Description

Switch structure and track system

Technical Field

The application relates to the technical field of rails, in particular to a turnout structure and a rail system.

Background

The turnout structure is an important device in rail transit and is mainly used for vehicle line changing. For example, at a vehicle stop station, a car crash, or a factory, a change of line through a switch structure is required.

At present, in novel rail transit turnouts such as magnetic levitation, straddling type, suspension type and the like, side lines of the turnout are straight line fitting curves, so that fold lines still exist in the turnout beam structure. The speed of the vehicle will be reduced when the vehicle passes through, as in the existing magnetic levitation lines, the linear position speed of the turnout can reach the highest design speed of the line, but the lateral line crossing speed of the vehicle is not more than 25km/h. If the structure of the turnout is not adopted, instead of the straight curved turnout, the prior art has a translational turnout, namely, the main body structure is composed of a section of straight beam and a section of curved beam, and the structure has higher lateral line passing speed of a vehicle although no broken line, but the area of the turnout is larger, and the turnout cost is higher.

Therefore, the switch structure cannot meet a vehicle having a relatively high traveling speed, for example: magnetic levitation vehicles.

Disclosure of Invention

The utility model provides a turnout structure and a track system, which are used for solving the problem that the highest speed of a lateral line in the turnout structure for allowing running is low.

In one aspect, the present application provides a switch structure. The turnout structure comprises a turnout beam, a first fixed end beam, a second fixed end beam and a third fixed end beam. The first end of switch roof beam links to each other with first stiff end roof beam rotation, and the second end of switch roof beam links to each other with the rotation of second stiff end roof beam, and the relative first stiff end roof beam of switch roof beam and second stiff end roof beam rotate between first position and second position. The turnout beam comprises a first sub-beam and a second sub-beam connected with the first sub-beam. Under the condition that the turnout beam rotates to the first position, the first end of the first sub beam is communicated with the first fixed end beam, and the second end of the first sub beam is communicated with the second fixed end beam. Under the condition that the turnout beam rotates to the second position, the first end of the second sub-beam is communicated with the first fixed end beam, and the second end of the second sub-beam is communicated with the third fixed end beam.

In the switch structure provided by the above, the first sub-beam and the second sub-beam are independently arranged. For this purpose, the curvature of the first sub Liang Huodi two sub beams may be set as desired. And, during the operation of the switch structure, the bending radian of the first sub Liang Huodi two sub beams is kept unchanged. Therefore, in the switch structure provided above, the side beam does not need to be fitted by the straight beam. That is, the first sub Liang Huodi two sub beams can be provided with corresponding bending radians according to the needs, and further the situation that fold line parts exist in the first sub Liang Huodi two sub beams can be avoided. Therefore, the turnout structure provided by the application is beneficial to improving the highest speed allowed to run in the lateral line, and solves the problem of low highest speed allowed to run in the lateral line in the related art.

In addition, in the above embodiment, the switch beam realizes the switching of the first sub beam and the second sub beam through overturning, thereby being beneficial to reducing the occupied area of the switch structure and reducing the preparation cost of the switch structure.

According to some alternative embodiments, the first sub-beam is a straight beam and the second sub-beam is a curved beam, wherein a first end of the first sub-beam is rotatably connected to the first fixed end beam and a second end of the first sub-beam is rotatably connected to the second fixed end beam. Thus, the preparation difficulty of the turnout beam is reduced. In addition, the weight of the two sides of the first sub-beam is unbalanced, and the turnout Liang Zaidi can be prevented from turning under the action of gravity by only supporting the second sub-beam. In addition, the gravity of the second sub-beam can be used for preventing the second sub-beam from jumping, so that the reliability of the turnout structure is improved.

In some alternative embodiments, the first sub-beam has opposite first and second sides, the first side of the first sub-beam being provided with a first track; the second sub-beam is located on a second side of the first sub-beam, and a second rail is provided on one side of the first sub-beam of the second sub Liang Beili. The first fixed end beam, the second fixed end beam and the third fixed end beam are all provided with rails. Under the condition that the turnout beam rotates to the first position, the first track is communicated with the track on the first fixed end beam and the track on the second fixed end beam respectively. Under the condition that the turnout beam rotates to the second position, the second track is communicated with the track on the first fixed end beam and the track on the third fixed end beam respectively.

