Description

Technical Field

[0001] The invention relates to the technical field of gas cylinder inflation, in particular to a mobile gas cylinder inflation device. Background Art

[0002] A gas cylinder is a mobile pressure container for gas or dissolved gas that can be repeatedly inflated and used under normal conditions. For example, gas cylinders are commonly used in industry to hold gases such as oxygen, nitrogen, and hydrogen, and in life to hold natural gas. Gas cylinders commonly used in life generally include a bottle body, a valve seat is fixed to the open end of the bottle body, a valve is installed in series in the connecting pipe connected to the valve seat, a hand wheel for regulating the opening and closing of the valve is rotatably connected to the top of the valve, and a gas pipeline for inflation and exhaust is fixed to the outside of the connecting pipe (refer to the instruction manual Fig.11 );

[0003] When the gas cylinder is inflated, it is necessary to connect and fix the external inflation pipeline with the gas delivery pipe on the gas cylinder, and then turn the hand wheel to connect the connecting pipe on the gas cylinder with the gas delivery pipe. Then the external gas tank will fill the gas into the gas cylinder through the gas delivery pipe. After the gas cylinder is full of gas, turn the hand wheel by hand to seal the connecting pipe on the gas cylinder to prevent gas leakage.

[0004] At present, most inflation devices generally require manual connection of the inflation pipe and the gas supply pipe, manual rotation of the hand wheel during the inflation process to control the flow of gas in the pipe on the gas cylinder, and manual observation of the inflation volume displayed on the inflation meter to determine whether to stop inflation. These operating procedures increase the manpower input in the inflation process, and the inflation device has a low degree of automation, resulting in poor inflation efficiency. After the inflation is completed, the small amount of gas remaining in the inflation pipe and the gas supply pipe is not easy to be collected. When these residual gases leak into the inflation workshop, they are likely to cause safety accidents, reducing the safety of the inflation device. Summary of the invention

[0011] Furthermore, a clamping block is fixed on the outer side of the cylinder shell 1, a connecting block made of iron material is fixed on the outer side of the clamping block, and a sliding groove for slidingly engaging with the clamping block is provided on the outer side of the carrier plate.

[0012] Further, a return spring is fixed between the bottom surface of the support plate and the top surface of the carrier plate, a suction cup is embedded and fixed on the top surface of the support plate, and the return spring is sleeved on the outside of the telescopic pipe.

[0013] Furthermore, the telescopic pipe comprises a sleeve fixedly connected to the carrier plate, and the interior of the sleeve is slidably engaged with a support rod fixedly connected to the support plate.

[0014] Furthermore, a spiral groove is provided on the outer side of the transmission ring, a limiting rod is fixed on the outer side of the carrier plate, and one end of the limiting rod is rotatably connected to a limiting column which is slidably engaged with the spiral groove.

[0015] Furthermore, a rotating ring is embedded and fixed in the inner top of the cylinder shell, the transmission shaft includes a transmission shaft rotatably connected to the rotating ring, the transmission shaft includes a transmission cylinder fixedly connected to the third output end of the motor, and the inner side of the transmission cylinder is slidably clamped with a movable shaft fixedly connected to the circular plate.

[0016] Furthermore, a plurality of limit blocks are fixed on the bottom surface of the circular plate in a circular shape at equal angles, a connecting ring is fixed on the top surface of the circular plate, an electric push rod is embedded and fixed on the top of the cylinder shell one, a connecting rod two is fixed on the output end of the electric push rod, and a ring rotatably sleeved with the connecting ring is fixed on one end of the connecting rod two.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Put the gas cylinder between the support plate and the cylinder shell 1, and the motor 2 drives the screw rod to rotate to make the cylinder shell 2 move toward the cylinder shell 1. The cylinder shell 1 and the cylinder shell 2 are spliced ​​into a complete cylinder body and sleeved on the top of the gas cylinder. The semi-bend pipe 1 inside the cylinder shell 1 and the semi-bend pipe 2 inside the cylinder shell 2 are spliced ​​into a complete bend pipe and sleeved on the outside of the gas pipe of the gas cylinder. At this time, the inflation pipe is connected with the gas pipe through the bend pipe, eliminating the need for manual docking and installation of the inflation pipe and the gas pipe during the inflation process;

