Description

Technical Field

[0001] The utility model belongs to the technical field of cylinder filling devices, and particularly relates to a filling device. Background Art

[0002] A cylinder filling device is a device for filling cylinders, mainly used for pressurized filling of high-pressure gases, liquefied gases or mixed gases. Currently, common cylinder filling devices mainly consist of: a frame, a gas storage tank, a pressurized filling mechanism, a control and monitoring system, etc., as well as accessory fittings such as pressure gauges, valves, and filling hoses. When in use, the filling hose is connected to the cylinder and the pressurized filling mechanism, and the gas to be filled is transported into the cylinder for storage through the pressurized filling mechanism.

[0003] Since cylinders are usually cylindrically arranged, during the filling process of the cylinder filling device for cylinders, a corresponding mechanism is required to clamp and fix the cylinder. In the prior art, most cylinder filling devices use the method of bolt-fixed assembly frames to clamp and limit the cylinders to be filled. Although this method can clamp and limit the cylinders, the convenience of loading, unloading, and limiting and fixing the cylinders is poor in actual application, making the filling process of the cylinder filling device for cylinders more cumbersome and complex.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a filling device.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

The sliding guide assembly 3 includes a pair of stoppers 301, and both of the pair of stoppers 301 are fixedly assembled on the side wall of the limit bottom plate 203. The limit bottom plate 203 is slidably guided by slidingly guiding the stoppers 301.

[0050] As Figures 3 to 5 shown in the figure, a guide slider 302 is fixedly assembled between the pair of stoppers 301. The guide slider 302 is used to assemble and limit the stoppers 301 and slide and guide them.

[0051] As Figures 3 to 4 shown in the figure, a pair of plug-in limit holes are opened in each of the pair of stoppers 301. A pair of positioning holes are opened on the side of the guide slider 302 close to the limit bottom plate 203, and the pair of positioning holes are arranged corresponding to the plug-in limit holes.

The sliding limit frame 205 and a plurality of fixing frames 204 cooperate with each other to clamp both sides of the plurality of gas cylinders 101, realizing the clamping and fixing of the gas cylinders 101.

[0057] Then, the supporting base 201 is pushed into the frame 1 in a manner that a force can be continuously applied to the disassembly and assembly handle 211. The supporting base 201 moves into the frame 1 under the action of multiple sets of universal wheels 202. Meanwhile, during the movement of the supporting base 201, the movement of the supporting base 201 can be guided by the sliding of the guiding slider 302 along the guiding slide bar 303. Finally, the pushing process of the supporting base 201 is limited by the mutual contact between the limiting top block 212 and the frame 1, completing the assembly of the gas cylinder 101. After the filling is completed, the clamping and fixing process of the gas cylinder 101 can be released by pulling out the supporting base 201 and lifting the disassembly and assembly handle 211 to disassemble the sliding limiting frame 205. Subsequently, the filled gas cylinder 101 can be unloaded.