The first mount has a first support portion and a second support portion, the first support portion is located at one side of the third fixed end beam of the second fixed end Liang Kaojin, and the second support portion is located at one side of the third fixed end beam of the second fixed end Liang Yuanli. In the case that the switch beam is rotated to the first position, one end of the first fixed end beam of the second sub Liang Yuanli is supported at the second supporting portion. In the case that the switch beam is rotated to the second position, one end of the first fixed end beam of the second sub Liang Yuanli is supported at the first supporting portion.

In the turnout structure provided by the embodiment, under the condition that the turnout beam rotates to the first position or the second position, the first mounting seat can be supported at one end, far away from the first fixed end beam, of the second sub-beam. Thus, the turnout beam is not only beneficial to preventing the turnout beam from rotating, but also beneficial to reducing the stress at the joint of the turnout beam and the second fixed end beam and improving the stability of the turnout beam.

In some alternative embodiments, a first shock absorbing member is provided on the first support portion. Under the condition that the turnout beam rotates to the second position, the first damping piece is located between the first supporting portion and the second sub-beam. Thus, the buffer force can be provided for the second sub-beam through the first shock absorber, so that the second sub-beam is prevented from directly colliding with the first supporting part, and the first supporting part and the second sub-beam are protected. And, it is also beneficial to reduce the sound that the switch beam makes during the switching of the line.

In some alternative embodiments, a second shock absorber is provided on the second support portion, the second shock absorber being located between the second support portion and the second sub-beam in the event that the switch beam is rotated to the first position. Thus, the second sub-beam can be provided with buffering force through the second damping piece so as to avoid the second sub-beam from directly colliding with the second supporting part, and the second supporting part and the second sub-beam are protected. And, it is also beneficial to reduce the sound that the switch beam makes during the switching of the line.

According to some alternative embodiments, the switch structure further comprises a swivel support. The rotary support piece comprises a support outer ring and a support inner ring which is arranged in the support outer ring and connected with the support outer ring in a rotating fit manner. Illustratively, one of the support outer race and the support inner race is coupled to a first end of the switch beam, the other is coupled to a first fixed end beam, and the switch beam is rotatably coupled to the first fixed end beam via a swivel support. Thus, the first end of the switch beam can be rotatably connected to the first fixed end beam by a swivel support so that the switch beam can rotate between a first position and a second position relative to the first fixed end beam.

According to some alternative embodiments, one of the support outer ring and the support inner ring is connected to the second end of the switch beam, the other is connected to the second fixed end beam, and the switch beam is rotatably connected to the second fixed end beam by a swivel support. Thus, the second end of the switch beam can be rotatably connected to the second fixed end beam by the swivel support member such that the switch beam can rotate relative to the second fixed end beam between the first position and the second position.

According to some alternative embodiments, the swivel support further comprises a first rolling member. The first rolling element is disposed between the support outer race and the support inner race. In this way, it is beneficial to reduce the friction between the support outer race and the support inner race.

According to some alternative embodiments, the switch structure further comprises a drive mechanism. The driving mechanism is connected with the turnout beam and drives the turnout beam to rotate between a first position and a second position. Like this, the switch roof beam can rotate under actuating mechanism's effect, relative first fixed end roof beam and second fixed end roof beam, realizes switch structure and trades the line function.

In the related art, in order to increase the highest speed at which a side line is allowed to travel in a switch structure. The turnout structure comprises a linear beam and a side beam, wherein the linear beam and the side beam are arranged side by side, and the fixed end beams at two opposite ends of the linear beam and the side beam can translate. Thus, the turnout structure line changing function is realized by translating the linear beam and the side beam. However, such switch structures occupy a large area. Also, both the straight beam and the side beam are required to have strength to independently bear the weight of the vehicle. The cost of such a switch structure is relatively high.

Aiming at the technical problems, the embodiment of the application provides a turnout structure and a track system. The turnout structure comprises a turnout beam, a first fixed end beam, a second fixed end beam and a third fixed end beam. The switch beam has two sub beams, with two sub Liang Diezhi connected.

In addition, the embodiment can reduce the dimension of the turnout structure in the horizontal direction by the overturning mode, thereby being beneficial to reducing the occupied area of the turnout structure. Also, the two sub Liang Diezhi are provided so that the two sub beams can synchronously bear the weight of the vehicle. For this reason, this embodiment is beneficial for reducing the load carrying capacity of the individual sub-beams and thus for reducing the manufacturing costs of the switch beam.

