Description

Technical Field

[0001] This application relates to the field of gas meter manufacturing equipment technology, and in particular to an automatic running-in device for gas meter movement components. Background Technology

[0002] Currently, after the gas meter body is assembled, it usually needs to undergo a run-in test to determine the normal operation and accuracy of the gas meter body. The run-in test allows the gas meter body to adapt to the pressure and flow of the gas pipeline before operation, in order to check whether the connection of the gas meter body is firm and whether there are any problems such as gas leakage. At the same time, the running-in test can adjust the operating parameters of the gas meter body to ensure that the gas meter body can accurately measure the amount of gas used during normal use.

[0003] There are two types of existing gas meter running-in equipment. One type is cylindrical in shape. The cylindrical gas meter running-in equipment requires multiple sets of ventilation mechanisms to extend out. After the ventilation mechanisms are connected to the gas meter body under test, the ventilation mechanisms perform ventilation tests inside the gas meter body. The other type is cabinet-shaped. The gas meter body is placed inside the cabinet-shaped gas meter running-in equipment, and then the gas meter body is positioned under the ventilation mechanism through a transmission device before the gas meter body is subjected to a ventilation test.

[0004] In order to test the gas flow of multiple gas meters at the same time, it is usually necessary to put multiple gas meters into the gas meter running-in device. However, the existing gas meter running-in devices have different positions for testing the gas meters, so the gas meters to be tested need to be put in and taken out from different positions when putting in or taking out the running-in device, which makes it inconvenient to store and retrieve the gas meters. Summary of the Invention

[0005] To improve the convenience of accessing the gas meter body, this application provides an automatic running-in device for the gas meter movement assembly.

[0006] This application provides an automatic running-in device for gas meter movement components, employing the following technical solution:

[0007] An automatic running-in device for a gas meter movement assembly includes a rotating column and a support frame located around the rotating column. The support frame includes a detection component for detecting the running-in effect of the gas meter body. The detection component includes a rotating ring for supporting the gas meter body, which is fixedly connected to the rotating column. The detection component also includes an abutment ring. The rotating ring is located below the abutment ring. One side of the abutment ring is a feed inlet / outlet, and the other side is a detection part. The abutment ring is inclined on the support frame, with the feed inlet / outlet at the highest point and the detection part at the lowest point. Several detection frames extend upward from the upper surface of the rotating ring, each corresponding to a gas meter body. Each detection frame is slidably connected to a vent pipe for introducing gas into the gas meter body. The upper end of the vent pipe has an abutment part for abutting the abutment ring. Each vent pipe is connected to an air pump pipe. The upper end of the gas meter body has an air inlet. When the detection frame is below the detection part, the corresponding abutment part abuts the detection part, and the vent pipe slides down into the air inlet.

[0008] By adopting the above technical solution, when installing or removing the gas meter body, a transmission device or robotic arm can be used to remove the gas meter body that has completed the running-in test from the inlet / outlet section. Then, the transmission device or robotic arm is used to connect the gas meter body to be tested to the rotating ring. The rotating column can then be rotated, thereby driving the rotating ring to rotate. The above actions are repeated. After the gas meter body to be tested rotates to the testing section, the abutting part abuts against the abutting ring, and the vent pipe slides into the interior of the air inlet section to vent air into the gas meter body for testing. This allows for the running-in test and loading / unloading of several gas meter bodies without stopping the machine, improving the convenience of storing and retrieving the gas meter body.

[0009] Optionally, the detection components are arranged in several groups from top to bottom along the height direction of the support frame. The structures of the detection components are the same, and support columns are provided between the abutting rings.

[0010] By adopting the above technical solution, setting up several sets of detection components can simultaneously perform run-in tests on more gas meter bodies, further improving the efficiency of run-in tests on gas meter bodies and also improving the convenience of accessing gas meter bodies.

[0011] Optionally, the abutment part is a sliding wheel, and the upper end of the vent pipe extends to the outside of the detection frame and is provided with a wheel seat, and the sliding wheel is rotatably connected to the wheel seat.

[0012] By adopting the above technical solution, when the rotating column drives the rotating ring to rotate, if the abutting part moves to the position of abutting the abutting ring, the sliding wheel will move away from the abutting ring, thereby driving the vent pipe to move. As the rotating ring rotates further, the vent pipe moves further downward. At this time, the sliding wheel rolls, thereby reducing the friction between the sliding wheel and the abutting ring, thus improving the convenience of running-in testing the gas meter body.

