Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

Referring now to fig. 1-21, an embodiment of an internally guided switch 100 in accordance with a first aspect of the present invention will now be described.

The internally guided switch 100 according to the embodiment of the present invention may be used for a rail transit system, so that the rail transit system provided with the internally guided switch 100 may have the same advantages as the internally guided switch 100. The concept and other configurations of the rail transit system are known to those skilled in the art and will not be described in detail herein, for example, the rail transit system may be a subway system, a light rail system, etc.

Furthermore, it will be appreciated that, for the monorail inner guide track (including the outer track section and the inner guide turnout described later), there are two support edges defining a guide channel therebetween, the train travelling thereon has two support wheels and a guide wheel located between the two support wheels, the two support wheels are respectively supported on the support edges on both sides to travel, and the guide wheel is limited by the two support edges in the guide channel to determine the travelling direction of the train.

When the inner guide switch 100 is used in a rail transit system, the inner guide switch 100 is connected to external track sections, i.e., the switch track section 200, the first branch track section 300, and the second branch track section 400, and the inner guide switch 100 can be switched between the first passage state and the second passage state.

Referring to fig. 2, when the inner-guided switch 100 is switched to assume the first passing state, the inner-guided switch 100 assumes the first guide passage R1 overlapping between the switch section 200 and the first branch section 300 so that a train can pass between the switch section 200 and the first branch section 300.

Referring to fig. 6, when the inner guided switch 100 is switched to assume the second passing state, the inner guided switch 100 assumes the second guide passage R2 overlapping between the switch section 200 and the second branch section 400 so that a train can pass between the switch section 200 and the second branch section 400.

As shown in fig. 1, the inner guided switch 100 may include: a fixed beam 1, a movable beam 2, and a driving device 3 (see fig. 19). Wherein, the fixed beam 1 may include a first edge beam 11, a second edge beam 12 and a middle beam 13, and the movable beam 2 may include a first movable beam 21 and a second movable beam 22.

As shown in fig. 1 and 3, the first side frame 11, the second side frame 12, and the middle frame 13 are disposed at the same height (i.e., the upper surface of the first side frame 11, the upper surface of the second side frame 12, and the upper surface of the middle frame 13 are flush or substantially flush), the middle frame 13 is located on the branching side (the right side as viewed in fig. 1) between the first side frame 11 and the second side frame 12, and the first movable frame 21 and the second movable frame 22 are both located on the branching side (the left side as viewed in fig. 1) of the middle frame 13, that is, at least a majority of the first movable frame 21 is located on the branching side (the left side as viewed in fig. 1) of the middle frame 13, and at least a majority of the second movable frame 22 is located on the branching side (the left side as viewed in fig. 1) of the middle frame 13.

As shown in fig. 1 and 3, the second movable beam 22 is liftable between the first side beam 11 and the middle beam 13, and the first movable beam 21 is liftable between the middle beam 13 and the second side beam 12. Therefore, the first side beam 11, the second movable beam 22, the middle beam 13, the first movable beam 21 and the second side beam 12 are sequentially arranged along the direction perpendicular to the running direction of the train, and the vertical projections of the first side beam 11, the second side beam 12, the middle beam 13, the first movable beam 21 and the second movable beam 22 are not overlapped. The driving device 3 is used for driving the first movable beam 21 and the second movable beam 22 to ascend and descend, that is, the driving device 3 can drive the first movable beam 21 to ascend and descend on the one hand, and the driving device 3 can drive the second movable beam 22 to ascend and descend on the other hand.

As shown in fig. 2 to 5, in the first pass state, the driving device 3 drives the first movable beam 21 to rise to engage with the middle beam 13 at the same height to define a first guide passage R1 between the first side beam and the first side beam 11, and the driving device 3 drives the second movable beam 22 to lower than the first guide passage R1 (the second movable beam 22 is hidden in fig. 2).

That is, in the first passing state, the upper surface of the first movable beam 21 is flush or substantially flush with the upper surfaces of the middle beam 13, the first side beam 11 and the second side beam 12, and at this time, the first side beam 11 serves as one side supporting edge of the first guiding passage R1, the first movable beam 21 and the middle beam 13 are connected as the other side supporting edge of the first guiding passage R1, and the first guiding passage R1 is defined between the two side supporting edges.

