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.
An internally guided level crossing switch 100 according to an embodiment of the present invention will be described with reference to the accompanying drawings.
Specifically, the internally guided level crossing switch 100 according to the embodiment of the present invention may be used in a rail transit system, so that the rail transit system provided with the internally guided level crossing switch 100 may have the same advantages as the internally guided level crossing switch 100. The concept and other configurations of the rail transit system are well known to those skilled in the art, such as a subway system, a light rail system, etc., and are not described herein.
As shown in fig. 1, the internally guided level crossing switch 100 may include: a first channel 13 and a second channel 23 arranged in an intersection, one lateral side of the first channel 13 (e.g., the a1 side rail 11 shown in fig. 1) having an a1 notch 110 at a front side of the intersection, another lateral side of the first channel 13 (e.g., the B1 side rail 12 shown in fig. 1) having a B1 notch 120 at a rear side of the intersection, one lateral side of the second channel 23 (e.g., the a2 side rail 21 shown in fig. 1) having an a2 notch 210 at a front side of the intersection, and another lateral side of the second channel 23 (e.g., the B2 side rail 22 shown in fig. 1) having a B2 notch 220 at a rear side of the intersection.
Here, it should be noted that "the first channel 13 and the second channel 23 are arranged to intersect" means: the central extension of the first channel 13 intersects the central extension of the second channel 23. In addition, "front side of intersection" and "rear side of intersection" are merely relative concepts, and do not indicate that a specific orientation is necessary, for example, when the left side of the reference line X-X shown in fig. 1 is "front side of intersection", the right side of the reference line X-X is "rear side of intersection", or when the right side of the reference line X-X shown in fig. 1 is "front side of intersection", the left side of the reference line X-X is "rear side of intersection". For simplicity of description, the following description will be given by taking only the left side of the reference line X-X as the "front side of intersection" and the right side of the reference line X-X as the "rear side of intersection" as an example.
Referring to fig. 2 and 3, the internally guided railroad switch 100 further includes: a first movable beam 3 and a second movable beam 4, wherein the first movable beam 3 is located at the front side of the intersection so that the first movable beam 3 can enter and exit the a1 notch 110 and enter and exit the a2 notch 210, and the second movable beam 4 is located at the rear side of the intersection so that the second movable beam 4 can enter and exit the B1 notch 120 and enter and exit the B2 notch 220. Specifically, the first movable beam 3 is movable between an a1 position 301 (shown in fig. 2) moving into the second channel 23 to fill the a1 notch 110, and an a2 position 302 (shown in fig. 3) moving into the first channel 13 to fill the a2 notch 210, and the second movable beam 4 is movable between a B1 position 401 (shown in fig. 2) moving into the second channel 23 to fill the B1 notch 120, and a B2 position 402 (shown in fig. 3) moving into the first channel 13 to fill the B2 notch 220.
As shown in fig. 2, when the first movable beam 3 moves to the a1 position 301, the second movable beam 4 moves to the B1 position 401, the first movable beam 3 can fill the a1 gap 110 on one side of the width of the first passageway 13, and the second movable beam 4 can fill the B1 gap 120 on the other side of the width of the first passageway 13, at this time, the gaps on both sides of the width of the first passageway 13 are respectively filled by the first movable beam 3 and the second movable beam 4, so that the first passageway 13 can play a guiding role, so that the internally-guided type crossing switch 100 can assume the first passing state guided by the first passageway 13.
As shown in fig. 3, when the first movable beam 3 moves to the a2 position 302 and the second movable beam 4 moves to the B2 position 402, the first movable beam 3 can fill the a2 gap 210 on one side of the width of the second channel 23, and the second movable beam 4 can fill the B2 gap 220 on the other side of the width of the second channel 23, at this time, the gaps on both sides of the width of the second channel 23 are respectively filled by the first movable beam 3 and the second movable beam 4, so that the second channel 23 can play a guiding role, so that the internally-guided railroad switch 100 can assume the second passage state guided by the second channel 23.
Therefore, the internal guide type level crossing turnout 100 according to the embodiment of the invention has a very smart structure, and the switching between the first passing state and the second passing state can be realized only by adjusting the positions of the first movable beam 3 and the second movable beam 4, so that the internal guide type level crossing turnout 100 has the advantages of small volume, light switching, low cost, economy and reasonableness. Moreover, because the interior direction formula level crossing switch 100 is when showing first traffic state, first movable beam 3 and second movable beam 4 are all accomodate in second passageway 23, and when showing second traffic state, first movable beam 3 and second movable beam 4 are all accomodate in first passageway 13, thereby can make interior direction formula level crossing switch 100 not need the extra space except first passageway 13 and second passageway 23, in order to further reduce the whole volume of interior direction formula level crossing switch 100, moreover, because first movable beam 3 and second movable beam 4 are accomodate in the non-traffic lane, still can not influence the normal work of traffic lane, thereby can further improve the operational reliability of interior direction formula level crossing switch 100.
