[0031] In the switch machine installation device of the present embodiment, one end of the point rail connecting rod 1 is fixedly connected to the point rail 100, one end of the spherical bearing 3 is connected to the action rod 201 of the switch machine 200 through the joint iron 2, the point rail connecting rod 1 and the spherical bearing 3 are connected through the lost motion mechanism 4, the lost motion nut sleeve 41 of the lost motion mechanism 4 is slidably connected with the lost motion joint 42, and a limiting boss for abutting against the end face of the lost motion joint 42 is arranged on the lost motion nut sleeve 41, and the lost motion range W between the lost motion nut sleeve 41 and the lost motion joint 42 can be adjusted by adjusting the position of the lost motion nut sleeve 41 on the point rail connecting rod 1 and / or the position of the lost motion joint 42 on the spherical bearing 3; Figure 7 As shown, when the switch machine installation device of this embodiment is used for a turnout with a large travel, the idle motion nut sleeve 41 is adjusted to the right and / or the idle motion joint 42 is adjusted to the left, so that the idle motion W1 is reduced; Figure 8 As shown, when the switch machine installation device of this embodiment is used for a turnout with a small stroke, the idle nut sleeve 41 is adjusted to the left and / or the idle joint 42 is adjusted to the right, so that the idle stroke W2 is increased; thereby adapting to turnouts with different strokes of 40-70mm and meeting the needs of different engineering projects, the joint bearing 3 is rotatably connected with the joint iron 2, and can adapt to the creeping and up and down jumping of the point rail.

[0032] In this embodiment, the point rail connecting rod 1 is provided with an anti-rotation groove 11 arranged along its axial direction, and a notch 411 arranged along its radial direction is provided on one end of the lost motion nut sleeve 41 away from the lost motion joint 42. The lost motion mechanism 4 also includes an anti-loosening nut sleeve 43 screwed on the point rail connecting rod 1 and an anti-loosening retaining ring 44 sleeved on the point rail connecting rod 1. The inner circumference of the anti-loosening retaining ring 44 is provided with a first clamping block adapted to the anti-rotation groove 11, and the anti-loosening retaining ring 44 is provided with a first clamping block adapted to the notch 411. 1, the anti-loosening ring 44 is sleeved on the point rail connecting rod 1, and its self-rotation is limited by the first clamping block and the anti-rotation groove 11.

Optionally, the nut 13 is waist-shaped, and a limiting groove that matches the nut 13 is opened on the point rail 100 to prevent the point rail connecting rod 1 from rotating. Optionally, there are two second nuts 14, which can ensure that the point rail 100 is fixedly connected to the point rail connecting rod 1 and prevent it from loosening.
