Description

Technical Field

[0001] The present invention relates to the technical field of double-track railways, and specifically to a shared-rail conversion type double-track railway turntable system. Background Art

[0002] A double-track railway is a railway layout method that can allow locomotives and rolling stocks with two different gauges to run on one line. In the early days, locomotive turning was for the locomotive driver with a cab at one end to drive forward facing the front and reverse. Although modern electric locomotives and diesel locomotives have cabs at both ends, they need to be reversed regularly to achieve even wear on both sides of the wheels, avoid damage caused by excessive unilateral wear, and extend the service life of the wheel set.

[0003] There are generally two ways to turn a locomotive in a double-track section. The first way is to achieve it through the double-track railway triangle: locomotives of two gauge railways move forward and backward on the double-track railway triangle to achieve locomotive turning.

[0004] The second way is to achieve locomotive turning for two different gauge locomotives through two locomotive turntables, namely a broad-gauge turntable and a narrow-gauge turntable: locomotives of broad-gauge railways or narrow-gauge railways drive onto the corresponding railway turntables respectively, and the turntables carry the locomotives and rotate horizontally by 180 degrees together to achieve locomotive turning.

[0005] However, the first way to turn a railway locomotive is achieved through the double-track railway triangle. The double-track railway triangle is laid with double tracks, which can meet the turning of locomotives of two gauges. However, the double-track railway triangle has a long track laying length, a large floor area, and serious land waste. The locomotive travels a long distance through forward and backward movement, and the efficiency is not high. In the case of increasingly precious urban land, the double-track railway triangle is being demolished and replaced by railway locomotive turntables. The second way is to achieve railway locomotive turning through locomotive turntables. However, ordinary railway locomotive turntables are only applicable to railways of one gauge. Since a double-track railway consists of three steel rails, one of which is a shared rail, locomotives of two gauge railways run on the double-track railway. Because the rotation center of the turntable cannot coincide with the centers of two gauges at the same time. Locomotives of two gauges cannot turn on the same ordinary locomotive turntable, and two turntables need to be set up, one for broad-gauge locomotive turning and the other for narrow-gauge locomotive turning. Using two turntables requires two sets of equipment and railway connection lines, occupying a large floor area and having a large project investment.

[0006] There are only two steel rails on the existing ordinary railway locomotive turntable. The rotation center of the turntable is set on the axis of symmetry of the two steel rails, overlapping with the axis of symmetry of the railway locomotive. After the railway locomotive rotates 180 degrees on the turntable, the left rail on the turntable rotates to the position of the right rail, and at the same time, the right rail rotates to the position of the left rail. The left and right rails on the turntable are symmetrically swapped, which does not affect the alignment with the connecting rails outside the turntable. After the railway locomotive on the turntable rotates 180 degrees, the position of the axis of symmetry remains unchanged, and it can smoothly drive out of the turntable to achieve the function of turning the railway locomotive. There are only two steel rails on the existing ordinary railway locomotive turntable, which can only meet the turning of railway locomotives with one gauge. The double-track railway consists of three steel rails, and railway locomotives with two different gauges run on the double-track railway. One of the steel rails is a common rail, for example: the 1435mm standard gauge and the 1000mm meter gauge, the 1520mm gauge in Russia and the 1435mm standard gauge. Since the rotation center of the turntable cannot coincide with the centers of the two gauges at the same time. After the third rail of the double-track turntable rotates 180 degrees, the position of the third rail changes and cannot coincide with the third rail outside the turntable. Summary of the Invention

[0007] The purpose of the present invention is to provide a common-rail conversion type railway double-track turntable system, which can at least solve some defects in the prior art.

[0008] To achieve the above purpose, the embodiments of the present invention provide the following technical solutions: A common-rail conversion type railway double-track turntable system includes a turntable, and also includes four tracks extending from inside the turntable to outside the turntable. The four tracks are arranged at intervals in the same direction. The two outer tracks are both wide tracks, and the two inner tracks are both narrow tracks. The two outer tracks and the two inner tracks are connected. There is an annular track in the turntable for the railway locomotive to rotate 180 degrees, and there is a common-rail switch outside the turntable.

