Description

Technical Field

[0001] This utility model relates to the field of track laying technology, and more specifically, to a multifunctional track gauge adjuster. Background Technology

[0002] With the rapid development of the rail transportation industry, the precision and stability of track geometry are increasingly important. As a key device ensuring accurate track geometry, the performance and adjustment efficiency of the gauge adjuster directly affect the safety and smoothness of train operation. Analysis of existing gauge adjusters reveals that traditional gauge struts can only widen the gauge but not narrow it. While gauge adjusters capable of narrowing the gauge have emerged in recent years, they are not suitable for use between the stock rail and switch rail at turnout points. At turnout points, due to the small gap between the stock rail and switch rail, existing gauge adjusters are inconvenient to install and prone to detachment during use. Utility Model Content

[0003] To overcome the shortcomings mentioned above, this utility model aims to provide a multi-functional gauge adjuster that can adjust the gauge between the main rail and the switch rail at the turnout.

[0004] A multifunctional track gauge adjuster includes a track gauge adjusting body and a support. The track gauge adjusting body includes a hydraulic cylinder, a support plate, and a top plate. The hydraulic cylinder is horizontally arranged. The support plate is fixed to the telescopic end of the hydraulic cylinder and perpendicular to the hydraulic cylinder. The top plate is fixedly sleeved on the fixed end of the hydraulic cylinder near the support plate. The lower end of the support plate is higher than the lower end of the top plate.

[0005] The support includes a base plate, a limiting frame, a pull rope, and a rail bottom hook. The base plate is located on the side of the top plate away from the support plate and abuts against the top plate. The limiting frame is located above the base plate and is used to fix the vertical position of the fixed end of the hydraulic cylinder. The rail bottom hook is located on the bottom of the rail away from the base plate. The pull rope is located below the rail and is used to connect the rail bottom hook and the base plate.

[0006] Furthermore, the width of the bottom plate near the top plate is greater than the width of the top plate, and supports are provided on both sides of the top plate. The supports are located on the outer side of the top plate, and connecting rings are provided on the supports. The pull rope is connected to the connecting rings.

[0007] Furthermore, the bottom of the rail hook has a receiving groove with an upper opening, and the pull rope is embedded in the receiving groove and passes horizontally through the rail hook.

[0008] Furthermore, the pull rope, rail bottom hook, and connecting ring are all detachably connected.

[0009] Furthermore, the hydraulic cylinder is a manual hydraulic cylinder.

[0010] Furthermore, the hydraulic cylinder includes a hydraulic pump, a threaded rod, an output shaft, a transmission rod, a structural sleeve, a structural rod, and a pressure relief knob. The support plate is fixedly connected to the output shaft, the top plate is fixedly sleeved on the threaded rod, and the limiting bracket is located outside the hydraulic pump.

[0011] Furthermore, the bottom of the hydraulic pump is in contact with the base plate, and the limiting frame includes an upright and a crossbar. The upright is fixed on both sides of the hydraulic pump, and the crossbar is located above the hydraulic pump and in contact with it. Both ends of the crossbar are connected to the upright.

[0012] Furthermore, the horizontal bars are provided on both sides of the upright.

[0013] Furthermore, the bottom of the hydraulic pump is spaced apart from the base plate, and the limiting frame includes an upright and a crossbar. The upright is fixed to both sides of the hydraulic pump, and the crossbar is located on the upper and lower sides of the hydraulic pump. The crossbar is connected to the upright and its height is adjustable.

