Description

Technical Field

[0001] This utility model relates to the field of overhead contact line de-icing technology, and in particular to a railway power supply overhead contact line de-icing vehicle. Background Technology

[0002] The overhead contact line is a special type of power transmission line that is erected above the railway line to supply power to electric locomotives. It is an important part of ensuring the normal operation of trains. Affected by the seasons, especially in winter and early spring, the weather is cold and snowfall and freezing rain are frequent. Special weather conditions can cause ice to accumulate on the overhead contact line. Ice accumulation not only increases the load on the contact line, but in severe cases, it can lead to contact line breakage and cause great economic losses. Ice accumulation also reduces the conductivity of the contact line, affecting the safe operation of trains. Therefore, it is necessary to remove the ice from the contact line. The current de-icing methods are mainly hot sliding de-icing, DC heating wire de-icing, and mechanical de-icing. Mechanical de-icing involves manually knocking on the contact line, which is not ideal and requires a lot of labor intensity for workers. Hot sliding de-icing and DC heating wire de-icing require a lot of energy, which increases costs.

[0003] Therefore, it is necessary to propose an improvement to the railway power supply contact network de-icing vehicle to overcome the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art and provide a de-icing vehicle for railway power supply contact networks.

[0005] The technical solution of this utility model is: A railway power supply contact network de-icing vehicle includes a tractor, a hydraulic station, a scissor lift, and a de-icing mechanism. The hydraulic station and the scissor lift are both mounted on the tractor, and the de-icing mechanism is mounted on the scissor lift. The scissor lift is connected to the hydraulic station. The de-icing mechanism includes a hydraulic motor and a rotating cage. Both the hydraulic motor and the rotating cage are mounted on a base plate. The hydraulic motor is connected to the hydraulic station, and the rotating cage is driven by the hydraulic motor to rotate relative to the base plate.

[0006] Using the above structure, the tractor drives the hydraulic station, scissor lift, and de-icing mechanism to travel along the track. During the journey, the hydraulic station controls the scissor lift to lift the de-icing mechanism, so that the rotating cage contacts the contact wire. The hydraulic station provides power to the drive motor, which drives the rotating cage to rotate. The rotation of the rotating cage and the contact wire generate vibration to remove ice. The de-icing efficiency is high, and the lifting mechanism can meet the de-icing needs of contact wires at different heights, making it highly versatile.

[0007] Preferably, the rotating cage includes a drive shaft and two connecting discs. The two connecting discs are arranged opposite each other on the drive shaft. A number of nylon rods are arranged between the two connecting discs in a circumferential array. The nylon rods are detachably connected to the connecting discs. The nylon rods in the circumferential array remove ice from the contact wire by the amplitude generated when they rotate and come into contact with the contact wire.

[0008] Preferably, the connecting plate has multiple stepped holes arranged in a circumferential array. A pin, a spring, and a hexagonal plug are installed in each stepped hole. The pin is inserted into and slidably disposed in the stepped hole. The hexagonal plug is threaded onto the stepped hole. The spring is disposed between the pin and the hexagonal plug. The end of the nylon rod is provided with a pin hole that matches the pin. The sliding of the pin relative to the stepped hole enables the nylon rod to be installed and removed from the connecting plate, making installation and removal convenient and quick.

[0009] Preferably, the sides opposite the connecting plate are provided with arc-shaped brackets arranged in a circumferential array to support both ends of the nylon rod, thereby enhancing the stability of the nylon rod installation.

[0010] Preferably, the arc-shaped bracket is provided with a first connecting hole, and the nylon rod is provided with a through second connecting hole on its circumference, thereby enhancing the reliability of the nylon rod connection by using the matching first and second connecting holes.

[0011] Preferably, the base plate is provided with two opposing first lifting seats, each with a bearing seat. The two ends of the drive shaft are rotatably connected to the bearing seats. The connection between the drive shaft and the bearing seats supports the drive shaft, thereby improving the sensitivity and stability of the drive shaft rotation.

