Description

Technical Field

[0001] The utility model belongs to the technical field of fire extinguisher equipment manufacturing, and particularly relates to a fire extinguisher valve tightening device. Background Art

[0002] During the traditional installation process of fire extinguisher valves, a V-shaped clamp driven by a pneumatic cylinder is often used to secure the extinguisher barrel. The operator then needs to manually rotate the valve using a power lever to complete the tightening operation. This method has many problems: First, it is inefficient because the installation of each valve requires manual intervention, which leads to longer production cycles; second, it is labor-intensive, requiring operators to frequently perform repetitive physical labor, increasing labor intensity and potentially causing occupational injuries; and finally, the tightening torque is uncontrollable. The lack of precise torque control means that the valve may not be tightened enough, resulting in leakage, or it may be overtightened, generating strong stress, which may eventually damage or even break the valve, posing a serious safety hazard.

The above-mentioned device requires the valve tightening mechanism and the valve tightening tooling to be aligned during the valve tightening process in order to complete the valve tightening work. Therefore, it is urgent for those skilled in the art to solve the above technical problems. Utility Model Content

[0004] The technical problem to be solved by the present invention is that in the prior art, when the above-mentioned device is tightening the valve, it is necessary to align the valve tightening mechanism and the valve tightening tooling in order to tighten the valve, and any deviation needs to be corrected in time.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A fire extinguisher valve tightening device comprises a base, a transmission assembly, a tightening assembly and a positioning assembly; the transmission assembly is located above the base, a backing plate is provided on the right side of the base, the tightening assembly is fixed on the backing plate, the positioning assembly is provided on the left side of the base, the tightening assembly comprises a base, a movable arm, a rotating shaft and a bayonet end, the tightening assembly is fixed to the backing plate through the base, the movable arm is installed on the base, the rotating shaft is installed at the head end of the movable arm, the rotating shaft is connected to the bayonet end, the positioning assembly comprises a driving cylinder and a clamping claw, the clamping claw and the tightening assembly are on the same vertical plane.

[0007] Furthermore, sensors are provided on the bayonet end and the clamping claw, and the tightening assembly and the positioning assembly are both connected to an external power supply.

[0008] Sensors installed on the clamping end and the clamping jaws monitor the contact status, position deviation, and torque changes between the valve and clamping jaws in real time during the tightening process. This helps ensure precise alignment between the valve and clamping jaws and control torque during the tightening process. By monitoring torque with sensors, tightening torque can be precisely controlled, avoiding valve damage due to excessive torque or undertightening due to insufficient torque. The sensors send real-time data to the control system, which automatically adjusts the movements of the tightening and positioning components based on this data, achieving a higher degree of automation. Both the tightening and positioning components are connected to an external power supply, meaning they can be powered and controlled by the control system. This makes the entire tightening process more automated and efficient, reducing operational difficulty and labor intensity. Sensors detect valve position deviation and adjust the position of the clamping jaws through the control system, achieving automatic alignment and alleviating manual alignment work for the operator. Sensors on the clamping end monitor the tightening status of the valve. When the predetermined torque or angle is reached, the system automatically stops tightening, eliminating the need for manual judgment and reducing operational complexity. Through automated control and sensor assistance, the degree of human intervention is reduced.

[0009] Furthermore, a plurality of the tightening components and the positioning components are provided.

[0010] Multiple tightening components and positioning components can operate multiple fire extinguisher valves at the same time, thereby significantly improving production efficiency. By rationally arranging multiple tightening components and positioning components, an efficient assembly line production model can be constructed, making the entire production process smoother. The number of tightening components and positioning components can be flexibly increased or decreased according to changes in production needs to adapt to production tasks of different scales. Multiple tightening components and positioning components can work independently or collaboratively to facilitate the expansion and maintenance of the production line. Multiple components can ensure the continuous operation of the production line. Even if a component needs maintenance or replacement, other components can continue to work to ensure the continuity of production. Multiple tightening components and positioning components can evenly distribute the workload, avoid overloading of a single component, and improve the overall utilization of the equipment. Multiple components can automatically complete more operations, reduce the labor intensity of operators, and through the collaborative work of multiple components, the operating process can be simplified and the difficulty of operation can be reduced.

