Description

Technical Field

[0001] The invention relates to the technical field of installation equipment, in particular to an installation device for a fire extinguisher valve stem and an installation method thereof. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. Chemicals are placed in the fire extinguisher to put out fires. Fire extinguishers are one of the most common firefighting equipment and are stored in public places or places where fires may occur. During the production process of a fire extinguisher, the valve handle is usually assembled, and then the valve stem and return spring are installed in the valve and fixed by a stopper to complete the installation of the valve. Then, the fire extinguishing agent is filled into the fire extinguisher cylinder, and then the installed valve is fixed on the cylinder to complete the production of the fire extinguisher.

[0003] Publication No. CN210255924U discloses a device for installing a valve stem of a fire extinguisher. The problem raised in its background technology is: the defects of the prior art are that the structure is relatively complex and the structure cannot work fully automatically. There is no monitoring system for each process and the accuracy is poor. The valve stem is automatically installed by moving slide rails and manipulators, and monitored by a monitoring head. The process is simple, the error probability is low, each step of the process is ensured to be implemented accurately, and the work is fully automated, which greatly reduces the labor cost.

[0004] Based on the existing technology, there are the following problems:

[0005] When the existing fire extinguisher valve stem installation equipment is in operation, the valve stem is usually placed in the valve, then transferred to the downward position, the return spring is placed in the valve, and finally transferred to the next position to fix the stopper. After the valve stem and the return spring are placed in the valve in succession, no limiting mechanism is set for the valve stem and the return spring during the process of transferring the valve, which causes the valve stem and the limit spring to deviate or fall off during the process of transferring to the next position, affecting the stability of the installation, thereby affecting the stability of the fire extinguisher after it is actually put into use, and it is not convenient to install and use valve stems of different models and sizes.

[0038] The present invention also provides a method for installing a fire extinguisher valve stem installation device. Using the fire extinguisher valve stem installation device, the method comprises the following steps:

[0039] S1: The valve is fixed in the mounting frame by a clamping mechanism so that the valve is transported by a conveyor. During the transportation process, the valve stem is first placed in the valve, and then the valve with the valve stem is transported;

[0040] S2: When the valve with the valve stem is successively transmitted to the bottom of the spring placement mechanism and the stopper installation mechanism, the transmission is stopped, and the reset spring and the installation stopper are successively placed to complete the installation of the valve stem. During this process, the reset spring and the valve stem are limited by the limiting mechanism to prevent them from tilting or falling.

[0041] The present invention provides a fire extinguisher valve stem mounting device and a mounting method thereof. Compared with the prior art, the present invention has the following beneficial effects:

[0042] 1. The present invention cooperates with a limiting mechanism and a pushing mechanism, and after the valve stem and the return spring are placed in the valve, it is convenient to limit the valve stem and the return spring, so as to avoid the return spring and the valve stem from being offset when the stopper is subsequently installed, thereby ensuring the stability of the valve stem installation, thereby avoiding affecting the stability of the subsequent use of the fire extinguisher. The limiting mechanism and the pushing mechanism cooperate to facilitate the limiting of the valve stem and the return spring, and do not affect the installation of the return spring and the stopper. The limiting mechanism and the pushing mechanism can be adjusted, so it is convenient to use valve stems of different models and sizes.

[0043] 2. The present invention generates a repulsive force on the side where the first electromagnet and the second electromagnet are close to each other to drive the limit rod to move downward. At the same time, under the action of the first spring and the first limit ring, the limit rods are always close to each other, so that the bottom of the limit rod is inserted into the valve to limit the valve stem and avoid the valve stem from being offset during the conveying process. In addition, by setting a limit groove, it is convenient to limit the reset spring. When placing the spring and installing the stopper, the limit rod is first moved up by the first adjusting component, and then the limit rod is pushed open by the pushing mechanism, which is convenient for actually placing the reset spring and installing the stopper.

[0044] 3. The first adjusting component is used to facilitate adjustment of the downward movement distance of the limit piece and the limit rod. The first nut is set to limit the horizontal movement distance of the limit rod, thereby adjusting the length of the limit rod close to the valve, and the horizontal position of the connecting piece is adjusted by the second threaded rod of the pushing mechanism to be suitable for valve stems of different sizes. The position of the identification block and the scale groove relative to the connecting piece is grasped, so as to facilitate the position of the push plates on both sides of the first electric push rod to ensure the accuracy of the adjustment.

