Description

Technical Field

[0001] The present invention relates to the technical field of narrow and wide gauge co - linear sleeve - rail railways, and particularly to a conversion sleeve - rail turntable system for narrow - gauge common rails within a disc. Background Art

[0002] A sleeve - rail railway is a railway layout method that can allow locomotives and rolling stocks with two different gauge distances to run on the same line. In the early days, locomotive turning was for the locomotive driver with a cab at one end to drive forward facing the front for commutation. Although modern electric locomotives and diesel locomotives have cabs at both ends, they need to be commutated regularly to achieve balanced 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 for locomotive turning in a sleeve - rail railway section. The first way is achieved through the sleeve - rail railway triangle: locomotives with two different gauge distances move forward and backward on the sleeve - rail 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 wide - gauge turntable and a narrow - gauge turntable: wide - gauge railway locomotives or narrow - gauge railway locomotives 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, for the first way, locomotive turning of railway locomotives is achieved through the sleeve - rail railway triangle. The sleeve - rail is laid on the railway triangle, which can meet the locomotive turning of locomotives with two different gauge distances. However, the laying length of the sleeve - rail on the railway triangle is long, the floor area is large, and land waste is serious. 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 railway triangle is being demolished and replaced by railway locomotive turntables. For the second way, locomotive turning of railway locomotives is achieved through locomotive turntables, but ordinary railway locomotive turntables are only applicable to railways with one gauge distance. Since a sleeve - rail railway consists of three steel rails, locomotives with two different gauge distances run on the sleeve - rail railway. Because the rotation center of the turntable cannot coincide with the centers of both gauge distances at the same time, locomotives with two different gauge distances cannot achieve turning on the same ordinary locomotive turntable. Two turntables need to be set up, one for wide - 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 involving a large engineering investment.

[0006] There are only two steel rails on the existing turntable of ordinary railway locomotives. 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 external connecting rails of 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 turntable of ordinary railway locomotives, 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. 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.

[0007] Content

[0008] The purpose of the present invention is to provide a double-track turntable system with in-disk narrow-gauge common-rail conversion, which can at least solve the defects in the prior art.

[0009] To achieve the above object, the embodiments of the present invention provide the following technical solutions: A double-track turntable system with in-disk narrow-gauge common-rail conversion includes a turntable, and also includes three tracks extending from the in-disk access end of the turntable to the outside of the turntable. The three tracks are arranged at intervals in the same direction. The two outer tracks are of wide-gauge, and the inner track is of narrow-gauge. There is an annular track in the turntable for the railway locomotive to rotate 180 degrees, and there is a set of two narrow-gauge common-rail turnout switches between the two ends of the in-disk line.

[0010] Further, the three tracks at the in-disk access end are respectively the out-of-disk wide-gauge A, the out-of-disk wide-gauge B, and the out-of-disk narrow-gauge C, and the out-of-disk wide-gauge B, the out-of-disk narrow-gauge C, and the out-of-disk wide-gauge A are arranged in sequence; the four tracks in the turntable are respectively the in-disk wide-gauge A, the in-disk wide-gauge B, the in-disk narrow-gauge C, and the in-disk narrow-gauge D, and the in-disk wide-gauge B, the in-disk narrow-gauge C, the in-disk narrow-gauge D, and the in-disk wide-gauge A are arranged in sequence.

[0011] Further, the out-of-disk wide-gauge A at the access end is a common rail, and the out-of-disk wide-gauge B at the end is a common rail.

[0012] Further, when a railway locomotive with a wide gauge turns around, the wheel sets of the railway locomotive with a wide gauge respectively fall on the in-disk wide-gauge A and the in-disk wide-gauge B.

[0013] 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 at the access end, and fall on the inner-wide rail B and the inner-narrow rail D of the disc at the end end.

[0014] Further, each of the narrow-gauge common-rail turnout switches includes a pair of guard rails and a set of turnout switches for realizing the gauge change of the narrow-gauge common rail.

