Then, the feeding transmission assembly stops, the ferry assembly feeds, the ferry assembly enters the gas cylinder slot, and sends the gas cylinder into the inner side of the explosion-proof pipe seat. Then, the first hydraulic cylinder drives the push seat upward to the set height. At this time, the ferry assembly enters the I-shaped slot, and the bottom of the gas cylinder is separated from the ferry assembly. At this time, the gas cylinder is received by the push seat. The ferry assembly resets and detaches from the gas cylinder slot. The first hydraulic cylinder drives the push seat to reset.

The second hydraulic cylinder moves upward, and the gas cylinder with quality problems is manually separated from the explosion-proof pipe socket; then, according to the above process, a new gas cylinder is put into the explosion-proof pipe socket for refilling. When the gas concentration detector detects no leakage, the filling nozzle supplies gas to the filling head. After the gas cylinder is filled, the gas supply pipe is locked. At this time, the second hydraulic cylinder moves upward, and the pressure transmitter detects that the pressure is lower than the set value. The filling head is separated from the gas cylinder filling port. At this time, the explosion-proof outer tube is still in a closed state on the gas cylinder notch; then, the vacuum pump works to discharge or collect the overflowed industrial gas;

[0024] The gas cylinder is unloaded, the second hydraulic cylinder continues to move upward, the explosion-proof outer cylinder is reset, and the first hydraulic cylinder drives the push seat upward; the ferry assembly enters the gas cylinder slot, and then enters the I-shaped slot; at this time, the push seat descends, and the gas cylinder is pressed onto the ferry assembly, and the ferry assembly continues to move forward, sending the gas cylinder to the discharging transmission assembly, and the ferry assembly is separated from the gas cylinder and reset; the discharging transmission assembly discharges the filled gas cylinder; after one gas cylinder is filled and unloaded, the new gas cylinder is filled again according to the above process.

7. An industrial gas filling process, using the industrial gas filling system according to claim 1, characterized in that: The process is specifically as follows: Gas cylinder feeding: Place the gas cylinder to be filled on the feeding transmission assembly. The two sides of the gas cylinder are limited by the inner side of the feeding transmission assembly and are transmitted to the ferry assembly through the feeding transmission assembly. Then, the feeding transmission assembly stops, the ferry assembly feeds, the ferry assembly enters the gas cylinder slot, and sends the gas cylinder into the inner side of the explosion-proof pipe seat. Then, the first hydraulic cylinder drives the push seat upward to the set height. At this time, the ferry assembly enters the I-shaped slot, and the bottom of the gas cylinder is separated from the ferry assembly. At this time, the gas cylinder is received by the push seat. The ferry assembly resets and detaches from the gas cylinder slot. The first hydraulic cylinder drives the push seat to reset. In preparation for filling, the second hydraulic cylinder retracts, driving the explosion-proof outer cylinder downward along the explosion-proof pipe seat. At this time, the explosion-proof outer cylinder seals the notch of the gas cylinder, and due to the action of the spring body, the straightening cylinder is sleeved and pressed against the upper part of the gas cylinder; thus, a closed upper space is formed on the upper part of the outer side of the gas cylinder; then, the vacuum pump is activated to evacuate the upper space through the vacuum pipe and vacuum nozzle; During industrial gas filling, the second hydraulic cylinder continues to retract, driving the explosion-proof outer cylinder to continue to descend along the explosion-proof pipe seat. When the pressure transmitter detects the set pressure, the second hydraulic cylinder locks. At this time, under a vacuum environment, the inflation head is pressed against the inflation port of the gas cylinder to complete the docking. The vacuum pump is turned off. At this time, the industrial gas source is pre-filled to the inflation nozzle through the gas supply pipe; a certain amount of industrial gas is sent into the gas cylinder. At this time, when the gas concentration detector detects a leak, it sends a leak alarm signal, and the vacuum pump is turned on again to extract the leaked industrial gas. The second hydraulic cylinder is manually triggered. The second hydraulic cylinder moves upward, and the gas cylinder with quality problems is manually separated from the explosion-proof pipe socket; then, according to the above process, a new gas cylinder is put into the explosion-proof pipe socket for refilling. When the gas concentration detector detects no leakage, the filling nozzle supplies gas to the filling head. After the gas cylinder is filled, the gas supply pipe is locked. At this time, the second hydraulic cylinder moves upward, and the pressure transmitter detects that the pressure is lower than the set value. The filling head is separated from the gas cylinder filling port. At this time, the explosion-proof outer tube is still in a closed state on the gas cylinder notch; then, the vacuum pump works to discharge or collect the overflowed industrial gas; The gas cylinder is unloaded, the second hydraulic cylinder continues to move upward, the explosion-proof outer cylinder is reset, and the first hydraulic cylinder drives the push seat upward; the ferry assembly enters the gas cylinder slot, and then enters the I-shaped slot; at this time, the push seat descends, and the gas cylinder is pressed onto the ferry assembly, and the ferry assembly continues to move forward, sending the gas cylinder to the discharging transmission assembly, and the ferry assembly is separated from the gas cylinder and reset; the discharging transmission assembly discharges the filled gas cylinder; after one gas cylinder is filled and unloaded, the new gas cylinder is filled again according to the above process.
