Description

Technical Field

[0001] This utility model relates to the field of safety protection device technology, and in particular to a safety protection device for filling gas cylinders. Background Technology

[0002] Gas cylinder filling is a common operation in industrial production, medical, chemical and other fields, used to fill gas cylinders for subsequent use. The traditional gas cylinder filling process is usually completed manually or by simple mechanical devices. After the operator connects the gas cylinder to the filling pipe, he starts the filling equipment to fill it.

[0003] However, in actual operation, during the filling process of the gas cylinder, the filling pipe connects the gas source and the gas cylinder. Its interior is subjected to the impact of high-pressure gas. The filling pipe may swing during filling, which may cause injury to the operator. Utility Model Content

[0004] To address the problem that the filling hose may swing during the filling process of gas cylinders, potentially causing injury to operators, this utility model provides a safety protection device for gas cylinder filling.

[0005] To solve the above problems, the present invention adopts the following technical solution:

[0006] An embodiment of this utility model provides a safety protection device for gas cylinder filling, comprising:

[0007] An inflation device, the inflation device including an inflation tube for filling gas cylinders;

[0008] A protective frame, which has a protected state and a disarmed state, and the protective frame is provided with railings at intervals, with two adjacent railings forming a space for placing gas cylinders;

[0009] A first vertical driving device is used to drive the protective frame to move in the vertical direction. When the protective frame moves in the vertical direction to allow the inflation pipe and gas cylinder to enter the gas cylinder placement space, the protective frame is in a protective state; when the protective frame moves away from the inflation pipe and gas cylinder, the protective frame is in a disarmed state.

[0010] According to some embodiments of the present invention, the inflation device includes a second vertical drive device for driving the inflation tube to move in a vertical direction.

[0011] According to some embodiments of the present invention, the inflation device further includes a mounting bracket for fixing the inflation tube, and the second vertical drive device is connected to the mounting bracket.

[0012] According to some embodiments of the present invention, the bottom of the mounting frame is provided with a collision-resistant block, which can abut against the railing when the mounting frame moves in the vertical direction.

[0013] According to some embodiments of the present invention, a safety protection device for filling gas cylinders further includes an outer frame, which surrounds the outside of the protective frame.

[0014] According to some embodiments of the present invention, the protective frame and the outer frame are slidably connected in the vertical direction.

[0015] According to some embodiments of the present invention, the first vertical driving device includes a driver, a chain, and a sprocket meshing with the chain. The driver is disposed on the outer frame. One end of the chain is connected to the outer frame, and the other end is connected to the protective frame. The sprocket is connected to the driver, and the driver is used to drive the sprocket to move in the vertical direction.

[0016] According to some embodiments of the present invention, the inflation device further includes a safety lock, which is connected to the inflation tube.

[0017] According to some embodiments of the present invention, the inflation tube includes an inflation connector, and the safety lock is connected to the inflation connector.

[0018] This utility model has at least the following beneficial effects: by setting up a protective frame, the gas cylinder is confined within the gas cylinder placement space.

[0025] This invention provides the following description with reference to the accompanying drawings to aid in a comprehensive understanding of the various embodiments of the invention as defined by the claims and their equivalents. The description includes various specific details to aid understanding, but these details should be considered exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the invention.

[0026] In the description of this utility model, the orientation descriptions, such as up, down, front, back, left, right, etc., are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] It should be understood that when one element (e.g., the first element) is “connected” to another element (e.g., the second element), the element may be directly connected to the other element, or there may be an intervening element (e.g., the third element) between the element and the other element.

[0028] Embodiments of this utility model provide a safety protection device for gas cylinder filling, such as... Figure 1-6 As shown, it includes:

[0029] The inflation device 100 includes an inflation tube 110 for filling gas cylinders.

[0030] The protective frame 200 has a protective state and a disarmed state. The protective frame 200 is provided with railings 210 at intervals. Two adjacent railings 210 form a gas cylinder placement space 220.

[0031] The first vertical drive device 300 is used to drive the protective frame 200 to move vertically. When the protective frame 200 moves vertically so that the inflation pipe 110 and the gas cylinder enter the gas cylinder placement space 220, the protective frame 200 is in a protective state; when the protective frame 200 moves away from the inflation pipe 110 and the gas cylinder, the protective frame 200 is in a disarmed state.

