Abstract
Description
Technical Field
[0001] This utility model relates to the field of metallurgical equipment technology, specifically a turnout rail heat treatment guide constraint device. Background Technology
[0002] Turnouts are crucial components of railway lines, guiding trains to change direction. Turnout rails, as vital elements in turnout manufacturing, directly impact railway transport safety and operational efficiency. By the end of 2013, China's railway operating mileage had exceeded 100,000 kilometers, with approximately 180,000 sets of turnouts in use. Due to the harsh operating conditions and complex stresses, turnout rails have long been one of the weakest links in railway lines, with a lifespan generally only one-fifth that of ordinary rails, and a throughput of only about 150 million tons. The average lifespan of ordinary turnout rails used on the Daqin Railway, with an annual transport capacity of 400 million tons, is less than six months, severely restricting railway transport efficiency and operational safety; simultaneously, it significantly increases maintenance costs for railway engineering departments and the labor intensity of workers. Therefore, improving the performance of turnout rails is essential to meeting the needs of my country's railway construction and development.
[0003] Therefore, it is imperative to develop turnout rails with good economic efficiency and performance. Relevant Chinese standards require that key components of turnout rails undergo heat treatment before use.
[0004] Existing turnout rail heat treatment guiding restraint devices often experience turnout rail jamming during operation. To solve this technical problem, a turnout rail heat treatment guiding restraint device is proposed. Utility Model Content
[0005] The purpose of this invention is to provide a turnout rail heat treatment guide constraint device to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A heat-treated guide constraint device for turnout rails includes: a mounting base; a short-leg side constraint plate and a long-leg side constraint plate of the turnout rail disposed on the mounting base; a travel channel is formed between the short-leg side constraint plate and the long-leg side constraint plate of the turnout rail; the turnout rail is disposed in the travel channel; a guide wheel on the constraint device is disposed on the short-leg side constraint plate of the turnout rail near the travel channel; the guide wheel on the constraint device is inclined; the guide wheel on the constraint device is used to abut against the side wall of the turnout rail for guiding the turnout rail; a guide wheel on the constraint device is also disposed on the long-leg side constraint plate of the turnout rail near the travel channel, and the guide wheel on the constraint device on the long-leg side constraint plate of the turnout rail is also inclined.
[0008] As a further embodiment of this utility model: a mounting shaft is provided at the middle position of the guide wheel on the constraint device, and the mounting shaft is rotatably installed in the mounting hole on the adjacent short leg side constraint plate or long leg side constraint plate of the turnout rail.
[0009] As a further improvement of this utility model, the tilt angle of the guide wheel on the constraint device is 45°.
[0010] As a further embodiment of this utility model: the driving mechanism includes two sets of driving components disposed on both sides of the mounting base, and the two sets of driving components are respectively connected to the short leg side constraint plate or the long leg side constraint plate of the adjacent turnout rail.
[0011] As a further embodiment of this utility model: the drive assembly for moving the short leg side constraint plate of the turnout rail includes a threaded rod rotatably mounted on a mounting base. The end of the threaded rod near the short leg side constraint plate of the turnout rail is provided with an external thread. The external thread of the threaded rod engages with a threaded hole on a connector. The connector is fixedly mounted on the adjacent short leg side constraint plate of the turnout rail. The assembly also includes a drive assembly for rotating the threaded rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by setting guide wheels on both sides of the walking channel formed between the short leg side constraint plate and the long leg side constraint plate of the turnout rail, the turnout rail can be guided smoothly, reducing the phenomenon of the turnout rail getting stuck during movement, ensuring that the heat treatment process can be carried out smoothly.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0022] Example 1
[0023] Please see Figures 1-2 The present invention provides a structural diagram of a turnout rail heat treatment guiding constraint device according to Embodiment 1. The turnout rail heat treatment guiding constraint device includes: a mounting base 5, a turnout rail short leg side constraint plate 1 and a turnout rail long leg side constraint plate 4 disposed on the mounting base 5, forming a travel channel between the turnout rail short leg side constraint plate 1 and the turnout rail long leg side constraint plate 4, the turnout rail 2 being disposed in the travel channel, a guide wheel 3 on the constraint device being disposed near one end of the turnout rail short leg side constraint plate 1, the guide wheel 3 on the constraint device being inclined; the guide wheel 3 on the constraint device being used to abut against the side wall of the turnout rail 2 for guiding the turnout rail 2; the turnout rail long leg side constraint plate 4 also being disposed near one end of the travel channel, and the guide wheel 3 on the constraint device on the turnout rail long leg side constraint plate 4 being inclined as well.
