Description

Technical Field

[0001] The utility model relates to the technical field of railway tracks, in particular to a movable center rail moving device. Background Art

[0002] Fixed switch has harmful space where the gauge line is interrupted, resulting in large vertical and lateral structural unevenness, which has a serious impact on the safety and stability of trains when passing switches.

[0003] In this regard, the prior art provides a movable heart rail, and the train enters the turnout connection part and transitions along the guide curve to the frog and guard rail unit. By moving the movable heart rail, the frog heart rail and the wing rail are closely attached to eliminate the harmful space of the fixed frog, and the train is guided into the main line or lateral direction, thereby improving the driving stability and safety.

[0004] As an important component of the movable heart rail frog, the sliding bed structure of the movable heart rail frog not only bears the rail parts and the train operation, but also provides a sliding platform for the sliding of the movable heart rail assembly. However, due to the existing movable heart rail frog pad structure and the fact that the bottom of the movable heart rail is mostly a non-machined surface, there is a large friction between the movable heart rail and the pad platform. During the back and forth movement of the movable heart rail, the fixed ends of the movable heart rail produce a large lateral deformation due to the friction, which is far from the ideal state without friction, resulting in insufficient displacement. The existence of insufficient displacement causes the actual linear shape of the movable heart rail frog to deviate from the theoretical position. If the insufficient displacement is large, it will affect the stability of the vehicle passing through the turnout and the comfort of the ride, and in serious cases, it will affect driving safety.

[0041] The following will describe the embodiments of the present utility model in detail with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways defined and covered by the following.

[0042] As Figures 1 - 10 shown, a movable switch rail moving device of this embodiment includes a table plate assembly 10, and also includes a movable switch rail fastener 20 and a fastener 30.

[0043] The table plate assembly 10 includes an upper table plate 11, a lower table plate 12, and a rolling support assembly 13. The upper table plate 11 is used for firmly connecting with the movable switch rail assembly 100. That is to say, the movable switch rail assembly 100 is detachably fixed on the upper table plate 11.

[0044] The lower platen 12 is disposed below the upper platen 11, and the lower platen 12 is fixedly welded to the bottom floor. The rolling support assembly 13 is disposed between the upper platen 11 and the lower platen 12.

[0045] The upper platen 11 and the lower platen 12 can abut against each other to transmit force, or separate from each other and move out of position under the rolling support of the rolling support assembly 13.

[0046] It can be understood that by arranging the movable point rail assembly 100 on the upper platen 11 and arranging the rolling support assembly 13 between the upper platen 11 and the lower platen 12, when the movable point rail assembly 100 is toggled, the upper platen 11 moves accordingly. At this time, the rolling of the rolling support assembly 13 between the upper platen 11 and the lower platen 12 can reduce the frictional resistance between the upper platen 11 and the lower platen 12, which makes the force small when toggling the movable point rail assembly 100 and not easy to deform, so that it will not rebound after reaching the position, which is beneficial to ensuring the displacement stroke of the movable point rail assembly 100. And after the movable point rail assembly 100 moves to the preset position, the upper platen 11 and the lower platen 12 can abut against each other to transmit force. At this time, the rolling support assembly 13 does not need to bear the weight and vibration when the train passes by, thus avoiding damage to the rolling support assembly 13.

[0047] In some embodiments, a walking groove 12a is provided on the upper surface of the lower platen 12. The rolling support assembly 13 is disposed on the upper platen 11. The roller 132 of the rolling support assembly 13 can abut against the bottom surface of the walking groove 12a and can roll along the width direction of the walking groove 12a.

[0048] It can be understood that the upper surface of the lower platen 12 is the surface facing the upper platen 11. The walking groove 12a is a groove structure. The rolling support assembly 13 is disposed on the lower surface of the upper platen 11 and can move along with the upper platen 11. Among them, the roller 132 of the rolling support assembly 13 can be spherical or cylindrical.

[0049] In some embodiments, along the width direction of the walking groove 12a, the bottom surface of the walking groove 12a includes a first support surface 121a, a second support surface 121b, and a third support surface 121c arranged in sequence. Among them, the height of any point on the second support surface 121b is higher than that of the first support surface 121a and the third support surface 121c.

[0050] When the roller 132 of the rolling support assembly 13 is on the first support surface 121a or the third support surface 121c, the upper platen 11 and the lower platen 12 abut. When the roller 132 of the rolling support assembly 13 is supported on the second support surface 121b, the upper platen 11 and the lower platen 12 are separated.

[0051] Please refer to Figures 8 - 10 It can be understood that when the roller 132 of the rolling support assembly 13 is supported on the second support surface 121b, the upper platen 11 is separated from the lower platen 12, and the upper platen 11 and the lower platen 12 are supported by the rolling support assembly 13, that is, the two are in rolling friction. When the roller 132 of the rolling support assembly 13 is on the first support surface 121a or the third support surface 121c, the upper platen 11 and the lower platen 12 are in contact, and the upper platen 11 and the lower platen 12 directly transmit force.

[0052] Since the weight of the train is very large when it passes, it is supported by the rolling support assembly 13, which is easily damaged. In this embodiment, in the process of pulling the movable heart rail assembly 100, it can be supported between the upper platen 11 and the lower platen 12 by the rolling support assembly 13, thereby reducing friction and reducing the deformation of the movable heart rail assembly 100 along its own length direction. After the movable heart rail assembly 100 is in place, the roller 132 of the rolling support assembly 13 is separated from the second support surface 121b, and the rolling support assembly 13 is not subjected to force at this time. Instead, the force is directly transmitted through the abutting upper platen 11 and the lower platen 12, thereby protecting the rolling support assembly 13 from damage.

