Abstract
Description
Technical Field
[0001] This utility model relates to the field of automatic locking beam deployment and retraction, specifically an automatic locking beam deployment and retraction device under extremely cold working conditions. Background Technology
[0002] "Locking beam" is a common term in the engineering field, especially in buildings, bridges, or large structures. Its core function is to achieve stable connection and fixation of the beam through a specific mechanism to prevent displacement or deformation. The automatic locking beam deployment and deployment device is an advanced device that combines mechanical control, sensor technology, automated drive, and intelligent algorithms. It is mainly used to realize the automatic deployment (locking) and deployment (unlocking) of locking beams. By reducing manual intervention, improving operational accuracy and response speed, this device significantly improves the safety and efficiency of engineering structures (such as bridges, buildings, and large equipment) during the construction and operation phases.
[0003] Hydraulic transmission is a transmission method that uses liquid pressure to transmit power and motion. Since hydraulic cylinders can easily generate thrust of several tons to hundreds of tons, most automatic locking beam deployment and retraction devices use hydraulic transmission for adjustment. However, most traditional hydraulic automatic locking beam deployment and retraction devices have limited functionality and lack the effect of heating and heat preservation of hydraulic oil. In extremely cold conditions, the viscosity of hydraulic oil increases exponentially with decreasing temperature (e.g., the viscosity of mineral oil may exceed 10,000 cSt at -20℃). When the ambient temperature is close to or below the pour point of hydraulic oil (e.g., -30℃), the oil will exhibit waxy precipitation or semi-solidity. In mild cases, the waxy components in the oil will precipitate at low temperatures, clogging filters or small pipelines. In severe cases, the pump will have difficulty drawing oil, resulting in cavitation, which will lead to pump wear, increased noise, or even burnout. Utility Model Content

In extremely cold conditions, the viscosity of hydraulic oil increases exponentially as the temperature decreases.
