Description

Technical Field

[0001] The present invention relates to the technical field of the production and manufacturing of gas metering instrument equipment, and in particular to a highly automated and intelligent flow-type detection device for detecting the pressure resistance and deformation performance of household or industrial gas meters. Background Art

[0002] Gas meters measure flammable and explosive gases. Once there is a gas leak due to quality problems, it will cause serious safety hazards. Therefore, strict detection to ensure the safety performance of gas meters is crucial.

[0003] Currently, the pressure resistance test of gas meters mainly adopts the gas static detection method, that is, applying gas with 1.5 times the rated pressure inside the gas meter, maintaining the pressure for 30 minutes, and checking the deformation amount. However, this method has a large difference from the actual use situation of gas meters. In actual situations, the gas pressure in the gas pipeline and inside the meter will constantly change, and the periodic fluctuation of the internal pressure will cause fatigue stress, thereby reducing the strength of the gas meter and posing a leakage hazard. And the existing static detection process cannot effectively test the anti-fatigue ability of gas meters and is difficult to truly evaluate their safety and reliability.

[0004] To solve this problem, some dynamic test schemes have been proposed in the prior art. For example, the authorized publication number CN217688309U discloses a gas meter pressure resistance strength test device, which can simulate the process of the fatigue stress of the meter body caused by the continuous change of the internal pressure of the gas meter, and detect the anti-fatigue strength of the gas meter by accelerating the simulation. Another authorized publication number CN220399154U discloses a multi-functional detection device for gas meters, which integrates multiple test functions such as bending moment, torque, and pressure resistance, and has a simple and reliable structure.

[0005] Although the above technical solutions have certain innovations, there are still some deficiencies in actual applications. First, most of the current gas meter pressure resistance test processes require manual operation, resulting in low efficiency. The test of each gas meter takes about 40 minutes, and the interface between the gas pipe and the meter to be tested needs to be manually tightened and connected, with cumbersome operations. This is because most of the existing equipment fails to truly achieve automation, and many links in the detection process still require manual participation, such as installing and fixing the meter to be tested, connecting the gas source pipeline, adjusting the air pressure, monitoring data, etc., bringing heavy labor intensity to the staff.

[0006] In addition, since the gas meter detection requires extremely high sealing tightness, simple connection methods such as quick connectors cannot be used for the interface between the gas pipe and the meter under test. Instead, it must be connected by manually tightening the threads. At the same time, to ensure the accuracy of the test mechanism, its gas source interface is usually fixedly set and cannot be adjusted. Therefore, when manually tightening the connection, it is necessary to repeatedly and alternately turn the two interfaces to avoid insufficient screwing, jamming, or damage to the threads on one side due to excessive tightening on the other side. It can be seen that the traditional manual tightening method brings a large number of long and cumbersome processes to the interface connection process. Summary of the Invention

[0054] Specific technical solution

[0055] Embodiment 1

[0056] Refer to the attached Figure 1-8 , a gas meter pressure-resistant deformation flow-type automatic detection device, including a frame part 1 with an upper, middle and lower three-layer structure that divides the entire device into different functional areas, an integrated detection device 2 for performing pressure application on the gas meter, detecting the deformation of the meter body and a series of other data collection and processing such as pressure monitoring and sealing inspection, and a conveying device 3 for conveying the gas meter in cooperation with the integrated detection device 2. Among them, the installation position of the integrated detection device 2 is in the middle layer and the upper layer of the frame part 1, and the conveying device 3 is in the middle layer of the frame part 1.

[0057] The integrated detection device 2 is an advanced gas meter test system, which is designed to comprehensively evaluate the performance and pressure resistance of the gas meter. This system at least includes three main components:

[0058] 1. Gas source component 21: This core component is responsible for simulating the actual gas flow in the gas meter and can apply a pressure 1.5 times the normal operating pressure to the inside of the gas meter. This can be achieved through a precisely controlled pressure regulation system, which ensures that the gas meter can be tested under safe control conditions to its extreme operating conditions.

[0059] 2. Measuring component 22: In order to detect the physical deformation of the gas meter housing under high pressure, the measuring component 22 includes displacement sensors 221, which are used to monitor the minute changes in the housing. These sensors can accurately record any shape changes, thus providing key data for analysis to ensure that the gas meter maintains its structural integrity when subjected to high gas pressure.

[0060] 3. Data acquisition and processing unit: There is at least one such unit to collect data from the gas source component 21 and the measuring component 22 and analyze it to evaluate the performance and safety of the gas meter under high pressure conditions. This unit usually includes a high-speed processor and storage devices, which can process data in real time and provide output results that are easy for users to understand.

[0061] To improve the integration and operation efficiency of the entire system, the data acquisition and processing unit and the gas source component 21 that simulates gas flow are integrated within a designed housing 23. This design not only helps reduce external interference but also makes maintenance and upgrading more convenient.