[0019] The output end of the electric push rod moves down with the collar on the second connecting rod so that the circular plate moves down to cover the top surface of the hand wheel. At the same time, multiple limit blocks on the bottom surface of the circular plate are respectively arranged at the notch positions outside the hand wheel. The output end of the third motor rotates with the transmission shaft so that the circular plate rotates counterclockwise with the hand wheel through multiple limit blocks, thereby opening the valve inside the connecting pipe on the gas cylinder, so that the connecting pipe connects the gas cylinder with the gas transmission pipe, eliminating the need to manually twist the hand wheel to open the valve of the gas cylinder during the inflation process.

[0020] The air inlet pipe is connected to the air intake pipe, and the air intake pipe conveys gas to the air guide pipe through the inflation pipe. The gas flows into the bent pipe through the air guide pipe and is then injected into the gas cylinder through the gas supply pipe and the connecting pipe. As the amount of gas filled in the gas cylinder increases, the overall weight of the gas cylinder increases, and the gas cylinder during the inflation process gradually moves downward on the support plate with the help of its own gravity. During the downward movement, the bent pipe holds the air guide pipe and moves downward synchronously. After the gas cylinder is inflated, the bent pipe moves downward to position B inside the inflation pipe. At this time, the protruding part at the bottom of the inflation pipe blocks the air hole of the air guide pipe, so that the air guide pipe stops supplying gas to the gas cylinder, so that the gas cylinder pipeline filled with gas can be automatically disconnected with the help of the weight of the inflated gas cylinder, eliminating the need to manually observe the inflation amount displayed on the inflation instrument to determine whether to stop inflation. On the basis of the gas cut-off of the external gas tank valve, a structure is provided in which the gas guide pipe is automatically disconnected and gas supply is stopped when the gas cylinder is full of gas, so as to further improve the safety of gas cylinder inflation.

[0021] 2. During the process of inflating the top of the gas cylinder by sealing and clamping the cylinder shell one and the cylinder shell two, the air suction end of the external air pump can be connected to the air suction pipe, and the air pump can be used to suck air into the air suction pipe to make the inside of the cylinder body formed by the cylinder shell one and the cylinder shell two in a negative pressure state. Then the air pump is stopped to pump air, and the maintenance state of the negative pressure environment inside the cylinder body can be observed with the help of a barometer. Because the inside of the gas cylinder is in a high pressure state due to continuous inflation at this time, if there is a leak at the valve seat, connecting pipe, gas transmission pipe and other connecting positions on the top of the gas cylinder, the negative pressure environment inside the cylinder body will be destroyed. Whether the top pipeline position of the gas cylinder is leaking during the inflation process can be judged based on whether the air pressure of the negative pressure environment increases, which is beneficial to improving the safety during the inflation process. If there is a leak at the top of the gas cylinder during the inflation process, the air pump can be used to suck gas into the air suction pipe, so that the leaked gas can be sucked and collected in time to prevent the leaked gas from diffusing into the environment when the cylinder body is opened.

[0022] 3. After the gas cylinder is inflated, the screwing mechanism can be used to automatically tighten the handwheel to close the valve on the gas cylinder, eliminating the need to manually close the valve, and open the solenoid valve inside the L-shaped hole on the connecting rod, so that the elbow and the gas pipe on the gas cylinder are connected to the internal space of the cylinder through the L-shaped hole. The air pump sucks the gas inside the cylinder through the suction pipe, which is convenient for sucking out the small amount of gas remaining in the elbow and the gas pipe on the gas cylinder, preventing the residual gas in the inflation process from leaking after the cylinder is opened.

