[0002] In an electrified railway system, the high-voltage track, as part of the current loop, plays a crucial role. The current is transmitted from the power supply system through the catenary to the train, and then returns to the substation through the high-voltage track, forming a complete current loop. Therefore, the connection and power supply between high-voltage tracks are the key to realizing this function.

[0003] The currently used connection and power supply devices still have the following problems:

[0004] 1. When connecting, it is necessary to adjust the left and right positions of the high-voltage track, which cannot achieve the rapid installation of the connection structure, reducing the connection efficiency; and the bolt holes are prone to misalignment, which is not conducive to the rapid insertion of bolts.

[0005] 2. The outer wall of the high-voltage track is prone to rust, and it cannot automatically remove the rust on the outer wall of the high-voltage track during connection, affecting the subsequent power connection effect. Summary of the Invention

[0021] 2. When the staff rotates the threaded hollow tube with a hex wrench in the present invention, the rust-removing steel file rotates, which has a frictional effect on the outer wall of the high-voltage track, avoiding rust on the outer wall of the high-voltage track and improving the subsequent power connection effect; the setting of the circular limit shaft limits the sliding range of the first hexagonal shaft, preventing the first hexagonal shaft from falling off the threaded hollow tube.

[0022] 3. When the rust-removing steel file rotates in the present invention, under the action of the chamfer, the rust-removing steel file can squeeze the movable power connection seat to move upward automatically; the setting of a row of limit protrusions enables the movable power connection seat to move automatically following the rust-removing steel file. When the threaded hollow tube rotates to a suitable position, the movable power connection seat is also in the corresponding position, realizing the accurate connection between the return cable and the high-voltage track.

[0044] In the embodiment of the present disclosure, as Figure 1 , Figure 2 and Figure 5 shown, the connection positioning mechanism 200 includes: a connection partition block 201, a circular guide rod 202, and a first connection positioning plate 203; the connection partition block 201 is arranged between two adjacent high-voltage tracks 100; there are two circular guide rods 202 in total, and the two circular guide rods 202 are slidably installed inside the connection partition block 201; the first connection positioning plate 203 is fixedly installed at the rear sides of the two circular guide rods 202; the connection positioning mechanism 200 further includes: a second connection positioning plate 204, an arc-shaped positioning frame 205, and a limit baffle 206; the second connection positioning plate 204 is slidably installed outside the two circular guide rods 202; two groups of bolts are installed on the first connection positioning plate 203 and the second connection positioning plate 204, and the two groups of bolts penetrate through the two high-voltage tracks 100; there are two arc-shaped positioning frames 205 in total, and the two arc-shaped positioning frames 205 are fixedly installed at the bottoms of the first connection positioning plate 203 and the second connection positioning plate 204, and the bottoms of the two arc-shaped positioning frames 205 are in contact with the two high-voltage tracks 100 and the connection partition block 201; the limit baffle 206 is fixedly installed at the front ends of the two circular guide rods 202; the connection partition block 201, the first connection positioning plate 203, the second connection positioning plate 204, and the two arc-shaped positioning frames 205 are all made of insulating materials; the connection positioning mechanism 200 further includes: a movable buffer frame 207 and a spiral spring A 208; the movable buffer frame 207 is slidably installed outside the two circular guide rods 202, and the rear side of the movable buffer frame 207 is in contact with the second connection positioning plate 204; there are two spiral springs A 208 in total, and the two spiral springs A 208 are sleeved outside the two circular guide rods 202, and the two spiral springs A 208 are located between the limit baffle 206 and the movable buffer frame 207;

[0045] The left end of the return cable 600 is fixedly installed on the U-shaped conductive frame 300, and the return cable 600 is also located between the second connection positioning plate 204 and the movable buffer frame 207;