[0009] Further, the four tracks outside the turntable are respectively the outer wide track A, the outer wide track B, the outer narrow track C, and the outer narrow track D, and the outer wide track B, the outer narrow track C, the outer narrow track D, and the outer wide track A are arranged in sequence; the four tracks inside the turntable are respectively the inner wide track A, the inner wide track B, the inner narrow track C, and the inner narrow track D, and the inner wide track B, the inner narrow track C, the inner narrow track D, and the inner wide track A are arranged in sequence.

[0010] Further, when a railway locomotive with a wide gauge turns around, the wheels of the railway locomotive with a wide gauge respectively fall on the inner wide track A and the inner wide track B.

[0011] Further, when the narrow-gauge railway locomotive turns around, the wheels of the narrow-gauge railway locomotive respectively fall on the inner-wide rail A and the inner-narrow rail C of the disc.

[0012] Further, the outer-narrow rail C of the disc is connected with an extension section extending away from the turntable.

[0013] Further, the common-rail conversion turnout includes a movable switch rail A that can closely adhere to or leave the outer-narrow rail C and the wide rail B, and a movable switch rail B that can closely adhere to or leave the outer-wide rail A and the narrow rail D, and a turnout switch machine for switching the switch rail A and the switch rail B.

[0014] Further, the common-rail conversion turnout also includes guard rails A and B for the curved stock of the narrow-gauge locomotive to convert the restricted path of the common rail.

[0015] Further, the outer-wide rail A of the disc is a common track for two gauges.

[0016] Further, the railway locomotives with two different gauges enter the inner-sleeve rail line of the turntable through the common-rail conversion turnout, and also enter the outer-sleeve rail line of the turntable from the inner line of the turntable through the common-rail conversion turnout.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. The common-rail conversion type railway sleeve rail turntable system is adopted to replace the traditional sleeve rail railway triangle to realize the turning operation of railway locomotives with two different gauges in the same turntable. Generally, a railway triangle covers an area of about 16,000 m 2 , about 900 m of sleeve rails are laid, and 4 sets of sleeve rail turnouts are laid. While the common-rail conversion type track turntable of this patent only covers an area of about 1,670 m 2 , only 100 m of sleeve rails are laid, and one set of movable turnout. The land occupation is only 10.4% of that of the railway triangle. The investment is only 30% of that of the railway triangle.

[0019] 2. The common-rail conversion type railway sleeve rail turntable is adopted to replace the traditional two railway locomotive turntables, and the land occupation is only 50% of that of the two traditional railway turntables. The investment is only 60% of that of the traditional railway turntable.

[0020] 3. Four tracks are adopted inside the turntable. After the railway locomotive turns around, the sleeve rail turntable does not need to rotate 180 degrees to return to the position, reducing the return time of the turntable.

[0021] 4. The turntable and the turnout switch machine are driven by electricity, which is conducive to automatic control, energy conservation and environmental protection.

[0022] 5. Shared-rail conversion type railway nested-rail turntable, which doubles the time efficiency of railway locomotive turning compared with the railway triangle, and has the same efficiency as the traditional railway turntable. Description of the Drawings