[0023] 4. A transmission ring is rotated on the outer side of the support plate, and a spiral groove is opened on the outer side of the transmission ring. The end of the limit rod on the carrier plate is rotatably connected to a limit column slidably engaged with the spiral groove. During the inflation process, the gas cylinder moves the support plate downward with the help of its own gravity, and the support plate moves downward with the transmission ring. The limit column drives the transmission ring to rotate through the spiral groove. The transmission ring drives the cleaning brush roller to revolve around the outer side of the gas cylinder. At the same time, the motor drives the cleaning brush roller to rotate, so that the cleaning brush roller can be moved to different positions outside the gas cylinder to clean the gas cylinder, so that the gas cylinder can be automatically cleaned in all directions with the help of the gravity of the gas cylinder during the inflation process, which is conducive to keeping the gas cylinder clean and tidy.

DETAILED DESCRIPTION

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] For example, see Figure 1-11In an embodiment of the present invention, a mobile gas cylinder inflation device includes a carrier plate 100, a support mechanism 200 for placing the gas cylinder is fixed to the bottom surface of the carrier plate 100, the support mechanism 200 includes a telescopic pipe 210 fixedly connected to the carrier plate 100, a support plate 220 is fixed to the top of the telescopic pipe 210, a transmission ring 230 is rotatably provided on the outer side of the support plate 220, a cleaning brush roller 240 for cleaning the gas cylinder is rotatably connected to the top of the transmission ring 230, a cylinder 110 is fixed to one side of the carrier plate 100, a cylinder shell 300 slidably connected to the carrier plate 100 is detachably adsorbed and fixed at the output end of the cylinder 110 through an electromagnet, a motor 2 310 is fixed to both sides of the cylinder shell 300, and a wire is fixed to the output end of the motor 2 310 Rod 311, a cylinder shell 2 400 with the same outer dimensions as the cylinder shell 1 300 is screwed together between the two screw rods 311, a screwing mechanism 500 for automatically screwing the hand wheel on the gas cylinder is arranged at the inner top of the cylinder shell 1 300, the screwing mechanism 500 comprises a motor 3 510 fixedly connected to the cylinder shell 1 300, a transmission shaft 511 is fixedly provided at the output end of the motor 3 510, a circular plate 520 is fixedly provided at the bottom end of the transmission shaft 511, a semi-bend pipe 1 320 and a semi-bend pipe 2 410 with the same outer dimensions are respectively embedded and fixed in the interior of the cylinder shell 1 300 and the cylinder shell 2 400, an air guide tube 321 is connected and fixed at the top of the semi-bend pipe 1 320, and an inflation pipe 600 fixedly connected to the carrier plate 100 is sleeved on the outer side of the air guide tube 321.

[0038] Specifically, the gas cylinder is placed between the support plate 220 and the cylinder shell 1 300, and the motor 2 310 drives the screw rod 311 to rotate so that the two cylinder shells are spliced ​​into a cylinder body and sleeved on the top of the gas cylinder, so that the top pipeline connection position is in a sealed environment during the gas cylinder inflation process, and the cylinder body is placed in a negative pressure state by means of an air pump to pump air into the air extraction pipe 350 on the cylinder body. By observing whether the negative pressure state changes, it is determined whether the gas cylinder is leaking during the inflation process, thereby achieving the effect of safe inflation, and the motor 3 510 drives the transmission shaft 511 to rotate the circular plate 520 and the limit block 521 to rotate the hand wheel, thereby realizing automatic regulation of the opening and closing of the valve on the gas cylinder. Two half-bend pipes are arranged at the bottom of the air pipe 600. When the two cylinder shells are spliced ​​into a cylinder body, the two half-bend pipes will be synchronously spliced ​​into a complete bend pipe and sleeved between the gas supply pipe and the gas guide pipe 321, so that the gas supply pipe on the gas cylinder can be automatically connected with the external inflation pipe 600, eliminating the need for manual pipeline docking. During the inflation process, the cylinder body is moved down synchronously with the gas cylinder with the help of the bend pipe and the gas guide pipe 321 by virtue of the increase in the weight of the gas cylinder. After the gas cylinder is filled with gas, the bend pipe brings the gas guide pipe 321 down to the position of the inside of the inflation pipe 600 to block the gas guide pipe 321, so that the gas cylinder pipeline filled with gas is automatically disconnected by virtue of the weight of the inflated gas cylinder, thereby improving the safety of inflation.

