Description

Technical Field

[0001] This utility model relates to the field of testing technology, and in particular to a quality testing device for waterproof membrane. Background Technology

[0002] Waterproof membrane is a flexible building material that can be rolled up. It is mainly used in building walls, roofs, tunnels, highways, and other locations to resist external rainwater and groundwater seepage, forming the first line of defense in waterproofing projects. When laying waterproof membrane, especially at complex joints, corners, and pipe roots, it is unavoidable to stretch, bend, and press the material. Tensile testing (especially tensile strength testing) can measure the membrane's ability to resist the tensile forces generated during these construction operations. If the tensile strength is insufficient, the material may tear or be damaged during construction, leading to waterproofing failure. When conducting tensile testing, the waterproof membrane must first be clamped before the test is performed.

[0003] In the existing technology, the clamping and stretching of waterproof membrane is driven by two different power sources, which makes the structure of the entire testing device more complex and the manufacturing cost more expensive, making it difficult to meet people's needs. Utility Model Content

[0004] The purpose of this utility model is to provide a quality testing device for waterproof membranes to solve the problem of complex structures.

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

[0006] A waterproof membrane quality inspection device includes a base plate, on which a movable frame is slidably mounted. Two pairs of clamping plates are provided between the movable frames, wherein the upper pair of clamping plates is slidably connected to the movable frames, and the lower pair of clamping plates is fixedly connected to the movable frames. The movable frames are provided with limiting components for restricting the upward movement of the upper clamping plates. A fixed frame is fixedly installed on the base plate, and the fixed frame is provided with a power component for driving the clamping plates to clamp the waterproof membrane and driving the movable frames to move away from each other. A limiting component is provided above the base plate for restricting the movement of the pair of movable frames.

[0007] As a further description of the above technical solution: the clamping plate is provided with protrusions, and the upper and lower protrusions are staggered.

[0008] As a further description of the above technical solution: the power assembly includes a connecting rod rotatably mounted on the clamping plate, a round rod fixedly mounted on the output end of the cylinder, and a first spring fixedly mounted inside the cylinder. The connecting rods are rotatably connected to each other. The cylinder is fixedly mounted on a fixed frame. A horizontal plate is slidably connected to the round rod, and the horizontal plate is rotatably connected to the connecting rod. The round rod passes through the cylinder and is fixedly connected to the upper end of the first spring. The upper end of the cylinder is fixedly connected to the lower end face of the horizontal plate.

[0009] As a further description of the above technical solution: the limiting component includes a movable block slidably installed in the slider and a card plate fixedly installed in the movable frame. The slider is slidably installed in the movable frame, and a second spring is provided between the movable blocks.

[0010] As a further description of the above technical solution: the limiting component includes a fixed plate fixedly mounted on the movable frame, and a circular locking block installed between a pair of fixed plates, wherein the circular locking block is located directly below the circular rod.

[0011] As a further description of the above technical solution: an industrial camera is fixedly mounted on the mounting bracket, and scale lines are provided on the base plate.

[0012] As a further description of the above technical solution: an extension plate is fixedly installed on the movable block.

[0013] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0014] 1. Place the waterproof membrane between the clamping plates. The power unit drives the upper clamping plate to move until the waterproof membrane is completely clamped. The power unit continues to move until it drives the movable frame to disengage from the limiting component. The power unit continues to move and drives the movable frame to move to both sides of the base plate to stretch the waterproof membrane and test its tensile strength. Throughout the process, the power unit provides the power to clamp and stretch the waterproof membrane, optimizes the structure of the device, and reduces manufacturing costs.

[0015] 2. During the clamping process of the waterproof membrane, the clamp drives the slider and movable block to move downwards. The movable block engages with the groove on the clamp in sequence. Since the upper end face of the movable block is horizontal and the lower end face is inclined, the movable block can only move downwards along the clamp. After the waterproof membrane is clamped and stabilized, the movable block will limit the clamp. During the entire testing process, the waterproof membrane will not loosen. Moreover, the staggered protrusions of the clamp can enhance the clamping effect and prevent slippage. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example: This example provides a waterproof membrane quality inspection device, see [link to example]. Figure 1 - Figure 6 Specifically, the base plate 1 has a movable frame 12 slidably mounted on it, and two pairs of clamping plates 13 are provided between the movable frames 12. The upper pair of clamping plates 13 is slidably connected to the movable frame 12, and the lower pair of clamping plates 13 is fixedly connected to the movable frame 12. The movable frame 12 is provided with a limiting component for restricting the upper clamping plate 13 from moving upward. A fixed frame 11 is fixedly mounted on the base plate 1. The fixed frame 11 is provided with a power component for driving the clamping plates 13 to clamp the waterproof membrane and driving the movable frame 12 to move away from each other. A limiting component is provided above the base plate 1 for restricting the movement of the pair of movable frames 12.