[0013] Optionally, a restoring elastic element for restoring the wheel seat is provided between the wheel seat and the testing frame.

[0014] By adopting the above technical solution, as the rotating ring rotates, the force of the sliding wheel against the abutting ring is canceled. At this time, the restoring elastic element drives the wheel seat to move closer to the abutting ring, thereby driving the vent pipe to slide away from the air inlet. The vent pipe is separated from the air inlet, and the running-in test is over. When the gas meter body moves to the inlet / outlet, the gas meter body after the running-in test can be taken out using a transmission device or a robotic arm.

[0015] Optionally, the outside of the inlet / outlet is provided with a feeding conveyor belt for transporting the gas meter body to be tested, and a feeding robot arm for gripping the gas meter body is provided on one side of the feeding conveyor belt.

[0016] By adopting the above technical solution, during the feeding process, a feeding robot can be used to install the gas meter body on the feeding conveyor belt onto the rotating ring, which is highly efficient in installing the gas meter body to be tested.

[0017] Optionally, the outside of the inlet / outlet is provided with a feeding conveyor belt for conveying the gas meter body after running-in, and a feeding robot arm for gripping the gas meter body is provided on one side of the feeding conveyor belt.

[0018] By adopting the above technical solution, during the unloading process, a unloading robot can be used to remove the gas meter body that has completed the running-in test from the rotating ring, and then place it on the upper end of the unloading conveyor belt to complete the unloading. The unloading of the gas meter body is highly convenient.

[0019] Optionally, the gas meter body is detachably connected to the rotating ring. The upper end face of the rotating ring is provided with several sliding seats. The upper end of the sliding seats is provided with a sliding groove. The lower end of the gas meter body is provided with an extension for connecting with the sliding seats. The extension is adapted to the sliding groove.

[0020] By adopting the above technical solution, when installing the gas meter body onto the rotating ring, the extension can be directly installed horizontally into the sliding seat using a loading robot, thus completing the installation of the gas meter body. The installation is relatively stable.

[0021] Optionally, the testing frame has a clearance hole on the side near the rotating column, and the width of the clearance hole is adapted to the diameter of the air pump pipe.

[0022] By adopting the above technical solution, as the air tube slides downward, the air pump tube moves within the clearance hole, thereby improving the stability of the air pump tube.

[0023] Optionally, a positioning block is slidably connected to the lower end of the vent pipe, and the gas meter body has a slot that matches the positioning block, with the air inlet connected to the slot.

[0024] By adopting the above technical solution, when the vent pipe slides into the interior of the air inlet, the positioning block falls into the interior of the slot. The slot can position the gas meter body, thereby improving the stability of the gas flow into the interior of the gas meter body.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. When installing or removing the gas meter body, a transmission device or robotic arm can be used to remove the gas meter body that has completed the running-in test from the inlet / outlet section. Then, the transmission device or robotic arm is used to connect the gas meter body to be tested to the rotating ring. The rotating column can then be rotated, which in turn drives the rotating ring to rotate. The above actions are repeated. After the gas meter body to be tested rotates to the testing section, the abutting part abuts against the abutting ring, and the vent pipe slides into the air inlet section to vent air into the gas meter body for testing. This allows for running-in tests and loading / unloading of several gas meter bodies without stopping the machine, which improves the convenience of storing and retrieving gas meter bodies.

[0027] 2. Setting up several sets of detection components can simultaneously perform running-in tests on more gas meter bodies, further improving the efficiency of running-in tests on gas meter bodies and also improving the convenience of accessing gas meter bodies.

[0028] 3. When the rotating column drives the rotating ring to rotate, if the abutting part moves to the position of abutting the abutting ring, the sliding wheel will move away from the abutting ring, thereby driving the vent pipe to move. As the rotating ring rotates further, the vent pipe moves further downward. At this time, the sliding wheel rolls, thereby reducing the friction between the sliding wheel and the abutting ring, thus improving the convenience of running-in testing the gas meter body.

Detailed Implementation

[0034] The present application will be further described in detail below with reference to all the accompanying drawings.

[0035] This application discloses an automatic running-in device for gas meter movement components.

[0036] Reference Figure 1 and Figure 2 An automatic running-in device for gas meter movement components includes a rotating column 1 and a support frame 2 located around the rotating column 1. The support frame 2 includes a detection component for detecting the running-in effect of the gas meter body 100.

