Description

Technical Field

[0001] This invention relates to the field of waterproof material testing technology, specifically a waterproof roll testing frame. Background Technology

[0002] Waterproof membranes are widely used as an important material in waterproofing projects for various permanent structures such as roofs, basements, basements, and pools. To ensure their quality, many indicators must be tested before use. As a material that plays a seepage prevention role, impermeability is undoubtedly a crucial indicator, and testing this indicator requires the use of impermeability testing.

[0003] Traditional testing equipment can only perform waterproofing tests on local areas of waterproof membranes in actual use. This testing method cannot comprehensively test the waterproofing of the membranes, and the test results are not accurate enough. At the same time, when conducting comprehensive testing on large areas of membranes, traditional testing equipment requires manual movement and replacement of the membranes, which is cumbersome, inefficient, and impractical. Summary of the Invention

[0004] This invention provides a waterproof membrane testing frame, which solves the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A waterproof membrane testing frame includes a mounting plate and supports on both sides of the bottom of the mounting plate, with crossbars fixedly connected to the bottom of the supports. A testing mechanism is disposed between the supports, including a rotating column rotatably disposed between the crossbars, a mounting roller fixedly sleeved on the rotating column, mounting arms fixedly connected to the mounting rollers, a fixed frame fixedly connected to the end of the mounting arms away from the mounting rollers, transmission rollers rotatably connected to both sides of the fixed frame, waterproof membrane disposed between the transmission rollers, a recycling trough fixedly connected to the mounting rollers between the mounting arms, a support roller rotatably connected to the recycling trough, a drive housing fixedly connected to the side wall of one support on one side of the rotating column, a drive assembly disposed within the drive housing, a movable rod slidably sleeved on the support above the mounting rollers, a telescopic cylinder connected to the bottom of the movable rod, an elastic element sleeved at one end of the telescopic cylinder, and a testing assembly disposed at the bottom of the telescopic cylinder.

[0007] As a preferred embodiment of the present invention, the drive assembly includes a drive motor fixedly disposed on the inner wall of the drive housing, an incomplete gear fixedly connected to the end of the output shaft of the drive motor, a linkage gear rotatably connected to the inner wall of the drive housing below the incomplete gear, the linkage gear meshing with the incomplete gear, and the axial shaft of the linkage gear passing through the drive housing at one end and fixedly connected to the rotating column at the other end.

[0008] As a preferred embodiment of the present invention, one end of the shaft of the incomplete gear is fixedly connected to a transmission wheel, one side of the transmission wheel is hinged to a transmission rod, one end of the transmission rod is hinged to a movable block, the movable block is slidably disposed in the drive housing, the top of the movable block is fixedly connected to a drive rod, one end of the drive rod passes through the top wall of the drive housing, and the top of the drive rod is fixedly connected to the movable rod.

[0009] As a preferred embodiment of the present invention, the detection component includes a water tank fixedly disposed at the bottom of the telescopic cylinder, a permeable plate slidably sleeved at the bottom end of the water tank, a telescopic component fixedly connected between the permeable plate and the water tank, and a sealing plate fixedly connected inside the water tank.

[0010] As a preferred embodiment of the present invention, a valve pipe is slidably disposed through the sealing plate, the bottom of the valve pipe is fixedly connected to the permeable plate, and a valve groove is formed on the valve pipe, which passes through the permeable plate.

[0011] As a preferred embodiment of the present invention, the movable rod is fixedly connected to the side wall of the toothed rod, and the fixed frame side wall below the toothed rod is rotatably connected to the transmission gear. One end of the shaft of the transmission gear is fixedly connected to the end of the shaft of the transmission roller.

[0012] As a preferred embodiment of the present invention, a detection rod is fixedly installed through the side wall of the recycling tank, allowing operators to conveniently observe whether there is water in the recycling tank.

[0013] This invention has the following advantages: In use, the waterproof membrane to be tested is placed on the transmission rollers on both sides of the device. Then, the drive motor is started, driving the incomplete gear to rotate. The incomplete gear drives the transmission wheel to rotate, which in turn drives the drive rod above the movable block to move up and down under the action of the transmission rod. Under the action of the movable rod, the telescopic cylinder moves down. When the permeable plate contacts the waterproof membrane, it drives the waterproof membrane to move down. When the permeable plate contacts the support roller, it moves up relative to the water tank, thereby driving the valve pipe to move up. The valve groove on the valve pipe moves above the sealing plate and communicates with the water tank. Water in the water tank flows out from the valve groove and contacts the waterproof membrane. When the movable rod continues to move down, the telescopic cylinder... As the roll retracts, the rack and pinion mesh with the transmission gear, driving the transmission roller to rotate. The transmission roller then rewinds the waterproof membrane, ensuring close contact between the permeable sheet and the waterproof membrane. During the membrane's movement, it comes into contact with water within the permeable sheet. If leakage occurs, the water will fall into the recovery trough. Operators can observe and assess the waterproof performance of the entire membrane using the detection rod. After one roll is tested, the incomplete gear meshes with the linkage gear, causing the rotating column to rotate intermittently, which in turn causes the installation roller to rotate intermittently to replace the material. Then, another roll is tested for its waterproof performance. This method of testing provides better results, more comprehensive coverage, flexible and convenient operation, and greater accuracy.