[0062] In addition, the entire housing 23 together with these internal components is installed on the upper layer of the frame part 1, which is conducive to ensuring the stability and long-term reliable use of the equipment. This layout also facilitates technicians' access to and maintenance of each component while maintaining the compactness and industrial aesthetics of the entire system.

[0063] In the gas source component 21, in addition to undertaking the core functions of simulating gas flow and applying operating pressure, it also includes an interface module 211 that automatically makes threaded connections with the two interfaces of the gas meter. The design of this interface module 211 aims to achieve fast, accurate, and reliable connections with the input and output ports of the gas meter.

[0064] The interface module 211 is a key component in the integrated detection device 2. It has automatic alignment and threaded connection functions to ensure precise fit with the gas meter interface during the test. This module also has excellent sealing performance to prevent leakage at the connection points during the test and guarantee the accuracy of the test results. The interface module 211 includes the following parts:

[0065] 1) Fixed track 201: This component is firmly installed on the lower bottom surface of the upper layer of the frame part 1, providing stable support and guiding the movement of the slide block 202.

[0066] 2) Slide base 202: These two slide bases can slide freely on the fixed track 201 and be locked, providing flexibility and adjustability for the subsequent connection process.

[0067] 3) Actuator mounting frame 203: It is fixedly connected to the lower part of each slide base 202 through a fixing block or the cylinder body. It defines an internal space to install the components for performing the connection. In the vertical direction, the corresponding slide base 202 and the actuator mounting frame 203 form a group, and two groups correspond to the two interfaces of the gas meter to be measured.

[0068] 4) Connector 204: It is arranged on the side surfaces of the two actuator mounting frames. This component ensures that the two frames are strictly aligned and connects them into one body. The design of the connector 204 also ensures the equidistant positioning of the center distance between the actuator mounting frames and the centers of the two interfaces of the gas meter.

[0069] 5) Docking joint 205: These joints are arranged inside each actuator mounting frame 203 and are used for direct connection with the interfaces of the gas meter. The directly contacting part of the docking uses a flexible material with a certain strength, such as rubber. This material can adapt to slight position deviations and provide good sealing performance.

[0070] 6) Automatic tightening assembly 206: Its execution part is arranged below the two docking joints 205, while the power and torque adjustment parts are arranged on the connector 204. The automatic tightening assembly 206 is responsible for accurately tightening and loosening the threads to ensure the firmness and tightness of the connection.

[0071] Summary of the working process of the interface module 211: Through the rotational movement of the automatic tightening assembly 206, it is accurately thread-connected to the port of the gas meter until the port is closely fitted with the docking joint 205. The automatic tightening assembly 206 adjusts the appropriate torque according to the preset program to ensure the firmness of the connection.

[0072] The automatic tightening assembly 206 can select a mature mechanism or a combination of mechanisms in the existing technology. For example: an intelligent tightening robot. This kind of robot can accurately control the rotational movement and tightening torque of the screw to ensure the reliability of the connection. They are usually equipped with advanced sensors and controllers and can work efficiently in complex environments. However, intelligent tightening robots also have their limitations. Due to their complex structure, their manufacturing cost and maintenance cost are usually high. In addition, if used to connect the two interfaces of the gas meter, the intelligent tightening robot needs to design two independent drive systems, which involves the issue of synchronization.

[0073] Therefore, the automatic spiral tightening assembly 206 is optimized to ensure its more smooth and efficient collaborative work with the two actuator mounting frames 203. Refer to Figure 4-7, These figures detail the overall structure of the component and its connection to the framework.

[0074] Figure 4 It shows the overall picture of the overall structure, clearly presenting the positions and connection methods of the automatic spiral fastening component 206 and the two actuator mounting frames 203. Figure 5 It shows the internal working mechanism by removing some structures, making the operation of the drive and torque adjustment components more intuitive. Figure 6 It presents the overall structure from another angle, further revealing the interaction between components. And Figure 7 It focuses on the power and torque adjustment part, highlighting its core function.

[0075] The specific structural details are as follows, including:

[0076] 1) Connector 204: Designed as a long box structure, with convex parts extending outward on both the upper and lower sides of the middle section in the long direction. In this section to the convex area, a chute 01 is designed, which provides an accurate path for the movement and locking of other components.

[0077] 2) Drive pulley assembly 02: It includes a pulley body 021 and a translation slide 022. The translation slide 022 can move or lock flexibly along the chute 01, ensuring the smooth engagement and separation between the pulley body 021 and the transmission belt. This design not only improves work efficiency but also enhances the stability of the system.

[0078] 3) Torque adjustment cylinder 03: Its main body is firmly installed on the connector 204 and is responsible for moving or locking the drive pulley assembly 02. By precisely controlling the action of the cylinder, precise adjustment of the fastening torque can be achieved.

