DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0027] In addition, this application may repeat reference numbers and / or reference letters in different examples. This repetition is for the purpose of simplicity and clarity and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, this application provides examples of various specific processes and materials, but those of ordinary skill in the art will recognize the application of other processes and / or the use of other materials.

[0028] The laser of the laser welder is excited by a mixture of high helium, nitrogen and carbon dioxide in proportion. The shielding gas used in the strip welding process is low helium. The four gases are stored in gas cylinders, and the cylinder pressure is controlled at 120bar-150bar.

[0029] The operator replaces the gas cylinder according to the residual pressure in the gas cylinder. The height of the mouth of the gas cylinder containing the four gases is flush with the operator's head. When replacing, the moment the gas cylinder valve is opened, the high gas pressure in the gas cylinder will cause an instantaneous pressure shock, which may easily cause damage to the gas cylinder joint or the hose connected to the gas cylinder joint. When the gas pressure in the gas cylinder is instantly ejected or the air pipe is thrown out, the operator will be injured.

[0030] If the inspection personnel check the gas cylinder joints manually, it is possible that the gas cylinder joints may break. The reasons for the breakage of the gas cylinder joints include but are not limited to aging of the gas cylinder joints. Due to the high gas pressure in the gas cylinder, the broken gas cylinder joints may break and injure people, causing harm to the inspection personnel.

[0031] Based on the above problems, the present application provides a safety protection device for a gas cylinder 20. The safety protection device is adaptively designed based on the environment of the gas cylinder rack where the existing gas cylinder 20 is installed. Figure 2The relative relationship between the gas cylinder 20 and the gas cylinder rack 30 is shown. Usually, multiple gas cylinders 20 are installed in the gas cylinder rack 30 to meet the gas requirements of the equipment, such as the gas requirements of the laser welder for high helium, nitrogen, carbon dioxide and low helium. Figure 1 The safety protection device of the present application includes a crossbeam 100 and a clamping member 200 . The crossbeam 100 is installed on the gas cylinder rack 30 . The clamping member 200 is connected to the crossbeam 100 . The clamping member 200 can clamp the gas cylinder connector 21 of the gas cylinder 20 .

[0032] The clamping member 200 clamps the cylinder connector 21 of the gas cylinder 20 to limit the position of the cylinder connector 21, thereby enhancing the position stability of the cylinder connector 21 and improving the defect of damage to the cylinder connector 21 during the replacement of the gas cylinder 20, thereby improving operational safety and reducing potential safety hazards.

[0033] In some embodiments, see Figure 1 The clamp 200 includes a main body 210 and a second half hoop portion 220. The main body 210 includes a rod portion 211 and a first half hoop portion 212. A single main body 210 is provided with one or two first half hoop portions 212, one of which is connected to one end of the rod portion 211, while the other two are connected to both ends of the rod portion 211. The second half hoop portion 220 is configured to mate with the first half hoop portion 212. The second half hoop portion 220 and the first half hoop portion 212 are connected via bolts 230. When the second half hoop portion 220 and the first half hoop portion 212 are mated, a hoop cavity is formed between the second half hoop portion 220 and the first half hoop portion 212. This hoop cavity is the functional area of the clamp 200. When the clamp 200 clamps the gas cylinder connector 21, the gas cylinder connector 21 is inserted into the hoop cavity, and the clamp 200 is tightly fitted around the gas cylinder connector 21.

[0034] Please refer to Figure 1 Two clamping members 200 are provided opposite to each other, and the two clamping members 200 are respectively a first clamping member 241 and a second clamping member 242. One end of the length of the first clamping member 241 clamps the crossbeam 100 through the hoop cavity, at this time forming a limiting relationship between the first clamping member 241 and the crossbeam 100. The other end of the length of the first clamping member 241 clamps the rod 211 of the second clamping member 242 through the hoop cavity, at this time forming a limiting relationship between the first clamping member 241 and the second clamping member 242. One end of the length of the second clamping member 242 clamps the gas cylinder connector 21 through the hoop cavity, at this time forming a limiting relationship between the second clamping member 242 and the gas cylinder connector 21. The crossbeam 100, the first clamping member 241, the second clamping member 242 and the gas cylinder connector 21 cooperate with each other to achieve stable clamping of the gas cylinder connector 21.

