Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguisher filling, and specifically to a fire extinguisher pressurizing and inflating station. Background Art

[0002] After filling the dry powder in the fire extinguisher tank, it is necessary to perform pressurizing and inflating operations on it. This is mainly to provide jet power and ensure the stability of the internal pressure of the fire extinguisher, so as to ensure efficient and reliable operation in case of emergency.

[0003] The traditional inflation method mainly relies on manual operation. The specific operation process is as follows: The operator needs to first carry the fire extinguisher to the location where the inflation equipment is located and ensure that the inflation interface of the fire extinguisher is accurately aligned with the nozzle of the inflation gun. Subsequently, by manually pressing the control device on the handle of the fire extinguisher, the powder spraying valve (or equivalent inflation channel) is activated, so that high-pressure gas (such as nitrogen) can be injected into the fire extinguisher. After inflation, it is necessary to immediately insert the safety pin to prevent accidental opening of the fire extinguisher valve during subsequent operations. In short, the above operations are cumbersome, with a large labor intensity and low inflation efficiency. For this reason, we propose a fire extinguisher pressurizing and inflating station. Summary of the Invention

[0028] The present invention has at least the following beneficial effects:

[0029] 1. When the first driving member drives the fire extinguisher to move, the T-shaped limiting block deflects first to limit the fire extinguisher connector, and then drives the tray and the fire extinguisher to rotate.

Subsequently, the inflation head is docked with the inflation interface, and the deflection plate rotates to press the handle to open the valve, and the solenoid valve is opened to pressurize and inflate. After inflation, the deflection plate drives the handle to deflect until the safety pin insertion hole is aligned, the rectangular push plate is moved to insert the safety pin, and finally the first driving member resets to push out the fire extinguisher, completing pressurized inflation and installing the safety pin, reducing manual participation and improving the filling efficiency.

[0030] 2.

Detailed implementation manner

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1: Please refer to Figures 1-8 , the present invention provides a technical solution: A fire extinguisher pressurization and inflation platform includes an outer shell 1 and an inflation head 11 provided on the outer shell 1. The inflation head 11 is in communication with an external high-pressure gas supply device. The external high-pressure gas supply device can specifically be a nitrogen tank. The nitrogen tank is in communication connection with the inflation head 11 through a pressure reducing valve, a conduit, and a solenoid valve. It further includes:

[0042] A tray 2 is provided inside the outer shell 1 for supporting the fire extinguisher. When a staff member uses this device, only need to insert the fire extinguisher into the tray 2, and at the same time ensure that the general orientation of the fire extinguisher nozzle is specifically correct towards the side of the inflation head 11;

[0043] A first pusher 3 is provided inside the outer shell 1 and connected to the tray 2 for driving the tray 2 to move so as to drive the fire extinguisher to move to the position of the inflation head 11;

[0044] A deflection positioning member 4 is provided inside the outer shell 1 for driving the fire extinguisher to rotate when the tray 2 moves, so that the inflation interface of the fire extinguisher deflects and faces the inflation head 11;

[0045] A second pusher 5 is provided on the outer shell 1 for driving the inflation head 11 to move and dock with the inflation interface of the fire extinguisher;

[0046] The deflector plate 8 is arranged on the housing 1 and is used to open the fire extinguisher valve by rotating the deflector plate 8 after completing the docking with the fire extinguisher handle.

[0047] The storage box 6 is installed on the housing 1 and is used for stacking and storing safety pins.

[0048] The third pusher 7 is arranged on the housing 1 and is connected to the storage box 6, and is used to push the safety pin into the fire extinguisher handle.