[0032] The inflation device 100 is used to inflate the gas cylinder. It includes an inflation hose 110 for connecting the gas source and the gas cylinder to facilitate gas transfer. The protective frame 200 is constructed by spaced-apart railings 210, forming a gas cylinder placement space 220 between adjacent railings 210. This design prevents injury to operators when the inflation hose 110 swings. The protective frame 200 has a protected state and a disarmed state, which can be switched as needed. When the protective frame is in the protected state, it effectively protects the gas cylinder and inflation device from external interference or accidents; when in the disarmed state, the protective frame is away from the gas cylinder and inflation device, facilitating the placement and removal of the gas cylinder by the operator. A first vertical drive device 300 is used to drive the protective frame 200 to move vertically. The vertical drive device can be implemented in various ways, such as a hydraulic cylinder, an electric push rod, or a pneumatic device. Before filling begins, the protective frame is in the disarmed state, away from the inflation hose and the gas cylinder placement area. The operator places the gas cylinder within the cylinder placement space. The disarming design of the protective frame facilitates quick loading and unloading of the cylinders, improving work efficiency. Once the cylinder is placed, the inflation hose connects to the cylinder's inflation port, and the first vertical drive device activates, propelling the protective frame vertically into its protective state. In this protective state, the frame encloses the cylinder and inflation device, creating a relatively closed and safe filling environment, preventing external interference and accidents.

[0033] The working principle of this utility model is as follows:

[0034] During the gas cylinder filling process, the gas cylinder is placed below the gas cylinder placement space 220 of the protective frame 200. The first vertical drive device 300 adjusts the height of the protective frame 200 according to the height of the gas cylinder or the position of the filling device 100. The filling device 100 fills the gas cylinder with gas through the filling tube 110, while the protective frame 200 restrains the filling tube 110, reducing the swing amplitude of the filling tube 110 under the impact of high-pressure gas, and reducing the risk of safety accidents caused by the swing of the filling tube 110.

[0035] In some embodiments, the inflation device 100 includes a second vertical drive device 120 for driving the inflation tube 110 to move in a vertical direction.

[0036] The inflation tube 110 can move vertically independently of the protective frame 200 via the second vertical drive device 120. In actual operation, the height of the gas cylinder may vary depending on its model, specifications, or inflation status. The second vertical drive device 120 can adjust the position of the inflation tube 110 according to the actual height of the gas cylinder, ensuring that the inflation tube 110 can be smoothly inserted into the gas cylinder's inflation port. The first vertical drive device 300 is mainly responsible for adjusting the height of the protective frame 200 to accommodate gas cylinders of different heights; while the second vertical drive device 120 focuses on adjusting the position of the inflation tube 110 to ensure precise alignment with the gas cylinder's inflation port. Working together, they enable more flexible and precise filling operations. When encountering gas cylinders with significant height differences, the first vertical drive device 300 can first adjust the protective frame 200 to a roughly suitable position, and then the second vertical drive device 120 can make fine adjustments to ensure a perfect alignment between the inflation tube 110 and the gas cylinder's inflation port. This dual adjustment mechanism greatly improves the device's adaptability to different gas cylinders. The second vertical drive device 120 can adopt various drive methods, such as electric push rod, hydraulic cylinder or pneumatic device.

[0037] Furthermore, the inflation device 100 also includes a mounting bracket 130 for fixing the inflation tube 110, and the second vertical drive device 120 is connected to the mounting bracket 130.

[0038] The main function of the mounting bracket 130 is to fix the inflation tube 110, ensuring its stability during filling and preventing it from shaking due to external forces or vibrations. This helps improve the docking accuracy between the inflation tube 110 and the gas cylinder filling port, reducing the risk of gas leakage. The mounting bracket 130 provides stable support for the inflation tube 110, especially when the inflation tube 110 needs to move vertically, effectively preventing deformation or damage due to its own weight or external forces. The second vertical drive device 120, connected to the mounting bracket 130, can directly drive the mounting bracket 130 to move vertically, thereby moving the inflation tube 110 up and down. This connection method makes the movement of the inflation tube 110 more stable and precise, reducing errors that may occur due to indirect drive.

[0039] Furthermore, the bottom of the mounting bracket 130 is provided with a crash block 140, which can abut against the railing 210 when the mounting bracket 130 moves in the vertical direction.