The following describes the technical scheme of the present application and how the technical scheme of the present application solves the above technical problems in detail with specific embodiments. The following embodiments may be combined with each other, and the same or similar concepts or processes may not be described in detail in some embodiments. Embodiments of the present application will be described below with reference to fig. 1 to 11.

According to some alternative embodiments, the first aspect of the present application provides a switch structure.

Referring to fig. 1 and 3, in some alternative embodiments of the present application, a switch structure includes a switch beam 100, a first fixed end beam 200, a second fixed end beam 300, and a third fixed end beam 400. Illustratively, the first, second, and third fixed end beams 200, 300, 400 are fixedly disposed to the ground. I.e. the first fixed end beam 200, the second fixed end beam 300 and the third fixed end beam 400 do not move relative to the ground.

Referring to fig. 1-3 and 6, in some alternative embodiments, a first end of the switch beam 100 is rotatably coupled to a first fixed end beam 200 and a second end of the switch beam 100 is rotatably coupled to a second fixed end beam 300. Illustratively, the switch beam 100 rotates between a first position and a second position relative to the first fixed end beam 200 and the second fixed end beam 300.

Illustratively, the switch beam 100 and the first fixed end beam 200, and the switch beam 100 and the second fixed end beam 300 may be rotatably connected through shaft holes. Alternatively, the switch beam 100 and the first fixed end beam 200, and the switch beam 100 and the second fixed end beam 300 may be connected by a ball joint.

In some alternative embodiments, the switch beam 100 is rotatable about a first axis relative to the first fixed end beam 200. The switch beam 100 is rotatable relative to the second fixed end beam 300 about a second axis, the first and second axes being collinear.

Referring to fig. 4 and 5, in some alternative embodiments, both the first and second ends of the switch beam 100 are provided with end shafts 130. Illustratively, the end shaft 130 at the first end of the switch beam 100 and the end shaft 130 at the second end of the switch beam 100 are coaxially disposed.

Referring to fig. 1, 3 to 5, the switch beam 100 includes a first sub-beam 110 and a second sub-beam 120 connected to the first sub-beam 110. As shown in fig. 3, in the case where the switch beam 100 is rotated to the first position, the first end of the first sub-beam 110 communicates with the first fixed end beam 200, and the second end of the first sub-beam 110 communicates with the second fixed end beam 300. As shown in fig. 1, in the case where the switch beam 100 is rotated to the second position, the first end of the second sub-beam 120 communicates with the first fixed end beam 200, and the second end of the second sub-beam 120 communicates with the third fixed end beam 400.

The first end of the first sub-beam 110 is in communication with the first fixed end beam 200, that is, the track on the first sub-beam 110 for running the vehicle is in communication with the track on the first fixed end beam 200 for running the vehicle. The second end of the first sub-beam 110 is in communication with the second fixed end beam 300, i.e. the track on the first sub-beam 110 for the vehicle to travel is in communication with the track on the second fixed end beam 300 for the vehicle to travel. The first end of the second sub-beam 120 is in communication with the first fixed end beam 200, i.e. the track on the second sub-beam 120 for the vehicle to travel is in communication with the track on the first fixed end beam 200 for the vehicle to travel. The second sub-beam 120 communicating with the third fixed end beam 400 means: the rails on the second sub-beam 120 for the vehicle to travel are in communication with the rails on the third fixed end beam 400 for the vehicle to travel.

In some alternative embodiments, the switch beam 100 has opposite first and second ends in the direction of extension thereof. Illustratively, the first fixed end beam 200 is located at a first end of the switch beam 100. The second fixed end beam 300 and the third fixed end beam 400 are located at the second end of the switch beam 100.

In this way, in the case where the first fixed end beam 200 communicates with the second fixed end beam 300 through the first sub-beam 110, the vehicle can travel from the first fixed end beam 200 into the second fixed end beam 300 along the first sub-beam 110. Alternatively, the vehicle may travel from the second fixed end beam 300 into the first fixed end beam 200 along the first sub-beam 110. In the case where the first fixed end beam 200 communicates with the third fixed end beam 400 through the second sub-beam 120, the vehicle may travel from the first fixed end beam 200 into the third fixed end beam 400 along the second sub-beam 120. Alternatively, the vehicle may travel from the third fixed end beam 400 into the first fixed end beam 200 along the second sub-beam 120. Thus, the switch structure provided by the above embodiments can implement a vehicle change by rotating the switch beam 100 between the first position and the second position.

