Description

Technical Field

[0001] The present application relates to the field of rail transit technology, and in particular to a force transmission mechanism and a rail system. Background Art

[0002] In order to ensure that the seamless turnout maintains good stability and reliability during service, good force transmission characteristics of the heel of the point rail are one of the key factors. A good force transmission mechanism of the heel of the point rail can not only limit the large expansion and contraction displacement of the point rail, but also maintain the stability of the heel of the point rail structure, ensuring that the rail does not break and the structural parts do not break and fail during the process of temperature force transmission of the rail, especially in the environment of large temperature rise and temperature drop.

[0003] Existing seamless turnouts often use the method of setting fixed force transmission devices between the rails to achieve temperature force transmission. For example, existing seamless turnouts can usually set a set of fixed force transmission devices between the rails. When used in an environment with large temperature rise and temperature drop, two sets of fixed force transmission devices can usually be set. When two sets of force transmission devices are set, sufficient space is required in the turnout structure. Currently, it is only applicable to large-number turnouts of No. 18 and above. For turnouts of No. 12 and below, the turnout structure has a small space and cannot set two sets of force transmission devices.

[0004] Therefore, for turnouts No. 12 and below, if only one set of fixed force transmission devices is set, the force transmission characteristics are usually weak. When used in an environment with large temperature rise and drop, the point rail is prone to large expansion and contraction displacement, resulting in local bending of the rails, damage and failure of structural parts, etc. Summary of the invention

[0094] See also Figures 1 to 30 As shown, in view of the problems that the existing force transmission mechanism in the No. 12 and below turnouts has weak force transmission characteristics, does not meet the use requirements in a large temperature rise and temperature drop environment, has low structural strength, and has poor stability, the present application provides a track system, in which an improved force transmission mechanism is provided, which belongs to the turnout point rail heel end force transmission mechanism. While improving the force transmission characteristics, it is not limited by the turnout structure space, which not only solves the above-mentioned problems existing in the No. 12 and below turnouts, but also can be applied to large number turnouts, and has the advantages of high structural strength and strong stability. In addition to the improved force transmission mechanism mentioned above, the track system also includes matching switch sleepers 7, basic rails 1, point rails 2, etc. The force transmission mechanism provided by the present application can be assembled on the switch sleepers 7, wherein the number of switch sleepers 7 can be two or more, so that the force transmission mechanism can be assembled on two switch sleepers 7. The basic rail 1 and the point rail 2 can both be assembled on the force transmission mechanism.

[0095] Regarding the force transmission mechanism mentioned above, the force transmission mechanism may include a conjoined base member 6, a first force transmission assembly 3, a second force transmission assembly 4, a third force transmission assembly 5, etc. The conjoined base member 6 may be configured to connect the base rail 1 and the point rail 2, for example, the base rail 1 and the point rail 2 are both assembled on the conjoined base member 6. The main function of the conjoined base member 6 is to assemble and connect the base rail 1, the point rail 2, the first force transmission assembly 3, the second force transmission assembly 4, and the third force transmission assembly 5 as a whole, and fix them to two switch sleepers 7 at the same time.

[0096] The first force transmission component 3 is mainly used to be assembled between the base rail 1 and the point rail 2. The first force transmission component 3 includes a first sub-component 31 and a first mother component 32 that can be plugged into each other. The number of the first sub-component 31 and the first mother component 32 can be set to one or more. The first sub-component 31 and the first mother component 32 can be configured to be assembled on the inner side of the base rail 1 and the inner side of the point rail 2, respectively, so that the first force transmission component 3 is assembled between the base rail 1 and the point rail 2.

[0097] The second force transmission component 4 is mainly used for being assembled on the outside of the basic rail 1. The second force transmission component 4 includes a second sub-component 41 and a second mother component 42 which can be plugged into each other. The number of the second sub-component 41 and the second mother component 42 can be set to one or more. The second sub-component 41 and the second mother component 42 can be configured to be assembled on the outside of the basic rail 1 and the conjoined base component 6, respectively, so that the second force transmission component 4 is assembled on the outside of the basic rail 1.

[0098] The third force transmission assembly 5 is mainly used for being assembled on the outer side of the point rail 2. The third force transmission assembly 5 includes a third sub-assembly 51 and a third mother assembly 52 which can be plugged into each other. The number of the third sub-assembly 51 and the third mother assembly 52 can be set to one or more. The third sub-assembly 51 and the third mother assembly 52 can be configured to be assembled on the outer side of the point rail 2 and the conjoined base assembly 6, respectively, so that the third force transmission assembly 5 is assembled on the outer side of the point rail 2.

[0099] As can be seen from the above, the force transmission mechanism is not only equipped with a first force transmission component 3 between the basic rail 1 and the point rail 2, but also equipped with a second force transmission component 4 and a third force transmission component 5 that are force-coordinated with the first force transmission component 3. The second force transmission component 4 is assembled on the outside of the basic rail 1, and the third force transmission component 5 is assembled on the outside of the point rail 2. Thus, a new force structure can be formed between the basic rail 1 and the point rail 2 by the first force transmission component 3, the second force transmission component 4, and the third force transmission component 5. At the same time, a connected base member 6 is also added, and the basic rail 1, the point rail 2, the first force transmission component 3, the second force transmission component 4, and the third force transmission component 5 are assembled and connected as a whole by using the connected base member 6, and are fixed to two switch sleepers 7 at the same time.

