Description

Technical Field

[0001] This utility model relates to the field of power engineering, and in particular to a long-distance lateral-moving mobile contact network discharge buffer device. Background Technology

[0002] The long-distance intelligent side-shifting mobile contact network body is used on railway outdoor loading and unloading lines to meet the needs of direct traction and departure of electric locomotives. During loading and unloading operations, the contact network can be manually moved to the support side (hereinafter referred to as "removal") to free up space above the line for loading and unloading goods. After loading and unloading is completed, the contact network is restored to the line side (hereinafter referred to as "entry"), thus enabling direct traction and departure of electric locomotives. The rated operating voltage of the mobile contact network body is AC27.5kV, so when in the "entry" position, the entire mobile contact network body carries AC27.5kV voltage. After removal, the entire mobile contact network body is disconnected from the power supply device. At this time, the contact network still carries residual charge, and the movement of the mobile contact network body during the removal process is relatively large, requiring external force to slowly stop it. Existing long-distance lateral-shifting mobile contact network body discharge buffer devices generally do not have a buffer device. When the mobile contact network body moves from the in-line position to the out-of-line position, it will cause an impact. Long-term use will lead to damage to the components and cause certain losses. Therefore, we propose a long-distance lateral-shifting mobile contact network discharge buffer device. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a long-distance side-shifting mobile contact wire discharge buffer device. After the contact plate comes into contact with the mobile contact wire body, the buffer spring in the discharge buffer device is continuously compressed as the mobile contact wire body moves, so as to achieve the functions of discharge and buffering, reduce the impact caused by movement, and protect the device as a whole.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A long-distance lateral-shifting mobile contact network discharge buffer device includes a bracket, a mobile contact network body is installed on the left side of the outer end of the bracket, a fixing mechanism is installed on the right side of the outer end of the bracket, and a buffer mechanism is fixedly installed on the outer side of the fixing mechanism. The buffer mechanism includes a spring guide cylinder, with a guide cylinder mounting base connected to the outer end of the spring guide cylinder. A set of mounting bolts is installed on the outer end of the guide cylinder mounting base. An insulator is fixedly connected to the end of the guide cylinder mounting base, and a connecting ring is fixedly connected to the end of the insulator. A spring mounting base is provided on the inner side of the inner end of the spring guide cylinder, and a buffer spring is fixedly installed on the inner side of the inner end of the spring mounting base. A sleeve damper is fixedly connected to the front end of the buffer spring, and a discharge shaft is fixedly connected to the front end of the sleeve damper. A contact plate is fixedly connected to the front end of the discharge shaft. When the moving contact network body moves from the in-line position to the out-of-line position, the moving contact network body will contact the contact plate and move. The contact plate connects to the discharge shaft and conducts residual charge to the ground. After the contact plate contacts the moving contact network body, the buffer spring in the discharge buffer device is continuously compressed as the moving contact network body moves, ultimately achieving the functions of discharge and buffering. This reduces the impact caused during movement and protects the entire device.

[0005] Furthermore, the fixing mechanism includes a mounting plate with a mounting hole at the center of its front end. A connecting rod is connected through the front side of the mounting plate, and a connecting plate is fixedly connected to the end of the connecting rod. By setting the connecting rod and the mounting plate, the buffer component is supported and fixed, improving the convenience of using the device.

[0006] Furthermore, the connecting ring is fixedly installed at the front center of the mounting plate, and the mounting bolt group is connected to the mounting hole. By setting the mounting bolt group, the installation connection work is carried out, which makes the device easy to install and disassemble, and improves the convenience of using the device.

[0007] Furthermore, there are two guide cylinder mounting seats, which are installed side by side. The guide cylinder mounting seats are adapted to the spring guide cylinder. By setting the guide cylinder mounting seats to fix and support the spring guide cylinder, the stability of the device during use is improved.

[0008] Furthermore, there are four connecting rods, which are arranged in pairs, with their ends passing through the mounting plate and the connecting plate respectively, and are fixed by bolts.

[0009] Furthermore, the number of mounting holes is several, and the positions of the mounting holes correspond to the mounting bolt groups on the connecting ring.

[0010] Furthermore, the number of insulators is two, and the two insulators have a spiral structure.

[0011] Furthermore, the discharge shaft is nested inside the spring guide cylinder, and the discharge shaft can be retracted to the inner end of the spring guide cylinder by compressing the buffer spring.

