Abstract
Description
Technical Field
[0001] This application relates to the field of gas cylinder manufacturing, and in particular to a gas cylinder clamping device. Background Technology
[0002] "Gas cylinder" generally refers to a mobile pressure vessel used for storing and transporting compressed gases, liquefied gases, or dissolved gases, and is widely used in industries, medical fields, laboratories, and fire protection. A clamping device is used to clamp the gas cylinder to facilitate inspection or cleaning.
[0003] The clamping device typically consists of a body, cylinder, pressure plate, gasket, and positioning seat. The positioning seat is fixed to the lower end of the body and is used for temporary positioning of the cylinder. The cylinder is fixedly connected to the upper end of the body, and the lower end of the piston rod is fixedly connected to the pressure plate. The gasket is fixedly installed on the lower side of the pressure plate and is used to reduce damage to the surface of the gas cylinder caused by the pressure plate. When the cylinder drives the pressure plate to fall until the gasket is pressed against the outer wall of the gas cylinder, it can fix the gas cylinder on the positioning seat and prevent the gas cylinder from being misaligned during inspection or cleaning.
[0004] In the prior art, since the gasket comes into frequent contact with the gas cylinder, it may become damaged after a long period of use. This can cause damage to the outer wall of the gas cylinder during the compression process or affect the gas cylinder's fixing effect. Furthermore, it is not convenient to quickly replace the gasket, which in turn affects the compression detection or cleaning efficiency of the gas cylinder. Utility Model Content
[0005] To facilitate the replacement of the protective pad, this application provides a gas cylinder clamping device.
[0006] The gas cylinder clamping device provided in this application adopts the following technical solution:
[0007] A gas cylinder pressing device includes a body, a positioning frame mounted on the upper end of the body, a drive push rod fixedly mounted on the upper end of the positioning frame, a plurality of positioning seats mounted on the lower end of the body, a shock-absorbing pad fixedly connected to the upper side of the positioning seat, an auxiliary roller provided between every two positioning seats, a pressure plate mounted on the lower end of the piston rod of the drive push rod, a connector connected to the lower side of the pressure plate, limiting members for restricting the connector mounted on both ends of the pressure plate, a gasket connected to the lower side of the connector, an insertion rod fixedly connected to both ends of the connector, and slots for inserting the insertion rods opened at both ends of the pressure plate.
[0008] By adopting the above technical solution, firstly, the gas cylinder can be effectively compressed and fixed, while preventing the gas cylinder from shaking or misaligning during the compression process; secondly, by adjusting the position of the pressure plate and connecting parts, it can adapt to gas cylinders of different sizes and shapes; thirdly, the setting of the limiting parts facilitates the replacement of connecting parts and gaskets, reducing the time and effort spent on replacing gaskets; and fourthly, the setting of the auxiliary roller can prevent the gas cylinder from contacting the shock-absorbing pad when placed, thereby improving the placement efficiency of the gas cylinder.
[0009] Optionally, a support frame for preventing the gas cylinder from rolling is fixedly connected to the middle of each positioning seat, and a protective pad is fixedly connected to the upper side of each support frame.
[0010] By adopting the above technical solution, it is possible to prevent the gas cylinder from rolling during the compression process, thereby ensuring the processing or testing effect of the gas cylinder. The protective pad can also prevent the gas cylinder surface from directly contacting the support frame and causing wear, thus protecting the gas cylinder surface from damage.
[0011] Optionally, the limiting member includes a push plate, multiple movable blocks, and multiple positioning pins. The pressure plate has grooves at both ends for sliding of the multiple movable blocks. The push plate is fixedly connected to the upper end of the multiple movable blocks and its lower side is slidably connected to the upper side of the pressure plate. The multiple positioning pins are fixedly connected to one side of the movable blocks.
[0012] By adopting the above technical solution, the push plate pushes the movable block to move, which in turn drives the positioning pin to move, thus achieving precise positioning of the connecting parts. This ensures that the pressure plate can stably act on the connecting parts during the pressing process, allowing operators to easily adjust the limiting parts by simply pushing or pulling the push plate, making the operation convenient and quick.
[0013] Optionally, each of the slides has a through hole communicating with the slot on one side, and multiple positioning pins are respectively inserted through the inner wall of the through hole. Each of the inserts has a positioning groove on one side for inserting one end of the positioning pin.
[0014] By adopting the above technical solution, the precise positioning and stable connection between the connector and the pressure plate can be guaranteed. During the pressing process, displacement of the connector can be prevented, thereby achieving reliable pressing of the gas cylinder.
[0015] Optionally, each of the movable blocks is fixedly connected to a limit rod on the side opposite to the positioning pin, and the inner wall of the pressure plate is provided with a limit groove for the limit rod to slide.
[0016] By adopting the above technical solution, the sliding direction of the movable block is restricted, so that it can only slide along a predetermined trajectory in the slide groove, avoiding the movable block from deviating or shaking during the sliding process, and ensuring that the positioning pin can accurately pass through the through hole and be inserted into the positioning groove.