[0035] The embodiment including the clamping member 200 can be adapted to the use of gas cylinders 20 of different heights. For example, in a laser welding machine, the heights of the multiple gas cylinders 20 are different due to the different media and pressures filled in the gas cylinders 20. The heights of the gas cylinder joints 21 of each gas cylinder 20 are also different. The crossbeam 100 is generally installed in the horizontal direction, so the spatial postures of the multiple clamping members clamping the gas cylinder joints 21 are different. Please refer to Figure 1 By adopting an embodiment including the above-mentioned clamping member 200, the relative angle between the first clamping member 241 and the crossbeam 100 can be adjusted before the first clamping member 241 clamps the crossbeam 100, and the relative angle between the second clamping member 242 and the gas cylinder connector 21 can also be adjusted, so that the clamping member 200 can smoothly realize the function of clamping gas cylinder connectors 21 of different heights based on the crossbeam 100 of the same height.

[0036] In some embodiments, see Figure 1 The first half hoop portion 212 and the second half hoop portion 220 are both square components with two parallel mounting holes. The mounting holes pass through the square component and form a groove 221 on one side of the thickness of the square component. The first half hoop portion 212 and the second half hoop portion 220 are installed in the mounting holes by bolts 230 to achieve the docking of the first half hoop portion 212 and the second half hoop portion 220. When the first half hoop portion 212 and the second half hoop portion 220 are docked, the groove 221 of the first half hoop portion 212 is opposite to the groove 221 of the second half hoop portion 220 and forms the above-mentioned hoop cavity.

[0037] In some embodiments, a pipe clamp in an existing product is used as an embodiment of the first half hoop portion 212 and the second half hoop portion 220 .

[0038] In some embodiments, the rod 211 is an iron pipe, which has a hollow structure and can reduce the weight of the clamp 200 .

[0039] In some embodiments, the length direction of the crossbeam 100 is limited, and at least one row of gas cylinders 20 is installed on the gas cylinder rack 30. The multiple gas cylinders 20 in each row of gas cylinders 20 have an arrangement direction. The length direction of the crossbeam 100 is the same as the arrangement direction of the multiple gas cylinders 20, which facilitates the gas cylinder connectors 21 of the multiple gas cylinders 20 in each row of gas cylinders 20 to be clamped separately by multiple clamps 200.

[0040] In some embodiments, the cross beam 100 is welded to the gas cylinder rack 30 .

[0041] In some embodiments, see Figure 2The safety protection device also includes a track 300 and a protective plate 400. The track 300 is mounted on the gas cylinder rack 30 and is higher than the gas cylinder 20 on the gas cylinder rack 30. The protective plate 400 is movably mounted on the track 300. The protective plate 400 is closer to the gas cylinder 20 than the track 300. When manually replacing the gas cylinder 20, the protective plate 400 is located between the gas cylinder 20 and the operator. When the operator replaces the gas cylinder 20, the protective plate 400 is moved between the gas cylinder connector 21 and the operator. The protective plate 400 protects the operator's face from injury and prevents injuries caused by the gas cylinder connector 21 breaking.

[0042] A specific operation method is provided here: 1) When replacing the gas cylinder 20, push and pull the protective plate 400 to the empty bottle position, close the valve of the gas cylinder 20 of the empty bottle, open the exhaust valve to exhaust, and remove the connecting hose between the empty bottle and the gas exhaust; 2) After the disassembly is completed, push the protective plate 400 to the idle position, swap the empty bottle with the full bottle, connect the hose with the full bottle, and clamp the hose with the clamping part 200; 3) Push and pull the protective baffle to the full bottle position, hold the protective plate 400 with your left hand, and screw the valve of the gas cylinder 20 of the full bottle with your right hand to open the full bottle. After the air pipe is pressurized, perform a leak test to ensure the air tightness of the pipeline.

[0043] The above operation method can be written on paper and pasted on the protective plate 400 to visualize the operation method.

[0044] In some embodiments, see Figure 2 The track 300 is installed on the frame 310 , the frame 310 and the gas cylinder rack 30 are fixedly connected, and the track 300 is installed on the gas cylinder rack 30 through the frame 310 .

[0045] In some embodiments, see Figure 3 The track 300 is two parallel rails connected to the frame 310. The protective plate 400 is installed on the two rails, and the protective plate 400 is located in the interval area between the two rails. The protective plate 400 moves along the length direction of the rails.

[0046] In some embodiments, rollers are installed on opposite sides of the protective plate 400 , and the rollers are rollingly mounted on the track 300 , and the protective plate 400 is movably mounted on the rail via the rollers.

[0047] It should also be noted that the safety protection device for the gas cylinder 20 of the present application has been used in high-pressure gas cylinders 20 in fields such as laser welding machines, effectively reducing the operational risk of being hit by objects when replacing the gas cylinder 20 and reducing safety accidents.

[0048] In this application, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