Thus, assuming that a train needs to travel from the switch track segment 200 to the first switch track segment 300, the inner guided switch 100 may be switched to the first passing state to present the first guide way R1, so that, when a train travels from the switch track segment 200 to the inner guided switch 100, the guide wheels of the train may enter the first guide way R1 to be guided, one support wheel of the train travels supported on the support side defined by the first side beam 11, and the other support wheel of the train travels supported on the support side defined by the first movable beam 21 and the intermediate beam 13, and the train may smoothly travel to the first switch track segment 300 under the guidance of the first guide way R1. Also, when a train needs to travel from the first branch track segment 300 to the switch track segment 200, the implementation principle is similar and will not be described herein.

As shown in fig. 6 to 9, in the second travel state, the driving device 3 drives the second movable beam 22 to be raised to engage with the middle beam 13 at the same height so as to define a second guide passage R2 between the second side beam 12, and the driving device 3 drives the first movable beam 21 to be lowered to be lower than the second guide passage R2 (the first movable beam 21 is hidden in fig. 7).

That is, in the second passing state, the upper surface of the second movable beam 22 is flush or substantially flush with the upper surface of the middle beam 13, the upper surface of the first side beam 11, and the upper surface of the second side beam 12, and at this time, the second side beam 12 serves as one side supporting edge of the second guiding passage R2, the second movable beam 22 and the middle beam 13 are connected as the other side supporting edge of the second guiding passage R2, and the second guiding passage R2 is defined between the two side supporting edges.

Thus, assuming that a train needs to travel from the switch track segment 200 to the second switch track segment 400, the inner guided switch 100 may be switched to the second travel state to present the second guide way R2, so that, when a train travels from the switch track segment 200 to the inner guided switch 100, the guide wheels of the train may enter the second guide way R2 to be guided, one support wheel of the train travels supported on the support side defined by the second side beam 12, the other support wheel of the train travels supported on the support side defined by the second movable beam 22 and the intermediate beam 13, and the train may smoothly travel to the second switch track segment 400 under the guide of the second guide way R2. Also, when a train needs to travel from the second branch track segment 400 to the switch track segment 200, the implementation principle is similar and will not be described herein.

As another example shown in fig. 24, assuming that there is no intermediate beam 13 between the first movable beam 21 'and the second movable beam 22', in order to ensure that the motions of the first movable beam 21 'and the second movable beam 22' do not interfere, and to ensure that the first movable beam 21 'is seamlessly engaged with the first branch rail segment 300, and the second movable beam 22' is seamlessly engaged with the second branch rail segment 400, only the vertical projection of the first movable beam 21 'and the first branch rail segment 300 is point contact engagement, and the vertical projection of the second movable beam 22' and the second branch rail segment 400 is point contact, however, because the supporting area at the point contact engagement is small and the strength is insufficient, when the supporting wheels of the train run to the point contact engagement position, problems such as bumping, even jamming, etc. are likely to occur.

Compared with the example in the upper section, according to the inner guide type switch 100 of the embodiment of the present invention, by skillfully disposing the middle beam 13 at the branch position between the first movable beam 21 and the second movable beam 22, on one hand, the first movable beam 21 and the second movable beam 22 can be ensured not to interfere with each other during the lifting movement, on the other hand, the first movable beam 21 and the first branch rail segment 300 can be connected through the middle beam 13, and the second movable beam 22 and the second branch rail segment 400 can also be connected through the middle beam 13, so that the connection through the middle beam 13 replaces the "point contact connection" in the upper section, thereby effectively improving the supporting area and the supporting strength of the joint, leading the supporting area of the joint to be enough for the supporting wheels to stably run through, leading the supporting strength of the joint to be reliable, and then the problems that the supporting wheel of the train jolts or even is blocked and stopped when the supporting wheel runs to the joint position can be avoided.

Moreover, according to the inner guide type switch 100 of the embodiment of the present invention, since the first movable beam 21 and the second movable beam 22 can be connected to the same middle beam 13 after being lifted, the middle beam 13 can be connected to the first movable beam 21 as a side supporting edge of the first guide channel R1 to realize the support, and can be connected to the second movable beam 22 as a side supporting edge of the second guide channel R2 to realize the support, so that the structural complexity of the inner guide type switch 100 is greatly simplified, and the inner guide type switch 100 has the advantages of small volume, light weight and low cost.

