Description

Technical Field

[0001] The utility model belongs to the technical field of concrete antifreeze performance detection, in particular to a concrete antifreeze performance detection device. Background Art

[0002] The rapid freeze-thaw tester is a test device designed and manufactured to test the frost resistance of concrete. It is usually used to measure the concrete's ability to withstand damage caused by repeated cycles of freezing and thawing in water.

[0003] When using a rapid freeze-thaw tester, the test piece needs to be placed in a test barrel made of rubber material, and clean water is added to the test barrel. The test barrel is placed in the instrument to conduct the test. Since the test barrel needs to frequently come into contact with liquid, in order to reduce the corrosiveness of the liquid to the test barrel, the test barrel is mostly made of rubber material. After long-term use, a test barrel made of rubber material is prone to significant deformation, making it difficult to place the test piece in subsequent use. At the same time, if the test piece is forcibly placed in the test barrel, the side wall of the test barrel will squeeze the test piece, making it difficult to remove the test piece.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0006] A concrete antifreeze performance testing device comprises a test barrel, a plurality of fixed sleeves with equal spacing are fixedly installed on the outside of the test barrel, a steel frame is fixedly sleeved between the fixed sleeves at the same height, and steel bars are fixedly installed at the corners between the plurality of steel frames;

[0007] A built-in slot body is fixedly installed at the bottom of the inner wall of the test barrel, a push rod is movably inserted at the top of the inner wall of the built-in slot body, a support plate is fixedly installed at the top of the push rod, and a convex block is fixedly installed at the top of the support plate;

A baffle is fixedly installed on one end of the connecting plate, and the baffle is slidably connected to the side wall of the test barrel. A drain outlet is opened at the bottom of one side of the baffle, and the baffle and the drain outlet are adapted to each other.

[0009] The test barrel of the device is connected to the steel frame through a fixed sleeve, and the test barrel is supported by the strength of the steel frame to prevent the test barrel from being significantly deformed after long-term use.

[0010] As a preferred embodiment of the utility model, the inner wall of the test barrel is provided with a plurality of protrusions distributed at equal intervals, and the moisture can fully contact the test piece through the protrusions of the protrusions on the side wall of the test barrel.

[0011] As a preferred embodiment of the utility model, a piston is fixedly installed at the bottom of the push rod, a spring is movably sleeved on the push rod, and both ends of the spring are respectively fixedly installed on the top of the piston and the top of the inner wall of the built-in groove body. The spring is always in a compressed state. After the removal is completed, the piston is released, and the elastic force of the spring drives the piston to move and reset, and the piston pulls the support plate and the connecting plate to reset through the push rod.

[0012] As a preferred embodiment of the utility model, the piston is slidably connected to the inner wall of the built-in groove body, and a through hole is opened on the side of the piston which passes through the upper and lower parts. A sealing gasket is fixedly installed on the bottom of the inner wall of the built-in groove body, and the top outer edge of the sealing gasket is chamfered.

When the measurement is completed, the test piece needs to be taken out. At this time, the piston is lifted up, the piston moves upward for a distance, and the through hole is separated from the sealing gasket. The pressure on the upper and lower sides of the piston is balanced. After taking out, the piston moves to the bottom and the sealing gasket blocks the through hole to prevent liquid from entering the built-in groove body during subsequent use.

[0013] As a preferred embodiment of the present invention, the built-in slot body is made of metal, and the built-in slot body made of metal reduces deformation caused by long-term use.

[0014] As a preferred embodiment of the present invention, the test barrel is made of rubber material. The test barrel made of rubber material can effectively reduce the corrosiveness of the antifreeze when in contact with the antifreeze.

[0027] A built-in tank body 6 is fixedly installed at the bottom of the inner wall of the test barrel 1, a push rod 7 is movably inserted at the top of the inner wall of the built-in tank body 6, a support plate 8 is fixedly installed at the top of the push rod 7, and a convex block 9 is fixedly installed at the top of the support plate 8;

[0028] A connecting plate 10 is fixedly installed on the top of the top rod 7, and the connecting plate 10 is located at the bottom of the support plate 8. A baffle 11 is fixedly installed on one end of the connecting plate 10, and the baffle 11 is slidably connected to the side wall of the test barrel 1. A drain outlet 12 is opened at the bottom of the test barrel 1 on one side of the baffle 11, and the baffle 11 and the drain outlet 12 are adapted to each other.

[0029] The test barrel 1 of the device is connected to the steel frame 2 via a fixing sleeve 4, and the test barrel 1 is supported by the strength of the steel frame 2 to prevent the test barrel 1 from being significantly deformed after long-term use.

[0030] like Figures 1 to 5 As shown, in a specific embodiment, a plurality of equally spaced protrusions 5 are provided on the inner wall of the test barrel 1. In this configuration, the protrusions 9 and the protrusions 5 on the side wall of the test barrel 1 allow the moisture to fully contact the test piece.

[0031] like Figures 1 to 5As shown, further, a piston 14 is fixedly installed at the bottom of the push rod 7, and a spring 13 is movably sleeved on the push rod 7. The two ends of the spring 13 are respectively fixedly installed on the top of the piston 14 and the top of the inner wall of the built-in groove body 6, and the spring 13 is always in a compressed state. In this setting, after the removal is completed, the piston 14 is released, and the elastic force of the spring 13 drives the piston 14 to move and reset, and the piston 14 pulls the support plate 8 and the connecting plate 10 to reset through the push rod 7.

[0032] like Figures 1 to 5 As shown, further, the piston 14 is slidably connected to the inner wall of the built-in groove body 6, and a through hole 15 is opened on the side of the piston 14, which passes through from top to bottom. A sealing gasket 16 is fixedly installed at the bottom of the inner wall of the built-in groove body 6. The top outer edge of the sealing gasket 16 is cut corners, and the sealing gasket 16 is adapted to the shape of the piston 14.

At this time, the piston 14 is lifted up, and the piston 14 moves upward for a distance, and the through hole 15 is separated from the sealing gasket 16. The pressure on the upper and lower sides of the piston 14 is balanced, and the piston 14 is moved. The piston 14 drives the push rod 7 to move, and the push rod 7 drives the connecting plate 10 to move. The connecting plate 10 drives the baffle 11 to rise, so that the drain port 12 is opened, and the water in the test barrel 1 flows out through the drain port 12. The push rod 7 moves and drives the supporting plate 8 to rise. The supporting plate 8 drives the test piece to rise through the protrusion 9, so that it is convenient for the staff to take out the test piece;

[0037] After the removal is completed, the piston 14 is released, and the elastic force of the spring 13 drives the piston 14 to move and reset. The piston 14 pulls the supporting plate 8 and the connecting plate 10 to reset through the push rod 7. The connecting plate 10 drives the baffle 11 to reset and block the drain port 12. At the same time, the piston 14 moves to the bottom and makes the sealing gasket 16 block the through hole 15 to prevent liquid from entering the interior of the built-in tank 6 during subsequent use.