[0017] Optionally, a return spring is sleeved on the outer side of each of the limiting rods, and the return springs abut against the inner wall of the movable block and the slide groove respectively.
[0018] By adopting the above technical solution, the elastic force of the reset spring allows the limiting component to automatically return to its initial state after each use, thereby ensuring that the structure remains in its original position without external interference, thus improving the stability of the connection between structures.
[0019] Optionally, each of the push plates has a shielding plate fixedly connected to both ends for covering the groove.
[0020] By adopting the above technical solution, dust, impurities and other contaminants are effectively prevented from entering the slide groove, thus avoiding the obstruction of the sliding block by impurities and ensuring the normal operation of the limiting component.
[0021] Optionally, each of the auxiliary rollers is rotatably connected to a support rod at both ends, and a movable plate is fixedly connected to the lower end of the multiple support rods. Multiple electric push rods fixedly connected to the machine body are fixedly connected to both ends of the movable plate for driving the movable plate to move up and down.
[0022] By adopting the above technical solution, the position of the auxiliary roller can be flexibly adjusted according to the height of the gas cylinder and the clamping requirements, avoiding the situation where the gas cylinder cannot be clamped due to the auxiliary roller, thereby ensuring the clamping effect of the gas cylinder.
[0023] In summary, this application has the following beneficial effects:
[0024] 1. This application can ensure a stable connection between the connector and the pressure plate, prevent the gas cylinder from shaking or misaligning during the pressing process, and facilitate the replacement of the connector, avoiding damage to the gas cylinder surface caused by the gasket.
[0025] 2. This application can flexibly adjust the position of the auxiliary roller according to the height of the gas cylinder and the compression requirements through an electric push rod, thereby reducing the consumption of air force, improving the placement efficiency of the gas cylinder, and avoiding the situation where the gas cylinder cannot be compressed due to improper position of the auxiliary roller.

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0034] This application discloses a gas cylinder clamping device.
[0035] Reference Figure 1 , Figure 2 The gas cylinder clamping device includes a body 1, which consists of a metal frame and a drive box. A positioning frame 2 is fixedly installed on the upper end of the body 1. The positioning frame 2 consists of two connecting rods and a crossbeam. The two ends of the connecting rods are fixedly connected to the crossbeam of the positioning frame 2 and the body 1 by fastening bolts to ensure the stability of the positioning frame 2. A drive push rod 3 is fixedly installed on the upper end of the crossbeam of the positioning frame 2, with its piston rod passing through the middle of the crossbeam. A pressure plate 6 is fixedly installed on the lower end of the piston rod of the drive push rod 3. A connecting piece 8 is connected to the lower side of the pressure plate 6. Limiting pieces 7 are installed at both ends of the pressure plate 6 to restrict the connecting piece 8, fixing it to the lower side of the pressure plate 6. A gasket 9 is fixedly connected to the lower side of the connecting piece 8. Multiple positioning seats 4 arranged in an array are fixedly installed on the lower end of the body 1 for positioning and placing the gas cylinders. Each positioning seat 4 has a shock-absorbing pad 41 fixedly connected to its upper side. The shock-absorbing pad 41 is used to prevent the gas cylinder from being damaged or scratched when it comes into contact with the positioning seat 4. An auxiliary roller 10 is provided between every two positioning seats 4. The auxiliary roller 10 is used to assist in the placement of the gas cylinder and improve the convenience of placing the gas cylinder.
[0036] In use, first, after laying the gas cylinder down, place one end on the auxiliary roller 10. With the help of the auxiliary roller 10, the gas cylinder can be easily pushed onto the upper side of multiple positioning seats 4. Then, the control cabinet of the machine body 1 controls the drive push rod 3 to operate, and uses its piston rod to push the pressure plate 6 and connecting piece 8 down until the pad 9 is pressed against the upper side of the gas cylinder, pressing and fixing the gas cylinder between multiple positioning seats 4, thus facilitating the cleaning or inspection of the gas cylinder.
[0037] Reference Figure 2 , Figure 3 Each positioning seat 4 has a support frame 5 fixedly connected to its upper side. The support frame 5 is an M-shaped bracket used to prevent the gas cylinder from rolling during the compression process. Each support frame 5 has a protective pad 51 fixedly connected to its upper end to prevent the gas cylinder from sliding accidentally, thereby further improving the compression effect of the gas cylinder.
[0038] Reference Figure 2 , Figure 3 Multiple positioning seats 4 have movable plates 12 on their lower sides. Electric push rods 13 are fixedly connected to both ends of each movable plate 12. Each electric push rod 13 is fixedly connected to the machine body 1. The electric push rods 13 are used to drive the movable plate 12 to move up and down under the positioning seats 4. Multiple inclined support rods 11 are fixedly connected to the upper end of the movable plate 12, and auxiliary rollers 10 are rotatably connected between two support rods 11, so that every two adjacent auxiliary rollers 10 are arranged in a V-shape, which can accommodate gas cylinders of different sizes and improve the placement efficiency of gas cylinders.
