Description

Technical Field

[0001] The utility model relates to the technical field of concrete anti-seepage test, and more specifically, to a sealing device used for concrete anti-seepage test. Background Art

[0002] Concrete is a cement concrete made by mixing cement as a gelling material, sand and stone as aggregates and water in a certain proportion. It is widely used in the field of civil engineering. In order to ensure the density of concrete samples when using them, it is necessary to carry out a water-resistance test on the concrete samples. When carrying out a water-resistance test on concrete samples, it is particularly important to seal the concrete samples.

[0003] There are generally two ways to seal concrete samples. One is to use paraffin wax to seal, and the other is to use cement and butter to seal. According to the above two methods, many auxiliary equipment are used, the test mold needs to be heated, which is dangerous, and the temperature is not easy to control. The concrete sample is pressed into the test mold preheated by an oven or an electric furnace, and the pressure can only be released after the test mold becomes cold. This takes a long time to install the test piece and is inefficient.

[0004] For example, the utility model patent with patent publication number CN214224889U discloses a concrete impermeability test sealing device, including a concrete sample, a base and a tray for placing the concrete sample. The technical solution of this structure adopts a turntable to rotate and use a glue gun to spray sealant on the concrete sample, and then wrap the surface of the concrete sample with a fresh-keeping film after the spraying is completed. Compared with the traditional concrete impermeability test sealing device, it requires less auxiliary equipment, and compared with the use of paraffin sealing, it has less preheating steps, which reduces the sealing installation time of the concrete sample.

[0005] However, when this structure is actually used, when spraying sealant on concrete samples, the concrete samples need to be moved to a pallet. Since concrete samples are generally heavy, a lot of physical strength will be consumed during long-term up and down transportation, which affects the sealing efficiency of the concrete samples. In view of this, the utility model proposes a sealing device for concrete impermeability testing. Utility Model Content

[0006] In order to overcome the above defects of the prior art, the utility model provides a sealing device for concrete impermeability test to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a sealing device for concrete impermeability test, comprising a base plate, a support plate is arranged on the top of the base plate, a turntable is arranged on the top of the support plate, a concrete sample is placed on the turntable, and the outer surface of the concrete sample is wrapped with plastic wrap, an axle rod is arranged between the support plate and the turntable, a solution cylinder is arranged on the surface of the base plate on one side of the support plate, a delivery pump is arranged on one side of the solution cylinder, a connecting pipe and a delivery pipe are arranged at the input and output ends of the delivery pump, respectively, a plurality of nozzles are installed on the delivery pipe, the input and output ends of the delivery pump are connected to the connecting pipe and the delivery pipe, respectively, wherein one end of the connecting pipe extends to the interior of the solution cylinder, the delivery pipe is an L-shaped structure, and a plurality of nozzles are connected to the delivery pipe.

[0008] It can be seen that the rotation of the turntable drives the concrete sample to rotate, and cooperates with multiple nozzles to spray sealant, so that the surface of the concrete sample is evenly sprayed with sealant to form a sealing effect.

[0022] Specifically, in this structure, when the concrete sample 26 is sealed for the anti-permeability test, the concrete sample 26 to be sealed is placed on the turntable 3. At this time, the turntable 3 can drive the concrete sample 26 to rotate. At the same time, the delivery pump 6 delivers the sealant inside the solution cylinder 5 through the connecting pipe 7 and the delivery pipe 8, and finally sprays it evenly on the surface of the concrete sample 26 through multiple nozzles 9 to form a seal. After spraying, the plastic wrap 27 is wrapped on the surface of the concrete sample 26.

[0023] As attached Figure 1 , 2As shown in , 4, one end of the bottom plate 1 is located at the rear side of the support plate 2 and is provided with an auxiliary structure, the auxiliary structure includes an adjustment cylinder 10, one end of the bottom plate 1 is located at the rear side of the support plate 2 and is provided with a rectangular groove 11, the adjustment cylinder 10 is installed inside the rectangular groove 11, and both ends of the adjustment cylinder 10 are provided with axle pins 12, and the adjustment cylinder 10 is rotatably connected inside the rectangular groove 11 through the axle pins 12; the surface of the adjustment cylinder 10 is provided with a concave plate 13, and a lifting plate 14 is movably provided inside the concave plate 13, and the two inner walls of the concave plate 13 are provided with mounting grooves 15, wherein A screw rod 16 is arranged inside one mounting groove 15, and a slide rod 17 is arranged inside the other mounting groove 15, a first motor 18 is arranged at one end of the screw rod 16, and a threaded block 19 and a slider 20 are arranged outside the screw rod 16 and the slider 17 respectively, and the output end of the first motor 18 is coaxially connected to the screw rod 16 inside one of the mounting grooves 15, and the threaded block 19 and the slider 20 are connected to the screw rod 16 and the slider 17 by threaded connection and sliding connection respectively, and the threaded block 19 and the slider 20 are fixedly mounted at both ends of the lifting plate 14 respectively.