[0040] The anti-collision block 140 is used to prevent the mounting frame 130 from directly colliding with the railing 210 of the protective frame 200 when the mounting frame 130 moves vertically. Such a collision could cause equipment damage, deformation of the inflation tube 110, or structural damage to the protective frame 200, and may even lead to a safety accident. The anti-collision block 140 is usually made of a material with a certain degree of elasticity and cushioning capacity (such as rubber, polyurethane, etc.), which can absorb the impact force when in contact with the railing 210, reducing the impact and damage to the equipment. The anti-collision block 140 also acts as a limiter, ensuring that the vertical movement range of the mounting frame 130 is controlled within a safe range, preventing the mounting frame 130 from exceeding the predetermined stroke and damaging the equipment or causing operational errors. The anti-collision block 140 effectively reduces equipment damage and safety accidents caused by collisions, improving the safety of the entire device. Through its cushioning and limiting functions, the anti-collision block 140 can protect key components such as the inflation tube 110, the mounting frame 130, and the protective frame 200, extending the service life of the equipment.

[0041] In some embodiments, a safety protection device for filling gas cylinders further includes an outer frame 400, which surrounds the outer side of the protective frame 200.

[0042] The outer frame 400 is the main structure of the device, providing a stable support platform for the protective frame 200, the inflation device 100, and other components. It can withstand the weight of the entire device and various forces that may be generated during the filling process (such as the pressure of the gas cylinder and the vibration of the inflation hose 110). The outer frame 400 encloses the protective frame 200 and the gas cylinder, forming a closed or semi-closed space. This design effectively prevents external objects from accidentally entering the device, avoiding interference or damage to the gas cylinder or inflation device 100, while also protecting operators from potential hazards. The outer frame 400 provides stable support for the protective frame 200, ensuring that it does not sway or tilt when moving vertically. Simultaneously, the inner wall of the outer frame 400 acts as a limiting device for the protective frame 200, preventing it from exceeding its predetermined travel distance, further improving the safety of the device. The dual protection design of the outer frame 400 and the protective frame 200 effectively isolates the gas cylinder filling area from the external environment, reducing external interference and potential hazards, and further enhancing the safety of the device.

[0043] Furthermore, the protective frame 200 and the outer frame 400 are slidably connected in the vertical direction.

[0044] Through a sliding connection, the protective frame 200 can move freely vertically within the outer frame 400, thus adapting to gas cylinders of different heights or filling requirements. The sliding connection design makes the movement of the protective frame 200 within the outer frame 400 smoother, reducing swaying and vibration, and further improving the stability of the device. In some embodiments, a vertical slide rail can be provided inside the outer frame 400, and the protective frame 200 achieves smooth vertical movement by cooperating with the slide rail via a slider.

[0045] Furthermore, the first vertical drive device 300 includes a driver 310, a chain 330, and a sprocket 340 meshing with the chain 330. The driver 310 is mounted on the outer frame 400. One end of the chain 330 is connected to the outer frame 400, and the other end is connected to the protective frame 200. The sprocket 340 is connected to the driver 310, and the driver 310 is used to drive the sprocket 340 to move in the vertical direction.

[0046] The actuator 310 can employ various driving methods, such as an electric actuator, hydraulic cylinder, or pneumatic device. The chain 330 transmits power to the actuator 310, enabling the vertical movement of the protective frame 200. The sprocket 340 meshes with the chain 330, and through the drive of the actuator 310, it drives the chain 330, thereby raising and lowering the protective frame 200. The actuator 310 drives the chain 330 via the sprocket 340, and the movement of the chain 330 causes the protective frame 200 to move vertically up and down. The chain 330 and sprocket 340 can achieve relatively precise transmission ratio and position control. By adjusting the speed and direction of the actuator 310, the raising and lowering speed and position of the protective frame 200 can be flexibly controlled.

[0047] In some embodiments, the inflation device 100 further includes a safety lock 160, which is connected to the inflation tube 110.

[0048] The safety lock 160 is fixed to the gas cylinder by mechanical locking to prevent the inflation hose 110 from accidentally detaching from the gas cylinder inflation port due to external forces (such as vibration, collision or human error) and causing injury to the operator.

[0049] Furthermore, the inflation tube 110 includes an inflation connector 150, and a safety lock 160 is connected to the inflation connector 150.

[0050] The inflation connector 150 is the connecting component between the inflation hose 110 and the gas cylinder inflation port, responsible for achieving sealed gas transmission. It has a threaded or snap-fit ​​structure that matches the gas cylinder inflation port, ensuring a secure and airtight connection. When the inflation connector 150 is inserted into the gas cylinder inflation port, the safety lock 160 is fixed to the gas cylinder to prevent the inflation connector 150 from accidentally disengaging from the gas cylinder inflation port due to external forces (such as vibration, impact, or human error), which could cause injury to the operator.
