Description

Technical Field

[0001] This utility model relates to the field of track maintenance technology, specifically to a fixing clamp for a rail temperature sensor. Background Technology

[0002] Railway tracks play a crucial role in rail transportation, and their temperature variations significantly impact their performance and safety. For example, tracks may deform due to thermal expansion in hot weather, while stress concentration may occur due to contraction at low temperatures. Therefore, accurate monitoring of track temperature is of paramount importance for railway maintenance and safe operation.

[0003] Existing rail temperature sensors often lack a stable, reliable, and easy-to-install and disassemble fixing device. Traditional fixing methods may cause the sensor to loosen or shift due to rail vibration, environmental factors, etc., thus affecting the accuracy of the measurement. Moreover, they cannot be adjusted according to the condition of the rail surface, which is not conducive to the deployment and maintenance of large-scale railway track temperature monitoring networks. Utility Model Content

[0004] The purpose of this invention is to provide a fixing clamp for a rail temperature sensor, which can monitor the rail temperature in real time and can be adjusted according to the condition of the rail surface to achieve a stable and reliable connection with the rail surface, thereby improving measurement accuracy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This utility model provides a fixing fixture for a rail temperature sensor, including a fixture base, the upper end face of which has a groove; a temperature measuring block with a flat top surface and an inclined bottom surface is installed in the groove, the top surface of the temperature measuring block has a mounting groove, a thermally conductive silicone sleeve is installed in the mounting groove, and a temperature sensor is installed in the thermally conductive silicone sleeve.

[0007] The groove is also provided with an adjustment block whose bottom surface is flat and whose top surface matches the inclined surface. The adjustment block is located below the temperature measuring block. The end of the adjustment block is provided with a threaded hole. The side wall of the clamp seat is provided with a through hole that matches the threaded hole. The bolt passes through the through hole and connects with the threaded hole to drive the adjustment block to move horizontally, so that the temperature measuring block can move up and down vertically.

[0008] As a further improvement to the above technical solution, the groove is a cavity that is narrow at the top and wide at the bottom. The top cavity is adapted to the temperature measuring block, so that the temperature measuring block can move up and down in the vertical direction; the bottom cavity is adapted to the adjustment block, so that the adjustment block can move in the horizontal direction.

[0009] As a further improvement to the above technical solution, the perforation is provided with an internal thread, which is adapted to the external thread of the bolt.

[0010] As a further improvement to the above technical solution, one end of the clamp seat is provided with a first slot, which clamps the bottom surface of the rail; the other end of the clamp seat is located on the bottom surface of the rail, and a connecting rod is provided at the end, which is connected and fixed to the second slot by a nut.

[0011] As a further improvement to the above technical solution, the top surface height of the thermally conductive silicone sleeve is slightly greater than the top surface height of the temperature measuring block.

[0012] As a further improvement to the above technical solution, the fixture seat has a through hole on its side wall, which is located on the opposite side of the perforation to facilitate the connection of the temperature sensor.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] In this invention, the temperature sensor is installed inside the temperature measuring block via a thermally conductive silicone sleeve, and then the temperature measuring block contacts the rail. The thermally conductive silicone sleeve can absorb the vibration when the train passes by, eliminating the impact of vibration on the temperature sensor, thereby improving the service life of the temperature sensor. The temperature measuring block can automatically rise with the adjustment of the bolts, maintaining close contact with the rail; therefore, it is not easy to loosen and can maintain a long-term fixation.

[0015] In this invention, the groove on the clamp seat adopts a cavity structure that is narrow at the top and wide at the bottom, which is adapted to the displacement requirements of the temperature measuring block and the adjusting block respectively. The top restricts the vertical displacement of the temperature measuring block, making its movement trajectory clear and stable, and preventing random shaking or deviation. The bottom ensures that the adjusting block can move in the horizontal direction, making the adjustment process smoother. The overall structure fits more tightly and reasonably, thereby enhancing the stability of the entire fixing device during installation and use. Attached Figure Description

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0023] The present invention will be described in detail below with several embodiments.

[0024] Example 1

[0025] like Figures 1 to 4 As shown, this utility model provides a fixing fixture for a rail temperature sensor, including a fixture base 1, the upper end face of which is provided with a groove 2; a temperature measuring block 3 with a flat top surface and an inclined bottom surface 31 is installed in the groove 2, the top surface of the temperature measuring block 3 is provided with a mounting groove 32, a thermally conductive silicone sleeve 33 is provided in the mounting groove 32, and a temperature sensor 4 is provided in the thermally conductive silicone sleeve 33.

[0026] The groove 2 is also provided with an adjustment block 5 whose bottom surface is flat and whose top surface matches the inclined surface 32. The adjustment block 5 is located below the temperature measuring block 3. The end of the adjustment block 5 is provided with a threaded hole 51. The side wall of the clamp seat 1 is provided with a through hole 11 that matches the threaded hole 51. The bolt 6 passes through the through hole 11 and connects to the threaded hole 51 to drive the adjustment block 5 to move horizontally, so that the temperature measuring block 3 can move up and down vertically.

[0027] Specifically, the adjusting block 5 is wedge-shaped and made of stainless steel.

[0028] Specifically, the groove 2 is a cavity that is narrow at the top and wide at the bottom. The top cavity is adapted to the temperature measuring block 3, so that the temperature measuring block 3 can move up and down in the vertical direction; the bottom cavity is adapted to the adjusting block 5, so that the adjusting block 5 can move in the horizontal direction.

[0029] Specifically, the through hole 11 is provided with an internal thread, which is adapted to the external thread of the bolt 6.

[0030] Specifically, one end of the clamping base 1 is provided with a first slot 101, which clamps the bottom surface of the rail 7; the other end of the clamping base 1 is located on the bottom surface of the rail 7, and a connecting rod 8 is provided at the end, which is connected and fixed to the second slot 102 by a nut 9.

[0031] Specifically, the top surface height of the thermally conductive silicone sleeve 33 is slightly greater than the top surface height of the temperature measuring block 3.

[0032] Specifically, the clamp seat 1 has a through hole 12 on its side wall, which is located on the opposite side of the through hole 11; the through hole 12 is preferably a vertical through hole, which is beneficial for the connection of the temperature sensor's connection line to the outside.

[0033] Specifically, the temperature measuring block 3 is provided with a terminal block at the corresponding position. The terminal block is located inside the through hole 12 and has the dual functions of protecting the connecting wire and limiting the position.

[0034] The working principle of this utility model:

[0035] The temperature sensor is installed inside the temperature measuring block via a thermally conductive silicone sleeve, and then the temperature measuring block contacts the rail. The thermally conductive silicone sleeve can absorb the vibration when the train passes by, eliminating the impact of vibration on the temperature sensor, thereby improving the service life of the temperature sensor. By adjusting the bolt, the adjusting block presses the temperature measuring block up and down in the vertical direction, maintaining a tight contact with the rail, so it is not easy to loosen and can maintain a stable and reliable connection.

[0036] The above are merely preferred embodiments of this utility model. It should be noted that, due to the limitations of written expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principle of this utility model, and can also combine the above technical features in an appropriate manner. These improvements, modifications, changes, or combinations, or the direct application of the concept and technical solution of the utility model to other occasions without modification, should all be considered within the protection scope of this utility model.
