Description

Technical Field

[0001] The present application relates to the technical field of air tightness detection devices, and in particular to an online air tightness detection device applied to an auxiliary device of a gas meter. Background Art

[0002] A gas meter is an instrument installed on a gas channel for counting. A gas meter is usually composed of a series of numbers and symbols, including decimal points, tonnage, cubic meters, etc. Among them, the most critical number is cubic meter, which represents the amount of gas used. Before the gas meter is sold, an air tightness detection device is required to perform an air tightness detection operation on it.

[0003] like Figure 1 As shown, the gas meter 7 is provided with a detection hole 71 and two mounting tubes 72. When the gas meters are tested in batches, the operator places the gas meters on the air tightness testing device in turn and presses the start button to test the gas meters. After the gas meters are tested, the gas meters are removed from the testing device. The operation steps are relatively cumbersome, which affects the overall efficiency of the gas meter testing and needs to be improved. Utility Model Content

[0004] The purpose of this application is to provide an online sealing detection device for use in a gas meter accessory device in order to improve the overall detection efficiency of the gas meter.

[0005] The present application provides an online sealing detection device for a gas meter accessory device, which adopts the following technical solution: it includes a detection platform, which is slidably connected to several mounting plates for installing the gas meter, the detection platform is connected to a lifting assembly for driving the mounting plate to rise and fall, the detection platform is connected to at least two stopping mechanisms for limiting the movement of the mounting plate, the lifting assembly is located between two of the stopping mechanisms, the detection platform is connected to a detection mechanism corresponding to the lifting assembly, and the detection platform is connected to a transport assembly for driving the mounting plate to slide toward the detection mechanism.

[0006] By adopting the above technical solution, the gas meter is placed on the mounting plate, and the transport assembly drives the mounting plate to slide in the direction close to the detection mechanism. One of the stop mechanisms limits the sliding of the mounting plate, so that the mounting plate corresponds to the lifting assembly. The lifting assembly drives the mounting plate to rise, and the detection mechanism detects the gas meter on the mounting plate. Other stop mechanisms limit the sliding of other mounting plates to prevent other mounting plates from affecting the lifting of the mounting plate corresponding to the lifting assembly. When the gas meter is inspected, the lifting assembly drives the mounting plate to descend, and one of the stop mechanisms no longer limits the movement of the mounting plate, so that the gas meter after inspection moves to the next working state. This application uses automated detection of gas meters, reducing manual operations and improving the overall efficiency of gas meter inspection.

[0007] Optionally, the mounting plate is provided with a limiting block, and the limiting block is provided with a first limiting groove for cooperating with the gas meter and a second limiting groove for cooperating with the mounting pipe of the gas meter.

[0008] By adopting the above technical solution, when the gas meter is placed on the mounting plate, the outer surface of the gas meter abuts against the inner wall of the first limiting groove, and the two mounting tubes of the gas meter abut against the inner wall of the second limiting groove. The inner walls of the first limiting groove and the second limiting groove restrict the horizontal movement of the gas meter, thereby improving the stability of the gas meter on the mounting plate. The first limiting groove and the second limiting groove play a role in positioning the gas meter, ensuring that the gas meter is accurately installed on the mounting plate.

[0009] Optionally, the detection mechanism includes a sealing plate slidably connected to the detection platform, a carrier plate slidably connected to the detection platform, a detection tube connected to the carrier plate, a detector connected to the detection tube, a first driving member for driving the sealing plate to slide toward or away from the mounting plate, and a second driving member for driving the carrier plate to slide toward or away from the mounting plate, the detection tube is used to cooperate with the detection hole of the gas meter, the first driving member and the second driving member are connected to the detection platform, and the sealing plate is provided with a sealing column for cooperating with the mounting tube of the gas meter.

[0010] By adopting this technical solution, after the mounting plate is lifted by the lifting assembly, the first driving member drives the blocking plate to slide toward the mounting plate, clamping the gas meter between the inner wall of the first limiting groove and the blocking plate, thereby improving the stability of the gas meter's installation on the mounting plate. The blocking column snaps into the corresponding mounting tube, sealing the gas meter. The second driving member drives the carrier plate to slide toward the mounting plate, allowing the detection tube to snap into the detection hole, allowing the detector to test the gas meter.

[0011] Optionally, the detection platform is slidably connected to a clamping plate, the mounting plate is located between the clamping plate and the blocking plate, and the detection platform is connected to a third driving member for driving the clamping plate to slide toward or away from the blocking plate.

[0012] By adopting the above technical solution, after the mounting plate is lifted by the lifting assembly, the third driving member drives the clamping plate to slide toward the mounting plate, so that the detector is clamped by the clamping plate and the sealing plate, thereby improving the stability of the gas meter installed on the mounting plate.

[0013] Optionally, the lifting assembly includes a lifting plate slidably connected to the detection platform and a fourth driving member for driving the lifting plate to slide toward or away from the mounting plate, and the fourth driving member is connected to the detection platform.

