Description

Technical Field

[0001] This utility model relates to the technical field of railway track maintenance equipment, and in particular to a track gauge adjustment device for a turnout switch section. Background Technology

[0002] Turnouts are a weak link in railway lines. Turnout tracks are easily damaged by wear and deformation. The loads from trains acting on the turnout tracks exert various additional forces, causing changes in track shape. These changes significantly reduce train throughput, alter the impact of train travel, increase maintenance frequency, and shorten the lifespan of turnout components. The switching section of the turnout is particularly difficult to maintain. In current technology, insulated gauge rods are used to maintain the track gauge. The gauge adjustment process for the turnout switching section involves first loosening the fasteners; then using a hydraulic puller to apply pressure to the guide rails at the switching section to adjust the gauge. However, the pressure applied by the hydraulic puller can easily deform the frame of the turnout switching section, causing changes in the track alignment and affecting normal train operation. Utility Model Content

[0003] The purpose of this invention is to solve the above-mentioned problems and provide a track gauge adjustment device for the turnout switching section.

[0004] The technical solution of this utility model is as follows: A track gauge adjustment device for a turnout switching section includes a left rod, a right rod, a middle sleeve, a pin, a middle nut, a side nut, and a shrinking component; the left and right rods are respectively inserted into the middle sleeve and connected to the middle sleeve by the pin, forming a detachable connection; the right end of the left rod has an external thread section; the external thread section is threaded into the middle nut; the middle nut is engaged with the middle sleeve; by pulling out the pin connecting the left rod and rotating the middle nut, the left rod can extend relative to the middle sleeve; at this time, it is ensured that the pin connecting the right rod is still in the position connecting the right rod and the middle sleeve; the extended left rod can ensure that the retaining grooves on both sides abut against the lower flanges of the guide rails on both sides, thereby increasing the track gauge between the guide rails on both sides to solve the problem of small track gauge in the turnout switching section; both the left and right rods have retaining grooves at their outer ends corresponding to the inner edge of the lower flange of the guide rail; the extended left rod is engaged with the middle sleeve. The right rod, through slot A, acts on the guide rail to widen the guide rail gauge. Both the left and right rods extend outwards from their lower sides via lead screws. The lead screws pass under the guide rail and threadedly engage with the side nut after passing through the shrinking component. The shrinking component has slot B corresponding to the inner edge of the lower wing plate of the guide rail. Rotating the side nut alone allows slot B to move inwards against the guide rail, engaging with slot A to clamp the guide rail. When addressing the large gauge issue in turnout sections, slots A and B on the left side can be positioned at an appropriate location on the left lead screw to clamp the left guide rail. This clamping position must ensure that the pin connects the left and right rods as a single unit, and that slot A on the right side is far from the inner edge of the lower wing plate of the right guide rail. Finally, continuously rotating the right side nut causes slot B on the right side to abut against the outer edge of the lower wing plate of the guide rail, and then the inner edge of the lower wing plate of the right guide rail moves closer to slot A on the right side until the guide rail gauge is reduced to a suitable gauge.

[0005] Preferably, an insulating section is provided in the middle of the right rod to prevent the left and right guide rails from being energized; the insulating section has the same structure as the insulating section of the insulating gauge rod.

[0006] Preferably, a flat washer and a spring washer fitted on the threaded section are provided between the intermediate nut and the intermediate sleeve to reduce wear on the end of the intermediate sleeve.

[0007] Preferably, all pins are vertically oriented; all pins can be inserted into the middle sleeve from top to bottom, reducing operational difficulty and ensuring the stability of the connection between the left rod, right rod and middle sleeve.

[0008] Preferably, the right end of the intermediate sleeve is provided with a pin hole A corresponding to the pin shaft; the left end of the right rod is provided with several pin holes B corresponding to the pin shaft; this eliminates the need to select the clamping position of the left guide rail on the left lead screw; the pin shaft connecting the right rod can be directly pulled out, causing the right rod to retract inward relative to the intermediate sleeve; after the right-side retaining groove A disengages from the inner edge of the lower flange of the guide rail, a suitable pin hole B is selected and inserted into the pin shaft, making the left rod, right rod, and intermediate sleeve a single unit; by rotating the right-side nut, the right-side retaining groove B moves inward against the outer edge of the lower flange of the guide rail; the process of solving the large gauge problem is now simpler.

[0009] Preferably, a flat washer and a spring washer fitted on the lead screw are provided between the tightening member and the edge nut to reduce wear on the tightening member.