In some embodiments of the present invention, as shown in fig. 4 and 5, the internally guided level crossing switch 100 may include: the first fixing beam 1 and the second fixing beam 2 are arranged in a crossing mode, wherein the first fixing beam 1 comprises an A1 side beam 11 and a B1 side beam 12 which are arranged in parallel to define a first channel 13, the second fixing beam 2 comprises an A2 side beam 21 and a B2 side beam 22 which are arranged in parallel to define a second channel 23, the part of the A1 side beam 11 penetrating into the second channel 23 is cut to form an A1 notch 110, the part of the B1 side beam 12 penetrating into the second channel 23 is cut to form a B1 notch 120, the part of the A2 side beam 21 penetrating into the first channel 13 is cut to form an A2 notch 210, and the part of the B2 side beam 22 penetrating into the first channel 13 is cut to form a B2 notch 220. Therefore, the internal guide type turnout is simple and light in structure and low in cost, and the first channel 13 and the second channel 23 meeting the requirements can be effectively constructed. Of course, the present invention is not limited thereto, and for example, in other embodiments of the present invention as shown in fig. 6, the first channel 13 and the second channel 23 may be formed in one integral structure.
For example, in the specific example shown in fig. 2, the first movable beam 3 is a V-block and may include: an a1 sub-beam 31 extending in the same direction as the a1 side beam 11 and an a2 sub-beam 32 extending in the same direction as the a2 side beam 21. For example, in the specific example shown in fig. 2, the second movable beam 4 is a V-block and may include: a B1 sub-beam 41 extending in the same direction as the B1 side beam 12 and a B2 sub-beam 42 extending in the same direction as the B2 side beam 22.
As shown in fig. 2 and 4, when the inner-guide type level crossing switch 100 is in the first passing state, the first movable beam 3 moves to the a1 position 301, at this time, the a2 sub-beam 32 moves into the second passage 23, and the a1 sub-beam 31 fills the a1 notch 110 to connect two sections of the a1 side beam 11 located at two sides of the a1 notch 110, namely, the a1 side beam crossing front side section 111 and the a1 side beam crossing rear side section 112, that is, the a1 side beam crossing front side section 111, the a1 sub-beam 31 and the a1 side beam crossing rear side section 112, so as to connect the seamlessly-spliced a1 guide side surface 1311 and a1 support top surface 1312. And the second movable beam 4 moves to the B1 position 401, at this time, the B2 sub-beam 42 moves into the second channel 23, the B1 sub-beam 41 fills the B1 gap 120 to connect two sections of the B1 side beam 12 located at two sides of the B1 gap 120, namely, the B1 side beam crossing front side section 121 and the B1 side beam crossing rear side section 122, namely, the B1 side beam crossing front side section 121, the B1 sub-beam 41 and the B1 side beam crossing rear side section 122, so that the seamlessly spliced B1 guide side surfaces 1321 and B1 support the top surface 1322. Thus, the guide wheels of the train may run between guide side A1 1311 and guide side B1 1321 along guide side A1 1311 and guide side B1 1321, and the two support wheels of the train may run supported on support top A1 1312 and support top B1 1322, respectively.
As shown in fig. 3 and 5, when the inner-guided crossing switch 100 is in the second passing state, the first movable beam 3 moves to the a2 position 302, at this time, the a1 sub-beam 31 moves into the first passage 13, and the a2 sub-beam 32 fills the a2 notch 210 to connect two sections of the a2 side beam 21 located at two sides of the a2 notch 210, namely, the a2 side beam crossing front side section 211 and the a2 side beam crossing rear side section 212, that is, the a2 side beam crossing front side section 211, the a2 sub-beam 32 and the a2 side beam crossing rear side section 212, so as to connect the seamlessly spliced a2 guide side faces 2311 and a2 support top faces 2312. And the second movable beam 4 moves to the B2 position 402, at this time, the B1 sub-beam 41 moves into the first channel 13, the B2 sub-beam 42 fills the B2 notch 220 to connect two sections of the B2 side beam 22 located at two sides of the B2 notch 220, namely, the B2 side beam cross front side section 221 and the B2 side beam cross rear side section 222, namely, the B2 side beam cross front side section 221, the B2 sub-beam 42 and the B2 side beam cross rear side section 222, so that the seamlessly spliced B2 guide side surfaces 2321 and the B2 support the top surface 2322. Thus, the guide wheels of the train can run between the guide side a2 2311 and the guide side B2 2321 along the guide side a2 2311 and the guide side B2 2321, and the two support wheels of the train can run supported on the support top a2 2312 and the support top B2 2322, respectively.
