In other words, the train's current collector shoes are not connected to the contact rail and cannot obtain current, resulting in frequent power outages and reduced lifespan of internal train components.

[0044] Preferably, the pressure dispersion unit includes: a pressure-bearing sleeve 22, the top of which is fixedly connected to the bottom of the secondary pressure support plate 21, and a connecting spring 23 is provided inside the pressure-bearing sleeve 22; one end of a first connecting rod 24 extends movably into the pressure-bearing sleeve 22 and is fixedly connected to the connecting spring 23; the other end of the first connecting rod 24 is fixedly connected to a limiting slide sleeve 28; a fixing post 27 is fixedly connected to a U-shaped frame 42, and a guide slide rod 271 is fixedly connected to the fixing post 27; the limiting slide sleeve 28 is movably sleeved on the outer wall of the guide slide rod 271; one end of a second connecting rod 25 is fixedly connected to a tertiary pressure support plate 26; and the third... The other end of the second connecting rod 25 movably passes through the guide slide rod 271 and is fixedly connected. The connecting spring 29 is sleeved on the outer wall of the second connecting rod 25, and both ends of the connecting spring 29 are respectively fixedly connected to the guide slide rod 271. One end of the connecting piece 32 is movably connected to the fourth-level pressure support plate 34, and the other end of the connecting piece 32 is movably located in the limiting slide block 35. The connecting piece 32 has a guide slide groove 31. One end of the third connecting rod 30 is fixedly connected to the limiting slide sleeve 28, and the other end of the third connecting rod 30 is movably connected to the guide slide groove 31 through the guide post 33. The limiting slide block 35 is fixedly connected to the U-shaped frame 42.

[0045] Preferably, the second fixed column 38 is fixedly connected to the U-shaped frame 42, the gear 39 is rotatably connected to the second fixed column 38, the T-shaped support column 20 is provided with several sets of tooth blocks 37 on the side near the second fixed column 38, and the several sets of tooth blocks 37 mesh with the gear 39, the U-shaped end of the U-shaped frame 42 is provided with a guide groove 43, the support column 45 is slidably connected to the guide groove 43 through the guide rod 44, and the support column 45 is provided with several sets of tooth blocks 46 on the side near the second fixed column 38, and the several sets of tooth blocks 46 mesh with the gear 39, the rubber plate 41 is connected to the top of the support column 45 through the connecting spring 40.

[0046] The working principle and beneficial effects of the above technical solution are as follows: After the progressively widened contact rail 1 and the turnout switching contact rail 2 are fixed together by the connecting component 3, the primary pressure support plate 18 in the auxiliary pressure relief device 17 will just abut against the rail surfaces of both. When the subway travels over the progressively widened contact rail 1 and the turnout switching contact rail 2, the primary pressure support plate 18 will be subjected to vibration and pressure. At this time, the primary pressure support plate 18 will initially buffer the pressure and then transfer it to the secondary pressure support plate 21. 1. The pressure-bearing sleeve 22 compresses the connecting spring 23 and abuts against the third-level pressure support plate 26. The connecting spring 23, through the first connecting rod 24, causes the limiting sleeve 28 to tend to slide along the outer wall of the guide slide rod 271. At this time, the third-level pressure support plate 26, through the second connecting rod 25, pushes the fourth-level pressure support plate 34 downward and stretches the connecting spring 29. When the fourth-level pressure support plate 34 presses down, it pushes the two sets of connecting parts 32 to move away from each other along the limiting slide 35. At this time, the guide post 33 moves along the guide groove 31. The movement provides an upward thrust to the third link 30, causing the limiting sleeve 28 to tend to slide along the outer wall of the guide slide rod 271. This counteracts the tendency of the first link 24 to drive the limiting sleeve 28 to slide along the outer wall of the guide slide rod 271. In this way, the pressure dispersion unit can disperse and maintain a dynamic balance between the vibration force and pressure from the first-stage pressure support plate 18. When the pressure is too high, the T-shaped support column 20 will drive the gear 39 to rotate through the tooth block 37 when it presses down. The gear 39 will then drive the gear through the tooth block 46. The moving support column 45 slides along the guide groove 43. At this time, the T-shaped support column 20 and the support column 45 move in opposite directions. The rubber plate 41 will abut against the primary pressure support plate 18 and play a certain blocking and supporting role. By setting the auxiliary pressure relief device 17, the vibration force and pressure can be dynamically adjusted when the subway runs over the progressively widened contact rail 1 and the turnout conversion contact rail 2, so as to better protect the joint of the widened contact rail 1 and the turnout conversion contact rail 2 and prevent the widened contact rail 1 and the turnout conversion contact rail 2 from breaking.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