Detailed Embodiment

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 3 、 Figure 4 and Figure 5, an embodiment of the present invention provides a common - track conversion - type railway sleeve - rail turntable system, including a turntable 1 and four tracks extending from inside the turntable 1 to outside the turntable 1. The four tracks are arranged at intervals in the same direction. The two outer tracks are both wide - gauge tracks, and the two inner tracks are both narrow - gauge tracks. The two outer tracks and the two inner tracks are connected. The outer tracks are the common tracks for the inner narrow - gauge lines. There is an annular track 13 inside the turntable 1 for the railway locomotive 10 to rotate 180 degrees, and there is a common - rail conversion turnout 11 outside the turntable 1. In this embodiment, this sleeve - rail railway turntable system mainly includes the annular track 13 under the turntable, the four tracks, and the common - rail conversion turnout 11 outside the turntable. For the refinement of the tracks, for the convenience of detailed description, the four tracks are arranged at intervals in the same direction. The gauge of the two outer tracks is the wide - gauge, and the gauge of the two inner tracks is narrower than that of the outer tracks. The wide - gauge means the gauge size of the wide - gauge line, and the narrow - gauge means the track size of the narrow - gauge line. For a clearer description, the four tracks outside the turntable 1 are respectively defined as the outer wide - gauge A9, the outer wide - gauge B6, the outer narrow - gauge C7, and the outer narrow - gauge D8, and the outer wide - gauge B6, the outer narrow - gauge C7, the outer narrow - gauge D8, and the outer wide - gauge A9 are arranged in sequence; the four tracks inside the turntable 1 are respectively defined as the inner wide - gauge A5, the inner wide - gauge B2, the inner narrow - gauge C3, and the inner narrow - gauge D4, and the inner wide - gauge B2, the inner narrow - gauge C3, the inner narrow - gauge D4, and the inner wide - gauge A5 are arranged in sequence. Through the above - mentioned system, compared with the traditional Figure 1 shown in the triangular - line turning around, which requires three turnouts and three buffers (represented by turnout 1, turnout 2, turnout 3, buffer 1, buffer 2, and buffer 3) respectively, it can save land and investment costs. Similarly, compared with the traditional Figure 2 shown in the turntable 1, it can also greatly save land and investment costs. In the traditional turntable 1, there are only two railway tracks. The railway locomotive 10 enters the outer - rail railway of the turntable 1 through the common - rail conversion turnout 11.

[0031] The following are specific embodiments:

[0032] As an optimized solution of the embodiment of the present invention, please refer to Figure 3 、 Figure 4 and Figure 5, when the broad - gauge railway locomotive 10 turns around, the wheels of the broad - gauge railway locomotive 10 respectively fall on the in - disk broad - gauge A5 and the in - disk broad - gauge B2. Specifically, the railway locomotive 10 enters the turntable 1 from the out - of - disk broad - gauge A9 (shared rail) and the out - of - disk broad - gauge B6 outside the turntable 1. The railway locomotive 10 occupies the in - disk broad - gauge A5 and the in - disk broad - gauge B2. Then, after the railway locomotive 10 rotates 180 degrees with the turntable 1, the in - disk broad - gauge A5 and the in - disk broad - gauge B2 of the turntable 1 symmetrically exchange positions and can be aligned with the out - of - disk broad - gauge B6 and the out - of - disk broad - gauge A9 connected outside the turntable 1. The locomotive drives out of the turntable 1, and the locomotive successfully realizes turning around.

[0033] As an optimized solution of the embodiment of the present invention, please refer to Figure 3 , Figure 4 and Figure 5 , when the narrow - gauge railway locomotive 10 turns around, the wheelsets of the narrow - gauge railway locomotive 10 enter and respectively fall on the in - disk broad - gauge A5 and the in - disk narrow - gauge C3. The shared - rail turnout 11 includes a movable switch rail A14 that can closely adhere to or leave the out - of - disk narrow - gauge C7 and a movable switch rail B15 of the out - of - disk broad - gauge A9. The shared - rail turnout 11 also includes guard rails A16 and guard rails B17 for restricting the curved path of the shared rail conversion of the narrow - gauge locomotive. Specifically, the switch machine 18 works to make the movable switch rail A14 closely adhere to the out - of - disk narrow - gauge C7, and at the same time the movable switch rail B15 leaves the out - of - disk broad - gauge A9. The narrow - gauge railway locomotive 10 enters the turntable 1 from the out - of - disk broad - gauge A9 (shared rail) and the out - of - disk narrow - gauge C7 outside the turntable 1. The railway locomotive 10 occupies the in - disk broad - gauge A5 and the in - disk narrow - gauge C3. After the narrow - gauge railway locomotive 10 rotates 180 degrees with the turntable 1, the in - disk broad - gauge A in the turntable 1 is switched to the position of the in - disk broad - gauge B2, and the in - disk narrow - gauge C3 is switched to the position of the in - disk narrow - gauge D4. Since the in - disk narrow - gauge D4 corresponds to the position of the out - of - disk narrow - gauge D8, after the railway locomotive 10 turns around and drives out of the turntable 1, it occupies the out - of - disk broad - gauge B6 and the out - of - disk narrow - gauge D8, rather than the out - of - disk broad - gauge A9 and the out - of - disk narrow - gauge C7 when the locomotive drives in, as Figure 4 shown. Therefore, a section of rail is extended along the out - of - disk narrow - gauge D8 outside the turntable 1, that is, an extended section is formed, so that the narrow - gauge railway locomotive 10 after turning around drives out along the out - of - disk broad - gauge B6 and the out - of - disk narrow - gauge D8 and enters the shared - rail turnout 11 under the guidance of the guard rails A and the guard rails B, so that the locomotive transitions from the out - of - disk broad - gauge B6 and the out - of - disk narrow - gauge D8 to the out - of - disk narrow - gauge C7 and the out - of - disk broad - gauge A9. The narrow - gauge locomotive after turning around successfully enters the outer - turntable rail railway.

