Description

Technical Field

[0001] This invention relates to the field of monorail vehicle technology, and mainly to a current collector for monorail vehicle bogies. Background Technology

[0002] With the continuous development of urban transportation, monorail vehicles, as a new type of transportation, have gradually gained attention and popularity. Monorail vehicles generally use DC third rail power supply, with the power supply rail installed on the track beam, reducing the impact on the urban landscape.

[0003] Currently, current collectors on general current collectors are installed on stabilizer wheel brackets, and are usually fixed by welding or bolts. Bolts are prone to loosening over long-term use, resulting in unstable installation of the current collector. Secondly, the current collector slipper on the current collector needs a certain elasticity when swinging, which is usually achieved by a spring. However, springs have a certain irregularity and are prone to positional displacement, which causes the position of the current collector slipper to shift. Summary of the Invention

Example

[0026] Please see Figure 1-6 The monorail vehicle bogie current collector in this embodiment includes a track 1, a bogie body 2 above the track 1, and a running wheel 3 mounted on the inner center of the bogie body 2. The running wheel 3 is driven by a drive device 4 to achieve the movement of the monorail vehicle. First mounting brackets 5 are mounted at the four corners of the bottom wall of the bogie body 2, and guide wheels 6 are mounted at the bottom of the first mounting brackets 5. Second mounting brackets 7 are mounted on both sides of the bottom wall of the bogie body 2, located between the two first mounting brackets 5, and stabilizing wheels 8 are mounted at the bottom of the second mounting brackets 7 to maintain track stability. Stability during the turning process of track 1; A current collector 9 is detachably installed on one side of the second mounting frame 7. The current collector 9 is equipped with a swingable current collector 10 inside. The current collector 10 is connected to a current collector slipper 11. A bracket 12 is mounted on one side of the current collector slipper 11. Brackets 12 are installed on both sides of track 1. An insulating component 13 is installed on one side of the bracket 12. A power supply rail 1301 is installed on one side of the insulating component 13. The current collector slipper 11 can be in contact with the power supply rail 1301. Through the adjustment of the swing rod 16, the current collector slipper 11 and the power supply rail 1301 are brought into contact, thereby supplying power to the monorail vehicle.

[0027] For examples, please refer to Figure 6Multiple extension seats 901 are fixedly connected to one side of the current collector 9. Multiple open slots 903 are opened on the side wall of the current collector 9. Electric push rods 904 are installed on the inner side wall of the open slots 903. Push blocks 905 are connected to the end of the actuator rod of the electric push rods 904. Push blocks 905 and open slots 903 are slidably engaged. Push blocks 905 are connected to the side wall of the extension seats 901. A snap-fit ​​groove 902 is opened on one side of the extension seats 901. Extension blocks 701 are fixedly connected to both side walls of the second mounting bracket 7. Extension blocks 701 and snap-fit ​​grooves 902 are inserted into each other.

[0028] It should be noted that the forward extension of the electric push rod 904 pushes the push block 905 to slide inside the open slot 903. The open slot 903 drives the extension seat 901 to move, so that the extension block 701 is engaged with the snap-fit ​​slot 902. At this time, the extension block 701 is fully engaged with the snap-fit ​​slot 902.

[0029] For examples, please refer to Figure 6 The extension base 901 has circular grooves 906 on both the upper and lower parts. A reset block 907 is slidably connected to the inner side of the circular groove 906. A pull column 908 is fixedly connected to the top wall of the reset block 907. A first spring 909 is fixedly wound around the outside of the pull column 908. The extension block 701 has snap-fit ​​blocks 702 on both the top and bottom. The circular groove 906 and the snap-fit ​​block 702 are inserted and engaged.

[0030] It should be noted that the outward pulling of the pulling column 908 causes the reset block 907 to move toward the locking block 702, thus disengaging it from the locking groove 902. As the pulling column 908 moves outward, the first spring 909 is compressed and deformed. After the pulling column 908 is released, the elastic force of the first spring 909 is restored, causing the pulling column 908 to move toward the inside of the circular groove 906. At the same time, the reset block 907 also moves toward the locking block 702 until the reset block 907 and the locking block 702 are fully engaged, thus connecting the current collector 9 to the second mounting bracket 7.

[0031] For examples, please refer to Figure 3 The upper and lower walls of the current collector 9 are fixedly connected with fixing plates 14, and the fixing plates 14 are connected and fixed to the second mounting bracket 7 by fastening bolts 15.

