Description

Technical Field

[0001] The present invention relates to the field of railway electrical technology, and particularly to an ice remover for high-speed railway catenaries. Background Art

[0002] The high-speed railway catenary is a transmission line erected above the railway line to supply power to electric locomotives. The current relied on by high-speed trains during operation is transmitted through the catenary at the upper end of the locomotive. Therefore, it is an important part of the energy supply during the operation of high-speed railway locomotives. However, the high-speed railway catenary will freeze in winter ice and snow weather. When the contact wire part of the high-speed railway catenary is covered with ice and snow, it will cause the pantograph of the locomotive to be unable to effectively make contact for power supply. Therefore, it is necessary to de-ice the high-speed railway catenary in a timely manner.

[0003] In the prior art, the relatively common de-icing method at home and abroad is the manual removal method. This method is currently commonly used for overhead transmission lines and catenaries in China. It mainly removes ice and snow through simple measures such as manual knocking and / or the impact operation of installing a copper bow head on the locomotive. This method is the simplest and the earliest de-icing method. However, it requires a large amount of manpower and material resources, takes a long time, has low de-icing efficiency, poor de-icing effect, often re-freezes after de-icing, and has a certain degree of danger. Moreover, when the icing phenomenon occurs, the environmental conditions are often relatively harsh, making manual de-icing extremely inconvenient.

[0004] Traditional ice removers are generally installed on a single wire for mobile de-icing. However, the high-speed railway catenary is composed of a carrier cable, a catenary, and suspension strings. The carrier cable and the catenary form a double-layer line structure. Therefore, when traditional ice removers are used for de-icing the high-speed railway catenary, there are the following problems. Firstly, the suspension strings separate the lines, resulting in multiple spaces between the carrier cable and the catenary, making it impossible to use for long-distance de-icing. Secondly, the joints of the suspension strings are uneven, which may cause jamming during movement. In addition, the gaps between the carrier cable and the catenary are not the same, making it impossible to move stably. Finally, for high-speed railway catenary de-icing, only the contact surface of the contact wire needs to be de-iced, and the overall de-icing of traditional ice removers also reduces the de-icing efficiency. Therefore, the present invention needs to solve the problem of de-icing for use on high-speed railway catenaries. Summary of the Invention

[0005] Aiming at the deficiencies of the above-mentioned prior art, the present invention provides an ice remover for high-speed railway catenaries, which can be firmly installed on the high-speed railway catenary for use, move smoothly, and can break and remove the ice covering on the catenary efficiently and with high precision.

[0006] Technical solution provided by the present invention: An ice remover for high-speed rail catenary, comprising two sets of driving wheel mechanisms for being installed above the catenary. The two sides of the two sets of driving wheel mechanisms are respectively connected into one body through fixing plates. At both ends of the bottom of each set of driving wheel mechanisms, connecting seats are respectively arranged. At the lower end of each connecting seat, a tensioning mechanism is provided. The lower end of the tensioning mechanism is connected to two driven wheel covers. Between the two driven wheel covers, a driven rotating wheel is movably installed. At the front end of the driven wheel cover, an extension rod is welded. At the front end of the extension rod, an installation cover is fixedly installed. At the front end of the installation cover, an ice scraping knife is fixedly installed. On the outer side of the extension rod, an installation frame is fixedly installed. At the lower end of the installation frame, an installation sleeve is fixedly installed. Inside the installation sleeve, an insertion rod is provided. At the front end of the insertion rod, an ice breaking mechanism is fixedly connected.

[0007] Further, each set of driving wheel mechanisms includes a driving inner wheel. At both ends of the driving inner wheel, outer wheel rims are fixedly installed. At one end of the outer wheel rim, a driving wheel cover is fixedly installed. At one end of the driving wheel cover, a driving docking column is fixedly installed. A positioning ring is sleeved on the outer side of the driving docking column. The fixing plate is arranged between the positioning rings of the two sets of driving wheel mechanisms. At one end of the driving docking column, a fixed outer cover is movably installed. On one side of the fixed outer cover, a driving motor is fixedly installed.

[0008] Further, the outer wheel rim is designed in a conical shape. The outer wheel rim, the driving wheel cover, the driving docking column, the positioning ring, and the fixed outer cover are divided into two groups and symmetrically arranged and installed around the driving inner wheel.

[0009] Further, the driving motor is connected to the fixed outer cover on one side. The output shaft of the driving motor passes through the fixed outer cover and is connected to the driving docking column. The driving docking columns on both sides rotate and move around the middle of the two fixed outer covers. The positioning ring rotates and moves around the driving docking column.