[0012] Preferably, a second lifting seat is provided on the base plate, and a mounting bracket is provided on the second lifting seat. The hydraulic motor is mounted on the mounting bracket, and one end of the drive shaft passes through the bearing seat and is connected to the hydraulic motor through a coupling. The coupling realizes the transmission connection between the hydraulic motor and the drive shaft, and the transmission is smooth and reliable.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a hydraulic motor to drive the drive shaft and connecting disc to rotate, thereby causing the nylon rods arranged in a circular array between the two connecting discs to rotate synchronously. Through the sequential contact between the nylon plates and the contact wire, vibration is generated between them. The amplitude of the vibration causes the ice on the contact wire to fall off, which protects the contact wire and improves the de-icing efficiency. The tractor travels along the track to achieve continuous de-icing operation on the contact wire. The hydraulic station controls the scissor lift to achieve real-time height adjustment to meet the de-icing requirements of contact wires at different heights. Attached Figure Description

[0016] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0017] Example 1 like Figures 1-5 As shown, a railway power supply contact network de-icing vehicle includes a tractor 1, a hydraulic station 2, a scissor lift 3, and a de-icing mechanism. The tractor 1 can travel along the track and can also be removed from the track without occupying it and affecting its normal operation. The hydraulic station 2 and the scissor lift 3 are both mounted on the tractor 1. The scissor lift 3 is connected to the hydraulic station 2, which provides power to the scissor lift 3 to raise and lower it. The de-icing mechanism is installed at the top of the scissor lift 3 and adjusts its height as the scissor lift 3 rises and falls to adapt to different elevations. The undulating contact wire de-icing mechanism includes a base plate 5, a hydraulic motor 4, and a rotating cage. The base plate 5 is installed on the top of the scissor lift 3. The hydraulic motor 4 and the rotating cage are both installed on the base plate 5, forming a modular whole, which facilitates transportation, installation, and adjustment. The hydraulic motor 4 is connected to the hydraulic station 2, and the hydraulic tensioner provides power to the hydraulic motor 4. The rotating cage and the hydraulic motor 4 are connected by a transmission. The hydraulic motor 4 drives the rotating cage to rotate relative to the base plate 5. The rotating cage comes into contact with the contact wire as the scissor lift 3 rises and falls. The vibration generated by the rotation of the rotating cage achieves de-icing of the contact wire.

[0018] Using the above structure, the tractor 1 drives the hydraulic station 2, scissor lift 3, and de-icing mechanism to travel along the track. During the travel, the hydraulic station 2 controls the scissor lift 3 to drive the de-icing mechanism to achieve reciprocating movement of lifting and lowering, so that the rotating cage maintains reliable contact with the contact wire. The hydraulic station 2 provides power to the drive motor 4, which drives the rotating cage to rotate. The rotation of the rotating cage generates vibration between itself and the contact wire to remove ice. The de-icing efficiency is high, and the lifting and lowering can meet the de-icing needs of contact wires at different heights, making it highly versatile.

[0019] like Figures 2-5 As shown, the rotating drum includes a drive shaft 6, two connecting discs 7, and several nylon rods 8. The two connecting discs 7 are connected opposite each other to the two sides of the drive shaft 6. The several nylon rods 8 are installed between the two connecting discs 7 in a circumferential array. The nylon rods 8 are detachably connected to the connecting discs 7. Specifically, multiple stepped holes 9 are machined in a circumferential array near the edge of the outer circumferential surface of the connecting discs 7. A pin 10, a spring 11, and a hexagonal plug 12 are installed in the stepped holes 9. The pin 10 is inserted into and slidably installed in the stepped hole 9. The hexagonal plug 12 is threaded onto the stepped hole 9. The spring 11 is located between the pin 10 and the hexagonal plug 12. Under the action of the spring 11, the pin 10 extends from the stepped hole 9 to the outside of the connecting disc 7. The end of the nylon rod 8 is machined with a plug hole 13. The plug pin 10 can be inserted and connected to the plug hole 13 to realize the installation of the nylon rod 8 between the two connecting plates 7. After installation, a certain gap is left between the end of the nylon rod 8 and the connecting plate 7 to facilitate the disassembly of the nylon rod 8. During disassembly, the nylon rod 8 can be pushed so that one end of the nylon rod 8 pushes the plug pin 10 at that end to overcome the force of the spring 11 and retract into the connecting plate 7, so that the plug pin 10 at the other end is disconnected from the plug hole 13. The nylon rod 8 can be installed and disassembled on the connecting plate 7 by sliding the plug pin 10 relative to the stepped hole 9. The installation and disassembly are convenient and quick. When the circumferential array of nylon rods 8 rotates, it will generate a vibration effect when it comes into contact with the contact wire in sequence. The vibration amplitude will cause the ice on the contact wire to be vibrated and fall off.