[0032] It should be noted that the fixing plate 14 and the second mounting bracket 7 are locked and fixed by multiple fastening bolts 15 to maintain the firmness of the connection of the current collector 9.

[0033] For examples, please refer to Figure 3 and Figure 4A swing rod 16 is hinged to the inner wall of the second mounting frame 7. A fixed cylinder 17 is connected to the other side wall of the second mounting frame 7. A telescopic column 18 is connected to the telescopic end of the fixed cylinder 17. A second spring 19 is fixedly wound around the outside of the telescopic column 18. The end of the telescopic column 18 is connected to the side wall of the swing rod 16. A connecting seat 20 is hinged to the end of the swing rod 16 away from the inner wall of the stabilizing wheel 8. The current receiver 10 is connected to the side wall of the connecting seat 20.

[0034] It should be noted that while the swing arm 16 is being adjusted, the telescopic column 18 will also extend and retract, causing the second spring 19 to stretch or compress and deform, thereby providing a certain buffering effect to the flow-receiving slipper 11 during adjustment.

[0035] For examples, please refer to Figure 3 One end of the stabilizing wheel 8 is fixedly connected to an L-shaped plate 21. The top of the L-shaped plate 21 is provided with a groove 22. A slider 23 is slidably connected to the inside of the groove 22. The upper end of the slider 23 is connected to the bottom end of the connecting seat 20.

[0036] It should be noted that when the swing arm 16 is adjusted, its end can maintain good stability because the slider 23 slides inside the groove 22.

[0037] For examples, please refer to Figure 4 A support plate 24 is fixedly connected to the side of the stabilizing wheel 8 near the swing rod 16. The support plate 24 is connected to the side wall of the swing rod 16 through a third spring 25.

[0038] It should be noted that the third spring 25 will also stretch and compress as the swing arm 16 is adjusted, working together with the second spring 19 and the telescopic column 18 to provide a double buffer protection effect.

[0039] In summary, the invention, through the cooperation between the fixing plate 14 and the fastening bolt 15, can connect and fix the second mounting bracket 7 and the current collector 9. Simultaneously, the cooperation of the extension block 701, snap-fit ​​block 702, extension seat 901, snap-fit ​​groove 902, open groove 903, electric push rod 904, push block 905, circular groove 906, reset block 907, pulling column 908, and first spring 909 further strengthens the connection between the second mounting bracket 7 and the current collector 9. These two connection methods improve the stability of the current collector 9 after installation. Furthermore, through the coordinated use of the fixing cylinder 17, telescopic column 18, second spring 19, sliding groove 22, slider 23, receiving plate 24, and third spring 25, good stability is maintained when the current-carrying slipper 11 swings, and a certain buffering effect is provided, effectively protecting the insulating component 13 and maintaining its stability during use.

[0040] Working principle: When the current collector 9 is brought close to the second mounting bracket 7, the outward pulling of the pull column 908 causes the reset block 907 to move towards the locking block 702, disengaging it from the locking groove 902. Simultaneously, the first spring 909 is compressed and deformed as the pull column 908 moves outward. At this time, the forward extension of the electric push rod 904 pushes the push block 905 to slide inside the open slot 903. The open slot 903 causes the extension seat 901 to move, causing the extension block 701 to engage with the locking groove 902. At this point, the extension block 701 is fully engaged with the locking groove 902. After releasing the pull column 908, the elasticity of the first spring 909 is restored, causing the pull column 908 to move towards the inner side of the circular groove 906. Simultaneously, the reset block 907 also moves towards the locking block 702 until the reset block 907... 7 is fully engaged with the snap-fit ​​block 702. After connecting the current collector 9 to the second mounting bracket 7, the fixing plate 14 and the second mounting bracket 7 are locked and fixed by multiple fastening bolts 15 to maintain the firmness of the connection of the current collector 9. The adjustable swing rod 16 allows the current receiving slipper 11 to abut against the power supply rail 1301, thereby supplying power to the monorail vehicle. While the swing rod 16 is being adjusted, the telescopic column 18 will also extend and retract accordingly, and drive the second spring 19 to stretch or compress and deform. The third spring 25 will also stretch and compress and deform accordingly, thus providing a certain buffering effect on the current receiving slipper 11 during adjustment. Furthermore, when the swing rod 16 is being adjusted, its end can maintain good stability during adjustment because the slider 23 slides inside the slide groove 22.

[0041] The above-described embodiments are merely illustrative of certain implementations of the present invention, and are described in a relatively specific and detailed manner. However, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements are all within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