[0015] Further, each of the narrow-gauge common-rail turnout switches also includes the connection of the inner-wide rail and the inner-narrow rail of the disc. The inner-wide rail A of one of the narrow-gauge common-rail turnout switches is connected to the inner-narrow rail D of the narrow-gauge turnout switch, and the inner-wide rail B of the other narrow-gauge common-rail turnout switch is connected to the inner-narrow rail C of the disc. The common rail at the access end of the disc is rail A, and the common rail at the end end is rail B.

[0016] Further, the railway locomotive enters the outer-rail railway of the turntable through the narrow-gauge turnout switch.

[0017] Further, a railway bumper is provided at one end outside the turntable.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] 1. The common-rail conversion type railway sleeve-rail turntable system is adopted to replace the traditional railway sleeve-rail triangle to realize the turning operation of railway locomotives with two gauges, wide gauge and narrow gauge. 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 translational rail turntable of this patent only covers an area of about 1,600 m 2 , only 100 m of sleeve rails are laid, and one set of turnout switch is provided. The land occupation is only 10.4% of that of the railway triangle. The investment is only 30% of that of the railway triangle.

[0020] 2. The common-rail conversion type railway sleeve-rail turntable is adopted to replace the traditional two railway locomotive turntables. 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.

[0021] 3. The turntable is driven by electricity, which is conducive to automatic control, energy conservation and environmental protection.

[0022] 4. For the common-rail conversion type railway sleeve-rail turntable, compared with the railway triangle, the time efficiency of the railway locomotive turning is doubled, and it is equivalent to the efficiency of the traditional railway turntable. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying 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 of 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, the present invention provides a turntable system with a narrow-gauge common rail conversion type nested rail turntable 1, which includes a turntable 1 and three tracks extending from inside the turntable 1 to outside the turntable 1. The three tracks are arranged at intervals in the same direction. The gauge of the two outer tracks is a wide gauge, and the gauge of the inner track and one of the outer tracks is a narrow gauge. There is an annular track 11 in the turntable 1 for the railway locomotive 8 to rotate 180 degrees, and there are two narrow-gauge common rail conversion switches in the turntable 1. The wide gauge A outside the turntable is a common track; the other end of the turntable extends to three tracks connecting to the dead-end line outside the turntable. The three tracks are arranged at intervals in the same direction. The gauges of the two outer tracks A and B are wide gauges, and the gauge of the inner track D and the outer track B is the narrow-gauge line size. The outer track B is a common track. In this embodiment, the turntable system with a narrow-gauge common rail conversion type nested rail turntable 1 mainly includes the annular track 11 under the turntable, three tracks at the entrance end, narrow-gauge conversion switches inside the turntable, and three tracks at the dead-end end. For the refinement of the tracks, for the convenience of detailed description, the three tracks are arranged at intervals in the same direction. The gauges of the two outer tracks are both wide gauges, and the gauge of the inner track and one of the outer tracks is a narrow gauge. A set of two narrow-gauge conversion switches are respectively the narrow-gauge common rail conversion switch X90 and the narrow-gauge common rail conversion switch Y91. For further clear description, the three tracks outside the turntable 1 are respectively defined as the outer turntable wide gauge A7, the outer turntable wide gauge B5, and the outer turntable narrow gauge C6, and the outer turntable wide gauge B5, the outer turntable narrow gauge C6, and the outer turntable wide gauge A7 are arranged in sequence; the three tracks at the access end inside the turntable 1 are respectively defined as the inner turntable wide gauge A4, the inner turntable wide gauge B2, and the inner turntable narrow gauge C3, and the inner turntable wide gauge B2, the inner turntable narrow gauge C3, and the inner turntable wide gauge A4 are arranged in sequence. The three tracks at the dead-end end are respectively defined as the inner turntable wide gauge A4, the inner turntable wide gauge B2, and the inner turntable narrow gauge D14, and the inner turntable wide gauge B2, the inner turntable wide gauge B14, and the inner turntable wide gauge A4 are arranged in sequence. The railway narrow-gauge locomotive 8 enters the turntable 1 through the access end from the outer turntable wide gauge A7 and the outer turntable narrow gauge C6. After the turntable 1 rotates 180 degrees, it enters the outer nested rail railway tracks A7 and C6 of the turntable 1 through the narrow-gauge common rail conversion switch.

