Description

Technical Field

[0001] The present application relates to the technical field of rail transit vehicle manufacturing, and in particular to a tooling device for detecting leaks in different pipelines of a vehicle. Background Art

[0002] High-speed EMUs utilize a large number of various piping systems, including various metal air ducts, refrigeration piping for air conditioners and refrigerators, and PVB plastic piping for water supply and sanitation. Due to the high speeds of these trains, component reliability is highly demanding. Poor sealing in some piping can negatively impact train operation. For example, air duct leaks can cause a drop in air pressure, leading to minor noise and even severe vehicle shutdowns. Furthermore, poor sealing in other piping systems, such as refrigeration piping for air conditioners, refrigerators, and other refrigeration equipment, and water supply piping, can negatively impact the passenger experience.

[0003] When installing new vehicles or updating pipelines to deal with faults, it is necessary to conduct leak detection on pipelines of different models, thicknesses, and lengths used on the vehicle to prevent leakage of pipelines on the vehicle. However, in the prior art, there is no suitable tooling equipment to conveniently detect leaks in different pipelines. Often, only a simple visual inspection can be performed manually, and air, refrigerant, or nitrogen is filled in after assembly to detect leaks. However, if a leak is found after the pipeline is assembled at a later stage, the pipeline needs to be removed and replaced with a new one, which will cause the sealing gasket to be scrapped or increase the work of re-welding. At the same time, manual replacement of pipeline inspection after filling with nitrogen also has certain safety hazards, and it is inconvenient to mark the leak point.

[0004] Therefore, in order to solve the above problems, it is very necessary to develop a tooling equipment that is convenient for leak detection and identification of different pipelines in the production process of high-speed trains.

The sliding displacement of the sealing component 3 is used to adjust the relative distance between the sealing component 3 and the adjusting component 4, so that pipelines to be detected with different axial lengths can be clamped between the sealing component 3 and the adjusting component 4; the rotating component 2 is installed on the base component 1, and is used to drive the pipeline to be detected to roll and rotate. The adjusting component 4 is used to adjust the height of the pipeline to be detected up and down, so that the clamped pipeline to be detected can contact the rotating component 2, so as to achieve the effect that pipelines to be detected with different radial sizes are driven to rotate by the rotating component 2 respectively, thereby achieving the effect that the tooling equipment is adapted to pipelines with different axial lengths and different radial sizes for leak detection.

[0037] like Figures 1 to 3 As shown, in the embodiment of the present application, the adjustment component 4 includes an adjustment plate 401; the adjustment plate 401 is vertically extended and installed on one side above the base 101 of the base component 1; the adjustment plate 401 is provided with an adjustment groove 402 extending vertically up and down, and the joint unit 404 can be slid up and down in the adjustment groove 402; a positioning unit is provided between the joint unit 404 and the adjustment plate 401, which is used to position and fix the joint unit 404 that slides up and down, so that the joint unit 404 after the height is adjusted up and down can be positioned and fixed, so as to move the clamped pipeline to be tested up and down, so as to adapt to leak detection of pipelines to be tested with different radial sizes.

[0038] In the embodiment of the present application, the positioning unit includes a positioning piece 405; the positioning piece 405 extends horizontally, and a positioning sleeve is provided in the middle of the positioning piece 405, and the positioning sleeve is arranged on the outer periphery of the joint unit 404; a positioning screw is provided on the positioning piece 405 and a positioning slot 403 extending vertically up and down for the positioning screw to pass through is provided on the adjustment plate 401, and the positioning screw passes through the end of the positioning piece 405 and the adjustment plate 401 in turn and is tightened with a positioning nut 407, and the adjustment plate 401 and the positioning piece 405 are clamped and fixed by tightening the positioning screw and the positioning nut 407.

[0039] like Figures 1 to 3 As shown, in the embodiment of the present application, the connector unit 404 includes a first connector 408 and a second connector 409, which are coaxially arranged and connected via a connecting portion; the connecting portion is in the adjusting groove 402 on the adjusting plate 401; the first connector 408 and the second connector 409 are located on opposite sides of the adjusting plate 401, and the first connector 408 is arranged toward the blocking component 3 for relative insertion of the first end of the pipeline to be detected. Optionally, the first connector 408 can be detachably installed on the connecting portion so that a plurality of first connectors 408 of different matching models can be installed at the connecting portion respectively and correspondingly, so that the first ends of pipelines to be detected of different models are correspondingly inserted into the first connectors 408 of the corresponding models, thereby achieving the effect of adaptive plug-in installation of the pipeline to be detected. Of course, in order to improve the sealing performance of the pipeline to be detected, a sealing bearing can also be installed at the first connector 408 so that the pipeline to be detected can be relatively rotatably plugged and installed at the first connector 408 via the sealing bearing.

