Description

Technical Field

[0001] This utility model relates to the field of liquid oxygen filling technology, specifically a cylinder clamping device for cryogenic liquid oxygen filling. Background Technology

[0002] During the filling process of liquid oxygen in a low-temperature environment, pressure changes and vibrations will occur due to the extremely low temperature of liquid oxygen. In order to prevent safety accidents such as leakage and collision caused by shaking and displacement of the cylinder, the cylinder must be stably fixed to ensure the safety and accuracy of the filling operation.

[0003] Current cylinder clamping devices on the market exhibit significant limitations when dealing with cylinders of different specifications and shapes, resulting in poor clamping stability and versatility. On the one hand, most clamping devices employ a fixed structure design. When faced with cylinders of varying diameters, the traditional fixed-space clamping arms cannot tightly adhere to the cylinder surface, easily leading to loosening. This causes the cylinder to shake during filling, affecting filling accuracy and potentially causing safety accidents due to collisions. On the other hand, even those clamping devices with adjustment functions often have cumbersome and complex adjustment methods, requiring significant time and manpower for reinstallation and debugging. This greatly reduces work efficiency, making it difficult to meet diverse production needs and severely hindering the efficient and safe development of the liquid oxygen filling industry. Utility Model Content

[0004] The purpose of this invention is to provide a cylinder clamping device for filling cryogenic liquid oxygen, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cylinder clamping device for filling cryogenic liquid oxygen, comprising a base and a limiting mechanism, wherein the limiting mechanism is disposed inside the base.

[0006] The limiting mechanism consists of a first spur gear, a motor, a second spur gear, a rotating shaft, a third spur gear, a first bevel gear, a threaded rod, a second bevel gear, a threaded sleeve, a connecting rod, and a clamping plate. The first spur gear is rotatably mounted inside the base, the motor is fixedly mounted inside the base, the second spur gear is fixedly mounted on the output shaft of the motor, the rotating shaft is rotatably mounted inside the base, the third spur gear is fixedly mounted on the surface of the rotating shaft, the first bevel gear is fixedly mounted on the surface of the rotating shaft, the threaded rod is rotatably mounted inside the base, the second bevel gear is fixedly mounted on the surface of the threaded rod, the threaded sleeve is threadedly mounted on the surface of the threaded rod, the connecting rod is fixedly mounted on the top of the threaded sleeve, and the clamping plate is fixedly mounted on the side of the connecting rod.

[0007] Preferably, the first spur gear and the second spur gear mesh. When the motor is powered on and starts working, its output shaft generates rotational power, which directly drives the second spur gear, which is closely connected to it, to rotate. Since the first spur gear and the second spur gear are in a meshing state, relying on the precise tooth profile matching and meshing transmission principle between the gears, the tangential force generated when the second spur gear rotates will be transmitted to the first spur gear, thereby driving the first spur gear to rotate.

[0008] Preferably, the first spur gear and the third spur gear mesh. When the first spur gear starts to rotate under the action of external force, its teeth mesh tightly with the teeth of the third spur gear. Through the mechanical principle of gear transmission, the rotational power is accurately transmitted. After the third spur gear obtains power, it transmits torque to the rotating shaft by means of its coaxial fixed connection with the rotating shaft, thereby driving the rotating shaft to start rotating synchronously.

[0009] Preferably, the first bevel gear and the second bevel gear mesh. When the shaft starts to rotate under the action of external force, the first bevel gear fixedly connected to it rotates synchronously. Since the first bevel gear and the second bevel gear are in a perpendicular meshing state, the rotation of the first bevel gear transmits power to the second bevel gear through the mutual meshing between the tooth surfaces. The second bevel gear is coaxially connected to the threaded rod, thereby transmitting the rotational power to the threaded rod, and finally driving the threaded rod to start rotating.

[0010] Preferably, the base has a groove inside that matches the connecting rod, which facilitates the movement of the connecting rod inside the base.

[0011] Preferably, the side of the clamping plate is provided with a rubber sleeve. When the clamping plate clamps the cylinder, the soft and elastic properties of the rubber sleeve can closely fit the surface of the cylinder, increasing the contact area between the two, thereby achieving a more stable and reliable clamping and fixing of the cylinder, and effectively preventing the cylinder from sliding or shifting during transportation or storage.