[0026] The waterproof membrane is placed between the clamping plates 13. The power component drives the upper clamping plate 13 to move until the waterproof membrane is completely clamped. The power component continues to move until the power component drives the movable frame 12 to disengage from the limiting component. The power component continues to move and drives the movable frame 12 to move to both sides of the base plate 1 to stretch the waterproof membrane and test the tensile strength of the waterproof membrane. Throughout the process, the power component provides the power to clamp and stretch the waterproof membrane, thus optimizing the structure of the device.

[0027] The power assembly includes a connecting rod 2 rotatably mounted on the clamping plate 13, a round rod 22 fixedly mounted on the output end of the cylinder 21, and a first spring 25 fixedly mounted inside the cylinder 24. The connecting rods 2 are rotatably connected to each other. The cylinder 21 is fixedly mounted on the fixed frame 11. A horizontal plate 23 is slidably connected to the round rod 22, and the horizontal plate 23 is rotatably connected to the connecting rod 2. The round rod 22 passes through the cylinder 24 and is fixedly connected to the upper end of the first spring 25. The upper end of the cylinder 24 is fixedly connected to the lower end face of the horizontal plate 23. The limiting assembly includes a movable block 31 slidably mounted in the slider 3 and a locking plate 32 fixedly mounted in the movable frame 12. The slider 3 is slidably mounted in the movable frame 12. A second spring 33 is provided between the movable blocks 31. The limiting assembly includes a fixed plate 5 fixedly mounted on the movable frame 12 and a circular locking block 51 installed between a pair of fixed plates 5. The circular locking block 51 is located directly below the round rod 22.

[0028] Cylinder 21 drives the round rod 22 and cylinder 24 to move downward together. Cylinder 24 drives the horizontal plate 23 to move downward. Horizontal plate 23 drives the upper clamping plate 13 to move downward through connecting rod 2 until clamping plate 13 pre-clamps the waterproof membrane. Then, the round rod 22 and cylinder 24 continue to move downward. The round rod 22 drives the cylinder 24 to move a short distance through the first spring 25 until clamping plate 13 firmly clamps the waterproof membrane. Cylinder 24 stops moving. The round rod 22 continues to move downward until the lower end of the round rod 22 contacts the circular locking block 51. The round rod 22 squeezes the circular locking block 51 away from the fixed plate 5, so that the pair of movable frames 12 will not restrict each other. The round rod 22 continues to move downward. The round rod 22 drives clamping plate 13 and movable frame 12 to move to both sides of the bottom plate 1 through cylinder 24 and connecting rod 2. During this process, clamping plate 13 clamps the waterproof membrane, and movable frame 12 stretches the waterproof membrane to test the tensile strength of the waterproof membrane.

[0029] Among them, the clamping plate 13 clamps two pieces of waterproof membrane at one time, located on both sides of the round rod 22 respectively, so that two sets of data can be obtained from one side of the experiment, thus improving efficiency;

[0030] During the process of clamping the waterproof membrane by the clamping plate 13, the clamping plate 13 drives the slider 3 and the movable block 31 to move downward. The movable block 31 engages with the groove on the clamping plate 32 in sequence. Since the upper end face of the movable block 31 is horizontal and the lower end face is inclined, the movable block 31 can only move downward along the clamping plate 32. After the waterproof membrane is clamped and stabilized, the movable block 31 will limit the clamping plate 13. During the entire testing process, the waterproof membrane will not loosen. Moreover, the staggered protrusions of the clamping plate 13 can enhance the clamping effect and prevent slippage.

[0031] It should be noted that: the circular locking block 51 is initially locked between a pair of fixed plates 5 by friction. During the clamping process of the clamping plate 13, due to the inclined setting of the connecting rod 2, the movable frame 12 tends to move to both sides of the bottom plate, which increases the friction between the circular locking block 51 and the fixed plate 5. The circular locking block 51 will not fall off until the pushing force of the circular rod 22 is greater than the friction, at which point the circular locking block 51 will detach from the fixed plate 5 and fall onto the bottom plate 1.

[0032] An industrial camera 6 is fixedly mounted on the mounting bracket 11, and scale lines 61 are provided on the base plate 1;

[0033] The industrial camera 6 records the position of the movable frame 12 relative to the scale line 61 when the waterproof membrane is just stretched straight, and then records the position of the movable frame 12 relative to the scale line 61 when the waterproof membrane is just completely broken. By comparing the two positions, the tensile strength of the waterproof membrane can be analyzed. It should be noted that since the two movable frames 12 move symmetrically, the industrial camera 6 only needs to record the movement distance of one side of the movable frame 12.

[0034] An extension plate 4 is fixedly installed on the movable block 31;

[0035] After the test is completed, pinch the extension plate 4 towards the middle by hand. The extension plate 4 will cause the movable block 31 to break free from the restriction of the clamping plate 32, and the clamping plate 13 can then loosen the waterproof membrane. The waterproof membrane can then be removed for the next test.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