In addition, in the switch structure, the first sub-beam 110 and/or the second sub-beam 120 may be configured as a curved beam according to need, so that the curved beam does not need to pass through the straight line Liang Nige during the line changing process. Specifically, in the switch structure provided in the above, the bending radian of the first sub-beam 110 and/or the second sub-beam 120 may be set as required, and the bending radian of the first sub-beam 110 and/or the second sub-beam 120 may remain unchanged during the line switching process. Therefore, the switch structure can solve the problem that the curve of the straight line Liang Nige has a broken line and the highest running speed allowed by the side line of the switch structure is small in the related art. Moreover, the switch beam 100 does not need to move in the horizontal direction during the process of switching the lines, which is beneficial to reducing the occupied area of the switch structure. In some alternative embodiments, the switch structure may be applied to a magnetic levitation switch.

The curve beam and the linear quantity are preset and prepared and molded according to the needs, and the shape and the structure of the curve beam and the linear beam do not need to be changed in the process of changing the line. Therefore, the continuity of the bending deformation of the curved beam can be ensured, and the speed of the vehicle passing through the turnout structure can be improved.

According to some alternative embodiments, as shown in fig. 1, 3-5, the first sub-beam 110 is a straight beam. The second sub-beam 120 is a curved beam. Wherein a first end of the first sub-beam 110 is rotatably coupled to the first fixed end beam 200. The second end of the first sub-beam 110 is rotatably coupled to the second fixed end beam 300.

The second sub-beam 120 is illustratively a rounded or a gentle curve. The second sub-beam 120 is in a circular shape, that is, the curved portion of the second sub-beam 120 is in a circular arc shape. The second sub-beam 120 is gently curved, i.e. the curvature continuity of the second sub-beam 120 increases or decreases along the extension direction of the second sub-beam 120. This is beneficial to prevent the second sub-beam 120 from being folded and to improve the smoothness of the bent portion of the second sub-beam 120.

Of course, in some alternative embodiments, the second sub-beam 120 includes a straight line segment and an arc segment, wherein the straight line segment is tangent to the arc segment. This is beneficial in avoiding fold lines at the junction of the straight line segment and the circular arc segment, and improving the stability of the vehicle passing through the second sub-beam 120.

Illustratively, the first fixed end beam 200 and the second fixed end beam 300 are disposed opposite. In the case that the switch beam 100 is rotated to the first position, the first sub-beam 110 is collinear with the first fixed end beam 200 and the second fixed end beam 300, i.e., the first sub-beam 110 is disposed along the same line as the first fixed end beam 200 and the second fixed end beam 300.

Illustratively, the switch beam 100 is pivotally connected to the first fixed end beam 200 by a first end of the first sub-beam 110. The switch beam 100 is rotatably coupled to the second fixed end beam 300 by a second end of the second sub-beam 120.

In the above embodiment, the first sub-beam 110 is configured as a straight beam, the second sub-beam 120 is configured as a curved beam, and the switch beam 100 is rotatably connected to the first fixed end beam 200 and the second fixed end beam 300 through the first sub-beam 110, so that the stress on both sides of the first sub-beam 110 is uneven. In this way, in the case of a turning of the switch beam 100 into the first position or the second position, the switch beam 100 can be kept horizontal under the support of the foundation structure, and the second sub-beam 120 can also be prevented from being deflected in a direction away from the ground with respect to the first sub-beam 110 by the self-weight of the second sub-beam 120. Thus, this embodiment can prevent the turnout beam 100 from rotating with respect to the first fixed end beam 200 by the self weight of the second sub-beam 120 and the foundation structure supporting the second sub-beam 120.

Referring to fig. 4 and 5, in some alternative embodiments, the end shaft 130 of the first end of the switch beam 100 is disposed at the end of the first sub-beam 110 adjacent to the first fixed end beam 200. The end shaft 130 of the second end of the switch beam 100 is disposed at one end of the first sub-beam 110 near the second fixed end beam 300.

In some alternative embodiments, the support surface of the track provided on the first sub-beam 110 is the first support surface. The support surface of the rail provided on the second sub-beam 120 is a second support surface. Wherein, the bearing surface of track means: a surface supported in the track. The end shafts 130 at both ends of the switch beam 100 are equally spaced from the first and second support surfaces. Wherein, the distance between the end shaft 130 and the first supporting surface is: the distance between the end shaft 130 and the first support surface in a direction perpendicular to the first support surface. The distance of the end shaft 130 from the second support surface is: the distance between the end shaft 130 and the second support surface in a direction perpendicular to the second support surface.

