In some embodiments, the track transportation system includes a main track beam and a plurality of switch track beams, the switch 300 is disposed in front of the main track beam and the plurality of switch track beams, and the slider beam 200 is moved by the slider beam traveling system 100, so that the slider beam 200 can be selectively butted with one of the switch track beams to realize track change.
Referring to fig. 1 and 2, the slider beam walking system 100 may include: a guide rail 10 and a guide wheel carriage 20.
Specifically, the guide wheel carriage 20 can move along the guide rail 10 to move the slider beam 200 along the guide rail 10, and the guide rail 10 plays a role of guiding the slider beam 200 to move between positions where it is butted against different turnout rail beams.
In the related art, the guide wheel carriage does not have an anti-overturning structure, and thus, when a vehicle travels through the slider beam, or the slider beam moves along the guide rail along with the guide wheel carriage, the slider beam may overturn due to unbalanced stress, resulting in serious safety accidents such as derailment of the vehicle.
For example, in the example shown in fig. 1, the slider beam 200 is V-shaped, and when a vehicle travels through the slider beam 200, one side of the V-shaped structure engages with the vehicle and the other side does not engage with the vehicle, which causes the two sides of the V-shaped structure to be unevenly stressed and easily overturn. Of course, the slider beams 200 in the present invention include, but are not limited to, the V-shaped slider beams 200 shown in fig. 1, and other structures of the slider beams 200 can also adopt the slider beam walking system 100 according to the embodiment of the present invention to realize the movement of the slider beams 200 while preventing the overturn accident.
In the present invention, as shown in fig. 2, the guide rail 10 is provided with a stopper portion 11, and the guide wheel carriage 20 includes a vehicle body 21 and a guide wheel body 22, wherein the guide wheel body 22 is provided with a stopper fitting portion 221. When the slider beam 200 moves and the slider beam 200 is located at a certain position, the limiting portion 11 can be matched with the limiting matching portion 221 to limit the guide wheel body 22 and the guide rail 10, prevent the guide wheel body 22 from turning over relative to the guide rail 10, further realize limiting the guide wheel trolley 20, prevent the guide wheel trolley 20 from turning over relative to the guide rail 10, and further prevent the slider beam 200 from overturning relative to the guide rail 10.
It should be noted that, in the present invention, each slider beam 200 may be supported by one slider beam traveling system 100 or may be supported by a plurality of slider beam traveling systems 100. For example, in the example shown in fig. 1, one end (e.g., the front end shown in fig. 1) of the slider beam 200 is supported by the slider beam walking system 100 according to the embodiment of the present invention to move, and the other end (e.g., the rear end shown in fig. 1) of the slider beam 200 is supported by the walking mechanism 400 to move, and the walking mechanism 400 may be the slider beam walking system 100 according to the embodiment of the present invention, or may be the walking mechanism 400 with other structures.
According to the slider beam traveling system 100 of the turnout 300 provided by the embodiment of the invention, the problem that the slider beam 200 is easy to overturn can be effectively solved through the matching of the limit matching part 221 of the guide wheel body 22 and the limit part 11 of the guide rail 10, and the traveling safety performance of a vehicle is obviously improved.
The switch 300 according to an embodiment of the present invention includes the slider beam walking system 100 of the switch 300 according to an embodiment of the present invention. Since the slider beam traveling system 100 of the switch 300 according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the switch 300 according to the embodiment of the present invention can effectively improve the problem that the slider beam 200 is easy to overturn by engaging the position-limiting engaging portion 221 of the guide wheel body 22 with the position-limiting portion 11 of the guide rail 10, thereby significantly improving the safety performance of vehicle traveling.
A rail transit system according to an embodiment of the present invention includes a switch 300 according to an embodiment of the present invention. Since the switch 300 according to the embodiment of the present invention has the above-mentioned beneficial technical effects, the rail transit system according to the embodiment of the present invention can effectively improve the problem that the slider beam 200 is easy to overturn by engaging the limit engaging portion 221 of the guide wheel body 22 with the limit portion 11 of the guide rail 10, thereby significantly improving the safety performance of vehicle driving.
The specific structures of the position-limiting part 11 and the position-limiting matching part 221 are not particularly limited in the present invention. Alternatively, in some embodiments, as shown in fig. 2 and 3, the position-limiting part 11 may be a position-limiting protrusion, the position-limiting matching part 221 may be a position-limiting receiving part, and the position-limiting protrusion may be received in the position-limiting receiving part. When slider roof beam 200 atress is uneven, because the limiting displacement of spacing portion of acceping, spacing arch can't be deviate from by spacing portion of acceping, and then prevents that slider roof beam 200 from taking place to topple, and limit structure is simple, is favorable to reducing the production degree of difficulty and manufacturing cost to it is effectual to prevent toppling.
The limit accommodating portion may be a limit groove, or may have another structure as long as it can cooperate with the limit portion 11 to limit the guide wheel carriage 20.
In other embodiments, as shown in fig. 7, the limiting portion 11 may be a limiting receiving portion, and the limiting engagement portion 221 may be a limiting protrusion, so that the limiting protrusion is received in the limiting receiving portion, so as to achieve the effect of preventing the slider beam 200 from overturning. In other words, one of the limiting part 11 and the limiting matching part 221 is a limiting protrusion, and the other of the limiting part 11 and the limiting matching part 221 is a limiting accommodating part.
According to a further embodiment of the present invention, as shown in fig. 3 to 5, the side surface of the guide rail 10 may be provided with a limiting protrusion, and the two ends of the guide wheel body 22 in the axial direction are respectively a first end and a second end, and the first end is far away from the slider beam 200 compared with the second end. The peripheral wall of the guide wheel body 22 may have a first rim 222, with the first rim 222 being located at the first end. The limiting projection is located between the second end and the first rim 222 in the axial direction of the guide wheel body 22.