Therefore, the first movable beam 3 and the second movable beam 4 are simple in structure, light and low in cost, and the first movable beam 3 and the second movable beam 4 can be driven to move by adopting small power, so that the driving energy consumption can be effectively reduced.
Of course, the present invention is not limited to this, for example, in other embodiments of the present invention shown in fig. 6, the first movable beam 3 and the second movable beam 4 may also be respectively a single integral structural block, such as a triangular block, instead of being composed of two sub-beams.
Therefore, the specific structure of the first movable beam 3 according to the embodiment of the present invention is not limited, and the advantageous effects described above can be achieved by satisfying only one of the following requirements. Such as: the first movable beam 3 includes: a first surface 310 and a second surface 320, for example, the first surface 310 is formed on a side surface of the a1 sub beam 31 facing the B1 side beam 12, the second surface 320 is formed on a side surface of the a2 sub beam 32 facing the B2 side beam 22, the first surface 310 extends in the same direction as the a1 side beam 11, and the second surface 320 extends in the same direction as the a2 side beam 21.
As shown in fig. 2, at position 301 a1, the first runner 3 moves into the second channel 23, and the first surface 310 engages the side walls of the a1 edge beam 11 on both sides of the a1 notch 110 (e.g., side wall 111 of the a1 edge beam cross front section 111 facing the B1 edge beam 12 and side wall 112F of the a1 edge beam cross rear section 112 facing the B1 edge beam 12 as shown in fig. 2).
As shown in fig. 3, at position 302 a2, the first runner 3 moves into the first channel 13 and the second surface 320 engages the side walls of the a2 edge beam 21 on either side of the a2 notch 210 (a 2 edge beam cross front section 211 facing side wall 211F of B2 edge beam 22 and a2 edge beam cross back section 212 facing side wall 212F of B2 edge beam 22 as shown in fig. 3).
This can improve the reliability of the guiding action. Alternatively, in the A1 position 301, the second surface 320 is in surface contact abutment with the B2 rocker 22, and in the A2 position 302, the first surface 310 is in surface contact abutment with the B1 rocker 12. Thereby, the positioning reliability of the first movable beam 3 can be improved.
It is thus described that the specific structure of the second movable beam 4 according to the embodiment of the present invention is not limited, and the advantageous effects described above can be achieved by satisfying only one of the following requirements. Such as: the second movable beam 4 includes: a third surface 410 and a fourth surface 420, for example, the third surface 410 may be formed on a side surface of the B1 sub beam 41 facing the a1 side beam 11, for example, the fourth surface 420 may be formed on a side surface of the B2 sub beam 42 facing the a2 side beam 21, the third surface 410 extends in the same direction as the B1 side beam 12, and the fourth surface 420 extends in the same direction as the B2 side beam 22.
As shown in fig. 2, in position 401 of B1, the second runner 4 moves into the second channel 23, and the third surface 410 engages the side wall of the B1 edge beam 12 on both sides of the B1 notch 120 (e.g., side wall 121F of B1 edge beam cross front section 121 facing the a1 edge beam 11 and side wall 122F of B1 edge beam cross rear section 122 facing the a1 edge beam 11 as shown in fig. 2).
As shown in fig. 3, in position 402 at B2, the second movable beam 4 moves into the first channel 13, and the fourth surface 420 engages the side wall of the B2 edge beam 22 on both sides of the B2 notch 220 (as shown in fig. 3, the B2 edge beam cross front section 221 faces the side wall 221F of the a2 edge beam 21 and the B2 edge beam cross rear section 222 faces the side wall 222F of the a2 edge beam 21).
This can improve the reliability of the guiding action. Alternatively, the fourth surface 420 may be in face contacting abutment with the A2 sill 21 in the B1 position 401 and the third surface 410 may be in face contacting abutment with the A1 sill 11 in the B2 position 402. Thereby, the positioning reliability of the first movable beam 3 can be improved.
As shown in fig. 1 and 2, since the a2 sub-beam 32 extends in the same direction as the a2 side beam 21 and the a2 side beam 21 is parallel to the B2 side beam 22, so that the a2 sub-beam 32 can be parallel to the B2 side beam 22, when the first movable beam 3 moves to the a1 position 301, the a2 sub-beam 32 can be in surface contact with the B2 side beam 22, so that the B2 side beam 22 can reliably support the first movable beam 3 through the a2 sub-beam 32 to ensure that the a1 sub-beam 31 can be stably and reliably located in the a1 notch 110, so that the structures of the a1 guide side surface 1311 and the a1 for supporting the top surface 1312 are reliable, and the stability and reliability of the turnout 100 in the first passing state are improved.
