Description

Technical Field

[0001] The present invention relates to the technical field of asphalt inspection, and in particular to an asphalt sampling device for a high-viscosity and high-elasticity modified asphalt swelling tank. Background Art

[0002] According to announcement number CN215178845U, an asphalt sampling device for a high-viscosity and high-elasticity modified asphalt swelling tank includes a support assembly disposed on one side of a sampling port of the modified asphalt swelling tank, the support assembly comprising a support base and a support rod vertically disposed on the support base, the top of the support rod being connected to a horizontally disposed crossbeam, the crossbeam being provided with an annular rotation support groove, a winding drum being sleeved on the crossbeam at a position located in the rotation support groove, the winding drum being located above the sampling port, the two ends of the winding drum being provided with a drum edge, the drum edge of the end of the winding drum remote from the support rod being connected to a hand crank, a steel wire rope being wound around the winding drum, the free end of the steel wire rope being connected to a full-range sampler, and a lifting rod for connecting the steel wire rope to the top of the full-range sampler. By rotating the hand crank, the winding drum can be rotated about the crossbeam, tightening the steel wire rope on the winding drum, thereby removing the full-range sampler, making sampling more labor-saving for the operator.

[0003] The above technical solution uses a rope to lower the sampling bucket into the swelling tank for sampling. However, this sampling method can only achieve sampling when the sampling bucket is completely immersed in the asphalt solution. However, the sampling bucket generally tends to float on the asphalt surface, making sampling inconvenient. Therefore, we propose an asphalt sampling device for a high-viscosity and high-elasticity modified asphalt swelling tank to solve the above-mentioned problems. Summary of the Invention