[0049] Specifically, in the process of driving the fire extinguisher to move by the first pusher 3, the T-shaped limit block 72 is first driven to deflect and contact the fire extinguisher joint and limit it, and then the tray 2 and the fire extinguisher are driven to rotate. When the inflation interface of the fire extinguisher contacts and abuts against the T-shaped limit block 72, it stops rotating and deflects in place. Subsequently, the handle of the fire extinguisher is embedded between the two round rollers 54. Then, the inflation head 11 moves to dock with the fire extinguisher inflation interface, and then the fire extinguisher valve is opened by rotating the deflector plate 8 to press the handle. Then, the solenoid valve is opened to pressurize and inflate the fire extinguisher. After the inflation is completed, the deflector plate 8 rotates to actively drive the handle to deflect and open to a certain angle so that the safety pin insertion hole on the handle is aligned. Subsequently, the safety pin is inserted into the insertion hole on the handle by moving the rectangular push plate 58, and then the fire extinguisher is pushed out by the reset of the first pusher 3, thereby completing the pressurized inflation operation of the fire extinguisher and installing the safety pin on the fire extinguisher at the same time. The whole process greatly reduces manual participation and improves the filling efficiency of the fire extinguisher.

[0050] The first pusher 3 includes a guide rod 31 fixedly connected to the bottom of the housing 1. A slider 32 is slidably connected to the guide rod 31. The tray 2 is connected to the slider 32. A first shaft 33 is rotatably connected to the housing 1 through a bearing. A screw rod 34 is fixedly connected to the first shaft 33. The screw rod 34 threadedly penetrates through the slider 32. And a first driving motor 35 is fixedly connected to the housing 1. The output shaft of the first driving motor 35 is fixedly connected to the first shaft 33. By starting the first driving motor 35 to drive the first shaft 33 to rotate, the screw rod 34 is driven to rotate, thereby driving the slider 32 to slide along the guide rod 31 to drive the tray 2 and the fire extinguisher to move.

[0051] The deflection positioning member 4 includes an L-shaped plate 36 fixedly connected to the slider 32. A second shaft 37 is rotatably connected to the L-shaped plate 36 through a bearing. A first connecting rod 38 is fixedly connected to the second shaft 37. One end of the first connecting rod 38 is rotatably connected to a T-shaped limiting block 72 through a rotating shaft. And a second connecting rod 39 parallel to the first connecting rod 38 is arranged on one side of the first connecting rod 38. Both ends of the second connecting rod 39 are rotatably connected to the L-shaped plate 36 and the T-shaped limiting block 72 through rotating shafts respectively. Rotating the second shaft 37 drives the T-shaped limiting block 72 to deflect and contact the fire extinguisher connector. Specifically, after the fire extinguisher is pressurized and inflated, during the process of sending it out by moving the tray 2, it will drive the first connecting rod 38 and the second connecting rod 39 to deflect, and then drive the T-shaped limiting block 72 to deflect away from the fire extinguisher connector, thus avoiding blocking the installation and disassembly operations of the fire extinguisher;

[0052] And a swing plate 41 is fixedly connected to the second shaft 37. One end of the swing plate 41 is rotatably connected to a third shaft 42. And a rectangular plate 43 is fixedly connected to the housing 1. A guide groove member 45 is formed on the rectangular plate 43. One end of the third shaft 42 is located in the guide groove member 45 and is used to drive the third shaft 42 to slide along the guide groove member 45 when the L-shaped plate 36 moves, so as to drive the third shaft 42 to rotate;

[0053] A fourth shaft 46 is fixedly connected to the bottom end of the tray 2. The fourth shaft 46 is rotatably connected to the slider 32. And the inner wall of the tray 2 is made of rubber material, which is used to drive the fire extinguisher to rotate through friction when rotating the tray 2. With this design, when the fire extinguisher rotates in place, the tray 2 can continue to rotate without causing interference. A transmission member 47 is arranged between the fourth shaft 46 and the housing 1, which is used to drive the fourth shaft 46 to rotate when the slider 32 drives the fourth shaft 46 to move.