[0034] As an optimized solution of the embodiment of the present invention, please refer to Figure 5, the shared rail turnout 11 includes a movable switch rail A14 that can closely adhere to or depart from the narrow gauge track C7 outside the disc, and a movable switch rail B15 that can closely adhere to or depart from the wide gauge track A9 outside the disc. The shared rail turnout 11 further includes guard rails A16 and B17 for restricting the path of the narrow gauge locomotive in the curved track. In this embodiment, before the narrow gauge railway locomotive 10 enters the narrow gauge turnout, the turnout switch machine 18 operates to make the movable switch rail A14 closely adhere to the narrow gauge track C7 outside the disc, while the movable switch rail B15 departs from the wide gauge track A9 outside the disc. The narrow gauge railway locomotive 10 passes through the movable switch rail A14 from the wide gauge track A9 and the narrow gauge track C7 outside the disc, runs straight and enters the sleeve rail turntable. After the sleeve rail turntable rotates 180 degrees, the narrow gauge locomotive is located at the positions of the wide gauge track B6 and the narrow gauge track D8 outside the right disc. The turnout switch machine 18 operates to make the movable switch rail A14 depart from the narrow gauge track C7 outside the disc, while the movable switch rail B15 closely adheres to the wide gauge track A9 outside the disc. The railway locomotive 10 after turning its head drives out of the turntable 1, passes through the guard rails A16 and B17 with the curved track restricted, passes through the movable switch rail B15, and changes from running on the wide gauge track B6 and the narrow gauge track D8 outside the disc to running on the narrow gauge track C7 and the wide gauge track A9 outside the disc, realizing the rail conversion of the shared rail for narrow and wide gauges. The wide gauge railway locomotive 10 enters the turnout from the wide gauge track A9 and the wide gauge track B6 outside the disc. The turnout switch machine 18 operates to make the movable switch rail A14 closely adhere to the narrow gauge track C7 outside the disc, while the movable switch rail B15 departs from the wide gauge track A9 outside the disc. The railway locomotive 10 passes straight through the turnout and enters the locomotive turntable. After a 180-degree conversion, the wide gauge tracks A5 and B2 inside the disc are swapped in position. The wide gauge railway locomotive 10 drives out straight from the wide gauge track A9 and the wide gauge track B6 outside the disc.

[0035] As an optimized solution of the embodiment of the present invention, please refer to Figure 3 , Figure 4 and Figure 5 , there is a railway buffer stop 12 provided outside the turntable 1.

[0036] As an optimized solution of the embodiment of the present invention, please refer to Figure 3 , Figure 4 and Figure 5 , four tracks are adopted inside the turntable. After the railway locomotive 10 turns its head, the turntable 1 does not need to rotate 180 degrees to return to its original position, saving the time for the turntable 1 to return to its original position.

[0037] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
