Description

Technical Field

[0001] This utility model relates to the field of overhead contact line de-icing technology, specifically to an intercity train overhead contact line de-icing device. Background Technology

[0002] Railway transportation needs to handle a large volume of passenger and freight traffic. In cold weather, due to low temperatures, ice often forms on the overhead contact lines of trains. This ice buildup can lead to poor contact between the pantograph and the contact line, accelerating pantograph wear and tear. In severe cases, it can affect normal train operations and even cause traffic accidents. Therefore, solving the problem of overhead contact line icing is of great significance to the rail transit industry. Under normal circumstances, manual de-icing is required to remove the ice from the contact lines, which poses significant personal safety hazards and is inefficient. Utility Model Content

The top of the lifting mechanism is equipped with a side-tapping mechanism located behind the guide mechanism and continuously tapping both sides of the contact wire. The top of the lifting mechanism is also equipped with a side-milling mechanism for removing ice from the bottom of the contact wire.

[0005] The guiding mechanism consists of a guide plate, a scraper, a guide rod, a base plate, and a tension bearing. The base plate is detachably installed at the top of the lifting mechanism.

[0006] Preferably, the side-tapping mechanism consists of two side-tapping heads, two side-tapping arms, a transmission cam, a support plate, and a transmission motor. The support plate is detachably mounted on the lifting mechanism, and the two side-tapping arms are rotatably mounted on the top of the support plate. The two side-tapping arms are respectively mounted on the ends of the two side-tapping arms.

[0007] Preferably, the transmission cam is located above the support plate and contacts the end of the two side-knob arms away from the side-knob head, and the transmission motor is located in the middle of the support plate and is connected to the transmission cam.

[0022] 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 protection scope of the present utility model.

[0023] Please see Figures 1-5 This utility model proposes an intercity train contact network de-icing device. The de-icing device mainly consists of a lifting mechanism 2 installed on the top of the track carrier 1, a guide mechanism 3, a side knocking mechanism 4 and a side milling mechanism 5 arranged sequentially from front to back on the top of the lifting mechanism 2, which can effectively achieve all-round and efficient de-icing of the contact network on both the upper and lower sides.

[0024] The guiding mechanism 3 consists of a guide plate 301, a scraper 302, a guide rod 303, a base plate 304, and a tension bearing 305. The base plate 304 is detachably mounted on the top of the lifting mechanism 2. Two guide plates 301 are positioned above the base plate 304 and connected by the tension bearing 305. The scraper 302 is located behind the guide plate 301 and connected to the base plate 304 via the guide rod 303. This guiding mechanism 3 uses two mirror-arranged guide plates 301 to guide the position of the contact wire, effectively ensuring that the contact wire remains within the working range of the de-icing device and improving de-icing efficiency. Furthermore, once the contact wire enters the device, the scraper 302 can effectively remove ice columns from the contact wire. The tension bearing 305 can adjust the distance between the two guide plates 301 according to the size of the ice, increasing the adaptability for removing ice of different sizes from the contact wire during the entire de-icing process.

[0025] like Figure 1 and Figure 4As shown, the side-tapping mechanism 4 consists of two side-tapping heads 401, two side-tapping arms 402, a transmission cam 403, a support plate 404, and a transmission motor 405. The support plate 404 is detachably mounted on the lifting mechanism 2. The two side-tapping arms 402 are rotatably mounted on the top of the support plate 404, and the two side-tapping heads 401 are respectively mounted on the ends of the two side-tapping arms 402. The transmission cam 403 is located above the support plate 404 and contacts the ends of the two side-tapping arms 402 away from the side-tapping heads 401. The transmission motor 405 is located in the middle of the support plate 404 and is connected to the transmission cam 403. When the contact line enters the range of the side-tapping mechanism 4, the transmission motor 405 starts running, driving the transmission cam 403 to start rotating, thereby controlling the side-tapping arms 402 in contact with the transmission cam 403 to swing, thereby driving the two side-tapping heads 401 to reciprocate left and right, ultimately realizing the action of tapping ice on both sides of the contact line. The side-tapping head 401 allows for omnidirectional de-icing of the overhead contact line, significantly reducing labor costs and improving the efficiency of de-icing. Furthermore, the adjustable spacing between the two side-tapping heads 401 facilitates flexible operation of the side-tapping mechanism 4 to address various conditions of the overhead contact line.

[0026] like Figure 1 and Figure 5 As shown, the side milling mechanism 5 consists of guide rollers 501, ice-milling blade assembly 502, tension bearing 503, transmission gear 504, support optical shaft 505, and support plate 506. When the contact wire enters the side milling mechanism 5, it passes through the bottom of the guide rollers 501 and winds around to the top of the ice-milling blade assembly 502 to facilitate de-icing of the bottom of the contact wire. The support plate 506 is detachably mounted on the top of the lifting mechanism 2. The guide rollers 501 are rotatably connected to the extension end of the top of the support plate 506. A U-shaped seat is provided on the rear side of the guide rollers 501, and the U-shaped seat is combined with the support plate 506 through four support optical shafts 505. The ice-milling blade assembly 502 is rotatably mounted on the U-shaped seat. The tension bearing 503 and transmission gear 504 are both sleeved on the outer surface of the end of the ice-milling blade assembly 502. The side milling mechanism 5 utilizes an external motor drive structure connected to the transmission gear 504. When the transmission gear 504 is driven to rotate, it can correspondingly drive the ice milling blade assembly 502 to rotate, thereby de-icing the contact line located at the top of the ice milling blade assembly 502.

[0027] like Figure 1 and Figure 2As shown, the lifting mechanism 2 includes a support base 201 mounted on the rail carrier 1. A support spring 202 is installed on the support base 201. A support rod 203 is rotatably connected to the support base 201. A pull rod 204 is connected to the end of the support rod 203. The structure and function of the support base 201, support spring 202, support rod 203, and pull rod 204 are basically the same as those in the prior art, and will not be described in detail here. The purpose is to achieve the function of self-height adjustment. Two guide rails 205 are connected to the flat platform at the end of the pull rod 204. Sliding blocks 206 are slidably sleeved on both guide rails 205. Connecting strips that connect to the support plate 506, support plate 404, and base plate 304 are installed on the top of the two sliding blocks 206. When the path of the rail carrier 1 deviates slightly from the path of the contact line, since the slider 206 and the guide rail 205 are in a sliding connection state, the slider 206 will move laterally on the guide rail 205 during the actual de-icing process, so that the mechanism above it works in accordance with the path of the contact line.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