[0010] Preferably, the shrinking component includes an integral upright plate and a flat plate; the buckle groove B is provided at the top of the upright plate; the upright plate is provided with a through hole that matches the lead screw; the flat plate abuts against the lower wing plate of the guide rail to ensure that the buckle groove B stably engages with the outer edge of the lower wing plate of the guide rail, and to ensure that the shrinking component can stably push the guide rail.

[0011] Furthermore, the shrink-fit component also includes two support ribs; the support ribs are symmetrically arranged on both sides of the flat plate; the ends of the support ribs are connected to the flat plate and the flat plate respectively; the support ribs support the flat plate to ensure that the flat plate and the lower flange of the guide rail are stably abutted.

[0012] The beneficial effects of this utility model are as follows: The track gauge adjustment device for the turnout switching section of this utility model has the following advantages:

[0013] (1) This utility model provides a device that can adjust the track gauge of the guide rail. The small track gauge phenomenon at the turnout switch is adjusted by turning the middle nut, and the large track gauge phenomenon at the turnout switch is adjusted by turning the side nut. The force applied to the guide rail at the switch position by this utility model will not exceed the bearing capacity of the guide rail, ensuring the normal operation of the train.

[0014] (2) All pins of this utility model can be inserted into the middle sleeve from top to bottom, reducing the difficulty of operation and ensuring the connection stability between the left rod, the right rod and the middle sleeve. Attached Figure Description

Detailed Implementation

[0019] Example 1: See Figure 1-3 A track gauge adjustment device for a turnout switching section includes a left rod 1, a right rod 2, an intermediate sleeve 3, a pin 4, an intermediate nut 5, an edge nut 6, and a shrinkage component 7. The left rod 1 and right rod 2 are respectively inserted into the intermediate sleeve 3 and connected to the intermediate sleeve 3 via the pin 4, forming a detachable connection. The right end of the left rod 1 has an external thread section 11; the external thread section 11 is threaded with the intermediate nut 5; the intermediate nut 5 is engaged with the intermediate sleeve 3. By pulling out the pin 4 connecting the left rod 1 and rotating the intermediate nut 5... It enables the left rod 1 to extend relative to the intermediate sleeve 3; at this time, it ensures that the pin 4 connecting the right rod 2 is still in the position connecting the right rod 2 and the intermediate sleeve 3; the extended left rod 1 can ensure that the buckle grooves A12 on both sides abut against the lower wing plates of the guide rails 0 on both sides, thereby increasing the track gauge between the guide rails 0 on both sides to solve the problem of small track gauge in the turnout section; both the left rod 1 and the right rod 2 have buckle grooves A12 at their outer ends that correspond to the inner edge of the lower wing plate of the guide rail 0; the extended left rod 1, in conjunction with the fixed right rod 2, can The guide rail 0 is opened by the action of the locking groove A12; the left rod 1 and the right rod 2 both extend the lead screw 13 from the lower side; the lead screw 13 passes under the guide rail 0; the lead screw 13 passes through the shrinking part 7 and is threaded into the side nut 6; the shrinking part 7 is provided with a locking groove B71 corresponding to the inner edge of the lower flange of the guide rail 0; by rotating the side nut 6 alone, the locking groove B71 can be moved inward against the guide rail 0, cooperating with the locking groove A12 to form a state of clamping the guide rail 0; this solves the problem of large track gauge in the turnout switching section. At this time, the left-side locking groove A 12 and locking groove B 71 can be positioned at a suitable position on the left-side lead screw 13 to clamp the left-side guide rail 0. This clamping position must ensure that the pin 4 connects the left rod 1 and the right rod 2 into a single unit, and that the right-side locking groove A 12 is away from the inner edge of the lower wing plate of the right-side guide rail 0. Finally, the right-side nut 6 is continuously rotated so that the right-side locking groove B 71 abuts against the outer edge of the lower wing plate of the guide rail 0. Then, the inner edge of the lower wing plate of the right-side guide rail 0 moves closer to the right-side locking groove A 12 until the track gauge of the guide rail 0 is reduced to a suitable track gauge.

[0020] Compared with the prior art, this utility model provides a device that can adjust the track gauge of the guide rail 0. The small track gauge phenomenon at the turnout switching part is adjusted by turning the middle nut 5, and the large track gauge phenomenon at the turnout switching part is adjusted by turning the side nut 6. The force applied to the guide rail 0 at the switching part by this utility model will not exceed the bearing capacity of the guide rail 0, ensuring the normal operation of the train.

[0021] An insulating section 21 is provided in the middle of the right rod body 2 to prevent the left and right guide rails 0 from being energized; the insulating section 21 has the same structure as the insulating section 21 of the insulating gauge rod.

[0022] A flat washer 8 and a spring washer 9, fitted on the threaded section, are provided between the intermediate nut 5 and the intermediate sleeve 3 to reduce wear on the end of the intermediate sleeve 3.

