Description

Technical Field

[0001] The utility model relates to the technical field of railway tracks, and in particular to a portable turnout roller adjustment ruler. Background Art

[0002] The roller assembly is a key component of the turnout point rail. Figure 3 , Figure 4 As shown, when the point rail is in a close contact state, the two rollers do not directly contact the bottom of the point rail, but maintain a gap of 1-2mm between the edges and corners of the bottom edge of the point rail to ensure that the point rail is supported by the slide bed under normal circumstances and maintains its stable position. However, when the point rail needs to be converted to a repelling state, the rollers play a key role. During the conversion of the point rail, the rollers begin to contact the point rail and lift it up. At this time, the rollers begin to support the point rail and convert the original sliding friction between the bottom of the point rail and the slide bed into rolling friction between the bottom of the point rail and the two rollers. The above-mentioned conversion greatly reduces the friction coefficient, thereby significantly reducing the resistance during the conversion of the point rail and reducing the pulling force; it not only helps to ensure the close contact of the point rail throughout the process, but also greatly improves the safety factor of the industrial and electrical joints of the turnout conversion system.

[0003] In order to avoid the negative impact caused by the malfunction of the turnout rollers, it is necessary to measure the height difference between the rollers, the height difference between the rollers and the slide bed, the gap between the point rail and the roller in a close fit state, etc. in daily turnout maintenance. Commonly used tools include spirit levels, angle rulers, gap rulers, steel rulers, etc. There are many tools, which are inconvenient to carry, and the procedures are complicated and time-consuming.

[0024] The portable turnout roller adjustment ruler of the utility model is further described below in conjunction with specific embodiments.

[0025] like Figure 1 , Figure 2 As shown, a portable switch roller 9 adjustment ruler includes an arc-shaped holder 1, a level ruler 2 is connected to the arc-shaped holder 1, a level measuring device 3 is provided on the level ruler 2, and a first measuring pad 4 and a second measuring pad 5 are provided at the bottom of the level ruler 2 in sequence along the arc-shaped holder 1. The second measuring pad 5 is higher than the first measuring pad 4, and the height difference matches the height difference between the two rollers 9 of the switch. In this embodiment, the arc-shaped holder 1 is semicircular, and the curvature is consistent with the curvature of the surface of the roller 9, so as to better fit the upper part of the roller 9. Figure 3 , 4 As shown, there are two rollers 9 in the prior art, of which the roller 9 near the point rail 11 is higher than the slide bed 12 by 2 mm, and the other roller 9 is higher than the slide bed 12 by 3 mm. Therefore, the present solution sets the corresponding height of the bottom surface of the first measuring pad 4 from the bottom surface of the level 2 by 2 mm, and the bottom surface of the second measuring pad 5 from the bottom surface of the level 2 by 3 mm.

[0026] like Figure 5 , Figure 6 , Figure 7As shown, when in use, the arc-shaped holder 1 is placed on the upper part of the roller 9, and then the bottom of the first measuring pad 4 or the second measuring pad 5 is overlapped and placed on the edge of the top surface of the slide table 12, and the horizontal measuring device 3 is observed to detect the horizontality. Since the height of the first measuring pad 4 or the second measuring pad 5 is a standard value set according to the height of the bottom surface of the pointed rail, when the horizontality does not meet the requirements, the height of the roller 9 needs to be adjusted until it is level. The height adjustment method of the roller 9 can refer to CN216809388U. An axial hole is provided on the side of the roller base 7, and a screw 8 is installed at the axial hole. A wedge-shaped inner push block is installed at the inner end of the screw 8. By loosening the bolts on the roller base 7 and then turning the screw 8, the screw 8 is used to push the wedge block to slide upward along the inclined surface, thereby pushing up the roller 9, and vice versa, the height of the roller 9 is lowered.

[0027] like Figure 2 As shown, the inner wall of the top of the arc-shaped holder 1 is flush with the bottom of the level 2. The bottom height of the level 2 is the top height of the roller 9. When manufacturing, it is only necessary to control the height of the first measuring pad 4 and the second measuring pad 5. In this embodiment, the arc-shaped holder 1, the level 2, the first measuring pad 4 and the second measuring pad 5 are all made of aluminum alloy.

[0028] like Figure 1 As shown, a receiving hole 6 is provided at the top of the arc-shaped level ruler 2, and the level measuring device 3 is installed in the receiving hole 6. The level measuring device 3 can be a bubble level or an electronic level. In this embodiment, a bubble level, specifically a tubular bubble level, is used, which can be directly embedded in the receiving hole 6.

[0029] like Figure 6 As shown, the thickness of the arc-shaped holder 1 is 1mm-2mm. The thickness of the arc-shaped holder 1 is used to measure the gap between the point rail 11 and the adjacent roller 9 when the point rail 11 is in close contact with the rail 10. If it is inserted just right, it is normal. Otherwise, if the gap is too large, it needs to be adjusted accordingly.

[0030] The surface of the level ruler 2 also has a length scale and / or the surface of the arc-shaped holder 1 also has an angle scale mark. In this embodiment, the surface of the level ruler 2 also has a length scale for measuring the width of the slide bed 12, the length of the roller 9, the distance between the center of the roller 9 and the slide bed 12, etc. (not shown in the figure). The surface of the arc-shaped holder 1 also has an angle scale mark for replacing a protractor to measure the angle of a workpiece (not shown in the figure).
