Description

Technical Field

[0001] The invention relates to the field of electrical wiring of suspended skyrail trains, and in particular to a wiring structure of a novel energy-saving and carbon-reducing suspended skyrail train. Background Art

[0002] Since the suspended skyrail train has the significant advantage of low construction cost, its construction investment is relatively small compared with traditional rail transit. At the same time, the feature of convenient maintenance enables the effective control of the later operating costs, reducing the burden on the operator. Moreover, its small footprint allows it to be flexibly arranged in the city, especially in areas with limited space, which can highlight its advantages. Because of this, the suspended skyrail train is widely used in the field of small and medium-sized rail transit, contributing to the diversified development of urban transportation. At the same time, with the rapid development of railway electrical technology, the market's performance requirements for suspended skyrail trains are increasing. Especially in terms of the carrying capacity of the traction system, it is necessary to have a stronger power output to meet the growing transportation needs. The capacity of the power supply system has also attracted much attention, and it is necessary to ensure that it can provide sufficient power support for the train stably and continuously. In addition, the safety of the signal system's autonomous driving is of paramount importance. Only under the premise of high safety assurance can autonomous driving truly play its advantages.

[0003] However, these developments have also brought some new challenges. As the dimensions of the suspension vehicle bogies and equipment on the roof continue to increase, and their number continues to increase, the already limited effective wiring space for vehicles has become increasingly tight. Under such circumstances, how to ensure the stability of the line under vibration conditions, how to avoid interference between different lines under the requirements of electromagnetic compatibility, and how to strictly follow the railway wiring standards and make good use of the limited space to form an efficient and reasonable vehicle wiring solution have become a key problem that needs to be solved urgently. Summary of the invention

[0004] According to the above-mentioned technical problem that the increasing dimensions of the equipment on the bogie and roof of the suspension vehicle cause interference between the lines, a new wiring structure for energy-saving and carbon-reducing skyrail suspension train is provided. The present invention mainly designs a new bogie wiring structure, which divides the wiring path on the bogie into a high-voltage wiring path and a low-voltage wiring path. First, the electromagnetic interference of the high-voltage line to the low-voltage line is eliminated on the bogie, and then the high-voltage wire harness and the low-voltage wire harness on the bogie are gathered at the front and rear positions on the bogie, and the high-voltage wire harness and the low-voltage wire harness are connected to their respective connectors. Finally, the two wire harnesses are distributed to each electrical component through different wiring paths through the high-voltage connector and the low-voltage connector. This solution solves the problem of bringing together the high and low voltage cables on the wiring path from the bogie junction box to the car body.

[0005] The technical means adopted by the present invention are as follows:

[0006] A wiring structure of a new type of energy-saving and carbon-reducing sky-rail suspension train, comprising: a bogie structure, a wiring board, and a car end wiring clamp;

[0007] The front and rear ends of each car are equipped with the same bogie structure. The high-voltage cable clamp and the low-voltage cable clamp on the bogie are made of special wear-resistant and high-temperature resistant materials to form a laying path for high-voltage and low-voltage cables, and the cable path on the bogie is clearly divided into a high-voltage routing path and a low-voltage routing path;

[0008] Special wiring boards are installed on the skirts on both sides of the top of each car. The edges of the boards are equipped with anti-wear rubber strips. The wiring boards can be removed individually through slide rails with locking devices.

[0009] A special vehicle end line clamp is installed above the soft channel between adjacent vehicles to fix the vehicle end connection line. The inner side of the clamp is equipped with an elastic buffer pad and the clamp is fixed by high-strength fastening bolts.

[0010] Furthermore, the high-voltage wiring harness and the low-voltage wiring harness are respectively converged to their own high-voltage connector and low-voltage connector through different routing paths. Both connectors are installed on the bogie as interfaces for connecting the cables on the roof with the cables on the bogie.

[0011] Furthermore, the cables from the roof to the bogie are respectively converged from the high-voltage side and the low-voltage side of the roof to the corresponding bogie connectors through special connecting rods, thereby achieving the docking of the roof cables and the bogie cables.

[0012] Furthermore, the AC line in the high-voltage wiring harness uses a cable with a shielding layer as a transmission carrier, and the outer layer of the low-voltage wiring harness is covered with a hose with a shielding function.

[0013] Furthermore, the wiring board can be disassembled separately, and the wiring board is divided into two layers, an upper layer and a lower layer.

[0014] Furthermore, on the high-voltage side of the roof, the upper wiring board is used to lay high-voltage power lines, and the lower wiring board is used to lay high-voltage AC lines;

[0015] On the low-voltage side of the roof, the upper wiring board is used to lay low-voltage power lines, and the lower wiring board is used to lay low-voltage signal and communication lines.

[0016] Furthermore, a high- and low-voltage distribution box is provided on the high-voltage side, and a low-voltage distribution box is provided on the low-voltage side. All high-voltage wiring harnesses converge to the high-voltage wiring compartment in the high- and low-voltage distribution box, and all low-voltage wiring harnesses converge to the low-voltage distribution box and the low-voltage wiring compartment in the high- and low-voltage distribution box.

