Description

Technical Field

[0001] The utility model relates to the technical field of urban rail transit, in particular to the technical field of power cable engineering of a rail transit vehicle and its vehicle-end junction box, and specifically to a device for simulating physical cable wiring after the internal structure scheme of the vehicle-end junction box of a rail transit vehicle is determined. Background Art

[0002] The vehicle-end junction box of urban rail transit vehicles is an important electrical component for electrical connection of adjacent vehicles. The main function of the vehicle-end box of urban rail transit vehicles is to realize the interconnection of vehicle lines between adjacent marshaling groups on the train and the role of internal line shunting breakpoints in the vehicle. The lines of various functional equipment on the vehicle are aggregated to the vehicle-end box, and multiple cables are connected in parallel through terminal blocks in the vehicle-end box. Finally, the cables with reduced number after parallel connection are connected to the adjacent vehicle through the vehicle-end jumper connector. In recent years, due to the continuous development of digital smart trains, the functions of urban rail vehicles are constantly increasing, resulting in an increase in the number of cables used on vehicles; in addition, in order to reduce the weight of the whole vehicle, the external dimensions of the vehicle-end box are also gradually reduced and reduced in weight, which makes the internal wiring scheme of the vehicle-end box face the problem of more cables and more compact space. Therefore, only by improving the efficiency of the use of space in the box can the increasing functional requirements of the vehicle be met, and unreasonable structural layout will not only increase the difficulty and working hours of wiring, but also be unfavorable for later inspection and maintenance. This shows the importance of a reasonable and effective vehicle-end box structure scheme for its wiring.

[0003] At present, the wiring plan for the vehicle-end box is generally determined by the experience of designers and the three-dimensional software simulation wiring method. However, on the one hand, the experience of personnel is subjective and non-replicable, and there is no specific theoretical basis, which poses a great risk. On the other hand, the time cost of the three-dimensional software simulation wiring method is too high, and there is still a large difference in the softness of the software simulation and the actual cable, and it cannot effectively identify the operational difficulty of the actual wiring.

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, a wiring simulation device for a vehicle end box of an urban rail vehicle includes a base 8, a height adjustment frame 1, a corner device 2, a side panel 3, a wire tie rod 4, a wire outlet plate 5, a horizontal adjustment frame 6, and a terminal block 7. The horizontal adjustment frame 6 and the height adjustment frame 1 in a flat structure are both fixed on the base 8. The horizontal adjustment frame 6 arranged horizontally and the height adjustment frame 1 arranged vertically are arranged in an L shape. A plurality of mounting holes arranged in a matrix are provided on the horizontal adjustment frame 6 and the height adjustment frame 1. By using different mounting holes, the positions of the corner device 2, the side panel 3, the wire tie rod 4, the wire outlet plate 5 and the terminal block 7 can be adjusted to simulate the internal structure of the vehicle end box of an urban rail vehicle of different specifications.

[0025] The corner device 2 is installed on the height adjustment frame 1; the side panels 3, the wire tie rods 4, the outlet plate 5 and the terminal block 7 are all installed on the mounting holes of the horizontal adjustment frame 6 by bolts, and can adjust their own positions by replacing the mounting holes connected to them. The two side panels 3 are both vertically arranged and are respectively arranged on the two side edges of the top surface of the horizontal adjustment frame 6. The terminal block 7 is located between the outlet plate 5 and the height adjustment frame 1. Multiple wire tie rods 4 are arranged between the two side panels 3. Multiple first threading holes are opened on the outlet plate 5.

[0026] like Figure 3 As shown, the corner device 2 includes a fixing frame 2-1, a flip frame 2-2 and a threading panel 2-3. The fixing frame 2-1 is hung on the mounting hole of the height adjustment frame by a hook, or fixed to the mounting hole of the height adjustment frame by a bolt. Two mounting plates 2-4 are fixedly arranged on the fixing frame 2-1;

[0027] Ear plates 2-5 are folded and provided on both sides of the flip frame 2-2. The ear plates 2-5 on both sides of the flip frame 2-2 are rotatably connected to the bottoms of the two mounting plates 2-4 respectively through pins. Sector plates 2-6 are integrally formed on the ear plates 2-5 on both sides of the flip frame 2-2. The center of the circle of the sector plate 2-6 coincides with the rotation axis of the flip frame 2-2. The sector plate 2-6 is provided with a plurality of locking through holes 2-6-1 arranged in an arc direction at equal intervals. The two mounting plates 2-4 are provided with connecting holes corresponding to the positions of the locking through holes 2-6-1. The connecting holes on the two mounting plates 2-4 and any one of the locking through holes 2-6-1 on the two sector plates 2-6 are fixed by bolts and nuts respectively.

[0028] A threading panel 2-3 is fixed on the flip frame 2-2; a plurality of second threading holes are provided on the threading panel 2-3. When the bolts and nuts are removed, by rotating the flip frame 2-2, different locking through holes 2-6-1 can be aligned with the connecting holes, thereby adjusting the inclination of the threading panel 2-3 on the flip frame 2-2, so as to simulate a car end box with a line entry structure with different inclination angles. A plurality of scale lines corresponding to each locking through hole 2-6-1 are provided on the sector plate 2-6. A corresponding scale value is provided on the side of each scale line. The scale value is used to indicate the angle between the threading panel 2-3 and the vertical plane when the corresponding locking through hole 2-6-1 is used.

The corner device 2 is used to simulate the incoming wire structure of the vehicle end box; the wire tie rod 4 is used to simulate the wire tie structure of the vehicle end box; the outlet plate 5 is used to simulate the outgoing wire structure of the vehicle end box; and the terminal block 7 is used to simulate the wiring structure of the vehicle end box.

[0030] In the actual car end box, the cables in the car are obliquely introduced into the car end box through the incoming cable structure and connected to the wiring structure. One end of the cable to be led out is connected to the wiring structure, and after being fixed at the binding structure, it is led out through the outgoing cable structure. The led-out cable is connected to the corresponding car end box of another car.

[0031] The working principle of the utility model is as follows:

[0032] According to the size and structure of the designed vehicle end box, adjust the position and posture of the corner device 2, the two side panels 3, the wire tie rods 4, the outlet plate 5, and the terminal block 7 so that their relative position and posture are consistent with the interior of the actual vehicle end box. Use cables to pass through the corner device 2 from the bottom of the fixing frame 2-1, and connect to the terminal block 7 after passing through the threading panel 2-3; fix another set of cables to the wire tie rods 4, connect one end of the cables to the terminal block 7, and then pass the other end through the outlet plate 5. Observe the damage to the cables during installation (such as excessive bending, etc.) and the convenience of the entire operation process to judge the design rationality of the simulated vehicle end box, so as to optimize the internal structure of the simulated vehicle end box.