[0054] The guide groove member 45 includes a first straight chute 48 formed at one end of the rectangular plate 43. One end of the third shaft 42 is located in the first straight chute 48 and is slidably connected to its inner wall. And a second straight chute 49 is formed at the other end of the rectangular plate 43. An inclined chute 51 is formed on the rectangular plate 43, and both ends of the inclined chute 51 are communicated with the first straight chute 48 and the second straight chute 49 respectively. Specifically, when the T-shaped limiting block 72 is in the open state, the third shaft 42 is located in the first straight chute 48 and is slidably connected to its inner wall. During the process of the tray 2 driving the fire extinguisher to move, the third shaft 42 first slides along the first straight chute 48 to keep the T-shaped limiting block 72 in the open state. When the third shaft 42 slides along the inclined chute 51, it drives the swing plate 41 to deflect, and then drives the second shaft 37 to rotate, thereby driving the first connecting rod 38 and the second connecting rod 39 to deflect, so as to drive the T-shaped limiting block 72 to deflect in place. Subsequently, the third shaft 42 slides along the second straight chute 49 to keep the T-shaped limiting block 72 in the limiting state of the fire extinguisher connector.

[0055] The transmission member 47 includes a toothed disc 52 arranged on the fourth shaft 46. The toothed disc 52 is connected to the fourth shaft 46 through a one-way ratchet and pawl assembly, which is used to prevent it from rotating when the fire extinguisher is pushed out, avoiding interference. There is also a rack 53 fixedly connected to the bottom end of the outer shell 1. When the slider 32 is moved, the toothed disc 52 meshes with the rack 53 and rolls along the rack 53 to drive the fourth shaft 46 to rotate. Specifically, after the third shaft 42 slides along the inclined chute 51, the toothed disc 52 meshes with the rack 53 and rolls along it, and then rotates the fire extinguisher so that its connector deflects and contacts the T-shaped limit block 72, thereby positioning the fire extinguisher. This does not require manual placement by the staff and is relatively convenient and efficient.

[0056] One end of the deflection plate 8 is symmetrically and rotatably connected to two round rollers 54 through a rotating shaft, which is used to drive the handle of the fire extinguisher to fit into the gap between the two round rollers 54 when the fire extinguisher moves into place.

[0057] A second driving motor 55 is fixedly connected to the outer shell 1. The output shaft of the second driving motor 55 is fixedly connected to one end of the deflection plate 8. Starting the second driving motor 55 drives the deflection plate 8 to rotate, thereby driving the handle of the fire extinguisher to deflect.

[0058] Specifically, the control method of the handle of the fire extinguisher in this device is an active control. It can not only drive the handle to deflect to open the valve of the fire extinguisher, but also drive the handle to deflect to close the valve of the fire extinguisher, thereby ensuring that the valve of the fire extinguisher is closed.

[0059] The second pusher 5 includes an electric push rod 56 fixedly connected to the outer shell 1. The extended end of the electric push rod 56 is fixed to the inflation head 11, which is used to drive the inflation head 11 to move.

[0060] The inner cavity cross-section of the storage box 6 is designed the same as that of the safety pin, which is used to stack the safety pins neatly and ensure that the safety pins are facing in the correct direction.

[0061] The third pusher 7 includes an electric push rod 57 fixedly connected to the outer shell 1. The extended end of the electric push rod 57 is fixedly connected to a rectangular push plate 58. One end of the rectangular push plate 58 is designed in an arc shape to fit the safety pin. There is also a rectangular support plate 59 at the bottom end of the rectangular push plate 58, which is used to support the safety pin. A U-shaped block 61 is slidably connected to the rectangular support plate 59. When the U-shaped block 61 extends out of the rectangular support plate 59, it is used to cooperate with the arc end of the rectangular push plate 58 to limit the safety pin, so as to ensure that the safety pin is correctly aligned with the jack on the handle of the fire extinguisher.