According to some alternative embodiments, the first sub-beam 110 has opposite first and second sides. A first side of the first sub-beam 110 is provided with a first rail. The second sub-beam 120 is located at a second side of the first sub-beam 110, and a side of the second sub-beam 120 facing away from the first sub-beam 110 is provided with a second track. The first, second and third fixed end beams 200, 300 and 400 are provided with rails. In the case of the turnout beam 100 being rotated to the first position, the first rail communicates with the rails on the first fixed end beam 200 and the second fixed end beam 300, respectively. In the case of the turnout beam 100 being rotated to the second position, the second rail communicates with the rails on the first fixed end beam 200 and the third fixed end beam 400, respectively.

Referring to fig. 1, 3-5, in some alternative embodiments, the first sub-beam 110 and the second sub-beam 120 are disposed in a stacked arrangement. Illustratively, an end of the first sub-beam 110 adjacent to the first fixed end beam 200 overlaps an end of the second sub-beam 120 adjacent to the first fixed end beam 200. The end of the second sub-beam 120 remote from the first fixed end beam 200 is bent toward one side of the first sub-beam 110 with respect to the first sub-beam 110.

In the switch structure provided in the above embodiment, both the first sub-beam 110 and the second sub-beam 120 can be stressed during the process of passing the switch beam 100. In this way, the stress of the first sub-beam 110 and the second sub-beam 120 can be reduced, which is beneficial to reducing the manufacturing cost of the first sub-beam 110 and the second sub-beam 120. In addition, the overlapping arrangement of the first sub-beam 110 and the second sub-beam 120 is beneficial to further reduce the size of the switch beam 100 in the direction perpendicular to its extension, and thus the floor space of the switch structure can be reduced.

Referring to fig. 7, in some alternative embodiments, the first sub-beam 110 includes a bottom plate 111, a web 112, and a spacer 113. Illustratively, the first sub-beam 110 includes two webs 112. The two webs 112 are disposed on both sides of the bottom plate 111 in the width direction. Illustratively, both webs 112 are perpendicular to the base plate 111. Illustratively, the two webs 112 form receiving slots with the base plate 111. The partition plates 113 are disposed at intervals along the extending direction of the bottom plate 111. Illustratively, the plate plane of the spacer 113 is perpendicular to the direction of extension of the base plate 111. In an alternative implementation, the spacer 113 is perpendicular to the bottom plate 111.

Referring to fig. 7, in some alternative embodiments, the first sub-beam 110 further includes a top plate 115 and an F-beam disposed on the top plate 115. Wherein, the F-shaped beam means that the cross section in the vertical direction and the extending direction is F-shaped. Illustratively, the top plate 115 is welded to the bottom plate 111 and the web 112 to form a box beam. The F-beam is disposed on the top plate 115.

In some alternative embodiments, the structure of the second sub-beam 120 is similar to the structure of the first sub-beam 110. For this reason, the specific structure of the second sub-beam 120 is not described in detail.

In some alternative embodiments, the first sub-beam 110 and the second sub-beam 120 may be separately prepared, and then the first sub-beam 110 and the second sub-beam 120 may be connected. For example, the first sub-beam 110 and the second sub-beam 120 may be bolted, welded, and/or riveted therebetween.

According to some alternative embodiments, the switch structure further includes a first mount 500, the first mount 500 having a first support 510 and a second support 520. The first support 510 is located at a side of the second fixed end beam 300 close to the third fixed end beam 400, and the second support 520 is located at a side of the second fixed end beam 300 remote from the third fixed end beam 400. In the case that the switch beam 100 is rotated to the first position, one end of the second sub-beam 120, which is remote from the first fixed end beam 200, is supported on the second support 520. In the case that the switch beam 100 is rotated to the second position, one end of the second sub-beam 120, which is far from the first fixed end beam 200, is supported on the first support 510.

In the above embodiment, the first mount 500 may provide support for the second sub-beam 120 of the switch beam 100 in the event that the switch beam 100 is rotated to the first position or the second position, which is beneficial for reducing the stress of the first sub-beam 110.