[0031] As an optimized solution of the embodiment of the present invention, please refer to Figure 4, each group of the narrow-gauge common-rail turnout includes a pair of guard rails and a pair of switch points for realizing the rail conversion of the narrow-gauge common rail. Each of the narrow-gauge turnouts also includes the connection between the inner-wide rail and the inner-narrow rail. The inner-wide rail of one of the narrow-gauge common-rail turnouts cooperates with the inner-narrow rail of another narrow-gauge turnout to provide rail conversion for the wheels of the railway locomotive 8. In this embodiment, the narrow-gauge turnout mainly consists of an inner-wide rail A4, an inner-wide rail B2, an inner-narrow rail C3, an inner-narrow rail D14, a pair of guard rails A12, a pair of guard rails B13, and a pair of switch points. The railway locomotive 8 can travel on the inner-wide rail A4 and the inner-narrow rail C3 and then be converted to travel on the inner-narrow rail D14 and the inner-wide rail B2, realizing the rail conversion of the narrow-gauge common rail from A4 to B2.

[0032] As an optimized solution of the embodiment of the present invention, please refer to Figure 3 , Figure 4 and Figure 5 , when the wide-gauge railway locomotive 8 turns around, the wheels of the wide-gauge railway locomotive 8 respectively fall on the inner-wide rail A4 and the inner-wide rail B2. Specifically, when the wide-gauge railway locomotive 8 turns around, the railway locomotive 8 enters the turntable 1 from the outer-wide rail A7 (common rail) and the outer-wide rail B5 outside the turntable 1. The railway locomotive 8 occupies the inner-wide rail A4 and the inner-wide rail B2. After the railway locomotive 8 rotates 180 degrees with the turntable 1, the inner-wide rail A4 and the inner-wide rail B2 symmetrically exchange positions and can be aligned with the outer-wide rail B5 and the outer-wide rail A7 connected outside the turntable 1. Then 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 8 turns around, the wheels of the narrow-gauge railway locomotive 8 respectively fall on the inner-wide rail A4 and the inner-narrow rail C3 of the turntable. Specifically, when the narrow-gauge railway locomotive 8 turns around, the railway locomotive 8 enters the turntable 1 from the outer-wide rail A7 (shared rail) and the outer-narrow rail C6 outside the turntable 1. The railway locomotive 8 uses the inner-wide rail A4 and the inner-narrow rail C3 of the turntable. After the railway locomotive 8 rotates 180 degrees with the turntable 1 and looks towards the direction of the railway buffer 10, the inner-wide rail A4 on the right side inside the turntable 1 is switched to the left side position inside the turntable 1, and the inner-narrow rail C3 is also switched to the right side position inside the turntable. The narrow-gauge shared-rail switch X90 and the narrow-gauge shared-rail switch Y91 inside the turntable 1 are also switched from the tail of the turntable 1 to the front of the turntable 1, and the narrow-gauge shared-rail switch X90 and the narrow-gauge shared-rail switch Y91 also switch positions with each other. At this time, the inner B2 of the narrow-gauge shared-rail switch X90 is butted with the outer-wide rail A7, and the inner D14 of the narrow-gauge shared-rail switch Y91 is butted with the outer-narrow rail C6. The railway locomotive 8 smoothly enters the outer-sheath rail railway through the narrow-gauge shared-rail switch X90 and the narrow-gauge shared-rail switch Y91, as Figure 5 shown. Preferably, after the railway locomotive 8 exits the turntable 1, since the shared-rail switch and the guard rail are symmetrically installed, the turntable 1 can be directly prepared to welcome the next railway locomotive 8 to turn around.

[0034] 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 10 outside the turntable 11.

[0035] As an optimized solution of the embodiment of the present invention, please refer to Figure 3 、 Figure 4 and Figure 5 , there are four inner tracks of the turntable. In this embodiment, four steel rails are adopted on the turntable 1. After the railway locomotive 8 turns around, 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.

[0036] 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.