As shown in fig. 1 and 2, since the B2 sub-beam 42 extends in the same direction as the B2 side beam 22 and the B2 side beam 22 is parallel to the a2 side beam 21, so that the B2 sub-beam 42 can be parallel to the a2 side beam 21, when the second movable beam 4 moves to the B1 position 401, the B2 sub-beam 42 can be in surface contact abutment with the a2 side beam 21, so that the a2 side beam 21 can reliably support the second movable beam 4 through the B2 sub-beam 42 to ensure that the B1 sub-beam 41 can be stably and reliably positioned in the B1 notch 120, so that the structures of the guide side surfaces 1321 of the B1 and the top surface supported by the B461322 2 sub-beam 42 are reliable, and the stability and reliability of the turnout 100 in the first passing state are improved.
As shown in fig. 1 and 3, since the a1 sub-beam 31 extends in the same direction as the a1 side beam 11 and the a1 side beam 11 is parallel to the B1 side beam 12, so that the a1 sub-beam 31 can be parallel to the B1 side beam 12, when the first movable beam 3 moves to the a2 position 302, the a1 sub-beam 31 can be in surface contact with the B1 side beam 12, so that the B1 side beam 12 can reliably support the first movable beam 3 through the a1 sub-beam 31 to ensure that the a2 sub-beam 32 can be stably and reliably located in the a2 notch 210, so that the structures of the a2 guide side surfaces 2311 and the a2 for supporting the top surface 2312 are reliable, and the stability and reliability of the inner guide type intersection 100 in the second passing state are improved.
As shown in fig. 1 and 3, since the B1 sub-beam 41 extends in the same direction as the B1 side beam 12 and the B1 side beam 12 is parallel to the a1 side beam 11, so that the B1 sub-beam 41 can be parallel to the a1 side beam 11, when the second movable beam 4 moves to the B2 position 402, the B1 sub-beam 41 can be in surface contact with the a1 side beam 11, so that the a1 side beam 11 can reliably support the second movable beam 4 through the B1 sub-beam 41 to ensure that the B2 sub-beam 42 can be stably and reliably located in the B2 notch 220, so that the structures of the B2 guide side surfaces 2321 and B2 for supporting the top surface 2322 are reliable, and the stability and reliability of the inner guide type intersection 100 in the second passing state are improved.

The driving device 5 provided below is simple in structure, only needs one driving motor 51, is matched with simple gear transmission to realize changing the movement direction, utilizes simple transmission shafts and couplers to carry out movement transmission, and utilizes gear and rack transmission to realize changing rotation into translational motion, so that the synchronous reverse translation of the first movable beam 3 and the second movable beam 4 can be simply and effectively ensured.
As shown in fig. 7-10, the driving device 5 uses a driving motor 51 to drive the first movable beam 3 and the second movable beam 4 to synchronously and reversely translate, and specifically, the driving device 5 may include: the driving mechanism comprises a driving motor 51, a driving gear 521, a driven gear 522, a first transmission shaft 531, a first rack 532, a first gear 533, a first gear shaft 534, a first coupler 535, a first bracket 536, a first bearing 537, a second transmission shaft 541, a second rack 542, a second gear 543, a second gear shaft 544, a second coupler 545, a second bracket 546 and a second bearing 547.

Moreover, because one driving motor 51 is adopted to simultaneously drive the first movable beam 3 and the second movable beam 4 to synchronously and reversely translate, the problem that when two motors are adopted to respectively drive the two movable beams to move, the movement is asynchronous and the switching time is increased can be avoided.

In short, by adopting the meshing of the driving gear 521 and the driven gear 522 with the transmission ratio of 1:1, the same movement rates of the first movable beam 3 and the second movable beam 4 can be ensured, synchronous operation and in-place switching can be realized, and the efficiency during switching can be improved.
Fourthly, the power output by the driving motor 51 is transmitted to the first movable beam 3 and the second movable beam 4 through the first transmission shaft 531 and the second transmission shaft 541, so that long-distance transmission can be realized, thereby ensuring that one driving motor 51 can drive two movable beams.
Fifthly, the first bracket 536 is arranged at the bottom of the first gear shaft 534, and the first bracket 536 can play a role in supporting the first gear shaft 534, so that the problem of bending and downwarping caused by the overlong length of the first transmission shaft 531 is prevented, normal meshing between the first gear 533 and the first rack 532 is ensured, the meshing slipping phenomenon caused by the separation of the first rack 532 and the first gear 533 is avoided, the reliability of driving the first movable beam 3 is improved, and the first movable beam 3 can be smoothly translated. Meanwhile, the first support 536 can be provided with a split bearing bush-shaped first bearing 537, so that friction between the first support 536 and the first gear shaft 534 is reduced, a wear beam is reduced, stability and reliability of action are improved, and the split bearing bush-shaped first bearing 537 is convenient for installation of the first gear shaft 534 and is convenient for later maintenance, namely only the worn bearing bush needs to be replaced during maintenance.