[0012] Preferably, the number of the rotating shaft, the third spur gear, the first bevel gear, the threaded rod, the second bevel gear, the threaded sleeve, and the connecting rod are all one, and the two clamping plates are arranged in a circumferential array on the surface of the first spur gear. Multiple sets of this component can better clamp and fix the gas cylinder.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the cylinder clamping device for cryogenic liquid oxygen filling drives the second spur gear to rotate by starting the motor. Under the action of the first and third spur gears, the rotating shaft can be rotated. Under the action of the first and second bevel gears, the threaded rod can be rotated, so that the threaded sleeve drives the connecting rod to move. Cylinders of different specifications can be clamped and fixed by the clamping plate, effectively preventing the cylinders from sliding and shifting during transportation or storage.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a cylinder clamping device for filling cryogenic liquid oxygen, including a base 1 and a limiting mechanism 2, wherein the limiting mechanism 2 is disposed inside the base 1.

[0021] The limiting mechanism 2 consists of a first spur gear 201, a motor 202, a second spur gear 203, a rotating shaft 204, a third spur gear 205, a first bevel gear 206, a threaded rod 207, a second bevel gear 208, a threaded sleeve 209, a connecting rod 210, and a clamping plate 211. The first spur gear 201 is rotatably mounted inside the base 1, the motor 202 is fixedly mounted inside the base 1, and the second spur gear 203 is fixedly mounted on the output shaft of the motor 202. The first spur gear 201 and the second spur gear 203 mesh. When the motor 202 is powered on and starts working, its output shaft generates rotational power, directly driving the second spur gear 203, which is closely connected to it, to rotate. Gears 203 are in a meshing state. Relying on the precise tooth profile fit and meshing transmission principle between gears, the tangential force generated when the second spur gear 203 rotates is transmitted to the first spur gear 201, thereby driving the first spur gear 201 to rotate. The rotating shaft 204 is rotatably mounted inside the base 1, and the third spur gear 205 is fixedly mounted on the surface of the rotating shaft 204. The first spur gear 201 and the third spur gear 205 mesh. When the first spur gear 201 starts to rotate under the action of external force, its teeth mesh tightly with the teeth of the third spur gear 205. Through the mechanical principle of gear transmission, the rotational power is precisely transmitted. After receiving power, the third spur gear 205, through its coaxial fixed connection with the rotating shaft 204, transmits the torque. The power is delivered to the rotating shaft 204, causing the shaft 204 to rotate synchronously. The first bevel gear 206 is fixedly mounted on the surface of the rotating shaft 204, the threaded rod 207 is rotatably mounted inside the base 1, and the second bevel gear 208 is fixedly mounted on the surface of the threaded rod 207. The first bevel gear 206 and the second bevel gear 208 mesh. When the rotating shaft 204 starts to rotate under the action of external force, the first bevel gear 206, which is fixedly connected to it, rotates synchronously. Since the first bevel gear 206 and the second bevel gear 208 are in a perpendicular meshing state, the rotation of the first bevel gear 206 transmits power to the second bevel gear 208 through the meshing between the tooth surfaces. The second bevel gear 208 is coaxially connected to the threaded rod 207, thereby transmitting the rotational power. The signal is transmitted to the threaded rod 207, which ultimately drives the threaded rod 207 to rotate. The threaded sleeve 209 is threaded onto the surface of the threaded rod 207. The connecting rod 210 is fixedly installed on the top of the threaded sleeve 209. The base 1 has a groove inside that matches the connecting rod 210, facilitating movement of the connecting rod 210 within the base 1. A clamping plate 211 is fixedly installed on the side of the connecting rod 210. A rubber sleeve is provided on the side of the clamping plate 211. When the clamping plate 211 clamps the cylinder, the soft and elastic nature of the rubber sleeve allows it to closely conform to the cylinder surface, increasing the contact area between them. This results in a more stable and reliable clamping and fixing of the cylinder, effectively preventing slippage or displacement during handling or storage.The rotating shaft 204, the third spur gear 205, the first bevel gear 206, the threaded rod 207, the second bevel gear 208, the threaded sleeve 209, and the connecting rod 210 are each present in one unit, along with two clamping plates 211, arranged in a circumferential array on the surface of the first spur gear 201. Multiple sets of this assembly are provided for better clamping and securing of the gas cylinder.

[0022] When in use, the gas cylinder is placed on top of the base 1, and the motor 202 is started to drive the second spur gear 203 to rotate. Under the action of the first spur gear 201 and the third spur gear 205, the rotating shaft 204 can be rotated. Under the action of the first bevel gear 206 and the second bevel gear 208, the threaded rod 207 can be rotated, so that the threaded sleeve 209 drives the connecting rod 210 to move. The clamping plate 211 can clamp and fix gas cylinders of different specifications, effectively preventing the gas cylinders from sliding and shifting during transportation or storage.
