Description

Technical Field

[0001] The invention relates to the technical field of test devices for fire extinguisher valves, in particular to an impact resistance test device for fire extinguisher valves. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. It contains chemicals that are used to put out fires. When used, the compressed or liquefied gas in the extinguisher will eject the extinguishing agent (such as dry powder, foam, carbon dioxide, etc.) in the cylinder, interrupting the fire.

[0003] The fire extinguisher valve is an important component of the fire extinguisher. It controls the release of the fire extinguishing agent. The fire extinguisher valve needs to undergo various tests when the fire extinguisher is processed and produced. Among them, the impact test is an indispensable part. In the existing technology, the fire extinguisher is usually fixed and the valve is placed at the bottom of the weight. The weight is driven up by the equipment and then discarded, thereby impacting the outside of the valve to test the impact resistance of the valve. However, the interior of the fire extinguisher is usually equipped with gas. When the valve is damaged, the internal gas will be discharged, causing damage to the testing environment. At the same time, the counterweight block may pop out when falling, causing impact damage to the staff in the testing environment. Summary of the Invention

[0048] The piston rod 62 can be resisted by the flipper 32 and move inside the bent pipe 61. By utilizing the principle of piston movement, the movable plug 65 is driven by pressure to move, and at the same time, the hollow block 67 and the trapezoidal block 68 are driven to move. The trapezoidal block 68 is inserted into the slot 51 to limit the protective tube 5, and the hollow block 67 resists the opening block 71 to move, completing the transmission of the entire device.

[0049] See also Figure 9 and Figure 10 as well as Figure 11 The bent pipe 61 can guide the piston rod 62 and the movable plug 65, the piston rod 62 can drive the movable plug 65 to move, and the movable plug 65 can be clamped into the internal limiting protective tube 5 of the card slot 51 through the hollow block 67 and the trapezoidal block 68 to move. The cooperation of the trapezoidal block 68 and the hollow block 67 can only affect the rise of the protective tube 5, and cannot affect the descent of the protective tube 5.

[0050] The outside of the hollow column 41 is slidably equipped with a protective tube 5, and the outside of the protective tube 5 is evenly distributed with card slots 51. The outside of the protective tube 5 is equipped with a locking mechanism 7, which includes an opening block 71 and a second triangular block 74. Both sides of the opening block 71 are connected to a cross arm 72. The end of the cross arm 72 close to the hollow column 41 is connected to the first triangular block 73. The second triangular block 74 is inserted into the inside of the protective tube 5, and a fourth spring 75 is connected between the second triangular block 74 and the protective tube 5.

[0051] The opening block 71 can be driven by the hollow block 67, which in turn drives the cross arm 72 to move, and then drives the second triangular block 74 to move through the first triangular block 73, thereby restricting the feeding mechanism 3 and the limiting mechanism 6.

[0052] The temperature control box 21 and the KK module 31 are both connected to the test bench 1, and the outside of the hollow column 41 is connected to the test bench 1 through the stand 64. The inner side of the stand 64 is connected to the elbow 61. The temperature control box 21 is provided with a slot at one end close to the feeding mechanism 3, and the inner cavity of the slot is equipped with a sensing door 24. The outside of the temperature control box 21 is equipped with a control console. The slot facilitates the assembly of the sensing door 24. At the same time, the inner side of the sensing door 24 is equipped with a sensor. The sensor can sense the fire extinguisher and then drive the sensing door 24 to rise and fall. The sensing door 24 is a common lifting sensing device in the prior art.

[0053] Both sides of the top of the test bench 1 are provided with a track groove 11, and the internal sliding connection of the track groove 11 is connected to the track slider 35, and the track slider 35 is connected to the flipper 32. The track groove 11 cooperates with the track slider 35 to guide the flipper 32 so that it can move in a straight line. At the same time, it can support the flipper 32 to prevent the fire extinguisher from being damaged when it is impacted. The outside of the movable plug 65 is connected to a second spring 66, and the second spring 66 is connected to the inner cavity of the bent pipe 61. The second spring 66 can increase the reaction speed and return speed of the movable plug 65 when it is driven by the piston rod 62 through negative pressure.

[0054] There are at least twelve groups of slots 51, and the slots 51 fit together with the trapezoidal blocks 68. The slots 51 can be inserted into and limited by the trapezoidal blocks 68. The outside of the cross arm 72 is connected with a sliding block 76, and the outside of the sliding block 76 is slidably connected with a slotted block 77. The slotted block 77 is connected to the protective tube 5. A fifth spring 78 is connected between the sliding block 76 and the slotted block 77. The sliding block 76 cooperates with the slotted block 77 to guide the cross arm 72 so that it can move in a straight line. The fifth spring 78 can make the cross arm 72 and the hole block 71 return to their original positions after the movement is completed.