In addition, when the switch beam 100 rotates to the first position, the second supporting portion 520 of the first mounting seat 500 abuts against the second sub-beam 120, which is beneficial to improving the connection accuracy of the first sub-beam 110 with the first fixed end beam 200 and the second fixed end beam 300. In the case that the switch beam 100 rotates to the second position, the first supporting portion 510 in the first mounting seat 500 abuts against the second sub-beam 120, so that the connection accuracy between the first sub-beam 110 and the first and third fixed end beams 200 and 400 is improved. Thus, this embodiment is beneficial for improving the accuracy of the track interface between the track on the switch beam 100 and the track on the fixed end beam in a switch structure, and for improving the smoothness of the vehicle passing through the switch structure.

Referring to fig. 1 and 3, in some alternative embodiments, the junction of the first sub-beam 110 and the first fixed end beam 200 forms a first support point for the switch beam 100 in the event that the switch beam 100 is rotated to either the first position or the second position. The junction of the first sub-beam 110 and the second fixed end beam 300 forms a second support point for the switch beam 100. The second sub-beam 120 forms a third supporting point with the first supporting portion 510 or the second supporting portion 520. Referring to fig. 1 and 3, the first support point, the second support point, and the third support point are not collinear. Therefore, in the case that the switch beam 100 is rotated to the first position or the second position, the rotation of the switch beam 100 with respect to the first fixed end beam 200 and the second fixed end beam 300 can be prevented by the self weight of the second sub beam 120, and the stability of the switch beam 100 to the first position or the second position can be improved.

Referring to fig. 1, 3 and 8, in accordance with some alternative embodiments, the switch structure further includes a second mount 1000 and a third mount 1100. Wherein the second mount 1000 is used to provide a mounting basis for the second fixed end beam 300 and the third fixed end beam 400. The third mount 1100 is used to provide a mounting foundation for the first fixed end beam 200.

In some alternative embodiments, the first mount 500 may be integrally provided with the second mount 1000. For example, the first mount 500, the second mount 1000, and the third mount 1100 may each be a concrete base.

According to some alternative embodiments, as shown in fig. 1, 3 and 8, the first supporting part 510 is provided with a first shock absorber 511, and the first shock absorber 511 is located between the first supporting part 510 and the second sub-beam 120 in the case that the switch beam 100 is rotated to the second position. The first shock absorbing member 511 may be a shock absorbing elastic member, for example. By way of example, the first shock absorber 511 may be, but is not limited to, a rubber pad.

In the above embodiment, the first shock absorbing member 511 is beneficial to reduce the impact force between the second sub-beam 120 and the first supporting portion 510, so as to protect the second sub-beam 120 and the first mounting seat 500. In addition, the first shock absorbing members 511 are also beneficial in reducing rattle during switch fabric line changes, preventing switch beam 100 from transiting to constraint.

Referring to fig. 1, 3 and 8, according to some alternative embodiments, a second shock absorbing member 521 is provided on the second supporting portion 520, and the second shock absorbing member 521 is located between the second supporting portion 520 and the second sub-beam 120 in the case that the switch beam 100 is rotated to the first position. By way of example, second cushioning member 521 may be, but is not limited to, a rubber pad.

In the above embodiment, the second shock absorbing member 521 is beneficial to reduce the impact force between the second sub-beam 120 and the second supporting portion 520, so as to protect the second sub-beam 120 and the first mounting base 500. In addition, the second damping member 521 is also beneficial in reducing rattle during the switch fabric line change, preventing the switch beam 100 from transiting to bind.

In this way, the switch beam 100 may be rotatably coupled to the first fixed end beam 200 by the rotary support 600. Illustratively, the end shaft 130 of the first end of the switch beam 100 is coupled to a support inner race 620 of the swing support 600. The first fixed end beam 200 is connected to a support outer race 610 of the rotary support 600.

Referring to fig. 9, in some alternative embodiments, the end shaft 130 may be coupled to the support inner race 620 with bolts. There are many ways of connecting the end shaft 130 to the support inner ring 620, such as welding, riveting, for which the embodiment does not limit the specific way of connecting the end shaft 130 to the support inner ring 620.

Similarly, the support outer race 610 and the first fixed end beam 200, or the support outer race 610 and the second fixed end beam 300, may be coupled by, but not limited to, screw fastening. Illustratively, the support outer race 610 and the first fixed end beam 200, or the support outer race 610 and the second fixed end beam 300, may also be welded, riveted.