In addition, because the inner guide type turnout 100 comprises the middle beam 13 positioned on the bifurcation side, when the inner guide type turnout 100 is in butt joint with an external track section, the fixed beam 1 can be completely adopted for butt joint, and the position of direct butt joint of the movable beam 2 and an external track section does not exist. For example, in the example shown in fig. 2, when the inner guided switch 100 is butted against the first branch rail segment 300 and the second branch rail segment 400, the inner guided switch 100 may be completely butted against the first side beam 11, the second side beam 12, and the middle beam 13, and there is no position where the first movable beam 21 and the second movable beam 22 are directly butted against the first branch rail segment 300 and the second branch rail segment 400. Therefore, the reliability of butt joint of the internal guide type turnout 100 and the external track section can be improved on the one hand, and the connection difficulty can be reduced on the other hand.

However, in the other example shown in fig. 24, there are positions where the first movable beam 21 ' and the second movable beam 22 ' are directly butted with the first branch rail segment 300 and the second branch rail segment 400, so that the reliability of butting the inner guide type switch 100 ' with the outer rail segment is insufficient, and the first movable beam 21 ' and the second movable beam 22 ' cannot be effectively supported in a limiting manner, so that the guide channel defined by the first movable beam 21 ' and the second movable beam 22 ' has a poor guide effect.

In short, the inner-guiding type turnout 100 according to the embodiment of the invention has the advantages of simple and ingenious structure, small volume, light weight, convenient switching of the guiding channels, time and labor saving, high connection reliability with the external track segment, low connection difficulty, and capability of ensuring that a train can stably and reliably drive in and out of the inner-guiding type turnout 100.

In some embodiments of the present invention, as shown in fig. 1 and 10, the two side surfaces of the middle beam 13 are a first surface 131 facing the first side beam 11 and a second surface 132 facing the second side beam 12, respectively, in the first passing state, two ends of the first movable beam 21 in the extending direction (i.e., the train traveling direction) are in direct surface contact with the second surface 132 and the second side beam 12, respectively, so that the first movable beam 21 is clamped between the second side beam 12 and the middle beam 13, and a side surface of the first movable beam 21 facing the first side beam 11 is engaged with the first surface 131. Here, it should be noted that the phrase "the first movable beam 21 is clamped" means that the first movable beam 21 can receive the stopping force in the direction toward at least the intermediate beam 13, which is applied by the second side beam 12, and can receive the stopping force in the direction toward at least the second side beam 12, which is applied by the intermediate beam 13. Here, it should be noted that "engagement" as used herein refers to smooth engagement, i.e., engagement results in a continuous surface of both the guide and support surfaces.

For example, in the example shown in fig. 1 and 10, the first movable beam 21 has a first a end 211 and a first B end 212 at both ends in the extending direction, the first a end 211 and the second surface 132 form direct surface contact (i.e., non-point contact and non-line contact), and the first B end 212 and the second side beam 12 form direct surface contact (i.e., non-point contact and non-line contact). Therefore, after the first movable beam 21 is lifted, the first movable beam 21 can be reliably clamped through the direct surface contact of the two ends of the first movable beam with the fixed beam 1, so that the problem that the first movable beam 21 is unstable in support, such as shaking and shifting, can be effectively avoided, the first movable beam 21 can reliably and effectively support the support wheels of the train, and the support wheels can be ensured to stably and reliably advance on the first movable beam 21. In addition, because the direct surface contact is formed, the production cost can be reduced, and the processing procedure can be simplified.

Preferably, as shown in fig. 2, the second side beam 12, the first movable beam 21 and the middle beam 13 are joined to form a first combined beam X1, and the first combined beam X1 and the first side beam 11 are used as two side support beams of the first guide passage R1, that is, the guide wheels of the train can pass between the first combined beam X1 and the first side beam 11, and the two support wheels of the train can respectively support the first combined beam X1 and the first side beam 11 to run. As shown in fig. 2, the beam width of the first combined beam X1 at any cross section is equal to or greater than the average beam width of the first side beam 11. Therefore, the problem that the supporting wheels of the train cannot be reliably supported due to the narrow beam width does not occur at the joint of the second side beam 12 and the first movable beam 21 and the joint of the first movable beam 21 and the middle beam 13, so that the problems of bumping, jamming and the like of the joint of the supporting wheels running to the first combined beam X1 can be effectively avoided, and the passing reliability of the train can be improved.

As shown in fig. 1 and 10, the shape of the first a-end 211 may match the shape of the corresponding position of the second surface 132 (i.e., the position where the second surface 132 is laterally opposite to the first a-end 211), so that the first movable beam 21 may be in direct surface contact with the second surface 132 using the entire outer surface of the first a-end 211, and the shape of the first B-end 212 may match the shape of the corresponding position of the second side beam 12 (i.e., the position where the second side beam 12 is laterally opposite to the first B-end 212), so that the first movable beam 21 may be in direct surface contact with the second side beam 12 using the entire outer surface of the first B-end 212. Thereby, the reliability of clamping the first movable beam 21 can be greatly improved, and the processing of the first a end 211 and the first B end 212 can be facilitated. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the first movable beam 21 may also be in direct surface contact with the fixed beam 1 by using partial surfaces of both ends. Further, it should be noted that the "lateral direction" described herein refers to a direction perpendicular to the train traveling direction.

