Description

Technical Field

[0001] This utility model relates to the field of nitrogen charging technology for accumulators, specifically to a nitrogen charging device for accumulators. Background Technology

[0002] An accumulator is an energy storage device in a hydraulic and pneumatic system. It converts the energy in the system into compressed energy or potential energy and stores it at the appropriate time. When the system needs it, it converts the compressed energy or potential energy into hydraulic or pneumatic energy and releases it to replenish the system. When the system pressure increases instantaneously, it can absorb this part of the energy to ensure that the pressure of the entire system is normal. During the use of the accumulator, it is necessary to fill it with nitrogen.

[0003] For example, Chinese utility model patent CN202323208375.0 describes a nitrogen charging device for an accumulator. By adjusting the rotation direction of the first knob, the first threaded block can move up and down on the outer wall of the one-way threaded rod. The first threaded block can drive the connecting ring to move up and down, which in turn drives the second high-pressure hose and the connector to move up and down, positioning the connector directly above the accumulator and connecting it to the accumulator. However, this device can only adjust the height of the connector and cannot adjust the orientation of the connector or the distance between the connector and the accumulator connection port according to the position of the accumulator. This results in significant limitations and affects the nitrogen charging efficiency of the device. Utility Model Content

[0029] An accumulator is an energy storage device in a hydraulic and pneumatic system. It converts the energy in the system into compressed energy or potential energy and stores it at the appropriate time. When the system needs it, it converts the compressed energy or potential energy into hydraulic or pneumatic energy and releases it to replenish the system. When the system pressure increases instantaneously, it can absorb this part of the energy to ensure that the pressure of the entire system is normal. During the use of the accumulator, it is necessary to fill it with nitrogen.

[0030] In related technologies, only the height of the connector can be adjusted. It is not possible to adjust the orientation of the connector and the distance between the connector and the accumulator connection port according to the position of the accumulator, which results in high limitations and affects the nitrogen charging efficiency of the equipment.

[0031] To address some of the problems in related technologies, this application provides a nitrogen charging device for an accumulator. When it is necessary to connect the connector 14 to the connection port on the accumulator, simply rotate the rotating rod 25 to rotate the connector 14 on the movable plate 241 so that the angle of the connector 14 is aligned with the accumulator. The rotating rod 25 is then fixed by the fixing component 26. Subsequently, the movable plate 241 is pulled to extend and retract within the sleeve plate 24, thereby moving the connector 14 on the movable plate 241 directly above the connection port at the top of the accumulator. Then, the lifting component 22 is activated to push the support plate 23 down, thereby allowing the connector 14 on the movable plate 241 to be docked and fixed with the connection port at the top of the accumulator.

[0032] This application is described below with reference to the accompanying drawings and specific embodiments:

[0033] Combination Figures 1-4This application provides a nitrogen charging device for an accumulator, including a device body 1. The device body 1 includes: a nitrogen cylinder 12 disposed on the top of a frame 11; a charging pump 13 disposed on the top of the frame 11 and located on one side of the nitrogen cylinder 12, and connected to the nitrogen cylinder 12 via a gas supply pipe; an adjustment assembly 2 disposed on the top of the frame 11, the adjustment assembly 2 including: a support column 21 disposed on the top of the frame 11 and located on one side of the charging pump 13; a lifting assembly 22 passing through the support column 21; a support plate 23 disposed on the lifting assembly 22 and located on the outside of the support column 21; a rotating rod 25 passing through the support plate 23 and rotatably connected to the support plate 23; a fixing assembly 26 disposed on the outside of the rotating rod 25; a sleeve plate 24 disposed at the bottom of the rotating rod 25; a movable plate 241 passing through one side of the sleeve plate 24; and a connector 14 passing through the movable plate 241 and connected to the charging pump 13 via a gas supply pipe.

[0034] In use, the nitrogen charging device is pushed near the accumulator. Then, by observing the position of the accumulator, the rotating rod 25 is rotated. The rotating rod 25 causes the connector 14 on the movable plate 241 to rotate and face the accumulator. The rotating rod 25 is then fixed by the fixing component 26. The movable plate 241 is then pulled, causing it to extend and retract within the sleeve 24, thereby moving the connector 14 on the movable plate 241 directly above the connection port at the top of the accumulator. Then, the lifting component 22 is activated, pushing the support plate 23 to descend, thereby aligning and fixing the connector 14 on the movable plate 241 with the connection port at the top of the accumulator. Finally, the valve on the nitrogen cylinder 12 is opened, and the charging pump 13 is started to charge the accumulator with nitrogen. This increases the flexibility of the connector 14's movement on the device, reduces its limitations, and improves the nitrogen charging efficiency of the accumulator.

[0035] Specifically, the model of the air pump 13 is SUP-B. The working principle of the air pump is as follows: the air pump uses a motor to drive the blades or piston to move, and generates compressed air or liquid flow by changing the volume, thereby injecting gas or liquid into the object being inflated. This part is not mentioned in the instruction manual.

[0036] In some embodiments, the fixing component 26 includes: a thread 261 disposed on the outside of the rotating rod 25; a threaded sleeve 262 disposed on the thread 261 and sleeved on the outside of the rotating rod 25. When the rotating rod 25 drives the connector 14 to rotate to a predetermined angle, the threaded sleeve 262 is rotated, and the rotating threaded sleeve 262 moves downward and presses the top of the support plate 23, thereby pressing and fixing the rotating rod 25.

[0037] In some embodiments, the bottom of the threaded sleeve 262 is provided with a pressing plate 27, which is sleeved on the outside of the rotating rod 25, thereby increasing the pressing area of ​​the threaded sleeve 262 on the top of the support plate 23 and improving the stability of pressing and fixing the rotating rod 25.

[0038] In some embodiments, the bottom of the extrusion plate 27 is provided with an anti-slip pad 271 and is located at the bottom of the support plate 23, which increases the anti-slip properties of the extrusion plate 27 pressing the top of the support plate 23.

[0039] In some embodiments, a locking block 242 is provided on the top of the movable plate 241 and extends through the movable plate 241. A slot 243 is provided on the sleeve plate 24 to engage with the locking block 242. A spring 244 is provided between the locking block 242 and the movable plate 241. After the movable plate 241 extends or retracts, the locking block 242 on its top is engaged into the slot 243 on the sleeve plate 24 by the elastic support of the spring 244, so that the sleeve plate 24 and the movable plate 241 are engaged and fixed, which increases the stability of the connector 14 after the movable plate 241 moves. When the movable plate 241 is moved, the locking block 242 needs to be pressed to disengage the locking block 242 from the slot 243 and cancel the engagement and fixation.

[0040] In some embodiments, a limiting plate 28 is provided at one end of the movable plate 241 and is located inside the sleeve plate 24 to limit the movable plate 241 and prevent the movable plate 241 from coming out of the sleeve plate 24.

[0041] In some embodiments, the lifting assembly 22 includes: a motor 221 disposed at the top of the support column 21; a threaded rod 222 disposed at the output end of the motor 221 and passing through the support column 21; and a moving block 223 sleeved on the outside of the threaded rod 222 and passing through the outside of the support column 21. The motor 221 drives the threaded rod 222 to rotate, and the rotating threaded rod 222 pushes the support plate 23 to rise and fall through the moving block 223.

[0042] In some embodiments, a slider 29 is provided on the outer side of the movable block 223, and a groove 291 that matches the slider 29 is provided on the inner side wall of the support column 21 to support the support plate 23 and limit the movable block 223 to prevent the movable block 223 from rotating with the threaded rod 222, which would cause the support plate 23 to shake.

Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.
