Problems solved by technology

[0003] The cable car is generally in the air between the mountains, and the safety risk index will increase in the case of strong winds. In the prior art, there is no algorithm for the risk index of the cable car high wind, which makes this risk index unable to be better evaluated, and thus cannot To achieve the effect of further improving the safety of cable car use

Embodiment 1

[0052] References (Huangshan, 2018), based on experience, the default values ​​of each parameter are set as attached figure 1 Table 1. The wind direction angle is obtained by calculating the angle between the actual wind direction data and the running direction of the cable car.

[0053] After calculating the risk index I, according to figure 2 Table 2 can be obtained four kinds of cable car wind risk early warning levels of certain risk, high risk, high risk and very high risk.

[0054] The data of the present invention is introduced as:

[0055] 1. Introduction to wind speed data

[0056] In order to verify the early warning effect of the risk index, the study used gridded observation data and forecast data in the Huashan and Huangshan areas (data sources and related parameters to be supplemented). According to historical observation records, the Huashan area selected the strong wind weather process on September 11 and December 31, 2019 as a research case, and the Huang...

Abstract

The invention discloses a cable car gale risk index setting and grading method, which is characterized in that a four-person hanging box is taken as an object, a cable car gale risk early warning index is designed into a formula containing I as a risk index and R representing a coefficient, wherein the coefficient uses a formula that contains: rho representing air density; S representing the side windward area of the cable car lift car; n representing the lateral wind resistance of the cable car lift car; v being wind speed; alpha representing a wind direction angle; M representing the weight of the cable car lift car; and g representing the gravitational acceleration. Four cable car gale risk early warning levels are obtained after the risk index I is calculated, and the four cable car gale risk early warning levels include certain level of risks, middle risks, high risks and very high risks. According to the cable car gale risk index algorithm provided by the invention, the cable car gale risk index can be better evaluated, and the use effect of further improving the use safety of the cable car is further achieved.

Description

technical field [0001] The invention relates to a method for formulating a strong wind risk index of a cable car and a method for classifying it, and belongs to the technical field of cable cars. Background technique [0002] The cable car is driven by the driving machine to drive the steel wire rope, and the traction carriage runs along the track laid on the ground and has a certain slope to lift or lower the transport machinery of people and goods. It is mostly used as a means of transportation in industrial and mining areas, cities or scenic spots. [0003] The cable car is generally in the air between the mountains, and the safety risk index will increase in the case of strong winds. In the prior art, there is no algorithm for the risk index of the cable car high wind, which makes this risk index unable to be better evaluated, and thus cannot The use effect of further improving the use safety of the cable car is achieved. Therefore, there is an urgent need for a cable ...