[0037] Reference Figure 2 and Figure 3The detection assembly includes a rotating ring 21 for supporting the gas meter body 100, which is detachably connected to the rotating ring 21. Several detection frames 211 extend upwards from the upper surface of the rotating ring 21, each corresponding to a gas meter body 100. The detection assembly also includes an abutting ring 22 located above the rotating ring 21. The detection frames 211 are located between the rotating ring 21 and the abutting ring 22. The abutting ring 22 is inclinedly mounted on a support frame 2. One side of the abutting ring 22 is designated as an inlet / outlet 221, and the other side is designated as a detection part 222. The inlet / outlet 221 is located at... At the highest point, the detection unit 222 is located at the lowest point. A vent pipe 212 for introducing detection gas into the gas meter body 100 is slidably connected to the detection frame 211. When the detection frame 211 rotates to the detection unit 222, the detection frame 211 can vent gas into the gas meter body 100 to perform a running-in test on the gas meter body 100. When the detection frame 211 moves to below the detection unit 222, the corresponding abutting part abuts against the detection unit 222, and the vent pipe 212 slides down into the gas meter body 100 to vent gas into the gas meter body 100. Then, the running-in test of the gas meter body 100 can begin.

[0038] Reference Figure 2 and Figure 3 The outer side of the inlet / outlet 221 is provided with a feeding conveyor belt 31 for transporting the gas meter body 100 to be tested. Several gas meter bodies 100 are arranged at equal intervals on the feeding conveyor belt 31. A feeding robot 3 is provided on one side of the feeding conveyor belt 31 for gripping the gas meter body 100. During feeding, the feeding robot 3 grips the gas meter body 100 to be tested and then moves the gas meter body 100 to the upper end of the rotating ring 21.

[0039] Reference Figure 2 and Figure 3 The upper end of the rotating ring 21 is provided with several sliding seats 217 at equal intervals. The upper end of the sliding seat 217 is provided with a sliding groove 218. The lower end of the gas meter body 100 is provided with an extension 102 for connecting with the sliding seat 217. The extension 102 is adapted to the sliding groove 218. As the feeding robot 3 is driven, the extension 102 is slid into the interior of the sliding groove 218, and the gas meter body 100 and the sliding seat 217 are engaged, which makes feeding more convenient.

[0040] Reference Figure 2 and Figure 3A base is provided below the rotating column 1, and a drive motor is vertically installed inside the base. The output shaft of the drive motor is fixedly connected to the rotating column 1. The user then operates the output shaft of the drive motor to rotate, which in turn drives the rotating column 1 to rotate, which in turn drives the rotating ring 21 to rotate. As the rotating ring 21 rotates, the next sliding seat 217 is placed in the position facing the loading robot 3. Then the loading robot 3 can be operated to repeat the above actions to load materials.

[0041] The detection components can be arranged in multiple ways from top to bottom along the height direction of the support frame 2. The structures of the detection components can be the same. Support columns 223 are arranged between the abutting rings 22. The support columns 223 pass through the lowest abutting ring 22 and abut against the ground. Setting up multiple sets of detection components can simultaneously perform running-in tests on more gas meter bodies 100, further improving the efficiency of running-in tests on gas meter bodies 100 and also improving the convenience of storing and retrieving gas meter bodies 100.

[0042] Reference Figure 2 and Figure 3 The upper end of the rotating ring 21 extends upward with a plurality of detection frames 211, each of which corresponds to a sliding seat 217. Each detection frame 211 is slidably connected to a vent pipe 212 for introducing gas into the gas meter body 100. The upper end of the vent pipe 212 is provided with an abutment part for abutting against the abutment ring 22. As the rotating ring 21 rotates continuously, it drives the detection frames 211 to move. When the detection frame 211 moves to a position close to the detection part 222, the abutment part abuts against the detection part 222 of the abutment ring 22.

[0043] Reference Figure 2 and Figure 3 The abutting part can be a sliding wheel 214. The upper end of the vent pipe 212 extends to the outside of the detection frame 211 and is provided with a wheel seat 215. The sliding wheel 214 is rotatably connected to the wheel seat 215. As the rotating ring 21 continues to rotate, the sliding wheel 214 rubs against the surface of the abutting ring 22, and the sliding wheel 214 rolls, thereby reducing the friction between the sliding wheel 214 and the abutting ring 22, thereby improving the convenience of running-in testing the gas meter body 100.