[0045] 4. The present invention clamps and fixes the valve by combining the clamping mechanism with the structure of the valve itself, thereby improving the stability of the clamping. The position of the second nut on the side wall of the third threaded rod is adjusted to limit the moving distance of the third threaded rod, thereby limiting the moving distance of the abutment plate and the clamping plate, so as to clamp and fix valves of different sizes. The second nut is elastically supported by the fourth spring and the second baffle to ensure the stability of the second nut.

[0046] 5. The present invention uses a positioning assembly so that when the valve is placed, the valve squeezes the positioning plate until the third nut contacts the frame. At this time, the positioning plate cannot move further, thereby limiting the placement position of the valve, which is convenient for subsequent limiting, etc., and the third nut is rotated on the side wall of the fourth threaded rod to adjust the position of the third nut, so that it is suitable for valves of different sizes. When the valve stem is installed, the seventh electromagnet and the eighth electromagnet generate repulsive force to drive the positioning plate to move, thereby pushing the valve out, which is convenient for removing the installed valve and facilitating the next installation and use.

[0080] See also Fig.11 and Fig.12 , the driving agency 5 includes:

[0081] The mounting frame 57 is fixedly arranged on the side wall of the telescopic shaft of the first electric push rod, and is symmetrical with the center point of the telescopic shaft of the first electric push rod. The inner wall of the mounting frame 57 is slidably provided with a horizontally movable connecting member 51, and the top of the connecting member 51 is sleeved with a vertically movable push plate 55, and the lower end of the push plate 55 is designed to be bent inward, and the bottom of the push plate 55 is designed to be arc-shaped to match the bending part of the limit rod 447 to smoothly push the limit rod 447, and the top of the push plate 55 is fixedly provided with a first baffle 52, and the side wall of the push plate 55 and between the connecting member 51 and the first baffle 52 are sleeved with a third spring, and the two ends of the third spring are respectively fixedly connected to the connecting member 51 and the first baffle 52 to elastically pull the first baffle 52, thereby limiting the position of the push plate 55.

[0082] The driving mechanism 5 also includes:

[0083] The second threaded rod 53 is threadedly connected to the outside of the installation frame 57 and extends into the installation frame 57. One end of the second threaded rod 53 located in the installation frame 57 is rotatably connected to the connecting member 51.

[0084] The scale plate 56 is fixed on the top of the mounting frame 57 , and the side wall of the connector 51 is fixed with an identification block 54 extending to the top of the scale plate 56 , with the tip of the identification block 54 pointing to the scale plate 56 to grasp the position of the symmetrically arranged push plate 55 .

[0085] In the specific implementation, the valve 8 is fixed to the inner side of the frame 422 by the clamping mechanism 45, and then the valve stem is placed in the valve 8 by the staff or the mechanical arm. After the valve stem is placed, the first electromagnet 445 and the second electromagnet 444 are started, so that the first electromagnet 445 and the second electromagnet 444 are close to each other and a repulsive force is generated to drive the second electromagnet 444, the limiter 443 and the limiter rod 447 to move downward, and at the same time, under the action of the first spring and the first limit ring 446, the valve stem 8 is placed in the valve 8. The limiting rod 447 is always close to each other, so that the bottom of the limiting rod 447 is inserted into the valve 8 to limit the valve stem to prevent the valve stem from deflecting during the conveying process. Then, the valve 8 with the valve stem is conveyed to the bottom of the spring placement mechanism 6 by the conveyor 3, and then the conveying is stopped. The first electromagnet 445 and the second electromagnet 444 are powered off first, and then the limiting member 443 and the limiting rod 447 are driven to move upward by the first adjusting component 449, so that the bottom of the limiting rod 447 is located at the valve. The top of the door 8, then, the spring placement assembly and the pushing mechanism 5 are driven downward by the first electric push rod. During this process, the push plate 55 of the pushing mechanism 5 first contacts the bending part of the limit rod 447 and squeezes the limit rod 447, so that the limit rod 447 squeezes the first spring to move away from the valve 8. As the push plate 55 continues to move downward, the bottom of the push plate 55 contacts the top of the valve 8 to overcome the traction of the third spring and move the push plate 55 upward. Then, the reset spring is placed in the valve 8 through the spring placement assembly. After the reset spring is placed, the first electric push rod drives the spring placement assembly and the pushing mechanism 5 to move upward. During this process, under the action of the first spring, the limit rod 447 limits the reset spring through the limit groove 448. Then, the valve 8 equipped with the reset spring and the valve stem is moved to the bottom of the stopper installation mechanism 7 through the conveyor 3. Then, according to the steps of the above-mentioned spring placement mechanism 6, the stopper is installed in the valve 8 to install and fix the valve stem and the reset spring, that is, the installation of the valve stem is completed;

