Description

Technical Field

[0001] This utility model relates to the field of heating devices for railway low-temperature freezing damage, specifically a heating device for railway low-temperature freezing damage. Background Technology

[0002] In the cold regions of northern my country, especially the northeast, the continuous heavy snow in winter covers the external locking devices of turnouts, causing components such as the locking frame and locking rod, locking iron and locking hook, and locking frame and locking hook to freeze together. This prevents the external locking devices from working properly, making the turnouts unable to switch flexibly, putting trains in an unsafe state and causing common accidents such as missed trains and delays. This problem is particularly prominent for high-speed railways.

[0003] In the prior art, such as in publication number CN209277085U, a heating device for a railway turnout snow-melting locking frame is disclosed. It includes an electric heating element, an aluminum alloy heat-conducting pad, an elastic clamp, an elastic pressure plate, an aluminum alloy triangular filler block, a railway turnout, and a locking frame. The locking frame is connected to the railway turnout via bolts and nuts. The locking frame has an extension platform at the lower end of the bolts and nuts, with the elastic clamp clamped on both sides of the extension platform. The elastic clamp simultaneously clamps the elastic pressure plate and the aluminum alloy heat-conducting pad. One end of the elastic pressure plate is fixed inside the bolt and nut connecting the locking frame and the railway turnout, and an L-shaped W-shaped electric heating element is connected through the elastic pressure plate. This railway turnout snow-melting locking frame heating device has high heating efficiency, good safety, and is convenient to use and install.

[0004] Although the aforementioned patent can heat the track using electric heating elements, it relies on installing electric heating elements inside the track, which has significant limitations. Installing electric heating elements on existing tracks is cumbersome and impractical. Furthermore, it cannot quickly disassemble and reassemble the heating structure as needed. Therefore, a railway low-temperature freezing damage heating device is proposed to address these issues. Utility Model Content

[0005] To overcome the shortcomings of existing technologies, the heating operation relies on adding electric heating elements inside the track, which has significant limitations. Adding electric heating elements to existing tracks is cumbersome and impractical. Furthermore, it cannot quickly disassemble and reassemble the heating structure as needed. Therefore, this utility model proposes a railway low-temperature freezing damage heating device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The railway low temperature freezing damage heating device of this utility model includes a connecting block. A heating component is fixedly connected to one end of the connecting block, and a clamping rod is fixedly connected to the other end. An axisymmetric insertion hole is opened at one end of the clamping rod, and a connecting component is clamped through the insertion hole. A mounting plate arranged in a ring array is fixedly connected to the side of the connecting component. A threaded hole is opened on the side of the mounting plate, and a bolt is threaded into the threaded hole.

[0007] The heating assembly includes a heating ring fixedly connected to one end of the connecting block. The heating ring has a cavity inside and an induction coil is fixedly connected inside the cavity. A capacitor electrically connected to the induction coil is fixedly connected to the top surface of the heating ring.

[0008] The connecting assembly includes a mounting block, a groove is formed inside the mounting block and a spring telescopic rod is fixedly connected to the inner side wall of the groove, a slide bracket is slidably connected in the groove, one end of the slide bracket extends to the outer surface of the mounting block and protrudes, and an axisymmetric insertion rod that fits into the insertion hole is fixedly connected to the surface of the slide bracket, the position of the insertion rod corresponding to the spring telescopic rod.

[0009] Preferably, the mounting block is fixed to the bottom surface of the train by a mounting plate and bolts, and the insertion rod is inserted into the insertion hole of the locking rod when the spring telescopic rod rebounds to complete the locking.

[0010] Preferably, the capacitor and the induction coil form a resonant circuit and are driven by an external power supply to electromagnetically heat the track inside the heating ring.

[0011] Preferably, when the slide is pressed by an external force, it causes the insert rod to compress the spring telescopic rod and disengage from the insertion hole; when the spring telescopic rod returns to its original position, it pushes the insert rod into the insertion hole to lock the locking rod.

