Description

Technical Field

[0001] This utility model belongs to the field of railway track maintenance, and specifically relates to a device for a top rail. Background Technology

[0002] A turnout is a track connection device installed on railway tracks to allow trains to switch from one track to another. At a turnout, there are stock rails and switch rails. If the gap between the stock rail and switch rail exceeds 2 millimeters, a vertical cut defect will occur. If a train passes through the turnout in this situation, the impact of the train on the switch rail, turnout connecting rods, and the switch machine can easily cause turnout failure and reduce the lifespan of the switch machine.

[0003] In the process of rectifying the vertical cutting defects of turnouts, it is necessary to adjust the distance between the switch rail and the stock rail. Currently, this is achieved by adjusting the switch rail, but there is a lack of relevant special equipment. Some operators now use hydraulic equipment to adjust the switch rail, but hydraulic equipment is expensive, bulky, and not suitable for long-term use on rails. Utility Model Content

[0004] The purpose of this invention is to provide a device for adjusting the tip rail, in order to solve the problems of lack of a dedicated device when adjusting the tip rail during the vertical cutting process, and the high cost and large size of hydraulic equipment, which are not conducive to long-term use.

[0005] To solve the above-mentioned technical problems, this utility model provides a device for a top rail, including a baffle assembly. The baffle assembly is a block structure. A threaded rotating part is provided on one side of the baffle assembly, and the threaded rotating part is provided with an internal thread. The threaded rotating part is threadedly connected to a top rail abutting screw, and the top rail abutting screw is provided with an external thread. The top rail abutting screw is used to abut the top rail, and the baffle assembly is used to abut the slide plate fixing bolt.

[0006] Furthermore, one end of the switch rail abutting screw is provided with a switch rail abutting part, which is used to abut the switch rail.

[0007] Furthermore, the switch rail abutment part has a block structure, with one side of the switch rail abutment part fixedly connected to the switch rail abutment screw, and the other side of the switch rail abutment part used to abut the switch rail.

[0008] Furthermore, the switch rail abutment part has a U-shaped structure, with a circular bottom through hole at the bottom and an annular abutment groove on one side of the switch rail abutment screw. The switch rail abutment part is set in the abutment groove through the bottom through hole, and the switch rail abutment part is rotatably connected to the switch rail abutment screw.

[0009] Furthermore, a rotating handle is provided on the side of the switch rail abutment screw opposite to the end where the switch rail abutment part is located.

[0010] Furthermore, the rotating handle passes through the switch rail abutting screw, and the axis of the rotating handle is perpendicular to that of the switch rail abutting screw. The rotating handle and the switch rail abutting screw are detachably connected.

[0011] Furthermore, several support assemblies are provided on the side of the baffle assembly away from the switch rail, and the supports are used to abut against the track slide plate.

[0012] Furthermore, the bracket assembly and the baffle assembly are rotatably connected.

[0013] The beneficial effects of the tip rail device provided by this utility model are as follows: Due to the inclusion of a baffle assembly, which is a block structure capable of being inserted into the gap between the track slide plate and its fixing bolts, the tip rail abutting screw rotates, abutting against the tip rail. Since the slide plate fixing bolts abut against the baffle assembly, the tip rail abutting screw pushes the tip rail towards the base rail, thus reducing the distance between the tip rail and the base rail. This component, utilizing existing track components, is a tool specifically designed to handle vertical cutting defects. Because the baffle assembly and tip rail abutting screw are readily available, low in cost, and small in size, they are suitable for long-term use on railway tracks. Attached Figure Description

[0018] To better understand the purpose, structure, and function of this utility model, the following description is in conjunction with the appendix. Figures 1 to 4 The present invention provides a more detailed description of a device for a top rail.

[0019] like Figures 1 to 4 As shown in the figure, a device for a center rail according to an embodiment of the present invention includes a baffle assembly 100. The baffle assembly 100 has a block-shaped structure. A threaded rotating part 110 with internal threads is provided on one side of the baffle assembly 100. The threaded rotating part 110 is threadedly connected to a center rail abutment screw 200 with external threads. The center rail abutment screw 200 abuts against a center rail 600, and the baffle assembly 100 abuts against a slide plate fixing bolt 800.

