Description

Technical Field

[0001] This utility model relates to the field of urban rail technology, specifically a rapidly assembled intelligent urban rail trough. Background Technology

[0002] Intelligent cable trays for urban rail transit refer to cable tray systems designed and constructed using modern intelligent technologies. They are typically used for various purposes, including track power supply, communication signal transmission, and wiring for monitoring equipment.

[0003] Existing track troughs are mostly assembled using direct contact welding. Although the welding is relatively stable, it is difficult to disassemble during subsequent maintenance and replacement. Moreover, there is a problem with insufficient connection accuracy during welding, resulting in poor overall aesthetics.

[0004] Therefore, in view of the above-mentioned problems, this technical solution proposes a rapid assembly intelligent urban rail trough. Utility Model Content

[0005] The purpose of this invention is to provide a quick-assembly intelligent urban rail duct to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid-assembly intelligent urban rail trough, comprising a rail trough; both ends of the rail trough are respectively provided with female and male connectors. When assembling adjacent rail troughs, the female and male connectors are inserted and positioned by axially approaching each other, and then fixed with bolts. After the female and male connectors are assembled, the ends of the two sets of rail troughs are accurately aligned and connected, ensuring rapid assembly and disassembly while maintaining aesthetics. The female connector includes two sets of symmetrically distributed V-shaped insertion holes on both sides of the lower end of the rail trough. The male connector includes two sets of V-shaped insertion rods corresponding to the V-shaped insertion holes and oscillating on both sides of the lower end of the rail trough. A positioning spring is elastically connected to the inner side of the swing end of the plug rod. When the positioning spring is in a free state, it controls the ends of the two sets of V-shaped plug rods to be in a static state of outward expansion. When the two sets of V-shaped plug rods are controlled to move towards the V-shaped plug hole, the ends of the V-shaped plug rods gradually swing inward along the inner wall of the V-shaped plug hole until the ends of the V-shaped plug rods are in full contact with the inner end of the V-shaped plug hole. At the same time, an internal threaded hole is opened in the middle of the V-shaped plug hole perpendicular to the depth direction. A swing shaft is opened on the V-shaped plug rod at the position corresponding to the internal threaded hole. After the V-shaped plug rod is inserted into the V-shaped plug hole, a positioning bolt is installed by the internal thread facing the internal threaded hole and the swing shaft, so as to firmly position the V-shaped plug rod in the V-shaped plug hole, thereby stably installing the female plug and the male plug.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: When assembling the track trough, the female and male connectors at both ends of the track trough are inserted into each other by axial approach. During connection, the positioning plate is pre-positioned by inserting into the positioning hole. Then, as the distance gets closer, the V-shaped connector rod is inserted into the corresponding V-shaped connector hole until the V-shaped connector rod is completely inserted into the V-shaped connector hole. Then, the positioning bolt on the outside of the V-shaped connector hole is rotated to pass through the swing shaft into the internal thread hole until it extends into the limiting hole. At this time, the ends of the track trough are accurately contacted and assembled. Attached Figure Description

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-4A rapid-assembly intelligent urban rail trough includes a rail trough 10. Each end of the rail trough 10 is provided with a female connector 11 and a male connector 12. When assembling adjacent rail troughs 10, the female connector 11 and male connector 12 are inserted and positioned axially close together, and then fixed with bolts. After the female connector 11 and male connector 12 are assembled, the ends of the two sets of rail troughs 10 are accurately aligned and connected, ensuring rapid assembly and disassembly while maintaining aesthetics. The female connector 11 includes two sets of symmetrically distributed V-shaped insertion holes 18 on both sides of the lower end of the rail trough 10. The male connector 12 includes two sets of V-shaped insertion rods 19 corresponding to the V-shaped insertion holes 18, oscillating on both sides of the lower end of the rail trough 10. The inner sides of the oscillating ends of the two sets of V-shaped insertion rods 19 are elastically connected. A positioning spring 23 is provided. When the positioning spring 23 is in a free state, it controls the ends of the two sets of V-shaped plug rods 19 to be in a stationary state with their ends extending outward. When the two sets of V-shaped plug rods 19 are controlled to move toward the V-shaped plug hole 18, the ends of the V-shaped plug rods 19 gradually swing inward along the inner wall of the V-shaped plug hole 18 until the ends of the V-shaped plug rods 19 are in full contact with the inner end of the V-shaped plug hole 18. At the same time, an internal threaded hole is opened in the middle of the V-shaped plug hole 18 perpendicular to the depth direction. A swing shaft 22 is opened on the V-shaped plug rod 19 at the position corresponding to the internal threaded hole. After the V-shaped plug rod 19 is inserted into the V-shaped plug hole 18, a positioning bolt 13 is installed with the internal thread facing the internal threaded hole and the swing shaft 22 to securely position the V-shaped plug rod 19 in the V-shaped plug hole 18, thereby stably installing the female plug 11 and the male plug 12.

[0018] In this embodiment of the invention, a nut 14 is installed on the outer end of the positioning bolt 13, and a nut groove is provided on the outer end of the internal threaded hole. When the positioning bolt 13 is rotated to enter the internal threaded hole, the nut 14 is moved into the nut groove.

[0019] The outer end of the nut 14 is provided with a cross-shaped rotating groove, which is used to rotate the nut 14 with the help of an external tool, thereby driving the positioning bolt 13 to move toward the internal threaded hole and the swing shaft 22;

[0020] The end of the V-shaped plug rod 19 away from the V-shaped plug hole 18 is rotatably connected to a swing base plate 21 through a positioning screw hole 20. The swing base plate 21 is fixed on the end wall of the track groove 10. A set of base blocks 17 is fixedly installed between the two swing base plates 21. A positioning hole 16 is opened in the middle of the base block 17. A positioning plate 15 is installed between the V-shaped plug holes 18 corresponding to the positioning hole 16. Before the V-shaped plug rod 19 is inserted into the V-shaped plug hole 18, the positioning plate 15 is pre-positioned with the positioning hole 16 to provide accurate positioning for the connection between the V-shaped plug rod 19 and the V-shaped plug hole 18.

[0021] To ensure that the positioning bolt 13 is inserted into the swing shaft 22 and applies stable axial resistance to the V-shaped plug rod 19, the internal threaded hole extends through the middle of the V-shaped plug hole 18 to the inner side, and a limit hole is opened. The end of the positioning bolt 13 extends into the limit hole, thereby applying stable axial resistance to the V-shaped plug rod 19.

[0022] Two sets of positioning springs 23 are provided and are elastically connected to the upper and lower inner sides of the two sets of V-shaped plug rods 19 in the direction close to the swing base plate 21.

[0023] In one embodiment of the present invention, the positioning plate 15, the base block 17, the positioning screw hole 20, and the swing base plate 21 are all made of the same material as the track groove 10, to ensure that when the whole track vehicle is moved after connection, the resistance and stress at each point will not vary greatly due to the different materials.

[0024] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
