Description

Technical Field

[0001] The present invention relates to the technical field of air tightness detection of grooved pipe fittings, and in particular to an air tightness detection device and method for grooved pipe fittings. Background Art

[0002] Grooved pipe fittings are widely used in fire protection, electric power, telecommunications, municipal construction, chemical industry, coal mining and other fields. They mainly include straight-through, tee-through, special-shaped pipes, clamps and other types. Pipes are connected by clamps or hoops, which is an improved connection method instead of traditional flanges and welding. In the production process of grooved pipe fittings, the through grooves need to be tested for air tightness, while most traditional testing devices can only test the air tightness of straight-through pipes, but not the air tightness of tees and crosses, resulting in low practicality.

[0003] The existing authorized patent with publication number CN219694472U discloses a novel groove pipe fitting air tightness detection device, including a base and a lifting mechanism. The novel groove pipe fitting air tightness detection device is provided with a fixed frame, and the top view design of the fixed frame is a square structure, and there are four cylinders and movable blocks distributed at equal angles about the center of the fixed frame. When the air tightness detection of the four-way pipe fitting is performed, the four cylinders are started at the same time, so that the four rubber pads on the four movable blocks can seal the four ends of the four-way pipe at the same time. When the air tightness detection of the three-way pipe fitting is performed, the three cylinders are started, so that the three rubber pads on the three movable blocks can seal the end of the three-way pipe at the same time. When the air tightness detection of the straight-through pipe fitting is performed, the two cylinders are started, so that the two rubber pads on the two movable blocks can seal the two ends of the straight-through pipe at the same time. Therefore, the groove pipe fitting air tightness detection device can perform air tightness detection on the straight-through pipe, the three-way pipe and the four-way pipe, thereby improving the practicality of the device.

[0004] However, when the above method is used and the above device inspects the grooved pipe fittings, the pipe fittings need to be manually placed in the corresponding inspection area first, and then after the inspection is completed, the operator manually takes out the grooved pipe fittings after the inspection and places the subsequent pipe fittings. In this way, when inspecting continuous pipe fittings, the time for disassembly of the pipe fittings after the inspection is completed and the time for installation of new pipe fittings to be tested overlap each other, that is, the operator needs to completely withdraw the pipe fittings after the inspection from the inspection platform before placing the subsequent pipe fittings for inspection, which results in a long time-consuming connection of multiple pipe fitting connection inspections. Once a large number of pipe fittings are inspected, the labor intensity of the operators will increase, and the overall inspection efficiency of a large number of pipe fittings will also be affected. Summary of the invention

[0005] The object of the present invention is to provide an air tightness detection device and method for grooved pipe fittings, which can automatically unload the workpiece after the detection is completed through the provided components, shorten the connection time during the detection of multiple pipe fittings, and improve the overall detection efficiency of large quantities of pipe fittings.

[0047] S1: The grooved pipe is placed and installed on the turning frame 107 by means of the limiting member provided on the turning frame 107, and then the turning frame 107 with the grooved pipe placed thereon is moved into the detection area of ​​the blocking member and the inflatable member by means of the rotation of the rotating frame 106 and the up and down movement of the lifting platform 105;

[0048] S2: Then, the sealing member cooperates with the inflatable member to perform air tightness test on the grooved pipe placed on the corresponding turning frame 107, and at this time, the turning frame 107 located in the loading area places and installs new grooved pipes on the corresponding limiting member;

[0049] S3: After the air tightness test of the grooved pipes on the corresponding turning frames 107 is completed, the three turning frames 107 on the rotating frame 106 are rotated in coordination with the lifting platform 105 to perform the next round of position change, so that the turning frame 107 with the tested grooved pipes is rotated to the top of the transmission platform 102, and the turning frame 107 that installed the grooved pipes in the previous grooved pipe testing process moves the installed grooved pipes into the testing area of ​​the blocking member and the inflatable member;

[0050] S4: When the grooved pipes located in the detection area are detected by the blocking member and the inflatable member, the turning frame 107 matched with the grooved pipes after the detection will allow the grooved pipes to fall onto the transmission platform 102 for unloading and transfer through the turning of the turning frame 107 and the limiting member. At this time, the turning frame 107 located in the loading area is loading, so that the loading, detection and unloading processes of the grooved pipes are cyclically carried out synchronously, realizing automatic unloading of the grooved pipes after detection, and also reducing the connection time consumed in the process of detecting multiple grooved pipes one by one.
