Description

Technical Field

[0001] This utility model belongs to the technical field of railway maintenance equipment, specifically, it relates to a contact wire de-icing device. Background Technology

[0002] Currently, during the colder winter months, railway mainlines often experience snow cover or icing in areas with high humidity or frequent snowfall. The areas typically covered by snow and ice are the railway tracks and overhead contact lines. Snowplows are used to clear snow and ice from the tracks and surrounding areas. When the overhead contact line is iced, the conductors directly impact train operation. Ice buildup can cause poor contact between the pantograph and the conductor, leading to power supply issues for the train's electrical equipment and affecting operational safety. Current methods for de-icing conductors mostly rely on manual labor. Railway maintenance personnel use a hammer to tap the conductors, removing the ice. This method is not only physically demanding and inefficient but also requires operation during off-peak seasons. Therefore, there is an urgent need for a contact wire de-icing device to perform de-icing operations on the wires while the train is in motion, replacing manual labor, improving de-icing efficiency, and ensuring that the wires and pantographs are in full contact without affecting train operation. Utility Model Content

[0003] This utility model provides a contact wire de-icing device for de-icing the wires as the train travels, replacing manual labor, improving de-icing efficiency, and without affecting train operation, ensuring full contact between the wires and the pantograph.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Two torsion springs are respectively fitted onto the outside of the second transverse rod and connected to the corresponding parts of the inclined telescopic arm. First adjusting electric cylinders are hinged to both sides of the second transverse rod, and the lower end of each first adjusting electric cylinder is hinged to the fixed seat.

[0014] Furthermore, the inclined cantilever arm includes two cantilever rods, which extend upwards at an angle. A first rod-shaped crossbeam and a second rod-shaped crossbeam are provided between the two cantilever rods. A fixing rod is connected between the first rod-shaped crossbeam and the second rod-shaped crossbeam. A transition sleeve is constructed at the lower end of each cantilever rod. The transition sleeve is rotatably fitted onto the outside of the second transverse rod. One end of the torsion spring is connected to the second transverse rod, and the other end is connected to the transition sleeve.

[0015] Furthermore, the lateral elastic connection assembly includes a first connecting spring, two second connecting springs, and two hinge rods. The first connecting spring is disposed between the two multi-roller de-icing mechanisms, and both ends of the first connecting spring are respectively connected to the two multi-roller de-icing mechanisms. The two hinge rods are arranged laterally along the train. One end of each hinge rod is movably connected to the second rod-shaped crossbeam through a movable sleeve, and the other end of the hinge rod is fixedly connected to the corresponding roller de-icing mechanism through a fixed sleeve. Both second connecting springs are fitted onto the second rod-shaped crossbeam, and a fixed flange is constructed in the middle of the second rod-shaped crossbeam. One end of each second connecting spring is connected to the fixed flange, and the other end of the second connecting spring is connected to the corresponding movable sleeve.

[0016] Furthermore, the multi-roller de-icing mechanism includes a longitudinal roller seat and multiple electrically heated rollers. These electrically heated rollers are rotatably mounted on the longitudinal roller seat at intervals along the length of the train. At both ends of the longitudinal roller seat, there are assembly rods and transverse guide grooves. The assembly rods are connected to the transverse elastic connecting assembly, and the transverse guide rails are slidably connected to the longitudinal roller seat via the transverse guide grooves.

[0017] Furthermore, a downwardly extending guide seat is constructed at the end of the longitudinal roller seat near the train head, and an adapter plate is constructed at the end of the guide seat away from the longitudinal roller seat.

[0020] The technological advancements achieved by this invention compared to existing technologies, due to the aforementioned structure, lie in the following: This invention achieves connection with the train via a fixed base, and by controlling the posture of the adjustable opening and closing frame and / or adjusting the tilt angle adjustment component, the adjustable opening and closing frame drives the multi-roller de-icing mechanism to fully contact the contact wire. During train operation, the laser emitter melts the ice on the wire, causing most of the ice attached to the wire to detach. Next, the multi-roller de-icing mechanism rolls the lower end of the wire, and the multi-roller de-icing mechanism moves along the length of the wire. During the rolling process of the multi-roller de-icing mechanism, the wire undergoes a small vertical and / or lateral displacement, thereby allowing residual ice to quickly detach from the wire. Because the two multi-roller de-icing mechanisms of this invention may move closer or further apart under the action of friction during contact with the wire, the lateral elastic connecting component undergoes corresponding elastic deformation and accumulates energy for the subsequent return of the two multi-roller de-icing mechanisms. In summary, this utility model can perform de-icing operations on the conductor while the train is in motion, effectively replacing manual labor, improving de-icing efficiency, and without affecting train operation, ensuring full contact between the conductor and the pantograph.