[0014] Furthermore, the upright has an elongated adjustment through hole, and a connecting bolt is provided between the crossbar and the upright. The connecting bolt passes through the crossbar and the adjustment through hole, and the crossbar is connected to the upright through the connecting bolt.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model discloses a multi-functional track gauge adjuster, which includes a track gauge adjustment body and a support. In use, the fixed end of the hydraulic cylinder extends into the limiting frame of the support. The track gauge adjuster and the support are placed together on the side of the rail, with the base plate placed outside the sleeper, the top plate abutting against the base plate, and the support plate abutting against the track pad. The rail bottom hook passes under the rail and hooks onto the side of the rail base furthest from the track gauge adjuster, keeping the pull rope taut. As the hydraulic cylinder extends, the support plate remains in contact with the track pad. The top plate moves away from the pad, pushing the base plate and simultaneously pulling the rail closer to the support plate, thus adjusting the track gauge. Changing the orientation of the track gauge adjuster allows for both increasing and decreasing the track gauge. When it is necessary to decrease the track gauge between the main rail and the switch rail at a turnout, simply hook the rail bottom hook onto the rail base furthest from the track gauge adjuster, and pass the pull rope under both rails.

[0017] The multi-functional track gauge adjuster of this utility model is not only applicable to adjusting the ordinary track spacing, but can also be used to adjust the track gauge between the main rail and the switch rail at the turnout. It has a simple structure and is easy to use. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1:

[0028] like Figure 1 and Figure 2 As shown, the multi-functional track gauge adjuster in this embodiment includes a track gauge adjustment body and a support.

[0029] like Figure 3As shown, the main body for adjusting the track gauge includes a hydraulic cylinder, a support plate 1, and a top plate 2. The hydraulic cylinder is horizontally positioned, the support plate 1 is fixed to the telescopic end of the hydraulic cylinder and is perpendicular to the hydraulic cylinder, and the top plate 2 is fixedly sleeved on the fixed end of the hydraulic cylinder near the support plate 1. The lower end of the support plate 1 is higher than the lower end of the top plate 2. In use, the support plate 1 is located outside the track pad 21 and abuts against the track pad 21.

[0030] In this embodiment, the hydraulic cylinder is a manual hydraulic cylinder. Preferably, the hydraulic cylinder in this embodiment adopts a hydraulic device commonly used in hydraulic grapples. Specifically, the hydraulic cylinder includes a hydraulic pump 10, a threaded rod 11, an output shaft rod 12, a transmission rod 13, a structural sleeve 14, a structural rod 15, a fixed seat 23, and a pressure relief knob 16. The support plate 1 is fixedly connected to the output shaft rod 12, and the top plate 2 is fixedly sleeved on the threaded rod 11.

[0031] like Figure 4 As shown, the support in this embodiment includes a base plate 3, a limiting frame, a pull rope 4, and a rail bottom hook 5. The base plate 3 is located on the side of the top plate 2 away from the support plate 1 and abuts against the top plate 2. The limiting frame is located above the base plate 3 and is used to fix the vertical position of the hydraulic pump 10, thereby preventing the hydraulic cylinder from shaking during use. The rail bottom hook 5 is hooked onto the bottom of the rail 6 on the side away from the base plate 3. The pull rope 4 passes under the rail 6 and is connected to the rail bottom hook 5 and the base plate 3.

[0032] The width of the bottom plate 3 near the top plate 2 is greater than the width of the top plate 2, and the width of the bottom plate 3 near the top plate 2 is also greater than the width of the sleeper 22. Supports 7 are installed on both sides of the top plate 2, and the supports 7 are fixed to the top surface of the bottom plate 3. The supports 7 are located on the outer side of the top plate 2, and connecting rings 8 are installed on the supports 7. Pull ropes 4 are connected to the connecting rings 8, and the pull ropes 4 pass through both sides of the sleeper 22. The rail bottom hooks 5 hook onto the bottom of the rail 6. This arrangement makes the two pull ropes 4 parallel to each other, so that the tension of the pull ropes 4 on the rail bottom hooks 5 is perpendicular to the rail 6, which is beneficial for adjusting the track gauge.

[0033] Preferably, the rail bottom hook 5 is hook-shaped, with its top connecting to the upper surface of the rail bottom of the rail 6, and its bottom being horizontal. The bottom has an opening at the top of the receiving groove 9. The pull rope 4 is embedded in the receiving groove 9 and passes horizontally through the connection between the bottom and top of the rail bottom hook 5. This ensures that the bottom top surface of the rail bottom hook 5 is in close contact with the rail bottom of the rail 6 during use, preventing it from coming off the hook.

