[0026] Some embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0027] The turnout roller device is usually assembled on the roller slide bed below the railway turnout switch point rail, that is, the turnout roller device is usually located between the point rail and the roller slide bed.

[0028] Example The present embodiment provides a turnout roller device and a turnout switch, which can effectively solve the technical problems of the cumbersome roller height adjustment process and slow adjustment speed of the fixed structure turnout roller device in the prior art, and can save the steps of preparing the roller height adjustment sheet of the corresponding height according to the surveying results of different working conditions in the prior art, and can also save the operation of disassembling the entire turnout roller device when performing roller height adjustment maintenance in the prior art. The turnout roller device belongs to the eccentric sleeve adjustment type passenger-dedicated turnout roller device, which can be applied to various high-speed railway turnout systems, especially in the occasions with high requirements for running speed and safety.

[0029] See also Figure 1-Figure 26As shown, the turnout roller device provided in this embodiment includes a first bracket 100, a second bracket 200, a rolling body 300, a first sleeve assembly 400 and a second sleeve assembly 500.

[0030] Along the axial direction of the rolling body 300, the first sleeve assembly 400 and the second sleeve assembly 500 are respectively sleeved on both ends of the rolling body 300 to form a roller assembly; along the axial direction perpendicular to the rolling body 300, the first bracket 100 is connected to at least one roller assembly; Figure 1-Figure 4 The turnout roller device is shown to include two roller assemblies. Figure 7 The turnout roller device is shown to include a roller assembly.

[0031] The first bracket 100 is connected to the second bracket 200 to form a sleeve matching hole 120 for accommodating at least part of the first sleeve assembly 400 and at least part of the second sleeve assembly 500 , and an accommodating cavity 110 for accommodating the rolling body 300 .

[0032] The first sleeve assembly 400 and the second sleeve assembly 500 both use an eccentric sleeve assembly 600; the axis of the eccentric sleeve assembly 600 is not colinear with the axis of the rolling element 300; the eccentric sleeve assembly 600 is configured to be able to rotate and adjust around its own axis, so that the rolling element 300 rotates synchronously with the eccentric sleeve assembly 600, so that part of the rolling element 300 protrudes from the surface of the first bracket 100 away from the second bracket 200. That is, the rolling element 300 rotates synchronously with the eccentric sleeve assembly 600 around the axis of the eccentric sleeve assembly 600, so that part of the rolling element 300 protrudes from the surface of the first bracket 100 away from the second bracket 200. In this embodiment, the first bracket 100 is, for example, located above the second bracket 200. In this embodiment, the eccentric sleeve assembly 600 can be rotated and adjusted so that part of the rolling element 300 reaches a preset height, so as to adapt to different working conditions; wherein the preset height is the distance between the rolling element 300 and the surface of the second bracket 200 away from the first bracket 100.

[0033] The switch roller device described in this embodiment includes a first bracket 100, a second bracket 200, a rolling body 300, a first shaft sleeve assembly 400 and a second shaft sleeve assembly 500. The first shaft sleeve assembly 400 and the second shaft sleeve assembly 500 are respectively sleeved on both ends of the rolling body 300 to form a roller assembly. Since the first shaft sleeve assembly 400 and the second shaft sleeve assembly 500 both adopt an eccentric sleeve assembly 600, when adjusting the height of the rolling body 300, the eccentric sleeve assembly 600 can be rotated to make a part of the rolling body 300 protrude from the surface of the first bracket 100 away from the second bracket 200, thereby realizing rapid adjustment of the height of the rolling body 300, which can effectively avoid the operation of disassembling the entire switch roller device due to the need to replace roller height adjustment plates of different specifications in the prior art, and effectively improve the efficiency of height adjustment of the rolling body 300.

[0041] Optionally, the outer peripheral wall of the sleeve body 611, the outer peripheral wall of the sleeve neck 612 and the outer peripheral wall of the operating portion 616 are coaxially arranged; that is, the axis of the outer peripheral wall of the sleeve body 611, the outer peripheral wall of the sleeve neck 612 and the outer peripheral wall of the operating portion 616 is the axis of the eccentric sleeve assembly 600.
