Description

Technical Field

[0001] This utility model relates to the field of railway construction technology, and in particular to a jointed track gap adjustment device. Background Technology

[0002] A rail gap refers to the gap left between the ends of two adjacent rails to accommodate thermal expansion and contraction. During rail laying, the size of the rail gap reserved at the rail joint must ensure that continuous blind gaps do not form when the rails are at the highest rail temperature in the region, and that the rail gap does not exceed the structural design rail gap value when the rails are at the lowest rail temperature in the region. Some existing jointed tracks exhibit uneven rail gaps due to various reasons, resulting in sections with gaps larger than the structural design gap in winter, and sections with three or more consecutive blind gaps in summer. To improve the quality of track equipment, measures to adjust rail gaps in sections are necessary. During operation, a steel ruler is used to control the rail gap. However, when workers use rail gap adjusters, they cannot accurately control the movement distance, leading to rail gaps that are too large or too small, causing rework and reducing work efficiency. Therefore, a device that can accurately and quickly adjust rail gaps is needed. Utility Model Content

[0024] like Figures 1 to 2 As shown, this utility model discloses a rail gap adjustment device for a jointed railway line, including a rail gap limiter and a hydraulic rail gap adjuster. The rail gap limiter is placed between the ends of two adjacent rails to facilitate the hydraulic rail gap adjuster to move the rails and adjust the rail gap between the two adjacent rails. The rail gap limiter includes a handle 1, a connecting plate 2, and an adjusting component 3. The end of the handle 1 along the length direction is connected to the top of the connecting plate 2. The adjusting component 3 is located at the end of the connecting plate 2 away from the handle 1. The adjusting component 3 includes multiple adjusting plates 4. The thickness of the multiple adjusting plates 4 decreases sequentially on the side away from the connecting plate 2 to facilitate limiting different rail gap widths.

[0025] In this embodiment, an adjustment plate 4 of appropriate thickness is selected according to the preset rail gap size. The adjustment plate 4 is placed between the ends of two adjacent rails. The rails are moved by the hydraulic rail gap adjuster so that the ends of the two adjacent rails are in close contact with the side wall of the adjustment plate 4. The rail gap between the two adjacent rails reaches the preset rail gap width. The position of the rails is then tightened, the hydraulic rail gap adjuster is removed, and the rail gap limiter is taken out. The rail gap at the next position is then adjusted. The rail gap width is limited by the adjustment plate 4, which improves the efficiency and accuracy of rail gap adjustment.

[0026] The hydraulic rail gap adjuster used in this application is the YTF-400 model product manufactured by Jinzhou Boyu Railway Equipment Co., Ltd.

[0027] The multiple adjustment plates 4 are all hollow structures and connected along the height direction. The length of each adjustment plate 4 is the same as the length of the connecting plate 2, and the height of each adjustment plate 4 is the same. The multiple adjustment plates 4 are nested in sequence.

[0028] In this embodiment, multiple adjustment plates 4 are nested in sequence. When an adjustment plate 4 with a preset thickness is required, the adjustment plates 4 located on the upper side of the adjustment plate 4 with the corresponding thickness are nested together, and the adjustment plates 4 located on the lower side of the adjustment plate 4 with the corresponding thickness are nested together. Finally, only the adjustment plate 4 with the corresponding thickness remains on the lower side of the connecting plate 2, so as to avoid multiple adjustment plates 4 on the lower side of the connecting plate 2 from affecting the snap-fit ​​effect.

[0029] In another possible embodiment, each adjusting plate 4 has connecting ears on both the left and right sides of its top horizontal direction. The connecting ears are vertically fastened to the side wall of the adjusting plate 4 near the top. A first threaded hole is provided near the top of the connecting ear, and a second threaded hole with the same diameter as the first threaded hole is provided at the corresponding position of the connecting plate 2. When rail gap clamping is required, an adjusting plate 4 of the corresponding thickness is selected, the first threaded hole and the second threaded hole of the adjusting plate 4 of the corresponding thickness are aligned, and the adjusting plate 4 of the corresponding thickness is fastened to the connecting plate 2 with bolts. Then, the adjusting plate 4 of the corresponding thickness is placed between the ends of two adjacent rails, and the rail gap is adjusted by moving the rails using a hydraulic rail gap adjuster. After the adjustment is completed, the adjusting plate 4 is released from the fastening of the connecting plate 2. Since the thickness of each adjusting plate 4 is different, multiple adjusting plates 4 are fastened to the connecting plate 2 respectively, which can limit rail gaps of multiple widths.

