Building material hardness detection equipment

Abstract

The invention discloses building material hardness detection equipment which comprises a rack, a workbench, a lifting frame and a lifting mechanism and further comprises a mounting frame. The two ends of the mounting frame are connected with the lifting frame through overload protection mechanisms correspondingly, a pressure sensor is connected to the lower portion of the mounting frame, and a fixing piece is connected to the lower portion of the pressure sensor. A pressing head is connected below the fixing piece. Each overload protection mechanism comprises a bottom plate, an I-shaped piece, a reset assembly, a pair of floating pieces and a pair of resistance increasing assemblies, the bottom plate is fixedly installed on the lifting frame, the I-shaped piece is fixedly arranged on the bottom plate, a pair of extension rods connected to the end of the mounting frame abut against the two side walls of a stand column part of the I-shaped piece respectively, the floating parts are symmetrically and slidably arranged on the two sides of the I-shaped part, the resistance increasing assemblies correspond to the floating parts in a one-to-one mode, and the reset assembly is used for carrying out reset operation on the overload protection mechanisms. When pressure is too large, the pair of overload protection mechanisms can act to enable the mounting frame to move upwards relative to the lifting frame, and the overload protection effect on parts of equipment is achieved.

Description

Technical field[0001]The present invention relates to the technical field of building materials detection equipment, and more particularly to a hardness detection device for building materials.Background technique[0002]In the construction of construction, there is a need for many building materials. Some hardness quality requirements for building materials are more strict, and these materials need to be used for hardness quality detection before construction to achieve these building materials, so hardness quality needs to be used. Detection equipment has a hardness quality test on the building materials to be detected. In order to ensure the quality of construction projects, the test personnel need to strictly detect building materials.[0003]At present, the detection of building materials is detected by the hardness detection of building materials. The existing building material hardness testing equipment is typically placed on the workbench, and then hits the sample to hardness de...

Problems solved by technology

[0003] At present, building materials are tested using building material hardness testing equipment. The existing building material hardness testing equipment usually places building materials on the workbench, and then moves the indenter down to test the hardness of the sample. Usually, during testing, There will be incidents where the testing equipment is overpressured due to failure, and the overpressure will cause damage to the testing equipment. Therefore, it is necessary to improve the existing building material hardness testing equipment
