Description

Technical Field

[0001] This utility model relates to the field of railway turnout protection, and in particular to a railway turnout snow melting heating device. Background Technology

[0002] A railway turnout is a device used in railway lines to change the direction of train travel. It uses movable track components to allow a train to switch from one track to another. The main components of a turnout include the turnout point rail, guide rails, and frogs. By adjusting the opening angle of the turnout, trains can smoothly pass through lines in different directions. Railway turnouts play a vital role in railway transportation, especially at stations, intersections, and busy areas. The design and maintenance of turnouts directly affect the safety and efficiency of railway transportation.

[0003] The railway turnout snow melting heating device is a device used in winter to prevent turnouts from icing and accumulating snow, ensuring that trains can pass safely and smoothly. The device provides heat to key parts of the turnout through electric heating or hot water circulation, preventing ice and snow from covering the turnout and avoiding turnout jamming or inability to switch normally due to icing. The snow melting heating device is combined with an automatic monitoring system, which can automatically adjust the heating intensity according to the ambient temperature and humidity. It is especially important in cold regions, improving the safety and reliability of railway transportation.

[0004] One method of electric heating involves using snow-melting heating strips. These strips are fixed to the side wall of the rail on the turnout, transferring heat to the rail and melting the ice and snow covering the turnout, thus preventing it from affecting the turnout's operation. However, traditional snow-melting heating strips are fixed to the rail with bolts and nuts, requiring auxiliary tools for disassembly and replacement, which is time-consuming and laborious. Furthermore, installation holes need to be drilled in the rail, affecting its strength. Therefore, a railway turnout snow-melting heating device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a railway turnout snow melting heating device, which aims to improve the problem that traditional snow melting heating strips are fixed to the rail with bolts and nuts, requiring auxiliary tools for disassembly and replacement, which is time-consuming and laborious, and also requires drilling installation holes in the rail, affecting the strength of the rail.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a railway turnout snow melting heating device, including a track, a snow melting heating strip provided on the outside of the track, a wire fixedly connected to the outside of the snow melting heating strip, a fixing component installed on the outside of the track, and a pressing component installed on the top of the fixing component;

[0007] The fixing assembly includes multiple hook plates, the inner side of which is slidably connected to the bottom of the track. Two sliding shells are fixedly connected to the front side of the hook plates. A push rod is slidably connected inside the sliding shell. A slide plate is fixedly connected to the rear end of the push rod. A spring is fixedly connected to the rear side of the slide plate. A connecting block is fixedly connected to the rear side of the push rod. Four connecting rods are rotatably connected to the outside of the connecting block. A stop block is rotatably connected to the outside of the connecting rods. A mounting plate is slidably connected between the two sliding shells.

[0008] As a further description of the above technical solution:

[0009] The pressure-resistant assembly includes a housing, the bottom of which is fixedly connected to the top of the mounting plate. Two springs are fixedly connected to the inner wall of the housing. A baffle is fixedly connected between the rear ends of the two springs, and a pressure plate is fixedly connected to the rear side of the baffle.

[0010] As a further description of the above technical solution:

[0011] The push rod is fixedly connected to a handle at its front end, and the slide plate is slidably connected to the inner wall of the slide shell.

[0012] As a further description of the above technical solution:

[0013] The rear side of the connecting block is fixedly connected to the front side of the slide plate, and the outer side of the stop block is slidably connected to the inside of the sliding shell.

[0014] As a further description of the above technical solution:

[0015] The rear side of the stop block is slidably connected to the front side of the mounting plate, and one rear end of the spring is fixedly connected to the inner wall of the sliding shell.

[0016] As a further description of the above technical solution:

[0017] The rear side of the mounting plate abuts against the front side of the track, and the rear side of the mounting plate abuts against the front side of the hook plate.

[0018] As a further description of the above technical solution:

[0019] The baffle is externally slidably connected to the inner wall of the housing, and the pressure plate is externally slidably connected to the inside of the housing.

[0020] As a further description of the above technical solution:

[0021] The rear side of the pressure plate is fixedly connected to the front side of the snow melting heating strip.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by hooking the hook plate onto the rear side of the track and pressing the push rod, the sliding plate is driven to compress the spring. At the same time, the connecting block begins to pull the connecting rod to drive the stop block to retract into the sliding shell. At this time, the mounting plate is slid into the outside of the sliding shell and the push rod is released, so that the stop block pops out and blocks the mounting plate. This achieves the ability to quickly fix the snow melting heating strip on the track, saving time and effort.

[0024] 2. In this utility model, the spring pushes the baffle, which in turn drives the pressure plate to squeeze the snow melting heating strip, making the snow melting heating strip tightly adhere to the outside of the track. This ensures that the snow melting heating strip is fully attached to the outside of the track, thereby increasing the heat transfer conversion rate to the inside of the track and avoiding heat waste.

