Description

Technical Field

[0001] This utility model relates to the field of gas cylinder filling technology, and in particular to a fixing clamp for gas cylinder filling. Background Technology

[0002] In the field of industrial gas filling, the secure clamping of gas cylinders is a core element in ensuring filling safety, thus requiring a fixing fixture for gas cylinder filling.

[0003] Traditional gas cylinder clamps often use simple hydraulic rods to clamp and fix the gas cylinders, which generally suffer from the problem that the clamping force is not adjustable. When clamping and fixing large gas cylinders, insufficient clamping force will cause the gas cylinder to be unstable during the filling process. When clamping and fixing small gas cylinders, excessive clamping force will cause damage to the surface of the gas cylinder, resulting in gas leakage. In order to solve the above problems, this application proposes a fixing clamp for gas cylinder filling. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixing clamp for gas cylinder filling. This clamp automatically clamps and secures the gas cylinder using a second pressure sensor; it can clamp and secure gas cylinders of different sizes using an adjustment mechanism; and through the cooperation of the first pressure sensor, the micro-host, and the operation panel, the clamping force can be adjusted according to the specifications of the gas cylinder, resulting in excellent clamping and securing performance.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fixing clamp for filling gas cylinders includes a base, a motor fixedly connected to the side wall of the base, a lead screw fixedly connected to the output end of the motor, the lead screw passing through the base and rotatably connected thereto, two columns threadedly connected to the lead screw sleeve on the outer wall of the lead screw, a sliding column slidably connected to the top of each column, an adjustment mechanism on each column, connecting rods fixedly connected to the opposite ends of the two columns and the sliding column, a clamping plate fixedly connected to the end of each connecting rod, a first pressure sensor fixedly connected to the inner wall of the clamping plate, a second pressure sensor fixedly connected to the top of the base, and a micro-host, an operation panel, and buttons fixedly connected to the front end of the base.

[0007] Preferably, the adjusting mechanism includes a T-shaped rod that passes through and is rotatably connected to the column. A driving bevel gear is fixedly connected to the end of the T-shaped rod. The driving bevel gear meshes with a driven bevel gear. A threaded rod is fixedly connected to the driven bevel gear. The bottom of the threaded rod is rotatably connected to the column. The threaded rod is threadedly connected to the sliding column.

[0008] Preferably, the lead screw is provided with two external threads with opposite directions, and the two columns are respectively sleeved on the outer walls of the two external threads with opposite directions.

[0009] Preferably, the top of the base has two sliding grooves, and the outer walls of the two columns are slidably connected to the inner walls of their corresponding sliding grooves.

[0010] Preferably, a square block is fixedly connected to the outer wall of the sliding column, and the square block is located inside the column and slidably connected to its inner wall.

[0011] Preferably, the clamp is provided with a first groove, the first pressure sensor is located in the first groove and fixedly connected thereto, and the base is provided with a second groove, the second pressure sensor is located in the second groove and fixedly connected thereto.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] 1. Through the coordinated action of the first and second pressure sensors, real-time monitoring and closed-loop control of clamping force are achieved, ensuring precise matching of clamping force for gas cylinders of different specifications (e.g., high clamping force for large-volume gas cylinders and low clamping force for small-volume gas cylinders), avoiding overpressure damage or unstable clamping.

[0014] 2. After the second pressure sensor detects the placement of the gas cylinder, it automatically starts the motor to drive the lead screw, reducing manual intervention, improving operating efficiency, and automatically clamping and fixing the gas cylinder.

[0015] 3. The two opposing threads of the lead screw drive the two upright columns to move relative to each other or away from each other, thereby automatically adjusting the gap between the clamping plates and adapting to gas cylinders of different diameters. Manually rotating the T-shaped rod drives the bevel gear set and the threaded rod to raise and lower the sliding column, adjusting the height of the upper clamping plate and adapting to gas cylinders of different heights, thus expanding the applicability of the clamp.

[0016] In summary, the second pressure sensor can automatically clamp and fix the gas cylinder; the adjustment mechanism can clamp and fix gas cylinders of different sizes; and the combination of the first pressure sensor, the micro-host, and the operation panel can adjust the clamping force according to the specifications of the gas cylinder, resulting in excellent gas cylinder clamping and fixing effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A fixing clamp for filling gas cylinders includes a base 1, a motor 2 fixedly connected to the side wall of the base 1, a lead screw 3 fixedly connected to the output end of the motor 2, the lead screw 3 passing through the base 1 and rotatably connected thereto, two columns 5 threadedly connected to the lead screw 3 on the outer wall of the lead screw 3, and two external threads with opposite directions on the lead screw 3, the two columns 5 respectively fitted on the outer walls of the two external threads with opposite directions, two sliding grooves 4 opened on the top of the base 1, the outer walls of the two columns 5 respectively slidably connected to the inner walls of their corresponding sliding grooves 4, the motor 2 can drive the lead screw 3 to rotate, so that the columns 5 on both sides can move relative to each other or away from each other, so as to clamp and fix the gas cylinder.