[0030] Each of the adjustment plates 4 has a slider on both outer walls along its length, and each of the adjustment plates 4 has a slide rail on both inner walls along its length to facilitate the lower adjustment plate 4 being inserted into the upper adjustment plate 4 along the slide rail.

[0031] In this embodiment, according to the preset rail gap width, an adjustment plate 4 of corresponding thickness is selected. The adjustment plates 4 located on the upper side of the adjustment plate 4 slide upward along the slide rail in sequence via the slider until all the adjustment plates 4 on the upper side of the adjustment plate 4 are embedded in the top adjustment plate 4; the adjustment plates 4 located on the lower side of the adjustment plate 4 slide upward along the slide rail in sequence via the slider until all the adjustment plates 4 on the lower side of the adjustment plate 4 are embedded in the adjustment plate 4; if the rail gap width between two adjacent rails is greater than the preset rail gap, the handle 1 is gripped, and the adjustment plate 4 is placed between the ends of the two adjacent rails. The rail gap is adjusted by moving the rails using a hydraulic rail gap adjuster. Make sure the ends of the two rails are tightly against the two side walls of the adjusting plate 4. After adjustment, fix the rails and remove the hydraulic rail gap adjuster and adjusting plate 4. If the rail gap width between two adjacent rails is smaller than the preset rail gap, first move the rails apart using the hydraulic rail gap adjuster to move them away from each other. Then, hold the handle 1 and place the adjusting plate 4 between the ends of the two adjacent rails. Then, move the rails apart using the hydraulic rail gap adjuster to adjust the rail gap so that the ends of the two rails are tightly against the two side walls of the adjusting plate 4. The rail gap adjustment of the two rails is then complete. Fix the rails and remove the hydraulic rail gap adjuster and adjusting plate 4.

[0032] The handle 1 has a T-shaped structure, and the vertical end of the handle 1 is fastened to the top center of the connecting plate 2.

[0033] In this embodiment, the handle 1 is configured as a T-shaped structure, and the vertical end of the handle 1 is fastened to the top center of the connecting plate 2, which avoids the staff having to bend over frequently to clamp the adjustment plate 4 and reduces the labor intensity of the staff.

[0034] In one possible embodiment, the handle 1 has a T-shaped structure, and the vertical end of the handle 1 is provided with an external thread structure. The top center of the connecting plate 2 is provided with a threaded hole. The internal thread of the threaded hole matches the external thread of the vertical end of the handle 1, which facilitates the threaded connection of the handle 1 and the connecting plate 2. After the rail gap adjustment is completed, the handle 1 can be unscrewed from the connecting plate 2 to reduce the space occupied by the adjustment device.

[0035] In another possible embodiment, unlike the above embodiment, the handle 1 is a telescopic structure, which makes it easy to adjust the length of the handle 1 according to the height of the staff, avoid the staff from bending over frequently, and reduce the labor intensity of the staff.

[0036] The connecting plate 2 is a square plate. The connecting plate 2 is located on the upper side of the adjusting plate 4 and has a hollow cavity that matches the size of the adjusting plate 4. The two inner walls of the hollow cavity along the length direction are symmetrically provided with slides to facilitate the adjusting plate 4 to slide upward into the connecting plate 2.