[0040] At the same time, the second connector 409 is used to allow external soapy water to flow in, so that the soapy water flows into the blocked pipeline to be tested through the connector unit 404, and the leaking point is directly identified by the soapy water leaking through the outer wall of the pipeline.

[0041] In the embodiment of the present application, the leak point tooling is optionally further equipped with a soap bubble liquid injection component to provide soap bubble liquid to the interior of the pipeline to be tested. The detection of soap bubble liquid flowing out from the pipe wall makes it easier to identify the pipeline leak. At the same time, the soap bubble liquid injection component includes a water storage chamber for storing soap bubble liquid; the outlet of the water storage chamber is connected to the inlet of a water pump, the outlet of the water pump is connected to the inlet of the water injection pipe, and the outlet of the water injection pipe is connected to the second connector 409 of the interface unit of the regulating component 4 for relative plug connection, so as to inject soap bubble liquid into the pipeline to be tested, so as to facilitate the identification of the leak point by using the soap bubble liquid leaking from the leak point on the pipeline to be tested. (Not indicated in the drawings)

[0042] like Figures 1 to 4 As shown, in the embodiment of the present application, the blocking assembly 3 includes a slider 301, a sliding drive motor 302 and a screw transmission structure; the slider 301 can be relatively slidably installed in the slide groove 104 on the base assembly 1, and the slide groove 104 extends horizontally, and the extension direction is perpendicular to the adjustment plate 401 of the adjustment assembly 4; a blocking plate 309 extending vertically upward is installed on the slider 301, and the blocking plate 309 is arranged opposite to the adjustment plate 401, and is used to block the second end of the pipeline to be tested; the sliding drive motor 302 is fixedly installed on the base assembly 1, and the output end of the sliding drive motor 302 is connected to the slider 301 via the screw transmission structure, and is used to drive the slider 301 to slide relatively along the slide groove 104.

[0043] In the embodiment of the present application, the screw transmission structure includes a driving screw 303, which extends in a parallel direction along the slide groove 104, one end of the driving screw 303 is connected to the output end of the sliding drive motor 302, and the other end is rotatably connected to the base 101 of the base assembly 1; the slider 301 is provided with a wire sleeve 305 for the driving screw 303 to pass through and engage with the screw; a sliding structure is also provided between the slider 301 and the base assembly 1, which is used to limit the position between the slider 301 and the base assembly 1 so that only relative sliding displacement can be generated.

[0045] At the same time, in order to prevent the slider 301 from sliding too fast due to the drive of the lead screw, resulting in excessive clamping impact force on the pipeline to be inspected, a buffer spring 308 can be mounted on the slide rod 304. The buffer spring 308 is located at one end of the slide rod 304 close to the base assembly 1. One end of the buffer spring 308 is fixedly connected to the base 101 of the base assembly 1, and the other end is freely set. The free end of the buffer spring 308 is connected to the vertically set buffer plate 307 mounted on the slide rod 304, so that the slider 301 contacts the buffer plate 307 during the inward sliding process, thereby slowing down the movement rate of the slider 301 when sliding inward, preventing the slider 301 from colliding with the second end of the pipeline to be inspected and causing damage to the pipeline.

A transmission shaft 202 is provided at one end of the first roller body 2041 and is connected to a driven wheel after passing through the mounting plate on the same side. The driven wheel is threadedly engaged with the driving gear 206, so that the first roller body 2041 forms an active roller and the second roller body 2042 forms a passive roller. The two roller bodies 204 located on the left and right sides of the pipeline to be detected are used to drive them to rotate around the axis to identify and mark leakage points in different radial directions on the pipeline to be detected.

[0049] In the embodiment of the present application, the specific working method of the pipeline leak detection tool is as follows:

[0050] Step S1. Placement of pipeline to be inspected:

Based on the diameter of the pipeline to be tested, tighten the positioning bolt 406 on the adjustment plate 401 of the adjustment assembly 4 and adjust the relative position of the joint unit 404 on the adjustment slot 402. Replace the first joint 408 with a sealed bearing that matches the diameter of the pipeline to be tested. The first end of the pipeline to be tested is fixedly connected to the first joint 408.

[0054] Step S22: The sliding drive motor 302 in the blocking assembly 3 drives the drive screw 303 to rotate, and the rotation of the drive screw 303 drives the slider 301 to move in the chute 104 toward the adjustment assembly 4 until the second end of the pipeline to be inspected is blocked by the blocking plate 309;