[0033] The fixing assembly includes multiple hook plates 4. The inner side of the hook plates 4 is slidably connected to the bottom of the track 1. Two sliding shells 5 are fixedly connected to the front side of the hook plates 4. A push rod 6 is slidably connected inside the sliding shell 5. A slide plate 7 is fixedly connected to the rear end of the push rod 6. A spring 8 is fixedly connected to the rear side of the slide plate 7. A connecting block 9 is fixedly connected to the rear side of the push rod 6. Four connecting rods 10 are rotatably connected to the outside of the connecting block 9. A stop block 11 is rotatably connected to the outside of the connecting rods 10. A mounting plate 12 is slidably connected between the two sliding shells 5. The hook plates 4 are used to pass under the track 1 and hook onto the other side of the track 1. The sliding shells 5 are used to connect and protect the internal parts. The push rod 6 is used to drive the slide plate 7 to compress the spring 8 and drive the connecting block 9 to move. The slide plate 7 is used to compress the spring 8 and bear the thrust from the spring 8. The spring 8 is used to drive the slide plate 7 to reset and extend the stop block 11. The connecting block 9 is used to drive the connecting rods 10 to deflect and move the stop block 11. 11 is to block the mounting plate 12, so that the mounting plate 12 is fixed on the track 1. The mounting plate 12 is used to support the pressure component and cooperate with the hook plate 4 to fix the snow melting heating strip 2 to the outside of the track 1. The front end of the push rod 6 is fixedly connected to the handle 17, which is used to facilitate manual pressing of the push rod 6. The outer side of the slide plate 7 is slidably connected to the inner wall of the slide shell 5 to limit the movement direction of the slide plate 7. The rear side of the connecting block 9 is fixedly connected to the front side of the slide plate 7 so that the connecting block 9 and the slide plate 7 move synchronously. The outer side of the stop block 11 is slidably connected to the inside of the slide shell 5 to limit the movement direction of the stop block 11. The rear side of the stop block 11 is slidably connected to the front side of the mounting plate 12 so that the mounting plate 12 is installed on the front side of the hook plate 4. The rear end of the spring 8 is fixedly connected to the inner wall of the slide shell 5 so that the spring 8 is kept stable. The rear side of the mounting plate 12 abuts against the front side of the track 1, and the rear side of the mounting plate 12 abuts against the front side of the hook plate 4 so that the mounting plate 12 is kept stable.

[0034] Reference Figures 1-4The pressure assembly includes a housing 13, the bottom of which is fixedly connected to the top of the mounting plate 12. Two springs 14 are fixedly connected to the inner wall of the housing 13. A baffle 15 is fixedly connected between the rear ends of the two springs 14. A pressure plate 16 is fixedly connected to the rear side of the baffle 15. The housing 13 is used to connect and protect the internal parts. The springs 14 are used to push the baffle 15 to move. The baffle 15 is used to move the pressure plate 16 synchronously. The pressure plate 16 is used to press the snow melting heating strip 2 against the outside of the snow melting heating strip 2. The baffle 15 is slidably connected to the inner wall of the housing 13, and the pressure plate 16 is slidably connected to the inside of the housing 13. The housing 13 simultaneously restricts the movement direction of the baffle 15 and the pressure plate 16. The rear side of the pressure plate 16 is fixedly connected to the front side of the snow melting heating strip 2, so that the heat is fully transferred to the track 1.

[0035] Working principle: When using the snow melting heating strip 2, first install the snow melting heating strip 2 on the track 1. Pass the hook plate 4 through the bottom of the track 1, then align the mounting plate 12 with the hook plate 4 on the hook plate 4, and press the handle 17 through the mounting hole of the mounting plate 12. This will drive the push rod 6 to move, causing the slide plate 7 to compress the spring 8. This will cause the connecting block 9 to drive the connecting rod 10 to pull the stop block 11, retracting the stop block 11 into the slide shell 5. Then, push the mounting plate 12 forcefully until it is fully in contact with the track 1. At the same time, the snow melting heating strip 2 will stick to the track 1, causing the pressure plate 16 to press the stop plate 15 and compress the spring 14. At this time, release the handle 17, and the slide plate will begin to move under the action of the spring 8. 7. The push rod 6 is reset, causing the connecting block 9 to drive the connecting rod 10 to push out and unfold the stop block 11, blocking it outside the mounting plate 12, thereby achieving installation and fixation, saving time and effort, and effectively improving installation efficiency. In conjunction with the spring 2 14, the baffle 15 is pushed to drive the pressure plate 16 to squeeze the snow melting heating strip 2, firmly pressing the snow melting heating strip 2 against the outside of the track 1, avoiding gaps between the snow melting heating strip 2 and the track 1 that would cause heat loss and waste. At this time, the controller transmits electricity along the wire 3 to the snow melting heating strip 2, heating the snow melting heating strip 2, and effectively transferring heat to the track 1, allowing the heat to quickly melt the ice and snow on the track 1, effectively ensuring the safety of train operation.