[0055] The interior of the protective tube 5 is provided with a track groove that is compatible with the fourth spring 75, and the track groove is connected to the fourth spring 75. The track groove can guide and accommodate the fourth spring 75. Vertical grooves 47 are provided on both sides of the exterior of the hollow column 41. Scale lines 48 are connected to both sides of the vertical groove 47. A pointer 46 is slidably connected to the interior of the vertical groove 47, and the pointer 46 is connected to the electromagnet 44. The vertical groove 47 and the scale line 48 can improve the stability of the electromagnet 44 during movement, and can calculate the position height of the electromagnet 44, thereby determining the falling height of the weight block 45.

[0056] This solution first places the fire extinguisher into the temperature control box 21, starts the temperature control box 21 to store the fire extinguisher at the lowest operating temperature for 18 hours, and then starts the first hydraulic cylinder 22 to drive the push plate 23 to push the fire extinguisher to move. When the fire extinguisher moves to the outside of the sensing door 24, the sensing door 24 is sensed and the sensing door 24 rises. The fire extinguisher is pushed to the turning platform at the top of the flipper 32 and is fixed by the pressing plate 34 and the second hydraulic cylinder 33. The KK module 31 drives the flipper 32 to move to the bottom of the hollow column 41, pulling the protective tube 5 down. , sleeved on the outside of the valve, at this time the flipper 32 moves again to resist the movement of the piston rod 62, and then drives the trapezoidal block 68 to insert into the inside of the card slot 51, locking the position of the protection tube 5, and driving the opening block 71 to drive the cross arm 72 to move, and then through the first triangular block 73 to drive the second triangular block 74 and the fourth spring 75 to pop out from the inside of the protection tube 5, stuck on the outside of the pressure plate 34, and protect and support the weight block 45, the electromagnet 44 releases the fixation of the weight block 45, and the weight block 45 descends to impact the valve body of the fire extinguisher, and performs an impact test on it;

[0057] During operation, the fire extinguisher is fixed horizontally inside the reverser, and the fire extinguisher is driven to move as a whole by the flipper 32. The flipper 32 can be flipped 90 degrees, and then the valve body of the fire extinguisher can be subjected to a secondary impact test. The protective cover is set on the outside of the entire flipper 32, that is, the entire fire extinguisher is protected. Since the volume of the protective cover is larger than the volume of the fire extinguisher, the fire extinguisher can be directly flipped inside the protective cover. At the same time, the volume of the weight block 45 is larger than the area of ​​the valve body, which results in the fire extinguisher being able to perform an impact test on the valve body after the flip is completed.

[0058] The flipper 32 is divided into two parts, one is the base part connected to the KK module 31, and the other is the internal flipping part. It is the base part that drives the piston rod 62 to move, that is, the flipping part will not affect the resistance drive of the piston rod 62 after the flipping is completed.

[0059] The fire extinguisher can be fed and cooled fully automatically by the added push plate 23, the first hydraulic cylinder 22, the flipper 32, the second hydraulic cylinder 33 and the pressure plate 34. The flipper 32 can be flipped 90 degrees to allow the valve of the fire extinguisher to receive side and top impacts, thereby supplementing the impact test data and improving the accuracy of the data. At the same time, the added protective tube 5 automatically shields the outside of the valve when the valve is subjected to an impact test, thereby preventing the valve from damaging the gas inside the fire extinguisher and discharging the gas, and preventing the weight block 45 from popping out and causing injuries to the staff.

[0060] When the feeding mechanism 3 drives the fire extinguisher to move, it automatically drives the limiting mechanism 6 to move, thereby fixing the position of the protective tube 5 to prevent the protective tube 5 from shaking during use, thereby reducing the protection effect of the valve;

[0061] When the limiting mechanism 6 is driven, it transmits the locking mechanism 7, so that the second triangular block 74 pops out from the inside of the protective tube 5, limiting the position of the feeding mechanism 3, and preventing the feeding mechanism 3 from shaking when the valve is being tested, causing the valve to be unable to be normally impacted. At the same time, it can support the falling weight block 45, thereby facilitating the winch 43 to drive the electromagnet 44 to descend and recover the weight block 45, thereby greatly improving the overall operation speed of the device.