Detailed Implementation

[0032] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0033] This utility model discloses a device for de-icing overhead contact wires, such as... Figure 1-8 As shown, the system includes a fixed base 100, an adjustable opening and closing frame 200, a transverse elastic connecting assembly 500, a transverse guide rail 600, an angle adjustment component, and two multi-roller de-icing mechanisms 300. The fixed base 100 is detachably mounted on the roof of the train. The lower end of the adjustable opening and closing frame 200 is connected to the fixed base 100. The two multi-roller de-icing mechanisms 300 are connected transversely and spaced along the upper end of the adjustable opening and closing frame 200. A laser emitter 400 is installed at the end of each multi-roller de-icing mechanism 300 near the front of the train. The laser emitter 400 is aligned with a guide rail and used for de-icing. The transverse elastic connecting assembly 500 is positioned between the two multi-roller de-icing mechanisms 300 and is connected to them. The transverse guide rail 600 is slidably connected to two multi-roller de-icing mechanisms 300. The two ends of the tilt adjustment component are respectively connected to the adjustable opening and closing frame 200 and the transverse guide rail 600. The working principle and advantages of this utility model are as follows: This utility model achieves connection with the train through the fixed base 100, and by controlling the posture of the adjustable opening and closing frame 200 and / or adjusting the tilt adjustment component, the adjustable opening and closing frame 200 drives the multi-roller de-icing mechanism 300 to fully contact the contact wire. During train travel, the laser emitter 400 melts the ice on the wire, causing most of the ice attached to the wire to detach. Next, the multi-roller de-icing mechanism 300 rolls the lower end of the wire, and the multi-roller de-icing mechanism 300 moves along the length of the wire; during the rolling process of the multi-roller de-icing mechanism 300, the wire undergoes a small vertical and / or lateral displacement, thereby causing the remaining ice to quickly detach from the wire. During the contact process between the two multi-roller de-icing mechanisms 300 and the conductor, friction causes them to move closer or further apart. In this situation, the transverse elastic connecting component 500 undergoes corresponding elastic deformation and accumulates energy for the subsequent return of the two multi-roller de-icing mechanisms 300 to their original position. In summary, this invention can perform de-icing operations on the conductor while the train is in motion, effectively replacing manual labor, improving de-icing efficiency, and without affecting train operation, ensuring full contact between the conductor and the pantograph.

[0034] As a preferred embodiment of this utility model, such as Figure 2 , 3As shown, the fixed base 100 includes a frame-shaped base 101, on both sides of which multiple fixing ears 102 are respectively constructed. Each fixing ear 102 is detachably connected to the top of the train by multiple fastening bolts. The adjustable opening and closing frame 200 of this embodiment includes an adjustable opening and closing arm and an inclined cantilever arm. The two ends of the adjustable opening and closing arm are pivotally connected to the fixed base 100 and the inclined cantilever arm, respectively. Two torsion springs 207 are provided at the connection between the adjustable opening and closing arm and the inclined cantilever arm. The end of the inclined cantilever arm away from the adjustable opening and closing arm is connected to two multi-roller de-icing mechanisms 300. The adjustable tensioning arm of this embodiment includes a first transverse rod 201, a second transverse rod 203, and a connecting rod 202. Bearing seats 103 are rotatably connected to both ends of the first transverse rod 201, and each bearing seat 103 is detachably connected to the frame-shaped base 101. The first transverse rod 201 and the second transverse rod 203 are connected together via the connecting rod 202. The second transverse rod 203 is pivotally connected to the inclined cantilever arm. Two torsion springs 207 are respectively fitted onto the second transverse rod 203, and each torsion spring 207 is connected to a corresponding point on the inclined cantilever arm. First adjusting cylinders 204 are hinged to both sides of the second transverse rod 203, and the lower end of each first adjusting cylinder 204 is hinged to the frame-shaped base 101. The inclined cantilever arm of this embodiment includes two extension rods 205, which are arranged side-by-side and both extend upwards at an angle. A first rod-shaped crossbeam 208 and a second rod-shaped crossbeam 209 are arranged between the two outer tension rods 205, and a fixed rod 210 is connected between the first rod-shaped crossbeam 208 and the second rod-shaped crossbeam 209. A transition sleeve 206 is constructed at the lower end of each outer tension rod 205. The transition sleeve 206 is rotatably fitted outside the second transverse rod 203. One end of the torsion spring 207 is connected to the second transverse rod 203, and the other end of the torsion spring 207 is connected to the transition sleeve 206. The working principle and advantages of this embodiment are as follows: This embodiment controls the synchronous operation of two first adjusting electric cylinders 204, so that the two drive the adjustable tensioning arm to rotate a certain angle around the axis of the first transverse rod 201, so that the adjustable tensioning arm drives the inclined outer tensioning arm to move; then, by adjusting the tilt angle adjustment component, the tilt angle of the two multi-roller de-icing mechanisms 300 is adjusted, thereby achieving the purpose of contact between the multi-roller de-icing mechanism 300 and the wire. Since the conductor is not straight, it droops to a certain extent under the action of gravity. During the process of the multi-roller de-icing mechanism 300 contacting the conductor, the multi-roller de-icing mechanism 300 is subjected to different degrees of pressure, which causes the inclined cantilever arm to swing at a corresponding angle along the axis of the second transverse rod 203. At the same time, the torsion spring 207 stores elastic energy to facilitate subsequent return to its original position.