[0020] In use, the baffle assembly 100 is inserted into the gap between the track slide plate 900 and the slide plate fixing bolt 800. In current tracks, the gap between the track slide plate 900 and the slide plate fixing bolt 800 is typically a few millimeters. Therefore, a baffle assembly 100 with a thickness smaller than the gap width can be prepared in advance, allowing the baffle assembly 100 to be inserted. After the baffle assembly 100 is inserted into the track slide plate 900 and the slide plate fixing bolt 800, the threaded rotating part 110 faces upwards. Then, the switch rail abutment screw 200 is screwed into the threaded rotating part 110, causing the end of the switch rail abutment screw 200 near the switch rail 600 to gradually approach the switch rail 600. This is defined as the switch rail abutment screw 200 rotating clockwise. As the switch rail abutment screw 200 rotates, it gradually approaches the switch rail 600. Once the switch rail abutment screw 200 abuts against the switch rail 600, it is rotated clockwise again, and the switch rail abutment screw 200 will apply pressure to the switch rail 600. The baffle assembly 100 is abutted by the slide plate fixing bolt 800, and the baffle assembly 100 is stationary relative to the base rail 700. Therefore, as the switch rail abutment screw 200 rotates, the pressure applied to the switch rail 600 gradually increases. When the pressure applied to the switch rail 600 by the switch rail abutment screw 200 reaches a certain level, when the switch rail abutment screw 200 rotates forward again, the switch rail abutment screw 200 will push the switch rail 600 to move closer to the base rail 700, thereby achieving the purpose of adjusting the gap width between the base rail 700 and the switch rail 600.

[0021] In practice, a metal sheet with a thickness of less than 2 mm can be inserted into the base rail 700 and the switch rail 600 to determine whether the gap between the base rail 700 and the switch rail 600 has been adjusted properly.

[0022] After adjusting the gap between the base rail 700 and the switch rail 600, reverse the direction of rotation of the switch rail abutment screw 200. Once the switch rail abutment screw 200 disengages from the switch rail 600, there is no interaction force between the baffle assembly 100 and the slide plate fixing bolt 800. The center rail assembly can then be disassembled. For easier storage, the switch rail abutment screw 200 can be reversed off the threaded rotating part 110.

[0023] In order to increase the contact area between the switch rail abutting screw 200 and the switch rail 600 and improve the stability of their contact, a switch rail abutting part 300 is provided at one end of the switch rail abutting screw 200. The switch rail abutting part 300 is used to abut the switch rail 600.

[0024] In some embodiments, the switch rail abutment portion 300 is a block structure, and the switch rail abutment portion 300 is fixedly connected to the switch rail abutment screw 200. One side of the switch rail abutment portion 300 is fixedly connected to the switch rail abutment screw 200, and the other side of the switch rail abutment portion 300 is used to abut against the switch rail 600. The contact area between the block-shaped switch rail abutment portion 300 and the switch rail 600 is larger than the contact area between the switch rail abutment screw 200 and the switch rail 600, resulting in better stability.

[0025] In other embodiments, the switch rail abutment 300 has a U-shaped structure. A circular bottom through-hole 310 is provided at the bottom of the switch rail abutment 300, and an annular abutment groove 210 is provided on one side of the switch rail abutment screw 200. The switch rail abutment 300 is positioned in the abutment groove 210 through the bottom through-hole 310, and is rotatably connected to the switch rail abutment screw 200. During operation, the cavity of the switch rail abutment 300 can engage with the edge of the switch rail 600. When the switch rail abutment screw 200 rotates, the switch rail abutment 300 remains engaged in the abutment groove 210 and will not move forward or backward due to the threads of the switch rail abutment screw 200. The engagement of the switch rail abutment 300 with the switch rail 600 further improves operational stability.

[0026] To improve rotational comfort, a rotating handle 400 is provided on the side of the switch rail abutment screw 200 opposite to the end where the switch rail abutment part 300 is located. During operation, the switch rail abutment screw 200 can be rotated by rotating the handle 400.

[0027] The rotating handle 400 passes through the switch rail abutment screw 200, and the axis of the rotating handle 400 and the switch rail abutment screw 200 are perpendicular to each other. The rotating handle 400 and the switch rail abutment screw 200 are detachably connected. This design not only allows for effortless rotation of the switch rail abutment screw 200 using the lever principle, but also allows for removal of the switch rail abutment screw 200 from the threaded rotating part 110 by removing the rotating handle 400 and then rotating it.

[0028] In some embodiments, a plurality of support assemblies 500 are provided on the side of the baffle assembly 100 away from the switch rail 600, and the supports are used to abut against the track slide plate 900. The support assemblies 500 are rotatably connected to the baffle assembly 100. This design can further improve the stability of the baffle assembly 100 during operation.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