Referring to fig. 9, in some alternative embodiments, swivel support 600 further comprises a first rolling member 630. Illustratively, the first rolling element 630 is disposed between the support inner race 620 and the support outer race 610.

In some alternative embodiments, the switch structure further includes a drive mechanism 700. The drive mechanism 700 is coupled to the switch beam 100 and the drive mechanism 700 drives the switch beam 100 to rotate between a first position and a second position.

Illustratively, there are many types of drive mechanisms 700, such as a gear mechanism, a chain mechanism, a worm gear mechanism, and the like. For this reason, the present embodiment is not limited to the specific kind of the driving mechanism 700.

In the above embodiment, the driving mechanism 700 may drive the turnout beam 100 to rotate between the first position and the second position relative to the first fixed end beam 200, so as to facilitate automatic line changing of the turnout structure.

In some alternative implementations, as shown in fig. 1, 3, and 10, the drive mechanism 700 includes a base 710, a swivel 720, a worm 730, and a drive 740. Illustratively, base 710 may provide a mounting basis for swivel 720.

In a further alternative embodiment, both swivel member 720 and worm 730 are disposed on base 710, swivel member 720 is in rotational engagement with base 710, and swivel member 720 is coupled to switch beam 100. Rotating member 720 has a tooth structure by which rotating member 720 engages worm 730. The driving member 740 is connected to the worm screw 730, and the driving member 740 drives the switch beam 100 to rotate between the first position and the second position through the worm screw 730 and the rotating member 720.

Illustratively, rotating member 720 has arcuate tooth segments. Alternatively, rotating member 720 is a worm gear. Illustratively, the axis of rotation member 720 is perpendicular to the axis of worm 730. In this embodiment, the driving member 740 is engaged with the rotating member 720 through the worm screw 730, which is beneficial to improve the stability during transmission, and thus, to reduce the vibration of the switch beam 100 during line changing.

According to some alternative embodiments, as shown in fig. 6 and 10, the drive mechanism 700 further comprises a coupling 760. Illustratively, the kinetic energy output shaft of the driver 740 is coupled to the worm 730 through a coupling 760.

In the above embodiment, the coupling 760 not only can realize the transmission between the driving member 740 and the worm screw 730, but also is beneficial to prevent the vibration generated by the driving member 740 from being transmitted to the worm screw 730, thereby improving the stability of the switch structure.

In the above embodiment, the rotation member 720 and the worm 730 are engaged to drive, which is not only beneficial to increasing the maximum output torque of the driving mechanism 700, but also beneficial to improving the reliability of the switch structure by using the engagement of the rotation member 720 and the worm 730 to realize the self-locking of the switch beam 100 when the driving member 740 stops driving.

In some alternative embodiments, base 710 is fixedly mounted to first fixed end beam 200 and/or second fixed end beam 300, and swivel 720 is coupled to switch beam 100. In other alternative examples, the base 710 may also be fixedly disposed to the second mount 1000 and/or the third mount 1100.

Further alternatively, drive member 740 may be, but is not limited to, an internal combustion engine, a hydraulic motor, a servo motor, a gear motor.

In some alternative embodiments, the driver 740 may be a servo motor. Thus, the rotating angle of the turnout beam 100 relative to the first fixed end beam 200 can be controlled by controlling the rotating number of the servo motor, so that the control precision of the turnout structure is improved, and the stability of the vehicle passing through the turnout structure is improved.

In some alternative embodiments, both the first and second ends of the switch beam 100 are provided with a drive mechanism 700. This is beneficial in reducing the load on the drive mechanism 700.

In some alternative embodiments, drive mechanism 700 further includes a second rolling member 750. Illustratively, the second rolling member 750 is disposed between the base 710 and the rotating member 720 to reduce friction between the base 710 and the rotating member 720.

According to some alternative embodiments, as shown in fig. 11, the switch structure further includes a detection device 800 and a controller 900. The detection device 800 is connected to the controller 900. The controller 900 is connected to the driving mechanism 700. The detecting device 800 is used for detecting relative position information of the switch beam 100 relative to the first fixed end beam 200 and the second fixed end beam 300. The controller 900 turns off the driving mechanism 700 based on the relative position information detected by the detecting device 800.

In the switch structure provided in the above embodiment, the controller 900 may determine whether the switch beam 100 rotates to the preset position according to the detection value of the detection device 800, and shut down the driving mechanism 700 when the switch beam 100 rotates to the preset position, so that the switch beam 100 may stay at the preset position. The preset position may be a first position or a second position.