[0035] As a preferred embodiment of this utility model, such as Figure 3-5As shown, the transverse elastic connection assembly 500 includes a first connecting spring 501, two second connecting springs 505, and two hinge rods 502. The first connecting spring 501 is positioned between the two multi-roller de-icing mechanisms 300, and both ends of the first connecting spring 501 are connected to the two multi-roller de-icing mechanisms 300 respectively. The two hinge rods 502 are spaced laterally along the train. Each hinge rod 502 has a movable sleeve 503 and a fixed sleeve 504 at both ends. The hinge rod 502 is movably connected to the second rod-shaped crossbeam 209 via the movable sleeve 503, and is fixedly connected to the corresponding roller de-icing mechanism via the fixed sleeve 504. In this embodiment, both second connecting springs 505 are fitted onto the second rod-shaped crossbeam 209. A fixed flange 211 is constructed in the middle of the second rod-shaped crossbeam 209. One end of each second connecting spring 505 is connected to the fixed flange 211, and the other end of the second connecting spring 505 is connected to the corresponding movable sleeve 503. In this way, as the two multi-roller de-icing mechanisms 300 move closer or further apart, the two multi-roller de-icing mechanisms 300 drive the two hinge rods 502 to move closer or further apart, thereby causing the first connecting spring 501 and the two second connecting springs 505 to undergo elastic deformation and store energy.

[0036] As a preferred embodiment of this utility model, such as Figure 4-6 As shown, the multi-roller de-icing mechanism 300 includes a longitudinal roller seat 301 and a plurality of electrically heated rollers 311. These electrically heated rollers 311 are rotatably mounted on the longitudinal roller seat 301 at intervals along the length of the train. At both ends of the longitudinal roller seat 301, mounting rods 310 and transverse guide grooves 307 are respectively constructed. The mounting rods 310 are connected to the fixing sleeves 504 of the hinge rods 502 in the transverse elastic connection assembly 500. The transverse guide rail 600 of this embodiment includes a guide rail body 601, with a transition seat 602 constructed in the middle of the guide rail body 601. The tilt adjustment component is a second adjusting electric cylinder 700, one end of which is hinged to the transition seat 602, and the other end of which is hinged to a first rod-shaped crossbeam 208 or a fixing rod 210. The guide rail body 601 is slidably connected to the longitudinal roller seat 301 via the transverse guide grooves 307. In this embodiment, by controlling the action of the second adjusting electric cylinder 700, the second adjusting electric cylinder 700 drives the two multi-roller de-icing mechanisms 300 to rotate at a certain angle along the axis of the second rod-shaped crossbeam 209 through the guide rail body 601, thereby adjusting the tilt posture of the two multi-roller de-icing mechanisms 300.

[0037] As a preferred embodiment of this utility model, such as Figure 6-8As shown, a downwardly extending guide seat 302 is constructed at the end of the longitudinal roller seat 301 near the train head, so that the wire can be smoothly and easily guided through the guide seat 302 to the longitudinal roller seat 301, avoiding hard scratching between the longitudinal roller seat 301 and the wire. In this embodiment, a transition plate 303 is constructed at the end of the guide seat 302 away from the longitudinal roller seat 301. An assembly port 304 is opened on the transition plate 303, and transition ears 305 are respectively constructed on both sides of the assembly port 304. The laser emitter 400 is disposed at the assembly port 304, and the laser emitter 400 is detachably connected to the two transition ears 305. A wire passage 306 is formed at the end of the longitudinal roller seat 301 away from the train head. The upper end of the wire passage 306 is in an open state to facilitate the passage of the wire. In this embodiment, vertical mounting holes 308 are respectively provided on the longitudinal roller seat 301 and on both sides of each electric heating roller 311. Sliding blocks 314 are rotatably connected to the transition shafts 312 at both ends of the axial direction of the electric heating roller 311. Each sliding block 314 is slidably mounted in the corresponding vertical mounting hole 308. Connecting edges 309 are respectively constructed on both sides of the lower end of the longitudinal roller seat 301. A vertical spring 316 is installed at the lower end of each sliding block 314, and the lower end of each vertical spring 316 is connected to the corresponding connecting edge 309. When the electric heating roller 311 contacts the wire and the external force of the pressure changes, the electric heating roller 311 moves along the guide of the vertical mounting hole 308, thereby changing the degree of compression of the vertical spring 316. This ensures that the electric heating roller 311 is in full contact with the wire and continuously heats the wire, causing the residual ice on the wire to loosen and detach quickly. In this embodiment, a conductive slip ring 315 is rotatably connected to the end of one of the adapter shafts 312 of the electric heating roller 311. The conductive slip ring 315 is electrically connected to the electric heating roller 311 and is also connected to the conductive wire 313.

Although the 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.