[0046] Its specific functions are as follows: Since the two circular guide rods 202 are slidably installed inside the connection partition block 201, the first connection positioning plate 203 is fixedly installed at the rear sides of the two circular guide rods 202, and the second connection positioning plate 204 is slidably installed outside the two circular guide rods 202. When the staff pulls the first connection positioning plate 203 and the second connection positioning plate 204 outwards, the gap between the first connection positioning plate 203 and the second connection positioning plate 204 becomes larger, which is convenient for the staff to insert the connection partition block 201 between the two high-voltage tracks 100. When the staff connects the high-voltage tracks 100, there is no need to adjust the left and right positions of the high-voltage tracks 100, improving the connection efficiency; Also, since the two helical springs A208 are sleeved outside the two circular guide rods 202, and the two helical springs A208 are located between the limit baffle 206 and the movable buffer frame 207. When the staff releases the first connection positioning plate 203 and the second connection positioning plate 204, the first connection positioning plate 203 and the second connection positioning plate 204 move inwards simultaneously under the action of the two helical springs A208, making the first connection positioning plate 203 and the second connection positioning plate 204 automatically contact the two high-voltage tracks 100, which is beneficial for subsequent installation of bolts;

[0047] In addition, since the two arc-shaped positioning frames 205 are fixedly installed at the bottoms of the first connection positioning plate 203 and the second connection positioning plate 204. When the staff presses the first connection positioning plate 203 and the second connection positioning plate 204 inwards by hand, the bottoms of the two arc-shaped positioning frames 205 contact the two high-voltage tracks 100 and the connection partition block 201, ensuring that the two high-voltage tracks 100 and the connection partition block 201 are in the same straight line, which is beneficial for the bolt holes to coincide and facilitates the insertion of bolts into the first connection positioning plate 203, the two high-voltage tracks 100 and the second connection positioning plate 204; Also, since the left end of the return cable 600 is fixedly installed on the U-shaped conductive frame 300, and the return cable 600 is also located between the second connection positioning plate 204 and the movable buffer frame 207. When the return cable 600 is pulled during installation, the return cable 600 can drive the movable buffer frame 207 to move forward, playing a buffering and protecting role; After the return cable 600 is pulled, the two helical springs A208 can drive the return cable 600 to reset backwards, avoiding the detachment of the connection between the return cable 600 and the U-shaped conductive frame 300.

[0048] In the embodiments of the present disclosure, such as Figure 6 and Figure 7As shown in the figure, the rust removal mechanism 400 includes a threaded hollow tube 401, a first hexagonal shaft 402, and a circular limiting shaft 403. The threaded hollow tube 401 is threadedly connected to the U-shaped conductive frame 300. The first hexagonal shaft 402 is slidably installed inside the threaded hollow tube 401. The circular limiting shaft 403 is fixedly installed inside the first hexagonal shaft 402 and is also slidably connected to the first hexagonal shaft 402. The rust removal mechanism 400 further includes a rust removal file 404 and a helical spring B405. The rust removal file 404 is fixedly installed on the rear side of the first hexagonal shaft 402 and is also elastically in contact with the left high-voltage track 100. The helical spring B405 is sleeved outside the threaded hollow tube 401 and the first hexagonal shaft 402, and the helical spring B405 is located between the U-shaped conductive frame 300 and the rust removal file 404.

[0049] Its specific function is as follows: Since the threaded hollow tube 401 is threadedly connected to the U-shaped conductive frame 300, the rust removal file 404 is fixedly installed on the rear side of the first hexagonal shaft 402, and the helical spring B405 is located between the U-shaped conductive frame 300 and the rust removal file 404. When the staff rotates the threaded hollow tube 401 with a hex wrench, the rust removal file 404 rotates, which plays a frictional role on the outer wall of the high-voltage track 100, avoiding rust on the outer wall of the high-voltage track 100 and improving the subsequent power connection effect. Also, since the circular limiting shaft 403 is fixedly installed inside the first hexagonal shaft 402 and is also slidably connected to the first hexagonal shaft 402, it plays a limiting role on the sliding range of the first hexagonal shaft 402, avoiding the first hexagonal shaft 402 from falling off the threaded hollow tube 401.

