Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of railway turnout, in particular to a long and large point rail displacement supplement device. BACKGROUND

[0002] In the railway turnout project, some larger number turnouts, such as No. 12 turnout, are often required to use one-point traction conversion mode to reduce the purchase cost of switch machine. However, due to the insufficient number of traction points and the long length of the point rail of large number turnout, there is no force acting on the position far away from the traction point, so the end of the close adhesion section of the point rail and the basic rail often appears unqualified close adhesion, and the close adhesion gap far exceeds the railway standard requirement of less than 1mm. In addition, the track gauge of the point rail area often exceeds the standard. The point rail inevitably has internal stress after manufacturing, and it is difficult to maintain the designed curve line type of the turnout under the condition of insufficient traction points, so the curve radius changes naturally, resulting in position deviation, which is called "insufficient displacement", as shown in the accompanying drawings. Figure 11

[0032] As a further solution, the adjustable connecting rod includes an adjustable connecting rod one 1 rotatably connected with the rail bottom of the straight switch rail and an adjustable connecting rod two 2 rotatably connected with the rail bottom of the curved switch rail, and a two-way threaded sleeve 3 is threadedly sleeved on the threaded segments on the opposite sides of the adjustable connecting rod one 1 and the adjustable connecting rod two 2.

[0033] By rotating the two-way threaded sleeve 3, the distance between the adjustable connecting rod one 1 and the adjustable connecting rod two 2 on both sides can be adjusted, thereby adjusting the length of the adjustable connecting rod, facilitating better installation and debugging of the turnout, and the length of the adjustable connecting rod can be finely adjusted to facilitate the adaptation of turnouts with different track gauges.

Through the bidirectional threaded sleeve 3, the length of the connecting assembly is finely adjusted, so that the installation work is facilitated.

[0036] As a further scheme, the elastic assembly comprises spring terminal one 7 and spring terminal two 8, the spring terminal one 7 extends a guide sleeve on one side close to the spring terminal two 8, the spring terminal two 8 extends a guide rod at a corresponding position, the guide rod is slidingly inserted into the guide sleeve, the threaded end of the spring terminal two 8 is threadedly screwed with a flange nut 81, the threaded end of the spring terminal two 8 is also screwed with a locknut 82 for limiting the flange nut 81, the guide sleeve and the guide rod are further sleeved with a connecting spring 9, and the two ends of the connecting spring 9 are respectively abutted against the corresponding sides of the flange nut 81 and the spring terminal one 7.

[0037] By adjusting the tightening amount of the flange nut 81, the pre-compression amount of the connecting spring 9 can be adjusted, and the greater the tightening amount is, the greater the pushing force of the adjustable connecting rod on the point rail is, and vice versa. By increasing the pushing force, the close length of the point rail and the basic rail can be ensured, and the insufficient displacement condition can be prevented. The locknut 82 is arranged to limit the flange nut 81 and prevent the flange nut 81 from loosening.

[0038] As a further scheme, the hinge piece comprises a hinge bolt 14, a flat washer 16 is sleeved on the upper end of the hinge bolt 14, a slotted nut 15 is screwed on the upper end of the hinge bolt 14, a split pin is inserted between the slotted nut 15 and the hinge bolt 14, a pair of insulating washers 12 are sleeved on the hinge bolt 14, and an insulating sleeve 13 is also sleeved on the hinge bolt 14 between the insulating washers 12.