[0011] Furthermore, the driving cylinder includes a first driving cylinder and a second driving cylinder, the first driving cylinder is installed on the power supply cabinet on the right side of the base, and the second driving cylinder is installed inside the clamping claw; the clamping claw includes a positioning member, a connecting rod, a transmission rod and a support block, the second driving cylinder is connected to the support block, and connecting rods are provided at both ends of the support block, the connecting rod is hinged to the transmission rod, and the transmission rod is hinged to the positioning member.

[0012] The first drive cylinder can accurately control the position of the clamping claw, while the second drive cylinder is responsible for the execution of the clamping action. The two work together to improve the level of automation. Through the movement of the first drive cylinder and the clamping action of the second drive cylinder, automated operation can be achieved, reducing manual intervention. The positioning part can ensure that the fire extinguisher cylinder is aligned with the tightening component, thereby achieving precise valve tightening operation. Through the linkage mechanism of the connecting rod and the transmission rod, the various parts of the clamping claw can be ensured to move synchronously, improving the alignment accuracy. The second drive cylinder is installed inside the clamping claw, reducing additional external components and making the overall structure more compact. The design of the connecting rod, transmission rod and support block makes maintenance simpler and more convenient. The automatic clamping of the clamping claw reduces the manual operation of the operator and reduces labor intensity. The use of positioning parts reduces the difficulty of alignment and reduces the difficulty of operation. Multiple clamping claws can clamp multiple fire extinguisher cylinders at the same time, speeding up the production process. Through automated control, continuous production can be achieved and production efficiency can be improved.

[0013] Furthermore, the positioning member includes a first positioning member and a second positioning member, and the first positioning member and the second positioning member clamp the fire extinguisher under the action of the driving cylinder.

[0014] The positioning piece can firmly fix the fire extinguisher to ensure that it will not move during the tightening process, thereby improving the stability of the entire device. The tight fit reduces the vibration of the fire extinguisher during the tightening process and improves the tightening quality. The positioning hole can make the fire extinguisher evenly stressed, avoiding tightening quality problems caused by local uneven force. The tight fit reduces the risk of valve damage caused by shaking. The cooperation of the first positioning piece and the second positioning piece can quickly realize the positioning of the fire extinguisher, speed up the production process and improve production efficiency. The design of the positioning hole helps to realize automated operation and reduce the difficulty of operation.

[0015] Furthermore, the base is fixed to the back plate by bolts, the rotating shaft is driven by a built-in driving motor, the bayonet end includes a limit baffle and an electromagnet, and the electromagnet is provided on the inner side of the limit baffle.

[0016] The base is fixed to the back plate by bolts, which ensures the stability of the entire tightening assembly and reduces shaking during operation. The built-in drive motor directly drives the rotating shaft, reducing the use of transmission components and improving the stability and reliability of the system. The built-in drive motor can achieve precise torque and angle control, improving the level of automation. The valve can be automatically grasped and released by the electromagnet, reducing manual intervention. The built-in drive motor can accurately control the torque during the tightening process, ensuring that the valve is tightened to the appropriate position without damaging the valve. The built-in drive motor can also control the rotation angle to ensure that the valve is tightened to the correct angle. The design of the built-in drive motor reduces external transmission components, making the structure more compact. The electromagnet adsorption valve simplifies the design of the bayonet end and reduces the complex mechanical structure.

[0030] During use, the staff places the fire extinguisher on the conveying component 2, and the conveying component 2 transports the fire extinguisher to be tightened to the designated position. The driving cylinder 41 in the positioning component 4 drives the clamping claw 42 to move, so that the clamping claw fixes the fire extinguisher to ensure that the valve 5 is aligned with the tightening component 3. The tightening component 3 drives the rotating shaft 33 through the movable arm 32. The bayonet end 34 at the front end of the rotating shaft 33 aligns the fixed valve 5 with the fire extinguisher. The valve 5 rotates under the drive of the rotating shaft 33 to tighten the valve 5. The bayonet end 34 grabs the valve 5 and tightens it according to the set torque or angle. After tightening is completed, the positioning component 4 releases the fire extinguisher cylinder, and the conveying component 2 moves the fire extinguisher out.