[0034] The pull rope 4 is detachably connected to the rail bottom hook 5 and the connecting ring 8. Specifically, in this embodiment, the pull rope 4 is a steel wire rope. The middle of the pull rope 4 passes through the connecting ring 8, and the two ends are joined together. A steel wire rope buckle is set near the connecting ring 8. The joined ends are embedded in the receiving groove 9 and pass through the bottom and top connection of the rail bottom hook 5. At least one steel wire rope buckle is installed on the side of the rail bottom hook 5 away from the connecting ring 8, so that the length of the pull rope 4 can be adjusted to keep the pull rope 4 taut.

[0035] In this embodiment, the fixing seat 23 at the bottom or end of the hydraulic pump 10 is in contact with the base plate 3. The limiting frame includes an upright 17 and a crossbar 18. The upright 17 is fixed to both sides of the hydraulic pump 10, and the crossbar 18 is positioned above and in contact with the hydraulic pump 10. Both ends of the crossbar 18 are connected to the upright 17. This confines the hydraulic pump 10 between the base plate 3 and the crossbar 18, preventing the hydraulic pump 10 from shaking when operating the structural rod 15, and not affecting the horizontal movement of the hydraulic pump 10. Preferably, crossbars 18 are provided on both sides of the upright 17, the base plate 3 is a steel plate, and the upright 17 and crossbar 18 are made of steel pipes. The upright 17 is welded to the base plate 3, and the crossbar 18 is bolted to the upright 17.

[0036] like Figure 5 and Figure 6 As shown, in Embodiment 2, the hydraulic pump 10 has a smaller outer diameter, resulting in a gap between the bottom of the hydraulic pump 10 and the base plate 3. The limiting frame includes an upright 17 and a crossbar 18. The upright 17 is fixed to both sides of the hydraulic pump 10, and the crossbar 18 is located on the upper and lower sides of the hydraulic pump 10. The crossbar 18 is connected to the upright 17 and its height is adjustable. Specifically, the upright 17 has elongated adjustment holes 19 on both its upper and lower parts. A connecting bolt 20 is provided between the crossbar 18 and the upright 17. The connecting bolt 20 passes through the crossbar 18 and the adjustment hole 19. The crossbar 18 is connected to the upright 17 through the connecting bolt 20, thereby allowing the height of the crossbar 18 to be adjusted, so that the hydraulic pump 10 is limited between the upper and lower crossbars 18.

[0037] The working principle of the multi-functional gauge adjuster in this embodiment is as follows:

[0038] In use, the fixed end of the hydraulic cylinder extends into the limiting frame of the support. The gauge adjuster and the support are placed together on the side of the rail 6, so that the base plate 3 is placed on the outside of the sleeper 22, the top plate 2 abuts against the base plate 3, and the support plate 1 abuts against the track pad 21. The rail bottom hook 5 passes under the rail 6 and hooks the bottom of the rail 6 away from the gauge adjuster, and the pull rope 4 is taut. By operating the structural rod 15, the output shaft rod 12 is extended. The support plate 1 is always in contact with the track pad 21. The top plate 2 moves away from the pad, thereby pushing the base plate 3 to move. At the same time, the pull rope 4 pulls the rail 6 closer to the support plate 1, thereby adjusting the gauge. Changing the placement direction of the gauge adjuster can increase or decrease the gauge. When it is necessary to decrease the gauge between the main rail and the switch rail at the turnout, simply hook the rail bottom hook 5 onto the bottom of the rail 6 away from the gauge adjuster, and the pull rope 4 passes under both rails 6.

[0039] The multi-functional gauge adjuster in this embodiment is not only applicable to adjusting the ordinary track spacing, but can also be used to adjust the gauge between the base rail and the switch rail at the turnout. It has a simple structure and is easy to use.

[0040] 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 utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