[0012] Preferably, the cavity of the heating ring is arranged around the track and the track surface is heated by electromagnetic induction.

[0013] Preferably, the ring array distribution of the mounting plates ensures that the connection between the mounting block and the bottom surface of the train is subjected to uniform force.

[0014] The advantages of this utility model are:

[0015] 1. This utility model uses a heating ring to wrap around the track and forms a resonant circuit with an internal induction coil and capacitor to directly heat the track surface by electromagnetic induction. It does not require modification of the internal structure of the track and is especially suitable for the treatment of frost damage to existing tracks. It solves the problem of cumbersome operation of adding electric heating elements in the existing technology. The cavity design of the heating ring can be adapted to different track sizes, and the resonant matching of the capacitor and the induction coil significantly improves the heating efficiency.

[0016] 2. This utility model achieves quick assembly and disassembly through the plug-in cooperation of the locking rod and the connecting component. Specifically, pressing the slide bracket causes the plug rod to disengage from the plug hole of the locking rod to unlock it. The spring telescopic rod automatically resets and pushes the plug rod into the plug hole to complete the locking. Combined with the mounting block, it is fixed to the bottom of the train through the mounting plate of the ring array and bolts, so that the heating device can be flexibly assembled and disassembled with the movement of the train. This solves the problem that the existing technology cannot quickly adapt to the heating needs of different positions. Moreover, the axially symmetrical design of the plug rod and the plug hole ensures the stability of the connection. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Please see Figures 1-4As shown, a railway low-temperature freezing damage heating device includes a connecting block 1. A heating component 2 is fixedly connected to one end of the connecting block 1, and a clamping rod 3 is fixedly connected to the other end. One end of the clamping rod 3 has an axisymmetric insertion hole through which a connecting component 4 is clamped. A mounting plate 5 arranged in a ring array is fixedly connected to the side of the connecting component 4. A threaded hole is opened on the side of the mounting plate 5, and a bolt 6 is threaded into the threaded hole. The heating component 2 includes a heating ring 21 fixedly connected to one end of the connecting block 1. The heating ring 21 has a cavity inside, and an induction coil 22 is fixedly connected inside the cavity. A capacitor 23 electrically connected to the induction coil 22 is fixedly connected to the top surface of the heating ring 21.

[0025] During operation, the cavity of the heating ring 21 surrounds the outside of the track to be heated. The induction coil 22 inside the heating ring 21 and the capacitor 23 fixed on the top surface form a resonant circuit through an external power supply. When the power supply is turned on, the induction coil 22 generates a high-frequency alternating magnetic field, which causes the track surface to heat up rapidly due to the eddy current effect, thereby melting the frozen parts. The cavity size of the heating ring 21 can be adapted to different track cross-sectional areas, and no modification to the internal structure of the track is required, making it ready to use immediately after installation.

[0026] Furthermore, the connecting component 4 includes a mounting block 41, a sliding groove is opened inside the mounting block 41 and a spring telescopic rod 42 is fixedly connected to the inner side wall of the sliding groove, a slide bracket 43 is slidably connected inside the sliding groove, one end of the slide bracket 43 extends to the outer surface of the mounting block 41 and protrudes, and an axisymmetric insertion rod 44 that fits into the insertion hole is fixedly connected to the surface of the slide bracket 43, and the position of the insertion rod 44 corresponds to the spring telescopic rod 42;

[0027] During operation, the mounting block 41 of the connecting component 4 is fixed to the bottom of the train by the mounting plates 5 of the annular array and the bolts 6. During installation, pressing the protruding end of the slide 43 causes the insert rod 44 to compress the spring telescopic rod 42 and disengage from the insertion hole of the locking rod 3. After inserting the locking rod 3 into the mounting block 41, the slide 43 is released, and the spring telescopic rod 42 rebounds to push the insert rod 44 into the insertion hole to complete the locking. During disassembly, the heating component 2 and the connecting component 4 can be quickly separated by reversing the operation. The axisymmetric design of the insert rod 44 and the insertion hole ensures the stability of the connection and is suitable for the need to dynamically adjust the heating position while the train is in motion.

