Description
Technical Field
[0001] The invention relates to the field of rail expansion and contraction adjusters, and in particular to an emergency reinforcement device for a rail expansion and contraction adjuster. Background Art
[0002] Rail expansion regulator, also known as temperature regulator, is a device for adjusting rail expansion and contraction. Rail expansion regulator is installed on the track, and the expansion and contraction of the track can be adjusted by relative displacement of the point rail or the base rail. It is often used on large-span steel beam bridges, bridgeheads and seamless lines where the expansion and contraction of the rails needs to be adjusted. Rail expansion regulator is a device that keeps the rail gap from changing too much when the rails expand and contract, so as to maintain the smoothness of the line. On large-span railway bridges, especially on suspension bridges, in addition to considering the impact of structural expansion and contraction on the bridge deck, the angular displacement of the structure should also be considered.
[0003] High-speed turnouts and rail expansion and contraction adjusters are key track components that affect driving safety and stability, and are one of the key technologies in high-speed railway construction. On high-speed railways, the probability of rail parts breaking in high-speed turnouts and rail expansion and contraction adjusters is relatively small, but due to the high driving speed, once the rail parts break, it will cause huge harm. Therefore, in the event of an accidental break, an emergency reinforcement device is usually required for emergency reinforcement of the broken part. In actual application, traditional emergency reinforcement devices can only pressurize and fix the broken area as a whole. In the face of different breakage situations, the reinforcement effect of fixing the entire area is poor, and it is not possible to specifically reinforce areas with greater stress. Therefore, we have made improvements to this and proposed an emergency reinforcement device for rail expansion and contraction adjusters. Summary of the invention
[0004] The purpose of the present invention is to provide an emergency reinforcement device for a rail expansion adjuster. By setting a clamping element and a fixing element, the problem that a conventional emergency reinforcement device can only perform regional processing support on the broken area but cannot perform individual reinforcement on a specific area is solved.

[0010] As a preferred technical solution of the present application, the clamping element further includes a reinforcing block, the reinforcing block is fixed to the surface of the stress dispersion arc surface, and an adjustment groove is provided inside the reinforcing block; Wherein, a transverse plate is slidably provided in the adjusting groove.
[0011] As a preferred technical solution of the present application, one side of the transverse plate is provided with an interference element for assembly with the fixed plate.

