[0039] Furthermore, a handle 5 is also included. Example
[0040] See also Figure 1 An embodiment of the pipeline watertight and airtight flexible tooling of the present invention is composed of a cylinder tightening assembly 2, a cylinder fixing frame 3, a pipe support frame 4 and a handle 5 on a base plate 1. A plurality of positioning holes are arranged on the base plate 1. The cylinder tightening assembly 2, the cylinder fixing frame 3 and the pipe support frame 4 are all fixed on the base plate 1 through the positioning holes, and different positioning holes can be selected to adjust the positions of the cylinder tightening assembly 2, the cylinder fixing frame 3 and the pipe support frame 4 relative to the base plate to adapt to the shape of the pipe to be tested. A cylinder tightening assembly 2 is arranged at each opening of the pipe to be tested to seal the opening of the pipe to be tested. When the multiple openings of the pipe to be tested are not on the same plane, the cylinder tightening assembly 2 is arranged on a plane perpendicular to the base plate by using the cylinder fixing frame 3, and then the opening of the pipe to be tested is aligned by adjusting the angle of the cylinder tightening assembly 2 on this vertical plane. For the irregularly shaped or long pipe to be tested, the pipe support frame 4 is used to provide additional support for the pipe to be tested to ensure smooth sealing test. Handles 5 are arranged on both sides of the bottom plate 1 to facilitate carrying the assembled pipeline to be tested.
[0041] See also Figure 2The cylinder tightening assembly of one embodiment of the pipeline watertight and airtight flexible tooling of the present invention is composed of an adjustable bottom plate 201, a pipeline fixing assembly and a plug assembly. The adjustable bottom plate 201 is slotted and directly connected to the bottom plate or the cylinder fixing frame by bolts, or connected to the bottom plate or the cylinder fixing frame by a clamping block 202. The pipeline fixing assembly and the plug assembly are respectively located on both sides of the adjustable bottom plate 201 and arranged opposite to each other.
[0042] When the clamping block 202 is used for connection, one side of the clamping block 202 is connected to the bottom plate or the cylinder fixing frame by bolts, and the other side is attached to the adjustable bottom plate 201; when the bolts are tightened, the clamping block 202 presses the adjustable bottom plate 201 toward and fixes it to the bottom plate or the cylinder fixing frame, thereby fixing the cylinder top tightening assembly to the bottom plate or the cylinder fixing frame. The clamping block 202 can conveniently adjust the relative position and angle of the cylinder top tightening assembly without being restricted by the position of the positioning hole on the bottom plate.
[0043] The pipe fixing assembly includes a vertical slot 203, a fixing sheet 204, and an auxiliary slot 205. The vertical slot 203 is rigidly connected to the adjustable bottom plate 201, and the auxiliary slot 205 is arranged parallel to one side of the vertical slot 203. At the upper end of the vertical slot 203, there is a set of fixing sheets 204 that cooperate with the pipe to be tested and are used to clamp and fix the pipe to be tested. When the pipe to be tested is placed in the gaps of the vertical slot 203 and the auxiliary slot 205, the fixing sheet 204 closes the gap and fixes the pipe to be tested.
[0044] The plug assembly includes a fixing sleeve 206, a rubber plug 207, a cylinder rod 208, a cylinder fixing seat 209 and a cylinder 210. One end of the cylinder rod 208 is bolted to the rubber plug 207, and the other end is bolted to the cylinder 210. The rubber plug 207 is matched with the pipeline to be tested. When the cylinder 210 is actuated, the rubber plug 207 is driven by the cylinder rod 208 to move along the movement direction of the cylinder 210, and the rubber plug 207 is pressed into the opening of the pipeline to be tested, deformed, and blocks the outlet. After the test is completed, the cylinder moves in the opposite direction, and the rubber plug 207 leaves the pipeline to be tested. The cylinder 201 is fixed to the adjustable base plate 201 by bolts through the cylinder fixing seat 209.
[0045] The inner diameter of the fixing sleeve 206 is slightly larger than the rubber plug 207, and surrounds the outer side of the rubber plug 207. After the pipeline to be tested is fixed by the vertical slot 203, the auxiliary slot 205 and the fixing sheet 204, the fixing sleeve 206 connects the pipeline to be tested and the rubber plug 207 before the cylinder 210 is actuated, thus maintaining the stability of the pipeline to be tested and also serves as a guide for the rubber plug.
[0046] See also Figure 3The cylinder fixing frame 3 of an embodiment of the pipeline watertight and airtight flexible tooling of the present invention comprises a fixing frame bottom plate 301, a fixing frame vertical plate 302 and a side support plate 303. The fixing frame bottom plate 301 is provided with a hole, which can be fixed to the positioning hole of the bottom plate by bolts. The fixing frame vertical plate 302 is arranged with a positioning groove for connecting with the cylinder top tightening assembly. The fixing frame vertical plate 302 and the fixing frame bottom plate 301 are in a right-angle relationship and are fixed to one side of the fixing frame bottom plate 301, which can be bolted or welded; in this embodiment, the fixing frame vertical plate 302 and the fixing frame bottom plate 301 are connected by two left and right side support plates 303. The side support plate 303 is a right-angled triangle, one right-angled side is connected to the fixing frame bottom plate 301, and the other right-angled side is connected to the fixing frame bottom fixing frame vertical plate 302, forming a triangular fixation.
[0047] See also Figure 4 The pipeline support frame of an embodiment of the pipeline watertight and airtight flexible tooling of the present invention comprises a fixed seat 401, a sliding bracket 402 and a slider 403. The bottom of the fixed seat 401 has a through hole, which can be matched with the positioning hole on the bottom plate and fixed to the bottom plate by bolts. The sliding bracket 402 and the slider 403 constitute a support block for fixing the pipeline to be tested. The sliding bracket 402 has a guide groove, and one end of the slider 403 is embedded in the guide groove and can move along the direction of the guide groove to match the height of the pipeline to be tested. The other end of the slider 403 is used to connect with the pipeline to be tested to support the pipeline to be tested.
[0048] See also Figure 5 and Figure 6 When testing the pipeline to be tested using an embodiment of the pipeline watertight and airtight flexible tooling of the present invention, the position of the cylinder top tightening assembly is arranged using the cylinder fixing frame and the bottom plate according to the shape and opening position of the pipeline to be tested, and the outlet of the pipeline to be tested is aligned, and the pipeline support frame is set according to the actual situation to stably fix the pipeline to be tested. After the pipeline to be tested is assembled, the gas is connected to the cylinder, the cylinder is started, and all the openings of the pipeline to be tested are blocked, and the tooling belonging to this pipeline to be tested is completed. Then use the handle to put the assembled pipeline to be tested into the water, and confirm the sealing by observing whether there are bubbles in the water.
[0049] The joint between the cylinder tightening assembly and the pipe to be tested is made of rubber, and the pipe interface to be tested is generally made of metal. After the cylinder is tightened, the rubber deforms and seals, which is suitable for all joints.
[0050] After the test is completed, if you want to adapt to other pipelines to be tested, you can disassemble the cylinder tightening assembly, cylinder fixing frame, and pipeline support frame, adjust them freely, and then fix them according to the shape of the new pipeline to be tested to perform a new test.
[0051] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention. That is, any equivalent changes and modifications made according to the content of the patent application scope of the present invention should be within the technical scope of the present invention.