[0062] A linkage member 62 is provided between the U-shaped block 61 and the rectangular push plate 58. During the process of starting the second electric push rod 57 to drive the rectangular push plate 58 to move, the U-shaped block 61 is first driven to move along with the rectangular push plate 58. After the safety pin is inserted into the jack on the handle, the U-shaped block 61 is driven to move downward and retract to avoid the safety pin, so that the rectangular push plate 58 and the rectangular support plate 59 can be smoothly reset.

[0063] The linkage member 62 includes a first sliding sleeve 63 fixedly connected to the electric push rod. A round rod 64 is slidably connected to the first sliding sleeve 63. One side of the rectangular push plate 58 is fixedly connected with a second sliding sleeve 65, and one side of the rectangular support plate 59 is fixedly connected with a third sliding sleeve 66. One end of the round rod 64 sequentially passes through the second sliding sleeve 65 and the third sliding sleeve 66, and a first spring 67 with two ends respectively contacting and abutting against the second sliding sleeve 65 and the third sliding sleeve 66 is sleeved on the round rod 64, which is used to push the rectangular support plate 59 to move by using the first spring 67 when moving the rectangular push plate 58.

[0064] A limit convex 68 is fixedly connected to one end of the round rod 64. A third connecting rod 69 is rotatably connected between the other end of the round rod 64 and the U-shaped block 61 through a rotating shaft. An L-shaped stop block 71 is fixedly connected to the bottom end of the rectangular support plate 59, and a second spring 73 is sleeved on the round rod 64, and two ends of the second spring 73 are respectively fixed to the round rod 64 and the third sliding sleeve 66.

[0065] Specifically, after the fire extinguisher is inflated, the handle is deflected and opened by rotating the deflecting plate 8, and at the same time, the jack on the handle is aligned. Then, the second electric push rod 57 is started to drive the rectangular push plate 58 to move, and at the same time, the rectangular support plate 59 is pushed to move synchronously by using the first spring 67, so as to drive the safety pin on the rectangular support plate 59 to move and insert into the jack. During this process, the cooperation between the U-shaped block 61 and the arc end of the rectangular push plate 58 is used to ensure that the safety pin will not deviate, so as to ensure that the safety pin is smoothly inserted into the jack. Subsequently, the limit convex 68 contacts the first sliding sleeve 63 to block the continuous movement of the round rod 64. At this time, the rectangular push plate 58 continues to push the rectangular support plate 59 to move by using the first spring 67, so as to drive the U-shaped block 61 to move relative to the round rod 64, thereby pulling the U-shaped block 61 to move downward to avoid the safety pin by using the third connecting rod 69. At the same time, the second spring 73 is compressed and contracted to provide a self-restoring elastic force for the reset of the U-shaped block 61. Subsequently, since the U-shaped block 61 is blocked by the L-shaped stop block 71, it cannot move. At this time, the rectangular support plate 59 is locked, and then the rectangular push plate 58 is continuously moved, and it will move relative to the rectangular support plate 59 to completely insert the safety pin into the handle, and at the same time, the first spring 67 is compressed to provide a self-restoring elastic force for it. Subsequently, the second electric push rod 57 is reset, driving the rectangular push plate 58 and the rectangular support plate 59 to disengage from the safety pin inserted into the handle.

[0066] The end of the round roller 54 is designed with an inclined surface, which is convenient for embedding into the handle of the fire extinguisher.

[0067] Embodiment 2: Please refer to Figures 1-8, the present invention provides a technical solution: Embodiment 2 is optimized based on Embodiment 1;

[0068] The storage box 6 is detachably connected to the outer shell 1. Specifically, a support plate is fixedly connected to the outer shell 1, and a chute with a T-shaped cross-section is provided on the support plate. A sliding convex with a T-shaped cross-section is fixedly connected to the outer wall of the storage box 6. One end of the sliding convex is located in the chute and is slidably connected to its inner wall for connecting the storage box 6. After the safety pins in the storage box 6 are used up, the storage box 6 can be disassembled for filling, which is relatively convenient.