As shown in fig. 1 and 10, since the first movable beam 21 is clamped between the fixed beams 1 after being lifted, a reliable limit function is obtained, so that the parts of the first movable beam 21 except for the first a end 211 and the first B end 212 can be processed into the beams with the uniform cross section. Therefore, on the premise of ensuring the supporting reliability of the first movable beam 21, the weight and the production cost of the first movable beam 21 can be greatly reduced, so that the power for driving the first movable beam 21 to ascend and descend can be reduced, and the energy consumption is reduced.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, both ends of the first movable beam 21 in the extending direction may not be in direct surface contact with the second surface 132 and the second side beam 12, for example, the two ends may be in indirect surface contact with an intermediate medium (such as a wear-resistant structural member, a lubricating structural member, a cooling structural member, etc.), for example, the two ends of the first movable beam 21, or the second surface 132 and the second side beam 12 may be provided with the intermediate medium to achieve indirect surface contact.

In some embodiments of the present invention, as shown in fig. 1 and 10, the two side surfaces of the middle beam 13 are a first surface 131 facing the first side beam 11 and a second surface 132 facing the second side beam 12, respectively, in the second traveling state, two ends of the second movable beam 22 in the extending direction (i.e., the train traveling direction) are in direct surface contact with the first surface 131 and the first side beam 11, respectively, so that the second movable beam 22 is clamped between the first side beam 11 and the middle beam 13, and a side surface of the second movable beam 22 facing the second side beam 12 is engaged with the second surface 132. Here, the phrase "the second movable beam 22 is clamped" means that the second movable beam 22 can receive the stopping force in the direction toward at least the intermediate beam 13, which is applied by the first side beam 11, and can receive the stopping force in the direction toward at least the first side beam 11, which is applied by the intermediate beam 13.

For example, in the example shown in fig. 1 and 10, the two ends of the second movable beam 22 in the extending direction are the second a end 221 and the second B end 222, respectively, the second a end 221 and the first surface 131 form direct surface contact (i.e., non-point contact and non-line contact), and the second B end 222 and the first side beam 11 form direct surface contact (i.e., non-point contact and non-line contact). Therefore, after the second movable beam 22 is lifted, the two ends of the second movable beam are in direct surface contact with the fixed beam 1, so that the second movable beam can be reliably clamped, the problem that the second movable beam 22 is unstable in support, such as shaking and shifting, can be effectively solved, the second movable beam 22 can reliably and effectively support the support wheels of the train, and the support wheels can be ensured to stably and reliably move on the second movable beam 22. In addition, because the direct surface contact is formed, the production cost can be reduced, and the processing procedure can be simplified.

Preferably, as shown in fig. 6, the first side beam 11, the second movable beam 22 and the middle beam 13 are joined to form a second combined beam X2, and the second combined beam X2 and the second side beam 12 are used as two side support beams of the second guide passage R2, that is, the guide wheels of the train can pass between the second combined beam X2 and the second side beam 12, and the two support wheels of the train can be supported on the second combined beam X2 and the second side beam 12 respectively. As shown in fig. 6, the beam width of the second combined beam X2 at any cross section is equal to or greater than the average beam width of the second side beam 12. Therefore, the problem that the supporting wheels of the train cannot be reliably supported due to the narrow beam width does not occur at the joint of the first side beam 11 and the second movable beam 22 and the joint of the second movable beam 22 and the middle beam 13, so that the problems of bumping, blocking and the like of the joint of the supporting wheels running to the second combined beam X2 can be effectively avoided, and the passing reliability of the train can be improved.

