Description

Technical Field

[0001] The utility model belongs to the technical field of concrete performance detection, and specifically relates to a concrete anti-permeability supervision and detection device. Background Art

[0002] Concrete is a material widely used in construction projects. During the use of concrete, due to the influence of environmental factors such as temperature and humidity, water seepage and other problems may occur. In order to ensure the use effect and service life of concrete, it is necessary to test the impermeability of concrete. The existing testing method usually places multiple truncated cone-shaped concrete specimens into a test mold, fixes multiple test molds on the surface of an impermeability tester at the same time, and injects water from the bottom to observe the water seepage on the top of the specimen. When fixing the test mold, it is usually necessary to pass multiple sets of bolts through the test mold and insert it into the impermeability tester, which is a relatively complicated operation.

[0003] A Chinese patent with publication number CN214749641U discloses a device for monitoring the anti-seepage performance of concrete. The solution includes a frame, a test mold and a clamping assembly. The clamping assembly includes a bracket, a pressure plate and a driving component. The above solution uses a driving component to drive the pressure plate to descend and simultaneously clamp multiple test mold seat trays. There is no need to tighten multiple sets of bolts on each test mold, which reduces the operating steps of installing and disassembling the test mold and improves work efficiency.

[0004] After completing one test, the above scheme needs to lift the pressure plate to remove the test mold that has completed the experiment, and install a new test mold before the next experiment. When the pressure plate is lifted, it will continue to hang horizontally above the frame, resulting in a relatively narrow vertical space between the top of the frame and the pressure plate, which is inconvenient for the test personnel to remove and place the test mold. Utility Model Content

[0005] The utility model aims to provide a concrete impermeability supervision and detection device, so as to facilitate detection personnel to remove and place test molds.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A concrete impermeability monitoring and testing device comprises an impermeability tester body, a driving mechanism, a clamping assembly and an elastic component. A plurality of bases for placing test molds are arranged on the top of the impermeability tester body. Support frames are fixedly arranged on the left and right sides of the top of the impermeability tester body, respectively. A slide groove is arranged on the side close to each other of the two support frames, and a slider is slidably arranged in the slide groove. The two sliders are rotatably connected with connecting rods on the side close to each other. The driving mechanism is arranged in the slide groove and can drive the slider to move up and down. The clamping assembly is arranged below the slider. The clamping assembly comprises a pressing plate. A plurality of through holes cooperating with the test molds are arranged on the top of the pressing plate. One end of the connecting rod is rotatably connected to the pressing plate at the front side of the side wall of the pressing plate. The slider can drive the pressing plate to descend. The elastic component is arranged between the impermeability tester body and the clamping assembly and can drive the pressing plate to rise.

[0008] The principle and effect of this technical solution:

[0009] When the slider is in contact with the top wall of the slide groove, the elastic member supports the clamping assembly so that the clamping assembly is located above the test mold. At this time, the pressure plate is in an inclined state, and the projection surface of the pressure plate is located between multiple bases, driving the driving mechanism to work and moving the slider downward. As the slider moves relative to the clamping assembly, the connecting rod pushes the pressure plate to rotate. When the slider is in contact with the clamping assembly, the pressure plate is in a horizontal state. When the slider continues to move downward, it pushes the clamping assembly to move downward. As the slider is stationary relative to the clamping assembly, the pressure plate does not rotate until the pressure plate clamps the test mold and the installation work is completed. After the measurement is completed, move the slider upward, and the elastic mechanism pushes the clamping assembly to rise and remain stationary relative to the slider. When the gravity of the clamping assembly is equal to the elastic force of the elastic member, the clamping assembly no longer rises, the slider moves relative to the clamping assembly, and the connecting rod pulls the pressure plate to rotate in the opposite direction until the top of the slider is in contact with the top wall of the slide groove.

[0010] Through the above arrangement, the pressing plate can press multiple test molds at the same time. After the pressing plate is lifted, it can automatically rotate until the projection surface of the pressing plate is located between the multiple bases, so as to avoid the pressing plate being continuously hung above the base, making it convenient for the inspection personnel to remove and place the test molds.

[0011] In the utility model, the front and rear side walls of the two support frames are fixedly provided with protrusions, and guide rods are fixedly provided between the protrusions and the main body of the anti-seepage instrument. The clamping assembly also includes a relay plate, which is slidably inserted into the front and rear side walls of the slide groove under the slider, and the front and rear ends of the relay plate are respectively slidably mounted on the guide rods, and the relay plate is rotatably connected to the pressure plate.

[0012] In the utility model, the elastic component is configured as a compression spring, and the compression spring is sleeved on the outer periphery of the guide rod between the relay plate and the main body of the anti-seepage instrument.

[0013] In the utility model, the driving mechanism includes a motor and a threaded rod. The motor is fixedly arranged below the slide slot. The threaded rod is inserted into the slide slot along the vertical rotation and is transmission-connected to the output shaft of the motor. The slider is fitted on the threaded rod, and the side wall of the slider is slidably abutted against the slide slot. The relay plate is slidably mounted on the threaded rod.

[0014] The principle and effect of this technical solution:

[0015] The motor is driven to drive the threaded rod to rotate. Since the slide groove limits the rotation of the slider, the slider moves downward with the rotation of the threaded rod. At this time, the gravity of the clamping assembly is equal to the sum of the elastic forces of multiple compression springs, and the relay plate does not move. The connecting rod pushes the pressure plate to rotate. When the slider abuts the relay plate, the pressure plate is in a horizontal state. The threaded rod continues to rotate, and the slider pushes the relay plate to move downward together and compresses the compression spring to make it have elastic force. During the downward movement of the relay plate, the pressure plate continues to be horizontal until the pressure plate presses the test mold.

[0016] Through the above arrangement, the purpose of automatically rotating the pressing plate to a horizontal position when the pressing plate moves downward and automatically rotating the pressing plate to a position where the projection surface is located between the plurality of bases after being lifted up is achieved.

[0017] In the present invention, when the top of the sliding block abuts against the top wall of the sliding groove, the length direction of the connecting rod forms an angle with the vertical plane. Through the above arrangement, the connecting rod can be easily rotated, thereby improving the practicality of the present invention.

[0018] In the utility model, a pressure block is fixedly arranged at the rear end of the top of the relay plate near the pressure plate. When the slider abuts against the relay plate, the pressure plate is in a horizontal state and abuts against the bottom of the pressure block. Through the above arrangement, on the one hand, excessive rotation of the pressure plate can be avoided to ensure that the pressure plate is in a horizontal state, and on the other hand, the force on the pressure plate can be more balanced.

[0019] In the utility model, an elastic gasket is fixedly arranged at the bottom of the pressing plate at the periphery of the through hole. Through the above arrangement, it can be avoided that the pressing plate cannot press multiple test molds at the same time due to different degrees of wear of each test mold.