[0014] By adopting the above technical solution, when the mounting plate corresponds to the lifting plate, the fourth driving member drives the lifting plate to slide toward the mounting plate, the lifting plate abuts against the mounting plate and causes the mounting plate to separate from the transport component, preventing the transport component from affecting the detector's detection of the gas meter.

[0015] Optionally, the lifting plate is provided with at least two positioning columns, and the mounting plate is provided with positioning holes for cooperating with the positioning columns.

[0016] By adopting the above technical solution, the positioning column is inserted into the positioning hole, and the outer surface of the positioning column fits with the inner wall of the positioning hole. The positioning column limits the horizontal movement of the mounting plate, thereby improving the stability of the mounting plate installed on the lifting plate.

[0017] Optionally, the radius of the positioning column increases step by step in a direction approaching the lifting plate.

[0018] By adopting the above technical solution, the positioning column can be easily inserted into the positioning hole, thereby improving the accuracy of placing the mounting plate on the lifting plate.

[0019] Optionally, the stopping mechanism includes a connecting column connected to the detection platform, a stopping plate rotatably connected to the connecting column, and a driving assembly for driving the stopping plate to rotate toward the direction approaching the mounting plate.

[0020] By adopting the above technical solution, the driving assembly drives the stop plate to rotate in a direction close to the mounting plate, so that the stop plate can abut against the mounting plate, thereby limiting the movement of the mounting plate.

[0021] Optionally, the driving assembly includes an active rod slidably connected to the detection platform and a fifth driving member for driving the active rod to slide toward or away from the stop plate, and the fifth driving member is connected to the detection platform.

[0022] By adopting the above technical solution, the fifth driving member drives the active rod to slide toward the direction close to the stop plate, the active rod abuts against the stop plate and drives the stop plate to rotate around the axis of the connecting column, so that the stop rod can limit the movement of the mounting plate; the fifth driving member drives the active rod to slide toward the direction away from the stop plate, the active rod separates from the stop plate, and the stop plate rotates toward the direction away from the mounting plate under the influence of gravity, so that the transport assembly continues to drive the mounting plate to move.

[0023] Optionally, the stop plate is connected to the testing platform via a reset member.

[0024] By adopting the above technical solution, the reset member drives the stop plate to reset so as to proceed with the next work, thereby improving work efficiency.

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

[0026] 1. After the gas meter is inspected, the lifting assembly drives the mounting plate down, and one of the stop mechanisms no longer restricts the movement of the mounting plate, allowing the inspected gas meter to move to the next working state. Automated gas meter inspection reduces manual labor and improves overall gas meter inspection efficiency.

[0027] 2. The positioning column is inserted into the positioning hole, and the outer surface of the positioning column fits with the inner wall of the positioning hole. The positioning column limits the horizontal movement of the mounting plate, thereby improving the stability of the mounting plate installed on the lifting plate. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Combine Figure 6 、 Figure 7 、 Figure 8 and Figure 9As shown, the inspection platform 1 is fixedly connected to a support plate 14 corresponding to the carrier plate 42. The support plate 14 is connected to a lifting assembly 5 for driving the mounting plate 2 to rise and fall.

At least two positioning posts 511 are provided on the side of the lifting plate 51 away from the fourth driving member 52 (the number of positioning posts 511 is selected based on actual needs). In this embodiment, there are two positioning posts 511. The positioning posts 511 are integrally formed with the lifting plate 51.

[0045] The implementation principle of the online sealing detection device applied to the gas meter attachment device in the embodiment of the present application is as follows:

[0046] After the gas meter 7 is assembled, it moves along with the mounting plate 2 onto the drive chain 32. The drive chain 32 drives the mounting plate 2 to slide toward the lifting plate 51. The stop plate 62 farthest from the mounting plate 2 rotates, limiting the sliding movement of the mounting plate 2. This mounting plate 2 corresponds to the lifting plate 51. When the mounting plate 2 is located between two stop plates 62, the other stop plate 62 rotates, limiting the movement of the remaining mounting plate 2. The controller controls the opening of the fourth drive member 52, which drives the lifting plate 51 to slide toward the mounting plate 2. The lifting plate 51 contacts the mounting plate 2 and lifts the mounting plate 2, causing the gas meter 7 to align with the clamping plate 12 and the sealing plate 41. The controller controls the second drive member 45 and the third drive member 13 to open, so that the gas meter 7 is clamped by the clamping plate 12 and the sealing plate 41, and the sealing column 411 is engaged with the mounting tube 72. The controller controls the first drive member 44 to open, and the first drive member 44 drives the carrier plate 42 to move toward the gas meter 7, so that the detection tube 43 is engaged with the detection hole 71. The detector inflates the gas meter 7 through the detection tube 43, thereby testing the sealing of the gas meter 7. After the gas meter 7 is tested, the clamping plate 12 and the sealing plate 41 release the gas meter 7. The fourth drive member 52 drives the lifting plate 51 to slide away from the mounting plate 2, so that the mounting plate 2 falls back onto the transmission chain 32. The stop plate 62 closest to the rotating motor 34 rotates. This stop plate 62 no longer restricts the movement of the mounting plate 2, allowing the transmission chain 32 to drive the gas meter 7 to the next operating state after the test is completed.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