[0023] All pins 4 are vertically oriented; all pins 4 can be inserted into the middle sleeve 3 from top to bottom, reducing the difficulty of operation and ensuring the stability of the connection between the left rod 1, the right rod 2 and the middle sleeve 3.

[0024] The right end of the intermediate sleeve 3 is provided with a pin hole A 31 corresponding to the pin 4; the left end of the right rod 2 is provided with several pin holes B 22 corresponding to the pin 4. This eliminates the need to select the clamping position of the left guide rail 0 on the left lead screw 13; the pin 4 connecting the right rod 2 can be directly pulled out, causing the right rod 2 to retract inward relative to the intermediate sleeve; after the right-side retaining groove A 12 disengages from the inner edge of the lower wing plate of the guide rail 0, a suitable pin hole B 22 is selected and inserted into the pin 4, connecting the left rod 1, right rod 2, and intermediate sleeve 3 into one unit; by rotating the right-side edge nut 6, the right-side retaining groove B 71 moves inward against the outer edge of the lower wing plate of the guide rail 0; the process of solving the large track gauge problem is simpler. In this embodiment, there are two pin holes B 22.

[0025] A flat washer 8 and a spring washer 9, which are fitted on the lead screw 13, are provided between the tightening component and the edge nut 6 to reduce the wear of the shrinking component 7.

[0026] The shrinking component 7 includes an integral upright plate 72 and a flat plate 73; the buckle groove 71 is provided at the top of the upright plate 72; the upright plate 72 is provided with a through hole 721 that matches the lead screw 13; the flat plate 73 abuts against the lower wing plate of the guide rail 0 to ensure that the buckle groove 71 stably engages with the outer edge of the lower wing plate of the guide rail 0, and to ensure that the shrinking component 7 can stably push the guide rail 0.

[0027] The usage process of this embodiment includes the following steps:

[0028] ①Preparation process

[0029] Remove the guide rail 0 fasteners and the insulated gauge rod; remove the side nuts 6, shrink parts 7, flat washers 8, and spring washers 9 on both sides; pull out all the pins 4; insert the left rod 1 and the right rod 2 into the middle sleeve 3; hollow out the area below the guide rail 0 at the adjustment part so that the lead screws 13 on both sides can pass through the area below the guide rail 0; fasten the left side groove A 12 to the inner edge of the lower wing plate of the left guide rail 0, rotate the left side nut 6 to make the shrink parts 7 move closer to the left guide rail 0 until the left side groove A 12 and groove B 71 tightly hug the lower wing plate of the left guide rail 0;

[0030] ②Small gauge adjustment

[0031] Connect the right-side latch A12 to the inner edge of the lower wing plate of the right-side guide rail 0. Rotate the right-side edge nut 6 to bring the retractable part 7 closer to the right-side guide rail 0 until the right-side latch A12 and latch B71 tightly grip the lower wing plate of the right-side guide rail 0. Move the middle sleeve 3 so that pin hole A31 and pin hole B22 overlap. Pass the pin 4 through pin hole A31 and pin hole B22. Rotate the middle nut 5 to bring it closer to the middle sleeve 3. With the middle nut 5 against the middle sleeve 3, the left-side guide rail 0 moves to the left.

[0032] ③ Large gauge adjustment

[0033] The middle sleeve 3 is connected to the left rod 1 and the right rod 2 by the pin 4. The connection between the pin 4 and the right rod allows the right side buckle groove A 12 to disengage from the lower wing plate of the right guide rail 0 and maintain a certain distance, so that the buckle groove B 71 does not press against the outer edge of the lower wing plate of the right guide rail 0 after the right side nut 6 is rotated. Rotating the right side nut 6 causes the shrinking part 7 to move closer to the right guide rail 0 until the right side buckle groove B 71 presses against the outer edge of the lower wing plate of the right guide rail 0, pushing the right guide rail 0 to move to the left.

[0034] ④ Install the insulated track gauge tie rod and guide rail fasteners in sequence.

[0035] Example 2: Example 2 is basically the same as Example 1, and the similarities will not be repeated. The difference is that the shrinking part 7 also includes two support ribs 74; the support ribs 74 are symmetrically arranged on both sides of the plate 73; the ends of the support ribs 74 are connected to the plate 73 and the plate 73 respectively; the support ribs 74 support the plate 73 to ensure that the plate 73 and the lower wing plate of the guide rail 0 are stably abutted.

[0036] This invention can be applied not only to the gauge adjustment of the guide rail 0 in the turnout section, but also to the gauge adjustment of the guide rail 0 in the non-turnout section, i.e., ordinary track section.
