Abstract
Description
Technical Field
[0001] This utility model belongs to the field of inspection bracket technology and relates to a highly adaptable gas cylinder inspection bracket. Background Technology
[0002] Gas cylinder inspection brackets are professional auxiliary equipment used in the gas cylinder inspection process. They are mainly used to stably support the gas cylinders to be inspected, making it easier for inspectors to carry out operations such as appearance inspection, internal cleaning, and pressure testing efficiently.
[0003] A Chinese utility model patent with publication number CN214332317U discloses a gas cylinder inspection bracket, comprising a fixed base, a rotating base, a support, and rollers. The upper part of the fixed base is fixedly connected to a ball bearing turntable. The rotating base is rotatably connected to the fixed base via the ball bearing turntable. The support has positioning holes for supporting gas cylinders of different diameters. Both ends of the rollers are fixed to the support through the positioning holes and rotatably connected to the support.
[0004] The existing technology has the following technical defects:
[0005] Traditional support brackets are limited by their fixed shape and can only fit a single type of gas cylinder, making it difficult to meet diverse testing needs. Their support structure is mostly a slot or bracket with fixed spacing. When faced with gas cylinders of different diameters and heights, such as small-volume oxygen cylinders and large-sized liquefied gas cylinders, their adaptability is poor. Due to the lack of an adjustable mechanism, problems such as unstable support, suspension, or excessive local stress may occur. This not only makes the testing operation inconvenient, but may also lead to the risk of slippage due to insecure fixing, and may even cause wear on the surface of the gas cylinder or deviation in the test data. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a highly adaptable gas cylinder inspection bracket.
[0007] The highly adaptable gas cylinder inspection bracket of this utility model includes a support frame, on which a first bidirectional electric push rod is provided. The moving parts at both ends of the first bidirectional electric push rod are respectively hinged to two rotating rods, which are staggered. The rotating rods at corresponding positions at both ends of the first bidirectional electric push rod are connected to the same elastic telescopic rod.
[0008] The elastic telescopic rod includes a fixed tube, with sliding rods slidably connected to both ends of the fixed tube. A spring is installed inside the fixed tube, located between the two sliding rods. A socket adapted to the rotating rod is provided at one end of the outer side of the sliding rod.
[0009] The rotating rod is equipped with a first driving component that is adapted to the elastic telescopic rod.
[0010] The first driving component includes a motor fixedly installed inside the rotating rod. The output end of the motor passes through the rotating rod and is fixedly connected to a first gear. The first gear meshes with a second gear fixedly connected to a socket.
[0011] The upper part of the support frame is also provided with a second driving component that is adapted to the rotating rod.
[0012] The second driving component includes a guide frame that is fixedly connected to both ends of the first bidirectional electric push rod. The guide frame is slidably connected to the support frame. The second bidirectional electric push rod is fixedly installed on the guide frame. Each push rod has a groove at its bottom, and a slider that is fixedly connected to the second bidirectional electric push rod is slidably connected in the groove.
[0013] Working process or working principle:
[0014] Regarding cylinder length adaptation, when it is necessary to inspect cylinders of different lengths, the operator drives the first bidirectional electric actuator through the control system. The first bidirectional electric actuator serves as the core power source. Its moving part extends and retracts smoothly along a fixed track under the drive of electric energy. The two rotating rods installed at the outer end of the moving part change their relative distance as the moving part extends and retracts, thereby driving the elastic telescopic rod to perform synchronous extension and retraction. The elastic telescopic rod ensures that cylinders of different lengths can obtain stable and safe support on the bracket.
[0015] Regarding cylinder diameter adaptation, the two rotating rods are staggered. When supporting cylinders of different diameters is required, the operator can drive the rotating rods to rotate. The rotation of the rotating rods will change the angle and position of the elastic telescopic rod in contact with the cylinder. The staggered structure allows the elastic telescopic rod to adapt to the circumferential surface of the cylinder at different opening and closing degrees. As the rotating rods rotate, the elastic telescopic rod will automatically adjust its fit with the outer wall of the cylinder according to the cylinder diameter. When the cylinder diameter is small, the elastic telescopic rod retracts inward to tightly wrap the cylinder; when the cylinder diameter is large, the elastic telescopic rod opens outward to maintain stable support.
