Description

Technical Field

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

[0002] A permeameter is a device used to test the permeability of concrete. This instrument can be used to test the impermeability of concrete and determine its impermeability grade.

[0003] In the prior art, a search revealed a Chinese patent disclosing "A Permeameter for Testing the Quality of Building Engineering," application number "202320070834.4." This patent mainly includes a permeameter body, with a test mold on the upper surface, a regulating valve on the front surface, a control panel fixedly mounted on the front surface, and a pressing mechanism at the upper end. This pressing mechanism includes a docking base, a connecting armature, a pressing plate, a positioning slot, and a docking screw hole. A connecting mechanism is fixedly mounted inside the permeameter body, including a mounting base, a mounting groove, an electromagnet, a mounting screw hole, and a mechanism housing. The mounting base is fixedly mounted on the permeameter body. While this permeameter allows for quick installation of the test mold onto the permeameter body... However, the aforementioned permeameter requires repeated lifting and moving of the test mold and pressure plate when loading and unloading samples. The weight of multiple test molds and pressure plates not only increases labor intensity and operation time but may also lead to operator fatigue due to prolonged repetitive work, thus affecting the accuracy and efficiency of the test. Furthermore, repeated lifting and moving of the test mold and pressure plate may also cause safety issues; improper operation may cause the test mold and pressure plate to detach or collide, potentially causing injury to the operator and equipment. Therefore, this utility model provides a permeameter for engineering quality testing to solve the problems mentioned in the background art. Utility Model Content

[0021] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0022] Reference Figure 1-4 This utility model discloses a permeameter for engineering quality testing, which includes a permeameter body 1 and a test mold 2 located on the top of the permeameter body 1. Guide rails 3 are fixedly connected to the top of the permeameter body 1 and on both sides of the test mold 2. Each guide rail 3 has a trapezoidal groove 8 on its top side. A trapezoidal positioning block 5 is slidably connected inside each groove 8. A U-shaped movable frame 4 is fixedly connected to the top of the positioning block 5. The bottom end of the movable frame 4 is slidably connected to the top of the guide rail 3. A nut 9 is fixedly connected to the top side of the movable frame 4. A connecting rod 6 is movably connected to the inside of the nut 9. The connecting rod 6 has a threaded structure that mates with the nut 9 on the side near the top and bottom. A handwheel 7 is fixedly connected to the top of the connecting rod 6. The bottom end of the connecting rod 6 is rotatably connected to the top of the test mold 2.

[0023] The installation and separation of the test mold 2 from the permeameter body 1 are mainly achieved through the structure of connecting rod 6, movable frame 4, and guide rail 3. When the test mold 2 needs to be installed on top of the permeameter body 1, the movable frame 4 is located above the testing area. Rotating the handwheel 7 drives the connecting rod 6 and the test mold 2 at its bottom to move downwards. After the test mold 2 is in contact with the top of the permeameter body 1, the test mold 2 can be installed on top of the permeameter body 1 through the engagement of the threaded structure of the connecting rod 6 and the nut 9, and the engagement of the positioning block 5 and the slide groove 8. After the test is completed, rotating the connecting rod 6 and lifting it upwards moves the test mold 2 above the sample. The test mold 2 can then be positioned by the engagement of the threaded structure of the connecting rod 6 and the nut 9. Moving the test mold 2 to one side of the sample allows for sample loading and unloading. The operation is simple, avoiding the troublesome problem of repeatedly lifting and moving the test mold 2 when loading and unloading samples. It is more convenient and faster to use, simplifying the test mold 2 loading and unloading process, reducing the workload of testing personnel, and helping to improve the safety and efficiency of testing.

[0024] The movable frame 4 has two guide rods 10 symmetrically slidably connected inside. The top of each guide rod 10 is fixedly connected to an end plate 11. Springs 12 are sleeved on the outside of each guide rod 10 and located at the top of the movable frame 4. The bottom of each guide rod 10 is fixedly connected to the test mold 2. When the test mold 2 moves up and down, it moves more stably under the action of the guide rods 10. When the test mold 2 moves to the top of the permeameter body 1, the springs 12 can act as a buffer to prevent the falling test mold 2 from colliding with the permeameter body 1.

[0025] A handle 13 is fixedly connected to the front side of the test mold 2 to facilitate the operation of the test mold 2 by the testing personnel to move it up and down. The top of the handwheel 7 is provided with a rotating handle that is perpendicular to the top of the handwheel 7. The rotating handle is rotatably connected to one side of the top of the handwheel 7 to facilitate the operation of the handwheel 7 by the testing personnel.

[0026] It also includes a regulating valve 14 and a control panel 15, both of which are located on the front side of the permeameter body 1. The testing personnel can adjust the working status of the permeameter through the regulating valve 14 and the control panel 15.

[0027] Working Principle: The sealing and separation of the test mold 2 from the permeameter body 1 is mainly achieved through the structure of connecting rod 6, movable frame 4, and guide rail 3. When the test mold 2 needs to be installed on top of the permeameter body 1, the movable frame 4 is located above the testing area. Rotating the handwheel 7 drives the connecting rod 6 and the test mold 2 at its bottom to move downwards. After the test mold 2 is in contact with the top of the permeameter body 1, the test mold 2 is sealed to the top of the permeameter body 1 through the engagement of the threaded structure of the connecting rod 6 and the nut 9, as well as the engagement of the positioning block 5 and the slide groove 8. After the test is completed, rotating the connecting rod 6 and lifting it upwards moves the test mold 2 above the sample. The threaded structure of the connecting rod 6 and the nut 9 then position the test mold 2. Moving the test mold 2 to one side of the sample allows for sample loading and unloading. The operation is simple, avoiding the troublesome problem of repeatedly lifting and moving the test mold 2 when loading and unloading samples. It is more convenient and faster to use, simplifying the test mold 2 loading and unloading process, reducing the workload of testing personnel, and helping to improve the safety and efficiency of testing.