[0044] Reference Figure 3 and Figure 4The vent pipe 212 gradually moves towards the gas meter body 100. Each vent pipe 212 is connected to an air pump pipe 213, which is located below the vent pipe 212. An air inlet 101 is located at the upper end of the gas meter body 100. A positioning block 5 is slidably connected to the lower end of the vent pipe 212. The gas meter body 100 has a slot 103 that matches the positioning block 5. The air inlet 101 communicates with the slot 103. As the vent pipe 212 continues to slide downwards, it inserts into the air inlet 101. When the vent pipe 212 slides into the air inlet 101, the positioning block 5 falls into the slot 103. The detection frame 211 has a clearance hole 23 that matches the diameter of the air pump pipe 213. The clearance hole 23 is located near the rotating column 1 of the detection frame 211 (see reference). Figure 1 On one side, as the vent pipe 212 slides downward, the air pump pipe 213 moves within the clearance hole 23, thereby improving the stability of the air pump pipe 213. The slot 103 can position the gas meter body 100, thereby improving the stability of the gas flow into the gas meter body 100.

[0045] As air is pumped into the gas meter body 100 via the air pumping pipe 213, several gas meter bodies 100 located in the detection section 222 begin a break-in test.

[0046] Reference Figure 2 and Figure 3 As the rotating ring 21 continues to rotate, the gas meter body 100 gradually moves towards the inlet / outlet 221. A restoring elastic element 216 for restoring the wheel seat 215 is provided between the wheel seat 215 and the test frame 211. The pressure of the abutting ring 22 on the sliding wheel 214 gradually decreases. The restoring elastic element 216 drives the wheel seat 215 and the sliding wheel 214 to return to the direction of the abutting ring 22. As the rotating ring 21 continues to rotate, the sliding wheel 214 separates from the abutting ring 22, and the vent pipe 212 moves out to the outside of the air inlet 101. At this time, no more air is vented into the gas meter body 100, and the running-in test ends.

[0047] The restoring elastic element 216 can be a restoring spring, which can restore the elastic deformation after it has occurred.

[0048] Reference Figure 2 and Figure 3The outside of the inlet / outlet section 221 is provided with a feeding conveyor belt 41 for conveying the gas meter body 100 after running-in. One end of the feeding conveyor belt 41 is provided with a feeding robot 4 for clamping the gas meter body 100. As the rotating ring 21 continues to rotate, the gas meter body 100 rotates to the position of the inlet / outlet section 221. The user can then operate the feeding robot 4 to clamp the gas meter body 100 that has completed the running-in test on the rotating ring 21, and then pull the gas meter body 100 away from the rotating ring 21 to slide the extension out of the sliding groove 218, thereby removing the gas meter body 100 from the rotating ring 21 and placing it on the upper end of the feeding conveyor belt 41 to complete the feeding. The disassembly of the gas meter body 100 is highly convenient.

[0049] During the running-in test of the gas meter body 100, the gas meter body 100 can be loaded, tested, conveyed, and unloaded without stopping the machine.

[0050] The loading robot 3 and the unloading robot 4 are both existing technologies, and will not be described in detail in this embodiment.

[0051] The implementation principle of the automatic running-in device for the gas meter core assembly in this application embodiment is as follows: During material loading, the gas meter body 100 to be tested for running-in is installed onto the rotating ring 21 using the loading robot 3. Then, the rotation of the drive motor is operated to drive the rotating column 1 to rotate, which in turn drives the rotating ring 21 to rotate, which in turn drives the gas meter body 100 located on the upper end face of the rotating ring 21 to rotate. When the gas meter body 100 moves to a position close to the detection part 222, the sliding wheel 214 abuts against the abutting ring 22, and then the sliding wheel 214 rolls. The vent pipe 212 moves towards the gas meter body 100 and is inserted into the interior of the air inlet 101. At this time, the air pump pipe 213 pumps air into the air inlet. When the gas section 101 is ventilated, the gas will directly enter the interior of the gas meter body 100, at which time the gas meter body 100 begins to run-in test; as the rotating ring 21 continues to move, the restoring elastic element 216 drives the wheel seat 215 to return to the direction close to the abutting ring 22, and then the sliding wheel 214 disengages from the abutting ring 22; as the gas meter body 100 moves to the inlet / outlet section 221 again, the unloading robot 4 removes the gas meter body 100 from the rotating ring 21 and places it at the unloading conveyor belt 41, completing the unloading of the gas meter body 100. The gas meter body 100 is easy to disassemble and assemble, and can realize the loading, running-in test, conveying and unloading of the gas meter body 100 without stopping the machine.

[0052] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