[0100] The force transmission mechanism thus formed not only has the characteristics of small structural space, but also has the characteristics of high structural strength, strong force transmission performance and wide adaptability. It can effectively improve the force transmission characteristics of the turnout point rail heel end and improve the stability of the turnout point rail heel end structure.

[0101] The first sub-component 31, the second sub-component 41 and the third sub-component 51 in the first force transmission component 3, the second force transmission component 4 and the third force transmission component 5 can be provided with one or more plug-in protrusions, and the shape of the plug-in protrusions can be set to regular or irregular structures such as columnar or block-shaped according to requirements. At the same time, the first mother component 32, the second mother component 42 and the third mother component 52 in the first force transmission component 3, the second force transmission component 4 and the third force transmission component 5 can be provided with one or more plug-in grooves, and the shape of the plug-in grooves can be set to regular or irregular groove structures such as columnar grooves and block-shaped grooves according to requirements, which are not limited here.

[0102] In one embodiment, the first sub-component 31 is provided with a first plugging protrusion, and the first female component 32 is provided with a first plugging groove. In the working state, the first plugging protrusion of the first sub-component 31 is configured to be plugged and matched with the first plugging groove of the first female component 32. The second sub-component 41 is provided with a second plugging protrusion 411, and the second female component 42 is provided with a second plugging groove 421. In the working state, the second plugging protrusion 411 of the second sub-component 41 is configured to be plugged and matched with the second plugging groove 421 of the second female component 42. The third sub-component 51 is provided with a third plugging protrusion, and the third female component 52 is provided with a third plugging groove. In the working state, the third plugging protrusion of the third sub-component 51 is configured to be plugged and matched with the third plugging groove of the third female component 52.

[0103] Moreover, when the first sub-component 31 and the first mother component 32 of the first force transmission component 3 are plugged into each other, one or more surfaces between the first plug-in protrusion and the first plug-in groove can be set to remain parallel to each other. Maintaining the parallel state all the time can ensure that the first sub-component 31 and the first mother component 32 form a uniform force transmission effect after contacting each other, and maintain the longitudinal transmission of the temperature force between the rails, which can reduce the damage of components caused by the dispersion of the temperature force and further improve the structural stability.

[0104] For the same reason, when the second sub-component 41 and the second female component 42 of the second force transmission component 4 are plugged in and matched with each other, one or more surfaces between the second plugging protrusion 411 and the second plugging groove 421 can also be set to remain parallel to each other. When the third sub-component 51 and the third female component 52 of the third force transmission component 5 are plugged in and matched with each other, one or more surfaces between the third plugging protrusion and the third plugging groove can also be set to remain parallel to each other. No further details are given here.

[0105] In one embodiment, the outer surface of the first plug-in protrusion may include a first bottom surface and two first side surfaces, and the inner wall of the first plug-in groove may include a first bottom groove wall and two first side groove walls, the first bottom surface and the first bottom groove wall are parallel to each other, and the two first side surfaces are respectively parallel to the two first side groove walls.

[0106] In one embodiment, the outer surface of the second plug-in protrusion 411 may include a second bottom surface 413 and two second side surfaces 412, and the inner wall of the second plug-in groove 421 may include a second bottom groove wall 423 and two second side groove walls 422, the second bottom surface 413 and the second bottom groove wall 423 are parallel to each other, and the two second side surfaces 412 are respectively parallel to the two second side groove walls 422.

[0107] In one embodiment, the outer surface of the third plug-in protrusion may include a third bottom surface and two third side surfaces, the inner wall of the third plug-in groove may include a third bottom groove wall and two third side groove walls, the third bottom surface and the third bottom groove wall are parallel to each other, and the two third side surfaces are respectively parallel to the two third side groove walls.

[0108] A first gap 33 may be formed between the first plug-in protrusion and the first plug-in groove, and after the first plug-in protrusion and the first plug-in groove are plugged and assembled with each other, the first gap 33 may be in a gap state with a fixed gap size. In one embodiment, a fixed first longitudinal gap may be set between the first bottom surface and the first bottom groove wall, and two fixed first transverse gaps may be set between the two first side surfaces and the two first side groove walls, respectively, so that the first gap 33 includes the one first longitudinal gap and the two first transverse gaps.

[0109] A second gap 43 can be formed between the second plug-in protrusion 411 and the second plug-in groove 421, and after the second plug-in protrusion 411 and the second plug-in groove 421 are plugged and assembled with each other, the second gap 43 can be in a spaced assembly state in which the gap size can be adjusted as needed. Among them, the second sub-component 41 is fixedly connected to the outer side of the basic rail 1, and the second mother component 42 is movably connected to the connected base component 6. At this time, the second sub-component 41 is stationary relative to the basic rail 1, and the second mother component 42 can move in a three-dimensional space relative to the connected base component 6. When the second mother component 42 moves its spatial position relative to the connected base component 6, it can move its spatial position relative to the second sub-component 41, thereby adjusting the gap size of the above-mentioned second gap 43 based on the movement of the second mother component 42, so that the second gap 43 is in a spaced assembly state in which the gap size can be adjusted as needed.