[0039] In use, the extension or retraction of the piston rod of the electric push rod 13 can drive the movable plate 12 to move downward or upward, thereby causing the auxiliary roller 10 to be lower or higher than the support frame 5. When the auxiliary roller 10 is higher than the support frame 5, the gas cylinder can be easily placed on the upper side of multiple support frames 5. When the auxiliary roller 10 is lower than the support frame 5, the gas cylinder can be stably connected to the protective pad 51 on the support frame 5, which can ensure the compression effect on the gas cylinder.
[0040] Reference Figure 3 , Figure 5 The connector 8 is a metal plate, but in other embodiments it can also be a plastic plate or other materials. Both ends of the connector 8 near the pressure plate 6 are fixedly connected to insert rods 81. Both ends of the pressure plate 6 have slots 61 for inserting the insert rods 81. The connection between the insert rods 81 and the slots 61 improves the ease of connection between the connector 8 and the pressure plate 6.
[0041] Reference Figure 4 , Figure 5 and Figure 6The limiting component 7 includes a push plate 71 slidably connected to the upper side of the pressure plate 6, two movable blocks 72 fixedly connected to one side of the push plate 71, and a positioning pin 73 fixedly connected to one side of the movable blocks 72. The pressure plate 6 has grooves 62 at both ends for the two movable blocks 72 to slide. Pushing the push plate 71 causes the movable blocks 72 to slide along the inner wall of the grooves 62. Each groove 62 has a through hole 621 communicating with the slot 61 on one side. The two positioning pins 73 pass through the inner wall of the through hole 621. Each insertion rod 81 has a positioning groove 82 on one side for inserting one end of the positioning pin 73. When one end of the positioning pin 73 passes through the through hole 621 and inserts into the positioning groove 82, it fixes the insertion rod 81 to the inner wall of the slot 61, ensuring the stability of the connection between the connector 8 and the pressure plate 6.
[0042] Reference Figure 4 , Figure 5 and Figure 6 Each movable block 72 has a limiting rod 74 fixedly connected to the side opposite to the positioning pin 73. The inner wall of the pressure plate 6 has a limiting groove 63 for the sliding of the limiting rod 74. The limiting groove 63 communicates with the slide groove 62, and the sliding of the limiting rod 74 inside the limiting groove 63 is used to prevent the movable block 72 from being misaligned during the sliding process. A return spring 75 is sleeved on the outer side of each limiting rod 74. The return spring 75 abuts against the inner wall of the movable block 72 and the slide groove 62 respectively. The elastic force of the return spring 75 is used to automatically drive the limiting member 7 back to its original position. Each push plate 71 has a shielding plate 76 fixedly connected to both ends to cover the slide groove 62. The shielding plate 76 is used to reduce dust and other impurities falling into the inner wall of the slide groove 62, thereby ensuring the sliding effect of the movable block 72.
[0043] In use, pushing the push plate 71 causes the movable block 72 to slide along the inner wall of the slide groove 62. At this time, the limiting rod 74 slides within the limiting groove 63, and the return spring 75 retracts until one end of the positioning pin 73 disengages from the slot 61. Then, the movable connector 8 fully inserts the insertion rod 81 into the slot 61. Next, the push plate 71 is released, and the elastic force of the return spring 75 pushes the movable block 72, causing the positioning pin 73 to insert into the positioning groove 82, thus fixing the insertion rod 81 within the slot 61, thereby completing the installation of the gasket 9. The gasket 9 can be disassembled by reversing the above steps.
[0044] The operating principle of the gas cylinder clamping device in this application embodiment is as follows:
[0045] When in use, the first step is to start the electric push rod 13 to retract and control the movable plate 12 to move upward until the auxiliary roller 10 is higher than the support frame 5. At this time, place the gas cylinder on the auxiliary roller 10 and push the gas cylinder to move on the auxiliary roller 10 to move it to the upper side of the multiple positioning seats 4. Then control the electric push rod 13 to push the movable plate 12 down until it drives the gas cylinder to fall on the upper side of the multiple support frames 5.
[0046] Step 2: The control cabinet of the machine body 1 controls the drive rod 3 to move, pushing the pressure plate 6, the connecting piece 8 and the gasket 9 to fall down until the gasket 9 is tightly attached to the outside of the gas cylinder, pressing and fixing the gas cylinder, so as to facilitate the inspection or cleaning of the gas cylinder.
[0047] When the gasket 9 needs to be replaced, push the push plate 71 to move the movable block 72 to slide on the inner wall of the slide groove 62 and the limiting rod 74 to slide in the limiting groove 63 until one end of the positioning pin 73 is disengaged from the positioning groove 82. At this time, pull the connector 8 to move the insertion rod 81 out of the slot 61. Then align the connector 8 with the new gasket 9 with the pressure plate 6 and insert the insertion rod 81 into the slot 61 again. Subsequently, release the push plate 71 and use the elastic force of the return spring 75 to push the movable block 72 to slide on the inner wall of the slide until one end of the positioning pin 73 is inserted into the positioning groove 82 of the insertion rod 81, thus locking the insertion rod 81 and fixing the new gasket 9 to the underside of the pressure plate 6.
[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