[0039] like Figure 2 and Figure 5As shown, in this embodiment, the top of the inflation tube 600 is connected to and fixed with an air inlet pipe 610, and the outer side of the inflation tube 600 is fixed with a connecting column 620 fixedly connected to the carrier plate 100, the inner tube diameter of the inflation tube 600 is larger than the diameter of the air guide tube 321, and a plurality of ventilation holes 3211 are evenly opened on the top of the air guide tube 321.

[0040] In this embodiment, the air inlet pipe 610 is connected to the pumping gas pipeline of the external gas tank, so as to facilitate the gas delivery to the inflation pipe 600, and then inflate the gas cylinder through the inflation pipe 600. The connecting column 620 is fixed on the carrier plate 100, and the inflation pipe 600 during the inflation process will not move downward as the air guide tube 321 moves downward, so as to facilitate the relative movement of the air guide tube 321 and the inflation pipe 600, and then the vent hole 3211 on the air guide tube 321 is blocked by the protrusion at position B of the inflation pipe 600. The internal tube cavity diameter of the inflation pipe 600 is larger than the diameter of the air guide tube 321, so that during the movement of the air guide tube 321 in the space above the protrusion of the inflation pipe 600, the inflation pipe 600 and the air guide tube 321 are in a connected state.

[0041] like Figure 5 and Figure 8 As shown, in this embodiment, a connecting rod 322 is fixed to the outer side of the half-bend pipe 320 and the half-bend pipe 410, and an L-shaped hole 3221 is provided at one end of the connecting rod 322 at the position of the half-bend pipe 320, and a solenoid valve is installed in series inside the L-shaped hole 3221.

[0042] In this embodiment, the connecting rod 1 322 enables two half-bend pipes 1 320 and half-bend pipe 2 410 with exactly the same structure and size to be firmly fixed on the cylinder shell including the cylinder shell 1 300 and the cylinder shell 2 400. The L-shaped hole 3221 opens the solenoid valve inside it after the inflation is completed, so that the gas remaining in the gas supply pipe and the bent pipe can be sucked to the outside through the exhaust pipe 350. The sides of the half-bend pipe 1 320 and the half-bend pipe 2 410 that abut each other are both sleeved with sealing gaskets, which can improve the sealing performance of the half-bend pipe 1 320 and the half-bend pipe 2 410 after forming a bent pipe. Similarly, the contact surfaces of the two cylinder shells can also be installed with sealing gaskets of the prior art to improve the sealing performance after being spliced ​​into a cylinder body.

[0043] like Fig. 9 As shown, in this embodiment, two fixing seats are fixed on the outer side of the cylinder shell 1 300 and are respectively rotatably connected to the screw rods 311 at corresponding positions, and two transmission seats are fixed on the outer side of the cylinder shell 2 400 and are respectively screwed together with the screw rods 311 at corresponding positions. The top of the cylinder shell 1 300 is connected and fixed with an exhaust pipe 350.

[0044] After the gas is inflated, the motor 310 can reversely drive the screw rod 311 to rotate so that the transmission seat screwed with the screw rod 311 can move the cylinder shell 2 400 toward the cylinder shell 1 300, thereby making the two cylinder shells seal the top of the gas cylinder and inflate it. After the gas is inflated, the motor 310 can reversely drive the screw rod 311 to rotate so that the transmission seat can move the cylinder shell 2 400 away from the cylinder shell 1 300, thereby making it convenient to take out the gas cylinder between the two cylinder shells. The suction pipe 350 is mainly combined with the external suction pump to suck out the residual gas inside the cylinder. Of course, before the gas cylinder is inflated, in order to discharge the small amount of gas remaining in the gas cylinder, the valve of the gas cylinder and the solenoid valve inside the L-shaped hole 3221 can be opened after the gas cylinder is sealed in the two cylinder shells. The air pump can suck out the air inside the cylinder through the suction pipe 350. At this time, the residual gas in the gas cylinder emitted from the inside of the gas cylinder through the gas supply pipe, the bent pipe and the L-shaped hole 3221 will be sucked and cleaned by the suction pipe 350, thereby achieving pre-cleaning of the residual gas inside the gas cylinder.