[0010] Further, the tensioning mechanism includes a first connecting rotating shaft, a second connecting rotating shaft, a connecting column, a telescopic rod, and a tensioning spring. At the upper end of each driven wheel cover, two first connecting rotating shafts are respectively installed. At the lower end of each connecting seat, a second connecting rotating shaft is respectively installed. The connecting column and the telescopic rod are movably installed between the first connecting rotating shaft and the second connecting rotating shaft. The connecting column is located below the telescopic rod. The tensioning spring is installed on the outer side of the telescopic rod.

[0011] Further, the telescopic rod is inserted into the connecting column and telescopically moves with it. The lower end of the tensioning spring is fixedly connected to the upper end of the connecting column.

[0012] Further, a locking screw is provided at the rear end of the installation sleeve. The rear section of the insertion rod is inserted into the installation sleeve. The locking screw penetrates into the interior of the installation sleeve and is threadedly connected to the insertion rod.

[0013] Further, the ice-breaking mechanism includes a motor plate, an ice-breaking motor, a rotating shaft, connecting rubber blocks, and a striking plate. The motor plate is fixedly installed at the front end of the insertion rod, the ice-breaking motor is fixedly installed at the rear end of the motor plate, the rotating shaft is movably installed at the front end of the motor plate, a plurality of connecting rubber blocks are fixedly installed on the outer side of the rotating shaft, and the striking plate is installed on the outer side of the connecting rubber blocks.

[0014] Further, the rotating shaft penetrates through the motor plate and is connected to the ice-breaking motor. The ice-breaking motor is located in the middle of the two insertion rods, and a plurality of connecting rubber blocks and the striking plate are evenly installed around the center of the rotating shaft.

[0015] Further, anti-slip convex teeth are integrally formed on the outer side of the outer wheel rim.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] By driving the inner wheel and the driven runner to form a double-layer structure, the driving inner wheel is installed above the carrier cable of the catenary, and the driven runner is installed below the contact wire of the catenary. Then, the upper and lower docking is realized by the connecting column and the telescopic rod, so that the driving inner wheel and the driven runner avoid the dropper between the carrier cable and the contact wire during movement. Therefore, longer-distance moving de-icing is more suitable for de-icing of high-speed rail catenaries;

[0018] By installing the outer wheel rim on the outer side of the driving inner wheel, when the driving inner wheel fits the carrier cable, the outer wheel rim increases the inner diameter of the overall part of the driving wheel. Therefore, when the driving inner wheel moves to the dropper connection on the carrier cable, the outer wheel rim contacts the dropper connection and rotates, and the anti-slip convex teeth prevent slipping, so that the driving wheel part quickly turns over the dropper connection, preventing jamming caused by movement on the carrier cable. Moreover, the large inner diameter anti-slip structure of the outer wheel rim and the anti-slip convex teeth is more suitable for movement on the ice surface;

[0019] Through the connection of the positioning ring and the fixing plate to the two driving inner wheels, when one driving inner wheel and the outer wheel rim cross the dropper connection, the up-and-down movement is eliminated through the movable connection between the positioning ring and the driving docking column, which will not affect the movement of the other driving inner wheel and the outer wheel rim, making the movement of the driving wheel part stable, and more suitable for movement on the uneven ice surface and high-speed rail catenaries;

[0020] Through the connection of the tensioning mechanism, the tensioning spring drives the connecting column and the telescopic rod to tighten and contract, so that the driving inner wheel and the driven runner are kept in tension. Therefore, when the distance between the carrier cable and the contact wire is different, by keeping the driving inner wheel and the driven runner in tension, the falling off during movement is prevented, making the de-icing machine firmly installed on the high-speed rail catenary for use;

[0021] By quickly disassembling and assembling the ice-breaking mechanism, the insertion rod is inserted into the installation sleeve and firmly connected by locking screws. Therefore, after the locking screws are removed, the insertion rod can also be quickly removed from the installation sleeve, thus realizing the quick disassembly and assembly of the ice-breaking mechanism. When the catenary is frozen too thickly, the ice-breaking mechanism is installed and used. When the ice is relatively thin, the ice-breaking mechanism is removed, and the ice can be removed only by the movement of the ice-scraping knife, which is more convenient for the ice-removing machine to remove ice under different conditions and enables the ice-removing machine to perform ice-removing operations more efficiently.

