[0002] A gas cylinder is a mobile pressure vessel that contains permanent gas, liquefied gas or dissolved gas and can be repeatedly inflated under normal circumstances. It is a pressure-bearing device with explosion hazards. Therefore, the gas cylinder needs to be inspected before it is processed and put into use to ensure its safe use. Special inspection equipment will be used during the inspection.

[0003] For example, publication number CN214426933U discloses a gas cylinder inspection device for special equipment, including a base, a gas injection needle port and a pressure relief block, both sides of the upper surface of the base are fixedly connected with columns, and a sleeve plate is provided in the middle position of the top of the base, and a protective pad is fixedly connected to one side of the limit plate, and a gas cylinder body is provided in the middle position of the upper surface of the base, and a gas injection needle port is provided at the top of the gas cylinder body, and an external conduit is fixedly connected to the top of the gas injection needle port, and a pressure relief block is fixedly connected to one side of the gas injection needle port. The utility model uses a hollow block fixedly connected at both ends of one side of the sleeve plate. When the gas cylinder body explodes, the impact force will push the limit plate to move, so that the limit plate can push the sliding block to slide inside the hollow block through the support rod, and the sliding block squeezes the second spring, and the elastic effect of the second spring will offset the impact force, thereby achieving buffering of the explosion, reducing the power of the explosion, and improving the safety of the equipment when in use.

[0028] refer to Figure 2Two partitions 9 are fixedly connected to the bottom of the inner wall of the connecting groove 72, and protective pads 10 are fixedly connected to the outer sides of the two partitions 9. The outer sides of the protective pads 10 are in contact with the inner side of the surface of the airbag 73, and support plates 11 are fixedly connected to both sides of the inner top of the side panel 71 and the inner side of the partition 9.

[0032] refer to Figure 1 The left and right sides of the conveyor 5 are fixedly connected to a support plate 14, the air injection pump 81 is fixedly installed on the top of the support plate 14, and a control panel 15 is fixedly installed on the right side of the support frame 1. The conveyor 5 and the air injection pump 81 are electrically connected to the control panel 15 through wires.

[0033] As a technical optimization solution of the utility model, by providing a support plate 14 and a control panel 15 , the support plate 14 can support and fix the air injection pump 81 , and the control panel 15 is convenient for the user to control the conveyor 5 and the air injection pump 81 .

[0034] refer to Figure 3 A placement rack 16 is fixedly connected to the rear side of the conveyor 5 , and three positioning grooves 17 are provided at the bottom of the inner wall of the placement rack 16 .

[0036] The working principle and use process of the utility model are as follows: when in use, the external conduit 4 is connected to the external gas source. When it is necessary to inspect the gas cylinder used for the special equipment, the gas cylinder to be inspected is first placed on the top of the placement plate 6, and then the connecting pipe 83 is sleeved on the surface of the air inlet pipe 82. Then, the gas injection pump 81 is started through the control panel 15 to allow the gas to pass through the connecting pipe 83 and the air inlet pipe 82 to fill the inside of the air bag 73. When the volume of the air bag 73 gradually increases, the gas cylinder on the top of the placement plate 6 can be stably positioned. After the inflation is completed, the connecting pipe 83 is separated from the air inlet pipe 82 and a sealing plug is used. The air inlet pipe 82 is sealed, and then the conveyor 5 is started through the control panel 15. At this time, the conveyor belt on the surface of the conveyor 5 can drive the placement plate 6 to move backward. When the gas cylinder moves to the bottom of the gas injection needle port 2, the conveyor is paused through the control panel 15, and then the gas injection needle port 2 is set on the inflation port of the gas cylinder. The gas cylinder can be inflated by starting the external gas source, so that the pressure resistance of the gas cylinder can be tested. After the test, the user can place the gas cylinder on the top of the placement rack 16 for temporary storage, which is more convenient to use. The positioning of the gas cylinder by the air bag 73 is safer.

[0037] To sum up: this gas cylinder inspection equipment for special equipment is equipped with a conveyor 5 and a placement plate 6. The placement plate 6 is used to support the gas cylinder. By starting the conveyor 5, the gas cylinder can be driven to move forward and backward, so that the gas cylinder can stably enter and exit from the bottom of the gas injection needle port 2, which solves the problem that the space between the gas injection needle port and the gas injection bottle is small. Therefore, when the user places the gas cylinder at the bottom of the gas injection needle port or takes it away from the bottom, it is easy to collide with the gas injection needle buckle. After multiple collisions, it is easy to cause looseness between the gas injection needle port and the external catheter, which will cause leakage between the gas injection needle port and the external catheter, and then cause the detection result to be inaccurate.