[0045] like Figure 1-3 As shown, in this embodiment, a clamping block 330 is fixed to the outer side of the cylinder shell 1 300 , a connecting block 331 made of iron material is fixed to the outer side of the clamping block 330 , and a sliding groove 130 slidably engaged with the clamping block 330 is provided on the outer side of the carrier plate 100 .

[0046] In this embodiment, the block 330 on the outside of the cylinder shell 1 300 can slide inside the slide groove 130, so that the cylinder shell 2 400 and the cylinder shell 1 300 can stably move up and down along the carrier 100. In the initial state, the electromagnet at the output end of the cylinder 110 adsorbs and fixes the connecting block 331, and the output end of the cylinder 110 is extended to allow the connecting block 331 to move the cylinder shell 1 300 and the cylinder shell 2 400 to the top of the carrier 100, providing sufficient space for placing the gas cylinder between the support plate 220 and the cylinder shell 1 300. During the inflation process, in order to enable the cylinder shell to move downward synchronously with the gas cylinder, the electromagnet can be powered off and no longer adsorbed and fixed to the connecting block 331. At this time, the cylinder shell is sleeved and fixed on the top of the gas cylinder. In order to prevent the output end of the cylinder 110 from affecting the downward movement of the connecting block 331, the output end of the cylinder 110 can be retracted away from the connecting block 331.

[0047] like Figure 4 As shown, in this embodiment, the telescopic tube 210 includes a sleeve fixedly connected to the carrier plate 100, and the inner sliding clamp of the sleeve is engaged with a support rod fixedly connected to the support plate 220. When the support plate 220 moves downward, the support rod slides into the sleeve, and when the support plate 220 moves upward, the support rod slides out from the sleeve, thereby enabling the support plate 220 to move up and down stably.

[0048] like Figure 6 and Figure 7As shown, in this embodiment, a rotating ring 340 is embedded and fixed in the inner top of the cylinder shell 300, and the transmission shaft 511 includes a transmission shaft 511 rotatably connected to the rotating ring 340, and the transmission shaft 511 includes a transmission cylinder 5111 fixedly connected to the output end of the motor three 510, and the inner side of the transmission cylinder 5111 is slidably clamped with a movable shaft 5112 fixedly connected to the circular plate 520.

[0049] In this embodiment, the rotating ring 340 enables the transmission shaft 511 to rotate stably on the cylinder shell, a key slot 5113 is provided on the outer side of the movable shaft 5112, and a key block slidingly engaged with the key slot 5113 is fixed on the inner side of the transmission cylinder 5111, so that the movable shaft 5112 can move up and down along the transmission cylinder 5111 to adjust the overall length of the transmission shaft 511, thereby satisfying the movement of the circular plate 520 to the top surface of the handwheel or leaving the handwheel, and at the same time, the movable shaft 5112 can rotate as the transmission cylinder 5111 rotates.

[0050] like Figure 6 and Figure 7 As shown, in this embodiment, the bottom surface of the circular plate 520 is annularly fixed with multiple limit blocks 521 at equal angles, the top surface of the circular plate 520 is fixed with a connecting ring 522, and an electric push rod 530 is embedded and fixed at the top of the cylinder shell 300. A connecting rod 2 531 is fixed to the output end of the electric push rod 530, and a ring that is rotatably sleeved with the connecting ring 522 is fixed to one end of the connecting rod 2 531.

[0051] In this embodiment, the limit block 521 is inserted into the notch on the side of the handwheel, and then as the circular plate 520 rotates, the limit block 521 screws the handwheel, and the electric push rod 530 moves up and down with the ring through the connecting rod 2 531, and then the ring moves up and down with the connecting ring 522 to adjust the position, which is convenient for adjusting the position of the circular plate 520. The ring is rotatably connected to the connecting ring 522, so that when the circular plate 520 rotates with the connecting ring 522, the ring will not rotate with the connecting ring 522.

