Description

Spindle quick-release device for detecting adhesive force drawing strength Technical Field The utility model relates to the technical field of road asphalt adhesive force drawing test, in particular to a spindle quick-release device for detecting adhesive force drawing strength. Background The asphalt adhesion pullout test is a key means for evaluating asphalt performance and its application value is not variable. Firstly, the test can accurately measure the core characteristics of asphalt such as viscosity, hardness and elasticity, and the like, and provide data support for the overall asphalt performance. And secondly, through a drawing test, the quality of the asphalt mixture and raw materials thereof can be effectively evaluated, potential quality problems can be timely found and processed, and the safety and stability of road construction are ensured. In addition, the test can also predict the durability and long-term performance of asphalt, and provides scientific basis for decision making of pavement construction. Finally, comparing the test result with the standard, and verifying whether the asphalt performance reaches the standard or not, and further controlling the construction quality. In summary, the asphalt drawing test plays a vital role in asphalt performance evaluation, and in particular plays an important role in ensuring engineering quality, quality control, prevention and maintenance, material performance evaluation, safety and durability evaluation, and the like, and is an essential part in road construction. Currently, the full-automatic digital display drawing type adhesive force detector of DeFelsko in the United states is widely applied to the test and detection of the adhesive force drawing strength of asphalt binders. When drawing detection is completed, the detection spindle needs to be taken out from the quick sleeve, but because asphalt binder exists between the spindle and the sleeve, the taking out and the taking out are difficult, usually, a detection person uses a hand button or uses tools such as a screwdriver to carry out shoveling, so that a lot of inconvenience is clearly added to indoor and outdoor detection processes, and the detection efficiency is reduced while the hidden operational safety trouble is brought. Disclosure of Invention In order to solve the problem that the spindle is difficult to take out from the sleeve in the process of detecting the adhesive force drawing strength of asphalt, the utility model provides the spindle quick-release device for detecting the adhesive force drawing strength, which has the advantages of small size, portability and capability of quickly and safely taking out the spindle from the sleeve.