[0016] Compared with the prior art, the beneficial effects of this utility model are:
[0017] This invention enables the bracket to accurately adapt to various sizes of gas cylinders. Regardless of the cylinder diameter, it ensures that the elastic telescopic rod is evenly stressed, avoiding localized stress concentration that could damage the cylinder. At the same time, it provides stable support, ensuring the safe and efficient conduct of gas cylinder inspection work. This solves the problem that traditional brackets, due to their fixed shape, cannot adapt to gas cylinders of different sizes. Attached Figure Description

Detailed Implementation
[0023] Example 1
[0024] like Figures 1-4 As shown, the highly adaptable gas cylinder inspection bracket of this utility model includes a support frame 1, on which a first bidirectional electric push rod 2 is provided. The moving parts at both ends of the first bidirectional electric push rod 2 are respectively hinged to two rotating rods 3, which are staggered. The same elastic telescopic rod 4 is connected to the rotating rods 3 at corresponding positions at both ends of the first bidirectional electric push rod 2.
[0025] The aforementioned highly adaptable gas cylinder inspection bracket revolves around a two-dimensional adaptive adjustment. Regarding cylinder length adaptation, when it is necessary to inspect gas cylinders of different lengths, the operator drives the first bidirectional electric actuator 2 through the control system. The first bidirectional electric actuator 2 serves as the core power source, and its moving part extends and retracts smoothly along a fixed track under the drive of electric energy. The two rotating rods 3, which are respectively installed at the outer end of the moving part, change their relative distance as the moving part extends and retracts, thereby driving the elastic telescopic rod 4 to perform synchronous extension and retraction. The elastic telescopic rod 4 ensures that gas cylinders of different lengths can obtain stable and safe support on the bracket.
[0026] Regarding cylinder diameter adaptation, the two rotating rods 3 are staggered. When supporting cylinders of different diameters, the operator can drive the rotating rods 3 to rotate. The rotation of the rotating rods 3 changes the angle and position of the elastic telescopic rod 4 in contact with the cylinder. The staggered structure allows the elastic telescopic rod 4 to adapt to the circumferential surface of the cylinder at different opening and closing degrees. As the rotating rods 3 rotate, the elastic telescopic rod 4 automatically adjusts its fit to the outer wall of the cylinder according to the cylinder diameter. When the cylinder diameter is small, the elastic telescopic rod 4 retracts inward to tightly wrap the cylinder; when the cylinder diameter is large, the elastic telescopic rod 4 opens outward to maintain stable support. This design allows the bracket to accurately adapt to various cylinder specifications. No matter how the cylinder diameter changes, it ensures that the elastic telescopic rod 4 is evenly stressed, avoiding local stress concentration that could damage the cylinder. At the same time, it provides stable support, ensuring the safe and efficient conduct of cylinder inspection work, and solving the problem that traditional brackets cannot adapt to cylinders of different sizes due to their fixed shape.
[0027] In this embodiment, the elastic telescopic rod 4 includes a fixed tube 8, with slide rods 10 slidably connected to both ends of the fixed tube 8. A spring 9 is installed inside the fixed tube 8, located between the two slide rods 10. A socket 11 adapted to the rotating rod 3 is provided at one end of the outer side of the slide rod 10. The elastic telescopic rod 4 can achieve synchronous movement and flexible replacement. Its core component, the spring 9, is installed inside the fixed tube 8. When the first bidirectional electric push rod 2 moves and drives the rotating rod 3 to move, the socket 11 inserted into the inner side of the rotating rod 3 will be subjected to force. The external force is transmitted to the spring 9 through the slide rod 10. The spring 9 is compressed or stretched to produce deformation, driving the slide rod 10. The elastic telescopic rod 4 slides within the fixed tube 8, thus enabling its extension and retraction. This ensures synchronous movement when the first bidirectional electric push rod 2 moves, accommodating the support requirements of gas cylinders of different lengths. The socket 11 and the inner side of the rotating rod 3 are connected by a plug-in method. This connection method is simple and convenient. Users can quickly disassemble and install the elastic telescopic rod 4 by simply plugging and unplugging it. By designing sockets 11 and fixed tubes 8 with different diameter specifications, it can be adapted to various gas cylinder diameters. When facing different gas cylinder testing needs, users can easily replace the elastic telescopic rod 4 with the corresponding size, greatly improving the versatility and adaptability of the bracket.
