[0002] Concrete anti-seepage wall is a wall-shaped anti-seepage building made of concrete. Its anti-seepage performance determines the quality of the anti-seepage wall. The so-called anti-seepage performance refers to the performance of the materials used in the building to resist water or other penetration under pressure. Due to the particularity of concrete anti-seepage wall in application, the anti-seepage performance test of concrete anti-seepage wall is very important.

[0003] In the related technology, where the concrete anti-seepage wall is constructed, the concrete used for its construction can be tested for anti-seepage (generally speaking, more than 6 concrete specimens can be prefabricated). After the specimens are prepared, the staff will wipe off the moisture on the specimens, and then use a wire brush to remove impurities on the surface of the specimens, and then apply a layer of sealing material on the surface of the specimens. After that, the specimens are placed in the test mold, and then the test mold with the specimens is installed on the concrete anti-seepage instrument for testing.

[0004] Regarding the above-mentioned relevant technical features, there are but are not limited to the following defects: 1. Manual methods are used to process the test pieces, but when too many samples need to be tested, the test efficiency of the test pieces will be reduced; 2.

[0052] In some embodiments of the present disclosure, the clamping portion 2454 includes a clamping bidirectional screw 24541, a clamping motor 24542, a carrier plate 24543 and a plurality of arc plates 24544; the carrier plate 24543 is rotatably connected to the second section 2452, and the clamping bidirectional screw 24541 is rotatably connected to the carrier plate 24543; the clamping bidirectional screw 24541 has a positive thread segment and a negative thread segment; a plurality of arc plates 24544 are respectively arranged on the positive thread segment and the negative thread segment of the clamping bidirectional screw 24541, and the arc plates 24544 form a clamping space for the end of the specimen 10; the clamping motor 24542 is used to drive the clamping bidirectional screw 24541 to rotate.

[0053] Furthermore, in the embodiment of the present disclosure, a second rotating motor (not specifically marked in this application) for driving the rotation between the clamping portion 2454 and the second section 2452 may also be included; the housing of the second rotating motor is installed on the second section 2452, the carrier plate 24543 is connected to the output shaft of the second rotating motor, and the second rotating motor is used to drive the carrier plate 24543 to rotate.

[0054] In some embodiments of the present disclosure, the impurity removal mechanism 4 includes an impurity removal box 41, an impurity removal plate 42 and an impurity removal steel brush 43; the impurity removal box 41 is installed on one side of the wiping bracket 31; the impurity removal plate 42 is detachably arranged on the impurity removal box 41, and the impurity removal plate 42 divides the impurity removal box 41 into an impurity processing chamber and an impurity collecting chamber; the impurity removal steel brush 43 is installed on the impurity removal plate 42 and is located in the impurity processing chamber; the impurity removal plate 42 has a drop hole 421 for impurities to fall; wherein the gripping mechanism 2 has an end face cleaning state; in the end face cleaning state, on the clamping assembly 24, the clamping portion 2454 on the second section 2452 of any clamping plate 245 releases the specimen 10, and the plane where the second section 2452 of another adjacent clamping plate 245 is located is parallel to the plane where the impurity removal plate 42 is located, and the end face of the specimen 10 contacts the impurity removal steel brush 43.

[0055] It can be understood that in the embodiment of the present disclosure, in order to remove impurities from the side and end faces of the specimen 10, the specimen 10 needs to be subjected to posture adjustment processing. For example, when in the side posture, the surrounding side of the specimen 10 can be subjected to impurity removal processing; when in the end posture, the end face of the specimen 10 can be subjected to impurity removal processing.

