Description

Technical Field

[0001] This utility model relates to the field of asphalt loading and unloading, and more specifically, to a modified asphalt loading system. Background Technology

[0002] With the rapid development of highway construction and the transportation industry, modified asphalt has become a key material in modern road construction, improving road performance, extending pavement service life, and enhancing crack resistance. Modified asphalt is commonly used in the construction of important infrastructure such as highways, airport runways, and bridges, and its superior high-temperature stability, anti-aging properties, and fatigue resistance have led to its widespread application in various traffic environments. However, with the continuous growth in demand for modified asphalt, traditional asphalt production and loading methods are gradually failing to meet the increasing requirements for efficiency, precision, and safety.

[0003] In existing asphalt loading systems, common technical solutions often rely on manual operation or semi-automated loading methods. These methods are not only inefficient but also susceptible to human factors, resulting in errors during loading and making accurate measurement difficult. Furthermore, traditional loading processes often fail to fully consider the high-temperature characteristics of asphalt, posing significant safety risks to operators, especially when loading high-temperature liquid asphalt. The high viscosity and high temperature of asphalt greatly increase the difficulty of operation, potentially leading to asphalt leaks, pollution, or even accidents, posing significant threats to personnel safety and environmental protection.

[0004] Weighing equipment in traditional loading systems often lacks sufficient accuracy and stability, especially in high-temperature and harsh environments. The performance of weighing sensors can be affected, leading to inaccurate weighing results. This not only directly impacts loading accuracy but can also result in substandard asphalt being incorrectly loaded into transport vehicles, consequently affecting road construction quality and service life.

[0005] Furthermore, the loading arm structure in an asphalt loading system, as a crucial component for liquid asphalt transportation, directly impacts the smooth operation of the entire loading process due to its design precision, flexibility, and sealing performance. Existing loading arm actuator designs typically cannot effectively prevent liquid asphalt leakage. Moreover, due to the high-temperature characteristics of asphalt, the loading arm may experience thermal expansion and deformation during use, leading to poor sealing at pipe connections. In addition, the inconvenience of connecting and disassembling the loading arm also affects loading efficiency, especially in the handling of liquid and gaseous pipelines. Improper handling of the mixing and emission of liquid and gaseous asphalt can easily cause safety hazards and environmental pollution. Utility Model Content
