Abstract
Description
Technical Field
[0001] The utility model relates to a cement density test auxiliary device, which is mainly used for assisting in filling cement samples into a Lee density bottle. Background Art
[0002] Cement is a common building material. It is made of limestone, clay and other materials after high-temperature calcination. It is widely used in the construction industry, mainly used in the preparation of concrete and the foundation construction of buildings. The quality of cement determines the quality of concrete and other materials to the greatest extent. Cement density test is a prerequisite test for testing the quality of cement products.
[0003] The cement density test is to pour a certain mass of cement into a Lewes flask filled with a sufficient amount of liquid medium. The volume of the liquid should be able to fully infiltrate the cement particles. According to Archimedes' principle, the volume of cement particles is equal to the volume of liquid it displaces, so the mass of cement per unit volume is calculated as the density. In the test, the liquid medium is anhydrous kerosene or other liquids that do not react with cement. During the test phase, a reagent spoon is often used to slowly load the sample into the Lewes flask. The speed is slow, and the cement sample often blocks the Lewes flask tube during the process. It is necessary to restore the tube to a smooth state by knocking or inserting a glass rod. Not only is the detection efficiency low, but there is also a safety hazard of breaking the Lewes flask.
[0004] Based on this, we designed a cement density test auxiliary device to improve the adjustable high-frequency vibration, assist in the cement density test sample loading stage, improve test efficiency and reduce safety hazards. Utility Model Content
[0005] In view of the above-mentioned defects existing in the prior art, the utility model provides a cement density test auxiliary device which can solve the problem that the sample is easy to block the Lethe flask tube during cement density test, improve the detection efficiency, and reduce safety hazards.
[0006] The utility model is realized through the following technical scheme: a cement density test auxiliary device, characterized in that: it includes a bracket base, a test bench panel arranged on the upper part of the bracket base, a spring is respectively connected between the test bench panel and the bracket base at the four corners, a suspended uniaxial exciter is arranged at the bottom of the test bench panel, at least one test bracket device is arranged on the upper part of the test bench panel, each test bracket device includes a Levin flask bracket, a Levin flask base, and a Levin flask fixing ring, the Levin flask bracket is two vertical poles fixed on the test bench panel, the poles are provided with threads, the Levin flask base is a bowl-shaped structure made of rubber material, the Levin flask base is arranged between the two poles, the Levin flask fixing ring is a circular ring structure, connecting sleeves are symmetrically connected on both sides of the circular ring, the two connecting sleeves are respectively movably mounted on the two poles, and the two poles are respectively threaded with fixing nuts.
[0007] When the utility model is working, the Lee's pycnometer is placed in the Lee's pycnometer base, the Lee's pycnometer fixing ring is mounted on the Lee's pycnometer, and the connecting sleeves at both ends of the Lee's pycnometer fixing ring are fixed by nuts arranged on two vertical rods, thereby fixing the Lee's pycnometer through the Lee's pycnometer fixing ring. The suspended uniaxial vibrator arranged at the bottom of the test bench panel can generate an exciting force to vibrate the test bench panel. During the stage of loading samples into the Lee's pycnometer in the cement density test, an exciting force is generated by the suspended uniaxial vibrator, and vibration can prevent the sample from blocking the Lee's pycnometer tube during loading, thereby ensuring a smooth loading process. The rubber Lee's pycnometer base can protect the safety of the Lee's pycnometer.
[0008] Furthermore, in order to ensure the safety of the Lee's pycnometer, a rubber layer is provided on the outside of the circular ring of the Lee's pycnometer fixing ring.
[0009] The beneficial effects of the utility model are as follows: the utility model has a simple structure and is reliable to use. During the stage of loading samples into the Lee's pycnometer in the cement density test, an exciting force can be generated by a suspended uniaxial vibrator, and vibration can prevent the sample from blocking the Lee's pycnometer tube during loading, thereby ensuring a smooth loading process. The problem of the sample easily blocking the Lee's pycnometer tube during the cement density test can be effectively solved, and the current problem of slow loading speed in the cement density test can be improved, thereby saving loading time and improving detection efficiency. The utility model can avoid unblocking the Lee's pycnometer tube by knocking or inserting a glass rod, thereby reducing safety hazards. BRIEF DESCRIPTION OF THE DRAWINGS

At least one test support device is arranged on the upper part of the test bench panel 1. In this embodiment, two test support devices are arranged, and multiple test support devices can also be arranged according to the test requirements. Each test support device includes a Levin flask support 9, a Levin flask base 7, and a Levin flask fixing ring 8. The Levin flask support 9 is two vertical rods 91 fixed on the test bench panel 1, and the vertical rods 91 are threaded. The base 7 of the Lee bottle is a bowl-shaped structure made of rubber material. The base 7 of the Lee bottle can accommodate the bottom part of the Lee bottle, and the base 7 of the Lee bottle is arranged between two upright poles 91. The fixing ring 8 of the Lee bottle is a circular ring structure, and the two sides of the circular ring structure are symmetrically connected with connecting sleeves 92.

The fixing ring 8 of the Lee bottle can be mounted on the Lee bottle 4 for fixing the Lee bottle 4. The diameter of the circular ring structure of the fixing ring 8 of the Lee bottle is smaller than the diameter of the spherical part of the lower part of the Lee bottle 4. The support base 5, the test bench panel 1, the upright poles 91, and the fixing ring 8 of the Lee bottle in the utility model are all made of steel. In order to ensure the safety of the Lee bottle 4, it is preferred that a rubber layer 10 is arranged on the outside of the circular ring of the fixing ring 8 of the Lee bottle.
