Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a concrete anti-permeability instrument. Background Art

[0002] Concrete impermeability tester is used to test the concrete impermeability performance and determine the impermeability grade. Therefore, it is widely used in relevant production, construction, design, teaching and research departments. The concrete impermeability tester is designed according to the hydraulic principle. The motor drives the water pump to apply pressure. It is connected with the pressure vessel, control valve, test mold seat, etc. through pipelines. The pressure is output by the water pump into the pressure vessel and then transported to each test piece system for loading test. The pipeline is equipped with an electric contact pressure gauge and an electrical control system. By adjusting the electric contacts in the electric contact pressure gauge, the pressure can be kept within the specified range of 0.1-4Mpa for constant pressure test.

[0003] For example, a Chinese patent (publication number: CN213181167U) discloses a concrete impermeability tester, a field of concrete testing equipment, including a base, a plurality of bases are arranged on the upper surface of the base, a test mold is arranged on the base, a plurality of control valves for controlling water pressure are arranged on one side of the base, and the plurality of control valves are arranged in a straight line, the control valve includes a valve stem and a turntable, one end of the valve stem extends into the interior of the base, the other end of the valve stem protrudes from one side of the base, and the valve stem is rotatably assembled on the base, the turntable is arranged at the end of the valve stem protruding from the base, a clamping device is vertically slidably assembled inside the base, and the clamping device is located at the upper and lower sides of the end of the valve stem extending into the interior of the base, a control button is arranged on the outer side of the base, the control button controls the opening and closing of the clamping device to clamp a row of valve stems, and the valve stem of the control valve is clamped by the clamping device, and the valve stem cannot be easily rotated, which has the effect of not affecting the test results and test accuracy.

[0004] The above concrete impermeability tester still has certain shortcomings. The test mold sleeve can be quickly, easily and accurately installed in the test mold seat by cooperating the clamping ring of the test mold seat with the boss of the test mold sleeve and the clamping ring of the test mold seat with the boss of the test mold sleeve. However, since the test mold seat and the test mold are tightened by multiple bolts, during the test process, the tester needs to repeatedly tighten the bolts. Since multiple groups of test molds need to be installed and disassembled one by one, it is very inconvenient and the test efficiency is low. Therefore, a concrete impermeability tester is proposed to solve the above problems. Utility Model Content

The utility model is mainly used to protect mechanical devices, so the utility model will no longer explain the control method and circuit connection in detail.

[0045] The working principle of the above embodiment is:

[0046] (1) After the trial mold base 4 and the base 3 are installed, the first motor 502 is started. The first motor 502 drives the first rotating rod 503 to rotate, and the first rotating rod 503 drives the plurality of first gears 504 to rotate. The first gear 504 drives the second gear 505 and the first screw rod 507 to rotate together. Since the two threads of the first screw rod 507 are in opposite directions, the first screw rod 507 rotates to drive the two moving blocks 508 to move relative to each other at the same time. The moving blocks 508 slide on the outer surface of the sliding rod to increase the stability of the moving blocks 508 when they move. The moving blocks 508 drive the clamping blocks 509 to move together, and the trial mold base 4 is fixed by the clamping blocks 509, thereby improving the stability and efficiency of the installation.

[0047] (2) When the base 1 needs to be used, the dual-axis motor 201 is started. The dual-axis motor 201 drives the second rotating rod 202 and the first bevel gear 203 to rotate together. The first bevel gear 203 drives the second bevel gear 204 and the second screw rod 205 to rotate together. The second screw rod 205 drives the movable block 206 to move. The movable block 206 slides on the limit rod to increase the stability of the movable block 206 when it moves. When the movable block 206 moves, it drives the connecting block 207 to move together. The protective shell 208 is driven downward by the connecting block 207 to facilitate the use of the operator 6. Conversely, the protective shell 208 protects the operator 6 to prevent the operator 6 from being accidentally touched.