[0079] 4) Transmission motor 04: Its main body is fixed on the translation slide 022, and its output shaft is in transmission connection with the axle of the pulley body 021. This design enables the rotational power of the motor to be efficiently and stably transmitted to the pulley assembly, thus ensuring the smooth progress of the fastening operation.

[0080] 5) Driven pulley assembly 06: It includes two pulleys 061. Each pulley is restricted or allowed to move a certain small distance axially and can rotate freely radially. These pulleys have screw holes that fit the center of the gas meter interface thread and correspond to the docking joint 205. The two pulleys are connected by a transmission belt 062 to jointly achieve power transmission and fastening operations. To ensure the precise positioning of the pulley 061, an annular groove 063 is provided on its bottom surface, and a part that matches the annular groove 063 is provided on the upper surface of the bottom plate of the actuator mounting frame 203, thereby realizing the position fixation of the pulley.

[0081] The power transmission process of the automatic spiral fastening assembly 206 involves delicate torque control and mechanical fit to ensure the accurate engagement of the gas meter interface with the corresponding components. The following is the improved description of the working process:

[0082] S1 Initial positioning and connection: First, through an external transmission mechanism (such as a robotic arm, etc.), the gas meter is precisely transferred to a position where its interface is aligned with the automatic spiral fastening assembly 206 to achieve preliminary docking.

[0083] S2 Pulley engagement: Next, the torque adjustment cylinder 03 is activated, pushing the slide 022 of the drive pulley assembly 02 along the chute 01 of the connector 204. This action causes the pulley body 021 to slightly engage with the transmission belt, preparing for the subsequent rotation action. The drive motor 04 starts to operate. At this time, the two pulleys 061 of the driven pulley assembly 06 are in a critical state with the transmission belt, that is, switching between slipping and effective transmission, to ensure that the torque transmitted to the gas meter interface remains minimal during the initial thread engagement stage to avoid damaging the threads.

[0084] S3 Torque adjustment: As the engagement progresses, the torque adjustment cylinder 03 continues to adjust, gradually increasing the wrap angle of the drive pulley assembly 02 in contact with the transmission belt, thereby gradually increasing the torque transmitted to the gas meter interface. The transmission system monitors the slipping condition of the transmission belt and uses this information to adjust the torque in real time. If the torque is too large and causes the transmission belt to slip, the system will immediately interrupt the continuous increase of the torque to protect the gas meter interface from damage.

[0085] S4 Fastening completed: When the gas meter interface is basically fastened with the thread, the system further increases the thrust of the torque adjustment cylinder 03, causing the wrap angle between the drive pulley assembly 02 and the transmission belt to increase again. In this way, the transmission system applies the required fastening torque to the gas meter interface through the transmission belt. Due to the characteristic that the transmission belt slips when overloaded, this design can ensure that the fastening degrees obtained by the two interfaces are consistent, avoiding poor sealing or interface damage caused by uneven fastening.

[0086] Overall, the automatic spiral fastening assembly 206 achieves highly automated, precise and safe fastening of the gas meter interface through precise control and mechanical design, improving production efficiency and product quality.

[0087] To improve the detection efficiency, a series of optimizations have been made in the structure of the interface module 211 and the design of the conveying device 3 in the present invention. Specifically, it includes:

[0088] 1. Interface module layout: The interface module 211 adopts a rectangular planar layout, preferably a square. This layout is shown in Figure 1 , which helps to achieve more compact space utilization and improve the working efficiency of the equipment per unit area.

[0089] 2. Design of the conveying device: The conveying device 3 mainly includes a power-driven turntable 31 and a gas meter clamping assembly 32 fixed on this turntable. The gas meter clamping assembly 32 can move in three directions of X, Y, and Z. Such a design increases the flexibility of the device and its ability to adapt to gas meters of different sizes.

[0090] 3. Fixing of the measuring component: The measuring component 22 is also fixed on the turntable 31. In this way, when the turntable 31 rotates, the measuring component 22 can be quickly moved to each gas meter in the interface module 211 for deformation measurement, improving the overall detection speed.

[0091] 4. Optimization of the working process: During operation, the gas meter clamping assembly 32 first clamps the gas meter and then quickly moves to the corresponding working position through the rotation of the turntable 31. Whether it is for tightening operation or detection, such a process ensures an efficient and smooth operation sequence, shortens the conversion time of the gas meter between various processes, and improves the overall efficiency of the production line.

[0092] Through these optimization measures, the present invention significantly improves the processing capacity of the automatic spiral tightening and detection system for gas meters, achieves a higher production throughput, and at the same time maintains the accuracy and reliability of the operation. These improvements make the device particularly suitable for large-scale and high-efficiency gas meter production and testing environments.