[0024] The mounting base 5 is also provided with a driving mechanism for driving the short leg side restraint plate 1 and the long leg side restraint plate 4 of the turnout rail away from each other. The driving mechanism makes the short leg side restraint plate 1 and 4 of the turnout rail move away from each other, so that when an accident occurs, the turnout rail 2 can be removed from between the short leg side restraint plate 1 and the long leg side restraint plate 4 of the turnout rail in a timely manner.
[0025] This invention uses guide wheels 3 on both sides of the walking channel formed between the short leg side constraint plate 1 and the long leg side constraint plate 4 of the turnout rail to guide the turnout rail 2, allowing it to pass smoothly and reducing the possibility of jamming during movement. This ensures that the heat treatment process can proceed smoothly. If a malfunction causes the turnout rail 2 to jam, the drive mechanism will move the short leg side constraint plate 1 and the long leg side constraint plate 4 away from each other, thus allowing the jammed turnout rail 2 to be removed quickly.
[0026] like Figure 1 As shown, in a preferred embodiment of the present invention, a mounting shaft is provided at the middle position of the guide wheel 3 on the constraint device. The mounting shaft is rotatably installed in the mounting hole on the adjacent short leg side constraint plate 1 or long leg side constraint plate 4 of the turnout rail, thereby realizing the rotatable installation of the guide wheel 3 on the constraint device on the short leg side constraint plate 1 or long leg side constraint plate 4 of the turnout rail.
[0027] In a preferred embodiment of this utility model, the tilt angle of the guide wheel 3 on the constraint device can be 45° or 43°, which can be adjusted as needed.
[0028] In a preferred embodiment of the present invention, the driving mechanism includes two sets of driving components disposed on both sides of the mounting base 5. The two sets of driving components are respectively connected to the adjacent short leg side constraint plate 1 or long leg side constraint plate 4 of the turnout rail, thereby providing power to the short leg side constraint plate 1 and the long leg side constraint plate 4 of the turnout rail.
[0029] In a preferred embodiment of this utility model, the drive assembly for moving the short leg side constraint plate 1 of the turnout rail includes a threaded rod 7 rotatably mounted on a mounting base 5. The threaded rod 7 has an external thread at one end near the short leg side constraint plate 1, and the external thread engages with a threaded hole on a connecting member 6. The connecting member 6 is fixedly mounted on an adjacent short leg side constraint plate 1. The assembly also includes a power assembly for rotating the threaded rod 7. The power assembly is connected to the threaded rod 7 in a transmission manner. This provides power for the rotation of the threaded rod 7, thereby driving the short leg side constraint plate 1 of the turnout rail to slide.
[0030] The drive assembly for moving the long leg side constraint plate 4 of the turnout rail includes a threaded rod 7 rotatably mounted on a mounting base 5. The threaded rod 7 has an external thread at one end near the long leg side constraint plate 4, and this external thread engages with a threaded hole on a connecting piece 6. The connecting piece 6 is fixedly mounted on an adjacent long leg side constraint plate 4. The assembly also includes a power component for rotating the threaded rod 7. This power component is connected to the threaded rod 7 in a transmission manner. This provides power for the rotation of the threaded rod 7, thereby driving the long leg side constraint plate 4 of the turnout rail to slide.
[0031] In a preferred embodiment of the present invention, the power assembly includes a drive motor 8 fixedly mounted on the mounting base 5, and the drive motor 8 is connected to the threaded rod 7 in a transmission connection, thereby providing power for the rotation of the threaded rod 7.
[0032] In a preferred embodiment of the present invention, the drive assembly may further include a cylinder fixedly mounted on the mounting base 5, the extended end of the cylinder being connected to the adjacent short leg side constraint plate 1 or long leg side constraint plate 4 of the turnout rail.
[0033] In a preferred embodiment of this utility model, the bottoms of the turnout rail short leg side restraint plate 1 and the turnout rail long leg side restraint plate 4 are respectively slidably disposed in the T-shaped grooves on the mounting base 5 via T-shaped pieces. This allows the turnout rail short leg side restraint plate 1 and the turnout rail long leg side restraint plate 4 to be slidably mounted on the mounting base 5.
[0034] The working principle of this utility model is as follows:
[0035] By setting guide wheels 3 on both sides of the walking channel formed between the short leg side constraint plate 1 and the long leg side constraint plate 4 of the turnout rail, the turnout rail 2 is easily guided, so that the turnout rail 2 can pass smoothly and reduce the phenomenon of the turnout rail 2 getting stuck during movement, ensuring that the heat treatment process can be carried out smoothly. If a fault occurs and the turnout rail 2 gets stuck, the drive motor 8 drives the threaded rod 7 to rotate. Under the action of the threaded part on the threaded rod 7, the short leg side constraint plate 1 and the long leg side constraint plate 4 of the turnout rail on both sides move away from each other, so that the stuck turnout rail 2 can be removed quickly.
