Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of track transportation, especially a point rail anti-jumping device. BACKGROUND
[0002] The stability of the railway point rail, as an important component of the track, directly affects the running safety of the train. When the high-speed train passes, the point rail is prone to jumping phenomenon due to the impact force and vibration between the wheel and the rail, which not only affects the smooth running of the train, but also may cause serious safety accidents. The anti-jumping devices on the market are mostly electrified devices, which have the problems of complex installation, high maintenance cost, etc. SUMMARY
[0003] In view of the above technical problems, the utility model provides a point rail anti-jumping device to solve the problems of complex installation and high maintenance cost of the existing anti-jumping device.
[0004] In order to achieve the above purpose, the technical scheme of the utility model is as follows:
[0005] A point rail anti-jumping device, comprising an anti-jumping plate, the anti-jumping plate is crimped on the sleeper, a elastic rod is transversely arranged on the anti-jumping plate, and the two ends of the elastic rod are connected to the point rails on the two sides of the sleeper through fasteners.
[0006] Further, it further comprises an adjusting assembly, the adjusting assembly is composed of an adjusting slot and a fixed wheel, the adjusting slot is arranged on the top of the anti-jumping plate, a plurality of adjusting holes are formed on the adjusting slot, a fastening bolt is installed on the adjusting hole, the elastic rod is arranged in the adjusting slot, and the fixed wheel is installed in the adjusting slot through the fastening bolt and is crimped on the elastic rod.
[0007] Compared with the prior art, the utility model has the beneficial effects that: the utility model has simple structure and is easy to install, the elastic rod can be self-adjusted in a large range, effectively compensates the geometric deformation caused by temperature difference, can also limit the point rail, avoids the jumping phenomenon of the point rail when the wheels of the high-speed train pass, improves the stability of the point rail operation, and the fixed wheel and the adjusting hole can be adjusted according to the needs of different sections and different types of sleepers, increasing the adaptability of the device. BRIEF DESCRIPTION OF DRAWINGS

[0009] Figure 2 It is a front view of the utility model.
[0010] In the figure:
[0011] 1, the jump plate; 2, the sleeper; 3, the elastic rod; 4, the fastener; 5, the frog; 6, the adjusting slot; 7, the fixed wheel; 8, the adjusting hole; 9, the fastening bolt; 10, the wheel. DETAILED DESCRIPTION
[0012] To make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the utility model is further explained in detail below in combination with specific implementation manners and with reference to the drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.
[0013] A frog anti-jumping device, including the jump plate 1, the jump plate 1 is pressed on the sleeper 2, the jump plate 1 is provided with the elastic rod 3 transversely, and the elastic rod 3 is connected on the frog 5 on both sides of the sleeper 2 through the fastener 4. The utility model has the advantages of simple structure, convenient installation, self-adjustment in a large range through the elastic rod 3, effective compensation of geometric deformation caused by temperature difference, limiting the frog 5, avoiding the phenomenon that the frog 5 jumps when the wheel 10 of high-speed train passes, and improving the stability of the frog 5 operation.
[0014] Further including the adjusting assembly, the adjusting assembly is composed of the adjusting slot 6 and the fixed wheel 7, the adjusting slot 6 is arranged at the top of the jump plate 1, a plurality of adjusting holes 8 are formed in the adjusting slot 6, the fastening bolt 9 is installed on the adjusting hole 8, the elastic rod 3 is arranged in the adjusting slot 6, and the fixed wheel 7 is installed in the adjusting slot 6 through the fastening bolt 9 and is pressed on the elastic rod 3. The fixed wheel 7 and the adjusting hole 8 can be adjusted according to the requirements of different road sections and different models of sleepers 2, and the adaptability of the device is increased.
[0015] When in use:
[0016] When the wheel 10 of high-speed train passes the frog 5, the frog 5 is effectively compensated under the action of the elastic rod 3, the jumping phenomenon is avoided, the installation position of the fixed wheel 7 in each adjusting hole 8 is adjusted appropriately for different models of sleepers 2, the outer circle of the fixed wheel 7 is preferably a concave arc surface, the elastic rod 3 can be better clamped, and the stability of the equipment operation is improved.
[0017] The above only describes the preferred embodiment of the utility model, and is not intended to limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
