Description

Technical Field

[0001] The utility model relates to the technical field of concrete test block detection, in particular to a pressurizing device for testing raw materials of highway engineering. Background Art

[0002] Sampling for civil engineering tests is a major way to demonstrate the quality of civil engineering projects. Sampling and testing of concrete test blocks is an important part of civil engineering tests. It is necessary to perform pressure testing on standard-cured test blocks and same-cured test blocks to test the strength of concrete.

[0003] During the test, the test block needs to be placed on a pressure testing machine to pressurize the test block. Pressurization requires close observation of the concrete compression until the concrete test block breaks. When the concrete test block breaks, soil and rocks are likely to splash and affect the surrounding test personnel. In serious cases, it may cause harm to the test personnel, and affect the continuous observation of the test block compression, affecting the normal progress of the test. In view of this, we propose a pressurization device for highway engineering raw material testing. Utility Model Content

[0028] Working principle: During the pressure test of the test block, the test block is first placed on the receiving block 3, and then the equipment is started. The initial pressure on the test block will press the receiving block 3 downward to move downward. While moving, the receiving block 3 drives the sliding rod 302 to slide inside the arc groove 304, so that the receiving block 3 rotates and drives the connecting block 301 to move downward inside the connecting vertical groove 501, while pulling the movable baffle 5 out from the inside of the fixed baffle 4 to provide protection for the pressure test of the concrete test block. After the test is completed, the pressure on the receiving block 3 is released, and the receiving block 3 is reset under the action of the reset spring 305, and the movable baffle 5 is retracted into the fixed baffle 4. The inside of the fixed baffle plate 4, and then the broken test block is pushed down to the two sides of the fixed plate 2 so that it falls above the first receiving plate 8, so that the first receiving plate 8 is pressed and moves downward on the outer surface of the first fixed shaft 9 and contacts the contact block 13, and the lower end of the second receiving plate 10 is further moved upward by pressing the contact block 13 to receive the broken test block, and the test block is released along the second receiving plate 10 to the inside of the storage box 7.
