Description

Technical Field

[0001] This utility model relates to the field of track maintenance technology, and to a fixing device for a track snow melting system. Background Technology

[0002] In winter, railway tracks and urban rail transit tracks are often covered with snow. The icing of snow not only affects the smoothness and safety of train operation but can also lead to various problems such as track circuit failures. Track snow melting systems have emerged to address this issue, using heating elements and spraying de-icing agents to remove snow from the tracks.

[0003] However, existing methods for fixing snow melting system components to the track have shortcomings. Some fixing structures are complex and cannot be adjusted according to the condition of the rail surface. Installation and disassembly are time-consuming and labor-intensive, hindering efficient maintenance and seasonal adjustments. Others have poor fixing stability and are prone to loosening and displacement under long-term train vibration and severe weather impacts, affecting the normal operation of the snow melting system and potentially causing safety hazards due to component detachment. Therefore, there is an urgent need for a convenient, adjustable, and reliable fixing device for track snow melting systems. Utility Model Content

[0004] The purpose of this utility model is to provide a fixing device for a track snow melting system, which solves the problems of complex structure, inability to adjust in real time, and poor stability of existing snow melting system fixing components, and achieves the effects of convenient installation, real-time adjustment, firm fixing and easy maintenance.

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

[0006] A fixing device for a track snow melting system includes a clamp base with a groove on the upper end face of the clamp base; 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 is provided with a mounting groove, and a thermally conductive silicone sleeve is provided in the mounting groove, with a temperature sensor installed inside 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 to the threaded hole.

[0008] 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.

[0009] An installation plate is provided between the second slot and the nut. One end of the installation plate is detachably connected to the connecting rod, and the other end of the installation plate is provided with a slot. An electric heating strip is provided in the slot, and the electric heating strip is tightly connected to the side of the rail through the slot.

[0010] 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.

[0011] As a further improvement to the above technical solution, the adjusting block is wedge-shaped and made of stainless steel.

[0012] 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.

[0013] As a further improvement to the above technical solution, the mounting plate is in the shape of a "┐".

[0014] As a further improvement to the above technical solution, the mounting plate includes a horizontal part and a vertical part, and the vertical part is fixedly connected to the second slot by bolts.

[0015] 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.

[0016] 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.

[0017] As a further improvement to the above technical solution, the through hole is a vertical through hole, and a terminal is provided at the corresponding position of the temperature measuring block; the terminal can be used to protect the connection wire of the temperature sensor on the one hand, and to limit the position on the other hand.

[0018] The beneficial effects of this utility model are as follows:

[0019] In this invention, the electric heating strip is tightly connected to the side of the rail via a mounting plate slot. One end of the mounting plate is detachably connected to the connecting rod, resulting in a simple structure that facilitates future maintenance. The temperature sensor is installed inside the temperature measuring block via a thermally conductive silicone sleeve, which then contacts the rail. The thermally conductive silicone sleeve absorbs vibrations from passing trains, eliminating the impact of vibrations on the temperature sensor and thus improving its lifespan. The temperature measuring block can automatically rise with bolt adjustment, maintaining close contact with the rail.

[0020] 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

[0031] 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.

[0032] One end of the clamping seat 1 is provided with a first slot 101, which clamps the bottom surface of the rail 7; the other end of the clamping seat 1 is located on the bottom surface of the rail 7, and a connecting rod 8 is provided at the end. The connecting rod 8 is connected and fixed to the second slot 102 by a nut 901.

[0033] An mounting plate 13 is provided between the second slot 102 and the nut 901. One end of the mounting plate 13 is detachably connected to the connecting rod 8, and the other end of the mounting plate 13 is provided with a slot 14.

[0034] 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.

[0035] Specifically, the adjusting block 5 is wedge-shaped and made of stainless steel.

[0036] Specifically, the through hole 11 is provided with an internal thread, which is adapted to the external thread of the bolt 6.
