Description

Technical Field

[0001] This application relates to the field of maintenance vehicles, and more particularly to a mobile tracked converter station mast maintenance vehicle. Background Technology

[0002] The core function of a converter station is to convert alternating current (AC) to direct current (DC) (rectification) or direct current (DC) to AC (inversion). This conversion is the foundation of high-voltage direct current (HVDC) transmission, meeting the power system's requirements for safety, stability, and power quality. In a HVDC transmission system, the sending-end converter station is responsible for converting AC power generated by the power plant into DC power for transmission, while the receiving-end converter station converts DC power back into AC power for feedback into the local power grid. Converter stations include various key equipment, such as converter valves, converter transformers, smoothing reactors, AC filters, DC filters, and control and protection devices. These devices work together to ensure the high efficiency and stability of power conversion. Converter stations are equipped with masts for mounting equipment such as antennas. Mobile tracked maintenance vehicles are commonly used to inspect the equipment on the mast. In conventional mobile tracked maintenance vehicles, the vehicle body moves via tracks, and a lifting frame is mounted on one end of the vehicle body using a robotic arm. After the vehicle body moves to the location to be inspected, the robotic arm controls the lifting frame to move to the vicinity of the mast, facilitating maintenance by personnel.

[0003] Regarding the aforementioned technologies, the inventors believe that when conventional mobile tracked maintenance vehicles are in use, the lifting frame is often lifted by a robotic arm. When the robotic arm is lifted a long distance from the vehicle body, the upper part of the lifting frame is prone to swaying or even tilting due to the weight of the workers and their tools, causing inconvenience for workers operating at heights.

[0004] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0005] To address the issue of swaying in mobile tracked maintenance vehicles after the lifting frame is raised, this application provides a mobile tracked converter station mast maintenance vehicle.

[0006] The technical solution for the mobile tracked converter station mast maintenance vehicle provided in this application is as follows:

[0007] A mobile tracked converter station mast maintenance vehicle includes a vehicle body and a slide rail. Two mobile tracks are driven to the bottom of the vehicle body, and a robotic arm is rotatably connected to the top of the vehicle body. A lifting frame is fixedly installed at one end of the robotic arm. Two adjusting blocks are slidably connected to the surface of the slide rail. A telescopic rod is fixedly installed at one end of each adjusting block, and a limit frame is fixedly connected to one end of each telescopic rod. The dimensions of the inner wall of the adjusting block are adapted to the dimensions of the slide rail surface. The top of the slide rail is fixedly connected to the bottom of the lifting frame, and the limit frame has a "C" shaped cross-section.

[0008] Preferably, a rotary motor is fixedly installed at one end of the slide rail, and a control switch is electrically connected to one end of the rotary motor via a wire. The bottom end of the control switch is fixedly installed to the top of the lifting frame. A threaded rod is fixedly connected to the output end of the rotary motor. The surface of the threaded rod is threaded onto the inner wall of the adjusting block, and the center of the threaded rod is on the same straight line as the center of the rotary motor.

[0009] Preferably, the surface of the threaded rod has two threaded grooves, which are symmetrically distributed about the threaded rod, and the inner wall of the threaded grooves is threadedly connected to the inner wall of the adjusting block.

[0010] Preferably, the inner wall of the adjusting block is rotatably equipped with a plurality of pulleys, which are divided into two groups. The two groups of pulleys are symmetrically distributed about the adjusting block, and the surfaces of the pulleys are slidably connected to the surfaces of the slide rails.

[0011] Preferably, the telescopic rod is composed of an adjusting cylinder and an adjusting rod, the dimensions of the adjusting rod surface are adapted to the dimensions of the inner wall of the adjusting cylinder, and the center of the telescopic rod and the center of the adjusting block are on the same straight line.

[0012] Preferably, a fixing bolt is threaded onto the top of the telescopic rod, and the fixing bolt is perpendicular to the telescopic rod.

[0013] Preferably, one end of the limiting frame is fixedly connected to a limiting ring, the size and specifications of the limiting ring surface are adapted to the size and specifications of the limiting frame surface, and the limiting ring is a rubber ring.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By installing a slide rail at the bottom of the lifting frame, an adjusting block is slidably connected to the surface of the slide rail. One end of the adjusting block is equipped with a limit bracket via a telescopic rod, which allows the limit bracket at one end of the telescopic rod to engage with the surface of the mast, preventing the lifting frame from swaying or even tilting after lifting. A rotary motor is installed on the surface of the slide rail, and one end of the rotary motor is connected to a control switch via a wire. A threaded rod is installed at the output end of the rotary motor, so that after the rotary motor is started by the control switch, the threaded rod can be used to fix the limit bracket in a suitable position. Two threaded grooves are formed on the surface of the threaded rod, which allows for easy control of the adjusting blocks to move away from or closer to each other. Several pulleys are rotatably connected to the inner wall of the adjusting block, which reduces the friction between the adjusting block and the slide rail. Compared with existing technologies, this effectively improves the stability of the mobile tracked maintenance vehicle.

[0016] 2. Alternatively, a telescopic rod can be installed at one end of the limiting frame. The telescopic rod consists of an adjusting cylinder and an adjusting rod, which allows the position of the limiting frame to be adjusted according to the position of the mast. The surface of the telescopic rod is threaded with fixing bolts, which are used to fix the length of the telescopic rod. One end of the limiting frame is equipped with a rubber limiting ring, which enhances the fixing effect of the limiting frame and effectively improves the use effect of the device.