[0031] As Figures 1-5 shown, the de-icing machine for high-speed rail catenary includes two groups of driving wheel mechanisms for installation above the catenary 30. The two sides of the two groups of driving wheel mechanisms are connected into one body through fixing plates 7 respectively. At both ends of the bottom of each group of driving wheel mechanisms, connection seats 10 are respectively arranged. At the lower end of each connection seat 10, a tensioning mechanism is provided. The lower end of the tensioning mechanism is connected with two driven wheel covers 16. Between the two driven wheel covers 16, a driven runner 24 is movably installed. At the front end of the driven wheel cover 16, an extension rod 17 is welded. At the front end of the extension rod 17, an installation cover 18 is fixedly installed. At the front end of the installation cover 18, an ice scraping knife 19 is fixedly installed. On the outer side of the extension rod 17, an installation frame 20 is fixedly installed. At the lower end of the installation frame 20, an installation sleeve 21 is fixedly installed. Inside the installation sleeve 21, an insertion rod 22 is provided. At the front end of the insertion rod 22, an ice breaking mechanism is fixedly connected.

[0032] As Figure 2 and Figure 3 shown, each group of the driving wheel mechanisms includes a driving inner wheel 1. At both ends of the driving inner wheel 1, outer wheel rims 2 are fixedly installed. On the outer side of the outer wheel rim 2, anti-slip convex teeth 3 are integrally formed. At one end of the outer wheel rim 2, a driving wheel cover 4 is fixedly installed. At one end of the driving wheel cover 4, a driving docking column 5 is fixedly installed. A positioning ring 6 is sleeved on the outer side of the driving docking column 5. The fixing plate 7 is arranged between the positioning rings 6 of the two groups of driving wheel mechanisms. At one end of the driving docking column 5, a fixed outer cover 8 is movably installed. On one side of the fixed outer cover 8, a driving motor 9 is fixedly installed.

[0033] In this embodiment, the outer rim 2 is designed in a conical shape. The outer rim 2, the drive wheel cover 4, the drive docking column 5, the positioning ring 6, and the fixed outer cover 8 are arranged symmetrically around the drive inner wheel 1 in two groups. Two outer rims 2, drive wheel covers 4, drive docking columns 5, positioning rings 6, fixed outer covers 8, and one drive inner wheel 1 form a set of drive wheel mechanisms.

[0034] The drive motor 9 is connected to the fixed outer cover 8 on one side. The output shaft of the drive motor 9 passes through the fixed outer cover 8 and is connected to the drive docking column 5. The drive docking columns 5 on both sides rotate around the middle of the two fixed outer covers 8. The drive motor 9 drives the drive docking column 5 to rotate, thereby driving the middle outer rim 2 and the drive inner wheel 1 to rotate. The positioning ring 6 rotates around the drive docking column 5. The positioning ring 6 and the fixing plate 7 play a role in docking the two drive wheel mechanisms.

[0035] As Figure 4 shown, the tensioning mechanism includes a first connecting rotating shaft 11, a second connecting rotating shaft 12, a connecting column 13, a telescopic rod 14, and a tensioning spring 15. Two first connecting rotating shafts 11 are respectively installed at the upper ends of each driven wheel cover 16. Two second connecting rotating shafts 12 are respectively installed at the lower ends of each connecting seat 10. The connecting column 13 and the telescopic rod 14 are movably installed between the first connecting rotating shaft 11 and the second connecting rotating shaft 12. The connecting column 13 is located below the telescopic rod 14. The tensioning spring 15 is installed outside the telescopic rod 14. The telescopic rod 14 is inserted into the connecting column 13 and is telescopically movable therewith. The lower end of the tensioning spring 15 is fixedly connected to the upper end of the connecting column 13. The tensioning spring 15 drives the connecting column 13 and the telescopic rod 14 to remain contracted.

[0036] As Figure 5 shown, a locking screw 23 is provided at the rear end of the mounting sleeve 21. The rear section of the insertion rod 22 is inserted into the mounting sleeve 21. The locking screw 23 penetrates into the interior of the mounting sleeve 21 and is threadedly connected to the insertion rod 22. The insertion rod 22 and the mounting sleeve 21 are firmly connected by the locking screw 23.

[0037] In one embodiment, the ice-breaking mechanism includes a motor plate 25, an ice-breaking motor 26, a rotating shaft 27, connecting rubber blocks 28, and a striking plate 29. The motor plate 25 is fixedly installed at the front end of the insertion rod 22, the ice-breaking motor 26 is fixedly installed at the rear end of the motor plate 25, the rotating shaft 27 is movably installed at the front end of the motor plate 25, a plurality of connecting rubber blocks 28 are fixedly installed on the outer side of the rotating shaft 27, and the striking plate 29 is installed on the outer side of the connecting rubber blocks 28. The rotating shaft 27 penetrates through the motor plate 25 and is connected to the ice-breaking motor 26. The ice-breaking motor 26 is located in the middle of the two insertion rods 22. A plurality of connecting rubber blocks 28 and the striking plate 29 are evenly installed around the center of the rotating shaft 27. The ice-breaking motor 26 drives the rotating shaft 27 to rotate. After the striking plate 29 strikes the contact wire, it uses the elastic deformation of the connecting rubber blocks 28 to cross the contact wire and continue to rotate.