[0024] Specifically, in this structure, since the concrete sample 26 is generally relatively heavy, it is laborious to carry the concrete sample 26 to the turntable 3. Therefore, the setting of this structure can assist the operator to carry the concrete sample 26 to the turntable 3 for sealing operation, and at the same time, it is convenient to carry out the sealed concrete sample 26, saving manpower. In the specific operation:

[0025] First, the concave plate 13 is turned over so that the adjustment cylinder 10 at the concave plate 13 rotates inside the rectangular groove 11 through the shaft pin 12, and the concave plate 13 is tilted and placed on the turntable 3. The operator places the concrete sample 26 inside the concave plate 13 and starts the first motor 18. The first motor 18 drives the screw rod 16 inside one of the installation grooves 15 to operate and moves the threaded block 19. The slider 20 is used to slide and guide the lifting plate 14 inside the concave plate 13 under the external sliding guidance of the slide rod 17. The movement of the lifting plate 14 can push the concrete sample 26 onto the turntable 3, thereby saving the operator's physical strength in carrying the concrete sample 26 from the ground to the turntable 3.

[0026] When the concrete sample 26 is sealed, the concave plate 13 can be turned over so that the concave plate 13 is not placed on the turntable 3, so as to avoid affecting the rotation and spraying operation of the concrete sample 26 driven by the turntable 3.

[0027] In a specific embodiment, as shown in the attached Figure 5As shown, a bearing 21 is provided at the bottom end of the shaft rod 4, and is rotatably connected to the surface of the support disk 2 through the bearing 21. The top of the shaft rod 4 is fixedly connected to the turntable 3. A gear ring 22 is provided on the outer fixed sleeve of the shaft rod 4. A gear plate 23 is provided on one side of the gear ring 22. A rotating rod 24 is provided at the bottom of the gear plate 23. A second motor 25 is provided at the bottom of the rotating rod 24. The second motor 25 is installed on the surface of the support disk 2, and the output end of the second motor 25 is coaxially connected with the rotating rod 24. The gear plate 23 and the gear ring 22 are meshed with each other.

[0028] Specifically, in this structure, the turntable 3 can be driven to rotate to achieve uniform spraying of the sealant on the surface of the concrete sample 26. Specifically, the second motor 25 drives the rotating rod 24 to rotate, and drives the gear plate 23 to rotate. The rotation of the gear plate 23 drives the gear plate 23 meshing therewith to rotate, and then drives the bottom end of the shaft rod 4 to rotate on the surface of the support plate 2 through the bearing 21, and the top end of the shaft rod 4 drives the turntable 3 to rotate, thereby driving the concrete sample 26 placed on the top of the turntable 3 to rotate, ensuring that the sealant on the surface of the concrete sample 26 is evenly sprayed.

[0029] Working principle of this utility model:

[0030] When the above structure is used in practice, when sealing the concrete sample 26 for impermeability, the concrete sample 26 needs to be placed on the turntable 3, and the turntable 3 is used to drive the concrete sample 26 to rotate, and the sealant sprayed by the nozzle 9 is sprayed on the surface of the concrete sample 26, and finally the plastic wrap 27 is used for wrapping. In the specific operation;

[0031] When the concrete sample 26 is carried to the turntable 3, the auxiliary structure can be used to reduce the burden of manual handling. The concave plate 13 is turned over so that the adjustment cylinder 10 at the concave plate 13 rotates inside the rectangular groove 11 through the shaft pin 12, and the concave plate 13 is tilted and erected on the turntable 3. The operator places the concrete sample 26 inside the concave plate 13 and starts the first motor 18. The first motor 18 drives the screw rod 16 inside one of the mounting grooves 15 to operate and moves the threaded block 19. The slider 20 is used to slide the lifting plate 14 inside the concave plate 13 under the external sliding guide of the slide rod 17. The movement of the lifting plate 14 can push the concrete sample 26 onto the turntable 3, thereby saving the operator's physical strength in carrying the concrete sample 26 from the ground to the turntable 3.

[0032] After the concrete sample 26 is carried to the turntable 3, the concave plate 13 is flipped again so that the concave plate 13 is no longer placed on the turntable 3. At this time, the second motor 25 drives the rotating rod 24 to rotate, and drives the gear plate 23 to rotate. The rotation of the gear plate 23 drives the gear plate 23 meshing therewith to rotate, and then drives the bottom end of the shaft rod 4 to rotate on the surface of the support plate 2 through the bearing 21, and the top end of the shaft rod 4 drives the turntable 3 to rotate, so that the concrete sample 26 placed on the top of the turntable 3 can be driven to rotate;

[0033] The delivery pump 6 delivers the sealant in the solution cylinder 5 through the connecting pipe 7 and the delivery pipe 8, and finally sprays it evenly on the surface of the concrete sample 26 through multiple nozzles 9 to form a seal. After spraying, the plastic wrap 27 is wrapped on the surface of the concrete sample 26.

[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