[0053] It should be noted that at the beginning or end of the stroke of the movable heart rail assembly 100 , there may be sliding friction between the upper platen 11 and the lower platen 12 , and at this time, the rolling support assembly 13 is not supported on the second support surface 121 b .

[0054] Please refer to Figures 2 to 3 In some embodiments, the second support surface 121b includes a first guide surface 1211a and a second guide surface 1211b. Along the width direction of the walking groove 12a, the first guide surface 1211a and the second guide surface 1211b each have a first end and an opposite second end. The first guide surface 1211a gradually rises from the first end to the second end, the first end of the second guide surface 1211b is connected to the second end of the first guide surface 1211a, and the second guide surface 1211b gradually decreases from the first end to the second end.

[0055] It can be understood that the first guiding surface 1211a and the second guiding surface 1211b form a structure that is high in the middle and low at both ends. When the rolling support assembly 13 is supported between the first guiding surface 1211a and the second guiding surface 1211b and continues to move, a certain acceleration can be provided through either the first guiding surface 1211a or the second guiding surface 1211b to offset the resistance at the end of the switching travel of the movable point rail assembly 100. At the same time, the above acceleration can provide a certain inertia, better ensure the displacement of the movable point rail assembly 100, and reduce the deformation of the movable point rail assembly 100 during this movement process.

[0056] In some embodiments, the first guiding surface 1211a and the second guiding surface 1211b are inclined surfaces with the same slope.

[0057] In some embodiments, along the width extension direction of the running groove 12a, at least two groups of the running grooves 12a are arranged at intervals on the upper surface of the lower platen 12. Along the length extension direction of each running groove 12a, at least two of the rolling support assemblies 13 are arranged at intervals.

[0058] That is to say, at least four rolling support assemblies 13 are provided. Thus, stable support for the upper plate body is provided.

[0059] It can be understood that by arranging at least two groups of running grooves 12a at intervals, there is an interval area between the two groups of running grooves 12a. It can be understood that the above interval area can contact the upper platen 11 to transmit force, thereby better providing support for the movable point rail assembly 100. In some embodiments, the upper platen 11 has an installation area for installing the movable point rail assembly 100, and the installation area at least partially overlaps vertically with the interval area between the two groups of running grooves 12a.

[0060] Please refer to Figures 4 - 5 , in some embodiments, an installation groove 11a is provided on the lower surface of the upper platen 11, and the rolling support assembly 13 is arranged in the installation groove 11a. It can be understood that the installation groove 11a is located at the installation area of the upper platen 11. By providing the installation groove 11a, the dimension of the rolling support assembly 13 protruding from the lower surface of the upper platen is reduced, that is, to a certain extent, to avoid the running groove 12a being too deep and affecting the overall strength of the lower platen 12. In some embodiments, the rolling support assembly 13 includes an installation table 131 and a roller 132, the installation table 131 is fastened to the upper platen 11, and the roller 132 is rotatably arranged on the installation table 131.

[0061] Among them, the ball and the installation table 131 form a freely movable universal ball structure.

[0062] The structure of the mounting table 131 is not limited. For example, it includes the mounting table 131 part and the lug parts on both sides thereof, and is fixedly installed by the fastener 30 passing through the lugs.

[0063] Please refer to Figure 1 and Figure 7 In some embodiments, the movable point rail moving device further includes a movable point rail clamping member 20 and a fastener 30.

[0064] Two sets of the movable point rail clamping members 20 are provided. The first end of one set of the movable point rail clamping members 20 is fixedly fastened to the upper platen 11 by the fastener 30, and the second end is used to be fixedly fastened to the movable point rail assembly 100 by the fastener 30. The first end of the other set of the movable point rail clamping members 20 is fixedly fastened to the lower platen 12 by the fastener 30, and the second end is used to be fixedly fastened to the movable point rail assembly 100 by the fastener 30. In this way, the movable point rail assembly 100 and the upper platen 11 form an integral body through the movable point rail clamping member 20 and the fastener 30, and bear the force together when the train passes. At the same time, the lateral stability during the movement of the movable point rail assembly is ensured.

[0065] In some embodiments, the part of the movable point rail clamping member 20 for contacting the movable point rail assembly 100 is conformable to the movable point rail assembly 100. Thereby, the integrity is improved, and relative vibration is avoided when being subjected to an external force, which affects the service life and safety. Among them, the movable point rail clamping member 20 can be obtained by stamping a strip-shaped metal piece.

[0066] Through holes 20a are formed at the second ends of both sets of the movable point rail clamping members. A fastener 30 is used to sequentially pass through the through holes 20a at the second ends of one set of the movable point rail clamping members 20, the movable point rail assembly 100, and the through holes 20a at the second ends of the other set of the movable point rail clamping members 20 and be fastened. In this way, the gasket structure during the installation of the fastener 30 can be replaced. Among them, the fastener 30 can be a bolt assembly.

[0067] Among them, the movable point rail assembly 100 includes a long point rail 101, a short point rail 102, and a spacer 103 located between the long point rail 101 and the short point rail 102.

[0068] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
