Turnouts play a vital role on railway lines, maximizing their throughput capacity. A diesel turnout grinder is specialized equipment used to polish railway turnouts. Because turnouts are exposed to the elements year-round, they are susceptible to various natural factors, including wind, sun, rain, snow, and frost. These can cause rust, dulling, and unevenness on the turnout surface, necessitating the use of a diesel turnout grinder.

[0003] The wheelbase of the running wheels on the internal combustion turnout grinding machine in the prior art is fixed and cannot be adjusted, so that the equipment cannot perform grinding work on tracks of different widths, reducing the practicality of the turnout grinding machine.

[0019] In the description of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are intended only to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention. The following describes various embodiments of the present invention in detail with reference to the accompanying drawings.

[0020] See also Figures 1 to 4 The utility model preferably provides a technical solution: a wheelbase adjustment mechanism for an internal combustion turnout grinder, including a mounting frame 1, the upper surface of the mounting frame 1 is penetrated by a mounting hole 11; a running rod 2, the running rod 2 is fixed on the inner wall of the mounting hole 11; a grinding trolley 3, the grinding trolley 3 is arranged on the running rod 2 and is slidingly connected to the running rod 2; a grinder body 31, the grinder body 31 is arranged on the grinding trolley 3 and is used to grind the turnout; it also includes a fixed frame 4, the fixed frame 4 is arranged at the bottom of the mounting frame 1 and is slidingly connected to the bottom of the mounting frame 1, four fixed frames 4 are provided and distributed in a rectangular array, each fixed frame 4 is provided with a running wheel 5, and a driving component 6 for driving the fixed frames 4 on both sides to move closer to each other is installed on the mounting frame 1.

[0021] According to the utility model, when the wheelbase of the running wheel 5 needs to be adjusted, the staff drives the fixing frames 4 on both sides to move closer to or away from each other through the driving assembly 6, thereby adjusting the distance between the running wheels 5 on both sides, which is conducive to grinding work on tracks of different widths and improves the practicality of the switch grinder.

[0022] Furthermore, two symmetrically arranged adjustment holes 12 are provided on the upper surface of the mounting frame 1; the drive assembly 6 includes a double-headed screw 61, which is provided on the side wall of the mounting frame 1 and is rotatably connected, and the double-headed screw 61 is provided with two sections of threads with opposite rotation directions and equal pitches; a handwheel 62, the handwheel 62 is fixed at the end of the double-headed screw 61 away from the mounting frame 1; and also includes an adjustment block 63, the adjustment block 63 is slidingly connected to the inner wall of the adjustment hole 12, four adjustment blocks 63 are provided and are respectively fixed to the upper surfaces of the four fixing frames 4, and the adjustment blocks 63 on both sides are respectively threadedly connected to the two sections of threads on the double-headed screw 61.

[0023] Combine Figure 2 As shown, the staff rotates the double-headed screw 61 through the hand wheel 62. Since the adjustment blocks 63 on both sides are threadedly connected to the two sections of threads on the double-headed screw 61, the adjustment blocks 63 are slidingly connected to the inner wall of the adjustment hole 12. Therefore, the adjustment blocks 63 on both sides drive the fixing frame 4 to move closer to or away from each other along the axial direction of the double-headed screw 61, thereby adjusting the wheelbase of the running wheel 5.

[0024] Furthermore, a limiting assembly 7 is provided on the double-headed screw 61 and is used to limit the double-headed screw 61 ; the limiting assembly 7 includes a limiting nut 71 which is sleeved on the double-headed screw 61 and threadedly connected to the double-headed screw 61 .

[0025] like Figure 3 As shown, after adjusting the distance between the running wheels 5, the staff needs to tighten the limit nut 71 so that the side wall of the limit nut 71 is pressed against the side wall of the mounting frame 1, thereby limiting the circumferential rotation of the double-headed screw 61 and reducing the probability of the automatic rotation of the double-headed screw 61 causing the wheelbase of the running wheel 5 to change.

[0026] Furthermore, the limiting assembly 7 further includes an annular rubber sheet 72 sleeved on the double-headed screw 61, and the annular rubber sheet 72 is arranged between the mounting frame 1 and the hand wheel 62, as shown in FIG. Figure 3 As shown, the annular rubber sheet 72 is made of rubber material, and its surface has a large friction coefficient. The side wall of the limiting nut 71 cooperates with the side wall of the mounting frame 1 and presses against the annular rubber sheet 72, thereby increasing the friction between the side wall of the limiting nut 71 and the side wall of the mounting frame 1, and enhancing the limiting effect of the limiting nut 71 on the double-headed screw 61.

[0027] Furthermore, a mounting groove 13 is provided on the side wall of the mounting frame 1 away from the hand wheel 62, and a linkage assembly 8 is provided in the mounting groove 13 and is used to simultaneously rotate the double-headed screws 61 on both sides; the linkage assembly 8 includes a pulley 81, which is provided with two pulleys 81 and is fixedly mounted on the double-headed screws 61 on both sides; and also includes a transmission belt 82, which is mounted on the two pulleys 81, as shown in FIG. Figure 4As shown, the double-headed screws 61 on both sides are connected by a transmission belt 82 and a pulley 81, so that the staff only needs to rotate the handwheel 62 on one side to drive the double-headed screws 61 on both sides to rotate at the same time, which is conducive to keeping the front and rear wheelbases consistent.

[0028] Furthermore, the side wall of the mounting frame 1 is provided with a protective plate 9 for closing the mounting slot 13, as shown in FIG. Figure 2 、 4 As shown, the protective plate 9 closes the installation slot 13, thereby protecting the linkage assembly 8 in the installation slot 13 and reducing the probability of external dust and debris entering the installation slot 13 and damaging the linkage assembly 8.

[0029] Furthermore, the upper surface of the mounting frame 1 is provided with scale lines 10 for observing the wheelbase of the running wheels 5 on both sides after adjustment, such as Figure 1 、 2 As shown, the setting of the scale lines 10 allows the staff to judge the distance between the running wheels 5 on both sides through the scale lines 10, which is conducive to accurately adjusting the wheelbase of the running wheels 5 on both sides.

[0030] In the present invention, unless otherwise clearly specified and limited, terms such as "install", "connect", "connect", and "fix" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection. There are many ways of detachable installation, for example, it can be through plug-in and snap-fitting, or through bolt connection, etc.