[0086] When the pushing mechanism 5 moves upward, under the action of the first spring and the third spring, the bending part of the limit rod 447 is always in contact with the bending part of the push plate 55 until the push plate 55 is separated from the limit rod 447. During this process, the push plate 55 is bent inward, so that the limit rod 447 gradually approaches the limit spring placed in the valve 8, so as to avoid the limit rod 447 and the limit spring suddenly contacting and squeezing each other under the action of the first spring, thereby affecting the stability of the limit, and making the push plate 55 bend inward and the limit rod 447 bend downward, so that the push plate 55 can push the limit rod 447 to move horizontally.

[0087] The inner side wall of the limiting groove 448 is designed to be arc-shaped to fit the outer side of the reset spring, and the top of the limiting groove 448 is designed to be flat to limit the top of the reset spring; the valve stem is pressed downward by the bottom of the limiting rod 447, and the reset spring is limited by the limiting groove 448;

[0088] By setting the first nut to limit the horizontal moving distance of the limiting rod 447, the length of the limiting rod 447 close to the valve 8 is adjusted to be suitable for valves 8 of different sizes, and by setting the second limiting ring 442 and the second spring, the first nut is elastically supported to ensure the stability of the first nut, thereby ensuring the stability of the adjustment;

[0089] By making the connecting member 51 move horizontally in the installation frame 57 and by the push plate 55 moving vertically along the connecting member 51, the push plate 55 pushes the limit rod 447 away, and the horizontal position of the connecting member 51 is adjusted by the second threaded rod 53, and cooperates with the limit mechanism 44 to be suitable for valve stems of different sizes. By mastering the position of the identification block 54 and the scale groove 4553 relative to the connecting member 51, it is convenient to master the position of the push plates 55 on both sides of the first electric push rod, so as to ensure the accuracy of adjustment and avoid affecting the actual use;

[0090] The first baffle 52 is pulled by the third spring, thereby pulling the push plate 55, so that the push plate 55 always has a downward tendency, and when the limit rod 447 is squeezed, the difference in elasticity between the first spring and the third spring can ensure that the push plate 55 stably pushes the limit rod 447 to move horizontally.

[0107] The scale groove 4553 is formed on the side wall of the third threaded rod 4552 to grasp the position of the second nut.

[0108] In a specific implementation, the third threaded rod 4552 moves along the side wall of the frame body 422 to limit the movement of the abutment plate 451. At the same time, the second nut is rotated to adjust the position of the second nut on the side wall of the third threaded rod 4552, thereby limiting the movement distance of the third threaded rod 4552, and then limiting the movement distance of the abutment plate 451 and the clamping plate 452, so as to clamp and fix valves 8 of different sizes.

[0109] The position of the second nut is marked by the graduated groove 4553 to facilitate the position of the clamping plates 452 on both sides of the frame 422 , thereby facilitating the centering and fixing of the valve 8 and facilitating subsequent limiting and the like.

[0110] Example 2: Please refer to Fig. 9 and Fig.10 The difference between this embodiment and the first embodiment is that the positioning component 43 includes:

[0111] The fourth threaded rod 432 is movably sleeved on the inner side of the frame 422 and extends outside the frame 422. A positioning plate 431 is fixedly provided at one end of the fourth threaded rod 432 located in the frame 422, which is used to limit the position of the valve 8. A third nut is threadedly connected to the side wall of one end of the fourth threaded rod 432 located in the frame 422, which is used to limit the position of the fourth threaded rod 432.

