Abstract

The invention discloses drilling and sampling equipment for engineering detection, and belongs to the field of engineering sampling. The drilling and sampling equipment comprises a base, vertical frames are symmetrically mounted on the upper side of the base, a plurality of universal wheels are mounted on the lower side of the base, a lifting plate is arranged on the upper side of the base, the two ends of the lifting plate are slidably mounted on the vertical frames respectively, the vertical frames are rotatably provided with lifting screw rods, the lifting screw rods and the lifting plate are in threaded installation, the lifting screw rods are driven by a lifting motor, the lifting plate is rotatably provided with a sampling rotary drum, the sampling rotary drum is driven by a driving motor, and the bottom end of the sampling rotary drum is provided with a plurality of crushing cones. According to the device, local sampling operation can be carried out on a concrete slab, the sampled sample is cylindrical, the shape is well preserved, the sampling process is simple, an acetone solution is sprayed during sampling, and a protective film can be formed after the acetone solution is dried so that the physical and chemical properties of the sample are prevented from being damaged due to the influence of the external environment.

Description

technical field [0001] The invention relates to the technical field of engineering sampling, in particular to a drilling sampling device for engineering testing. Background technique [0002] During the construction process of the project, it is necessary to take partial sampling of the concrete slab and test the taken concrete samples, including analyzing the physical and chemical properties of its main components, performing hardness tests, tensile tests and other mechanical performance tests on them. [0003] After retrieval, Chinese Patent No. CN 214309634 U discloses a drilling sampling device for engineering material detection, which includes a sampling column, and a sampling cavity is provided at the lower end of the sampling column, and it is characterized in that: the sampling cavity is along the axial direction of the sampling column There is a blocking plate slidingly connected with the outer wall of the sampling column along the axial direction of the sampling co...