[0020] like Figure 2As shown, a first lifting seat 17 and a second lifting seat 18 are installed on the base plate 5. There are two first lifting seats 17, which are installed opposite each other. Bearing seats 19 are connected to the first lifting seats 17. The two ends of the drive shaft 6 are respectively connected to the two bearing seats 19. The second lifting seat 18 is located on one side of one of the first lifting seats 17. A mounting bracket 20 is installed on the second lifting seat 18. The hydraulic motor 4 is connected to the mounting bracket 20, so that the hydraulic motor 4 and the drive shaft 6 are coaxial. One end of the drive shaft 6 passes through the bearing seat 19 and is connected to the hydraulic motor 4 through a coupling 21. The coupling 21 realizes the transmission connection between the hydraulic motor 4 and the drive shaft 6, ensuring smooth and reliable transmission. By using the installation of the drive shaft 6 in the bearing seat 19, the drive shaft 6 is supported and the sensitivity and stability of the drive shaft 6 rotation are improved.

[0021] Example 2 like Figure 4 and Figure 5 As shown, the two connecting discs 7 have circumferentially arranged arc-shaped brackets 14 machined on their opposite sides. The arc-shaped brackets 14 are adapted to the outer dimensions of the nylon rod 8. The arc-shaped brackets 14 support both ends of the nylon rod 8, enhancing the stability of the nylon rod 8 installation. The nylon rod 8 and the arc-shaped brackets 14 can be fixedly connected or not fixedly connected. When not fixed, after the nylon rod 8 is connected by the insertion pin 10 and the insertion hole 13, the arc-shaped bracket 14 only supports the nylon rod 8. When fixed connection is made, a first connecting hole 15 is machined on the arc-shaped bracket 14, and a second connecting hole 16 is made on the circumference near the end of the nylon rod 8. The second connecting hole 16 passes through the nylon rod 8. After the nylon rod 8 is placed on the arc-shaped bracket 14, the first connecting hole 15 and the second connecting hole 16 are axially aligned and can be connected and fixed in the first connecting hole 15 and the second connecting hole 16 by means of pins or bolts and nuts to enhance the reliability of the connection of the nylon rod 8.

[0022] The working principle of this utility model is as follows: In operation, the tractor 1 travels on the track, and the hydraulic station 2 provides power to the scissor lift 3, driving the scissor lift 3 to rise, so that one of the nylon rods 8 in the de-icing mechanism's rotating cage contacts the contact wire. The hydraulic tension drives the hydraulic motor 4 to work, and the hydraulic motor 4 drives the drive shaft 6 to rotate through the coupling 21, thereby driving the nylon rods 8 in a circular array to rotate synchronously around the axis of the drive shaft 6. During the rotation, several nylon rods 8 contact the contact wire in sequence, generating vibration between them. The amplitude of the vibration causes the ice on the contact wire to vibrate and fall off, achieving the purpose of de-icing. The de-icing efficiency is high. The tractor 1 can travel along the track, and during the travel, it will vibrate and remove the ice on the contact wire in sequence. In addition, during the travel, the scissor lift 3 is controlled to rise and fall in real time to maintain effective contact between the nylon rods 8 and the contact wire, which not only satisfies the requirement of reliable de-icing of the undulating contact wire, but also avoids damage to the contact wire.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent changes and modifications made in accordance with the scope of the claims of this utility model should fall within the technical scope of this utility model.