[0028] Furthermore, the mounting block 41 is fixed to the bottom surface of the train by the mounting plate 5 and the bolts 6, and the insertion rod 44 is inserted into the insertion hole of the locking rod 3 when the spring telescopic rod 42 rebounds to complete the locking.

[0029] During operation, the mounting block 41 is fixed to the bottom surface of the train via the ring-shaped array of mounting plates 5 and bolts 6. During installation, the bolts 6 are threaded into the pre-drilled holes on the bottom surface of the train to ensure a tight fit between the mounting block 41 and the bottom surface. The insertion rod 44 is automatically inserted into the insertion hole of the locking rod 3 under the rebound force of the spring telescopic rod 42, realizing the quick snap-fit ​​between the heating component 2 and the connecting component 4. This design, through the ring-shaped distribution of the mounting plates 5, evenly distributes the load borne by the mounting block 41, avoiding local stress concentration that could lead to structural deformation. At the same time, the snap-fit ​​between the insertion rod 44 and the insertion hole can be completed without additional tools, significantly improving the stability and maintenance efficiency of the device in the dynamic operating environment of the train.

[0030] Furthermore, capacitor 23 and induction coil 22 form a resonant circuit and are driven by an external power supply to electromagnetically heat the track inside heating ring 21.

[0031] During operation, capacitor 23 and induction coil 22 inside heating ring 21 are connected by wires to form an LC resonant circuit. When driven by an external high-frequency power supply, induction coil 22 generates a high-frequency alternating magnetic field, causing the track surface to heat up rapidly due to the eddy current effect. The hollow structure of heating ring 21 wraps around the outer wall of the track and directly heats the track surface through electromagnetic induction. There is no need to modify the inside of the track or embed electric heating elements. It is especially suitable for the low-temperature freezing damage treatment of existing tracks. The design of the resonant circuit concentrates energy in the target area, and the heating efficiency is more than 30% higher than that of traditional resistance heating. Furthermore, the integrated installation of capacitor 23 and induction coil 22 reduces line loss and ensures reliable operation of the device in low-temperature environments.

[0032] Working principle: The railway low-temperature freezing damage heating device integrates the heating component 2 and the connecting component 4 through the connecting block 1. During installation, the mounting block 41 is first fixed to the bottom of the train using the mounting plate 5 and bolts 6. Then, the protruding end of the slide 43 is pressed to make it slide in the groove, which drives the insertion rod 44 to compress the spring telescopic rod 42. At this time, the locking rod 3 is inserted into the mounting block 41. After releasing the slide 43, the spring telescopic rod 42 rebounds and pushes the insertion rod 44 into the insertion hole of the locking rod 3 to complete the locking, realizing the quick connection between the heating component 2 and the bottom of the train; when the external power supply supplies power to the heating component 2, the capacitor 2 3 forms an LC resonant circuit with the induction coil 22. The induction coil 22 generates a high-frequency alternating magnetic field, causing the track surface wrapped in the cavity of the heating ring 21 to generate eddy currents due to electromagnetic induction and rapidly heat up, thereby melting the frozen parts of the track. When disassembling, the heating component 2 can be separated by pressing the slide 43 in the opposite direction to disengage the insertion rod 44 from the insertion hole. The ring array distribution of the mounting plate 5 ensures that the mounting block 41 is subjected to uniform force. The cooperation between the spring telescopic rod 42 and the insertion rod 44 ensures the stability of the connection. The external design of the heating ring 21 avoids modification of the internal structure of the track, realizing efficient and convenient low-temperature freezing damage heating.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, or similar improvements made within the theoretical and principle content of the present utility model should be included within the protection scope of the present utility model.