[0028] In this invention, the rotating rod 3 is equipped with a first driving component 5 adapted to the elastic telescopic rod 4. The first driving component 5 includes a motor 12 fixedly installed inside the rotating rod 3. The output end of the motor 12 passes through the rotating rod 3 and is fixedly connected to a first gear 13. The first gear 13 meshes with a second gear 14 fixedly connected to a socket 11. When it is necessary to perform rotation detection on the gas cylinder, the operator starts the motor 12 fixedly installed inside the rotating rod 3. The motor 12 outputs torque as a power source, and its output end drives the first gear 13 to rotate at high speed. Since the first gear 13 and the second gear 14 mesh with each other, according to the gear transmission principle, the rotation of the first gear 13 will precisely transmit the power. The signal is transmitted to the second gear 14, causing the second gear 14 to rotate at a corresponding speed and direction. The second gear 14 is fixedly installed on one of the sockets 11, which is connected to the slide bar 10 of the elastic telescopic rod 4. Therefore, the rotation of the second gear 14 can drive the socket 11, the slide bar 10, and the entire elastic telescopic rod 4 to rotate synchronously. When the elastic telescopic rod 4 rotates, it will drive the gas cylinder on it to rotate, so that the inspectors can perform appearance inspection and defect detection on the surface of the gas cylinder from all angles without manually flipping the gas cylinder. This effectively improves the efficiency and accuracy of gas cylinder inspection and provides reliable automated support for gas cylinder safety inspection.
[0029] In this invention, the upper part of the support frame 1 is further provided with a second driving component 6 adapted to the rotating rod 3. The second driving component 6 includes a guide frame 15 fixedly connected to both ends of the first bidirectional electric push rod 2. The guide frame 15 is slidably connected to the support frame 1, and a second bidirectional electric push rod 16 is fixedly installed on the guide frame 15. Each rotating rod 3 has a groove 7 at its bottom, and a slider 17 fixedly connected to the second bidirectional electric push rod 16 is slidably connected in the groove 7. The core of the second driving component 6 lies in the coordinated operation of the two guide frames 15 and the second bidirectional electric push rod 16. The guide frame 15 is fixed on both sides of the first bidirectional electric push rod 2, and its lower part slides against the upper part of the support frame 1, providing stable guidance and support for the entire adjustment process. The second bidirectional electric push rod 16 fixedly installed inside each guide frame 15 serves as a power source, which can accurately control the output direction and displacement. The groove 7 on the rotating rod 3 and the slider 17 form a sliding connection structure, and the slider 17 can slide flexibly in the groove 7. The output ends of the second bidirectional electric actuators 16 are fixedly connected to the sliders 17 in the corresponding grooves 7 of the rotating rods 3. When it is necessary to adjust the distance between the two elastic telescopic rods 4, the operator starts the second bidirectional electric actuators 16. The output ends of the electric actuators push or pull the sliders 17. While the sliders 17 move in the grooves 7, they drive the rotating rods 3 to rotate around the rotation connection point between them and the moving part of the first bidirectional electric actuator 2. Since the two rotating rods 3 are staggered, as the second bidirectional electric actuators 16 extend and retract, the two rotating rods 3 will open and close in opposite directions, thereby driving the elastic telescopic rods 4 connected to the inner side of the rotating rods 3 to change the distance. Whether it is necessary to reduce the distance to fit small-diameter gas cylinders or increase the distance to support large-diameter gas cylinders, the second bidirectional electric actuators 16 can achieve precise opening and closing adjustment by precisely controlling the extension and retraction of the staggered rotating rods 3, thereby flexibly adjusting the distance between the two elastic telescopic rods 4, ensuring that gas cylinders of different diameters can obtain stable and appropriate support on the bracket.