[0052] During specific implementation, in the initial state, refer to the instructions Figure 1 and Figure 2 The two cylinder shells (including cylinder shell 1 300 and cylinder shell 2 400) are separately arranged at the top of the carrier plate 100. The output end of the cylinder 110 is supported by a fixed connection block 331 to keep the cylinder shell in a fixed position. When inflating, the checked gas cylinder to be inflated is placed between the cylinder shell 1 300 and the support plate 220 (refer to the instructions). Figure 3), the suction cup 222 on the support plate 220 absorbs and fixes the gas cylinder from the bottom of the gas cylinder, the electric push rod 530 moves the circular plate 520 downward, so that multiple limit blocks 521 are sleeved on the outer notch of the hand wheel, and then the motor 2 310 drives the screw rod 311 to rotate to make the cylinder shell 2 400 move and stick to the cylinder shell 1 300, and at the same time, the semi-bend pipe 2 410 inside the cylinder shell 2 400 moves and sticks to the semi-bend pipe 1 320 inside the cylinder shell 1 300, the two cylinder shells constitute a cylinder body sleeved on the top of the gas cylinder, the two semi-bend pipes are spliced ​​into a bend pipe sleeved on the outside of the gas pipe on the gas cylinder, the motor 3 510 drives the circular plate 520 to rotate with the limit block 521 to rotate the hand wheel to open the valve on the gas cylinder, so that the connecting pipe on the gas cylinder is connected to the gas pipe, and the pipeline of the external pumped gas (the specific gas type is not limited, it can be natural gas or some industrial gas) is directed to the air inlet pipe 610 The gas is then delivered through the inflation tube 600 to the gas guide tube 321, and then from the gas guide tube 321 to the gas delivery tube through the bent tube, and finally enters the gas cylinder through the connecting tube. As the gas cylinder is continuously inflated, the weight of the gas cylinder itself increases, and the gas cylinder will move downward with the support plate 220. During the downward movement, the cylinder body and the bent tube move downward synchronously with the gas guide tube 321. After the gas cylinder is inflated, the bent tube moves downward with the gas guide tube 321 to position B inside the inflation tube 600. At this time, the protruding part at the bottom of the inflation tube 600 blocks the air hole 3211 of the gas guide tube 321, so that the gas guide tube 321 stops delivering gas to the gas cylinder, and then the screwing mechanism 500 rotates the handwheel in the opposite direction to tighten the handwheel, so that the valve on the gas cylinder is closed, and then the screw rod 311 is driven in the opposite direction to rotate to separate the two cylinder shells, and the electric push rod 530 moves the circular plate 520 upward to take out the inflated gas cylinder.

[0053] Embodiment 2, based on embodiment 1, is for supporting, fixing and cleaning the gas cylinder during the inflation process.

[0054] like Figure 4 As shown, in this embodiment, a return spring 221 is fixed between the bottom surface of the support plate 220 and the top surface of the carrier plate 100 , a suction cup 222 is embedded and fixed on the top surface of the support plate 220 , and the return spring 221 is sleeved on the outside of the telescopic tube 210 .

[0055] In this embodiment, during the inflation process, the gas cylinder moves downward with the support plate 220 to compress the return spring 221. After the gas cylinder is taken out at a later time, the support plate 220 can be returned to the initial position for standby use under the elastic force of the return spring 221. The suction cup 222 helps the support plate 220 to firmly support and fix the gas cylinder from the bottom of the gas cylinder.

[0056] like Figure 1 and Figure 4 As shown, in this embodiment, a spiral groove 231 is formed on the outer side of the transmission ring 230 , a limiting rod 120 is fixed on the outer side of the carrier plate 100 , and one end of the limiting rod 120 is rotatably connected to a limiting column 121 that is slidably engaged with the spiral groove 231 .

[0057] In this embodiment, when the support plate 220 moves downward with the transmission ring 230, the limiting column 121 at the end of the limiting rod 120 will use the spiral groove 231 to cause the downwardly moving transmission ring 230 to rotate synchronously. A motor 232 for driving the cleaning brush roller 240 to rotate is embedded in the top of the transmission ring 230. The transmission ring 230 rotates around the gas cylinder to transfer the cleaning brush roller 240 to different positions outside the gas cylinder. The motor 232 drives the cleaning brush roller 240 to rotate to clean the dust and impurities on the outside of the gas cylinder, thereby ensuring that the gas cylinder is clean and tidy.
