 3. The rotating shaft 17, the arc-shaped rod 15, and the limiting rod 16 together constitute the fixing assembly for locking the cable 9. In practical applications, the depth of the arc-shaped groove can be increased so that the cable 9 is completely placed in the arc-shaped groove. A screw that is threaded to the upper end of the support base 13 and used to lock the arc-shaped groove is also installed therein. In this embodiment, by locking the limiting rod 16 in the limiting groove at different heights, the cable 9 can be pressed into the arc-shaped groove with a certain force to prevent the cable 9 from falling off the support base 13 under the action of wind, vibration, and other factors. It can also fix cables 9 of different diameters and quantities, thus improving the applicability.

[0025] like Figure 3 and Figure 4 As shown, the arc rod 15, the rotating shaft 17 and the limiting rod 16 are all made of stainless steel and are in the form of a rectangular frame structure with two opposite sides in the shape of arcs. The rear end of the support base 13 has a left and right through hole for the rotating shaft 17 to be installed independently. The limiting groove is a left and right through structure.

[0026] like Figure 1 and Figure 2 As shown, an upwardly inclined connecting plate 5 is fixed to the front side wall of the lower end of the vertical plate 11. A reinforcing plate 4 is vertically installed below the support plate 12. Several threaded rods are fixed to the top of the reinforcing plate 4. Each threaded rod passes independently through the front top of the support plate 12, and a nut 10 is fitted onto one end of the rod passing through the support plate 12. Several mounting holes 8 for installing lighting equipment are evenly opened on the front side wall of the reinforcing plate 4. (The reinforcing plate 4, threaded rods, nuts 10, and mounting holes 8 in this paragraph constitute the reinforcing mechanism for installing lighting equipment. In practical applications, it is not necessary to open holes on the reinforcing plate 4.) Mounting holes 8 are provided, and a U-shaped fixing frame is fixed to the front side wall of the reinforcing plate 4 (mounting holes 8 are opened on the fixing frame). In this embodiment, the mounting holes 8 on the reinforcing plate 4 facilitate the direct installation of lighting equipment on the reinforcing plate 4 by workers, without the need to open additional holes for installing lighting equipment or fix support devices for installing lighting equipment. This not only reduces the construction cost of urban rail transit and the workload of workers, but also speeds up the construction progress of urban rail transit to a certain extent. Among them, the front top of the support plate 12 is provided with through holes corresponding to the threaded rods.

[0027] The left and right sides of the reinforcing plate 4 are both fixed with rearward-facing connecting grooves 3. The movable ends of the two support rods 2 are both fixed with inserts 14, and the two inserts 14 are respectively inserted into the corresponding connecting grooves 3. The rear side wall of the lower end of the reinforcing plate 4 is provided with a slot. The movable end of the connecting plate 5 is also fixed with inserts 14, and the inserts 14 on the connecting plate 5 are inserted into the slots. In this embodiment, the reinforcing plate 4, the support plate 12, the support rods 2 and the connecting plate 5 can be connected into a whole through the "+" shaped mounting plate. Thus, the reinforcing plate 4 and the connecting plate 5 can be used to support the support plate 12 and the support rods 2, thereby improving the load-bearing capacity of the device for the cable 9. The support rods 2 can also be used to improve the lateral anti-interference strength of the device, thereby improving the stability of the device. At the same time, since the reinforcing plate 4, the support plate 12, the support rods 2 and the connecting plate 5 are all detachably connected, the support rods 2 can also fix the support base 13 to increase the number of cables 9 supported by the device.

[0028] like Figure 1 and Figure 2 As shown, bolts 6 are installed on the front sidewalls of the connecting groove 3 and the reinforcing plate 4 to improve the stability of the connection between the support rod 2 and the connecting plate 5 and the reinforcing plate 4. In this embodiment, the support rod 2 and the connecting plate 5 are firmly fixed to the reinforcing plate 4 by the bolts 6, thereby further improving the stability of the device. The front sidewall of the lower end of the reinforcing plate 4 and the front sidewall of the connecting groove 3 are provided with insertion holes for the rod part of the bolt 6 to enter the slot. The front sidewall of each insert block 14 is provided with a threaded hole for the bolt 6 to enter and to be threadedly engaged with it.

[0029] In this embodiment, the mounting plate is first fixed to the wall or frame on both sides of the track using expansion screws and fixing holes 7. Then, the cable 9 is placed into the arc-shaped groove of the support base 13 and the arc-shaped rod 15 is pressed to make the limiting rod 16 snap into the appropriate limiting groove. Next, the threaded rod at the top of the reinforcing plate 4 is passed through the support plate 12 and the nut 10 is screwed on. Then, the insert 14 on the support rod 2 is inserted into the slot in the corresponding connecting groove 3, and the insert 14 on the connecting plate 5 is inserted into the slot on the rear side wall of the reinforcing plate 4. Finally, the bolt 6 is screwed on to firmly fix the support rod 2 and the connecting plate 5 to the reinforcing plate 4.

[0030] Example 2

[0031] This embodiment further illustrates the technology. The front sidewall of the connecting plate 5 is also uniformly provided with a plurality of mounting holes 8 for installing lighting equipment, such as... Figure 1 As shown, this embodiment also opens mounting holes 8 on the connecting plate 5, which can increase the number of lighting devices installed and improve the lighting effect. It can also install some lighting devices that cannot adjust the lighting angle, so that they can illuminate the track without adjustment.
