Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of railway track maintenance equipment, in particular to a turnout track gauge fine-adjusting track changer. Background Art
[0002] A turnout is a line connection device that allows a locomotive to transfer from one track to another. It is usually laid in large quantities at stations and marshaling yards. Turnouts play an important role on railway lines. Fine-tuning the track gauge is an important step in line fine-tuning operations. It requires adjustments not only at non-turnout locations but also at turnout locations. Due to the different layout of rails at turnouts, a special turnout changer is required to adjust the track gauge.
[0003] If a general track diverter is used to adjust the track gauge at the turnout, such as the original track diverter or the inclined rail diverter, both of them apply a lateral force to the rail in the diverting direction at the bottom of the rail, so that the rail moves, and after measuring with a track gauge, the bolts are tightened to complete the diverting operation. There are two problems: 1. Excessive force or insufficient force during diverting will result in over-diversion or under-diversion; 2. The point of force applied during diverting is at the bottom of the rail, which makes the rail easy to tilt, resulting in a false track gauge, giving people a false impression. After tightening the bolts, a deviation of +1mm or -1mm will appear, which makes it more difficult to achieve the current requirement of controlling the track gauge within ±0.5mm.
[0004] Therefore, it is necessary to design a new type of diverter to improve the adjustment accuracy and operation convenience, thereby improving the operational efficiency of line diversion. Utility Model Content

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the scope of implementation of the present invention is not limited thereto.
[0026] like Figure 1 , Figure 2 , Figure 3 As shown, the turnout gauge fine-adjusting device of this embodiment includes a base 1, a groove 11 for sleeved on the top of the gauge block is provided at the bottom of the base 1, the width of the groove 11 is the same as the width of the gauge block, a limit plate 12 for abutting against the end of the gauge block close to the rail is provided at the front end of the groove 11, a pad 2 is provided at the bottom of the rear end of the groove 11, a push rod 3 is provided on the upper side of the base 1, the push rod 3 is movably connected to the base 1, and a top plate 4 for pushing the rail forward is provided at the front end of the push rod 3.
[0027] The gauge block of the present application is a part used to adjust the distance between train rails. It is arranged on the side of the rail, connected to the sleeper by bolts, and is also provided with fasteners, etc. The present application uses the gauge block at the turnout as a reference for limiting and adjusting the gauge. Specifically, after removing the fasteners and replacing the relevant parts, the track changer of this embodiment is sleeved on the top of the gauge block, the limit plate 12 contacts the gauge block from one side, and the pad 2 contacts the gauge block from the other side, so that the base 1 cannot move, and then the push rod 3 above the base 1 is extended to a certain length to push the rail forward.
[0028] Furthermore, a relief groove 13 for avoiding the bolt hole on the gauge block close to the rail is provided in the groove 11 of the base 1. A second relief groove 5 for avoiding the bolt hole on the gauge block far from the rail is provided on the pad 2. The relief groove 13 and the second relief groove 5 prevent the base from interfering with the upper end face or bolt of the gauge block.
[0029] Furthermore, the distance between the pad 2 and the limit plate 12 is equal to the length of the gauge block in the direction perpendicular to the rail. In order to adapt to gauge blocks of different specifications, the pad 2 is slidably connected to the base 1 in the direction perpendicular to the rail, and then a locking screw for locking the pad 2 is provided on the base 1, so that the pad 2 is locked after the base is buckled on the gauge block.
[0030] Furthermore, a hexagonal nut is provided at the tail end of the push rod 3 , and two nuts 6 are fixedly provided on the upper side of the base 1 , and the push rod 3 is threadedly connected to the nuts 6 .
[0031] The track diverter of the present application uses a track gauge to measure the track gauge and then adjust it. After the track gauge is well controlled, construction workers can participate in replacing the base and gusset plate, which greatly improves the work efficiency and the work quality, so that the number of workers required for the work is reduced by at least two compared with the existing technology, and the work quality can be well controlled.
