As shown in fig. 1 to 3, a carbon dioxide extinguisher filling equipment can be provided with a plurality of filling stations 2 simultaneously including being equipped with the removal frame 1 on the removal frame 1, in this embodiment, is provided with two filling stations 2 totally of left station and right station on the removal frame 1, and the filling is being carried out in the filling man-hour in turn each other.

Filling station 2 is including weighing sensor 3, support 7, and gas charging component, weighing sensor 3 passes through chassis 11 fixed mounting on moving frame 1, fixed mounting is supporting 7 and slide rail 18 on weighing sensor 3's weighing platform 19, support 7 main part is the C style of inversion, be equipped with restriction part 8 in the one end that support 7 keeps away from weighing sensor 3, restriction part 8 mainly used restricts the position and the angle of fire extinguisher so that automatic filling, consequently only need can fix the fire extinguisher, consequently can directly adopt conventional anchor clamps etc. as restriction part 8, in this embodiment, restriction part 8 has mainly used can fix the fire extinguisher with the setting element that groove structure on the fire extinguisher corresponds, make the fire extinguisher fix at support 7. After the fire extinguisher is fixed on the bracket 7, a fire extinguisher press handle driving piece 9 fixedly arranged on the bracket 7 is arranged above the position opposite to the fire extinguisher press handle.

The inflation assembly comprises a valve displacement driving piece 4, an inflation valve 5 and an inflation nozzle 10, the valve displacement driving piece 4 is fixedly arranged at one end, far away from the limiting part 8, of the support 7, the movable part of the valve displacement driving piece is fixedly connected with the inflation valve 5, the inflation valve 5 is arranged on a slide rail 18 of a weighing platform 19 through a slide block 17, and the inflation nozzle 10 is arranged at one side, far away from the valve displacement driving piece 4, of the inflation valve 5; during normal operation, the valve displacement driving member 4 pushes the charging valve 5 so that the charging nozzle 10 is fitted to the air inlet of the fire extinguisher that has been fixed for charging, and after the charging is completed, the valve displacement driving member 4 pulls back the charging valve 5 so that the fire extinguisher to be charged can be replaced by a worker.

In order to realize the automatic opening and closing of the inflation valve 5, a valve driving member 6 is fixedly installed above the inflation valve 5, and when the valve displacement driving member 4 pushes the inflation valve 5, the valve driving member 6 on the inflation valve 5 moves together with the inflation valve. And still be equipped with a plurality of carbon dioxide air inlets 16 on the side that inflation valve 5 is close to valve displacement driving piece 4, carbon dioxide air inlet 16 can be used for connecting the carbon dioxide gas cylinder or the equipment of direct connection production carbon dioxide, and a plurality of carbon dioxide air inlets 16 can connect a plurality of gas cylinders simultaneously to can accomplish to change under the circumstances of not stopping aerifing and consume the gas cylinder totally, also can only use one of them carbon dioxide air inlet 16 to connect production facility, or connect production facility and gas cylinder simultaneously. When the embodiment is connected to the filling pressurization system, the filling pressurization system needs to continuously output pressure after being started, and can not be stopped midway, otherwise, pipelines are easy to freeze and block, so that normal filling can not be performed, and the pipelines have overpressure when the filling is discontinuously performed, so that two stations are required for alternative filling.

Be equipped with the pulley 15 that can carry out the auto-lock in the bottom that removes frame 1, pulley 15 can freely change the place according to the demand, improves the convenience of this embodiment, can carry out the auto-lock again simultaneously in order to guarantee the holistic stability of equipment when normal filling. A bottom support 14 is arranged on the movable frame 1 corresponding to the bottom of the fire extinguisher, and the bottom support 14 can freely move up and down through threads.

Because gas charging component and support 7 etc. all set up on weighing sensor 3's weighing platform 19, when carbon dioxide in the fire extinguisher is gradual increase, its weight also will increase gradually, along with the increase of whole weight on weighing platform 19, weighing platform 19 itself also will move down certain distance for the bottle bottom of fire extinguisher then just in time falls on collet 14 when the filling finishes.

The support 7 is also provided with a protective baffle 13, and the protective baffle 13 can reciprocate in the vertical direction through a baffle driving piece 12 fixedly arranged on the side surface of the support 7; after the fire extinguisher is fixed on the limiting component 8, the protective baffle 13 can block the contact part of the fire extinguisher and the charging nozzle 10 under the driving of the baffle driving piece 12, so that firstly, a worker can be prevented from mistakenly touching a pressing handle of the fire extinguisher, secondly, the residual carbon dioxide at the charging nozzle 10 can be prevented from being sprayed to the worker when the charging nozzle 10 is separated from the fire extinguisher, and the filling carbon dioxide is in a high-pressure low-temperature state, so that certain danger is realized, and the protective baffle 13 can effectively protect an operator working beside; after the fire extinguisher is filled, the baffle driving member 12 drives the protective baffle 13 to move upwards, so that the next fire extinguisher can be replaced conveniently for filling.

Valve displacement drive piece 4, valve drive piece 6 and fire extinguisher pressure handle drive piece 9 all can adopt cylinder or reciprocating motor etc. to drive, and in this embodiment, all drive pieces all adopt the cylinder to drive.

The principle of the embodiment of the application is as follows:

when the fire extinguisher is filled, firstly, an empty fire extinguisher is installed on the limiting part 8, the inflation valve 5 and the inflation nozzle 10 move forwards together under the driving of the valve displacement driving piece 4, the inflation nozzle 10 is tightly abutted with an air inlet of the fire extinguisher, then the valve driving piece 6 and the fire extinguisher press handle driving piece 9 extend out simultaneously, the inflation valve 5 and the fire extinguisher press handle are synchronously opened, the two are communicated with each other, so that the fire extinguisher is filled, and meanwhile, the weighing sensor 3 synchronously records the real-time weight of the fire extinguisher; when the filling amount of carbon dioxide in the fire extinguisher meets the requirement, the valve driving piece 6 and the fire extinguisher press handle driving piece 9 retract synchronously, the inflation valve 5 and the fire extinguisher press handle are closed, and the filling of the carbon dioxide is completed; finally, the valve displacement driving piece 4 drives the inflation valve 5 and the inflation nozzle 10 to move backwards, so that the inflation valve and the inflation nozzle are far away from the fire extinguisher, then workers take down the filled fire extinguisher, and replace the fire extinguisher to be filled to continue the filling process.

Because the valve driving piece 6 and the fire extinguisher press handle driving piece 9 can be directly and automatically opened or closed according to the information fed back by the weighing sensor 3, the purpose of automatically controlling air charging is achieved, and simultaneously, the dosage of carbon dioxide filled in the fire extinguisher can be accurately controlled; the workman only need take off the fire extinguisher that the filling finishes when normal filling, again the replacement treat the filling the fire extinguisher can, reduced the step of control flap and accurate dosage, the effectual filling efficiency that has improved.

The embodiments of the present invention are preferred embodiments of the present application, and the protection scope of the present application is not limited thereby, wherein like parts are denoted by like reference numerals. Therefore, the method comprises the following steps: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