[0023] See also Figures 1 to 6 As shown, the present invention provides a technical solution: an emergency reinforcement device for a rail expansion and contraction adjuster, comprising a base rail 1 and a point rail 2 that are arranged in close contact with each other, wherein a reinforcement platform 21 is provided on a side of the point rail 2 that is away from the base rail 1, and a clamping element 3 is provided on the surface of the reinforcement platform 21, and a fixing element 4 is provided on the surface of the clamping element 3, wherein the fixing element 4 cooperates with the clamping element 3 to form an emergency reinforcement for the reinforcement platform 21; The surface of the fixing element 4 is also provided with a reinforcing element 5 for cooperating with the pressing element 3, and the reinforcing element 5 can further strengthen the fixing element 4; The pressing element 3 includes a pressing plate 31, and the pressing plate 31 has a side table 310 and a plane table 311, wherein a stress dispersion arc surface 315 is formed at the connection between the side table 310 and the plane table 311; By designing the stress dispersing arc surface 315, when the clamping plate 31 is closely attached to the outer side of the point rail 2 to form a support reinforcement for the fracture, the stress on the clamping plate 31 itself can be dispersed. By evenly distributing the stress on the surface of the side table 310 and the plane table 311, it is avoided that the stress is concentrated at the corner of the connection, which may easily cause the clamping plate 31 to break, thereby ensuring the support reinforcement stability of the device. The fixing element 4 comprises a fixing plate 41, and a pressing portion 42 is extended from the fixing plate 41 toward the pressing plate 31. An embedded groove 312 matching with the pressing portion 42 is formed at the bottom of the flat table 311 at a position corresponding to the pressing portion 42. The fixing element 4 further includes a guide block 43, and a guide groove 313 adapted to the guide block 43 is formed at the bottom of the plane table 311 at a position corresponding to the guide block 43; A fixing sheet 44 is fixed to one side of the fixing plate 41 away from the guide block 43, and a fixing bolt 45 is threadedly penetrated on the surface of the fixing sheet 44; A threaded column 420 is fixed on the surface of the pressing portion 42, and a threaded cap 421 is threadedly passed through the surface of the threaded column 420; The surface of the flat table 311 is provided with an arc-shaped fastening groove 314 for the threaded column 420 to pass through, and the threaded cap 421 is pressed tightly against the top of the arc-shaped fastening groove 314; The pressing element 3 further includes a reinforcing block 32, which is fixed to the surface of the stress dispersion arc surface 315, and an adjusting groove 33 is formed inside the reinforcing block 32; Wherein, a horizontal plate 34 is slidably provided in the adjustment slot 33; One side of the transverse plate 34 is provided with an interference element 5 for assembling with the fixing plate 41; The resisting element 5 comprises a sliding seat 51 slidably mounted on the surface of the fixing plate 41, an adjusting rod 52 threadedly penetrated through the top of the sliding seat 51, and a pushing arm 53 threadedly connected to one end of the adjusting rod 52; One end of the propulsion arm 53 is hinged with an adjustment arm 54, and one end of the adjustment arm 54 away from the end of the propulsion arm 53 is fixed with a universal ball 55, and a connection seat 56 is movably sleeved on the surface of the universal ball 55; A U-shaped seat 57 is fixed to one side of the connecting seat 56, and the U-shaped seat 57 abuts against the surface of the horizontal plate 34; A positioning bolt 58 is threadedly provided on one side of the sliding seat 51. The positioning bolt 58 is rotated so that one end thereof abuts against the surface of the fixing plate 41 to position the sliding seat 51. In actual application, when a fracture occurs somewhere on the base rail 1 and the point rail 2 and emergency reinforcement is required, the embedded groove 312 on the clamping element 3 is adapted and assembled with the flat table 311 on the fixing element 4. At this time, the threaded column 421 on the fixing table 311 will pass through the surface of the arc-shaped fastening groove 314, and then the threaded cap 421 is rotated to be threadedly assembled on the surface of the threaded column 421 and abut against the surface of the clamping plate 31, thereby tightening the connection between the clamping element 3 and the fixing element 4. Then, the fixing bolt 45 is rotated to lock one end of the fixing bolt 45 with the support on the ground. The locked pressing element 3 contacts the surface of the point rail 2 through its upper side platform 310, thereby forming an emergency reinforcement effect on the fracture. At the same time, since a reinforcing block 32 is also provided in the pressing plate 3, the support strength of the stress dispersion arc surface 315 is further improved through the design of the reinforcing block 32, thereby ensuring the firmness of the reinforced part. On the basis of the above emergency reinforcement, the sliding seat 51 can also be slidably adjusted on the surface of the fixed plate 41. After the sliding seat 51 is slid to a suitable position, the positioning bolt 58 is rotated so that one end thereof abuts against the surface of the fixed plate 41 to lock the reinforcing element 5. Then, the height of the cross plate 34 is adjusted inside the adjustment groove 33 so that it can be adaptively adjusted according to the position to be emergency reinforced. Since the universal ball 55 and the connecting seat 56 are movably connected, the adjustment of the cross plate 34 will not be affected. When the cross plate 34 is adjusted to a suitable height, the adjusting rod 52 can be rotated to form a threaded fit with the sliding seat 51. The driven adjusting rod 52 will cause the propulsion arm 53 connected to one end thereof to slide. The propulsion arm 53 will slide along with the movement of the adjusting arm 54, and one end of the adjusting arm 54 will come into contact with the connecting seat 56 through the universal ball 55, so that the U-shaped seat 57 will form a resistance to the cross plate 34, thereby further forming support for the side of the clamping plate 31 and improving the reinforcement effect of the device facing the emergency reinforcement point.

Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