As shown in fig. 1 and 10, the shape of the second a-end 221 may be matched to the shape of the corresponding position of the first surface 131 (i.e., the position where the first surface 131 and the second a-end 221 are laterally opposite), so that the second movable beam 22 may be in direct surface contact with the first surface 131 using the entire outer surface of the second a-end 221, and the shape of the second B-end 222 is matched to the shape of the corresponding position of the first side beam 11 (i.e., the position where the first side beam 11 and the second B-end 222 are laterally opposite), so that the second movable beam 22 may be in direct surface contact with the first side beam 11 using the entire outer surface of the second B-end 222. Thereby, the reliability of clamping the second movable beam 22 can be greatly improved, and the processing of the second a end 221 and the second B end 222 can be facilitated. Of course, the present invention is not limited to this, and in other embodiments of the present invention, the second movable beam 22 may also be in direct surface contact with the fixed beam 1 by using partial surfaces at both ends. Further, it should be noted that the "lateral direction" described herein refers to a direction perpendicular to the train traveling direction.

As shown in fig. 1 and 10, since the second movable beam 22 can be clamped between the fixed beams 1 after being lifted, a reliable limit effect is obtained, so that the parts of the second movable beam 22 except for the second a end 221 and the second B end 222 can be processed into beams with equal sections. Therefore, on the premise of ensuring the supporting reliability of the second movable beam 22, the weight and the production cost of the second movable beam 22 can be greatly reduced, so that the power for driving the second movable beam 22 to ascend and descend can be reduced, and the energy consumption is reduced.

Of course, the present invention is not limited thereto, and in other embodiments of the present invention, both ends of the second movable beam 22 in the extending direction may not be in direct surface contact with the first surface 131 and the first side beam 11, for example, the second movable beam may be in indirect surface contact with an intermediate medium (such as a wear-resistant structural member, a lubricating structural member, a cooling structural member, etc.), for example, both ends of the first movable beam 21, or the first surface 131 and the first side beam 11 may be provided with the intermediate medium to achieve indirect surface contact.

Next, referring to fig. 19 to 21, a driving apparatus 3 according to an embodiment of the present invention is described.

In some embodiments of the present invention, as shown in fig. 1 to 20, the driving device 3 may be configured to drive one of the first movable beam 21 and the second movable beam 22 to ascend and simultaneously drive the other of the first movable beam 21 and the second movable beam 22 to descend, that is, the ascending and descending are synchronized (i.e., ascending and descending are synchronized and reversed). Therefore, the switching time of the guide channel can be effectively shortened, and the method is suitable for practical application. Of course, the present invention is not limited thereto, and the driving device 3 may be configured to drive one of the ascenders before driving the other one of the descenders, or to drive one of the descenders before driving the other one of the ascenders.

In some specific examples of the present invention, as shown in fig. 19 to 20, the driving device 3 may include: a first scissor lift 31, a second scissor lift 32, and a drive cylinder 33 (which may be an electric cylinder, a pneumatic cylinder, a hydraulic cylinder, etc.). The first scissors lifting platform 31 is used for supporting the first movable beam 21 to lift, and the second scissors lifting platform 32 is used for supporting the second movable beam 22 to lift.

As shown in fig. 19 to 20, the second sliding hinge base 322 is connected to the first sliding hinge base 312 through a connecting rod 34, and the push rod 332 of the driving cylinder 33 is connected to one of the first sliding hinge base 312 and the second sliding hinge base 322, so that by driving one of the first sliding hinge base 312 and the second sliding hinge base 322 to move, the sliding hinge base not driven by the push rod 332 also follows the synchronous movement through the linkage action of the connecting rod 34. In this way, when the push rod 332 extends and contracts, the synchronous and reciprocal movement of the lifting of the first scissors lifting platform 31 and the lifting of the second scissors lifting platform 32 can be realized, that is, the second scissors lifting platform 32 can be lowered while the first scissors lifting platform 31 is lifted, and the first scissors lifting platform 31 can be lowered while the second scissors lifting platform 32 is lifted. Therefore, the driving device 3 has simple and ingenious structure, reliable action and good economical efficiency, and can control the lifting synchronous reciprocal motion of the first movable beam 21 and the second movable beam 22 by only one driving cylinder 33, thereby greatly reducing the input cost.

As shown in fig. 19 to 21, the driving device 3 may further include: the linear rail 35, the linear rail 35 is set up between first fixed hinged base 311 and second fixed hinged base 321, and extend along the direction from first fixed hinged base 311 to second fixed hinged base 321, first slip hinged base 312 and second slip hinged base 322 all cooperate with linear rail 35 and slide along linear rail 35 under the effect of connecting rod 34 in step. Accordingly, the first sliding hinge base 312 and the second sliding hinge base 322 can slide more effectively, reliably, and stably after being pushed by the driving cylinder 33, and the operational reliability of the driving device 3 can be improved. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, since the first sliding hinge base 312 and the second sliding hinge base 322 are connected by the link 34, the linear rail 35 may be omitted.