[0024] Each column 5 has a sliding column 6 slidably connected to its top. A square block is fixedly connected to the outer wall of the sliding column 6. The square block is located inside the column 5 and slidably connected to its inner wall, which can limit the sliding column 6 to move up and down within the column 5. Each column 5 is equipped with an adjustment mechanism, which includes a T-shaped rod 10 that passes through the column 5 and is rotatably connected to it. A driving bevel gear 11 is fixedly connected to the end of the T-shaped rod 10. The driving bevel gear 11 meshes with a driven bevel gear 12. A threaded rod 13 is fixedly connected to the driven bevel gear 12. The bottom of the threaded rod 13 is rotatably connected to the column 5. The threaded rod 13 is threadedly connected to the sliding column 6. By gripping and rotating the T-shaped rod 10, the sliding column 6 can be moved up and down, and the two upper clamping plates 8 can be moved up and down. The height of the two upper clamping plates 8 can be adjusted according to the height of the gas cylinder, resulting in a good clamping effect on the gas cylinder.

[0025] Two upright columns 5 and a sliding column 6 are fixedly connected to opposite ends of a connecting rod 7. Each connecting rod 7 is fixedly connected to a clamping plate 8 at its end. The clamping plate 8 is arc-shaped, which can increase the contact area between the clamping plate 8 and the gas cylinder, resulting in a better clamping effect. A first pressure sensor 9 is fixedly connected to the inner wall of the clamping plate 8. A first groove is provided on the clamping plate 8. The first pressure sensor 9 is located in the first groove and fixedly connected to it. When the gas cylinder is clamped by the clamping plate 8, the first pressure sensor can detect the clamping force, so that the clamping force is equal for the same specification of gas cylinder each time. The clamping force can be preset through the operation panel 16, thereby clamping and limiting gas cylinders of different sizes.

[0026] A second pressure sensor 14 is fixedly connected to the top of the base 1. A second groove is provided on the base 1, and the second pressure sensor 14 is located in the second groove and fixedly connected to it. When the gas cylinder is placed on the base 1, the second pressure sensor 14 senses the pressure and transmits the signal to the micro-host 15. The micro-host 15 controls the motor 2 to start, thereby automatically clamping and fixing the gas cylinder. The front end of the base 1 is fixedly connected to the micro-host 15, the operation panel 16, and the button 17. The clamping force can be preset on the operation panel 16 to automatically clamp gas cylinders of different sizes. The clamping force can be adjusted for different sizes of gas cylinders. The clamping force is greater for large-volume gas cylinders and less for small-volume gas cylinders, thereby protecting the gas cylinder and achieving a good clamping effect.

[0027] In this invention, when the gas cylinder needs to be positioned, the operator places the gas cylinder between the two sets of clamping plates 8 and onto the base 1. At this time, the second pressure sensor 14 can sense the pressure signal and transmit it to the micro-host 15. The micro-host 15 controls the motor 2 to start, and the output end of the motor 2 drives the lead screw 3 to rotate, causing the columns 5, sliding columns 6, connecting rods 7, and clamping plates 8 on both sides to move relative to each other until the two sets of clamping plates 8 abut against the two ends of the gas cylinder, completing the automatic clamping and fixing of the gas cylinder. When the clamping plates 8 contact the outer wall of the gas cylinder, the first pressure sensor 9 can monitor the clamping force and transmit the value to the micro-host 15. When the clamping force value reaches the threshold of the micro-host 15, the micro-host 15 controls the motor 2 to stop running, so that the clamping force of the two sets of clamping plates 8 on the gas cylinder reaches the predetermined value. The threshold is set before the gas cylinder is filled, ensuring its stability during filling. The distance between the two clamping plates 8 can be adjusted to clamp and fix gas cylinders of different sizes. The clamping force can be preset via the control panel 16. When the clamping force reaches the preset value, clamping stops. The clamping force can be adjusted according to the gas cylinder's specifications, providing excellent clamping effect for different sizes. After filling, pressing button 17 controls the output of motor 2 to rotate in the reverse direction, releasing the gas cylinder for removal and replacement. The operator holds the T-shaped rod 10 and rotates it, driving the active bevel gear 11, driven bevel gear 12, and threaded rod 13 to rotate, causing the sliding column 6 to slide on the column 5, thereby adjusting the height of the two clamping plates 8. This allows for clamping of gas cylinders of different sizes, making it widely applicable.