Thus, the notch space defined by the first rim 222 and the side circumferential surface of the guide wheel body 22 is formed as a limit accommodating portion, and the limit protrusion is located in the notch space. When the slider beam 200 is unevenly stressed, the limiting protrusion may limit the first wheel edge 222 from a side of the first wheel edge 222 facing the slider beam 200, for example, the first wheel edge 222 may be stopped by the limiting protrusion to prevent the first wheel edge 222 from overturning along with the movement of the slider beam 200.
In some embodiments of the present invention, as shown in fig. 3 and 4, the limiting protrusion may extend along the extending direction of the guide rail 10, the first rim 222 may extend along the circumferential direction of the guide wheel body 22, and the first rim 222 is annular. Therefore, when the slider beam 200 moves or is at any position, the first wheel edge 222 can be matched with the limiting protrusion no matter the guide wheel body 22 is at any rotation angle, and the limiting is easier.
Alternatively, in some embodiments, as shown in fig. 3, the length of the stop protrusion may be equal to the length of the guide rail 10. That is, the stopper protrusion may extend from one end of the guide rail 10 to the other end of the guide rail 10 in the extending direction of the guide rail 10. Therefore, in the process that the slider beam walking system 100 drives the slider beam 200 to move, the limiting protrusions and the limiting accommodating parts can be matched with each other, so that the slider beam 200 is prevented from overturning in the moving process, and the overturning prevention effect is better.
According to some embodiments of the present invention, as shown in fig. 3 and 4, the outer circumferential wall of the guide wheel body 22 may further have a second rim 223, the second rim 223 being located at the second end, and the second rim 223 and the first rim 222 defining a limit receptacle therebetween. In other words, the first rim 222, the second rim 223 and the groove defined by the outer circumferential surface of the guide wheel body 22 are formed as a limit accommodating part, and the limit projection is inserted into the groove.
The limiting projection is located between the second rim 223 and the first rim 222 in the axial direction of the guide wheel body 22. The first wheel edge 222 and the second wheel edge 223 can limit the limiting protrusion from two sides of the limiting protrusion, for example, when the stress on the slider beam 200 is unbalanced, at least one of the first wheel edge 222 and the second wheel edge 223 can be stopped by the limiting protrusion to prevent the limiting protrusion from coming off from the limiting accommodating part, so that the slider beam 200 can be prevented from overturning from different directions, and the overturning prevention effect is improved.
Further, as shown in fig. 3 and 4, the second rim 223 may extend along the circumferential direction of the guide wheel body 22, and the second rim 223 is annular. Therefore, when the slider beam 200 moves or is at any position, the second wheel edge 223 can be matched with the limiting protrusion no matter the guide wheel body 22 is at any rotation angle, and the limiting is easier. Or in the embodiment where the extension length of the limiting protrusion is the same as that of the guide rail 10, the second wheel edge 223 can always play a role in preventing overturning during the movement of the slider beam 200, so that the overturning preventing effect is improved.
According to other embodiments of the present invention, as shown in fig. 7, the outer circumferential surface of the guide wheel body 22 may be provided with a limiting protrusion, i.e. the limiting engagement portion is a limiting protrusion. The side surface of the guide rail 10 is provided with a first protrusion 113 and a second protrusion 114, the first protrusion 113 and the second protrusion 114 are arranged at intervals along the axial direction of the guide wheel body 22, and the limiting protrusion may be located between the first protrusion 113 and the second protrusion 114 in the axial direction of the guide wheel body 22.
In other words, the first protrusion 113, the second protrusion 114, and the groove defined by the side surface of the guide rail 10 are formed as a limit receptacle part into which the limit protrusion is inserted. When the stress of the slider beam 200 is unbalanced, at least one of the first protrusion 113 and the second protrusion 114 can stop with the limiting protrusion to prevent the limiting protrusion from coming off from the limiting groove, so that the slider beam 200 can be prevented from overturning from different directions, and the overturning prevention effect is improved.
According to some embodiments of the present invention, as shown in fig. 3 and 7, the guide rail 10 has a first side (e.g., a front side shown in fig. 3 and 7) and a second side (e.g., a back side shown in fig. 3 and 7) opposite to each other, the plurality of limiting portions 11 are plural, and the plurality of limiting portions 11 include a first limiting portion 111 and a second limiting portion 112, wherein the first limiting portion 111 is disposed on the first side, and the second limiting portion 112 is disposed on the second side. The plurality of guide wheel bodies 22 are provided, at least one of the plurality of guide wheel bodies 22 is located on a first side, and at least one of the plurality of guide wheel bodies 22 is located on a second side.
Therefore, the guide wheel bodies 22 can guide the guide wheel trolleys 20 from the two sides of the guide rail 10, so that the guide wheel trolleys 20 can better move along the guide rail 10, the guiding effect is better, the guide wheel bodies 22 can limit the guide wheel trolleys 20 from the two sides of the guide rail 10, the guide wheel trolleys 20 can be prevented from being turned over from the first side of the guide rail 10, the guide wheel trolleys 20 can be prevented from being turned over from the second side of the guide rail 10, and the sliding block beams 200 can be prevented from being turned over from the first side and the second side of the guide rail 10.

When the vehicle passes, the local stress of the guide wheel body is overlarge, and parts for installing and fixing the guide wheel body are basically welded parts, so that local welding seams are easy to crack, and the structural stability is influenced. And the friction between the guide wheel body and the guide rail is increased, and simultaneously, the vibration and the noise are also increased, so that the normal operation of the guide wheel trolley is influenced.