In some alternative embodiments, detection device 800 includes encoder 810. As shown in fig. 10, in some alternative embodiments, an encoder 810 may be provided to the drive mechanism 700. Illustratively, the encoder 810 is coupled to the worm 730 in the drive mechanism 700 to detect the angle of rotation of the worm 730 by the encoder 810.

For example, the controller 900 may determine the angle at which the rotating member 720 is driven, and thus the switch beam 100 is driven relative to the first fixed end beam 200, according to the transmission ratio between the worm 730 and the rotating member 720 and the angle at which the worm 730 is driven. Illustratively, in the case where the initial position of the switch beam 100 is the first position, the switch beam 100 may be rotated 180 ° from the first position to the second position.

Thus, the above-described embodiment can determine whether the switch beam 100 is rotated to the first position or the second position based on the rotation angle of the worm screw 730 detected by the encoder 810, so as to switch the vehicle travel path through the switch structure.

In some alternative embodiments, an encoder 810 may also be provided on the first fixed end beam 200, and the encoder 810 is connected to the switch beam 100 to detect the angle of rotation of the switch beam 100 relative to the first fixed end beam 200 by the encoder 810.

Referring to fig. 8 and 11, in some alternative embodiments, the detection device 800 may include a travel switch 820. In some alternative embodiments, the detection device 800 may include two travel switches 820. One of the two travel switches 820 is disposed on the first support portion 510, and the other is disposed on the second support portion 520.

For example, when the switch beam 100 rotates to the first position, the switch beam 100 triggers the travel switch 820 disposed on the second supporting portion 520, so that the controller 900 can stop the driving mechanism 700 according to the on-off state of the travel switch 820 disposed on the second supporting portion 520, thereby realizing the accurate stopping of the switch beam 100 at the first position.

Under the condition that the switch beam 100 rotates to the second position, the switch beam 100 triggers the travel switch 820 arranged on the first support portion 510, so that the controller 900 can turn off the driving mechanism 700 according to the on-off state of the travel switch 820 arranged on the first support portion 510, and further the switch beam 100 is accurately stopped at the second position.

Accordingly, the above-described embodiment can determine whether the switch beam 100 is rotated to the first position or the second position by the on-off of the travel switch 820 so as to switch the vehicle travel path through the switch structure.

In some alternative embodiments, the detection device 800 includes not only the encoder 810 but also the travel switch 820, which may enable dual detection, thereby advantageously improving the reliability of the switch structure.

Referring to fig. 1, 3 and 11, the control system sends a switch signal in the event that the switch structure switches from the straight position to the curved position. The controller 900 receives the switch signal and controls the driving mechanism 700 to drive the switch beam 100 to rotate relative to the first fixed end beam 200 so that the switch beam 100 can rotate from the first position to the second position.

In some alternative embodiments, referring to fig. 2, with the switch beam 100 in the first position, the switch structure is in a straight position, i.e., the track on the first sub-beam 110 communicates with the track on the first fixed end beam 200 and the track on the second fixed end beam 300. Referring to fig. 1, with the switch beam 100 in the second position, the switch structure is in the curvilinear position, i.e., the track on the second sub-beam 120 communicates with the track on the first fixed end beam 200 and the track on the third fixed end beam 400.

If the information detected by the detection device 800 matches the preset value, the controller 900 turns off the driving mechanism 700, and the switch beam 100 is switched to the curve position. Because the driving mechanism 700 has a self-locking function, and the self-gravity of the switch beam 100 and the self-locking function of the driving mechanism 700 can be relied on after the switch is in place, the switch beam 100 can be ensured to be fixed relative to the first fixed end beam 200 and the second fixed end beam 300 after the switch is in place, so that the stable passing of the vehicle through the switch structure can be ensured.

The principle of switch structure from the curve position to the straight position is similar to the principle of switch structure from the straight position to the curve position. For this reason, this embodiment is not described in detail.

On the other hand, the application also provides a track system. The track system comprises the turnout structure disclosed by the embodiment of the application, and has the same or similar technical effects as the turnout structure. For this reason, this embodiment is not described in detail.

In some alternative embodiments, the track system further comprises a control system. Illustratively, the control system is coupled to the controller 900 in the switch fabric such that the control system can control the switch system switching lines to the controller 900.
