Description

Technical Field

[0001] The utility model relates to the technical field of cement density testing instruments, in particular to a cement mortar vibrating table. Background Art

[0002] The compaction table is mainly used to compact materials and reduce air and gaps in the materials. Cement mortar compaction tables are often used to compact cement mortar into cement test blocks before the density test of the cement test blocks, which is beneficial for testing the cement mortar and then improving the quality of cement used in construction, which is conducive to achieving the purpose of exquisite construction and green building construction.

[0003] After searching, a Chinese patent discloses a mortar specimen forming and compacting table (authorization announcement number CN202033233U), which includes two bases, one of which is provided with a pillar, an arm is hinged on the pillar, and the other end of the arm is connected to a bracket, the upper part of the bracket is provided with a mold sleeve and a clamp, the lower part of the bracket is provided with a protrusion and a driven wheel, and the other base is provided with a column, a motor is provided on the column, and a cam is provided on the power output shaft of the motor, and the cam is engaged with the driven wheel; when working, the motor drives the cam to rotate, and the cam drives the driven wheel to rotate. During the rotation of the cam, the bracket first rises, and after reaching the highest point, the bracket falls, thereby generating vibration, so that the cement mortar is compacted under the action of the vibration force. Although this patented technology is easy to use, accurate in counting, and has good compaction effect.

[0004] However, the above device still has some shortcomings in actual use. The most obvious one is that the above mortar specimen forming and compaction table uses the use of clamps to achieve the purpose of fixing the mold sleeve, but only fixes the mold sleeve in the vertical direction, and does not fix the lateral position of the mold sleeve. When the up and down vibration amplitude of the mold sleeve is greater than the static friction between its upper part and the clamp, it may cause the mold sleeve to slip sideways. After the mold sleeve deviates from the compaction center position, it will affect the test effect of the cement density. Utility Model Content