[0056] Specifically, in the side posture, the first motor 243 drives the first one-way screw 241 to rotate, and the first one-way screw 241 drives the clamping plate 245 provided thereon to move, and the second motor 244 drives the second one-way screw 242 to rotate, and the second one-way screw 242 drives the clamping plate 245 provided thereon to move, and the two clamping plates 245 clamp the end face of the test piece 10, and the axial direction of the test piece 10 is the same as the axial direction of the wipe-drying roller 32, so as to facilitate the removal of impurities from the side face of the test piece 10. In the end face rotation state, since the test piece 10 needs to be adjusted to a vertical state (the axial direction of the test piece 10 is perpendicular to the axial direction of the wipe-drying roller 32), the clamping plate 245 on the first one-way screw 241 or the clamping plate 245 on the second one-way screw 242 needs to be avoided so that the posture of the test piece 10 can be adjusted.

[0057] Here, the avoidance of the clamping plate 245 on the first one-way screw 241 is taken as an example (of course, the clamping plate 245 on the second one-way screw 242 can also be avoided so that the two end surfaces of the test piece 10 can be cleaned): When the clamping plate 245 on the first one-way screw 241 is to avoid, the first one-way screw 241 can be opened first, and the first one-way screw 241 rotates to drive the clamping plate 245 to move, and the clamping plate 245 is away from the clamping plate 245 set on the second one-way screw 242. At this time, the space between the two clamping plates 245 becomes larger, which can make the test piece 10 perform posture adjustment. When performing posture adjustment, the clamping part 2454 is first opened, and the clamping part 2454 clamps the end face of the test piece 10 again, and the rotating part 2453 is opened, and the rotating part 2453 drives the second section 2452 to move on the first section 2451. When the plane where the second section 2452 is located is parallel to the plane where the impurity removal plate 42 is located, the posture adjustment of the test piece 10 is achieved, so that the end face of the test piece 10 can be removed.

[0058] See also Figure 1 , Figure 7 In some embodiments of the present disclosure, the smearing mechanism 5 includes a smearing frame 51, a smearing roller 52, a heating unit 53 and a smearing motor 54; the smearing frame 51 is installed on the side of the impurity removal box 41 away from the wiping bracket 31, and the sealing material is placed in the smearing frame 51; the smearing roller 52 is rotatably connected to the smearing frame 51, and the smearing roller 52 can contact the sealing material in the smearing frame 51; the heating unit 53 is provided on the smearing frame 51, and is used to heat the sealing material in the smearing frame 51; the smearing motor 54 is used to drive the smearing roller 52 to rotate.

[0059] It is understandable that the sealing material can be liquid paraffin. When the liquid paraffin is placed in the coating frame 51, the liquid paraffin may solidify when the temperature is low. By turning on the heating part 53, the heating part 53 can heat the coating frame 51 to melt the liquid paraffin, and then the melted liquid paraffin can be coated on the side of the specimen 10 through the coating roller 52.

[0060] As an example, the heating part 53 may be a heating wire (not specifically shown in the drawings of the present application). By energizing the heating wire, the heating wire generates heat, thereby melting the liquid paraffin on the coating frame 51 .

[0062] Similarly, as mentioned above, when the test piece 10 needs to be pressurized into the test mold 9 through the pressurizing mechanism 6, the test piece 10 also needs to be adjusted from the side posture to the end posture (because the test piece 10 is in this face posture during pressurization), which is not described in detail here.

[0063] As an example, the second moving part 64 may include a second moving screw 641 and a second moving motor 642; the second moving screw 641 is threadedly connected to the detection bracket 1, and the axial direction of the second moving screw 641 is the same as the axial direction of the first moving screw 222; the base of the pressurizing cylinder 62 is threadedly connected to the second moving screw 641, and the pressurizing cylinder 62 is slidingly connected to the detection bracket 1; the second moving motor 642 is used to drive the second moving screw 641 to rotate.

Specifically, the specimen 10 can be placed between adjacent wipe dry rollers 32, and the wipe dry motor 35 is turned on.

At this time, the space between the two clamping plates 245 becomes larger, which enables the specimen 10 to adjust its posture. When adjusting the posture, first open the clamping part 2454, the clamping part 2454 clamps the end face of the specimen 10 again, open the rotating part 2453, and the rotating part 2453 drives the second section 2452 to move on the first section 2451.
