A constant temperature hydrostatic balance and using method thereof

Abstract

The invention discloses a constant temperature hydrostatic balance which comprises a frame, wherein the frame comprises a mounting plate and support plates located on the two sides of the lower end of the mounting plate; a balance is arranged on the mounting plate; a mesh basket in known density is hung under the balance; a lifting plate which is in sliding connection with the support plates along the vertical direction is arranged between the two support plates; a driving mechanism which is used for driving the lifting plate to move along the vertical direction is arranged on the support plates; a measuring tank is fixedly arranged on the lifting plate; an overflow barrel which is fixedly arranged on the measuring tank is arranged in the measuring tank; and the projection of the mesh basket along the vertical direction is located in the overflow barrel. The test error caused by water flashing or human factor is avoided in the test process, so that the density of the tested piece is more accurate.

Description

technical field [0001] The invention relates to the field of concrete testing equipment, in particular to a constant temperature hydrostatic balance and a method for using the same. Background technique [0002] In scientific research work, especially civil engineering measurement, the electronic hydrostatic balance is an indispensable measurement tool for the measurement personnel to measure the specific gravity and volume of the sample. [0003] At present, when testing the density of asphalt concrete, a hydrostatic balance is usually used, and this hydrostatic balance includes a balance, an overflow cylinder located directly below the balance, a bracket for erecting the balance directly above the overflow cylinder, and a hanger at the bottom of the balance. The basket used to load the test piece, the overflow tank is provided with a water inlet and a drain, the basket is not in contact with the bottom of the overflow tank. When testing the density, first make the water l...

Problems solved by technology

[0004] However, in actual operation, when the asphalt concrete block used for the test is put into the basket, if the test piece is directly put into the basket, since the basket is in the water, the impact force and gravity of the test piece will cause water splashes to come out. , affecting the accuracy of the test; if the test piece is slowly put into the basket by hand, although the test piece will not hit the water surface and cause the water to come out, the hand will be immersed in the basket, causing too much water to overflow, resulting in the experimental data large error