[0012] In summary, this utility model has the following beneficial effects: 1. By setting a contact plate, when the mobile contact wire body moves from the in-line position to the out-of-line position, the mobile contact wire body will contact the contact plate and move. The contact plate is connected to the discharge shaft and conducts the residual charge to the ground. After the contact plate contacts the mobile contact wire body, the buffer spring in the discharge buffer device is continuously compressed as the mobile contact wire body moves, and finally achieves the function of discharge and buffering. This can reduce the impact caused during movement and protect the overall device. The buffer component is supported and fixed by setting a connecting rod and a mounting plate, which improves the convenience of the device during use. 2. By setting up a guide cylinder mounting seat to fix and support the spring guide cylinder, the stability of the device during use is improved. By setting up a set of mounting bolts for installation and connection, the device is easy to install and disassemble, thus improving the convenience of use. Attached Figure Description

[0017] Reference Figure 1-5As shown, a long-distance lateral-moving mobile contact network discharge buffer device is provided in a preferred embodiment of the present invention. It includes a bracket 1, a mobile contact network body 2 installed on the left side of the outer end of the bracket 1, a fixing mechanism 3 installed on the right side of the outer end of the bracket 1, and a buffer mechanism 4 fixedly installed on the outer side of the fixing mechanism 3. The buffer mechanism 4 includes a spring guide cylinder 401, with a guide cylinder mounting base 402 connected to its outer end. A mounting bolt assembly 403 is mounted on the outer end of the guide cylinder mounting base 402. An insulator 404 is fixedly connected to the end of the guide cylinder mounting base 402, and a connecting ring 405 is fixedly connected to the end of the insulator 404. A spring mounting base 406 is provided on the inner side of the inner end of the spring guide cylinder 401, and a buffer spring 407 is fixedly mounted on the inner side of the inner end of the spring mounting base 406. A sleeve damper 408 is fixedly connected to the front end of the buffer spring 407. A discharge shaft 409 is fixedly connected, and a contact plate 410 is fixedly connected to the front end of the discharge shaft 409. When the mobile contact wire body 2 moves from the wire-entry position to the wire-exit position, the mobile contact wire body 2 will contact the contact plate 410 and move. The contact plate 410 is connected to the discharge shaft 409 and conducts the residual charge to the ground. After the contact plate 410 contacts the mobile contact wire body 2, the buffer spring 407 in the discharge buffer device is continuously compressed as the mobile contact wire body 2 moves, and finally achieves the functions of discharge and buffering, which can reduce the impact caused during movement and protect the entire device.

[0018] Reference Figure 1-3 As shown, the fixing mechanism 3 includes a mounting plate 301. A mounting hole 302 is provided in the middle of the front end of the mounting plate 301. A connecting rod 303 is connected through the front side of the mounting plate 301. A connecting plate 304 is fixedly connected to the end of the connecting rod 303. There are four connecting rods 303. The four connecting rods 303 are arranged in pairs, and their ends pass through the mounting plate 301 and the connecting plate 304 respectively and are fixed by bolts. There are several mounting holes 302. The positions of the mounting holes 302 correspond to the mounting bolt group 403 on the connecting ring 405. By setting the connecting rods 303 and the mounting plate 301, the buffer component is supported and fixed, improving the convenience of the device during use.

[0019] Reference Figure 3-4As shown, the connecting ring 405 is fixedly installed at the front center of the mounting plate 301. The mounting bolt group 403 is connected to the mounting hole 302. There are two insulators 404, which are spiral structures. The discharge shaft 409 is nested in the inner end of the spring guide cylinder 401. The discharge shaft 409 can be compressed into the inner end of the spring guide cylinder 401 by the buffer spring 407. The impact generated by the device is absorbed by the buffer spring 407 and the sleeve damper 408, which reduces the impact and damage and improves the service life of the device. The mounting bolt group 403 is used for installation and connection, which makes the device easy to install and disassemble and improves the convenience of use.

[0020] Reference Figure 3-4 As shown, there are two guide cylinder mounting seats 402, which are installed side by side. The guide cylinder mounting seats 402 are adapted to the spring guide cylinder 401. By setting the guide cylinder mounting seats 402 to fix and support the spring guide cylinder 401, the stability of the device during use is improved.

[0021] Specific implementation process: When the mobile contact wire body 2 moves from the in-line position to the out-of-line position, it first contacts the contact plate 410. After contact, the residual charge on the mobile contact wire body 2 is transferred through the contact plate 410 to the discharge shaft 409 fixedly connected to it, and is conducted to the ground through the discharge shaft 409 and the ground wire, completing the discharge process. As the mobile contact wire body 2 continues to move towards the out-of-line position, the contact plate 410 is continuously pushed, thereby driving the discharge shaft 409 to move towards the inner end of the spring guide cylinder 401. Since the front end of the discharge shaft 409 is fixedly connected to the sleeve damper 408, and the sleeve damper 408 is connected to the buffer spring 407, and the buffer spring... Spring 407 is fixed on spring mounting base 406. Therefore, the movement of discharge shaft 409 will cause buffer spring 407 to be continuously compressed. At the same time, sleeve damper 408 works together to absorb the impact generated during the movement of mobile contact network body 2. During this process, a stable support is formed through the cooperation of mounting plate 301, four connecting rods 303 and connecting plate 304. The connecting ring 405 and mounting bolt group 403 are fixedly connected to the mounting hole 302 on mounting plate 301. Guide cylinder mounting base 402 fixes spring guide cylinder 401. Insulator 404 ensures insulation performance and ensures that the entire discharge and buffering process is stable, ultimately achieving protection of the device.
