[0026] See also Figure 1 and Figure 2 The air supply system of the busbar lifting frame of the utility model includes an air intake mechanism 1, an air intake pipeline 203 and an electric control box (not shown in the figure). The air intake mechanism 1 includes a first connector 11, a filter 12, a pressure reducing filter 13, a booster pump 14, a one-way valve 18 and an air storage tank 15 which are connected in series in sequence. The air intake pipeline 203 is connected to the air outlet of the oil mist device 201, and the air inlet of the oil mist device 201 is connected to the air storage tank 15. Furthermore, four air storage tanks 15 are provided, and the four air storage tanks 15 are connected. The air storage tank 15 is connected to the oil mist device 16.
[0027] The air storage tank 15 is connected to a tensioning motor solenoid valve 19 , and a tensioning motor 18 is connected to the tensioning motor solenoid valve 19 .
[0028] The gas storage tank 15 is also connected to the third pipeline 66. The third pipeline 66 is provided with a fifth solenoid valve 67. The gas outlet of the fifth solenoid valve 67 is connected to the second soot blowing pipe 65. The fifth solenoid valve 67 is electrically connected to the electric control box.
[0029] The air intake mechanism 1 is connected to the air intake pipeline 203 through the oil mist device 201. The air intake pipeline 203 is provided with a first solenoid valve 21 and a second solenoid valve 22. The first air intake port of the first solenoid valve 21 is connected to the air intake pipeline 203. The second air intake port of the second solenoid valve 22 is connected to the air intake pipeline 203. The first air outlet of the first solenoid valve 21 is connected to the first cylinder group upper cavity pipeline 63. The second air outlet of the first solenoid valve 21 is connected to the first cylinder group lower cavity pipeline 64. The third air outlet of the second solenoid valve 22 is connected to the second cylinder group pipeline 55. The electric control box is electrically connected to the first solenoid valve 21 and the second solenoid valve 22.
[0030] The air supply system further includes a first cylinder 61 , an upper chamber of the first cylinder 61 is connected to an upper chamber pipeline 63 of the first cylinder group, and a lower chamber of the first cylinder is connected to a lower chamber pipeline 64 of the first cylinder group.
[0031] The first solenoid valve 21 is a center-sealed solenoid valve. The first cylinder of the first cylinder group 61 of this embodiment uses the self-locking cylinder of the utility model patent CN216951092U. When the first cylinder 61 is inflated, the piston of the first cylinder 61 moves and the self-locking component acts at the same time, but the simultaneous action of the piston and the self-locking component may cause the piston and the self-locking component to be stuck at the same time. When using a center-sealed solenoid valve, the gas in the lower chamber of the first cylinder 61 is not discharged quickly, and there is still gas in the lower chamber of the first cylinder 61. At this time, the piston does not move downward quickly. At this time, the upper chamber of the first cylinder 61 is inhaled and there is air pressure. The self-locking component of the first cylinder 61 is unlocked first, and then the piston of the first cylinder 61 moves downward again, solving the problem of the piston and the self-locking component being stuck at the same time.
[0032] The first cylinder group lower chamber pipeline 64 is also provided with a third solenoid valve 62, which is electrically connected to the electric control box. The third solenoid valve 62 can exhaust gas, and when the lower chamber of the first cylinder 61 is kept full of gas, the lower chamber of the first cylinder 61 can be exhausted to make the piston of the first cylinder 61 descend.
[0033] The second cylinder group includes a quick exhaust valve 31, the air inlet of the quick exhaust valve 31 is connected to the second cylinder group pipeline 55, the first outlet of the quick exhaust valve 31 is connected to the second cylinders 33 and 34, and the second outlet of the quick exhaust valve 31 is connected to the first soot blowing pipe 32. The second cylinders 33 and 34 are a clamping cylinder 33 and a holding cylinder 34 connected in parallel.
[0034] The second cylinder group pipeline 55 is also provided with a pressure sensor 51, which is connected to the electric control box. The intake pipeline 203 is provided with a fourth solenoid valve 221, which is electrically connected to the electric control box. The pressure sensor 51 can detect pressure, and when the pressure is abnormal, the fourth solenoid valve 221 is controlled to exhaust air to prevent excessive pressure from damaging the air supply system.
[0035] See also Figure 3 The first pneumatic port of the first solenoid valve 21 is connected to the first pneumatic pipeline 45, and the second pneumatic port of the second solenoid valve 22 is connected to the second pneumatic pipeline 35. Figure 3 The first pneumatic pipeline 45 is connected to the first knob valve 42, the second pneumatic pipeline 35 is connected to the second knob valve 43, the first knob valve 43 and the second knob valve 42 are connected to the first air port of the main ball valve 41, and the second air port of the main ball valve 41 is connected to the air intake pipeline. The main ball valve 41, the first knob valve 42 and the second knob valve 43 are arranged in the air control box 4.
[0036] The first solenoid valve 21 and the second solenoid valve 22 refer to the solenoid valves in the invention patent application publication number CN 112944011A. When the power supply system loses power, the staff opens the main ball valve 41, the first knob valve 43 and the second knob valve 42 to allow air to enter the first pneumatic pipeline 45 and the second pneumatic pipeline 35, so that the first solenoid valve 21 and the second solenoid valve 22 continue to work, ensuring the overall operation of the air supply system and preventing damage to the bus lifting frame caused by the failure of the air supply system to work.