[0017] Furthermore, the low voltage distribution box and the high and low voltage distribution box have openings facing the interior of the passenger compartment, and the cables in the boxes are connected to corresponding equipment in the passenger compartment through the openings.

[0018] Furthermore, the high and low voltage distribution box is an electrical interface between adjacent vehicles, and a special vehicle end wire clamp is arranged above the soft channel between the vehicles to fix the high voltage wire harness and the low voltage wire harness between the two boxes.

[0019] Furthermore, the cables on the roof are fixed with the wiring boards on both sides as carriers and are divided into a high-voltage side and a low-voltage side.

[0023] 3. The present invention provides a new wiring structure for an energy-saving and carbon-reducing skyrail suspended train. The new wiring scheme on the bogie uses a connector to connect the roof cable with the bogie cable, which can directly realize the plugging and unplugging of the cables at both ends, thereby increasing the overall maintainability of the bogie, increasing the convenience of wiring, reducing the weight of the bogie, and fixing the movable cables of the bogie.

[0024] 4. The present invention provides a new type of wiring structure for energy-saving and carbon-reducing skyrail suspended train. The cables on both sides of the car body are laid using the height direction of the car body. The cable laying is convenient and simple. The roof cables are fixed with wire tying plates, which saves space, reduces costs, and reduces the weight of the entire vehicle. It can also strictly distinguish different types of cables among the high-voltage cables and low-voltage cables on the roof, which can facilitate future cable maintenance and reduce electromagnetic interference of the entire vehicle.

[0025] 5. The wiring structure of a new type of energy-saving and carbon-reducing skyrail suspended train provided by the present invention uses an overall layout structure of two distribution boxes on the roof, which can reduce costs, save space, reduce the weight of the vehicle body, and make the wiring on the roof more centralized, making it more convenient for workers to connect and calibrate the lines.

[0026] 6. The wiring structure of a novel energy-saving and carbon-reducing skyrail suspended train provided by the present invention and the wiring scheme at the vehicle end eliminate electromagnetic interference between vehicle-end connections and solve the problems of fixation and friction of vehicle-end connections.

The present invention provides a wiring structure of a novel energy-saving and carbon-reducing sky rail suspension train. The high-voltage wire clamp plate 1 and the low-voltage wire clamp plate 2 are fixed to the bogie 7 through a special wire clamp plate mounting plate 3. The installation position of the high-voltage wire clamp plate 1 gathers the high-voltage wires on the bogie 7 into a Figure 1 and Figure 2 The high-voltage wiring path of the bogie 7 shown in the figure is that the high-voltage cables on the bogie 7 are fixed by the high-voltage wire clamp plate, and form a high-voltage wire harness connected to the high-voltage connector 4. The low-voltage wires on the bogie 7 are gathered into a low-voltage wire harness through the installation position of the low-voltage wire clamp plate 2. Figure 1 and Figure 2 The low-voltage wiring path of the bogie 7 is shown, and the low-voltage cables on the bogie 7 are fixed by low-voltage cable clamps to form low-voltage wiring harnesses connected to the low-voltage connector 5. The high-voltage connector and the low-voltage connector are fixed to the bogie 7 through the connector mounting plate 6. The other ends of the high-voltage connector and the low-voltage connector are connected to the high-voltage wiring harness and the low-voltage wiring harness from the car body. These two wiring harnesses are respectively connected to the high-voltage connector and the low-voltage connector through special connecting rods installed on the car body. This wiring scheme solves the problems of cable laying, electromagnetic interference of the bogie itself, and electromagnetic interference of the connection between the bogie and the car body, and increases the overall maintainability of the bogie, increases the convenience of wiring, and reduces the weight of the bogie.

[0045] Example 2

[0046] like Figures 3 to 5 As shown, the wiring board 8 is installed on the body skirt 10 through the skirt mounting seat 9. The wiring board 8 is divided into upper and lower sides when installed. The wiring board on the upper layer of the high-voltage side is used to bundle the high-voltage power line, and the wiring board on the lower layer of the high-voltage side is used to bundle the high-voltage AC line; the wiring board on the upper layer of the low-voltage side is used to bundle the low-voltage power line, and the wiring board on the lower layer of the low-voltage side is used to bundle the low-voltage signal and communication cables.

The low-voltage cables of the whole vehicle are collected through the low-voltage wiring path to the low-voltage junction box and the high-low voltage special junction box. The bottom of the low-voltage junction box and the high-low voltage special junction box have openings. The cables leading to the passenger compartment are connected to the corresponding electrical equipment in the passenger compartment through the openings. This solution reduces costs, saves space, and reduces the weight of the vehicle body. The wiring of the two junction boxes is more centralized, and it is more convenient for workers to connect and calibrate the wires.