[0031] Embodiment 2: Compared with embodiment 1, embodiment 2 can enhance the degree of automation of the positioning component 4 and the tightening component 3. The positioning component 4 and the tightening component 3 are driven by an external power supply. A proximity sensor is set on the clamping claw 42. When the fire extinguisher passes through the clamping claw 42, the proximity sensor detects the fire extinguisher and controls the clamping claw 42 to fix the fire extinguisher. A torque sensor and a proximity sensor are installed on the bayonet end 34. After the fire extinguisher is positioned by the positioning component 4, the movable arm 32 and the bayonet end 34 bring the valve 5 to the top of the fire extinguisher. The rotating shaft 33 rotates according to the setting requirements, thereby driving the bayonet end 34 and the valve 5 to rotate, and finally completing the installation of the valve 5, thereby improving the degree of automation and tightening quality of the tightening device, while reducing the operator's workload and potential safety hazards.

[0032] Example 3: Compared with Example 1 and Example 2, in order to further improve the working efficiency of the device, two tightening devices 3 are installed on the back plate 11. At the same time, two positioning devices 4 are also installed on the left side of the base 1. During production and processing, the fire extinguisher to be processed is first placed at the head end of the conveying component 2. Then, another fire extinguisher to be processed is placed between the two positioning components 4. The valves 5 of the two fire extinguishers can be tightened and installed at the same time, which improves the working efficiency. The fire extinguishers are placed at different positions of the conveying component 2 to avoid possible interference between the two sets of positioning components 4 and the two sets of tightening components 3.

[0033] Example 4: When the positioning assembly 4 clamps the fire extinguisher to be processed, in order to further improve the clamping and positioning efficiency of the fire extinguisher, refer to Figure 1 、 Figure 2 、 Figure 4 and Figure 5 It can be seen that the first driving cylinder 411 of the positioning component 4 is installed on the power supply cabinet 12, which is used to control the clamping claw 42 to approach the fire extinguisher and move away from the fire extinguisher after processing. The second driving cylinder 412 is installed in the clamping claw 42. The top of the second driving pneumatic 412 is connected to the support block 424. The two ends of the support block 424 are hinged with connecting rods 422. The connecting rod 422 is hinged to the transmission rod 423. At the same time, the transmission rod 423 is hinged to the positioning member 421. The second driving cylinder 412 drives the positioning member 421 to clamp the fire extinguisher to be processed. Through the above structure, the fire extinguisher can be well positioned at the position of the positioning component 4, which is convenient for the tightening operation of the tightening component 3.

[0034] Example 5: In order to ensure that the fire extinguisher does not slip when the tightening assembly 3 tightens the valve 5 on the fire extinguisher, the first positioning member 4211 and the second positioning member 4212 of the positioning member 421 clamp the fire extinguisher under the action of the driving cylinder 41, so that when the tightening assembly 3 is working, the positioning member 421 can stably position the fire extinguisher on the transmission assembly 2. After the positioning assembly 4 clamps the fire extinguisher, the transmission assembly 2 stops working under the control of the sensor signal and the controller. The above steps can ensure the stability of the fire extinguisher valve 5 during installation.

[0035] Example 6: In order to facilitate the stability of the valve 5 at the bayonet end, refer to Figure 3 It can be seen that a limit baffle 341 is installed on the bayonet end 34, and an electromagnet is installed on the inner wall of the limit baffle 341. The valve 5 is fixed in the bayonet end 34 under the action of the limit baffle 341 and the electromagnet. After the tightening is completed, the electromagnet is powered off, and the bayonet end 34 moves away from the top of the fire extinguisher under the drive of the movable arm 32. The positioning component 4 releases and retracts the clamping claw 42, and the conveying component 2 starts to move the fire extinguisher to the designated area.

[0036] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various equivalent transformations can be made to the technical solutions of the present invention, and these equivalent transformations all fall within the scope of protection of the present invention.