[0022] The following is in conjunction with the appendix Figure 1 —4. This application will be described in further detail.

[0023] This application discloses a mobile tracked converter station mast maintenance vehicle, referring to... Figure 1 - Figure 2The system includes a testing vehicle body 1. During use, the testing vehicle body 1 moves via a mobile track 2. A lifting frame 4 is mounted on one end of the testing vehicle body 1 via a robotic arm 3. After the testing vehicle body 1 moves to the position to be inspected, the lifting frame 4 is moved to the periphery of the mast by the robotic arm 3, thus facilitating maintenance by personnel. A slide rail 5 is installed at the bottom of the lifting frame 4. An adjusting block 6 is slidably connected to the surface of the slide rail 5. A limit frame 8 is mounted on one end of the adjusting block 6 via a telescopic rod 7. By sliding the adjusting block 6 on the surface of the slide rail 5, the limit frame 8 at one end of the telescopic rod 7 is engaged with the surface of the mast, thereby fixing one end of the lifting frame 4. This effectively improves the stability of the mobile track 2 type maintenance vehicle and prevents the lifting frame 4 from shaking or even tilting after being lifted.

[0024] Reference Figure 2 A rotary motor 11 is mounted on the surface of the slide rail 5. One end of the rotary motor 11 is connected to a control switch 12 via a wire, and a threaded rod 9 is mounted on the output end of the rotary motor 11. The surface of the threaded rod 9 is threadedly connected to the inner wall of the adjusting block 6. After the rotary motor 11 is started by the control switch 12, the threaded rod 9 at the output end of the rotary motor 11 rotates and adjusts the position of the adjusting block 6, thereby fixing the limit frame 8 in a suitable position. Two threaded grooves 10 are opened on the surface of the threaded rod 9, which facilitates the adjustment of the two adjusting blocks 6, allowing the adjusting blocks 6 to move away from or closer to each other, making it more convenient to use. Several pulleys 13 are rotatably connected to the inner wall of the adjusting block 6. The surface of the pulleys 13 is slidably connected to the surface of the slide rail 5, which reduces the friction between the adjusting block 6 and the slide rail 5, making it more convenient to move the adjusting block 6.

[0025] Reference Figure 3 - Figure 4 The telescopic rod 7 is installed at one end of the limiting frame 8. The telescopic rod 7 consists of an adjusting cylinder and an adjusting rod. The adjusting rod slides inside the adjusting cylinder, which facilitates the adjustment of the position of the limiting frame 8 at one end of the telescopic rod 7. The position of the limiting frame 8 can be adjusted according to the position of the mast. The surface of the telescopic rod 7 is threaded with a fixing bolt 14. The length of the telescopic rod 7 is fixed by the fixing bolt 14, thereby improving the stability of the limiting frame 8 after installation. A rubber limiting ring 15 is installed at one end of the limiting frame 8. The limiting ring 15 increases the friction between the limiting frame 8 and the surface of the mast, thereby improving the fixing effect of the limiting frame 8.

[0026] The implementation principle of a mobile tracked converter station mast maintenance vehicle according to an embodiment of this application is as follows: A slide rail 5 is installed at the bottom of a lifting frame 4. An adjusting block 6 is slidably connected to the surface of the slide rail 5. One end of the adjusting block 6 is equipped with a limit frame 8 via a telescopic rod 7, allowing the adjusting block 6 to slide on the surface of the slide rail 5. This causes the limit frame 8 at one end of the telescopic rod 7 to engage with the mast surface, thereby fixing one end of the lifting frame 4 and preventing swaying or even tilting of the lifting frame 4 after lifting. A rotary motor 11 is installed on the surface of the slide rail 5. One end of the rotary motor 11 is connected to a control switch 12 via a wire, and a threaded rod 9 is installed at the output end of the rotary motor 11. The surface of the threaded rod 9 is connected to the mast surface. The inner wall of the adjusting block 6 is threaded, so that after the control switch 12 starts the rotating motor 11, the threaded rod 9 at the output end of the rotating motor 11 rotates and adjusts the position of the adjusting block 6, thereby fixing the limit frame 8 in a suitable position. The surface of the threaded rod 9 has two threaded grooves 10, so that the two adjusting blocks 6 can be adjusted by means of the threaded grooves 10, and the adjusting blocks 6 can be moved away from or closer to each other, which is more convenient when using. Several pulleys 13 are rotatably connected to the inner wall of the adjusting block 6. The surface of the pulleys 13 is slidably connected to the surface of the slide rail 5, so as to reduce the friction between the adjusting block 6 and the slide rail 5, making it more convenient to move the adjusting block 6.

[0027] The telescopic rod 7 can also be installed at one end of the limiting frame 8. The telescopic rod 7 consists of an adjusting cylinder and an adjusting rod, which allows the adjusting rod to slide inside the adjusting cylinder, making it easy to adjust the position of the limiting frame 8 at one end of the telescopic rod 7. The position of the limiting frame 8 can be adjusted according to the position of the mast. The surface of the telescopic rod 7 is threaded with fixing bolts 14, which can be used to fix the length of the telescopic rod 7, thereby improving the stability of the limiting frame 8 after installation. One end of the limiting frame 8 is equipped with a rubber limiting ring 15, which can be used to increase the friction between the limiting frame 8 and the surface of the mast, thereby improving the fixing effect of the limiting frame 8.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