[0112] The positioning member 433 is fixed to one end of the fourth threaded rod 432 located outside the frame 422, and a rod body 435 is sleeved on the lower end of the side wall of the positioning member 433, and the rod body 435 is fixedly connected to the outer side of the frame 422, and a support plate is fixedly provided on the end of the rod body 435 away from the frame 422, and a seventh electromagnet 434 is fixedly provided on the side of the support plate close to the positioning member 433, and an eighth electromagnet 436 is fixedly provided on the side of the positioning member 433 close to the seventh electromagnet 434, and the eighth electromagnet 436 and the seventh electromagnet 434 are both sleeved on the side wall of the rod body 435, and the side where the eighth electromagnet 436 and the seventh electromagnet 434 are close to each other are the same poles, and a fifth spring is sleeved on the side wall of the rod body 435 and located between the positioning member 433 and the support plate, and the fifth spring is located on the outside of the seventh electromagnet 434 and the eighth electromagnet 436.

[0113] In the specific implementation, the positioning member 433 is elastically supported by the fifth spring, thereby elastically supporting the fourth threaded rod 432 and the positioning plate 431, and the third nut is used to limit the moving distance of the fourth threaded rod 432. When the valve 8 is placed, the valve 8 squeezes the positioning plate 431 until the third nut contacts the frame 422. At this time, the positioning plate 431 cannot move further, thereby limiting the placement position of the valve 8, which is convenient for subsequent limiting, etc., and the third nut is rotated on the side wall of the fourth threaded rod 432 to adjust the position of the third nut, so that it is suitable for valves 8 of different sizes. When the valve stem is installed, the clamping mechanism 45 cancels the clamping, and the seventh electromagnet 434 and the eighth electromagnet 436 generate repulsive force to drive the positioning plate 431 to move, thereby pushing the valve 8 out, which is convenient for removing the installed valve 8 and facilitating the next installation and use.

[0114] The clamping mechanism 45 also includes:

[0115] The positioning groove 453 is provided at the middle of the top of the clamping plate 452 to mark the position of the clamping valve 8 so as to facilitate the grasp of the placement position of the valve 8 .

[0116] The embodiment of the present invention further provides a method for installing a fire extinguisher valve stem installation device, using a fire extinguisher valve stem installation device, the method comprising the following steps:

[0117] S1: The valve 8 is fixed in the mounting frame 42 by the clamping mechanism 45 so that the valve 8 is transported by the conveyor 3. During the transport process, the valve stem is first placed in the valve 8, and then the valve 8 with the valve stem is transported;

[0118] S2: When the valve 8 with the valve stem is successively transmitted to the bottom of the spring placement mechanism 6 and the stopper installation mechanism 7, the transportation is stopped, and the reset spring and the installation stopper are successively placed to complete the installation of the valve stem. In this process, the reset spring and the valve stem are limited by the limiting mechanism 44 to prevent them from tilting or falling, thereby ensuring the accuracy of the installation and avoiding the situation that the valve stem cannot be used when it is actually put into use, so as to ensure the working stability of the fire extinguisher. When the valve 8 is clamped by the clamping mechanism 45, the positioning component 43 is used to assist in limiting the position of the clamping mechanism 45 to clamp the valve 8, so that the limiting rod 447 of the subsequent limiting mechanism 44 is located directly above the valve 8, thereby limiting the valve stem and the reset spring, and the positioning component 43 is used to facilitate the valve 8 to be pushed out from the inner side of the mounting frame 42 after the installation of the valve stem is completed, so as to facilitate the next installation;

[0119] After the valve stem is placed in the valve 8, the valve 8 equipped with the valve stem moves to the bottom of the spring placement mechanism 6, and then the transportation is stopped. Under the cooperation of the pushing mechanism 5 and the limiting mechanism 44, the limiting rod 447 is first moved out of the valve 8 to facilitate the placement of the reset spring in the valve 8. After the reset spring is placed, the limiting mechanism 44 limits the reset spring, and then the conveyor 3 continues to drive the valve 8 equipped with the valve stem and the reset spring to move to the bottom of the stopper installation mechanism 7, and then the transportation is stopped. The stopper is installed on the top of the valve 8 through the cooperation of the pushing mechanism 5 and the limiting mechanism 44 to install the valve stem and the reset spring, thereby completing the installation of the valve stem.