[0050] In the embodiment of the present disclosure, as Figure 8 and Figure 9 shown, the movable power connection mechanism 500 includes a second hexagonal shaft 501, a movable power connection seat 502, and a helical spring C503. The second hexagonal shaft 501 is slidably installed on the U-shaped conductive frame 300. The movable power connection seat 502 is fixedly installed on the rear side of the second hexagonal shaft 501 and is also slidably connected to the rust removal file 404. The helical spring C503 is sleeved outside the second hexagonal shaft 501, and the helical spring C503 is located between the U-shaped conductive frame 300 and the movable power connection seat 502. The rear end of the movable power connection seat 502 is provided with a chamfer, and the length of the chamfer is greater than the thickness of the rust removal file 404. A row of limiting protrusions 5021 is fixedly installed on the movable power connection seat 502, and there is a gap between the row of limiting protrusions 5021 and the rust removal file 404.

[0051] Its specific function is as follows: Since a chamfer is provided at the rear end of the movable power connection socket 502, and the length of the chamfer is greater than the thickness of the rust removal steel file 404, and the helical spring C503 is located between the U-shaped conductive frame 300 and the movable power connection socket 502, when the rust removal steel file 404 rotates, under the action of the chamfer, the rust removal steel file 404 can squeeze the movable power connection socket 502 to automatically move upward; also, since a row of limit protrusions 5021 are fixedly installed on the movable power connection socket 502, and there is a gap between the row of limit protrusions 5021 and the rust removal steel file 404, the movable power connection socket 502 can move automatically following the rust removal steel file 404. When the threaded hollow tube 401 rotates to a suitable position, the movable power connection socket 502 is also in the corresponding position, achieving the accurate connection between the return cable 600 and the high-voltage track 100.

[0052] Specific usage method and function of this embodiment:

[0053] When the present invention is in use, first, the staff member pulls the first connection positioning plate 203 and the second connection positioning plate 204 outwards. At this time, the gap between the first connection positioning plate 203 and the second connection positioning plate 204 becomes larger, facilitating the staff to insert the connection separation block 201 between the two high-voltage tracks 100. When the staff connects the high-voltage tracks 100, there is no need to adjust the left and right positions of the high-voltage tracks 100, improving the connection efficiency. Then the staff releases the first connection positioning plate 203 and the second connection positioning plate 204. At this time, the first connection positioning plate 203 and the second connection positioning plate 204 move inwards simultaneously under the action of the two spiral springs A208, enabling the first connection positioning plate 203 and the second connection positioning plate 204 to automatically contact the two high-voltage tracks 100, which is beneficial for subsequent installation of bolts. After that, the staff presses the first connection positioning plate 203 and the second connection positioning plate 204 inwards. At this time, the bottoms of the two arc-shaped positioning frames 205 contact the two high-voltage tracks 100 and the connection separation block 201, ensuring that the two high-voltage tracks 100 and the connection separation block 201 are in the same straight line, which is beneficial for the coincidence of bolt holes and facilitates the insertion of bolts into the first connection positioning plate 203, the two high-voltage tracks 100, and the second connection positioning plate 204. Then the staff fixedly installs the left end of the return cable 600 on the U-shaped conductive frame 300, and then passes the return cable 600 through the space between the second connection positioning plate 204 and the movable buffer frame 207. When the return cable 600 is pulled during the installation process, the return cable 600 can drive the movable buffer frame 207 to move forward, playing a buffering and protecting role. After the return cable 600 is pulled, the two spiral springs A208 can drive the return cable 600 to reset backward, preventing the connection between the return cable 600 and the U-shaped conductive frame 300 from falling off. Then the staff rotates the two threaded hollow tubes 401 with a hexagonal wrench. At this time, the two rust-removing steel files 404 rotate, exerting a frictional effect on the outer wall of the high-voltage track 100, avoiding rust on the outer wall of the high-voltage track 100 and improving the subsequent power connection effect. The setting of the two circular limit shafts 403 limits the sliding range of the two first hexagonal shafts 402, preventing the two first hexagonal shafts 402 from falling off the two threaded hollow tubes 401. When the two rust-removing steel files 404 rotate, under the action of the chamfer, the two rust-removing steel files 404 can squeeze the two movable power connection seats 502 to move upwards automatically. The setting of the two rows of limit protrusions 5021 enables the two movable power connection seats 502 to move automatically following the two rust-removing steel files 404. When the two threaded hollow tubes 401 rotate to the appropriate positions, the two movable power connection seats 502 are also in the corresponding positions, realizing the accurate connection between the return cable 600 and the high-voltage track 100.