[0038] When the present invention is in use, two driving inner wheels 1 are installed above the load-bearing cable 30 of the catenary, and the driven rotating wheel 24 is installed below the contact wire 32 of the catenary. After the driving motor 9 is powered on and operates, the driving motor 9 drives the driving docking column 5 to rotate inside the two fixed outer covers 8, thereby driving the driving inner wheels 1 to rotate. Through the rotation of the two driving inner wheels 1, the ice-breaking mechanism is moved on the catenary. While moving, the ice-breaking motor 26 is powered on and operates to drive the rotating shaft 27 to rotate. Therefore, the connecting rubber blocks 28 and the striking plate 29 outside the rotating shaft 27 rotate continuously, causing the striking plate 29 to strike the ice on the contact wire, thereby generating vibration to break the ice and make it fall off. At the same time, the ice-scraping knife 19 in front of the installation cover 18 is sleeved under the catenary, so that the residual ice on the catenary is completely removed during movement, realizing the de-icing of the high-speed rail catenary.

[0039] The driving inner wheels 1 and the driven rotating wheel 24 form a double-layer structure. When the de-icing machine is installed on the high-speed rail catenary, the driving inner wheels 1 are installed above the load-bearing cable of the catenary, and the driven rotating wheel 24 is installed below the contact wire of the catenary. Then, the upper and lower docking is realized by the connecting column 13 and the telescopic rod 14, so that the driving inner wheels 1 and the driven rotating wheel 24 avoid the suspension string 31 between the load-bearing cable and the contact wire during movement, and thus can move for a longer distance for de-icing.

[0040] By installing the outer wheel ring 2 on the outer side of the driving inner wheel 1, when the driving inner wheel 1 fits the load-bearing cable, the outer wheel ring 2 increases the inner diameter of the overall part of the driving wheel. Therefore, when the driving inner wheel 1 moves to the connection point of the suspension string on the load-bearing cable, the outer wheel ring 2 contacts the connection point of the suspension string and rotates, and the protrusions of the anti-slip convex teeth 3 prevent slipping, enabling the driving wheel part to quickly turn over the connection point of the suspension string.

[0041] Through the connection of the two driving inner wheels 1 by the positioning ring 6 and the fixing plate 7, two sets of positioning rings 6 are sleeved on the outer side of the driving docking column 5, and then the connection is made by the installation of the fixing plate 7, so that the connection between the two driving inner wheels 1 is realized, and the positioning ring 6 can rotate around the driving docking column 5. Therefore, when one of the driving inner wheels 1 and the outer wheel ring 2 cross the suspension connection point, the up-and-down movement is eliminated through the movable connection between the positioning ring 6 and the driving docking column 5, without affecting the movement of the other driving inner wheel 1 and the outer wheel ring 2, and the part of the driving wheel moves smoothly.

[0042] Through the connection of the tensioning structure, four sets of connecting columns 13 and telescopic rods 14 realize the docking of the two driving inner wheels 1 and the driven rotating wheel 24. The tensioning spring 15 drives the connecting columns 13 and the telescopic rods 14 to tighten and contract, so that the driving inner wheel 1 and the driven rotating wheel 24 are kept in tension. At the same time, the movable connection is realized by the connecting rotating shaft. Therefore, when the distance between the catenary and the contact wire is different, by keeping the driving inner wheel 1 and the driven rotating wheel 24 in tension, the falling off during movement is prevented.

[0043] Through the quick disassembly and assembly of the ice-breaking mechanism, the rear section of the insertion rod 22 is inserted into the installation sleeve 21, and then the insertion rod 22 and the installation sleeve 21 are firmly connected by locking the screw 23. Therefore, after the locking screw 23 is removed, the insertion rod 22 can also be quickly removed from the installation sleeve 21, so as to realize the quick disassembly and assembly of the ice-breaking mechanism. When the contact wire is frozen too thickly, the ice-breaking mechanism is installed for use, and when the ice is relatively thin, the ice-breaking mechanism is removed, and the ice can be removed only by the movement of the ice scraping knife 19.

[0044] The above description is only a detailed description of the specific implementation of the present invention, and does not limit the present invention. Any modifications, equivalent replacements, and improvements made on the design concept of the present invention shall be included in the protection scope of the present invention.
