Description

Technical Field

[0001] The utility model relates to the technical field of concrete testing, in particular to a sealing device for an anti-seepage test piece. Background Art

[0002] Concrete is a general term for engineering composite materials that are made of aggregates bonded together by cementitious materials. During the production and processing of concrete, it is necessary to conduct a permeability test on the concrete specimens.

[0003] Before the concrete impermeability test, it needs to be sealed first. However, the bottom of the base mold sleeve on the existing test bench is two independent entities. The water of the specimen test is easy to leak out from the connection between the base and the mold sleeve. The staff will set a sealing ring between them, but the sealing effect is general, which still makes it easy for water to seep from the side of the specimen frequently, resulting in the termination and invalidation of the test results. Summary of the invention

[0004] The utility model aims to provide a sealing device for a test piece for an impermeability test, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A sealing device for a waterproof test specimen comprises a processing table, a controller and an electric push rod; a base is fixedly installed on the top of the processing table, a mold sleeve is fixedly connected to the top of the base, electric push rods are fixedly installed on the top of the processing table at both ends of the mold sleeve, a top plate is fixedly connected to the top of the electric push rod, and the top plate is located on the top of the mold sleeve, a sealing ring is attached to the inside of the top plate, and the sealing ring fits with the top of the mold sleeve, a fixed frame is movably installed on the periphery of the mold sleeve, an exhaust component is arranged on the top of the processing table on one side of the base, a controller is fixedly connected to the top of the processing table at one end of the base, and the controller is located on the other side of the electric push rod.

[0007] The test piece can be placed by installing the mold sleeve, which is convenient for the subsequent anti-seepage test of the test piece. The electric push rod can be used to drive the top plate to move upward or downward. After the test piece is placed in the mold sleeve, the electric push rod can be used to drive the top plate to move downward, so that the test piece can be automatically squeezed downward, so that the test piece is completely moved to the inside of the mold sleeve, without the need for the user to manually press the test piece, thereby reducing the burden on the user. The top plate and the mold sleeve can be sealed by installing a sealing ring to prevent water from leaking from the connection part between the top plate and the mold sleeve during the test of the test piece. The contact area between the mold sleeve and the base can be expanded by installing a fixed frame, thereby improving the sealing effect between the mold sleeve and the base. The air between the fixed frame and the base can be exhausted by installing an exhaust component, further improving the sealing effect between the mold sleeve and the base. The electric push rod and the electric push rod can be controlled by a controller, thereby facilitating the user to use the device.

[0008] A further improvement of the technical solution of the utility model is that: the vacuum component includes an outer shell, which is fixedly connected to one side of the base, a second partition is fixedly installed inside the outer shell, a first partition is fixedly connected inside the outer shell on one side of the second partition, a slide plate is slidably installed between the second partition and the first partition, an electric push rod is fixedly connected to the top of the outer shell, and the electric push rod extends into the interior of the outer shell and is fixedly connected to the top of the slide plate, a first baffle is movably installed inside the outer shell through a first spring, and the first baffle is in contact with one side of the first partition, and a second baffle is movably connected to the other side of the second partition through a second spring, and the second baffle is in contact with the inner wall of the outer shell.

[0009] The above-mentioned technical scheme is adopted. In this scheme, the interior of the shell can be divided into three parts by installing the first partition and the second partition, so as to facilitate the normal subsequent air extraction work. The electric push rod can be used to drive the slide plate to move up and down inside the shell. When the slide plate moves upward, the air between the fixed frame and the base can be sucked into the interior of the shell. When the slide plate moves downward, the air inside the shell can be discharged from the circular hole opened on one side. The first baffle can be installed by using the first spring, and the circular hole opened on the surface of the first partition can be blocked by the first baffle. The second baffle can be installed by using the second spring, and the circular hole opened on the surface of the second partition can be blocked by the second baffle to prevent air from circulating inside the shell.

[0010] A further improvement of the technical solution of the utility model is that circular holes are opened on both sides of the shell, and circular holes are opened on the surfaces of the first partition plate and the second partition plate, and the circular holes of the shell have the same radius as the circular holes opened on the surfaces of the first partition plate and the second partition plate, and are all located on the same horizontal line.

[0011] The above technical solution is adopted. In this solution, circular holes are opened on the surfaces of the outer shell, the first partition plate and the second partition plate to facilitate the circulation of air inside the outer shell, thereby facilitating subsequent air extraction work.

[0012] A further improvement of the technical solution of the utility model is that a circular groove is provided inside the fixing frame, a groove is provided inside the base, and two ends of the groove are respectively connected to the circular hole on the other side of the shell and the bottom of the circular groove of the fixing frame.

[0013] The above technical solution is adopted. In this solution, by opening a circular groove inside the fixing frame and a groove inside the base, the air between the fixing frame and the base can be easily circulated to the inside of the shell, thereby realizing subsequent air extraction work.

[0014] A further improvement of the technical solution of the utility model is that a rubber pad is attached to the interior of the fixed frame, and the rubber pad fits with the top of the base, and the rubber pad is made of a material that can deform and rebound.

[0015] The above technical solution is adopted. In this solution, a slight gap can be left between the fixed frame and the base by installing the rubber pad. At the same time, the rubber pad itself is made of a material that can deform and rebound, which can facilitate the fixed frame to move on the top of the base.

[0016] A further improvement of the technical solution of the utility model is that a plurality of third springs are fixedly installed inside the mold sleeve, a connecting block is fixedly connected to the bottom of each third spring, and the connecting block is fixedly connected to the fixed frame.

[0017] The above technical solution is adopted. In this solution, the connection block can be installed by using the third spring, so that the fixed frame and the mold sleeve can be connected, so that the position of the fixed frame on the periphery of the mold sleeve can be limited.

[0018] A further improvement of the technical solution of the utility model is that a clamping block is fixedly installed on the bottom of the top plate, and the clamping block is embedded in the interior of the mold sleeve.

[0019] The above technical solution is adopted. In this solution, the contact area between the top plate and the mold sleeve can be expanded by installing the card block, preventing water from seeping out from between the top plate and the mold sleeve during the anti-seepage test, thereby further improving the sealing effect between the top plate and the mold sleeve.

[0020] Due to the adoption of the above technical solution, the utility model has achieved the following technical progress compared with the prior art:

[0021] 1. The utility model provides a sealing device for a test piece for an impermeability test. Through the cooperation among an air extraction component, a rubber pad and a connecting block, the air between the base and the fixed frame can be exhausted, thereby improving the sealing effect between the base and the fixed frame and ensuring the normal progress of the test work.

[0022] 2. The utility model provides a sealing device for a permeability test specimen, which utilizes a clamping block and a sealing ring to prevent water from seeping out from between the top plate and the mold sleeve during the permeability test, thereby further improving the sealing effect between the top plate and the mold sleeve.

[0023] 3. The utility model provides a sealing device for an impermeability test specimen, which can completely squeeze the test specimen into the interior of the mold sleeve by using an electric push rod and a top plate, without the need for the user to manually press the specimen, thereby reducing the burden on the user.