[0037] In this embodiment, according to the preset rail gap width, an adjustment plate 4 of corresponding thickness is selected. The adjustment plates 4 located on the upper side of the adjustment plate 4 slide upward along the slide rail by the slider until all the adjustment plates 4 on the upper side of the adjustment plate 4 are embedded in the top adjustment plate 4. The top adjustment plate 4 is then embedded upward along the slide rail on the inner wall of the connecting plate 2 into the connecting plate 2. The adjustment plates 4 located on the lower side of the adjustment plate 4 slide upward along the slide rail by the slider until all the adjustment plates 4 on the lower side of the adjustment plate 4 are embedded in the adjustment plate 4. At this time, only the adjustment plate 4 of the corresponding thickness remains on the lower side of the connecting plate 2. If the rail gap width of the two adjacent rails is greater than the preset rail gap, the handle 1 is gripped tightly, and the adjustment plate 4 is placed between the ends of the two adjacent rails, with the bottom of the connecting plate 2 aligned with the top of the rail. The rails are aligned closely together. The rail gap is adjusted by moving the rails using the hydraulic rail gap adjuster, so that the ends of the two rails are tightly against the two side walls of the adjustment plate 4. After adjustment, the rails are fixed and the hydraulic rail gap adjuster and adjustment plate 4 are removed. If the current rail gap width between two adjacent rails is smaller than the preset rail gap, the rails are first moved away from each other using the hydraulic rail gap adjuster. Then, the adjustment plate 4 is placed between the ends of the two adjacent rails by holding the handle 1 tightly, and the bottom of the connecting plate 2 is tightly against the top of the rail. The rail gap is then adjusted by moving the rails using the hydraulic rail gap adjuster, so that the ends of the two rails are tightly against the two side walls of the adjustment plate 4. The rail gap adjustment of the two rails is then completed. The rails are fixed and the hydraulic rail gap adjuster and adjustment plate 4 are removed.

[0038] The bottom of the connecting plate 2 is provided with a gasket.

[0039] A shim is placed at the bottom of the connecting plate 2 to prevent the connecting plate 2 from scratching the rail surface when it is in close contact with the rail surface.

[0040] The thickness difference between two adjacent adjustment plates 4 is 2 mm.

[0041] The connecting plate 2 is made of steel plate with a length of 40mm, a height of 40mm, and a thickness of 30mm.

[0042] Each of the adjustment plates 4 has a thickness marking engraved on its sidewall.

[0043] In this embodiment, a thickness mark is provided on the side wall of the adjustment plate 4 to facilitate the selection of the adjustment plate 4 with a preset thickness.

[0044] The length of the horizontal end and the length of the vertical end of the handle 1 are both 150mm.

[0045] In use, if the preset rail gap width is 8mm, select an 8mm thick adjustment plate 4. Check the rail gap width at the ends of two adjacent rails. If the rail gap width between two adjacent rails is greater than 8mm, place the 8mm thick adjustment plate 4 between the ends of the two adjacent rails. Then, use the hydraulic rail gap adjuster to move the rails so that the ends of the two rails are tightly against the two side walls of the 8mm thick adjustment plate 4. At this point, the rail gap between the two rails is 8mm. Fix the rails, then remove the hydraulic rail gap adjuster and take out the adjustment plate 4 to adjust the rail gap at the next position. If the rail gap width between two adjacent rails is less than 8mm, first use the hydraulic rail gap adjuster to move the rails away from each other so that the 8mm thick adjustment plate 4 can be placed between the adjacent rails. The hydraulic rail gap adjuster stops working between the two rails. After placing the 8mm thick adjustment plate 4 between the two adjacent rails, the hydraulic rail gap adjuster is restarted to move the rails so that the ends of the two rails are tightly against the two side walls of the 8mm thick adjustment plate 4. At this time, the rail gap between the two rails is 8mm. The rails are then fixed, and the hydraulic rail gap adjuster is removed, and the adjustment plate 4 is taken out to adjust the rail gap at the next position. If the preset rail gap width is 10mm, then a 10mm thick adjustment plate 4 is selected, and the rail gap is adjusted according to the above steps. This application selects an adjustment plate of appropriate thickness according to the preset rail gap width for rail gap adjustment, which solves the problem of inconsistent rail gap widths causing secondary rework and improves the accuracy and efficiency of rail gap adjustment.

[0046] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural transformations made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
